Technical Field
[0001] This utility model relates to the field of junction boxes, and more particularly to a splicing junction box. Background Technology
[0002] A junction box is an electrical device used to protect, connect, and distribute wires. It is usually made of flame-retardant plastic or metal and has internal terminals or connectors to facilitate the safe and reliable connection or branching of wires. It is widely used in construction, industry, photovoltaic systems and other fields.
[0003] When installing junction boxes, the two templates of the junction box are usually connected by multiple bolts, which is a complicated and inefficient process. At the same time, when connecting the wires to the connector slot, the wires are removed from the slot, inserted into the slot, and then the bolts are driven in, which is inconvenient. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular junction box that improves the efficiency of device installation and wiring.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A modular junction box, comprising:
[0007] A lower splicing box for bottom support, with an upper splicing box attached to its top. The upper splicing box has through slots on both sides of its top. Multiple upper arc-shaped covers are fixedly connected to the sides of the upper splicing box. A lower arc-shaped cover is fixedly connected to the sides of the lower splicing box. A connector is fixedly connected inside the lower splicing box. Fixing seats are fixedly connected to both sides of the lower splicing box, and fixing slots are provided on both sides. Each fixing seat has a flip-fixing component installed inside to facilitate splicing and installation.
[0008] Multiple wiring slots are provided on the side of the connector. Each wiring slot has a copper post fixedly connected to its bottom. A pressure wiring assembly is installed inside the wiring slot to facilitate wiring.
[0009] Furthermore, the pressure-down wiring assembly includes a pressure-down stabilizing plate that slides inside the wiring slot, a pressure-down sleeve that is fixedly connected to the top of the pressure-down stabilizing plate, a pressure-down stud that is rotatably connected to the top of the connector inside the wiring slot, and the inner thread of the pressure-down sleeve that is threaded to the outside of the pressure-down stud.
[0010] Furthermore, the flip-fixing assembly includes a flip-fixing frame located inside the fixing base, with positioning insertion posts inserted inside the flip-fixing frame. The outer sides of the positioning insertion posts penetrate the interior of the insertion slot, and the lower outer sides of the positioning insertion posts are threadedly connected to the interior of the fixing slot.
[0011] Furthermore, each of the positioning insertion posts is fixedly connected with a mounting cap to facilitate disassembly and assembly.
[0012] Furthermore, the top of the upper splicing box is provided with multiple slots, each of which corresponds to an interface on the top of the connector.
[0013] Furthermore, each of the downward-pressing studs is fixedly connected to a terminal cap, and the outer surface of the terminal cap is respectively inserted into the circular groove of the upper splicing box.
[0014] Furthermore, a transfer copper sheet is fixedly connected to the lower outer side of the wiring copper post to increase the contact area of the copper wire.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by flipping the fixed frame inward, the inclined surface of the fixed frame contacts the top of the upper splicing box. After the fixed frame is fully flipped, the upper splicing box and the lower splicing box are combined. At this time, the positioning insertion post is inserted, and the mounting cap is rotated and screwed into the inside of the fixing groove to complete the splicing of the junction box, thereby improving the efficiency of device installation.
[0017] 2. In this utility model, the wire at the connection point is bent and looped around the outside of the copper post. At this time, the connection cap is rotated, thereby rotating the pressure stud. The pressure sleeve is pressed down, thereby squeezing the wire by the pressure stabilizing plate. The device makes it easier to fix the wire and improves the efficiency of wiring. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-3 This utility model provides an embodiment of a modular junction box, comprising: a lower junction box 1 for bottom support; an upper junction box 2 attached to the top of the lower junction box 1; through slots 7 on both sides of the top of the upper junction box 2; multiple upper arc covers 13 fixedly connected to the sides of the upper junction box 2; a lower arc cover 14 fixedly connected to the sides of the lower junction box 1; a connector 8 fixedly connected inside the lower junction box 1; fixing seats 6 fixedly connected to both sides of the lower junction box 1; fixing slots 17 on both sides of the lower junction box 1; and connectors 8 installed inside the fixing seats 6. Equipped with a flip-fixing assembly for easy splicing and installation, the flip-fixing assembly includes a flip-fixing frame 4 located inside the fixing base 6, a positioning insertion post 9 inserted inside the flip-fixing frame 4, the outside of the positioning insertion post 9 passing through the inside of the insertion slot 7, the lower side of the outside of the positioning insertion post 9 being threadedly connected to the inside of the fixing slot 17, and an installation cap 3 fixedly connected to the outside of the positioning insertion post 9 for leveraging disassembly and splicing; the top of the upper splicing box 2 has multiple slots 16, which correspond to the interfaces at the top of the connector 8;
[0026] After completing the wiring, align the top of the upper splicing box 2 with the top of the lower splicing box 1. Then, flip the fixing frame 4 inward, so that its outer bevel contacts the top edge of the upper splicing box 2, generating an inward force that presses the upper and lower splicing boxes together. Then, pass the positioning insertion post 9 through the slot and slot 7 of the flip fixing frame 4, and insert its bottom end into the fixing slot 17. Finally, rotate the mounting cap 3 to engage and lock the external thread of the positioning insertion post 9 with the fixing slot 17. This structural design enables the rapid splicing and installation of the junction box, significantly improving installation efficiency.
[0027] Reference Figure 3 and Figure 4 Multiple wiring slots 12 are provided on the side of the connector 8. A wiring copper post 10 is fixedly connected to the bottom of each wiring slot 12. A pressing wiring assembly is installed inside the wiring slot 12 to facilitate wiring. The pressing wiring assembly includes a pressing stabilizing plate 11 that slides inside the wiring slot 12. A pressing sleeve 19 is fixedly connected to the top of the pressing stabilizing plate 11. A pressing stud 15 is rotatably connected to the top of the connector 8 inside the wiring slot 12. The inner side of the pressing sleeve 19 is threaded to the outside of the pressing stud 15. A wiring cap 5 is fixedly connected to the top of each pressing stud 15. The outside of the wiring cap 5 is respectively inserted into the circular groove of the upper splicing box 2. A transmission copper sheet 18 is fixedly connected to the lower side of the wiring copper post 10 to increase the contact area of the copper wire.
[0028] When wiring the device, first bend the wire at an appropriate angle and put it on the copper terminal 10. Rotate the terminal cap 5 to drive the pressing stud 15 to rotate. Its external thread engages with the inner side of the pressing sleeve 19. Due to the limiting effect of the pressing stabilizing plate 11, the pressing sleeve 19 is forced to move down and finally nests and presses against the outer surface of the copper terminal 10. This action makes the wire firmly pressed against the top of the transmission copper plate 18, ensuring the stability of power transmission. This design achieves fast and reliable wiring fixation and significantly improves the efficiency of wiring operations.
[0029] Working principle: When wiring the device, bend the wire at a certain angle at the connection point and loop the wire around the outside of the copper terminal 10. Then rotate the terminal cap 5, thereby rotating the pressing stud 15. The external thread of the pressing stud 15 contacts the inner side of the pressing sleeve 19. Due to the restriction of the pressing stabilizing plate 11, the pressing sleeve 19 moves downward, thereby pressing down the pressing stabilizing plate 11. As it is pressed down, the inner side of the pressing sleeve 19 is nested around the outside of the copper terminal 10, thereby pressing the wire down so that it fits tightly against the top of the transmission copper plate 18, thus ensuring stable power transmission. After completing the wiring, install the device and place the upper splicing box 2. The top of the lower splicing box 1 is attached to the top. At this time, the flip fixing frame 4 is flipped inward. The outer slope of the flip fixing frame 4 contacts the top edge of the upper splicing box 2, thereby exerting a force inward on the flip fixing frame 4, flipping the flip fixing frame 4 so that it restricts the lower splicing box 1 and the upper splicing box 2 to fit together. At this time, the positioning insertion post 9 is passed through the slot of the flip fixing frame 4 and through the inside of the slot opening 7. The bottom end of the positioning insertion post 9 is inserted into the inside of the fixing slot 17, and the mounting cap 3 is rotated so that the external thread of the positioning insertion post 9 contacts the inside of the fixing slot 17, thereby completing the splicing and installation of the junction box.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
