Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a configuration for connecting an operating mechanism of, for example, a pushbutton switch to one or more switch mechanisms.

When the number of contact points of a push button switch is increased according to demand, the required number of switch mechanisms are stacked together and integrated with a connecting bolt, and the structure is such that the switch mechanism can be operated with a single push button.

FIG. 1 is a front view showing an example of a conventional illuminated pushbutton switch.

In the figure, 1 is an operating mechanism case, 2 is a push button that also serves as a light plate, 3 and 4 are lamp terminal plates, and 5 is a switch mechanism connected to the operating mechanism by a bolt 6.

When increasing the number of switch mechanisms 5' and 5'', etc., replace and connect bolts 6' and 6'' with lengths corresponding to the increased length.

In this way, in conventional push button switches, connecting bolts of various sizes must be prepared in order to connect various switch mechanisms with different numbers of layers.

Further, in the case of an illuminated pushbutton switch, when a unit in which a large number of switch mechanisms are stacked is mounted closely on a panel, wiring is difficult because the lamp terminals 3 and 4 are located deep inside the switch mechanism.

The present invention was developed in order to eliminate the above-mentioned drawbacks, and includes a connecting plate that has a shape in which a number of unit connecting fittings are connected, in which the head and the body are arranged facing each other through the neck, and a connecting plate that has elasticity. It is made of a member and has protrusions cut and raised on the outside and inside.For example, it is wide enough to fit the terminal plate of the operating mechanism and the head and neck of the connecting plate provided opposite the side of the base of the operating mechanism. and a second groove provided on the inner wall of the groove into which the terminal plate can be inserted in the longitudinal direction, and the connecting plate is inserted into the first groove. After fitting, by inserting the terminal board into the second groove, the outer protrusion of the terminal board locks with the case of the operating mechanism, and the inner protrusion prevents the terminal board from being removed. By elastically locking and causing the remaining part of the connecting plate to protrude to the outside, and inserting the protruding part of the connecting plate into a rectangular through hole bored in a switch mechanism disposed opposite to the base. The required number of switch mechanisms are connected in a sash-like manner, the connecting plate protruding from the last switch mechanism is cut to a length that only the body of the plate protrudes, and this body is twisted to connect the operating mechanism and the switch mechanism. are fixed to each other.

When applying this to an illuminated pushbutton switch, the terminal plate laid on the operating unit base and the connecting plate using a conductive member are inserted into the second groove of the operating mechanism base so that the protrusions of the terminal plate have elasticity. It is convenient for wiring to make electrical contact using the terminal board and pull the terminal board out to the outermost part of the switch mechanism.

Embodiments of the present invention will be described in detail below with reference to FIGS. 2 to 8.

In FIGS. 2 and 3, 1 is a main body case having a window 1a, 2 is an illumination plate having a protrusion 2a, and its leg 2b also serves as a push rod of a switch mechanism connected to the lower part.

The protrusion 2a engages with the frame of the window 1a and prevents the back spring 7 from removing it.

The bottom of the case 1 takes the form of a base 8, supports a lamp holder 10 that holds a lamp 9, and houses terminal plates 3 and 4 that form an electric circuit, a conductive spring 11, and a connecting fitting that connects to the switch mechanism 5. is configured to do so.

The terminal plates 3 and 4 are elastic members, and as is clear from FIG. 4, which shows the common part of both terminal plates, the outer protrusion 3a
Or 4a, cut and raise the inner protrusion 3b or 4b, and hole 3C
Or wear 4C.

As shown in the perspective view of FIG. 5, the mounting portion of the terminal plates 3 and 4 of the base 8 has a first groove 8a on the side surface, and the first groove has a portion 8b slightly wider than this groove and a step portion 8C. Equipped with
Furthermore, a second groove 8d for laying the terminal plates 3 and 4 is bored in its inner wall.

The first grooves are provided opposite to each other on both sides of the base 8.

The connecting fitting 12 is made of a band-shaped electric conductor, and as shown in FIG. 6, a head portion 12a (length C) and a body portion 12C (length E) are arranged opposite to each other with a neck portion 12b (length D) interposed therebetween. It has a shape in which many unit connecting fittings are connected, and the head 1
2a and the neck part 12b are aligned with the jaw part 12d, and the body part 12C512C'... has a hole 12e.

12e'... is the hole.

As shown in the perspective view of FIG. 7, the connecting portion of the switch mechanism 5 has a rectangular hole 5a through which the connecting fitting 12 is fitted, and an insertion hole 5b for the terminal plates 3 and 4.

The method of connecting the switch mechanism 5 and the base 8 of the operating mechanism is to first insert the head 12a of the connecting fitting 12 into the first groove 8a of the base 8.
The neck portion 12b is fitted into the first groove 8a of the wide portion 8b, and the jaw portion 12d of the connecting fitting 12 is supported by the stepped portion 8C of the base 8.

At this point, the terminal plate 3 or 4 is inserted into the second groove 8d from above until the outer protrusion 3a or 4a of the terminal plate 3 or 4 engages with the bottom edge of the case 1.

At this time, the inner protrusion 3b or 4b of the terminal plate 3 or 4 comes into electrical contact with the connecting fitting 12 because it has spring properties.

Further, the connecting fitting 12 is not obstructed by the terminal plate 3 or 4 and does not protrude outward.

Next, the connecting fitting 12 is inserted into the hole 5a of the switch mechanism.

The length of the connecting fitting 12 is determined by the relationship A<D, A+B≦D+E+C+D, where A is the height of the groove 8a of the operating mechanism base 8 and B is the height of the switch mechanism.

It is also possible to connect a large number of switch mechanisms 5 in a row, and when connecting one switch, cut the connecting fitting 12 at X in Fig. 6 and twist the body 12C' by 90 degrees. The switch mechanism and the base 8 of the operating mechanism are connected with the side lid.

To connect two switch mechanisms, as shown in FIG. 8, cut the connecting fitting 12 at Y in FIG. 6, and twist the body 12C'' by 90 degrees to complete the process.

The hole 12e'' is used when connecting an external conductor.

In the following, when connecting a large number of switch mechanisms, insert the connecting fitting 12 into the through groove 5a of each switch mechanism 5, connect the switch mechanisms 5 in a bow shape, and the body of the connecting fitting protrudes from the last switch mechanism. Cut it leaving 12 C and twist this body 12 C by 90° to complete.

As explained above, according to the present invention, a pushbutton switch, an operating mechanism, and one or more switch mechanisms are connected using a connecting metal fitting, and the connecting metal fitting is cut into arbitrary dimensions depending on the number of switch mechanisms to be connected. Since it is possible to use multiple types of connectors, the number of parts can be reduced by stocking only one type of connecting metal fittings, and assembly is also simple.

Further, when this connecting metal fitting is used for an illuminated pushbutton switch, it can be electrically connected to the terminal plate of the operating mechanism and protruded from the bottom of the last connected switch mechanism, which is convenient for wiring.
