Description

Technology Field

[0001] The present invention relates to a fixing device for wiring devices that can easily and securely install wiring devices, such as connectors or switches, embedded therein during partition construction on an interior wall, on a partition wall.

[0002] More specifically, the present invention relates to a wiring box for a wiring device that is convenient to use by enabling the wiring device fixing device, on which a wiring device is mounted, to be installed horizontally and accurately through various structural improvements, such as a separate wiring device fixing member having screw fastening holes formed in insertion parts formed on the upper and lower front sides of the box body constituting the wiring box, which is coupled so as to be movable left and right. This is achieved by moving the wiring device fixing member left and right or, if necessary, up and down to align the bolt fastening hole with the screw insertion hole formed in the wiring device fixing device and then fastening it with a screw. Background Technology

[0003] Generally, as shown in FIGS. 1 and 2, various electrical wiring devices (61)(71), such as connectors, switches, telephone lines, internet, TV antenna lines, and optical cables, are installed on the walls of various buildings. When looking at the installation state of the wiring devices (61)(71), a wiring device fixing panel (60)(70) on which the various wiring devices (61)(71) are mounted is connected to a wiring box (50) that is embedded or fixedly installed in the wall by fastening it with a bolt (75). After aligning the bolt fastening hole (52) integrally formed in the wiring box (50) with the bolt insertion hole (63)(73) formed in the wiring device fixing panel (60)(70), the fixing bolt (75) is fastened through the bolt insertion hole (63)(73) to the bolt fastening hole (52) to fix the installation, and then a finishing cover (80) is attached to the wiring device fixing panel (60)(70) in a manner that various A wiring device (61) (71) was installed (see Patent Registration No. 10-0883666).

[0004] That is, the wiring box (50) is typically made of metal and formed by being recessed into the interior of the building wall. The wiring device fixing panel (60) (70) made of synthetic resin, on which various wiring devices (61) (71) are mounted, is bolted (75) into the bolt fastening hole (52) provided in the bolt fastening hole forming part (51) formed integrally at the upper and lower ends of the wiring box (50), and then the finishing cover (80) is attached.

[0005] However, in the conventional wiring box (50) and various wiring fixture fixing panels (60)(70) combined structure, even if the wiring box is initially installed horizontally and vertically in a precise manner, if the fixing bolt (75) is tightened too strongly, the wiring fixture fixing panel (60)(70), which is made of synthetic resin, may easily become twisted or, in severe cases, damaged, and thus the force cannot be applied beyond a certain level, so the connection state between the wiring box (50) and the wiring fixture fixing panel (60)(70) becomes unstable. Furthermore, if the wiring fixture fixing panel (60)(70) is damaged in this way, the connection hole of the finishing cover (80) installed on the front surface becomes misaligned with the connection hole of the wiring fixture (61)(71), which lowers the external aesthetic appeal and makes it difficult to insert and connect a plug or connector, and the finishing cover (80) is easily detached during use, resulting in a decrease in stability.

[0006] Accordingly, a technology has been disclosed in which the wiring device fixing panel is constructed of a solid metal material. However, in this case, if the connection position with the wiring box (50)—that is, the bolt fastening hole (52) formed in the wiring box (50) and the bolt insertion hole (63)(73) formed in the wiring device fixing panel (60)(70)—does not align exactly, it is very difficult to tighten the bolt (75) and it is difficult to tighten it completely. Furthermore, since the cost of the metal material increases significantly, there was a problem of relatively large economic loss compared to conventional products made of synthetic resin material.

[0007] Meanwhile, when the wiring box (50) is fixed to the wall, unlike the former, if it is fixed so that it is crooked to the left or right and not level,

[0008] This also still had the fundamental problem that no matter how accurately the wiring fixture fixing panel (60)(70) was installed horizontally, the position of the bolt insertion hole (63(73)) formed in the wiring fixture fixing panel (60)(70) and the bolt fastening hole (52) of the wiring box (50) installed crookedly would be slightly misaligned, making it difficult to fasten the bolt (75), which would make the work inconvenient and time-consuming, and even if the bolt were fastened by force, the wiring fixture fixing panel (60)(70) would not be installed perfectly horizontally. The problem to be solved

[0009] The present invention has been devised in consideration of the aforementioned conventional problems, and

[0010] The purpose of this invention is to provide a high-quality wiring box for wiring devices that allows for the accurate horizontal installation of a wiring device fixing device equipped with a wiring device, by making various structural improvements such as a separate wiring device fixing member having screw fastening holes formed in insertion parts formed on the upper and lower front sides of the box body constituting the wiring box, which is coupled so as to be movable left and right, so that even if the wiring box of the present invention is fixedly installed crookedly to the left or right and not level, the wiring device fixing member can be moved left and right or, if necessary, up and down to align the bolt fastening hole with the screw insertion hole formed in the wiring device fixing device and then screw fastening, thereby enabling the wiring device fixing device to be installed horizontally and conveniently. means of solving the problem

[0011] The wiring box for a wiring device according to the present invention, which is intended to achieve the purpose described in the problem to be solved above, is basically a wiring box for a wiring device that fixes electrical wiring devices such as connectors, switches, telephone lines, internet, TV antenna lines, and optical cables to a wall,

[0012] The above wiring box has a box-shaped body with a box-like structure that has a plurality of wiring inlet holes and an open front, and has insertion parts of a predetermined shape formed on the upper and lower front sides of the box body.

[0013] A separate wiring fixture fastening member with a screw hole formed in the above insertion part is inserted and assembled so as not to fall out to the outside,

[0014] The above wiring mechanism fixing member is configured to be movable left and right while coupled to the insertion part,

[0015] The feature is that a screw can be easily fastened to a screw fastening hole formed in a wiring fixture fastening member through a screw insertion hole formed in a wiring fixture fixing member equipped with a wiring fixture.

[0016] In this invention, a step is formed in the insertion portion formed on the upper and lower front sides of the box body, and

[0017] The above-mentioned wiring fixture fixing member is configured such that a stepped catch plate is formed at the rear end and anti-detachment protrusions are formed on both the front and rear sides thereof, so that when the wiring fixture fixing member is inserted into the insertion part, the stepped catch plate is inserted up to the step, and at the same time, the anti-detachment protrusions pass through the step and catch on the inside of the step, thereby preventing the wiring fixture fixing member from detaching from the insertion part. Effects of the invention

[0018] The wiring box for a wiring device that facilitates the installation of the wiring device according to the present invention basically has a revolutionary improvement in its structure, such as allowing a separate wiring device fixing member, which has a screw fastening hole formed in an insertion part formed on the upper and lower front sides of the box body constituting the wiring box, to be movable left and right. This allows the wiring box of the present invention to be fixed in a way that is crooked left and right and not level, so that even if the wiring box of the present invention is fixed in a way that is not level, the wiring device fixing member can be moved left and right to align the bolt fastening hole with the screw insertion hole formed in the wiring device fixing member and then screw fastened, thereby having the advantage of being able to accurately install the wiring device fixing member equipped with the wiring device (210) in a horizontal position.

[0019] In addition, the present invention has the advantage that when a screw is fastened to the screw fastening hole formed in the wiring fixture fastening member through the screw insertion hole formed in the wiring fixture fastening member, the end of the screw moves along the inclined surface of the entrance side, allowing for easy fastening.

[0020] In addition, the present invention has the advantage of allowing multiple wiring boxes to be selectively connected and used according to the number of electrical wiring devices installed, such as connectors, switches, telephone lines, internet, TV antenna lines, and optical cables, because various types of connecting holes, such as protrusions or protrusion coupling holes, are further formed at corresponding positions on each side of the box body of the wiring box.

[0021] Meanwhile, the present invention is configured such that the wiring mechanism fixing member can move left and right while coupled to the insertion part, and at the same time,

[0022] By configuring the wiring mechanism fixing member (120) so that a fine gap is formed between the step formed in the insertion part and the anti-detachment projection formed on the wiring mechanism fixing member, the wiring mechanism fixing member (120) can be moved up and down by the amount of the fine gap,

[0023] The wiring box of the present invention is installed on a wall at a slight angle to the left and right, as well as at a slight angle to the top and bottom. Since the distance between the screw fastening holes can be finely adjusted not only to the left and right and up and down even if the distance between the screw fastening holes is slightly varied, there are various advantages such as being able to easily fix and install a wiring device fixing fixture equipped with a wiring device in both horizontal and vertical directions.

[0024] Therefore, the present invention is a very groundbreaking invention that can be very useful in practical use. Brief explanation of the drawing

[0026] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, FIGS. 3 to 14. The embodiments described below are presented as examples to aid in understanding the present invention, and it should be understood that the present invention may be implemented in various modified forms different from the embodiments described herein. However, in describing the present invention, if it is determined that a detailed description of related known functions, components, or known methods may unnecessarily obscure the essence of the present invention, such detailed description and specific illustration are omitted. Furthermore, the attached drawings are not drawn to the actual scale to aid in understanding the invention, and the dimensions of some components may be exaggerated.

[0027] As shown in the attached drawings Figs. 3 to 14, the wiring box for the wiring device of the present invention is basically manufactured in a square or rectangular shape, but is not limited to this rectangular shape and can be manufactured in various shapes as needed.

[0028] First, the wiring box for wiring devices of the present invention is used to fix various wiring devices (210), such as connectors, switches, telephone lines, internet, TV antenna lines, and optical cables, to a wall. Looking at the basic configuration of the wiring box (100) for wiring devices of the present invention, a plurality of wiring inlet holes (111) are formed, and a box-shaped box body (110) with an open front has insertion parts (112) of a predetermined shape formed on both the upper and lower sides of the front.

[0029] And a wiring mechanism fixing member (120), separately manufactured to form a screw fastening hole (121) including a circular or square shape, is inserted into this insertion part (112) and assembled so as not to fall out to the outside.

[0030] At this time, the wiring mechanism fixing member (120) is configured to be movable left and right while connected to the insertion part (112),

[0031] The screw (220) can be easily fastened to the screw fastening hole (121) formed in the wiring device fastening member (120) through the screw insertion hole (201) formed in the wiring device fixing member (200) equipped with the wiring device (210).

[0032] Herein, as an example of an assembly structure of an insertion part and a wiring mechanism fixing member, the present invention forms a step (112a) on the insertion part (112) formed on the upper and lower front sides of the box body (110), and

[0033] The above wiring mechanism fixing member (120) may be configured such that when the wiring mechanism fixing member (120) is inserted into the insertion part (112), the step catch plate (122) is inserted up to the step (112a) and the detachment prevention protrusion (123) passes through the step (112a) and is caught inside the step (112a), thereby preventing the wiring mechanism fixing member (120) from detaching from the insertion part (112), but is not limited thereto.

[0034] In addition, the present invention relates to a screw fastening hole (121) formed in the wiring mechanism fixing member (120).

[0035] In particular, as shown in FIGS. 7a and 7b, the inlet side (121a) can be formed with a wide slope. In this way, when a screw (220) is fastened to the screw fastening hole (121) formed in the wiring fixture fastening member (120) through the screw insertion hole (201) formed in the wiring fixture fastening member (200), the end of the screw (220) moves along the sloped surface of the inlet side (121a) and is easily fastened.

[0036] In addition, the present invention further forms various types of connecting holes (130), such as protrusions or protrusion coupling holes, at corresponding positions on each side of the box body (110) of the wiring box (100).

[0037] Multiple wiring boxes (100) can be selectively connected and installed according to the number of electrical wiring devices (210) such as connectors, switches, telephone lines, internet, TV antenna lines, and optical cables.

[0038] In addition, the present invention further forms a wing portion (140) and a wing coupling portion (150) at corresponding positions on the rear surface of each box body (110) of the wiring box (100), wherein the wing portion (140) is provided with a locking groove (141) and the wing coupling portion (150) is provided with a locking projection (151).

[0039] When connecting wiring boxes (100) to each other, if the wing portion (140) is connected to the wing coupling portion (150), the locking projection (151) provided in the wing coupling portion (150) is connected to the locking groove (141) provided in the wing portion (140), so that multiple wiring boxes (100) can be connected and installed more securely.

[0040] In addition, the present invention is configured to further attach a foreign matter inflow prevention cover (160) to the outside of the insertion parts (112) formed on the upper and lower front sides of the box body (110),

[0041] When installing the wiring box (100), foreign matter can be prevented from entering the insertion part (112), thereby ensuring that there is no hindrance to the left and right movement of the wiring mechanism fixing member (120).

[0042] In addition, the present invention is configured such that the wiring mechanism fixing member (120) can move left and right while coupled to the insertion part (112), and at the same time,

[0043] The screw fastening holes (121) are configured to be movable up and down so that the distance between them can be adjusted.

[0044] When manufacturing, storing, and installing the above wiring box (100) and wiring fixture fixing device (200), even if the left-right and up-down distance widths formed by a pair of screw fastening holes (121) vary slightly, the distance width between the screw fastening holes (121) can be adjusted so that screw (220) fastening can be made easier.

[0045] At this time, in order to make the upper and lower distance between the screw fastening holes (121) formed in the wiring mechanism fixing member (120) adjustable,

[0046] In particular, as shown in FIG. 7b, a fine gap is formed between the step (112a) formed on the insertion part (112) and the anti-detachment projection (123) formed on the wiring mechanism fixing fastening member (120),

[0047] The wiring mechanism fixing member (120) may be configured to be moved up and down by a fine gap.

[0048] This configuration is also applied to other configuration examples of other embodiments of the present invention.

[0049] The usage state of the wiring box for a wiring device according to the above-described embodiment of the present invention is as follows.

[0050] First, since the wiring box for the wiring device of the present invention has a wiring device fixing member (120) with a separately manufactured screw fastening hole formed therein, the separately manufactured wiring device fixing member (120) is first inserted into the insertion part formed on the upper and lower front sides of the box body (110) of the wiring box (100), and inserted so that the screw fastening hole protrudes into the interior of the box body.

[0051] Then, a step (112a) is formed on the insertion part (112) formed on the upper and lower front sides of the box body (110), and the wiring mechanism fixing fastening member (120) has a step catch plate (122) formed at the rear end and anti-detachment projections (123) formed on the front front and rear sides thereof, so,

[0052] When the wiring mechanism fixing member (120) is inserted into the above insertion part (112), the step catch plate (122) is inserted only up to the step (112a), and at the same time, the anti-detachment projection (123) passes through the step (112a) and gets caught on the inside of the step (112a).

[0053] Accordingly, the wiring mechanism fixing member (120) is coupled so that it does not detach from the insertion part (112).

[0054] At this time, since the left and right width of the step catch plate (122) formed on the wiring mechanism fixing member (120) is configured to be smaller than the left and right width of the insertion part (112) formed on the box body, the wiring mechanism fixing member (120) can move left and right.

[0055] In addition, if a foreign matter inflow prevention cover (160) is further attached to the outside of the insertion part (112) formed on the upper and lower sides of the front of the box body (110), foreign matter cannot be introduced into the insertion part (112) when the wiring box (100) is fixedly installed on the wall, thereby ensuring that there is no hindrance to the left and right movement of the wiring mechanism fixing member (120). This configuration can be used when the wiring box (100) is fixedly installed so as to be directly buried inside the wall, and it is not necessary to use it when the wiring box (100) is fixedly installed behind the wall panel (partition).

[0056] As described above, the wiring box, which is equipped with a wiring fixture fixing member (120) that allows for left and right movement, is distributed and then embedded in the walls of various buildings.

[0057] At this time, it is natural that the wiring box of the present invention, as well as other wiring boxes previously devised, must be accurately fixed and installed horizontally and vertically on the wall, but in reality, depending on the skill level of the worker, there were often cases where they were installed slightly tilted to the left or right.

[0058] Even if the wiring box is installed crookedly to the left or right, the wiring device fixing device (200) equipped with the wiring device (210) must be fixed and installed accurately in a horizontal position, but

[0059] In the case of existing wiring boxes, the bolt-forming part with the bolt fastening hole is manufactured integrally with the box body, so,

[0060] Once the wiring box is fixed in place crookedly to the left or right,

[0061] Even if one attempts to install the wiring fixture fixing device accurately horizontally, the screw insertion hole formed in the wiring fixture fixing device and the bolt fastening hole of the crookedly installed wiring box are slightly misaligned, making it difficult to fasten the screw, which is inconvenient and time-consuming to work, and even if the screw is forcibly fastened, the wiring fixture fixing device is not installed horizontally.

[0062] However, in the case of the wiring box of the present invention, a separate wiring mechanism fixing member (120) having a screw fastening hole (121) formed in the insertion part (112) formed on the upper and lower front sides of the box body (110) constituting the wiring box (100) is coupled so as to be movable left and right,

[0063] Even if the wiring box (100) of the present invention is installed crookedly to the left and right and not level, the wiring device fixing member (120) can be moved left and right to align the bolt fastening hole (121) with the screw insertion hole (201) formed in the wiring device fixing member (200) and then fastened with a screw (220), so the wiring device fixing member (200) with the wiring device (210) mounted thereon can be installed accurately in a horizontal position.

[0064] In addition, in this invention, the entrance side (121a) of the screw fastening hole (121) formed in the wiring mechanism fixing member (120) is formed to be widely inclined, so when the screw (220) is fastened to the screw fastening hole (121) formed in the wiring mechanism fixing member (120) through the screw insertion hole (201) formed in the wiring mechanism fixing member (200), the end of the screw (220) moves along the inclined surface of the entrance side (121a) and is easily fastened.

[0065] In addition, since the present invention further forms various types of connecting holes (130), such as protrusions or protrusion coupling holes, at corresponding positions on each side of the box body (110) of the wiring box (100), multiple wiring boxes (100) can be selectively connected and installed to match the number of electrical wiring devices (210) such as connectors, switches, telephone lines, internet, TV antenna lines, and optical cables.

[0066] In this case, as seen in another configuration example of the present invention, a wing portion (140) and a wing coupling portion (150) are further formed at corresponding positions on the rear surface of each box body (110) of the wiring box (100). In this case, when the wing portion (140) is provided with a locking groove (141) and the wing coupling portion (150) is provided with a locking projection (151), when the wiring boxes (100) are connected to each other, the wing portion (140) is connected to the wing coupling portion (150), and the locking projection (151) provided in the wing coupling portion (150) is connected to the locking groove (141) provided in the wing portion (140), so that multiple wiring boxes (100) can be connected and installed more securely.

[0067] Meanwhile, the present invention is configured such that the wiring mechanism fixing member (120) is coupled to the insertion part (112) and can move left and right, and at the same time,

[0068] A fine gap can be formed between the step (112a) formed in the insertion part (112) and the anti-detachment projection (123) formed in the wiring mechanism fixing member (120) (see FIG. 7b), so that the wiring mechanism fixing member (120) can be moved up and down by the amount of the fine gap. Then, the wiring box (100) of the present invention can be installed on the wall so as to be slightly tilted to the left and right, and also installed so as to be slightly tilted up and down when viewed from the side. Even if the left and right and up and down distance widths formed by a pair of screw fastening holes (121) change slightly, the distance width between the screw fastening holes (121) can be finely adjusted not only to the left and right but also up and down, so the wiring mechanism fixing member (200) with the wiring mechanism mounted can be easily fastened horizontally and vertically with a screw (220).

[0069] As a result, the wiring mechanism for the wiring box of the present invention has various structural peculiarities, such as a separate wiring mechanism fixing member (120) having a screw fastening hole (121) formed in the insertion part (112) formed on the upper and lower front sides of the box body (110) constituting the wiring box (100), which is coupled so as to be movable left and right. Therefore, even if the wiring box (100) of the present invention is initially installed crookedly to the left and right and not level, the wiring mechanism fixing member (120) can be moved left and right or up and down if necessary to align the bolt fastening hole (121) with the screw insertion hole (201) formed in the wiring mechanism fixing member (200) and then fastened with a screw (220). Thus, the wiring mechanism fixing member (200) with the wiring mechanism (210) mounted thereon can be installed horizontally in a simple, quick, and accurate manner.

[0070] As described above, although the present invention has been explained by limited embodiments and drawings, it is not limited by these embodiments, and it is obvious that various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.
