Detailed Description

Embodiment 1, refer to fig. 1-4, a cylindrical contact pin socket structure, including contact pin 1 and socket 2, be provided with first connecting seat 11 on the contact pin 1, be provided with second connecting seat 21 on the socket 2, be provided with the slot 22 that runs through socket 2 and second connecting seat 21 on the socket 2, contact pin 1 end is provided with the guide arm that opens and shuts 12, is provided with conductive spring 3 in the slot 22, contact pin 1 and guide arm that opens and shuts 12 slip are pegged graft in slot 22, contact pin 1 passes through conductive spring 3 and is connected with socket 2 electricity.

In this embodiment, the pin 1 is electrically connected with the upper component a through the first connecting seat 11, the socket 2 is electrically connected with the lower component B through the second connecting seat 21, the upper and lower components may be commonly used such as copper bars or PCB boards, when the upper and lower components are separated, the opening and closing guide rod 12 disposed at the tail end of the pin 1 is still inserted into the slot 22 of the socket 2, when the upper and lower components are closed, the opening and closing guide rod 12 continues to be downward and makes the pin 1 insert into the slot 22 of the socket 2, so that the pin 1 contacts and extrudes the conductive spring 3 in the slot 22, and under the action of the conductive spring 3, both the pin 1 and the socket 2 are tightly attached to the conductive spring 3, thereby realizing stable connection and being suitable for large current transmission. Meanwhile, as the contact pin 1 is connected with the socket 2 through the conductive spring 3, a certain buffer movement space exists between the contact pin 1 and the socket 2, and damage to the upper and lower members due to rigid impact generated to the upper and lower members due to opening and closing errors of the upper and lower members can be avoided.

Wherein, a plurality of grooves 23 are arranged on the inner side of the slot 22 of the socket 2, the conductive spring 3 is annular, and at least one annular conductive spring 3 is arranged in each groove 23. By providing a plurality of conductive springs 3 in the insertion grooves 22 of the socket 2, the contact areas of the pins 1 and the socket 2 with the conductive springs 3 can be increased, thereby reducing the resistance value of the connection between the pins 1 and the socket 2. The more the number of the conductive springs 3 is, the more the number of turns of the conductive springs 3 is, the larger the contact areas of the pins 1 and the sockets 2 with the conductive springs 3 are, the smaller the resistance value of the connection between the pins 1 and the sockets 2 is, and the larger current can be transmitted. The number of the grooves 23 in the inserting groove 2 can be adjusted according to the actual use requirement, and the number of the conductive springs 3 and the number of turns of each conductive spring 3 are adjusted to adapt to the transmission of large current. In addition, in order to avoid loosening of connection between the upper and lower members and the contact pin 1 and the socket 2 caused by vibration in the opening and closing process, the first connecting seat 11 and the second connecting seat 21 are both provided with floating self-locking nuts fixedly connected with the upper and lower opening and closing members.

In a further preferred embodiment, a plurality of heat dissipation fins 24 are arranged on the outer side of the socket 2, and by the heat dissipation fins 24 arranged on the outer side of the socket 2, a good heat dissipation effect can be achieved when the contact pin 1 is connected with the socket 2, so that the connection stability of the contact pin 1 and the socket 2 is improved.

Further, in order to enable a certain buffer movement space between the opening and closing guide rod 12 and the slot 22 in the opening and closing process of the upper and lower members, the diameter of the opening and closing guide rod 12 is smaller than that of the contact pin 1, and an inclined transition part 13 is arranged between the opening and closing guide rod 12 and the contact pin 1, so that the contact pin 1 can be conveniently inserted into the slot 22.

Of course, the above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, so that all equivalent modifications made in the principles of the present utility model are included in the scope of the present utility model.
