Problems solved by technology

[0005] For this reason, the present invention aims to solve the problem that the self-locking terminal in the prior art adopts tear forming when forming the shrapnel, and cannot meet the standard of the 24-hour salt spray test when using the process of plating first and then punching. It will be affected by the electroplating process, and the function of the shrapnel is not stable enough. Therefore, a method of cutting and squeezing is proposed to make the shrapnel project on the bottom of the slot and form a gap between the bottom of the slot. Either the process of punching first and then plating can be satisfied, so that the function of the shrapnel will not be affected by the electroplating coating and electroplating deposits

Embodiment 1

[0029] The in-line clip-shaped self-locking terminal of the present invention includes a cable connection part 2 and a wiring female terminal 3. The cable connection part 2 is clip-shaped, and the insertion direction on the cable connection part 2 is Consistent with the insertion direction of the female wiring terminal 3, fixing parts are respectively formed on both sides of the bottom surface of the cable connecting part 2, and the fixing parts are pressed to deform and fix the cable. The female wiring terminal 3 includes a slot 1. The upper part of the vertical side walls on both sides of the slot 1 is connected with two elastic planes respectively extending to the middle and used to cover the male terminal. The connection between the two elastic sheets 13 and the vertical side walls on both sides A rectangular notch is cut at the position. Corresponding to the notch, a downwardly recessed recess is formed on the elastic plane, and the recess is used to limit the movement spa...

Embodiment 2

[0031] On the basis of the in-line clip-shaped self-locking terminal described in Embodiment 1, the elastic piece 13 is formed with a locking part on the inner side of the slot 1, and the locking part is a protrusion 132, and the protrusion 132 extends smoothly along the insertion direction, and the protrusion 132 can be correspondingly snapped into the hole of the male connection terminal, so that the male connection terminal is locked. Without pressing the pressing end 131, the male connection terminal will not easily Shedding ensures stability during use.

[0032]There is a gap 14 between the projection of the elastic sheet 13 on the slot bottom 11 and the slot bottom 11, and the gap 14 is preferably 0.36 mm on one side, which can ensure that the coating is uniformly and completely plated on the elastic sheet 13. On the sheet 13, the area of ​​the slot bottom 11 will not be too small because the gap 14 is too large. As other convertible implementations, the gap 14 can also ...

Abstract

The invention discloses a direct insertion clip-shaped self-locking terminal which comprises a cable connecting part and a female wiring terminal, wherein the female wiring terminal comprises a slot, the upper parts of the vertical lateral walls at the two sides of the slot are connected with two elastic planes which respectively extend to the middle to coat a male wiring terminal, a gap is formed between the two elastic planes, an elastic flake is shaped at the bottom of the slot, one end of the elastic flake is connected with the bottom of a notch, and the other end of the elastic flake extends upwards. The contour of the elastic flake is smaller than the cavity formed at the bottom of the slot such that the elastic flake does not generate friction with surrounding incisions in the course that the elastic flake is extruded to move, the friction is not generated after an electroplated layer is plated on the elastic flake, when an electroplating process is performed, the plating layer at the surrounding incisions of the elastic flake is more uniform, therefore plating layer nonuniformity caused by small gap between the bottom of the slot in the prior art is avoided, and the problem that the standard of salt spray test for 24 hours can not be satisfied is solved.

Description

Technical field [0001] The present invention involves a wiring terminal, which is specifically a direct -inserted clip -shaped self -lock terminal. Background technique [0002] As industrial automation is getting higher and higher and industrial control requirements are becoming stricter and accurate, the amount of wiring terminals gradually increases. With the development of the electronics industry, the use of wiring terminals is more and moreAlarm device, household appliances, etc.As the degree of industrial automation becomes higher and higher and industrial requirements are becoming stricter and accurate, higher requirements have been put forward on the flexibility and reliability of the wiring terminal. [0003] Directly inserted sandwich self -lock terminals are a terminal that realizes electrical connection. It is currently widely used in the car connection of the car in the market.For example, a Chinese patent CN 102790300 A. The name is "A Direct Plug -Plugs with a low...
