Novel test pencil

Abstract

The invention discloses a novel test pencil, and belongs to the field of electronic detection equipment. The novel test pencil comprises an insulating handle and a testing device; a cavity is formed in the insulating handle; a hand touch resistor, a current limiting resistor, a neon tube and a compressing spring which are sequentially connected are arranged in the cavity; an opening is formed in one end of the insulating handle; a protecting cover is arranged at one side of the opening; a clamp is arranged on the protecting cover; the protecting cover is hinged to the insulating handle; a first groove detachably connected with the clamp is formed in the other side; the testing device comprises a testing rod and a test contact; the testing rod is connected with the compressing spring; the diameter of the testing rod is less than that of the opening; a second groove detachably connected with the clamp is formed in the testing rod; the test contact is pointed; the insulating handle is of a concave structure and manufactured from a transparent material. The novel test pencil is simple and reasonable in structure, and convenient to operate; the test contact can be protected; the carrying is convenient.

Description

technical field [0001] The invention relates to the field of electronic detection equipment, in particular to a novel test pencil. Background technique [0002] With the advancement of science and technology, the development of the electronics industry involves various fields of society. Electronic products play an important role in our daily life. With the increase of electronic products, the detection amount of electronic products is also increasing. Playing the role of testing equipment, it is a commonly used tool in the production and testing of electronic products. The general test pen has a simple structure, and there are many inconveniences in the practical process. The pointed contacts are exposed outside, and it is extremely inconvenient to carry. It is easy to hurt people and not fall-proof. For this reason, we have designed a new type of test pencil that is easy to hold, carry and drop-proof.
