The invention discloses an electronic and electrical anti-noise device in the technical field of electronic and electrical testing devices. The device comprises a sealing mechanism which is internally provided with a moving mechanism, and the moving mechanism is provided with a clamping mechanism. The sealing mechanism comprises a sealing bottom plate, a sealing support is fixedly installed on the sealing bottom plate, sealing baffles are fixedly installed on the three side faces and the top face of the sealing support, a sealing door is hinged to the end of the other side face of the sealing support, a sealing door upper magnet is fixedly installed on one side of the top of the sealing door, and a sealing door sealing strip is arranged on the end face of the sealing door. By arranging the sealing mechanism, the sealing baffle, the sealing door and the sealing inner partition plate are made of composite sound insulation plates, the two ends of the exterior of each composite sound insulation plate are steel plates or wood plates, the interior of each composite sound insulation plate is sequentially composed of sound insulation felt, polyester fiber cotton, a gypsum plate and egg cotton, and all the materials are used in cooperation. And the anti-noise performance can be greatly improved.
Description
technical field [0001] The invention relates to the field of electronic and electrical testing equipment, in particular to an electronic and electrical noise prevention device. Background technique [0002] Electrical and electronic, a general term for electrical components or devices that are wholly or mainly composed of electronic devices and electronic circuits. Such as proximity switches, transistor temperature relays, synchronous contactors, etc. In signal detection, fault monitoring and protection, etc., the priority is to realize electronicization, while the operation of switching on and off the strong current is mostly completed by contact appliances. pole type transistor to complete. [0003] Due to the wide variety of parts and components of the electronic and electrical devices, the use or testing needs to be performed under the effect of silence, and there is a lack of an electrical and electrical noise prevention device in the prior art.
