Embodiment
With reference to the accompanying drawings, describe the preferred embodiments of the present invention in detail.These embodiment only are used for being described more specifically the present invention, and scope of the present invention is not to be defined in these embodiment, and this is that the person of ordinary skill in the field is self-evident.
(the 1st embodiment)
Fig. 1 is the exploded perspective view of the insert row of one embodiment of the invention.As shown in the figure, the socket main body section 100 of the application's insert row is made of sub-body section 134 and upper body section 106, wherein, described sub-body section 134 is connected in power line, be equipped with the power supply connector 124 that inserts for plug splicing ear 14 (with reference to Figure 12), described upper body section 106 is formed with the circular port section 104 that inserts for plug.
Described upper body section 106 has for the hole of inserting main switch 128 and sub-switch 126.
Described sub-body section 134 has for the sub-body section earth terminal 120 that connects with the corresponding earth terminal of plug.
Between described upper body section and sub-body section 134, illustrate safety device.This safety device is made of upper circular lid and blade and lower panel.
Lower springs 116 is arranged between the guide hole 118 of the sub-body section that inserts for guiding cylindrical portion 112, provides elastic force between described sub-body section and safety device.In the both sides of circular lid 108, to the direction of the through hole of safety device 200 guide projections section 132 is installed, the guide member 136 that is formed with corresponding with it guide channel is installed on the circular port section 104 of upper body section 106.Shown in Fig. 2,3,6, safety device 200 comprises blade part 114 and safety device lower panel 130, wherein, described blade part 114 has the 1st blade 230 that is formed with rake 214, so that when plug splicing ear 14 inserts, make blade part 114 to the direction rotation vertical with the direction of insertion of plug splicing ear, described safety device lower panel 130 is formed with the through hole 206 that connects for the plug splicing ear.
As shown in Figure 3, guide member 136 (with reference to Fig. 1) is in the situation that plug does not insert, support portion 212 by described the 1st blade 230 of blade part 222 covers, when splicing ear inserts, the support portion 212 of described the 1st blade is rotated as shown in Figure 5, guide member 136 is opened, and safety device 200 can move to the direction identical with the direction of insertion of splicing ear 14.
Fig. 2 illustrates the topsy-turvydom of this safety device 200.Safety device 200 of the present invention comprises circular lid 228, blade 222, safety device bottom 202, wherein, described circular lid 228 is formed with the through hole 110 (with reference to Fig. 1) that connects for plug splicing ear 14, has guiding cylinder 210, described blade 222 has the 1st branch 230 that is formed with rake 214, so that when plug splicing ear 14 inserts, make blade 222 to the direction rotation vertical with the direction of insertion of plug splicing ear 14, described safety device bottom 202 is formed with the through hole 206 that connects for plug splicing ear 114.
The 1st blade 230 of blade part 222 has a side and is guided the 1st blade support portion 212 that jut 232 supports, safety device 200 comprises leaf spring 218, when leaf spring 218 is removed insertion at plug 10, make the 1st blade support portion 212 of blade part 222 again return to guide projections section 232.Circular lid 228 has makes the fixing spring jut 220 of leaf spring 218 and the leaf spring support portion 224 of support blade spring 218.Blade part 222 can be along axle 410 (Fig. 4) rotation, and the cap 216 of the 2nd blade 226 covers the earth terminal pilot trench 406 (with reference to Fig. 4) of bottom earth terminal pilot trench 204 and circular lid in the situation without the splicing ear of plug.The rake 214 that Fig. 3 illustrates the 1st blade 230 covers the through hole 404 (Fig. 4) of splicing ear, the cap 216 of the 2nd blade covers the state of earth terminal pilot trench 406.
In this state, when the splicing ear of plug inserted, blade part 222 was to clockwise direction rotation Δ c (with reference to Fig. 5).With reference to Fig. 6 to Figure 10, this Principle of Rotating is described.
Fig. 6 is the A-A sectional view of Fig. 3 of one embodiment of the invention, is the figure that the segment difference section 602 that shows the rake 214 of blade is supported in the state of the circular lid 228 of safety device and locking.Wherein, rake 214 is connected in circular lid 228 owing to segment difference section 602 and can't rotates.
Fig. 7 is the sectional view of B-B of Fig. 3 of one embodiment of the invention, is the figure of state of the guide projections section 232 of the support portion 212 that demonstrates the 1st blade circular lid that is supported in safety device 200.
In this state, as shown in Figure 8, the splicing ear of plug inserts the through hole 404 of the circular lid 228 of safety device 200, contacts with the rake 214 of the 1st blade.
Wherein, if the splicing ear of plug further moves ahead and insertion and rake 214 is moved upward the Δ a that is equivalent to circular lid 228 thickness, then described rake 214 is removed clampings from circular lid 228, is in the state that can rotate freely.That is, as shown in Figure 9, the splicing ear 14 of plug further inserts by the through hole 404 of safety device 200, and the segment difference section 602 of described rake 214 unlocks with respect to the circular lid 228 of safety device, rotates to the left Δ c.
So after the rotation, as shown in Figure 5, the support portion 212 of described the 1st blade is to the direction of arrow, it is the clockwise direction rotation, originally the guide member 136 (with reference to Fig. 1) that was blocked by the support portion 212 of the 1st blade is thus opened, and safety device 200 can move to the direction identical with the direction of insertion of splicing ear 14.In addition, the earth terminal pilot trench 406 of circular lid 228 is opened, and therefore, the earth terminal 120 of Fig. 1 is ready to be connected with the plug earthed terminal.Certainly, this through hole 214 and earth terminal pilot trench 406 capped or sealing under the common state that plug does not insert.
And this only opening could be realized when 2 splicing ears of plug insert simultaneously.Its reason be because, as shown in Figure 8, only have 2 rakes, 214 whole mobile Δ a after, blade 222 could rotate.
Figure 10 is the figure that shows the blade 222 that is inserted in sharf 410.The 1st blade 230 that is formed with rake 214 is configured to carry out as shown in the figure resilient movement (with reference to Fig. 8 and Fig. 9) when the splicing ear of plug inserts.Wherein, when the Δ a as circular lid 228 thickness of movable length Δ b and Fig. 8 was identical or larger, blade part 222 was in the state that can rotate freely.When 222 rotation of this blade part, the support portion 212 of the 1st blade 230 is rotated, thus guide member 136 (Fig. 1) open, safety device 200 can move to the direction identical with the direction of insertion of splicing ear 14.
Insert in the situation of power supply connector 124 (Fig. 1) at plug splicing ear 14, extremely shown in Figure 5 such as Fig. 2, when the circular lid 108,228 of safety device 200 is pressed, the plug splicing ear inserts the power supply connector, when plug splicing ear 14 is removed insertion from power supply connector 124, the circular lid 108 of safety device 200,228 elastic force by means of lower springs 116 (Fig. 1) return to the top position of circular port section 104, and guide member 136 seals again.If splicing ear 14 is removed connect, extract from the circular lid 108,228 of safety device 200 fully, namely, splicing ear 14 is extracted from the through hole 110,404 of splicing ear fully, so, and as shown in Figure 8, rake 214 by through hole 110,404 clampings, is in the lock state again.
