Description
Technical field
The present invention relates to LED test fixture technical field.
Background technology
Owing to trichroism paster LED device size is little, pin arrangements gap is little, should ensure during test that electrical contact is good, it is accurately positioned again, current existing test fixture, typically use on 5mm insulant that two-way screw is each fixes three copper electrodes, keep contacting with LED electrode by copper sheet natural resiliency, trichroism paster LED device both sides pin is less than 1mm, gap only has 0.6mm, existing fixture is little due to space, the fixing screw of each electrode is distributed farther out, it is long that copper electrode can only do, the accuracy of location is affected, elastic force is the most uneven, after using a period of time, position and elasticity all can change, the phenomenon of loose contact occurs, proper testing cannot be ensured.
Summary of the invention
The technical problem to be solved is to provide a kind of trichroism paster LED device test fixture, the reliability of test position fix precision and contact is ensure that from structure, ensure that test result reaches the stability of requirement, repeatability and concordance, and there is longer service life；Sample simple and fast is changed in operation, it is possible to significantly improves testing efficiency, and can guarantee that the concordance of test result.
For solving above-mentioned technical problem, the technical solution used in the present invention is: trichroism paster LED device test fixture, and including tube-like envelope, the inside of shell is fixed with two panels insulation catch, is provided with the first electrode and the second electrode between two panels insulation catch；First electrode is fixing with two panels insulation catch to be connected；Second electrode is connected with two panels insulation catch rotating shaft；It is provided with between second electrode and shell on back-moving spring, and the second electrode and is fixed with push rod；The outer end of push rod extends to housing exterior from the perforate of shell；Described first electrode and the second electrode are formed by the electrode slice that three thickness are equal with the pin widths of trichroism paster LED device；The spacing of the adjacent pin of the spacing of adjacent electrode sheet and trichroism paster LED device is equal；The top in the vertical direction of each electrode slice is equipped with the recess that the pin with trichroism paster LED device coordinates.
As the preferred technical solution of the present invention, between the adjacent electrode slice of trichroism paster LED device test fixture, connect the insulation intermediate plate having the spacing of pin that thickness is adjacent with trichroism paster LED device equal.
As the preferred technical solution of the present invention, the angle between base and the side of the recess of trichroism paster LED device test fixture is 80 ° to 60 °.
As the preferred technical solution of the present invention, the insulation catch of trichroism paster LED device test fixture has and is provided with the V-type limited mouth that the second electrode rotates.
Use and have the beneficial effects that produced by technique scheme: 1 is different with the structure that traditional LED component test fixture contacts with pin by elastic electrode sheet, the present invention uses the mode that electrode slice directly contacts with pin, and make pin and electrode slice reliable contacts by back-moving spring, and after long-time use, the abrasion of electrode slice is low.2, the mode using push rod to be combined with back-moving spring, clamps trichroism paster LED device, both can guarantee that the reliable contacts with electrode slice, and can quickly discharge again, improve test efficiency.3, during trichroism paster LED device is placed on the inside recess of side, trichroism paster LED device can be made fixing more firm on fixture.
