Description

A kind of connector with quick locking structure

Technical field

The present invention relates to electric components and patch technical field, especially a kind of connector with quick locking structure.

Background technology

At present, the communications industry is used the radio frequency (RF) coaxial connector of relatively high power in a large number, and owing to requiring, voltage standing wave ratio is low, passive intermodulation index is low for the radio frequency (RF) coaxial connector of relatively high power, generally all adopts the connected mode with screw-threaded coupling.Although screw-threaded coupling connects reliable, exist following not enough: can not realize fast insert-pull, efficiency of assembling is lower, and must leave certain installing space between connector and connector, so that the use of handling nut tool is difficult to realize high-density installation.

According to the problem to the requirement of Fast Installation coaxial connector and the existence of above-mentioned technology, now also develop some and there is the radio frequency (RF) coaxial connector of quick locking structure, as application number is: 03103882.4 Chinese patent discloses a kind of electrical plug-in connector, it connects two linkage units by an annular coupling unit, this coupling unit has a lock ring, during locking, this lock ring fastenes the groove of first linkage unit automatically, and is locked on another linkage unit; Axially promote this lock ring, make it outside the groove in first linkage unit, make two linkage unit separation.Two linkage unit parts form electrical contact by an elastic contact element, and this contact element is annular disk, is arranged on the outside of insulator.

Although above-mentioned public technology has been realized fast lock between two linkage units with separated, voltage standing wave ratio and passive intermodulation are higher, cannot further reduce, and can only the less signal of through-put power, the scope of application is very restricted.

Summary of the invention

The object of the invention is a kind of connector with quick locking structure designing for the deficiencies in the prior art, employing is provided with the swivel nut of quick locking structure, promote swivel nut and can easily plug be become to good docking and the self-locking of butt end with socket-shaped, pull swivel nut to facilitate butt end separated by quick release, thereby improve the fast lock of connector and passive inter-modulation performance, reduce voltage standing wave ratio, simple in structure, connect reliably, easy for installation, be especially applicable to powerful signal transmission.

The object of the present invention is achieved like this: a kind of connector with quick locking structure, comprise plug and socket, plug is formed by swivel nut, binding ring, spring cover, pin insulator, plug inner conductor and plug outer conductor suit, socket is formed by socket inner wire, socket insulator and socket outer conductor suit, is characterized in that described plug outer conductor is provided with prelocalization groove and rear location notch; Described swivel nut one end is provided with and compresses and steel ball, and swivel nut is sleeved on plug outer conductor as being in axial sliding connection, and steel ball is elastic compression joint by hold-down ring and plug outer conductor; Described spring cover one end is the elasticity bulge that is provided with axial profile groove; Described binding ring one end is to be provided with axially grooved elastic card claw, and binding ring is arranged on spring and puts as being press-fitted connection; The butt end of described socket outer conductor is provided with groove, plug and socket are pegged graft, location notch after its swivel nut makes steel ball be slided into by the prelocalization groove of plug outer conductor under axial thrust, the elastic card claw of swivel nut compressing binding ring clamps in the groove of socket outer conductor, realize the fast self-locking that plug docks with socket, when swivel nut under axial tension, make steel ball by after location notch slide into prelocalization groove, the elastic card claw of binding ring flicks disengaging in the groove of socket outer conductor, realizes the plug quick release separated with socket.

Described steel ball is four and uniform being symmetrical arranged.

The present invention compared with prior art has simple in structure, connects reliably, improves the fast lock of connector and passive inter-modulation performance, greatly reduces voltage standing wave ratio, easy for installation, is especially applicable to powerful signal and transmits.

Embodiment

Consult accompanying drawing 1, the present invention is comprised of plug 1 and socket 2, plug 1 is formed by swivel nut 3, binding ring 4, spring cover 5, pin insulator 6, plug inner conductor 7, hold-down ring 8, steel ball 9 and plug outer conductor 10 suits, and socket 2 is formed by socket inner wire 21, socket insulator 22 and socket outer conductor 23 suits; Described plug outer conductor 10 is provided with prelocalization groove 11 and rear location notch 12; Described swivel nut 3 one end are provided with hold-down ring 8 and four uniform symmetrically arranged steel balls 9, and swivel nut 3 is sleeved on plug outer conductor 10 as being in axial sliding connection, and steel ball 9 is elastic compression joint by hold-down ring 8 with plug outer conductor 10; It is the elasticity bulge 51 that is provided with axial profile groove 52 that described spring overlaps 5 one end; Described binding ring 4 one end are to be provided with axially grooved 42 elastic card claw 41, and binding ring 4 is arranged on spring cover 5 as being press-fitted connection; The butt end of described socket outer conductor 23 is provided with groove 24.

Consult accompanying drawing 2, described plug 1 is formed by swivel nut 3, binding ring 4, spring cover 5, pin insulator 6, plug inner conductor 7, hold-down ring 8, steel ball 9 and plug outer conductor 10 suits, described pin insulator 6 and spring cover 5 and plug inner conductor 7 be concentric circles setting and with spring cover 5 and plug inner conductor 7 be interference fit; Described plug outer conductor 10 and binding ring 4 are sleeved on spring cover 5, and spring cover 5 is connected for being press-fitted with binding ring 4, and spring cover 5 is interference fit with plug outer conductor 10; Described swivel nut 3 is sleeved on plug outer conductor 10 and with plug outer conductor 10 as being in axial sliding connection.

Consult accompanying drawing 3, described binding ring 4 one end are to be provided with axially grooved 42 elastic card claw 41.

Consult accompanying drawing 4, it is the elasticity bulge 51 that is provided with axial profile groove 52 that described spring overlaps 5 one end.
