Description

Anti-metal electronic tag

Technical field

The utility model relates to a kind of anti-metal electronic tag.

Background technology

Among the disclosed Chinese patent bulletin CN201196852Y a kind of " passive electronic label " disclosed on February 18th, 2009, it is connected custom-designed butterfly directional antenna Intelligent Passive microchip, be made into the label of the similar size of shape such as same bookmark, thin and thick, stick on the surface of testee, be used to accept the signal that intelligent reader is issued, and the information of its storage inside is sent or writes; Its appearance adopts the papery encapsulation, is carved with the anti-line that tears, and pastes the back and will cause antenna to be connected disconnection with chip in case tear it down, and label lost efficacy; In the chip of its inside, all solidify unique identification code, can not artificially change, guaranteed the uniqueness of label.The shortcoming of existing this electronic tag is can not be attached to metal body surface to use, and uses because the electromagnetic wave that metallic object sends reader has reflection, thereby makes electronic tag be difficult to effectively receive electromagnetic wave or outside emitting electrons signal.

Summary of the invention

The purpose of this utility model is the problem that can not stick on the metal material surface use that exists in the existing electronic tag in order to solve, and a kind of anti-metal electronic tag that can stick on metal body surface simple in structure, easy to use is provided.

The purpose of this utility model is achieved in that a kind of anti-metal electronic tag, constitute by chip and the plastic sheeting that is compounded with antenna, it is characterized in that described antenna material is the aluminium film and is made of emitter, connecting line and earthing pole, connecting line is connected between emitter and the earthing pole, described chip also is connected between emitter and the earthing pole, the inboard of described plastic sheeting and the plastic base of rectangular parallelepiped are pasted together, and wherein said emitter is positioned at the plastic base front and earthing pole is positioned at the back side of plastic base.Positive outside, the back side of plastic base sticks on metal body surface during use.

Described chip is in the joint face that connects between the plastic base front and the back side.

Described connecting line is in the joint face that connects between the plastic base front and the back side.

Described antenna is positioned at the outside of plastic sheeting.

The both sides edge of the front of described plastic base and joint face is provided with the muscle that protrudes the plastic base surface.

Owing to adopted technical scheme described in the utility model, leave certain distance between the emitter of the antenna of electronic tag and the metallic object, reduced the interference of metallic object to emitter, guarantee that electronic tag can effectively receive electromagnetic wave, improved the reliability of electronic tag, both can use and also can use in liquid at metal body surface.

Among the figure 1, plastic base, 10, the front, 11,12, muscle, 13, joint face, 2, plastic sheeting, 3, emitter, 30, earthing pole, 4, chip, 5, connecting line.

Embodiment:

Seeing shown in Figure 1ly, is the schematic perspective view of a specific embodiment of anti-metal electronic tag described in the utility model.

See Fig. 2, it is the stereo appearance figure of plastic base 1 among Fig. 1 embodiment, it is the rectangular parallelepiped of 34 millimeters X44 millimeters of one 6 millimeters X, material is poly terephthalic acid ethylene glycol (being PET), one side up is positive 10, the one side of not seeing among down the figure with positive 10 symmetries is the back side, connect positive 10 and the back side be joint face 13, be provided with the

muscle

11 and 12 on protrusion plastic base surface in the both sides edge of the front 10 of plastic base and joint face 13.

See Fig. 3, it is the compound plane outspread drawing of the plastic sheeting behind the antenna among Fig. 1 embodiment, from this figure as seen, four limits of plastic sheeting 2 constitute a rectangle that is about 29 millimeters X89 millimeters, in its surface recombination the antenna that constitutes by the aluminium film, the rectangle of its 27 millimeters X36 millimeters in middle and upper part is emitters 3, the rectangle of the 27 millimeters X41 millimeters in bottom is earthing poles 30, between emitter 3 and earthing pole 30, be connected with six connecting lines 5, four connecting lines in the middle of wherein outermost two connecting lines slightly are coarser than, and chip 4 usefulness lines are connected between emitter 3 and the earthing pole 30, and the material of all six connecting lines 5 and the line that is connected chip all is the aluminium film that is compounded on the plastic base; Spacing between emitter 3 and the earthing pole 30 is slightly larger than the width of joint face among Fig. 2, and the spacing between two

muscle

11 and 12 is suitable among the width of plastic sheeting 3 and Fig. 2.

In conjunction with Fig. 2 and Fig. 3, emitter among Fig. 33 is sticked on the front 10 of plastic base among Fig. 2, the back side that earthing pole 30 sticks on plastic base among Fig. 2, make spacing between emitter and the earthing pole roughly be arranged in the joint face 13 of Fig. 2, can obtain anti-metal electronic tag described in the utility model shown in Figure 1.
