Abstract
The utility model relates to an alarm power plug for charged ground wire, which comprises an existing power plug. The utility model is characterized in that a neon tube (7) is arranged in a casing body (2) of the power plug and is encapsulated with a photoresistor; both ends of the neon tube (7) are respectively connected with the ends of a relative zero wire (4) and a ground wire (3), and the photoresistor (7) is connected to the trigger electrode of a silicon controlled rectifier (8) of which the anode is connected with a buzzer (5) and a light emitting diode (6) in series. When high voltage exists on the ground wire of the power plug, the utility model can give an alarm in an acoustic and optical form, therefore, accidents threatening the safety of life can be avoided.
Description
The utility model relates to a kind of electric component, particularly relates to a kind of ground wire electrification warning attaching plug.
At present, common attaching plug has a housing, and three inserted sheets are housed, and an inserted sheet earth connection is wherein arranged, and this pin function is single, only is used for the socket of electrical equipment and power supply is coupled together.The old-fashioned building of some of China does not mostly have earth connection, and the also defective of earth connection arranged, and this can constitute a threat to people's life security, in fact, ground wire electrification or intermittently charged situation often occur, even causes casualty accident.
The purpose of this utility model provides a kind of ground wire electrification warning attaching plug, and it can remedy the above-mentioned deficiency of existing power supply plug.
The utility model comprises an existing attaching plug, it is characterized in that in the housing of plug, neon tube being housed, it and photo resistance are packaged together, the two ends of this neon tube connect Relative Zero dotted line and ground terminal respectively, photo resistance is connected on the silicon controlled trigger electrode, silicon controlled anode series one buzzer and light-emitting diode.
Can report to the police with the form of sound, light when there is high voltage in the utility model on the ground wire of supply socket, therefore can avoid the accident of threat to life safety to take place.
Below by embodiment and description of drawings the utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is its circuit diagram.
The utility model comprises an existing attaching plug, it has a housing (2), this housing (2) is equipped with three inserted sheets (1), it is characterized in that in housing (2), being equipped with neon tube (7), it and photo resistance are packaged together, the two ends of this neon tube (7) connect Relative Zero dotted line (4) and ground wire (3) respectively, and photo resistance (7) is connected on the trigger electrode of controllable silicon (8), anode series one buzzer (5) of controllable silicon (8) and light-emitting diode (6).
When using the utility model, it is inserted in the supply socket, its three inserted sheets (1) respectively with socket in L, N be connected with ground terminal, and Relative Zero dotted line (4) be connected to the earth or running water pipe etc. locate, this place's current potential is considered as zero.When the current potential difference between ground wire (3) and the Relative Zero dotted line (4) reaches certain level (for example 80V), then neon tube is just luminous above its starting voltage, the photo resistance resistance reduces, make controllable silicon (8) conducting, thereby the circuit communication that makes buzzer (5) and light-emitting diode (6) sends sound, light is reported to the police, with the caution user.
Claims (1)
1. ground wire electrification warning attaching plug, comprise an existing attaching plug, it is characterized in that in the housing (2) at plug neon tube (7) being housed, it and photo resistance are packaged together, the two ends of this neon tube (7) connect Relative Zero dotted line (4) and ground wire (3) end respectively, photo resistance (7) is connected on the trigger electrode of controllable silicon (8), anode series one buzzer (5) of controllable silicon (8) and light-emitting diode (6).
