Abstract

The utility model discloses a miniature RFID glass tube electronic tag, which comprises an RFID chip with a built-in capacitor, and a coil electrically connected with the RFID chip, wherein the RFID chip is enclosed in a toughened glass tube, and the coil is wound on a magnetic core to form a tag antenna. Because the RFID chip is provided with the built-in capacitor without additional arrangement, the volume is smaller, the tag antenna is formed by the coil wound on the magnetic core, and the sensitivity of the electronic tag is greatly improved so as to make the identification distance and the reliability of the RFID miniature electronic tag greatly enhanced under the same condition. The practicability of the electronic tag is wider, and the electronic tag belongs to a real miniature electronic tag.

Description

A kind of Micro RF ID glass tube electronic tag

Technical field

The utility model relates to a kind of electronic tag, and particularly a kind of dress is enclosed in the Lontactless electronic tag in the glass tube.

Background technology

Along with popularizing of RFID contactless identification technology comprehensively, the kind of RFID electronic tag on the market more and more trends towards the multiband development, and its appearance forrns is also more and more diversified.Because constantly continuing of RFID technology is progressive, the making development of RFID electronic tag is also ripe day by day, and has obtained using widely in all trades and professions.Yet, because traditional RFID electronic tag card class, be subjected to the limitation of self face shaping and physical size, can not be applicable to all use occasions, as the more special occasion of commodity counterfeit prevention, pet sign, environment for use etc., must use volume less relatively RFID electronic tag, especially Micro RF ID electronic tag.

China Patent No. is ZL200620062913.7; publication number is that the utility model patent of 2938228 " a kind of miniature electric label " discloses a kind of electronic tag; the technical scheme that this electronic tag adopts is: integrated circuit die is stacked on the patch capacitor; the two ends of patch capacitor are connected with the pin of integrated circuit die by connecting line; on patch capacitor, be bonded with insulation protection glue; insulation protection glue is wrapped in whole integrated circuit die in it; circuit die is wrapped in it; make patch capacitor and integrated circuit die constitute an integral body; two terminations of aerial coil are connected to the two ends of patch capacitor; this electronic tag is encapsulated in an internal diameter less than in two millimeters the glass tube with whole members; it is bigger than normal to have overcome plain edition RFID electronic tag volume; can't be in some defectives that the tighter place of its volume requirement is used; as a branch in the RFID family; this miniature electronic label; with the contactless smart card product of other kind large-scale popularization in the industry-by-industry field; extraordinary expansion and complementary effect have been played; but owing to there is a patch capacitor in this electronic tag; volume is not enough little; particularly this electronic tag does not use the high miniature bar magnet of magnetoconductivity; its induction sensitivity is not high, and decipherment distance is very limited.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides the Micro RF ID glass tube that a kind of volume is little, highly sensitive, decipherment distance is far away electronic tag.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of Micro RF ID glass tube electronic tag comprises that dress is enclosed in the RFID chip of the built-in capacitance in the tempered glass pipe, and with the coil that the RFID chip is electrically connected, described coil winding forms label antenna on a magnetic core.

As further improvement of the utility model, described RFID chip and coil adopt the technology welding of straight nation; Be filled with fluid sealant in the described tempered glass pipe.

The beneficial effects of the utility model are: the RFID built-in chip type electric capacity that the utility model adopts, need not to add, therefore, volume is littler, label antenna is formed by a coil that is wound on the magnetic core, has improved the induction sensitivity of electronic tag greatly, makes the decipherment distance and the reliability of the RFID miniature electronic label under square one strengthen greatly, practicality is also more extensive, belongs to real miniature electronic label.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Embodiment

With reference to Fig. 1, a kind of Micro RF ID glass tube electronic tag, comprise that dress is enclosed in the RFID chip 3 of the built-in capacitance in the tempered glass pipe 5, the coil 2 that the high strength fine copper enameled wire that is electrically connected with RFID chip 3 is made, because the RFID built-in chip type electric capacity that adopts need not to add, therefore, volume is littler, belongs to real miniature electronic label; Described coil 2 is wound on the high permeability magnetic core 1 and forms label antenna, has improved the induction sensitivity of electronic tag greatly, makes the decipherment distance and the reliability of the RFID miniature electronic label under square one strengthen greatly, and practicality is also more extensive.

RFID chip 3 of the present utility model and coil 2 adopt the technology welding of straight nation, connect reliably, and quality is secure, and framework is more reasonable; Be filled with the professional electronic seal glue 4 of environmental protection in the described tempered glass pipe 5, sealing glue 4 can seal up magnetic core 1, coil 2 and the coil 2 straight nation place with RFID chip 3 in the mode of seamless filling, structure is more solid, and the other end sintering shutoff with tempered glass pipe 5 behind the encapsulating gets final product.

More than be preferable embodiment of the present utility model, can not limit protection domain of the present utility model, so long as modification and the variation done according to protection domain of the present utility model, still belong within the scope that the invention contains.
