Abstract

PROBLEM TO BE SOLVED: To fix foreign matters such as dust causing conduction failure at one place and prevent the occurrence of the conduction failure by sticking one face of a double-coated adhesive tape available on the market at an optional position on the inside face of the cover or case of an apparatus such as a wiring circuit breaker or an earth leakage breaker. SOLUTION: A double-coated adhesive tape 2 is provided on the inner face section of the cover 1 of a wiring circuit breaker with its one adhesive face exposed. When the double-coated adhesive tape 2 is provided on the inner face of a case like on the cover 1 with its one adhesive face exposed, the same effect is obtained. As the method for exposing the adhesive face on the inside face of an apparatus, one face of the wide plate-like double-coated adhesive tape 2 is stuck to the inside face of the apparatus, then it may be partially covered with a cover having a peephole. One adhesive face of the double-coated adhesive tape 2 is partially exposed in the apparatus, foreign matters such as dust entering the apparatus are fixed on the adhesive face provided on the cover 1 or case by the vibration during transportation, and the cause of conduction failure is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit breaker having a contact point such as a circuit breaker, an earth leakage breaker, an electromagnetic contactor, and various relays.

[0002]

2. Description of the Related Art Wiring breakers, earth leakage breakers, electromagnetic contactors, various relays, etc. having contacts are generally known devices which are commercially available, and the present invention is applied to the structure of these devices. This is a structure that has never existed before.

[0003]

In a conventional switch or the like having a contact, foreign matter such as dust that has entered the inside of the device for some reason moves around in the device due to vibration or the like during transportation. If it stops at this point, the conduction of current is hindered, resulting in defective equipment (hereinafter referred to as poor conduction).

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a structure for fixing foreign matter such as dust causing such a conduction failure at a predetermined position and preventing the occurrence of the conduction failure.

[0005]

SUMMARY OF THE INVENTION The present invention is characterized in that a foreign substance such as dust entering a switch or the like having a contact point is attached and fixed. An inexpensive and easy-to-use method for attaching and fixing foreign matter such as dust to the adhesive surface by exposing the adhesive surface of the nameplate / backing plate with an adhesive on the double-sided adhesive tape or the adhesive surface on the inner surface of the device It is.

[0006]

1 to 3 show an embodiment showing the structure of the present invention. The present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention, in which a cover 1 of a circuit breaker for wiring is viewed from the inside of a device. One side of the double-sided adhesive tape 2 attached to the inner surface of the cover is exposed. Also, the double-sided adhesive tape may be attached to the inner surface of the case in the same manner as the cover (not shown).
There is a similar effect.

FIG. 2 shows a second embodiment of the present invention in which the cover 1 'of the circuit breaker is viewed from inside the device. A part of the adhesive surface of the nameplate 3 attached to the surface of the cover is exposed by a hole 4 formed in the cover. In addition, there is a possibility that some of the currently marketed devices and the like have holes drilled for other purposes that happen to match the purpose of the present invention. This is done intentionally for the purpose of blocking.

FIG. 3 shows a third embodiment of the present invention, in which the case 5 of the circuit breaker for wiring is viewed from the cover direction (the opening and closing mechanism and the like are removed). A part of the adhesive surface of the backing plate 6 attached to the back of the case is exposed by a hole 7 formed in the case. In addition, there is a possibility that some of the currently marketed devices and the like have holes drilled for other purposes that happen to match the purpose of the present invention. This is done intentionally for the purpose of blocking.

[0010]

According to the present invention, foreign matter such as dust entering the inside of the device is attached and fixed to the adhesive surface provided on the cover or the case by vibrations during transportation, and the cause of the conduction failure is eliminated. Has an effect. The effect may be maintained until devices such as switches are attached to a switchboard or the like. Further, since the contact structure and the opening / closing mechanism of the device are the same as those of the conventional product, there is no need to change the shape, and the device is provided as an inexpensive structure.

[Brief description of the drawings]

FIG. 1 is an explanatory view illustrating the present invention implemented on an inner surface of a cover of a circuit breaker for wiring.

FIG. 2 is an explanatory view in which the present invention is applied to a name plate portion on a cover upper surface of a circuit breaker for wiring.

FIG. 3 is an explanatory view in which the present invention is applied to a case backing plate portion of a case circuit breaker of a wiring breaker; (Structural components such as terminals, contacts, and opening / closing mechanisms are not shown.)
