[0018] In the figure: 1, connecting ring; 11, bare wire connecting plate; 12, wire harness connecting plate; 13, slot; 14, front wire pressing side plate; 141, cutting groove; 15, rear wire pressing side plate; 151, pressing teeth; 152, stamping groove. Specific implementation method:

[0019] Example: See Figures 1 to 4 As shown, a high-strength crimping terminal for cables comprises a circular ring 1, a long bare wire connection plate 11 is formed at the rear end of the ring 1, a strip-shaped wire harness connection plate 12 is formed at the rear end of the bare wire connection plate 11, front wire pressing side plates 14 with inclined plates staggered upward and downward are bent on both sides of the bare wire connection plate 11, and a slot 13 extending to the bare wire connection plate 11 is formed at the rear end of the inner circle of the ring 1;

[0020] Both sides of the wiring harness connecting plate 12 are bent to form arc-shaped rear wire pressing edge plates 15 facing upward.

[0021] The rear end of the slot 13 is located between the front ends of the front wire pressing edge plates 14 on both sides of the bare wire connecting plate 11 .

[0022] The two sides of the slot 13 are parallel to the two sides of the bare wire connecting plate 11 respectively, and the slot width of the slot 13 is not greater than 1 / 3 of the width of the bare wire connecting plate 11. If the slot width of the slot 13 is too large, the connection strength between the connecting ring 1 and the bare wire connecting plate 11 will be affected.

[0023] The width of the bare wire connecting plate 11 is smaller than the diameter of the outer ring of the electric ring 1 and smaller than the width of the harness connecting plate 12. The length of the bare wire connecting plate 11 is larger than that of the harness connecting plate 12. The crimping terminal is narrow in the middle and wide at both ends.

[0024] A plurality of transverse strip-shaped grooves 141 are formed on the front wire-pressing side plates 14 on both sides of the bare wire connecting plate 11, and the grooves 141 are linearly and longitudinally evenly distributed on the front wire-pressing side plates 14; the existence of the grooves 141 is conducive to the deformation of the front wire-pressing side plates 14 during crimping, so that the front wire-pressing side plates 14 can cooperate with the bare wire connecting plate 11 to effectively clamp the bare wire at the end of the cable.

[0025] A plurality of triangular stamping grooves 152 are formed on the rear crimping edge plates 15 on both sides of the wiring harness connecting plate 12, and triangular pressing teeth 151 are bent and formed on the upper sides of the stamping grooves 152, and the pressing teeth 151 are distributed on the inner surface of the rear crimping edge plates 15; the structure of the pressing teeth 151 and the stamping grooves 152 can be integrally formed by stamping, and the structure of the pressing teeth 151 is obtained by bending the material of the stamping grooves 152; the pressing teeth 151 can be pressed and buckled on the insulating outer layer of the cable to strengthen the connection strength between the rear crimping edge plates 15 and the cable.

[0026] There are certain requirements for the width of the bare wire connecting plate 11. The width of the front wire pressing edge plate 14 on the bare wire connecting plate 11 needs to be greater than half of the width of the bare wire connecting plate 11, otherwise the bare wire connecting plate 11 cannot be used to clamp the cable.

[0027] Working principle: The utility model is a high-strength crimping terminal for cables. The technical point of the high-strength crimping terminal is located at the bare wire connecting plate 11. The bare wire connecting plate 11 is provided with two groups of front crimping side plates 14 distributed upper and lower, and a slot 13 is provided between the front crimping side plates 14. The bare wire of the cable can be bent first, and then inserted into the slot 13 through the connecting ring 1. The two parts for bending the bare wire are both arranged on the front crimping side plate 14 and the slot 13, and then the insulating outer layer of the cable falls on the harness connecting plate 12. Through crimping, the rear crimping side plate 15 can hold the insulating outer layer of the cable, and the front crimping side plate 14 can hold the bare wire of the cable. Because the holding length of the bare wire part is increased, and the bare wire is bent, it can effectively prevent the problem of loosening of the cable and the crimping terminal caused by pulling the cable.

[0028] The embodiments are used to illustrate the present invention, but not to limit the present invention. Any person skilled in the art may modify the embodiments without violating the spirit and scope of the present invention, and therefore the scope of protection of the present invention shall be as set forth in the claims of the present invention.
