Inner wire welding groove 10 and outer conductor welding groove 12 are respectively used to weld the inner wire and outer conductor of coaxial cable, and the insulation is situated between
Matter groove 11 is used for the dielectric for filling coaxial cable.
In the scheme of the short-circuiting terminal 100 and the coaxial cable short at one end, described coaxial cable one end houses
The inner wire welding groove is placed in the inner wire in the cell body 1 of the short-circuiting terminal 100, being embodied as the coaxial cable
In 10, the dielectric of the coaxial cable is placed in the dielectric groove 11, and the outer conductor of the coaxial cable is placed in institute
State in outer conductor welding groove 12.Then, it is then sharp toward the inner wire welding groove 10 with adding tin in the outer conductor welding groove 12
Manually the mode of welding or induction welding completes the welding of two positions of inner conductors and outer conductor, finally realizes coaxial cable
Short at one end.
The induction welding process of the short-circuiting terminal of the present invention and coaxial cable composition short-circuit structure is as follows：
First, short-circuiting terminal 100 is put into the special frock of induction welding so that it is fixed.Hereafter, will shear
Coaxial cable is positioned in the short-circuiting terminal, makes its inner wire and inner wire welding groove 10, dielectric and dielectric groove
11st, the position of outer conductor and outer conductor welding groove 12 corresponds, and uses frock by coaxial cable and the short-circuiting terminal 100
It is fixed.Then quantitative tin cream is expressed into the inner wire welding groove 10 of short-circuiting terminal 100 by numerical control device and outer conductor welds
The top of access slot 12.After the step of completing to add tin, then the welding corresponding to by ready coaxial cable and the short-circuiting terminal 100
Component is placed on induction welding stove porch, enables its flow into induction welding stove and then completes welding, at induction welding outlet of still
Take out coaxial cable and short-circuiting terminal 100 that welding is completed.
The short-circuiting terminal 100 can be completed to the outer conductor on coaxial cable in the case where keeping the same state of coaxial cable
With the welding of the position of inner wire, so as to realize the short circuit of coaxial cable one end so that operation is more convenient, is advantageous to improve life
Produce efficiency.In addition, the short-circuiting terminal 100 can be used for induction welding, reduce manual operation and further improve production efficiency.
Meanwhile the presence of the dielectric groove 11 is separated by inner wire welding groove 10 and outer conductor welding groove 12,
And then the inner wire of coaxial cable and outer conductor effectively can be subjected to subregion welding so that inner wire welding groove 10 with leading outside
Tin stream inside body welding groove 12 will not contact with each other.Therefore, the inner wire welding groove 10 and the outer conductor welding groove 12
The two pads it is separate, ensure that and do not have because failure welding caused by the mutual crossfire of scolding tin, so as to will not
Influence third order intermodulation index and influence the electricity function index of coaxial cable.
Fig. 2 is continued referring to, in a kind of embodiment of the short-circuiting terminal of the present invention, the cell body 1 welds in inner wire
Bottom land height at 12 3 groove 10, dielectric groove 11 and outer conductor welding groove groove positions is successively decreased successively.Due to the coaxial electrical
The diameter of the inner wire of cable, dielectric and outer conductor is incremented by successively, when inner wire welding groove 10, dielectric groove
11 and 12 3 groove positions of outer conductor welding groove bottom land height successively decrease successively, contribute to coaxial cable and the short-circuiting terminal 100
Matching connection, be more beneficial for the inner wire to coaxial cable and the welding of outer conductor position.More specifically, in this situation
In, inner wire welding groove 10 forms stop surface 2 with the intersection of dielectric groove 11.The dielectric is placed in the dielectric
During groove 11, its end face is closely attached on the stop surface 2, is advantageous to the space that the inner wire welding groove 10 forms a closing, energy
Sufficient tin liquor is enough stored, and prevents tin liquor from flowing to outer conductor welding groove 12.

The presence of confined planes 3, further prevent the tin stream crossfire of inner wire pad and outer conductor pad.
In another specific embodiment of the present invention, the cell body 1 is in inner wire welding groove 10, the and of dielectric groove 11
In the bottom land height of 12 3 groove positions of outer conductor welding groove, the bottom land of the inner wire welding groove 10 and outer conductor welding groove 12 is high
Degree is consistent and is less than the bottom land of the dielectric groove 11 height.
It is understood that during welding, the tin material made an addition in cell body 1 can become tin stream, in order to ensure
The inner wire of coaxial cable and the tin stream of outer conductor will not crossfire, the bottom land height of the dielectric groove 11 can not be less than simultaneously
The inner wire welding groove 10 and the outer conductor welding groove 12.
Specifically, at least one steam vent 4 is offered on the outer conductor welding groove 12.The presence of the steam vent 4 makes
Obtain during welding, gas can be discharged in time, tin stream is filled accumulation from bottom to top, avoid welding uneven cause
Third order intermodulation index deteriorates.
Certainly, the quantity of the steam vent 4, size, shape, position are adjusted according to the actual needs, are not exposed to
Limitation.In an embodiment of the present invention, the steam vent 4 is on the bottom land of the outer conductor welding groove 12 or side wall.This
Outside, the steam vent 4 can be provided with two.The increase of the quantity of the steam vent 4, be advantageous to increase capacity, accelerate gas
Discharge in time.
Specifically, two side of the cell body 1 at the outer conductor welding groove 12 extends to be formed a pair along short transverse
Rib pads 5.The presence of the rib pads 5 causes the pad of the outer conductor to accommodate more scolding tin, ensures the welding of outer conductor
It is more reliable, it is more secure.Similarly, the two side at the inner wire welding groove 10 also can extend to form a pair of shields along short transverse
Rib.
Specifically, the inner wire welding groove 10 and outer conductor welding groove 12 are set to arc-shaped, and the corresponding summary of its internal diameter
More than inner wire and the diameter of outer conductor, to be formed in welding between corresponding welding groove and conductor between the radial direction of accommodating solder
Gap so that when inner wire and outer conductor weld with cell body 1, periphery and the cell body inwall of conductor are all connected with so that welding is more firm
It is Gu reliable.
To sum up, the short-circuiting terminal can realize coaxial cable simultaneously when keeping same state with the coaxial cable
The welding of two inner wire, outer conductor pads, and the welding independence for causing two inner wire, outer conductor pads,
Production efficiency is effectively improved, and ensure that the position of two pads is not interfere with each other, it is therefore prevented that the weldering of two welding positions
Failure welding caused by tin crossfire, and then the third order intermodulation index of coaxial cable short-circuit structure is not interfered with, it ensure that coaxial electrical
The electricity function index of the stabilization of the short-circuit scheme of cable.
Fig. 5 is see also, meanwhile, present invention also offers a kind of feeding network component 200.The feeding network component 200
Including the short-circuiting terminal 100 described in above-mentioned any one.
Specifically, the feeding network component 200 includes coaxial cable 6 and inner wire 60 and outer conductor with coaxial cable
