Abstract

PROBLEM TO BE SOLVED: To prevent the indication on the upper surface of a breaker such as letters and marks, even in the case that it is formed by means of printing or the like, from being damaged by being scraped down by a shield plate by forming small protrusion on the upper face of a case so as to make a clearance between the indication surface for print or the like and the shield plate. SOLUTION: Provided to the surface of the top face 1 of a breaker case 3 that is to be a catching part of a shield plate 2 of a distribution board is an indication surface (indication surface for print or the like) 1a on which letters, marks and the like designating such as a neutral pole, a power source side, a load side are formed by means of printing or the like. In this case, the top face 1 is equipped with small protrusion 4; the small protrusion 4 catch a shield plate 2 of a distribution board on the top face 1 of the breaker case 3 so as to form a clearance between the indication surface 1a for print or the like and the shield plate 2. Thereby, the letters, marks and the like on the indication surface 1a for print or the like are prevented from being damaged by stopping the shield plate 2 from coming into contact with the indication surface 1a for print or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit breaker suitable for use in a distribution / distribution panel.

[0002]

2. Description of the Related Art As shown in FIGS. 4 and 5, a distribution / distribution panel is provided with a shield plate 23 from which a handle portion 22 of a breaker 21 can be exposed from the viewpoint of protecting a charged portion of a breaker terminal and the like and preventing danger. It is usually installed. Therefore, the characters for displaying the neutral pole, power supply side, load side, AA, 100 V, 200 V, etc., which are printed or affixed to the surface of the upper surface 24 of the breaker 21 serving as the receiving portion of the shield plate 23 , The symbol 25, etc., are separated and the shield plate 23 is vibrated by opening and closing the door of the switchboard or operating the handle 22 of the breaker 21 to rub and damage the character, symbol 25, etc. There was a problem that took time to confirm.

[0003]

As a solution to this problem, there is a method of directly engraving characters and symbols on the upper surface 24 of the breaker 21. However, in this case, various breakers are manufactured using the same case due to the difference in the internal mechanism, so that it is not possible to cope with the problem. Therefore, even if characters or symbols are displayed on the upper surface 24 of the breaker 21 by printing or the like, the breakers 21 are provided to provide a breaker that is not liable to be damaged by being rubbed by the shield plate 23.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The present invention is directed to a printed or similar display surface provided on an upper surface portion of a breaker case serving as a receiving portion of a shield plate of a distribution / distribution panel, and the shield plate. A means for forming a gap between the shield and the shield is provided on the upper surface of the case. It can be done by setting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described in detail with reference to FIGS. Reference numeral 1 denotes an upper surface portion of a case 3 of a breaker serving as a receiving portion of a shield plate 2 of a distribution / distribution panel. The surface of the upper surface portion 1 has a neutral pole, a power supply side, a load side, AA, 100 V, 200 V A printing or label affixing or writing display surface (hereinafter referred to as “printing or other display surface 1a”) provided by printing, label affixing, or writing characters, symbols, or the like indicating use or the like is provided. In the illustrated example, "N" indicating the neutral pole is printed and displayed by screen printing or the like.

The upper surface 1 of the case 3 of the above-mentioned breaker
Means for forming a gap between the display surface 1a for printing or the like provided on the upper surface 1 and the shield plate 2 is provided on the upper surface portion 1 side. 1 to 3, a small projection 4 protrudes from the upper surface 1 and receives the shield plate 2 on the upper surface 1 of the case 2. There is no danger that the shield plate 2 will contact the display surface 1a for printing etc. to damage the characters and symbols on the display surface 1a for printing etc. by forming a gap between them. In addition, the small protrusion 4 is a display surface 1 for printing or the like.
One may be provided near a, but a plurality may be provided, or
Even if it is provided apart from the display surface 1a for printing etc., it is essential that a gap is properly formed between the display surface 1a for printing etc. and the shield plate 2,
The installation location does not matter.

[0007]

According to the present invention, as is apparent from the above description, a gap is provided between a display surface such as a printing surface provided on the upper surface of a breaker case serving as a receiving portion of a shield plate of a distribution / distribution panel and the shield plate. By providing the means for forming on the upper surface of the case, there is no danger that the shield plate will contact the display surface such as printing and damage characters and symbols on the display surface such as printing. There is also an advantage that no consideration is required. Further, when the breaker is incorporated in the distribution / distribution board, an accurate display can be made by simple printing or the like. Therefore, the present invention greatly contributes to the industry as a solution to the problem of the conventional breaker.
