BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure of an electric device, and more particularly to a housing structure of an electric device in which a switch window is protected.

[0002]

2. Description of the Related Art FIG.
As shown in (a) and (b), when used as a desktop type or wall-mounted type chime adapter, a plurality of switches 2 involved in the operation of the electric device 1 in a housing 40 housing the electric device 1. , 2,..., And switch windows 30,
30, ...

In general, the switches 2, 2,... Are not frequently switched, but the switches 2, 2,... Are designed to be easily operated when used on a table or on a wall, so that the switches 2, 2,. It is installed at a position corresponding to 40 s or a position corresponding to the upper surface 40 u of the housing 40 when used on a wall.

[0004]

In the housing structure of the conventional electric device, the position corresponding to the side surface 40s of the housing 40 at the time of using the desktop or the position corresponding to the upper surface 40u of the housing 40 at the time of using the wall is directly defined as the side surface or the upper surface. Touching the flow of outside air, the switch windows 30, 30,... Are susceptible to intrusion of dust or the like gradually, and the dust or the like causes poor contact of the internal electrical equipment, thereby shortening the life of the product. Was.

[0005]

The present invention has been made to solve the conventional problems, and has as its object to provide a housing structure of an electric device having a removable cover for covering a switch window.

[0006]

In order to achieve this object, a housing structure of an electric device according to the present invention comprises a housing containing an electric device and a switch involved in the operation of the electric device. A switch window for exposing the switch housed in the body and operating the switch from the outside, a cover covering the switch window after the switch is operated from the outside and fixed to the housing, and a detachable cover for fixing the cover to the housing. With a stop,
A stopper is fitted to fix the cover to the housing, and has a fitting hole formed in the housing and a fitting hole formed in the cover. And a penetrating portion penetrating the fitting hole drilled in the cover, the penetrating portion has a shaft portion and a fin, and the fin is fitted from the fitting hole. Then, the cover is fixed to the housing with a structure that opens inside the housing, and when the knob is pulled up, the fins narrow and become integral with the shaft, the stopper can be pulled out from the fitting hole, and the The integrated cover can be removed.

[0007]

In the housing structure of this electric device, the stopper is removed only when the switch is operated, and the cover covering the switch window can be freely fixed to the housing in a normal state, so that dust and the like enter the housing. Is prevented, the electrical equipment inside is completely protected and the life of the product is extended.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1 (e), the housing structure of the electric device according to the present invention is used as a desktop type or wall-mounted type chime adapter. A plurality of switches 2, 2,... For setting the operation of the electric device from outside, and a single switch window 3 surrounding the plurality of switches 2, 2,. And a fitting hole 7 for a stopper for fixing a cover described later (FIG. 1D).

As shown in FIGS. 1 (a) and 1 (b), the housing 4 has a cover 5 which covers one switch window 3 in which a plurality of switches 2, 2,. The cover 5 fixed to the housing 4 is integrally provided with a detachable stopper 6 fixed to the housing 4 in a shape penetrating the fitting hole 8.
As shown in FIG. 1C, the detachable stopper 6 for fixing the cover 5 to the housing 4 is a molded product composed of a knob 61 and a penetrating part 62. And fin 64
When the fin 64 is fitted through the fitting hole 7, the fin 64 is slightly opened in the housing toward the inside of the housing, so that the cover 5 is securely fixed to the housing 4. When the knob 61 is pulled up, the fin 64 narrows and becomes integral with the shaft 63, so that the stopper 6 is easily pulled out of the fitting hole 7, and the cover 5 is integrally formed with the stopper 6. It is easy to remove.

The switch 2 provided in the housing in the housing structure of the electric device according to the present invention is a connecting part between the entrance unit of the intercom apparatus and the plurality of indoor terminal units and the plurality of terminal units. Used for etc. In this case, when a certain switch is turned on, an initial setting is made so that a chime sound is played in response to a call of a slave unit from the corresponding specific terminal.

In the housing structure of the electric device according to the present invention, the inside is protected by the detachable cover 5 fixed by the detachable stopper 6, so that the switch 2 is positioned at the side surface 4s when used on a desk. Even if the switch 2 is located at the position that becomes the upper surface 4u of the housing 4 when used on a wall, entry of dust or the like from the switch window 3 is avoided.

[0012]

As is apparent from the above embodiments, according to the housing structure of the electric device of the present invention, the cover can be easily attached and detached, and the stopper is removed only when the switch is operated. Normally, the cover that covers the switch window is fixed to the housing to prevent dust from entering the inside of the housing from the switch window, so that the electrical equipment inside is completely protected and the life of the product is extended. Will be extended.
