Technical Field

[0001] This utility model relates to the field of electrical plug technology, specifically to a locking structure to prevent accidental unplugging. Background Technology

[0002] A wire harness connector (or wire harness socket) is a device used for electrical connections. It typically consists of multiple conductive contacts and a housing, used to connect cables or wires to form an electrical connection. Wire harness connectors are widely used in various electronic and electrical devices, including automobiles, home appliances, and industrial equipment.

[0003] Existing cable connectors are prone to detachment during use due to external impacts or vibrations, or due to accidental disconnection by personnel, which can lead to power outages and damage to equipment. This is especially true in cases where multiple interfaces are connected in series, where personnel often disconnect the wrong interface, resulting in accidents. Therefore, existing cable harness interfaces still have certain shortcomings in practical use.

[0004] In conclusion, it is necessary to invent a locking structure that prevents accidental removal. Utility Model Content

[0005] Therefore, this utility model provides a locking structure to prevent accidental disconnection, in order to solve the problem that, especially in the case of multiple interfaces connected in series, personnel often disconnect the wrong interface, resulting in power loss and damage to the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a locking structure to prevent accidental disconnection, comprising a middle connecting socket, a left-end plug connected to a socket on the left side of the middle connecting socket, a right-end plug connected to a socket on the right side of the middle connecting socket, a first locking structure between the left-end plug and the middle connecting socket, and a second locking structure between the middle connecting socket and the right-end plug.

[0007] Preferably, the first locking structure includes a connecting plate, which is fixed to the upper side of the inner wall of the socket end of the left plug, and a connecting hook is provided at the lower end of the connecting plate, which is fixedly connected to the inner wall of the left plug.

[0008] Preferably, a locking frame is fixed at the top of the outer wall of the intermediate connecting socket and at the position corresponding to the connecting plug and the connecting hook. A connecting block is provided at the top of the outer wall of the intermediate connecting socket and inside the locking frame. The two sides of the bottom of the outer wall of the connecting block are fixedly connected to the top of the outer wall of the intermediate connecting socket at the corresponding positions.

[0009] Preferably, the bottom of the outer wall of the connecting plate away from the left plug abuts against the top of the outer wall of the connecting block, and the end of the connecting hook away from the left plug engages with the top of the outer wall of the connecting block and the side close to the right plug.

[0010] Preferably, a baffle is fixed to the outer wall side of the right plug and the side near the middle connecting socket. The outer wall side of the baffle abuts against the right side of the outer wall of the middle connecting socket. The second locking structure includes a right plug buckle, which is fixed to the top of the outer wall of the right plug and the side near the middle connecting socket.

[0011] Preferably, the other end of the right plug buckle is engaged with the bottom of the connecting block near the right plug, and the insertion end of the right plug is fixed with right plug edge buckles on both the front and rear sides of the right plug buckle.

[0012] Preferably, an upper pressure plate is installed at the top of the outer wall of the locking frame through a slot, and a pressure plate buckle is fixed at the bottom of the outer wall of the upper pressure plate at a position corresponding to the edge buckle of the right plug, and the edge buckle of the right plug is engaged with the pressure plate buckle.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, after the user plugs the left plug into the middle connector socket, the connecting hook engages with the connecting block inside the locking frame, pressing the connecting block downwards. The connecting plate also presses the connecting block downwards. When the user then plugs the middle connector socket into the right plug from the other end, the right plug latch engages with the connecting block, pushing the connecting block upwards. This, combined with the downward-pressing connecting hook, improves the stability of the connection between the left plug, the middle connector socket, and the right plug, reducing the chance of accidental disconnection.

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] See attached document Figures 1-8This utility model provides a locking structure to prevent accidental disconnection, including a middle connecting socket 200. A left-side socket of the middle connecting socket 200 is connected to a left-end plug 100, and a right-side socket of the middle connecting socket 200 is connected to a right-end plug 300. A first locking structure is provided between the left-end plug 100 and the middle connecting socket 200. The first locking structure includes a connecting plate 110, which is fixed to the upper side of the inner wall of the socket end of the left-end plug 100. The lower end of the connecting plate 110 is provided with... A connecting hook 120 is provided, which is fixedly connected to the inner wall of the left plug 100. A locking frame is fixed at the top of the outer wall of the middle connecting socket 200, corresponding to the positions of the connecting plate 110 and the connecting hook 120. The locking frame is provided to allow the middle connecting socket 200 to engage with the locking mechanisms on the left plug 100 and the right plug 300. A connecting block 220 is provided at the top of the outer wall of the middle connecting socket 200, inside the locking frame. The connecting block 220 is... To engage with the connecting hook 120 and the right plug latch 320, the bottom sides of the outer wall of the connecting block 220 are fixedly connected to the corresponding top positions of the outer wall of the middle connecting socket 200. The connecting block 220 can be made of plastic, allowing for elastic deformation within a certain range, thus facilitating the insertion and locking of the left plug 100 and the right plug 300. The bottom of the outer wall of the connecting plate 110, away from the left plug 100, abuts against the top of the outer wall of the connecting block 220. The connecting plate 110 is designed to press down on the connecting block 220 after insertion, so that the connecting block 220 moves downward to improve the latching effect between the connecting hook 120 and the right plug latch 320 and the connecting block 220. The end of the connecting hook 120 away from the left plug 100 is latched with the top of the outer wall of the connecting block 220 and the side close to the right plug 300. By latching the connecting hook 120 with the connecting block 220, the left plug 100 and the middle connecting socket 200 can be locked.

[0026] A second locking structure is provided between the intermediate connecting socket 200 and the right plug 300. A baffle 310 is fixed to the outer wall side of the right plug 300 near the intermediate connecting socket 200. The outer wall side of the baffle 310 abuts against the right side of the outer wall of the intermediate connecting socket 200. The second locking structure includes a right plug latch 320, which is fixed to the top of the outer wall of the right plug 300 near the intermediate connecting socket 200. The other end of the right plug latch 320 is connected to the connecting socket 200. The locking block 220 engages at the bottom near the right plug 300. When the right plug latch 320 is inserted into the locking frame and engages with the connecting hook 120, it pushes the connecting block 220 upwards, while the connecting hook 120 engages downwards. The upward movement of the connecting block 220 enhances the locking effect of the connecting hook 120, thereby improving the stability of the left plug 100 and the middle connector 200. Conversely, the connecting hook 120 presses the connecting block 220 downwards. When the connecting block 220 moves downward, it increases the stability of the connection with the right plug latch 320, thereby improving the stability of the connection between the middle connecting socket 200 and the right plug 300. Right plug edge latches 330 are fixed to the insertion end of the right plug 300 and on both the front and rear sides of the right plug latch 320. An upper pressure plate 210 is installed at the top of the outer wall of the locking frame through a slot. A pressure plate latch 211 is fixed at the bottom of the outer wall of the upper pressure plate 210 at a position corresponding to the right plug edge latch 330. The right plug edge clip 330 is engaged with the pressure plate clip 211. The pressure plate clip 211 and the right plug edge clip 330 can further improve the stability of the connection between the middle connector socket 200 and the right plug 300 after engagement. When disassembly is required, the operator can press the end of the upper pressure plate 210 away from the pressure plate clip 211, causing the pressure plate clip 211 to rotate slightly upward. In this way, the right plug edge clip 330 can be separated from the pressure plate clip 211, and the operator can then pull the right plug 300 outward.

[0027] The usage process of this utility model is as follows: First, personnel can produce the left plug 100, the middle connecting socket 200, and the right plug 300 according to the above instructions. Personnel can first insert the left plug 100 into the left side of the outer wall of the middle connecting socket 200. The provided connecting hook 120 will insert into the locking frame and engage with the upper end of the connecting block 220. The connecting plate 110 will press the connecting block 220 downwards. Then, personnel can remove the right plug 300 and insert it from the middle connecting socket. The other end of the socket 200 is inserted, and the right plug buckle 320 can pass through the bottom end of the connecting block 220 and be fastened to the bottom end of the connecting block 220. The downwardly pressed connecting block 220 can ensure the stability of the fastening with the right plug buckle 320. At the same time, when the right plug edge buckle 330 moves, it will also slightly push the end of the upper pressure plate 210 where the pressure plate buckle 211 is fixed upward, so that the right plug edge buckle 330 can pass through the bottom end of the pressure plate buckle 211 and be fastened to the pressure plate buckle 211.

[0028] Specifically, in this utility model, the connecting plug 110, connecting hook 120, upper pressure plate 210 and connecting block 220 are all made of plastic material, so that they can all undergo a certain elastic deformation when connected, thereby facilitating the installation and disassembly of the left plug 100, the middle connecting socket 200 and the right plug 300.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
