Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable connection technology, specifically to a photovoltaic junction box cable fixing device. Background Technology

[0002] With the widespread application of solar photovoltaic technology, the installation scenarios for photovoltaic modules are becoming increasingly diverse, covering complex environments such as deserts, Gobi, grasslands, seas, and rooftops. In these scenarios, the junction boxes and cables of photovoltaic modules need to withstand harsh conditions such as high temperature, high humidity, ultraviolet radiation, and high-intensity external tensile forces. In existing technologies, cable fixing usually adopts simple clips or binding methods, which have the following obvious drawbacks: traditional fixing methods are prone to aging under long-term ultraviolet radiation, leading to loosening of clips and displacement or detachment of cables; when faced with external forces such as strong winds and vibrations, cables are prone to axial sliding or circumferential rotation, resulting in poor contact at the connection points. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a photovoltaic junction box cable fixing device that can adapt to complex environments, ensuring a stable connection between the photovoltaic cable and the junction box, thereby improving the service life and reliability of the photovoltaic module.

[0004] The technical solution adopted by this utility model is as follows: a photovoltaic junction box cable fixing device, including a junction box body, an arc-shaped mounting groove for cables to pass through on the side of the junction box body, a lower limit vertical retaining rib arranged at intervals along its axial direction on the bottom wall of the mounting groove, and a lower limit horizontal retaining rib arranged at intervals on both sides of the lower limit vertical retaining rib, the lower limit vertical retaining rib and the lower limit horizontal retaining rib are arranged perpendicular to each other; it also includes a pressure block fixed to the opening of the mounting groove, the pressure block is provided with a pressure groove arranged directly opposite to the mounting groove, the inner wall of the pressure groove is provided with an upper limit vertical retaining rib and an upper limit horizontal retaining rib, the lower limit vertical retaining rib and the lower limit horizontal retaining rib are respectively arranged in a one-to-one correspondence with the upper limit vertical retaining rib and the upper limit horizontal retaining rib.

[0005] In this technical solution, the mounting groove on the junction box allows photovoltaic cables to be led out, and the cables are fixed using clamping blocks. After the clamping blocks are fixed in the mounting groove, the upper limit vertical clamping ribs, upper limit horizontal clamping ribs, lower limit vertical clamping ribs, and lower limit horizontal clamping ribs located on the inner walls of the mounting groove and clamping groove are in close contact with the cable surface. The grid-like limiting structure wraps and fixes the cable at the assembly position of the clamping blocks and the mounting groove. The upper limit vertical clamping ribs and lower limit vertical clamping ribs prevent axial movement of the cable, and the upper limit horizontal clamping ribs and lower limit horizontal clamping ribs prevent circumferential rotation of the cable. This ensures that the photovoltaic cables do not experience displacement, rotation, or damage under conditions such as high temperature, high humidity, ultraviolet radiation, and high-intensity external tensile force. This improves the service life of the photovoltaic modules and reduces the risk of solar photovoltaic modules.

[0006] Preferably, the pressure block is provided with ultrasonic ribs on the outer side of the pressure groove, and the ultrasonic ribs are properly matched with the slots provided on both sides of the mounting groove.

[0007] Preferably, a cable tray is provided on the outside of the junction box, and the mounting slot is located on the upper end of the cable tray.

[0008] Preferably, the lower limit vertical clamp, the lower limit horizontal clamp, the upper limit vertical clamp, and the upper limit horizontal clamp are in the form of a trapezoidal platform structure.

[0009] Preferably, the edges of the lower limit vertical clamp, the lower limit horizontal clamp, the upper limit vertical clamp, and the upper limit horizontal clamp are rounded.

[0010] The beneficial effects of this utility model are as follows: After the mounting groove and the pressure block assembly part are assembled, the cable is fixed by a grid-like limiting structure. The upper and lower limit vertical clamps prevent the axial position of the cable, and the upper and lower limit horizontal clamps prevent the circumferential rotation of the cable. This ensures that the photovoltaic cable does not experience displacement, rotation, or damage under conditions such as high temperature, high humidity, ultraviolet radiation, and high-intensity external tensile force. This improves the service life of the photovoltaic module, reduces the risk of solar photovoltaic modules, and has extremely high market promotion value. Attached Figure Description

Detailed Implementation

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0018] like Figures 1 to 3 As shown in the figure, a specific embodiment of this utility model provides a photovoltaic junction box cable fixing device, which is used to install photovoltaic cables. Specifically, it includes a junction box body 100, and the side of the junction box body 100 is provided with an arc-shaped mounting groove 110 for the cable to pass through. The bottom wall of the mounting groove 110 is provided with lower limit vertical retaining ribs 120 arranged at intervals along its axial direction. Lower limit horizontal retaining ribs 130 are also arranged at intervals on both sides of the lower limit vertical retaining ribs 120. The lower limit vertical retaining ribs 120 and the lower limit horizontal retaining ribs 130 are arranged perpendicular to each other. It also includes a pressure block 200 fixed to the opening of the mounting groove 110. The pressure block 200 is provided with a pressure groove 210 arranged directly opposite to the mounting groove 110. The inner wall of the pressure groove 210 is provided with upper limit vertical retaining ribs 220 and upper limit horizontal retaining ribs 230. The upper limit vertical retaining ribs 220 and upper limit horizontal retaining ribs 230 are respectively arranged in a one-to-one correspondence with the lower limit vertical retaining ribs 120 and lower limit horizontal retaining ribs 130.

[0019] like Figures 1 to 3 As shown, through the above configuration, the mounting groove 110 provided on the junction box 100 in this embodiment can lead out the photovoltaic cable, and the clamping block 200 is used to fix the cable. After the clamping block 200 is fixed in the mounting groove 110, the photovoltaic cable is constrained between the mounting groove 110 and the clamping groove 210. At the same time, the upper limit vertical clamping rib 220, the upper limit horizontal clamping rib 230, the lower limit vertical clamping rib 120, and the lower limit horizontal clamping rib 130 located on the inner wall of the mounting groove 110 and the clamping groove 210 are in close contact with the cable surface, utilizing the horizontal and vertical clamping ribs. The arranged cable clamps form a grid-like limiting structure, thereby wrapping and fixing the cable at the assembly position of the pressure block 200 and the mounting groove 110. The upper limit vertical clamps 220 and the lower limit vertical clamps 120 prevent the axial position of the cable, while the upper limit horizontal clamps 230 and the lower limit horizontal clamps 130 prevent the circumferential rotation of the cable. This ensures that the photovoltaic cable does not experience displacement, rotation, or damage under conditions such as high temperature, high humidity, ultraviolet radiation, and high-intensity external tensile force. As a result, the service life of the photovoltaic module is improved, and the risk of solar photovoltaic module failure is reduced.

[0020] like Figures 1 to 3As shown, in this embodiment, an ultrasonic rib 240 is provided on the outside of the pressure groove 210 corresponding to the pressure block 200. The ultrasonic rib 240 is properly matched with the slots provided on both sides of the mounting groove 110, so that the pressure block 200 can be stably fixed in the mounting groove 110 position by the ultrasonic rib 240.

[0021] like Figures 1 to 3 As shown, this embodiment also includes a cable tray on the outside of the junction box 100, with the mounting groove 110 located at the upper end of the cable tray. The cable tray can be equipped with the mounting groove 110, which, when assembled and fixed with the pressure block 200, stably fixes the photovoltaic cable.

[0022] like Figures 1 to 3 As shown, to ensure the stability of the photovoltaic cable fixation while avoiding damage to the cable caused by the clamping structure, the lower limit vertical clamps 120 and 130, and the upper limit vertical and horizontal clamps 220 and 230 in this embodiment are trapezoidal structures. Simultaneously, the edges of the lower limit vertical clamps 120 and 220, and the upper limit horizontal clamps 230 and 130 are rounded. Thus, the trapezoidal structure of each clamping structure ensures stable contact with the surface of the photovoltaic cable after assembly. Because the edges of the limiting clamps are rounded, surface damage to the photovoltaic cable after manual handling is avoided, further improving the reliability of the photovoltaic cable installation.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
