Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, specifically to a locking mechanism for a wire harness connector. Background Technology

[0002] Wire harness connectors, also known as plugs, are a type of terminal consisting of a plug and a socket. They are mainly used for wire harness connections in automotive circuits, serving as electrical relay stations between electrical devices. They are also used in instruments, office equipment, commercial machines, and other fields. They employ a locking device to ensure connection stability and prevent vibration from causing them to come loose. The locking device must be released before disassembly.

[0003] Traditional wire harness connector locking structures often employ a single snap-lock mechanism. Under prolonged exposure to vibration, the snap-lock is prone to fatigue deformation, leading to increased engagement gaps and eventual loosening, resulting in a high failure rate. Furthermore, when external force compresses the elastic snap-lock, it can deform and detach from the slot, causing unexpected separation of the plug and socket, resulting in low connection stability. Therefore, a new locking mechanism for wire harness connectors is proposed to address the aforementioned problems. Utility Model Content

[0004] To address the aforementioned technical problems, a locking mechanism for a wire harness connector is provided. This technical solution solves the problems of traditional wire harness connector locking structures mentioned in the background art, which mostly use a single snap-locking mechanism. When exposed to vibration for a long time, the snap-lock is prone to fatigue deformation, leading to an increased locking gap and eventual loosening, resulting in a high failure rate. Furthermore, when external force compresses the elastic snap-lock, the snap-lock is prone to deformation and detachment from the slot, causing the plug and socket to separate unexpectedly, resulting in low connection stability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A locking mechanism for a wire harness connector includes a plug and a socket. A first wire harness and a second wire harness are fixedly connected to opposite ends of the plug and socket, respectively. L-shaped elastic connecting rods are fixedly connected to both ends of the plug, and a fixing block is fixedly connected to the other end of each L-shaped elastic connecting rod. Fixing frames are fixedly connected to both ends of the socket. A connecting groove is formed at the end of each fixing frame near the L-shaped elastic connecting rod. A slot is formed through the opposite ends of both fixing frames. A sliding groove is formed through the opposite ends of both fixing frames near the second wire harness. A slider is slidably connected inside the sliding groove. A push block is fixedly connected to the end of the slider near the connecting groove and slidably connected inside the connecting groove. A locking tongue is fixedly connected to the end of the push block near the L-shaped elastic connecting rod.

[0007] Preferably, the fixing block is engaged inside the slot.

[0008] Preferably, the locking tongue abuts against the L-shaped elastic connecting rod.

[0009] Preferably, the inner top and inner bottom of the connecting groove are provided with multiple anti-slip grooves, and the upper and lower ends of the push block are fixedly connected with elastic blocks, which are engaged in the interior of the anti-slip grooves.

[0010] Preferably, a push plate is fixedly connected to the end of the slider away from the push block.

[0011] Preferably, the end of the push plate away from the fixed frame has anti-slip texture.

[0012] The advantages of this utility model compared with the prior art are:

[0013] This solution proposes a locking mechanism for wire harness connectors. Through a composite structure of initial engagement with an L-shaped rod and secondary tightening with a locking tongue, the fixing block can be stably engaged in the slot even under long-term vibration and impact conditions, reducing the risk of poor connector contact and ensuring stable equipment operation.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figures 1-5As shown, a locking mechanism for a wire harness connector includes a plug 1 and a socket 2. A first wire harness 3 and a second wire harness 4 are fixedly connected to the ends of the plug 1 and the socket 2 that are far apart from each other. L-shaped elastic connecting rods 5 are fixedly connected to both ends of the plug 1. A fixing block 6 is fixedly connected to the other end of the L-shaped elastic connecting rod 5. Fixing frames 7 are fixedly connected to both ends of the socket 2. A connecting groove 8 is opened at the end of the fixing frame 7 near the L-shaped elastic connecting rod 5. A slot 9 is opened through the ends of the two fixing frames 7 that are far apart from each other. A sliding groove 10 is opened through the side of the two fixing frames 7 that are far apart from each other and near the second wire harness 4. A slider 11 is slidably connected inside the sliding groove 10. A push block 12 is fixedly connected to the end of the slider 11 near the connecting groove 8. The push block 12 is slidably connected inside the connecting groove 8. A locking tongue 13 is fixedly connected to the end of the push block 12 near the L-shaped elastic connecting rod 5.

[0023] Furthermore, the fixing block 6 is engaged inside the slot 9.

[0024] Furthermore, the locking tongue 13 abuts against the L-shaped elastic connecting rod 5.

[0025] Furthermore, the L-shaped elastic connecting rod 5 has elastic deformation capability. When the plug 1 and socket 2 are connected, by squeezing the two L-shaped elastic connecting rods 5 inward, the fixing block 6 can be driven to retract inward. At this time, the L-shaped elastic connecting rod 5 and the fixing block 6 can be inserted into the connecting groove 8. As the L-shaped elastic connecting rod 5 is continuously inserted, the fixing block 6 goes deeper into the connecting groove 8. When the fixing block 6 is aligned with the groove 9, the fixing block 6 pops out and is locked into the groove 9 under the action of the elastic force of the L-shaped elastic connecting rod 5, realizing the initial locking of the connection between the plug 1 and socket 2.

[0026] Furthermore, multiple anti-slip grooves 16 are provided on the inner top and inner bottom of the connecting groove 8, and elastic blocks 15 are fixedly connected to the upper and lower ends of the push block 12, with the elastic blocks 15 engaging inside the anti-slip grooves 16.

[0027] Furthermore, a push plate 14 is fixedly connected to the end of the slider 11 away from the push block 12. When the elastic block 15 is engaged inside the anti-slip groove 16, the push plate 14 is pushed to move in the direction of the fixed block 6, which allows the slider 11 and the push block 12 to push the locking tongue 13 into the space between the L-shaped elastic connecting rod 5 and the socket 2, thereby locking the position of the fixed block 6 and preventing the fixed block 6 from retracting inward and separating from the groove 9 under external pressure, thus ensuring the stability of the connection.

[0028] Furthermore, the end of the push plate 14 away from the fixed frame 7 is provided with anti-slip texture 17, and the anti-slip groove 16 provides multiple positioning points for the elastic block 15. By sliding the push block 12, the elastic block 15 can be inserted into different anti-slip grooves 16, which can fix the push block 12 in different positions. When the push block 12 is stationary, the engagement between the elastic block 15 and the anti-slip groove 16 can prevent the push block 12 from sliding due to vibration. The anti-slip texture 17 can increase the friction between the operator's hand and the push plate 14, and prevent slippage during operation.

[0029] Working principle: During use, plug 1 is inserted into socket 2. During insertion, when the L-shaped elastic connecting rod 5 approaches the opening of the connecting groove 8, the two L-shaped elastic connecting rods 5 are pressed inward, which causes the fixing block 6 to retract inward. At this time, the L-shaped elastic connecting rod 5 and the fixing block 6 are inserted into the connecting groove 8. As the L-shaped elastic connecting rod 5 is continuously inserted, the fixing block 6 goes deeper into the connecting groove 8. When the fixing block 6 is aligned with the groove 9, the fixing block 6 pops out and locks into the groove 9 under the elastic force of the L-shaped elastic connecting rod 5, realizing the initial locking of the connection between plug 1 and socket 2. Then, push the push plate 14 to move in the direction of the fixing block 6, which allows the slider 11 and push block 12 to push the locking tongue 13 to insert between the L-shaped elastic connecting rod 5 and socket 2, locking the position of the fixing block 6 and preventing the fixing block 6 from retracting inward and separating from the groove 9 under external pressure, thus ensuring the stability of the connection.
