Referring to FIGS. 1-8 , the present application provides a connector 100 , including: a plurality of connectors 9 , a plurality of wires 8 , a first channel shell 2 , a second channel shell 3 , and a plurality of transmission members 1 . The connecting member 9 is, for example, a coil spring or an inclined spring.

The first channel shell 2 and the second channel shell 3 are both made of insulating material, such as plastic material, silicone material, or ceramic material. The first channel shell 2 and the second channel shell 3 are butted together to form a connector for insertion. 9. The connecting channel 4 is, for example, an axial through-hole-shaped channel. In the extending direction of the connecting channel 4, a plurality of spaced apart grooves 41 are formed on the connecting channel 4. Each of the connecting channels 4 is The compartment 41 is used to accommodate one of the connecting pieces 9 . Each compartment 41 may have the same shape and size.

A part of each transmission member 1 is embedded in the first channel shell 2 or the second channel shell 3, and a part of each transmission member 1 is exposed from a compartment 41 and is used to electrically connect corresponding compartments. A part of each transmission member 1 of the connecting member 9 in the groove 41 is exposed from the first channel shell 2 or the outer wall of the second channel shell 3 and is used to electrically connect at least one wire 8 . For example, the transmission member 1 is located in the first channel shell 2, and a part of the transmission member 1 is exposed from the inner wall of the first channel shell 2, and is electrically connected to the connector 9 located inside the compartment 41 in the form of contact. Another part is exposed from the outer wall of the first channel shell 2 and is used to weld the wire 8. The part of the transmission member 1 exposed from the first channel shell 2 can be flush with the outer wall of the first channel shell 2, or it can be from the first channel. The outer wall of shell 2 is convex. Accommodating the transmission member 1 in the first channel shell 2 can reduce the space occupied by the transmission member 1 on the connector 100, thereby reducing the volume of the connector 100, improving the comfort of the connector 100 when implanted in the patient's body, and When the number of connectors 9 on the connector 100 increases, the compartments 41 corresponding to the connectors 9 are separated from each other, and multiple compartments 41 are independently opened. Therefore, the tolerances of the multiple compartments 41 will not accumulate. That is, the overall assembly tolerance after multiple connectors 9 are installed on the connector 100 will not increase due to an increase in the number of connectors 9, thereby improving reliability.

Preferably, in the extension direction of the connecting channel 4, the transmission members 1 are alternately distributed on the first channel shell 2 and the second channel shell 3, that is, the transmission members 1 located in the first channel shell 2 and the transmission members 1 located in the first channel shell 2 The transmission parts 1 in the second channel shell 3 are staggered along the projection positions formed in the radial direction of the connecting channel 4 .
