Abstract

The color, the tint, the bright, the sharpness and the contrast values (the picture value) for by channels are stored on a memory and the stored values are switched automatically when a channel is changed. The method comprises the steps of; (A) checking that the input signal is channel change key or the picture value change key; (B) sending channel switching signal to a tuner (60) to select the corresponding channel and sending the picture value of the corresponding channel to a video processor (50); (C) sending input picture value to the video processor (50) when input signal is picture value change key; and (D) storing the input picture value on a memory as a new picture value for the corresponding channel.

The present invention relates to an electric wire winding machine, and more particularly, to an electric wire winding machine which is capable of preventing an electric shock accident due to an earth leakage by grounding the conductive portion of the electric wire winding case. In general, the electric and electronic products are installed so that the wire for drawing the power from the outside to be drawn out, in the case of a mobile product such as a vacuum cleaner is equipped with a wire winding to house the wire wound inside. In general, all electrical and electronic products are grounded to prevent leakage current, that is, electric shock due to a short circuit. This is mostly through a ground terminal installed at an outlet using a three-wire wire having two wires and a single earth wire. Grounding is in effect. The wire winding machine for winding such wires is roughly classified into a manual type and an automatic type, among which an automatic wire winding machine is shown in FIG. As shown therein, a conventional electric wire winder is formed by a spiral spring (not shown) inside a case 1 having a cover 2 made of a metallic material with a reel (not shown) to which the electric wire 3 is wound. It is stored and stored so as to have elastic rotational power in one direction. At this time, a connecting device for transmitting power from the electric wire 3 wound on the reel to a circuit part of an electric and electronic product, that is, the two worst of the electric wire 3 Two power terminals 6 connected to the low-coil wire and one ground wire and the contact cord are installed so that one ground terminal 7 protrudes out of the cover 2 by a connecting plate 4 supporting them. do. And the tip of the genital electric wire 3 is provided with a plug 5 connected to the outlet with a pair of power supply terminals 6 'and a ground terminal 7', respectively.

The conventional wire winding machine configured as described above is fixedly installed in an electric / electronic product and connects the plug 5 to an outlet to supply power thereto, and at the same time, the leakage current that may be generated in a metal part, which is a conductor, may be provided. 3) is absorbed through the battery terminal (7) (7 ') and the ground terminal of the outlet connected to the ground wire of the user to prevent the electric shock accident accordingly, but the conductive portion of the wire winding case made of metal, namely Since the cover (2) was not grounded, there was always a risk of electric shock.

Accordingly, the present invention has been made to solve the problems described above, and the object of the present invention is to provide an improved electric wire winder so as to effectively prevent the risk of electric shock accidents caused by a short circuit by grounding the conductive part of the case. .

In order to achieve the above object, the present invention is provided with a connecting means including a foldable terminal to which the ground wire of the wire is connected to a case accommodating the reel to which the wire is wound, and at least a part of the case is exposed to the outside of the conductive material. In twisting the electric wire comprising a, it is characterized in that it is provided with a grounding means for connecting the conductive portion of the case with the ground terminal of the connection means.

This invention, the conductive cover of the wire winding case by the grounding means is connected to the ground terminal, so that an electric shock due to leakage current that can be generated through it is fundamentally prevented. Will be able to implement

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram showing the electric wire twister according to the present invention, (a) is a bottom recessed perspective view and (b) is a sectional view of the main part shown in (a), and FIG. 3 is another embodiment of the present invention As shown, (a) is a bottom view (b) excerpts sectional view.

First, as shown in FIG. 2, the wire twister according to the present invention includes a case 10 including a cover 20 formed of a metallic material with a reel (not shown) to wind the wire 30. It is stored and stored to have a resilient rotation force in a predetermined direction by a spiral spring (not shown), the cover 20 which is a conductive portion of the case 10 is fixed by a screw 90 to prevent the reel of the reel do. And a connection device for transmitting power from the electric wire 30 wound on the reel to electrical and electronic products, that is, two power terminals 60 connected to the power wire of the electric wire 30 and a ground wire. Ground terminals 70 are installed to protrude outward through the through-hole 21 formed in the central portion of the cover 20 by the connecting plate 40 holding them.

In addition, the front end of the wire 30 is provided with a plug 50 which is connected to the outlet, which has a pair of power terminals 60 'and ground terminals 70', respectively, and the cover 20 Grounding means for connecting it to the ground terminal 70 provided in the connecting plate 40 is provided. Here, the grounding means, the terminals 81 and 82 are respectively bound to both ends of the covering wire 80 having a predetermined length, the terminal 81 of one side through the coupling hole (81a) formed in the body It is fixed to the screw 90 for fixing the cover 20, the other terminal 82 is coupled to the ground terminal 70 by a coupling hole 82a formed in the body.

Meanwhile, another embodiment of the present invention is shown in FIG. 3, which means that the grounding means is coupled to a distal end of one side of the through hole 21 of the cover 20 in which the case 10 is a conductive portion. The connecting piece 80 'having the hole 81' is formed to extend a predetermined length, and when the cover 20 is assembled to the case 10, the coupling hole 81 'of the connecting piece 80' is connected to the ground terminal. It is connected to 70 by being connected.

The present invention as in the above embodiment, since the conductive portion of the electric wire case, the metal cover is connected to the ground terminal by the grounding means is to prevent the electric shock accident by the leakage current through this.
