Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are done concrete description:
The utility model is used for the shock preventing protector of electric of supply socket or transducer; comprise protective cover 1, with loam cake 2, the two poles of the earth double-purpose closing door 3 and/or three flat closing door 4 and springs 5 of protective cover 1 snapping; described closing door and spring are placed in the space that is surrounded by protective cover 1 and loam cake 2, correspond respectively to double-purpose closing door 3 and three flat closing doors 4 in the two poles of the earth on protective cover 1 and the loam cake 2 and are provided with corresponding hole (referring to Fig. 2, Fig. 3, Fig. 6 and Fig. 7).The utility model can be provided with a closing door separately, also can two closing door combinations be provided with, and present embodiment is set to example with the two poles of the earth double-purpose closing door and three flat closing door combinations and describes.Referring to Fig. 1, Fig. 1 is the inside assembled relation schematic diagram of present embodiment.Referring to Fig. 2 and Fig. 4, Fig. 2 is a present embodiment superstructure schematic diagram simultaneously, and Fig. 4 is present embodiment the two poles of the earth double-purpose closing door structural representations.The shock preventing protector of electric of present embodiment comprise protective cover 1, with loam cake 2, the two poles of the earth double-purpose closing door 3, three flat closing doors 4 and two springs 5 of protective cover 1 snapping, double-purpose closing door H end in the two poles of the earth withstands on protective cover 1 inboard, the F end is withstood by spring 5.Loam cake 2 is provided with boss c2 with the corresponding position of boss c1 of the two poles of the earth double-purpose closing door 3, and during non operating state, c1 is stuck on the c2, and this two poles of the earth double-purpose closing door can't move.When plug inserts, the two poles of the earth double-purpose closing door 3 is pushed a bit of distance downwards, c1 is separated from the buckle of c2 and moves, because of c1 is a band inclined-plane boss, so along with the insertion of plug, move inward gradually and compress spring 5, after moving to certain distance, the two poles of the earth double-purpose closing door 3 gets out of the way jack fully, and plug just can insert; When plug is extracted, since the reset response of spring 5, the two poles of the earth double-purpose closing door 3 homings; When one pole inserts, because the two poles of the earth double-purpose closing door 3 is one-sided stressed, based on its translation downwards of lever principle, thereby boss c 1 can't break away from the buckle of boss c2, so the time the two poles of the earth double-purpose closing door 3 can't move, jack can't be opened, thereby the danger of getting an electric shock when having avoided one pole to insert.In order to realize the purpose of electrocution-proof protection better; on the two poles of the earth double-purpose closing door 3, also be provided with gear block d2; be provided with gear block d1 (referring to Fig. 3, Fig. 4) at protective cover 1 and the corresponding position of double-purpose closing door gear block d2, these the two poles of the earth; at regular intervals between this gear block d1, the d2; do not influence moving of the two poles of the earth double-purpose closing door 3; but one pole plays position-limiting action when inserting, and can assist boss c2 further to limit one pole and insert.Location when realizing 3 assemblings of this two poles of the earth double-purpose closing door better, loam cake 2 is installed corresponding position with the two poles of the earth double-purpose closing door 3 and also is provided with gear muscle b, and this gear muscle b locatees (referring to Fig. 2) when being used for 3 installations of the two poles of the earth double-purpose closing door.
Referring to Fig. 5, Fig. 5 is three flat closing door structural representations of present embodiment.It is inboard or at the N utmost point, the L utmost point of this three flat closing door 4 gear muscle a1 is set respectively that the M of this three flat closing door 4 end withstands on protective cover 1; at loam cake 2 corresponding sites gear muscle a2 is set; three flat closing doors 4 are withstood on the gear muscle a2 of loam cake 2 by gear muscle a1; the K end is withstood by spring 5; be the K end that spring 5 one ends withstand on three flat closing doors 4, spring 5 other ends withstand on the F end of the two poles of the earth double-purpose closing door 3.Three flat closing door 4 usefulness E represent ground wire (the E utmost point), L represents live wire (the L utmost point), N represents zero line (the N utmost point), the E utmost point of this three flat closing door 4 is provided with the boss on band inclined-plane, for the E utmost point drives, this three flat closing door 4 just can move inward compression spring 5 when promptly having only the E utmost point to insert, after moving a certain distance, closing door is opened, and plug inserts; When plug is extracted, since the reset response of spring 5, three flat closing door 4 homings.When one pole inserts the N utmost point or/and during the L utmost point, three flat closing doors all can't move, jack can't be opened, thereby the danger of getting an electric shock when having avoided one pole to insert.Simultaneously, above-mentioned two kinds of closing door structures can prevent that also foreign matter from entering in the socket.
During the non-insertion state of latch, double-purpose closing door 3 and three flat closing doors 4 in the two poles of the earth are contained between a2, the b retaining muscle structure by two springs, 5 tops, and are in charged jack guard mode.During the one pole latch application of force, the two poles of the earth double-purpose closing door 3 can't be opened because the lever principle of V-type mechanism is blocked by boss c2.When the two poles of the earth latch inserted simultaneously, the two poles of the earth double-purpose closing door 3 moved down certain distance and overcomes two boss c2 effects back and opens to a side.Three flat jacks drive for the E utmost point.The rear enclosed door extracted by plug because the effect of spring 5 recovers original closed position.The utility model can be used for combination bore form socket, the transducer in double-purpose hole, the two poles of the earth and one three flat hole.The utility model can use separately, also can be a plurality of as required serial connections use (referring to Fig. 6), or a plurality of and connect use (referring to Fig. 7).
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
