Embodiment
Below in conjunction with embodiment and contrast accompanying drawing and specify the present invention.
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 metal spot films 1 as the two-way switch device; 3; 13; 2; 4; 14; Be positioned at switch metal spot film 1; 3; 13; 2; 4; 14 and base 26 between spring body 21; 22; 23; And be installed in switch metal spot film 1; 3; 13; 2; 4; 14 with elastomer 21; 22; Insulation jacking block 15 between 23.
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 metal spot film 13,14, thereby make switch metal spot film 1,3 select 2,4 connections of connected sum switch metal spot film.
Because switch metal spot film 3 is connected with conductive metal sheet 7 through lead 5; Switch metal spot film 4 is connected with conductive metal sheet 8 through 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 received the effect of spring 21,22,23 power to begin to reset, and switch metal spot film 1,3,13/2,4,14 is at first broken off.Owing to receive 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 receives 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 following:
When smallclothes conducting objects such as finger or copper wire, iron nail, key are inserted any hole or the diplopore of conductive metal sheet 7,8 of socket; 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; D1 point and the D2 point self-locking of button control piece 16 of insulation slide block 12, thus make whole button control piece 16 be in self-locking state, switch metal spot film 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; Slide block 9,11 or 10,12 is pushed both sides to although sheet metal can will insulate; 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 and the C2 point self-locking of button control piece 16 or the slide block 10 that insulate of the self-locking of A2 point and insulation slide block 11 of A1 point and button control piece 16 of slide block 9; Thereby make whole button control piece 16 be in self-locking state; Switch metal spot film 1,3,13/2,4,14 is 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; Slide block 9,10,11,12 is pushed both sides to though sheet metal can will insulate; Make it be in released state, but button control piece 16 is under the effect that does not have extraneous pressure, switch metal spot film 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 is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, make some alternative or obvious modification that are equal to; And performance or purposes are identical, all should be regarded as belonging to the scope of patent protection that the present invention is confirmed by claims of being submitted to.
