Description

Technical Field

[0001] The present invention relates to a wiring box device used for fixing instruments such as surveillance cameras and accommodating cables of the instruments inside.

Background Art

[0002] As one of the above-described wiring box devices, there is one disclosed in Patent Document 1, which includes a fixing portion to which the surveillance camera is fixed for installation of the surveillance camera, and a wiring accommodation space capable of accommodating a connection portion of a cable connected to the surveillance camera and a surplus length portion of the cable.

[0003] The cables accommodated in the wiring accommodation space tend to sag or protrude due to their coiling habits, making it difficult to perform the operation of closing the lid covering the wiring accommodation space. In particular, when the wiring box is installed with the opening facing downward, when the lid is opened, the accommodated cable bundle may sag, imposing a load on the connection portion and hindering maintenance.

[0004] Further, in Patent Document 2, in a branch box body 4 composed of a box-shaped base plate 2 and a lid member 3 covering the opening of the base plate 2, in order to prevent the protrusion of the unit connection cord 24 accommodated in the base plate 2, a protrusion restricting member 52 formed by bending a metal piece is attached to the base plate 2. However, necessary electrical equipment is arranged in the base plate 2, and the space for arranging the surplus length portion of the unit connection cord 24 is limited. The protrusion restricting member 52 prevents the protrusion of the unit connection cord 24 partially arranged in the limited space.

[0005] Therefore, if the proportion of the opening to the front-view area of ​​the wiring box (opening occupancy ratio) is large, that is, if the majority of the front-view area of ​​the wiring box is an opening, it is necessary to cover the excess length of the cable housed within the entire opening with a cable-out prevention member, and the cable-out prevention member 52 disclosed in Patent Document 2 cannot address this. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2022-115245 [Patent Document 2] Japanese Patent Publication No. 2005-191321 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The present invention aims to provide a wiring box device that can prevent cables housed in a cable housing space from coming loose or falling out. [Means for solving the problem]

[0008] The invention of claim 1, which solves the above problem, A wiring box having a box-shaped body with an opening, It consists of a string-like cable escape prevention member that is attached to a mounting part provided on the main body of the wiring box, and is installed so as to cross the opening, thereby preventing the cable housed in the main body from coming out. The invention is characterized by the fact that interference is avoided by deforming the anti-ejection member installed in the opening of the main body, thereby enabling the cable to be housed and positioned inside the main body through the opening.

[0009] According to the invention of claim 1, a string-like anti-flyout member is installed across the opening of the wiring box body to prevent cables housed in the body from sticking out. Furthermore, by deforming the anti-flyout member installed across the opening of the body, interference can be avoided, and cables can be housed in the body from the opening. Therefore, the string-like anti-flyout member can be installed across the opening in accordance with the overall shape of the opening of the body, and can be implemented regardless of the overall shape of the opening, and even for wiring box bodies with openings that occupy a large proportion of the opening. In other words, the string-like anti-flyout member can be installed across an opening of any shape in the wiring box body, preventing excess length of cables housed in the body from sticking out.

[0010] Furthermore, since the anti-ejection member, which is attached across the opening of the main body, is string-like, a large space is formed between each adjacent part of the anti-ejection member. In addition, the anti-ejection member deforms so as not to interfere with the excess length of the cable housed inside the main body from the front side of the opening of the main body. Therefore, with the anti-ejection member installed on the main body, the excess length of the cable can be housed inside the main body, and after the excess length of the cable has been housed, the presence of the anti-ejection member prevents it from flying out. Note that even if the anti-ejection member is attached to the mounting part of the main body after the excess length of the cable has been housed inside the main body, the excess length of the cable can still be prevented from flying out.

[0011] The invention of claim 2 is characterized in that, in the invention of claim 1, the anti-ejection member is extendable in the longitudinal direction.

[0012] According to the invention of claim 2, since the anti-ejection member is extendable in the longitudinal direction, it becomes even easier to avoid interference with the cable when accommodating and arranging the excess length of the cable through the opening in the main body of the wiring box, and the work of accommodating and arranging the excess length of the cable is made easier when the anti-ejection member is installed in the opening of the main body.

[0013] The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the mounting portion is positioned in close proximity to the peripheral wall forming the opening of the main body, and is formed to protrude toward the opening from the bottom side of the main body.

[0014] According to the invention of claim 3, the mounting portion of the main body on which the anti-ejection member is installed is located close to the peripheral wall of the main body, and is less susceptible to external forces within the main body of the wiring box, thus making it less prone to damage. In addition, the installation area of ​​the anti-ejection member within the main body is widened, which also contributes to improving the effect of preventing excess cable length from flying out.

[0015] The invention of claim 4 is the same as claim 1 or 2 In the invention, the wiring box is characterized in that, with the anti-ejection member attached, it is provided with a lid that covers the opening so as to conceal both the mounting portion and the anti-ejection member.

[0016] According to the invention of claim 4, the opening of the main body is closed by the lid, so the inside of the main body is not visible, which improves the appearance of the wiring box.

[0017] The invention of claim 5 is the same as claim 1 or 2 In the invention, the wiring box is fixed to a ceiling wall or the like, with the opening of the main body facing downwards, and the cable fall prevention member is capable of supporting the cable and preventing the cable placed inside the main body from falling out.

[0018] According to the invention of claim 5, if the opening of the wiring box body faces downward and is fixed to a ceiling wall or the like, and the anti-ejection member installed in the opening of the body has sufficient strength, the excess length of the cable housed inside the body with the opening facing downward can be supported, making wiring work easier.

[0019] The invention of claim 6 is, A wiring box having a box-shaped body with an opening, On the opening side of the peripheral wall that forms the opening of the main body, there are a plurality of mounting portions for hooking a string-shaped anti-protrusion member and arranging the anti-protrusion member so as to cross the opening. It is characterized in that an extraction prevention portion for preventing the hooked anti-protrusion member from coming off is formed at the tip of the mounting portion.

[0020] The surplus portion of the cable housed in the main body of the wiring box is hooked by the extraction prevention portion at the tip of each mounting portion and is prevented from protruding by the anti-protrusion member arranged so as to cross the opening of the main body. However, when the surplus portion housed in the main body bulges, a force that pushes the anti-protrusion member forward may act, and there is a risk that the hooking of the anti-protrusion member to each mounting portion will be released. However, according to the invention of claim 6, since an extraction prevention portion for preventing the hooked anti-protrusion member from coming off is formed at the tip of each mounting portion, the hooking state of the anti-protrusion member to the mounting portion is maintained without being released.

[0021] The invention of claim 7 is characterized in that, in the invention of claim 6, the extraction prevention portion is located outside the opening side end portion of the peripheral wall that forms the opening of the main body.

[0022]

[0023] The invention of claim 8 is characterized in that, in the invention of claim 6, the entire mounting portion is arranged inside the main body.

[0024] ​According to the invention of claim 8, since the entire mounting portion for hooking the anti-ejection member is located inside the main body, damage due to external force is less likely to occur, and interference between the mounting portion and the lid is less likely to occur when closing the opening of the main body with the lid. [Effects of the Invention]

[0025] The present invention involves installing an anti-ejection member attached to the mounting portion of the wiring box body across the opening of the wiring box body. Therefore, it can be installed regardless of the overall shape of the opening, and even on wiring box bodies with large openings, preventing excess cable lengths from protruding from the body. Furthermore, because the anti-ejection member installed across the opening of the wiring box body is string-like, large spaces are formed between adjacent parts of the anti-ejection member. In addition, the anti-ejection member deforms from the front side of the opening of the body so as not to interfere with excess cable lengths housed inside the body. Therefore, with the anti-ejection member installed on the body, excess cable lengths can be housed inside the body, and after the excess cable lengths have been housed, the presence of the anti-ejection member prevents them from protruding.

[Figure 9] Figures (a) to (e) show different arrangements of the anti-ejection members A1, A2, and A3 relative to the opening of the box body D. [Figure 10] (a) and (b) are perspective views showing the state in which a surveillance camera device S and a light fixture E are installed on the ceiling wall W using a wiring box device B, respectively. [Modes for carrying out the invention] [Examples]

[0027] The present invention will be described in more detail below with reference to an optimal embodiment. As shown in Figures 1 to 6, the wiring box device B is used to fix equipment such as a surveillance camera device S and to house the excess length Ca of the cable C inside. It consists of a circular box-shaped box body D that houses the excess length Ca of the cable C and is fixed to an object such as a building wall or an outdoor pole, and a circular shallow-bottomed box-shaped lid L that is connected to the box body D in an openable and closable manner to close the opening (opening surface) 10 of the box body D, and the surveillance camera device S is integrally attached to the front of the lid. Both the box body D and the lid L are molded from resin.

[0028] As shown in Figures 2 to 4 and 8, the circular box-shaped box body D is divided into sections by partition walls 2 positioned far from the center of the circle. The majority of this space is a cable storage space 3a for accommodating the excess length Ca of the cable C of the surveillance camera device S, while the remaining small space is a hinge member storage space 3b where the first and second hinge connecting blocks 4 and 5 and the opening stopper 6, which are the main body-side hinge members necessary for hinge-connecting the lid L to the box body D, are arranged. The first and second hinge connecting blocks 4 and 5, which are arranged in the hinge member housing space 3b, are positioned at predetermined intervals along the partition wall 2, and the opening stopper 6 is positioned at predetermined intervals along the partition wall 2 on the opposite side of the first hinge connecting block 4 from the second hinge connecting block 5, and the first and second hinge connecting blocks 4 and 5 and the opening stopper 6, which are the main body side hinge members, protrude from the opening 10 of the box body D, and moreover, the tips of each protrude toward the peripheral wall 1 on the opposite side of the partition wall 2. The first and second hinge connecting blocks 4 and 5 are each formed with pin insertion holes 4a and 5a (see Figure 3) through which the hinge pin 41 described later is inserted.

[0029] The box body D is fixed to the object to be fixed via a plurality of fixing screws 81, and therefore, a plurality of screw holes 11, 12, and 13 are formed through its bottom wall 7 for inserting the fixing screws 81. The purpose of forming the plurality of screw holes 11, 12, and 13 at significantly different locations on the bottom wall 7 is to enable the box body D to be fixed to various shapes of the object to which it is fixed. Specifically, the portion of the peripheral wall 1 of the box body D facing the partition wall 2 has a pair of bulging portions 15 formed in a state that bulges toward the center of the box body D, so that a female screw portion 14 can be formed to screw-fix the portion of the lid L that is hinge-connected to the box body D opposite to the hinge connection portion. The portion of the bulging portion 15 where the female screw portion 14 is formed is a hollow structure, and the female screw portion 14 is formed by a female screw cylinder that is press-fitted into a pilot hole formed in the plate portion on the side of the opening 10. A pair of screw holes 11 are formed through the portion of the bottom wall 7 that reaches the pair of bulging portions 15. In the bottom wall 7 of the portion where each main body hinge member 4, 5, and 6 is located, a pair of screw holes 12 are formed through the wall with the maximum possible spacing between them. In the bottom wall 7 of the cable housing space 3a, which occupies the majority of the space, a total of three pairs of screw holes 13 are provided, symmetrically positioned with respect to the center of the box body D. The portion of the bulging part 15 where the pair of screw holes 11 are formed opens to the side of the opening 10 of the box body D and is a deep hole. Only the three pairs of screw holes 13 are knockout-type screw holes, formed by punching (knockouting) only when necessary to maintain the watertightness of the cable housing space 3a.

[0030] Except for the portion of the box body D's peripheral wall 1 closest to the opening 10, each portion sandwiched between the partition wall 2 and a pair of bulging portions 15 in the depth direction has an outer surface that is concave inward, forming a flat surface, and the peripheral wall 1 in the corresponding portion has an inwardly bulging peripheral wall portion 1a. Each of the opposing inwardly bulging peripheral wall portions 1a has a pair of protective tube connection ports 16 for connecting the end of a protective tube P that houses and protects the cable C, which is routed outside the box body D after the excess length Ca of the cable C is housed in the cable housing space 3a. The protective tube connection ports 16 are covered with cap bodies 17, and when connecting the protective tube P, the cap bodies 17 are removed and the port is used as a protective tube connection port 16. A similar protective tube connection port 16 is formed in the center of the bottom wall 7. By covering each protective tube connection port 16 with a cap body 17 when not in use, the watertightness of the cable housing space 3a can be maintained.

[0031] The inner portion of each inward bulge 1a of the bottom wall 7 is rectangular in front view, and in a longitudinal cross-section along the long side, it is an isosceles trapezoidal shape, forming an inward bulge 7a of the bottom wall, with a recess 18 (see Figure 4) formed outward on each. At the center of the longitudinal direction of each recess 18, and extending from the bottom wall 7, a fixing band hook portion 19 is provided along the short direction. Therefore, by inserting the fixing band 82 into each recess 18 and hooking it onto the fixing band hook portion 19, the box body D can be fixed to poles via the fixing band 82. The side of the rectangular inward bulge 7a of the bottom wall 1 along the short direction is integrally provided with the inward bulge 1a of the bottom wall, while the opposite side of the perimeter wall 1 along the short direction is closed off by a closing plate portion 8, thus isolating it from the outside and ensuring a watertight structure of the inward bulge 7a of the bottom wall.

[0032] A pair of inwardly bulging peripheral wall portions 1a are arranged opposite each other on the bottom wall 7 of the box body D, flanking a protective tube connection port 16. Along the height direction of each inwardly bulging peripheral wall portion 1a, a pair (2) of short rod-shaped mounting portions 21 are provided projecting toward the opening of the box body D at the end closest to the opening 10, for attaching string-like anti-ejection members A1 to A4, such as rubber bands, so that they cross the opening 10. The four mounting portions 21 are all the same shape, and their tips are formed with a roughly T-shaped anti-ejection portion 21a to prevent the string-like anti-ejection members A1 to A4 from coming loose. In other words, the anti-ejection portion 21a only needs to project laterally toward the tip of the mounting portion 21 so as to lock the anti-ejection members A1 to A4 as they try to move toward the tip. Therefore, the shape of the anti-pull-out portion 21a can be various shapes other than the T-shape described above. As clearly shown in Figure 8, each anti-pull-out portion 21a at the tip of each mounting portion 21 protrudes slightly outward from the opening (opening surface) 10 of the box body D, and when the opening 10 of the box body D is covered with the lid L, it slightly enters the cable housing space 35a of the lid L. Note that the opening (opening surface) 10 is shown by a dashed line in Figure 8. The reason for arranging the four short rod-shaped mounting portions 21 for hooking the anti-pull-out members A1 to A4 in the above positions relative to the opening 10 of the box body D is to maximize the effect of preventing the excess length Ca of the cable C housed in the cable housing space 3a from popping out by making the length of the opening 10 crossed by the anti-pull-out members A1 to A4, and the total length of the crossing, as long as possible.

[0033] By forming an anti-pull-out portion 21a at the tip of each mounting portion 21, the anti-ejection members A1 to A4 are kept hooked to the mounting portion 21 without being released. In particular, if each anti-pull-out portion 21a at the tip of each mounting portion 21 is formed to protrude slightly outward from the opening (opening surface) 10 of the box body D, a wider cable housing space 3a of the box body D can be secured, and the anti-ejection members A1 to A4 can be hooked to the mounting portion 21 without interfering with the opening-side end of the peripheral wall 1 of the box body D, making it easier to install the anti-ejection members A1 to A4 across the opening 10 of the box body D.

[0034] However, it is also possible to place the entire mounting portion 21 inside the box body D. In this case, the anti-pull-out portions A1 to A4 can be hooked onto each mounting portion 21 without interfering with the opening end of the peripheral wall 1 of the box body D, making it easier to install the anti-pull-out members A1 to A4 across the opening of the main body.

[0035] Furthermore, as shown in Figure 8, by forming a pair of opposing inward bulges 1a on the peripheral wall 1, the portion of the peripheral wall 1 where each inward bulge 1a is formed becomes a flange-shaped peripheral wall portion 1b that remains in a partial flange shape relative to each inward bulge 1a, only in the portion close to the opening 10. As a result, each mounting portion 21 is positioned close to each flange-shaped peripheral wall portion 1b. The reason for positioning each mounting portion 21 in the above location is that placing the string-like anti-flyout members A1 to A4 over as wide an area as possible in the opening 10 of the box body D effectively prevents the excess length Ca of the cable C housed in the cable housing space 3a of the box body D from flying out, and that positioning them as close as possible to the peripheral wall 1 makes it difficult for external forces to act inside the box body D, thereby preventing damage to the mounting portion 21. In Figures 2, 7, and 8, 1c indicates a thin-walled sealing wall portion provided at the end of the peripheral wall 1 and partition wall 2 that form the cable housing space 3a, on the side of the opening 10, and inserted into the packing groove 37 of the cover L.

[0036] Next, with reference to Figures 2 and 6 to 8, the lid L that covers the opening 10 of the box body D will be described. The lid L is a shallow, circular box shape corresponding to the overall shape of the box body D, and consists of a bottom wall 31 and a peripheral wall 32 with an arc-shaped cross-section. The internal space of the lid L is partitioned by partition walls 33 positioned at locations corresponding to the partition walls 2 of the box body D, and consists of a cable housing space 35a in which an oval-shaped equipment fixing part 34 is formed inwardly with a thickened surface into which a plurality of fixing screws 83 for fixing the fixing flange portion 84 of the base end of the surveillance camera device S to the lid L is screwed, and a hinge member housing space 35b in which the hinge member on the lid L side is housed. On the underside of the lid L, two inward bulges 32a are formed, corresponding to the two bulges 15 of the box body D. Each inward bulge 32a has a through hole 36 for a fixing screw 85 that secures the lid L to the box body D on the side opposite to the hinge connection. The fixing screw 85 is screwed into the female threaded portion 14 of the box body D. The overall shape of the cable housing space 35a is formed by the portion of the periphery wall 32 excluding the hinge member housing space 35b, the partition wall 33, and the bulging ends of the pair of inward bulges 32a being formed in a continuous manner. A packing groove 37 into which a seal packing 86 (see Figure 8) is inserted is continuously formed at the opening end of this continuous portion.

[0037] The oval-shaped fixture fixing portion 34 on the bottom wall 31 of the lid L, to which the fixing flange portion 84 of the surveillance camera device S is fixed, is formed thickly, bulging into the inner cable housing space 35a. As shown in Figure 8, on the outer and inner surfaces of the oval-shaped fixture fixing portion 34, numerous non-penetrating screw holes 38a and 38b are formed in pairs with the same axis, into which fixing screws 83 for fixing the fixing flange portion 84 of the surveillance camera device S are screwed. This allows the fixing screws 83 to be screwed into any position on the fixture fixing portion 34, making it easy to fix the surveillance camera device S to the wiring box device B. The numerous screw holes 38a and 38b, formed in pairs with the same axis, are non-penetrating, which allows the fixing screws 83 to be screwed in while ensuring watertightness of the bottom wall 31 of the lid L.

[0038] In the hinge member housing space 35b of the lid L, first and second hinge pin insertion supports 42 and 43 are arranged at predetermined intervals (the same interval as the interval between the first and second hinge connecting blocks 4 and 5 of the box body D) along the axial direction of the hinge pins 41, and are connected to the first and second hinge connecting blocks 4 and 5 arranged in the box body D via two hinge pins 41. The first and second hinge pin insertion supports 42 and 43 each have pin insertion holes 42a and 43a (see Figure 5(b)) through which the hinge pins 41 are inserted. Therefore, as shown in Figure 2, the first and second hinge pin insertion supports 42 and 43 of the lid L are positioned above the first and second hinge connecting blocks 4 and 5 of the box body D, respectively. The hinge pins 41 are inserted through the pin insertion holes 4a and 42a of the first hinge connecting block 4 and the first hinge pin insertion support 42 to connect them, and the hinge pins 41 are also inserted through the pin insertion holes 5a and 43a of the second hinge connecting block 5 and the second hinge pin insertion support 43. As a result, the box body D and the lid L are hinged together via the two hinge pins 41 so that they can be opened and closed. In addition, the opening stopper 6 of the box body D abuts against and locks into the notch 42b (see Figure 2) provided on the first hinge pin insertion support 42 of the lid L, thereby restricting the maximum opening angle of the lid L relative to the box body D. As shown in Figure 2, a slide contact body 9 is located directly below the first hinge connecting block body 4 of the box body D. By sliding in a direction perpendicular to the axis of the hinge pin 41 in the hinged state, the slide contact body 9 can be partially positioned and retracted relative to the upper surface of the second hinge pin insertion support 43 of the lid L, enabling the maintenance and release of the hinge connection between the box body D and the lid L. In other words, the box body D and the lid L are inseparably connected to each other via a hinge connecting mechanism H composed of the aforementioned hinge connecting members provided on each side. To separate the box body D and the lid L, the slide contact body 9 is retracted to release contact with the second hinge pin insertion support 43 on the lid L side, and the box body D and the lid L are slid in one axial direction of the hinge pin 41.

[0039] Furthermore, in the portions corresponding to the through holes 36 through which the pair of fixing screws 85 pass on the front side of the lid L, recesses 44 are formed extending from the bottom wall 31 to the peripheral wall 32 to accommodate the heads of the fixing screws 85. When the lid L opposite the hinge connection portion is fixed to the box body D using the pair of fixing screws 85, these recesses 44 are closed by the cap body 45, thereby ensuring a good appearance.

[0040] With the box body D and the lid L connected via a hinge connection mechanism H, when the lid L is rotated relative to the box body D to close the opening 10 of the box body D, as shown in Figure 8, the tip of the sealing wall portion 1c of the box body D is inserted into the packing groove 37 of the lid L into which the sealing packing 86 is inserted, thereby closing the opening 10 of the box body D while maintaining a watertight seal at the contact point between the two D and L.

[0041] To fix electrical equipment such as a surveillance camera device S to a wiring box device B fixed to a building wall or an outdoor pole or other fixed object, the following procedure is followed. For example, as shown in Figures 7 and 8, if the fixed object is a vertical wall W1 of a building, the fixing is done by using the pair of screw holes 11 and 12 provided in the pair of bulging portions 15 and hinge member housing space 3b of the box body D, and screwing the fixing screws 81 inserted through the screw holes 11 and 12 into the wall W1. When screwing the fixing screws 81 inserted through the pair of screw holes 12 into the wall W1, this is done with the lid L not connected to the box body D. If the pair of screw holes 11 and 12 cannot be used, multiple screw holes 13 formed in the center of the bottom wall 7 are selected, and the box body D is fixed to the wall W1 using multiple fixing screws 81.

[0042] With the box body D fixed to the wall surface W1, if an anti-ejection member A1, which is made of an endless, expandable rubber band, is hooked onto the four short rod-shaped mounting parts 21 of the box body D in an X shape with a predetermined tension applied, as shown in Figure 7, the anti-ejection member A1 will be positioned to cross the opening 10.

[0043] The wiring of cable C connected to the surveillance camera device S is routed through a cable insertion opening 46 formed in the center of the equipment fixing part 34 of the lid L. Cable C is inserted through the cable insertion opening 46 from the outside, and the power and video connection wires at the end of cable C are connected via connectors 91 and 92 to power and video extension cables C' and C'' drawn from a protective tube P connected to a specific protective tube connection opening 16 in the inward bulging part 1a of the peripheral wall of the box body D. The excess length Ca of cable C between the connection part of the protective tube P connected to the box body D and the cable insertion opening 46 of the lid L is contained in the gap between the anti-ejection member A1, which is made of rubber bands arranged in an X shape in the opening 10 of the box body D, and the peripheral wall (part of the peripheral wall 1 of the box body D and the partition wall 2) that forms the cable housing space 3a. The cable is bundled and placed within the cable storage space 3a. Since the rubber band constituting the anti-ejection member A1 is stretchable, the excess portion Ca of the cable C can be placed in the cable storage space 3a while avoiding interference with the anti-ejection member A1 by shifting the anti-ejection member A1 to the side. After the excess portion Ca of the cable C is placed in the cable storage space 3a, the anti-ejection member A1, which has been shifted to the side to avoid interference with the excess portion Ca of the cable C, returns to its original X shape due to its elastic restoring force, thereby preventing the excess portion Ca of the cable C placed in the cable storage space 3a from sticking out. Alternatively, after the excess portion Ca of the cable C is placed in the cable storage space 3a of the box body D, the anti-ejection member A1, made of rubber bands, may be hooked in an X shape onto each of the four mounting parts 21.

[0044] Finally, the opening 10 of the box body D, which is fixed to the vertical wall surface W1, is closed with the lid L, and with the lid L fixed to the box body D by two fixing screws 85, the fixing flange portion 84 of the surveillance camera device S is fixed to the equipment fixing portion 34 on the front of the lid L via multiple fixing screws 83. Each of the three fixing screws 83 is screwed into one of the numerous non-penetrating screw holes 38a, 38b formed on the same axis in the equipment fixing portion 34, thereby fixing the surveillance camera device S to the front of the wiring box device B. Furthermore, since the fixing flange portion 84 of the surveillance camera device S is in close contact with the flat upper surface of the fixture fixing portion 34 of the lid L of the wiring box device B, even if numerous screw holes 38a are formed on the front surface of the fixture fixing portion 34 and a cable insertion opening 46 is formed in the center of the fixture fixing portion 34, watertightness is ensured between the front surface of the fixture fixing portion 34 of the lid L and the back surface of the fixing flange portion 84 of the surveillance camera device S. If a watertight packing is interposed between the two surfaces, the watertightness can be further enhanced.

[0045] Furthermore, the arrangement of the anti-ejection members A1 to A4 in relation to the opening 10 of the box body D is not limited to the X shape described above, and various arrangements are possible. The material of the anti-ejection members A1 to A4 is not limited to a single endless rubber band with elasticity, but can also be wire, string, etc. Figure 9(a) shows the anti-ejection member A1 made of a single rubber band arranged in an X shape within the opening 10, Figure 9(b) shows the anti-ejection member A2 made of an endless rubber band used, with each anti-ejection member A2 arranged diagonally and crossing to form an X shape within the opening 10, or as shown in Figure 9(c), the two anti-ejection members A2 can be arranged vertically within the opening 10 at a predetermined horizontal distance. Furthermore, Figure 9(d) shows an example where a single wire-based anti-ejection member A3 is arranged in an X-shape within the opening 10, and Figure 9(e) shows an example where a single string-based anti-ejection member A4 is hooked onto each mounting part 21 in a rectangular shape, thereby arranging them vertically at predetermined horizontal intervals within the opening 10. Anti-ejection members A1 and A2, which are made of elastic rubber bands, can be "pre-attached" to the box body D, and even if they are moved laterally to avoid interference with the excess length Ca of the cable C when accommodating the cable C in the cable accommodation space 3a of the box body D, they will return to their original position due to their elasticity. However, it is preferable to "post-attach" anti-ejection members A3 and A4, which are made of wire or string, by attaching them to each mounting part 21 and crossing the opening 10 after the excess length Ca has been accommodating the cable C in the cable accommodation space 3a of the box body D. Furthermore, when pre-installing the anti-fly-out members A3 and A4, which are made of wire or string, it is desirable to install them with a predetermined amount of slack to avoid interference with the excess length Ca of the cable C. In addition, after moving each of the anti-fly-out members A1 to A4 to the side to avoid interference, each of the anti-fly-out members A1 to A4 should be returned to a position where it can prevent the excess length Ca from flying out.

[0046] Furthermore, the flyout prevention member may have a structure in which only a part of it expands and contracts. That is, the flyout prevention member may be formed of an expandable and contractible elastic material only in the portion that is positioned to cross the opening 10 of the box body D, while the portion that does not cross the opening 10 of the box body D and is mounted on two mounting parts 21 provided on the same peripheral wall inward bulge 1a may be made of a non-expandable material.

[0047] Furthermore, as shown in Figure 10(a), the surveillance camera device S may also be installed on the ceiling wall W2 of the building. In this case, by using the anti-ejection members A1 and A2, which are made of elastic rubber bands as shown in Figures 9(a) to (c), the excess length Ca of the cable C is housed in the cable housing space 3a of the box body D, with the opening 10 facing downwards. The excess length Ca is then held in place by the anti-ejection members A1 and A2, which are positioned across the opening 10, thereby preventing it from falling. Therefore, wiring work performed with the opening 10 of the box body D facing downwards is difficult in terms of housing the excess length Ca of the cable C in the cable housing space 3a of the box body D and maintaining that housing state. However, by using the anti-ejection members A1 and A2, which are made of elastic rubber bands, this difficulty is resolved, and wiring work can be performed relatively easily.

[0048] Furthermore, as shown in Figure 10(b), it is also possible to install the light fixture E on the ceiling wall W2 using the wiring box device B.

[0049] Furthermore, in the above embodiment, the box body D and the lid L are hinged together via a hinge connection mechanism H, but the configuration of the hinge connection mechanism H is not limited to the above embodiment and may be any structure. The box body D and the lid L may also be configured such that a separate lid L covers the box body D without hinge connection.

[0050] The overall shape of the wiring box device B is not limited to the circular shape described above, but may also be rectangular. [Explanation of Symbols]
