Detailed Description
As shown in fig. 1, the electronic tag with a magnetic attraction power supply provided in this embodiment includes a tag body 1 and a power supply 2. The tag body 1 is exposed with two conductive contacts 12 electrically connected to the processing module 11 on the tag body. The power supply 2 is arranged outside the tag body 1, positive and negative poles of the power supply 2 are led out to form a positive wiring terminal 21 and a negative wiring terminal 22, and the positive wiring terminal 21 and the negative wiring terminal 22 are respectively connected with the two conductive contacts 12 on the tag body 1 in a magnetic attraction mode. In the present embodiment, the processing module 11 includes a temperature sensor for detecting temperature. Therefore, the electronic tag provided in this embodiment is a wireless temperature detection electronic tag. However, the present invention is not limited in any way thereto. In other embodiments, the magnetically attractive connection between the power source 2 and the tag body 1 is equally applicable to other types of electronic tags.
The electronic tag with the magnetic attraction type power supply provided in this embodiment realizes the power supply 2 to the processing module 11 located in the tag body 1 through the magnetic attraction type connection between the two conductive contacts 12 and the positive wiring terminal 21 and the negative wiring terminal 22. Compared with the traditional power supply mode of welding connection, the power supply mode of magnetic connection greatly simplifies the wiring of a power supply; further, as no welding is needed, the connection between the power supply 2 and the tag body 1 does not affect the substrate and the metal antenna on the tag body, and the problems of poor contact and the like caused by the welding factors such as cold welding and the like are avoided, the manufacturing process of the active electronic tag is greatly simplified, and the formed electronic tag is simpler in structure.
In addition, the magnetic type connection is a nondestructive detachable connection, and the electronic tag with the magnetic type power supply provided by the embodiment of the connection mode can be used as an active tag (at the moment, the power supply and the tag body are magnetically connected), can also be used as a passive tag (at the moment, the power supply and the tag body are separated), and has good universality. Further, due to the detachable connection mode, when any one of the power supply 2 and the tag body 1 is damaged, fails or the service life of the tag body is up, the tag can be replaced, and the other one of the tag can continue to work.
In this embodiment, the power source 2 is a portable battery packaged by an insulating material, and the packaged external shape may be any one of rectangle, circle, semicircle, arc or ellipse. In order to save materials and to consider the ease of processing, it is preferable that the package shape of the power supply be rectangular or circular. In this embodiment, the power source 2 is a button cell. However, the present invention is not limited in any way thereto. In other embodiments, the power source 2 may be a paper battery. In this embodiment, the insulating material used for packaging the power supply 2 is PVC insulating material. However, the present invention is not limited in any way thereto. In other embodiments, the insulating material may be any of high molecular polymers such as PA, PVC, PE, PP, PU.
In the present embodiment, as shown in fig. 2, the positive and negative electrodes of the power supply 2 are led out to the surface of the insulating layer 23 thereof through a metal conductive material to form a positive connection terminal 21 and a negative connection terminal 22. However, the present invention does not limit the lead-out material of the positive and negative electrodes of the power supply 2 in any way. In other embodiments, other conductive materials, such as graphite or conductive paste, may be used to draw the positive and negative electrodes of the power supply 2. The metallic conductive material may be any of gold, silver, copper, aluminum, solder, or a conductive alloy.
In the present embodiment, the specific shape of the two conductive contacts 12 is a conductive block or a conductive film formed on the surface of the tag body in a planar shape. The end of the positive terminal 21 and the end of the negative terminal 22 on the electronic surface of the button have contact surfaces magnetically attracted to the conductive contacts, respectively. The surface-to-surface contact enables a sufficient magnetic connection between the two conductive contacts 12 and the positive and negative terminals 21, 22 so that an electrical connection between the two can be achieved well. In the present embodiment, the conductive contact 12 is a magnetic conductive block or a magnetic conductive film made of a magnetic conductive material formed on the surface of the tag body 1. Specifically, the two conductive contacts are made of alnico magnets. However, the present invention is not limited in any way thereto. In other embodiments, the magnetically conductive material may be a steel magnet.
Since the magnet can be magnetically attracted to the metal or another magnet, in this embodiment, the positive connection terminal 21 and the negative connection terminal 22 each include a contact portion 211 and a conductive portion 212, the contact portion 211 has a contact surface magnetically attracted to the conductive contact, so as to implement magnetic attraction connection, and the conductive portion 212 passes through the contact portion 211 to be connected to the positive electrode or the negative electrode of the power supply 2, and when the contact surface on the contact portion 211 contacts the conductive contact 12, the conductive portion 212 also contacts the conductive contact 12 to implement electrical connection between the conductive contact 12 and the power supply 2, so that the power supply 2 can supply power to the processing module 11. In the present embodiment, the contact portions provided on the positive terminal 21 and the negative terminal 22 are made of a magnetic material, and the contact surfaces thereof are magnetic contact surfaces magnetically connected with the conductive contacts. In this embodiment, the magnetic material is alnico magnet. However, the present invention is not limited in any way thereto. In other embodiments, the magnetic material may be any of a steel magnet, a samarium cobalt magnet, a ferrite magnet, and a neodymium iron boron magnet.
The independent arrangement of the contact portion 211 and the conductive portion 212 allows for a better choice of materials for forming the conductive portion 212, thereby allowing for a better electrical connection, such as an optimized design for reducing the resistance on the conductive portion 212. However, the specific structures of the positive terminal 21 and the negative terminal 22 are not limited in the present invention. After the conductive contacts 12 are magnetically attractive, in other embodiments, the positive terminal 21 and the negative terminal 22 may be integrated and made of a non-magnetic but attractive metallic conductive material to the conductive contacts 12 or integrated and made of a magnetic metallic conductive material, which may be an alnico magnet or a steel magnet. Compared with the structure of the positive wiring terminal 21 and the negative wiring terminal 22 provided by the embodiment, the integrated positive wiring terminal 21 and the negative wiring terminal 22 can better realize the contact with the conductive contact, and the phenomenon of poor contact can be greatly reduced, but the integrated structure needs to consider the design of the contact area and the conductive performance.
Also, in other embodiments, two conductive contacts 12 may be provided as conductive blocks or conductive films made of nonmagnetic metal materials, and the positive terminal 21 and the negative terminal 22 may be the structures provided in the present embodiment or integrated structures made of magnetic metal conductive materials. That is, the distribution of the magnetic attraction property of the two is not limited on the premise that the magnetic attraction connection of the two is satisfied.
In the conventional electronic tag, the metal antenna is formed by a loop around the tag body 1, a certain gap is provided between the loops, and when the gap between the loops is smaller than or equal to the diameter of the power supply 2, the tag body 1 further comprises a connection portion 14 disposed outside the antenna portion 13, and two conductive contacts 12 are formed on the antenna portion 13, so as to avoid the influence on the metal antenna.
Example two
This embodiment is substantially the same as the first embodiment and its variations, except that: the structure of the conductive contacts 12 differs and the position of the conductive contacts 12 on the tag body 1 differs.
Specifically, as shown in fig. 3, in the present embodiment, the conductive contact 12 is at least one through hole formed on the tag body, at least one protruding portion 221 matching with the through hole is respectively provided on the positive connection terminal 21 and the negative connection terminal 22 of the power supply, and the magnetic connection between the protruding portion 221 and the through hole is used to realize the electrical connection between the power supply 2 and the processing module 11. However, the present invention is not limited in any way thereto. In other embodiments, the conductive contact 12 may be at least one recess formed on the tag body. In the present embodiment, the conductive contact 12 is composed of a plurality of through holes formed on the tag body 1, and the corresponding positive terminal 21 and negative terminal 22 also have a plurality of protrusions matching the number of through holes.
In the present embodiment, a magnetic conductive layer is provided on the inner surface of each through hole, and the conductive contact 12 is magnetically attracted to the convex portion 221 on the positive terminal 21 and the negative terminal 22 of the power supply through the magnetic conductive layer. Preferably, the magnetic conductive layer is an alnico magnet layer. However, the present invention is not limited in any way thereto. In other embodiments, the magnetically conductive layer may be a steel magnet layer.
In the present embodiment, the convex portions 221 on the positive and negative terminals 21 and 22 are made of a metal material such as any one of gold, silver, copper, aluminum, solder, or conductive alloy that attracts the magnetic conductive layer. However, the present invention is not limited in any way thereto. In other embodiments, the protrusions 221 on the positive terminal 21 and the negative terminal 22 may be made of a magnetically conductive material, such as an alnico magnet layer or a steel magnet layer. Likewise, in other embodiments, the protrusions 221 on the positive and negative terminals 21, 22 may be provided with magnetic properties, while the conductive contacts 12 are made of a non-magnetic metallic conductive material.
In the present embodiment, the diameter of the boss 221 is set to be greater than or equal to 1 mm and less than or equal to 10 mm, and preferably, the diameter of the boss 221 is set to be 3.0 mm or 3.5 mm. The height of the boss 221 is 0.5 mm or more and 10 mm or less. Preferably, the height of the set boss 221 is 2.0 mm or 2.5 mm. However, the present invention is not limited in any way thereto. The diameter and height of the boss 221 may be sufficient to provide proper contact with the conductive contact 12.
In this embodiment, the gap between turns of the metal antenna in the tag body 1 is large and larger than the diameter of the power supply 2. Thus, as shown in fig. 2, two conductive contacts 12 may be provided between turns of the metal antenna. The present embodiment provides a tag body having a structure with a smaller volume than the tag body of the first embodiment.
In summary, according to the electronic tag with the magnetic attraction type power supply provided by the invention, the tag body is connected with the power supply by arranging the two conductive contacts for supplying power to the processing module on the tag body and arranging the positive wiring terminal and the negative wiring terminal which are connected with the positive electrode and the negative electrode of the power supply on the power supply to be respectively connected with the two conductive contacts in a magnetic attraction type manner. Compared with the traditional welding type connection mode, the magnetic type connection mode provided by the invention effectively avoids the influence of welding on the metal antenna, greatly simplifies wiring between the tag body and the power supply, and is simpler and more convenient to connect. And the magnetic connection has good connection stability, and the problems caused by the cold joint in the traditional welding connection can be avoided. Furthermore, the magnetic connection between the tag body and the power supply realizes the detachable connection between the tag body and the power supply, so that the electronic tag provided by the invention can be used as an active tag or a passive tag, and the universality and replaceability of the tag are greatly improved.
Although the invention has been described with reference to the preferred embodiments, it should be understood that the invention is not limited thereto, but rather may be modified and varied by those skilled in the art without departing from the spirit and scope of the invention.
