Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a contact block with a novel configuration that is convenient for complex circuit operations.

The purpose of this invention is to provide a central shaft in a multi-stage contact block that is easy to install, and to provide a hollow cylindrical part in the center that penetrates in the direction of the central axis so as to lead out to the indicator lamp of the transformer installed at the lowest stage. To provide a contact block which can be penetrated and easily marked and stamped.

The embodiment shown in the drawings will be described below. Reference numeral 1 is a box body in which a rectangular recess 3 is provided, leaving a hollow cylindrical portion 2 at the center axis, and opening/closing chambers 4, 4 are provided inside one of the two opposing sides. is provided, and lead-out terminal blocks 5, 5 are provided on the other two opposing sides of the protrusion 1.
They are provided on both sides of a.

Further, in the recess 3, insertion holes 7 and 8 for the movable element 6, which move up and down, are formed between the side surface on the side where the opening/closing chamber 4.4 is provided and the side surface on the side where the terminal blocks 5, 5 are provided, respectively. It's open.

The movable element 6 is of the types shown in Fig. 7, and 6a has a shoulder part 6a1 for preventing it from coming off and a supporting step part 6a2 for a support spring 9 (see Fig. 6) below, and 6b has a shoulder part 6a2 for preventing the removal of the movable element 6. The movable contact 10 (see FIG. 5) is supported by a spring in the window hole 6b, and when the movable element 6b is inserted into the through hole 7, the recess between it and the adjacent through hole 8 is Wing piece 6 inserted into 3
b2 is integrally provided, and the upper surface of this wing piece 6b2 serves as a shoulder for preventing slippage.

6c is a combination of the movable elements 6a and 6b, that is, the movable element 6a is attached to one end of the wing piece 6b2 of the movable element 6b, and the movable element 6c is passed through the movable piece part 6c1 of the movable element 6c. The wing piece 6c3 is formed in a substantially rectangular shape so that when inserted into the hole 8, the support piece 6c2 of the movable contact is inserted into the adjacent through hole 7, and straddles the recess 3 between the adjacent through holes 7 and 8. It is designed to be inserted.

6c4 is a step for receiving a spring, and 6c5 is a window hole for supporting a movable contact.

And both rotators 6b and 6c each wing piece 6b2 and 6C3
The lower surface of the recess 3 serves as a receiving part for the support spring 11 (see Fig. 5). Therefore, as shown in Figs. The two cases are one in which the movable member 6c is inserted and the other in which only the mover 6c is inserted as shown in FIGS. 3 and 4.
Seed contact blocks are obtained.

As shown in FIG. 8, the protruding portion 1a has an engaging portion 1 at its upper end.
2a and a connecting tool 12 provided with an ejection locking piece 12b at the lower part.
An insertion hole 13 is provided in which a retaining step portion 13a of the locking piece 12b of the connector 12 is opened at the upper side and an engagement hole 13b of the engaging portion 12a of the connector 12 is opened at the lower side of the through hole 13. and
When a plurality of contact blocks are stacked vertically and connected, the retaining portion 12a of the connector 12 of the lower contact block is inserted into the engagement hole 13b of the insertion hole 13 of the upper contact block, as shown in FIG. They are adapted to be engaged and connected.

A protrusion 2a is provided at the upper end of the opening of the central cylindrical portion 2 at a position opposite to the through holes 7 and 8 to engage the shoulder portion of the movable element 6 and prevent it from being pulled out upward.

FIG. 9 shows a transformer, in which a tube 1 is drawn out from the main body 14.
A lamp 16 is attached above through the main body 14.
The base of the connecting part 12 is attached to both side parts of the engaging part 12.
A is made to protrude.

FIG. 10 shows the relay lead-out tube 15a, and shows the secondary conductor 15.
The upper ends of a1 and 15a2 are inserted and fixed with the insulating protrusion 15a3 interposed between the upper ends thereof.

A recess 15a4 for fitting the insulating protrusion 15a3 is provided inside the lower end of the conductor 15a1, 15a2, and the lead-out tube 15
When the wires 15a1 and 15a2 are connected, the upper end projections of the conductive wires 15al and 15a2 are fitted into the lower end notches 15a12 and 15a22 to establish contact and conduction.

Of course, although omitted in the figure, the connecting part between the lead-out tube 15 and the main body 14 in FIG. 9 is the same as the joint part structure of the relay lead-out tube 15a in FIG.
The relay lead-out tube 15a is inserted and connected.

With the structure described above, when the contact block is attached to a conventionally known operating section such as a push button, it is easy to attach the contact block to a conventionally known operating section such as a push button, for example, by using a contact block that has an engaging hole for the engaging section 12a of the coupling tool 12 below the operating section. It is something that can be installed.

Then, connect the contact block to the sixth
As shown in the figure, when the movable element 6 is used as a pushbutton switch in a multi-tiered structure, only the movable member 6b is used.

At this time, when a pressing force is applied to the push button by the operation part, the mover 6b is pushed down against the support spring, so the mover 6b of the upper contact block pushes down the mover 6b of the lower contact block, so that each support By operating the movable contactor, it can be used as a normal multi-stage pushbutton switch.

Next, in the case of multi-stage stacking, if you want to change the operation of each contact block in the upper and lower stages, movers 6a and 6b are used for the upper contact block, and as shown in Figs. The movable element 6b is inserted into the through hole 7 through the through hole 8 of the lower contact block.
As shown in FIG. 4, only the mover 6c is inserted, stacked, and fixed.

The multi-stage contact block is attached to an operating section having a selector mechanism, for example, and the selector operation rotates the movable element 6 of the upper contact block sequentially in the order of s b y s a y 6 b y 6 a. When the movable element 6b is pushed down in the first operation, the movable contact supported in the window hole 6b1 is operated.

In the next operation, when the movable element 6a is pushed down, the movable piece part 6cl of the movable element 6c of the lower contact block is pushed down, so the support piece part 6c2 is pushed down and the movable contact supported in the window hole 5c operates. .

In the next operation, another movable element 6b operates, and in the next operation, another movable element 6a operates, but this is the same as each operation of the movable elements 6b and 6a described above, and this completes the process. .

In this way, the two upper and lower contact blocks can be made to operate differently, and a selector switch can be easily obtained.

Since the present invention is constructed as described above, when attaching a push button operating section with an illuminated lens to a contact block, the transformer shown in FIG. is inserted upwardly into the central cylindrical portion 2 of the contact block to form the upper end lamp 1.
6 can be brought close to the illumination lens surface, so the switch for display stamping can be easily configured.

Further, when stacking any number of contact blocks of the present invention, a multi-stage contact block with an indicator light can be obtained by using the relay lead-out tube 15a shown in FIG. 10 only in a portion corresponding to the number of stages.

As described above, in this invention, the lead-out tube 15 of the transformer attached to the lower end is inserted into the tube portion 2 provided on the central central axis, and the upper lamp 16 is attached to the upper end of the contact block so as to face the operation section with the illuminating lens. It is easy to display and stamp the display, and it is extremely effective when used in operation circuits that require a complicated circuit configuration.

Note that the central tube portion 2 is not limited to a cylindrical shape, and may of course be square or other shape.
