The interface board 1 will be described with reference to FIGS. The interface board 1 is an interface board for connecting between a control device (not shown) and each device to be controlled.

The interface board 1 has an interface board unit 3 that allows a plurality of cable-side connectors to be connected in a limited space, and a housing 2 that accommodates other devices (not shown) inside. The interface board unit 3 includes three interface boards 8A, 8B, and 8C, which will be described later, and the interface board unit 3 is attached to the housing 2 via hinges (not shown) so that it can be opened and closed. FIG. 1 shows a state in which the interface board unit 3 is closed and housed in the housing 2, which is the form when the interface board 1 normally functions. 2 shows a state in which the interface board unit 3 is opened with respect to the housing 2, exposing the interface board 8A and the interface board 8B. Cable-side connectors 6A and 6B, which will be described later, are connected to the interface boards 8A and 8B. You can do the work to put it on and take it off.

As shown in FIG. 4, cable-side connectors 6A, 6B, 6C attached to one end of connector cables 5A, 5B, 5C can be attached to and detached from the mounting surfaces 81A, 81B, 81C of the respective interface boards 8A, 8B, 8C. A plurality of board-side connectors 7A, 7B, and 7C are mounted. Connector cables 5A, 5B, and 5C connect the control device (not shown) and the interface board 1, and connect the control device to each device to be controlled, such as a control console, a station terminal, a base station radio device, and a siren sounding device. A connector (not shown) is attached to the other end of the connector cable 5 to connect to the board of the control device. In FIG. 1, only the interface board 8C is visible among the three interface boards 8A, 8B, and 8C. In the following description, the cable-side connectors 6A, 6B, 6C, the board-side connectors 7A, 7B, 7C, the interface boards 8A, 8B, 8C, and the mounting surfaces 81A, 81B, 81C of the respective interface boards 8A, 8B, 8C will be described as the cable-side connector 6, the board-side connector 7, the interface board 8, and the mounting surface 81, omitting the letters A, B, and C unless necessary. The mounting surface 81 of the interface board 8 refers to the surface of the interface board 8 on which the board-side connector 7 is mounted, and the other end surface refers to the surface opposite to the mounting surface 81 . and

The interface board 1 is arranged in a first arrangement and a second arrangement. Although the details will be described later, the first arrangement is a state in which the mounting surfaces 81 of the two interface boards 8 face each other and are arranged in parallel. It becomes a form in which the body 2 is stored. Here, the mounting surfaces 81 of the two interface boards 8 do not necessarily have to be parallel as long as they face each other. The second arrangement means that the mounting surfaces 81 of the two interface substrates 8 do not face each other due to the movement of one of the two interface substrates 8 , and the mounting surfaces 81 of the interface substrates 8 do not face each other. It means a state in which the cable-side connector 6 can be inserted/extracted from the board-side connector 7 mounted on the cable. 1 shows the state of the first layout of the interface board 1, and FIG. 2 shows the state of the second layout of the interface board 1. As shown in FIG.

When the cable-side connector 6 is connected to the board-side connector 7 arranged on the mounting surface 81 of each interface board 8 , the cable-side connector 6 is attached perpendicular to the mounting surface 81 of the interface board 8 . Here, when the cable side connector 6 is attached so as to be perpendicular to the mounting surface 81 of the interface board 8, it means that the insertion direction of the cable side connector 6 to the board side connector 7 is with respect to the mounting surface 81. It is a vertical direction, and the side surface of the cable-side connector 6 is perpendicular to the mounting surface 81 when the cable-side connector 6 is connected to the board-side connector 7 . However, the direction in which the cable-side connector 6 is attached to the mounting surface 81 of the interface board 8 is not limited to the vertical direction, and may be any crossing direction.

As shown in FIG. 2, on the mounting surface 81B of the interface board 8B, 12 board-side connectors 7B are arranged in two rows from the longitudinal end side of the interface board 8B. The connectors 7B are arranged so that their long sides face each other, and each row is arranged so that the short sides of the board-side connectors 7B face each other. Six board-side connectors 7A are arranged on the mounting surface 81A of the interface board 8A, and are arranged in a row on the board-side connectors 7A so that the long sides of the board-side connectors 7A face each other. As shown in FIG. 1, on the mounting surface 81C of the interface board 8C, eight board-side connectors 7C are arranged in two rows from the lower end side of the interface board 8C. are arranged on the board-side connector 7C so that the long sides of the lines face each other, and each row is arranged so that the short sides of the board-side connector 7C face each other.

3 to 6 show the interface board unit 3, which is an interface board 8A and an interface board 8B. Note that the connector cable 5C, the cable-side connector 6C, the board-side connector 7C, and the interface board 8C, which are fixed integrally with the interface board 8B, are removed. 3 and 5 show the state of the first arrangement, FIGS. 4 and 6 show the state of the second arrangement, FIGS. 3 and 4 are perspective views of the interface board unit 3, and FIGS. 3 is a front view of the board unit 3 as viewed from the front; FIG.

As shown in FIGS. 3 and 4, the interface board unit 3 has a base frame 4 attached to a board fixing frame 13 for fixing the interface board 8B. 8A is opened and closed, and includes a moving frame 15 capable of inserting and removing the cable-side connector 6A from the board-side connector 7A. In the first arrangement, as shown in FIG. 5, the mounting surface 81A of the interface board 8A and the mounting surface 81B of the interface board 8B are arranged to face each other in parallel. In the first arrangement, the cable-side connector 6A is connected to the interface board 8A and the cable-side connector 6B is connected to the interface board 8B, that is, the cable-side connector 6A is connected to the board-side connector 7A and the cable-side connector 6B is connected to the board-side connector 7B, there is a space between the cable-side connector 6A connected to the mounting surface 81A of the interface board 8A, which is one of the interface boards, and the cable-side connector 6A adjacent to the same connector. , the cable-side connector 6B connected to the mounting surface 81B of the interface board 8B, which is the other interface board, is inserted into the cable-side connector 6B. The cable side connector 6A is arranged so as to enter the space between the cable side connector 6B and the cable side connector 6A, so that the cable side connector 6A and the cable side connector 6B do not interfere with each other.

Therefore, in the first arrangement, the distance D between the facing mounting surface 81A of the interface board 8A and the mounting surface 81B of the interface board 8B is the distance from the mounting surface 81A to the upper end surface 23, which is the upper end of the cable-side connector 6A. It is smaller than L1+L2 which is the sum of the height L1 and the height L2 from the mounting surface 81B to the upper end surface 23 which is the upper end of the cable side connector 6B. Therefore, in the first arrangement, the cable-side connector 6A cannot be inserted/extracted from the board-side connector 7A, and the cable-side connector 6B cannot be inserted/extracted from the mounting surface 81B. Since the space of the distance D between the interface board 8B and the mounting surface 81B can accommodate the cable side connector 6A connected to the mounting surface 81A and the cable side connector 6B connected to the mounting surface 81B, the interface The size of the board unit 3 itself and the size of the interface board 1 can be made compact. The distance D between the mounting surface 81A and the mounting surface 81B is the height L1 from the mounting surface 81A to the upper end surface 23 of the cable side connector 6A and the height L1 from the mounting surface 81B to the upper end surface 23 of the cable side connector 6B. At the height L2 of , D≦L1+L2.

As shown in FIG. 4, in the second arrangement, a moving frame 15 to which interface board 8A, which is one of two interface boards 8A and 8B, is mounted, is attached to a rotating frame 15 mounted on moving frame 15. This is a state in which the moving frame 15 is rotated by 90° from the first disposition state by rotating the shaft 10 as a support shaft. Therefore, in the first arrangement, the mounting surface 81A of the interface board 8A faces the mounting surface 81B of the interface board 8B, but in the second arrangement, the mounting surface 81A of the interface board 8A faces the interface board. The mounting surface 81A and the mounting surface 81B do not face the mounting surface 81B of 8B, but are arranged at a position where the angle formed by the mounting surface 81A and the mounting surface 81B is 90°. Therefore, in the first arrangement, the cable side connector 6A could not be inserted/extracted from the board side connector 7A, and the cable side connector 6B could not be inserted/extracted from the board side connector 7B. It becomes easy to insert and remove the cable side connector 6A from the connector 7A and to insert and remove the cable side connector 6B from the board side connector 7B.

In the second arrangement, the moving frame 15 has fixing members 11 so that the moving frame 15 can be fixed in a 90° rotated state. One end of the fixed member 11 is rotatably supported by the moving frame 15, and as shown in FIG. 81A is fixed at a position of 90° to the mounting surface 81B. In the first arrangement, the base frame 4 and the moving frame 15 are fixed by fixing means (not shown) so that the mounting surface 81A of the interface board 8A and the mounting surface 81B of the interface board 8B face each other. be.

Further, as shown in FIG. 6, in the second arrangement, the cable-side connector 6A connected to the board-side connector 7A of the interface board 8A and the cable-side connector 6A adjacent to the cable-side connector 6A are inserted into the space. By rotating the moving frame 15, the cable-side connector 6B can secure a space between the adjacent cable-side connectors 6A and 6A. The operation of inserting and withdrawing from 7A is facilitated. The same applies to the cable side connector 6B.

7A and 7B are AA cross-sectional views of the interface board unit 3 in FIGS. 5 and 6, FIG. 7A showing the first embodiment and FIG. 7B showing the second embodiment. 7A and 7B, the cable-side connector 6 indicated by a solid line shows a cross section of the cable-side connector 6B connected to the board-side connector 8B of the interface board 8B in the first arrangement, and the cable-side connector 6 indicated by a two-dot chain line 4 shows a cross-section of the cable-side connector 6A connected to the board-side connector 8A of the interface board 8A in the first arrangement.

As shown in FIG. 7A, in the first embodiment, 12 cable-side connectors 6B are installed, and in each row, 6 cable-side connectors 6B are arranged so that their sides face each other. Six cable-side connectors 6A are arranged on the mounting surface 81A of the interface board 8A, and the respective cable-side connectors 6A are arranged so that the side surfaces thereof face each other. In the first arrangement, the cable side connectors 6A are arranged between the side surfaces of the adjacent cable side connectors 6B such that the cable side connectors 6A and the cable side connectors 6B are staggered. Therefore, the cable-side connector 6A and the cable-side connector 6B can be placed in the first arrangement state without interference, and the distance between the interface board 8A and the interface board 8B in the first arrangement can be shortened. and the interface board 1 can be made compact.

The number is larger in the state of the first arrangement than in the state of the second arrangement. In FIG. 7A, in the state of the first arrangement, the number of cross-sections of the cable-side connector 6 is 12 cross-sections of the cable-side connector 6A and 6 cross-sections of the cable-side connector 6B, totaling 18. In the second arrangement, the interface board 8A rotates so that the cable-side connectors 6A indicated by the chain double-dashed lines do not appear. There are 12 cross sections of 6B, which is less than the state of the first arrangement.

A second embodiment is shown in FIG. 7B. The second embodiment differs from the first embodiment only in the arrangement of the cable-side connector 6A and the cable-side connector 6B, and the rest of the configuration is the same as the first embodiment. In the second embodiment, the cable side connector 6B is arranged in the space formed between the adjacent cable side connectors 6A and 6A, and between the adjacent cable side connectors 6B and 6B. A cable-side connector 6A is arranged in the formed space. Therefore, the cable-side connector 6A and the cable-side connector 6B can be placed in the first arrangement state without interference, and the distance between the interface board 8A and the interface board 8B in the first arrangement is shortened. and the interface board 1 can be made compact. The rotation shaft 10 is arranged so that the axis of the rotation shaft 10 is parallel to the short side surface of the board-side connector 7, so that when the moving frame 15 is rotated, the side surface of the cable-side connector 6A and the cable-side connector 6A are rotated. Since it moves while the side surface of 6B is kept parallel, the cable-side connector 6A and the cable-side connector 6B do not come into contact with each other.

In the present invention, at least two interface boards 8A and 8B are provided, and a plurality of board-side connectors 7 are mounted side by side on the mounting surfaces 81A and 81B of the interface boards 8A and 8B. The cable-side connector 6 is vertically connected to the mounting surfaces 81A, 81B of the interface boards 8A, 8B, and the two interface boards 8A, 8B are arranged in parallel so that the mounting surfaces 81A, 81B face each other. , the cable-side connector 6 on the other interface board 8B may be arranged in the space formed between the cable-side connector 6 on the other interface board 8A. In the space formed between the cable-side connectors 6 on the adjacent interface board 8A, the space formed between the adjacent cable-side connectors 6B, 6B as shown in FIG. Also included is a space formed between the obliquely arranged cable side connectors 6B, 6B, rather than a space formed between the sides of each other as shown in FIG. 7A.

In the second embodiment, as in the first embodiment, the mounting surface of the interface board 8B is connected with the cable side connectors 6A and 6B connected to the board side connectors 7A and 7B mounted on the interface boards 8A and 8B, respectively. The number of cross sections of the cable side connectors 6 arranged on the mounting surface in the cross section when the cable side connectors 6A and 6B are cut along a virtual plane (AA cross section) parallel to 81B is the second arrangement. There are more states in the first arrangement than states. In FIG. 7B, in the state of the first arrangement, the number of cross sections of the cable-side connector 6 is 3 cross-sections of the cable-side connector 6A and 4 cross-sections of the cable-side connector 6B, for a total of 7. In the second arrangement, the interface board 8A rotates so that the cable-side connectors 6A indicated by the chain double-dashed lines do not appear. There are 4 cross sections of 6B, which is less than the state of the first arrangement.

In the first embodiment and the second embodiment, the mounting surface 81A of the interface board 8A and the mounting surface 81B of the interface board 8A are arranged facing each other in parallel from the first arrangement in which the mounting surface 81A of the interface board 8A is arranged in parallel. and the mounting surface 81B of the interface board 8B do not face each other, the movement frame 15 to which the interface board 8A is attached is rotated. For example, rails are provided between the base frame 4 and the moving frame 15 so that the moving frame 15 can be slidably moved. The mounting surface 81B may not face the mounting surface 81B. In the second arrangement, the mounting surface 81A of the interface board 8A and the mounting surface 81B of the interface board 8B do not face each other, but the frame to which the mounting surface 81A of the interface board 8A is attached is completely separated from the frame to which the interface board 8B is attached. It is sufficient if they are partially connected instead of being connected to each other. By doing so, it is possible to easily change from the first arrangement to the second arrangement, and from the second arrangement to the first arrangement.

Although the foregoing has been described with reference to a limited number of embodiments, the scope of rights is not limited thereto, and modifications of the embodiments based on the above disclosure will be obvious to those skilled in the art.
