Description

Computer case for a working site capable of blocking an accident current and microwaves}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer case, and more particularly to a lightning current generated during a thunder or lightning strike, a spark current generated during electric welding, or an electromagnetic wave generated from a computer main body or a display device. The present invention relates to a computer case for a workplace.

Personal computers are generally divided into desktop and portable computers. The desktop computer is mainly used in a fixed place, such as a general office or home, and the portable computer is configured to be portable so that it can be used while moving. In the computer case, various hardware devices, such as a main circuit board (main board), an HDD, an FDD, a CD-ROM drive, a storage device such as a DVD, and a power supply, are fixed and housed. A computer case of a typical desktop computer is composed of a frame for fixing a hardware device and an outer case which is coupled to the frame and surrounds the inner frame to form an exterior. The frame constitutes the bottom and back of the body and the internal skeleton. Usually, it consists of several parts cut into steel plates and bent into the required shape. These parts are assembled by welding or screwing together. Various hardware is fixed here, so it is designed to have sufficient structural strength. The outer case constitutes the front, flat and left and right sides of the main body. The parts constituting the plane and the left and right sides are mainly manufactured as a single part by cutting and bending the steel sheet. The part covering the front is made of plastic injection molding. These case parts are fixed to the frame to form a case, and various hardware devices are stored therein. In particular, the portable computer includes a display unit in which a liquid crystal display panel is installed, and an operation unit in which various hardware such as a keyboard and a main circuit board (main board), a storage device such as an HDD, an FDD, a CD-ROM drive, a DVD, and a power supply are installed. The display unit and the operation unit are each provided with an outer case, and one side of the outer case is hinged to each other so that the display unit is installed to be opened and closed with respect to the operation unit. The outer case is generally composed of a lightweight synthetic resin material or metal material.

There are also numerous metal subsidiary facilities in the workshop. Thus, during a thunderstorm or lightning strike, lightning currents flow through these subsidiary facilities into the workplace and make electrical contact with the outer case of the computer. As described above, since the outer case of the computer is made of a metal material, a lightning current flows down and a momentary impulse current is applied to the circuit board (main board) to cause a fatal damage to the circuit board (main board). There was often a case.

In addition, the computer is exposed to the electromagnetic waves emitted from it for a long time. Commonly speaking electromagnetic waves are those belonging to the types of non-electron radiation (microwaves, radio waves, visible light), and also include ultrasonic waves and low electromagnetic fields. Electromagnetic waves travel at a speed of 300,000 km per second, like the speed of light. Since electromagnetic waves are a kind of wavelength, they are expressed in frequency. Frequency represents the number of cycles per second and Hz is used as a unit. Electromagnetic waves are waves that cause changes in the electric and magnetic fields formed around the current. At home, for example, 60 Hz alternating current produces 60 electron waves per second, with the 60th electrode changed over a second. The shorter the wavelength (the more frequencies per second), the higher the energy. As a source of electromagnetic waves, electromagnetic waves are generated in all appliances that use electricity. In other words, electromagnetic waves are generated in all home appliances including TVs. Among the household appliances, a relatively large amount of electromagnetic waves is generated from microwave ovens using high energy microwaves of 2,450 MHz, mobile phones or car phones using microwaves of 800 to 900 MHz, And computers.

The effect of electromagnetic waves on the human body is the effect of generating heat, stimulating effects on nerves and muscles, and direct action on the potential difference of biological membranes, which can cause various physiological changes. Action.

In addition, the effects of electromagnetic waves on the human body include: disturbance of the eyes, which can cause cataracts, effects of hormone secretion on the adrenal cortex and thyroid gland by electromagnetic waves, and on the endocrine system, which also alters glucose metabolism. Effects on the hematopoietic system that causes leukemia due to lymphocytes and leukocyte increase, the effects of electromagnetic wave malformation or premature miscarriage, and electromagnetic wave on the reproductive system Impact.

In other words, if the computer is not grounded, the computer will move to a person whose residual electrical energy is 0 volts (V) and cause various side effects on the body. It affects your health, and if the frequency is low, the current induced in the body may stimulate nerves.

The function of the nervous system is affected by the electrical and chemical changes in the body, so very strong electromagnetic waves can affect the human body by causing stress, heart disease, and chemical changes in the blood. In particular, since the keyboard of the portable computer is placed on the main body of the portable computer, there is a problem that the user is exposed to much more electromagnetic waves than the desktop computer.

Accordingly, the present invention has been invented to solve the above problems, and a plurality of electrical wires are introduced into the hollows of the aluminum armature and the plastic semi-circular grooves, which are expected of the computer storage box, and through these electrical wires, lightning currents, spark currents, or electromagnetic waves.
