Utility model content
The purpose of this utility model is: provide a kind of many sizes direct insertion filters to test seat, during to solve direct insertion filters to test, the mode of conventional clamping or individual size test bench is adopted to carry out testing brought mechanical damage, loose contact, easily short circuit, easily maloperation, easily cause larger test data error and the problem such as testing efficiency is low.
Scheme of the present utility model is as follows: the direct insertion filters to test seat of a kind of many sizes, comprise framework, draw runner, slide block, test needle stand and p-wire, described draw runner is transversely arranged, draw runner is slidably arranged on the end face of framework one end, and draw runner longitudinally slides, described slide block is slidably arranged on draw runner along the length direction of draw runner, slide block is provided with the second through hole, test needle stand is arranged in the second through hole, and one end of p-wire is fixed on test needle stand.
Described framework is square framework, and framework inside is square hollow-core construction.
The two side of described framework one end offers respectively first chute, two the first chutes are arranged along the length direction of two side on framework end face respectively, and the two ends of described draw runner are slidably arranged in two the first chutes respectively.
Described first chute is provided with the first limited screw.
The sidewall of described framework offers the first through hole of through frame side wall, described draw runner offers the second chute along its length, the bottom of the second chute offers the third through-hole of through draw runner along the length direction of draw runner, described skid is arranged in the second chute, described second through hole is connected with third through-hole, and described p-wire is through in third through-hole and the first through hole successively.
Described second chute is provided with the second limited screw.
The aluminum alloy material that described framework is structure as a whole, draw runner is metal material, and the material of slide block is teflon.
Described test needle stand is bonded in the second through hole, and p-wire is welded on test needle stand.
Compared with prior art, major advantage is as follows for the utility model:
Compared with the mode clamped with routine, described test bench is without the need to using metal holder, thus avoid weldability device pin coating being caused to damage influence device, avoid because metal holder causes short circuit and burn device, and checking metal holder whether short circuit and affect the problem of testing efficiency;
Compared with existing individual size test bench, test bench described in the utility model can adjust draw runner on test bench and slide position according to the difference of institute's test filter size and pin positions, thus the second through hole on test bench and wave filter pin positions are matched, make described test bench versatility high, the wave filter of different size can be adapted to and it is tested, eliminate often kind of size filter all to need to make the time spent by corresponding test bench simultaneously, improve testing efficiency.
