Abstract

The invention discloses a direct current/direct current (DC/DC) power supply test fixture. The DC/DC power supply test fixture comprises a primary fixture, wherein the primary fixture is connected to a test instrument or system through a wiring terminal behind the primary fixture; a secondary fixture, which is connected with the primary fixture through an inserting needle and a jack of a crown spring structure in a matched manner, is arranged on the primary fixture; a fixing device for fixing a tested power supply product is arranged on the secondary fixture; the fixing device comprises a bearing platform, a horizontal fixing mechanism and a vertical fixing mechanism; the bearing platform is used for placing the tested power supply product; the horizontal fixing mechanism is used for fixing the horizontal direction of the power supply product; and the vertical fixing mechanism is used for fixing the vertical direction of the power supply product. The invention relates to a thick film DC/DC power supply and a manual test system fixture of a filter product, which can be used for performing metallic packaging on thick film DC/DC power supply series products of glass insulators. When the DC/DC power supply test fixture is used, the variety to be tested is convenient to exchange, test efficiency is greatly improved, the glass insulator is protected to the maximum degree, and product failure is reduced.

Description

[0001] technical field [0002] The invention relates to a thick film DC / DC power supply test fixture. [0003] Background technique [0004] At present, each thick-film DC / DC power supply is made by the designer or tester by himself, lacking a standardized design, with different board materials, sizes, and forms, and poor life and strength; there are various types of plugging and locking. Fixed pin insertion mode, free pin insertion mode, universal socket mode, zero insertion force socket and other forms apply different degrees of axial and radial force to the product pins, the state is uncontrollable, and it is easy to cause damage to the glass insulator. Every time a power supply is tested, the corresponding test fixture needs to be replaced, and various input and output lines must be reinstalled and connected, which is very cumbersome, affects efficiency, and is prone to errors and damages the product. [0005] Contents of the invention [0006] In order to overcome...
