Abstract
A radio-frequency coaxial electric connector with an interface shifting and rotating prevention function comprises an inner conductor, an outer shell, and an insulated support pressed into the place between the inner conductor and the outer shell. The front end of an inner hole of the outer shell is provided with a stepped hole. An outer circular step with a shaped adapted to the shape of the stepped hole is arranged in the front end of the insulated support at the place corresponding to the stepped hole in the front end of the inner hole of the outer shell. The outer shell and the insulated support are positioned by the stepped hole and the outer circular step. Two key grooves are formed opposite to each other along the diameter direction in the stepped hole. The outer peripheral face of the outer circular step is provided with two keys matched with the two key grooves from the prospective of position and shape. According to the utility model, the shifting and rotating problems of the electric connector are solved; the insulated support disengagement generated when the electric connector is subject to heat and vibration is prevented; the problem of the insulated support rotation generated during the plugging and using process of the connector is solved; the reliability of the electric connector is improved; the interface size of the electric connector is ensured; and the consistency of electrical performance indexes, such as voltage standing-wave ratio, insertion loss, and phase, is guaranteed.

Background technology
Existing SMA type connector is owing to being subject to the restriction of usage space size, insulator and the shell body mode that is fixed with pressure that is mostly adopting, although it is simple, convenient and swift that this frame mode assembles, but be subject to the impact of insulating material, accurate to dimension larger, the impact that is in use subject to temperature shock may occur that insulator sizes variation causes insulator obscission, makes the application of product have significant limitation; Because product is to be threaded, product plugs together in process, in the time applying coupling torque, may cause the rotation of product simultaneously.
The structure of current existing anti-channeling anti-rotation has following several frequently seen form:
1) unthreaded hole press-fit structure, insulating supporting and shell body are directly press-fitted, simple in structure, but it is larger affected by temperature environment, easily occurs insulating supporting obscission, and application has great limitation;
2) epoxy sealing structure, this kind of structure can play the effect of anti-channeling to a certain extent, but anti-rotation torque is little, and product uses high temperature to reduce to 105 DEG C by 165 DEG C;
3) hangnail structure, this kind of structure can play certain anti-channeling function, but can not solve rotational problems;
4) some riveting knot structure, this kind of structure is the fixed form that the deflection by shell body being got ready to generation forms insulating supporting, and anti-channeling anti-rotation capacity reliability is poor, and present highly reliable connector is not generally taked this mode.
Summary of the invention
For solving above-mentioned problems of the prior art, the purpose of this utility model is to provide the radio frequency coaxial electric connector of a kind of interface anti-channeling anti-rotation, solve the problem that electric connector play rotates, the problem that makes product avoid insulating supporting to come off in the time standing temperature and vibration condition, solve the problem of connector to insulating supporting rotation in slotting and use procedure, improve the reliability of product, ensured the interface dimensions of connector, and the consistency of the electricity function index such as voltage standing wave ratio, insertion loss, phase place is guaranteed.
For achieving the above object, the technical scheme that the utility model adopts is:
The radio frequency coaxial electric connector of a kind of interface anti-channeling anti-rotation, comprise inner wire 1, shell body 3 and be pressed into inner wire 1 and shell body 3 between insulating supporting 2, the endoporus front end of described shell body 3 is provided with stepped hole 3-1, the corresponding position, stepped hole position of the front end of described insulating supporting 2 and shell body 3 endoporus front ends is provided with the cylindrical step 2-1 suitable with stepped hole 3-1 shape, and described shell body 3 and insulating supporting 2 position by stepped hole 3-1 and cylindrical step 2-1; In described stepped hole 3-1 along diametric(al) to having two keyway 3-2, on described cylindrical step 2-1 outer peripheral face, be provided with respectively two key 2-2 corresponding with two keyway 3-2 positions, shape adaptation.
Compared to the prior art, tool has the following advantages the utility model:
1, the utility model positions shell body 3 and insulating supporting 2 by the stepped hole 3-1 of shell body 3 endoporus front ends and the cylindrical step 2-1 of insulating supporting 2 front ends, ensure that product insulating supporting can not come off under temperature and vibration condition, also ensured the interface dimensions of product simultaneously, improve the environmental resistance of radio frequency coaxial electric connector, the consistency of the electricity function indexs such as voltage standing wave ratio, insertion loss, phase place is effectively improved.
2, the utility model is by shell body 3 and the keyway 3-2 of insulating supporting 2 and coordinating of key 2-2, avoided product plug and socket to plug together and use procedure in the rotational problems of insulating supporting.
