Description

A full escapement push-pull radio frequency coaxial connector

technical field

The utility model relates to the technical field of communication connectors, in particular to a full escapement push-pull radio frequency coaxial connector.

Background technique

The existing radio frequency connector includes a plug and a socket. The plug has an inner conductor of the plug that can be inserted into the inner conductor of the socket, and the plug also has an outer conductor of the plug that can be inserted into the socket shell. In some cases, it is necessary to ensure that the plug cannot Loosening, the anti-loosening structure of the existing RF connectors is generally realized by threaded connection, and the operation is cumbersome.

Utility model content

The purpose of the utility model is to provide a full-escapement push-pull radio frequency coaxial connector which is axially locked after the plug and the socket are mated, and which is easy to unlock.

The technical scheme of the utility model is: a full escapement push-pull radio frequency coaxial connector, which is composed of a plug and a socket. The inner conductor of the socket is mated with the inner conductor, and the outer part of the socket is a socket housing that can accommodate the insertion of the outer conductor of the plug. There is a socket insulator and a contact head that is mated with the outer conductor of the plug between the socket housing and the inner conductor of the socket. On the outer ring of the outer conductor, there is a connecting shell that can be inserted into the socket shell. The front part of the connecting shell is provided with a claw-shaped expansion and contraction structure and an outward protrusion at the front end. The valgus edge snaps into the matching concave structure; the front end of the outer conductor of the plug is provided with an valgus edge structure that can be axially stopped by the front end of the connecting shell.

The valgus protrusions provided at the front end of the connection housing are a plurality of bosses distributed along the circumference, and the concave structure on the inner wall of the socket housing is an annular groove matching with the bosses.

The claw-shaped expansion-contraction structure connecting the front part of the housing is a plurality of axial through-slits distributed along the circumference.

A protruding portion is provided on the mating surface of the contact head end of the socket that is mated with the outer conductor of the plug.

The utility model has no axial movement gap after the plug and the socket are mated, which improves the radio frequency performance of the product, and the plugging and operation are faster and time-saving; after the plug and the socket are mated, the connecting shell of the plug and the socket shell are locked Tight fit, when the cable is subjected to external force, the valgus of the front end of the outer conductor of the plug will stop along the axial direction of the front end of the connected shell, and the plug will not fall off from the socket. When the plug and socket need to be separated, the unlocking mechanism on the plug needs to be pulled ——The separation function can only be realized by connecting the shell, which is simple and convenient to operate. This prevents the plug from accidentally falling out of the socket, increasing the reliability and safety of the connection.

Detailed ways

As shown in Figures 1 to 3, the utility model is composed of a plug 1 and a socket 2. The plug 1 has a coaxial plug inner conductor 4, a plug insulator 8 and a socket outer conductor 3, and the outer ring of the plug outer conductor 3 is movable. The sleeve is equipped with a connection shell 5, the front end of the connection shell 5 is provided with an everted boss 6, and the front part of the wall of the connection shell 5 is provided with a plurality of axial through slits 13 so that the boss 6 can be elastically deformed, and the outer conductor 3 of the socket The front end is fitted with a retaining ring 7 whose outer diameter is larger than the outer diameter of the boss 6 in front of the boss 6 . Therefore, after the plug 1 is plugged into the socket 2, the retaining ring 7 of the outer conductor 3 of the socket can be stopped by the boss 6 from behind to realize an axial stop. The inside of the socket 2 is provided with a socket inner conductor 11 that can accommodate the plug inner conductor 4 to be inserted. The end of the socket inner conductor 11 is provided with an inward edge to ensure reliable contact with the plug inner conductor 3 . In the socket 2, the external socket 2 is inserted into the socket shell 9 with the connecting shell 5 of the plug 1 that can accommodate it. The inner wall of the socket shell 9 is provided with an annular groove 13 for the boss 6 at the front end of the connecting shell 5 to snap into and cooperate with. The socket 2 is inserted into the socket. Between the shell 9 and the socket insulator 10, there is also a contact 12 that can be inserted into the plug outer conductor 3, and the plug-in mating surface on the end of the contact 12 is provided with an everted convex portion to ensure that it is compatible with the plug outer conductor 3. reliable contact.
