Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a socket type relay, and more particularly to a relay with a socket type switch in which a relay switch and a mechanical switch are integrated.

[Related Art] A conventionally used sequence circuit includes a plurality of timers, switches, relays, and the like.
In such a circuit, a mechanical switch, a relay, and the like are provided on a base. The relay is generally of a socket type so as to be detachable from the base. The mechanical switch is provided when a manual contact is required in the circuit, and is provided on a base like a relay.

[Problems to be Solved by the Invention] By the way, the above-mentioned socket type relay can only output a contact by exciting a coil included therein. Therefore, when a manual mechanical switch is required in the same circuit for the above-described sequence circuit, a mechanical switch must be provided separately from the socket type relay. Further, when this mechanical switch is provided on a board, it is not provided in the circuit of the relay, but is provided on the same board. Therefore, the wiring between the relay and the mechanical switch and the base is restricted. Further, due to this restriction, there also arises a problem such as an increase in cost in manufacturing the substrate.

Further, when the mechanical switch is provided in the relay circuit, the appearance of the relay and the mechanical switch cannot be balanced, and there is a problem that installation is difficult from the viewpoint of aesthetics and structure.

The present invention has been made in view of the above points,
An object of the present invention is to provide a socket-type switch-equipped relay that can be easily manufactured from the viewpoint of aesthetics and structure without increasing the cost due to restriction between the mechanical switch and the base even when the mechanical switch is provided in the relay circuit.

[Means for Solving the Problems] That is, according to the present invention, a coil means to be excited,
At least one first opening / closing means for opening and closing the contacts in relation to the excitation of the coil means; at least one second opening / closing means for opening and closing the contacts without being associated with the excitation of the coil means; Means and the first and second opening / closing means are integrally provided, and the apparatus further comprises a housing means having outside the coil means and terminals corresponding to the contacts of the first and second opening / closing means. It is characterized by the following.

[Action] A relay with a socket-type switch according to the present invention includes a coil to be excited and a relay switch that opens and closes a contact in connection with excitation of the coil in a case. A mechanical switch is provided in this case, and the switch can be opened and closed regardless of the excitation of the coil. Terminals corresponding to the contacts of these switches are provided outside the case, and by fitting these terminals into a base or the like, the switches can be detachably attached without any restriction between the bases.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are an internal wiring diagram and an external perspective view of a socket-type switch-equipped relay according to the present invention. In FIG. 1, the relay with socket type switch 10 is
It has eleven terminals 11. These terminals 11 are 11a, 11
b, 11c, 11d, 11e, 11f, 11g, 11h, 11i, 11j, and 11k, and the connections described below are respectively made.

That is, the terminal 11a is connected to a common terminal of the relay switch RS of the socket-type switch-equipped relay 10, and the terminals 11d and 11e are connected to a make contact and a break contact of the relay switch RS, respectively. The terminal 11b is connected to the terminal 11j via the exciting coil 12 of the socket-type switch-equipped relay 10.

The terminal 11c, as shown in Figure 2, is connected to the common terminal of the mechanical switch MS ₁ which is incorporated integrally on the socket-type switch with a relay 10. Then, the terminal 11f and 11g are respectively connected to the make contact and break contact of the mechanical switch MS _1. Similarly, the terminals 11h and 11i are connected to the mechanical switch MS ₂ integrated with the relay 10 with the socket type switch.
To the break contact and a make contact, and terminal 11k is the common terminal of the mechanical switch MS _2, are connected respectively.

The relay with socket type switch 10 incorporates the relay switch RS and the mechanical switches MS ₁ and MS ₂ integrally, and covers the outside thereof with a case 13. The terminal 11 is formed on the formation surface 13a on the bottom surface side of the socket-type switch-equipped relay 10. Relay with socket type switch 1
Reference numeral 0 indicates that the terminal 11 is inserted into a corresponding hole or the like provided in a base (not shown) to which the terminal 11 is attached, so that the base 11 is connected to a circuit of the base. Then, as the operation of the mechanical switch MS _1, MS ₂ is facilitated mounted to a base, a mechanical switch MS _1, MS ₂ is attached to the operating surface 13b opposite to the forming surface 13a. In this case, the mechanical switches MS ₁ and MS ₂
In order to improve the operability of the switch, the operation surface 13b may be provided with switch numbers and contact types.

Although the number of mechanical switches is two in the above embodiment, the number is not limited to two, and at least one mechanical switch is provided.
It is only necessary to provide two mechanical switches. Also, the above-mentioned relay is a closed type in a case,
Any relay of the plastic type or the hermetic seal type may be a relay of the socket type. Further, as shown in FIG. ₂ , the mechanical switches MS ₁ and MS ₂ use dip switches.
However, it is not limited to this. For example, it may be any of a push button switch, a selector switch, a seesaw switch, a toggle switch, a slide switch, or a rotary switch.

FIG. 3 shows an example in which the socket-type relay switch thus configured is incorporated in a sequence circuit.

In the figure, between two different power lines 14 and 15,
To connect to insert a socket-type switch with relay 10 _1. In this case, the mechanical switch is two and the MS ₃ and MS _4. The power supply line 14, the common terminal of the mechanical switch MS ₃ is connected. On one break contact side comprising a contact of the mechanical switch MS _3, one terminal of an external switch (mechanical switch) ES differ from the socket-type switch with the relay 10 _1, mechanical to make contact side serving as the other one terminal of the switch MS ₄ are respectively connected. The other terminals of the external switch ES and the mechanical switch MS ₄ are connected to a socket type switch-equipped relay 1.
0 through the _first body (excitation coil section) is connected to the power supply line 15. Further, in parallel with these mechanical switch MS _3, MS _4, between the power supply line 14 and 15, a series circuit consisting of the relay switch RS ₁ and the lamp 16 are connected.

As described above, if a relay provided with a mechanical switch is used as a socket type relay, automatic-manual switching and operation check can be performed by using only one relay. In this case, the mechanical switch MS _3, MS ₄ and relay switch RS _1, since it is arranged on the same socket switches with relays 10 _1, external switching to provide separate wiring or on base attaching the relay The restrictions on the mounting location can be greatly eased.

FIG. 4 shows another embodiment in which the socket type relay switch is incorporated in a sequence circuit.

In the figure, between the two power supply lines 14 and 15, to insert the socket switch with a relay 10 ₂ having two mechanical switches MS ₃ and MS ₅ connected. In this case, power line 1
The 4, the common terminal of the mechanical switch MS ₃ is connected. This, the break contact side of the one contact of the mechanical switch MS ₃ is attached this socket type switch relay
10 External switch (mechanical switch) ES different from ₂
Is connected to one of the terminals. The other terminal of the external switch ES, along with make contact serving as the other of the socket-type switches with relays 10 _2, relay socketed switch
10 through the _second exciting coil unit is connected to a power supply line 15. Further, a parallel thereto, between the power supply line 14 and 15 are connected in series circuit consisting of the relay switch RS ₂ and the lamp 16 is further connected to a mechanical switch MS ₅ in parallel with the relay switch RS _2.

Even in such a circuit configuration, if the above-described relay with socket type switch is used, one relay can automatically
An operation that satisfies the three functions of manual switching, operation check, and automatic detection can be performed.

FIG. 5 shows still another embodiment in which the socket type relay switch is incorporated in a sequence circuit.

In the figure, between the two power supply lines 14 and 15, a series circuit consisting of the excitation coil of the external switch ES ₁ and socket type switch with a relay 10 _3, the excitation of the external switch ES ₂ and the socket relays 17 A series circuit composed of a coil unit is connected in parallel. Further, the power supply line 14, a parallel circuit composed of the mechanical switch MS ₆ and the relay switch RS ₃ of the socket-type switches with relays 10 ₃ are connected. This parallel circuit is connected to the power supply line 15 via the relay switch RS ₅ of the socket type relay 17 and the buzzer 18. Furthermore between the power supply lines 14 and 15, a mechanical switch MS ₇ of the socket-type switches with relays 10 ₃ and the relay switch RS ₄
, The relay switch RS ₆ of the socket type relay 17 and the lamp 16 are connected in series.

In this circuit configuration, for example, of the operating conditions of the buzzer 18, of the relay connected in series to the external switch ES _1, if you want to exclude the conditions of relay switch RS ₃ and RS _4, above socket using switches with relays 10 _3, it is possible to meet this condition. That is,
Instead of actuating the relay switch RS ₃ and RS _4, for opening and closing the mechanical switch MS _6, MS _7. Thus, regardless of the condition of the relay switch RS ₃ and RS _4, it is possible to check the operating state of the circuit.

As described above, since one relay has the function of the relay switch and the function of the mechanical switch, a manual operation circuit can be configured irrespective of the relay circuit, and thus the cost can be reduced in terms of circuit fabrication. It becomes possible.

Further, as a countermeasure for a circuit abnormality such as a sequence circuit, a relay with a switch is provided in place of a conventional relay and a mechanical switch is operated to prevent a circuit break. As a result, there is an advantage that the number of processing steps for dealing with an abnormality in the circuit can be reduced, and the necessity of conditions can be simplified.

[Effects of the Invention] As described above, according to the present invention, even if a mechanical switch is provided in a relay circuit, there is no restriction between the base and the mechanical switch, and the cost is not increased. A relay with a socket-type switch that can be manufactured can be provided.
