[0008]

According to the structure of the first aspect, the wiring of the electric equipment can be easily performed only by connecting the flexible board having the relay member to the electric equipment, so that the number of steps can be reduced, the cost is low, the structure is simple and the space is required. Maintenance becomes easy without it.

The relay member of the switch is connected to a flexible substrate to form a unit, and the transmitting side and receiving side modules of the multiplex transmission unit are housed in a housing, and a connector and an external connection connector are provided in the housing. Since the transmission box is configured in this manner, the modules on the transmission side and the reception side of the multiplex transmission unit can be mounted on the same panel as the switch, and the number of wirings to the outside can be reduced.

According to the second aspect of the present invention, the cost of the flexible substrate can be reduced, the cost can be reduced because the material is good, and the stress can be reduced because the flexible substrate is soft and easily bent. It is hard to give to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is an operation switch, 6 is a socket, and 7 is a flexible board.

A button portion 2 of an operation switch 1 as an electric device protrudes from an upper surface of a panel 4 of a control panel, and a switch body 3 is attached to a lower surface of the panel 4 by an attachment nut 5, and a terminal 3a is provided at a lower end. Is protruding.

The switch body 3 of the operation switch 1 is fitted on the inner surface of the socket 6 as a relay member, and the terminal 6a projecting from the lower end inside the socket 6 is connected to the terminal 3a of the operation switch 1. I have. The socket 6 is attached to the flexible board 7 and the terminals 6a of the socket 6
Are inserted through the terminal insertion holes 7a of the flexible substrate 7 and fixed by soldering or the like.

The flexible board 7 is a continuous flexible circuit board, and a circuit pattern is formed only on one side thereof. The terminal portion of the flexible substrate 7 is formed as a connector portion 8.

The transmission box 1 is provided on the panel 4 of the control panel.
0 is attached. That is, the transmission box 10
As shown in FIG. 3, a housing 9 is provided. A card connector 11 is provided on a front portion 9a of the housing 9, and an external connection connector 12 is provided on a lower surface portion 9b of the housing 9. . Modules 14 and 15 on the transmitting side and receiving side of the multiplex transmission unit 13 are housed in the housing 9, and these modules 14 and 15 are connected to the card connector 11.

The connector 8 at the terminal of the flexible board 7 is inserted and connected to the card connector 11. This connection state is shown in FIG. In the figure, the operation signal of the operation switch 1 is received by the module 14 of the multiplex transmission unit 13 and sent to the external PC 17 or the same type of multiplex transmission unit 13 by one signal line 16 to operate the load.

On the other hand, by operating the operation switch 1, the PC17-multiplex transmission unit (external)
13, the module 15 of the multiplex transmission unit 13 in the transmission box 10 receives a signal on one signal line 20,
It works to supply a lighting current to each lighting unit.

As described above, according to the present embodiment, the socket 6 of the operation switch 1 is connected to the flexible substrate 7 to form a unit, and the transmitting and receiving modules 14 and 15 of the multiplex transmission unit 13 are connected to the housing 9. This case 9
The transmission box 10 is configured by providing a connector 11 and an external connection connector 12 to the multiplex transmission unit 1.
3, the transmitting and receiving modules 14 and 15 can be mounted on the same control panel 4 as the operation switch 1.

Further, since a single-sided flexible substrate having a circuit pattern formed only on one side thereof is used as the flexible substrate 7, the cost of the flexible substrate 7 is reduced. In addition, since the flexible board 7 is soft and easily bent, stress is hardly applied to the connector portion and the like.

[0021]

As described above, according to the present invention, a relay member is provided for each of a plurality of switches, these relay members are connected to a flexible substrate, and a terminal portion of the flexible substrate is formed as a connector portion. The transmission side and reception side modules are housed in a housing, and a connector and an external connection connector are provided in this housing to constitute a transmission box,
Since the connector section of the flexible board is connected to the connector of the transmission box, wiring of the electrical apparatus can be easily performed only by connecting the flexible board including the relay member to the electrical apparatus, so that the man-hour can be reduced and the cost can be reduced, and the structure can be reduced. But it is simple and does not require space, making maintenance easy.

The relay member of the switch is connected to a flexible board to form a unit, and the transmitting and receiving modules of the multiplex transmission unit are housed in a housing, and a connector and an external connection connector are provided in the housing. Since the transmission box is configured in this manner, the modules on the transmission side and the reception side of the multiplex transmission unit can be mounted on the same panel as the switch, and the number of wirings to the outside can be reduced.

Further, according to the present invention, in the connection structure for electric equipment of the first aspect, since the single-sided flexible substrate having the circuit pattern formed only on one side thereof is used for the flexible substrate, the flexible substrate is inexpensive. In addition, since the material can be easily removed, the cost can be further reduced and the cost can be reduced.
