Cable clamp with electric leakage pre-warning function

Abstract

The invention discloses a cable clamp with an electric leakage pre-warning function. The cable clamp consists of an upper metal clamp plate (1) with an upwards arched middle section and a lower metal clamp plate (2) with the top surface capable of fitting the bottom surface of the upper metal clamp plate (1) to form a through groove (3) for a cable to penetrate through, wherein two ends of the upper metal clamp plate (1) are detachably fixed to the top surface of the lower metal clamp plate (2) through connecting pieces (9); an electric leakage detection instrument (11) is further arranged on a side wall of the upper metal clamp plate (1) or the lower metal clamp plate (2); and a sound-light pre-warning lamp is electrically connected to the electric leakage detection instrument (11). According to the cable clamp, a sound-light alarm can be given in time during electric leakage of the cable to remind an electrician to perform power failure operation before maintaining the cable or make anti-electric-shock preparations, thereby greatly improving the maintenance safety of the electrician.

Description

technical field [0001] The invention relates to a cable installation, in particular to a cable clamp for early warning of electric leakage. Background technique [0002] During the installation and use of cables, cable clamps are often used to clamp the outer wall of the cable to fix its position. Existing cable clamps can only be used to clamp a single cable. If there are a large number of cables to be installed and fixed in a certain area, the cable clamps will also be consumed too much, causing waste and increasing costs; and too many cable clamps It will also cause serious damage to the installed area, such as walls and floors. However, when using the same clamp to clamp multiple cables at the same time, the outer walls of multiple cables are often squeezed together tightly. When the weather is hot, the cables become thicker due to thermal expansion and contraction, which makes the hard cable clamps longer. The time squeeze will cut the outer wall of the cable or even ...

Problems solved by technology

Existing cable clamps can only be used to clamp a single cable. If there are a large number of cables to be installed and fixed in a certain area, the cable clamps will also be consumed too much, causing waste and increasing costs; and too many cable clamps It will also cause serious damage to the installed area, such as walls, floors, etc.

However, when using the same clamp to clamp multiple cables at the same time, the outer walls of multiple cables are often squeezed together tightly. When the weather is hot, the cables become thicker due to thermal expansion and contraction, which makes the hard cable clamps longer. The time squeeze will cut the outer wall of the cable or even leak electricity, which will bring the risk of electric shock to the maintenance personnel during the cable maintenance process
