Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card switch device.

0002

[Prior Art] A card switch device is used in hotels, etc. for the purpose of turning on the lights in the room where the device is installed, detecting occupancy, etc. by inserting a card the size of a business card and driving the switch section. provided in the room.

0003

[Problems to be Solved by the Invention] However, in the conventional card switch device, the mounting pitch of the main body of the device corresponds to the mounting pitch (83.5 mm) of the outlet box corresponding to the three module dimensions of a general wiring device. Therefore, there was a problem that the size of the device body was large compared to the size of the business card-sized card used, and the external design was poor.

[0004] Furthermore, when attaching to the outlet box, since a mounting frame is required, there is a problem in that the number of parts increases. The present invention has been made in view of the above-mentioned problems, and its purpose is to:
To provide a card switch device which allows the external design of the device main body to match the size of a card by reducing the mounting pitch of the device main body, and furthermore has a small number of parts.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the invention as claimed in claim 1 provides an outlet box that is formed in a size corresponding to an outlet box having a mounting pitch close to the length dimension in the insertion direction of the card to be used. A cover with a rear opening that allows
The main body of the device is composed of a body that is removably fitted into the rear opening of the cover, and a switch section driven by a card inserted through the card slot opened in the cover is housed in the main body of the device, and an outlet is provided in the body. A mounting hole is provided through which a box screw is inserted to be screwed into the mounting screw hole of the box.

According to the second aspect of the invention, a driver insertion groove is provided on the periphery of the body, and a notch is provided on the periphery of the rear opening of the cover so that the opening of the driver insertion groove faces the outside when the cover and the body are fitted. It has holes.

[0007]

[Operation] Since the cover is formed in a size that corresponds to the outlet box that has a mounting pitch close to the length dimension in the insertion direction of the card to be used, the size of the main body of the device can be brought closer to the size of the card to be used. It is possible to create a cohesive external design that matches the size of the card.

[0008] Furthermore, by providing a mounting hole through the body for inserting a box screw that is screwed into the mounting screw hole of the outlet box, the body also serves as the mounting frame, so a separate mounting frame must be used. The main body of the device can be attached to the outlet box. A driver insertion groove is provided on the periphery of the body, and a notch hole is provided on the periphery of the back opening of the cover so that the opening of the driver insertion groove faces the outside when the cover and body are fitted. By inserting the screwdriver into the screwdriver insertion groove and using the screwdriver as a lever to pry open the cover, the fitted cover and body can be easily separated.

[0009]

[Examples] The present invention will be explained below with reference to Examples. 1 to 4 are drawings showing one embodiment, and the illustrated device main body 1 has a mounting pitch (60 mm) close to the length dimension in the insertion direction of a business card-sized card (not shown) to be used. Medium-sized square outlet box to attach the mounting frame
It is composed of a cover 2 made of a synthetic resin molded product with an outer shape formed to dimensions corresponding to the dimensions and an opening at the back, and a body 5 made of a synthetic resin molded product that is removably fitted into the back opening of the cover 2. be done.

[0010] The cover 2 has an upper cover 4 provided with a card insertion slot 3 fitted into a fitting opening 9 opened on the upper surface and fixed by ultrasonic heat bonding. In addition, the cover 2 has an inverted triangular hole 6 in the center of the upper front, and an inverted triangular protrusion 7a provided on the light-transmitting synthetic resin cover 7 arranged on the back side of the hole 6. When fitted, the protrusion 7a is exposed to the outside from the front of the cover 2. This protrusion 7a constitutes an illuminated display section for position display. The cover 2 further has a body 5 on the inner surface of both sides.
A locking recess 1 for locking a locking protrusion 10 provided on both outer surfaces of the
1 is provided.

The body 5 has the locking protrusions 1 on both outer surfaces.
0, and a recessed part 12 with an open front side is provided in the center, and a printed circuit board 14 of the switch part 13 is housed in this recessed part 12 by being placed on the rib, and is fixed with screws 15. . Also, in the center of the upper and lower sides of the body 5 are mounting holes 16 corresponding to the mounting pitch of the outlet box
are provided through the mounting holes 16, respectively, and locking holes 17 are provided on both sides of the mounting holes 16 for clipping fittings (not shown) used when mounting the device main body 1 to a wall panel.

The switch unit 13 is composed of the printed circuit board 14, two microswitches SW1 and SW2 attached to the printed circuit board 14, a neon lamp L, and a current limiting resistor R. As shown in FIG. Terminals 20a and 20b are connected to the common terminals of the switches SW1 and SW2, respectively, terminal 20c is connected to the normally closed contact of the microswitch SW1 via the neon lamp L and the current limiting resistor R, and the normally closed terminal of the microswitch SW1 is Terminal 20d connected to open contact and micro switch SW2
An outlet 1 is provided through which the six lead wires 22 connected to the normally open and normally closed contacts of the terminals 20e and 20f are passed through from the inner surface of the recess 12 of the body 5 to the back surface of the body 5.
8 to the back of the body 5.

When the main body 1 of the device is to be attached to the outlet box 19 is screwed into the mounting screw hole 21 of the outlet box X to attach the body 5 to the opening of the outlet box X.

[0014] Also, a lead wire 2 led out to the back side of the body 5
2 to the wiring previously wired inside the outlet box X. After that, the body 5 is fitted into the cover 2 by pushing the front side of the body 5 into the inside through the rear opening. In this case, the locking protrusions 10 on both outer surfaces of the body 5 engage into the engaging recesses 11 formed on both inner surfaces of the cover 2, and the cover 2 is fixed to the body 1, forming the main body 1 of the device.

The microswitches SW1 and SW2 of the switch section 13 are attached to the body 5 by this fitting.
The tips of the actuators 231 and 232 face the card insertion slot 3 of the upper cover 4, which is fitted into the fitting opening 9 on the upper surface of the cover 2, and the neon lamp L faces the protrusion 7a of the cover 7. You will be facing the part. When removing the cover 2 with the body 5 fitted, insert the tip of a screwdriver into the driver insertion groove 25 provided on the bottom surface of the body 5 through the notch hole 24 provided on the bottom surface of the cover 7, and use the screwdriver as a lever. By pushing out the cover 2 in the front direction, the locking projection 10 and the engagement recess 11 are disengaged, and the cover 7 and the body 5 can be easily separated.

Next, the operation of the circuit shown in FIG. 4 will be explained. When the card is not inserted into the device main body 1, each of the microswitches SW1 and SW2 is connected to the normally closed contact side as shown in the figure, and the lighting loads 261 and 262 are both turned off and the light is turned off. At this time neon lamp L
is connected to the power source AC via the current limiting resistor R and lights up, illuminating the protrusion 7a of the cover 7 from behind to display the installation location of the main body 1 of the apparatus.

Next, when the card is inserted into the device main body 1 through the card insertion slot 3, each microswitch SW1, S
The actuators 311 and 312 of W2 are pushed and driven by the card to each micro switch SW1 and SW.
2 switches to the normally open contact side, and each lighting load 261,
Connect the 262 to the AC power source and turn it on. Further, the energizing path of the neon lamp L is cut off and the light goes out.
