Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric device suitable for application to an air conditioner of an air conditioning control device, and more particularly to an electric device which can be pulled out inside a wall or a control panel.

[0002]

2. Description of the Related Art In an air-conditioning control device, operation / stop switching, setting and changing of operating conditions such as temperature and air flow are performed by an air-conditioning setting device mounted on a wall or the like.
Therefore, the air-conditioning setting device includes a display device for displaying a setting state, for example, a liquid crystal display device (LCD), a push button switch, and the like, and is connected to the air-conditioning control device by a cable for signal transmission. Further, a recent setting device of this type includes an interface that enables connection of an external device such as a personal computer (PC) or a memory card at the time of setting and adjusting the temperature and the air volume. ing.

[0003] As such an air conditioner setting device, one disclosed in Japanese Patent Application Laid-Open No. 10-322038 is known. As shown in FIG. 16, this air-conditioning setter covers a front opening 4 of a case body 3 embedded and installed in a control panel (or wall surface) 2 with a front cover 5. A box-shaped frame 6, which is housed so as to be able to be pulled out, is mounted in the frame 3, and electric components that can be accessed only at the time of maintenance, such as a connector, an adjustment volume / switch, a battery holder,
The memory card 7 incorporates a card connector or the like to be mounted through a slot 8, and allows an operator to access the electrical components by pulling out the frame 6 together with the front cover 5 from the case body 3 during maintenance. is there.

[0004] The memory card 7 stores the values of various parameters that have been set and data relating to the operation history.
The card connector is accessed by a maintenance worker only during maintenance such as replacement of the memory card 7. Therefore, the card insertion hole of the card connector faces the slot 8. The slot 8 is formed on one side surface of the frame 6 and is normally hidden inside the case body 3 so as to be invisible from the front side of the air conditioner 1. The memory card 7 can be mounted on the card connector only when the memory card 7 is pulled out from the front opening 4 of the case body 3. As a card connector of the memory card 7, one disclosed in Japanese Patent Application Laid-Open No. 10-27649 is known.

The reason why the card connector is structured to be accessible only at the time of maintenance is as follows. Since the card connector is accessed by the maintenance worker only during maintenance, it is not necessary to provide the card connector on the front of the device. If the card connector is provided so as to be exposed on the front side of the device, dust, water, and the like may enter the device from there, which may cause a failure of the device. If the slot 8 is formed on the front face of the front cover 5 and the card connector is attached to the back face of the front cover correspondingly, the insertion direction of the memory card 7 becomes the depth direction of the device, and the depth dimension of the device increases. I do. As a result, the volume of the device increases, and a large control panel is required when incorporating the device into the control panel. Further, it cannot meet the demand for miniaturization.

[0006]

The conventional air-conditioning setting device 1 disclosed in the above publication has the following problems. That is, since the slot 8 for inserting the memory card is provided on the side surface of the frame 6,
Even if the frame 6 is pulled out from the case body 3 together with the front cover 5, when inserting the memory card 7 into the slot 8, the user must look into the side of the frame 6 on the slot 8 side. Due to the location of the container, if there is not enough space around the side surface on the slot 8 side to visually recognize the slot 8, the position of the slot 8 cannot be determined and the user has to work by groping. Is bad and takes time. Further, if the user tries to insert the memory card forcibly, the memory card 7 itself or the card connector may be damaged.

The above problem can be solved by forming the slot 8 on the front side of the front cover 5, but in this case, the longitudinal direction (insertion direction) of the memory card 7 becomes the depth direction of the setting device, and A new problem arises in that the volume of the control panel containing the setting device and the setting device increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. An object of the present invention is to perform a memory card insertion / removal operation in front of a device without increasing the depth of the device. It is an object of the present invention to provide an electric device which can be improved in workability at the time of maintenance.

[0009]

According to a first aspect of the present invention, there is provided an electric apparatus having a card connector which is installed in a control panel, a wall, or the like and in which a memory card is mounted. The connector is incorporated in the electric device so that its longitudinal direction is orthogonal to the depth direction of the electric device, and is configured to be able to be pulled out to the front of the electric device.

In a second aspect of the present invention, in the first aspect, a case body embedded and installed in a control panel, a wall, or the like, a front cover covering a front opening of the case body, and the case attached to the front cover. A frame housed in the main body so as to be able to be pulled out, and a drawer mechanism including a connector holding member to which the card connector is attached so as to be able to be drawn out to the side of the frame in the frame,
The card connector is attached to the connector holding member so as to be rotatable in the front-rear direction.

According to a third aspect of the present invention, in the first aspect, there is provided a case body embedded and installed in a control panel, a wall, or the like, and a front cover for covering a front opening of the case body. An outlet for a card connector is provided on the front side, and the card connector is provided on the back side so as to be able to be pulled out from the outlet.

According to a fourth aspect of the present invention, in the first aspect, a case body embedded and installed in a control panel, a wall, or the like, a front cover for covering a front opening of the case body, and a rear side of the front cover. And a frame housed in the case body so as to be able to be pulled out. The frame is connected to a first frame attached to the front cover, and a first frame is rotatably connected to one end of the first frame. 2
A frame, wherein the card connector is incorporated inside the first frame, and a slot for a memory card is formed on a side surface corresponding to the card connector.

According to a fifth aspect of the present invention, in the first aspect, a case body embedded and installed in a control panel, a wall, or the like, and an openable and closable one end rotatably supported by an opening on the front surface of the case body. A front cover, and a frame attached to the back side of the front cover, wherein the card connector is incorporated in the frame, and a slot for a memory card is formed on a side surface corresponding to the card connector. is there.

In the present invention, since the card connector is pulled out to the front of the electric equipment, the operation of inserting and removing the memory card can be performed from the front. Since the card connector is incorporated so that its longitudinal direction is orthogonal to the depth direction of the electric device, it is possible to suppress an increase in the depth dimension of the electric device.
