Description

Technical Field

[0001] The utility model relates to the field of weak current engineering, in particular to a weak current engineering detector. Background Art

[0002] There are two main types of weak current: one is low-voltage electricity such as the safety voltage level and control voltage specified by the state, which is divided into AC and DC, mainly including AC below 36V and DC below 24V, such as 24V DC control power supply, or emergency lighting backup power supply; the other is information sources carrying voice, image, data and other information, such as telephone, television, and computer information. The equipment used to detect weak current is a weakness detector.

[0003] Weak current engineering is a classification of power application. Power application can be divided into two categories: strong current and weak current according to the strength of power transmission. When a short circuit or fault occurs in a weak current line, maintenance personnel will use a detector to detect the line to find the fault point. However, most of the weak current detectors in the prior art lack protective mechanisms when in use, and cannot protect and store the detector and the test pen well. In addition, the weak current wires are directly inserted into the interface of the equipment, making some weak current wires easily loosened by external pulling, thereby causing some connections to be easily damaged.
