Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a waterproof switch box. Background Technology

[0002] The term "switch" is defined as turning on and off. It refers to an electronic component that can open a circuit, interrupt current, or divert it to another circuit. The most common switches are mechanical devices operated by humans, containing one or more electronic contacts. A "closed" contact indicates that the electronic contacts are conducting, allowing current to flow. An "open" switch indicates that the electronic contacts are not conducting, forming an open circuit and preventing current from flowing. However, considering the complex environments in which switches are used, such as outdoor environments, switches are susceptible to damage from rain. Water entering the switch and contacting the circuit can cause a short circuit, posing a significant safety hazard.

[0003] Waterproof switch boxes are typically used to prevent water from entering the internal circuitry. A switch box usually consists of a box body and a cover. However, existing switch boxes still have the problem of the cover not closing tightly. The cover can be blown open in the wind, thus failing to provide waterproofing. The purpose of this utility model is to propose a corresponding solution to the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a waterproof switch box.

[0026] like Figures 1 to 7 As shown, this is an embodiment of the present invention: a waterproof switch box, including a box body 1 and a box cover 2. The box body 1 has an internal mounting cavity 3 for installing a switch. The box cover 2 is hinged to the box body 1. A rotating groove 4 is provided on the side of the box cover 2 corresponding to the hinge. A torsion spring 5 for driving the box cover 2 to close toward the box body 1 is installed in the rotating groove 4. A first insertion hole 6 is provided on one side of the rotating groove 4. The box body 1 has a second insertion hole 7. One end of the torsion spring 5 is inserted into the first insertion hole 6 and the other end is inserted into the second insertion hole 7. A pressing block 8 is also protruding on the side of the box body 1 corresponding to the second insertion hole 7 for the torsion spring 5 to abut against. The torsion spring 5 is compressed between the pressing block 8 and the inner wall of the rotating groove 4.

[0027] The beneficial effects of this design are as follows: This utility model uses a torsion spring to help the cover maintain a tight closure with the box body, enabling the switch box to adapt to harsh outdoor environments, preventing the cover from being blown open by the wind, maintaining good waterproof performance, and the torsion spring is compressed between the pressing block and the inner wall of the rotating groove. Under appropriate tightness, the torsion spring can provide sufficient torque and rotational force, and the torsion spring is not easy to loosen from the rotating groove, ensuring a firm installation.

[0028] Furthermore, the rotating groove 4 also extends to include a sleeve 9 that surrounds the outside of the torsion spring 5.

[0029] The beneficial effects of this design are as follows: the sleeve further protects the torsion spring and prevents it from popping out.

[0030] Furthermore, the cover 2 is provided with at least one hinge shaft 10, and the box body 1 is detachably connected with at least one hinge seat 11 adapted to the hinge shaft 10.

[0031] The beneficial effects of this configuration are as follows: In this embodiment, there are two hinge shafts and two corresponding hinge seats. Each hinge shaft is hinged to a corresponding hinge seat, and the two hinge shafts are distributed on both sides of the torsion spring, which restricts and reinforces the connection between the lid and the box body, preventing the lid from detaching from the box body from the side. It also limits the torsion spring installed in the middle, maintaining the compression of the torsion spring. The hinge seats are detachably connected by bolts, which facilitates disassembly, assembly, and fastening.

[0032] Furthermore, the cover 2 is provided with an observation window 12 that connects the outside world to the installation cavity 3, and the observation window 12 is embedded with a transparent waterproof component 13 for isolating the outside world from the installation cavity 3.

[0033] The beneficial effects of this design are as follows: an observation window is opened on the cover and a transparent waterproof component is installed, which makes it easy to observe the opening and closing status of the switch inside the installation cavity. In this embodiment, the transparent waterproof component is made of transparent silicone. Silicone has deformable properties, so the switch can be opened and closed directly by pressing the transparent waterproof component. The switch can be operated without opening the cover, thus preventing water from entering the installation cavity when the cover is opened.

[0034] In a further configuration, the transparent waterproof component 13 has a water baffle 14 extending outward from one end near the mounting cavity 3. The water baffle 14 fits against the inner wall of the cover 2, and the water baffle 14 has a water baffle strip 15 protruding from it. The inner wall of the cover 2 has a water baffle groove 16 that matches the water baffle strip 15.

[0035] The beneficial effects of this design are as follows: through the sealing cooperation between the water-blocking strip of the baffle plate and the water-blocking groove, the baffle plate forms the first seal and the water-blocking strip forms the second seal, which greatly improves the sealing and waterproofing performance.

[0036] Furthermore, the end face of the baffle plate 14 near the mounting cavity 3 is recessed with a sealing ring groove 17, and the mounting cavity 3 has a protruding sealing ring platform 18 that matches the sealing ring groove 17.

[0037] The beneficial effects of this design are as follows: the sealing ring groove and the sealing ring platform cooperate in a sealing manner, which improves the sealing performance between the lid and the box body when they are closed.

[0038] Furthermore, the transparent waterproof component 13 extends outward toward the observation window 12 with a waterproof protrusion 19, the end face of the waterproof protrusion 19 being arc-shaped, and the inner wall of the transparent waterproof component 13 near the mounting cavity 3 also has several oblique ribs 20 protruding.

[0039] The beneficial effects of this design are as follows: the curved waterproof convex surface can divert water droplets from the surface, reducing the accumulation of water droplets and eliminating the possibility of leakage; the inclined ribs provide support, allowing the waterproof convex surface to maintain its curved shape.

[0040] In a further configuration, the transparent waterproof component 13 has a feeding end 21 extending from the side near the rotating groove 4. The end of the feeding end 21 is adapted to the rotating groove 4 and abuts against the inner wall of the rotating groove 4. The box cover 2 is provided with a feeding groove 22 for the feeding end 21 to be inserted.

[0041] The advantages of this design are as follows: the fit between the feed end and the feed trough facilitates the processing and installation of transparent and waterproof components.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
