Description
Technical field
The utility model relates to appliance field, specifically, is that a kind of lengthening overlaps plug.
Background technology
Electronic product every day is along with our life, at present, plug is divided into three hole plugs and holes plug, it is to having three hole terminal blocks and holes terminal block, and in order to meet the diversity of function that terminal block uses, the terminal block on market normally three hole terminal blocks designs together with two hole terminal blocks, but the close together between three hole terminal blocks and two hole terminal blocks, design space is inadequate, when user uses a three hole plug, can not use two hole plugs simultaneously; When user uses two hole plugs, can not use three hole plugs, this design can not meet the demand of user simultaneously.
Secondly, user is at insertion plug or take out plug, and finger easily touches conductive metal sheet, and cause electric shock accidents, security performance is low.
In addition, those skilled in the art learns, the power output general standard of holes terminal block and three hole terminal blocks is 10 amperes, but general household electrical appliance electric current is to not 10 amperes, prove that holes terminal block and three hole terminal blocks can use simultaneously, namely terminal block uses holes plug and three hole plugs to be safe for general household electrical appliance simultaneously.
Moreover, the jack of terminal block in prior art, because of with plug Long-Time Service, user, when inserting plug, does not have the standard of location determination, and firmly uneven when making to insert plug, cause jack to be easily out of shape, even plug easily comes off.
In sum, need that a kind of structure is simple, fail safe good, difficult drop-off, cost are low badly, the lengthening cover plug of terminal block without too many space plug can be solved, and yet there are no report about this plug.
Summary of the invention
The purpose of this utility model is, provides that a kind of structure is simple, fail safe good, difficult drop-off, cost are low, can solve the lengthening cover plug of terminal block without too many space plug.
For achieving the above object, the technical scheme that this practicality is taked is:
A kind of lengthening overlaps plug, and described lengthening cover plug is provided with header body, inserted sheet, and described inserted sheet is positioned in header body, and described inserted sheet matches with the jack on terminal block, and described inserted sheet is respectively equipped with metallic conduction cover; Described metallic conduction cover is thick is 0.5 ~ 1mm; Inserted sheet surrounding outer surface is close to by described metallic conduction cover; Described metallic conduction puts and is provided with fixed strip; Described fixed strip is rectangle, and overlaps Integratively formed with metallic conduction; Described fixed strip extends respectively between two metallic conduction covers; Rubber insulation sleeve is provided with below described fixed strip; The metallic conduction that described rubber insulation sleeve is close to below fixed strip puts.
Described metallic conduction cover is consistent with the shape of inserted sheet.
Described metallic conduction cover top is equal with the height of inserted sheet to the distance of fixed strip upper surface.
Described lengthening cover plug comprises holes and lengthens cover plug and first two type of three holes lengthening inserting.
The utility model advantage is:
1, one lengthening cover plug of the present utility model, realizes two hole plugs by metallic conduction cover and three hole plugs use simultaneously, and its cost is low, easy to use, without the need to over-bought terminal block;
2, by fixed strip location determination plug position, effectively prevent from coming off in plug use procedure, ensure the reliability of plug energising;
3, by rubber insulation sleeve, avoid electric leakage, fail safe is good.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation lengthening cover plug of the present utility model.
Accompanying drawing 2 is structural representations that another kind of the present utility model lengthens cover plug.
Embodiment
Also with reference to accompanying drawing, the utility model is further described below in conjunction with embodiment.
The Reference numeral related in accompanying drawing and part as follows:
1. header body 11. inserted sheet
12. metallic conductions overlap 13. rubber insulation sleeves
14. fixed strips
embodiment 1
Please refer to Fig. 1, Fig. 1 is a kind of structural representation lengthening cover plug of the present utility model.A kind of lengthening overlaps plug, and described plug comprises header body 1; Described header body 1 is provided with inserted sheet 11; Described inserted sheet 11 matches with the jack on terminal block; Described inserted sheet 11 is respectively equipped with metallic conduction cover 12; Described metallic conduction overlap 12 thick be 0.5 ~ 1 millimeter; Inserted sheet 11 surrounding outer surface is close to by described metallic conduction cover 12; Described metallic conduction cover 12 is provided with fixed strip 14; Described fixed strip 14 is rectangle, and to overlap 12 with metallic conduction be Integratively formed; Described fixed strip 14 extends respectively between two metallic conduction covers 12; Rubber insulation sleeve 13 is provided with below described fixed strip 14; Described rubber insulation sleeve 13 is close on the metallic conduction cover 12 below fixed strip 14.
It should be noted that: the shape of described inserted sheet 11 and height are according to standard design; Described metallic conduction cover 12 is consistent with the shape of inserted sheet 11, and preferably, it is equal with the height of inserted sheet 11 to the distance of fixed strip 14 upper surface that metallic conduction overlaps 12 tops, when being convenient to metallic conduction cover 12 insertion terminal block, ensures its reliability of conducting electricity; Described metallic conduction cover 12 in a state of use time, be divided into current-carrying part and insulated part, wherein, the part of fixed strip 14 upper end is current-carrying part, and the part of fixed strip 14 lower end is insulated part; Described metallic conduction cover 12 has the electric action identical with inserted sheet 11, increases plug, save usage space, its two holes plug and three hole plugs can be inserted on same terminal block, without the need to over-bought terminal block simultaneously by metallic conduction cover 12; Described metallic conduction cover 12 has good elasticity and enough mechanical strengths, the mechanical stress that can stand the falling of plug generation in use, impact, extruding etc. is brought; Time under using state, metallic conduction cover 12 is inserted in jack, metallic conduction cover 12 conduction, and then inserted sheet 11 is conducted electricity; Described fixed strip 14 in a state of use time, with jack EDGE CONTACT, there is the effect of location, when plug is inserted in jack, whether carry out location determination plug with jack EDGE CONTACT according to fixed strip 14 and whether be plugged, avoid plug from falling simultaneously; Described rubber insulation sleeve 13 good insulation preformance, has and prevents leakage protection, and avoid when user is when inserting plug or taking out plug, finger contacts with conductive metal sheet unavoidably, and staff hits easy electric shock.
One of the present utility model lengthens cover plug using method: first conducting metal cover 12 is enclosed within inserted sheet 11, and guarantees that two metallic conduction covers 12 are highly concordant; Then on metallic conduction cover 12 cover respectively below fixed strip 14, rubber gathers edge cover 13; Finally plug is inserted in jack, when fixed strip 14 and jack EDGE CONTACT, namely ensure that plug correctly inserts in jack.
embodiment 2
Please refer to Fig. 2, Fig. 2 is the structural representation that another kind of the present utility model lengthens cover plug.The present embodiment is substantially the same manner as Example 1, and difference is, embodiment 1 is that holes lengthens cover plug, and the present embodiment is the lengthening cover plug in three holes.
One lengthening cover plug of the present utility model, realizes two hole plugs by metallic conduction cover 12 and three hole plugs use simultaneously, and its cost is low, easy to use, without the need to over-bought terminal block; By fixed strip 14 location determination plug position, effectively prevent from coming off in plug use procedure, ensure the reliability of plug energising; By rubber insulation sleeve 13, avoid electric leakage, fail safe is good.
