Technical field
The utility model relates to a kind of weld fixtures, are specifically related to a kind of SMP radio-frequency joint welding fixture, belong to
Art communication systems field.
Background technique
With the development of communication and radar, more stringent requirements are proposed to communication system by people, it is desirable that and device volume is smaller,
It is used for above various communication devices so this Miniature RF connector of SMP is more and more extensive, and SMP radio-frequency joint can be burnt
Knot, air-tightness is good, and military aspect is even more widely used.
The used SMP radio-frequency joint welding fixture of our companies uses front snap ring mounting means, snap ring and pedestal at present
It is gap-matched mode, this mode will control between -0.01 to+0.02 requirement on machining accuracy height, build-up tolerance band.
Assembly is complicated, and skilled craftsman is needed to assemble by the way of pressing the fourth of the twelve Earthly Branches, and later maintenance maintenance is also inconvenient, is substantially broken and just reports
It is useless, so that entire production cost is higher, it is not easy to the further genralrlization of product.Therefore, a kind of new scheme solution of urgent need
The certainly technical problem.
Utility model content
To solve the above problems, the utility model discloses a kind of SMP radio-frequency joint welding fixture, the technical solution structure
Simply, it is easily assembled, maintenance convenient for safeguarding, repeated disassembled and assembled does not influence fixture performance, and interchangeablity is strong, and any component interchanging is non-
It is often convenient.
In order to reach the goals above, the utility model provides the following technical solutions: a kind of SMP radio-frequency joint welding fixture,
It is characterized in that, the SMP RF welding fixture includes pedestal, thimble, spring and screw capping, the thimble is put into pedestal,
Thimble front end is stretched out from pedestal front end aperture, and the spring is placed on behind thimble, the screw capping by being threaded on pedestal,
Thimble and spring in pedestal, pressing spring makes spring withstand thimble, completes assembly.
As a kind of improvement of the utility model, the SMP- of the pedestal ring flange size and the docking of SMP radio-frequency joint
KFB2 cable connector flange size is the same, and installation pore size is the same.It can use docking SMP- ready-made on device box body in this way
KFB2 cable connector mounting hole, assembly and disassembly welding fixture do not affect device box body character itself and subsequent operation.Pedestal mounting hole
Two cylinder small boss of lower convexity, make pedestal flange and device keep certain height, and heat is seldom from weld clip when freezing in this way
Tool sheds, and solder will not be because of spilling on ring flange on a small quantity.
As a kind of improvement of the utility model, the thimble uses stainless steel material, when freezing not only high temperature resistant but also
Discord solder reacts.The thimble is step-like using two sections, and SMP is pushed down by base aperture in top under the pressure of the spring
Radio-frequency joint, makes connector be close to aperture cavity, and rearward diameter is greater than top card and play the guiding role in pedestal.At the top of the thimble
Diameter of phi 2.7mm is simultaneously provided with the hole that a diameter is greater than SMP radio-frequency joint contact pin, with keeping clear of joints contact pin.
As a kind of improvement of the utility model, the screw capping screw thread is connected with pedestal, and pressing spring is allowed to elastic top
Firmly thimble.After having assembled, thimble is made to stretch out pedestal ring flange not less than 3mm distance.The spring has certain length, guarantees screw capping
There is certain pressure when pushing down.
Compared with the existing technology, advantages of the present invention is as follows: 1) the utility model assembly precision requires to reduce, so that processing
Simply, accurate to dimension, which meets the requirement of GB/T1804-m general precision, (to reduce 1-2 number than original machining accuracy
Magnitude), 2) snap ring is eliminated, it is easily assembled.3) maintenance convenient for safeguarding, repeated disassembled and assembled do not influence fixture performance, and 4) component interchanging
Property it is strong, any component interchanging is very convenient, better than the domestic prior art.And this fixture is by changing pedestal ring flange size not
Changing other part sizes can extend to most of need in the structure of sintered joint.
Detailed description of the invention:
Fig. 1 is the utility model overall structure assembling schematic diagram；
Fig. 2 is the utility model SMP radio-frequency joint welding fixture clamping SMP radio-frequency joint schematic diagram；
In figure: 1, pedestal, 2, thimble, 3, spring, 4, screw capping, 5, pedestal ring flange, 6, device shell, 7, mounting screw,

Specific embodiment
In order to deepen the understanding and understanding to the utility model, with reference to the accompanying drawing with embodiment to the utility model into
One step explanation and introduction.
Embodiment 1: referring to Fig. 1, a kind of SMP radio-frequency joint welding fixture, the SMP RF welding fixture include pedestal 1,
Thimble 2, spring 3 and screw capping 4, the thimble 2 are put into pedestal 1, and thimble front end is stretched out from pedestal front end aperture, the bullet
Spring is placed on behind thimble, and the screw capping is by being threaded on pedestal, and thimble and spring in pedestal, pressing spring makes bullet
Spring withstands thimble, completes assembly, is provided with pedestal ring flange 5 below the pedestal, the pedestal ring flange 5 passes through mounting screw
7 are fixed on device shell 6.The SMP-KFB2 cable connector flange size of 5 size of pedestal ring flange and the docking of SMP radio-frequency joint
Equally, installation pore size is the same.It can use docking SMP-KFB2 cable connector mounting hole ready-made on device box body in this way, fill
Sealing-off welding fixture does not affect device box body character itself and subsequent operation.Two cylinder small boss of pedestal mounting hole lower convexity,
Pedestal flange and device is set to keep certain height, heat seldom sheds from welding fixture when freezing in this way, and solder will not be because of
