Description
Technical field
The utility model relates to mains charger technical field, refers in particular to a kind of mains charger waterproof construction.
Background technology
In prior art, mains charger generally includes lid, circuit board, plug and charging wire, forms containing cavity in lid, circuit board is arranged in containing cavity, and plug one end is electrically connected with city, and the other end is connected with circuit board, charging wire one end is connected with circuit board, other end reception charging electrical equipment.
As shown in Figures 1 and 2, the mains charger waterproof construction that prior art discloses, upper cover body 10 arranges push/pull slot 101, inserts screw 20 in push/pull slot 101, insert in lower cover 30 through upper cover body 10, upper cover body 10 is fixedly mounted on lower cover 30 by screw 20; Push/pull slot 101 sidewall arranges jump ring 102, and the inserting column 401 of transparent surface cover 40 inserts in this push/pull slot 101, and arranges draw-in groove 402 on inserting column 401.
Under charging using state, cover 40 inserting column 401 inserts bottom push/pull slot 101, and cover 40 and upper cover body 10 are fitted; Under non-charging using state, pull up cover 40 inserting column 401, jump ring 102 snaps in draw-in groove 402, and restriction inserting column 401 pulls up further, and charging wire is wrapped on inserting column 401, and facilitate charging wire to receive under non-working condition, its defect is:
Push/pull slot sidewall arranges jump ring, owing to there is larger gap between jump ring and push/pull slot sidewall, makes aqueous vapor easily enter open circuit potential plate in lid, and then damage circuit board and affect useful life of mains charger.
Utility model content
The purpose of this utility model is to provide a kind of mains charger waterproof construction, to stop aqueous vapor to enter mains charger lid internal corrosion circuit board, increases the service life.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of mains charger waterproof construction, comprises lid, circuit board, plug, charging wire and cover; Circuit board is arranged in lid, and plug is connected with circuit board input, and charging wire is connected with circuit board output; Lid forms push/pull slot, and spring spool is arranged in push/pull slot, and cover arranges inserting column, and inserting column is slidably socketed on spring spool.
Further, spring spool top arranges the grab of restriction inserting column stroke, and the axial draw-in groove of corresponding formation on inserting column, grab snaps in draw-in groove.
Further, arrange through hole in spring spool, spring spool is locked in lid through through hole by screw.
Further, lid is made up of upper cover body and lower cover, and upper cover body covers on lower cover, and spring spool is locked in upper cover body through through hole by screw, and by upper cover body and lower cover sealed.
After adopting such scheme, the utility model lid forms push/pull slot, spring spool is arranged in push/pull slot, and cover arranges inserting column, and inserting column is slidably socketed on spring spool, when charger charging uses, cover inserting column inserts bottom push/pull slot, and cover and upper cover body are fitted, when the non-charging of charger uses, pull up cover inserting column, charging wire is wrapped on inserting column.The utility model is when push-and-pull cover, the sealing of lid can not be affected, and without the need to arranging jump ring at push/pull slot, be unlikely to form gap at sidewall, affect sealing, make the utility model waterproof effect better, effectively stop aqueous vapor to enter mains charger lid internal corrosion circuit board, increase the service life.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 3 to Fig. 5, a kind of mains charger waterproof construction that the utility model discloses, comprise lid 1, circuit board 2, plug 3, charging wire (not shown), spring spool 4 and cover 5.
Circuit board 2 is arranged in lid 1, and usually, lid 1 is made up of upper cover body 11 and lower cover 12, and upper cover body 11 covers on lower cover 12.
Plug 3 is connected with circuit board 2 input, and charging wire is connected with circuit board 2 output, and circuit board 2 is mainly used in civil power to be converted to the voltage being suitable for electrical equipment charging.
Upper cover body 11 is formed push/pull slot 111, spring spool 4 is arranged in push/pull slot 111, cover 5 is arranged inserting column 51, and inserting column 51 is slidably socketed on spring spool 4.
In the present embodiment, spring spool 4 top arranges the grab 41 of restriction inserting column 51 stroke, and the axial draw-in groove 511 of corresponding formation on inserting column 51, grab 41 snaps in draw-in groove 511.
For making spring spool 4 easy for installation, arrange through hole in spring spool 4, spring spool 4 is locked in upper cover body 11 through through hole by screw 6, and by sealed to upper cover body 11 and lower cover 12.
When the charging of the utility model charger uses, cover 5 inserting column 51 inserts bottom push/pull slot 111, and cover 5 and upper cover body 11 are fitted, and when the non-charging of charger uses, pull up cover 5 inserting column 51, charging wire is wrapped on inserting column 51.When push-and-pull cover 5, the sealing of lid 1 can not be affected, make waterproof effect better, effectively stop aqueous vapor to enter mains charger lid 1 internal corrosion circuit board, increase the service life.
The foregoing is only preferred embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection range of this case.
