New multimeter

Abstract

An embodiment of the invention discloses a new multimeter, wherein the positive and negative pen jacks of the multimeter main body are respectively equipped with head assemblies; the head assemblies comprise a test lead, a terminal hollow pen head, a terminal solid pen head, an aviation cable pen head and a grounding clip; the test lead comprises a lead body, a socket connector and a plug connector; the lead body comprises a lead metal core and a lead insulation outer cover; the socket connector comprises a socket connection terminal and a socket terminal insulation outer cover; the plug connector comprises a plug connecting terminal and a plug terminal insulation outer cover; the terminal hollow pen head comprises a hollow pen head connecting terminal and a hollow pen head terminal insulation outer cover; the terminal solid pen head comprises a solid pen head connecting terminal and a solid pen head terminal insulation outer cover; the aviation cable pen head comprises a cable pen head connecting terminal and a cable pen head terminal insulation outer cover; and the grounding clip comprises a grounding clip insulator, a grounding clip connecting terminal and a grounding clip contact piece. The new multimeter provided by the invention has the advantages of novel design and convenient use.

Description

Technical field [0001] The invention relates to the technical field of multimeters, in particular to a new-style multimeter. Background technique [0002] A multimeter is an electrician's tool that is used very frequently, and it can be said to be a must-have for electricians. The current multimeter has only two universal test leads, and the test leads of the test leads are immutable. [0003] It should be pointed out that since the multimeter has only two universal test leads, in the operation and maintenance of the automatic circuit breaker on the distribution network column, when the multimeter is required to measure the voltage or the on-off measurement, two hands are required during the measurement process. Hold the tip of the meter pen. When other operations are needed, it can’t be done. It can only be assisted by a second staff member. However, because two people use insulated ladders to work on the poles, there is a greater safety risk. ; And because of the narrow space o...

Problems solved by technology

[0003] It should be pointed out that since the multimeter has only two general-purpose test wires, in the operation and maintenance of the automatic circuit breaker on the distribution network column, when it is necessary to use the multimeter to measure voltage or on-off measurement, two hands are required during the measurement process. Holding the tip of the test lead, when other operations are required, it cannot be carried out. It can only be assisted by a second worker. However, since two people use an insulating ladder to work on the pole pole, there is a greater safety risk. ; and due to the narrow space of the automatic switch control box on the distribution network post, it is not conducive to two people working at the same time
