JPH0714390U - Indoor electrical wiring Prevent miswiring and check buzzer - Google Patents

Abstract

(57) [Summary] [Purpose] The present invention prevents incorrect wiring, equipment damage, and electric leakage during electrical wiring work, and enables reliable electrical work regardless of experience. [Constitution] The present invention comprises a dry battery type buzzer, a crocodile clip, a volume control, a dry battery, and a clip, and prevents miswiring, short circuit and electric leakage depending on the presence or absence of the buzzer sound.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention can prevent miswiring in electric wiring work and prevent leakage and damage to equipment.

[0002]

[Prior art]

 I depended on my intuition and experience.

[0003]

[Problems to be solved by the device]

 Skilled electricians are aging, and many of them are technically inexperienced, resulting in frequent miswiring, equipment damage, and electric leakage. It prevents the above accidents and helps early detection.

[0004]

[Means for Solving the Problems]

 This invention uses a battery-powered buzzer for 1.5V, and connects it to a buzzer such as an outlet, a switch, and lighting wiring, and determines whether there is sound or not, whether it is normal or abnormal.

[0005]

[Action]

 The buzzer sounds by shorting the wiring of lights, switches, outlets, etc.

[0006]

【Example】

 Embodiments will be described below with reference to the accompanying drawings. 1) is a miswiring prevention buzzer body 2) is a buzzer 3) is a dry battery 4) is a connection part 5) is a lead wire 6) is a crocodile clip 7) is a clip 8) is a chain 9) is a volume volume and above

A buzzer sounds by fitting alligator clips.

Example: At the end of indoor electrical work for a general household 40A5 circuit. First, connect the plus and minus buzzers to one circuit of the distribution board. If the buzzer does not sound, it is normal. If the buzzer sounds, it is abnormal. Second, if the first circuit is normal, connect the plus and minus wires. Do the same from 1 to 5 circuits. With the above work, short-circuit prevention of indoor wiring is completed.

It is normal for the outlet wiring to connect the positive and negative wires of the buzzer to the black and white wires of the outlet wiring, and the buzzer sounds. For light wiring (without switch), perform the same work as the case. It is normal if the buzzer sounds. For switch wiring, connect the plus and minus wires of the buzzer to the switch wire and short the light wire. It is normal if the buzzer sounds.

[0010]

[Effect of device]

 As mentioned above, the indoor wiring miswiring, short circuit and leakage prevention buzzer of the present invention can be used for electrical work regardless of experience, without miswiring, and it is safe and the entire building can be inspected in about 10 minutes. You can easily finish.
