Abstract

The invention discloses a circuit board carbon ink resistance testing device, which comprises a multimeter body, wherein the surface of the multimeter body is provided with an inserting hole, an inserting block is inserted into the inner wall of the inserting hole, a cavity is formed in the inserting block, the inner wall of the cavity is slidably connected with a sliding block, a first spring isfixedly mounted on the surface of the sliding block, a limiting block is fixedly connected to the surface of the sliding block, one end of the limiting block penetrates through the surface of the inserting block, a round cover is fixedly connected to the surface of the inserting block, a protective shell is arranged on the surface of the multimeter body, a bearing is fixedly connected to the surface of the protective shell, a handle is fixedly connected to the inner wall of the bearing, and a first anti-collision strip and a second anti-collision strip are fixedly installed on the surface of the multimeter body. By arranging the inserting block and the round cover, when the inserting hole is not used, the inserting hole can be sealed conveniently, so that the purpose of dust prevention isachieved, and use of the inserting hole is facilitated.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a circuit board carbon ink resistance testing device. Background technique [0002] Multimeters, also known as multimeters, multimeters, three-meters, multimeters, etc., are indispensable measuring instruments in power electronics and other departments. Generally, the main purpose is to measure voltage, current and resistance. [0003] At present, the carbon ink resistance of the existing circuit board is tested by a multimeter, but the jack of the existing multimeter has no dust-proof device, and dust is easy to fall into it, resulting in poor contact of the test line connector, and the multimeter has no protection device , resulting in inconvenient use, so in view of the above problems, a circuit board carbon ink resistance testing device with a jack dustproof device and a protection device is proposed. Contents of the invention [0004] The purpose of the present inv...
