Description

Technical Field

[0001] This utility model relates to the field of wire connection technology, and in particular to a universal connection device for preventing wire loosening. Background Technology

[0002] In existing wire connection technologies, traditional connection devices commonly suffer from the problem of wires easily loosening. For example, common clamp-type connection devices rely solely on simple mechanical clamping to secure the wires. This type of device is not secure enough, and the clamping force easily weakens over time or under vibration, leading to wire loosening. This can then cause problems such as poor electrical connections and signal transmission interruptions, affecting the normal operation of equipment. In addition, traditional bolt-press connection devices require tightening bolts to secure the wires, but these bolts are also prone to loosening under repeated disassembly and assembly or vibration conditions, reducing the reliability of the connection.

[0003] Furthermore, some existing wire connection devices have poor versatility, typically only compatible with specific wire specifications. When connecting wires of different specifications or types, it is often necessary to replace the entire connection device or use additional adapter components. This not only increases costs but also reduces work efficiency, causing numerous inconveniences for actual installation and maintenance. Utility Model Content

[0007] According to the universal anti-loosening connection device for wires, a row of lower saw teeth is provided on the side wall of the fixing block near the top block, and a row of upper saw teeth is provided on the side wall of the top block near the fixing block. The upper and lower saw teeth cooperate with each other, and the cooperation between the upper and lower saw teeth can realize the self-locking function of the fixing block and the top block.

[0008] According to the universal anti-loosening connection device for wires, the left and right sides of the universal main clamp are threaded with second screws. Each second screw cooperates with a fixing block, and the second screw can hold the fixing block in place, thereby adjusting the distance between the saw teeth and the lower saw teeth.

[0009] According to the universal connection device for preventing loosening of wires, each of the first screws cooperates with the top block. By rotating the first screw, the top block can be moved, thereby fixing the wire through one end of the top block.

[0010] According to the universal anti-loosening connection device for wires, the side walls of the side cover, the upper outer shell, and the lower outer shell are fixedly connected with wire half-frames. The wire half-frames of the side cover and the upper outer shell form a hollow column structure. The wire half-frames of the side cover and the lower outer shell form a hollow column structure. The universal main clamp is provided with two wire grooves inside. Each wire groove is aligned with the wire half-frame. The wire passes through the guide half-frame, the guide groove, and the guide half-frame in sequence.

[0011] According to the universal connection device for preventing loosening of wires, each of the fixed half-frames is provided with a limiting groove inside, and the fixed half-frame is movably connected to a bottom cover through the limiting groove, and the bottom cover wraps the first screw inside.

[0012] According to the universal anti-loosening connection device for wires, a spring is provided between the top block and the fixed block, so that there is an elastic thrust between the top block and the fixed block, further preventing the two from loosening.

[0013] According to the universal anti-loosening connection device for wires, a limiting protrusion is provided on one side of the fixing block, and the limiting protrusion cooperates with the first limiting groove to prevent the fixing block from becoming loose.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, this practical device incorporates a spring between the top block and the fixed block. The elastic force of the spring ensures a tight contact between the top block and the fixed block, effectively preventing loosening and thus ensuring the stability of the wire connection. The upper and lower serrations cooperate to achieve a self-locking function between the fixed block and the top block, further enhancing the device's anti-loosening capability. Even under vibration or frequent plugging and unplugging conditions, the wire is not easily loosened, ensuring the reliability of the electrical connection.

Each second screw 6 cooperates with a fixing block 4. The second screw 6 can hold the fixing block 4 in place, thereby adjusting the distance between the saw teeth and the lower saw teeth.

[0027] The general-purpose main clamp 3 has two grooves inside, each groove having a first limiting groove 301 and a second limiting groove 302. The general-purpose main clamp 3 is equipped with two fixing blocks 4 through the two first limiting grooves 301. The general-purpose main clamp 3 is slidably connected to two top blocks 2 through the two second limiting grooves 302. The fixing block 4 has a row of lower serrations on its side wall near the top block 2, and the top block 2 has a row of upper serrations on its side wall near the fixing block 4. The upper and lower serrations cooperate to achieve the self-locking function between the fixing block 4 and the top block 2. A spring 11 is provided between the top block 2 and the fixing block 4 to provide elastic thrust between them, further preventing them from loosening.

[0028] The side cover 10, the upper outer shell 8 and the lower outer shell 9 are fixedly connected to the side walls of the wire half frame 901. The wire half frame 901 of the side cover 101 and the upper outer shell 8 form a hollow column structure. The general main clamp 3 is provided with two wire grooves 303 inside. Each wire groove 303 is aligned with the wire half frame 901. The wire passes through the guide half frame 901, the guide groove 303 and the guide half frame 901 in sequence. Each fixed half frame 902 is provided with a limiting groove inside. The fixed half frame 902 is movably connected to the bottom cover 7 through the limiting groove.
