Description

Technical Field

[0001] This utility model relates to the technical field of solar lamps, and in particular to an improved interface device for wiring solar lamps. Background Technology

[0002] Solar lights are a new type of lighting equipment that uses solar energy as its core energy source and achieves the generation, storage, and utilization of electrical energy through photovoltaic conversion technology, thereby providing power for lighting loads. During the use of the lights, various wires are needed to connect the solar panels and the light panels to ensure stable power transmission. However, being exposed to the elements makes them susceptible to environmental factors such as rainwater erosion and dust accumulation, which can affect the lifespan and transmission stability of the wires. Therefore, interface devices are used to connect the wires between the solar panels and the light panels.

[0003] Currently, traditional interface devices must strictly adhere to specifications such as positive and negative polarity matching and voltage compatibility when connecting components. Poor contact can lead to direct burnout of the controller or lighting fixture, or even damage to the battery due to overcharging or over-discharging. Therefore, operators need high levels of professional knowledge and operational skills to ensure the correct installation and use of the interface device. However, in actual operation, due to human or environmental factors, it is still difficult to completely avoid poor contact problems. For example, vibration interference in the outdoor environment (such as road traffic or wind) may cause the wiring terminals to loosen, or dust and insects may enter the connector, affecting contact performance. This not only increases the failure rate of the lighting fixture but may also pose safety hazards. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose an improved interface device for wiring solar lamps. By using the fixing posts of the protective mechanism to fix wires of different specifications in a classified manner, and cooperating with the locking component to achieve flexible opening and closing and stable locking of the cover plate, it can prevent dust and insects from entering the wiring terminal area and avoid loosening problems caused by vibration. It can effectively solve the wiring hazards and poor contact problems existing in traditional interface devices.

[0006] To achieve the above objectives, the first aspect of this utility model proposes an improved interface device for wiring solar lamps, comprising: a junction box, a lamp, a wiring port, a connecting rod, and a protective mechanism. The lamp is installed outside the junction box, and the wiring port is provided on the outer wall of the lamp. The connecting rod is connected to one end of the lamp with the wiring port. The protective mechanism is located inside the junction box and includes a fixing plate, a terminal block, a fixing post, a connecting plate, a first rotating shaft, a cover plate, and a locking assembly.

[0007] In addition, the improved solar lamp wiring interface device proposed above according to this utility model may also have the following additional technical features: Specifically, the locking assembly includes a bolt, a paddle, a fixing block, a locking block, and a spring. The bolt is fixed to the outer wall of the cover plate on the side near the fixing plate, the paddle is sleeved on the outer wall of the bolt, the fixing block is fixed inside the fixing post, the locking block is slidably connected inside the fixing block, and the spring is sleeved on the outside of the locking block.

[0010] Specifically, a washer is fitted on the outer wall of the bolt, and the outer wall of the washer is in contact with the outer wall of the rotating block.

[0011] Specifically, a pad is fitted and fixed to the inner wall of the fastener.

[0012] Compared with existing technologies, this utility model has the following advantages: The improved solar lamp wiring interface device of this utility model, through the classified design of the fixing posts in the protective mechanism, can accurately fix wires of different specifications, effectively avoiding poor contact problems caused by wire mismatch.

[0016] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] An improved interface device for wiring solar lamps according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0018] like Figures 1-7 As shown, an improved solar lamp wiring interface device according to an embodiment of the present invention includes: a junction box 1, a lamp 2, a wiring port 3, a connecting rod 4, and a protective mechanism 5. The lamp 2 is installed outside the junction box 1, and the wiring port 3 is opened on the outer wall of the lamp 2. The connecting rod 4 is connected to one end of the lamp 2 with the wiring port 3. The protective mechanism 5 is set inside the junction box 1.

[0019] In one embodiment of this application, such as Figure 7 As shown, the wiring port 3 is equipped with a wire fixing mechanism 7, which includes a fastener 71, a bolt 73, a rotating block 75, and a second rotating shaft 76.

[0020] Fastener 71 is installed inside terminal 3, bolt 73 is threaded to the outer wall of fastener 71, rotating block 75 is connected to bolt 73, and bolt 73 passes through fastener 71 and is connected to rotating block 75. Second rotating shaft 76 is installed inside rotating block 75.

[0021] A washer 74 is fitted on the outer wall of the bolt 73, and the outer wall of the washer 74 is in contact with the outer wall of the rotating block 75.

[0022] The inner wall of the fastener 71 is fitted with a pad 72.

[0023] It should be noted that the rotating block 75 described in this embodiment of the present invention is connected to one end of the second rotating shaft 76, with the second rotating shaft 76 serving as a reference point, and the volume of the side closer to the fastener 71 is larger than the volume of the other side.

[0024] Specifically, when the cable passes through the connector 3, it passes through the fastener 71 and the pad 72 on its inner wall in sequence, completing the initial cable threading. Then, the operator turns the rotating block 75, causing it to rotate around the second rotating shaft 76 towards the fastener 71. Since the volume of the end of the rotating block 75 connected to the second rotating shaft 76 is larger on the side closer to the fastener 71 than on the other side, this end will tilt upwards during rotation, thereby causing the bolt 73 connected to it to rotate upwards along the thread of the fastener 71. When the rotating block 75 moves into the fastener 71, it will compress the pad 74 on the outer wall of the bolt 73, and then the pad 74 will distribute the pressure to the fastener 71, avoiding excessive local pressure that could damage the component. At the same time, the fastener 71, after being compressed, will further compress the pad 72, and finally the pad 72 will tightly compress the cable, firmly fixing the cable in the connector 3 and effectively preventing the cable from loosening or shifting.

[0025] The protective mechanism 5 includes a fixing plate 51, a wiring terminal 52, a fixing post 53, a connecting plate 54, a first rotating shaft 55, a cover plate 56, and a locking assembly 6.

[0026] The fixing plate 51 is fixed to the inner wall of the junction box 1, the terminal block 52 is installed on the bottom wall of the fixing plate 51, the fixing post 53 is fixed to the outer wall of the fixing plate 51, the connecting plate 54 is fixed to the inner wall of the junction box 1, the first rotating shaft 55 is rotatably connected to the outer wall of the connecting plate 54, the cover plate 56 is connected to the first rotating shaft 55, and the engaging assembly 6 is set on the inner wall of the fixing post 53.

[0027] In one embodiment of this application, such as Figure 6 As shown, the locking assembly 6 includes a latch 61, a paddle 62, a fixing block 63, a locking block 64, and a spring 65.

[0028] The bolt 61 is fixed to the outer wall of the cover plate 56 on the side near the fixing plate 51, the paddle 62 is sleeved on the outer wall of the bolt 61, the fixing block 63 is fixed inside the fixing post 53, the locking block 64 is slidably connected inside the fixing block 63, and the spring 65 is sleeved on the outside of the locking block 64.

[0029] Specifically, when fixing and managing cables that need to be connected, the cable first passes through the connector 3. Then, the worker organizes and separates the cables into two ends, passing them through the space between the fixing post 53 and the connecting plate 54, and connecting them to the corresponding terminals 52. Next, the cover plate 56 is rotated inwards. The cover plate 56 rotates towards the fixing post 53 via the first rotating shaft 55. When the cover plate 56 rotates to contact the fixing post 53, the latch 61 on the cover plate 56 inserts into the fixing post 53. At this time, the latch 61 contacts the locking block 64 inside the fixing post 53. The latch 61 then presses against the locking block 64, causing it to slide within the fixing block 63 and compressing the spring 65. After the latch 61 is fully inserted, the spring 65 rebounds, pushing the locking block 64 back to its original position. The locking block 64 then locks the latch 61, thus firmly connecting the cover plate 56 and the fixing post 53, achieving... To secure and manage cables and prevent them from loosening or falling off, when it is necessary to replace or repair cables, simply press the cover plate 56 again. The cover plate 56 pushes the latch 61, causing the paddle 62 on the outer wall of the latch 61 to contact the locking block 64. The locking block 64 slides within the fixing block 63 and compresses the spring 65. Since the paddle 62 is inclined at both ends, after the paddle 62 squeezes and slides past the locking block 64, the cover plate 56 is pulled open again. The paddle 62 contacts the locking block 64 again, slides within the fixing block 63, and compresses the spring 65. At this time, the paddle 62 drives the latch 61 to slide in the direction away from the fixing post 63 until the paddle 62 and the head of the latch 61 pass the locking block 64. Then the spring 65 rebounds and pushes the locking block 64 to reset. The locking block 64 no longer obstructs the latch 61, and the cover plate 56 can be opened to replace or repair the cables.

[0030] In one embodiment of this application, such as Figure 5 As shown, a heat sink 8 is installed on the outer wall of the lamp 2.

[0031] Understandably, the surface of the heat sink 8 is designed with multiple heat dissipation fins, which can increase the heat dissipation area and improve heat dissipation efficiency. When the lamp 2 operates for a long time, it will generate a certain amount of heat. This heat is conducted to the heat sink 8 through the outer wall of the lamp 2, and the heat sink 8 then dissipates the heat into the surrounding air quickly through the heat dissipation fins, thereby effectively reducing the operating temperature of the lamp 2.

[0032] Working principle: When the cable passes through the connector 3, the fastener 71 and the pad 72 initially fix the cable. The operator rotates the rotating block 75, which drives the second rotating shaft 76 to rotate, thereby causing the bolt 73 connected to the rotating block 75 to rotate on the threaded surface of the fastener 71. As the bolt 73 rotates, the rotating block 75 gradually moves into the fastener 71, thereby squeezing the pad 74 and the fastener 71. The fastener 71 squeezes the pad 72, which in turn squeezes the cable, making the cable more firmly fixed in the connector 3. At the same time, the pad 74 can effectively disperse the pressure of the rotating block 75 on the fastener 71, avoiding excessive local pressure that could damage the fastener 71 or the cable, ensuring the stability and reliability of the cable fixing process and achieving tight cable fixation. When the cable needs to be sorted and fixed, the operator first passes the cable through the connector 3, and after sorting the cable, passes both ends through the space between the fixing post 53 and the connecting plate 54, and then connects them to the corresponding terminal 52. Next, the cover plate 56 is rotated, and the cover plate 56 rotates towards the fixing post 53 via the first rotating shaft 55. When the cover plate 56 rotates to contact the fixing post 53, the latch 61 on the cover plate 56 is inserted into the fixing post 53. After the latch 61 contacts the locking block 64, it squeezes the locking block 64 to make it slide within the fixing block 63 and compress the spring 65. After the latch 61 is fully inserted, the spring 65 rebounds and pushes the locking block 64 to reset. The locking block 64 locks the latch 61, thereby firmly connecting the cover plate 56 and the fixing post 53, realizing the fixing and management of the cable, and preventing the cable from loosening or falling off. During the long-term operation of the lamp 2, the heat generated is conducted to the heat sink 8 through the outer wall. The heat sink 8 dissipates the heat into the surrounding air quickly through the heat dissipation fins on its surface, effectively reducing the operating temperature of the lamp 2 and ensuring the normal operation and service life of the lamp 2. When cable replacement or repair is needed, simply press the cover plate 56 again. The cover plate 56 pushes the latch 61, causing the paddle 62 on the outer wall of the latch 61 to contact the locking block 64. The locking block 64 slides within the fixing block 63 and compresses the spring 65. At this time, since the paddle 62 is inclined both top and bottom, when the cover plate 56 is pulled open, the paddle 62, under the pressure of the locking block 64, will drive the latch 61 to slide along the locking block 64 until the paddle 62 and the head of the latch 61 pass over the locking block 64. Then the spring 65 rebounds and pushes the locking block 64 back to its original position. The locking block 64 no longer obstructs the latch 61, and the cover plate 56 can be opened to replace or repair the cable.
