Description

Technical Field

[0001] The utility model belongs to the technical field of servo motor connectors, and in particular relates to an integrated servo motor connector. Background Art

[0002] Servo motors are mainly used for high-precision position control. This type of motor converts electrical energy into mechanical energy through digital control to achieve precise positioning. Its displacement is controlled by the number of pulse signals, while the speed is determined by the pulse frequency. In actual applications, the PLC (Programmable Logic Controller) sends out pulses to drive the servo motor through the servo driver. At the same time, the encoder behind the motor will feedback the motor's stroke and compare it with the pulse sent by the PLC to form a closed-loop system to ensure precise position control. As an external interface connector, it is usually installed on the surface of the servo motor, and the external plug is inserted into the connector to integrate the external plug with the connector. The servo motor is powered by the external plug inserted into the connector.

[0003] When using the existing servo motor connector, the external plug is inserted into the connector in the connector, and the multiple pins in the connector are inserted into the plug to connect the plug to the connector. However, after long-term use, the pins in the connector are easily deformed or damaged when the plug is plugged in or out, which will affect the connection stability and effect between the external plug and the connector in subsequent use, thereby reducing the performance of the connector. For this reason, we propose an integrated servo motor connector. Utility Model Content
