One end of the cavity 31 forms a rubber core mating port 32 , and when two connectors 100 are mated, the two rubber cores 30 are symmetrically connected together through the rubber core mating port 32 . The other end of the cavity 31 forms a wire socket 33 for inserting and connecting the wire 200 .

The main elastic piece 10 and the auxiliary elastic piece 20 are inserted and fixed in the cavity 31 .

One end of the main elastic piece 10 is located in the rubber core interface 32, and the main elastic contact 11 is formed at one end of the main elastic piece 10. When the two connectors 100 are docked, the two main elastic contacts 11 of the two main elastic pieces 10 are exactly contact to achieve electrical connection. The other end of the main elastic piece 10 is located in the wire socket 33 for insertion and connection of the wire 200 . In order to assemble firmly, the side of the main elastic piece 10 forms a main latch 13 for clamping and fitting with the inner wall of the cavity 31 of the rubber core 30 , and a main barb 14 is formed on the main elastic piece 10 for being stuck in the cavity 31 of the rubber core 30 , to prevent the main elastic piece 10 from falling off from the rubber core 30 and ensure the stability of the electrical connection. Furthermore, the middle part of the main elastic piece 10 forms a folded piece 12 , and when the wire 200 is inserted, the end of the wire 200 abuts against the folded piece 12 , which acts as a limiter and ensures the electrical connection of the wire 200 .

A secondary elastic contact 21 is formed on the secondary elastic piece 20 to correspond to the other end of the main elastic piece 10. An elastic clamp M is formed between the secondary elastic contact 21 and the main elastic piece 10.
