Copper foil connecting structure for electronic scales

Abstract

The invention discloses a copper foil connecting structure for electronic scales, which is characterized in that the copper foil connecting structure comprises ITO glass, a copper foil and a connecting assembly; the copper foil is electrically connected with a PCBA bonding wire; and the connecting assembly is used for attaching the copper foil to the ITO glass and keeping the copper foil in an attached state. The copper foil connecting structure is simple, and adopts a copper foil conductive technology. The copper foil is attached to an ITO film of the ITO glass and is electrically connected with the PCBA bonding wire. A current signal is led into a human body through the ITO film through the contact between the ITO film and the copper foil, and an induced voltage signal is obtained through the ITO film and the impedance of the human body is measured. The copper foil is sheet-shaped, so that the contact area of the copper foil and the ITO film is increased, the contact impedance is reduced, the human body impedance measured by a product is more accurate, the size of a decorative cover is reduced, and the production cost is reduced. The copper foil conductive technology is employedto make the assembling process of a product convenient and easy.

Description

technical field [0001] The invention relates to a copper foil connection structure for an electronic scale. Background technique [0002] The fat scale adopts the human body bio-resistance analysis technology. Its principle is to simply divide the body into conductive body fluids, muscles, etc., and fat tissue with poor conductivity. Then the measured biological resistance is larger, and vice versa. Because the fat scale can quickly and accurately analyze and calculate the body fat rate, it gradually replaces the traditional ordinary scale based on weight and height estimation. [0003] Existing human body electronic fat scales are generally made of ITO conductive glass. In order to form an electrical connection between the ITO film on the upper surface of the ITO conductive glass and the PCBA, the current ITO glass and PCBA are usually connected by metal connecting pieces and wires, and then connected through a decorative cover. The metal connecting piece is used to cover...

Problems solved by technology

[0003] Existing human body electronic fat scales are generally made of ITO conductive glass. In order to form an electrical connection between the ITO film on the upper surface of the ITO conductive glass and the PCBA, the current ITO glass and PCBA are usually connected by metal connecting pieces and wires, and then connected through a decorative cover. The metal connecting piece is used to cover; in order to reduce the contact resistance and better conductivity, the volume of the metal connecting piece is often increased, so that the contact area between the metal connecting piece and the ITO glass increases, and the metal connecting piece and the wire connection are added. The required space leads to a corresponding increase in the concealed decorative cover, which increases the volume of the decorative cover and increases its production cost. At the same time, the user will feel uncomfortable when standing on it with bare feet, and the user experience is very high. Difference
