Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Consult Fig. 1 ~ Fig. 3, plug of the present invention comprises housing 1, two electric current pins 2, spacing collar 3, grounding pin 4 and cover plate 5, and the upper surface of its middle shell 1 offers the first groove 11, first groove 11 runs through housing 1 sidewall at length direction; Two electric current pins 2 are vertical at housing 1 upper surface and are located at the first groove 11 both sides respectively; Spacing collar 3 is located in the first groove 11, comprises the shell fragment 31 of both sides; Grounding pin 4 comprises pin body 41 and the sliding part 42 perpendicular to pin body 41, composition graphs 4, Fig. 5 and Fig. 8, the both sides of sliding part 42 are equipped with first stopper slot 421 and second stopper slot 422 at interval, sliding part 42 is inserted in spacing collar 3 and, the free end 31a of shell fragment 31 is optionally connected in the first stopper slot 421 or the second stopper slot 422 in spacing collar 3 slidably; Cover plate 5 is covered on the upper surface of the first groove 11.
Composition graphs 6 and Fig. 7, the bottom surface of the first groove 11 is convexly equipped with limited post 12, correspondingly, spacing collar 3 bottom surface offers the first through hole 32, sliding part 42 bottom surface offers elongated slot 423, limited post 12 is arranged in the first through hole 32 and elongated slot 423 successively, and spacing collar 3 is fixed on the ad-hoc location of the first groove 11 by limited post 12, can prevent spacing collar 3 from deviating from.Limited post 12 also stretches in the elongated slot 423 of sliding part 42 bottom surface, and when in the process that sliding part 42 slides in spacing collar 3, limited post 12 also can the limit sliding position in limit slippage portion 42, prevents sliding part 42 from deviating from spacing collar 3.
In addition, in order to realize the reliable location of spacing collar 3 in the first groove 11, be provided with at least one first folding portion 33 in the front end of spacing collar 3, correspondingly, housing 1 is provided with the draw-in groove 13 snapped in for the first folding portion 33.Further, the tail end of spacing collar 3 is provided with at least one second folding portion 34, first groove 11 bottom surface and is extended with the connectivity slot 14 snapped in for the first folding portion 33.
The rectangular in cross-section of the spacing collar 3 of the present embodiment, the cross section of sliding part 42 is also rectangular, relative sliding both convenient.
In order to make the sliding action of shell fragment 31 more smooth and easy, the both sides of sliding part 42 also comprise slot to make way 420, and the first stopper slot 421 and the second stopper slot 422 are located at bottom slot to make way 420.The free end 31a of the shell fragment 31 of the present embodiment is relative to the afterbody (namely away from the side of pin body 41) of its stiff end (figure does not mark) closer to spacing collar 3.
Further, first stopper slot 421 and the second stopper slot 422 are " V " shape, and free end 31a is " V " shape, in push-and-pull process, the free end 31a of shell fragment 31 can slide in slot to make way 420, and in the first stopper slot 421 and the second stopper slot 422, switch the locking realizing different conditions.
More specifically, the side of the pin body 41 near grounding pin 4 on cover plate 5 offers the first breach 5a with pin body 41 external shape fits, offer the second breach 3a with pin body 41 external shape fits at spacing collar 3 near the side of the pin body 41 of grounding pin 4, when being in contraction state for grounding pin 4, pin body 41 embeds.
As Fig. 9, when plug does not need energising, grounding pin 4 is in collapsed state, and the free end 31a of shell fragment 31 is positioned at the locking that the second stopper slot 422 is grounded pin 4 collapsed state, the overall dimensions of plug reduces, and is convenient to carry better, pack storage and transport; As Figure 10, when plug needs energising to use, overcome shell fragment 31 and the elasticity conflict power of spacing collar 3 under external force, grounding pin 4 can be pulled out, when the free end 31a of shell fragment 31 is positioned at the first stopper slot 421, the locking that pin 4 stretches out state can be grounded.
When this plug is assembled, comprise the steps:
S01, the sliding part 42 of grounding pin 4 is inserted spacing collar 3;
S02, spacing collar 3 is fixed in the first groove 11 of housing 1;
S03, cover plate 5 is fixed on the upper surface of the first groove 11.
Wherein, for making assembling process one-time-reach-place, before step S02, also need the limited post 12 of the first groove 11 bottom surface to aim at the first through hole 32 of spacing collar 3 bottom surface and the elongated slot 423 of sliding part 42 bottom surface simultaneously.Cover plate 5 is fixed on the upper surface of the first groove 11 by threaded fastener, and its upper surface is concordant with housing 1.
Preferably, step S02 also comprises the corresponding site the first folding portion 33 on sliding part 42 and the second folding portion 34 being inserted housing 1.
Be understandable that, the plug of the embodiment of the present invention can be the plug of common connection electric wire, also can be the plug of various charger.
The grounding pin of plug of the present invention is flexibly connected with housing, and grounding pin can slidably reciprocate in the housing, and by the shell fragment in spacing collar to coordinate with the sliding part of grounding pin carry out spacing; When plug uses, only need pull out grounding pin, the sliding part of grounding pin carries out limitation locking by the shell fragment in spacing collar; When plug does not use, only need push in housing by grounding pin, the sliding part of grounding pin carries out limitation locking again by the shell fragment in spacing collar, namely grounding pin is accommodated in housing, the smaller volume of plug, can reduce transport and packing cost, be easy to carry.
The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection range of the application.
