Technical Field

The present disclosure relates to a connector having a plurality of core resin portions on which terminals are arranged and an outer resin portion covering the plurality of core resin portions.

Background

The connector is used when various control components are electrically wired to the control device. The connector has a plurality of terminals that are electrically connected. In addition, when a plurality of terminals are arranged in a plurality of layers, insert molding may be performed in stages in order to facilitate the arrangement of the terminals when insert molding of a resin material is performed. In this case, insert molding of a plurality of core resin portions in which the terminals of each layer are arranged is performed as one-shot molding. Next, as secondary molding, insert molding of the outer resin portion in which the plurality of core resin portions are arranged is performed. Thus, a connector having a plurality of core resin portions arranged in the outer resin portion is molded. As such a connector, for example, a connector shown in patent document 1 is known.

Disclosure of Invention

Problems to be solved by the invention

However, in the connector, the end of the resin portion where the terminal is arranged is provided so as to protrude from the main body of the resin portion. In order to simplify the molding of the end portion of the resin portion, it is conceivable that the end portion of the resin portion is formed by a plurality of core resin portions, and the portions of the plurality of core resin portions constituting the end portion of the resin portion are exposed to the surface of the connector without being covered by the outer resin portion.

However, in this case, the outer resin portion is insert-molded in the molding die in which the core resin portion is disposed, and after the molded article is taken out from the molding die, there is no structure in which one end portions of the plurality of core resin portions are bound. Therefore, when the resin material constituting the outer resin portion is cooled and contracted, stress may act on one end portions of the plurality of core resin portions in a direction in which the one end portions of the plurality of core resin portions are to be separated from each other. In this case, the positions of the one end portions of the plurality of terminals protruding from the one end portions of the plurality of core resin portions may be shifted, and the electrical connection between the plurality of terminals may be defective.

The present disclosure has been made in view of the above problems, and provides a connector including: even when one end portions of the plurality of core resin portions are arranged outside the outer resin portion so as to overlap each other, it is possible to prevent the position of the one end portion of each terminal protruding from the one end portion of each core resin portion from being shifted.

Means for solving the problems

An aspect of the present disclosure is a connector including:

a 1 st terminal;

a 1 st core resin portion covering an intermediate portion of the 1 st terminal except for both end portions;

a 2 nd terminal;

a 2 nd core resin portion covering an intermediate portion of the 2 nd terminal except for both end portions; and

an outer resin part partially covering the 1 st core resin part and the 2 nd core resin part in a state of being overlapped with each other, を え,

One end of the 1 st terminal and one end of the 2 nd terminal are arranged parallel to each other along a 1 st direction,

one end portion of the 1 st core resin portion from which one end portion of the 1 st terminal protrudes and one end portion of the 2 nd core resin portion from which one end portion of the 2 nd terminal protrudes are disposed outside the outer resin portion so as to face each other at a boundary surface in a 2 nd direction orthogonal to the 1 st direction,

a clamping portion is formed in the outer resin portion, and the clamping portion clamps a part of one end portion of the 1 st core resin portion and a part of one end portion of the 2 nd core resin portion together,

the clamping part comprises: a 1 st embedded portion extending toward a tip end side in the 1 st direction, at least a part of which is embedded in a position other than the boundary surface in one end portion of the 1 st core resin portion; and a 2 nd embedded portion extending toward a tip end side in the 1 st direction, at least a part of which is embedded in a position other than the boundary surface in one end portion of the 2 nd core resin portion.

Effects of the invention

In the connector according to the first aspect, when the one end portions of the plurality of core resin portions are arranged outside the outer resin portion so as to overlap each other, it is desirable that the one end portions of the plurality of core resin portions are not separated from each other.

Specifically, the 1 st buried portion and the 2 nd buried portion of the clamping portion clamp a portion of each of the one end portion of the 1 st core resin portion and the one end portion of the 2 nd core resin portion facing each other in the 2 nd direction from both sides in the 2 nd direction. Thus, even when stress acts on one end of each core resin portion when the resin material constituting the outer resin portion is cooled and contracted outside the molding die when each core resin portion is fitted and the outer resin portion is molded, the one end of the 1 st core resin portion and the one end of the 2 nd core resin portion can be prevented from being separated from each other in the 2 nd direction by the clamping of the clamping portion.

In this way, in the connector according to the first aspect, when the outer resin portion is molded by fitting the core resin portions, the one end portions of the core resin portions disposed outside the outer resin portion are not separated from each other, and thus the position of the one end portion of each terminal is not displaced.

Therefore, according to the connector of the first aspect, even when the one end portions of the plurality of core resin portions are arranged outside the outer resin portion so as to overlap each other, the positions of the one end portions of the terminals protruding from the one end portions of the core resin portions can be prevented from being varied.

The connector 1 of the present embodiment will be described in detail below.

(connector 1)

As shown in fig. 1, the connector 1 of the present embodiment is used as a relay connector for relaying electric wiring when various control components 5 are electrically wired to a control device. The connector 1 constitutes a male connector provided with terminals 3A, 3B, 3C serving as conductor pins. One end portions 31A, 31B, 31C of the terminals 3A, 3B, 3C are connected to a control board 6 of the control device, and the other end portions 32A, 32B, 32C of the terminals 3A, 3B, 3C are connected to a female terminal of the female connector.

As shown in fig. 2 to 4, each of the terminals 3A, 3B, and 3C may be used for any purpose, such as control or power supply. The plurality of 1 st terminals 3A and the plurality of 2 nd terminals 3B of the present embodiment constitute terminals for control, and the plurality of 3 rd terminals 3C of the present embodiment constitute terminals for power supply. The other end portion 32C of the 3 rd terminal 3C is connected to an end portion 34C different from the one end portion 31C.

The plurality of 1 st terminals 3A and the plurality of 2 nd terminals 3B are arranged in a state of being overlapped in two layers in one end portions 20A, 20B, 20C of the core resin portions 2A, 2B, 2C and a part of the body portion. Further, a plurality of 3 rd terminals 3C are arranged in a state of being arranged on the side of the 1 st terminal 3A and the 2 nd terminal 3B in the one end portions 20A, 20B, 20C of the core resin portions 2A, 2B, 2C and a part of the body portion. The main body of each core resin portion 2A, 2B, 2C means a portion of each core resin portion 2A, 2B, 2C excluding one end 20A, 20B, 20C.

As shown in fig. 1, the connector 1 of the present embodiment includes a connector base portion 11, a connector projecting portion 12 projecting from the connector base portion 11, and a connector mounting portion 13 projecting from the connector base portion 11. The connector base portion 11 constitutes a main body portion of the connector 1 disposed to face the control board 6. The connector base portion 11 is a portion in which most of the main body portions of the 1 st core resin portion 2A, the 2 nd core resin portion 2B, and the 3 rd core resin portion 2C are covered with the outer resin portion 4.

The connector protrusion 12 is bent perpendicularly from the connector base portion 11. The connector protrusion 12 is disposed outside the outer resin portion 4 and includes a first end 20A of the 1 st core resin portion 2A, a first end 20B of the 2 nd core resin portion 2B, and a first end 20C of the 3 rd core resin portion 2C. The core resin portions 2A, 2B, and 2C and the outer resin portion 4 are disposed in the connector protrusion 12. The connector mounting portion 13 is a portion where the other end portions 32A, 32B, and 32C of the terminals 3A, 3B, and 3C are covered with the cylindrical portion 41 of the outer resin portion 4. The connector mounting portion 13 is mounted to the female connector.

As shown in fig. 1 to 4, the outer resin portion 4 is disposed in the connector protrusion 12 at a position adjacent to each base end side of the one end portion 20A of the 1 st core resin portion 2A, the one end portion 20B of the 2 nd core resin portion 2B, and the one end portion 20C of the 3 rd core resin portion 2C. The surfaces of the one end portions 20A, 20B, 20C of the core resin portions 2A, 2B, 2C are adjacent to the surface of the outer resin portion 4, forming the outer surface of the connector protrusion 12. In the intermediate portion 33 of each of the terminals 3A, 3B, and 3C, an exposed portion 35 is formed so as to be exposed to the outside of each of the core resin portions 2A, 2B, and 2C without being covered by each of the core resin portions 2A, 2B, and 2C. The exposed portion 35 is covered with the outer resin portion 4.

Since the outer resin portion 4 is disposed adjacent to the base end side of each of the one end portions 20A, 20B, and 20C of the core resin portions 2A, 2B, and 2C, a contraction force generated when the resin material constituting the outer resin portion 4 is molded is likely to act on the one end portions 20A, 20B, and 20C of the core resin portions 2A, 2B, and 2C.

As shown in fig. 1 and 3, each of the terminals 3A, 3B, and 3C is bent into a crank shape in accordance with the shapes of the connector base portion 11, the connector projecting portion 12, and the connector mounting portion 13. One end portions 31A, 31B, and 31C of the terminals 3A, 3B, and 3C are disposed to protrude from the connector base portion 11 to one side. The other end portions 32A, 32B, and 32C of the terminals 3A, 3B, and 3C are disposed to protrude from the connector base portion 11 to the other side.

(core resin parts 2A, 2B, 2C and outer resin part 4)

As shown in fig. 1, the core resin portions 2A, 2B, and 2C are formed by insert molding in which the terminals 3A, 3B, and 3C are arranged. The 1 st to 3 rd core resin portions 2A, 2B, and 2C are molded separately. The 1 st core resin portion 2A is formed by disposing a plurality of 1 st terminals 3A in a molding die and insert-molding a resin material in the molding die. The 2 nd core resin portion 2B is formed by disposing a plurality of 2 nd terminals 3B in a molding die and insert-molding a resin material in the molding die. The 3 rd core resin portion 2C is formed by disposing a plurality of the 3 rd terminals 3C in a molding die and insert-molding a resin material in the molding die. In this way, the core resin portions 2A, 2B, and 2C are formed as a primary molded product in which the terminals 3A, 3B, and 3C are fitted.

The connector 1 is formed by disposing the 1 st to 3 rd core resin portions 2A, 2B, 2C in a molding die, and insert-molding a resin material constituting the outer resin portion 4 in the molding die. The outer resin portion 4 is formed as a secondary molded product in which the core resin portions 2A, 2B, and 2C are fitted.

(configurations of one end portions 31A, 31B, 31C of the terminals 3A, 3B, 3C and one end portions 20A, 20B, 20C of the core resin portions 2A, 2B, 2C)

As shown in fig. 1 and 5, the 1 st direction D1, the 2 nd direction D2, and the 3 rd direction D3 are conveniently used to show the directions of the one end portions 31A, 31B, 31C of the terminals 3A, 3B, 3C and the one end portions 20A, 20B, 20C of the core resin portions 2A, 2B, 2C. The 1 st direction D1 shows a direction in which the one end portions 31A, 31B, and 31C of the terminals 3A, 3B, and 3C extend, and is set to a direction perpendicular to the connector base portion 11 of the connector 1 in which the body portions of the terminals 3A, 3B, and 3C are arranged. The 2 nd direction D2 and the 3 rd direction D3 show two directions orthogonal to the 1 st direction D1, and are set to be parallel to the connector base portion 11 of the connector 1. In the 1 st direction D1, the side of the one end portions 31A, 31B, and 31C of the terminals 3A, 3B, and 3C protruding from the core resin portions 2A, 2B, and 2C is referred to as the tip side, and the side opposite to the tip side in the 1 st direction D1 is referred to as the base side.

As shown in fig. 5 to 7, a plurality of the one ends 31A of the plurality of 1 st terminals 3A and a plurality of the one ends 31B of the plurality of 2 nd terminals 3B are arranged in a single layer along the 3 rd direction D3. In this embodiment, three 1 st terminals 3A and three 2 nd terminals 3B are arranged. One end 31A of the 1 st terminal 3A and one end 31B of the 2 nd terminal 3B are arranged in two layers so as to face each other in the 2 nd direction D2 and overlap each other in the 2 nd direction D2.

The one end 31C of the 3 rd terminal 3C is arranged adjacent to the one end 31A of the 1 st terminal 3A and the one end 31B of the 2 nd terminal 3B in the 3 rd direction D3, and a plurality of the terminals are arranged along the 2 nd direction D2. In other words, the one end portions 31C of the plurality of 3 rd terminals 3C are arranged in the 2 nd direction D2 with each other, and arranged in the 3 rd direction D3 together with the 1 st terminal 3A and the 2 nd terminal 3B. In this embodiment, the two 3 rd terminals 3C are arranged in line with the arrangement of the 1 st terminal 3A and the 2 nd terminal 3B which are overlapped by two layers.

One end 20A of the 1 st core resin part 2A covered with the plurality of 1 st terminals 3A and one end 20B of the 2 nd core resin part 2B covered with the plurality of 2 nd terminals 3B are aligned and integrated in the 2 nd direction D2. Further, the one end portion 20C of the 3 rd core resin part 2C covering the plurality of 3 rd terminals 3C is aligned and united in the 3 rd direction D3 with respect to the one end portion 20A of the 1 st core resin part 2A and the one end portion 20B of the 2 nd core resin part 2B.

(1 st to 3 rd clip parts 42A, 42B, 42C)

As shown in fig. 5, the 1 st clamp 42A is disposed on a side end surface 202 of one end 20A of the 1 st core resin part 2A and one end 20B of the 2 nd core resin part 2B, which is located on the opposite side of the 3 rd direction D3 perpendicular to the 1 st direction D1 and the 2 nd direction D2 from the side where the 3 rd core resin part 2C is disposed. The 1 st clamping portion 42A is formed across a boundary surface 201 between the one end 20A of the 1 st core resin portion 2A and the one end 20B of the 2 nd core resin portion 2B.

A 1 st narrow-width portion 44A is formed between outer resin portion 4 and 1 st sandwiching portion 42A in 1 st direction D1, and an outer width W2 of 2 nd narrow-width portion 44A in 2 nd direction D2 is narrower than an outer width W1 of 2 nd direction D2 between outer positions in embedded portions 43A and 43B of 1 st sandwiching portion 42A. In addition, in the case where the respective embedded portions 43A, 43B of the 1 st clamping portion 42A are not formed in parallel with the 1 st direction D1, the outer width W1 may be set to an outer width between outer positions among the base ends of the respective embedded portions 43A, 43B of the 1 st clamping portion 42A in the 1 st direction D1. The 1 st buried portion 43A and the 2 nd buried portion 43B constituting the 1 st clamping portion 42A are formed so as to branch from the 1 st narrow-width portion 44A in the 2 nd direction D2.

The 2 nd clamping portion 42B is disposed on the side end surface 202 located on the outer side in the 2 nd direction D2 of the one end portion 20A of the 1 st core resin part 2A and the one end portion 20C of the 3 rd core resin part 2C. The 2 nd clamping portion 42B is formed across the boundary surface 201 between the one end 20A of the 1 st core resin portion 2A and the one end 20C of the 3 rd core resin portion 2C.

A 2 nd narrow-width portion 44B is formed between the outer resin portion 4 and the 1 st direction D1 of the 2 nd sandwiching portion 42B, and an outer width W2 of the 2 nd narrow-width portion 44B in the 3 rd direction D3 is narrower than an outer width W1 of the 3 rd direction D3 between outer positions of the embedded portions 43A, 43C of the 2 nd sandwiching portion 42B. In addition, in the case where the respective embedded portions 43A, 43C of the 2 nd clamping portion 42B are not formed in parallel with the 1 st direction D1, the outer width W1 may be set to an outer width between outer positions among base ends of the respective embedded portions 43A, 43C of the 2 nd clamping portion 42B in the 1 st direction D1. The 1 st buried portion 43A and the 3 rd buried portion 43C constituting the 2 nd sandwiching portion 42B are formed to branch from the 2 nd narrow-width portion 44B in the 3 rd direction D3.

The 3 rd clamping portion 42C is disposed on the side end surface 202 located on the outer side in the 2 nd direction D2 of the one end portion 20B of the 2 nd core resin part 2B and the one end portion 20C of the 3 rd core resin part 2C. The 3 rd clamping portion 42C is formed across the boundary surface 201 between the one end 20B of the 2 nd core resin portion 2B and the one end 20C of the 3 rd core resin portion 2C.

A 3 rd narrow width portion 44C is formed between the outer resin portion 4 and the 1 st direction D1 of the 3 rd nip portion 42C, and an outer width W2 of the 3 rd narrow width portion 44C in the 3 rd direction D3 is narrower than an outer width W1 of the 3 rd direction D3 between outer positions of the embedded portions 43B, 43C of the 3 rd nip portion 42C. In addition, in the case where the respective embedded portions 43B, 43C of the 3 rd clamping portion 42C are not formed in parallel with the 1 st direction D1, the outer width W1 may be set to an outer width between outer positions of the base ends of the respective embedded portions 43B, 43C of the 3 rd clamping portion 42C in the 1 st direction D1. The 2 nd buried portion 43B and the 3 rd buried portion 43C constituting the 3 rd clamping portion 42C are formed so as to branch from the 3 rd narrow-width portion 44C in the 3 rd direction D3.

In fig. 5, the 3 rd narrow width portion 44C is formed on the back side of the 2 nd narrow width portion 44B, so the position of the 2 nd narrow width portion 44B is shown by including brackets for convenience. The outer widths W1, W2 of the 3 rd clip part 42C and the 3 rd narrow width part 44C are also the same as the outer widths W1, W2 of the 2 nd clip part 42B and the 2 nd narrow width part 44B.

By forming the narrow width portions 44A, 44B, and 44C, the corner portions 45 formed between the narrow width portions 44A, 44B, and 44C and the 1 st direction D1 of the sandwiching portions 42A, 42B, and 42C are caught by the core resin portions 2A, 2B, and 2C, and thus the core resin portions 2A, 2B, and 2C are less likely to be displaced from each other in the 1 st direction D1.

The cross-sectional area of each narrow portion 44A, 44B, 44C perpendicular to the 1 st direction D1 is preferably larger than the total cross-sectional area of each clip portion 42A, 42B, 42C perpendicular to the 1 st direction D1. The total cross-sectional area of each of the clamping portions 42A, 42B, and 42C orthogonal to the 1 st direction D1 is the total cross-sectional area of the pair of embedded portions 43A, 43B, and 43C of each of the clamping portions 42A, 42B, and 42C orthogonal to the 1 st direction D1. In this case, as shown in fig. 6, the resin material can easily flow from the narrow-width portion groove 22 for molding the narrow-width portions 44A, 44B, and 44C in the core resin portions 2A, 2B, and 2C to the grooves 21A, 21B, and 21C for molding the embedded portions 43A, 43B, and 43C.

The outer width W2 of the narrow width portions 44A, 44B, and 44C and the outer width W1 of the clamping portions 42A, 42B, and 42C may be the same. Instead of forming the narrow width portions 44A, 44B, and 44C in the outer resin portion 4, the clamping portions 42A, 42B, and 42C may be formed directly from the outer resin portion 4.

As shown in fig. 5 and 7, in the 1 st to 3 rd clamping portions 42A, 42B, and 42C, a portion embedded in the 1 st core resin portion 2A is referred to as a 1 st embedded portion 43A, a portion embedded in the 2 nd core resin portion 2B is referred to as a 2 nd embedded portion 43B, and a portion embedded in the 3 rd core resin portion 2C is referred to as a 3 rd embedded portion 43C. The 1 st to 3 rd buried portions 43A, 43B, and 43C of this embodiment are formed in parallel with the 1 st direction D1.

The 1 st to 3 rd buried portions 43A, 43B, and 43C may be formed obliquely to the 1 st direction D1. The 1 st to 3 rd buried portions 43A, 43B, and 43C are formed by flowing the resin material constituting the outer resin portion 4 into the 1 st to 3 rd grooves 21A, 21B, and 21C. Therefore, if the fluidity of the resin material for molding the outer resin portion 4 can be ensured at the time of molding the outer resin portion 4, the 1 st to 3 rd buried portions 43A, 43B, and 43C can be formed in various shapes such as a bent shape and a wave shape.

The 1 st buried portion 43A and the 2 nd buried portion 43B constituting the 1 st clamping portion 42A may be formed in a ring shape by connecting tip portions in the 1 st direction D1 to each other. The 1 st buried portion 43A and the 3 rd buried portion 43C constituting the 2 nd clamping portion 42B may be formed in a ring shape by connecting tip portions in the 1 st direction D1 to each other. The 2 nd buried portion 43B and the 3 rd buried portion 43C constituting the 3 rd clamping portion 42C may be formed in a ring shape by connecting tip portions in the 1 st direction D1 to each other.

As shown in fig. 5 and 7, the 1 st to 3 rd clamping portions 42A, 42B, and 42C are disposed at positions outside of the plane orthogonal to the 1 st direction D1 of the entire one ends 20A, 20B, and 20C of the 1 st to 3 rd core resin portions 2A, 2B, and 2C when the entire one ends 20A, 20B, and 20C of the 1 st to 3 rd core resin portions 2A, 2B, and 2C are viewed from the 1 st direction D1. The 1 st to 3 rd clamping portions 42A, 42B, and 42C are formed by exposing side end surfaces 202 of the 1 st to 3 rd core resin portions 2A, 2B, and 2C. The side end surface 202 is a surface located outside the 2 nd direction D2 and the 3 rd direction D3 in the 1 st to 3 rd core resin portions 2A, 2B, and 2C. By exposing the 1 st to 3 rd sandwiching portions 42A, 42B, and 42C to the side end surface 202, the structure of the molding die for molding the grooves 21A, 21B, and 21C can be simplified when molding the core resin portions 2A, 2B, and 2C.

The pair of embedded portions 43A, 43B, and 43C constituting the respective sandwiching portions 42A, 42B, and 42C may be embedded in the respective core resin portions 2A, 2B, and 2C, not in the side end surfaces 202 of the respective core resin portions 2A, 2B, and 2C. In this case, through-holes are formed in the core resin portions 2A, 2B, and 2C instead of forming the grooves 21A, 21B, and 21C.

As shown in fig. 5, the 1 st buried portion 43A is formed to the tip end surface in the 1 st direction D1 in the one end portion 20A of the 1 st core resin portion 2A. The 2 nd buried portion 43B is formed to the tip end surface in the 1 st direction D1 in the one end portion 20B of the 2 nd core resin portion 2B. The 3 rd buried portion 43C is formed to the tip end surface in the 1 st direction D1 in the one end portion 20C of the 3 rd core resin portion 2C. The embedded parts 43A, 43B, and 43C form the tip end surfaces of the core resin parts 2A, 2B, and 2C in the 1 st direction D1, thereby effectively preventing displacement of the core resin parts 2A, 2B, and 2C in the 2 nd direction D2 and the 3 rd direction D3.

However, the embedded portions 43A, 43B, and 43C may not be formed on the tip end surfaces in the 1 st direction D1 of the one end portions 20A, 20B, and 20C of the core resin portions 2A, 2B, and 2C. In other words, each embedded portion 43A, 43B, 43C may be formed near the tip end surface in the 1 st direction D1 of one end portion 20A, 20B, 20C of each core resin portion 2A, 2B, 2C.

As shown in fig. 6, in a state before the connector 1 is formed, the 1 st groove 21A for disposing the 1 st buried portion 43A is formed in the 1 st core resin portion 2A. The 1 st groove 21A is formed in the side end surface 202 of the 1 st core resin portion 2A in the 2 nd direction D2 and the side end surface 202 of the 3 rd direction D3. In addition, in a state before the connector 1 is formed, the 2 nd groove 21B for arranging the 2 nd buried portion 43B is formed in the 2 nd core resin portion 2B. The 2 nd groove 21B is formed in the side end surface 202 of the 2 nd core resin part 2B in the 2 nd direction D2 and the side end surface 202 of the 3 rd direction D3. In addition, in a state before the connector 1 is formed, a 3 rd groove 21C for arranging the 3 rd buried portion 43C is formed in the 3 rd core resin portion 2C. The 3 rd grooves 21C are formed in the side end surfaces 202 of the 3 rd core resin portion 2C on both sides in the 2 nd direction D2. The 1 st to 3 rd grooves 21A, 21B, 21C are formed from the respective intermediate portions embedded in the outer resin portion 4 among the 1 st to 3 rd core resin portions 2A, 2B, 2C to the respective one end portions 20A, 20B, 20C of the 1 st to 3 rd core resin portions 2A, 2B, 2C.

The 1 st to 3 rd terminals 3A, 3B and 3C are made of a metal material having excellent conductivity. The 1 st to 3 rd core resin portions 2A, 2B, 2C and the outer resin portion 4 are made of thermoplastic resin having excellent moldability such as injection molding.

(production method)

In manufacturing the connector 1, the 1 st to 3 rd core resin portions 2A, 2B, and 2C, in which the 1 st to 3 rd terminals 3A, 3B, and 3C are respectively arranged, are molded by insert molding. Next, the 1 st to 3 rd core resin portions 2A, 2B, 2C are arranged in a combined state in a molding die for molding the connector 1. At this time, the 1 st to 3 rd grooves 21A, 21B, 21C of the 1 st to 3 rd core resin portions 2A, 2B, 2C are covered by a part of the molding die.

Next, a resin material for molding the outer resin portion 4 is injected into the mold. At this time, the resin material for molding the outer resin portion 4 flows into the 1 st to 3 rd grooves 21A, 21B, 21C and fills the 1 st to 3 rd grooves 21A, 21B, 21C. In the process of curing the resin material for molding the outer resin portion 4, the molded connector 1 is taken out from the molding die.

Next, when the resin material for molding the main body portion of the outer resin portion 4 is cooled and contracted outside the molding die, the first ends 20A, 20B, and 20C of the 1 st to 3 rd core resin portions 2A, 2B, and 2C are urged in directions to move away from each other in the 2 nd direction D2 and the 3 rd direction D3. The main body portion of the outer resin portion 4 is a portion of the outer resin portion 4 constituting the connector base portion 11 and the connector protrusion portion 12, excluding the 1 st to 3 rd sandwiching portions 42A, 42B, and 42C.

At this time, the volume of the resin material filled in the 1 st to 3 rd grooves 21A, 21B, and 21C and the cross-sectional area orthogonal to the flow of the resin material are smaller than the volume of the resin material constituting the main body portion of the outer resin portion 4 and the cross-sectional area orthogonal to the flow of the resin material, and therefore, it is considered that the resin material is cured earlier than the resin material constituting the main body portion of the outer resin portion 4. Therefore, when the resin material constituting the main body portion of the outer resin section 4 shrinks, the first end portions 20A, 20B, and 20C of the 1 st to 3 rd core resin sections 2A, 2B, and 2C are supported so as not to open in the 2 nd direction D2 and the 3 rd direction D3 to the 1 st to 3 rd clamping portions 42A, 42B, and 42C formed in the 1 st to 3 rd grooves 21A, 21B, and 21C. Thus, the connector 1 can be manufactured in which the resin material constituting the outer resin portion 4 is cured and the first ends 20A, 20B, and 20C of the 1 st to 3 rd core resin portions 2A, 2B, and 2C are prevented from being displaced.

(Effect)

In the connector 1 of this embodiment, when the one end portions 20A, 20B, and 20C of the three core resin portions 2A, 2B, and 2C are arranged outside the outer resin portion 4 so as to overlap each other, it is conceivable that the one end portions 20A, 20B, and 20C of the three core resin portions 2A, 2B, and 2C are not separated from each other.

Specifically, the 1 st buried portion 43A and the 2 nd buried portion 43B of the 1 st clamping portion 42A of the outer resin part 4 clamp a part of the one end 20A of the 1 st core resin part 2A and a part of the one end 20B of the 2 nd core resin part 2B facing each other in the 2 nd direction D2 from both sides in the 2 nd direction D2. Further, the 1 st buried portion 43A and the 3 rd buried portion 43C of the 2 nd clamping portion 42B of the outer resin part 4 clamp a part of the one end portion 20A of the 1 st core resin part 2A and a part of the one end portion 20C of the 3 rd core resin part 2C facing each other in the 3 rd direction D3 from both sides in the 3 rd direction D3. Further, the 2 nd buried portion 43B and the 3 rd buried portion 43C of the 3 rd clamping portion 42C of the outer resin part 4 clamp a part of the one end portion 20B of the 2 nd core resin part 2B and a part of the one end portion 20C of the 3 rd core resin part 2C facing each other in the 3 rd direction D3 from both sides in the 3 rd direction D3.

With these configurations, even when stress at the time of shrinkage of the resin material constituting the main body portion of the outer resin part 4 is applied to the one end portions 20A, 20B, and 20C of the core resin parts 2A, 2B, and 2C by cooling outside the molding die when the core resin parts 2A, 2B, and 2C are fitted to each other and the outer resin part 4 is molded, the one end portion 20A of the 1 st core resin part 2A and the one end portion 20B of the 2 nd core resin part 2B can be prevented from being separated from each other in the 2 nd direction D2. In this case, the one end portion 20A of the 1 st core resin part 2A and the one end portion 20C of the 3 rd core resin part 2C can be prevented from being separated from each other in the 3 rd direction D3, and the one end portion 20B of the 2 nd core resin part 2B and the one end portion 20C of the 3 rd core resin part 2C can be prevented from being separated from each other in the 3 rd direction D3. In particular, after the molded connector 1 is removed from the molding die, the positional relationship of the one end portions 20A, 20B, and 20C of the 1 st to 3 rd core resin portions 2A, 2B, and 2C in the 2 nd direction D2 and the 3 rd direction D3 can be maintained.

As described above, in the connector 1 of the present embodiment, when the core resin portions 2A, 2B, and 2C are fitted and the outer resin portion 4 is molded, the one end portions 20A, 20B, and 20C of the core resin portions 2A, 2B, and 2C disposed outside the outer resin portion 4 can be separated from each other, and thus the positions of the one end portions 31A, 31B, and 31C of the terminals 3A, 3B, and 3C can be prevented from being shifted.

Therefore, according to the connector 1 of the present embodiment, even when the one end portions 20A, 20B, and 20C of the three core resin portions 2A, 2B, and 2C are arranged outside the outer resin portion 4 so as to overlap each other, it is possible to prevent the positions of the one end portions 31A, 31B, and 31C of the terminals 3A, 3B, and 3C protruding from the one end portions 20A, 20B, and 20C of the core resin portions 2A, 2B, and 2C from being shifted.

< embodiment 2>

As shown in fig. 8, this embodiment shows a connector 1 having two core resin portions, a 1 st core resin portion 2A and a 2 nd core resin portion 2B. The connector 1 of the present embodiment includes a plurality of 1 st terminals 3A, a 1 st core resin portion 2A, a plurality of 2 nd terminals 3B, a 2 nd core resin portion 2B, and an outer side resin portion 4. The 1 st core resin portion 2A covers the intermediate portions 33 of the 1 st terminals 3A except for both end portions 31A, 32A. The 2 nd core resin portion 2B covers the intermediate portions 33 of the plurality of 2 nd terminals 3B except for both end portions 31B, 32B. The outer resin portion 4 partially covers the 1 st core resin portion 2A and the 2 nd core resin portion 2B in a state of being overlapped with each other.

The one end portions 31A of the plurality of 1 st terminals 3A and the one end portions 31B of the plurality of 2 nd terminals 3B are arranged parallel to each other along the 1 st direction D1. One end 20A of the 1 st core resin part 2A from which the one end 31A of the 1 st terminals 3A protrudes and one end 20B of the 2 nd core resin part 2B from which the one end 31B of the 2 nd terminals 3B protrudes are disposed outside the outer resin part 4 so as to face each other on a boundary surface 201 in the 2 nd direction D2 orthogonal to the 1 st direction D1.

As shown in fig. 8, a clamping portion 42D is formed in the outer resin portion 4, and the clamping portion 42D clamps a part of the one end portion 20A of the 1 st core resin portion 2A and a part of the one end portion 20B of the 2 nd core resin portion 2B together. The clamping portions 42D are disposed at both ends of the 3 rd direction D3 orthogonal to the 1 st direction D1 and the 2 nd direction D2, of the one end 20A of the 1 st core resin part 2A and the one end 20B of the 2 nd core resin part 2B, respectively.

Each of the clamping portions 42D has: a 1 st embedded portion 43A partially embedded in the one end portion 20A of the 1 st core resin portion 2A; and a 2 nd buried portion 43B partially buried in the one end portion 20B of the 2 nd core resin portion 2B. The 1 st embedded portion 43A extends toward the tip end side of the 1 st direction D1 of the outer resin portion 4 and is partially embedded at a position other than the boundary surface 201 between the one end portion 20A of the 1 st core resin portion 2A and the one end portion 20B of the 2 nd core resin portion 2B. The 2 nd buried portion 43B extends toward the tip end side of the 1 st direction D1 of the outer resin portion 4 and is partially buried at a position other than the boundary surface 201 between the one end portion 20A of the 1 st core resin portion 2A and the one end portion 20B of the 2 nd core resin portion 2B.

The clamping portion 42D of this embodiment has the 1 st buried portion 43A and the 2 nd buried portion 43B, similarly to the 1 st clamping portion 42A of embodiment 1. The groove 21D of the present embodiment in which the clamping portion 42D is disposed has the same configuration as the grooves 21A and 21B of embodiment 1. The 1 st and 2 nd core resin portions 2A and 2B and the 1 st and 2 nd terminals 3A and 3B of the present embodiment have the same configurations as the 1 st and 2 nd core resin portions 2A and 2B and the 1 st and 2 nd terminals 3A and 3B of embodiment 1.

In the connector 1 of the present embodiment, when the 1 st and 2 nd core resin portions 2A and 2B are fitted to mold the outer resin portion 4, the one end portions 20A and 20B of the 1 st and 2 nd core resin portions 2A and 2B disposed outside the outer resin portion 4 can be separated from each other, and the positions of the one end portions 31A and 31B of the 1 st and 2 nd terminals 3A and 3B can be prevented from being displaced.

Therefore, according to the connector 1 of the present embodiment, even when the one end portions 20A and 20B of the two core resin portions 2A and 2B are arranged outside the outer resin portion 4 so as to overlap each other, it is possible to prevent the positions of the one end portions 31A and 31B of the terminals 3A and 3B protruding from the one end portions 20A and 20B of the core resin portions 2A and 2B from being deviated.

Other structures, operational effects, and the like in the connector 1 of the present embodiment are the same as those in embodiment 1. In this embodiment, the same reference numerals as those in embodiment 1 denote the same components as those in embodiment 1.

The present invention is not limited to the embodiments, and various embodiments can be further configured without departing from the scope of the invention. The present invention includes various modifications, modifications within an equivalent range, and the like.
