Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a communication connector with strong sealing performance. Background Art

[0002] A communication connector is a type of connector, also known as a plug, socket, or electrical connector in China. Generally, it refers to an electrical connector, which is a device that connects two active devices and transmits current or signals. It is widely used in military systems such as aviation, aerospace, and national defense. That is, a device that connects two active devices and transmits current or signals. A communication connector belongs to a network transmission medium interconnection device, and the performance of the connector used may affect the entire communication system. There are many models and standards for communication connector products, mainly including fiber optic connectors and electrical connection devices.

[0003] For example, Chinese Patent No. CN220272877U discloses a communication connector, which includes a male connector and a female connector.

A first terminal is provided on the female connector, a compression spring is sleeved on the outer wall of the first terminal, a support piece is installed at one end of the compression spring, the support piece is installed on the outer wall of the first terminal, an external thread sleeve is installed at the other end of the compression spring, the external thread sleeve is slidably installed on the first terminal, and several balls are slidably installed on the outer wall of the female connector. One end of the ball is adapted to the external thread sleeve. In the utility model, through the arrangement of the compression spring, the support piece, the external thread sleeve, and the ball, the elastic force of the compression spring pushes the external thread sleeve to squeeze the ball against the male connector, so that the male connector can be stably inserted into the female connector, and the installation is convenient, thereby improving the connection stability of the communication connector;

[0004] However, in the actual application process of this solution, after the male connector and the female connector are connected, it is impossible to seal between the male connector and the female connector.
