Description

A visual fast thread-locking structure Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a visual quick-locking structure. Background Technology

[0002] In the field of electrical connections, the wire locking terminal is a core component for fixing and conducting cables, and its reliability directly affects the safe operation of equipment.

[0003] Traditional vertical 90-degree wire-locking terminals have significant drawbacks in practical applications, primarily in terms of ease of operation and visibility. Firstly, the operation relies on tools, requiring repeated loosening of the locking screws with a screwdriver to insert and remove the wires. This not only increases operation time but also increases the risk of improper installation or stripped screws in densely packed wiring environments due to limited tool movement space. Secondly, because the locking port is designed at a 90-degree angle perpendicular to the base plate, the operator's line of sight is perpendicular to the wire insertion direction, making it impossible to directly observe the wire insertion depth and crimping status. The operator can only judge the tightness based on experience, and this blind spot easily leads to safety hazards such as loose connections, increased contact resistance, or even wire detachment.

[0004] To address the aforementioned problems, this invention proposes a visual, rapid wire-locking structure. Summary of the Invention

[0007] The present invention is further configured such that a movable groove is provided on the side wall of the locking port, the limiting plate is slidably installed in the movable groove, and springs are fixedly connected to both sides of the inside of the movable groove, and the other end of the springs is fixedly connected to the limiting plate.

[0008] The present invention is further configured such that the linkage component includes a connecting seat, a connecting plate, and a fixed shaft; the connecting seat is fixedly installed on one end of the limiting plate away from the fixed plate, the connecting plate is rotatably connected to the connecting seat, the other end of the connecting plate is fixedly connected to the bottom end of the pressure rod, the locking seat has a movable groove inside, the connecting plate is rotatably disposed inside the movable groove, the locking seat has a fixed shaft fixedly installed inside, and the connecting plate and the fixed shaft are slidably engaged.

[0009] The present invention is further configured such that a groove is provided on the connecting plate, and the fixed shaft is slidably connected to the inside of the groove.

[0010] The present invention is further configured such that the wiring assembly includes a U-shaped wiring plate, wiring springs and wires; the U-shaped wiring plate is fixedly installed inside the groove, wiring springs are fixedly connected to both sides inside the U-shaped wiring plate, and a wire is fixedly connected to the bottom end of the U-shaped wiring plate, the wire extending to the outside of the locking seat.

[0012] The present invention is further configured such that multiple locking seats are arranged in a row.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This visualized, quick-connect cable locking structure comprises a pressure rod, connecting plate, fixed shaft, connecting seat, limiting plate, spring, fixing plate, and connector spring. Its operation is as follows: pressing down the pressure rod causes the limiting plate to move backward, widening the gap, allowing the cable to be inserted and deforming the connector spring to conduct electricity. Releasing the pressure rod releases the spring, which pushes the limiting plate back to clamp the cable. This enables tool-free, quick, one-handed operation. The 45° angled cable locking port allows the operator to visually observe the cable insertion depth, contact status, and clamping condition, improving wiring efficiency and ensuring connection reliability through its visualized design. It effectively addresses common problems in traditional vertical cable locking ports, such as loose connections and misoperations. Attached Figure Description

[0023] Please refer to Figures 1-3. This utility model provides a technical solution: a visual fast wire locking structure, including a wire locking base 1, wherein multiple wire locking bases 1 are arranged in a row.

[0024] The front panel of the wire locking base 1 is inclined at 45°. A wire locking port 2 is provided on the front panel of the wire locking base 1. A groove 3 is provided on the bottom side of the inside of the wire locking port 2. A wiring assembly is provided inside the groove 3. The wiring assembly includes a U-shaped terminal block 14, a terminal spring 15, and a wire 16. The U-shaped terminal block 14 is fixedly installed inside the groove 3. Terminal springs 15 are fixedly connected to both sides of the inside of the U-shaped terminal block 14. A wire 16 is fixedly connected to the bottom end of the U-shaped terminal block 14 and extends to the outside of the wire locking base 1.

[0025] A fixing plate 4 is fixedly installed on the inner wall of the locking port 2. A limiting plate 5 is slidably provided on one side of the inner wall of the locking port 2 corresponding to the fixing plate 4. The fixing plate 4 and the limiting plate 5 are arranged opposite to each other. Anti-slip pads are provided on the opposite ends of the fixing plate 4 and the limiting plate 5. The clamping surface formed by the fixing plate 4 and the limiting plate 5 applies uniform pressure to the cable, which ensures sufficient holding force and avoids damage to the cable insulation layer.

[0026] A movable groove 7 is provided on the side wall of the locking port 2. The limiting plate 5 is slidably installed in the movable groove 7. Springs 8 are fixedly connected to both sides of the inside of the movable groove 7. The other end of the springs 8 is fixedly connected to the limiting plate 5.

[0027] A pressure rod 6 is slidably inserted into the top of the locking seat 1. The pressure rod 6 is connected to the limiting plate 5 via a linkage assembly. The linkage assembly includes a connecting seat 9, a connecting plate 10, and a fixed shaft 11. The connecting seat 9 is fixedly installed on one end of the limiting plate 5 away from the fixed plate 4. The connecting plate 10 is rotatably connected to the connecting seat 9. The other end of the connecting plate 10 is fixedly connected to the bottom end of the pressure rod 6. A movable groove 12 is provided inside the locking seat 1. The connecting plate 10 is rotatably disposed inside the movable groove 12. The fixed shaft 11 is fixedly installed inside the locking seat 1. The connecting plate 10 and the fixed shaft 11 are slidably engaged. Specifically, a sliding groove 13 is provided on the connecting plate 10. The fixed shaft 11 is slidably connected to the sliding groove 13. The sliding groove 13 on the connecting plate 10 and the fixed shaft 11 form a sliding pair connection. This engagement method ensures the accuracy of the motion trajectory and provides the necessary degrees of freedom for the mechanism. When the pressure rod 6 is pressed down, the connecting plate 10 rotates controllably around the fixed shaft 11. At the same time, the relative sliding between the slide groove 13 and the fixed shaft 11 effectively adjusts the rotation radius, making the movement more stable and reliable.

[0028] Working principle:

[0029] During operation, the operator applies vertical downward pressure to the pressure rod 6, which moves smoothly downward along the axial direction, driving the connecting plate 10 to move through mechanical linkage. The sliding groove 13 on the connecting plate 10 forms a sliding pair connection with the fixed shaft 11. This cooperation method ensures the accuracy of the motion trajectory and provides the necessary degrees of freedom for the mechanism. When the pressure rod 6 is pressed down, the connecting plate 10 rotates controllably around the fixed shaft 11. At the same time, the relative sliding between the sliding groove 13 and the fixed shaft 11 effectively adjusts the rotation radius, making the movement more stable and reliable. This action is precisely transmitted to the limiting plate 5 through the connecting seat 9, driving the limiting plate 5 to slide stably along a predetermined path within the moving groove 7. The guiding effect of the moving groove 7 ensures the linearity of the movement of the limiting plate 5, while the spring 8 is uniformly compressed during the movement of the limiting plate 5, storing the necessary elastic potential energy. As the limiting plate 5 moves, the gap between it and the fixed plate 4 gradually widens, providing an accurate insertion channel for the cable plug.

[0030] The operator can then smoothly insert the cable plug along the 45° inclined locking slot 2. The cable first passes through the guide area formed by the fixing plate 4 and the limiting plate 5, and then precisely enters the groove 3. The symmetrically arranged connector springs 15 in the groove 3 produce coordinated elastic deformation when the cable is inserted. This deformation provides progressive insertion resistance and ensures accurate alignment of the cable connector through its unique V-shaped structure. The elastic deformation of the connector springs 15 not only achieves the initial positioning of the cable, but more importantly, it forms multiple reliable contacts with the cable through its contact surface, ensuring low-resistance conduction between the conductor 16 and the cable.

[0031] After cable insertion, the operator releases the pressure lever 6, and the energy stored in the spring 8 is smoothly released, pushing the limiting plate 5 back to its original position along the moving groove 7. During the reset process, the clamping surface formed by the fixed plate 4 and the limiting plate 5 applies uniform pressure to the cable, ensuring sufficient holding force while avoiding damage to the cable insulation layer. Throughout the operation, the unique 45° angled design of the locking port 2 provides the operator with an optimal viewing angle, making the cable insertion depth, the deformation state of the connector spring 15, and the movement of the clamping mechanism clearly visible, achieving true visual operation. This improves operational convenience, ensures connection reliability, and effectively avoids the blind spot problem of traditional vertical locking ports.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
