According to the utility model, the helical antenna is additionally arranged so that a non-connected structure is formed between the chip and the communication antenna, the part processing precision and connection stability requirements are greatly reduced, the electronic label is more convenient to process, and the production efficiency is enhanced; and the metal reflecting plate is additionally arranged so that the loss of electromagnetic coupling between the communication antenna and the helical antenna is reduced, the communication distance of the electronic label is increased, and the application is facilitated.
Description
Technical field
The utility model relates to a kind of electronic tag, relates in particular to a kind of long apart from communication cut type Non-connecting electronic tag.
Background technology
Along with the deep development of wireless radio-frequency, the application of electronic tag (being RFID) is more and more extensive, and no matter industrial product orientation is followed the tracks of, and still the bus position in life shows in real time, all will use electronic tag.The machining precision of electronic tag, the stable connection degree between parts require also more and more higher, and the also quality of its practical application effect of direct relation of the communication distance of electronic tag.
Existing electronic tag, substantially all consists of substrate, chip and communication antenna, and chip and communication antenna are all located on substrate, and the communication terminal of chip is connected with communication antenna is corresponding.Different according to its power supply, electronic tag is divided into active electronic label and passive electronic label, and the former relies on the battery carrying that power supply is provided, and volume is large, power consumption is larger, and the latter relies on communication antenna to obtain power supply from electronic label read/write, and volume is little, power consumption is little.All there is following problem in above-mentioned traditional electronic tag: the communication terminal of chip is connected with communication antenna is corresponding, so the machining precision of parts and stable connection degree are had to higher requirement, not so easily cause the later stage cannot assembling parts or junction disconnect and cause electronic tag normally to use, will inevitably reduce production efficiency like this; Because the power of electronic tag is very little, and communication antenna is omnibearing when signal transmission, with the rightabout signal formation energy loss of electronic label read/write, makes its communication distance not enough, is difficult to meet increasing long apart from communicating requirement.These defects have all limited the deep application of electronic tag and further developing of radio-frequency technique.
Utility model content
The purpose of this utility model provides a kind of long apart from communication cut type Non-connecting electronic tag with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Long distance communication cut type Non-connecting electronic tag described in the utility model comprises substrate, chip, communication antenna, helical aerials and metallic reflection plate, described chip and described communication antenna are all located on the front of described substrate, described helical aerials be located on described chip and with the corresponding connection of communication terminal of described chip, position near described helical aerials on described communication antenna is provided with the otch that area is greater than the non-cut-out of described helical aerials, between described helical aerials and described communication antenna, pass through electromagnetic coupled wireless connections, described metallic reflection plate is installed on the back side of described substrate.
As preferably, described helical aerials is copper wire or the copper sheet being printed on described chip.
For ease of producing, described metallic reflection plate is pasted on the back side of described substrate by bonding agent.
Particularly, described metallic reflection plate is aluminium reflecting plate.Described bonding agent is epoxy resin.
The beneficial effects of the utility model are:
The utility model, by increasing helical aerials, makes to form between chip and communication antenna the structure of Non-connecting, greatly reduces machining precision and the requirement of stable connection degree of parts, makes electronic tag be convenient to processing, has improved production efficiency; By increasing metallic reflection plate, reduce the loss of communication antenna and helical aerials electromagnetic coupled, increased the communication distance of electronic tag, be convenient to application.
Accompanying drawing explanation
Fig. 1 is one of long vertical view apart from communication cut type Non-connecting electronic tag described in the utility model;
Fig. 2 is the A-A cutaway view Amplified image in Fig. 1;
Fig. 3 is two of the long vertical view apart from communication cut type Non-connecting electronic tag described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, long distance communication cut type Non-connecting electronic tag described in the utility model comprises substrate 2, chip 4, communication antenna 3, helical aerials 5 and metallic reflection plate 1, chip 4 and communication antenna 3 are all located on the front of substrate 2, helical aerials 5 be located on chip 4 and with the corresponding connection of communication terminal of chip 4, position near helical aerials 5 on communication antenna 3 is provided with the otch 6 that area is greater than the non-cut-out of helical aerials 5, between helical aerials 5 and communication antenna 3, pass through electromagnetic coupled wireless connections, metallic reflection plate 1 is by epoxy resin 7(bonding agent) be pasted on the back side of substrate 2.The otch 6 of above-mentioned non-cut-out refers to that the communication antenna 3 at otch 6 two ends is interconnective, and the shape of otch 6 is determined as required, is trapezoidal in this example.Between helical aerials 5 and communication antenna 3, no matter whether contact, can not change electromagnetic coupled wireless connections relation between the two, so low to the requirement on machining accuracy of parts.Communication antenna 3 is pasted on the front of substrate 2 by epoxy resin 7.
As depicted in figs. 1 and 2, helical aerials 3, for to be printed on the copper wire on chip 4, can be also the copper sheet of strip.Metallic reflection plate 1 is preferably aluminium reflecting plate.
The shape of chip 4 is determined as required, and as shown in Figure 1, chip 4 is circular, and as shown in Figure 3, chip 4 is square.
During use, whole electronic tag is mounted on to body surface, by electronic label read/write, electronic tag is completed to reading and writing of data, realize the accurate modernization tracing management of modern society's every profession and trade.
