Abstract

The utility model relates to a fast-plugging self-locking radio frequency coaxial connector, which comprises a connector and is characterized in that an axially sliding block (10) is arranged between a shell (17) and a pressed sleeve (9); the two side of the sliding block are the bevels (18 and 18') and the two bevels respectively match the two vanes (23 and 23') at the foot of the spring plate (11). During plugging, the spring sheet is chucked in the groove (7) to realize the self-locking; and during unlocking, the pressed sleeve is pushed (9) to press the sliding block. Through the bevel, the spring sheets are force to open and then the connector is pulled out. The connector has a simple structure, strong shock-resisting performance, high reliability and excellent mechanical and electric performance, so the connector can be widely used to connect the radio frequency coaxial cable in the wireless electric equipment and instrument under the vibrating or harsh environment.

Description

Fast-insertion self-locking RF coaxial connector

Technical field

The utility model relates to a kind of radio frequency (RF) coaxial connector, particularly fast plugging and self-locking coaxial connector.

Background technology

N series of products in the radio frequency (RF) coaxial connector are middle high-power coaxial connectors of a kind of widely used screw connection structure, the relevant regulations that meets MIL-C39012, IEC169 and CECC22210, have that shock resistance is strong, reliability is high, characteristics such as mechanical performance and excellent electrical properties, be widely used in shaking with severe environmental conditions under wireless device and instrument in be connected radio frequency coaxial-cable.But because the interface of N series of products is screw connection structures, can not realize the fast insert-pull function, need to use specific purpose tool in the assembling process, both lose time, and the back product is installed be rotated arbitrarily.Though some company directly takes down interface thread and realizes fast insert-pull using when only limiting to experiment test, can not be used for real work in a large number temporarily.

Summary of the invention

The technical problems to be solved in the utility model is in order to overcome the deficiencies in the prior art, and provide that a kind of shock resistance is strong, reliability is high, machinery and excellent electrical properties, the fast-insertion self-locking RF coaxial connector that has the fast-insertion self-locking function again.

Technical solution of the present utility model is: be provided with a slide block that slides vertically between shell and gland, two sides of slide block are the inclined-plane, work in coordination with two fins at reed end pin place respectively in these two inclined-planes.

Further technical solution of the present utility model is: be provided with a projection in the middle of the arc of reed, said fin opens to both sides are oblique.

Inner bottom part at shell is equipped with a spring coil.

Be by the good effect that technical solution of the present utility model produced: this connector be on the basis of N series of products structure in addition improvement, kept that it is high-power, shock resistance good, reliability is high, the advantage of machinery and excellent electrical properties, can also realize fast insert-pull, self-locking excellent function, and in assembling process, can save time, reduce assembly space, reduce assembly cost, can be widely used in being connected of radio frequency coaxial-cable in wireless device and the instrument under vibrations and the adverse circumstances.

Embodiment

Shown in Fig. 1-8, the female connector in the utility model is made of shell 1, insulator 2 and jack 3, is provided with groove 7 and boss 6 (referring to Fig. 2) on shell 1.

And male connector is to constitute (referring to Fig. 3) by shell 17, pressure ring 8, gland 9, slide block 10, reed 11, sealing shroud 12, insulator 13, sealing ring 14, contact pin 15, spring coil 16.Wherein mainly be between the gland 9 of male connector and shell 17, be provided with one can be along shell 17 slide block 10 in axial sliding, this slide block 10 is an arc, and two sides are inclined-plane 18,18 ' (referring to Fig. 4).Be arranged with rectangle groove 19 (referring to Fig. 5) on the tubular housing 17, two sides 22,22 ' radially that are the reed 11 of U font are connected in these two grooves 19 (referring to Fig. 8), slide block 10 is constrained in by gland 9 on the outer wall of shell 17, two inclined-

planes

18,18 of slide block 10 ' with two

oblique fins

23,23 of reed 11 front ends ' contact.Reed 11 also is provided with a projection 21, in the time of can preventing that reed 11 is stressed from radially sliding ejection, to improve the combination degree with slide block 10.Also place the annular spring coil 16 of perforate in the middle of at the inner bottom part of shell, the centre of this spring coil 16 is provided with flanging, its radially section be a splayed (referring to Fig. 6,7).Female connector inserts its end face of back and directly compresses spring coil 16, so can guarantee the performance that is electrically connected of this connector.

As yin, yang connector when inserting (referring to Fig. 1) mutually, two

sides

22,22 of reed 11 ' be subjected to the extruding of female connector shell 1 convex platform 6 and radially opening to both sides.When continuing to insert, rely on the elastic reaction of reed 11, snap in the groove 7 and realize locking function.If when wanting release, only need to axially exerting oneself a little gland 9, gland 9 compressing slide blocks 10 and make two

fins

23,23 on the reed 11 of two inclined-planes 18,18 ' oppress ', make reed 11 open and break away from groove 7 on the female connector to both sides, thereby female connector can be extracted from male connector, realize unlocking function, plug very conveniently that and switching performance is very reliable.

Claims

1, a kind of fast-insertion self-locking RF coaxial connector, comprise the male connector part, it is characterized in that between shell (17) and gland (9), being provided with a slide block (10) that slides vertically, two sides of slide block (10) are inclined-plane (18,18 '), work in coordination with two fins (23,23 ') at reed (11) end pin place respectively in these two inclined-planes (18,18 ').

2, fast-insertion self-locking RF coaxial connector as claimed in claim 1 is characterized in that being provided with a projection (21) in the middle of the arc at reed (11), and said fin (23,23 ') opens to both sides are oblique.
