Description

  The present invention relates to a terminal structure in which a plurality of modules are arranged in multiple layers and the modules are connected to each other.

  For example, a module on which an electronic component such as a hybrid IC is mounted has a rectangular shape, and a plurality of terminals protrude from the side surface portion (see, for example, Patent Document 1). When two modules are connected, the modules are arranged close to each other in a plan view, and terminals protruding from the side surfaces of the respective modules are connected. In such a connection structure between modules, since the terminal protrudes from the side surface portion of the module, each module must be arranged in a plane, and space is required when installing on the board. There is a problem.

  Therefore, it is desirable to arrange a plurality of modules in a multilayered manner. However, in the case of arranging a plurality of modules in a multilayered manner, the inter-terminal connection between the modules is complicated, and the feasibility is poor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a connection state of two modules employing a terminal structure according to an embodiment of the present invention. As shown in FIG. 1A, a plurality of connection terminals 14 are provided between the first module 11 and the second module 12, and are respectively provided on the side surface of the first module 11 and the side surface of the second module 12. Connected. A plurality of terminals 13 are provided on the side surface of the first module 11 opposite to the second module 12, and the terminal 15 is provided on the side surface of the second module 12 opposite to the first module 11. Is provided.

  Therefore, the first module 11 can perform data transmission and power transmission with the second module 12 through the connection terminal 14, and data with other electronic devices through the terminal 13. Transmission and power transmission are possible. Similarly, the second module 12 can perform data transmission and power transmission with the first module 11 via the connection terminal 14, and can communicate with other electronic devices via the terminal 15. Data transmission and power transmission are possible.

  As shown in FIG. 1B, the connection terminal 14 has an L-shaped (broken line-shaped) cutout portion 21 formed at the center, and one end of the cutout portion 21 is connected to the bent portion 22. The other end is a bent portion 23. Further, between the two bent portions 22 and 23, a portion that is not bent by these bent portions 22 and 23 is a protruding portion 14a (a protruding terminal). Further, when the distance L1 from the side surface of the first module 11 to the bent portion 22 is set and the distance L2 from the side surface of the second module 12 to the bent portion 23 is set, L1 = L2.

  Then, the connecting terminal 14 is bent at a substantially right angle at the bent portion 22 and further bent at a substantially right angle at the bent portion 23, whereby the connecting terminal 14 is bent 180 degrees as a whole as shown in FIG. As shown in the plan view of FIG. 2A and the side view of FIG. 2B, the second module 12 can be overlaid on the upper side of the first module 11 (multilayered state).

  Therefore, it is possible to install the two modules 11 and 12 in a smaller space than the case where they are installed in a plane, and the terminal 13 connected to the first module 11 and the terminal connected to the second module 12. 15 can be used to connect to other electronic devices. Further, as shown in FIGS. 2 and 4, the protruding portion 14 a that is not bent by the two bent portions 22 and 23 serves as a terminal protruding from the side surface of the first module 11. By using it, it is possible to connect to other electronic devices.

  Thus, in the terminal structure of the module according to this embodiment, the L-shaped notch 21 is formed in the connecting terminal 14 that connects the first module 11 and the second module 12, and the connecting terminal 14 is connected to the connecting terminal 14. Since the first module 11 and the second module 12 are multi-layered by bending the two bent portions 22 and 23, multi-layering can be achieved with a simple configuration. Further, the installation space can be reduced as compared with the case where the two modules 11 and 12 are installed in a plane. Further, the projection 14a is formed by bending the connecting terminal 14, and the projection 14a can be used as a terminal for connecting to another electronic device. Therefore, flexibility in connection with another electronic device is provided. Can be increased.

  In the present embodiment, the terminal structure for connecting the two modules 11 and 12 has been described as an example. However, it is possible to connect three or more modules using a connecting terminal. In this case, the module can be stacked in three or more stages, and further space saving can be achieved.

  In the above-described embodiment, the example in which the bent portions 22 and 23 provided on the connecting terminal 14 are bent at a substantially right angle has been described, but the present invention is not limited to a right angle. For example, the two modules 11 and 12 can be multi-layered by bending at an angle of 80 degrees at the bent portion 22, bending at an angle of 100 degrees at the bent portion 23, and bending an angle of 180 degrees as a whole. is there. In this case, the distances L1 and L2 shown in FIG. 1B are L1> L2.

  Next, a modified example of the present invention will be described. FIG. 3 is an explanatory diagram illustrating a configuration of the connection terminal 31 according to the modification. As shown in FIG. 3, the connection terminal 31 has a U-shaped (broken line shape) notch 32 formed at the center. One end of the notch 32 is a bent portion 33, 34, and the other end is a bent portion 35. A portion that exists between the bent portions 33, 34, and 35 and is not bent by the bent portions 33 to 35 is a protruding portion 31 a (projected terminal). Further, the distance L3 from the side surface of the first module 11 to the bent portions 33, 34 and the distance L4 from the side surface of the second module 12 to the bent portion 35 are set to be equal.

  Then, the connecting terminal 31 is bent at a substantially right angle at the bent portions 33 and 34 and further bent at a substantially right angle at the bent portion 35 so that the connecting terminal 31 is 180 degrees as a whole as shown in FIG. The first module 11 and the second module 12 can be bent (stacked state).

  Thus, also in the terminal structure of the module according to the modified example, the first module 11 and the second module can be obtained by bending the connecting terminal 31 at the bent portions 33, 34, and 35 as in the above-described embodiment. Since 12 is multilayered, the installation space can be reduced as compared with the case where two modules are installed in a plane. Further, the protruding portion 31a is formed by bending the connecting terminal 31, and the protruding portion 31a can be used as a terminal for connecting to another electronic device. Therefore, flexibility in connection with another electronic device is provided. Can be increased.

  As described above, the terminal structure of the module of the present invention has been described based on the illustrated embodiment. However, the present invention is not limited to this, and the configuration of each part is replaced with an arbitrary configuration having the same function. be able to.
