Description
Technical field
The present invention relates to a kind of assembly tool, especially a kind of radio frequency (RF) coaxial connector assembly tool with torque.
Background technique
Common radio frequency coaxial connector assembly tool is made of clamp and handle.There are mainly two types of structure types at present: one
Kind is band moment function, and clamp part is similar with common wrench head, is inserted in use, blocking radio frequency (RF) coaxial connector with clamp
The outer-hexagonal part of head, tightens radio frequency (RF) coaxial connector plug by torque, though this assembly tool with moment function, by
The axis of entire radio frequency (RF) coaxial connector assembly tool is vertical with the rotation axis of radio frequency (RF) coaxial connector plug when tightening, because
This, clamp part will occupy certain space in rundown process.Another kind is the axis of assembly tool in entire assembling process
The line rotation axis coincident with radio frequency (RF) coaxial connector plug always, though it does not need to occupy too many during tightening plug
Space, still, this assembly tool will cause too loose or too tight when plug is screwed with socket without torque function, and Guo Songyi is led
Cause connection unreliable, tension easily leads to device failure.
With miniaturization, the fast development of high integration electronic product, there is an urgent need to one kind to be both not take up more operation sky
Between, and the Novel radio frequency coaxial connector assembly tool with moment function.
Summary of the invention
It is an object of that present invention to provide a kind of the radio frequency (RF) coaxial connector assembly tool with torque, solution prior art occupancy
Space is big, screws the problem of connecting device unreliable and easy to damage.
A kind of radio frequency (RF) coaxial connector assembly tool with torque, comprising: clamp, handle, bearing, spring, steel ball, retaining ring
And sunk screw.
The clamp is formed by a cylindrical steel rods overall processing, and clamp middle section has semicircular cavities, with semicircle
There are four checkpost slots, the size of card slot determines that clamp is another according to the size of plug to be assembled on one end inner wall that cavity is connected
One end have three-level concentric circular grooves structure, the diameter of three circular grooves be sequentially reduced from outside to inside and the depth of groove by
It is cumulative big, there is cylindrical boss, the cylinder boss and third level recess sidewall on the bottom center position of third level groove
Between there is gap, cylinder boss penetrates through and is divided into two parts by linear spring groove, wherein the both ends of spring groove and the third level
Groove cavities connection, spring groove are identical as the depth of third level groove.
The bearing is located in first order groove and is interference fitted with first order groove inner wall, and the spring is located at spring groove
Interior, both ends of the spring respectively has a steel ball, and the diameter of steel ball and the outer diameter of spring are respectively less than the height of cylinder boss.
The handle is formed by a cylindrical steel rods overall processing, and one end of handle and bearing bore diameter are interference fitted and hold
There are two cylindrical projections for portion surface tool, and two cylindrical projection opposite handle ends center of circle is symmetrical, and two cylindrical projections protrude into
In the gap of third level groove and with third level groove inner wall clearance fit, the center of two cylindrical projections is located at two steel balls
The outside of the heart, i.e., the center of two cylindrical projections are less than in the steel ball centre of sphere and third level groove at a distance from third level groove inner wall
The distance of wall；Handle inner is hollow structure, and outer wall surface has annular knurl, and retaining ring is to consist of two parts, and a part is socketed in
The end of clamp, another part are socketed on handle, are fastened after clamp assembles in place with handle by retaining ring and sunk screw.
Assembly tool in use, four checkpost slots of clamp block the outer-hexagonal part of plug, cable entrained by plug into
Enter in the semicircular cavities inside clamp, the annular knurl position held on handle is rotated, and can be generated when plug is screwed with socket
Torque, due to handle end two cylindrical projections center at the outside of the steel ball centre of sphere, rotatable handle, cylindrical projection generate
Steel ball is pressed into the component in spring groove, plug and the torque that socket screws generation early period are smaller, and two cylinders on handle are convex
It rises and is not enough to a steel ball and pushes back in spring groove completely, therefore, handle drives clamp to be rotated, to realize plug and socket
It constantly screws, when plug screws to a certain extent with socket, required torque is bigger, at this point, two on handle circle
Column protrusion pushes back steel ball in spring groove completely, and handle and clamp have skidded, and plug and socket reach pre-set torque
The size of point, required torque is adjusted by length.
The axis of the assembly tool rotation axis coincident with radio frequency (RF) coaxial connector plug always, assembly tool in this technology
It occupies little space, be easy to implement, is low in cost, screwing that connection is reliable, is hardly damaged device.
