Abstract
A coupler which is fixed to a meter case (lower case) includes a sleeve which penetrates the case, and a flange which overhangs from the sleeve to a circumference thereof. An annular groove holding a seal ring is provided in the flange. A step as a mark is provided on an outer circumference of the sleeve in order that an adequate compression amount of the seal ring can be recognized from the external appearance. This step is aligned with an outer surface of the lower case when the seal ring is compressed up to the adequate compression amount. This configuration makes it possible to easily recognize, from an external appearance, whether or not a waterproof tight-sealing level of a coupler penetrating a meter case is adequate.
Claims20
A control panel apparatus including a cabinet housing an electric circuit;
- and a coupler which is for connecting an electric wiring from the outside to the electric circuit, and which is composed of a sleeve and a flange, the sleeve penetrating a mounting hole provided in the cabinet, the flange overhanging from the sleeve in a direction along an outer circumference of the flange, the control panel apparatus comprising:
- an elastic sealing member arranged between the flange and an inner surface of the cabinet;
- fastening means which presses the flange against the inner surface of the cabinet;
- and
- a mark put on an outer circumferential surface of the sleeve so as to be aligned, on the same plane, with as an outer surface of the cabinet in a portion of the mounting hole, in a state where the fastening means presses the flange until a compression amount of the elastic sealing member becomes an intended adequate value.
A control panel apparatus including a cabinet housing an electric circuit;
- and a male coupler which is for connecting an electric wiring from the outside to the electric circuit, and which is composed of a sleeve and a flange, the sleeve penetrating a mounting hole provided in the cabinet, the flange overhanging from the sleeve in a direction along an outer circumference of the flange, the control panel apparatus comprising:
- an elastic sealing member arranged between the flange and an inner surface of the cabinet;
- fastening screws which press the flange against the inner surface of the cabinet;
- and
- a mark put on an outer circumferential surface of the sleeve so as to be aligned, on the same plane, with as an outer surface of the cabinet in a portion of the mounting hole, in a state where the fastening screws press the flange until a compression amount of the elastic sealing member becomes a predetermined value.
