Description

[Detailed Description of the Invention] The present invention relates to a collective relay that includes a plurality of relay units.

Conventionally, when multiple relays were required, the desired number of relays was simply mounted on a printed board, an input signal circuit was printed as needed on the printed board, and the input signal circuit and the input section of the relay were connected. were configured by electrically connecting them.

However, with this type of device, manufacturing is complicated because the input signal circuit must be printed on the printed circuit board in advance, and if the circuit needs to be modified, a new printed board must be prepared. First, there was a problem that the application was narrow and lacked versatility.

The present invention improves the above-mentioned drawbacks, and the terminal section for the human signal circuit is provided in multiple stages on a base made of a printed board, and each coil terminal of a plurality of relay units attached to this base is connected. It is an object of the present invention to provide a collective relay that can easily form a circuit by inserting a communication pin into the terminal portion of the relay and is rich in diversity.

The present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention.

In these figures, 1 is the casing of the collective relay,
This casing 1 has a base 2 made of a plate-shaped printed board.
It consists of a box-shaped cover 3 which is attached to a part of the base 2.

On one surface of the base 2 to which the cover 3 is attached, there are a plurality of terminal portions 4 forming input circuits extending parallel to each other and spaced apart from both sides of the cover 3 toward the end of the base 2. , 4' are provided.

Near the tips of these terminal parts 4, 4' and the terminal parts 4,
4' is provided with a through hole 5 that communicates from one side of the base 2 to the other side.
is drilled.

Further, near the side edge of the other surface of the base 2, the through hole 5 on one surface corresponds to the lower side of the terminal portions 4, 4' and is perpendicular to the terminal portions 4, 4'. Conductive parts 6, 6 for a communication circuit extending along the side edges of the base 2 are printed on the base 2.

In this case, it is also possible to insert a conductive material into the base 2 instead of the conductive portion 6 printed on the back surface of the base 2.

Reference numeral 7 denotes a cylindrical communication pin made of a conductive material.

Therefore, this communication pin 7 can be connected to each terminal portion 4 as appropriate.
By inserting it into the through hole 5 of the base 2, the terminal portion 4 provided on each surface of the base 2 and the conductive portion 6 are connected by the communication pin 7, and the terminal portions 4, which are spaced apart from each other, are also communicated with each other. By inserting the pin 7, electrical connection is established via the conductive portion 6.

3 and 4 show a relay unit 8 applied to the present invention.

That is, the relay unit 8 mounted on the base 2 has a hollow coil frame 9, and the coil frame 9 has hollow enlarged portions 10° and 11 formed at both ends, and a coil 12 is wound around the coil frame 9.

A coil terminal 13 is simultaneously molded on each of the enlarged portions 10 and 11, and a common terminal 14 is press-fitted and fixed to one of the enlarged portions 11.

The common terminal 14 is formed in a U-shape, and the free end is connected to the coil frame 9.
A fixing part 14 a to which the proximal end of a lead 15 passing through the inside is fixed approximately at the center, and a leg part 1 extending to both sides of the enlarged part 11 .
4b.

On the other hand, a horizontally cut engagement groove 16.17 is formed in the other enlarged portion 10, into which a magnetic pole body 18.19 is inserted and fixed.

Terminal portions 18 a and 19 a extending to both sides of the enlarged portion 10 are extended to the magnetic pole bodies 18 and 19, and fixed contacts 18 b and 19 b facing each other with a slight contact gap 20 are firmly connected, respectively. There is.

A lead 15 fixed to the common terminal 14 is provided in the contact gap 20.
The free end of is extended.

Further, a permanent magnet 21 is arranged between the magnetic pole bodies 18 and 19.

Coil 1 of relay unit 8 configured in this way
2, the magnetic force of the permanent magnet 21 is canceled and the lead 15 is attracted from one fixed contact 19b to the opposite fixed contact 18b, thereby switching the contacts.

When assembling, each terminal is inserted into a hole (not shown) for the contact terminal 18a, 19a common terminal 14 of the relay unit 8, which is appropriately drilled in the bottom of the base 2, so that multiple independent relay functions can be performed. A group of relays is mounted on the base 2.

Then, a collective relay body is completed by mounting a cover 3 on the base 2 so as to house a group of these relays inside, but in this case, the + side terminal of the coil terminal 13 of each relay unit 8 is Each coil terminal 13 is connected within the cover 3 to a corresponding terminal portion 4 provided on one side of the base 2, and one terminal of the coil terminal 13 is connected to a terminal portion 4' provided on the other side.

As an electrical connection means between the coil terminal 13 and the terminal parts 4, 4', a conductive part extending from the coil terminal to each terminal part 4, 4' may be printed on the base 2.

Moreover, it is also possible to insert a metal fitting made of a conductive material into the base 2 instead of the plug.

When used, the input signal circuit consisting of the terminal section 4, the conductive section 6, etc. is short-circuited by appropriately inserting the communication pin 7 into the through hole 5 provided in the base 2, and performing a soldering process, for example. This makes it possible to easily configure a desired circuit, and to operate a desired plurality of relay units 8 using the same signal.

FIG. 5 shows another embodiment of the present invention, in which the conductive part 6 shown in FIGS. 1 and 2 is removed,
This embodiment differs from the previous embodiment in that the communication pin 7a is formed in a U-shape.

In use, there should be a through hole (
A desired input circuit can be formed by inserting the communication pin 7a through L5, 5 so as to bridge them.

In this case, the communicating pins 7a, 7 have different lengths depending on the purpose.
If you prepare multiple a', you can connect terminal parts 4, 4 with different distances.
When short-circuiting between them, it is preferable to select a communication pin 7a' having an appropriate length because the short-circuit can be easily achieved.

Note that the other configurations and operations are substantially the same as those of the previous embodiment, so detailed explanations will be omitted.

As described above, according to the present invention, each relay unit can be operated with the same signal by simply inserting a connecting pin for shorting into the terminal part during use, and a desired circuit can be easily obtained. There is no need to print a manual signal circuit each time the circuit is changed as in the example above, and the circuit can be changed easily.

In addition, since the base has a printed board configuration, electronic components that are used simultaneously in combination with the collective relay can be loaded in the entire space of the same printed board (base), and the circuits can also be printed on the base in advance. The base is highly versatile and can be used not only as a collective relay but also as a mounting board for electronic components, which has the advantage of saving space, increasing packaging density, and reducing parts.
