Acousto-optic electrical measuring clamp

Abstract

The invention relates to a device integrating an electrical measuring tool and a small shearing screwdriver tool for indicating voltages. An acousto-optic electrical measuring clamp is composed of a clamp body and an insulation handle, a screwdriver opening and an electrical measuring live wire end are arranged on the front end metal portion of the clamp body, a ground wire end which is in contact with a human body is arranged on the insulating handle of the clamp body, and a luminous device or a sound production device is arranged between the live wire end and the ground wire end. A luminous element and a luminous circuit for allowing the luminous element to work are arranged in the luminous device, and a sound production element and a sound production circuit for allowing the sound production element to work are arranged in the sound production device. The luminous device, the luminous circuit allowing the luminous element to work, the sound production device and the sound production circuit allowing the sound production element to work are all arranged on the insulation handle, a metal pointed nose clamp opening is changed into the screwdriver opening, and the device has multiple purposes. The device integrates the clamp body, an electric measuring pen and the small screwdriver tool, and is novel, applicable, passive, free of a battery, and capable of being permanently used.

Description

technical field [0001] The invention relates to a device integrating an electric testing tool and a cutting tool for indicating the existence of voltage, in particular, an acousto-optic electric measuring pliers. Background technique [0002] At present, the known structure of the electric measuring pen is composed of a test contact, a current limiting resistor, a neon tube, a metal spring and a hand electrode connected in series. Put the test contact in contact with the object under test, and touch the hand electrode with human hands. When the object under test has a higher voltage than the ground, the neon tube will light up, indicating that the object under test is charged. However, the purpose of the electrometer is single, and the general electrometer only emits light and does not make a sound; and the current pliers are only used for clamping or cutting, and there is no pliers that can indicate the existence of the measured voltage.
