Abstract
The utility model relates to a bipolar protective door. A groove hole adapted with a grounding pin of a three-pole plug is arranged at the middle part of a main body, oblique tables adapted with pins of a bipolar socket are symmetrically arranged at the two sides of the groove hole, and each oblique table is inclined from the first side edge to the inner part of the main body; on the surface opposite to the oblique tables, the main body is provided with sliding grooves in parallel at the two sides of the groove hole. As the sliding grooves are used, the contact area between the bipolar protective door and a base of the socket is reduced, the resistance is lowered, the sliding is easier to be stable, and the safety of the socket is improved as well. As the groove hole provides a channel for other plugs, the bipolar protective door can be used with other protective doors in a compatible manner, so as to greatly reduce the volume and size of the socket, and reduce the use and cost of materials, thereby leading the socket to meet the requirements of every country and obtain the CCC certificate.

[embodiment]
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by embodiment of the present utility model is described in detail.
The two poles of the earth shutter is arranged between the panel and base of socket.Fig. 1 is the structure vertical view of a two poles of the earth shutter among the embodiment, and Fig. 2 is the upward view of a two poles of the earth shutter among the embodiment.In conjunction with Fig. 1 and Fig. 2, this two poles of the earth shutter 10 comprises main body 110, sloping platform 120 and is arranged on slotted eye 130 on the main body 110.
The middle part indent of the second side 114 relative with first side, sloping platform 120 place 112 forms location notch 150, is used for ccontaining elastic component.Elastic component can be symmetrically arranged two, also can be in the middle part of being arranged on along slotted eye 130 extended lines.Can be provided with positioning boss 140 in the location notch 150, be the elastic component location.When elastic component was spring, an end of spring was set on the positioning boss 140.
In the one side of main body 110 socket object bases, the parallel chute 250 that is provided with indent in the both sides of slotted eye 130.On this face, can also below chute 250, be provided with protection groove 260 perpendicular to chute 250.
Fig. 3 is the scheme of installation of the two poles of the earth shutter among the embodiment.In conjunction with Fig. 1 to Fig. 3, among this embodiment, socket is a multi-purpose socket, and it has the function of the two poles of the earth and three pole sockets.
Socket comprises panel 310 and base 320.Panel 310 is provided with the two poles of the earth jack and three utmost point jacks.The earth jack 312 of three utmost point jacks is positioned at the centre of the two poles of the earth jack L utmost point 314 and the N utmost point 316.Base 320 is provided with two parallel sides and protrudes from the slide rail 322 of base 320.The centre of slide rail 322 1 ends is provided with postive stop baffle 324.Both sides perpendicular to slide rail 322 are provided with protection step 326 simultaneously, and its quantity and position are corresponding with protection groove 260.
The two poles of the earth shutter 10 is arranged between socket panel 310 and the base 320.First side 112 is spacing near postive stop baffle 324.Elastic component is located between location notch 150 and base 320 sidewalls.If also have other shutters, then elastic component is located between location notch 150 and other shutters.Sloping platform 120 be positioned at the two poles of the earth jack L utmost point 314 and the N utmost point 316 under, directly over the two poles of the earth conductions sleeve, between jack and conduction sleeve, form interlayer, when inserting plug, do not play a protective role.Slide rail 322 cooperates with the chute 250 of the two poles of the earth shutter 10, forms two slide guide structures, and the contact area of dwindling the two poles of the earth shutter 10 and base 320 reduces resistance, makes its slip be more prone to stable.Slotted eye 130 is corresponding between earth jack 312 and the slide rail 322, for the ground pin of three-terminal polarized plus plug provides passage, realizes the multipurpose of socket, reduced the volume and the size of socket.
The course of work is as follows:
Elastic component is initially in contraction state, and the elastic force of its formation makes the two poles of the earth shutter 10 closely contact with base postive stop baffle 324, and sloping platform 120 covers the two poles of the earth conduction sleeve under it, slotted eye 130 corresponding earth jacks 312.When the two poles of the earth plug inserted, pin was descending along the inclined-plane of sloping platform 120, promoted main body 110 and moved to the elastic component direction along slide rail 322, exposed the two poles of the earth conduction sleeve, and plug can be inserted.After plug was extracted, the elastic force of elastic component promoted the two poles of the earth shutter 10 and gets back to the origin-location, relies closely with postive stop baffle 324, and the sleeve that again the two poles of the earth conducted electricity covers.
When using three-terminal polarized plus plug, its ground pin passes slotted eye 130 can directly enter corresponding sleeve, is not subjected to the influence of the two poles of the earth shutter.
When the one pole plug inserted, the monolateral compressing sloping platform 120 of plug formed downward pressure, and main body 110 serves as the stressed rotation of axle with slide rail 322, and protection step 326 snaps in protection groove 260.Since protect step 326 perpendicular to slide rail 322, so sloping platform 120 can not produce slip, thus the insertion of prevention one pole plug.
Above-mentioned the two poles of the earth shutter has the socket box of the two poles of the earth shutter, by using chute, reduces the contact area of the two poles of the earth shutter and socket base, reduces resistance, makes its slip be more prone to stable, has improved the fail safe of socket.Slotted eye can use the two poles of the earth shutter with other shutters are compatible for other plugs provide passage, thereby greatly reduces the volume and the size of socket, has reduced the use and the cost of material, makes socket can satisfy each national requirements, obtains the authentication of CCC.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
