Description

  The present invention relates to a waterproof switch used for flashing lighting etc. in a rainy place such as outdoors or on the side of a store.

Waterproof switches used outdoors or in rainy places on the side of a house are waterproof packings to prevent electrical leakage or electric shock due to rainwater, etc. It is isolated by electrical insulation and prevents water from entering the operation section and the mounting wall. In order to transmit the operation of the surface operation unit for operating the switch to the built-in switch, the portion corresponding to the operation unit of the waterproof packing is required to be flexible, and the thickness of the packing is also reduced. On the other hand, the outer periphery is required to have a thickness that can absorb the unevenness of the wall in order to prevent water from entering the wall, so that the thickness becomes thick and the packing requires a thin part and a thick part. Deformation and dimensions are likely to go wrong. In addition, the built-in switch handle and the surface operation section can be structurally spaced, and packing is interposed between them, so even if the built-in switch with an indicator light is used, it is difficult for the indicator light to reach the surface operation section. It is difficult to understand the lighting state of the switch indicator lamp, and conveniences such as a power source display of a switch with a lighting indicator that is often used indoors, a switch position display, and an energization display that displays a load energization state are not utilized.

FIG. 2 is a perspective view showing a component configuration of a waterproof switch having no general display function, and FIG. 3 is a side sectional view. The structure of a general waterproof switch in which a built-in switch blinks with an operation handle on the surface will be described. Reference numeral 1 denotes a surface plate, and a surface operation handle 11 is incorporated in the hollow window 1a. A rotation fulcrum shaft 11a is formed as 1d constituting the upper half bearing of the surface plate 1 and 12c constituting the lower half bearing of the waterproof packing 12. It can be assembled and rotated. The surface operation handle 11 and the switch handle 13a of the built-in switch 13 are transmitted to the built-in switch by the rotation operation of the surface operation handle via the flexible thin portion 12a of the waterproof packing 12, and the switch is blinked. The built-in switch 13 is fixed by a claw 6a of the mounting plate 6 and a step portion 13b on the surface of the switch, and is screwed through the mounting plate hole 6b and the waterproof packing hole 12f with the surface operation handle 11 and the waterproof packing 12 together with the surface plate. 1 is fixed. The clearance between the surface operation handle 11 and the hollow window 1a of the surface plate 1 is such that the thin wall portion 12a of the waterproof plate is sandwiched between the surface plate 1 by the mounting plate 6 and can have a waterproof function. The stepped portion 1e on the outer periphery of the plate and the outer peripheral groove 12d of the waterproof packing 12 are fitted to each other, and a waterproof switch incorporated in the surface plate 1 is attached to a wall or the like to give a waterproof function to the outer periphery. A mounting frame 7 made of an electrical insulator has a pair of long holes 7c attached to a switch box on the wall surface with box screws, a built-in switch 13 incorporated in the surface plate 1 with screws 10, a waterproof packing 12, and a surface operation handle 11. The waterproof switch constituted by the screw is attached to a construction material such as a switch box by being screwed into the screw hole 7b of the mounting frame 7 with a screw 9. With such a configuration, the switch handle 13a of the built-in switch and the surface operation handle 11 sandwich the thin part 12a of the waterproof packing and can be spaced apart from each other, so that the switch with indicator light is incorporated in the built-in switch, and the surface operation handle is translucent. Even when the display window is attached, it is difficult for the light of the indicator lamp to reach the surface operation handle, and it is difficult to obtain sufficient brightness when the display window of the surface operation handle is viewed from the front side. In addition, the waterproof packing is required to have a wall thickness with respect to the uneven wall at the outer peripheral portion, and the portion corresponding to the surface operation handle is thin due to flexibility, and the packing formability is poor, and problems such as deformation are likely to occur. The protrusion 7a of the attachment frame 7 is a protrusion for confirming that the insulator attachment frame is incorporated from the viewing hole 1c of the surface plate 1 through the hole 12e of the waterproof packing 12.

FIG. 1 is a perspective view of parts constituting the waterproof switch of the present invention, and FIG. 4 is a side sectional view thereof. The surface plate 1, the built-in switch mounting plate 6 and the mounting frame 7 have exactly the same structure as in FIGS. Reference numeral 2 denotes a surface operation handle that fits into the hollow window 1a of the plate, and has a pair of fulcrum shafts 2a that rotate, and a step hole 2b that incorporates a translucent display lens 3 at the center of the surface. The display lens 3 has a leg portion 3a and a display surface 3b extending through the operation handle 2 and extending to the vicinity of the display window 5b of the switch handle 5a of the built-in switch 5. 4 is a translucent material that prevents rainwater and the like from entering the gap between the hollow window 1a of the plate 1 and the operation handle 2 and transmits the light of the indicator lamp of the built-in switch 5 to the display lens 3 incorporated in the surface operation handle. A flexible thin-walled portion 4a for transmitting the rotation operation of the surface operation handle 2 to the switch handle 5a of the built-in switch 5 by the operation unit packing, 4c constituting a lower half bearing of the fulcrum shaft 2a of the operation handle 2, a built-in switch 5 has a hole 4b for assembling the built-in switch 5, the operation portion packing 4 and the surface operation handle 2 to the plate 1 with four screws 10. The built-in switch 5 is lit when the switch is OFF to display the power supply, or has a built-in indicator lamp that is lit when ON and displays the energization. The illumination part 5b of the switch handle 5a illuminates when the switch is lit. indicate. 8 is a peripheral packing having the same structure as the packing 12 shown in FIGS. 2 and 3 except that it has a hollow space 8b for storing a built-in switch in the center, and has a waterproof property on the outer periphery of the plate by fitting the groove 8a and the outer peripheral step 1e of the plate 1. It is The proposed switch is also constructed by attaching the proposed waterproof switch incorporated in the plate 1 with a pair of screw holes 8d to the mounting frame 7 with screws 9 and attaching the mounting frame to a switch box or the like through the long hole 7c of the mounting frame 7. Fixed to the material. With such a configuration, the light of the indicator lamp of the illumination portion 5b of the switch handle 5a of the built-in switch 5 is not much due to the leg portion 3a of the display lens 3 incorporated in the operation handle 2 via the thin portion 4a of the operation portion packing. The display surface 3b of the display lens 3 can be illuminated without being dimmed, so that it can be easily discriminated from the surface, and a power display when the switch is OFF, an energization display when the switch is ON, and the like are possible. As a result, the power display, the switch position display, and the load blinking state can be easily determined even in a dark place.

According to the first aspect of the present invention, the built-in switch lighting display function can be provided to the waterproof switch surface operation handle as it is, and the power display that lights when the switch is turned off to indicate that the power is on is dark. It is also possible to display the position of the switch at the place and to easily operate the switch. Moreover, when the switch is turned on, it is displayed that the connected load is energized, and it is possible to prevent forgetting to turn off the lighting. Furthermore, by separating the waterproof packing into a thin and small operation part and a thick outer peripheral packing, it becomes easier to form each, and there are few materials for the operation part packing that require expensive translucency and flexibility. Well, the price is cheaper.
