Embodiment

As shown in Figures 1 and 2, a kind of plug, comprise body 110 and the conducting rod 120 that is installed on body 110, body 110 comprises the first noumenon 112, the second body 114 and the 3rd body 116, the first noumenon 112 is removably connected with the second body 114, and the 3rd body 116 is removably connected with the second body 114 with the first noumenon 112.On the first noumenon 112, the second body 114 and the 3rd body 116, be respectively equipped with conducting rod, the first noumenon 112 is provided with the first conducting rod 122, the second bodies 114 and is provided with the second conducting rod 124, the three bodies 116 and is provided with the 3rd conducting rod 126.The first conducting rod 122 is threaded with the first noumenon 112, and the second conducting rod 124 is threaded with the second body 114, and the 3rd conducting rod 126 is threaded with the 3rd body 116.

Body 110 comprises the first noumenon 112, the second body 114 and the 3rd body 116.

The material that the first noumenon 112, the second body 114 and the 3rd body 116 can adopt macromolecule polymer material etc. to have electrical insulating property is made.Body 110 also can adopt upper shell and lower house, and upper-lower casing is fixed with bolt, within internal circuit is located at housing, has both played insulating effect, again escapable cost.

The first noumenon 112 is connected with the second body 114, and the 3rd body 114 is connected with the second body 114 with the first noumenon 112.

The first noumenon 112 and the second body 114 can be by mutual socket connections, make the first noumenon 112 and the second body 114 detachable fixing, also can establish by mutual card, make the first noumenon 112 and the second body 114 mutually block and establish, to realize the first noumenon 112 and the fixing object of the second body 114.In the present embodiment, the first noumenon 112 and the mutual socket connection of the second body 114, the 3rd body 116 can with the first noumenon 112 and the second body 114 socket connections.

In the present embodiment, the first noumenon 112, the second body 114 and the 3rd body 116 all can be provided with conductive insert 130, in the first noumenon 112, be provided with the first conductive insert 132, in the second body 114, can be provided with the second conductive insert 134, in the 3rd body 116, also can be provided with the 3rd conductive insert 136, the 3rd body 116 is provided with conducting connecting bar 140, and conducting connecting bar 140 one end can be connected with the 3rd conductive insert 136 of the 3rd body 116, and the other end is connected with ground wire.Wherein, the quantity of conducting connecting bar 140 can be two.

Be understandable that, at the first noumenon 112 and the second body 114, also can offer slot, conductive insert 130 is located at slot bottom, and slot and conducting connecting bar 140 match, within conducting connecting bar 140 is inserted in slot.So, can make the 3rd body 116 be fixed on the first noumenon 112 and the second body 114, also prevent that conducting connecting bar 140 from causing poor electric contact because rocking with other reasons.

On the first noumenon 112, the second body 114 and the 3rd body 116, be respectively equipped with conducting rod 120, the first noumenon 112 is provided with the first conducting rod 122, the second body 114 is provided with the second conducting rod 124, the 3rd body 116 is provided with the 3rd conducting rod 126, the first conducting rod 122 is threaded with the first noumenon 112, the second conducting rod 124 is threaded with the second body 114, and the 3rd conducting rod 126 is threaded with the 3rd body 116.In addition, the first conducting rod 122 is electrically connected to the first conductive insert 132, and the second conducting rod 124 is electrically connected to the second conductive insert 134, and the 3rd conducting rod 126 is electrically connected to the 3rd conductive insert 136.So, while not having sufficient space to be convenient to plug on socket to plug, conducting rod 120 can be screwed out in draw-in groove, so that conducting rod 120 exposes the length long enough of body 110, be convenient to be inserted on socket, easy to use.

Above-mentioned plug, body 110 comprises the first noumenon 112, the second body 114 and the 3rd body 116, the first noumenon 112 is removably connected with the second body 114, the 3rd body 116 is removably connected with the second body 114 with the first noumenon 112, the first noumenon 112, the second body 114 and the 3rd body 116 are respectively equipped with conducting rod, and the conducting rod of the first noumenon 112, the second body 114 and the 3rd body 116 is threadedly connected to respectively corresponding body.So, when needs two-pin plug, the 3rd body 116 can be extracted from the first noumenon 112 and the second body 114, be realized the object that 3-phase plug is become to two-pin plug, easy to use.When some sockets do not have sufficient space that plug is plugged, conducting rod 120 is screwed out from body 110, make conducting rod 120 expose body 110 long enoughs, be convenient to be inserted on socket, easy to use.

Refer to Fig. 3, therein in an embodiment, conducting rod 120 comprises and stretches out the conductive base pin 123 of the first noumenon 112, the second body 114 and the 3rd body 116 and the knob 125 extending from conductive base pin 123 one end, and knob 125 is provided with external screw thread.In the first noumenon 112, the second body 114 and the 3rd body 116, can be provided with draw-in groove, draw-in groove is provided with internal thread, and the knob of the first conducting rod 122, the second conducting rod 124 and the 3rd conducting rod 126 is threadedly connected to the draw-in groove of the first noumenon 112, the second body 114 and the 3rd body 116 respectively.The knob 125 of the conducting rod of the first noumenon 112, the second body 114 can be connected with the 3rd conductive insert 136 with the first conductive insert 132, the second conductive insert 134 respectively.

Refer to Fig. 3, in an embodiment, knob 125 is frustum therein, and knob 125 radially increases successively towards the direction size of conductive base pin 123, and draw-in groove and knob 125 match.So, when using plugs and sockets, by larger power, can prevent from, because larger power makes screw thread stripped thread, having increased the useful life of socket.

Refer to Fig. 3, in an embodiment, the junction of conductive base pin 123 and knob 125 is provided with support division 127 therein, and the size of support division 127 is greater than draw-in groove radial dimension.When plug insertion socket, support division 127 is held in body 110, can further prevent because making more energetically screw thread stripped thread.

The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
