Detailed Description

As shown in fig. 1-3, the connection line connector 1 of the present invention is composed of a male connector 2, a female connector 3 and a connection line.

1. Male joint 2

Is formed by plastic through one-time injection molding. The front end face (when the front end face is spliced with the female connector 3, the direction of connecting with the female connector 3 is front, and the direction of keeping away from the female connector 3 is back; similarly, for the female connector 3, the direction of connecting with the male connector 2 is front, and the direction of keeping away from the male connector 2 is back, and the same below) is provided with a plurality of contact pins 21, and each contact pin 21 is connected with one lead 7 which is arranged in the male connector 2.
