Description

Technical Field

[0001] This utility model relates to a fixing structure for motor cables, specifically a fixing structure for motor cables that move online. Background Technology

[0002] When a motor drive system is retrofitted with a mobile base-type permanent magnet speed controller for speed regulation and energy saving, the coupling magnetic field between the conductor rotor and the permanent magnet rotor of the permanent magnet speed controller needs to be changed by adjusting the axial position of the motor, thereby realizing the speed regulation function of the permanent magnet speed controller. For the motor, the original wiring position is fixed, and the power cable is not equipped with a clamping device. Axial movement of the motor may cause problems such as loosening, wear, and cable detachment at the cable connection points, affecting the reliability of the entire system. Summary of the Invention

[0003] The purpose of this invention is to address the problem of loosening, wear, and detachment of the power supply cable caused by frequent axial movement of the motor in practical applications of existing online mobile motors, and to provide a cable fixing structure that is highly feasible and applicable.

[0004] The objective of this utility model is achieved through the following technical solution: A motor cable clamping device includes a junction box clamp, a mounting base A, a cable clamp, a mounting base B, and a connecting plate; characterized in that: the junction box clamp is disposed on the mounting base A, the cable clamp is disposed on the mounting base B, and the mounting base A and the mounting base B are fixedly connected by the connecting plate; in use, the junction box clamp clamps the inlet of the motor junction box, and the cable clamp clamps the power cable of the motor connected to the junction box, thereby fixing the power cable to the junction box.

[0005] The junction box clamp includes a fixed half-ring A and a movable half-ring A. The fixed half-ring A and the movable half-ring A are connected by bolts to form a cylindrical space, and there is a gap between the fixed half-ring A and the movable half-ring A. The gap is adjusted by connecting bolts to adapt to the size of the inlet of the motor junction box.

[0006] The cable clamp includes a fixed half-ring B and a movable half-ring B. The fixed half-ring B and the movable half-ring B are connected by bolts to form a cylindrical space, and there is a gap between the fixed half-ring B and the movable half-ring B. The gap is adjusted by connecting bolts to accommodate the thickness of the motor power cable.

[0007] The mounting base A and the connecting plate are fixedly connected by bolts. The connecting plate has a fan-shaped hole, through which the bolt passes and is fixed to the mounting base A. The position of the bolt on the fan-shaped hole can be adjusted to accommodate the installation angle of the connecting plate.

[0008] The fixed connection between the mounting base B and the connecting plate includes, but is not limited to, bolt connection and welding.

[0009] This utility model has the following advantages: No modifications are required to the original motor's junction box.

[0010] It can accommodate junction boxes and power cables of different sizes and different cable entry angles.

[0011] When the motor moves online, it can move synchronously with the power cable. The motor cable clamping device of this utility model overcomes the resistance of the cable during the movement, keeping the cable joint and the motor terminal relatively stationary, and preventing the connection from loosening due to force.
