Problems solved by technology

However, because the threaded connection mechanism needs to be tightened with a wrench, the arrangement density of the products of the threaded connection mechanism on the equipment panel is greatly limited, and the connection speed of the products of the threaded connection mechanism when separating and locking the products is 1 the slowest
On the contrary, the push-in connection mechanism is the fastest connection and occupies a small space, but the disadvantage is that the connection is not fast enough, the end pressure is insufficient, and the applicable environment is limited

Embodiment 1

[0032] Embodiment one: see Figure 1~5 As shown, a radio frequency coaxial connection mechanism includes a socket and a plug. The plug includes a base body 1, a cable core 2 located in the center of the cavity of the base body 1, a female terminal contact seat 3 located at the front end of the cable core 2, and a The cable sleeve 4 outside the cable core 2, the socket includes a connector body 5, a cable chamber 6 located in the center of the connector body 5, a male contact 7 located at the front end of the cable chamber 6, and the outer sleeve of the plug base 1 A shaft sleeve 8 is provided, the outer sliding sleeve of the shaft sleeve 8 near the cable end has a nut sleeve 9, the front end of the nut sleeve 9 is connected with the base body thread 10, and the tail end of the nut sleeve 9 is resisted by an elastic washer 11. On the boss on the outer edge of the shaft sleeve 8, the base body 1 is provided with an annular elastic flap 12 on the side corresponding to the inserti...

Embodiment 2

[0038] Embodiment two: if Figure 6 As shown, a radio frequency coaxial connection mechanism, in this embodiment, its structure is basically similar to that of Embodiment 1, the difference is that: on the annular elastic flap 12, the protruding end of the inner protrusion 13 is a conical surface , on the joint body 5 , the inner surface 17 of the annular convex portion 16 that engages with the tapered surface of the inner convex portion 13 forms a right-angled surface.

Embodiment 3

[0039] Embodiment three: as Figure 7 As shown, a radio frequency coaxial connection mechanism, in this embodiment, its structure is basically similar to that of Embodiment 1, the difference is that: on the annular elastic flap 12, the protruding end of the inner protrusion 13 forms a right angle surface , on the joint body 5 , the inner surface 17 of the annular convex portion 16 that engages with the tapered surface of the inner convex portion 13 is an inclined surface.

Abstract

The invention discloses a radio frequency coaxial connecting mechanism which comprises a socket and a plug; the radio frequency coaxial connecting mechanism is characterized in that a shaft sleeve is sleeved outside a base of the plug; a nut sleeve is sleeved at the outer side of one end of the shaft sleeve close to a cable in a sliding way; the front end of the nut sleeve is in threaded connection with the base, and the tail end of the nut sleeve props against on a boss at the outer edge of the shaft sleeve; corresponding to an inserting opening side, the base is provided with an annular elastic flap; an inner convex part is arranged on the inner ring surface of the annular elastic flap, and an outer convex part is arranged on the outer ring surface; a slope part with the shaft radium gradually reduced from the inserting opening side towards the inside is arranged on the inner edge surface of the shaft sleeve; the outer convex part props against on the slope part; an annular convex part is arranged on the outer edge surface of a socket joint body; and the annular convex part is clamped and connected with the inner convex part on the annular elastic flap. Due to the match between the nut sleeve and the slope part of the shaft sleeve, as well as the clamping connection between the annular elastic flap of the locking ring and the annular convex part, the threaded connection is combined with the pushing connection so as to realize the rapid and firm connection.

Description

technical field [0001] The invention relates to a connecting piece for communication equipment, in particular to a radio frequency coaxial connecting mechanism. Background technique [0002] In the field of communication technology, especially in the field of military and civilian microwave communication and precision testing, RF coaxial connectors are often used. In the field of radio frequency coaxial connectors, the connecting mechanism of the connector makes it possible for two connectors to be docked with each other, which depends on the required quality and impedance characteristics of the mating connection of the two interfaces, as well as the frequency of operation. The connection mechanism has a great influence on the performance of the connector. The following five common connection mechanisms are introduced in detail. [0003] Screwed Coupling Mechanism: This connection uses a coupling nut to connect. Pay attention to limit the maximum torque to prevent the nut ...
