Abstract

The utility model discloses a safety socket with a protective door, which comprises a socket main body, a conductive body and a socket cover which is provided with jacks. The utility model is characterized in that an interlayer is arranged between the socket cover and the socket main body, a sliding piece for covering the conductive body is installed in the interlayer and a spring is connected between the sliding piece and the socket main body. The sliding piece is provided with a bevel on a part which corresponds to the jacks of the socket cover. The bottom surface of the sliding piece is provided with a convex rib. The inner wall of the socket cover is provided with two grooves on positions which correspond to the jacks. When a monopole is inserted, because of imbalance stress, one end of the sliding piece can sink along a hole of the conductive body and the other end can be tilted to be penetrated into the grooves on the inner wall of the socket cover. Consequently, the safety socket with a protective door prevents the sliding piece from moving backwards. At this time, inserted objects are blocked by the sliding piece and can not enter. The sliding piece can play the action of a protective door.

Description

The safety socket of band shutter

[technical field]

The utility model relates to supply socket, especially relates to a kind of safety socket with shutter.

[background technology]

Modern live and work all be unable to do without electric equipment, and electric equipment be unable to do without supply socket.Particularly universal contact receptacle is big because of its jack, and object is strayed into jack easily, even children's pinkie also can contact copper sheet easily.For safety, be provided with shutter, to prevent the electrode in child's finger touch jack and to avoid inserting the danger that charged jack causes electric shock because one pole appears in accidental misoperation the jack planted agent of supply socket.The socket of present band shutter places the jack inboard of socket with shutter, and shutter is being provided with the inclined-plane towards jack one side, and is provided with back-moving spring on the direction of motion.When plug insertion socket, the electrode of plug is pressed to the inclined-plane of shutter, stressed the moving upward of shutter and being opened.The shortcoming of this socket is to prevent effectively that one pole from inserting.And one pole can make power consumption equipment charged easily, or make another electrodes exposed when inserting, and causes danger.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of safety socket with shutter, and one pole can't insert, and the bipolar socket that is easy to open shutter when inserting simultaneously.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:

Provide a kind of safety socket to comprise the socket cover of socket main body, electric conductor, band jack with shutter, it is characterized in that: an interlayer is arranged between socket cover and the socket main body, the slide of one covering electric conductor is installed in this interlayer, be connected a spring between described slide and socket main body, slide is provided with the inclined-plane in the part corresponding to the jack of socket cover, and the bottom surface of slide is provided with the muscle of a projection; Be provided with two grooves corresponding to jack position on the socket cover inwall.

Further improvement in the technical proposal is:

Described groove cross section is a triangle.

Described slide has a cylindrical protrusion that is used for mounting spring.

Described socket is the two-phase socket.

Described socket is a three-phase socket, and described slide has a slot that extends to ground wire jack.

The beneficial effects of the utility model are: because a slide is installed between the utility model socket cover and the socket main body, be connected a spring between described slide and socket main body, slide is provided with the inclined-plane in the part corresponding to the jack of socket cover, is provided with two grooves corresponding to jack position on the socket cover inwall.When plug normally inserted, because the two poles of the earth or multipolely exert oneself simultaneously, plug was exerted pressure to the inclined-plane of slide, and slide is removed backward, and plug inserts smoothly; If one pole inserts; owing to use force unbalance, the other end of slide is owing to the support meeting perk of the muscle of projection is deep into groove on the socket cover inwall, thereby moves after stopping slide; insert object and be subjected to stopping of slide and can not enter this moment, and slide promptly can play the effect of shutter.

Below in conjunction with accompanying drawing the utility model is described further:

[embodiment]

See also Fig. 1 to 9:

A kind of safety socket with shutter of the utility model comprises the socket cover 2 of socket main body 1, band jack, the electric conductor (not shown) is arranged in the jack 3 of socket main body 1, between socket cover 2 and the socket main body 1 interlayer is arranged, one slide 4 is installed in this interlayer, be connected a spring 5 between described slide 4 and socket main body, spring 5 is installed on the cylindrical protrusion 6 of slide 4, slide 4 is provided with inclined-plane 41 in the part corresponding to the jack of socket cover 2, and the bottom surface of slide is provided with the muscle 42 of a projection; Be provided with two grooves 8 corresponding to jack position on socket cover 2 inwalls.

When plug normally inserted, because the two poles of the earth or multipolely exert oneself simultaneously, plug was exerted pressure to the inclined-plane 7 of slide 4, and slide 4 is removed backward, and plug inserts smoothly, and after plug was extracted, the elastic force of spring 5 resetted slide 4; If one pole inserts; owing to use force unbalance; the other end of slide is because the support meeting perk of the muscle 42 of projection is deep into the groove 8 on socket cover 2 inwalls; the end face of groove 8 moves after stopping slide 4; insert object and be subjected to stopping of slide 4 and can not enter this moment, plays the safeguard protection effect.

Shown in Fig. 6 is wherein a kind of groove 8 structures, also can take rectangle or other cross sectional shapes.

The utility model can be the two-phase socket, also can be three-phase socket.Fig. 1, Fig. 2 are slide 4 structure charts of two-phase socket; Fig. 3, Fig. 4 are slide 4 structure charts of three-phase socket, because the ground terminal shields, can insert at any time, so do not need to be provided with shutter.
