Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electrical insulating board that covers and protects electrically charged parts of printed circuit boards of electrical equipment.

Conventional Technology In recent years, electrical insulating boards that cover live parts of printed circuit boards in remote controllers of electrical equipment have been used not only for simple insulation purposes, but also for purposes such as protecting electronic components from static electricity held by workers when wiring cables. Its uses are expanding.

An example of a conventional remote controller for electrical equipment will be described below with reference to FIG. FIG. 4 is a partially cutaway perspective view of a remote control case showing how a conventional remote controller for electrical equipment is used. In FIG. 4, the electrical insulating board 1 is used together with the printed circuit board 6 in order to cover and insulate the live parts of the printed circuit board 6.
Remote control (hereinafter referred to as remote control)
It is fixed to case 9. Reference numerals 2 and 3 denote terminal plates for connection, which are fixed to the printed circuit board 6 and further connected to the terminal plates 4 and 5 of the remote control cord 8.

Problems to be Solved by the Invention However, with the above configuration, when a contractor connects the terminal plates 4 and 5 to the wiring terminal plates 2 and 3 during equipment installation, it is difficult to determine the connection direction of the terminal plates 4 and 5. Because there is no regulation, when the terminal plate 4, which is originally attached to the wiring terminal plate 2 from the right side in Fig. 4, is connected from the lower left as shown in Fig. 4, the terminal plate 4 is attached to the wiring terminal plate 2, However, there was a problem in that 3 were short-circuited to each other. Furthermore, when the terminal boards 4 and 5 are connected from the left side, the space between the wiring terminal board and the remote control case 9 is narrower on the left side, so the remote control cord 8 is sandwiched between the remote control case 9 and the back cover 10, and the remote control There was a problem in that the cord 8 was damaged. The aforementioned short-circuiting of the connection terminal plates 2 and 3 and damage to the remote control cord 8 have great effects, such as malfunction and failure of the equipment.

In view of the above-mentioned problems, the present invention provides a remote controller for electrical equipment that regulates the connection direction of terminal boards with a simple configuration and prevents short circuits between terminal boards for connection and damage to remote control cords.

Means for Solving the Problems In order to solve the above-mentioned problems, the remote controller for electrical equipment of the present invention includes a plurality of connecting terminal boards with adjacent two corners cut and raised, and a plurality of the above-mentioned connecting terminal boards. a printed circuit board to be installed, a terminal plate screwed to each of the terminal boards for connection, and an electrically insulating board that covers an electrically charged part of the printed board, and the electrically insulating board has a plurality of terminal boards for electrical connection. An opening for protrusion is provided, and the opening is formed by cutting and raising one side opposite to the cutting and raising of the connection terminal plate.

Effect: By cutting and raising one side of the opening of the electrical insulating board opposite to the cutting and raising of the terminal board for connection, the connection terminal board can be seen from the direction of cutting and raising the opening of the electrically insulating board. It becomes impossible to connect the terminal plate to the board. Therefore, the connecting direction of the terminal plates can be regulated, and it is possible to prevent short circuits between the wiring terminal plates and damage to the remote control cord due to problems in the connecting direction of the terminal plates.

Embodiment Hereinafter, a remote controller for electrical equipment according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a remote control case showing how a remote controller for an electrical device is used in an embodiment of the present invention. In FIG. 1, an electrical insulating board 11 is a printed circuit board 1.
In order to cover and insulate the live parts of 6, it is fixed to a remote control (hereinafter referred to as remote control) case 19 together with a printed circuit board 16. 1
Reference numerals 2 and 13 designate terminal boards for connection, which are fixed to the printed circuit board 16. And terminal boards 12, 13 for connection
is provided so as to be located in the opening 17 of the electrically insulating plate 11, and the terminal plates 14 and 15 of the remote control cord 18 are further connected. 21
1 is a cut-and-raised shape in which one side of the opening 17 of the electrically insulating board 11 is cut and raised. 22 is a cut-and-raised part, and as shown in FIG.
3. Two adjacent corners of each are cut and raised. The cut-and-raised portion 21 of the electrical insulating plate 11 is arranged opposite to the cut-and-raised portion 22 of the connection terminal plates 12 and 13. Reference numeral 20 denotes a back cover, which is fitted into the remote control case 19.

FIG. 2 is a cross-sectional view of the remote control case showing the usage state of the remote controller for electrical equipment according to the embodiment of the present invention. As is clear from the figure, the electrical insulating board 11 is connected to the printed circuit board 16.
The cut-and-raised portion 22 of the wiring terminal board 13 and the cut-and-raised portion 21 of the electrical insulating plate 11 are shown to be opposite to each other.

As described above, according to this embodiment, the wiring connection of the remote control cord 18 by a construction worker during equipment installation is regulated by the cutting and raising 21 of the electrical insulating board 11, and cutting and raising with respect to the terminal boards 12 and 13 for connection. The terminal plates 14 and 15 cannot be connected from the 21 side, that is, from the left side in FIG. Also,
The connection of the terminal plates 14 and 15 to the wiring terminal plates 12 and 13 from the vertical direction in FIG. Cannot connect. Therefore, terminal plate 1
4 and 15 can be connected to the wiring terminal boards 12 and 13 only from the right side in FIG. 1, and it is possible to prevent wiring connection problems due to carelessness of the construction contractor.

In other words, the terminal plate 14 is connected to the terminal plate 12 for connection.
When connected from the lower left in FIG. , since the terminal plates 14 and 15 cannot be connected from the left side in Figure 1, the remote control cord 18 is connected to the connection terminal plate 1.
2 and 13 to the left to prevent it from being caught between the remote control case 19 and the back cover 20.

In addition, in this embodiment, the terminal plate 12 for connection,
The cut and raise 22 of No. 13 is a part of two adjacent corners as shown in FIG. The terminal boards 12 and 1 are continuously cut and raised up to the upper left corner and the lower left corner, respectively.
It goes without saying that the top and bottom sides of 3 may be cut up.

Effects of the Invention As described above, according to the present invention, an opening is provided for protruding a plurality of wiring terminal boards made by cutting and raising two adjacent corners, and the openings are formed by cutting and raising the wiring terminal board. By installing an electrical insulating board with one opposing side cut out, it is possible to prevent wiring connection problems due to carelessness on the part of the construction contractor, and prevent equipment malfunctions and breakdowns due to short circuits between wiring terminal boards and damage to remote control cords. can be prevented. In particular, the present invention achieves the above-mentioned effects by cutting and raising the electrically insulating board, so it is inexpensive, does not reduce the workability of installing the electrically insulating board, and is extremely effective in practice.
