Description

[Detailed Description of the Invention] This invention relates to a composite relay device that can send out not only contact output but also semiconductor switching element output.

As is well known, electromagnetic relays are inferior to non-contact relays, which are output from semiconductor switching elements, in terms of contact life and reliability, because they have contact output. Therefore, in relay devices that open and close various loads such as large current loads, small current loads, or loads with different switching frequencies, non-contact relays are used as appropriate to produce long-life and highly reliable relay devices. There is. However, contactless relays and electromagnetic relays often have different terminal structures, which requires time and effort to manufacture relay devices, and even if they have the same terminal structure, it is necessary to replace the contactless relay and electromagnetic relay due to changes in specifications. In some cases, parts have to be procured again.

This idea was proposed in view of the above points, and has both contact output and non-contact output, and by selecting and using both outputs as appropriate according to the load specifications, long life and reliability can be achieved. The purpose of this invention is to provide a composite relay device that makes it possible to manufacture a high quality relay device.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a circuit diagram of a composite relay device according to this invention.

In the figure, a coil C forming an electromagnetic relay section R and an input section of a photocoupler P forming a non-contact relay section S are connected in parallel to input terminals 1 and 2.
When input signals are applied to input terminals 1 and 2, contact T is activated in electromagnetic relay section R, and contact output signals are sent from normally closed contact terminal 3, normally closed contact terminal 4, and common contact terminal 5. In the non-contact relay section S, the output signal of the photocoupler P is amplified by an amplifier circuit A consisting of a semiconductor element, etc., and is sent to a non-contact output terminal 6,
Sent from 7.

Next, a schematic structure (internal structure omitted) of a composite relay device having the above-described circuit configuration will be shown.

In the composite relay device shown in FIG. 2, an electromagnetic relay section R consisting of a coil C, a contact T, etc. is built into the lower half 10a of the case 8, and an upper half 10a of the case 8 is built-in.
A non-contact relay section S formed by mounting a semiconductor element such as a photocoupler P on a printed circuit board is built in b. Input terminals 1 and 2 and contact output terminal 3 are connected to the base 9 inserted into the bottom surface of the case 8.
4 and 5 are arranged, and non-contact output terminals 6 and 7 are arranged on the upper surface of the case. The terminal group protruding from the base 9 has a terminal structure that can be inserted and connected to a relay socket (not shown), while the non-contact output terminal 6,
Reference numeral 7 is formed with a screw terminal, Faston terminal, or the like to facilitate wiring connection.

In addition, the composite relay device shown in FIG.
The electromagnetic relay part R is on the left side 11a, and the right side 11b is
Case 8 has a non-contact relay section S installed in
A terminal group including input terminals 1, 2, contact output terminals 3, 4, 5, and non-contact output terminals 6, 7 are arranged on the base 9 on the lower surface so that they can be inserted into and connected to a relay socket (not shown).

Furthermore, FIG. 4 shows a composite relay device in which the non-contact relay section S is formed as a separate block from the electromagnetic relay section R.
However, each case 8b has a built-in non-contact relay section S, and a plug terminal 1 formed on the upper surface of the case 8a and connected to each of the input terminals 1 and 2.
Receptacle terminals 1a, 2a on the bottom surface of case 8b on a, 2a
By inserting and connecting the connecting terminals 1b and 2b, which are input terminals to the non-contact relay part S protrudingly provided in a position facing the If it is formed so that it can be transmitted to the section S, and if it is made into a detachable block like this, it is possible to use only the electromagnetic relay section R when the non-contact relay section S is not required. It is also possible to form a block including various functions such as (1) and attach it to the electromagnetic relay section R.

As detailed above, this invention is configured by adding the function of a non-contact relay to a conventional electromagnetic relay, so the output specifications can be selected and used according to the load specifications, and the relay device can be manufactured easily. This has practical effects in terms of parts procurement and shortening of manufacturing period even if specifications are changed midway through the process.
