Technical Field

The present disclosure relates to a female terminal.

Background

Patent document 1 discloses a female terminal fitting including a main body portion, an elastic contact piece, and an excessive deflection restricting plate. The female terminal fitting is fitted to the male terminal fitting. An anode piece is formed at the tip of the male terminal fitting.

The main body is in the shape of a square tube that opens in the front-rear direction. The elastic contact piece is arranged on the bottom plate side in the main body part. The elastic contact piece is formed by folding back a tongue piece extending forward from the front end edge of the bottom plate into the main body. The anode piece of the male terminal fitting is inserted into the main body from an opening in the front of the main body. When the anode piece is inserted, the elastic contact piece is in contact with the anode piece through the contact point portion. Thereby, the elastic contact piece is elastically deformed toward the bottom plate side.

The excessive deflection limiting plate is formed by cutting out the bottom plate. The excessive deflection limiting plate is located on the back side of the contact point portion in the elastic contact piece. The excessive deflection of the elastic contact piece toward the bottom plate side is restricted by providing an excessive deflection restricting plate.

Disclosure of Invention

Problems to be solved by the invention

When vibration occurs in a state where the male terminal fitting is fitted to the female terminal fitting, the anode piece presses the elastic contact piece toward the bottom plate side. The elastic contact piece can be displaced between the lower surface of the elastic contact piece and the excessive deflection limiting plate, and therefore the anode piece can be shaken between them.

Means for solving the problems

The female terminal of the present disclosure is a female terminal to be fitted to a male terminal, and includes: a bottom wall, an elastic contact piece and a shake suppression portion, wherein the elastic contact piece extends from the bottom wall in a cantilever shape and elastically contacts with the male terminal by displacing towards the bottom wall side, and the shake suppression portion can contact with the male terminal when the male terminal displaces towards the bottom wall side.

Effects of the invention

According to the present disclosure, a cathode terminal that suppresses the wobbling of the anode sheet can be provided.

Detailed Description

[ description of embodiments of the present disclosure ]

First, embodiments of the present disclosure are enumerated and described. The female terminal of the present disclosure is (1) a female terminal to be fitted to a male terminal, and includes: a bottom wall, an elastic contact piece and a sway suppression part, wherein the elastic contact piece extends out from the bottom wall in a cantilever shape and is elastically contacted with the male terminal through displacement towards the bottom wall side, and the sway suppression part can be contacted with the male terminal when the male terminal displaces towards the bottom wall side

When the male terminal is displaced toward the bottom wall side, the male terminal contacts the rattle suppression portion. This can suppress the male terminal from shifting to the bottom wall side and rattling.

(2) Preferably, a pair of the rattling suppression portions is provided, and the pair of the rattling suppression portions are disposed at an interval in a width direction orthogonal to both a fitting direction of the male terminal and a displacement direction of the elastic contact piece.

Since the pair of rattling suppression portions are arranged in the width direction with a space therebetween, when the male terminal is twisted, one of the pair of rattling suppression portions comes into contact with the male terminal. This can suppress twisting of the male terminal.

(3) Preferably, the female terminal includes an excessive deflection restricting portion that restricts excessive deflection of the elastic contact piece by contacting the elastic contact piece when the elastic contact piece is displaced toward the bottom wall side, and the play suppressing portion is provided integrally with the excessive deflection restricting portion, and the elastic contact piece includes a notch portion that prevents interference with the play suppressing portion.

When the elastic contact piece is displaced toward the lower wall side, the elastic contact piece comes into contact with the excessive deflection restricting portion. This can suppress excessive deflection of the elastic contact piece. Further, since the elastic contact piece has the notch portion, the rattle suppression portion can be prevented from interfering with the elastic contact piece, and the rattle suppression portion can be provided integrally with the excessive deflection restriction portion. For example, even when it is difficult to provide the excessive deflection restricting portion and the rattle suppressing portion at different positions due to the restriction of the size of the female terminal, both the excessive deflection restricting portion and the rattle suppressing portion can be provided at one position.

[ details of embodiments of the present disclosure ]

Specific examples of the female terminal 10 of the present disclosure will be described below with reference to the drawings. The present disclosure is not limited to these examples, but is defined by the claims, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

As shown in fig. 1, the female terminal 10 includes a body 12 and a wire connecting portion 13. As shown in fig. 4, an elastic contact piece 14 and an excessive deflection restricting portion 16 are provided inside the main body portion 12. As shown in fig. 8, the male terminal 20 fitted to the female terminal 10 includes an anode piece 22. The anode sheet 22 is a plate-like member elongated in the front-rear direction (fitting direction of the male terminal 20).

As shown in fig. 1, the main body 12 has a rectangular tube shape that is long in the front-rear direction. As shown in fig. 4, the main body 12 is open in the front-rear direction. The main body 12 includes a top wall 24 and a bottom wall 26 facing each other in the vertical direction, and a pair of side walls 28 facing each other in the lateral direction. The top wall 24 connects the upper edges of a pair of side walls 28 to each other. On the other hand, the bottom wall 26 connects the lower edges of the pair of side walls 28 to each other. A wire connecting portion 13 connected to a wire (not shown) is provided behind the main body 12. The wire connecting portion 13 is continuous rearward from the bottom wall 26 of the main body 12.

As shown in fig. 4, the elastic contact piece 14 is folded back from the front end of the bottom wall 26 of the main body 12 and extends in a cantilever manner. The elastic contact piece 14 is elastically displaceable downward (toward the bottom wall 26). As shown in fig. 5, the elastic contact piece 14 is provided with a pair of notches 14A. The pair of notches 14A are formed in an L-shape from the rear portion of the both side edges of the elastic contact piece 14 to the rear end edge. That is, the notch 14A has a shape obtained by cutting out both corners of the rear end of the elastic contact piece 14. As shown in fig. 3 and 4, the elastic contact piece 14 is provided with a contact point portion 14B. The contact point portion 14B protrudes upward from the upper surface of the elastic contact piece 14.

As shown in fig. 3, the top wall 24 is provided with a pair of bead portions 24A. The pair of bead portions 24A are arranged with a space in the left-right direction (width direction orthogonal to both the fitting direction of the male terminal 20 and the displacement direction of the elastic contact piece 14). The bead portion 24A protrudes downward from the lower surface of the top wall 24. As shown in fig. 4, the bead portion 24A is long in the front-rear direction.

As shown in fig. 6 and 7, the anode piece 22 of the male terminal 20 is inserted into the body 12 from an opening in the front of the body 12. As shown in fig. 8, when the male terminal 20 is fitted to the female terminal 10, the contact point portion 14B of the elastic contact piece 14 elastically contacts the anode piece 22 from below. Thereby, the anode sheet 22 is pressed upward to contact the bead portion 24A, and the male terminal 20 is electrically connected to the female terminal 10.

As shown in fig. 2 and 4, the excessive deflection restricting portion 16 is formed by cutting a part of the bottom wall 26 upward. As shown in fig. 5, the excessive deflection restricting portions 16 are provided in a pair on the left and right. A part of the pair of excessive deflection restricting portions 16 faces the lower surface of the elastic contact piece 14. Thus, for example, when the male terminal 20 is fitted to the female terminal 10, the male terminal 20 is inserted into the body 12 in an inclined state. At this time, the anode piece 22 strongly contacts the elastic contact piece 14, and the elastic contact piece 14 is largely displaced downward. When the elastic contact piece 14 is displaced downward, the lower surface of the elastic contact piece 14 comes into contact with the pair of excessive deflection restricting portions 16, and the elastic contact piece 14 is prevented from further displacing downward. Therefore, the elastic contact piece 14 can be suppressed from being excessively deflected.

As shown in fig. 4, the excessive deflection restricting portion 16 is provided with a rattle suppressing portion 18. As shown in fig. 5, the sway suppression section 18 is provided in a pair of left and right. As shown in fig. 4, the pair of sway suppression portions 18 is provided integrally with the pair of excessive deflection restricting portions 16. The sway suppression part 18 protrudes upward from the upper end of the excessive deflection limiting part 16. As shown in fig. 5, a part of the backlash suppressing portion 18 is located inside the notch portion 14A of the elastic contact piece 14 (within the range of the broken line R in fig. 5).

As shown in fig. 8 and 9, the rattle suppression portion 18 faces the lower surface of the anode sheet 22 in a state where the male terminal 20 and the female terminal 10 are fitted to each other. For example, when the male terminal 20 swings in the vertical direction due to vibration or the like, the anode piece 22 presses the elastic contact piece 14 downward and contacts the sway suppression section 18. This prevents the anode sheet 22 from being displaced further downward. Therefore, the vibration width of the anode sheet 22 in the vertical direction is smaller than that in the case where the fluctuation suppression section 18 is not provided, and fluctuation of the anode sheet 22 can be suppressed. By suppressing the wobbling of the anode piece 22, the anode piece 22 slides on the elastic contact piece 14 in the vibration environment, and the abrasion of the elastic contact piece 14 can be suppressed. Therefore, the connection reliability between the male terminal 20 and the female terminal 10 can be ensured.

By providing the notch portion 14A in the elastic contact piece 14, the rattle suppression portion 18 can be provided integrally with the excessive deflection restricting portion 16 while preventing the rattle suppression portion 18 from interfering with the elastic contact piece 14. For example, when the elastic contact piece 14 is configured without the notch 14A, the play suppressing portion needs to be provided at a position where it does not interfere with the elastic contact piece. That is, the wobbling-prevention portion needs to be provided outside the range of the broken line R shown in fig. 5 (for example, on both sides or behind the elastic contact piece). In this case, the sway suppression section and the excessive deflection restriction section need to be provided at different positions. Therefore, by providing the notch portion 14A, even when it is difficult to provide the excessive deflection restricting portion 16 and the rattle suppressing portion 18 at different positions due to, for example, the dimensional restriction of the female terminal 10, both the excessive deflection restricting portion 16 and the rattle suppressing portion 18 can be provided at one position.

As shown in fig. 9, when the male terminal 20 is twisted in the rotation direction indicated by the arrow D, the anode piece 22 contacts the left sway suppression part 18 of the pair of sway suppression parts 18. Thereby, the rotation of the male terminal 20 is prevented. When the male terminal 20 is twisted in the direction opposite to the rotation direction indicated by the arrow D, the anode piece 22 contacts the right wobble suppression portion 18 of the pair of wobble suppression portions 18. Thereby, the rotation of the male terminal 20 is prevented. As described above, the pair of play suppressing portions 18 can suppress twisting of the male terminal 20.
