CN2117655U - Shape adapting multifunctional plug - Google Patents

Abstract

The utility model relates to a shape adapting multifunctional plug composed of a box body, a plug pin seat and a box cover, wherein, the upper part of the box cover is provided with a lamp slot; a neon glow lamp is arranged in the lamp slot; one end of the neon glow lamp is contacted with the box body; a conductive wire which extends from one end is connected with a grounding wire; a grounding plug pin can be dismounted; the plug pin of a null line and the plug pin of a fire wire are changed into a = shape from an inverted shape of Chinese character 'ba', so a single-phase two-pole socket can be plugged. Based on the same principle, the single-phase two pole socket can be changed into a three-pole single-phase plug. The utility model can cause operators to utilize the neon glow lamp for displaying whether the electrical leakage phenomenon of an electrical appliance occurs. Shape adapting between electrodes is not limited by the socket, so the formal contradictory of plugs and sockets is solved; the utility model can be easily used.

Description

Shape adapting multifunctional plug

The utility model relates to a kind of phase enantiotropy functional universal attaching plug.

All two utmost points and three-electrode power plug all do not have the electric leakage detecting function, and electrical equipment shell electric leakage occurs and causes electric shock accidents.Single-phase two-wire plug only mates with two pole sockets, and three-terminal polarized plus plug only mates with three pole sockets, each other can not be general.

The purpose of this utility model is to provide a kind of electrical equipment of surveying whether to leak electricity to the public, two utmost points and three-terminal polarized plus plug be the attaching plug of conversion mutually.

The utility model can be realized by following principle: it is that neon glow lamp one end joins with earth connection and grounding leg that electric leakage is surveyed, an end in contact box body, and box body resistance is greater than 3 megaohms.As the electric appliance casing electric leakage, constitute loop inductance by earthing of casing line, neon glow lamp, box body and human body, the neon lamp build-up of luminance.The electrode change is that the pin of earth electrode is fixed on the pedestal, and the pin of zero line and live wire also is fixed on the pedestal simultaneously.Unscrew hold-down screw, conversion is the pin position once, is down " eight " font and arranges and to become "=" font and arrange, and lays down grounding pin, two-wire plug.

Advantage of the present utility model can make the operator before touching electrical equipment, knows electric leakage by neon lamp is luminous.This is to the protection personal safety, prevents electrical equipment overload and the damage that causes has prediction effect; The electrode change is not subjected to the limitation of socket type, has solved the plug of electric equipment and the contradiction between the socket.

Detail of the present utility model provides from accompanying drawing and embodiment.

The utility model is by box body 1, and connector assembly 2, lid 3 are formed.Box body 1 is the garden tubular, on the tube light trough 4 is arranged, and light trough 4 has through hole, and light trough 4 is placed with neon glow lamp 5, and neon lamp one end contacts with box body 1, and the lead of the other end is connected with earth electrode 11 with earth connection through the through hole of light trough 4.There is individual garden platform 7 in central authorities in the box body 1.There is screw 8 at platform 7 centers in garden.Box body 1 inwall has three garden ring recess 9, and the lower edge inwardly has three breach 10 every 120 degree.Connector assembly 2 shapes are garden sheets, open three and are the small through hole 17 that the isosceles triangle base angle is 55 degree arrangements.Pin sheet 11,12,13 is " 7 " font, and all there is through hole the termination.Be fixed on the connector assembly 2 with M3 screw 14.Screw 14 is the short end through holes that pass the pin sheet, and the through hole 17 on the connector assembly 2 is connected with thereafter little copper sheet 15, and little copper sheet 15 has internal thread.Copper sheet 15 behind the pin 11 is connected with lead, the earth connection of neon lamp, and the little copper sheet 15 that is connected with pin 12,13 is connected with live wire with zero line respectively.As want two-wire plug, and back out screw rod 14, lay down pin 11, pin 12,13 is rotated in crossed grooves, " eight " word arrangement of falling of pin 12,13 is become parallel "=" word arrangement, tighten screw rod 14, cover lid 3.As changing three-terminal polarized plus plug into, set up pin 11, tighten screw rod 14, rotate pin " eight " word arrangement played the part of down in "=" word, cover lid 3.Socket 2 central authorities have garden through hole 16 to cooperate with the garden platform 7 of box body 1 central authorities.Pin base 2 is embedded in the box body 1.Also the lead of copper sheet 15 with external wire, neon glim lamp can be installed earlier, box body 1 and pin base sheet 2 are injected into one.Lid 3 is a garden sheet, is opening 18, one " one " words of groove groove, two crossed grooves with the relevant position of the through hole 17 of pin base.Angle between crossed grooves two grooves is 150 degree.Cover plate 3 centers have fixing hole 19, and fixing hole 19 is up big and down small.Pin sheet 11,12,13 passes flat recess and crossed grooves.Screw 20 is lid 3 fixedly.Lid 3 outers inwardly have 3 breach 21, with the breach 10 relative lids of box body 1, conveniently to take off lid.

Claims (1)

1. Phase enantiotropy functional universal attaching plug, comprise box body 1, pin 11,12,13, with lid 3, it is characterized in that neon glow lamp 5 on box body 1, an end in contact is greater than earth connection on 3 megaohm box bodys, 1, one termination, lay down pin 11, make pin 12,13 become "=" font, or pin 11 is set up, make pin 12,13 that "=" font is changed into down " eight " font by falling " eight " font.
