[0002] Junction boxes, as indispensable basic equipment in electrical engineering, have the core function of achieving precise connection, reliable protection, and efficient distribution of wires, making them a key component for ensuring the stable operation of electrical systems. They are widely used in distribution boxes and switchgear in the building sector, automation equipment and control cabinets in industrial settings, and base stations and data centers in the communications industry, covering diverse electrical environments from civil to industrial, and from low voltage to high voltage. Their structural design must be deeply tailored to the needs of different application scenarios. It must ensure the safety of operators and equipment through insulation materials and protection levels, guarantee long-term operational reliability through reasonable wiring space and robust terminal structures, and optimize ease of installation and maintenance through modular layout and convenient opening methods. Thus, they play a pivotal role in complex and ever-changing electrical systems.

[0003] Currently, most existing junction box structures are single-circuit. In scenarios where multiple devices need to be connected, using a single-circuit junction box may lead to messy wiring. Furthermore, when connecting multiple devices or circuits, a single-circuit junction box may cause safety hazards due to overload or short circuit. Therefore, a dual-circuit junction box structure can effectively solve this problem.

[0004] Junction boxes are typically composed of a base, a top cover, glands, and a corresponding number of branch circuits. In traditional junction box structures, the base and top cover are often connected and fixed with screws, which requires the use of corresponding tools to complete the installation, making it very inconvenient and reducing the ease of installation. Utility Model Content

In traditional dual-branch junction box structures, the base and the top cover are often connected and fixed by screws, so installation requires the use of corresponding tools, which is very inconvenient and reduces the ease of installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-branch junction box structure, including a base, a top cover on the top of the base, two glands connected to one end of the base, and a first branch and a second branch connected to one end of the two glands.

[0022] 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.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a dual-branch junction box structure, including a base 1, a top cover 2 on the top of the base 1, two glands 3 connected to one end of the base 1, and a first branch 4 and a second branch 5 connected to one end of the two glands 3.

[0024] It is important to note that the connection points of the base 1 and the two gland heads 3 are made of robust and durable metal. This metal undergoes a special process, resulting in excellent mechanical strength and impact resistance. It can withstand external forces such as collisions and compression that may occur in complex industrial environments, greatly reducing the risk of damage to the connection points due to external forces. The threaded connections at the tail ends of the two gland heads 3 are also made of metal. The high-precision machining of the threads, combined with the high strength of the metal itself, not only ensures the tightness and stability of the connection, preventing loosening under vibration, but also effectively avoids connection failure due to thread wear. Furthermore, the dual-branch junction box of this application exhibits excellent durability and is not easily damaged. Simultaneously, the conductivity and electromagnetic shielding properties of the metal effectively block external electromagnetic interference signals, making the electrical signal transmission within the box more stable and providing excellent shielding, thus ensuring the reliable operation of electrical equipment. In addition, a connector is carefully installed inside the base 1. The connector is made of high-quality conductive material and has good conductivity and contact stability. It can quickly and accurately realize the circuit connection, simplify the wiring operation process, improve the efficiency of electrical installation and maintenance, and its compact structural design makes full use of the internal space of the base 1, making the overall layout of the junction box more reasonable and compact.

[0025] It is also worth noting that the base 1, top cover 2, gland 3, first branch 4, and second branch 5 can be combined to form a dual-branch junction box. Therefore, compared with the single-branch junction box in the prior art, the tube block in this application, as one of the core components of the dual-branch connection, is made of a high-strength metal frame and weather-resistant composite material, and its interior is equipped with precisely matched dual-channel wiring grooves. These wiring grooves not only provide good fixation for cables or optical cables, but also, through optimized curvature and spacing design, prevent excessive stress on the cables during bending, thus preventing signal attenuation and current loss.

[0026] The connector protective sleeve features a three-layer composite structure. The outer layer is made of high-toughness polyurethane material, offering excellent impact and abrasion resistance. The middle layer is a flexible buffer layer that absorbs external vibrations and impacts. The inner layer is an anti-static coating that effectively prevents static electricity from interfering with signal transmission. This protective sleeve uses a snap-on quick-installation structure to easily cover cable or fiber optic connectors, providing comprehensive protection.

[0027] Finally, in terms of signal and current transmission, the internal connector adopts a design that combines gold-plated contacts with flexible metal clips. The gold-plated contacts can effectively reduce contact resistance, improve conductivity, and reduce signal loss during transmission; the flexible metal clips can automatically adjust the clamping force according to the cable specifications to ensure the tightness and stability of the connection.

[0028] The outer wall of the base 1 is connected to the mounting base 6. The mounting base 6 is equipped with a spring 7. The end of the spring 7 is connected to a movable block 8. One end of the movable block 8 is connected to a limit pin 9. The outer wall of the movable block 8 is connected to a toggle block 10. The bottom of the top cover 2 is connected to an insert block 11. One end of the insert block 11 has a limit slot 12.

[0029] Preferably, the size of the limiting slot 12 is adapted to one end of the limiting pin 9, the outer wall of the mounting base 6 has an opening, and the toggle block 10 can extend to the outside through the opening of the outer wall of the mounting base 6. The upper cover 2 can form an elastic locking structure with the base 1 through the mounting base 6, spring 7, movable block 8, limiting pin 9, toggle block 10, insert block 11, and limiting slot 12.

[0030] In practical use, by moving the movable block 8 with the toggle 10, the limiting pin 9 is retracted. Then, the two inserts 11 at the bottom of the top cover 2 are inserted into the slots 14 respectively. At this time, the top cover 2 will close with the base 1. Then, by releasing the toggle 10, the limiting pin 9 can be popped out and inserted into the limiting slot 12 under the action of the spring 7, so as to more conveniently realize the connection and fixation between the base 1 and the top cover 2.

[0031] Preferably, the end of the mounting base 6 is connected to a connecting block 13, and the top of the connecting block 13 is provided with a slot 14. One end of the insert 11 can be inserted into the interior of the connecting block 13 through the slot 14, and one end of the limiting pin 9 extends into the interior of the slot 14.

[0032] In practical use, by using the toggle 10 to move the movable block 8, the limiting pin 9 is retracted, allowing one end of the limiting pin 9 to disengage from the limiting slot 12. Then, by pulling the top cover 2 upward, the insert 11 is disengaged from the slot 14, thus completing the disassembly and making it easier to remove the top cover 2.

[0033] Working principle: First, when installing the top cover 2, the movable block 8 is moved by the toggle 10 to retract the limiting pin 9. Then, the two inserts 11 at the bottom of the top cover 2 are inserted into the slots 14 respectively. At this time, the top cover 2 will close with the base 1. Then, by releasing the toggle 10, the limiting pin 9 can be popped out by the spring 7 and inserted into the limiting slot 12, so that the connection and fixation between the base 1 and the top cover 2 can be more conveniently achieved. Furthermore, by moving the movable block 8 by the toggle 10 to retract the limiting pin 9, one end of the limiting pin 9 can be disengaged from the limiting slot 12. Then, the top cover 2 is pulled upward to disengage the inserts 11 from the slots 14 to complete the disassembly, thus making the top cover 2 easier to remove.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
