Radio-frequency coaxial connector of push self-locking structure

Abstract

The invention provides a radio-frequency coaxial connector of a push self-locking structure. By the radio-frequency coaxial connector, pre-tightening force can be rapidly adjusted, and the connector is effectively prevented from loosening. The radio-frequency coaxial connector of the push self-locking structure comprises a male head, a female head, a locking sleeve and a spring, a clamping arm isarranged at an end part of the male head, a press head is arranged at an end part of the clamping arm, a clamping groove is formed in an outer side of the female head and is matched with the press head, the spring and the locking sleeve sequentially are arranged outside the male head in a sleeving manner in a radial direction from inside to outside, a step surface is arranged at an inner side of one end, near to the male head, of the locking sleeve, the radio-frequency coaxial connector is characterized by also comprising a limitation sleeve and an adjustment sleeve, the limitation sleeve is arranged outside the male head in a sleeving manner and is arranged between the male head and the locking sleeve, a guide convex block is arranged at an outer side of the limitation sleeve, the guide convex block extends to a guide groove in a side wall of the locking sleeve, the guide groove extends in an axial direction of the locking sleeve, the adjustment sleeve is arranged outside the male head by a thread, a flange is arranged at the adjustment sleeve and props against the limitation sleeve, and two ends of the spring elastically prop against the step surface of the locking sleeve and anend surface of the limitation sleeve correspondingly.

Description

technical field [0001] The invention relates to the field of radio frequency coaxial connectors, in particular to a radio frequency coaxial connector with a push-in self-locking structure. Background technique [0002] RF coaxial connectors are mainly used to realize the transfer and transmission of RF signals. Traditional RF coaxial connectors include male and female connectors. The male and female connectors are threaded, so quick assembly cannot be achieved. The RF coaxial connector of the company has added a clamp arm at the end of the male head. The end of the clamp arm is equipped with a pressure head, and the outer sleeve of the male head is provided with a locking sleeve. The locking sleeve and the male head are elastically connected. When the female head is inserted into the male head, a circle of clamp arms is set around the end of the female head, the locking sleeve is pushed to the outside of the indenter, and the locking sleeve is radially limited to press the i...

[0002] RF coaxial connectors are mainly used to realize the transfer and transmission of RF signals. Traditional RF coaxial connectors include male and female connectors. The male and female connectors are threaded, so quick assembly cannot be achieved. The RF coaxial connector of the company has added a clamp arm at the end of the male head. The end of the clamp arm is equipped with a pressure head, and the outer sleeve of the male head is provided with a locking sleeve. The locking sleeve and the male head are elastically connected. When the female head is inserted into the male head, a circle of clamp arms is set around the end of the female head, the locking sleeve is pushed to the outside of the indenter, and the locking sleeve is radially limited to press the indenter, so that the indenter is embedded in the outer side of the female head In the card slot and fix the female head

Although the existing radio frequency coaxial connector can realize the rapid assembly of the male and female connectors, the pretightening force cannot be adjusted and it is easy to loosen
