Technical field
The utility model belongs to TNC type radio frequency (RF) coaxial connector technical fields, and in particular to a kind of TNC with self-locking structure
Type radio frequency (RF) coaxial connector.
Background technology
TNC types radio frequency (RF) coaxial connector uses screw connection structure, has connection is reliable, and anti-vibration, impact resistance are strong etc.
Advantage.But as use environment becomes increasingly complex, using airborne, the complete machine device in the carrier-borne equipment such as vehicle-mounted is to connector
Connection reliability proposes higher requirement.Loosened to prevent from being threadedly coupled caused by the reasons such as jerk, so that whole
Machine breaks down, and some producers provide a kind of method of the installation insurance silk in bindiny mechanism, to increase the reliability of connection；
But found during specific use, the structure is comparatively laborious using process, is unfavorable for the installation of product repeated removal.
Utility model content
The purpose of this utility model is to provide a kind of TNC type radio frequency (RF) coaxial connectors with self-locking structure, with solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of TNC type radio frequencies with self-locking structure are same
Mandrel connector, including, swivel nut, contact pin, sealing ring, insulator, snap ring, shell, spring spool, spring, wire clamp, the swivel nut
Inner concentric sets shell one end, and rectangle annular groove is formed at the swivel nut and cage connection, snap ring is set in the rectangle annular groove,
The outside of the shell is arranged sealing ring, and sealing ring is arranged on the inside of swivel nut, the other end outside sheathed spring of the shell
Sleeve, the spring are arranged on the outside of shell and in the inside of spring spool, and the inside of the shell sets insulator, described
The inside of insulator sets contact pin, and one end of the shell is arranged wire clamp.
Preferably, one end of the swivel nut and spring spool is respectively provided with 45 ° of sawtooth.
Preferably, the swivel nut, spring spool, shell, insulator and contact pin are to be arranged concentrically.
Preferably, the exterior insulator is provided with cylinder clothes-hook, and the cylinder clothes-hook is 2 and is symmetrical arranged, described
The hanging groove coordinated with cylinder clothes-hook is offered on spring spool.
Technique effect of the present utility model and advantage：After plug and socket is to being inserted into position, the 45 ° of sawtooth and spiral shell of spring housing
Set 45 ° of complete teeth of sawtooth and, spring housing is because the stop of clothes-hook on plug body can not rotate, thus swivel nut will not yet
Backwards rotation can be produced and loosened, improve the reliability of connection, avoided because of the swivel nut pine caused by environmental factor such as vibration, impact
It is dynamic, reach connection reliably, the effect of anti-rotation.The utility model has the characteristics of convenient and practical.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-8, a kind of technical scheme provided by the utility model：A kind of TNC type radio frequencies with self-locking structure are same
Mandrel connector, including, swivel nut 1, contact pin 2, sealing ring 3, insulator 4, snap ring 5, shell 6, spring spool 7, spring 8, wire clamp 9,
The inner concentric of the swivel nut 1 sets the one end of shell 6, and swivel nut 1 and shell 6 junction forms rectangle annular groove, the rectangle
Snap ring 5 is set in annular groove, and the outside of the shell 6 is arranged sealing ring 3, and sealing ring 3 is arranged on the inside of swivel nut 1, the shell 6
The other end outside be arranged spring spool 7, the spring 8 is arranged on the outside of shell 6 and in the inside of spring spool 7, described
The inside of shell 6 sets insulator 4, and the inside of the insulator 4 sets contact pin 2, and one end of the shell 6 is arranged wire clamp 9.Institute
The one end for stating swivel nut 1 and spring spool 7 is respectively provided with 45 ° of sawtooth.The swivel nut 1, spring spool 7, shell 6, insulator 4 and contact pin
2 be to be arranged concentrically.Cylinder clothes-hook 10 is provided with outside the insulator 4, the cylinder clothes-hook 10 is 2 and is symmetrical arranged,
The hanging groove 11 coordinated with cylinder clothes-hook 10 is offered on the spring spool 7.
Embodiment：Socket is fixed by screws in installation panel, when starting to inserting, 45 ° of sawtooth and spring housing on swivel nut 1
45 ° of separated states of sawtooth on cylinder 7, are equipped with spring 8, the cylinder clothes-hook of the outer surface of shell 6 between spring spool 7 and shell 6
