[detailed description of the invention]

Refer to shown in Fig. 1-3, a kind of water repellent component 100 disclosed by first embodiment. Water repellent component 100 is applied to the housing 210 of an electronic installation 200. Housing 210 has the gateway 211 of a corresponding water door 300, the inside and out of connection housing 210. Water repellent component 100, in order to close gateway 211, is invaded to housing 210 internal with the moisture or dust avoiding outside by gateway 211. Water repellent component 100 comprises water door 300, housing 210, several hinges 120 and several metal screws 140.

Refer to shown in Fig. 4-5. Water door 300 has outside plate 110 and inner panel 130. Outside plate 110 is generally rectangular slab construction. Outside plate 110 has outer surface 111 and an inner surface 112. Additionally, outside plate 110 is mainly made of plastics, inner panel 130 connects outside plate 110 and is made primarily of metal to increase intensity.

Refer to shown in Fig. 4-5. In first embodiment, water repellent component 100 comprises two hinges 120. But the quantity of hinge 120 is not limited with two. Each hinge 120 is respectively provided with two blades 121 of mutual pivot joint, and each blade 121 is made primarily of metal. In each hinge 120, two blades 121 one of them be fixed on the outer surface 111 of outside plate 110, and be positioned at the edge of outer surface 111, another blade 121 is fixed on housing 210 and a side of corresponding gateway 211. Two blades 121 in order to pivot joint outside plate 110 in housing 210, to make water door 300 connect housing 210. Therefore, water door 300 is rotatably covered in gateway 211, uses closing gateway 211. And inner surface 112 is internal towards housing 210.

Refer to shown in Fig. 2-5. The profile of inner panel 130 is substantially identical with outside plate 110, but is slightly less than outside plate 110. Inner panel 130 is incorporated into outside plate 110. In first embodiment, inner panel 130 is incorporated on the inner surface 112 of outside plate 110, and inner panel 130 does not expose to the outer surface 111 of this outside plate 110. In other application examples of the present invention, through the cladding processing procedure such as injection, inner panel 130 is embedded in outside plate 110 internal and do not expose. Wherein, inner panel 130 is made primarily of metal, and the hardness of metal material is more than the hardness of the plastic material of outside plate 110. The inner panel 130 being incorporated into outside plate 110 improves the rigidity of outside plate 110, to reduce amplitude of deformation during outside plate 110 stress.

Refer to shown in Fig. 2-5. Metal screw 140 some is arranged in the outer surface 111 of outside plate 110, and is incorporated into inner panel 130, and fixing inner panel 130 is in outside plate 110. All the other screws 140 wear each blade 121 to make blade 121 be connected to the outer surface 111 of housing 210 and outside plate 110.Wherein, blade 121, screw 140 and inner panel 130 are made by identical metal material so that it is do not have potential difference between waiting, with the problem avoiding potential difference to cause specific components corrosion rate too fast. Aforesaid metal material can be the metal that rustless steel, aluminium alloy or almag etc. are antirust and corrosion resistance is good.

As shown in Figure 2-5, water repellent component 100 more comprises a flexible waterproof case 150, made by sponge or rubber etc. Flexible waterproof case 150 is incorporated into the inner surface 112 of outside plate 110, in order to be pressed in gateway 211 to close gateway 211. In first embodiment, flexible waterproof case 150 is covered in inner panel 130 simultaneously so that inner panel 130 is between outside plate 110 and flexible waterproof case 150. Being embedded in the application examples of outside plate 110 in inner panel 130, flexible waterproof case 150 directly sticks in inner surface 112.

Refer to shown in Fig. 6. Water repellent component 100 more comprises a fastener 160, is slidably joined in the outer surface 111 of outside plate 110, and the side corresponding to outer surface 111 is arranged. Specifically, outside plate 110 has a chute 113, is formed at the outer surface 111 of outside plate 110. One end of chute 113 is open state in a lateral edges of outer surface 111. Fastener 160 moves back and forth in chute 113. Additionally, fastener 160 has more several elongated aperture slots 161, arrange parallel to each other. The bearing of trend of each elongated aperture slots 161 is parallel to the direction that fastener 160 moves back and forth in chute 113. Water repellent component 100 more comprises several fixtures 170. Each fixture 170 be each passed through elongated aperture slots 161 one of them, and in conjunction with fastener 160 in outside plate 110 so that fastener 160 is without departing from outside plate 110, and the bearing of trend being able to the elongated aperture slots 161 on edge moves back and forth.

In at least one application examples of the present invention, elongated aperture slots 161 and fixture 170 can omit. Chute 113 is a dovetail groove. Fastener 160 is incorporated in dovetail groove, and moves back and forth in dovetail groove, makes fastener 160 without departing from outside plate 110.

Consult shown in Fig. 2 and Fig. 6. Housing 210 more comprises a clasp groove 212, is positioned at a side of gateway 211. Fastener 160 has more a hook part 162, protrudes from the side of outside plate 110, and rough with outside plate 110 perpendicular, in order to be buckled in the clasp groove 212 of this housing 210. When, under the state that outside plate 110 is covered in gateway 211, the hook part 162 of fastener 160 is buckled in the clasp groove 212 of housing 210, and makes outside plate 110 be maintained at the state covering gateway 211. Meanwhile, flexible waterproof case 150 is pressed closes gateway 211 on gateway 211, embeds housing 210 with the dust or liquid completely cutting off outside further internal.

As it was previously stated, outside plate 110 is mainly made of plastics. And blade 121, screw 140 are all contact with the outside plate 110 with plastic material with inner panel 130. The plastic material of outside plate 110 and the metal material of blade 121 reduce the potential difference between outside plate 110 and blade 121. The plastic material of outside plate 110 and the metal material of screw 140 reduce the potential difference between this outside plate 110 and screw 140. Owing to above-mentioned potential difference is lowered, therefore the metal material of blade 121, screw 140 is in wet environment, and corrosion rate can be greatly reduced, thus promoting the useful life of water repellent component 100. Although outside plate 110 comprises plastic material, but owing to inner panel 130 improves the rigidity of outside plate 110, therefore outside plate 110 can maintain low deflection, positively to oppress flexible waterproof case 150, and closes gateway 211.

Refer to shown in Fig. 7, a kind of water repellent component 100 disclosed by second embodiment of the invention. The present embodiment is roughly the same with previous embodiment, therefore illustrates only for difference place below.

Water repellent component 100 more comprises positioning piece 180, is movably arranged at outer surface 111 and is arranged in chute 113. The fastener 160 of the second embodiment more comprises a locating slot 163. When keeper 180 is buckled under the state of clasp groove 212 of housing 210 in fastener 160, keeper 180 is embedded in locating slot 163. It is orthogonal that keeper 180 is embedded in the direction that moves back and forth of the moving direction in locating slot 163 and fastener 160, makes fastener 160 will not move relative to outside plate 110.

Such as first embodiment, the outside plate 110 of the present invention is made with plastic material, and its corrosion resistance is high. Inner panel 130 is incorporated into outside plate 110 and can promote the rigidity of outside plate 110, to maintain the outside plate 110 sealing effectiveness to gateway 211. Additionally, reduce the potential difference between outside plate 110 and blade 121 by the plastic material of outside plate 110 and the metal material of blade 121, and the metal material of the plastic material of outside plate 110 and screw 140 reduces the potential difference between outside plate 110 and screw 140. Above-mentioned potential difference is lowered, therefore the metal material of blade 121, screw 140 is in wet environment, and corrosion rate can be greatly reduced, thus promoting the useful life of water repellent component 100.
