Description

[Detailed description of the invention] This invention relates to a composite breaker that combines an earth leakage breaker and a wiring breaker when these are used in the same place, for example in a residential distribution board. .

Conventionally, as shown in FIG. 1A, this type of composite breaker has been constructed by mounting an earth leakage breaker 1 and circuit breakers 2, 3, 4.5, called safety breakers, etc. on a common base 6. A current is passed through the power supply side electric wires 7a and 7b to the earth leakage breaker 1, and the earth leakage breaker 1 and the circuit breakers 2, 3, 4, .
5 is a connection line 8a.

8b, 9a, 9b, 10a, iob, lla.

11b, and load wires 12a, 12b, 13a are connected to the load side of the circuit breakers 2, 3, 4.5.

Connect 13b, 14a, 14b, 15a, 15b,
There was a structure that wired each load.

FIG. 1B is a wiring diagram of the composite breaker of FIG. 1A.

Since the conventional composite circuit breaker is constructed as described above, the earth leakage breaker 1 has mounting screws 20, 21, and the circuit breakers 2, 3, 4.5 have mounting screws 22, 23, respectively.
It must be installed on the base 6 at angles of 24, 25, 26, 27° 28.29, and it is also necessary to connect the earth leakage breaker and the wiring breaker with a large number of connection wires, which requires a large number of installations and wiring. It requires a lot of man-hours, uses a large number of mounting screws and wires, and requires a power distribution box to mount the earth leakage breaker 1 and wiring breakers 2, 3, 4.5 to the same base 6. However, there were drawbacks such as not being resource-saving, requiring a large amount of materials, and being expensive.

The object of this invention is to provide a composite circuit breaker that eliminates the drawbacks of the conventional circuit breaker as described above.

In recent years, the use of combinations of earth leakage circuit breakers and wiring circuit breakers has increased significantly, mainly for residential use. An earth leakage breaker with the basic function of a circuit breaker and a wiring breaker with the function of a power distribution breaker are housed integrally within the same plastic base and cover,
Connecting wiring for these disconnection parts is performed within the base and cover, saving labor and resources for wiring, omitting a distribution box, and providing a compact, inexpensive, and easy-to-wire combination and disconnector. .

In the following, the invention will be explained with reference to the illustrated embodiments.

In this invention, as shown in FIGS. 2A and 2B, an earth leakage breaker 41 and a wiring breaker 42, 43, 44, 45 are housed in the base 30 and cover 31, and the earth leakage breaker 41 and the wiring Breaking parts 42, 43, 44, 4
5 connection wiring 48a, 48b, 49a, 49
b, 50a.

50b, 51a, and 51b are also provided within the base 30 and the cover 31.

Therefore, on the cover 31, there is a handle 61 for opening and closing the earth leakage breaker 41, a test button 66 for checking the operation of the earth leakage breaker, and handles 62, 63 for opening and closing the wiring breaker. , 64, and 65 are scratched.

Further on the cover 31 is a terminal cover 56 for preventing exposure of the live parts of the connection parts of the power supply side electric wires 47a and 47b for supplying electricity from the power source to the earth leakage breaker 41, and a terminal cover 56 connected to each wiring breaker. Load side electric wires 52a, 52b,
53a.

Terminal covers 57, 58, 59, 60 are provided to prevent live parts of connection parts such as 53b, 54a, 54b, 55a, 55b from being exposed.

The base 30 and the cover 31 are attached to a board surface (not shown) with attachment screws 67 and grooves 8 passed through holes passing through them.

The composite circuit breaker having the above configuration has a power supply side electric wire 47a connected to the power supply side of the earth leakage breaker 41.

The current supplied from 47b and passed through the earth leakage breaker 41 is connected to connecting wires 48a, 48b, and 49a.

49b, 50at, 50b, 51a, and 51b, it flows to each of the wiring interrupting parts 42, 43, 44, and 45.

Each of the breaker parts 42, 43, 44, 45 is electrically independently buttoned by a partition part (not shown) provided on the base 30 and the cover 31, and the breaker part 42 can be opened and closed by operating the handle 62. The on/off of the load can be controlled through the load wires 52a and 52b.

Similarly, by operating the handles 63, 64, and 65, the respective loads can be controlled by opening and closing the breaker parts 43, 44, and 45.

In the above embodiment, the earth leakage breaker is located closest to the power supply side, but the earth leakage breaker and the other breaker may be arranged in any order. For example, one of the wiring breaker parts closest to the power supply side may be arranged in any order. The earth leakage breaker may be provided next, or the earth leakage breaker may be provided farthest from the power source side.

In addition, although a configuration in which there are multiple wiring breaker parts for the earth leakage breaker part is shown, the same applies even if there are multiple earth leakage breaker parts and one wiring breaker part, or if both of them are configured in the number of collars. It has the effect of

As described above, according to this invention, the earth leakage breaker and the wiring breaker are configured in one base and cover, and the load side of the earth leakage breaker and the power supply side of the wiring breaker are connected to the base and the wiring breaker. Wiring is done inside the cover, and terminal covers are provided to prevent live parts from being exposed on the power supply side and load side wire connection terminals, so even if there are many branch circuits, only one connection work is required on the power supply side. It is only necessary to connect the load side at each point and load side as necessary, which saves labor in wiring work.In addition, since conventionally the connecting wire between the earth leakage breaker and the wiring breaker was exposed, it is necessary to protect the live parts and the wiring. For safety reasons, a distribution box was required to secure the circuit breaker and to surround it, but this invention eliminates the need for a distribution box, greatly saving resources, being inexpensive and easy to work with. This has the effect of providing a circuit breaker.
