Detailed description of the invention
In order to more clearly state this utility model, below in conjunction with the accompanying drawings this utility model is further described.
Refering to Fig. 1-3, this utility model protective cover on wiring board, including the first protective cover the 1, second protective cover 2 and the 3rd protective cover 3, wiring board 4 is provided with the first adapter the 41, second adapter 42 and screw hole 43；First adapter 41 and the second adapter 42 be respectively arranged with the first corresponding protection board 44 and the second protection board 45 on the position that wiring board 4 contacts, and run through and around the screw hole 43 of wiring board 4, be surrounded with the 3rd protection board 46；After first protective cover 1 is set on the first adapter 41, the first protective cover 1 and the first protection board 44 enclose the first annular seal space sealing the first adapter 41；After second protective cover 2 is set on the second adapter 42, the second protective cover 2 and the second protection board 45 enclose the second annular seal space sealing the second adapter 42；After one end of 3rd protective cover 3 is suitable with screw hole 43, and screw hole 43 is inserted in one end of the 3rd protective cover 3, screw hole 43 sealing paste is combined in therebetween by the other end and the 3rd protection board 46 of the 3rd protective cover 3.
nullCompared with prior art，Protective cover on wiring board of the present utility model，During use，The most sheathed first protective cover 1、After second protective cover 2 and the 3rd protective cover 3，The first annular seal space sealing the first adapter 41 is enclosed by the first protective cover 1 and the first protection board 44，Second protective cover 2 and the second protection board 45 enclose the second annular seal space sealing the second adapter 42，And the 3rd one end of protective cover 3 insert after screw hole 43，Screw hole 43 sealing paste is combined in therebetween by the other end and the 3rd protection board 46 of the 3rd protective cover 3，Realize the first adapter 41 on wiring board 4、Fully sealing of second adapter 42 and screw hole 43，During spraying three-proofing coating，Three-proofing coating is avoided to pollute the first adapter 41、Second adapter 42 and screw hole 43 etc.，And avoid screw hole 43 to insulate and the imperfect earth that causes.After coating material has solidified, manually take off a protective cover, the second protective cover 2 and the 3rd protective cover 3, and sorting placement, wait that next time uses.Protective cover on wiring board of the present utility model can be reused, and is greatly saved gummed paper cost.And; owing to the first adapter 41 and the second adapter 42 are protected by the first protective cover 1 and the second protective cover 2 the most respectively, so when using selective spray equipment, spray procedure becomes the simplest; need not deliberately dodge these positions forbidding coating, thus improve spray efficiency on the whole.
In the present embodiment; first adapter 41 is multiple and the first connecting pin of column distribution; and first protective cover 1 be arranged to wrap the rectangular structure of multiple first connecting pin simultaneously; first end face of rectangular structure is provided with the first opening 11; after first protective cover 1 is set on multiple connecting pin by the first opening 11 set, it is the first annular seal space that five end faces of remaining of rectangular structure and the first protection board 44 enclose.First protective cover 1 of rectangular structure is used for the adapter that shape is relatively regular.
In the present embodiment; second adapter 42 is two the second connecting pins of the same size; second protective cover 2 is two columnar structures that can wrap the second connecting pin respectively, and each columnar structures is equipped with the second opening 21, and the second opening 21 is suitable with the diameter of the second connecting pin.Second protective cover 2 of columnar structures is mainly for the protection of binding post and the adapter of contact pin class.Certainly, the number of the second connecting pin in this case is not limited to two, and the structure of the second protective cover 2 is not limited to column type, the protective cover made according to different numbers or structure, is simple deformation and the conversion of this case, falls in the range of this case protection.
In the present embodiment, the two ends shape of the 3rd protective cover 3 is cylindric or coniform, and one end diameter of the 3rd protective cover 3 is less than the diameter of the other end.Owing to screw hole 43 is circular, the most only needing one end of the 3rd protective cover 3 to run through screw hole 43, the other end directly overlays on the 3rd protection board 46, so that it may sealed up by screw hole 43.Certainly, in this case, the two ends shape of the 3rd protective cover 3 is not limited to, such as the screw hole less for diameter, use coniform more preferably, it is simple to operation.
In the present embodiment, the material of first protective cover the 1, second protective cover 2 and the 3rd protective cover 3 is the one in silica gel material, polyurethane material, metal material, bakelite or organic synthesis macromolecular material.Certainly, this case is not limited to above material, it is also possible to be the material of other repeatable utilizations.
Advantage of the present utility model is:
1) save labour cost, save more than 50% cost of labor than traditional rubberizing paper；
2) efficiency more than 50% is improved than the protection of traditional rubberizing paper；
3) due to gummed paper not reproducible use, protective cover can be reused, and is greatly saved gummed paper cost；
4) protected by the first protective cover 1 and the second protective cover 2 the most respectively due to the first adapter 41 and the second adapter 42; so when using selective spray equipment; spray procedure becomes the simplest; need not deliberately dodge these positions forbidding coating; thus improve spray efficiency on the whole, because the spray procedure of complexity is certain to reduce production efficiency.
Only several specific embodiments of the present utility model disclosed above, but this utility model is not limited to this, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
