Main purpose of the present utility model is to provide a kind of plug of improvement, be meant a kind of plug that to link to each other between the attached electric equipment of automobile and the automobile cigarette lighter jack that is exclusively used in especially, and can be applicable to U.S., Europe vehicle simultaneously, and can optionally change at any time the plug connector end in polarity.

Another purpose of the present utility model is to provide a kind of easy to operate, and same plug can be suitable for various different electric equipments and different electric power polarities, makes single simplification, the plug of practical improvement.

For this reason, the utility model is taked following technical scheme:

A kind of plug of improvement, comprise a pedestal and a plug-in unit, it is characterized in that: described pedestal end plane is provided with elongate slots in order to this plug-in unit of pegging graft, the arrow mark of polarity on an end of this elongate slots is provided with as indication plug-in unit end face, groove inside is provided with two column electric terminals, the power supply that is used separately as the conducting plug-in unit just, negative pole, the outside wall surface of pedestal is provided with a power supply indicator, described pedestal is received slightly turriform in the end of elongate slots makes progress with column, and in two staggered corresponding surfaces of outside, pedestal upper end, be respectively equipped with protruding contact of two arcs and two inverted U-channels, the protruding contact of two arcs wherein, a wherein column that is conducting elongate slots inside is electric by an electrode contact of formation automobile cigarette lighter jack, establish an oblique cone metal cap and an axial elasticity post on the top of pedestal, and another column electric terminal of oblique cone metal cap and the common conducting elongate slots of axial elasticity post inside thus, and form another electrode contact in the automobile cigarette lighter jack; Described plug-in unit is inserted in the elongate slots on the pedestal end plane, one end of plug-in unit connects lead, the front end face of plug-in unit is provided with two jacks, the side one of plug-in unit connects the elasticity tenon that protrudes, on other end flat, be respectively equipped with polarity mark, when plug-in unit is inserted in elongate slots, end supports engaging by the elasticity tenon and make the plug-in unit can strong fix, and make the set arrow mark of elongate slots one end just point to mark on the plug-in unit.

In sum, the utility model is by peg graft the mutually plug of combination of pedestal and plug-in unit, can be applicable to different U.S.s, Europe vehicle, car type simultaneously, and can optionally change the polarity of plug connector terminal at any time, on the structure, each assembly is easy to use through particular design, makes single simplification, have creativity, tool is practical.

The utility model embodiment is described with reference to the accompanying drawings as follows:

Fig. 1 is the utility model three-dimensional appearance schematic diagram.

Fig. 2 is the utility model decomposition texture schematic diagram.

The figure number explanation:

The plug of 10 the utility model improvement, 11 pedestals, 12 elongate slots, 13 arrow marks, 14 indicator lights, 15 contacts, the protruding contact of 16,17 arcs, 18,19 inverted U-channels, 20 metal caps, 21 elasticity posts, 30 plug-in units, 31,32 elasticity tenons, 33 leads, 34,35 jacks, 36,37 polarity marks.

See also shown in Figure 2ly, plug 10 integral body of the utility model improvement are constituted by a pedestal 11 and a plug-in unit 30.

This pedestal 11, be provided with elongate slots 12 in its end plane, in order to this plug-in unit 30 of pegging graft, end in this elongate slots 12 is provided with arrow mark 13, as the polarity on indication plug-in unit 30 end faces, the inside of groove is provided with two column electric terminals 15, the power supply that is used separately as conducting plug-in unit 30 just, negative pole, the outside wall surface of pedestal 11 is provided with a power supply indicator 14, when these two electric terminals, 15 turn-on powers, can luminously indicate, see the global shape of pedestal 11 from outward appearance, system is from the end of elongate slots 12, slightly be turriform with the upwards interior receipts of column, and in two staggered corresponding surfaces of outside, pedestal 11 upper end, be respectively equipped with the protruding contact 16 of two arcs, 17 and two inverted U-channels 18,19, the protruding contact 16 of above-mentioned two arcs, the 17th, a wherein column electric terminal 15 of conducting elongate slots 12 inside, form an electrode contact of automobile cigarette lighter jack, then be provided with an oblique cone metal cap 20 and an axial elasticity post 21 on the top of pedestal 11, and another column electric terminal 15 of oblique cone metal cap 20 and axial elasticity post 21 common conducting elongate slots 12 inside thus, thereby form another interior electrode contact of automobile cigarette lighter jack.
