Technical Field

The present invention relates to a contact having a pressure-bonding section for pressure-bonding an electric wire, and a connector provided with the contact.

Background

Conventionally, a connector provided with a contact having a crimping portion is known. For example, patent document 1 discloses a contact having a pressure-bonding portion above a base portion and a contact portion contacting a mating contact below the base portion. In the pressure-bonding section, pressure-bonding grooves are formed in the left and right centers. The pressure-bonding groove receives the coated electric wire to cut the coating and contact the core wire. The contact portion receives the inserted male mating contact between the base portion and the mating contact. The contact has press-fitting portions press-fitted into the housing on both left and right sides of the press-fitting portion. When the contact is mounted in the housing, the press-fitting portion is press-fitted into the housing, and the contact is fixed to the housing.

Disclosure of Invention

Problems to be solved by the invention

Recent demands for miniaturization and weight reduction also relate to connectors provided with contacts of the above type. Therefore, the contact is also miniaturized and thinned, and is easily bent.

Here, in the case of the contact having the structure disclosed in patent document 1, when the contact is press-fitted into the housing, the press-fitting portion receives a reaction force from the housing, and a force in a direction of reducing the width of the press-fitting groove acts on the press-fitting portion. Therefore, if the contact is easily bent due to the influence of the miniaturization and the thinning, the press-fitting portion may not be firmly press-fitted into the housing, and the original effect may not be exhibited.

In addition, when the counterpart contact is taken in between the contact portion and the base portion, the contact portion is elastically deformed. Here, in the contact of the structure disclosed in patent document 1, the press-fitting portion is located at the left and right positions of the pressure-bonding section. Therefore, the pressure-bonding section may be affected by elastic deformation of the contact section due to insertion of the mating contact. If the contact is easily deflected due to the influence of the miniaturization and thinning, the influence on the pressure-bonding section is large, and the contact pressure with the core wire at the pressure-bonding section may fluctuate.

An object of the present invention is to provide a contact and a connector including the contact, the contact having the following structure: when the contact is mounted in the housing, the press-fitting portion is reliably pressed into the housing, and the influence of the insertion of the mating contact is suppressed from being transmitted to the pressure-bonding portion.

Means for solving the problems

The contact of the present invention for achieving the above object is characterized by comprising: a base; a pressure-bonding section extending upward from the base section and having a pressure-bonding groove in which the wire is pressed; an overhanging portion that is folded downward at an upper end of the pressure-bonding portion and extends downward, and that has a press-fitting portion that is press-fitted into the housing below the pressure-bonding groove; and a contact portion extending from a lower end of the overhang portion, receiving the inserted male mating contact between the base portion and the contact portion, and contacting the mating contact.

In the contact of the present invention, the press-fitting portion is formed below the pressure-bonding groove, that is, at a position where the pressure-bonding groove is not present. Therefore, even if a reaction force acts on the press-fitting portion, the press-fitting portion can be reliably press-fitted into the housing by the reaction force.

In the contact of the present invention, the press-fitting portion is provided between the pressure-bonding portion and the contact portion. Therefore, the influence of the deformation of the contact portion due to the insertion of the mating contact is cut off at the position of the press-fit portion, and the influence can be suppressed from being involved in the pressure-bonding portion.

Here, in the contact of the present invention, it is preferable that the pressure-bonding section has a first pressure-bonding section and a second pressure-bonding section provided at each of a front end portion and a rear end portion of the base section in the insertion direction of the counterpart contact, respectively, and the overhanging section is folded back downward at an upper end of the first pressure-bonding section and extends downward.

If the first crimping portion and the second crimping portion are provided, the crimping portion and the core wire are electrically conducted with higher reliability.

In addition, the connector according to the present invention to achieve the above object is characterized by including a housing and the contact according to any one of the aspects of the present invention, and the press-fitting portion is press-fitted into the housing.

According to the connector of the present invention, a highly reliable connector is realized.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the above invention, the following contact and connector are realized: the contact is stably supported by the housing and operates stably even if the counterpart contact is inserted.

Detailed Description

Hereinafter, embodiments of the present invention will be described.

Fig. 1 is a perspective view of a contact according to an embodiment of the present invention.

The contact 10 is formed by blanking and bending a metal flat plate. The contact 10 has a base portion 20, a crimping portion 30, an overhanging portion 40, and a contact portion 50.

The base 20 has a flat plate shape, expanding horizontally.

The pressure-bonding section 30 extends upward from the base section 20. In the pressure-bonding section 30, a pressure-bonding slit 31 for pressure-bonding the coated electric wire 90 (see fig. 5) is formed. If the coated electric wire 90 is fitted to the crimping portion 30, the coating of the coated electric wire 90 is cut off at the edges of both sides of the crimping slit 31, and the core wire inside thereof is electrically conducted to the contact 10. The pressure-bonding sections have a first pressure-bonding section 30A and a second pressure-bonding section 30B, respectively, which are provided at each of the front end and the rear end of the base 20 in the insertion direction of the mating contact 81 (see fig. 5) indicated by the arrow S. By crimping the coated electric wire 90 to both the first crimping portion 30A and the second crimping portion 30B, the reliability of conduction between the core wire and the contact 10 is improved.

In addition, the overhanging portion 40 is folded back downward at the upper end of the pressure-bonding section 30 (specifically, the upper end of the first pressure-bonding section 30A provided at the front end portion in the insertion direction indicated by the arrow S) and extends downward. The hanging portion 40 has a press-fitting portion 41 that is press-fitted into the housing. The press-fitting portions 41 are provided on both left and right sides of the suspended portion 40 at positions lower than the press-fitting grooves 31. The pressure contact slit 31 is not formed at the portion where the press-fitting portion 41 is provided, and there is no space such as the pressure contact slit 31 between the left and right press-fitting portions 41. Therefore, even if a force is applied in a direction (direction indicated by arrow F) in which the left and right press-fitting portions 41 are brought close to each other, the distance between the left and right press-fitting portions 41 is maintained. On the other hand, if a force in the direction indicated by the arrow F' is applied to the pressure-bonding section 30 in which the pressure-bonding slit 31 is formed, the pressure-bonding slit 31 is deflected inward, and the left and right edges 32 of the pressure-bonding section 30 approach each other. In the contact disclosed in patent document 1, a press-fitting portion is formed at a position indicated by an arrow F' and parallel to the pressure contact slit 31. Therefore, the pressure contact slit 31 may be bent inward, and the press-fitting portion may move in a direction away from the wall of the housing, thereby failing to sufficiently press-fit and holding the contact. On the other hand, in the case of this embodiment, there is no space such as the pressure contact gap 31 between the left and right press-fitting portions 41, and even if the press-fitting portions 41 receive a strong reaction force from the wall 61 of the housing 60, the reaction force can be received, and sufficient press-fitting can be performed.

In addition, the contact portion 50 extends in a cantilever shape from the lower end of the suspended portion 40. The contact portion 50 is interposed between the inserted male mating contact 81 and the base portion 20, and is in contact with and electrically connected to the mating contact 81.

Fig. 2 is a perspective view of a connector as an embodiment of the present invention.

Fig. 3 is a plan view of the connector shown in a perspective view in fig. 2.

Fig. 4 is an enlarged sectional view (a) taken along arrow a-a shown in fig. 3 and an enlarged sectional view (B) taken along arrow B-B shown in fig. 3.

The connector 100 shown in fig. 2 includes a housing 60 and a plurality of (13 in the case of the example shown in fig. 2) contacts 10 attached to the housing 60. The direction of arrow S shown in fig. 2 coincides with the direction of arrow S shown in fig. 1. That is, the plurality of contacts 10 are attached to the housing 60 so that the direction of the arrow S in fig. 1 coincides with the direction of the arrow S in fig. 2.

As shown in fig. 4(a), if each contact 10 is fitted into the housing 60, the press-fitting portion 41 is press-fitted into the wall 61 of the housing 60 so as to be recessed. Thereby, each contact 10 is fixed at each predetermined position in the housing 60.

In the housing 60, insertion openings 62 into which mating contacts 81 (see fig. 5) are inserted are formed at positions corresponding to the contacts 10. As shown in fig. 4(B), the insertion opening 62 is formed at a position communicating with the receiving opening 51 of the mating contact 81 between the base portion 20 and the contact portion 50 of the contact 10. In the housing 60, housing grooves 63 corresponding to the contacts 10 are formed. The end of the coated electric wire 90 is crimped by the crimping portion 30 of the contact 10, and a portion connected to the crimped end is accommodated in the accommodation groove 63 of the housing 60. However, the covered electric wire 90 is not shown in fig. 2 to 4.

Fig. 5 is a perspective view showing a cross section of the connector of the present embodiment along arrow B-B shown in fig. 3. In fig. 5, a covered electric wire 90 is also shown. However, the coated electric wire 90 shown here is not distinguished between the coating and the core wire, but is shown as an integral component. Fig. 5(B) and (C) also show perspective views of the mating connector 80 in cross section at corresponding positions.

As shown in fig. 5(a), the end of the coated electric wire 90 is crimped by the crimping portion 30 of the contact 10, and a portion connected to the crimped end is accommodated in the accommodation groove 63 of the housing 60.

Fig. 5(B) shows the mating connector 80 before fitting in the direction and posture of the connector 100.

Fig. 5(C) shows the mating connector 80 fitted to the connector 100.

The mating connector 80 includes the same number of male mating contacts 81 as the contacts 10 of the connector 100. When the mating connector 80 is fitted to the connector 100, the mating contacts 81 are inserted into the connector 100 through the insertion openings 62. Then, the inserted counterpart contact 81 is sandwiched by the contact portion 50 and the base portion 20 of the contact 10 of the connector 100, and electrically conducted with the contact 10. The contact portion 50 is elastically deflected at the time of insertion of the mating contact 81. However, the influence of the deflection of the contact portion 50 is suppressed at the portion of the suspended portion 40 where the press-fitting portion 41 is formed, and the influence on the pressure-bonding section 30 can be ignored. Therefore, stable conduction between the pressure-bonding section 30 and the core wire of the coated electric wire 90 is maintained.

In addition, although the connector 100 including 13 contacts 10 is described here, the number of the contacts 10 may be one or more.
