The utility model relates to the technical field of wires and cables, and specifically provides a servo motor connection cable that uses reinforcing ribs to increase strength and has good pressure resistance.

[0004] However, in actual use, the cable can only move up and down the limit spring. When squeezed to the side of the cable, the cable as a whole will not contact the limit spring. The overall compression resistance of the cable is poor, and thus the overall compression resistance of the cable is incomplete. Therefore, it has become an urgent problem to be solved to perfect and improve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a connecting cable for a servo motor to solve the problem that the cable proposed in the above-mentioned background technology can only be displaced up and down the limit spring, and when squeezed to the side of the cable, the entire cable will not contact the limit spring, the overall compression resistance of the cable is poor, and thus the overall compression resistance of the cable is incomplete.

[0006] To achieve the above object, the utility model provides the following technical solutions: a connection cable for a servo motor, comprising a wear-resistant protective layer, an inner side wall of the wear-resistant protective layer is provided with a mounting sleeve, an inner side wall of the mounting sleeve is provided with a fastening layer, a reinforcing rib is provided inside the fastening layer, a first movable cylinder is fixedly connected to the outer surface of the reinforcing rib, and a first moving rod is provided inside the first movable cylinder;

[0014] 1. The connecting cable for the servo motor is provided with a wear-resistant protective layer, an installation jacket, a fastening layer, a reinforcing rib, a first cable drum, a side elastic pad, a second cable drum, an extrusion block and an elastic column. When in use, the wear-resistant protective layer and the installation jacket can provide overall protection for the internal cable, so that the overall protection effect is good. At the same time, the cable will be installed inside the first cable drum, and the installation is relatively stable. The design of the side elastic pad and the extrusion block can ensure the side compression resistance of the cable. After the side elastic pad is squeezed, the extrusion block is squeezed, thereby applying a certain force to the reinforcing rib. At the same time, the design of the elastic column and the stabilizing ring can also resist the pressure of the cable. When squeezed from above the side elastic pad, the side elastic pad and the extrusion block cooperate with each other to achieve a good compression resistance effect, which reflects the practicality of the design.

When in use, the first cable reel and the second cable reel have the same structure, and side elastic pads are provided between two adjacent groups of first cable reels and second cable reels, so that the overall installation effect is better. Subsequently, when the first cable reel is squeezed downward, the first cable reel will drive the top ring and the first movement rod to move downward, thereby driving the resistance spring and the telescopic rod to move downward, so that the overall pressure resistance effect is better. When the first cable reel is not squeezed, it can automatically rebound through the resistance spring and the telescopic rod, which reflects the functionality of the design.
