Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric connector, especially relates to a servo motor connector. BACKGROUND

[0002] In the field of industrial automation, servo motors are widely used in various high-precision and high-speed control scenarios. Whether on production lines or in mechanical equipment, servo motors play a crucial role. As an industrial connector designed specifically for servo systems, the power connector of a servo motor is mainly used for power connection of the servo motor, ensuring the normal operation of the entire servo system. As one of the important components of a servo motor, the servo motor connector is usually installed on the surface of the servo motor and uses a socket and plug-in method to achieve power access. The existing servo motor, considering the simultaneous transmission of power and signals, usually integrates power pins and signal pins on the socket and integrates power terminals and signal terminals on the plug, enabling stable power transmission in high-speed, high-load, and complex working environments.

[0003] With the market's demand for connectors to develop towards high performance, high density, and high frequency technology, connectors are required to not only meet basic functions but also have good waterproof, dustproof, and strong anti-interference functions in some humid and dusty environments to prevent water and dust from entering the connector and protect electronic components from damage. However, the current industrial servo motor connectors on the market have the following drawbacks: 1. The plug connector and the socket connector are fixed with screws, which is time-consuming and tedious to assemble and disassemble. The screws can easily loosen due to machine vibration or other external factors, affecting the connection stability between the plug connector and the socket connector. 2. There is a lack of design structure specifically for waterproof and oil-proof, and the waterproof and oil-proof performance is poor. Water or oil can easily penetrate into the connector, corrode the internal circuit components, cause short circuits or other electrical faults, and reduce the service life of the power connector. 3. The height of the connector is too high, directly affecting the overall size of the servo motor, causing the servo motor to be unable to install. Therefore, it is necessary to further improve and upgrade the existing servo motor connector to better meet the new market demand direction. UTILITY MODEL CONTENTS
