Abstract

The utility model relates to a multi-purpose single-phase power plug, comprising a shell, a two-pole inserting piece. A rotating shaft with the two-pole inserting piece in the shell is connected with the shell through a baffle plate which is vertically fixed on the inner side of the shell and a hole on the bottom of the shell. The shaft with the two-pole inserting piece of the multi-purpose single-phase power plug of the utility model can rotate, and thus the utility model can be suitable for the sockets with jacks in different angles. Additionally, the ground-line pin part of the utility model can be take off form the plug, or the ground-line pin can be taken off form the shell without damaging the structure. Thus, the mutual transformation of a two-pin plug and a three-pin plug can be realized. Consequently, the propose of one head with a plurality of functions can be realized, and the convenience is brought to the user.

Description

JMultipurpose single-phase power plug

The utility model belongs to attaching plug, is specifically related to a kind of single phase poaer supply plug of using more.

Existing family, unit use small-power electrical equipment plug, mostly adopt 250 volts 6 amperes or 10 amperes two latches and the single phase poaer supply plug of three latches, are fixed between its latch and the shell.In actual use, can usually run between the plug and socket is not lucky supporting problem.Mostly use Multi-purpose power socket to solve at present, but, still can occur closing actual conditions such as useless such as the not enough and another kind of sky again of certain receptacle sockets because plug does not have very variation.In addition, use Multi-purpose power socket, can make on the one hand to produce between the electrical equipment to interact, on the other hand, its price is expensive.

The purpose of this utility model provides the single phase poaer supply plugs of using that can be fit to multiple difformity receptacle sockets more, to solve between plug and the socket problem of the lack of coordination mutually.

For reaching above-mentioned purpose, comprise the two poles of the earth inserted sheet and plug body with the single phase poaer supply plug more than of the present utility model, the rotating shaft of band the two poles of the earth inserted sheet is arranged in the plug body, between rotating shaft and the plug body by being connected with the hole of hole and plug body bottom on the baffle plate with holes of the inboard vertical fixing of shell.

The utility model is used the single phase poaer supply plug more, has the gear of the limited bit platform in both sides in the rotating shaft, intermeshes between the gear, or is with shift fork in its rotating shaft, connects by the declutch shift shaft that is fixed on outer casing bottom between the shift fork.

The single phase poaer supply plug of using of the present utility model, its rotating shaft core and the two poles of the earth inserted sheet axis deviation distance are 0.8-1.2mm more.

Use single phase poaer supply plug of the present utility model more, be fixed on the ground wire contact pin in the housing in its housing in addition.

The single phase poaer supply plug of using of the present utility model more, can also comprise the ground wire latch, the ground wire plug part that housing constitutes, sheet metal with holes is arranged on the ground wire latch, fix ground portion and many between ground wire inserted sheet and the housing with fixing by screw or spring pivot between the single phase poaer supply plug by perforated metal sheet and housing bottom on the ground wire latch.

The single phase poaer supply plug of using of the present utility model more, the screw or the spring pivot of fixed power source plug and ground wire latch part, the one end contacts with ground wire contact pin, and the other end contacts with the ground wire latch.

How of the present utility model can also have the ground wire latch with the single phase poaer supply plug, and ground wire latch and housing are fixed, or are fixed on the bottom of shell between ground wire latch and the shell by sheet metal with holes on the latch.

The single phase poaer supply plug of using of the present utility model also has ground wire contact pin more in its plug casing, be connected with conductor in the ground wire contact pin, and the other end of conductor contacts with the ground wire latch.

Because it is of the present utility model many with the rotating shaft that band the two poles of the earth inserted sheet is arranged in the single phase poaer supply plug, therefore, only at rotating shaft, the two poles of the earth inserted sheet that is fixed in the rotating shaft is rotated thereupon, like this, make plug can be fit to the socket of different angles jack, adopt both sides limited bit platform sector gear rotating shaft or shift fork rotating shaft, can make the two poles of the earth inserted sheet realize that the synchronous backward think of is moving on the one hand, on the other hand, spacing platform makes controlledization of inserted sheet rotational angle.Many with adopting spring pivot or screw between single phase poaer supply plug the two poles of the earth inserted sheet part and the ground wire plug pin portion branch, the ground wire plug part can be taken off from the two poles of the earth plug, to realize two latch plugs and three latch plug and to transform mutually, adopt the two poles of the earth inserted sheet and the use single phase poaer supply plugs of ground wire latch on same housing more, the rotating rotating shaft of band the two poles of the earth inserted sheet is also arranged in its housing, therefore, also can make the two poles of the earth inserted sheet change the socket that angle is fit to the difformity jack, ground wire contact pin is arranged in it, ground wire contact pin contacts with the ground wire latch by conductor, fix with perforated metal sheet and housing bottom on it owing to the ground wire latch again, so when unloading the ground wire latch, can not damage plug and realize that two latch plugs and three latch plug exchange, simultaneously, two kinds of shapes that can make the ground wire latch are that ground wire inserted sheet and ground wire inserting column exchange easily, make of the present utility modelly many really to have accomplished the many usefulness of one " head " with the single phase poaer supply plug, thereby bring convenience to users.
