Abstract
The utility model discloses a waterproof USB security protection structure. A USB is connected with a circuit board through a wire. The circuit board is installed in a shell. The USB is coated with a plastic outer layer, and the wire connecting the circuit board and the USB is integrally formed in the plastic outer shell. A mounting groove is formed in the plastic outer layer, soft plastic is arranged in the mounting groove, and the shell is clamped into the mounting groove of the plastic outer layer. The waterproof USB security protection structure of the utility model can effectively prevent corrosion of water vapor to the circuit board and improve the service life of the circuit board.
Description
Technical field
The utility model relates to a kind of USB waterproof safety safeguard structure.
Background technology
In prior art, many electrical appliances all can be used USB interface, and as charger for mobile phone and USB torch etc., described USB is connected with circuit board, and circuit board is arranged in housing conventionally, and the input of this circuit board is connected with the plug of grafting civil power.
Yet the USB of prior art is directly connected with circuit board, or be connected with circuit board by wire.Therefore, steam can be creeped and enter into circuit board from USB outside, and then open circuit potential plate, makes circuit board too much cause short circuit because of steam; Meanwhile, after USB is arranged in housing, have larger gap between housing and USB, steam easily enters and open circuit potential plate by this gap.
In view of the described defect of prior art USB structure, the present invention furthers investigate, and develops a kind of USB waterproof safety safeguard structure that overcomes described defect, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of USB waterproof safety safeguard structure, to block the corrosion of steam to circuit board, improves circuit board useful life.
For reaching above-mentioned purpose, solution of the present utility model is:
A USB waterproof safety safeguard structure, USB is connected with circuit board by wire, and circuit board is arranged in housing, at USB skin, plastic cement skin is set, and the wire of connecting circuit board and USB is shaped in plastic cement skin; On plastic cement skin, form mounting groove, soft plastic is set in mounting groove, housing is connected in the outer mounting groove of plastic cement.
Further, shown in plastic cement skin be " U " type, a side opening wherein, USB is arranged in " U " shape glue skin.
Further, form grab on USB, accordingly, on plastic cement skin, form draw-in groove, grab embeds in draw-in groove USB is arranged in plastic cement skin.
Adopt after such scheme, the utility model arranges plastic cement skin at USB skin, and the wire of connecting circuit board and USB is shaped in plastic cement skin, makes steam to creep and to enter into circuit board from USB outside along wire, and then corrode this circuit board, form one-level waterproof safety safeguard structure; Simultaneously, on plastic cement skin, form mounting groove, soft plastic is set in mounting groove, housing is connected in the outer mounting groove of plastic cement, gap between plastic cement skin and housing is by soft plastic shutoff, steam cannot be entered and open circuit potential plate by the gap between plastic cement skin and housing, form secondary waterproof safety safeguard structure.Therefore, the utility model can effectively protect steam and enter, and the corrosion of blocking-up steam to circuit board improves circuit board useful life.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 4, a kind of USB waterproof safety safeguard structure that the utility model discloses, in the present embodiment, is applied in charger.As shown in Figure 3, USB1 is connected with circuit board 2 by wire 11, and circuit board 2 is arranged in housing 3, and this housing 3 is comprised of upper casing 31 and lower casing 32.
At USB1 skin, plastic cement skin 4 is set, the wire of connecting circuit board 2 and USB1 is shaped in plastic cement skin 4, make steam along wire 11, to creep and to enter into circuit board 2 from USB1 outside, and then corrode this circuit board 2, form one-level waterproof safety safeguard structure.On plastic cement skin 4, form mounting groove 41, soft plastic 5 is set in mounting groove 41, housing 3 is connected in outer 4 mounting grooves 41 of plastic cement, and steam cannot be entered and open circuit potential plate 2 by the gap between plastic cement outer 4 and housing 3, forms secondary waterproof safety safeguard structure.
In the present embodiment, shown in plastic cement skin 4 be " U " type, a side opening wherein, USB1 is arranged in " U " shape glue skin 4, this plastic cement skin 4 is comparatively simple, and USB1 is easy for installation.
When USB1 installs, form grab 12 on USB1, as shown in Figure 1, accordingly, form draw-in groove 41 on plastic cement skin 4, grab 12 embeds in draw-in groove 41 USB1 is arranged in plastic cement skin 4, as shown in Figure 4.
The utility model forms two-stage waterproof safety safeguard structure, effectively protects steam and enters, and the corrosion of blocking-up steam to circuit board 2, improves 2 useful lifes of circuit board.
The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection range of this case.
