Embodiment
Below in conjunction with embodiment and contrast accompanying drawing and describe the present invention in detail.
Desk-top or the wall type safety electric shock-prevention socket of two holes shown in Fig. 1~7, three holes or combination/mixing, comprise base 26, be arranged on two, three of base 26 with the corresponding live wire of number of poles, zero line contact sleeve and termination, and with the shell 32 that has two holes 33,34, three holes, 37,38,41 jacks of base 26 adapteds.
Live wire, the zero line contact sleeve comprises conductive metal sheet 7,8,27, be arranged on conductive metal sheet 7,8, above or below in the of 27 and two ends are installed in four chute A4-A5 of base 26, B4-B5, C4-C5, insulation slide block 9 in the D4-D5,10,11,12, be positioned at insulation slide block 9,10,11,12 and base 26 between spring 17,18,19,20, be installed on the base 26 two switch hard contact sheets 1 as the two-way switch device, 3,13,2,4,14, be positioned at switch hard contact sheet 1,3,13,2,4,14 and base 26 between spring body 21,22,23, and be installed in switch hard contact sheet 1,3,13,2,4,14 with elastomer 21,22, insulation jacking block 15 between 23.
Conductive metal sheet 7,8,27 is connected with switch hard contact sheet 1,3,13,2,4,14 with energising indication component 24,25 by lead 5,6 respectively.Switch hard contact sheet 1,3,13,2,4,14 is connected with power firestreak, zero line respectively.
Base 26 is provided with button control piece 16, the corresponding through hole 35,39 that is provided with as the push-button switch hole between the jack of shell 32, and the top of button control piece 16 slides up and down at through hole 35,39.
Button control piece 16 is provided with and corresponding some A1, B1 of the slide block 9,10,11,12 that insulate, draw-in groove point A2, B2, C2, the D2 that C1, D1 coincide.
Base 26 is provided with energising indication component 24,25, the shell 32 corresponding energising indicator holes 36,40 that are provided with, and the energising indication component is installed in two spring hole scokets energising indicator hole 36 or the Three-hole socket energising indicator hole 40.
The safety electric shock-prevention socket of this embodiment is in the disconnected state of many safety locks when not inserting electrical appliance.When the live wire plug 29 of plug 28, zero line plug 30 insert the conductive metal sheet 7,8 of sockets, because plug pole piece 29,30 is under slotting power effect, the slide block 9,10,11,12 that will insulate is pushed both sides respectively to, makes the A1 point of insulation slide block 9 and the A2 point release of button control piece 16; The B1 point of insulation slide block 10 and the B2 point release of button control piece 16; The C1 point of insulation slide block 11 and the C2 point release of button control piece 16; The D1 point of insulation slide block 12 and the D2 point release of button control piece 16, along with deeply pressing down of plug 28, its surface fully contacts with the top of button control piece 16, force button control piece 16 to promote spring or elastomeric objects 23, jacking block 15 and switch hard contact sheet 13,14, thereby make 2,4 connections of 1,3 connected sum switch hard contacts of switch hard contact sheet sheet.
Because switch hard contact sheet 3 is connected with conductive metal sheet 7 by lead 5; Switch hard contact sheet 4 is connected with conductive metal sheet 8 by lead 6, thereby realizes power turn-on.Otherwise when plug 28 was extracted, because plug surface separates with the top of button control piece 16 at first, button control piece 16 was subjected to the effect of spring 21,22,23 power to begin to reset, and switch hard contact sheet 1,3,13/2,4,14 is at first disconnected.Owing to be subjected to the position-limiting action that A3, B3, C3, D3 are ordered on the base 26, button control piece 16 will stop motion at certain altitude, promptly A2, B2, C2, the D2 groove of button control this moment piece 16 overlap with A4, B4, C4, the D4 groove of base 26, moreover, insulation slide block 9,10,11,12 is subjected to the effect of spring 17,18,19,20 power to begin to reset, and makes the A1 point of insulation slide block 9 and the A2 point self-locking of button control piece 16; The B1 point of insulation slide block 10 and the B2 point self-locking of button control piece 16; The C1 point of insulation slide block 11 and the C2 point self-locking of button control piece 16; The D1 point of insulation slide block 12 and the D2 point self-locking of button control piece 16 return to initial condition.
Protection against electric shock process of the present invention is as follows:
When smallclothes conducting objects such as finger or copper wire, iron nail, key are inserted any hole of conductive metal sheet 7,8 of socket or diplopore, because its volume is little, can't push insulation slide block 9,10,11,12 to both sides, the A2 point self-locking of the A1 point of the slide block 9 that promptly insulate and button control piece 16; The B1 point of insulation slide block 10 and the B2 point self-locking of button control piece 16; The C1 point of insulation slide block 11 and the C2 point self-locking of button control piece 16; The insulation D1 point of slide block 12 and the D2 point self-locking of button control piece 16, thus make whole button control piece 16 be in self-locking state, switch hard contact sheet 1,3,13/2,4,14 is in off-state, can energized, thus reach the purpose of protection against electric shock.
If sheet metal is inserted the single hole of socket conductive metal sheet 7 or 8, although sheet metal can be with insulation slide block 9,11 or 10,12 push both sides to, but the insulation slide block has one group to be in self-locking state all the time, promptly insulate B1 point and the B2 point self-locking of button control piece 16 and insulate the D1 point of slide block 12 and the D2 point self-locking of button control piece 16 of C1 point with the C2 point self-locking of button control piece 16 or the slide block 10 that insulate of the A2 point self-locking of the A1 point of slide block 9 and button control piece 16 and insulation slide block 11, thereby make whole button control piece 16 be in self-locking state, switch hard contact sheet 1,3,13/2,4,14 are in off-state, can energized, still reach the purpose of protection against electric shock.
If sheet metal is inserted the diplopore of socket conductive metal sheet 7 and 8, though sheet metal can be pushed insulation slide block 9,10,11,12 to both sides, make it be in released state, but button control piece 16 is under the effect that does not have extraneous pressure, switch hard contact sheet 1,3,13/2,4,14 still is in off-state, can energized, reach the purpose of protection against electric shock.
Can be learnt by accompanying drawing 6,7,8: Three-hole socket safety electric shock-prevention process is identical with the process of two spring hole scoket safety electric shock-preventions.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention; make some alternative or obvious modification that are equal to without departing from the inventive concept of the premise; and performance or purposes are identical, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
