Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breaker distributor for branching three secondary current output terminals of a breaker incorporated in a distribution board, a distribution board, a control board or the like into various devices such as a motor.

[0002]

2. Description of the Related Art For example, in order to arrange a plurality of motors in a factory, it is necessary to branch three secondary current output terminals of a breaker incorporated in a distribution board, a distribution board, a control board or the like into various devices such as a motor. However, there is no known distributor for the breaker.

[0003]

Therefore, conventionally, the ends of the three-phase electric wires of each motor are bundled in the same kind to form three bundles, and crimp terminals are attached to the ends of the bundles, respectively.
Each crimp terminal was attached to each of the three terminals of the breaker.

In this case, when the capacity or the number of motors changes, or when a contact failure occurs, it is necessary to remove the crimp terminal from the bundle of electric wires and perform the above work again each time, which is very troublesome. Met.

Therefore, a bus bar is also used. This is to prepare three bus bars cut to the required length, open a breaker terminal connection hole at one end of the bus bar, and make a tap to open a plurality of branch line connection holes from one end to the other. After that, one end of each bus bar is connected to each secondary current output terminal of the breaker, and electric wires from each motor are connected to the branch line connection holes.

In this case, it is necessary to support the bus bar in an insulated state, and this series of operations is extremely troublesome.

The object of the present invention is to use it to perform an operation of branching three secondary current output terminals of a breaker incorporated in a distribution board, a distribution board, a control board or the like into various devices such as a motor. easy and Do Li Kui manufacture is to provide easy blanking <br/> breaker for partial collectors.

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

FIGS. 1 to 4 show a first embodiment of a breaker distributor according to the present invention. The breaker distributor (2) is incorporated in a distribution board, a distribution board, a control panel or the like. It is for branching the three secondary current extraction terminals (1a) of the breaker (1) to various devices such as motors, and is connected to the breaker (1) through the wiring (12) for connection. Format. The breaker distributor (2) has a board (3) with a through hole (8) for mounting at a required location, three bus bars (4), and three bus bars (4) on the board (3). ) A plurality of insulating supports (5) that are supported in parallel on top of each other, and a protective cover (6) attached to the substrate (3) via spacers (7).

A breaker terminal connecting hole (9) is formed at one end of each bus bar (4), and an insulating support mounting through hole (1) is provided at a position closer to the inner side of the breaker terminal connecting hole (9) and at the other end.
8) is opened, and multiple branch line connection holes are provided between both through holes (18).
(10) are spaced at a predetermined interval. Each bus bar
(4) is plated with nickel to prevent oxidation. In addition to nickel plating, the bus bar (4) may be tin plated, solder plated, silver plated, gold plated, or the like. The breaker terminal connection hole (9) is a through hole, and the branch line connection hole (10) is a screw hole.

The substrate (3) is a chromate-treated rectangular iron plate, and the length of the substrate (3) and the length of the bus bar (4) are equal. Insulation support on board (3)
(5) The male screw (13) for mounting and the male screw (14) for spacer (7) are fixed by spot welding.

The insulation support (5) is made by fixing nuts (16) embedded in both bottom surface parts (15a) of an acrylic cylindrical insulator (15). One bottom surface part (15a) Nuts (16) are screwed into male threads (13) for mounting the insulation support (5) and are fixed to the board (3). Bottom of the other
(15a) is provided with a hole (17) for inserting a tool when fixing the insulating support (5) to the substrate (3). Then, in the nut on the other bottom part (15a) of the insulating support (5), screw (1) inserted through the through hole (18) of each bus bar (4).
9) is screwed and fixed to each bus bar (4).

The height of the insulation support (5) depends on each bus bar.
The height of (4) is set to be almost equal to the height from the wall surface of each take-out terminal (1a) of the breaker (1). The height of each bus bar (4) can also be adjusted by changing the thickness of the substrate (3). Also insulation supports (5)
Are arranged at intervals corresponding to the intervals between the takeout terminals (1a).

The spacer (7) is formed by covering the side portion of the iron round bar (20) with an insulating tube (21) made of vinyl chloride.
A spacer (7) fixed to the board (3) is attached to one end of it.
A female screw portion (22) to be screwed into the male screw (14) for the hook is formed, and a male screw portion (23) is formed at the other end. The male screw part (23) is projected from the holes (24) formed at the four corners of the protective cover (6), and the cap nut (25) is screwed into this.

The protective cover (6) is made of acrylic resin and is an orange transparent plate. Therefore, it is easy to recognize that it is dangerous and the inside of the distributor (2) for breaker is easy to understand.

This breaker distributor is used as follows.

After removing the protective cover (6) , the protective cover (6) is attached below the breaker (1) so that the breaker terminal connection hole (9) is on the upper side. This work is done by mounting through holes on the board (3).
(8) Since is opened, the screw passes through the through-hole (8) (2
All you have to do is screw in 6). Then, connect each secondary current extraction terminal (1a) of the breaker (1) to the breaker terminal connection hole (9) of each bus bar (4) through the wiring (12) for connection, and connect the bus bar (4). The branch wires (11) to various devices such as motors are connected to the branch wire connection holes (10). Finally, the protective cover (6) is attached and the branching work is completed .

FIGS. 5 to 7 show a second embodiment of the breaker distributor according to the present invention. The breaker distributor (32) of this embodiment is a secondary current take-off device for the breaker (1). It is of the type directly connected to the terminal (1a). 5 to 7, the same components as those in FIGS. 1 to 4 are designated by the same reference numerals and the description thereof will be omitted. In this breaker distributor (32), the length of each bus bar (34) is larger than the length of the board (33), and one end of each bus bar (34) is longer than the board (33) and one end of the protective cover (36). It is projected. Breaker terminal connection holes (39) are provided in each of these protruding parts, and the end where each breaker terminal connection hole (39) is provided is not supported by the insulating support (5) and is free. It has become.

In this breaker distributor, the breaker terminal connection hole (39) is directly connected to each terminal of the breaker (1) with a screw. This work is designed such that the height of the insulation support (5) holds each bus bar (4) at a height above the wall of each breakout terminal (1a) of the breaker (1), and Since 5) is arranged at an interval corresponding to the interval between the take-out terminals (1a), it can be performed with one touch.
