Description

Technical Field

[0001] The utility model belongs to the technical field of strong and weak current interference prevention, and in particular relates to a strong and weak current interference prevention device for an electric automatic control circuit. Background Art

[0002] Electricity applications can be divided into two categories: strong electricity and weak electricity according to the strength of the power transmission. Electricity used in buildings and building complexes generally refers to strong electricity of AC 220V50Hz and above, which mainly provides electricity to people and converts electricity into other energy sources, such as air conditioning, lighting, power, etc. There are two main types of weak electricity in intelligent buildings. One is low-voltage electricity such as the safety voltage level and control voltage stipulated by the state, which is divided into AC and DC, 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, images, data and other information, such as telephone, television, and computer information. Generally, during the indoor decoration process, tin foil is often used to wrap the intersection of strong and weak electric wires and pipes at the water and electricity stage. The purpose is to shield the electromagnetic radiation emitted by the strong electricity, that is, the 220-volt wire, and reduce interference with the signal line.

[0003] The existing method of using tin foil to wrap the intersection of strong and weak electric wires has the problem that the wires are suspended, and the electrons absorbed in the tin foil cannot be effectively grounded and discharged. There is a situation where the anti-interference effect needs to be enhanced. In addition, when there are many lines, the connectivity between the lines cannot be well guaranteed, which will occupy a larger line spacing and a larger space. Utility Model Content

[0006] Furthermore, the connecting member includes a hook rotatably connected to the side of the metal protection tube, and a plurality of hooks are provided on each side of the metal protection tube.

[0007] Furthermore, the connecting piece includes a rubber plug rod plugged into the bottom of the metal protection tube, and an elastic component is plugged into the end of the rubber plug rod away from the metal protection tube.
