Abstract
The invention relates to a novel male and female plug used for a dust collector. The bottom part of the plug pin of a male plug is provided with a fastening sealing structure. The fastening sealing structure comprises a sealing convex stand, and a fastening sealing ring and a fastening sealing protrusion which are formed by rubber elastomers. The opening of a female plug is provided with a sealing pit which comprises a first sealing pit and a second sealing pit from outside to inside. The cross section of the first sealing pit has an inverted trapezoid structure and the shape and size of the first sealing pit are matched with those of the sealing convex stand which is sleeved by a plug sealing ring. The shape and size of the second sealing pit are matched with those of the sealing protrusion. The plug pin of the male plug is plugged into the opening of the female plug so as to be closely connected with the opening of the female plug. Problems that the plugging part of the male and female plug is liable to loose and line short circuit and even electric leakage situations are liable to occur are solved so that safety hidden trouble is avoided.
Description
Technical field
The present invention relates to a kind of novel male and female to insert, particularly a kind of novel dust collector male and female is inserted, and belongs to the electric power connection line field of electric equipment.
Background technology
Current dust catcher generally uses straight shape electric power connection line, when electric floor brush of dust collector long-term work, straight shape electric power connection line can not stand the bending of high frequency time, easily causes the breakage of line body and connector to loosen.
Current electric power connection line is plugged together by male and female usually, the structure that current male and female is inserted comprises male plug body, female plug body, male plug body one end is provided with public housing, slotting spring is provided with in public housing, female plug body one end is provided with the parent shell of opening, when public housing inserts parent shell, public housing and parent shell just securely link together, and contact pin can insert in slotting spring.Particular job environment of dust catcher makes there is requirement to the length of power line, because power line length is inadequate, often need to use male and female to inject row and plug together connection, but when electric floor brush of dust collector long-term work, the splicing position inserted due to male and female easily produces loosening, very easily there is line short, even leak electricity, for electric safe handling hides some dangers for.
Summary of the invention
Technical problem to be solved by this invention provides a kind of novel dust collector male and female to insert for above drawback, and the splicing position solving male and female slotting easily produces loosening, very easily line short occurs, and the situation of even leaking electricity occurs, and avoids potential safety hazard.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of novel dust collector male and female is inserted, comprise the connecting line main body of spring wire structure, described connecting line main body two ends are respectively equipped with male plug and female plug, described male plug is provided with contact pin, female plug one end is provided with opening, wherein, fastening seal structure is provided with bottom described male plug contact pin, described fastening seal structure comprises seal boss, the fit sealing ring be made up of rubber elastomer and fit sealing projection, described seal boss is positioned at bottom male plug contact pin, in circular platform type structure, is integral type structure with described male plug body; It is outside that described fit sealing ring set is combined in described seal boss, is split-type structural with seal boss, described fit sealing ring cross section structure triangular in shape; Described fit sealing projection is positioned at seal boss side, is cirque structure, is linked in contact pin surrounding, and described fit sealing is protruding is integral type structure with described seal boss; Described female plug opening part is provided with sealing depression, and described depression, from comprising the first sealing depression outside to inside, seal cave in second, and described first to seal concave cross-section be inverted trapezoidal structure, and its shape size matches with the seal boss being sheathed with grafting sealing ring; The shape size of described second sealing depression matches with described seal convexity; Described male plug contact pin inserts in female plug opening, with female plug opening compact siro spinning technology.
Beneficial effect of the present invention is: plug unique fastening seal structure by male and female, adopt hermetically-sealed construction and sealing cave in the use of, effectively can improve the fastening effect that male and female inserts joint.Unique fit sealing ring adopts del structure, during with female plug grafting, can be effectively fastening, and difficult drop-off loosens, and is made up of rubber elastomer, effectively can completely cut off electrically, reduce the possibility electrically leaked outside.Use seal convexity and second seals to cave in and coordinates, and male and female can be made to insert connection and more fit.
The present invention is rational in infrastructure, and when solving electric floor brush of dust collector long-term work, the splicing position inserted due to male and female easily produces loosening, and very easily line short occurs, even the generation of drain conditions, improves coefficient of safety greatly, improves result of use.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of novel dust collector male and female is inserted, comprise the connecting line main body 1 of spring wire structure, described connecting line main body 1 two ends are respectively equipped with male plug 2 and female plug 3, described male plug 2 is provided with contact pin 21, female plug 3 one end is provided with opening 31, wherein, fastening seal structure 4 is provided with bottom described male plug contact pin 31, described fastening seal structure 4 comprises seal boss 41, the fit sealing ring 42 be made up of rubber elastomer and fit sealing projection 43, and described seal boss 41 is positioned at bottom male plug contact pin 31, in circular platform type structure, be integral type structure with described male plug body 2; It is outside that described fit sealing ring set 42 is combined in described seal boss 41, is split-type structural with seal boss 41, described fit sealing ring 42 cross section structure triangular in shape; Described fit sealing projection 43 is positioned at seal boss 41 side, is cirque structure, is linked in contact pin 31 surrounding, and described fit sealing protruding 43 is integral type structure with described seal boss 41; Described female plug opening 31 place is provided with sealing depression 5, described depression 5 is from comprising the first sealing depression 51 outside to inside, seal depression 52 with second, described first sealing depression 51 cross section is inverted trapezoidal structure, and its shape size matches with the seal boss 41 being sheathed with grafting sealing ring 42; The shape size of described second sealing depression 52 matches with described seal convexity 43; Described male plug contact pin 21 inserts in female plug opening 31, with female plug opening 31 compact siro spinning technology.
Beneficial effect of the present invention is: plug unique fastening seal structure by male and female, adopt hermetically-sealed construction and sealing cave in the use of, effectively can improve the fastening effect that male and female inserts joint.Unique fit sealing ring adopts del structure, during with female plug grafting, can be effectively fastening, and difficult drop-off loosens, and is made up of rubber elastomer, effectively can completely cut off electrically, reduce the possibility electrically leaked outside.Use seal convexity and second seals to cave in and coordinates, and male and female can be made to insert connection and more fit.
