Technical Field
[0001] This utility model relates to the field of automotive wiring harness connector technology, specifically a multi-functional anti-loosening device for automotive wiring harness connectors. Background Technology
[0002] Wire harness connectors, also known as plugs, are a type of terminal block consisting of a plug and a socket. They are mainly used in automotive electrical circuits for wire harness connections, serving as electrical relays between electrical devices. They employ a locking mechanism to ensure connection stability and prevent vibration-induced detachment; the locking mechanism must be released before disassembly.
[0003] Wiring harness connectors can become loose due to impacts during installation. Existing connectors are prone to detachment under pulling force, causing them to separate and affecting subsequent use. Furthermore, after initial connection, it's difficult to quickly align the connectors, resulting in slow installation and disassembly. Utility Model Content

[0010] In some embodiments, the inner side of the end of the barb is a bevel, and the outer side of the end of the barb is a plane.
[0011] In some embodiments, there are two first latching assemblies and two second latching assemblies, with the two first latching assemblies fixedly connected to the two symmetrical sides of the first connector, and the two second latching assemblies fixedly connected to the two symmetrical sides of the second connector.
[0012] In some embodiments, the first magnetic assembly includes an L-shaped mounting plate and a first magnetic piece, wherein the side of the L-shaped mounting plate is fixedly connected to the side of the first connector, and the bottom surface of the L-shaped mounting plate is fixedly connected to the first magnetic piece.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] See Figure 1The present invention provides a schematic diagram of the structure of a multi-functional anti-loosening device for automotive wiring harnesses, including a first connector 1 and a second connector 2. The first connector 1 is provided with a first anti-loosening mechanism on its side, and the second connector 2 is provided with a second anti-loosening mechanism on its side. The first anti-loosening mechanism includes a first snap-fit assembly 11 and a first magnetic attraction assembly 12. The second anti-loosening mechanism includes a second snap-fit assembly 21 adapted to the first snap-fit assembly 11 and a second magnetic attraction assembly 22 adapted to the first magnetic attraction assembly 12.
[0028] When the first connector 1 is connected to the second connector 2, the first snap-fit assembly 11 is snap-fitted to the second snap-fit assembly 21, and the first magnetic attraction assembly 12 is magnetically attracted to the second magnetic attraction assembly 22.
[0029] In this embodiment, by providing a first snap-fit assembly 11 and a first magnetic attraction assembly 12 on the first connector 1, and a second snap-fit assembly 21 and a second magnetic attraction assembly 22 on the second connector 2, the first connector 1 and the second connector 2 are simultaneously connected by snap-fit and magnetic attraction, thereby improving the stability of the connection. At the same time, the magnetic force of the first magnetic attraction assembly 21 and the second magnetic attraction assembly 22 can quickly adjust the orientation of the connectors, allowing the two connectors to be quickly aligned and installed. Furthermore, the snap-fit connection and the magnetic attraction connection are easy to disassemble, thereby achieving quick installation and disassembly and improving convenience.
[0030] like Figure 2 and 3 As shown, in some embodiments, the first buckle assembly 11 includes a protective frame 111, a torsion spring 112, and an adjusting plate 113. The protective frame 111 is fixedly connected to the side of the first connector 1, the torsion spring 112 is fixedly connected to the two inner sides of the protective frame 111, and one end of the adjusting plate 113 is rotatably connected to the torsion spring 112.
[0031] The second buckle assembly 21 includes a limiting plate 211 and a push-out block 212. One end of the limiting plate 211 is fixedly connected to the side of the second connector 2, and the other end of the limiting plate 211 is provided with a barb 213 adapted to the adjusting plate 113. The push-out block 212 is located between the barb 213 and one end of the limiting plate 211.
[0032] Optionally, the limiting plate 211 is T-shaped, and the depth of the protective frame 111 is greater than the length of the other end of the limiting plate 211, so that the limiting plate 211 can penetrate into the protective frame; the height of the push-out block 212 is higher than the height of the barb 213 and lower than the installation height of the torsion spring 112, so that the push-out block 212 can pass smoothly under the torsion spring 112 and push the adjusting plate 113 to a position higher than the barb 213, thereby separating the barb 213 from the adjusting plate 113.
[0033] Optionally, the inner side of the end of the barb 213 is a bevel, and the outer side of the end of the barb is a plane, so as to improve the fit between the barb 213 and the adjusting plate 113.
[0034] Optionally, there are two of each of the first latching assembly 11 and the second latching assembly 21. The two first latching assemblies 11 are respectively fixedly connected to the two symmetrical sides of the first connector 1, and the two second latching assemblies 21 are respectively fixedly connected to the two symmetrical sides of the second connector 2, so as to improve the connection stability of the two connectors.
[0035] In this embodiment, protective frames 111 are installed on the upper and lower sides of the first connector 1. An adjusting plate 113 is installed inside the protective frames 111 via torsion springs 112 on both sides. Limiting plates 211 are installed on the upper and lower sides of the second connector 2, with barbs 213 fixed to their ends. The inner side of the top surface of the barb 213 is designed with an inclined structure. When the two connectors are connected, the limiting plate 211 of the second connector 2 is inserted into the protective frame 111 of the first connector 1. During this process, the barb 213 at the end of the limiting plate 211 pushes upward against the adjusting plate 113 inside the protective frame 111, forcing the adjusting plate 113 to overcome the resistance of the torsion springs 112 and move upward. As the insertion deepens, when the barb 213 completely passes the adjusting plate 113, the adjusting plate 113 rotates downward under the action of the torsion springs 112, forming a [missing information - likely a specific shape or structure]. Figure 2 The snap-fit connection shown locks the connector. When separating the two connectors, push the limiting plate 211 further forward so that the push-out block 212 pushes the adjusting plate 113 upward, releasing its snap-fit with the barb 213 (as shown). Figure 3 (As shown), the barb 213 can then be pulled out, causing the limiting plate 211 to exit from the protective frame 111, thus separating the joint.
[0036] like Figure 4 As shown, in some embodiments, the first magnetic suction assembly 12 includes an L-shaped mounting plate 121 and a first magnetic suction piece 122. The side of the L-shaped mounting plate 121 is fixedly connected to the side of the first connector 1, and the bottom surface of the L-shaped mounting plate 121 is fixedly connected to the first magnetic suction piece 122.
[0037] The second magnetic attraction assembly 22 includes a connecting plate 221, a second magnetic attraction piece 222, a mounting plate 223, a fixing plate 224, and a spring rod 225. The mounting plate 223 is fixedly connected to the side of the second connector 2. After passing through the mounting plate 223, one end of the spring rod 225 is fixedly connected to one side of the connecting plate 221, and the other end is fixedly connected to the fixing plate 224. The other side of the connecting plate 221 is fixedly connected to the second magnetic attraction piece 222. The two ends of the spring rod 225 are respectively fixedly connected between the connecting plate 221 and the fixing plate 224.
[0038] Optionally, the first distance between the connecting plate 221 and the mounting plate 223 in the spring's natural state is greater than the second distance in the spring's stretched state. This causes the second magnetic absorbing piece 222 to be subjected to a force close to the first magnetic absorbing piece 122 under the action of the spring, improving the magnetic attraction; at the same time, it facilitates the adjustment of the position of the connecting plate 221 when the latching assembly is released, preventing the position of the second magnetic absorbing assembly from affecting the operation of the latching assembly and ensuring the smooth operation of the latching assembly.
[0039] Optionally, there are two of each of the first magnetic attraction component 12 and the second magnetic attraction component 22. The two first magnetic attraction components 12 are respectively fixedly connected to the other two symmetrical sides of the first connector 1, and the two second magnetic attraction components 22 are respectively fixedly connected to the other two symmetrical sides of the second connector 2. The two sets of magnetic attraction components can ensure quick alignment of the connectors under the action of magnetic attraction, improving the ease of installation.
[0040] In this embodiment, a first magnetic piece 122 is mounted on the L-shaped mounting plate 121. The first magnetic piece 122 is attracted to a second magnetic piece 222 located on the connecting plate 221. The mounting plate 223 has an insertion hole inside, through which the spring rod 225 passes and connects to the connecting plate 221 and the fixing plate 224. When the connector is connected, the barb 213 moves into the protective frame 111, and the spring rod 225 drives the connecting plate 221 to move accordingly, so as to prevent the magnetic connection between the first magnetic piece 122 and the second magnetic piece 222 from accidentally disengaging. When the connector is separated, the limiting plate 211 is pushed further into the protective frame 111, and the connecting plate 221 moves in the opposite direction to stretch the spring on the spring rod 225, thereby not affecting the movement of the buckle assembly.
[0041] like Figure 5 As shown, in some embodiments, the front end of the first connector 1 is provided with a U-shaped groove 13, and the front end of the second connector 2 is provided with a connecting plate 23 adapted to the U-shaped groove 13; when the first connector 1 and the second connector 2 are connected, the U-shaped groove 13 is inserted into the connecting plate 23. Optionally, a silicone ring 24 is provided at one end of the connecting plate 23 away from the U-shaped groove 13.
[0042] In this embodiment, the first connector 1 has a U-shaped groove 13, and the second connector 2 is equipped with a connecting plate 23. The connecting plate 23 is fixed to the thickened silicone ring 24, and the elastic structure of the silicone ring 24 facilitates the removal of the barb 213. When the two connectors are connected, the connecting plate 23 is embedded in the U-shaped groove 13, which covers the connection gap between the two connectors and improves the connection sealing.
[0043] As an example and not a limitation, when the first connector 1 and the second connector 2 are inserted, under the magnetic attraction of the first magnetic attraction component 21 and the second magnetic attraction component 22, the first connector 1 and the second connector 2 quickly align. The connecting plate 23 on the second connector 2 is embedded in the U-shaped groove 13 of the first connector 1, and the silicone ring 24 covers the connection gap. The limiting plate 211 is carried into the protective frame 111, and the inclined top surface of the barb 213 pushes the adjusting plate 113 upward, forcing the adjusting plate 113 to overcome the torque of the torsion spring 112 and rotate upward (in an approximately straight line state). When the barb 213 completely passes the adjusting plate 113 and penetrates into the interior of the protective frame 6, the lower part of the adjusting plate 113 is no longer obstructed, and the adjusting plate 113 rotates downward and resets under the action of the torsion spring 7. Its lower end forms a shape with the barb 213 as shown in the figure. Figure 2 The buckle connection shown locks the connector, and at the same time, the first magnetic absorbing piece 122 and the second magnetic absorbing piece 222 on the left and right sides of the first connector 1 and the second connector 2 attract each other.
[0044] When disassembling the first connector 1 and the second connector 2, push the limiting plate 211 to move the barb 213 a short distance deeper into the protective frame 111. The push-out block 212 at the side end of the barb 10 then penetrates deeper into the protective frame 111. The push-out block 212 pushes the adjusting plate 113 upwards, forcing the adjusting plate 113 to overcome the torque of the torsion spring 112 and rotate upwards again (in an approximately straight line state), thus separating the barb 213 from the adjusting plate 113. After releasing the snap-fit connection, move the barb 213 together with the push-out block 212 outwards from the protective frame 111 and pull them out. Continue pulling out the barb 1213 and... The push block 212 will push the adjusting plate 113 to keep it in a straight line. The push block 212 eventually moves to the outside of the torsion spring 112, and the barb 213 pushes the adjusting plate 113. After the barb 213 is completely pulled out, the second connector 2 will pull the limiting plate 211 out of the protective frame 111. When the barb 213 moves into the protective frame 111 for initial unlocking, the spring rod 225 will drive the connecting plate 221 to move, ensuring that the magnetic attraction between the first magnetic piece 122 and the second magnetic piece 222 will not break immediately at the moment the connector begins to separate, providing buffering and assisting positioning.

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.
