The first nut is installed on the existing adapter, but when the adapter is connected with the connector, the firm contact between the connector and the adapter cannot be ensured.

SUMMERY OF THE UTILITY MODEL

An object of the present invention is to provide an adapter for a radio frequency connector to solve the problems of the prior art.

The utility model provides an adapter for radio frequency connector, includes adapter casing, inner conductor, connector, adapter casing and connector joint, and adapter casing one end is equipped with draw-in groove one, and connector one end is equipped with draw-in groove two, and when adapter casing and connector were connected, the one end that the connector was equipped with draw-in groove two was located draw-in groove one, adapter casing and connector junction cover are equipped with the sleeve, be connected with lock nut on the sleeve.

Furthermore, the outer wall of one end of the sleeve is provided with external threads, the other end of the sleeve is provided with a conical surface, one end of the locking nut is in threaded connection with the sleeve, and the inner side of the other end of the locking nut is provided with the conical surface.

Further, the taper of the conical surface of the locking nut is smaller than that of the conical surface of the sleeve.

Further, the outer wall of the connector is provided with a groove.

Furthermore, a plurality of bulges are arranged on the inner wall of the conical end of the sleeve and are positioned above the groove, and when the locking nut is screwed, the conical surface on the locking nut extrudes the conical surface on the sleeve to ensure that the bulges are positioned in the groove.

Further, the groove is an annular groove.

The beneficial effects of the utility model are that:

the sleeve is sleeved at the joint of the adapter and the connector, the locking nut is connected to the sleeve in a threaded manner, and when the locking nut is locked, the sleeve and the connector are tightly pressed, so that the adapter and the connector are in good contact, and the stability and reliability of the test are improved;

the axial direction and the radial direction of the connector are limited by the protrusions on the sleeve, and the connector and the adapter are guaranteed not to be loosened.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

FIG. 1 is a schematic cross-sectional view of the present invention;
