Description

Technical Field

[0001] This utility model belongs to the field of junction box technology, and in particular relates to a splicing junction box. Background Technology

[0002] Junction boxes are electrical accessories used in home decoration to protect and connect wires. They can be divided into plastic junction boxes and metal junction boxes. Depending on the application, they can also be divided into outdoor junction boxes and indoor junction boxes. Outdoor junction boxes are waterproof, dustproof, and corrosion-resistant, and are suitable for outdoor wiring. Indoor junction boxes are mostly used for electrical wiring connections inside buildings. They are usually buried and have panels for connecting switches or sockets installed on them.

[0003] When multiple junction boxes are placed side by side, traditional decorators usually arrange them according to their feel and fill the gaps with cement to fix them in place. Due to differences in the decorators' feel and experience, as well as uncontrollable factors in the cement filling process, it is often difficult to achieve a neat and uniform arrangement of the junction boxes. This not only affects the aesthetics of the entire wall, but may also cause difficulties in the subsequent installation of socket and switch panels, as well as affect the aesthetics of the installed panels. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a modular junction box that allows multiple junction boxes to be spliced ​​together when installed side by side, thereby improving the connection stability between the multiple junction boxes and achieving a neat and uniform appearance after installation.

[0005] In view of this, the present invention provides a modular junction box, comprising: The housing has a wiring cavity for wiring; The splicing panel is installed at the bottom of the box and is used to connect and fix two adjacent boxes. The bottom of the box has multiple connecting posts, and the splicing plate has multiple connecting holes for fixed insertion with the connecting posts.

[0006] In the above technical solution, further: The bottom surface of the box has a groove that fits the splicing plate, and the connecting column is installed on the inner wall of the groove; The connecting column is flush with the bottom surface of the box.

[0007] Furthermore, the above technical solution also includes: A boss is installed on the side of the box, and the bosses of two adjacent boxes abut against each other; The surface of the boss away from the box is flat.

[0008] In the above technical solution, further: The boss has a socket, and the socket is connected to a panel fixing piece; The panel fixing piece is L-shaped, with one end forming a snap-fit ​​structure with the socket, and the other end extending into the wiring cavity and having a threaded hole.

[0009] In the above technical solution, the snap-fit ​​structure further includes: The hook is connected to the panel fixing piece, and a relief groove is formed between the hook and the panel fixing piece for bending. The inner wall of the socket has a locking hole for engaging with the hook.

[0010] In the above technical solution, further: The box body has a first round hole on the side of the boss and a second round hole on the other side. A circular baffle is installed in both the first and second round holes, and a first connecting strip is provided between the circular baffle and the inner wall of the first and second round holes.

[0011] In the above technical solution, further: Both the first and second circular holes extend radially upwards to both sides to form extension holes, and an arc-shaped baffle is installed inside the extension hole. A second connecting strip is provided between the arc-shaped baffle and the inner wall of the extension hole.

[0012] In the above technical solution, further: The extended holes formed by the first circular hole are located on the upper and lower sides of the first circular hole; The extended holes formed by the second circular hole are located on the left and right sides of the second circular hole.

[0013] The beneficial effects of this utility model are as follows: 1. By setting splicing plates on the bottom surface of the box and fixing them with connecting posts and connecting holes, the spacing and angle between multiple boxes are limited, allowing multiple boxes to be installed as a whole. This facilitates the installation of multiple boxes and brings a neat and uniform effect, thus effectively ensuring the aesthetics of multiple boxes installed side by side and avoiding any impact on the subsequent installation of switch panels and socket panels.

[0014] 2. The grooves on the bottom of the box facilitate the embedded connection of the splicing panels. At the same time, the connecting posts are flush with the bottom of the box, so that when installing individual boxes, the connecting posts can provide support and ensure the stability of the installation of individual boxes.

[0015] 3. By using a snap-fit ​​connection for the panel fixing pieces, the ease of installation and the stability of the connection after installation can be effectively improved.

[0016] 4. The opening of the first round hole, the second round hole, and the extension hole facilitates the insertion of the wire into the wiring cavity. The extension hole and the arc-shaped baffle allow for the expansion of the wire insertion area by knocking off the arc-shaped baffle. This enables adjustment when there is a deviation in the groove on the wall used to install the junction box and wire, reducing the need for changes in the position of the junction box and minimizing deviations from the preset installation position, thus avoiding affecting the aesthetics of the entire wall surface.

[0018] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0019] Example 1: This embodiment provides a modular junction box, including: The box body 1 has a wiring cavity 2 for wiring; The splicing panel 3 is installed at the bottom of the box 1 and is used for connection and fixation between two adjacent boxes 1; Among them, the bottom surface of the box body 1 is provided with multiple connecting posts 4, and the splicing plate 3 is provided with multiple connecting holes 5 that are fixedly inserted into the connecting posts 4; Meanwhile, the box body 1 and the connecting column 4 are integrally injection molded, and the box body 1 is made of plastic.

[0020] As can be seen from this embodiment, by setting the splicing plate 3 on the bottom surface of the box 1 and fixing it by connecting post 4 and connecting hole 5, the spacing and angle between multiple boxes 1 are limited, so that multiple boxes 1 can be installed as a whole, which facilitates the installation of multiple boxes 1 and brings a neat and uniform effect, thereby effectively ensuring the aesthetics of multiple boxes 1 after side-by-side installation and avoiding the impact on the subsequent installation of switch panels and socket panels. Furthermore, the connecting post 4 is set on the box body 1, and the connecting hole 5 is opened on the splicing plate 3, which facilitates the manufacturing of the box body 1 and the splicing plate 3. In the process of packaging and transportation of the box body 1 and the splicing plate 3, the connecting post 4 is located on the box body 1, which is less likely to break than when it is located on the splicing plate 3, thus ensuring product quality.

[0021] Example 2: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The bottom surface of the box body 1 has a groove 6 that is compatible with the splicing plate 3, and the connecting post 4 is installed on the inner wall of the groove 6; Among them, the connecting column 4 is flush with the bottom surface of the box 1.

[0022] As can be seen from this embodiment, the groove 6 opened on the bottom surface of the box 1 facilitates the embedded connection of the splicing plate 3. At the same time, the connecting post 4 is flush with the bottom surface of the box 1, so that when the box 1 is installed individually, the connecting post 4 can play a supporting role, which can ensure the stability of the installation of a single box 1.

[0023] Example 3: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes: The boss 7 is installed on the side of the box 1, and the bosses 7 of two adjacent boxes 1 abut against each other; Among them, the surface of the boss 7 away from the box body 1 is flat; Meanwhile, the boss 7 and the box body 1 are integrally injection molded.

[0024] As can be seen from this embodiment, the protrusion 7 ensures that after the two adjacent boxes 1 are connected and fixed by the splicing plate 3, the other side of the two adjacent boxes 1 can abut against each other, improving the stability when holding the box. The protrusion 7 can also identify the installation direction of the junction box.

[0025] Example 4: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The boss 7 has a socket 8, and the socket 8 is connected to a panel fixing piece 9; Among them, the panel fixing piece 9 is L-shaped, and one end forms a snap-fit ​​structure with the socket 8, while the other end extends into the wiring cavity 2 and is provided with a threaded hole 10. Meanwhile, the panel fixing piece 9 can be made of metal.

[0026] As can be seen from this embodiment, by opening a socket 8 on the boss 7 and installing the panel fixing piece 9 into the socket 8 through a snap-fit ​​structure, the convenience of installing the panel fixing piece 9 and the connection stability after installation can be effectively improved. In addition, the boss 7 can also improve the structural strength at the socket 8. The panel mounting plate 9 is L-shaped and has threaded holes 10, which facilitates the connection and fixing of the switch panel or socket panel to the junction box by bolts.

[0027] Example 5: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a snap-fit ​​structure: The hook 11 is connected to the panel fixing piece 9, and a relief groove 12 is formed between the hook 11 and the panel fixing piece 9 for bending. The inner wall of the socket 8 is provided with a locking hole 13 that engages with the hook 11.

[0028] As can be seen from this embodiment, by setting the hook 11 on the panel fixing piece 9, the structural strength of the hook 11 can be effectively improved based on the metal material of the panel fixing piece 9, and the breakage situation can be avoided. At the same time, the relief groove 12 facilitates the bending of the hook 11, so that it can be removed in the locking hole 13, which facilitates the disassembly of the panel fixing piece 9. Meanwhile, the design of the hook 11 and the hole 13 makes it easy to directly press the panel fixing piece 9 into the insertion hole 8, which is highly convenient to operate, simple in structure, easy to manufacture and low in cost.

[0029] Example 6: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The box body 1 has a first round hole 14 on the side of the boss 7 and a second round hole 15 on the other side. A round baffle 16 is installed in both the first round hole 14 and the second round hole 15, and a first connecting strip 17 is provided between the round baffle 16 and the inner wall of the first round hole 14 and the second round hole 15. The first connecting strip 17 and the circular baffle 16 are integrated with the box body 1.

[0030] As can be seen from this embodiment, the opening of the first round hole 14 and the second round hole 15 facilitates the installation and connection of wires through the wiring cavity 2 of the junction box. The round baffle 16 can block some of the first round hole 14 and the second round hole 15 when they are not in use, preventing excessive cement from flowing into the wiring cavity 2 when filling with cement. The first connecting strip 17 can fix the round baffle 16 on the one hand, and can be easily cut or knocked off when the first round hole 14 and the second round hole 15 need to be used for wires, thus improving convenience.

[0031] Example 7: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features: Both the first circular hole 14 and the second circular hole 15 extend radially upward to both sides to form an extension hole 18, and an arc-shaped baffle 19 is installed in the extension hole 18, and a second connecting strip 20 is provided between the arc-shaped baffle 19 and the inner wall of the extension hole 18. The second connecting strip 20 and the arc-shaped baffle 19 are integrated with the box body 1.

[0032] As can be seen from this embodiment, by opening the extension hole 18 and setting the arc-shaped baffle 19 in the extension hole 18, the position selection of the wire entering the wiring cavity 2 can be expanded. When the groove on the wall used to install the junction box and the wire deviates, the position of the junction box is reduced, the installation position of the junction box deviates too much from the preset position, and the aesthetics of the entire wall are avoided. The arc-shaped baffle 19 is designed to cover some of the extension holes 18 when they are not in use, so as to prevent too much cement from flowing into the wiring cavity 2 when filling with cement. The second connecting strip 20 can fix the arc-shaped baffle 19, and can also be easily cut or knocked off when the position of the wire through the extension hole 18 needs to be adjusted, thus improving convenience.

[0033] Example 8: This embodiment provides a modular junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The extension hole 18 formed by the first circular hole 14 is located on the upper and lower sides of the first circular hole 14. The extension holes 18 formed by the second circular hole 15 are located on the left and right sides of the second circular hole 15.

[0034] As can be seen from this embodiment, since the second round hole 15, that is, the hole on the upper and lower sides of the wall after the junction box is installed, is usually designed for the wires to pass through the wire grooves cut in the wall, the extension hole 18 is located on the left and right sides of the second round hole 15, which can effectively reduce the position change of the junction box due to the error of the wall wire groove opening. The first round hole 14, which is the hole on the left and right sides of the wall after the junction box is installed, is usually designed for the wires to pass through between two adjacent junction boxes. For example, if multiple junction boxes are set up side by side and belong to the same main wire, the wires can pass through the round holes on the left and right sides of the junction box, thereby reducing the need to chisel the wire groove in the wall. Therefore, the extension hole 18 is located on the upper and lower sides of the first round hole 14, which allows the horizontally passing wires and the vertically passing wires to be arranged in a layered and staggered manner, thereby effectively improving the convenience and aesthetics of wiring and making it easy to distinguish. The junction box structure of this application is simple and consists of only three components: box body 1, splicing plate 3, and panel fixing piece 9. It is easy to operate and can effectively solve the problem of deviation in the spacing and angle between adjacent junction boxes when multiple junction boxes are installed side by side, which affects the aesthetics of the subsequent switch panel and socket panel after installation.

[0035] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
