Japanese Patent Laying-Open No. 2014-096612 (see paragraphs 0092 to 0095 and FIG. 12)

  As described above, the second substrate is disposed between the first substrate and the third substrate, and the outer peripheral portion of the first substrate and the outer peripheral portion of the third substrate are coupled by the spacer around the second substrate. Therefore, the projected area in the thickness direction of the first substrate and the third substrate needs to be larger than the projected area in the thickness direction of the second substrate. This hinders downsizing of the non-contact communication module.

  The present invention is to reduce the size of the non-contact communication module and the electronic device.

  In order to solve the above problems, the non-contact communication module of the present invention includes a first substrate, a second substrate, a first antenna, and a connection portion. The first substrate and the second substrate each have a first surface and a second surface opposite to the first surface. The second surface of the first substrate and the first surface of the second substrate face each other in the first direction. The first direction is the thickness direction of the first substrate and the second substrate. The projected area in the first direction of the second substrate is smaller than the projected area in the first direction of the first substrate. The second substrate is arranged so that the projected area of the second substrate is within the projected area of the first substrate. The first antenna is provided on the first surface of the first substrate and is configured to be able to communicate in a non-contact manner with the counterpart communication device. The connection part electrically connects the first substrate and the second substrate.

  Such a non-contact communication module can be miniaturized. This is because the projected area of the second substrate is smaller than the projected area of the first substrate, and the second substrate is arranged so that the projected area is within the projected area of the first substrate. By setting the area to a minimum size that can provide at least the first antenna, the projected areas of both the first substrate and the second substrate can be reduced. As a result, the contactless communication module can be reduced in size.

  The non-contact communication module may further include a housing. The housing can be configured to have a fixed portion and a housing portion. The fixing portion may be disposed outside the second substrate and fixed to the first substrate. The accommodating part accommodates at least the second substrate. In the case of the non-contact communication module having such an aspect, the fixing portion can be fixed to the first substrate without the fixing portion interfering with the second substrate.

  The housing may further include a guide portion that is disposed on one side in the first direction relative to the fixed portion in the housing portion and extends in the first direction. The second substrate can be configured to have a guide portion provided on the outer peripheral portion thereof. One of the guide part of the housing and the guide part of the second substrate is a guide convex part, and the other is a guide concave part into which the guide convex part is movably inserted along the first direction. It is possible. In the case of such a non-contact communication module, the second substrate can be easily placed in the housing portion of the housing by inserting the guide convex portion and the guide concave portion and moving the second substrate in the first direction. Can do.

  The housing may further include a contact surface provided with a fixing portion. The first substrate can be configured to be fixed to the fixing portion and to contact the contact surface from the other side in the first direction. In the case of such a non-contact communication module, it is easy to position the first substrate in the housing.

  The connecting portion can be configured to be disposed between the first substrate and the second substrate and within the range of the projected area of the second substrate. In the non-contact communication module of such an aspect, the connection portion is within the range of the projected area of the second substrate, and thus the size can be further reduced.

  The connecting portion can be configured to electrically and mechanically connect the first substrate and the second substrate. In this case, as described above, the second substrate mechanically connected to the first substrate is accommodated in the housing portion of the housing and positioned simply by fixing the first substrate to the fixing portion.

  The connection can be a board-to-board connector. In this case, the connection part can be configured to have a first connector and a second connector. The first connector can be mounted on the second surface of the first substrate, and the second connector can be mounted on the first surface of the second substrate. Either the first connector or the second connector is a male connector, the other is a female connector, and the male connector is fitted in the connection hole of the female connector in the first direction and is electrically connected to the female connector. It is possible to have a configuration. In the case of such a non-contact communication module, the first board and the second board can be easily and electrically connected to each other simply by fitting the male connector into the connection hole of the female connector in the first direction. Can do.

  The non-contact communication module according to any one of the aspects described above further includes a second antenna that is provided on the first surface of the first substrate and can transmit or receive power to the counterpart communication device in a non-contact manner. Is possible. In the case of the non-contact communication module of such an aspect, by setting the projected area of the first substrate to a minimum size capable of providing at least the first antenna and the second antenna, both the first substrate and the second substrate are used. Can be reduced.

  The non-contact communication module according to any one of the above aspects can further include a first circuit unit and a second circuit unit. The first circuit unit may be mounted on the second surface of the first substrate and electrically connected to the first antenna through the first substrate. The second circuit unit is mounted on at least one of the first surface and the second surface of the second substrate, and is electrically connected to the second antenna through the second substrate, the connection unit, and the first substrate. It is possible to have a configuration as described above. In the case of the non-contact communication module having such a configuration, the distance between the first circuit unit and the first antenna is reduced, and the electrical length between the first circuit unit and the first antenna is shortened. Loss is reduced. Further, the circuit electrically connected to the first antenna can be exchanged by exchanging the first substrate, and the circuit electrically connected to the second antenna can be exchanged by exchanging the second substrate. Can be exchanged.

  The second antenna can be substantially annular. The substantially annular shape includes an annular shape, a polygonal shape, an annular shape with a part broken, and a polygonal shape with a part broken. In this case, the first antenna can be arranged in the second antenna. In the case of the non-contact communication module of such an aspect, even if the outer shape of the second antenna is increased, it is not necessary to change the shape of the first antenna accordingly.

  The non-contact communication module according to any one of the above aspects can further include a magnetic sheet. The magnetic sheet may be configured not to be positioned between the first surface of the first substrate and the first antenna and to be disposed between the first surface of the first substrate and the second antenna. In the case of such a non-contact communication module, the power feeding or power receiving efficiency of the second antenna is improved by the presence of the magnetic sheet. On the other hand, since the magnetic sheet is not positioned between the first surface of the first substrate and the first antenna, the non-contact communication of the first antenna is hardly affected.

  The electronic device of the present invention includes the first non-contact communication module and the second non-contact communication module according to any one of the above-described aspects. The first contactless communication module and the second contactless communication module are arranged so that the first antenna of the first contactless communication module and the first antenna of the second contactless communication module are aligned in the first direction.

The module M1 as described above has the following technical features and effects.
Technical features and effects 1)
The projected areas in the ZZ ′ direction of the first substrate 100a and the second substrate 200a of the module M1 can be reduced, and as a result, the module M1 can be reduced in size. The reason is as follows.
When at least one first antenna 500a and at least one second antenna 700a are provided on the first surface 101a of the first substrate 100a, the projected area of the first substrate 100a is set to be at least one first as described above. The antenna 500a and at least one second antenna 700a can be provided with a minimum size. On the other hand, the projected area of the second substrate 200a is smaller than the projected area of the first substrate 100a, and is disposed within the range of the projected area of the first substrate 100a. For this reason, the projected areas of the first substrate 100a and the second substrate 200a fall within the projected area of the first substrate 100a. In addition, at least one first circuit unit 600a is mounted on the second surface 102a of the first substrate 100a, and at least one second circuit unit 800a is formed on the first surface 201a and the second surface 202a of the second substrate 200a. Since it is mounted on at least one surface and both circuit parts are distributed, it is not necessary to increase the projected area of the first substrate 100a in order to secure a mounting area for both circuit parts. From the above, since the projected areas in the ZZ ′ direction of both substrates are reduced, the projected area in the ZZ ′ direction of the module M1 can be reduced accordingly. In addition, when the connection part 300a is arrange | positioned in the range of the projection area of the 2nd board | substrate 200a between the 1st board | substrate 100a and the 2nd board | substrate 200a, it is outside the range of the projection area of the 2nd board | substrate 200a of the connection part 300a. Accordingly, the projected area of the module M1 in the ZZ ′ direction can be reduced.
When the second antenna 700a is not provided on the first surface 101a of the first substrate 100a, as described above, the projected area of the first substrate 100a is the minimum size that can provide at least one first antenna 500a. It can be. Also in this case, the projected areas of the first substrate 100a and the second substrate 200a are within the projected area of the first substrate 100a. Since at least one first circuit unit 600a can be mounted on the second surface 102a of the first substrate 100a, the first surface 201a of the second substrate 200a and / or the second surface 202a of the second substrate 200a, at least It is not necessary to increase the projected area of the first substrate 100a in order to secure a mounting area for one first circuit unit 600a. Also in this case, since the projected areas in the ZZ ′ direction of both substrates are reduced, the projected area in the ZZ ′ direction of the module M1 can be reduced accordingly.

Technical features and effects 2)
When the connection unit 300a electrically and mechanically connects the first substrate 100a and the second substrate 200a, the first substrate 100a and the second substrate 200a can be easily attached to the housing 400a as follows. Can do.
Since the second substrate 200a is electrically and mechanically connected to the first substrate 100a as described above, the first substrate 100a is inserted while the second substrate 200a is inserted into the housing portion 420a of the housing 400a from the Z direction side. By fixing the outer peripheral fixed portion 110a to at least one fixed portion 410a located outside the projected area of the second substrate 200a from the Z direction side, both the first substrate 100a and the second substrate 200a are once attached. It is fixed to the housing 400a.
In addition, when the housing 400a includes at least one guide portion 430a, the at least one guide portion 210a of the second substrate 200a is guided by the at least one guide portion 430a of the housing 400a. At least one fixing part 110a of the first substrate 100a mechanically connected is aligned with at least one fixing part 410a of the housing 400a. Therefore, it becomes easy to fix at least one fixing part 110a to at least one fixing part 410a.
Further, when at least one fixing portion 410a is provided on the edge, flange, convex portion or at least one guide portion 430a contact surface of the casing 400a, the fixing portion 110a on the outer peripheral portion of the first substrate 100a. Is fixed to at least one fixing portion 410a, and the outer peripheral portion of the first substrate 100a contacts the contact surface. Thereby, both the 1st board | substrate 100a and the 2nd board | substrate 200a are positioned within the housing | casing 400a at once. The same applies when the connecting portion 300a electrically connects the first substrate 100a and the second substrate 200a and another connecting portion electrically connects the first substrate 100a and the second substrate 200a. The technical features and effects of

Technical features and effects 3)
When at least one first circuit unit 600a is mounted on the second surface 102a of the first substrate 100a, the distance between at least one first circuit unit 600a and at least one first antenna 500a is short, Therefore, the signal loss between at least one first circuit unit 600a and at least one first antenna 500a is reduced, and the loss due to signal reflection and the jitter due to noise increase. Can be suppressed.

Technical features and effects 4)
At least one first circuit unit 600a is mounted on the second surface 102a of the first substrate 100a, and at least one second circuit unit 800a is formed on the first surface 201a and / or the second substrate 200a of the second substrate 200a. When mounted on the second surface 202a, the first circuit portion 600a for the first antenna 500a can be replaced by replacing the first substrate 100a, and by replacing the second substrate 200a, The second circuit portion 800a for the second antenna 700a can be replaced. When the connection part 300a is configured by a board-to-board connector, the first board 100a and the second board 200a can be easily connected to and released from each other, so that both boards can be exchanged more easily. In addition, the second circuit unit 800a for the second antenna 700a is mounted not on the first substrate 100a located near the boundary between the module M1 and the module M2, but on the second substrate 200a located far from the boundary. Therefore, the heat generated from the second circuit unit 800a is easily radiated in the Z ′ direction, and the heat radiating effect is improved.

Technical features and effects 5)
When the first substrate 100a of the module M1 and the first substrate 100b of the module M2 face each other in the ZZ ′ direction, the module 400 is removed from the support recess 440a of the module 400a by removing the housing 400b of the module M1. Since the first substrate 100a of M1 is exposed from the housing 400a, the first substrate 100a and the at least one fixing portion 410a of the housing 400a are released, and the first substrate 100a and the second substrate 200a are removed from the housing 400a. The first substrate 100a and the second substrate 200a can be easily detached from the housing 400a by moving the Z substrate relative to the Z direction.
