Abstract
The invention discloses a precise-positioning welding jig for a microwave elastic transmission strip line. The precise-positioning welding jig comprises a base, a pressing plate, a positioning plate and a fixing plate. The base is integrally formed by a sunken step and a boss. The middle position of the upper surface of the boss is concave downwards to form a first semicircular groove, and the lower surface of the pressing plate is concave inwards to form a second semicircular groove matched with the first semicircular groove. The pressing plate is fixed to the boss, and the first semicircular groove and the second semicircular groove are combined in a covering mode to form a coaxial cable fixing groove. The thickness of the positioning plate is equal to the height of the boss, the positioning plate is mounted on the sunken step through pins and screws, the fixing plate is mounted on the positioning plate, and the elastic transmission strip line is additionally mounted between the positioning plate and the fixing plate. By means of the precise-positioning welding jig, precise-positioning welding of the elastic transmission strip line and a coaxial cable can be achieved, and it is guaranteed that the elastic transmission strip line can be welded to specific positions of inner and outer conductors on the tangent plane of the cable; meanwhile, the welding quality, the rate of finished products and the operation efficiency are greatly improved.
Description

Background technology
Microwave probe assembly, as the test accessories of microwave membrane circuit, is rely on welding elastic transport band line on coax and electrical contact and the impedance matching keeping certain realizes the transmission of test signal.
Elastic transport band line finally needs to be welded on the ad-hoc location of cable tangent plane internal and external conductor, but because elastic transport band line overall dimensions is small, and out-of-shape, width size is only 1.3mm, and coaxial cable diameter is only 1.2mm, the positioning welding operation easier meeting designing requirement therefore to be completed very large.
The welding manner of current employing is pure manual welding operation, first coaxial cable is fixed, then under the microscope elastic transport band line is positioned on the tangent plane of coaxial cable, by repeatedly adjusting the position of elastic transport line, finally estimate mutual alignment suitable after carry out welding operation again.
First the shortcoming of manual welding is accurately cannot be placed on the ad-hoc location of coaxial cable tangent plane by elastic transport line, and the mutual alignment relation of range estimation can not well meet design requirement; Next is in location adjustment repeatedly, easily causes the damage of elastic transport band line; Finally owing to being repeatedly adjust location under the condition of range estimation, therefore cause poor welding quality, welding efficiency is low and yield rate is low.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention proposes a kind of microwave elastic transport band line precision positioning weld jig being mainly used in elastic transport band line and welding with the precision positioning of coaxial cable.
The present invention adopts following technical scheme:
A kind of microwave elastic transport band line precision positioning weld jig, comprise pedestal, pressing plate, location-plate and fixed head, described pedestal by sunk type step and boss one-body molded, the recessed formation first in boss upper surface centre position semi-circular recesses, the lower surface indent of pressing plate forms the second semi-circular recesses with the first semi-circular recesses adaptation, pressing plate is fixed on boss, and the first semi-circular recesses and the second semi-circular recesses fasten and form coaxial cable holddown groove;
Location-plate thickness is equal with the height of boss, and location-plate is arranged on sunk type step by pin and screw, and fixed head is arranged on location-plate, adds elastic transport band line between location-plate and fixed head;
In use, first location-plate is installed on the sunk type step of pedestal with pin location, then pressing plate is installed on the boss of pedestal, and use screw prefastened; Subsequently coaxial cable is encased in the coaxial cable holddown groove between pedestal and pressing plate, when coaxial cable end face touches location-plate end face, pressing plate is completely fastening, now coaxial cable completely location and fastening; Then located with the pin on pedestal by elastic transport band line, install to location-plate upper surface, now elastic transport line and coaxial cable have completed accurate location; Finally fixed head is encased on location-plate with pin location, and uses screw completely fastening, can welding operation be carried out.
Further, described pedestal, pressing plate, location-plate and fixed head process by free machining precision metal.
Further, described pin is arranged on sunk type step, and sunk type step is also provided with screwed hole, and location-plate and fixed head are equipped with the pin hole corresponding with screwed hole position with pin on sunk type step and tapped through hole.
Further, described platen width is less than the boss width of pedestal, and pressing plate side is inclined-plane, and bevel angle is set to 45 °-65 °.
Further, the degree of depth of described first semi-circular recesses and the second semi-circular recesses is the radius size of coaxial cable, coaxial cable holddown groove and coaxial cable adaptation.
The Advantageous Effects adopting as above technical scheme to obtain is:
Utilize precision positioning weld jig, elastic transport band line can be realized weld with the precision positioning of coaxial cable, ensure that elastic transport band line can be welded on the ad-hoc location of cable tangent plane internal and external conductor, greatly improve welding quality, yield rate and operating efficiency simultaneously.
