Example 1

The tip and harness connector shown in fig. 1 to 3 includes a terminal body 10 and a wire crimped to the terminal body 10, the wire including a conductive portion 80 and an insulating portion 90, the conductive portion 80 being a plurality of copper wires included in the insulating portion 90, and the main purpose of the conductive portion being to conduct electricity through a terminal after being connected to the terminal body 10. The terminals are clamped in the accommodating cavities of the connectors 20 to form the male connector 20.

Specifically, the terminal body 10 is connected to one end of the wire, i.e., the end is provided with a first crimp cavity 40 and a second crimp cavity 50, and further, a plurality of hemispherical protrusions 30 are provided at the top and bottom of the first crimp cavity 40 and the second crimp cavity 50.

An opening 60 is provided between the first crimp cavity 40 and the second crimp cavity 50, the first crimp cavity 40 is used for connecting the conductive portion 80 of the wire, and the second crimp cavity 50 is used for connecting the insulating portion 90 of the wire, wherein the radius of the first crimp cavity 40 is smaller than that of the second crimp cavity 50, and when the wire is inserted into the first crimp cavity 40 and the second crimp cavity 50, the two cavities are recessed by a tool, so that the wire is fixed on the terminal body 10.

Specifically, after the first compression joint cavity 40 and the second compression joint cavity 50 are concave, the protrusion 30 presses the wire harness downwards so that a part of the wire contacting the protrusion 30 is concave and deformed, the pressure of the cavity walls of the first compression joint cavity 40 and the second compression joint cavity 50 on the wire harness is increased, and the friction force is further increased to prevent the wire from falling off due to the fact that the wire is pulled backwards by external force.

After compression, the wire portion and the insulating portion 90 form a wave-like structure, thereby providing the protrusion 30 with a backstop effect.

Preferably, in the initial state, both the first crimp cavity 40 and the second crimp cavity 50 are cylindrical in configuration and, in use, are flattened up and down into cavities of oval configuration.

In particular, the protrusions 30 on the top wall and the bottom need to be staggered, that is, also have a wavy structure, so that the wires can be better prevented from falling off.

Example 2

As shown in fig. 4, the difference from embodiment 1 is that the protrusion 30 has a wedge-shaped structure, and the rear side of the protrusion 30, i.e., the side near the wire connection point, is provided with a slope 70 to facilitate the insertion of the wire. Compared with the hemispherical structure in embodiment 1, the other surface of the protrusion 30 of the wedge-shaped structure is a plane perpendicular to the top and bottom surfaces of the cavity, and the connection with the wire is more stable and reliable, and the retaining effect is better.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
