Description

[Detailed description of the invention] [Technical field of the invention] The invention is applicable to audio including radio, television,
This invention relates to a power cord holding device mainly used for consumer devices such as videos, communication devices, and other home appliances.

[Technical background of the invention and its problems]

Conventionally, many devices have been used as holding devices for power cords in device bodies. For example, an insulator such as a grommet or a cord clip is passed through the power cord and the insulator is engaged with an opening in the main body of the device.

The one using this grommet is the simplest and easy to attach to the main body, but it easily comes off from the main body when the cord is pulled. There are also cord grips that have a very strong holding force against tension in the cord, but they are difficult to attach to the main body and have drawbacks in workability.

In addition, a separation wall is provided inside the cord insertion part of the main body, and the power cord connected to the internal parts is made a U-turn with this separation wall in between, and the power cord is locked and then led out to the outside. be.

In this way, the cord latching portion can be integrally formed with the main body and is effective against tension of the cord, but there are still problems. In other words, it is fine if the main body is entirely made of an insulator such as synthetic resin, but if a conductor such as a steel plate is used for the back plate, safety standards prohibit direct contact of the conductor with the power cord. If the product is intended for countries such as the United States, some type of insulation measures are required.
Also, depending on the export destination region, it may be necessary to change the power cord to a thicker one than usual due to differences in voltage, etc., but if you set the cord holding part to be a thick cord in advance and set it to a larger size, it will be possible to When a cord is used, the cord dances around inside the product, impairing its reliability. Therefore, a dedicated cord holding section must be formed for each export destination region.

In addition, with conventional models, in many cases, the power cord is connected to the transformer etc. by soldering after the power cord is secured to the back plate of the main unit, so it is necessary to connect the power cord to the transformer etc. after the back plate is fixed to the main unit. Connection work is not possible and work efficiency is poor.

[Purpose of invention]

The present invention is an attempt to improve the above-mentioned points, and in a device that holds the cord by making a U-turn, the present invention takes into account insulation properties and is designed to be easily compatible with normal and thick cords. The purpose is to
