Description

Technical Field

[0001] The utility model relates to the technical field of surface resistance shielding, in particular to a shielding device for a surface resistance tester. Background Art

[0002] During the use of the surface resistance shielding device, it is usually necessary to place the items to be shielded on an insulating board. Over time, stains will adhere to the insulating board, affecting its use. Since the insulating board is set at the bottom of the shielding box, it is inconvenient to take the insulating board out of the shielding box after disassembling it.

[0003] The existing patent (Announcement No.: CN216117794U) proposes a surface resistance tester shielding device, a tester shielding box, a protective cover is installed on the upper part of the tester shielding box, a test button is installed inside the protective cover, a transparent test observation window is installed on one side of the test button, a tester placement slot is arranged on the upper part of the inside of the tester shielding box, and a shielding protection block is installed on one side of the placement slot. The utility model is provided with a shielding protection block, and when measuring and connecting external wires, the protective pad can play a good protective role on the wires and the terminal heads, and the rubber insulation protection material and the insulation layer film can insulate and heat-insulate, ensure good electrical insulation, and can well shield external interference, thereby ensuring the stability of the surface resistance tester and effectively reducing the error of the measurement result.

[0004] The above-mentioned surface resistance shielding device adopts the technical solution of setting up a shielding protection block to solve the problem of reducing measurement errors. When measuring and connecting external wires, the protective pad can provide good protection for the wires and terminal heads. The rubber insulating protective material and the insulating layer film can provide insulation and heat insulation. The problem with this solution is that although it solves the problem of reducing measurement errors, it does not solve the problem that the insulating board is inconvenient to remove during disassembly. Therefore, we propose a surface resistance tester shielding device to solve the above problem. Utility Model Content
