[0038] An automotive connector, such as Figure 1 As shown, it includes a male socket 4 and a female socket 1. The female socket 1 is fixed to the car. A contact 5 is provided inside the male socket 4. The female socket 1 is plugged into the male socket 4. One end of the contact 5 is connected to the car's connecting line inside the female socket 1, and the other end of the contact 5 is connected to the external connecting line. The car's connecting line and the external connecting line are connected to the contact 5 to achieve circuit connectivity at both ends, thereby realizing various electrical functions.

[0039] In this embodiment, if Figure 2As shown, a female connector 1 has three male connector sockets protruding from it. These are hollow, square holes. The upper connector hole 102 has a larger cross-sectional area than the lower connector hole 103. The upper connector hole 102 connects to the male connector 4, while the lower connector hole 103 connects to the vehicle's wiring harness. A step is provided between the upper and lower connector holes 102, limiting the position of the male connector 4 when it is inserted into the female connector 1 from above. The front end of the upper male connector hole is recessed to form a snap-fit groove 101. The inner wall of the lower connector hole 103 is provided with several vertical grooves to accommodate the springs 503 of the contacts 5 on various external wiring harnesses. The three male connector sockets correspond to three different types of external wiring harnesses. Different types of male connectors 4 are inserted into the corresponding male connector holes and connected to the female connector 1. The upper connector hole 102 of the male connector can be provided with mounting grooves of different positions and shapes, either concave or convex, on the inner wall, as needed.

[0040] The male socket of the female connector 1 is covered with a fixing frame 2, which passes through the female connector 1 from top to bottom and has several fixing keys 201 extending from the bottom of the female connector 1. The female connector 1 is fixed to the car through the fixing keys 201. The fixing frame 2 is made of metal.

[0041] A snap-fit frame 3 is located above the fixed frame 2 and fits over the male receptacle. Made of plastic, the snap-fit frame 3 has a fractured front end, forming an opening slot that matches the snap-fit slot 101 on the female receptacle 1 in both position and shape. The inner wall of the snap-fit frame 3 is equipped with a snap-fit damper, which secures the snap-fit frame 3 to the male receptacle of the female receptacle 1.

[0042] The entire body of the female connector 1 is made of plastic. During production, a metal sheet is bent or stamped to form a fixed frame 2. This frame is then placed in a mold, and molten plastic is injected into the mold. Once the plastic solidifies, the female connector 1 is formed, and the snap-fit frame 3 is snap-fitted to the male socket of the female connector 1. To ensure heat dissipation in the connector and conserve material, multiple slots are provided on both the female connector 1 and the fixed frame 2. These slots also allow for snap-fitting during assembly between the vehicle and the female connector 1, strengthening the connection between the two.

[0043] Figure 4As shown, the male socket 4 includes a contact 5 and a housing 403. The contact 5 is disposed inside the housing 403. A latch 402 is disposed on the surface of the housing 403. Both ends of the latch 402 are fixedly connected to the surface of the male socket 4. A protrusion on the surface of the latch 402 forms a lock 401. The locking groove 101 and the lock 401 are engaged, thereby fixing the male socket 4 and the female socket 1. The front end of the housing 403 is convex, and a retaining plate 404 is provided on the side. The front end of the retaining plate 404 extends out of the front end face. When the male socket 4 is plugged into the female socket 1, the protrusion is embedded in the groove of the male socket jack to fix the relative position of the male socket 4 and the female socket 1. The spring key 402 is pressed inward under the pressure of the inner wall of the male socket jack. When the lower end face of the male socket 4 contacts the step, the retaining plate 404 also presses against the upper end face of the male socket jack, and the male socket 4 is in the required assembly position. At the same time, the lock 401 pops out from the snap-fit groove 101, fixing the male socket 4 and the female socket 1. The spring key 402 is also provided with friction grooves 405 to enhance the feel when plugging the male socket 4 and the female socket 1 and provide a fulcrum.

[0044] like Figure 2 As shown, the contact member 5 includes a metal frame, a contact spring 502 and a spring 503 , and the contact spring 502 and the spring 503 are arranged inside the metal frame.

[0045] like Figure 3 、 Figure 5 、 Figure 6 As shown, the spring clips 503 and the contact spring clips 502 each have four pieces, positioned at the four corners of the metal frame. The spring clips 503 and contact spring clips 502 are arranged vertically in sequence along the metal frame. The four spring clips 503 are isolated by a first insulator 501. The first insulator 501 is positioned at the center of the metal frame and has opposing mounting grooves 50102 at each end, with two isolated mounting grooves 50102 at each end. The four spring clips 503 are respectively positioned in these mounting grooves 50102. The upper ends of the first insulator 501 are provided with fixing grooves 50101, and fixing blocks 504 are disposed on the fixing grooves 50101. The fixing blocks 504 secure the spring clips 503 to the first insulator 501. Two spring clips 503 at the same end are secured by the same fixing block 504. The fixing block 504 is also made of an insulating material. The four contact springs 502 are isolated by a second insulator 507, which is sleeved over the contact springs 502. A channel is defined within the second insulator 507, through which the contact springs 502 are disposed, with their lower ends extending outside the second insulator 507. The first insulator 501 is plugged into the second insulator 507, with the lower portion of the first insulator 501 disposed within the second insulator 507. The springs 503 are connected to the contact springs 502 within the first insulator 501.

[0046] like Figure 5As shown, the spring pieces 503, which are distributed along the same vertical line, are in contact with the contact spring piece 502. The bottom end of the spring piece 503 is bent and forms a limiting hook at the tail end. The upper portion of the contact spring piece 502 is provided with a first limiting hole 50201 and a second limiting hole 50202. The bottom end of the spring piece 503 passes through the first limiting hole 50201 and passes back through the second limiting hole 50202. The limiting hook 50301 hooks the second limiting hole 50202, so that the spring piece 503 and the contact spring piece 502 are in contact with each other at the positions of the first limiting hole 50201 and the second limiting hole 50202.

[0047] like Figure 5 As shown, the spring piece 503 and the contact spring piece 502 are both flat, elongated metal narrow pieces, each of which is provided with a raised key, and each of which is provided with serrations at both ends. The raised key and serrations facilitate the flow of liquid plastic during injection molding and serve to fix the plastic when it solidifies.

[0048] like Figure 3 As shown, the metal frame includes a first metal frame 505 and a second metal frame 506. The first metal frame 505 is disposed outside the second metal frame 506 and is disposed above the second metal frame 506. A concave contact key is disposed at the lower portion of the surface of the first metal frame 505, through which the first metal frame 505 and the second metal frame 506 are in contact with each other. The first metal frame 505 and the second metal frame 506 are both formed by bending and splicing metal sheets. The lower portion of the second metal frame 506 is provided with two vertical narrow metal sheets, similar to the lower portion of the contact spring 502.

[0049] A raised first connection key is provided on the upper surface of the first metal frame 505, and a raised second connection key is provided on the lower surface of the second metal frame 506. When the male socket 4 is connected to the vehicle connector cable and the external connection cable, the spring clip 503 and the first connection key connect to the external connection cable, while the contact spring clip 502 and the second connection key connect to the vehicle connection cable.

[0050] To manufacture the male socket 4, the spring 503 and the contact spring 502 are first connected, then placed in a mold and injection molded to form the first insulator 501 and the second insulator 507. The time difference in condensation forms the two parts, and then the first metal frame 505 and the second metal frame 506 are covered. The parts can be inserted and pressed tightly, or the metal sheets can be directly bent on the surface to form the first metal frame 505 and the second metal frame 506. The fixing block 504 is then pressed into the semi-finished product. Finally, the semi-finished product is placed in a mold and injection molded to form the shell 403, that is, the male socket 4 is formed. After the male socket 4 is formed, the external connecting wires are connected to the upper part of the male socket 4, so that the external connecting wires are in contact with the upper part of the contact 5. A terminal block can be set at the connection between the external connecting wires and the male socket 4 to concentrate the external connecting wires.

[0051] When the present invention is used, the car's connecting line is first inserted into the lower connecting hole 103 of the male socket jack, and the female socket 1 is fixed in the corresponding position using the fixed key 201 of the female socket 1. Then, the external connecting line is connected and fixed to the upper part of the male socket 4. In this way, the male socket 4 and the female socket 1 are each connected to the working circuit at one end. Then, the male socket 4 is inserted into the upper connecting hole 102 of the female socket 1 until the lock 401 on the male socket 4 is engaged with the snap-fit groove 101 of the female socket 1. At this time, the contact piece 5 of the male socket 4 is connected to the car's connecting line in the female socket 1, realizing the connection of the male socket 4 circuits at both ends. Through the connection between the male socket 4 and the female socket 1, the connection of two circuits that are inconvenient to connect and blocked can be completed. It is simple and convenient, the manufacturing process is simple, and industrial mass production can be achieved. The connection between the contact spring 502 and the second metal frame 506, and the contact area between the spring 503 and the first metal frame 505 are large. At the same time, due to the snapping action of the lock 401 and the snapping groove 101, the male socket 4 and the female socket 1 can be tightly connected without loosening or falling off. During the operation of the car, there will be no poor contact or unstable operation, thereby ensuring the normal operation of the equipment.
