Abstract
The utility model relates to a snap ring free radio frequency coaxial connector, comprising a nut (1) and a shell (5); the utility model is characterized in that: a convex body (3) of the shell (5) is embedded into a tool recess (7) of the nut (2); the outerwall of the convex body (3) and the innerwall of the nut (1) are all provided with screw threads; the screw threads of the convex body (3) of the shell (5) are matched with the screw threads of the nut (1). The shell is screwed in the nut through the screw threads and the convex body is completely inserted into the toll recess of the nut, then a sealing ring is arranged on a ring shaped platform of the convex body from the head of the nut, the shell is clamped in the nut, and the installation of the connector is finished. The structure does not use the special snap ring, and needs no special assembly frocks when assembled; assembly workers need no special training and can install the connector quickly, thereby being time-saving and labor-saving and reducing installation cost of products.
Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector, particularly a kind of no snap ring radio frequency (RF) coaxial connector.
Background technology
SMA-J type radio frequency (RF) coaxial connector is connected nut with snap ring with shell traditionally, snap ring is a kind of " C " type ring, outside inner at nut and shell has ring shaped slot respectively, snap ring is enclosed within the ring shaped slot of shell, compress snap ring with special tooling then and pack in the nut, nut and shell are interconnected by the elasticity of snap ring.This structure the time needs special tooling in assembling, the assembler is needed special training, and will process specially snap ring, both waste material, increase cost, again can not Fast Installation, time-consuming, operating efficiency is lower.In application in the past, also have elastic problem to cause nut to come off, thereby cause the connector failure phenomenon because of snap ring.
Summary of the invention
The technical problems to be solved in the utility model is for overcoming deficiency of the prior art, and a kind of simple in structure, cost is lower, installation is rapid, functional reliability is high no snap ring radio frequency (RF) coaxial connector is provided.
The technical solution that realizes above-mentioned purpose is:
This no snap ring radio frequency (RF) coaxial connector comprises nut and shell, and it mainly is that the outer wall of outer convex body and the inwall of nut are equipped with screw thread in the escape of outer convex body inserted num of shell.
Its further technical solution is:
The screw thread on the outer convex body of shell and the threaded engagement of nut.
The technique effect that the utility model produced is:
In this structure, do not use special snap ring, in the assembly tooling specially of when assembling, to the assembler also without special training, but Fast Installation, time and labour saving, reduction product installation cost;
Snap ring is general to be adopted with beryllium-bronze processing, then through working procedure processing moulding such as heat treatment are qualitative.This structure is lacked " C " type snap ring with structure in the past when designing, thereby can reduce the material cost of product.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, this connector has a nut 1 and shell 5, the insulator 6 that the centre is provided with contact pin 4 directly and shell 5 closely cooperate.On the outer wall of shell 5, be provided with convex body 3 outside the circle, have screw thread on the outer convex body 3.On the inner headed face of nut 1, also be provided with screw thread, and between the termination of this screw thread and nut 1, be provided with escape 7.The annular table place of outer convex body 3 is equipped with a sealing ring 2.
During installation with shell 5 by in the screw thread precession nut 1, make outer convex body 3 fall into the escape 7 of nut 1 fully, the annular table of convex body 3 outside the head of nut 1 is loaded to sealing ring 2 snaps in shell 5 in the nut 1 again, promptly finishes the installation of this connector.
In this structure, nut 1 with used the escape 7 in the nut being connected of shell 5 cleverly, in nut 1 design one have externally threaded outside convex body 3, shell 5 is screwed in the nut 1, threaded portion in the shell 5 is fallen in the escape 7 of nut 1 fully, matching with outer convex body 3 in the nut 1 snaps in shell 5 in the nut 1, thereby realizes being connected of nut 1 and shell 5.
Claims (2)
1, a kind of no snap ring radio frequency (RF) coaxial connector comprises nut (1) and shell (5), it is characterized in that the inwall of the outer wall of outer convex body (3) and nut (1) is equipped with screw thread in the escape (7) of outer convex body (3) inserted num (2) of shell (5).
2, no snap ring radio frequency (RF) coaxial connector as claimed in claim 1 is characterized in that the screw thread on the outer convex body of shell (5) (3) and the threaded engagement of nut (1).
