Abstract

An electrical equipment transducer socket relates to a socket used for transferring of the electrical equipment. The socket includes a bearing box and a box cover, wherein the bearing box has an internal conducting strip, an external conducting strip, a heat insulation head, a spring, a partition board, a binding post and various jacks therein; the box cover has jacks corresponding to various jacks in the bearing box. The utility model designs jacks of different forms and with large contact area according to plugs of different types of the electrical equipment, which is able to meet the need of plugs of different equipment both at home and aboard and achieves the specific hole for specific use. The heat insulation head is provided outside the spring device, which makes the heat of the plug not be transmitted to the spring so that the spring can keep permanent elasticity to guarantee that the two conducting strips keep sufficient elasticity at any moment and are able to firmly clamp the plug, which solves the problems of bad contact and being easy to fall off between the plug and the socket. The utility model has simple and reasonable structure, specific hole for specific use, large electric conducted area, non heat generation and non deformation; the plug is fixed and not easy to fall off after being inserted. The utility model is provided with safe use, long service life, large capacity and wide range of application.

Description

A kind of electrical equipment switching mechanism socket

Technical field the utility model relates to a kind of socket that is used for the electrical equipment conversion.

The socket that background technology is sold and used on market at present, its core position conducting strip all is main material with the brass band, form through mechanical-moulded riveted joint, part producer has adorned spring to increase the pressure of conducting strip to the plug conducting position on the conducting strip of socket, reduce the contact resistance of plug and socket conducting position, guarantee its reliable contact, this measure has reduced the generation because of the loose contact damaged condition of plug and socket to a certain extent, but because of there not being heat-proof device, excessive in case load, temperature is too high, spring is heated and reduces or lose elasticity, increase the contact resistance of plug and socket conducting position, so poor circulation causes plug at last, the damage of socket and power consumption equipment.

Socket on the market has flat now, circle, the side, flat having is parallel, there are 60 °, round has diameter big, has diameter little, has nothing in common with each other, but use more in the homogeneous hole, and conductive area is little, and it is little with the contact area of plug to be in operation, loose contact makes the conducting strip heating of plug portion, oxidation, distortion, follow the string, can not return after opening etc., just produce loose contact when reusing, make plug uncontrollable between two conducting strips, cause the plug cisco unity malfunction that comes off, reduced result of use, serious made electricity consumption device damage, even cause property loss, loss of life or personal injury.

The summary of the invention the purpose of this utility model aims to provide a kind of dependable performance, simple in structure, safe in utilization, the life-span is long, capacity is big, the scope of application is wide electrical equipment switching mechanism socket.

The implementation of the utility model purpose is that kind electrical equipment switching mechanism socket comprises taking up box 10, lid, takes up inlet wire binding post 2, ground connection binding post 17, interior conducting strip 1, outer conducting strip 3, jack, spring are housed in the box.Outer conducting strip links to each other with interior conducting strip, and inside and outside conducting strip has jack, and lid has corresponding jack.Inlet wire binding post 2 is formed by interior conducting strip and binding post riveted joint.The special-purpose jack multi-form, that contact area is big that is fit to various plug specials is arranged on the inside and outside conducting strip, and jack is withstood by the spring 9, the outer heat insulation top 6 that are contained in the spring housing 5.

The outer conducting strip 3 of the utility model, interior conducting strip 1 and on jack adopt mechanical-moulded copper spare.Inside and outside conducting strip 3 has the special-purpose jack that is fit to various plug specials, and jack is withstood by the spring 9, the outer heat insulation top 6 that are contained in the spring housing 5.The opposite side diameter of special-purpose jack, thickness be less than diameter, the thickness of plugs and sockets, guarantees combining and conductive effect of jack and plug, and the assurance plug does not come off.Outer heat insulation top 6 can separate the heat that produces between plug and socket, does not allow spring 9 be heated and follows the string.Left and right conducting strip by dividing plate 8 grades separately.

The special-purpose jack side of comprising inserts positioning jack 4, flat tripod earth jack 7, how with berrette file jack 11, two jiaos of jacks 14 of circle 18.33mm, flat two pin jacks 15, square triangle jack 12, two jiaos of jacks 13 of round 19mm.It is specially to external square toes three-pin plug that the side inserts positioning jack 4, and its effect is not ground connection but makes the plug firm position; Flat tripod earth jack 7 is for earthy; Inlet wire binding post 2 is connected each inlet wire with ground connection binding post 17; Many with flat tripod jack 11 in order to insert common flat three-pin plug, also can insert the flat three-pin plug of increasing; Circle 19mm two pin jacks 13 are specially inserted external a kind of round end Two-feet plug. and square tripod jack 12 also is to aim at external a kind of side's three-pin plug; Circle 18.3mm two pin jacks 14 are inserted two pin round end plugs; Flat two pin jacks 15 are used for two pin flat plugs.Conductive connecting line 16 can guarantee the conductive effect of interior conducting strip, outer conducting strip better.

The area of the utility model jack is big, and bigger 5 times than the area of existing berrette file jack, flat two jiaos of jacks as many areas with berrette file jack 11, flat two pin jacks 15, the area of other plugs is bigger about 10 times than the area of existing plug.Not only contact-making surface is big, and contact-making surface is thick, can carry the electric current of 10-40A, and is more much bigger than traditional 10A.

Because the special hole special use of the utility model jack, the contact area after plug inserts is big, adds the effect of spring force, makes the two keep good binding at any time.

The utility model simple and reasonable, special hole special use, conductive area greatly, do not generate heat, indeformable, insert the back firmly, the plug difficult drop-off, safe in utilization, long service life, capacity is big, the scope of application is wide.
