Description

Technical Field

[0001] This utility model belongs to the field of connectors, and in particular relates to a wiring harness connector for automobiles. Background Technology

[0002] Automotive wiring harness connectors are crucial components in automotive circuits, used to connect various electrical and electronic parts. They typically consist of terminals, housings, mounting brackets, sealing components, and locking components. With the rapid development of new energy vehicles, wiring harness connectors are also widely used in these vehicles. Because new energy vehicles have far more power and signal wires than traditional vehicles, and traditional automotive wiring harness connectors connect fewer and simpler wires, numerous connectors are needed to complete the connection, leading to cumbersome, messy, and error-prone wiring. To address these issues, Chinese utility model patent CN 109980394B, entitled "A Wiring Harness Assembly Connector and Wiring Harness Assembly," proposes a solution that integrates multiple power and signal wiring harness connectors into a socket to facilitate user-side wiring. However, a drawback remains: the retainer (mounting bracket) for fixing the terminals is inserted from the rear of the connector housing and connected to the housing via hooks at both ends, resulting in poor stability and inconvenient assembly and disassembly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automotive wiring harness connector with good stability and easier disassembly and assembly.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a wire harness socket, the wire harness socket including a socket housing and a set of pin terminals disposed at the bottom of the socket housing, the bottom of the socket housing being provided with a set of socket holes adapted to the pin terminals, characterized in that: a backstop latch is inserted into one side of the socket housing, the backstop latch is provided with guide rails on both sides and a set of spaced-apart locking strips in the middle, a set of opposing locking blocks is provided between the locking strips and the locking blocks are embedded in the socket holes, and a slot for the guide rails to be inserted is provided on one side of the wire harness socket.

[0005] The automotive wiring harness connector is characterized in that: both ends of the retaining strip are provided with positioning ribs that cooperate with the socket housing for positioning.

[0006] The automotive wiring harness connector is characterized in that: the guide rail is provided with a hook that connects to the socket housing, and the wiring harness socket is provided with a hanging groove that connects to the hook.

[0007] The automotive wiring harness connector is characterized in that: the two ends of the locking block are provided with inclined guide surfaces.

[0008] The automotive wiring harness connector is characterized in that: a composite positioning sleeve is provided outside the pin terminal, the composite positioning sleeve is provided with figure-eight shaped locking feet on both sides that are connected to the socket, and a square positioning part at the bottom that is connected to the locking block.

[0009] The automotive wiring harness connector is characterized in that: a groove corresponding to the side wall of the anti-reverse latch is provided on one side of the wiring harness socket.

[0010] The automotive wiring harness connector is characterized in that: the slot is wider than the thickness of the guide rail, and the wiring harness socket is provided with an unlocking port next to the hanging slot.

[0011] The advantages of this automotive wiring harness connector are as follows: 1. The anti-reverse latch is connected to the socket housing by a side-plugging method, which makes disassembly and assembly more convenient, has good stability, and does not take up space; 2. When removing the terminal, it is not necessary to remove the entire anti-reverse latch.

[0012] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0019] Reference Figure 1-6As shown, the automotive wiring harness connector of this utility model includes a wiring harness socket 1. The wiring harness socket 1 includes a socket housing 2 and a set of pin terminals 3 disposed at the bottom of the socket housing 2. The pin terminals 3 are typically composed of power terminals and signal terminals. The bottom of the socket housing 2 is provided with a set of socket holes 4 adapted to the pin terminals 3. A locking buckle 5 is inserted into one side of the socket housing 2. Guide rails 6 are provided on both sides of the locking buckle 5. A set of spaced-apart locking strips 7 are provided in the middle of the locking buckle 5. A set of opposing locking blocks 8 are provided between the locking strips 7, and the locking blocks 8 are embedded in the socket holes 4. A slot 11 for inserting the guide rails 6 is provided on one side of the wiring harness socket 1. During assembly, the pin terminals 3 are first inserted into the socket holes 4 of the wiring harness socket 1, and then the locking buckle 5 is inserted. When the locking buckle 5 is inserted in place, the locking blocks 8 engage with the rear end of the pin terminals 3 to prevent them from retracting.

[0020] Preferably, the locking strip 7 has positioning ribs 9 at both ends that engage with the socket housing 2 to improve the stability of the locking strip 7 connection.

[0021] Preferably, the guide rail 6 is provided with a hook 10 that connects to the socket housing 2, and the wire harness socket 1 is provided with a hanging groove 12 that connects to the hook 10, so as to fix the anti-reverse buckle 5. The slot 11 is wider than the thickness of the guide rail 6, and the wire harness socket 1 is provided with an unlocking port 18 next to the hanging groove 12. When it is necessary to remove the anti-reverse buckle 5, a rod-like object (such as a screwdriver) is inserted into the unlocking port 18 to move the hook 10 away from the unlocking port 18.

[0022] Preferably, the card block 8 has inclined guide surfaces 13 at both ends, which allow for smoother insertion of the end of the pin terminal 3.

[0023] Preferably, the pin terminal 3 is provided with a composite positioning sleeve 14. The composite positioning sleeve 14 has figure-eight shaped locking feet 15 on both sides that connect to the socket 4, and a square positioning part 16 at the bottom that connects to the locking block 8. The figure-eight shaped locking feet 15 engage with the step inside the socket 4. The pin terminal 3 is usually made of copper plate, and the composite positioning sleeve 14 is usually made of stainless steel plate, forming a copper-aluminum composite structure when combined. This structure improves the connection strength of the pin terminal 3.

[0024] Preferably, the wire harness socket 1 has a groove 17 on one side that corresponds to the side wall of the anti-reverse latch 5. The anti-reverse latch 5 can be removed more easily through the groove 17.

[0025] The foregoing is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
