Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a mounting device for embedding two surface-mounted circuit switches or disconnectors side by side in an operation panel or the like.

[Prior art and its problems] When installing circuit breakers on an operation panel, etc., there are two types: surface-mounting type and recessed-mounting type. It is advantageous if one circuit or disconnector is configured so that it can be used in common for both mounting types. In addition, it is desirable that the mounting members be inexpensive, require less man-hours for mounting, and do not impair the appearance. Taking these points into consideration, we devised and applied for a mounting device for circuits and disconnectors as shown in Fig. 1.
(Utility Application No. 58-66649) In Fig. 1, a circuit breaker main body (hereinafter simply referred to as a breaker) 1 has a contact point inside, and the upper operation surface 1a is used to open and close the contact. A lever 2 is protruded, and a connecting terminal 3 to the outside and a mounting leg 1b are protruded from the side surface. In order to install this shield disconnector 1 on the operation panel as a surface-mounting type, place the bottom of the shield disconnector 1 on the panel surface, and place the legs 1b
Pass the mounting screw through and tighten it. This shield disconnector 1 is installed in the operation panel 4 through the embedding hole 1a.
To explain the structure when inserting and installing it in the breaker, there is a strip-shaped groove 1c on the side of the breaker 1 that is parallel to the operating surface, or in other words, the mounting surface (the surface of the board on which the breaker is installed).
is provided over the entire circumference, and is configured such that a mounting member 5, which will be described next, engages with this groove 1c. That is, the mounting member 5 is made of elastic material such as resin, and is punched out into a substantially U-shape having a thickness that engages with the groove 1c, and screw holes 5b are provided in each of the legs 5a. A protrusion 5c is provided on the inside.

In order to attach the sheath cutter 1 to the panel surface 4, the inner peripheral edge of the mounting member 5 is first engaged with the groove 1c of the sheath cutter 1. At this time, if both legs 5a are opened by the length of the protrusion 5c and embedded using the elasticity of the mounting member 5, the protrusion 5c
c engages with the groove 1c on the opposite side of the groove 1c in which the body of the mounting member 5 was engaged, and the mounting member 5 is attached as if holding the sheath disconnector 1, and the sheath disconnector 1 is shaped like a brim. protrudes from the surrounding wall of Moreover, it is tightly engaged with the groove 1c and does not easily fall off due to the friction between the inner wall and the mounting member 5. Here, the breaker 1 is inserted from below the embedded hole 4a of the panel 4 so that the operation surface 1a is exposed on the panel surface, and the mounting member 5 is brought into contact with the periphery of the embedded hole 4a. Then, it may be screwed into the screw hole 5b through the mounting hole 4b provided in advance around the periphery of the embedding hole 4a of the board. Operation surface 1 of this recessed type disconnector
The protruding dimension of a from the board surface is the dimension obtained by subtracting the thickness of the board from the distance between the operating surface 1a of the shredder 1 and the groove 1c.

The mounting structure of this cutter is simple and inexpensive, requires less man-hours for installation, and has an excellent appearance. However, this mounting structure is designed to mount only one breaker. Here, you may want to line up two single-pole type circuit breakers to make a two-pole type, or even three to line up three-phase circuits, so multiple lines and breakers can be installed at the same time. It is convenient to install.

[Purpose of invention]

The present invention was devised in view of the above points, and its purpose is to provide a mounting device with an excellent appearance and a reduced number of man-hours for installing two side-by-side disconnectors in a recessed manner on an operation panel, etc. do.

[Key points of the idea]

The present invention provides an annular groove parallel to the operation surface on the side surface of the circuit and disconnector body, and engages the inner periphery of a substantially U-shaped elastic mounting member with the groove to form a collar-shaped mounting portion. The circuit is formed such that the circuit or disconnector body is inserted into a hole in a board to which it is to be attached, and the mounting member is brought into contact with the periphery of the hole, and the circuit is mounted with the operating surface exposed on the board surface. In the installation device for the shield cutter, two
The circuit breakers and disconnectors of the pedestals are overlapped, and steps are provided on the end surfaces of both legs of the mounting member so that they engage when they abut each other, and the two mounting members are placed on both sides of the two circuit breakers and breakers. The two circuit breakers are fitted into the respective grooves and their end faces abut each other, so that the two circuit breakers and disconnectors are integrally installed.
This is a system in which two breaker disconnectors are placed side by side and integrated into one, allowing for embedded installation with an excellent appearance with less man-hours.

[Example of idea]

Next, an embodiment of the present invention will be described in detail based on the shingle breaker and its mounting member shown in FIGS. 2 and 3. In FIG. 2, the shingle breaker 1 is the same as a conventional one, so a description of its structure will be omitted. The structure in which the disconnector 1 is mounted on the operation panel as a recessed type is that the disconnector 1 side is exactly the same as the conventional one, with a band-shaped groove 1c parallel to the operation surface 1a running all around the side. It is set up. A plurality of such cutters 1, in this case two cutters 1-1, are stacked on top of each other with the operation surface 1a being the same plane, and the grooves 1c-1c of the cutters 1-1 are also overlapped. It surrounds these two shiya disconnectors in succession. The mounting members 5 of this sheath disconnector 1 are made of elastic material such as resin, similar to conventional ones, and are punched out into a substantially U-shape from a plate material thick enough to engage with the groove 1c, and are mounted on the legs 5a, respectively. A hole 5b is provided, and a protrusion 5c is provided inside the ends of both legs 5a. but,
This mounting member 5 has steps 5d and 5 at the ends of both legs 5a.
e is provided. When two such mounting members are provided and the ends of both legs 5a-5a of both mounting members 5-5 are abutted against each other, the respective steps 5d,
5e engage with each other to form a quadrilateral mounting member 5-5 of uniform thickness. Therefore, if the mounting member 5-5 is engaged with the groove 1c-1c from both sides of the shredder 1-1 so as to surround the two shredder cutters 1-1, which are stacked on top of each other, the As shown in FIG. 3, the ends of the mounting members 5-5 are engaged with each other and are pressed and coupled by the inner wall of the groove 1c. Of course, when the mounting member 5 is engaged with the groove 1c, the legs 5d are opened by the length of the protrusion 5c, but when the mounting member 5 is completely engaged with the cutter 1, the protrusion 5c is
It fits into the groove 1c between the two ends and the disconnector 1-1, and returns to its original shape. In this way, the two shear disconnectors are surrounded by the two mounting members and integrated, and a collar-shaped attachment portion is formed around the two shear disconnectors. Therefore, it can be attached to an operation panel or the like in the same way as in the case of a single conventional disconnector. This attachment method has already been described, so its explanation will be omitted.

According to this mounting device, even when there is only one shroud breaker, it can be mounted using one same mounting member, and when there are a plurality of shredder breakers, it can be mounted using two mounting members. However, when installing three stacked Shiya disconnectors, one mounting member needs to have legs long enough to surround the two stacked Shiya disconnectors. Needless to say. In this way, when installing the shield disconnector as a recessed type on an operation panel, the installation process is almost the same whether one unit is installed or two units are installed, and it is easy. It also has an excellent appearance because only the operating surface is exposed on the board.

In addition, when two single-pole switchboards and disconnectors are used as a multi-pole switch, as shown in FIGS. 2 and 3, the levers 2 can be connected to each other by connecting pieces 7 to facilitate operation.

[Effect of idea]

As mentioned above, the circuit breakers and disconnectors mounting device according to the present invention requires significantly less installation work because two switches and disconnectors can be installed at the same time, and only the operating surfaces of the cutters and disconnectors are exposed on the panel surface. Therefore, the appearance is also excellent.
