Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle parts, and in particular relates to a new energy vehicle domain control connector. Background Technology

[0002] Domain control connectors for new energy vehicles are a key component that has emerged with the upgrading of the electronic and electrical architecture of new energy vehicles and the development of the domain-centralized architecture stage. With the use of domain controllers, the demand for connectors has also changed, especially in terms of miniaturization, modularization, and centralization. The disadvantages of traditional domain control connectors for new energy vehicles are: 1. They are usually multiple individual connectors, resulting in poor integration; 2. High-current terminals still use machining processes, leading to high costs; 3. Connector sockets still use copper busbar splicing or wire routing, occupying a large amount of internal space and causing cumbersome wiring harness assembly; 4. The structure is complex, and the wiring harness can only exit horizontally at 180°. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a right-angle 6-core plastic connector with high integration and easy assembly.

[0004] To solve the above problems, the present invention adopts the following technical solution: a plug housing, a set of dual-pin composite female terminals located at the front end of the plug housing via a front baffle, and a set of adapter terminals located at the rear end of the plug housing via a rear core. The front baffle has an integrally formed set of terminal bushings and a set of snap fasteners on its side wall. The dual-pin composite female terminals are located within the terminal bushings. The rear core has a set of terminal slots and a barb on its side wall that connects to the snap fasteners. The adapter terminals have an L-shaped sheet structure and are inserted into the terminal slots. When the front baffle and rear core are installed into the plug housing, the snap fasteners connect to the barbs, and the dual-pin composite female terminals are inserted into the adapter terminals at a 90° angle.

[0005] The terminal slot includes an upper terminal slot located on the back of the rear rubber core and a lower terminal slot located on the front of the rear rubber core. Both the upper and lower terminal slots are provided with hooks for attaching the adapter terminal. The adapter terminal includes an upper adapter terminal inserted into the upper terminal slot and a lower adapter terminal inserted into the lower terminal slot.

[0006] Both the upper terminal slot and the lower terminal slot are provided with wiring channels below them. After the wires are soldered to the upper and lower adapter terminals, they are led out through the wiring channels.

[0007] The rear core is connected to the plug housing via first elastic clips on both sides.

[0008] The plug housing is hinged to an auxiliary handle, and the end of the auxiliary handle is provided with a secondary locking component. The secondary locking component includes a push plate and guide rails on both sides of the lower end of the push plate. The front end of the guide rail is provided with a locking pin, and an anti-drop plate is provided between the guide rails. The auxiliary handle is provided with a guide rail groove that cooperates with the guide rail and a positioning hole that cooperates with the anti-drop plate. The plug housing is provided with a T-shaped post that cooperates with the locking pin.

[0009] The dual-socket composite female terminal includes a dual-socket terminal and a protective sleeve that is fitted over the dual-socket terminal. The protective sleeve is provided with a second elastic locking foot that is connected to the terminal bushing.

[0010] The front baffle is provided with a sealing ring at the rear end, and the plug housing is provided with a wire mesh and a rear cover at the rear end.

[0011] The dual-socket composite female terminal and the adapter terminal each have 6 terminals.

[0012] The advantages of this right-angle 6-core plastic connector are as follows:

[0013] 1. Highly integrated, reducing product size and facilitating assembly;

[0014] 2. Using stamped terminals ensures high consistency, low cost, and stable performance.

[0015] 3. The plug structure is lightweight and features a 90° right-angle cable exit compared to existing products, enriching the layout and wiring options for similar products in vehicles.

[0016] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description
