When the contact pin is used, the movable socket is inserted into the contact pin body 2, and the first contact 3 is contacted with the top of the contact pin body; the second contact 4 is contacted with the left side wall surface of the contact pin body; the third contact 5 is contacted with the right side wall surface of the contact pin body, so that communication is established for the flat cable; if the flat cable communication is to be disconnected, the movable jack is pulled out.

The utility model discloses the beneficial effect who gains does:

this reliable winding displacement of communication passes through the mode of plug and this body coupling of contact pin, and three point contact is realized through first contact, second contact, third contact and base contact pin to inside, has avoided inside only through single contact and base contact pin to establish the communication relation of traditional winding displacement, has easily caused the winding displacement to insert not in place down, or leads to the winding displacement contact failure because of vibrations, problem on the communication. The reliability of the flat cable communication is improved.
