Radio frequency coaxial electric coupler with quick-locking device

Abstract

The invention provides a radio frequency coaxial electric coupler with a quick-locking device. The quick-locking device comprises a plug quick-locking device and a socket quick-locking device. The back of an elastic jack catch (16) of the plug quick-licking device is fixed on the plug outer conductor (11). The front portion of the elastic jack catch (16) extends with a snap joint (161). A cone face of the snap joint (1611) is arranged on the front lateral surface of the snap joint (161). The cone face of the snap joint (1611) of the elastic jack catch (16) enables the snap joint (161) to contract inward along the radial direction under the effect of the external force. The periphery of the elastic jack catch (16) is provided with a columnar-shaped unlocking sleeve (15). The plug quick-locking device refers to that a block groove (222) is formed on the front end of an outer conductor (22) of the plug along the axial direction. A catching groove (223) is formed radially outward on the wall of the block groove (222). The quick-locking device of the electric coupler has the advantages of being simple in structure, quick in product assembling, and saving the production cost of the quick-locking device.

Description

technical field [0001] The present invention relates to the technical field of radio frequency coaxial connectors, in particular to a radio frequency coaxial electrical connector with a quick lock device, especially to passive intermodulation and impedance matching of a radio frequency coaxial electrical connector with a quick lock device well sealed. Background technique [0002] At present, a large number of high-power RF coaxial connectors are used in the communication industry. Due to their large size and high passive intermodulation index, high-power RF coaxial connectors generally adopt the connection method of screw locking. Although thread locking is reliable in connection, it has the following defects: it cannot realize quick insertion and removal, low assembly efficiency, and a certain installation space must be left between connectors to facilitate the use of nut loading and unloading tools, and it is difficult to achieve high density Install. In view of the pro...

Although thread locking is reliable in connection, it has the following defects: it cannot realize quick insertion and removal, low assembly efficiency, and a certain installation space must be left between connectors to facilitate the use of nut loading and unloading tools, and it is difficult to achieve high density Install

Although this connection structure can realize fast locking and separation between two connection units, it is only limited to low-power signal transmission
