Clasp for jewelry and bracelet and necklace using same

Abstract

The invention relates to a clasp for jewelry and a bracelet and a necklace using the same. The clasp comprises a shell and a contact used together with the shell, wherein the shell is formed by connecting a front cover and a rear cover; an elastic O-shaped ring, a chip and a battery are arranged in the shell in turn; a cathode surface of the battery is electrically contacted with a cathode of thechip; an insulating bush is wrapped outside the battery; the rear cover is provided with a hole for exposing an anode surface of the battery; the contact comprises a magnetic column, a conductive sheet and a magnetic column bush, wherein the first end of the magnetic column can be inserted into the hole on the rear cover, the conductive sheet is contacted with the second end of the magnetic column, and the magnetic column bush is wrapped outside the magnetic column and exposes the first end of the magnetic column; and the anode of the chip is electrically connected with the conductive sheet through a lead. An adsorption force between the magnetic column and the metal fastener battery is skillfully used as a switch for turning on and off the battery, so the structure is simple and the use is convenient; and the luminous bracelet and the luminous necklace adopting the clasp with the structure have attractive appearance and convenient use.

AI Technical Summary

Problems solved by technology

The light-emitting necklace with the above structure has a relatively complicated structure, and the power switch is arranged on the flashing light IC circuit, so it is not very convenient to operate and use

Also for example the announcement number is: CN 2053449 (patent No. is: ZL 89212540.3) Chinese patent "Electronic Luminous Earrings", this electronic luminous earrings comprising shape blocks is characterized in that batteries and luminous tubes are housed on the earrings, and the luminous tubes are covered with There are decorative lampshades in different colors and shapes. This kind of electronic light-emitting earrings does not have a switch to control the light-emitting tube, and the battery will run out quickly.
