In combination with fig. 1, the embodiment of the utility model provides a safety socket, it includes base 1, set up zero line jack 12, live wire jack 13 in base 1 and be equipped with first metal baffle 2 and the second metal baffle 3 of through-hole (not shown in the figure), wherein, first metal baffle 2 and second metal baffle 3 set up respectively in zero line jack 12 and live wire jack 13 one side of keeping away from the drill way, safety socket still includes: the accommodating space 14 is arranged on one side, away from the orifice, of the first metal baffle plate 2 and the second metal baffle plate 3 in the base 1; safe conduction mechanism, it includes: a connecting rod assembly (such as, but not limited to, the first connecting rod 4 and the second connecting rod 6) at least partially disposed in the accommodating space 14, and having one end disposed corresponding to the through hole of the first metal baffle 2 and the other end disposed with a metal conductor 8 and conducted to the power supply live line L via the biasing member 7; and a support 11, the support 11 is fixed at the bottom of the accommodating space 14 and configured to support the connecting rod assembly, wherein in a non-working state, the metal conductor 8 and the second metal baffle 3 are in a separated state under the action of the biasing member 7; in a working state, the one end of the connecting rod assembly is pushed to move towards the bottom of the accommodating space 14 to drive the other end to move towards the second metal baffle 3, so that the metal conductor 8 is in contact conduction with the second metal baffle 3.

Based on the foregoing the utility model discloses a safety socket can effectively avoid only inserting under the condition of zero line jack 12 or live wire jack 13 alone, though with zero line N or power supply live wire L electrical property intercommunication, however, does not form effectual conduction circuit, and then when the user inserts zero line jack 12 or live wire jack 13 with the conductor, can not produce harm to personal safety. Further, the safety socket can be matched with a common plug for use, so that the circuit is prevented from being conducted in an abnormal working state (for example, only the neutral wire jack 12 or the live wire jack 13 is inserted, a non-plug wire is inserted into the jack, and the like), and the operation safety is ensured. Specifically, for example, in the case that the wire is inserted into the neutral wire insertion hole 12, the one end of the connecting rod assembly cannot be pushed to move toward the bottom of the accommodating space 14, and then the other end of the connecting rod assembly cannot move toward the second metal baffle 3, so that the metal conductor 8 and the second metal baffle 3 cannot be in contact conduction, and thus, abnormal circuit conduction is avoided, and the safety of operation is ensured.

In some embodiments, the connecting rod assembly comprises a first connecting rod 4 and a second connecting rod 6, at least part of the first connecting rod 4 is arranged through the through hole of the first metal baffle 2, one end of the second connecting rod 6 is pivotably connected with the first connecting rod 4, the other end is provided with a metal conductor 8 and is communicated with the power supply live wire L through a biasing member 7, and the second connecting rod 6 is supported by a support member 11 between the two ends; for example, in the present embodiment, the pivotal connection may be achieved by the pivot 5; after the plug 9 is inserted into the safety socket, at least the first connecting rod 4 can be effectively pushed, for example, the shape of the through hole can be set to be correspondingly matched with the shape of the pin 10 of the plug 9, so that the pin 10 of the plug 9 can be effectively inserted into the through hole, the first connecting rod 4 is pushed to move, and the other end of the second connecting rod 6 is driven to move towards the second metal baffle 3; or, one end of the first link 4 extends out of the through hole, so that after the plug 9 is inserted into the safety socket, the "foot 10" of the plug 9 can directly push the first link 4, and the operation action is repeated; the positional relationship between the through hole and the first link 4 is not further limited, and can be adjusted accordingly as required.

In some embodiments, the second link 6 is disposed in the accommodating space 14, so as to fully protect the second link 6 from the accommodating space 14, and the size of the accommodating space 14 can be adjusted according to the overall size of the safety socket, the distance between the opening and the end of the first link 4, the length of the first link 4, and other parameters.

In some embodiments, the support 11 includes a wedge-shaped block as a fulcrum of the second link 6, and the second link 6 realizes a prying action by using the wedge-shaped block as the fulcrum under the action of the force of the first link 4, and enables one end of the second link 6 to abut against the second metal baffle 3, thereby realizing current conduction.

In some embodiments, the wedge block is disposed at a midpoint position along the length direction of the second link 6, but the wedge block may also be disposed at other different positions, for example, at a position of one third or two thirds of the length of the second link 6, and the wedge block may be correspondingly disposed according to the size of the accommodating space 14, and is not further limited herein.

In some embodiments, the biasing member 7 is a spring, and in the non-operating state, the spring is in a stretching state to maintain the separation state between the metal conductor 8 and the second metal baffle 3; effectively avoid under the condition that live wire jack 13 was inserted to the metal wire mistake, because be in the disjunctor state between metal conductor 8 and the second metal baffle 3 and make the circuit be in the off-state, the circuit does not switch on promptly, and then plays the safety protection effect to the user.

In some embodiments, the metal conductor 8 is a metal block, and the surface facing the second metal baffle 3 is set to be an inclined surface so as to be in sufficient contact with the second metal baffle 3, so that the occurrence of a situation that the personal safety is endangered due to the generation of electric sparks caused by virtual connection and the like can be effectively avoided due to the sufficient contact.

In some embodiments, the metal conductor 8 may also be disposed obliquely so as to be in full contact with the second metal baffle 3, and this arrangement can save the relevant processes and cost for manufacturers, and by adjusting the inclination angle of the metal conductor 8, the surface of the metal conductor 8 can keep the same angle with the surface of the second metal baffle 3 after moving, so as to be in full contact.

For the convenience of understanding the operation mode of the safety socket in the embodiment of the present application, a brief description is made herein for the case where the safety socket is in the working state and the non-working state.

Under the non-operating condition, because the spring is to the tensile effect of metallic conductor 8 for metallic conductor 8 uses and is in the separation state between the second metal baffle 3, and because second metal baffle 3 does not set up the through-hole, makes even under the condition that the wire inserted live wire jack 13 alone, also can't form effectual intercommunication with the metallic conductor 8 in the accommodation space 14, and then under the condition of misplugging, realizes safety protection's effect.

Under operating condition, because two "feet 10" of plug 9 insert zero line jack 12 and live wire jack 13 respectively simultaneously to make "foot 10" that inserts zero line jack 12 promote first connecting rod 4 and move down, and exert the effort to second connecting rod 6, under leverage, the metallic conductor 8 that sets up at second connecting rod 6 one end supports with second metal baffle 3 and pushes against, and switches on through spring and live wire, forms effective circuit and switches on, makes the electrical equipment of being connected with plug 9 begin normal work.

Through being in the embodiment of the utility model provides an in set up accommodation space 14, link assembly and support piece 11, need not auxiliary structure, for example, the shutter effectively avoids leading to the difficult male problem of plug 9 because the shutter is narrow and small, simultaneously, need not to adjust the structure of plug 9, and then under the prerequisite of ensureing safety, still have the beneficial effect of commonality concurrently.
