The plate covers 13, 14, 15 are fitted therein, and only a plurality of types of plate covers 13, 14, 15 corresponding to the wiring devices 3, 4, 5 need to be prepared. It is more economical than the conventional one in which the whole instrument plate is manufactured integrally.

In particular, operation parts 31, 41, 51, indicator lamps 52, etc. arranged on the surface such as control switches 4 and 5 for equipment to which a weak electric wire for supplying a control signal from the equipment is connected. This is extremely effective when the number and arrangement of the wiring devices are many, and furthermore, as in the present embodiment,
This is advantageous when the mounting positions 4 and 5 can be freely selected.

Further, according to the present embodiment, the engaging portions 23, 24, 25 of the wiring device mounting frame 2 at the mutually facing edges 115, 115 extending in the longitudinal direction in the opening 111 of the plate frame 11. Locking part 1 at the position corresponding to
Deformation prevention walls 117 extending along 16 are provided integrally. Therefore, even if the wiring devices 3, 4, and 5 are fitted into the long plate frame 11, the plate frame 1

Further, the frame main body 112 of the plate frame 11 is brought into contact with the surface of the wiring device mounting frame 2 so as to protrude from the inner peripheral surface of the vertical frame 113 vertically extending from the outer peripheral edge of the frame main body 112. By engaging the joint 114 with the step 27 formed on the outer periphery of the wiring device mounting frame 2, it can be fixed to the wiring device mounting frame 2. Covers 13, 14, 15
The opposite edges 131 of the plate covers 13, 14, 15 are also attached to locking portions 116 formed on the opposite edges 115, 115 extending in the longitudinal direction of the opening 111.
Locking claws 132, 142, 1 protruding from 141, 151
52 may be locked.

In this embodiment, the case where the wiring devices 3, 4, and 5 are mounted on the three mounting portions 213, 214, and 215 formed on the wiring device mounting frame 2 has been described. The number, types, and mounting positions of the wiring devices are arbitrary, and it is not necessary to mount the wiring devices in all of the mounting portions 213, 214, and 215. The operation parts 31, 41, and
Exposure holes 133, 143, 153 such as 51 and indicator light 52
A blind plate cover (not shown) in which is not formed is used.

[0029]

As described above, according to the present invention, the plate covers for wiring devices having different numbers and arrangements of the operation parts arranged on the surface are fitted into the common plate frame, and are arranged on the surface. The manufacturing cost may be lower and storage and management may be excellent as compared with the conventional one in which the number and arrangement of the operating units to be operated are differently manufactured for each wiring device.

The mounting of the plate frame to the wiring device mounting frame is performed by bringing the frame main body of the plate frame into contact with the surface of the wiring device mounting frame, and vertically hanging from the outer peripheral edge of the frame main body. It is only necessary to engage with the step formed on the outer periphery of the mounting frame of the wiring device mounting projecting from the mounting portion, and the mounting operation is easy and reliable, and each plate cover has the length of the opening of the plate frame. It is extremely simple and reliable to lock the locking claws projecting from the opposite edges of each plate cover to the locking portions formed on the opposite edges extending in the direction.

Further, deformation preventing walls extending along the locking portions are integrally formed at positions corresponding to the locking portions in the wiring device mounting frame at opposite edges extending in the length direction in the opening portion of the plate frame. Therefore, even if the wiring instrument is fitted into the long plate frame, the plate frame is not bent and its shape can be maintained to reliably hold the plate cover.

Further, even when a plurality of different types of wiring devices are mounted, it is possible to cope with the problem by selecting and fitting the corresponding plate cover, and the mounting position of the wiring device once installed. Can be easily coped with by changing the plate cover.
