[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 5This utility model provides a technical solution: a protective device for automotive door wiring harness connectors, comprising a wiring harness 1 and a housing 2. The wiring harness 1 has fixed seats 3 at both ends. A connecting groove is provided inside the fixed seat 3, and a supporting slide rod 4 is provided inside the connecting groove. A connecting plate 5 is slidably connected to the outer surface of the supporting slide rod 4. A triangular connecting block 6 is provided at the upper end of the connecting plate 5. A first spring 7 is provided on the outer surface of the connecting plate 5, with the end of the first spring 7 away from the connecting plate 5 located on the inner wall of the connecting groove. The housing 2 is sleeved on the outer surface of the wiring harness 1. An adjusting top plate 8 is provided on the inner wall of the housing 2. The positions of the adjusting top plate 8 and the connecting plate 5 correspond to each other, and the contact surfaces of the adjusting top plate 8 and the connecting plate 5 are both inclined surfaces. A second spring 9 is provided on the inner wall of the housing 2, with the end of the second spring 9 away from the housing 2 located on the lower surface of the fixed seat 3. A directional slide rod 10 is provided on the bottom surface of the fixed seat 3, and the directional slide rod 10 is slidably connected inside the housing 2. A limit piece is provided at the end of the directional slide rod 10 away from the fixed seat 3.

[0025] Specifically, when the plug of wire harness 1 is inserted into the corresponding socket, the triangular connecting block 6 presses against the corresponding connecting groove, causing the corresponding connecting plate 5 to slide relative to each other and press the first spring 7. As the plug of wire harness 1 continues to be inserted, when the plug of wire harness 1 is fully connected to the socket, the triangular connecting block 6 is inserted into the corresponding connecting groove. Under the elastic force of the first spring 7, the connecting plate 5 is reset, thereby locking the triangular connecting block 6 into the corresponding connecting groove, fixing the position of wire harness 1 and socket. During disassembly, the housing 2 is pushed upward, so that the adjusting top plate 8 contacts the lower side of the connecting plate 5. As the housing 2 continues to be pushed upward, the connecting plate 5 and the triangular connecting block 6 move relative to each other, thereby causing the triangular connecting block 6 to disengage from the corresponding connecting groove, allowing wire harness 1 to quickly disengage from socket. After disengagement, under the elastic force of the second spring 9 (the second spring 9 is a light spring), the housing 2 wraps and protects the pin 11, thereby preventing damage to wire harness 1 during transportation or placement.

[0026] Please see Figure 4 The wire harness 1 has pins 11 at both ends, and there are several pins 11 evenly distributed at both ends of the wire harness 1.

[0027] Specifically, pin 11 ensures the stability of the wiring harness 1 connection.

[0028] Please see Figure 4 The fixed base 3 has several connecting slots, which are evenly distributed inside the fixed base 3. Each connecting slot supports two sliding rods 4.

[0029] Specifically, the multiple sets of connecting slots ensure the stability of the connection between the wiring harness 1 and the corresponding socket.

[0030] Please see Figure 1There are two shells 2, symmetrically distributed at both ends of the wire bundle 1.

[0031] Specifically, the two housings 2 provide protection for the connectors at both ends of the wiring harness 1.

[0032] Please see Figure 3 The number of second springs 9 and directional slide rods 10 is several, and they are evenly distributed on the fixed base 3 and the housing 2.

[0033] Specifically, the arrangement of multiple sets of second springs 9 and directional slide bars 10 ensures the stability of the sliding of the housing 2 and the timely protection of the pin 11.

[0034] Please see Figure 1 The housing 2, the fixed base 3, the connecting plate 5, the triangular connecting block 6, and the adjusting top plate 8 are all made of insulating plastic.

[0035] Specifically, the insulating plastic components ensure the insulation of the protective structure.

[0036] During use, the plug of wire harness 1 is inserted into the corresponding socket. The triangular connecting block 6 presses against the corresponding connecting slot, causing the corresponding connecting plate 5 to slide relative to each other, compressing the first spring 7. As the plug of wire harness 1 continues to be inserted, when the plug of wire harness 1 is fully connected to the socket, the triangular connecting block 6 is inserted into the corresponding connecting slot. Under the elastic force of the first spring 7, the connecting plate 5 is reset, thus locking the triangular connecting block 6 into the corresponding connecting slot, fixing the position of wire harness 1 and socket. During disassembly, the housing 2 is pushed upward, causing the adjusting top plate 8 to contact the lower side of the connecting plate 5. As the housing 2 continues to be pushed upward, the connecting plate 5... The triangular connecting block 6 moves relative to the wire harness 1, causing it to disengage from the corresponding connecting slot. This allows the wire harness 1 to quickly disconnect from the socket. After disconnection, the second spring 9 (a lightweight spring) acts as a spring force, causing the housing 2 to wrap and protect the pin 11. This prevents damage to the wire harness 1 during transportation or placement. Consequently, the automotive door wire harness connector protection device improves the connection stability of the wire harness 1 connector, facilitates quick disassembly and installation of the wire harness 1, and enhances the protection of the wire harness 1 pin 11.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
