Abstract

The portable wifi repeater electric wire disclosed in the present invention is composed of a compact case for portable use, an lcd for indicating the voltage and current wifi state, and a magnetic plug which is automatically disconnected when the electric wire is pulled by a physical impact .
Such a portable wifi repeater electric wire rewires the electric wire with the magnetic plug, draws out the required length, checks the local voltage and wifi status at the destination, prevents the equipment from malfunctioning, amplifies the wifi signal if necessary It is effective to use various computer equipment and smart devices smoothly.

Description

USB charger and wifi repeater including USB charger and wifi reporter include wire rill}

The present invention relates to a portable electronic device, and more particularly to a smart device and a notebook, in which a user using a thick cable is used for a general purpose application in order to use a low power device, To a portable multi-wire which is secured with a built-in microcomputer and a display device that can measure voltage and current using a thin cable with a low square to use less than 200 watts of electricity.

The present invention relates to a portable electric wire, more specifically, a wire is wound, a necessary length is drawn out and used, and an attached LCD and a LED are used to grasp the voltage and current situation of each area, To a device that prevents damage to the equipment at the destination by comparing it with the range.

Generally, it is possible to supply electric power far away from the power source by making the wire wound on the winding or the like to be loosened for a long time. After the use, the wire can be easily wound by winding the wire.

However, since conventional cable reels do not use a multi-tap for a short distance, the use of a long wire and a wire capable of withstanding a high ampere has made it impossible for a person to carry it at all times.

Especially, as the penetration rate of smartphones, smart tabs, laptops and other equipments is getting higher, it is necessary to place a seat close to an outlet that can be used when visiting the cafes, There is an inconvenience such as confirmation from time to time.

In addition, when the equipment is connected to the adapter through a wire reel and a shock is applied to the feet of a moving person, the comparatively light smart device and the notebook are swept away, causing damage to the device, There is a risk that the connection terminal to be connected is damaged.

The object of the present invention is to solve the problems of the prior art as described above, and it is an object of the present invention to provide a compact case in which a wire is housed in a compact case and taken out by a required length, It has a high-speed usb charging port with a relatively high frequency of use, and is an electric wire using a cable including a magnetic terminal that is separated during a shock.

In the present invention as described above, the former electric wire requires connection of industrial equipment and a variety of equipments, so that it is impossible to carry using thick wires of a certain square or more. This product is designed to be a compact case for maximizing portability. It is equipped with USB charging port and wifi repeater, which are widely used in smart devices, It is possible to check the voltage state before connecting the device to be used, so that the damage of the connecting device can be prevented in advance.

Fig. 3 is a cross-sectional view showing a surface for winding a wire and a device for winding and fixing the wire
4 is a block diagram of a multi-channel wifi antenna built in a case
5 is a cross-sectional view of a magnetic terminal that is automatically separated from the impact.

The present invention has the following features in order to achieve the above object.

This invention features techniques and designs to reduce the absolute volume for portability when carrying a wire for the use of electricity in travel and public transport.

The electric wire 3 housed in the main body can be reduced in absolute volume by using a thin electric wire capable of driving equipment of less than 200 W at maximum and using a detachable power plug 2.

In order to prevent damage to the product due to heat generation and heat generated when the maximum allowable current value is exceeded, when a device with a built-in microcomputer and exceeding the maximum permissible current value is connected, the microcomputer detects the red Flashes quickly and warns the user by ringing a buzzer (code 2).

When the user of the present invention uses the product outside of the country, the voltage measured by the microcomputer is displayed on the LCD 7 and can be confirmed from a distance through the color of the LED 7-1. Therefore, can do.

The LED (7-1) also functions as a tester to judge the connection failure of the magnetic terminal or the power supply of the socket because the socket is not turned on when the socket is not turned on.

This design reduces the absolute volume of the electric wire, and it incorporates a USB charging terminal (reference numeral 8) for charging the smart device, so that it does not carry a separate charger, Can be used.

The magnetic terminal mounted at the end of the main body is attached to the magnetic stopper (3-1) attached to the main body when the power cable is housed to prevent the cable from being loosened while moving.

The microcomputer included in the present invention detects a wifi signal, detects a wifi signal and a free wifi signal designated by the user, and displays the wifi signal and the free wifi signal on the LED 7-1 and the lcd 7, thereby facilitating the use of the Internet through a smart device.

In order to maximize the performance of the WiFi function included in this design and to prevent the addition of additional parts, antennas (6, 6-1, 6-2) with different frequency bands are individually mounted inside the body.

1: Connection terminal for connecting AC equipment
2: Disconnected AC plug receptacles and buzzer
3: The form in which the wire is housed
3-1: Magnetic stopper for fixing the stored wires
4: Magnetic terminal separated by impact
5: Cross-section of magnetic terminal diagram separated by impact
6: Built-in multi-channel wifi antenna 1
