[0038] An embodiment of the present application provides a connector, which will be described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 3 , shows a schematic structural diagram of a connector provided in an embodiment of the present application, referring to Figure 4 , showing a schematic structural diagram of an elastic part of a connecting piece provided in an embodiment of the present application.

[0040] like Figures 1 to 3As shown, the present application provides a connector for use in photovoltaic modules, the connector comprising two clamping members 1 and a telescopic assembly 2 arranged between the two clamping members 1; the two clamping members 1 are arranged back to back along a first direction, and the clamping members 1 are used to clamp the photovoltaic module; the telescopic assembly 2 comprises an elastic member 21, and the elastic member 21 is telescopic along the first direction to increase or decrease the distance between the two clamping members 1 along the first direction.

[0041] In the embodiment of the present application, since the clamping member 1 and the telescopic assembly 2 are provided, the clamping member 1 can reliably clamp the photovoltaic assembly, and the telescopic assembly 2 can realize the change of the distance between the two clamping members 1. During the installation of the photovoltaic assembly, it is only necessary to apply external force to compress the connector to adapt to the installation hole of the photovoltaic assembly, and then remove the external force so that the clamping members 1 on both sides clamp the photovoltaic assembly to complete the installation of the photovoltaic assembly. That is, compared with the bolt connection method of the prior art, the connection method of the connector of the embodiment of the present application is simple and fast, which is conducive to improving the installation efficiency of the photovoltaic assembly. In addition, since the telescopic assembly 2 is provided, the length of the connector is adjustable, so that it can adapt to installation holes of different sizes, which is conducive to the promotion and application of the connector. It should be noted that the first direction in the embodiment of the present application refers to the axial direction of the connector, that is, the telescopic direction of the connector.

[0042] In actual applications, a photovoltaic module includes a photovoltaic bracket and a photovoltaic panel mounted on the photovoltaic bracket. When the connector of the embodiment of the present application is used, it is necessary to open mounting holes for mounting the connector around the photovoltaic panel in advance according to actual needs, such as the specifications of the photovoltaic module and the layout of the photovoltaic bracket. During the assembly of the photovoltaic module, first, the photovoltaic panel is stacked on the photovoltaic bracket; second, the connector is compressed to fit the mounting holes, and the photovoltaic panel and the photovoltaic bracket are clamped by the clamping members 1 on both sides, thereby achieving a reliable connection between the photovoltaic panel and the photovoltaic bracket. The entire installation process is simple and convenient, which is not only conducive to the early installation of the photovoltaic module, but also provides convenience for later maintenance and replacement.

[0043] In some optional embodiments of the present application, the telescopic assembly 2 also includes a first shell 22 and a second shell 23, and the second shell 23 is slidably connected to the first shell 22 along the first direction; the first shell 22 and the second shell 23 enclose a cavity to form an elastic member 21 in the cavity, and under the telescopic action of the elastic member 21, the second shell 23 slides relative to the first shell 22 along the first direction.

[0044] In the embodiment of the present application, the second housing 23 is connected to the first housing 22 by sliding along the first direction, and the elastic member 21 is disposed within the cavity formed by the first and second housings 22, 23. Thus, when an external force is applied to the connecting member along the first direction, the elastic member 21 is compressed, and the second housing 23 slides relative to the first housing 22, causing the telescopic assembly 2 to enter a compressed state and the distance between the two clamping members 1 at both ends of the telescopic assembly 2 to decrease. When the external force is removed, the elastic member 21 extends, and the second housing 23 slides relative to the first housing 22, causing the telescopic assembly 2 to enter an extended state and the distance between the two clamping members 1 at both ends of the telescopic assembly 2 to increase.

[0045] It should be noted that the lengths of the first and second shells 22, 23 along the first direction can be adjusted as needed and are not limited here. Furthermore, the cross-sectional shapes of the first and second shells 22, 23 perpendicular to the first direction can be circular, elliptical, rectangular, polygonal, or other shapes, and are not limited here. It should be understood that to facilitate the sliding connection between the first and second shells 22, 23, the first and second shells 22, 23 in the present embodiment have the same cross-sectional shape and matching cross-sectional dimensions perpendicular to the first direction.

[0046] In practical applications, the clamping member 1 includes a first clamping member 11 and a second clamping member 12. Along a first direction, the first housing 22 has a first end and a second end that are disposed away from each other; the second housing 23 has a third end and a fourth end that are disposed away from each other. The first end of the first housing 22 is fixedly connected to the first clamping member 11, the fourth end of the second housing 23 is fixedly connected to the second clamping member 12, and the second end of the first housing 22 is slidably connected to the third end of the second housing 23. Thus, when the second housing 23 slides relative to the first housing 22, the spacing between the second clamping member 12 and the first clamping member 11 changes, thereby adapting to different mounting hole positions and realizing the application of the connector in different scenarios.

[0047] In some optional embodiments of the present application, the second shell 23 is provided with a slide groove 231 extending along the first direction, and the first shell 22 is provided with a limiting protrusion 221 , and the limiting protrusion 221 is slidably connected to the slide groove 231 .

[0048] In the embodiment of the present application, since the second housing 23 is provided with a slide groove 231, the first housing 22 is correspondingly provided with a limiting protrusion 221, which is slidably connected to the slide groove 231. In this way, on the one hand, the limiting protrusion 221 can guide the slide groove 231 to slide in the first direction; on the other hand, the minimum and maximum lengths of the telescopic assembly 2 can be limited by the abutment between the limiting protrusion 221 and the ends of the slide groove 231.

[0049] It should be noted that the number of the slide grooves 231 and the limiting protrusions 221 can be adjusted as needed by those skilled in the art and is not limited herein. It should be understood that the number of the slide grooves 231 and the limiting protrusions 221 should be consistent, and when multiple slide grooves 231 are provided, they can be located on the same side of the second housing 23 or on different sides of the second housing 23, but the multiple slide grooves 231 should be arranged parallel to each other. The position of the limiting protrusions 221 on the first housing 22 can be adjusted by those skilled in the art as needed. To increase the length range of the telescopic assembly 2 and adapt the connector to different mounting hole locations, the limiting protrusion 221 in the embodiment of the present application is located at the end of the first housing 22 facing away from the first clamping member 11. Furthermore, the limiting protrusion 221 in the embodiment of the present application is essentially an inverted structure. When the telescopic assembly 2 is extended, the limiting protrusion 221 securely engages with the end of the slide groove 231 facing away from the second housing 23, effectively preventing the limiting protrusion 221 from disengaging from the slide groove 231.

[0050] like Figure 4 As shown, the elastic member 21 includes a fixing plate 212 and a spring 211 ; two fixing plates 212 are provided, and the two fixing plates 212 are spaced apart along the first direction; the spring 211 is provided between the two fixing plates 212 , and the spring 211 is extended and retracted along the first direction.

[0051] Furthermore, a plurality of springs 211 are provided.

[0052] In the embodiment of the present application, the elastic member 21 includes two fixed plates 212 disposed opposite each other and a spring 211 disposed between the fixed plates 212. Thus, since the two ends of the spring 211 are respectively fixed to the fixed plates 212, and the two fixed plates 212 are fixed in position when the connector is assembled, the spring 211 can be easily extended and retracted along a predetermined direction, i.e., a first direction. Since multiple springs 211 are provided, compared to a single spring 211, the multiple springs 211 can improve the mechanical strength of the elastic member 21, thereby delaying the failure of the elastic member 21 and increasing the service life of the connector.

[0053] It should be noted that when the elastic member 21 is in an uncompressed state, that is, in a naturally stretched state, the first clamping member 11 and the second clamping member 12 have a maximum distance therebetween. The fixing plate 212 can be circular, elliptical, rectangular, polygonal or other shapes, which are not limited here; it is understood that since the elastic member 21 is installed in the cavity formed by the first shell 22 and the second shell 23, the shape of the fixing plate 212 should be compatible with the cross-sectional shape of the first shell 22 and the second shell 23 along the first direction perpendicular to the first direction. In addition, when multiple springs 211 are provided, the multiple springs 211 should be connected to the fixing plate 212 at the same intervals, so that the applied external force can be evenly distributed on each spring 211, further improving the smoothness of the sliding of the second shell 23 relative to the first shell 22.

[0054] In some optional embodiments of the present application, the clamping member 1 includes a fixing portion 13, which is connected to the telescopic assembly 2; the fixing portion 13 has two ends that are arranged away from each other, and along the first direction, two clamping bodies 14 are symmetrically arranged at both ends of the fixing portion 13; each clamping body 14 is inclinedly provided with a pressure plate 141 at one end away from the fixing portion 13, and at least a portion of the pressure plate 141 close to one end of the clamping body 14 extends toward the center direction of the clamping member 1 to form a convex tooth 142, and the convex tooth 142 abuts against the photovoltaic component.

[0055] In the embodiment of the present application, since the clamping member 1 includes a fixing portion 13 and two clamping bodies 14 symmetrically arranged at both ends of the fixing portion 13 along the first direction, the clamping of the photovoltaic module can be achieved by clamping the two clamping bodies 14. Since the clamping body 14 is tilted and provided with a pressure plate 141 at one end away from the fixing portion 13, that is, the pressure plate 141 does not fit the photovoltaic module, it is convenient for the staff to apply an extrusion force to the clamping member 1 to deform the clamping member 1, and then easily remove the clamping member 1 from the photovoltaic module. Specifically, during the disassembly process of the connector, the staff applies relative extrusion pressure to the two pressure plates 141, and at the same time compresses the telescopic assembly 2 along the first direction to remove the clamping member 1 on one side from the photovoltaic module, and disassembles the clamping member 1 on the other side in the same manner, thereby achieving the disassembly of the entire connector. Because at least a portion of the pressure plate 141 near one end of the clamping body 14 extends toward the center of the clamping member 1 to form protruding teeth 142, during installation of the connector, the protruding teeth 142 provided on both sides of the clamping body 14 respectively abut against the upper and lower end surfaces of the photovoltaic module. Specifically, the upper protruding teeth 142 abut against the upper surface of the photovoltaic panel, and the lower protruding teeth 142 abut against the lower surface of the bracket, thereby clamping and securing the photovoltaic panel and the photovoltaic bracket. Furthermore, in actual application, the protruding teeth 142 on both sides can adapt to photovoltaic modules of different thicknesses by varying degrees of deformation.

[0056] It should be noted that the clamping member 1 of the embodiment of the present application is generally U-shaped. Furthermore, the protruding teeth 142 on the two clamping bodies 14 can be arranged relative to each other or staggered, without limitation herein. It is understood that when the protruding teeth 142 on the two clamping bodies 14 are arranged relative to each other, the clamped position of the photovoltaic module will be subjected to relative clamping forces, thereby improving the clamping stability and reliability of the clamping member 1 on the photovoltaic module. Furthermore, the number of protruding teeth 142 can be adjusted by those skilled in the art based on actual needs, without limitation herein. It is understood that when multiple protruding teeth 142 are provided, the multiple protruding teeth 142 should be evenly arranged on the clamping body 14 along the second direction so that the clamping force is evenly distributed across each protruding tooth 142.

[0057] In some optional embodiments of the present application, the pressing plate 141 and the clamping body 14 have an inclined angle, and the inclined angle is an obtuse angle.

[0058] In the embodiment of the present application, the pressure plate 141 and the clamping body 14 have an obtuse angle θ. Thus, when a worker applies a squeezing force to move the pressure plate 141 toward the photovoltaic module, the protruding teeth 142 at the other end of the pressure plate 141 will move away from the photovoltaic module, thereby reducing the clamping effect of the protruding teeth 142 on the photovoltaic module. Furthermore, the squeezing force is transmitted to the clamping body 14 through the connection between the pressure plate 141 and the clamping body 14, causing the clamping body 14 to bulge away from the center of the clamp 1, thereby reducing or even eliminating the clamping effect of the clamping body 14 on the photovoltaic module.

[0059] It should be noted that the tilt angle θ can be different angles such as 100°, 130°, 160°, etc., and those skilled in the art can adjust it according to actual needs. The embodiment of the present application does not limit the specific value of the tilt angle θ.

[0060] In some optional embodiments of the present application, the clamping body 14 includes a first connecting portion 144 and a second connecting portion 145 spaced apart along a second direction, and the second direction is perpendicular to the first direction; a clamping plate 143 is provided between the first connecting portion 144 and the second connecting portion 145, and the clamping plate 143 has a fixed end and a free end which are arranged away from each other, the fixed end is connected to the fixed portion 13, and the free end extends toward the center of the clamping member 1; when the first connecting portion 144 and the second connecting portion 145 are protruding in a direction away from the center of the clamping member 1, the free end of the clamping plate 143 abuts against the photovoltaic component.

[0061] In the embodiment of the present application, since the clamping body 14 includes a first connecting portion 144, a second connecting portion 145 and a clamping plate 143 arranged between the first connecting portion 144 and the second connecting portion 145, and the clamping plate 143 has a free end, when the first connecting portion 144 and the second connecting portion 145 protrude in a direction away from the center of the clamping member 1, the free end of the clamping plate 143 abuts against the photovoltaic component, thereby realizing secondary clamping of the photovoltaic component, which is beneficial to improving the connection reliability between the connector and the photovoltaic component.

[0062] It should be noted that the clamping plate 143 of the embodiment of the present application is roughly arc-shaped. When the photovoltaic module is not clamped, the free end of the clamping plate 143 is slightly higher than the clamping body 14, that is, the free end of the clamping plate 143 is located on the side of the clamping body 14 away from the center of the clamping member 1 and there is a certain distance between the free end and the clamping body 14. When the photovoltaic module is clamped, the first connecting portion 144 and the second connecting portion 145 on both sides of the clamping plate 143 protrude in the direction away from the center of the clamping member 1. As the degree of protrusion increases, the distance between the free end of the clamping plate 143 and the photovoltaic module continuously decreases until the free end of the clamping plate 143 abuts against the photovoltaic module, thereby achieving the clamping effect on the photovoltaic module. When the photovoltaic module is not clamped, the distance between the free end of the clamping plate 143 and the clamping body 14 can be adjusted by those skilled in the art according to actual needs, and is not limited here.

[0063] The present application also provides a photovoltaic assembly, comprising: a photovoltaic panel and a photovoltaic bracket; and a connector according to any of the above embodiments, the connector being used to clamp the photovoltaic panel and the photovoltaic bracket. The specific structure of the connector has been described in detail in the above embodiments and will not be repeated here.

[0064] The following provides an example of a process for assembling a photovoltaic module using the connector according to an embodiment of the present application:

[0065] First, compress the connector and place it into the mounting hole of the photovoltaic module;

[0066] Secondly, the two clamping members 1 located on both sides of the connecting member clamp the photovoltaic component under the extension action of the telescopic component 2; in this process, the convex teeth 142 first contact the photovoltaic component and deform, and the deformed convex teeth 142 rotate in the direction away from the center of the clamping member 1, thereby driving the first connecting part 144 and the second connecting part 145 to bulge in the direction away from the center of the clamping member 1 until the free end of the clamping plate 143 abuts against the photovoltaic component. At this point, under the dual clamping action of the convex teeth 142 and the clamping plate 143, the photovoltaic component is reliably fixed.

[0067] In summary, the connector provided by the embodiments of the present application has at least the following advantages:

[0068] In an embodiment of the present application, the connector includes two clamping members and a telescopic assembly disposed between the two clamping members; the two clamping members are disposed opposite each other along a first direction, and the clamping members are used to clamp the photovoltaic module; the telescopic assembly includes an elastic member that expands and contracts along the first direction to increase or decrease the distance between the two clamping members along the first direction. Thus, due to the provision of the clamping members and the telescopic assembly, the clamping members can reliably clamp the photovoltaic module, and the telescopic assembly can achieve a change in the distance between the two clamping members. During the installation of the photovoltaic module, it is only necessary to apply an external force to compress the connector to adapt to the mounting hole of the photovoltaic module, and then remove the external force so that the clamping members on both sides clamp the photovoltaic module to complete the installation of the photovoltaic module. That is, compared to the bolt connection method of the prior art, the connection method of the connector of the embodiment of the present application is simple and quick, which is conducive to improving the installation efficiency of the photovoltaic module. In addition, due to the provision of the telescopic assembly, the length of the connector is adjustable, so that it can adapt to mounting holes of different sizes, which is conducive to the promotion and application of the connector.
