Description

Contactless card

Technical field

The utility model relates to a kind of contactless card, refers to a kind ofly except that the effect that this contactless card is reached be easy to volume production to be made especially, also can make this contactless card be difficult in use making this contactless card have the contactless card of the preferable opering characteristic of electric apparatus because of bending causes damage.

Background technology

Usually; General existing electronic chip card 5 (like Fig. 1 and shown in Figure 2); It is made up of card body 51, conductive adhesive layer 52 and chip 53; The one side of this card body 51 is provided with disposal area 511, and the both sides of this disposal area 511 are respectively equipped with conductive part 512, and these card body 51 inside are buried the sensing coil 513 that is connected with conductive part 512 underground; This conductive adhesive layer 52 is located in the disposal area 511; This chip 53 is arranged in the disposal area 511 and is laminated on the conductive adhesive layer 52, and the one side of these chip 53 corresponding disposal areas 511 is provided with two contacts 531, makes this contact 53

1 can form conducting through conductive adhesive layer 52 and each conductive part 512; Thus, constitute electronic chip card 5.

But because this electronic chip card 5 during fabrication; Produce the card body 51 of burying sensing coil 513 underground earlier; Assemblies such as conductive part 512, conductive adhesive layer 52 and chip 53 are set afterwards more one by one, make that the making formality is comparatively loaded down with trivial details, and regular meeting expend more man-hour and operation when a large amount of the manufacturing; Make fraction defective improve, and influence the quality of electronic chip card 5;

In addition because this card body 51 is that the rigid plastic material is made; And sensing coil 513 forms for the material institute winding of copper; Therefore this card body 51 not only can produce fracture because of careless stubborn folding; And when card body 51 receives stubborn folding, also can influence its inner sensing coil 513 simultaneously, make this sensing coil 513 form short circuit because of being out of shape or overlapping each other; Moreover owing to the chip 53 of this electronic chip card 5 only is fixedly arranged in the disposal area 511 with conductive adhesive layer 52; Therefore after when this electronic chip card 5 is carrying, being squeezed or using a period of time; Regular meeting makes this chip 53 have loosening situation to take place; Cause the contact 531 of chip 53 to produce the situation of loose contacts with each conductive part 512, and the electrical specification when influence chip 53 uses.

Summary of the invention

Therefore, the fundamental purpose of the utility model is, is easy to the effect of volume production manufacturing except that this contactless card is reached, and also can make this contactless card be difficult in use making this contactless card have preferable electrical specification because of bending causes damage.

For achieving the above object, the utility model provides a kind of contactless card, comprises bottom; Be laminated in the protective seam on the bottom one side, the appropriate location of this protective seam is provided with perforation; Be laminated in the inductive layer on the protective seam one side, this inductive layer is provided with inductive coil, and this inductive coil is electrically connected with correspondence and is located at the chip in the perforation; And be laminated in the printed layers on the inductive layer one side, have the pattern district on this printed layers.

Embodiment

See also Fig. 3,4 and shown in Figure 5, be respectively the A-A diagrammatic cross-section of Fig. 4 of three-dimensional appearance synoptic diagram and the utility model of perspective exploded view, the utility model of the utility model.As shown in the figure: the utility model provides a kind of contactless card, and it is made up of bottom 1, protective seam 2, inductive layer 3 and printed layers 4 at least.

The above-mentioned bottom that provides 1 can be complied with the suitable size that is required to be.

This protective seam 2 is laminated on the one side of above-mentioned bottom 1, and the appropriate location of this protective seam 2 is provided with perforation 21.

This inductive layer 3 is laminated on the one side of above-mentioned protective seam 2, and is formed with inductive coil 31 with etching mode on this inductive layer 3, and this inductive coil 31 can be the material of tin, and this inductive coil 31 is electrically connected with correspondence and is located at the chip 32 in the perforation 21.

This printed layers 4 is laminated on the one side of above-mentioned inductive layer 3, and has pattern district 41 on this printed layers 4.So, constitute brand-new contactless card through above-mentioned structure.

See also Fig. 6 and shown in Figure 7, the range upon range of view when the decomposing state synoptic diagram when being respectively the utility model making and the utility model are made.It is as shown in the figure: when the utility model is being made; Desirable large-sized bottom 1a, protective seam 2a, inductive layer 3a and printed layers 4a, and on the precalculated position of this protective seam 2a, offer most perforation 21a, and on this inductive layer 3a, etch a plurality of inductive coil 31a; And each inductive coil 31a is electrically connected with a chip 32a respectively; And a plurality of patterns district 41a is set on this printed layers 4, and afterwards that bottom 1a, protective seam 2a, inductive layer 3a and printed layers 4a is in addition range upon range of, the 32a correspondence is located among the perforation 21a; Each pattern district 41 is then corresponding with inductive coil 31a; Treat with hot pressing mode bottom 1a, protective seam 2a, inductive layer 3a and printed layers 4a to be combined again after range upon range of, cut with required instrument according to the sideline of each pattern district 41a periphery more at last, and then produce a plurality of contactless cards as shown in Figure 2; So, can reach the effect that is easy to the volume production manufacturing;

And because this bottom 1a, protective seam 2a, inductive layer 3a and printed layers 4a are respectively flexual material; Therefore be difficult for causing the damage of outward appearance or inductive coil 31a in use because of bending when this contactless card; Make this contactless card have preferable electrical specification, and do not have the situation generation of loose contact.

In sum; The contactless card of the utility model can effectively improve existing various shortcoming, is easy to the effect of volume production manufacturing except that this contactless card is reached, and also can make this contactless card be difficult in use causing damage because of bending; Make this contactless card have preferable electrical specification; And then making the utility model can more progressive, more practical, more meet user's needs, the true important document that has met utility application hence proposes patented claim in accordance with the law.

Only the above person is merely the preferred embodiment of the utility model, when not limiting the scope that the utility model is implemented with this; So all simple equivalent of being done according to the utility model claim scope and utility model description change and modify, all should still belong in the scope that the utility model patent contains.
