Description

Technical Field

[0001] This utility model relates to the field of wiring harness connection technology, specifically to a plug-in structure for an automotive sensor assembly wiring harness. Background Technology

[0002] Automotive sensor harnesses are integrated wiring harness assemblies that connect multiple sensors to control units, actuators, and other components in an automotive circuit system. During harness assembly, adjacent harnesses need to be plugged in, requiring a plug-in structure. For example, patent document CN220585588U discloses a plug-in structure for automotive sensor harnesses. In this structure, when the plug is inserted into the socket, the lower end of the plug contacts the anti-slip strip A. After insertion, the U-shaped moving frame is pressed down, and the limiting slider moves downward within the limiting groove. The tension spring is stretched, and the plastic insert is inserted into the top groove. As the plastic insert penetrates deeper, the inner moving plate moves downward, the compression spring A contracts, and the limiting round strip moves into the inner slot. The sealing rings A and B deform due to mutual compression, sealing the socket and plug. The U-shaped moving frame and U-shaped placing frame hold the plug in place, and the anti-slip strips B and A prevent the plug from falling out.

[0003] However, when the above-mentioned plug-in mechanism is used for plugging, both sides of the socket end need to be opened before it can be connected to the plug. The overall plugging process is cumbersome and not convenient for quick assembly and disassembly, which reduces the effectiveness of the plug-in structure. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a plug-in structure for an automotive sensor assembly harness.

[0026] Example 1

[0027] This utility model provides, for example Figure 1-4 The diagram shows a plug-in structure for an automotive sensor harness assembly, comprising a first harness 1 and a second harness 2. A socket 3 and a plug 4 are fixedly mounted near one end of the first harness 1 and the second harness 2, respectively. The plug 4 is plugged into the socket 3. Socket holes 5 are provided on both sides of the socket 3. Two symmetrically arranged grooves are provided on the outer wall of the plug 4. A support rod 6 is fixedly mounted on the inner wall of the grooves. A retaining plate 7 is rotatably fitted onto the wall of the support rod 6. The upper end of the retaining plate 7 extends into the socket hole 5. A torsion spring 8 is fitted onto the wall of the support rod 6. The two ends of the torsion spring 8 are fixedly connected to the support rod 6 and the retaining plate 7, respectively.

[0028] Example 2

[0029] Example 2, based on Example 1, aims to enable quick and convenient insertion of the card plate 7 into the groove, thereby connecting the plug 4 and socket 3. Figure 3-4 As shown, the outer wall of the socket 3 has two symmetrically arranged moving slots. The inside of the moving slots is provided with a pressing and separating mechanism for driving the card plate 7 to retract. The pressing and separating mechanism includes a push plate 9 and a pressure plate 10. The inner wall of the socket 5 is fixedly provided with a horizontal plate 11. The longitudinal section of the horizontal plate 11 is rectangular. The inside of the pressure plate 10 is provided with a sliding hole. The horizontal plate 11 is slidably disposed in the sliding hole. A spring 12 is fixedly provided between the horizontal plate 11 and the inner wall of the sliding hole. The inner wall of the moving slot is fixedly provided with an elastic telescopic rod 13. The push plate 9 is located in the moving slot and is fixedly connected to the elastic telescopic rod 13. The end of the push plate 9 is in contact with the pressure plate 10. The upper end of the pressure plate 10 is inclined on the side near the push plate 9. The outer wall of the push plate 9 is fixedly provided with a push block 14. The upper surface of the push block 14 is arc-shaped.

[0030] Working principle: When it is necessary to connect the first wire harness 1 and the second wire harness 2, the plug 4 is aligned with the socket 3 and inserted. During the insertion process, the retaining plate 7 is squeezed by the inner wall of the socket 3, rotates around the support rod 6 and compresses the torsion spring 8. The retaining plate 7 gradually retracts into the groove. When the plug 4 is fully inserted into the socket 3, the retaining plate 7 is reset under the elastic force of the torsion spring 8, and the upper end extends into the socket 5, realizing the snap-fit ​​fixation between the plug 4 and the socket 3, and completing the connection of the first wire harness 1 and the second wire harness 2.

[0031] When it is necessary to separate the first wire harness 1 and the second wire harness 2, press the push block 14 to drive the push plate 9 to move in the moving groove. The elastic telescopic rod 13 is compressed. During the movement of the push plate 9, it comes into contact with the pressure plate 10. Since the upper end of the pressure plate 10 is set at an angle near the push plate 9, the push plate 9 pushes the pressure plate 10 to slide along the horizontal plate 11. The spring 12 is compressed. During the movement of the pressure plate 10, pressure is applied to the clamping plate 7, causing the clamping plate 7 to rotate around the support rod 6 and compress the torsion spring 8. The upper end of the clamping plate 7 exits from the socket 5 and retracts into the groove. At this time, the plug 4 can be pulled out from the socket 3. After releasing the push block 14, the push plate 9 is reset under the elastic force of the elastic telescopic rod 13, the pressure plate 10 is reset under the elastic force of the spring 12, and the clamping plate 7 is also restored to its original position under the elastic force of the torsion spring 8.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
