[0002] Photovoltaic cable is a specialized cable used in solar photovoltaic power generation systems. Waterproofing the connectors of photovoltaic cables can prevent moisture from entering the circuit, causing changes in electrical parameters such as resistance and capacitance at the connector, affecting the efficiency and stability of power transmission. Using a waterproof protective box at the connector can provide maximum protection.

[0003] In the process of realizing this application, the inventor discovered that the existing technology has the following problems: the traditional waterproof connector protection box generally includes a box body, an interface, a box cover, fixing parts and other structures, and lacks a mechanism for fixing the interface. Over time, the interface of the cable may become loose, resulting in poor circuit. At the same time, there is a lack of a mechanism that can be easily fixed on the photovoltaic panel bracket, resulting in the box body can only be placed on the ground or on other objects, reducing the adaptability of the box body itself to the usage scenario.

[0004] Therefore, those skilled in the art provide a waterproof connector protection box to solve the problems raised in the above background technology. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, the utility model provides an embodiment: a joint waterproof protection box, including a box body 1, the top surface of the box body 1 is threadedly connected with a clamping mechanism 2 near the center, the clamping mechanism 2 includes a No. 1 screw 201, the outer wall of the No. 1 screw 201 is threadedly connected to the contact surface of the box body 1, the bottom end surface of the No. 1 screw 201 is fixedly connected to a moving block 202, and the two sides of the outer wall of the moving block 202 are fixedly connected to sliding rods 204, two No. 1 grooves 203 are provided on the upper half ends of the inner walls of the box body 1 near the center line, a bottom plate 205 is fixedly connected to the center of the bottom end surface of the box body 1, a fixing column 206 is fixedly connected to the top surface of the bottom plate 205, and a fixing block 207 is fixedly connected to the top surface of the fixing column 206; the box The rear end face of the body 1 is provided with a fixing mechanism 3, which includes two clamping blocks 303, the inner walls of the two clamping blocks 303 are rotatably connected to the double-headed screws 302, the outer walls of the double-headed screws 302 are threadedly connected to two sliders 308, the outer walls of the two sliders 308 are fixedly connected to large clips 306, the two large clips 306 are fixedly connected to the ends away from the box body 1 with small clips 307, the inner walls of the two small clips 307 are fixedly provided with fixing bolts 309, the rear end face of the box body 1 is located below the double-headed screws 302 and is fixedly connected to two fixing rods 304, the two fixing rods 304 are fixedly connected to the tops away from the box body 1 with support rods 305, and the two support rods 305 are rotatably connected to the two large clips 306.

[0024] Specifically, hold the No. 1 screw 201 and rotate it. The No. 1 screw 201 is threadedly connected to the top surface of the box body 1, so it pushes the moving block 202 to move downward. Because the sliding rods 204 on both sides of the moving block 202 are restricted by the two No. 1 grooves 203 and cannot rotate, they can only move. The moving block 202 is used in conjunction with the fixed block 207 at the bottom of the cable 4 to clamp and fix the interface of the cable 4 to prevent it from loosening.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ; The two sliding rods 204 are slidably arranged in the two No. 1 grooves 203, the two fixing bolts 309 pass through the top of the two large clips 306, and the other end is cut on the inner wall of the two small clips 307. The rear end face of the box body 1 is fixedly connected to the two blocks 303, and the rear end face of the box body 1 is slidably connected to the two sliders 308. Cable ports 7 are opened on both sides of the box body 1, and cables 4 are movably arranged on the inner walls of the two cable ports 7. A hinge 5 is fixedly connected to one side of the front end face of the box body 1, and a door panel 6 is fixedly connected to the outer wall of the hinge 5. The rear end face of the door panel 6 is convex, and the door panel 6 is movably arranged inside the box body 1. A handle 301 is fixedly connected to the outer wall of the double-headed screw 302 near the hinge 5, and two support rods 305 provide support for the two large clips 306.

[0026] Specifically, hold the handle 301 and rotate it to drive the double-headed screw 302 to rotate. The double-headed screw 302 is threadedly connected to the two sliders 308, so the two sliders 308 move outward along the rear end of the box body 1, driving the two large clamps 306 to move outward. Because the two large clamps 306 are supported by the support rod 305 at the bottom, the rear ends of the two large clamps 306 move inward, driving the two small clamps 307 to move inward to clamp the support rod of the photovoltaic cable.

[0027] Working principle: First, insert the cable 4 from the cable openings 7 on both sides of the box 1, open the door panel 6, and rotate the door panel 6 along the hinge 5. Connect the two cables 4 inside the box 1 and place them on top of the fixed block 207. At this time, hold the No. 1 screw 201 and rotate it. The interface between the No. 1 screw 201 and the box 1 is threaded. The sliding rods 204 on both sides of the moving block 202 are restricted by the No. 1 grooves 203 on both sides of the box 1, causing the No. 1 screw 201 to rotate. The moving block 202 moves downward and cannot rotate until it fixes the interface of the cable 4 together with the fixed block 207 at the bottom and stops moving. The bottom plate 205 and the fixed column 206 provide support and fixation for the fixed block 207.

[0028] Secondly, hold the handle 301 and rotate it. The rotation of the handle 301 drives the double-headed screw 302 at the bottom to rotate, and the double-headed screw 302 rotates along the inner walls of the two blocks 303. Because the two sliders 308 are threadedly connected to the double-headed screw 302, and the two sliders 308 are in contact with the rear end surface of the box body 1 and are slidably connected, the two sliders 308 are restricted by the rear end surface of the box body 1 and move along the outer wall of the double-headed screw 302, driving the front ends of the two large clips 306 to move outward. At this time, the two large clips 306 are supported by the two support rods 305 at the bottom, and the rear ends of the two large clips 306 move inward. The movement of the two large clips 306 inward drives the two small clips 307 to move inward. The two fixing bolts 309 are used to fix the two large clips 306 and the two small clips 307. The outer walls of the opposite sides of the two small clips 307 are both concave and convex surfaces, which can provide greater friction for clamping and fixation.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
