Abstract

(57) [Abstract] [Purpose] The present invention provides a structure of a data carrier capable of preventing disconnection of a coil wire due to vibration when the data carrier is used. [Structure] As shown in FIG. 1, an outer casing 9 is provided with a housing groove 10 for housing a communication coil bobbin 6, and the housing groove 1
After mounting the communication coil bobbin 6 electronic module 3 on a data carrier having a structure in which a protrusion 11 is provided in a part of 0, the outer case 9 is sealed by an ultrasonic welding method. At this time, the protrusion 11 of the housing groove 10 comes into contact with the communication coil bobbin 6 and melts by the vibration energy of the ultrasonic welding method, so that the communication coil bobbin 6 and the outer case 9 are integrally fixed. [Effect] It is possible to prevent disconnection of the coil wire near the connection point between the communication coil and the electronic module due to vibration during use, and FA, O
It becomes possible to introduce A, and the effect is widespread.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a data carrier having a communication coil.

[0002]

[Prior Art]

 Conventionally, a data carrier having a communication coil has an electronic module 3 in which an electronic component 2 is mounted on a circuit board 1 and a communication coil 4 in a space inside an outer case 5 formed of plastic resin as shown in FIG. After that, the electronic module 3 and the communication coil 4 are connected and the outer case 5 is sealed.

[0003]

[Problems to be solved by the device]

 However, the data carrier having the above structure is incompletely fixed because the communication coil bobbin 6 is fixed with an adhesive or the like, and the position of the communication coil bobbin is displaced due to vibration during use and the connection point with the electronic module. There was a problem that nearby coil wires were broken and their function was impaired.

The object of the present invention is to securely fix the communication coil bobbin, and to prevent disconnection of the coil wire near the connection point between the communication coil and the electronic module due to vibration during use. It provides the structure of the carrier.

[0005]

[Means for Solving the Problems]

 In order to achieve the above purpose, a groove for accommodating the communication coil bobbin is provided inside the outer case made of plastic resin, and part of the groove is affected by the vibration energy during the ultrasonic welding process, which is the outer case sealing process. The structure of the data carrier is provided with the protrusions that dissolve. With this structure, the protrusion in a part of the groove is melted during the sealing of the outer case and the communication coil bobbin or the communication coil is fixed to the outer case.

[0006]

[Action]

 By using the structure of these data carriers, it is possible to fix the communication coil and prevent disconnection of the coil wire near the connection point between the communication coil and the electronic module due to vibration etc. when using the data carrier. I made it.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the data carrier structure of the present invention has an outer case 9 having a groove for accommodating the communication coil bobbin 6 inside an outer case 9 formed of plastic resin, a coil wire 8 for communication, The communication coil 4, the communication coil bobbin 6, the circuit board 1, the electronic component 2, and the electronic module 3 are included. As shown in FIG. 1, the data carrier of the present invention is provided with a housing groove 10 for housing the communication coil bobbin 6 inside an outer case 9 formed of a plastic resin, and a protrusion 11 is provided in a part of the housing groove 10. After mounting the communication coil bobbin 6 having the communication coil 4 wound thereon and the electronic module 3 in which the electronic component 2 is mounted on the circuit board 1, the external case 9 having the provided structure is used for communication with the electronic module 3. The coil 4 is connected and the outer case 9 is sealed by an ultrasonic welding method.

At this time, the protrusion 11 of the housing groove 10 inside the outer case 9 is melted and fixed to the communication coil bobbin 6 by the vibration energy of the ultrasonic welding method, and the communication coil 4 and the electronic coil 4 due to the vibration etc. when the data carrier is used It has been possible to prevent disconnection of the coil wire 8 near the connection point with the module 3.

[0009]

[Effect of the device]

 As described above, according to the data carrier structure of the present invention, it is possible to prevent disconnection of the coil wire near the connection point between the communication coil and the electronic module due to vibration during use, etc. It is possible to introduce FA and OA into fields that are not good, etc., and their effects are widespread.
