Abstract

The invention discloses a safety receptacle which comprises a panel, shells symmetrically arranged on the panel and used for fixing electrodes, and two electrode pieces fixedly installed on the shells, wherein the panel is provided with jacks which correspond to the electrode pieces. The safety receptacle is characterized by a key improvement that the electrode pieces are in integrally folded shapes; the main structure of each electrode piece is in a door shape; each left vertical edge is folded inwards by an angle and then extends upwards; each upwards extended part is parallel to each left vertical edge; the distance from the folded part to the bottom end of each right vertical edge is the same as the distance from the folded part to the top transverse edge of each main structure; each upwards extended part is matched with the right vertical edge to form a clamping part of each electrode piece; and the left and the right vertical edges of the electrode pieces are symmetrically provided with vertical slotted holes. The safety receptacle has the advantages that the contact area between the electrodes of a plug and the electrode pieces is increased by lengthening plane sections of the electrode pieces; and sealed external power supply and contacts are used for avoiding causing electric arcs when the plug is inserted in with loads, thereby the service life and the electricity safety of the plug and the receptacle are effectively guaranteed.

Description

Safety socket

Technical field

The present invention relates to a kind of socket, particularly a kind of safety socket.

Background technology

Socket is that a kind of convenience is with the direct-connected device of power consumption equipment and supply line; existing socket no matter be two holes or three holes; its electrode all is directly to be connected with the power line of supply line; can satisfy general user's user demand; the installation site that is installed in the socket on the wall commonly used is lower; and keep power supply state always; as long as power consumption equipment is inserted socket; power consumption equipment can be communicated with supply line; so; if have child or adult because of carelessness the object of conduction to be inserted one of them jack; will cause the generation of electric shock accidents, though the slide block that is used to protect socket is installed on the existing safety socket; do not have the effect of protection personal safety; the structure of the electrode of existing socket is a symmetrical structure on the one hand in addition, and the contact area between the copper sheet of both sides is less, is easy to generate electric arc when on-load is with plug insertion socket; thereby influence the useful life of socket and plug, also dangerous.

Summary of the invention

The invention provides and a kind ofly can guarantee safe in utilizationly, improve the safety socket in socket and plug useful life.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: safety socket, comprise panel, be symmetrically set in the housing that is used for fixing electrode on the panel and be fixedly mounted on two electrode slices on the housing, panel is provided with and the corresponding jack of electrode slice, its key improvements is: described electrode slice is a foldable integral shape electrode slice, its agent structure is the door type, the inside bending of vertical edges angle in left side extends upward later on, it is parallel with the left side vertical edges to extend upward part, the bending part is identical with the top cross back gauge of vertical edges bottom, right side and its agent structure, extend upward part and cooperate the retained part that constitutes electrode slice with the right side vertical edges, be arranged with vertical slotted eye on the left and right sides vertical edges of electrode slice, be symmetrical arranged crossfeed device and the locking device that is used for the enclosed-electrode sheet between the electrode slice.

Adopt the beneficial effect that technique scheme produced to be: the present invention is by the length of lengthening electrode plane section, increase the contact area between plug electrode and the electrode slice, the starting the arc in the time of not only can preventing to insert plug, can also increase the loaded current of socket, effectively guarantee the useful life of plug and socket; The present invention is also by adopting the mode of crossfeed conducting to power between two electrode slices of socket, and slotted eye is set on the electrode slice, with the supporting block that is provided with of slotted eye, when inserting plug, electrode slice is subjected to the promotion of plug and inwardly moves, drive the block motion in the time of the electrode slice motion, the balance staff affixed with block is rotated, the balance staff of rotation drives slide block movement, thereby connect first copper sheet and second copper sheet and give another one electrode slice power supply conducting, and the locking device that is arranged in the housing moves to the jack direction under the drive of balance staff, if only insert conductive body to single jack, slide block connects first copper sheet and second copper sheet is given another one electrode slice power supply conducting, and the locking device that is installed in simultaneously in second housing seals jack, prevents the generation of electric shock accidents.
