Description
Technical field
The present invention relates to LED test fixture technical field.
Background technology
Because three look paster LED device sizes are little, pin arrangements gap is little, when test, should ensure to electrically contact good, accurately locate again, current existing test fixture, generally adopt and two-wayly on 5mm insulating material fix three copper electrodes with screw is each, keep in touch by copper sheet self elasticity and LED electrode, three look paster LED device both sides pins are less than 1mm, gap only has 0.6mm, existing fixture is because space is little, the gib screw of each electrode distributes far away, it is long that copper electrode can only do, the accuracy of location is affected, elastic force is also inhomogeneous, use after a period of time, position and elasticity all can change, there is the phenomenon of loose contact, cannot ensure proper testing.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of three look paster LED device test fixtures, ensure the reliability of test position fix precision and contact from structure, can ensure that test result meets the requirements of stability, repeatability and consistance, and there is longer serviceable life; Sample simple and fast is changed in operation, can significantly improve testing efficiency, and can ensure the consistance of test result.
For solving the problems of the technologies described above, the technical solution used in the present invention is: three look paster LED device test fixtures, comprise tube-like envelope, and the inside of shell is fixed with two insulation catch, between two insulation catch, is provided with the first electrode and the second electrode; The first electrode is fixedly connected with two insulation catch; The second electrode is connected with the rotating shaft of two insulation catch; Between the second electrode and shell, be provided with back-moving spring, and be fixed with push rod on the second electrode; The outer end of push rod extends to housing exterior from the perforate of shell; The electrode slice composition that described the first electrode and the second electrode equate with the pin widths of three look paster LED devices by three thickness; The spacing of adjacent electrode sheet equates with the spacing of the adjacent pin of three look paster LED devices; The top in the vertical direction of each electrode slice is equipped with the recess coordinating with the pin of three look paster LED devices.
As the preferred technical solution of the present invention, between the adjacent electrode slice of three look paster LED device test fixtures, be connected with the insulation intermediate plate that the spacing of the pin that thickness is adjacent with three look paster LED devices equates.
As the preferred technical solution of the present invention, the angle between base and the side of the recess of three look paster LED device test fixtures is 80 ° to 60 °.
As the preferred technical solution of the present invention, the insulation catch of three look paster LED device test fixtures has and is provided with the V-type limited mouth that the second electrode rotates.
The beneficial effect that adopts technique scheme to produce is: the structure 1, contacting with pin by elastic electrode sheet from traditional LED device test fixture is different, the mode that the present invention adopts electrode slice directly to contact with pin, and by back-moving spring, pin is reliably contacted with electrode slice, and after long-time use, the wearing and tearing of electrode slice are low.2, the mode that adopts push rod to be combined with back-moving spring, clamps three look paster LED devices, can ensure to contact with the reliable of electrode slice, can discharge fast again, has improved test efficiency.3, three look paster LED devices are placed in the inside recess of side, can make three look paster LED devices fixing more firm on fixture.
