Described housing 10 is used to form the connecting pin 2 that prevents splicing ear 11 that electric current passes through and plug 1 when making space that lifter plate 20 described later moves up and down and is exposed to outside electric shock accidents occurs, described housing 10 is formed by the common synthetic resin material with electric insulating quality, and open above, side, in conjunction with lifter plate 20, and makes plug 1 be close to lifter plate 20 and combination therein thus.
And, the inside bottom surface of described housing 10 is fixed with and the connecting pin 2 of plug 1 is inserted and the more than one splicing ear 11 of combination for connecting power supply when, by the physical contact of splicing ear 11 and connecting pin 2, make electric current flow to connecting pin 2 sides by splicing ear 11 thus.
Described lifter plate 20 is for sealing the opening portion above of above-mentioned housing 10 when, make the connecting pin 2 of plug 1 contact or separate with the splicing ear 11 that is fixed on housing 10 inside by moving up and down, described lifter plate 20 is formed by the sheet material with electric insulating quality, and be formed with the more than one patchhole 21 of upper and lower perforation, so that the connecting pin 2 of plug 1 is inserted into housing 10 inner sides by patchhole 21, and described lifter plate 20 can move up and down along the medial surface of described housing 10.
Described descending operation portion 30 is for realizing following action, be inserted under the state of above-mentioned patchhole 21 at the connecting pin 2 of plug 1, by the action of repeatedly pressing plug 1 towards housing 10 inner sides, make connecting pin 2 contact or isolate with splicing ear 11, described descending operation portion 30 comprises: central shaft 22, and below described lifter plate 20, central portion is outstanding vertically downward; Lifting guiding piece 31, is incorporated into the inner side of described housing, can accommodate up or down the lower end of described central shaft; The first elastomeric element 32, is inserted in the inner side of described lifting guiding piece 31, towards central shaft 22 described in the lateral direction resiliency supported of lifting guiding piece 31; Clamping projection 311 is outstanding towards the interior side direction of described lifting guiding piece 31; Pressurization projection 312, outstanding towards the opposite direction of described clamping projection 311, contact with the connecting pin 2 of socket 1; And clamping slot part 23, make described clamping projection 311 according to the decline repeatedly of described central shaft 22 and with decline state clamping or remove clamping.
The outstanding formation of described central shaft 22 central portion below described lifter plate 20, with guiding the moving up and down of lifter plate 20 time, lifter plate 20 is supported, described lifting guiding piece 31 is recessed to form in described housing 10 inner side central portions, and can move up and down the lower end of accommodating described central shaft 22, thus in the time that lifter plate 20 moves up and down, the bottom of central shaft 22 moves up and down along the medial surface of described lifting guiding piece 31, and prevents that the position of lifter plate 20 from departing from.
Described the first elastomeric element 32 makes described lifter plate 20 be subject to the resiliency supported of housing 10 lateral direction, formed by common coil spring etc., and be inserted into the inside of above-mentioned lifting guiding piece 31, below the inside bottom surface and central shaft 22 of two ends difference supporting elevation guiding piece 31, make thus lifter plate 20 move to rapidly the lateral direction of housing 10 according to elasticity.
Decline and make under state that the connecting pin 2 of plug 1 contacts with the splicing ear 11 that is fixed on housing 10 at described lifter plate 20, described clamping projection 311 makes lifter plate 20 be fixed on declined position.Described clamping projection 311 is side-prominent and arrange towards described central shaft 22 in the upper end of above-mentioned lifting guiding piece 31, and can be towards central shaft 22 side resilient movement, and by with the combination of clamping slot part 23 described later, make lifter plate 20 connect and fix or remove clamping under the state declining.
The outstanding formation in described pressurization projection 312 opposition sides towards described clamping projection 311, and there is following effect.That is, after the connecting pin 2 of above-mentioned plug 1 is inserted into the inside of patchhole 21, in the time that lifter plate 20 declines described in pressurization projection 312 contact with connecting pin 2 so that described clamping projection 311 is towards central shaft 22 side shiftings.
Described clamping slot part 23 is given prominence to and caves in and form at the lateral surface of described central shaft 22, along with the decline of central shaft 22, clamping projection 311 connects and fixes with clamping slot part 23, in the time that central shaft 22 declines again, clamping slot part 23 is disengaged with the clamping of clamping projection 311, and lifter plate 20 moves to the upside of housing 10 according to the elasticity of above-mentioned the first elastomeric element 32.
Now, as shown in Figure 8, preferably, described clamping slot part 23 comprises at the lateral surface of above-mentioned central shaft 22: lead-ingroove 231, in the time that lifter plate 20 declines, guides described clamping projection 311 to be inserted into clamping slot part 23 sides; The first top clamping platform 232, take central shaft 22 as benchmark, limits the ascending amount of described clamping projection 311; Bottom clamping platform 233, when pressing the power of socket 1 while removing, connects and fixes clamping projection 311 when making lifter plate 20 increase according to the elasticity of the first elastomeric element 32; The second top clamping platform 234, connects and fixes under the state of bottom clamping platform 233 in described clamping projection 311, while pressing plug 1, limits the climb of described clamping projection 311; And lead-out groove 235, when pressing the power of plug 1 while removing, guiding clamping projection 311 departs from from clamping slot part 23 according to the elasticity of the first elastomeric element 32.
Accordingly, as shown in Fig. 3 to Fig. 7 and Fig. 9 to Figure 13, when plug 1 is incorporated into socket, first after the connecting pin of plug 12 being inserted into the patchhole 21 of lifter plate 20, while pressing plug 1 towards lifter plate 20 sides again, lifter plate 20 will decline, meanwhile, the lower end of central shaft 22 is being inserted under the state of lifting guiding piece 31 inside, breaks away downwards.
Then, if the connecting pin 2 of socket 1 contacts with pressurization projection 312, be close to central shaft 22 towards the outstanding clamping projection 311 in opposition side of pressurization projection 312, and due to lasting decline, clamping projection 311 is inserted and enters the inner side of clamping slot part 23 along the lead-ingroove 231 that is formed at central shaft 22 lateral surfaces, final clamping projection 311 and the first top clamping platform 232 join, and when the further decline of lifter plate 20 is stopped, realize contacting of connecting pin 2 and splicing ear 11.
Under this state, in the time that user removes the power of pressing plug 1, central shaft 22 is pushed to upside according to the elasticity of the first elastomeric element 32, now, clamping projection 311 connects and fixes in bottom clamping platform 233, restriction lifter plate 20 further rises, thereby the connecting pin of plug 12 is maintained with the contact condition of the splicing ear 11 that is fixed on housing 10 inside, is thus connected power supply.
In the time of breakaway plug 1 and socket, under the state of being combined with socket at plug 1, while again pressing plug 1 towards the interior side direction of housing 10, when lifter plate 20 declines, above-mentioned clamping projection 311 rises take central shaft 22 as benchmark, now, clamping projection 311 connects and fixes in the second top clamping platform 234, thereby the further decline of lifter plate 20 is stopped.
And, as mentioned above, be supported in clamping projection 311 under the state of the second top clamping platform 234, when user removes the power of pressing plug 1, clamping projection 311 departs from from clamping slot part 23 completely along lead-out groove 235, and lifter plate 20 rises according to the elasticity of the first elastomeric element 32 afterwards, and connecting pin 2 is separated completely with splicing ear 11, remove thus power supply and connect, thereby only just can realize the combination of plug 1 and socket and separate by repeatedly press the action of plug 1 towards socket side.
And, preferably, make above-mentioned clamping projection 311 only press protruding 312 o'clock of pressurization at connecting pin 2, can be inserted into the inner side of the clamping slot part 23 of depression on central shaft 22, and do not press protruding 312 o'clock of pressurization at connecting pin 2, make clamping projection 311 avoid connecting and fixing in clamping slot part 23, thereby do not inserting under the state of plug 1, when only lifter plate 20 is pressed into the state of housing 10 inner sides, make lifter plate 20 again be pushed to the lateral direction of housing 10 according to the elasticity of the first elastomeric element 32.
Accordingly, can prevent from pushing lifter plate 20 according to other external force except normally, plug 1 time, lifter plate 20 declines and is fixed, thereby makes the safer use of socket become possibility.Moreover, force to pull plug 1 and breakaway plug 1 to the lateral direction of socket in the case of user, lifter plate 20 also can promptly reset into original position, and because connecting pin 2 does not normally contact with splicing ear 11, therefore can prevent flashing between connecting pin 2 and splicing ear 11 from source.
Simultaneously, below above-mentioned lifter plate 20, central authorities are equipped with the swivel plate 40 that is rotatably incorporated into lifter plate 20, this swivel plate 40 is mobile and rotation along with moving up and down of lifter plate 20, open and close thus the patchhole 21 of lifter plate 20, and the inner side of above-mentioned housing 10 is equipped with swivel plate operating portion 50, this swivel plate operating portion 50 is in the time that plug 1 insertion causes lifter plate 20 to decline, described swivel plate 40 is rotated, to open patchhole 21, and when for breakaway plug 1, lifter plate 20 rises, sealing patchhole 21.
Described swivel plate 40 is formed as having the tabular of the length corresponding with the diameter of above-mentioned lifter plate 20, and width is greater than the diameter of above-mentioned patchhole 21, and on central portion, form rotating shaft, to be rotatably incorporated into below lifter plate 20, make thus swivel plate 40 open or sealing patchhole 21 along with the side rotation towards lifter plate 20, this not only can prevent from, because inserting by patchhole 21 electric shock accidents that the conductors such as chopsticks cause, can also preventing the electric leakage and the short circuit accident that cause because entering dust.
Described swivel plate operating portion 50 according to described lifter plate 20 move up and down rotate described swivel plate 40 to open and close patchhole 21, and described swivel plate operating portion 50 comprises: the outstanding guide hump 41 at the both ends of above-mentioned swivel plate 40; Be recessed to form in the medial surface of described housing 10, along first guiding groove 12 that direction caves in vertical direction that moves up and down of described lifter plate 20; Extend to form in the downside of described the first guiding groove 12, and to lopsidedness the second guiding groove 13 of caving in; And be incorporated into the downside of described swivel plate 40, towards the second elastomeric element 51 of housing 10 upside resiliency supported swivel plates 40.
Accordingly, in the time of assembling socket, if seal the position of patchhole 21 at swivel plate 40, guide hump 41 Intercalations are arrived to described the first guiding groove 12, when declining along with lifter plate 20, guide hump 41 declines along the first guiding groove 12, because swivel plate 40 can not rotate, therefore decline with the state that maintains sealing patchhole 21.
Afterwards, along with lifter plate 20 further declines, when guide hump 41 moves along the second guiding groove 13, guide hump 41 has a down dip and tiltedly moves to side direction take housing 10 as benchmark, accordingly, open patchhole 21 when swivel plate 40 rotates, thus the connecting pin 2 of plug 1 can be incorporated into by swivel plate 40 splicing ear 11 of housing 10 inside.
Simultaneously, while making lifter plate 20 increase when separating with socket along with plug 1, the guide hump 41 of swivel plate 40 moves and seals patchhole 21 along the second guiding groove 13 again, now according to the second elastomeric element 51 being formed by common coil spring etc., swivel plate 40 flexibly rises, and realizes rotation more smoothly.
Afterwards, if guide hump 41 is inserted into the first guiding groove 12 sides, patchhole 21 is rotated plate 40 and fully seals, and again prevents that various foreign matters from entering by patchhole 21.
Simultaneously, just be formed with down in the both sides of above-mentioned lifter plate 20 be close to housing 10 medial surfaces and move up and down move up and down guiding piece 24, the described medial surface that moves up and down guiding piece 24 is formed with the opening groove 241 open towards side, in order to guide hump 41 is passed through in the time that above-mentioned guide hump 41 rotates to side.
Accordingly, under the state that does not have to decline at lifter plate 20, if the foreign matter such as chopsticks or nail is inserted into patchhole 21 and presses swivel plate 40, guide hump 41 moves up and down guiding piece 24 described in being stuck in the time that side rotates after the first guiding groove 12 declines, therefore side rotation will be restricted, thereby can prevent that patchhole 21 is open.
And, if the connecting pin 2 of plug 1 is inserted into patchhole 21 and plug 1 while pressing whole lifter plate 20, moving up and down guiding piece 24 will decline together, open the second guiding groove 13 of opening groove 241 thus, thereby make guide hump 41 become possibility by the second guiding groove 13 to side rotation, thereby can more effectively prevent the electric shock accidents that children's naughtiness causes.
Simultaneously, preferably, on above-mentioned swivel plate 40, form angled protrusions 42, the direction of rotation that faces described swivel plate 40 in this angled protrusions 42 is outstanding obliquely, thus in the time that guide hump 41 moves along above-mentioned the second guiding groove 13, the connecting pin 2 of plug 1 is pushed swivel plate 40 to side, spinning movement is realized more swimmingly, moreover also can prevent from being applied to due to excessive pressure the breakage of the swivel plate 40 that swivel plate 40 causes.
Now, preferred version be above-mentioned angled protrusions 42 be formed as having the diameter corresponding with the diameter of described patchhole 21 and outstanding be formed at swivel plate 40 both sides above, but it is also harmless on the both sides of the swivel plate 40 take pivot as benchmark, to form on the whole inclined plane.
