[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of an automotive connector according to the present utility model is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0032] Please refer to Figures 1-6 An automotive connector, comprising:

[0033] The first terminal 100 has a first anti-recoil part 110 in the middle part 430;

[0034] The second terminal 200 has a second anti-recoil part 210 in the middle part 430;

[0035] The outer casing 300 includes an integrally formed plate 310, a first socket 320 and a second socket 330. The first socket 320 and the second socket 330 are spaced apart on the front side of the plate 310. The inner walls of the first socket 320 and the second socket 330 are provided with anti-foolproof ribs 321. A sealing groove 311 is provided on the front side of the plate 310 near the edge. The sealing groove 311 is provided with a plurality of extrusion protrusions 3111. The first terminal 100 and the second terminal 200 are integrally formed and pass through the plate 310 and are located in the first socket 320 and the second socket 330. The first anti-recoil part 110 and the second anti-recoil part 210 are located in the plate 310.

[0036] The sealing ring 500 is configured in the sealing groove 311.

[0037] The first socket 320 and the second socket 330 are directly mounted on a housing 300, directly corresponding to the two interfaces of the VCU vehicle controller, eliminating the need for separate connectors and providing convenience and speed. The inner walls of both the first socket 320 and the second socket 330 are equipped with anti-misfit ribs 321 to prevent incorrect insertion. Multiple components are integrally formed from the housing 300, simplifying processing, reducing production costs, and ensuring high connection strength. The first anti-retraction part 110 of the first terminal 100 and the second anti-retraction part 210 of the second terminal 200 are formed within the plate 310, preventing loosening of the terminals due to insertion retraction. A sealing groove 311 is provided on the edge of the main body, and a compression protrusion 3111 is provided within the sealing groove 311, allowing the sealing ring 500 to protrude from the end face of the plate 310. Under sealing pressure, the ring deforms into the gap between the compression protrusions, thereby achieving a better sealing effect.

[0038] Please refer to Figures 1-3 The plate 310 has several blind mounting holes 312 opening to the front within the sealing groove 311. Each blind mounting hole 312 protrudes to the back, and a metal nut 400 is integrally formed within each blind mounting hole 312. Using the metal nut 400 improves connection strength and service life. The metal nut 400 is also installed integrally with the outer shell 300, making the process simple, convenient, and the connection secure. Generally, the metal nut 400 is made of materials such as carbon steel, alloy steel, copper alloy, or stainless steel.

[0039] Preferably, the protrusion height of the mounting blind hole 312 towards the back is greater than the protrusion height of the first terminal 100 and the second terminal 200 towards the back. This increases the effective height of the metal nut 400, thereby ensuring connection stability without increasing the thickness of the plate 310.

[0040] Please refer to Figure 3 and Figure 6The metal nut 400 comprises a top 410, a middle 430, and a bottom 450. The outer wall between the top 410 and the middle 430 has a first annular groove 420, and the outer wall between the middle 430 and the bottom 450 has a second annular groove 440. This makes the metal nut 400 more stable and the connection between it and the housing 300 more secure.

[0041] Please refer to Figure 3 and Figure 6 The outer wall of the metal nut 400 is provided with several limiting ribs 460 to prevent the metal nut 400 from loosening due to rotation.

[0042] Please refer to Figure 2 The back of the plate 310 is provided with an asymmetrically arranged first positioning protrusion 313 and second positioning protrusion 314. The first positioning protrusion 313 is located at one end of the plate 310, and the second positioning protrusion 314 is located at the other end of the plate 310. The asymmetrical arrangement of the two positioning protrusions facilitates foolproof connection with other parts.

[0043] Please refer to Figure 2 The back of the plate 310 is provided with several reinforcing ribs 315 to improve the strength of the outer shell 300 and prevent the outer shell 300 from breaking.

[0044] Please refer to Figure 2 The back of the board 310 is recessed towards the front at the locations corresponding to the first socket 320 and the second socket 330. This facilitates plugging and unplugging connections on the back of the board 310.

[0045] Please refer to Figure 4 and Figure 5 The first anti-recoil portion 110 and the second anti-recoil portion 210 are either a raised plate 211 or a barbed plate 111. It is understood that the barbed plate 111 is formed by a gradual increase in width from the front to the back side to create a barb shape. It is also understood that multiple raised plates 211 and barbed plates 111 can be provided along the length of the terminal as needed.

[0046] Please refer to Figure 1 and Figure 3 Both the first socket 320 and the second socket 330 have symmetrical locking tongues 322 on their outer walls. The locking tongues 322 facilitate the locking of the automotive connector with the VCU vehicle controller interface. Simply put, the locking tongue 322 is semi-cylindrical, and the VCU controller also has a semi-cylindrical body that matches the locking tongue 322. The two parts fit together to form a cylinder, and are then locked in place by a nut or rivet ring.

[0047] Specifically, the 500 double convex ring sealing ring has two spaced convex strips on the end face of the sealing ring.

[0048] Understandably, the first terminal 100 and the second terminal 200 are two types of terminals with different specifications, and the outer diameter of the second terminal 200 is larger than that of the first terminal 100. Typically, the first socket 320 has 4*14=56 first terminals 100 and 4*2=8 second terminals 200; the second socket 330 has 4*10=40 first terminals 100 and 4*2=8 second terminals 200; for a total of 112 terminals.

[0049] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0050] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0051] In summary, the automotive connector provided by this utility model directly integrates a first socket and a second socket onto a single housing, directly corresponding to the two interfaces of the VCU vehicle controller, eliminating the need for separate connectors and offering convenience and speed. Both the first and second sockets have anti-misalignment ribs on their inner walls to prevent incorrect insertion. Multiple components are integrally molded into a single unit, simplifying processing, reducing production costs, and ensuring high connection strength. The first anti-retraction portion of the first terminal and the second anti-retraction portion of the second terminal are formed within the plate body, preventing loosening due to terminal retraction during insertion. A sealing groove is provided at the edge of the body, with extrusion protrusions within the groove, allowing the sealing ring to protrude from the end face of the plate body. Under sealing pressure, the ring deforms into the gap between the extrusion protrusions, achieving a better sealing effect.
