Or more desirably, the aforementioned waterproof space is slightly triangular. [Embodiment] [Best Mode for Carrying Out the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The plurality of body blocks are arranged in the above-mentioned connection box, and the connection box 6 is pressed against the wire clamp of the waterproof holder. The first one is a partial break of the moisture-proof connection box according to one embodiment of the present invention. Front perspective view of the face. In the detailed description and the patent scope, unless otherwise specified, the front side of the working surface is shown in the first drawing as the paper surface direction, the back side is the same as the drawing surface, and the upper side and the lower side are the same as the upper and lower sides of the drawing. The sides or left and right sides are in the same direction as the left and right. As shown in Fig. 1, the moisture-proof cable connecting box includes: a connecting box main body 1 whose side is opened; and a lid body 2 that can open and close to cover the front side of the connecting box 1. The connection box body 1 is, for example, an L-shaped suspension member (not shown) attached to the back surface of the box body 1, for example, an overhead cable suspension wire or the like. The lid body 2 is attached to the lower portion of the joint body 1 to be opened and closed in the up and down direction as indicated by an arrow A in the figure. The cover includes a cover surface portion 2a facing the front surface side of the connection box main body 1. The cover surface portion 2a is formed on the outer circumference, and covers the peripheral wall portion of the side portion, the upper edge portion, and the lower edge portion of the connection box main body 1. 2b. Fig. 2 is a perspective view showing the configuration of the connection box of the moisture-proof cable connecting box. As shown in Fig. 2, in addition to the vicinity of the edge on the front side of the opening of the connection box body 1, a reinforcing rib 1a projecting from the outer peripheral surface is formed, and the box body 1 is attached to the side portions. In the state of the wire, the direction of the force (that is, the lower side) has a pair of cable-introducing portions 1 b or more of optical fiber cables (hereinafter sometimes referred to as "cables") 201 through the cable introduction portion 1 b, and the first body 2 and the circumference of the two bodies are connected from the outside of the connection box body 1 by the cable application side or the back side to the front-Jr-Η® body. Also on the heavy j -- , sub-introduction -6- 200839339 (4) to the inside. The optical fiber cable 20 1 introduced into the connection box body 1 is housed in the connection box body 1 to form a connection or a branch to the other cables 20 1 . Further, a plurality of plastic optical fiber storage cases 3a (hereinafter referred to as storage boxes) are laminated on the bottom of the main body. Each of the storage cases has a hollow thin plate shape, and the upper cover can be opened and closed to form a wiring operation for taking out an optical fiber from the storage case or completing fiber arrangement in the storage case. The ends of the storage boxes are hinge-joined, and each of the storage boxes can be individually rotated up and down. Further, in order to facilitate the work, each of the storage boxes is stacked such that it gradually shifts upward and downward (Fig. 1). The lowermost storage box is a storage separator, and a single-core optical fiber that is divided into a plurality of pieces from the separator is collected into each storage box of the upper layer. The method of connecting the fiber-optic cable imported from the outside to the fiber-optic cable in the receiving box of the object to be connected is as follows. First, after all the storage boxes on the upper side of the storage box as the object are rotated and fallen down, the cover is opened and the target optical fiber cable is taken out. Further, the accommodated optical fiber cable and other optical fiber cables introduced from the outside are connected by welding, contact connection, or the like. Then, re-invest in the storage box and open the lid to complete the tapping operation. In the moisture-proof cable connection box, when the lid body 2 is closed against the connection box body 1, as shown in Fig. 1, the lid body 2 and the connection box body 1 are in the vicinity of the respective cable introduction portions 1b. In cooperation, the waterproof space 4 is separated from the inner side of the connection box body i. These waterproof spaces 4 are configured to block water droplets that are transmitted from the respective cable introduction portions 1b to the cables introduced into the connection box 200839339 (5), and the water droplets are blocked in the respective waterproof spaces 4. The shape of the waterproof spaces 4 is preferably slightly triangular in view of space efficiency. The "combination" referred to in the above includes: the front end of the partition wall 6 of the lid body 2 which can be divided when the lid body 2 is closed, and the front end of the cable holding plate 5 of the lid body 2 is abutted. Meaning, or meaning equal to the above. Fig. 3 is a front perspective view showing a state in which the lid body of the moisture-proof cable connecting case is opened. Fig. 4 is a perspective view showing a state in which the lid body of the moisture-proof cable connecting case is opened. The waterproof space 4 is shown in FIGS. 1 to 4 by: a gravity direction (lower) portion of both side portions of the cable introduction portion 1 b of the connection box body 1; and the connection box body 1 a cable retaining plate 5 formed from a side portion of the connecting box body 1 to a lower edge portion; and a side portion 1 c of the lower edge portion of the connecting box body 1; and a cover body 2 corresponding thereto a portion in the direction of gravity (lower side) of the both sides; and a partition wall 6 formed in the cover 2 from the side of the cover 2 to the lower edge; and the both sides of the lower edge of the cover 2 Composition. One or more recesses 7 through which the cable 20 1 passes are formed in the cable holding plate 5. Here, the optical fiber cable to be connected to the work is, for example, a drop cable for a small section of each user or each business place. The cross-sectional cable has a substantially cross-sectional shape and has a configuration in which an optical fiber cable is formed between the two tension members. In order to accommodate the optical fiber cable having such a cross-sectional shape, the cross-sectional shape ' formed in the concave portion 7 of the -8 - 200839339 (6) plate 5 is also formed in an angular shape along the cross-sectional shape. Fig. 5 is an enlarged perspective view showing the waterproof space of the connection box body. In the moisture-proof cable connection box, each cable 20 1 is introduced into the connection from each cable introduction portion 1 b through each of the waterproof space 4 and the recess 7 of the cable holding plate 5 as shown in Fig. 5 . Inside the box body 1. Fig. 6 is an enlarged perspective view showing the vicinity of the cable holding piece of the connection box main body. In the cable introduction portion 1b, as shown in Figs. 5 and 6, a cable holding portion formed by a plurality of cable holding pieces 8 for holding one or more cables 20 1 is formed. 9. Between the two cable holding pieces 8 adjacent to each other, it is a cable holding portion 9. That is, the cable holding piece 8 is a partition plate, and the cable 207 is held by the two cable holding pieces 8, and is supported to pass through the cable holding portion 9. The cable holding portion 9 is formed to have a width slightly equal to the thickness of the cable 20 1 . Further, each of the cable holding pieces 8 and 8 has a slightly curved shape from the side portion of the connection box main body 1 toward the concave portion 7 of the cable holding plate 5. In the moisture-proof cable connecting box, the cable holding portion 9 formed by sandwiching the sheets 8 with a plurality of cables prevents transmission to the cable 20丨 and enters from the outer side of the connecting box body 1 The flow of water droplets in the tank body 1 is connected. In addition, in the case of having water droplets passing through the cable holding portion 9, the water droplets are blocked in the waterproof space 4, and do not further enter the inside of the connection box body 1 and thus 'in the moisture-proof cable connection box Each of the cable holding pieces 8 is -9 - 200839339 (7) formed into a slightly curved shape, and since the cable holding plate 5 is formed inclined, each cable 20 1 will be from the lower side to the upper side (connecting the box body 1) The center portion side is curved, and the water droplets transmitted to the respective cables 201 are dropped to the lower side, thereby being discharged to the outer side of the moisture-proof type cable connecting box. Fig. 7 is an enlarged perspective view showing the vicinity of the shutter plate of the connection box body. As shown in Figs. 6 and 7, in the case where the moisture-proof type cable connecting box has the plurality of cable holding portions 9, the length of each of the cable holding pieces 8 is shorter as it goes higher. Thereby, the closer the cable holding portion 9 on the upper side is to the lower cable holding portion 9, the shorter the length of the cable 20 1 held. As described above, the cable holding plate 5 is inclined toward the side surface side of the connection box body 1 because the waterproof space 4 is slightly triangular. As a result, the distance between the cable holding portion and the cable holding plate 5 becomes narrower as the upper side is higher. The length of the cable holding piece 8 on the upper side is relatively short, thereby preventing the interval between the cable holding portion 9 and the cable holding plate 5 from being too narrow to prevent the cable 20 1 from being sharply bent. Further, at least on the inner side of the uppermost cable holding portion 9, a shutter plate 1 that closes the inner end of the cable holding portion 9 is provided. In this embodiment, the shutter plate 1 is provided at the uppermost cable holding portion 9 and the second cable holding portion 9 from the upper side. The shutter plate 10 is formed of a flexible material such as rubber. When the corresponding cable clamping portion 9 holds the cable 201, the cable 201 is pressed and deformed, and the cable 201 is surrounded. Being closely surrounded. Alternatively, a harder resin may be applied to the shutter plate. At this time, the front end of the shutter plate 1 is not deformed and the cable 201 is pressed to the front side. -10- 200839339 (8) In the moisture-proof cable connection box, the flow of water droplets in the connection box body 1 is prevented from being transmitted to the cable 201 by the shutter plate 10 and from the outer side of the connection box body 1 . In particular, even if it is transmitted to the cable 2 0 1 on the upper side, the water droplets entering the connection box body 1 are large, and although the length of the clamp cable 20 1 is shorter, the shorter the cable holding portion 9 is, but Water resistance is ensured by setting the shutter plate 1 . Further, even in the case of having water droplets that have entered through the shutter plate 10, the water droplets are blocked in the waterproof space 4 and do not enter the connection box body 1 further. The cable holding plate 5 is not only a retaining cable but also has an effect of blocking water droplets transmitted to the cable. Fig. 8 is an enlarged perspective view showing the vicinity of the cable pressing fin of the connection box main body. As shown in Figs. 7 and 8, the junction box main body 1 is provided with a plurality of cable pressing fins 1 at a position on the outer side of the cable introduction portions 1b and 1b. The cable presses the flaps 1, and the front end side is formed in a hook shape. The cable pressing fins 1 1 are arranged neatly between the adjacent pair of cable pressing fins 1 1 and are respectively connected to the corresponding cable holding portions 9. That is, the cable pressing tabs 1 1 are for holding the cable 20 1 held by the cable holding portion 9, and are held such that the cable is made by the hook-shaped front end side portion. 20 1 will not leave. In the moisture-proof cable connection box, the cable 20 1 is clamped to the cable pressing fins 1 1 by the provision of the cable pressing tabs 1, and the hook-shaped front end side is The portion is held to prevent the front side of the junction box body 1 from falling toward the arrow B in Fig. 8 from coming off. The connection box body 1 described above can also be modified as shown in Figs. 9 and 10 to -11 - 200839339 (9). In other words, the cable introduction portion 2 1 b of the present modification is different from the above-described cable introduction portion 1 b in that the upper shutter plate 1 is omitted. Although omitting the shutter plate 10, the effect of blocking the entering water is weakened, but the cable holding piece 28 of the uppermost side and one or more cable holding pieces 2, 8 directly below it are oriented toward the cable. When the holding plate 5 is extended, the waterproofness can be enhanced. The extended cable holding piece 28 is shorter than the other cable holding pieces 8 on the lower side. That is, the cable holding piece 28 is formed such that the cable holding piece on the upper side is sequentially shortened from the lower side. Since any one of the cables 20 1 is guided by the cable holding piece 28, the cable holding portion 29 can be prevented from passing through the cable clamp regardless of the space above the waterproof space 4 and the cable holding plate 5. The cable 201 to which the holding portion 29 is introduced is sharply bent. Since the other parts are the same as those of the connection box body 1 described above, the same reference numerals are attached, and detailed description thereof will be omitted. Further, in the moisture-proof cable connection box, the cover body 2 is opened during the connection work of the optical fiber cable, etc., but since the hinge 3 is at the lower portion of the connection box body 1, it is not required to be used. A brake or the like that maintains the state of the lid body 2 is maintained. Therefore, the number of parts is small and the manufacturing cost is also very low. When the lid body 2 is closed, the lid body 2 is rotated upward by the hinge 3 and then pressed in the depth direction of the joint box body 1, and the claw formed on the upper portion of the lid body 2 is caught. The connection to the box body 1 is stopped, and the cover body 2 is locked so as not to be opened. In this way, when the lid body 2 is closed, the lid body 2 can be simply pressed. [Industrial Availability] -12- 200839339 (10) Provide a cable connection box that is sufficiently moisture-proof to protect the fiber-optic cable from damage.
