Description

Retaining Ring for Antenna Connector

technical field

The utility model relates to a fixed ring, in particular to a fixed ring used for an antenna connector.

Background technique

The antenna connector is mainly used to connect an external antenna to an internal circuit of an electronic device, such as a router, a set-top box, or a modem. Taking the connection to the router as an example, the external antenna is usually fixed on the router by means of screw-to-thread locking, and then electrically connected to the internal circuit of the router.

Please refer to FIG. 10 , which is a side view of an antenna 60 installed on a router 40 in the prior art. One end of an antenna connector 50 is connected to the antenna 60, and the other end of the antenna connector 50 is in a thread-to-lock manner. Take a positive tooth screw as an example, that is, rotate clockwise, and the antenna connector 50 Screw it against the outer surface of a housing 41 of the router 40 , or rotate it counterclockwise to loosen the antenna connector 50 . Therefore, by tightening or unscrewing the antenna connector 50 , the antenna 60 is assembled on the router 40 or the antenna 60 is disassembled from the router 40 .

In order to achieve better reception quality or aesthetic design, the size and weight of the external antenna usually need to be increased. In addition, when using the router 40 , the user will adjust the angle or position of the antenna 60 to increase the signal strength of the antenna 60 . However, when the user rotates the antenna 60 , if the direction of rotation is just to be tightened (clockwise), this will not affect the fixed installation of the antenna 60 on the router 40 . On the contrary, if the direction of rotation is just the direction of unscrewing (counterclockwise), and the torque of rotation is greater than the assembly strength of the screw teeth to the lock, the antenna 60 will be loosened, which will not only cause inconvenience for the user to operate the router 40, but also It directly affects the receiving quality of the antenna 60 .

Utility model content
