Detailed ways

Embodiment 1, referring to Figures 1-4, a pin connection terminal, including a male terminal 1 and a female terminal 2 that can be plugged and mated with each other, the male terminal 1 is provided with a male pin 3, and the female terminal 2 is provided with a female pin 4, the male pin 3 includes a pin body 31 and a covering part 32 arranged outside the pin body 31, the female pin 4 forms an insertion slot 41 inside, and the male pin The main body 31 of the pin 3 is mated and connected with the insertion groove 41 , and the covering part 32 is wrapped around the outer side of the female pin 4 .

In this embodiment, when the male pin 3 in the male terminal 1 is connected to the female pin 4 of the female terminal 2, the pin body 31 of the male pin 3 is inserted into the female pin 4. In the insertion groove 41, the outside of the female pin 4 is wrapped and tightly fitted by the covering part 32 of the male pin 3, thereby effectively improving the stability of the connection between the male pin 3 and the female pin 4. The cladding structure can avoid the problems of poor contact and heat caused by the reduction of the contact area when subjected to lateral force, and can avoid the problem of loose connection caused by lateral force, and improve the lateral contact of the pin connection terminal. force bearing capacity.

Specifically, the above-mentioned male terminal 1 includes a male body 11 and a male rear cover 12, the front end of the male pin 3 is plugged and fixed in the male body 11, the male rear cover 12 is connected to the rear end of the male body 11 and Wrap the rear end of the male pin 3; the female terminal 2 includes a female body 21 and a female back cover 22, the female pin 4 is fixed in the female body 21, and the female back cover 22 covers the female plug The rear end of the needle 4; the male body 11 can be plugged and fixed in the female body 21 .
