Abstract
The utility model provides a safety socket which is provided with a body, wherein a plurality of clamping holes are formed in the body; insulation sheaths are arranged in the clamping holes; and the apertures of inner holes of the insulation sheaths are smaller than those of the clamping holes. By the safety socket, when the socket is mounted, the insulation sheaths are pushed into the clamping holes; at the moment, the outer diameters of the insulation sheaths are in tight fit with the inner diameters of the clamping holes; the apertures of the inner holes of the insulation sheaths are smaller than those of the clamping holes, so that the sizes of orifices of the clamping holes are indirectly reduced, and mis-contact of fingers of people is avoided; moreover, after the insulation sheaths are pushed into the clamping holes, a contact piece can extend into a central hole of each insulation sheath; to a certain extent, the contact piece can be guided and positioned; furthermore, a clearance between the contact piece and each clamping hole is reduced, so that leftward and rightward swinging of the contact piece is limited to a certain extent; and a plug and the socket can be successfully inserted.
Description
Technical field
The utility model relates to a kind of safety socket, is applicable in large electric current industrial connector.
Background technology
The industrial connector plug assembly in use will be in accordance with the using priciple of " socket is connected on mains side; during disconnection, plug must not be charged ", because socket is contained in power supply one side when mounted, for the larger connector of ampacity, the profile of its jack contact also increases thereupon, thereby in insulator, the screens hole of guiding jack contact also becomes very large, socket is still charged when not using, people's finger just might false touch screens hole and touch charged jack contact, thereby therefore the security incident of causing is necessary to improve.
The utility model content
The technical problem that the utility model solves: a kind of safety socket is provided, installing insulating sheath in the screens hole, the endoporus aperture of insulating sleeve much smaller than aperture, screens hole and finger can not pass endoporus, improved the security performance of socket.
The technical solution adopted in the utility model: a kind of safety socket, have body, be shaped with a plurality of screens holes on described body, described screens is provided with insulating sleeve in the hole, and the endoporus aperture of insulating sleeve is less than the aperture in screens hole.
Further, described insulating sleeve excircle is tapered, and the endoporus of insulating sleeve is stepped hole, and the small bore end of described stepped hole is positioned at the large end of insulating sleeve.
Further, described insulating sleeve adopts PBT to make.
The utility model is compared with prior art in after the socket installation pushing insulating sleeve the screens hole, this moment insulating sleeve external diameter and screens hole internal diameter tight fit, due to the endoporus aperture of insulating sleeve much smaller than aperture, screens hole, indirectly reduce the screens port size, avoided the misconnection of finger to touch; Simultaneously, after insulating sleeve pushes the screens hole, contact can extend in the centre bore of insulating sleeve, played to a certain extent the guiding positioning action of contact, and make gap smaller between contact and screens hole, limited to a certain extent swinging of contact, be beneficial to plug and socket smoothly to inserting.

Embodiment
Below in conjunction with accompanying drawing 1,2,3, a kind of embodiment of the present utility model is described.
A kind of safety socket has body 1, is shaped with a plurality of screens hole 2 on described body 1, be provided with insulating sleeve 3 in described screens hole 2, wherein, insulating sleeve 3 adopts PBT to make, and the endoporus aperture of insulating sleeve 3 can not be passed less than aperture and guarantor's finger in screens hole 2.Described insulating sleeve 3 excircles are tapered, and the endoporus of insulating sleeve 3 is stepped hole 4, and the small bore end of described stepped hole 4 is positioned at the large end of insulating sleeve 3.
The utility model has adopted the way in the screens hole 2 of containing on jack body 1, according to the size in screens hole 2, makes a corresponding cover insulating sleeve 3, this insulating sleeve is made torus, wherein, in it, hole dimension is little more than the screens hole dimension, and finger can not pass endoporus.In after the socket installation, insulating sleeve 3 being pushed screens hole 2, this moment insulating sleeve 3 with screens hole 2 tight fits, reduced the size of 2 ends, screens hole, avoided the misconnection of finger to touch; Simultaneously, after insulating sleeve 3 pushed screens hole 2, contact 5 can extend in the stepped hole 4 of insulating sleeve 3, has played to a certain extent the guiding positioning action to contact 5, be beneficial to plug and socket smoothly to inserting.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, thus all equivalence variations of being done with the described content of the utility model claim, within all should being included in the utility model claim scope.
Claims (3)
