Description
Technical field
The present invention relates to a kind of quick locking radio frequency (RF) coaxial connector, belong to radio frequency (RF) coaxial connector technical field.
Background technology
Traditional military radio frequency (RF) coaxial connector, generally uses the swivel nut that connects of connector to beat the mode of wire hole, utilizes steel wire to bundle after mounting, and antivibration is anti-loosening；When safeguarding, need to adjust steel wire dismounting, then the connection swivel nut of connector of outwarding winding with spanner, such mode has problems and is a little: the installation and removal time is long, expends man-hour and it needs to specific purpose tool；Installing space is had restriction in the majority, is not suitable for the little space mounting of high density.
Summary of the invention
What the present invention proposed is a kind of quick locking radio frequency (RF) coaxial connector, its purpose is intended to the defect overcome existing for prior art, make connector not only have the function preventing thread looseness, but also there is energy Fast Installation maintenance, the function of the little space mounting of suitable high density.
The technical solution of the present invention: a kind of quick locking radio frequency (RF) coaxial connector, its structure includes shell 1, cylindrical set 2, spring 3, swivel nut 4, connects swivel nut 5, pin 6, draw-in groove 7, bayonet mechanism 8；Wherein connect swivel nut 5 and cylindrical set 2 is correspondingly arranged on the axial location of quick locking radio frequency (RF) coaxial connector；Spring 3 loads in the draw-in groove 7 of cylindrical set 2 and shell 1；With gear on swivel nut 4, connection swivel nut 5, swivel nut 4 overall generation displacement is made by bayonet mechanism 8, swivel nut 4 separating along connector shaft engaging when generation displacement, the gear on swivel nut 4 and the gear connected on swivel nut 5 produce locking with when dismantling forward or backward.
The invention have the advantages that
1) save security thread hole, reduce the problem that the perforation processing connecting swivel nut of connector is difficult, shorten the process-cycle；
2) use gear mechanism, eliminate perforation and the binding action of steel wire, easy to operate, quick, simple, there is more preferable vibration resistance so that connector has fabulous reliability and repeatability；
3) have employed spring mechanism so that carry cogged cylindrical set to move forward and backward, and in the case of connector locking, it is provided that certain forward thrust；
4) gear that connection swivel nut and cylindrical put is with certain oblique angle, clockwise direction and opposite direction is made to rotate the moment of torsion difference needed the biggest, making in the case of locking installed by connector, connecting swivel nut needs to overcome great moment of torsion could occur to loosen, and such design provides great vibration resistance；
5) have employed bayonet arrangement, during unblock, the bayonet socket of cylindrical set is by boss screens, cylindrical set can not be moved forward and backward, during locking, the bayonet socket of cylindrical set can only move axially by boss relatively, cylindrical set is difficult to rotate, and such design also greatly improves reliability of structure and the vibration resistance of connector itself；
6) swivel nut 4 uses and screws in press-fit, solves spring mechanism installation question very well；
7) cylindrical set 2 is positioned at socket end rather than plug end so that socket connector is relatively reliable with the locking of plug connector and stable.

In accompanying drawing 1 is shell 1, cylindrical set 2, spring 3, swivel nut 4, connects swivel nut 5, pin 6, draw-in groove 7, bayonet mechanism 8.
Detailed description of the invention
Comparison accompanying drawing, a kind of quick locking radio frequency (RF) coaxial connector, its structure includes shell 1, cylindrical set 2, spring 3, swivel nut 4, connects swivel nut 5, pin 6, draw-in groove 7, bayonet mechanism 8；Wherein connect swivel nut 5 and cylindrical set 2 is correspondingly arranged on the axial location of quick locking radio frequency (RF) coaxial connector；Spring 3 load cylindrical set 2 and shell 1 draw-in groove 7 in formed spring mechanism；With gear on swivel nut 4, connection swivel nut 5, swivel nut 4 overall generation displacement is made by bayonet mechanism 8, swivel nut 4 can separate with when dismantling forward, backward along connector shaft engaging when generation displacement, the gear on swivel nut 4 and the gear connected on swivel nut 5 produce locking.
Described cylindrical set 2 is provided with bayonet mechanism 8, and shell 1 sets pin 6, and when rotating and pull cylindrical to overlap 2, pin 6 moves in bayonet mechanism 8.
Described swivel nut 4 is with internal thread, with the external screw thread mated with swivel nut 4 on shell 1, load in shell 1 by rotating, by cylindrical set 2 by tool locating, swivel nut 4 is axially pressed for 2 times to cylindrical set, be press-fitted integral with cylindrical set 2, under the thrust of spring spring 3, cylindrical set 2 can move to the screw position of shell 1 end face, but can be blocked by the screw thread of shell 1 end face, and swivel nut 4 and cylindrical set 2 form draw-in groove 7 after completing to be press-fitted.
The stroke of described spring mechanism and thrust meet when cylindrical set is released can completely be connected swivel nut 5 and engage；Have employed bayonet mechanism 8, pin 6 screens can be passed through when retracting cylindrical and overlapping 2.
Described swivel nut 4, connecting and successively decrease to the center of circle with gear, the width of gear on swivel nut 5, the height of gear is constant, and gear height is less than 0.3mm, and gear is with two oblique angles, and wherein an angle is 90 °, and another angle is acute angle；When gear engages, when quick locking radio frequency (RF) coaxial connector is vibrated cause connecting swivel nut 5 will produce reversion time, due to the effect of gear, cylindrical set 2 will hinder the rotation connecting swivel nut 5, thus it is locking to realize antivibration.
Described spring 3 is compression spring, and two ends also tightly polish.
Spring 3, with draw-in groove 7 structure, can be loaded in this draw-in groove, and spring can compression smoothly by described cylindrical set 2 and shell 1.
Pin 6 it is machined with on shell 1.
During specific works, the gear connecting swivel nut 5 and cylindrical set 2 can complete well to engage and separate.
Comparison accompanying drawing 2, under connector locking state, if needing to unlock, it is only necessary to by swivel nut 4 along connector shaft to pulling back, the gear of swivel nut 4 and the gear of connection swivel nut 5 is allowed to separate, rotate cylindrical set 2 simultaneously, the bayonet socket allowing cylindrical set 2 is blocked by pin 6 so that cylindrical set 2 cannot be carried out moving axially, and can only be rotated, now swivel nut 4 cannot stop and connect loosening of swivel nut 5, thus reaches the purpose unlocked.
Comparison accompanying drawing 3, it is in tightening state connecting the swivel nut 5 swivel nut 4 with butt end, when needs are locked, rotate swivel nut 4, pin 6 is allowed to be at bayonet socket axially open, at this moment swivel nut 4 can freely be pushed ahead, the gear of swivel nut 4 just can be engaged with the gear being connected swivel nut 5, if connecting swivel nut 5 effect vibrated or other external force to start to loosen, so connect swivel nut 5 necessarily to start to rotate and due to the reason of gear engagement, band movable snail sleeve 4 starts to rotate simultaneously, but now pin 6 is at bayonet socket axially open, pin 6 prevents the rotation of swivel nut 4, even if so that connection swivel nut 5 is vibrated or the effect of other external force, also it is difficult to loosen, thus arrive the purpose of locking.
The connection swivel nut 5 of connector itself is small-sized, and the position adding work gear is the most limited, and the especially number of teeth of gear is more, and tooth depth only has about 0.3.
Cylindrical set must is fulfilled for the range demands of cylindrical set with the bayonet socket size of boss and can position when cylindrical set is return and not get loose in the case of not rotating cylindrical set；Boss can overlap to foreign round and carry out screens, and opening size postpones, before meeting cylindrical set, the status requirement retracted.
