DETAILED DESCRIPTION

[0033] 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 part of the embodiments of the present invention, not all of them. 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.

[0034] The utility model provides a connector, comprising: at least one base plate 11, the base plate 11 comprising: a plug end and a connecting end disposed oppositely, and an intermediate section located between the plug end and the connecting end; a side wing 12 provided on each intermediate section, the side wing 12 extending from a position of the intermediate section proximate the plug end toward the connecting end and away from the base plate 11; and a purlin connecting portion connected to the connecting end of the base plate 11 and extending away from the base plate 11.

[0035] The connector provided by the present application, due to the setting of the side wings 12, on the one hand, during the process of pressing down the frame, the connector is subjected to a more uniform force and is not easily deformed, and the service life of the connector is longer. On the other hand, the side wings 12 make the frame less likely to slip, and the frame is fixed more firmly and reliably. During the assembly process, the plug-in end of the base plate 11 can be first inserted into the through hole 31 of the first connecting plate of the purlin, and the purlin connecting part is fixedly connected to the first connecting plate, and then the connector 1 and the purlin 3 are first formed into a whole. Then, after the plug-in end of the base plate 11 in the whole is aligned with the through hole 21 of the first connecting plate of the frame 2, the frame 2 is pressed downward until the second connecting plate of the frame 2 of the photovoltaic module coincides with the outer wall of the first connecting plate of the purlin 3. At this time, the side wings 12 of the connector are clamped on the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, and the photovoltaic module is fixed to the purlin 3. The present application can reduce manpower through the connector 1, simple installation, and improve installation efficiency.

[0036] Optionally, the end of the side wing 12 near the connecting end is provided with an inner tongue piece 122 and an outer tongue piece 121. The inner tongue piece 122 and the outer tongue piece 121 both extend toward the connecting end, with the inner tongue piece 122 being closer to the base plate 11 than the outer tongue piece 121. Due to the arrangement of the side wing 12, the inner tongue piece 122, and the outer tongue piece 121, on the one hand, during the process of pressing the frame downward, the connector is subjected to a more uniform force and is less likely to deform, thereby extending the life of the connector. On the other hand, the side wing 12, the inner tongue piece 122, and the outer tongue piece 121 form an X-like shape, making it difficult for the frame to slip from all directions, thereby providing a more secure and reliable fixation to the frame. In this embodiment, when the connector side wing 12 is engaged with the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, the inner tongue piece 122 and / or the outer tongue piece 121 of the connector side wing 12 are also engaged with the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, thereby fixing the photovoltaic module to the purlin 3. Specifically, the utility model provides a connecting piece 1, referring to Figure 1 and Figure 2 The connector 1 is used to connect the frame 2 and the purlin 3 of the photovoltaic module to fix the photovoltaic module on the purlin 3.

[0037] As an optional implementation, refer to Figures 1 to 8 as well as Figure 11 and Figure 12 The connector 1 comprises two stacked base plates 11, two side wings 12, and a purlin connection portion. The purlin connection portion is the portion of the connector excluding the base plates 11, side wings 12, outer tongue 121, and inner tongue 122. Alternatively, the connector may comprise only one base plate 11.

[0038] Reference Figures 1 to 8 as well as Figure 11 and Figure 12 Each substrate 11 includes: a plug-in end and a connecting end that are relatively distributed, and a middle section located between the plug-in end and the connecting end. Figures 1 to 8 as well as Figure 11 and Figure 12 In the embodiment, the upper end of the substrate 11 is the plug-in end, the lower end of the substrate 11 is the connecting end, the plug-in end and the connecting end are opposite to each other, and the middle section is located between the plug-in end and the connecting end.

[0039] The side wings 12 are provided in the middle section of each substrate 11. The side wings 12 extend from a position in the middle section adjacent to the plug-in end toward the connecting end and away from the substrate 11. This position away from the substrate 11 is also away from the stacking position of the two substrates 11. The stacking position of the two substrates 11 is where the contact surfaces of the two substrates 11 are located.

[0040] Each side wing 12 is provided with an outer tongue piece 121 and an inner tongue piece 122 at the end near the connecting end. The outer tongue piece 121 and the inner tongue piece 122 both extend toward the connecting end of the base plate 11. The inner tongue piece 122 is closer to the base plate 11 than the outer tongue piece 121. That is, the inner tongue piece 122 is closer to the stacking position of the two base plates 11 than the side wing 12, and the outer tongue piece 121 is further away from the stacking position of the two base plates 11 than the side wing 12. The purlin connecting portion is connected to the connecting end of the base plate 11 and extends away from the two base plates. 11 In this application, the relative positions of the outer tongue piece 121 and the inner tongue piece 122, the relative sizes of the outer tongue piece 121 and the inner tongue piece 122, and the number of the outer tongue piece 121 and the inner tongue piece 122 are not specifically limited. For example, referring to Figures 1 to 8 as well as Figure 11 and Figure 12 , the outer tongue piece 121 is located outside the inner tongue piece 122, the number of outer tongue pieces 121 on a side wing 12 is two, and the number of inner tongue piece 122 on a side wing 12 is one. For another example, the inner tongue piece 122 is located outside the outer tongue piece 121, the number of outer tongue piece 121 on a side wing 12 is one, and the number of inner tongue piece 122 on a side wing 12 is two. For another example, the inner tongue piece 122 is located outside the outer tongue piece 121, the number of outer tongue piece 121 on a side wing 12 is one, and the number of inner tongue piece 122 on a side wing 12 is one. For another example, the outer tongue piece 121 is located outside the inner tongue piece 122, the number of outer tongue piece 121 on a side wing 12 is one, and the number of inner tongue piece 122 on a side wing 12 is one. It should be noted that the relative sizes and numbers of the outer tongue pieces 121 and the inner tongue pieces 122 can be reasonably designed according to the size of the side wings 12 , and are not specifically limited thereto.

[0041] Reference Figure 9 The frame 2 to which the connector of the present application is applicable includes a second connecting plate, referring to Figure 10 and Figure 13The purlin 3 applicable to the connector of the present application includes a first connecting plate, the second connecting plate is the plate in the frame 2 that contacts and connects to the purlin 3, and the first connecting plate is the plate in the purlin 3 that contacts and connects to the frame 2. In the photovoltaic system, the second connecting plate and the first connecting plate partially overlap, a through hole 21 is provided in the overlapping position of the second connecting plate, and a through hole 31 is provided in the overlapping position of the first connecting plate. The plug-in end of the base plate 11 and the side wing 12 are sequentially plugged into the through hole 31 of the first connecting plate and the through hole 21 of the second connecting plate, and protrude from the second connecting plate. The inner tongue 122 and / or the outer tongue 121 are both clamped on the surface of the second connecting plate facing away from the first connecting plate, and the purlin connecting portion is fixedly connected to the first connecting plate. During the assembly process, the plug-in end of the substrate 11 can be first inserted into the through hole 31 of the first connecting plate of the purlin 3, and the purlin connecting part is fixedly connected to the first connecting plate, and then the connector 1 and the purlin 3 are first formed into a whole. Then, after the plug-in end of the substrate 11 in the whole is aligned with the through hole 21 of the second connecting plate of the frame 2, the frame 2 is pressed downward until the second connecting plate of the frame 2 of the photovoltaic module coincides with the outer wall of the first connecting plate of the purlin 3. At this time, the outer tongue 121 and / or the inner tongue 122 on the side wing 12 of the connector are clamped on the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, and the photovoltaic module is fixed on the purlin 3. In the present application, due to the arrangement of the side wings 12, the outer tongue piece 121 and the inner tongue piece 122, on the one hand, during the process of pressing down the frame, the connector 1 is subjected to a more uniform force and is not easily deformed, and the service life of the connector is longer. On the other hand, the side wings 12, the outer tongue piece 121 and the inner tongue piece 122 form an X-like shape, which makes it difficult for the frame to slip off from all directions, and the frame is fixed more firmly and reliably. The present application can reduce manpower through the connector, simplify installation, and improve installation efficiency. In this embodiment, as an optional implementation, the outer tongue piece 121 and the inner tongue piece 122 on the side wings 12 of the connector are clamped on the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, and the photovoltaic module is fixed on the purlin 3.

[0042] In this application, there is no limitation on the specific shape of the frame 2, nor on the shape of the purlin 3. For example, the frame 2 applicable to the connector of this application can be Figure 9 As shown, the second connecting plate of the frame 2 is the C side of the frame, and the purlin 3 applicable to the connector of the present application can be Figure 10 and Figure 13 The C-shaped purlin shown includes an upper flange and a lower flange that are opposite to each other, and the first connecting plate is the upper flange of the purlin 3.

[0043] Optional, see Figure 3 and Figure 4The purlin connection part includes: a first bottom plate 13 connected to the connecting end of at least one substrate 11 and extending away from the substrate. The first bottom plate 13 and the first connecting plate of the purlin 3 are welded or riveted to achieve a firm and reliable connection between the connector 1 and the purlin 3. During the assembly process, the plug-in end of the base plate 11 can be first inserted into the through hole 31 of the first connecting plate of the purlin 3, and the first base plate 13 and the first connecting plate of the purlin 3 can be welded or riveted to achieve a fixed connection, and then the connector 1 and the purlin 3 are first formed into a whole. Then, after the plug-in end of the base plate 11 in the whole is aligned with the through hole 21 of the second connecting plate of the frame 2, the frame 2 is pressed downward until the second connecting plate of the frame 2 of the photovoltaic module coincides with the outer wall of the first connecting plate of the purlin 3. At this time, the side wing 12 of the connector or the outer tongue piece 121 and the inner tongue piece 122 on the side wing 12 are clamped on the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, and the photovoltaic module is fixed to the purlin 3. The connector can reduce manpower, simplify installation, and improve installation efficiency.

[0044] Specifically, refer to Figure 3 and Figure 4 As an implementation mode, in this embodiment, the connecting member includes two stacked substrates 1, and the connecting end of each substrate 11 is connected to the first bottom plate 13. The connecting member is relatively symmetrical, and the axis of symmetry is roughly at the stacking position of the two substrates 11. The mechanical strength of the connecting member is good, and it is not easy to deform or damage.

[0045] Optionally, the first bottom plate 13 is obtained by extending the base plate 11 and then bending it. The first bottom plate 13 and the base plate 11 are easy to process, and the two are an integrated structure with good mechanical properties.

[0046] It should be noted that Figure 3 and Figure 4 In the process of connecting the frame 2 and the purlin 3, the connector shown does not require any other components except the connector 1. Fewer installation parts further improve the installation efficiency and reduce installation defects caused by missing parts.

[0047] Optional, see Figure 5 and Figure 6 The purlin connection portion includes: a second bottom plate 14 connected to the connecting end of a base plate 11 and extending away from the base plate 11, both ends of the second bottom plate 14 protruding from the base plate 11, two first side plates 15 connected to both ends of the second bottom plate 14, and the two first side plates 15 and the second bottom plate 14 form a C shape. Figure 7 and Figure 8The purlin 3 also includes: two second side panels located at both ends of the first connecting plate. During the assembly process, the plug-in end of the base plate 11 can be first inserted into the through hole 31 of the first connecting plate of the purlin 3, and the second bottom plate 14 and the two first side panels 15 can be clamped in the space formed by the first connecting plate and the two second side panels, thereby first forming the connector 1 and the purlin 3 into a whole. Then, after the plug-in end of the base plate 11 in the whole is aligned with the through hole 21 of the second connecting plate of the frame 2, the frame 2 is pressed downward until the second connecting plate of the frame 2 of the photovoltaic module coincides with the outer wall of the first connecting plate of the purlin 3. At this time, the outer tongue piece 121 and the inner tongue piece 122 on the side wing 12 of the connector are clamped on the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, thereby fixing the photovoltaic module on the purlin 3. The connector can reduce manpower, simplify installation, and improve installation efficiency.

[0048] It should be noted that the two first side panels 15 and the second bottom panel 14 can be interference fit in the process of being clamped in the space formed by the first connecting plate and the two second side panels, thereby achieving a firm connection between the connector 1 and the purlin 3. Optionally, on the basis of the two first side panels 15 and the second bottom panel 14 being clamped in the space formed by the first connecting plate and the two second side panels, the two first side panels 15 and the second bottom panel 14 and the first connecting plate and the two second side panels can be welded, riveted, etc. to strengthen the connection between the connector 1 and the purlin 3. Alternatively, on the basis of the two first side panels 15 and the second bottom panel 14 being clamped in the space formed by the first connecting plate and the two second side panels, mounting holes are provided on the two first side panels 15 and the two second side panels, and bolts, etc. are provided in the above-mentioned mounting holes to strengthen the connection between the connector 1 and the purlin 3. The method of strengthening the connection here is not limited.

[0049] Optional, see Figure 5 and Figure 6 Each first side panel 15 is provided with a snap-in piece 151 protruding in the direction away from the second bottom panel 14, and a limiting slot 32 is provided on the second side panel, and the snap-in piece 151 is snapped into the limiting slot 32 through interference fit to conveniently enhance the connection between the connector 1 and the purlin 3.

[0050] Optional, see Figure 5 , the protruding height of the snap-in piece 151 increases from the direction close to the second bottom plate 14 to the direction away from the second bottom plate 14. After the plug-in end of the subsequent substrate 11 is aligned with the through hole 21 of the second connecting plate of the frame 2, when the frame 2 is pressed downward, the presence of the snap-in piece 151 will basically not affect the snapping of the second bottom plate 14 and the two first side plates 15 into the space formed by the first connecting plate and the two second side plates.

[0051] Optional, see Figure 5 and Figure 6The purlin connection portion further includes: a bent piece 16 connected to the connecting end of another base plate 11 and extending away from the base plate 11 and toward the plug-in end of the base plate 11.

[0052] The shape of the bending piece 16 is not specifically limited, and can be, for example, arc-shaped, relatively smooth, and not prone to scratching other surfaces. Optionally, the bending piece 16 is formed by bending after extending the substrate 11. The bending piece 16 and the substrate 11 are simple to process, and the two are an integrated structure with good mechanical properties.

[0053] Specifically, refer to Figure 5 and Figure 6 As another optional embodiment, in this embodiment, the connector includes two stacked substrates 11, one comprising a second bottom plate 14 and the other comprising a bent piece 16. In this embodiment, the surface of the bent piece 16 near the plug-in end is flush with the surface of the second bottom plate 14 near the plug-in end. Subsequently, the second bottom plate 14, the two first side plates 15, and the bent piece 16 are all snapped into the space formed by the first connecting plate and the two second side plates. By providing the bent piece 16, the connector is subjected to more balanced forces during use, making it less susceptible to deformation and damage.

[0054] Specifically, as an optional implementation, in this embodiment, the bending piece 16 can also be combined with the first base plate 13. For example, the purlin connection portion includes: a first base plate 13 connected to the connecting end of one substrate 11 and extending away from the substrate 11, and a bending piece 16 connected to the connecting end of another substrate 11 and extending away from the stacking position of the two substrates 11 and toward the plug-in end of the substrate 11. The first base plate 13 and the first connecting plate are riveted or welded.

[0055] It should be noted that Figure 5 and Figure 6 In the process of connecting the frame 2 and the purlin 3, the connector shown does not require any other components except the connector 1. Fewer installation parts further improve the installation efficiency and reduce installation defects caused by missing parts.

[0056] Optional, see Figure 11 and Figure 12 The purlin connection portion includes: a third bottom plate 17 connected to the connecting end of the base plate 11 and extending in a direction away from the base plate 11, and a mounting hole 171 is opened on the third bottom plate 17. Figure 12 and Figure 13The first connecting plate of the purlin 3 is provided with a mounting hole 33. The photovoltaic bracket also includes a fastener, which passes through the mounting hole 33 on the first connecting plate and the mounting hole 171 on the third base plate 17. The fastener is fastened to form the connector 1 and the purlin 3 into a whole. Then, after the plug-in end of the base plate 11 in the whole is aligned with the through hole 21 of the second connecting plate of the frame 2, the frame 2 is pressed downward until the second connecting plate of the frame 2 of the photovoltaic module coincides with the outer wall of the first connecting plate of the purlin 3. At this time, the outer tongue piece 121 and the inner tongue piece 122 on the side wing 12 of the connector are snapped onto the surface of the second connecting plate of the frame 2 facing away from the first connecting plate, thereby fixing the photovoltaic module to the purlin 3. The connector can reduce manpower, simplify installation, and improve installation efficiency.

[0057] The specific type of fasteners herein is not limited, for example, Figure 12 The fasteners may include: bolts 4 and nuts 5, which are relatively common and easy to obtain.

[0058] Optionally, the third bottom plate 17 is obtained by extending the base plate 11 and then bending it. The third bottom plate 17 and the base plate 11 are easy to process, and the two are an integrated structure with good mechanical properties.

[0059] Specifically, refer to Figure 11 and Figure 12 As another optional implementation, in this embodiment, the purlin connecting portion of the connecting member includes: two third bottom plates 17 connected to the connecting ends of the base plate 11 and extending toward the stacking position direction of the two base plates 11.

[0060] Specifically, as an optional embodiment, in this embodiment, the bending piece 16 can also be combined with the third base plate 17. For example, the purlin connection portion includes: a third base plate 17 connected to the connecting end of one substrate 11 and extending away from the substrate 11, the third base plate 17 is provided with a mounting hole 171, and a bending piece 16 connected to the connecting end of the other substrate 11 and extending away from the stacking position of the two substrates 11 and toward the plug-in end of the substrate 11. The third base plate 17 and the first connecting plate are fastened by fasteners.

[0061] Optional, see Figures 1 to 8 as well as Figure 11 and Figure 12 The two substrates 11 are formed by folding the plate at the plug-in end. This makes stacking the two substrates 11 simple, and the two substrates 11 are an integrated structure with good mechanical properties. In this embodiment, the two substrates 11 are formed by folding the plate 180° at the plug-in end. Alternatively, the two plates may be fixedly connected at the plug-in end by welding or other means.

[0062] Specifically, based on the above embodiments and some other optional implementations, on the basis of the purlin connection part including a substrate of the second bottom plate 14, the purlin connection part including a substrate of the first bottom plate 13, and the purlin connection part including a substrate of the bent piece 16, the connecting part can be composed of any two different substrates or two identical substrates.

The purlin 3 comprises: a first connecting plate, the first connecting plate is described above, and in order to avoid repetition, it is not repeated here. The second connecting plate partially overlaps with the first connecting plate, and the second connecting plate is described above.
