Electric appliance, wire passing rubber ring and electric cabinet

Abstract

The invention relates to a wire passing rubber ring. The wire passing rubber ring is in a hollow frustum shape; a connecting part adaptive to a wire passing hole is arranged on the large end of the wire passing rubber ring; a cutting part with rubber ring holes of different diameters can be formed by cutting the position, located from the large end of the wire passing rubber ring to the small end of the wire passing rubber ring, of the side wall. In actual process of installation, the cutting part of the wire passing rubber ring can be appropriately cut aiming at wires of different diameters, and the cut rubber ring holes can be tightly matched with the wires all the time, so that the wire passing rubber ring has very good universality; the problem that the gap between an existing wire passing rubber ring and the wires is too large is solved, the potential safety hazard is eliminated, and the leakproofness and protection level of a device are effectively improved. The invention further discloses an electric appliance and an electric cabinet, and the electric appliance and the electric cabinet are provided with the wire passing rubber rings.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a thread-passing rubber ring. Background technique [0002] The power lines of electrical appliances or electric control boxes need to pass through the shell. Take the electric control box in the air conditioning unit as an example. Generally, the inlet holes for power supply lines on the electric control box are round holes or square holes. The power cord protective rubber ring matched with this hole is also correspondingly circular or square. [0003] However, due to errors in the production process, a very suitable match cannot be achieved between the protective rubber ring and the power cord, and there is often a large gap between the power cord and the protective rubber ring after assembly, which leads to the protection The apron is very easy to fall off, or the power cord will be damaged due to long-term friction between the power cord and the pr...
