Description

[Detailed Description of the Invention] This invention relates to a circuit breaker and a circuit breaker, in particular, a circuit breaker and breaker that has been improved in the portion that abuts the top plate provided on the operation handle side.

First, an explanation will be given of a collective type wiring sheath disconnector and a circuit sheath disconnector that are housed in a conventional power distribution box.

In Fig. 1, 1 is a collective type wiring disconnector;
1A is a housing with a built-in chopping element, 1B is an operating handle for manually opening and closing the chopping element inside this housing 1A, 1C is a raised protrusion around the operating handle 1B, and 1D is a housing. A recess for mounting formed in the lower part of the housing 1A, 1E is a terminal connected to the insulation element inside the housing 1A, and 1F is a tightening hole for screwing a conductor (not shown) connected to this terminal 1E. It's a screw.

In Fig. 2, 2 is a circuit cutter, 2A is a base on which a cutter and cutter element is installed, 2B is a cover that protects the cutter and cutter element together with the base 2A, and 2C is a cutter in the base 2A. An operation handle for manually opening and closing the element, 2D is a raised protrusion around the operation handle 2C, 2E is a terminal connected to the shingle cutting element in the base 2A, and 2F is a conductor connected to this terminal 2D. (not shown). Note that B is the first plane of the circuit breaker 2. Figure 3 shows a collective type wiring sheath breaker 1 and a circuit breaker 2.
This shows the state in which they are installed side by side.

3 is the first fixing plate to which the collective type wiring sheath breaker 1 and the circuit sheath breaker 2 are attached; 4 is the A side of the collective type wiring sheath breaker 1 and the A side of the circuit sheath breaker 2; A top plate 5 is attached in such a way that the projections 1C and 2D of the two cutters and disconnectors 1 and 2 are exposed, and the top plate 5 is in contact with the concave portion 1D and is attached to a common type wiring cutter. This is a mounting bracket for attaching the fixture 1 to the fixing plate 3.

Figure 3 shows the state in which the collective type wiring/disconnector 1 and the circuit/disconnector 2 are used in a distribution box (not shown) etc. that is attached to a distribution board (not shown). . That is, a circuit sheath disconnector 2 and a plurality of collective wiring sheath disconnectors 1 connected to the circuit sheath breaker 2 are attached to a fixed plate 3 and housed in a distribution box.

However, the circuit sheath breaker 2 and the collective wiring sheath breaker 1 housed in the distribution box may be made by the same company.

Therefore, through the cooperation of those in the same industry, the heights from the mounting surface A to the plane B shown in FIGS. 1 and 2, that is, H and h, have been guaranteed to be H=h. By the way, as a representative example of the case where the collective type wiring/disconnector 1 is attached to a distribution box etc., in addition to the case where it is directly fixed to the fixing plate 3 as described above, the collective type wiring/disconnecting switch 1 is attached to a distribution box etc. as shown in Fig. 4. 1 may be fixed to the fixing plate 3 while being fixed to the second fixing plate 6. Therefore, the configuration of the collective type wiring shield and disconnector 1 and the second fixing plate 6 is as follows: By bringing the tip of the stopper 6A into contact with one of the recesses 1D of the collective type wiring sheath disconnector 1, and then pushing the collective type wiring sheath disconnector 1, the first locking part is removed. 6A, and the elasticity of the second locking part 6B causes the second locking part 6B to be pressed into the recess 1D of the collective type wiring sheath disconnector 1. The protrusion of part 6B is designed to lock.

In such a configuration, the installation of the circuit breaker 1 for collective type wiring becomes high, so when the top plate 4 is attached, the connection between the circuit breaker 2 and the top plate 4 as shown in FIG. A gap t equal to the thickness of the second fixing plate 6 is provided between
occurs. However, since this gap t is not in contact with the plane of the circuit or disconnector 2, it has the disadvantage that the top plate 4 is deformed even when subjected to impact.

This invention was made in order to eliminate the above-mentioned drawbacks, and it is an object to provide a circuit breaker or breaker in which first and second planes and a protrusion are formed around the operating handle of the circuit breaker or breaker. That is.

Next, an example of the effect of this invention is shown in Figure 5A.
B, C and Figure 6 A, B will be explained. That is, in the figure, a second layer 7 is laminated on the first plane B of the circuit breaker 2, projects around the operating handle 2C by a predetermined height, and is smaller in area than the first plane B. is the plane of Further, the protrusion 2D is the second
The second flat surface 7 is laminated to protrude around the operating handle 2C by a predetermined height, and is smaller in area than the second flat surface.

In such a configuration, as shown in FIG.
When attaching the top plate 4 directly to the first fixing plate 3, attach the top plate 4 to the first fixing plate 3, respectively.
can come into contact with plane B of .

In addition, as shown in FIG.
When it is fixed to , the planes in contact with the top plate 4 are the first plane B of the collective type wiring sheath breaker 1 and the second plane 7 of the circuit sheath breaker 2.

As described above, according to this invention, by providing the circuit board or disconnector with the first plane and the second plane that can selectively come into contact with the top plate, it is possible to install, for example, a collective type wiring board or disconnector. Regardless of whether the first fixing plate or the second fixing plate is used alone or in combination, there will be no gap between the top plate and the circuit or disconnector by simply opening the corresponding window holes in the top plate. This has the effect that the top plate is not subject to damage such as bending due to impact or the like.
