Lead fixing device, electric appliance box and electric appliance

Abstract

The invention relates to a lead wire fixing device, which includes a wire fixing device body and a fitting. The wire fixing device body includes an accommodation cavity for accommodating the fitting. Both ends of the wire fixing device body are respectively provided with openings that communicate with the accommodation cavity. The wire fixing device body also includes a supporting surface as a side wall of the accommodating cavity, so that the fittings move closer to each other or toward the side wall of the accommodating cavity opposite to the supporting surface, thereby forming a fixed position for clamping the lead wire. When the lead wire passing through the lead wire fixing device is pulled by an external force in one direction, the support surface gives the fitting a support force perpendicular to the support surface, and the component force in one direction of the support force can be balanced with the aforementioned external force. The component force in the other direction is towards the clamped lead wire, clamping the lead wire, so that the lead wire will not be pulled in one direction under the pulling of the external force, and the effectiveness of the connection between the lead wire terminal and the electrical components in the electrical box is protected. Also provided are an electrical box and an electrical appliance.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a lead wire fixing device, an electrical box and an electrical appliance. Background technique [0002] In the prior art, the power cord of the electrical appliance is connected to the electrical box through the terminal, so as to realize the input of power. Wire fixing clip, so that the lead wire is drawn out through the wire fixing clip. Generally, the wire fixing clip includes two clips, and the two clips are fastened by screws to fix the leads. However, the reliability of this kind of clamp depends on the tightening degree of the screw, which is inconvenient to operate, low in installation efficiency, and prone to loose fastening, which makes the lead wires easily pulled by external forces, resulting in failure of the connection between the terminal and the electrical components inside the electrical box. . Contents of the invention [0003] Based on this, ...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to provide a lead wire fixing device, an electrical box and an electrical appliance that is easy to operate and has high reliability in fixing the wire, aiming at the problem that the existing lead wire is fixed by the wire fixing clip, which is inconvenient to operate and not fastened firmly.
