The protrusion 121 for offseting with the lower face of stop collar 23 is equipped with, the slot being inserted into for plug bar 22 is provided in protrusion 121
122, the first slide opening 222 that square shape is extended transversely through in bar 22 is plugged, has been slidably connected in the first slide opening 222 in left and right
Symmetrically arranged a pair of limited block 24, one end that limited block 24 is located in the first slide opening 222, which is provided with, to match with the first slide opening 222
The slide unit 241 for the ring-shaped slided is closed, the end of the first slide opening 222 is fixed with to prevent slide unit 241 from the first slide opening 222
The capping 25 of abjection, covers 25 lateral wall and the madial wall of the first slide opening 222 bonds, and the limiting bar portion 242 of limited block 24 is passed through
It is stretched out in outside capping 25 after wearing capping 25, the middle part of housing 11 is provided with the channel 111 passed through for plug bar 22, channel 111
Madial wall on be provided with for limiting bar portion 242 slide up and down and can with limiting bar portion 242 cooperation clamping annular groove
112, the first spring 26 for pushing tow limited block 24, gag lever post are embedded in the first slide opening 222 between a pair of of limited block 24
Guiding surface 243 is provided on the lower face in portion 242, is provided on the upper surface of stop collar 23 in 23 pushing tow limited block of stop collar
It can coordinate when 24 with guiding surface 243 and be oriented to facilitate the pushing tow inclined-plane 231 being pressed into limited block 24 in first slide opening 222,
The second slide opening 223 has been extended transversely through in the plug bar 22 of first slide opening, 222 top, a pair of of steel ball is provided in the second slide opening 223
27, the push plate 28 for being useful for pushing steel ball 27, two push plates are slidably connected in the second slide opening 223 of 27 inside of each steel ball
The second spring 29 for pushing tow push plate 28 is provided in the second slide opening 223 between 28, the end of the second slide opening 223 is fixed with
For steel ball 27 to be prevented to be detached from the sealing plate 20 of plug bar 22, the bellmouth being pierced by for 27 part of steel ball is provided in sealing plate 20
201, the first annular card slot 232 that can coordinate clamping with steel ball 27, first annular card slot are provided on the madial wall of stop collar 23
232 vertical section is arc shape structure, i.e., the vertical section of first annular card slot is arcwall face, on the lateral wall of 22 upper end of plug bar
Several are threaded in circumferentially distributed push-and-pull 224, pushes and pulls the outer cover the plug bar 22 between 224 and shell 21
Equipped with third spring 225;After by using this structure, jack body and header body can lock, so, when
Header body by moment larger external force when being acted on, the appearance for the phenomenon that header body can be avoided to be detached from jack body,
So as to avoid the accident power-off of electrical equipment.
The upper end of stop collar 23 is less than the lowest part of the first slide opening 222 after stop collar 23 offsets with annular nib 221;In this way
After setting, when limited block and annular groove are clamped, stop collar can be avoided to generate interference to limited block.
The groove 211 being caught in for 23 part of stop collar is provided on the lower face of shell 21.
A pair is equipped in jack body to be respectively cooperating with grafting with a pair of conductive piece 212 in header body to realize electricity
The conductive seat 13 of connection, is provided with the through-hole 113 passed through for conductive sheet 212 on housing 11, the top of through-hole 113 be provided with to
Outer expansion first recess 114, first recess 114 in the waterproof rubber sleeve 14 passed through for conductive sheet 212, waterproof rubber are installed
The upper end of gum cover 14 is stretched out in outside the first recess 114, is provided on the lower face of shell 21 for the upper end of waterproof rubber sleeve 14
The second recess 213 stretched into;After by using this structure, after header body is plugged on jack body, work as header body
When accidentally falling wet by water with jack body, since waterproof rubber sleeve is stretched out in outside the first recess, so, water can be avoided
It is flowed into jack body by the gap between conductive sheet and through-hole, so as to effectively avoid the generation of electric shock accidents.
The top of waterproof rubber sleeve 14 is provided with the enlarged portion 141 that conductive sheet 212 is facilitated to be inserted into waterproof rubber sleeve 14;
After by using this structure, conductive sheet can coordinate with enlarged portion is oriented to that conductive sheet is facilitated to pass through waterproof rubber sleeve.
If it is provided with the second annular slot 115 that arterial highway is from top to bottom distributed, waterproof rubber on the madial wall of the first recess 114
The annular convex rib 142 of clamping can be coordinated with the second annular slot 115 by being provided on the lateral wall of gum cover 14;By using this knot
Structure can be brought convenience to the assembling of waterproof rubber sleeve, and in waterproof rubber sleeve aging, can be facilitated to waterproof rubber sleeve
It replaces.
The course of work of the present invention and using process it is:When needing to lock header body and jack body, first will
Plug bar on jack body is inserted into channel, then downward flicking plug bar, and when plugging bar and being pressed, limited block is from outer
Deviate from shell, the first spring pushes out limited block, in bar folding process is plugged, limiting bar portion on limited block eventually with
The top clamping of annular groove;When needing to remove header body from jack body, plug bar is firmly pressed, plugs bar
Lower end can offset with the interior bottom of slot, and stop collar can offset with the upper surface of protrusion at this time, so, be moved down in plug bar
During, stop collar can be because of raised role without moving down, when offseting at the top of limiting bar portion and stop collar, gag lever post
Guiding surface on lower surface can coordinate with the pushing tow inclined-plane at the top of stop collar to be oriented to, and so, limited block can be by
It is pressed into the first slide opening, the steel ball plugged on bar can be snapped onto in first annular card slot, then pinned plug bar and do not put, will
Header body is pulled up from jack body, and plug bar is extracted from jack body, then release plug bar, and plug bar is in third bullet
It is moved up under the action of spring, upper surface and the shell of stop collar offset, and steel ball and limited block are then pressed into shell, and
Under the effect of one spring, the limiting bar portion on limited block offsets with shell, and under the action of second spring, steel ball offsets with shell;
By the setting of waterproof rubber sleeve, water can be avoided to be flowed into jack body by the gap between conductive sheet and through-hole, from
And it can effectively avoid the generation of electric shock accidents.
It should be noted that in the embodiment above, as long as reconcilable technical solution can carry out permutation and combination, this
Field technology personnel can be possible to according to the mathematical knowledge limit of permutation and combination, and therefore, the present invention is no longer to permutation and combination
Technical solution afterwards is illustrated one by one, but it is understood that presently disclosed for the technical solution after permutation and combination.
