Abstract

Disclosed are a blind man plug socket and an adaptor, which comprises a plug, a socket and an adaptor. The plug is structurally characterized in that a cylinder (2) under a rigid insulating cylindrical handle (1) is provided with 2 to 3 copper rings (4) (5) (6) with arc surfaces, electric wires (8) are connected with the copper rings through the handle (1), and the end portion of the cylinder is formed into a semi-sphere shape. The socket is structurally characterized in that a hole (10) with a slope-shaped hole opening (11) is disposed inside an insulating box body (9), copper contact sheets (12) are perpendicularly disposed inside the hole, electric wires (13) are respectively connected with the copper contact sheets (12), and each pair of the copper contact sheets are connected through conducting wires (14). The adaptor is structurally characterized in that the upper portion of the plug (15) is provided with the socket (16). The utility model overcomes the difficulties of inconvenience and insecurity when blind men use plugs and sockets sold in the current market. In addition, the plugs on existing appliances are alteration-free, thereby achieving simple operation and low costs.

Description

Blind person's plugs and sockets and adapter

Technical field

The utility model relates to electrical field, a kind of more precisely plugs and sockets of blind person's special use.

Background technology

At present, commercially available plugs and sockets is various in style, but all is that plug is copper sheet or the copper bar that protrudes in appearance, socket is a shrinkage pool, and these products have no fastidious part concerning the people that eyesight perfects, but concerning the blind person, there is potential safety hazard, because of the blind person will touch jack with hand earlier with plug insertion socket, again plug is inserted, as long as copper sheet one touches live wire, copper sheet is just charged, is gently then shocked by electricity because of carelessness slightly, and is heavy then electric shock accidents takes place.So far do not see the plug that has blind man to use, socket product and patent are come out.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned drawback, and a kind of plug, socket and adapter that safely, makes things convenient for blind man to use is provided.

The purpose of this utility model adopts following technical measures to realize: the utility model mainly is made up of plug, socket, adapter.It is characterized in that: described plug: be shaped on the copper ring that 2-3 surface becomes circular arc on the insulative cylinders body of hard, ring joins with fire, zero line or fire, zero, ground wire respectively, and it is hemispherical that the cylinder end becomes.Described socket: in the box body of insulation a hole is arranged, the aperture is a domatic, is convenient to plug and inserts, and vertically is shaped on the copper contact chip of circular arc concave surface in the hole.Described adapter: on plug, be shaped on the commercially available socket in three holes or two holes, when the blind person uses conventional plug, earlier plug inserted the socket of adapter upper end, again with the insertion of the plug adapter under the utility model socket.

Remarkable result of the present utility model: solved present blind person and used commercially available plug, socket inconvenience, dangerous deficiency need not changed the plug on the existing electrical equipment, and easy and simple to handle, cost is lower.
