Rolling wheel body 19 is made into different version in these two embodiment.On housing 13, inserting the transitional region that is shaped between body 17 and the rolling wheel body 19.

In housing 13, settle a plurality of fixing and a plurality of movable members (comparison diagram 9-12).Wherein electronic devices and components 21 are used for the alternating current of 230V-power supply network is converted to a kind of low-voltage DC.These electronic devices and components 21 are arranged in the inside and transitional region of inserting body.Electronic devices and components 21 can buy on market under the size situation of describing, and just no longer accurately have described its layout of single member this moment.Single member is moved a little for the former of locus thereby from the position that they occupy known components and parts.Components and parts 21 are connected on the contact plug 15 by two engagement hooks 23 (Figure 10,11 and 12).The formation of this contact is to realize by the position 24 (Figure 10) that touches between an engagement hook 23 and a contact plug 15 respectively.In housing 13, settled a rolling wheel 25 that is used to reel twisted wire cable 27 in addition.Rolling wheel 25 is rotatably supported in the housing 13 around its axis 30.Relatively long twisted wire cable 27 (for example length is 1m) can be wound onto on the rolling wheel 25, and is carrying a low pressure plug 29 on the end of outside.The end of having been reeled within the twisted wire cable 27 then is fixed on the rolling wheel 25.Connection between twisted wire cable 27 and electronic devices and components 21 constitutes by two self-cleaning contacts 31.

Twisted wire cable 27 penetratingly is directed by housing 13, and is wound onto at least in part on the described rolling wheel 25.89 places, position of leaving in twisted wire cable 27 on housing constitute a bearing 32 to be used to keep this low pressure plug 29.

Rolling wheel 25 utilizes a helical spring 33 with respect to housing 13 quilt tensionings in advance.Rolling wheel has a columniform coiling surface 34 (Fig. 7 and 8) and has the sidewall 35,36 of two annulars opposite each other.On the first side wall 35, be provided with helical spring 33, to be used to rotating rolling wheel 25 and the twisted wire cable 27 of reeling with connecting.On the first side wall 35, constitute one around cylindrical shape edge 37.This edge 37 rests on a partition wall 39 (first embodiment 11) slidably and goes up or rest on the housing wall (end part 78 of second embodiment 12), and therefore sets up a clearance space, has wherein settled helical spring 33 and can tensioning and loose.

Rolling wheel 25 is supported on the pivot pin 41.Pivot pin 41 is formed under the situation of first embodiment 11 on the partition wall 39 that is arranged in the housing 13.Under second embodiment, 12 situations, it is formed on one's body 13 of the housings.In this pivot pin 41, constructed a slot 43, wherein mounted a end into this helical spring 33.The other end of this helical spring 33 is mounted in the edge 37 of the first side wall 35 of rolling wheel 25 in the corresponding receiving structure 45 (contrast Figure 11 and 12).

Two leads 47,49 of twisted wire cable 27 are penetratingly imported by second sidewall 36 of rolling wheel 25, and are connected on the self-cleaning contact 31.4 self-cleaning contacts 31 are set altogether.Have two self-cleaning contacts to be positioned on the primary importance on the lip-deep diameter of sidewall 36 in these self-cleaning contacts respectively, and wherein two be positioned on the second place of one on this diameter with respect to rotation 30 and primary importance symmetry.

The self-cleaning contact 31 that is connected with first lead 47 is positioned on first spacing with respect to rotation.The self-cleaning contact 31 that is connected with second lead 49 is positioned on second spacing with respect to rotation 30.In housing 13, be adjacent to settle a contact disc 51 with a first surface 53 and a second surface 55 with rolling wheel 25.First surface 53 rests on second sidewall 36 of rolling wheel 25.This contact disc 51 carries an inside on first surface 53 cunning is led the cunning of a contact ring 57 and an outside and is led contact ring 59.These contact rings 57,59 are connected with electronic devices and components 21.Inner contact ring 57 has a less mean radius, and this mean radius is consistent to first spacing of rotation 30 with self-cleaning contact 31.The contact ring 59 of described outside has a bigger mean radius, and this mean radius is consistent to second spacing of rotation 30 with self-cleaning contact 31.The first surface 53 that is connected from the contact ring 59 of outside to electronic devices and components 21 is guided.Contact ring 57 internally is guided to being connected on the second surface 55 of electronic devices and components 21.These connections are directed into electronic devices and components 21 unceasingly from the edge of contact disc 51 housing wall, that is to say, in the situation of first embodiment 11 by a relatively large distance round rolling wheel 25 edges, yet in the situation of second embodiment 12 on the distance of very short through components and parts 21.

Exist in addition to be arranged on mechanism in the housing 13 and that run through extension by housing 13 discharge so that can overcome the spring force of helical spring 33 with rolling wheel 25 brakings on many turned positions.These mechanisms comprise a drag knob 61, and it runs through this housing 13 on the rotation 30 of rolling wheel 25, and can not reverse in housing 13 ground and can overcome the spring force of a spring 63 in the axial direction and support movably.This drag knob 61 flexibly is bearing on the pivot pin 41 by this spring 63.Structure one wheel hub 65 on rolling wheel 25, and in wheel hub 65, on outstanding hub head 69, a snap surface 67 is set.This drag knob 61 can be supported in wheel hub 65 rotationally and axially movably.This drag knob can be in the axial direction in wherein occupying different position on two functions.On drag knob 61, construct snap projection 71, its can with snap surface 67 mating reactions.Overcome on the bulged-in position of spring force one, this drag knob 61 supports rotationally with respect to rolling wheel 25.If it is extruded to an application position by the spring force of spring 63, then the active force by helical spring 33 make snap surface 67 on rolling wheel 25 be extruded to the contacting of snap projection 71 brakings in.Therefore, rolling wheel 25 overcome helical spring 33 spring force be braked.

But the snap projection 71 on drag knob 61 also has a slidingsurface 73 that tilts, and its size in the axial direction is greater than the length that extends axially of hub head 69.If when this moment, rolling wheel was rotated by the pulling force on twisted wire cable 27, then hub head 69 touched and bumps against on these slidingsurfaces 73,, and therefore push drag knob 61 to overcome the spring force of spring 63 in the enterprising line slip of these slidingsurfaces.When drag knob 61 was flexibly submitted to this squeezing action by a kind of moving axially, twisted wire cable 27 promptly can be drawn out.But when making rolling wheel 25 toward back rotation owing to helical spring 33, then its braking is on snap projection 71; Except from this drag knob 61 of external compression.

Under first embodiment, 11 situations, the rotation 30 of this rolling wheel 25 is parallel to the direction of insertion orientation of contact plug 15.Therefore be used for direction of pull that cable 27 is pulled out direction of insertion perpendicular to electrical source importing device 11.Therefore under the situation of the electrical source importing device 11 that is inserted into, can on cable 27, apply pulling force, and do not have the danger that thus contact plug 15 is pulled out from supply socket.Because these two contact plugs 15 have been inserted into, electrical source importing device 11 can not rotate.

Under second embodiment, 12 situations, the rotation 30 of this rolling wheel 25 is perpendicular to the direction of insertion orientation of contact plug 15.Therefore the diameter of rolling wheel 25 is arranged in one or be parallel to a plane that axis limited by described two contact plugs 15.So then obtain the version of a kind of very flat about 15mm.

The components and parts of first embodiment 11 can also quite most of structure also be used among second embodiment 12 in the same manner.Therefore just can make these two embodiment 11,12 and its embodiment modification with seldom additional member.Difference mainly is as follows:

Under the situation of electronic devices and components 21, must differently dispose independent member, therefore need two differentiated slightly series, so that can construct described two embodiment 11,12 and its flexible program.The partition wall 39 of first embodiment 11 is discoidal, and is loaded with pivot pin 41 on a side, and is loaded with a bearing 75 that is used for electronic devices and components 21 on other side.The partition wall (not shown) of second embodiment 12 only is loaded with one and is used for the bearing of electronic devices and components 21, or can generally be removed.Therefore partition wall and bearing and a housing parts are configured to a kind of single piece.This pivot pin 41 is built on the housing parts then, and needs three housing parts.These housing parts are exactly insert 77, end part 78---being provided with described pivot pin 41 and cover piece 79 on it---, and drag knob 61 penetratingly passes this cover piece.Different therewith two housing parts that is insert 81 and the cover pieces 83 of only needing in first embodiment 11.And under the situation of these two embodiment 11,12,51 connector is different structure setting from electronic devices and components 21 to contact disc.

According to two housing parts 78,79 of electrical source importing device 12 needs of second embodiment to be used for rolling wheel body 19.When the bearing 32 that is used for low pressure plug 29 must be set on two parts, the advantage that has like this is, only these two members 78,79 must be manufactured to a plurality of modification, so that make the bearing 32 that is used for low pressure plug 29 adapt to the low pressure plug 32 of corresponding construction form.Under the situation of first embodiment 11, can be for this identical reason regulation, housing 13 is constituted by three housing components equally.Therefore the 3rd housing component 82 for example constitutes described partition wall 39, and is formed in the housing wall in the transitional region of seam of through cover piece 83, and is disposed between insert 81 and the cover piece 83.

Therefore not only first and also under the second embodiment situation this housing 13 constituted first housing parts 77 or 81 and two housing parts 78,79 or 82,83 compositions that constituted 32 1 halfbodies of bearing respectively that insert body by one.

The present invention's essential characteristics relates to described bearing 32 and is arranged in these two the described embodiment modification.Bearing 32 is being formed on the housing 13 on the pull-out direction of twisted wire cable 27.The pull-out direction of twisted wire cable 27 is located substantially on one first tangent line 85 of rolling wheel 25.Bearing 32 is positioned partially between second tangent line 87 and rolling wheel 25 of relative these first tangent line, 85 quadrature arrangement of rolling wheel 25.Therefore can be with the area applications between these two tangent lines 85,87 and the rolling wheel 25 in bearing 32, thus realize a kind of very little version of this charging device.Because this arrangement of bearing 22, then at every turn at the twisted wire cable by fully under situation about rising, 29 of low pressure plugs are pulled in the bearing 32.Because set, by means of its spring tension that twisted wire cable 27 can be retracted, low pressure plug 29 also can promptly be fixed under the situation of the mechanism on not being snapped into bearing and plug and remain in the bearing.

Twisted wire cable 27 is penetratingly guiding between two halfbodies of bearing 32.This twisted wire cable penetratingly extends by bearing along first tangent line 85 to rolling wheel.Therefore cable 27 when pulling out, rolling wheel 25 is not being taken place or is taking place hardly in the bending of leaving position 89 in cable 27.
