Abstract

The utility model discloses a device for eliminating electrostatic charge from human body. The utility model is mainly composed of a resistor (1), a current indicator (2), a spring (4) and a contact head (3) or a ground wire which are connected in series. When a user touching the resistor (1) by a finger, static electricity on the human body is leaked to ground through the resistor (1), the current indicator (2), the spring (4) and the contact head (3) or the ground wire, so the static electricity of the human body is eliminated. The current is displayed by the current indicator (2) in leakage process; the current in leakage process is very small because of the limiting function of the resistor (1) to the current, so the finger has no feeling.

Description

Static electricity on human body's remover

The utility model relates to a kind of static electricity on human body's remover.

Under drying regime, the friction of human body and the locker room of wearing can make the human body static electrification, and its electrostatic potential can be up to more than the 10kv, though electric weight is little, when touching electrical type accurate device such as computer chip when human body, still can produce destruction; If human body touches the conductor with certain electric capacity, discharging current can be greater than 100 μ A, and the skin of people and conductor contact position just has sense of discomfort or picotement, is promptly shocked by electricity.This electric shock not only makes person discomfort, also makes people nervous.In order to remove the static electricity on human body, on workman's wrist of working on the precision electronic device production line usually with one the conduction becket, and with lead with becket ground connection, as long as human body one produces static, this static will leak away through earth lead from the becket on the wrist.Because the most of people in the daily life are often movable, so with the human body grounding inconvenience.

The purpose of this utility model provides a kind of static electricity on human body's remover, and people can utilize it to remove static on the human body safely at any time.

For achieving the above object, the utility model static electricity on human body remover is made up of resistance, current indicator, spring, contact, insulation crust, and resistance exposes, and resistance is 6 * 10 ⁶Ω to 8 * 10 ¹⁰Between the Ω, pass through to guarantee safe current; Current indicator can adopt neon tube or light-emitting diode, to show the static reset procedure; Contact is manufactured with electric conductor, is used for contacting with earth electrode; Spring also adopts electric conductor to manufacture, and can guarantee to contact between resistance, current indicator and contact good; Insulation crust manufactures or opens transparent window with transparent plastic, to observe the procedure for displaying of current indicator.During use, with contact ground connection, use finger touch resistance, if human body has static, then electrostatic induced current leak into the ground connection place through resistance, current indicator, spring, contact, thereby the static on the removing human body, because of the restriction of resistance to electric current, leakage current is little, the human body insentience, in reset procedure, current indicator shows.

The also available lead of contact in above-mentioned static electricity on human body's remover replaces, an end ground connection of this lead, and the other end contacts with spring, and insulation crust is convenient to be fixed on desktop or the wall.During use, touch resistance with hand and get final product.

Resistance in above-mentioned static electricity on human body's remover can be divided into the different plurality of sections of resistance, as to be divided into resistance be 10 ¹⁰Ω, 10 ⁸Ω, 8 * 10 ⁶3 sections of Ω etc.During use, can be earlier with big one section of finger touch resistance, in order to avoid resistance is little, leakage current is big, finger is uncomfortable.

Because the utility model static electricity on human body remover is simple in structure, can carry or be installed in the place that people such as room, workshop, office are everlasting, and is easy to use; Because of the metering function of resistance, the human body insentience is safe and reliable in the use.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the circuit theory diagrams of first execution mode of the utility model static electricity on human body remover.

Fig. 2 is the cutaway view of execution mode static electricity on human body remover shown in Figure 1.

Fig. 3 is the circuit theory diagrams of second execution mode of the utility model static electricity on human body remover.

Fig. 4 is the vertical view of execution mode static electricity on human body remover shown in Figure 3.

Fig. 5 is the cutaway view of static electricity on human body's remover shown in Figure 3 along I-I.

In circuit theory diagrams shown in Figure 1, resistance 1, current indicator 2 and contact 3 are in series, when contact 3 ground connection, with finger touch resistance 1, static on the human body leak into contact 3 ground connection place through resistance 1, current indicator 2, contact 3, thereby removes the static on the human body.In leakage process, current indicator 2 shows that because of the restriction of 1 pair of electric current of resistance, electric current is very little during leakage, the finger insentience.

Fig. 2 is the longitudinal section of static electricity on human body's remover of forming by the foregoing circuit principle design.Contact 3 is fixed in an end of insulation crust 5; Whether insulation crust 5 can be made with transparent plastic, or opens a transparent window, show so that observe current indicator 2; Current indicator 1 adopts neon tube, also can adopt light-emitting diode; At dress resistance 1 place, insulation crust 5 has an opening, can be with finger touch to resistance 1 from opening part; Bonnet 6 tightens together with insulation crust 5; It is reliable that the pressure of spring 4 can make contact 3, current indicator 2,1 of resistance be electrically connected, and the resistance of resistance 1 can be different because of its position.

Fig. 3 is the circuit theory diagrams of second execution mode of the utility model static electricity on human body remover, its earth lead 7 has replaced the contact 3 in first execution mode, during with finger touch resistance 1, static on the human body leaks away through resistance 1, current indicator 2, earth lead 7, thereby removes the static on the human body.In leakage process, current indicator 2 shows that because of the restriction of 1 pair of electric current of resistance, electric current is very little during leakage, the finger insentience.

Fig. 4, Fig. 5 is static electricity on human body's remover of the another kind of concrete structure that designs by circuit theory diagrams shown in Figure 3, resistance 1 is housed on the insulator foot 8, current indicator 2 and earth lead 7, the pressure of spring 4 can make resistance 1,7 of current indicator 2 and earth leads are electrically connected reliable, one circular hole 10 is arranged on the insulator foot 8, in order to be fixed on the wall static electricity on human body's remover or other place, transparent window is made or had to insulating top cover 9 usefulness transparent plastics, so that whether observe current indicator 2 shows, also has an opening on it, resistance 1 is exposed out, so that touch with hand, the resistance of resistance 1 can be different because of its position.
