Abstract

The utility model discloses a convertible plug for multiple-purpose electric source, which makes a grounding pin of the three-pole plug of the national standard omitted, but makes one or a plurality of two-pole plug sockets installed in the plug casing; each wiring foot respectively connects with the corresponding pin in the plug casing, and thus, the three-pole plug socket can change to a plurality of two-pole plug sockets. The utility model has the advantages of simple structure, low cost, and convenient usage.

Description

Convertible plug for multiple-purpose electric source

The utility model relates to a kind of attaching plug, particularly a kind of multipurpose plug that self has an above socket.

Multipurpose plug of the prior art is that a two-wire plug and plural two pole sockets combine, and this two-wire plug has two standard pins that are parallel to each other.The often earth-free line of present a lot of electrical equipment and use a standard two-wire plug, but many supply sockets have three pole sockets of ground wire often, the live wire and the neutral receptacle of this socket are not parallel, and the standard two-wire plug of making can't use.

The purpose of this utility model is to provide a kind of three utmost points, two utmost points conversion multipurpose plug that three pole sockets can be transformed to standard two pole sockets that can overcome above-mentioned shortcoming in the prior art.

The utility model is achieved in that a kind of multipurpose power source changeover plug, form by shell and pin, pin is the bullion sheet, two pins are perpendicular to shell, two pin interplanars have an angle between 45 °～90 °, with the side one group or several groups of standard two utmost point sockets are arranged respectively on shell, and all there is the pair of metal contact every group of socket inboard, one of them hard contact links to each other with a pin, and another hard contact links to each other with another pin.

The utility model is improved because of the three-terminal polarized plus plug to GB1002-80 standard in the prior art, without its earth pin, and have standard two utmost point sockets in other sides of plug body, the plug inside correspondence position is equipped with hard contact, each hard contact links to each other with a pin, so original three pole sockets can be converted to one or several two pole socket, two-wire plug can be used.

Fig. 2 is a schematic top plan view of the present utility model

1-shell 2-pin 3-socket 4-elastic sheet metal wherein

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As Fig. 1, shown in Figure 2, shell (1) is cuboid, pin (2) is the bullion sheet, form the angle between 45 °～90 ° between two pins (2), two pins (2) are all vertical and insert shell, behind 90 ° of the root bendings of pin (2), be fixed on the shell with screw, a pair of socket (3) is all arranged both sides up and down at shell (1), there is one group of elastic sheet metal (4) socket (3) inboard, after elastic sheet metal (4) is fixed on the sheet metal with rivet, link to each other with pin (2) riveted joint by this sheet metal again, or directly be fixed on the shell (1), link to each other with pin (2) with lead again with screw, still have one group of socket (3), inboard to have one group of elastic sheet metal (4) to be fixed on shell (1) at the back side of plug and be connected with pin (2).Pin (2) is inserted in two holes of three pole sockets during use, and then two-wire plug inserted in two utmost point jacks on the utility model can make electrical appliance, in this example, be provided with three group of two utmost point jack altogether.

Claims

1, a kind of multipurpose power source changeover plug, form by shell (1) and pin (2), pin (2) is by pin positional alignment in the three-terminal polarized plus plug in the GB GB1002-80 standard, it is characterized in that: have one group of two pole socket socket (3) on the shell (1), socket (3) is inboard, pair of metal sheet (4) is equipped with in shell (1) inside, one of them sheet metal (4) links to each other with electric conducting material with a pin (2), and another sheet metal links to each other with electric conducting material with another pin (2).

2, a kind of multipurpose power source changeover plug as claimed in claim 1 is characterized in that: one group of two pole socket also is housed on shell (1).
