Abstract
The utility model relates to a combined safety plug and a socket. The combined safety plug and the socket is composed of a plug, a socket, an inserting rod, and a metal sheet with a contact. An insulation inserting rod is respectively arranged on both sides of the plug. Both sides of the jack of the socket are provided with two jacks. A metal sheet is arranged below the jack. One end of the metal sheet is provided with an insulation sheet. The other end of the metal sheet is provided with the contact. A fulcrum and a tension spring are arranged below the metal sheet. The live wire of an electric wire is connected to the metal sheet. A ground wire is connected to the metal base of the jack. Because the live wire of a power supply is not directly connected to the base in the jack, electric shock accidents can not occur when an iron nail or other metal is inserted into any hole of four holes. When the plug is inserted, the insulation end of the metal sheet is pressed by one insulation rod. The contact end is lifted and is communicated with a contact below the base in the jack. Thus, electricity is achieved for the plug. Because the lower end of the insulation rod forms an inverse sawtooth shape. When inserted downwards, the plug is clamped by edges on both sides of the socket. Thus, the plug can not be released.
Description
The utility model relates to a kind of electrotechnical apparatus, a kind of attaching plug of family expenses more precisely, socket.
Along with the raising of living standards of the people, the owning amount of household electrical appliance increases day by day, and Electrical Safety is the topic that people are concerned about.Because increasing of plugs and sockets, electric shock accidents often have the example that children from getting electric shock takes place also of common occurrence, children's innocence is joyful, inserts the large percentage that causes the accident in the socket with iron nail.Though a lot of safety plug socket inventions are arranged at present, a lot of because of complex structure, the cost height can not be accepted by factory or family.
The purpose of this utility model is: provide plug a kind of simple in structure, with low cost, safe and reliable, socket.
The purpose of this utility model realizes with following method: plug: respectively increase by one in original plug copper sheet both sides and thoroughly do away with the edge inserted link, the plunger end outside becomes zigzag, is convenient to can be blocked by socket after plug inserts, and is difficult for deviating from.Socket: increase by two jacks in former receptacle sockets both sides, one sheet metal is housed under one of them jack, above the sheet metal end topped insulating trip, the other end has a hard contact, one fulcrum is arranged below the sheet metal, below one end of contact an extension spring is arranged, sheet metal is the low state of the high tip side of insulating end when not having external force, the live wire of electric wire is connected on the sheet metal, on the former jack metab of top, contact, a contact is housed also, two contacts are corresponding.The ground wire of power line is connected on another jack metab.In the socket both sides two holes are arranged, button is housed in the hole.
Advantage of the present utility model:,, electric shock accidents can not take place so insert in any hole in four holes with iron nail or other metals because the live wire of power supply directly is not connected on the interior metab of jack.When plug inserts because wherein an insulating bar is depressed the sheet metal insulating end, lift on the tip side with jack in contacting under the metab, in the plug.Because two insulating bar lower ends become zigzag, to insert following time and lived by the checkpost, hole of socket both sides, plug can not deviate from.
Below in conjunction with accompanying drawing the utility model is further elaborated:
Accompanying drawing 1 is the utility model plug construction schematic diagram;
Accompanying drawing 2 is the utility model socket schematic diagram.
Referring to Fig. 1, in plug 1 copper sheet 2 both sides, respectively have one to thoroughly do away with edge inserted link 3, the plunger end outside becomes zigzag 4.Referring to Fig. 2,, two jacks 7 are arranged in socket 5 jacks 6 both sides, one sheet metal 8 is housed under one of them jack, above the sheet metal, an end topped insulating trip 9, the other end has a hard contact 10, a fulcrum 11 is arranged below the sheet metal, below one end of contact an extension spring 12 is arranged, sheet metal is not when having external force, be the low state of the high tip side of insulating end, the live wire 13 of electric wire is connected on the sheet metal, on the jack metab of top, contact, it is corresponding that 14, two contacts, a contact also are housed.The ground wire 15 of power line is connected on another jack metab 16.In the socket both sides two holes 17 are arranged, button 18 is housed in the hole.Using method: when plug insertion socket because wherein an insulating bar is depressed the sheet metal insulating end, lift on the tip side with jack in contacting under the metab, in the plug.Because two insulating bar lower ends become zigzag, to insert following time and lived by the checkpost, hole of socket both sides, plug can not deviate from.In the time of need pulling the plug out of the socket, leave the hole and get final product by advancing sawtooth that two buttons make insulating bar.
