[0002] The adapter board is a multi-layer printed circuit board installed at the bottom of the chassis. The adapter board will be corroded and short-circuited during long-term salt spray use. In order to test the reliability of the function and appearance of the TP product under power-on conditions , it needs to be tested in salt spray, and during the salt spray test, the salt spray temperature and humidity of the internal environment will cause the adapter board to corrode and cause a short circuit, which will affect the use of TP products under normal power on, and may be damaged due to the transfer The short circuit on the board leads to damage to the TP product, which eventually leads to the inability of the product to perform periodic tests under a completely good power-on condition, which affects the final reliability test effect of the TP product and cannot achieve the test goals expected by the experimenters.

Abstract
The invention provides a device for preventing corrosion and short circuit of an adapter plate in a TP reliability power-on test. The device comprises a salt spray test box and an adapter plate sealing protection box, wherein the salt spray test box is disposed on the outer side of the adapter plate sealing protection box; the adapter plate sealing protection box is of a cubic structure defined bya cover plate, a baseplate and side plates, a cover chamfer is formed in the periphery of the face, adjacent to the side plates, of the cover plate, and a sealing strip is disposed in the cover chamfer and corresponds to the side plates. The device is designed reasonably, the adapter plate sealing protection box isolates the temperature and humidity in the salt spray test box, an independent temperature environment and a humidity environment are provided for a salt spray test system, and the tested adapter plate can work under normal temperature and humidity conditions.
Description
technical field [0001] The invention relates to a protective device, in particular to a short-circuit device for preventing corrosion of an adapter plate for TP reliability electrification test. Background technique [0002] The adapter board is a multi-layer printed circuit board installed at the bottom of the chassis. The adapter board will be corroded and short-circuited during long-term salt spray use. In order to test the reliability of the function and appearance of the TP product under power-on conditions , it needs to be tested in salt spray, and during the salt spray test, the salt spray temperature and humidity of the internal environment will cause the adapter board to corrode and cause a short circuit, which will affect the use of TP products under normal power on, and may be damaged due to the transfer The short circuit on the board leads to damage to the TP product, which eventually leads to the inability of the product to perform periodic tests under a complet...
