Abstract

PURPOSE:To facilitate the connection of a terminal device, and secure the insulation by providing an insulating plate between a first terminal and a second terminal of a case, which are arranged to be adjacent to each other, freely to put it in/out. CONSTITUTION:A recessed part 21 for housing an insulating plate 4 freely to be put in/out is formed over a base and a cover forming a case 1, and a stopper for preventing slip is formed in an opening edge. A projecting piece to be locked with the stopper is formed in the insulating plate 4 to prevent the slip of the insulating plate 4 from the case 1 and the missing thereof, and an operating part 24 is provided in the outer end. In the case of connection to the first terminal 2 and the second terminal 3, the insulating plate 4 is put in the case 1, and is pull out after the connection. Consequently, the connection is performed without a hindrance of the insulating plate 4, and the insulation between the terminals is secured by pulling out the insulation plate 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device applied to a circuit breaker or the like.

[0002]

2. Description of the Related Art When wiring a commercial power source and a low voltage power source in the same panel, there is an increasing need for circuit separation.
In that case, in a remote control type circuit breaker having a low voltage circuit and a commercial circuit in the same module, the main terminal and the operation terminal are often mixed in the same end face portion of the case. Therefore, after connecting the main terminal and the operation terminal, an insulating plate for separating the wiring is installed between the main terminal and the operation terminal.

[0003]

However, since this insulating plate is a separate part, it must be prepared at the time of connection, but it may be lost. On the other hand, if the insulating plate is provided integrally with the case, there is a problem that the insulating plate interferes with the connection of the main terminal and the operation terminal, and the like.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a terminal device which can be easily connected and can ensure insulation.

[0005]

The terminal device of the present invention comprises:
A case, a first terminal installed in the case, a second terminal disposed adjacent to the first terminal of the case, a first terminal of the case, and a second terminal of the case And an insulating plate arranged so as to be able to be taken in and out.

[0006]

According to the structure of the present invention, when connecting to the first terminal and the second terminal, the insulating plate is pulled into the case, and after connecting, the insulating plate is pulled out. Therefore, the insulating plate can be connected without disturbing it, and the insulation between the terminals can be secured by pulling out the insulating plate. Moreover, since the insulating plate is arranged so that it can be taken in and out of the case, there is no need to prepare the insulating plate when connecting the wires, and there is no fear of loss. Further, it becomes possible to display a terminal number or the like on the surface of the insulating plate to prevent misconnection.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A remote control type circuit breaker to which an embodiment of the present invention is applied will be described with reference to FIGS. That is, this terminal device has the case 1, the first terminal 2, the second terminal 3, and the insulating plate 4. The case 1 serves as a terminal block, but the embodiment is a device stand of a circuit breaker, and includes a base 5 having an opening on a side surface and a cover 6 closing the opening as shown in FIG. Case 1
The first movable contactor 9 of the contact portion is opened and closed by operating the handle 8 pivotally supported by the fixed shaft 7, and the first movable contactor 9 is opened by the operation of the abnormal current detecting means 10 and 11. It has a well-known mechanism section 12 built-in. In addition, the electromagnet 16 is built in, and the bent portion is rotatably supported by the fixed shaft 13.
The second movable contactor 15 of the contact portion is provided on one piece of the L-shaped lever 14.
And the plunger 17 of the electromagnet 16 is connected to the other piece to open and close the second movable contactor 15 by a remote signal.
Reference numeral 18 is an arc extinguishing device, and 25 is a display unit for displaying the open / closed state of the second movable contactor 15.

The first terminals 2 are installed in the case 1 and, in the embodiment, are provided at both ends of the case 1 as shown in FIG. 3, one of which is a load side terminal of the main circuit and the other of which is a power source side terminal. In addition, the abnormal current detection means 10 and 11, the first movable contact 9 and the second movable contact 15 are connected therebetween. The second terminal 3 is arranged adjacent to the first terminal 2 of the case 1, but in the embodiment, the lower side of the first terminal 2 that is the load side closer to the electromagnet 16, that is, the mounting surface 1 of the case 1.
It is provided on the 9 side and is connected to the coil 20 of the electromagnet 16 via a control circuit (not shown) when necessary. That is, when a remote signal is applied to the second terminal 3 in one direction, a current flows in one direction in the coil 20, the electromagnet 16 is excited in one direction, and the plunger 17 rotates in one direction. Similarly, when a remote signal is applied to the second terminal 3 in the other direction, the plunger 17 rotates in the other direction, and these operations cause the second movable contact 15 to open and close.

The insulating plate 4 is arranged between the first terminal 2 and the second terminal 3 of the case 1 so as to be able to be taken in and out. That is, the base 5 forming the case 1 as shown in FIG.
A recess 21 for accommodating the insulating plate 4 in a retractable manner is formed across the cover 6, and a stopper 22 for preventing removal is formed at the opening edge of the recess 21. The insulating plate 4 is housed in the recess 21 so that it can be freely taken in and out, and a projecting piece 23 that engages with the stopper 22 is formed at the inner end of the insulating plate 4 to regulate the maximum protruding amount so as not to come off from the case 1. An operation unit 24 is provided at the end. 5 and 6 show a state in which the insulating plate 4 is retracted, and in this state, the first terminal 2 and the second terminal 3 are connected. In this case, since the electromagnet 16 and its control circuit are often attached prior to the first terminal 2, by attaching the second terminal 3 below the first terminal 2, Easy to connect. 1 to 3 show a state in which the insulating plate 4 is projected, and is used after being drawn out after connection to ensure insulation between terminals.

The surface of the insulating plate 4 may be provided with a terminal number or the like for preventing misconnection. Although the first terminal 2 is used as the main circuit terminal and the second terminal 3 is used as the operation terminal of the electromagnet 16, other auxiliary terminals such as a detection switch for detecting a trip state or an operating state of the contact portion may be used. Good.

[0011]

According to the terminal device of the present invention, when connecting the first terminal and the second terminal, the insulating plate is pulled into the case, and the insulating plate is pulled out after the connection, so that the insulating plate becomes an obstacle. It is possible to connect the wires without any need and to secure the insulation between the terminals by pulling out the insulating plate.
Moreover, since the insulating plate is arranged so that it can be taken in and out of the case, there is no need to prepare the insulating plate when connecting the wires, and there is no fear of loss. Further, there is an effect that it is possible to display a terminal number or the like on the surface of the insulating plate to prevent misconnection.
