Embodiment

To describe various execution mode of the present utility model in detail by means of only exemplary approach now.

Fig. 1 shows the sectional view of the socket according to execution mode of the present utility model.In this embodiment, exemplarily socket of the present utility model is described with wall socket.As shown in Figure 1, this socket comprises the pedestal be integrally formed by base 1 and cover plate 2.Base 1 is provided with conductive connecting piece 11, cover plate 2 has two jacks 21,21 ' of two latches 10 for a plug.Each conductive connecting piece 11 is corresponding with the position of corresponding jack 21,21 ' respectively, and to make when the latch 10,10 ' of plug inserts from jack 21, each latch of plug can contact with corresponding conductive connecting piece 11 and realize being electrically connected.

Inner at the pedestal of socket, the interior volume of namely surrounding at cover plate 2 and base 1 is respectively two jacks 21,21 ' and arranges two independent shutter movable parts 3 and 4.As Figure 2-3, shutter movable part 3 and 4 can have similar or identical structure.Shutter movable part 3 and 4 has first end and the second end, on first end, wherein have shutter 33,43.The shape of shutter 33,43 mates the shape of jack 21,21 ' substantially, thus is convenient to be positioned in jack 21,21 ' and sentences closed jack, but can and jack 21,21 ' between have suitable gap.The first end of shutter movable part 3 and 4 is also provided with the first shutter guide frame 34,44, and on the second end at shutter movable part 3 and 4, is also provided with the second shutter guide frame 35,45.First shutter guide frame 34; 44 both sides being arranged on the first end of shutter movable part 3 and 4; second shutter guide frame 35; 45 both sides being arranged on the second end of shutter movable part 3 and 4, guide shutter movable part 3 and 4 to move along the track limited for being slidably matched with the pedestal guide frame be arranged on pedestal.

In execution mode as in Figure 2-4; first shutter movable part 3 has substantially identical shape with the second shutter movable part 4; and between its first end and the second end, all there is fluting; and fluting 36 in the difference of the two is in the second shutter movable part 4 fluting 46 to the first shutter movable part 3 is wider, in the fluting 46 making the first shutter movable part 3 can extend in the second shutter movable part 4.But the fluting 36 in the first shutter movable part 3 at least allows the latch 10 of plug to stretch at the width near the second end place.As shown in Figure 4, the first shutter movable part 3 extend in the fluting 46 in the second shutter movable part 4, and is arranged in pedestal with the second shutter movable part 4 symmetrical chiasma.

In the execution mode shown in Fig. 2-4, the first shutter guide frame 34,44 and the second shutter guide frame 35,45 is the direction protrusion extended from shutter movable part 3,4 side, to engage with the gathering sill be arranged on pedestal.Any other guide frame being slidably matched for the first shutter guide frame 34,44 and the second shutter guide frame 35,45 and pedestal guide frame also can be provided.Such as; can by the first shutter guide frame 34; 44 and the second shutter guide frame 35; one or all in 45 is set to gathering sill; and pedestal guide frame is set to gathering sill slip joint and be defined for the first shutter guide frame 34; 44 and second guiding rib of motion path of shutter guide frame 35,45.

Shutter 33,43 closed jack face up horizontal positioned time; first shutter guide frame 34; 44 are positioned at higher than the second shutter guide frame 35; on the horizontal plane of 45; so that guide shutter movable part 3,4 to move to open shutter blocking jack along the track limited, this will be described in detail later.

For the ease of arranging pedestal guide frame in pedestal, as shown in Figure 5, a mounting groove 14 can be offered in the side near cover plate 2 in pedestal.Mounting groove 14 is communicated with the space for arranging conductive connecting piece 11.Pair of angled guide surface 12 and horizontal guide surface 13 is provided with in the bottom of mounting groove 14.One inserted block 5 (see Fig. 6) can be plugged in this mounting groove 14.Guiding surface 51 and step surface 52 is provided with inside inserted block 5.When inserted block 5 is inserted into after in mounting groove 14; angular guide surfaces 12 on mounting groove 14 will coordinate the oriented groove 22 being formed and be used for being slidably matched with the first shutter guide frame 34,44 with the guiding surface 51 on inserted block 5; and the horizontal guide surface 13 on mounting groove 14 will coordinate the horizontal guide slot 23 being formed and be used for being slidably matched with the second shutter guide frame 35,45 with the step surface 52 on inserted block 5, as shown in Figure 7.In this case, jack 21,21 ' will be positioned on inserted block 5.The setting of the inserted block 5 be separated with pedestal is convenient to install inserted block 5 again to form complete gathering sill after shutter movable part 3,4 is easily put into mounting groove 14.Certainly, the inserted block 5 of separation also can not be set, and directly gathering sill be formed in pedestal.

This oriented groove 22 becomes the angle of inclination of on-right angle with the axis of jack; and tilt to extend along the direction of motion of the latch insertion jack of plug towards the central authorities of two jacks; thus when latch inserts in jack, the first shutter guide frame 34,44 of the first end of bolt driving shutter structure slides towards jack depths and towards the central authorities of two jacks.The direction of line of horizontal guide slot 23 with the axial vertical of jack and along the center being parallel to two jacks 21,21 ' extends; thus when the first shutter guide frame 34,44 of the first end of bolt driving shutter structure is along oriented groove 22 linear slide, horizontal guide slot 23 will guide the second shutter guide frame 35,45 of the second end of shutter structure along horizontal guide slot 23 linear slide.Like this; when latch inserts in jack; two the shutter bascules 3,4 being respectively used to two jacks can move towards each other; and because the first shutter guide frame 34,44 and the second shutter guide frame 35,45 to be in different level heights and movement locus is different; shutter movable part 3,4 is also become gradually " lying flat " while moving towards each other, namely certain rotation occurs and makes its first end reduce height gradually.Like this; two shutter movable parts 3,4 can move when not interfering each other simultaneously and make shutter on it 33 and 43 axially to move but also towards the central mobile of two jacks to direction of insertion not only along jack, thus stagger to enable latch continue to be deep into jack inside with jack 21,21 '.

Because the cover plate 2 of pedestal or the outer wall of inserted block 5 have certain thickness, the jack thus it formed has certain degree of depth (such as several millimeters).And if the cover 6 (it equally also will form the cover hole aimed at the jack on pedestal, see Fig. 1) be also provided with on pedestal for decorative effect, then the overall depth in jack and cover hole will be larger.Desirably the shutter 33,43 of shutter movable part 3,4 is extend in jack inside; even make the top of shutter 33,43 (namely towards the face outside jack) concordant with the outermost edges (such as the outer surface of cover 6) in cover hole, to obtain substantially smooth socket outer surface.In this case; when plug is inserted in jack; in order to make shutter 33,43 can exit narrow jack first smoothly, need to make shutter 33,43 in jack substantially only along moving axially of jack substantially not or very by a small margin in the other direction (on the direction especially perpendicular to jack axis) mobile.For this reason, pedestal guide frame can be that the first shutter guide frame 34,44 of the first end of shutter bascule 3,4 provides when plug just inserts in jack only along the guiding of jack axis.Such as, as shown in Figure 7, the upper end more outside jack of oriented groove 22 connects one end substantially along the axially directed groove of jack axis, it is communicated with oriented groove 22.Like this, when plug just inserts in jack, the first shutter guide frame 34,44 of shutter bascule 3,4 first end only can move axially to exit narrow jack smoothly along jack substantially.

Shutter movable part 3,4 first end and be also provided with spring fitting post 37,47 in the inner side of fluting 36,46, and in pedestal, be provided with spring supporting post 12.Between the spring fitting post 37,47 and spring supporting post 12 of each shutter movable part 3,4, back-moving spring 7 is set respectively; jack 21 is exited with the latch when plug; shutter movable part 3 is forced by the restoring force of back-moving spring 7 after 21 '; 4 is oppositely mobile again to close corresponding jack 21,21 ' along the track limited.Advantageously, spring fitting post 37,47 is roughly arranged along the bearing of trend of oriented groove 22, and spring supporting post 12 is also provided with the inclined end face of the bearing of trend being approximately perpendicular to oriented groove 22, back-moving spring 7 is fixed to and substantially extends along the bearing of trend of oriented groove 22.The back-moving spring 7 of such setting is convenient to provide restoring force along the bearing of trend of oriented groove 22 for shutter movable part 3,4, so that the orbiting motion that shutter movable part 3,4 successfully limits along oriented groove 22 is to the position closing jack.

As shown in Figure 8 a-8b; when the latch 10,10 ' of plug not yet inserts the shutter surface in jack or in just pin jack; shutter movable part 3,4 is only subject to the effect of the restoring force of back-moving spring 7 and is guided as making the shutter 33,43 of its first end be near jack 21 by pedestal guide frame; the position in 21 ' outside; such as; to extend in jack and the position roughly flushed with the outer surface of panel 2 or cover 6, with closed jack.Now; the the first shutter guide frame 34,44 being positioned at the first end of shutter movable part 3,4 is in its position along the top of the axis of jack (direction of the latch of plug insertion jack being defined as direction from top to bottom); and the guiding surface 51 on distance inserted block 5 has certain interval; and the second shutter guide frame 35,45 being positioned at the second end of shutter movable part 3,4 is positioned at it near the position in the middle of two jacks 21,21 '.

As shown in Fig. 9 a-9b, at the latch 10 of plug, 10 ' inserts jack 21 a little, time in 21 ', due to shutter 33, 43 are constrained in the narrow jack be formed on panel 2 or cover 6, shutter 33, 43 and shutter movable part 3, the first end of 4 only can by latch 10, 10 ' promotes and overcomes the power of back-moving spring 7 and only move down along the axis of jack, until the first shutter guide frame 34, 44 start to touch the guiding surface 51 on inserted block 5 till, thus shutter 33, 43 have exited narrow jack 21 substantially, 21 ' and enter into the inner space of more spacious pedestal.In motion process, the second shutter guide frame 35,45 substantially keeps motionless or a little away from the central mobile of two jacks.Therefore, the mass motion of shutter 33,43 similarly is more the pivoting action of shutter 33,43 around the second shutter guide frame 35,45, thus shutter 33,43 may occur to tilt relative to the faint pivotable of jack axis in the process exiting jack.Because the space between the first shutter guide frame 34,44 and guiding surface 51 is very little, its degree of depth (several millimeters) only allowing shutter to move to just to exit jack, therefore, the pivotable tilt quantity that shutter produces in the stroke that this is little is very little.Fit clearance between shutter 33,43 and jack 21,21 ' is enough to allow shutter in this jack, produce this little inclination and shutter can not be made to be stuck in jack.

As shown in Figure 10 a-10b; jack 21 is inserted further at the latch 10,10 ' of plug; time in 21 ', the inclined trajectory that starts to limit along guiding surface 51 downwards and to two jack centralized movement, and can not be subject to the constraint of jack by the first shutter guide frame 34,44.Now; because the first end of the first shutter guide frame 34,44 and shutter movable part 3,4 has significant movement travel, the second direction of shutter guide frame 35,45 also by being thus pushed along horizontal guide slot 23 towards the central authorities away from two jacks of the second end of shutter movable part 3,4 is moved.Now; because the first shutter guide frame 34,44 and second shutter guide frame 35,45 is directed along different pedestal guide frames; the movement locus of the two is different; wherein the first shutter guide frame 34,44 has significantly along the component motion of jack axis with along the component motion perpendicular to jack axis; second shutter guide frame 35,45 then has than the first shutter guide frame 34,44 larger component motions perpendicular to jack axis, and almost not along the component motion of jack axis.Due to the different movement locus at the two ends of shutter movable part 3,4; make the actual compound motion having carried out comprising translation and rotation of shutter movable part 3,4; and shutter movable part 3,4 " is lain flat " gradually; also occur towards the component motion of the central authorities of two jacks to make shutter 33,43 thereupon; namely two shutters 33,43 move towards each other, with two jacks 21,21 ' that stagger.

As shown in Figure 11 a-11b, jack 21 is inserted further at the latch 10,10 ' of plug, 21 ' and after shutter 33,43 and two jacks 21,21 ' are staggered completely, two shutters 33,43 will be more close each other, and expose a part for the fluting 46 in second shutter movable part 4 between the shutter 33 of first shutter movable part 3 and the second shutter guide frame 45 at the second end place of second shutter movable part 4; Same, between the shutter 43 of second shutter movable part 4 and the second shutter guide frame 35 at the second end place of first shutter movable part 3, expose a part for the fluting 36 in first shutter movable part 3.Now; the latch 10,10 ' of plug just can be each passed through these two flutings 46,36 and from the shutter movable part 3 corresponding with the jack that each latch inserts; the outside of the first end of 4 is through shutter movable part 3; 4, until latch to be inserted into pedestal completely inner and respectively at conductive connecting piece 11 electrical contact.

The latch of plug is being extracted in the process of jack; back-moving spring 7 will promote shutter movable part 3,4 according to the track identical with movement locus when latch inserts before along the incline direction roughly the same with guiding surface 51; but move along the direction contrary with it, make shutter 33,43 again get back to the position of closed jack 21,21 '.

Shutter movable part 3,4 in socket of the present utility model is owing to having guide frame respectively at first end and the second end; and make this first shutter guide frame and the second shutter guide frame have different movement locus; thus, when shutter movable part 3,4 is moved by bolt driving, translation can be carried out and rotate the compound motion synthesized.Like this; two shutter movable parts 3,4 can either successfully move and non-interference to open jack; shutter movable part 3,4 entirety does not almost move in the axially occupied space of jack simultaneously; because the second shutter guide frame is substantially along the axial motion perpendicular to jack, and the first shutter guide frame along the final position moved to of jack axis also not more than the position of the second shutter guide frame along jack axis.Therefore; non-integral realizes and the staggering of jack along the mode that jack axially moves down in the mode of " lying flat " for two shutter movable parts 3,4; this makes this shutter movable part can not occupy more limited axial space in the pedestal of socket in motion process, thus makes socket can design thinner.In addition, this also makes the motion of shutter movable part 3,4 that the latch of plug can not be hindered to contact with the smooth of conducting connecting part 11 in pedestal.

In order to realize the compound motion of shutter movable part 3,4 above-described " lying flat "; first shutter guide frame 34,44 is not must move along the angled straight lines path limited by guiding surface 51 described in above execution mode; but can according to the directed movement of various track; such as move along arching trajectory or other curvilinear paths; as long as ensure the existing component axially downward along jack of the motion of the first shutter guide frame, have again towards the component perpendicular to jack axis of the central authorities of two jacks.And the second shutter guide frame 35,45 along the route movement of straight line being strictly perpendicular to the axis of jack described in above execution mode, and also neither can have the component motion along jack axis a little.As long as ensure the first shutter guide frame 34; 44 are greater than the second shutter guide frame 35 along the component motion of the axis of jack; 45 along the component motion of the axis of described jack; and the first shutter guide frame 34; 44 are less than the second shutter guide frame 35 along the component motion perpendicular to the axis of jack; 45 along the component motion perpendicular to the axis of jack; just can realize the compound motion of " lying flat " of shutter movable part 3,4, with when hardly along jack axial integral move or less move along jack axial integral realize and the staggering of jack.Based on this principle, coordinate design can be respectively used to the pedestal guide frame of the first shutter guide frame 34,44 and the second shutter guide frame 35,45, meet above requirement to make the movement locus of the two.

As in Figure 2-4, in one embodiment, the second end of each shutter movable part 3,4 is respectively equipped with locking projection 38,48.Locking projection 38,48 is given prominence to towards with shutter 33,43 identical sides.Like this, when two shutter movable parts 3,4 arranged crosswise, the locking projection 38,48 of each shutter movable part 3,4 is just positioned at the below of the shutter 43,33 of the first end of another shutter movable part 4,3.As shown in figure 12; when only there being plug latch 10 to be inserted into a jack 21 in two jacks; there is not any motion owing to not being subject to the effect of latch in the shutter movable part 4 corresponding to the jack do not inserted by latch, thus the locking projection 48 of shutter movable part 4 second end is still positioned at the below of the shutter 33 of shutter movable part 3.Now; when the shutter 33 of shutter movable part 3 moves and the displacement occurred along jack axis after touching the locking projection 48 be positioned at below it under the guiding of guiding surface 51; due to the stop of locking projection 48, shutter 33 can not continue to further move to along guiding surface 51 degree opening jack 21 again.Therefore, single latch 10 cannot continue to be inserted into more depths in jack 21 to contact with conducting connecting part 11 wherein.Thus, the single latch of plug is prevented to be inserted into risky operation in the jack of socket.

But this locking projection 38,48 does not hinder two of plug latches to insert normal running in two jacks simultaneously.As shown in Figure 11 a-11b, when two latches 10 of plug, 10 ' inserts two jacks 21 respectively simultaneously, time in 21 ', two shutter movable parts 3, 4 all by actuation movement, make two shutter movable parts 3, locking projection 38 on second end of 4 and the second end, 48 all move towards the position of the central authorities away from two jacks, thus each shutter movable part 3, locking projection 38 on 4, 48 all leave another shutter movable part 4, shutter 43 on the first end of 3, the below of 33 and no longer stop shutter 43, continuation the moving down on jack axial direction of 33.Like this; shutter 43,33 can continue the oblique movement of guiding along pedestal guide frame; to expose the fluting 46,36 of each shutter movable part 3,4 between shutter 43,33 and locking projection 38,48, contact with conducting connecting part 11 for two latches 10,10 ' are each passed through.

In an alternate embodiments, shutter movable part 3,4 can not be arranged in a crossed manner.But; shutter movable part 3; one in 4 is separated setting with another; namely the first shutter movable part 3 and the second shutter movable part 4 are positioned at the both sides of the central authorities of two jacks 21,21 ' and without any overlap, and the first shutter guide frame 34,44 to the second shutter guide frame 35,45 is closer to the central authorities of two jacks 21,21 ' respectively completely.In this case; in pedestal guide frame to the path of navigation of the first shutter guide frame 34,44 and the second shutter guide frame 35,45 should arranged in a crossed manner with the shutter movable part described before when path of navigation compared with; on the direction of the axis perpendicular to jack oppositely, then identical on the direction along jack axis.Such as, when the angled straight lines path motion limited by guiding surface 51, this guiding surface 51 tilts to extend towards the direction away from the central authorities of two jacks near the level height of jack and the position axially that is in jack to jack depths; In pedestal guide frame, the first shutter guide frame 34,44 than correspondence is then positioned at more away from the position of the central authorities of two jacks to the path of navigation of the second shutter guide frame 35,45.Like this; when the latch of plug stretches into jack 21; time in 21 ', the first end of two shutter movable parts 3,4 is driven away from each other; thus two shutter movable parts 3; 4 equally also can there is translation and rotate " lying flat " motion be compounded to form, thus each latch of plug can in the outside of the first end of the shutter movable part 3,4 corresponding with inserted jack through shutter movable part 3; 4 and the pedestal inserting socket stretch out, to contact with conducting connecting part.In this case, two shutter movable parts 3,4 can not overlap, and also pass for latch and another shutter movable part without the need to arranging fluting 36,46 thereon.

In one embodiment, shutter 33,43 is basic plane towards the side outside jack.Like this when shutter stretches in jack, observe from socket outside, jack is by basic concordant with the cover plate 2 of socket.When the pedestal of socket is also provided with ornamental cover 6 outward, under the state that shutter movable part 3,4 closes jack, the shutter 33,43 of shutter movable part 3,4 substantially concordant with the outer surface of described cover 6 towards the plane outside jack.Like this, observe from the outside of socket, shutter and the cover at jack place almost combine together, and easily cannot observe jack.Thus, more beautiful and clean socket outer surface is obtained.

The shutter being basically parallel to the surface of receptacle cover plate or cover it also avoid fouls such as accumulating dust in jack or on shutter, thus is conducive to the clean and tidy outward appearance obtaining socket further.And, because the shutter in each jack is formed by monolithic shutter part, it also avoid the joint line occurring being formed between multiple parts of shutter in single jack, make socket cleaner and tidier.
