Embodiment Construction

[0052] In order to solve the technical defect in the prior art that shifting operation is required when performing various tests, which makes the operation inconvenient for users, the present invention provides a tester with easy operation and a test circuit inside the tester. The following will be introduced through specific embodiments.

[0053] The invention provides an electric test pen, which includes a pen body 1 , a test needle 2 , a light emitting tube 3 , an electric wire 4 and an alligator clip 5 . The test needle 2 is set at one end of the pen body 1, and the light emitting tube 3 is set at the other end of the pen body. The alligator clip 5 is connected with the pen body 1 through the wire 4 . A detection circuit is arranged inside the pen body 1 . The test pen in the present invention has a simple structure, and the load can be detected through the test pin. When detecting the load, it is mainly realized through the internal detection circuit. The principle of...

Abstract

Provided are an electroprobe and a test circuit thereof. The invention relates to a probe and a test circuit thereof, the electroprobe comprises a probe body, a test needle, a light-emitting tube, anelectric wire and a crocodile clamp; the test needle is arranged at one end of the pen body, the light-emitting tube is arranged at the other end of the pen body; the crocodile clamp is connected withthe pen body through the electric wire; and the inner part of the pen body is provided with a detection circuit. Compared with the prior art, a plurality of functions, including the loop conduction,the voltage level, and the voltage measurement of the positive pulse and the negative pulse, can be detected through the test needle, and the electroprobe is simple in use and is free of level shifting. The electroprobe is convenient to use and high in judgment, can determine whether a broken circuit, a loop or a voltage is in the tested point in the circuit, and also can determine the short circuit, the positive pulse, the negative pulse, or a state where the car battery is charged. Moreover, the battery in the probe body can be charged in the test.

Description

technical field [0001] The invention relates to an electric test pencil, in particular to an electric test pencil capable of multiple testing functions; the invention also provides a test circuit for the electric test pencil. Background technique [0002] The test pen is also called the test pen, referred to as "electric pen". It is an electrician's tool used to test whether there is electricity in the wire. In the application of the existing electric test pen, it is also often used in the detection of the battery of the car. [0003] see figure 1 , which is a structural schematic diagram of a test pencil in the prior art. Existing test pens include: test needle 1a, penholder 2a, light bulb 3a, spring 4a, lead wire 5a and alligator clip 6a. The light bulb 3a is arranged inside the penholder 2a, the test needle 1a is arranged at the end of the penholder 2a, and one end of the test needle is arranged inside the penholder, and is connected to the inner end of the penholder ...
