Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and without
It is of the invention in limiting.
Refering to Fig. 1~Fig. 3, plug of the invention includes that 1, two electric current pins 2 of housing, 3, ground connection of spacing collar are inserted
Pin 4 and cover plate 5, the upper surface of wherein housing 1 offer the first groove 11, and the first groove 11 is in length direction through housing 1
One side wall；Two electric current pins 2 are vertical at the upper surface of housing 1 and are respectively arranged on the both sides of the first groove 11；Spacing collar 3 sets
In in the first groove 11, including both sides shell fragment 31；Grounding pin 4 includes pin body 41 and the cunning perpendicular to pin body 41
Dynamic portion 42, with reference to Fig. 4, Fig. 5 and Fig. 8, the both sides of sliding part 42 are all provided with the stopper slot of spaced first stopper slot 421 and second
422, sliding part 42 is inserted in spacing collar 3 and interior slidably in spacing collar 3, and the free end 31a of shell fragment 31 is alternative
Be connected in the first stopper slot 421 or the second stopper slot 422；Cover plate 5 is covered on the upper surface of the first groove 11.
With reference to Fig. 6 and Fig. 7, the bottom surface of the first groove 11 is convexly equipped with limited post 12, and correspondingly, the bottom surface of spacing collar 3 opens up
There is first through hole 32, the bottom surface of sliding part 42 offers elongated slot 423, and limited post 12 is arranged in first through hole 32 and elongated slot 423 successively
Interior, spacing collar 3 is fixed on limited post 12 ad-hoc location of the first groove 11, can prevent spacing collar 3 from deviating from.Limited post 12
Also protrude into the elongated slot 423 of the bottom surface of sliding part 42, during sliding part 42 is slided in spacing collar 3, limited post 12 is also
Can limit slippage portion 42 limit sliding position, prevent sliding part 42 deviate from spacing collar 3.
In addition, in order to realize reliable location of the spacing collar 3 in the first groove 11, being provided with the front end of spacing collar 3
At least one first folding portions 33, correspondingly, housing 1 is provided with the draw-in groove 13 snapped in for the first folding portion 33.Further, limit
The tail end of position sleeve 3 is provided with least one second folding portions 34, and the bottom surface of the first groove 11 is extended with and is snapped in for the second folding portion 34
Connectivity slot 14.
The rectangular in cross-section of the spacing collar 3 of the present embodiment, the section of sliding part 42 is also rectangular, and conveniently the two is slided relatively
It is dynamic.
In order that the sliding action of shell fragment 31 is more smooth, the both sides of sliding part 42 also include slot to make way 420, the first stopper slot
421 and second stopper slot 422 be located at the bottom of slot to make way 420.The free end 31a of the shell fragment 31 of the present embodiment is secured relative to end
(figure do not mark) is closer to the afterbody (i.e. away from the side of pin body 41) of spacing collar 3.
Further, the first stopper slot 421 and the second stopper slot 422 are " V " shape, and free end 31a is " V " shape, in push-and-pull
During, the free end 31a of shell fragment 31 can be slided in slot to make way 420, and in the first stopper slot 421 and the second stopper slot 422
It is interior to switch the locking for realizing different conditions.
More specifically, on cover plate 5 near grounding pin 4 pin body 41 side offer with outside pin body 41
First breach 5a of shape adaptation, offers and pin body in spacing collar 3 near the side of the pin body 41 of grounding pin 4
Second breach 3a of 41 external shape fits, pin body 41 is embedded in when being in contraction state for grounding pin 4.
Such as Fig. 9, when plug need not be powered, grounding pin 4 is in collapsed state, and the free end 31a of shell fragment 31 is located at
The locking of the collapsed state of pin 4 is grounded in second stopper slot 422, the overall dimensions of plug reduce, be easy to preferably to carry,
Packaging storage and transport；Such as Figure 10, when plug needs energization to use, shell fragment 31 and spacing collar 3 are overcome under external force
Elastic conflict power, you can pull out grounding pin 4, when shell fragment 31 free end 31a be located at the first stopper slot 421 in when, you can
It is grounded the locking that pin 4 stretches out state.
When the plug is assembled, comprise the following steps：
S01, the sliding part 42 of grounding pin 4 is inserted into spacing collar 3；
S02, spacing collar 3 is fixed in the first groove 11 of housing 1；
S03, the upper surface that cover plate 5 is fixed on the first groove 11.
Wherein, to make assembling process one-time-reach-place, also needed to the limited post 12 of the bottom surface of the first groove 11 before step S02
The first through hole 32 of the bottom surface of spacing collar 3 and the elongated slot 423 of the bottom surface of sliding part 42 are directed at simultaneously.Cover plate 5 passes through threaded fastener
The upper surface of the first groove 11 is fixed on, and its upper surface is concordant with housing 1.
Preferably, step S02 also includes for the first folding portion 33 and the second folding portion 34 on spacing collar 3 inserting housing
1 corresponding site.
It is understood that the plug of the embodiment of the present invention can be the plug of common connection electric wire, or each
Plant the plug of charger.
The grounding pin of plug of the invention is flexibly connected with housing, and grounding pin can slidably reciprocate in the housing, and lead to
The shell fragment crossed in spacing collar carries out spacing with the sliding part cooperation of grounding pin；When plug is used, need to only pull out ground connection and insert
Pin, the sliding part of grounding pin carries out limitation locking by the shell fragment in spacing collar；When plug is not used, ground connection need to only be inserted
In pin push-in housing, the sliding part of grounding pin carries out limitation locking again by the shell fragment in spacing collar, and grounding pin is to receive
It is contained in housing, the volume of plug diminishes, transport and packing cost can be reduced, is easy to carry.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art
For member, on the premise of the application principle is not departed from, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as the protection domain of the application.
