Protective cover, the female terminal includes a hard plastic female socket and a female terminal foot arranged on the hard plastic female socket, and a female fireproof inner sleeve is provided between the female terminal foot and the hard plastic female socket, so The outer surface of the hard plastic female socket is provided with a soft plastic female protective cover.

As an improvement of the utility model, the public fireproof inner sleeve is a fireproof PC sleeve.

As an improvement of the utility model, the female fireproof inner sleeve is a fireproof PC sleeve.

As an improvement of the utility model, a waterproof ring is provided on the mating surface of the hard plastic male socket and the hard plastic female socket. Effectively improve the waterproof and dustproof effect.

As an improvement of the utility model, the soft plastic male protective cover is provided with anti-slip protrusions, which is convenient to use.

As an improvement of the utility model, the hard plastic female socket is provided with an external thread for connecting with the screw casing. Through the external thread, the screw sleeve can be sleeved on the male terminal, which improves the protection effect and prolongs the service life.

As an improvement of the utility model, a waterproof ring is provided at one end of the external thread near the soft plastic female protective sleeve. Further improve the waterproof and dustproof performance.

The beneficial effects of the utility model are as follows: the utility model has a reasonable and ingenious structural design. First, the male and female end pins are riveted with the electric wires, and then the corresponding male and female fireproof inner sleeves are put on. Injection molding is carried out to form a hard plastic male seat and a hard plastic female seat, and then soft plastic is used for secondary injection molding to form a soft plastic male protective cover and a soft plastic female protective cover, so as to realize a structure with a hard inside and a soft outside. The hard structure effectively improves the stability of the connection between the terminal pin and the wire, which is not easy to loosen, the fit is tighter, and the reliability is high, while the outer soft structure effectively protects the wire and avoids the occurrence of bad phenomena such as wire bifurcation and breakage, which not only guarantees The quality of the product is high, and it has a good waterproof and dustproof effect, and has a wide range of applications, especially for applications with a voltage range of 24-230V.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
