AI Technical Summary

Technical Problem

In existing power supply equipment, the cable is difficult to install on housings with insufficient surface space or small size, which makes it impossible for the cable harness fixing device to effectively fix the external power cable.

Method used

The wiring harness fixing device includes a fixing member and a strap. The strap is installed on the housing through the fixing member, wrapped around the outside of the external power cord, and prevents movement by friction. The fixing member is connected to the housing or handle to avoid occupying the surface space of the housing.

Benefits of technology

It enables the secure fixing of external power cables even when there is insufficient space or the size of the housing surface, reducing the number of parts and saving assembly processes and time.

Abstract

This application relates to the field of power supply technology, specifically to a power supply and power supply system. The embodiments of this application aim to solve the problem of the difficulty in installing the harness onto a housing. The power supply provided in this application has a power interface that extends from inside the housing through the housing and protrudes outwards. The power interface is used for electrical connection with an external power cord. A harness fixing device is located outside the housing and includes a fixing member and a harness. The fixing member is fixedly connected to the housing. A first end of the harness is fixed to the fixing member, and a second end of the harness is wrapped around the periphery of the external power cord and used to hold the external power cord. The harness is installed on the fixing member rather than directly on the housing. The harness fixing device is less restricted by the surface space of the housing during installation; even when the surface space of the housing is insufficient, the harness fixing device can still be installed on the housing.
