As shown in fig. 1 to 3, a connector 100 for signal lines of the present utility model includes a female housing 10 soldered on a circuit board, wherein a slot 11 is formed in the female housing 10;

and a signal pin 20 passing through the parent seat, wherein one end of the signal pin 20 is positioned in the slot 11, and the extending direction of the signal pin 20 positioned at one end of the slot 11 is consistent with the opening direction of the slot 11;

the rubber ring 30 is arranged in the slot 11, the rubber ring 30 is positioned at the bottom of the clamping groove 12, and the rubber ring 30 is attached to the inner wall of the female seat body 10;

and an auxiliary member 40 fastened with the parent seat, wherein a through hole 41 is formed in the auxiliary member 40, and the auxiliary member 40 is attached to the inner wall of the parent seat and is abutted against the rubber ring 30.

In implementation, the connector 100 is used for linking a signal harness connector and a circuit board in the automotive field, the female base 10 is made of nylon plastic, the wire pins are made of conductive metal materials, the number of the signal pins 20 is multiple, and the signal pins 20 are fixedly connected with the female base 10. In use, one end of the signal pin 20 extending out of the female housing 10 is soldered to a solder joint of a circuit board.

In practice, the auxiliary member 40 fastened to the female housing 10 is provided, on the one hand, to facilitate the installation of the rubber ring 30. On the other hand, the spring-out of the rubber ring 30 is restricted and the deformation direction of the rubber ring 30 is restricted.

In this way, the female socket body 10 is welded on the circuit board, the plug which needs to be connected with the plug connector 100 is inserted into the slot 11 and is contacted with one end of the signal pin 20 positioned in the slot 11 to realize the connection of an electric path, the plug is inserted into the slot 11, the rubber ring 30 is arranged between the plug and the female socket body 10, the rubber ring 30 is extruded to generate elastic force for generating reaction when the plug is inserted, and the inner side wall and the outer side wall of the rubber ring 30 are tightly attached with the female socket body 10 and the inserted plug under the action of self elastic force to realize sealing, so that the waterproof effect is obtained.

Further, the female housing 10 is provided with a slot 12, and the auxiliary member 40 is provided with a recess 42.

In practice, the plug inserted into the slot 12 is also provided with a buckle, which is put away by avoiding the notch 42 and is engaged with the slot 12, so as to prevent the plug from falling off from the plug connector 100 in real time.

Further, the rubber ring 30 has a corrugated shape toward the outer surface of the inner wall of the female housing 10 and the inner surface thereof.

In this way, the rubber ring 30 having a corrugated surface achieves a labyrinth seal between the plugs inserted into the slots 11.
