Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a holding device for a switch used in a heating device or the like to cut off electricity or issue a control signal by opening and closing a door of a heating chamber.

In conventional high-frequency heating devices such as microwave ovens, three switches are generally used to extract electrical signals from opening and closing of a door.

In FIG. 6, three switches 2, 3.4 are attached to a switch holder 1, and two swingable keys are provided to protrude from the back side of a door 5 that can be opened and closed. 6
, the switches 2, 3.4 were actuated via the levers 8, 9 and 10.

Note that switch 2 and switch 4 are equivalent and connected in parallel, and when door 6 is opened, this switch is turned on at the same time.
ff, and the circuit can be cut off. switch 3
The operation of the switch is set to be time-shifted from that of the switches 2 and 4. When the key 7 is inserted, the lever 9 first operates the switch 3, and then the tip of the key 7 operates the switch via the lever 10. Operate 4. When opening the door, the switches operate in the reverse order as above.

In recent years, in the above configuration, devices have been added with an electronic control function using a microcomputer, etc., and in this case, a separate switch is required to send a signal to the electronic side leg circuit including the microcomputer, and the timing of its operation is This is the same as the switches 2 to 4, which are turned on and off at the same time by opening and closing switch 5. For this reason, since there are only four switches, the method shown in FIGS. 7 and 8 is used as the mounting method.

That is, a signal switch 11 for an electronic control circuit of the same shape is arranged at the position where the switch 4 is attached and held, and the two switches are brought into close contact with each other to form a holding part 12 with a claw.
13, and the switches 4 and 1
Through holes 4a, 4b provided in 1, and 11a, 1
The bottle 14.15 to be inserted into the holding part 12.1
Similarly to 3, when the switch 4 is integrally formed with the holder 1 and the operating position of the switch 4 is only the holder that presses the outer shape, it is not only held more securely and firmly, but also serves as a guide pin during insertion. be able to.

Problems to be Solved by the Invention With the above configuration, components such as the switch holder cannot be shared between cases where an electronic circuit is not used and cases where an electronic circuit is used. In other words, a holder with dimensions for holding two switches only requires one switch when no electronic circuit is used, and the switch cannot be held securely, so it cannot be turned on or off.
Off'f operation becomes extremely unstable.

To compensate for this drawback, if you only need one switch, insert a separate spacer with the same shape and dimensions as the switch to maintain the same condition as if two switches were installed. I was using it.

This requires an extra part called a spacer, and the assembly work increases accordingly, resulting in an increase in cost.

If the structure of the holder is manufactured differently based on each application, the above disadvantages will be eliminated, but the cost of manufacturing parts such as molding molds will increase, and furthermore, the troublesome work in terms of service management will increase. There was a problem.

Means for Solving the Problems The present invention solves the above-mentioned problems, and includes a plurality of holding portions having claws for holding a plurality of rectangular parallelepiped switches having the same outer shape in an adjacent state, and a plurality of holding portions provided on the switch. and a plurality of bottles to be inserted into and positioned through the through-holes arranged in the switch are integrally formed with a surface that contacts the switch wall surface as a base, and the bins hold a smaller number of switches than the plurality of switches that the holding part can hold. The pin is provided at a height that allows the bottle to be bent easily by the inner wall of the through hole of the switch when a plurality of switches are inserted.

Effect According to the above configuration, when installing a small number of switches, a plurality of bottles can be placed facing the switch through-hole, inserted as a guide, and pressed against the base of the holder, and the holes provided in the bottle outer shape can be inserted. The claw passes through the switch through hole and is caught on the outside, preventing it from coming off.

When a plurality of switches are inserted, the claws provided on the bottle are pushed by the inner wall of the through hole of the switch and are bent, and the plurality of switches are tightly fixed by the shape retaining claws.

With this configuration, the holder can be used in common even if the number of switches to be installed is different, and when removing multiple switches, if you remove them while keeping them in close contact with each other, the bottle's claws will catch on them, making it easy to remove them. There is an effect that it can be done.

Example Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, the holder 16 has a bottom surface 18 that comes into contact with the wall surface of the microswitch 17, from which two round bottles 19, 20 and two holders with claws extending along the outer shape are attached. 21 and 27 are integrally formed. The bottle 19.20 has a rectangular parallelepiped shape, and when the microswitch 17 (indicated by a two-dot chain line in FIG. 1) having two through holes 23.24 comes into close contact with the bottom surface 18 of the holder, It has claws 25 and 26 that hook onto the outer wall on the opposite side.

The through holes 23, 24 of the microswitch 17 are arranged diagonally, so that the pins 19, 20 are guided during insertion and are held securely. Note that 27 is the actuator button of the switch, and 28 is the [terminal].

Figure 3 shows the case where the second switch 29 is installed,
The claws of the bottles 19 and 20 are connected to the through holes 3 of the second switch 29.
Pushed by the inner wall of the bottle 19, the claw tip 25,26 flexes to an outer circumferential dimension that is approximately the same as the outer shape of the bottle 19,20, and the switches 17 and 29 are held in close contact. As a result, one type of holder 16 can be used for both one and two switches. Figure 4 shows the second embodiment.
Vi/30.
31 and a first switch 17 on the outer circumference of this bottle.
A first claw 32 is provided at a height that can hold the second switch 29, and a second claw 33 is provided at a height that can hold the second switch 29. It is constructed so that it can be easily bent by the inner wall of the hole.

Fig. S shows a third embodiment in which two switches 1 and 7.29 are held in close contact with each other, and a second switch is placed in a position where the first switch 17 can be held between the claws 34 and 35. switch 2
The claws 36 and 37 which are easily bent by the outer wall of 9 are provided, and the structure is such that the same effect as described above can be obtained.

Effect of the invention According to the present invention, the following effects can be obtained.

(1) Even if the number of switches provided is different, the holder can be reliably attached and held depending on the application, and when a plurality of switches are attached, the operating timing of the switches can be made the same.

(2) Parts of the holding body can be shared, and even if there are few switches, no extra spacers are required, leading to cost reduction.

(3) Multiple switches in close contact! By removing it, you can work without any trouble without getting caught by the claws that hold the switch on the holder side.
