Detailed Description

Example 1:

referring to fig. 1-4, a composite terminal includes a square 1 and a body 2.

The square needle 1 is made of conductive materials, and the cross section of the square needle 1 is square, namely rectangular. In this embodiment, the guideline 1 is provided with a wide portion 11 and a narrow portion 12, the size of the wide portion 11 is larger than that of the narrow portion 12, the size is specifically the cross-sectional size, and is not the length of the wide portion 11 and the narrow portion 12, and the wide portion 11 abuts against the inner wall of the accommodating cavity. Wide portion 11 stretches into to holding in the chamber 21, and wide portion 11 offsets with holding the intracavity 21 inner wall to make the square needle 1 bigger with the area of contact that holds between the chamber 21, better realization fixed effect.

2 front ends of body are used for cooperating fixedly with square needle 1, are equipped with on 2 front ends of body and hold chamber 21, hold chamber 21 and be equipped with front opening 3 and side opening 4. The front opening 3 is located at one end, namely the foremost end, of the body 2 close to the square needle 1, and in this embodiment, for better fixing effect, the clamping portion 31 is arranged on the front opening 3, and the clamping portion 31 abuts against the square needle 1. The arrangement of the clamping part 31 is adopted, so that the fixing effect of the guideline 1 is better realized. In the present embodiment, the size of the front opening 3 is larger than that of the square needle 1, so that the clamping portion 31 extends obliquely and abuts against the side surface of the square needle 1.

One end of the front opening 3 is a frame-shaped structure, and in order to increase the strength of the front opening 3, a first bending portion 32 is arranged on one side surface of the front opening 3, and the first bending portion 32 is bent to a top wall of the accommodating cavity 21 close to one end of the front opening 3. The provision of the first fold 32 provides an overlapping arrangement on the top wall of the body 2, which provides increased strength on the side of the body 2 adjacent the front opening 3.

Furthermore, a second elastic bulge 33 is arranged on the top inner wall of the accommodating cavity 21 close to one end of the front opening 3, the second elastic bulge 33 is positioned below the first bending part 32, and the second elastic bulge 33 is abutted against the upper surface of the square needle 1. The second elastic bulge 33 is provided to ensure better fixing effect between the accommodating cavity 21 and the guideline 1. The second elastic bulge 33 here forms a circular boss for the stamping.

Side opening 4 is located and holds the chamber 21 and keep away from one side of front opening 3, and side opening 4 is hollowed out and is held the elastic bulge cooperation formation on the chamber 21 through holding the chamber 21 side, and two side intercommunications have formed the side opening 4 structure promptly.

The top wall of the side opening 4 is provided with an elastic projection 41. The elastic protrusions 41 are arranged, so that the whole composite terminal forms a limiting and fixing effect in the installation process. The elastic protrusion 41 is provided with a protrusion 411. In this embodiment, the elastic projection 41 is inclined obliquely upward.

The bottom surface of the accommodating cavity 21 is provided with a first elastic bulge 22 and a hollow portion 23, in this embodiment, the number of the first elastic bulge 22 can be adjusted according to actual requirements, here, the number of the first elastic bulge 22 is two, the two first elastic bulges 22 have the same structure and are abutted against the bottom surface of the square needle 1, so as to achieve the fixing effect of the square needle 1, it is further described here that the first elastic bulge 22 forms an arch structure, and here, the first elastic bulge 22 can also be formed by stamping. The cutouts 23 are arranged partially on both sides of the first spring bead 22, i.e. one spring bead 22 corresponds to two cutouts 23. By adopting the arrangement of the hollow-out part 23, the first elastic bulge 22 is more convenient to process, and the elastic effect of the first elastic bulge 22 is better in the assembling process.

Be equipped with the welding boss 24 of bending on the side that holds chamber 21, welding boss 24 specifically is for holding the inboard bending of chamber 21 towards, and the welding boss 24 after bending is parallel with holding the chamber 21 bottom surface, and 1 upper surface of square needle offsets with

welding boss

24, and 1 lower surface of square needle offsets with first elasticity uplift 22, and what need explain, the junction and the side opening 4 intercommunication of square needle 1 and welding boss 24. After the square needle 1 and the welding boss 24 are fixed, the joint of the square needle 1 and the welding boss 24 is subjected to laser welding through a welding lens, so that the square needle 1 and the welding boss 24 are firmly fixed.

The end of the body 2 far away from the square needle 1 is provided with a connecting part 25. By adopting the arrangement of the connecting part 25, in the processing process, a connecting effect can be formed among a plurality of composite terminals through the connecting part 25, and the effect of batch processing is formed. In addition, the main body 2 is further provided with a wire portion for cooperating with a wire, and the structure of this embodiment is not described in detail herein.

Firstly, adopt this kind of structural setting, saved the steel bushing structure, reduced the waste of raw and other materials, then stretch into to holding in the chamber 21 through square needle 1, square needle 1 has formed the upper and lower fixed of vertical direction through welding boss 24 and first elastic bulge 22, after both assemble together, in the inside junction of direct welding square needle 1 and welding boss 24 of die for size precision is higher, and the simultaneous processing is more convenient.
