Technical Field

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

[0002] A junction box is an electrical device used to protect and connect wires and cables.

[0003] Existing technologies generally employ screw-sealed waterproof junction boxes, press-on or rotary snap-on waterproof junction boxes, and hinged waterproof junction boxes with the cover integrated with the enclosure. Existing junction boxes have the following drawbacks: Screw-sealed waterproof junction boxes require waterproofing treatment at the bolt fixing points using gaskets or sealant; opening and closing operations are relatively complex and require tools; during operation, the cover and bolts are at risk of falling off, making them unsuitable for installation near edges, at heights, or in other areas with a risk of falling; frequent opening and closing also carries the risk of bolt stripping. Press-on or rotary snap-on waterproof junction boxes often suffer from poor sealing due to prolonged opening and closing. Hinged waterproof junction boxes with an integrated enclosure are prone to dirt accumulation and jamming on the hinges, resulting in the cover often being in a partially open state; their waterproof performance is also generally poor, and the sealing strip requires additional maintenance.

[0004] Therefore, the structure of the junction box needs to be optimized to achieve a junction box with better waterproofing and easier operation. Utility Model Content

[0005] In view of the technical problems existing in the background art, the present invention provides a small outdoor waterproof junction box, which is stable and firm after fixing, and has strong waterproof performance and is easy to operate.

[0013] Preferably, the junction box body and the box cover are respectively provided with a female and a male fastener. When the box cover is closed, the male fastener undergoes elastic deformation and engages with the female fastener.

[0014] This utility model has the following advantages and beneficial effects: The junction box of this utility model has a sealing strip on the contact surface between the box body and the cover, and a water-repellent rolled edge at the opening of the box, which can effectively prevent rainwater or moisture from seeping into the interior of the junction box, improve the waterproof performance of the junction box, and is suitable for harsh outdoor environments such as high humidity, rain, and water accumulation. The cable inlet of this utility model has good sealing performance and mechanical strength, and can simultaneously connect multiple cables while ensuring a sealing effect, thus meeting the wiring needs of multiple devices or multiple signal channels. The support legs of this utility model are fixed to the target installation position by bolts, which makes it easy for the junction box to be stably installed on the wall, tower or other irregular installation surface. The support legs can adopt a flexible U-shaped groove design to adapt to the installation surface of different thicknesses and shapes, thereby improving versatility and installation convenience. The wiring fixing device of this utility model can effectively constrain the position of the wiring wires, thereby improving wiring safety and internal space utilization, and also facilitating later maintenance and troubleshooting. This utility model is equipped with a male buckle and a female seat structure. When the lid is closed, the buckle automatically locks to prevent the lid from being opened accidentally, while also enhancing waterproof and dustproof performance and improving the overall safety level.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1 This embodiment provides a small outdoor waterproof junction box, including a sealing strip, a hydrophobic rolled edge, a junction box body, a box cover, multiple support legs 103, and an internal wiring fixing device; Multiple cable inlets 104 are provided on the top of the junction box body. The cover is rotatably connected to the junction box body. A sealing strip is provided on the contact surface between the cover and the junction box body. A water-repellent rolled edge is provided at the opening of the junction box body. Multiple support legs 103 are installed on the junction box body. The support legs 103 are fixed to the target installation position of the junction box body by bolts. An internal wiring fixing device is installed inside the junction box. The internal wiring fixing device includes a horizontally arranged guide rail device for wiring and a suction cup fixing block 102 for fixing wiring and cable routing.

[0018] Typically, the junction box has a rectangular structure with multiple cable inlets 104 on its upper surface. Each cable inlet 104 has an independent locking and sealing structure, accommodating round cables of different diameters. The opening edges of the junction box can be equipped with hydrophobic rolled edges to guide external water droplets to slide off under gravity, effectively preventing water from flowing back into the box.

[0019] In a preferred embodiment, the cover is rotatably connected to the junction box body via a rotating shaft located at the bottom of the junction box body. The cover can be opened at a relatively large angle due to the rotating shaft. Because a closed-type sealing strip is provided on the contact surface between the cover and the box body, and the sealing strip is typically made of silicone rubber, it provides a good sealing effect and a high level of protection when closed.

[0020] In this embodiment, the support leg 103 is a U-shaped groove support leg 103 made of elastic material. The U-shaped groove design allows for flexible and asymmetrical installation of the junction box. The support leg 103 has a certain degree of elasticity, allowing installation on curved walls or columns. The elastic material also ensures good fixation of the junction box in vibration environments, preventing it from loosening. With this support leg 103 configuration, each support leg 103 is fixed to the target mounting surface, such as a pole, wall, or photovoltaic support beam, using bolts. The elastic support leg 103 has shock absorption and corrosion resistance properties, making it suitable for various complex outdoor environments such as high temperature and high humidity.

[0021] On the other hand, the guide rail device includes a guide rail body 101 and a plurality of spring terminals 106, which are mounted on the guide rail body 101. Specifically, there are 12 spring terminals 106 of PT2.5 specification, while the cable inlets 104 use M8 type gland connectors. There are also 4 cable inlets 104. The horizontally arranged guide rail device is used to achieve quick crimp connections. Suction cup-type fixing blocks are used to magnetically attach and fix the arranged cable bundles, preventing cable shaking and detachment, improving wiring stability and internal wiring neatness.

[0022] Finally, the junction box body and the box cover are respectively provided with a female and a male terminal of the latch 107. When the box cover is closed, the male terminal of the latch 107 elastically deforms and snaps into the female terminal. This structure can achieve a double-sealed protective structure. Based on the way the box is opened by rotating the latch 107, and with the rotation axis of the box cover located on the lower side of the junction box, while the latch 107 can be designed on the top of the box, the inspection and maintenance of the wiring inside the box is simple in environments with installation near edges or at heights, and there is no risk of tools or materials falling.

[0023] In summary, the solution presented in this embodiment offers several advantages. First, it provides excellent fixation even on uneven surfaces or in vibrating environments. Second, it is simple to operate and easy to maintain. The flexible metal clips 107 allow for easy opening and closing, have strong resistance to metal fatigue, and are not easily broken. No tools are required to open the box, eliminating concerns about the cover, tools, and fasteners falling off in special installation environments such as near edges or at heights. Finally, the box opening has a hydrophobic and waterproof structure, providing excellent waterproofing even in rainy conditions. Therefore, after wiring and installation using this waterproof junction box, subsequent inspection and maintenance require no tools, resulting in low maintenance costs and excellent waterproofing.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
