[0026] Example:

[0027] See also Figure 1-5 A car door handle connector includes a plastic body 1, two assemblies 2 are arranged in the plastic body 1, an outer surface of the plastic body 1 is integrally injection-molded with an overmolded plastic 3, and the overmolded plastic 3 corresponds to the two assemblies 2, and the outer surface of the plastic body 1 is covered with a silicone ring 4;

[0028] Each assembly 2 includes a wire plug 21, a wire 22 and a terminal 23. The wire plug 21 is inserted into the plastic body 1 and corresponds to the plastic overmolding 3. The wire 22 is inserted into the wire plug 21 and passes through the plastic overmolding 3. The terminal 23 is fixedly connected between the wire plug 21 and the wire 22, and the terminal 23 is located inside the plastic body 1.

[0029] In this embodiment, the two wires 22 are respectively inserted into the two wire plugs 21, and the two terminals 23 are crimped onto the two wires 22 and the two wire plugs 21 after insertion, thereby forming two assemblies 2, and then the two assemblies 2 are inserted into the plastic body 1. The encapsulated plastic 3 adopts the plastic mold secondary molding technology to encapsulate the two assemblies 2 so that the two assemblies 2 are sealed and fixed in the plastic body 1. The silicone ring 4 is sleeved on the plastic body 1. The plastic body 1 and the client's socket are plugged together to play the role of signal transmission. The silicone ring 4 makes the plugging waterproof and dustproof.

[0031] In this embodiment, after the overmolding plastic 3 is injection molded, an overmolding protrusion 6 is formed inside. The overmolding protrusion 6 is located in the overmolding groove 5 and can be stabilized on the outer surface of the plastic body 1 while ensuring a sealing effect.

[0032] Specifically, a limiting groove 9 is provided on the outer surface of the plastic body 1 , and the silicone ring 4 is located in the limiting groove 9 .

[0033] In this embodiment, the limiting groove 9 stabilizes the silicone ring 4 on the plastic body 1 after being mounted, thereby preventing the silicone ring 4 from falling off the plastic body 1 .

[0034] Specifically, the outer surface of the encapsulated plastic 3 is provided with a snap-fit protrusion 10 , and the outer surface of the encapsulated plastic 3 is provided with a notch 11 .

[0035] In this embodiment, the snap-fit protrusion 10 can be used to snap the connector into place with the client's socket, so that the connector is stabilized in the socket. The notch 11 facilitates the fixation of the entire connector, so that the connector is stabilized in the vehicle door.

[0036] Working principle: two wires 22 are respectively inserted into the two wire plugs 21, and the two terminals 23 are crimped onto the two wires 22 and the two wire plugs 21 after plugging, thereby forming two assemblies 2, and then the two assemblies 2 are inserted into the plastic body 1. The encapsulated plastic 3 adopts the plastic mold secondary molding technology to encapsulate the two assemblies 2, so that the two assemblies 2 are sealed and fixed in the plastic body 1. The silicone ring 4 is sleeved on the plastic body 1. The plastic body 1 and the client's socket, through the two wires 22 crimped by the two terminals 23, play the role of signal transmission.
