Connector locking and electromagnetic unlocking device

Abstract

The invention discloses a connector locking and electromagnetic unlocking device. The device is fixed in the connector and comprises a locking mechanism, an electromagnetic mechanism, a hand wheel mechanism and a labor saving mechanism, wherein the rear end of the electromagnetic mechanism is in axially relatively fixed and running fit connection with the hand wheel mechanism; the hand wheel mechanism and the locking mechanism are connected through thread fit; the locking mechanism is sleeved in the electromagnetic mechanism and is connected with the electromagnetic mechanism in a sliding fitmanner; and the labor saving mechanism is fixedly connected at the front end of the electromagnetic mechanism through a bolt and is sleeved at the outer periphery of the locking mechanism. Through the connector locking and electromagnetic unlocking device, an electromagnet triggers the labor saving mechanism and drives the connector locking mechanism to unlock, and fast unlocking separation of anelectromagnetic separation connector with multiple cores is realized. Meanwhile, when the hand wheel mechanism is rotated to drive the locking mechanism to move forward, the unlocking force of the labor saving mechanism is automatically stored to prepare for the next work cycle. The connector locking and electromagnetic unlocking device has the characteristics of compact structure, reliable locking and unlocking and high practicability.

Description

technical field [0001] The invention relates to a connector locking and electromagnetic unlocking device, belonging to the technical field of electrical connectors. Background technique [0002] The small electromagnetic unlocking separation connector is generally equipped with an electromagnet on the basis of the mechanical separation connector, and the electromagnetic attraction force after the electromagnet is energized replaces the external force to realize the electromagnetic unlocking and separation of the connector. As the number of separation connector cores increases, the spring force of the separation spring needs to be increased accordingly to overcome the increased total separation force. After the force is applied, the unlocking force acting on the unlocking lever (pull rod) of the separation device also increases correspondingly. In practical applications, due to the limitation of the volume and weight of the electromagnet by the connector, the resulting attrac...

Problems solved by technology

As the number of separation connector cores increases, the spring force of the separation spring needs to be increased accordingly to overcome the increased total separation force. After the force is applied, the unlocking force acting on the unlocking lever (pull rod) of the separation device also increases correspondingly. In practical applications, due to the limitation of the volume and weight of the electromagnet by the connector, the resulting attraction force is limited. When the unlocking force exceeds the attraction force After that, the connector cannot be unlocked and separated normally

To solve the problem that the connector cannot be unlocked and separated when there are multiple cores, it is necessary to add a labor-saving mechanism on the basis of the existing unlocking device, and use the attraction force of the electromagnet to trigger the labor-saving mechanism to generate an external force greater than the unlocking force. unlock separation
