In addition, as shown in Figure 5, the clearance G 2 of extending along the direction (in the present embodiment normally horizontal direction) that deviates from wall W is formed between the top wall portion 5b of the top wall portion 11a of inwall 11 and lid 5, and the dependent wall 11b of portion stretches out from top wall portion 11a along the direction that deviates from wall W simultaneously.Can allow like this to remove water along the direction that deviates from wall W.Can suitably select the size of clearance G 2 according to the water repellency of top wall portion 5b, top wall portion 11a and the 11b of dependent wall portion, the water yield that penetrates into inwall 11 and other factors.In addition, fine recesses of advancing on the bearing of trend of inwall 11 or spine can be arranged on the upper surface of top wall portion 11a and the 11b of dependent wall portion or the lower surface of top wall portion 5b, thereby help along the direction draining of clearance G 2 extensions.

In this, according to present embodiment, the 11b of dependent wall portion extends in one way, and promptly its leading section terminates in the boundary vicinity between the top wall portion 5e of the top wall portion 5b of lid 5 and outward extending protuberance 17.The water of discharging from clearance G 2 is flowed down along the inner surface (inner surface of top wall portion 5e) of lid 5, thereby can prevent that sealing is splashed on the block 2.Further, flow down along the inner surface of top wall portion 5e, can obtain drainage line with simple structure by making water.

In addition, in the present embodiment, the top wall portion 11a of inwall 11 is formed asymmetrically on left and right directions.Fig. 7 shows the top wall portion 11a under vertical condition of amplifying.As what seen from Fig. 7, the convex surface summit M1 of top wall portion 11a has been moved to the left apart from δ from the intersection center M (base 6) of waterproof cover 1.

If water penetrates into top wall portion 11a, just may occur in the situation that on top wall portion 11a, forms water droplet under the capillary effect.According to the left and right sides dissymmetrical structure of present embodiment, the upper surface of top wall portion 11a zone about it has different gradients, and the left and right sides balance of this expression water droplet on top wall portion 11a can be destroyed because of action of gravity.This has just reduced water under the capillary effect and rest on tendency on the top wall portion 11a, and anti-thus sealing is splashed on the block 2 from the block top.

Further, in the present embodiment, provide leak paths in the present invention so that promote water is penetrated on the top wall portion 11a from waterproof cover 1 outside, thereby make the water yield that penetrates on the top wall portion 11a asymmetric on left and right directions.

Especially, in a position that moves right from the intersection center of top wall portion 5b when the front is watched, form an otch 5h (Fig. 8) as leak paths, it is communicated with gap between the protuberance 6b of notch 5c (top wall portion 5b) and linkwork 16, and further with the internal communication of waterproof cover 1.As shown in Figure 7, the otch 5h that forms in order to strengthen infiltration can guarantee that the water yield of infiltrating on the right side is bigger than the left side.Can guarantee that like this left and right sides balance of water droplet on top wall portion 11a destroy because of the different water infiltration capacities of left and right sides, reduced water thus under the capillary effect and rest on tendency on the top wall portion 11a, and anti-sealing is splashed on the block 2 from the block top.

Further, in this layout, preferably in the position of having infiltrated big water gaging, the inclined surface that continues to tilt at wider portion upper edge assigned direction should be formed on the top wall portion 11a, thereby helps the draining of gravity and suppress water droplet in reliable more mode.

In addition, in the present embodiment, otch 5h only is formed on the inner surface of lid 5, thereby from can't see otch 5h in appearance, is exactly this situation among Fig. 6.5h expands under the situation of the outer surface that contacts lid at the hypothesis otch, will be formed in proportion to the exposure size in the gap that is enlarged such as the shortcoming of introducing dust, obstruction or the like.But in the present embodiment,, can avoid this situation by on the inner surface of lid 5, forming otch 5h.

Simultaneously, according to present embodiment, be used for seal 8 that anti-sealing infiltrates and be connected, as previously described with dimple 5i on the bottom that is formed on lid 5.Seal 8 comprises the frame section 8a that is embedded among the dimple 5i and has cross otch 8c and be arranged in the folding part 8b of frame section 8a inside.Folding part 8b can as one man be out of shape with the exterior contour of the electric wire 3 that runs through folding part 8b, thereby has strengthened sealing.

Further, as shown in Figure 9, plate rib 15 is arranged on the upside position adjacent place (being the inboard of lid 5) with seal 8, and described seal is connected on the bottom of lid 5, suppresses seal 8 thus and bends to (inner space of waterproof cover 1) in the lid 5.Therefore, can prevent that sealing enters from the outside by the aduncate seal of other modes.Entering of water can also itself be limited by rib 15.Further, rib 15 has otch 15a, is used to allow electric wire 3 to pass therethrough.Otch 15a has limited the direction that electric wire 3 extends, and prevents that thus electric wire 3 from crossing bending greatly in the adjacent part of itself and seal 8, and so widen grooving 8c, this will reduce sealing.

Further,, as shown in Figures 9 and 10, provide matching mechanism, be used to make lid 5 and base 6 to be fitted to each other in the place of contiguous dimple 5i according to present embodiment.More specifically,

Further, according to present embodiment, as shown in figure 10, abducent protuberance 17 is formed on the intersection center of lid 5, and this protuberance 17 is from the protruding predetermined width of outside wall portions 5a, and extends in vertical direction.Abducent protuberance 17 is generally the U-shaped cross section, and it is limited with the side wall portion 5f that is arranged on the side of top wall portion 5e by the top wall portion 5e with strips vertical extent preset width (1/3rd width of lid 5).Top wall portion 5e raises gradually from the apical margin of outside wall portions 5a.The height of abducent protuberance 17 increases on the scope from the top to the center gradually with parabolical form in a downward direction, and is remaining unchanged substantially on the scope of portion on earth from the center.In addition, comprise that tiny projection and depression (for example for shape of stripes or point-like) anti-skidding 12 is arranged on the surface of each side wall portion 5f.

This structure can be guaranteed easily to open lid 5 by catching with spurring abducent protuberance 17 in the upward direction.Further, owing to provide anti-skidding 12, so lid 5 can be caught in more reliable mode.

In addition, because the top of the top wall portion 5e of abducent protuberance 17 is near wall W, as shown in Figure 5, therefore be easy to the 11b of dependent wall portion with inwall 11 arrange on the top of top wall portion 5e near the top of top wall portion 5e, thereby the inner surface that can use top wall portion 5e is as drainage line.Further, little by little extend to away from block 2 from its top relative wall W by top wall portion 5e is designed to, water is flowed downward with the inner surface of more reliable mode along top wall portion 5e, and can prevent that sealing is splashed on the block 2.

According to aforesaid embodiment; by forming the clearance G 1 and the G2 of suitable dimension; be used between inwall 11 and other members except that inwall 11 (for example top wall portion 5b), producing capillarity; can remove water along the direction of regulation, thereby can not intake with simple structural defence block 2.

In addition, according to present embodiment, penetrate into water on the inwall 11 (top wall portion 11a) and can be dividually discharge along wall W and the direction that deviates from wall W in block 2 upper edges, thereby can prevent more reliably that sealing is splashed on the block 2 from the block top at horizontal direction.

Further, according to present embodiment, the left and right sides is unbalance to be destroyed water droplet owing to the water yield on the infiltration inwall 11 (top wall portion 11a) forms in the left and right sides balance meeting on the top wall portion 11a.This has just reduced water under the capillary effect and rest on tendency on the top wall portion 11a, and anti-thus sealing is splashed on the block 2 from the block top.

Further, according to present embodiment, the left and right sides balance of water droplet on top wall portion 11a can since the shape formation of block 2 upper inner wall 11 (top wall portion 11a) left and right sides is unbalance destroys.This has just reduced water under the capillary effect and rest on tendency on the top wall portion 11a, and anti-thus sealing is splashed on the block 2 from the block top.

Further, according to present embodiment, rib 15 can suppress the inside bending of seal 8, and the gap that provides between seal 8 and electric wire 3 thus is provided, thereby anti-sealing infiltrates in the waterproof cover 1 by the gap that other modes form.

Further, according to present embodiment, place at contiguous dimple 5i provides matching mechanism, be used to make lid 5 and base 6 to be fitted to each other, make dimple 5i and seal 8 not yielding more, infiltrate in the inner space by the gap that other modes form between seal 8 and electric wire 3 thereby limited water.

Further, according to present embodiment, use abducent protuberance 17 can easily catch lid 5 as handle, its advantage that has is easily to open and close lid 5.In addition, be the form of a groove owing to be generally the inboard of U-shaped cross section and abducent protuberance 17, described groove is suitable for downward draining, therefore can be with mode draining more reliably.Also expectation is that the width of abducent protuberance 17 is the sizes that are suitable for catching easily.

Further, according to present embodiment, on abducent protuberance 17, provide anti-skidding 12 and can make the user firmly grasp lid 5 reliably.Especially, if having the lid 5 of abducent protuberance 17 is made of transparent material, the advantage that then has is, see through anti-skidding 12 the observability that on the side wall portion 5f of abducent protuberance 17, forms even reduced, also can also see through the connection status that top wall portion 5e sees inner member significantly, thereby not hinder aspect the overall observability.

Although the preferred embodiments of the present invention described above, the invention is not restricted to the embodiments described, but comprised various modifications.

For example, different as the previous embodiment that block provides with the lead-out wire socket device that wherein is used for the power supply supply, the present invention replacedly can be applied to connect the block of switch or other electric wires.

Further, waterproof cover can be modified as many different shapes.For example, lid can be an opening in a lateral direction, rather than as in the previous examples like that in the vertical direction perforate, the introducing position of electric wire (position of dimple 5i) can relocate in the zone except that bottom centre.

Further, the previous embodiment that is formed on the block top with the gap that wherein utilizes capillarity to remove water is different, and similar gap can further be arranged in the side or the bottom surface of block or miscellaneous part.

Further, leak paths for example can form by partly enlarging the gap that exists in the linkwork.

Further, as in the base 6A shown in Figure 11 A and the 11b, upwardly extending end wall 11d can be formed at the remote edge of top wall portion 11a, and described remote edge limits the below that water flows to top wall portion 11a on the remote edge thus away from wall W.This structure can also be improved water proofing property in simple relatively mode, and like such as seal need not be provided.
