Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0017] As shown in the figure, a buffer device for testing TV card boards includes a pressing platen 4 on which a plurality of plum blossom pin holders 2 corresponding to the pressing position of the test circuit board are detachably arranged. The plum blossom needle base 2 is covered with telescopic pressing pins 3 that can be compressed when pressing against the circuit board. In addition, it also includes a tray base 1 for supporting the TV card board. On the tray base 1, there are multiple telescopic pressing pins 3 The corresponding through hole 5.

[0018] In this way, the circuit board to be tested is placed on the tray base, and the telescopic pressing pins pass through the tray base and are placed on the circuit board, so that each telescopic pressing pin is directly facing the test contacts on the circuit board. Then press the circuit board by the pre...

Abstract

The invention discloses a buffer device for testing TV card boards. The buffer device comprises a pressing platen, a plurality of plum-blossom needle seats are detachably arranged on the pressing platen and correspond to tested circuit board abutting positions, and the plum-blossom needle seats are sleeved with extensible press needles which can be pressed when abutting a tested circuit board; the buffer device further comprises a tray seat for supporting the TV card boards, and a plurality of through holes corresponding to the extensible press needles are formed in the tray seat. The buffer device for testing the TV card boards is simple in structure, can make well contact with contacts of the circuit board and simplifies personal operations.

Description

【Technical field】 [0001] The invention relates to a buffer device for testing a TV card board. 【Background technique】 [0002] The current TV boards have to undergo a performance test before leaving the factory to ensure that each TV board is functioning normally and can be used. However, the currently used test fixtures are operated by manpower. It takes a long time to replace the testing platform and the efficiency is low. Employees can only operate one fixture for testing. The operation is complicated and the operator is prone to fatigue. Therefore, a tester independently developed by the applicant, and the present invention is a part of the tester. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a buffer device for testing TV card boards with simple structure, good contact with circuit board contacts, and simplified personnel operation. [0004] For above-mentioned purpose, the present ...
