Embodiment
See also Fig. 1 to Figure 15, charging plug of the present invention comprises header body 1, two buttons 8, over cap 2, two mount pads 3 and two connectors 4.This header body 1 is made up of head 11 that is positioned at front end and the stage portion 12 that is positioned at the rear end, this head 11 is square, it has the upper and lower, left and right that are used for cooperating with the charging socket grafting and cooperates wall 111,112,113,114 and be connected the front end face 115 that these upper and lower, left and right cooperate wall, this upper and lower cooperation wall 111,112 is a horizontal plane, and this left and right cooperation wall 113,114 is a vertical plane.This front end face 115 is provided with opening 116, certainly this opening 116 along this header body axially to be recessed into be formed with the charging chamber 13, be installed with plain conductor post 14 in this charging chamber 13.This stage portion 12 is provided with two guide holes 121 that axially run through, and this stage portion 12 exceeds the upward cooperation wall 111 of head 11.
The left and right cooperation wall 113,114 of this header body all is concaved with strip mounting groove 117, and the diapire of this mounting groove 117 has two installing holes 119 that location hole 118 reaches about this location hole symmetry certainly, and each mounting groove 117 is all placed a button 8.The middle part of each button 8 is installed in the location hole 118 by securing member (as screw) 9, each button 8 is equipped with shrinkage pool 81 towards the position of corresponding two installing holes 119 of a side of mounting groove 117, all be placed with a compression spring in each shrinkage pool 81, one end of this compression spring (not shown) is packed in the shrinkage pool 81 of button, its other end is packed in the installing hole 119 of header body 1, thereby makes each button 8 resiliency supported on this header body 1.
This over cap 2 is square tabular, and its upper edge is provided with three projections 21 that are separated, and forms two breach 22 between these three projections 21, and each projection 21 equal levels are penetrated with shaft hole 23, and each projection 21 all exceeds the upward cooperation wall 111 of head 11.First, second mounting panel 32,33 that each mount pad 3 includes a base plate 31 and bends vertically upward from these base plate 31 opposite ends, these first mounting panel, 32 levels are penetrated with shaft hole 34.Each connector 4 is shaft-like and along the axial placement of header body.
During installation, first mounting panel 32 of two mount pads 3 is inserted respectively in the corresponding breach 22 of over cap 2, the shaft hole 34,23 of first mounting panel 32 and over cap 2 is aligned, then aim at this shaft hole 34,23 and penetrate the rotating shaft 17 of a level, then with an end cap upper end cover of this rotating shaft 17, its other end snaps in the draw-in groove spacing with the rubber snap ring, to prevent extraction in these rotating shaft 17 rotation axis holes 34,23; Second mounting panel 33 of two mount pads 3 is affixed with corresponding connector 4 respectively, the other end of each connector 4 all passes the guide hole 121 of stage portion 12, and the part that this connector 4 and guide hole 121 matched in clearance and each connector 4 pass guide hole 121 all is installed with and is connected plug screw 6; Also be arranged with rubber spring 5 on each connector 4, the two ends of this rubber spring 5 compress respectively after stage portion 12 and second mounting panel 33. install, and this over cap 2 is in vertical position, and it is close to the front end face 115 of header body and seals the opening 116 of header body; The base plate 31 of each mount pad attaches going up of this header body and cooperates wall 111, thereby each mount pad can slide along the axial front and back of header body along cooperation wall 111 on this.
This charging socket comprises jack body 10 and plain conductor post 16, this jack body 10 roughly is square, its front end face 100 is provided with opening 101, certainly this opening 101 along this jack body axially form mating cavity 102 to being recessed into, the size of this mating cavity 102 and the head of charging plug 11 are complementary.This mating cavity 102 has chamber, upper and lower, left and right wall 103,104,105,106, axially recessed epicoele wall 103 from this opening 101 along jack body forms two first avoiding hollow grooves 107, these two first avoiding hollow grooves 107 are blind groove and all connect with mating cavity 102, and these two first avoiding hollow grooves 107 are corresponding one by one with two mount pads 3 of charging plug.Form two second avoiding hollow grooves 108 from this opening 101 along axially being recessed into left and right chamber wall 105,106 respectively of jack body, these two second avoiding hollow grooves 108 be blind groove and all with mating cavity 102 perforations, and these two second avoiding hollow grooves 108 two buttons 8 with charging plug are corresponding respectively.In addition, this left and right chamber wall is the hole clipping 109 that runs through of the level of being equipped with also, and this hole clipping 109 all is communicated with corresponding second avoiding hollow groove 108.
When needs charge to electric motor car; at first open the sealing enclosing cover of charging socket; the button 8 of holding the charging plug middle part also firmly inserts the mating cavity 102 of charging socket; because the projection 21 of over cap is higher; so this projection 21 at first hits the front end face 100 of charging socket; under the stopping of front end face 100; force over cap 2 17 to rotate around the shaft; along with the continuity of insert action, the internal face 1031 of the epicoele wall 103 of charging socket makes over cap 2 be forced to revolve to turn 90 degrees (be over cap 2 be turned to horizontal level and attach going up of header body and cooperate wall 111).Because the height of first avoiding hollow groove 107 and width are respectively greater than the height and the width of the mount pad 3 of correspondence, therefore a bit of insertion stroke of following is laborsaving relatively, when the diapire 1071 of first avoiding hollow groove 107 hits second mounting panel 33 of mount pad, begin to compress spring 5, and can push away over cap 2, mount pad 3, connector 4 and connect plug screw 6 and move after together; On the other hand under the effect of grip, make its interior compression spring of button 8 extruding, the part that forces button 8 to stretch out left and right cooperation wall 113,114 becomes seldom, make the internal face 1051,1061 of this button 8 and the left and right chamber of charging socket wall 105,106 almost not have frictional force, when the fixture block 82 of button 8 reaches hole clipping 109 places of charging socket, stop pressing keys 8, fixture block 82 is stuck in the hole clipping 109, just can charge for a long time.Because screw 9 sinks in the screw hole 83 of button, so screw 9 can not interfered with second avoiding hollow groove 108.
After charging electricity, pressing keys 8 can be deviate from fixture block 82 in hole clipping 109 again, and firmly outer drawing, and charging plug is extracted from charging socket fully.The spring 5 of this moment in plug return gradually, and promote mount pad 3 and also return to original position.When mount pad 3 returned to original position, over cap 2 was rotated down 90 degree under the effect of gravity, make the front end face 115 of its adhesive strip applying charging plug and seal opening 116, returns to initial condition, finishes a samsara.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
