Description

Power cable with identification function

The present invention relates to a power cable, and in particular, when the identification switch is operated on one of both sides of the power cable in an on state, the identification light can be displayed through the light emitting unit on the other side, and furthermore, the identification sound through the buzzer part. By configuring so that this can occur, it is possible to easily and clearly identify whether both sides of the power cable are both sides of the same power cable, and thus the time required to find a power cable that is connected to an electronic product or various equipment to supply power. , Effort and cost can be saved, and furthermore, it is equipped with an identification function that prevents unexpected accidents and losses due to incorrect disconnection and connection of power cables that are connected to electronic products or various equipment to supply power. It is about a power cable.

Power cables are used to supply power to various electronic products or various equipment. Specifically, the existing commercial power cable connects between a commercial power outlet and the various electronic products to directly supply power to the various electronic products, or, as shown in FIG. 1, the existing commercial power cable ( 1) is used to supply power to the various electronic products by connecting between the multi-outlet 200 or the power distributor 300 and the various electronic products.

When using various electronic products and it is not easy to identify which electronic product the power plug used in the multi-outlet is the plug-in used, the cause of failure or inconvenience may be caused by unplugging other plugs when relocating a computer or expanding or maintaining additional equipment. There is a problem that can be caused.

At home, multi-outlets are installed on a corner floor for aesthetic reasons, and the multi-outlets are far away from computers, printers, monitors, and TVs, which are commonly used electronic products, and all commercial power cables (1) used are difficult to identify with each other. Since it is made of black, it is not possible to simply and accurately identify the plug of the power cable connected to a specific electronic product, and this causes a problem that requires a lot of time, effort, and cost during maintenance, extension, and relocation.

In addition, as shown in Fig. 2, when used in an industrial site or a computer room, power cables are generally used unorganized (refer to Fig. 2 (a)) or tied to an equipment rack with cable ties for line arrangement. Is (see Fig. 2(b)). However, even in the latter case, since the process of finding the corresponding power cable by loosening the cable tie straps is required, a lot of time and effort is required, and after the work is finished, the process of restoring and arranging the cables again has to be repeated. In this case, unnecessary time, effort, and cost are required.

If various equipment such as used electronic products or hubs are abnormally terminated or the power plug in operation is pulled out, the electronic products, etc., are broken or data is blown away, furthermore, the network connection is disconnected and errors occur. There is a problem that a loss occurs.

Conventionally, as a way to easily find the connected power cable, Korean Utility Model Registration No. 20-0278823 and Korean Utility Model Registration No. 20-0317843 use a method of fastening a name tie to the power cable and attaching a sticker. However, these existing methods have a problem in that the name cannot be recognized as the prints accumulate and erase dust over time, and during maintenance, the power plug is not inserted into the corresponding outlet, but is inserted into a convenient empty outlet at the discretion of the operator. It has a disadvantage that the effectiveness is poor as it becomes useless and does not achieve the purpose of attaching the sticker.
