Description

Technical Field

[0001] This utility model relates to the field of detachment detection, specifically a device for detecting the detachment of wire terminals. Background Technology

[0002] Automotive wiring terminals are indispensable connection components in automotive electrical systems. They are typically composed of a metal conductor and an insulating shell, and come in various shapes, including sheet, round, and fork types. The metal conductor is responsible for the electrical connection, ensuring stable current transmission, while the insulating shell provides protection and fixation, preventing short circuits and other faults caused by contact between the conductor and the outside environment. Through processes such as crimping and welding, they are firmly connected to the wires to form a complete electrical connection unit.

[0003] During vehicle operation, the wire terminals play a crucial role. They serve as a bridge for signal transmission and power supply between various electrical devices in the vehicle. Whether it is the engine's ignition system, electronic control system, or in-vehicle entertainment equipment and lighting system, all rely on wire terminals for electrical connection. Their performance directly affects the stability and reliability of the vehicle's electrical system. Once a connection problem occurs, it may lead to the failure of vehicle components or even cause serious safety hazards.

[0004] Currently, the main method for detecting disconnection of automotive wiring terminals is the tensile test. The tensile test requires applying a certain amount of tension to the terminal and assessing the reliability of the connection by judging whether it has come loose. However, this method requires the testers to pull the wires one by one, which consumes a lot of the testers' time and energy. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a wire terminal detachment detection device to solve the technical problem that the method of detecting wire terminals detachment by manual pulling is inefficient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire terminal detachment detection device, comprising a detection platform, a plurality of grooves on the top of the detection platform, a detection plate installed at the top of the detection platform, a plurality of sliding blocks inside the detection plate, a spring installed on one side of each sliding block, a second fixing plate fixed to one end of each sliding block, a locking block fixed to the bottom of the second fixing plate, a first fixing plate on one side of each groove, a locking groove on the top of the first fixing plate, limit blocks fixed on both sides of the detection plate, a second limit post inside each limit block, movable posts fixed at both ends of each second limit post, a connecting plate connected to the end of each movable post, a hydraulic cylinder installed on the top of the connecting plate, a wire installed inside the groove, and a connector fixed to the end of each wire.

[0007] By adopting the above technical solution, the problem of low efficiency in detecting wire terminals by manual pulling is solved. When the detection plate covers the detection table, the squeezing plates inside the first and second fixing plates squeeze and fix the wires. Then the detection plate is pushed to one side. The detection plate moves by pushing the sliding block through the spring. The fixed wires are squeezed and contracted by the sliding block because the friction between the outer wall and the squeezing plate is greater than the spring's thrust. The unstable wires are pulled out from one side of the connector by the movement of the sliding block and the clamping of the first and second fixing plates.

[0008] The present invention is further configured such that a second support column is sleeved on the outer wall of the movable column, and the second support column is fixedly installed on the top of the testing table.

[0009] Preferably, the four sets of second support columns limit the movement of the detection plate through the second limiting columns, so that the detection plate can move up and down in the vertical direction.

[0010] The present invention is further configured such that a compression plate is provided inside the first fixing plate and the second fixing plate, and the compression plate is elastic.

[0011] Preferably, when the detection plate completely covers the top of the detection table, the extrusion plates inside the first and second fixing plates extrude and fix the wire, and the extrusion plates will undergo a certain deformation during the extrusion process, thereby reducing the damage to the wire caused by the extrusion.

[0012] The present invention is further configured such that the inner wall of the extrusion plate is provided with a plurality of protrusions, the protrusions being configured as arc-shaped.

[0013] Preferably, during the extrusion process, multiple sets of protrusions on the inner wall of the extrusion plate can increase the friction generated by the extrusion block extruding the wire.

[0014] The present invention is further configured such that four sets of first support columns are installed on the top of the testing platform, a first limiting column is fixed between two sets of first support columns, and a push plate is sleeved on the outer wall of the first limiting column.

[0015] Preferably, two sets of limiting posts limit the movement of the push plate, enabling the push plate to move horizontally.

[0016] The present invention is further configured such that the inner wall of the push plate is arc-shaped, and a handle is installed on the top of both the push plate and the detection plate.

[0017] Preferably, when the pusher plate moves, the arc-shaped inner wall of the pusher plate can push the wire located above the groove into the groove.

[0018] The present invention is further configured such that multiple sets of rollers are movably installed on the top of the testing platform, and the rollers are arranged between two sets of grooves.

[0019] Preferably, the roller can reduce friction between the wire and the top of the test stage, thereby facilitating the pusher plate to push the wire into the groove.

[0020] The present invention is further configured such that the sliding block is T-shaped, and the detection plate has a matching sliding groove inside.

[0021] Preferably, the sliding block is T-shaped, so that the detection plate can limit and control the sliding block during its movement and prevent the sliding block from slipping out of the detection plate.

[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of low efficiency in manually pulling to detect the detachment of wire terminals by setting up a testing platform, hydraulic cylinder, testing plate, spring, first fixed plate, second fixed plate, and sliding block. When the testing plate covers the testing platform, the extrusion plates inside the first and second fixed plates extrude and fix the wire. Then, the testing plate is pushed to one side. The testing plate moves the sliding block by the spring. The friction between the outer wall of the fixed wire and the extrusion plate is greater than the spring's thrust, causing the sliding block to compress and contract the spring. The unstable wire is pulled out from one side of the connector by the movement of the sliding block and the clamping of the first and second fixed plates.

[0023] 2. This utility model, by setting a push plate, a first limiting post, a first supporting post, and a roller, places the connector on one side of the top of the testing table, and then inserts multiple sets of wires into the bottom of the first limiting post. Subsequently, the operator pushes the push plate to one side using the handle. During the movement of the push plate, the arc-shaped wall on one side of the bottom of the push plate pushes the wires located on the top of the testing table into the groove. The roller can reduce the friction between the wires and the top of the testing table, thereby facilitating the push plate to push the wires into the groove. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Please see Figure 1 — Figure 6The system includes a testing platform 1, with multiple sets of grooves 101 on its top. A testing plate 4 is mounted on the top of the testing platform 1. Multiple sets of sliding blocks 401 are installed inside the testing plate 4. A spring 405 is mounted on one side of each sliding block 401. A second fixing plate 407 is fixed to one end of each sliding block 401. A locking block 408 is fixed to the bottom of the second fixing plate 407. A first fixing plate 402 is provided on one side of each groove 101. A locking groove 409 is opened on the top of the first fixing plate 402. Limiting blocks 406 are fixed on both sides of the testing plate 4. A second limiting post 303 is provided inside each limiting block 406. Moving posts 302 are fixed to both ends of each second limiting post 303. A connecting plate 301 is connected to the end of each moving post 302. A hydraulic cylinder 3 is mounted on the top of the connecting plate 301. A hydraulic cylinder 3 is installed inside the groove 101. There is a wire 601, and a connector 6 is fixed to the end of the wire 601. This solves the problem of low efficiency in detecting the wire terminals by manually pulling them. When the detection plate 4 covers the detection table 1, the squeezing plate 403 inside the first fixing plate 402 and the second fixing plate 407 squeezes and fixes the wire 601. Then the detection plate 4 is pushed to one side. The detection plate 4 moves the sliding block 401 by the spring 405. The fixed wire 601 has a greater friction between its outer wall and the squeezing plate 403 than the pushing force of the spring 405, so the sliding block 401 squeezes and contracts the spring 405. The unstable wire 601 is pulled out from one side of the connector 6 by the movement of the sliding block 401 and the clamping of the first fixing plate 402 and the second fixing plate 407.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The outer wall of the movable column 302 is fitted with a second support column 304, and the second support column 304 is fixedly installed on the top of the detection table 1. The four sets of second support columns 304 limit the movement of the detection plate 4 through the second limit column 303, so that the detection plate 4 can move up and down in the vertical direction.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The first fixing plate 402 and the second fixing plate 407 are provided with a pressing plate 403 inside, and the pressing plate 403 is elastic. When the detection plate 4 completely covers the top of the detection table 1, the pressing plate 403 inside the first fixing plate 402 and the second fixing plate 407 presses and fixes the wire 601. The pressing plate 403 will generate a certain deformation during the pressing of the wire 601, thereby reducing the damage to the wire 601 caused by the pressing plate 403.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 6The inner wall of the extrusion plate 403 is equipped with multiple sets of protrusions 404, which are arc-shaped. During the process of the extrusion plate 403 extruding the wire 601, the multiple sets of protrusions 404 on the inner wall of the extrusion plate 403 can increase the friction generated by the extrusion plate 403 extruding the wire 601.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 Four sets of first support columns 202 are installed on the top of the testing platform 1. A first limiting column 201 is fixed between two sets of first support columns 202. A push plate 2 is sleeved on the outer wall of the first limiting column 201. The two sets of limiting columns 201 limit the movement of the push plate 2, so that the push plate 2 can move along the horizontal direction.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The inner wall of the push plate 2 is set to be arc-shaped. Both the push plate 2 and the detection plate 4 are equipped with handles 5. When the push plate 2 moves, the arc-shaped inner wall of the push plate 2 can push the wire 601 located above the groove 101 into the groove 101.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 Multiple sets of rollers 102 are movably installed on the top of the testing table 1, and the rollers 102 are positioned between two sets of grooves 101. The rollers 102 can reduce the friction between the wire 601 and the top of the testing table 1, thereby facilitating the pusher plate 2 to push the wire 601 into the groove 101.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The sliding block 401 is T-shaped, and the detection plate 4 has a matching sliding groove inside. The T-shaped sliding block 401 allows the detection plate 4 to limit and control the sliding block 401 during movement, and prevents the sliding block 401 from slipping out of the detection plate 4.

[0036] In practical operation, the connector 6 is first placed on one side of the top of the testing platform 1. Then, multiple sets of wires 601 are inserted into the bottom of the first limiting post 201. Subsequently, the operator pushes the push plate 2 to one side using the handle 5. During the movement of the push plate 2, the arc-shaped wall on one side of the bottom of the push plate 2 pushes the wires 601 located on the top of the testing platform 1 into the groove 101. Then, the hydraulic cylinder 3 pushes the connecting plate 301 downward. The connecting plate 301, through the four sets of moving posts 302 connected to its bottom, pushes the two sets of second limiting posts 303 downward, so that the second limiting posts 303 push the testing plate 4 above the testing platform 1. When the contact plate 4 covers the testing platform 1, the locking block at the bottom of the second fixing plate 407... 408 is embedded in the slot 409 inside the first fixing plate 402, and the extrusion plate 403 inside the first fixing plate 402 and the second fixing plate 407 extrudes and fixes the wire 601. Then, the operator pushes the detection plate 4 to one side through the handle 5. During the movement of the detection plate 4, the detection plate 4 moves the sliding block 401 through the spring 405. The fixed wire 601 is connected because the friction between its outer wall and the extrusion plate 403 is greater than the pushing force of the spring 405, so the sliding block 401 extrudes and contracts the spring 405. The unstable wire 601 is pulled out from one side of the connector 6 by the movement of the sliding block 401 through the clamping of the first fixing plate 402 and the second fixing plate 407.
