Description

Technical Field

[0001] This invention relates to the field of photovoltaic device technology, and more specifically, to a photovoltaic device. Background Technology

[0002] Photovoltaic modules convert solar energy into light energy, and typically connect to external devices via wires to provide power. However, these wires are often exposed and have a high degree of freedom of movement, making them prone to getting tangled in the photovoltaic modules during use. This hinders user operation and may pose safety hazards. Summary of the Invention

[0003] The present invention provides a photovoltaic device.

[0004] The photovoltaic device according to the embodiments of this application includes a photovoltaic module, a junction box, a socket, and a retaining member. The photovoltaic module includes a photovoltaic panel and a frame, with the frame covering the edge of the photovoltaic panel. The junction box is electrically connected to the photovoltaic panel. The socket is electrically connected to the junction box. The retaining member includes a first clamping part and a second clamping part. The first clamping part clamps onto the frame, and the second clamping part clamps onto the socket.

[0005] The photovoltaic device in this embodiment is clamped to the frame by the first clamping part of the clamping member and the second clamping part clamps the socket, thereby effectively restricting the freedom of movement of the socket and preventing the wires from getting tangled on the photovoltaic module to a certain extent, reducing the risk of safety hazards.

[0006] In some embodiments, the first clamping part is formed with a first retaining groove, a portion of the frame is accommodated in the first retaining groove, the first retaining groove is formed with two first openings opposite each other along the length direction of the side of the frame, and the frame passes through the two first openings.

[0007] Thus, the first retaining groove forms two opposing first openings along the length of the side of the frame. The frame passes through the two first openings, so that the first retaining groove can act as a sliding groove to cooperate with the side of the frame. This allows the retaining component to drive the socket to slide along the side of the frame, avoiding damage to components caused by the pulling force of the wires when the photovoltaic module is opened and closed.

[0008] In some embodiments, the first clamping part includes a base plate and two first clamping pieces that are opposite each other along a first direction. Both first clamping pieces are connected to the base plate, and the first clamping pieces and the base plate together form a first clamping groove.

[0009] Thus, by forming a first retaining groove together with the first clip and the bottom plate, covering the side of the frame, the movement of the first retaining part relative to the frame is effectively restricted in the first direction and in the direction where the bottom plate is opposite to the frame, which in turn helps to restrict the position of the socket relative to the photovoltaic module.

[0010] In some embodiments, the side of the first clip away from the substrate forms a protruding edge, which engages with the frame.

[0011] In this way, the first clip forms a protruding edge that engages with the frame on the side away from the base plate, thereby enhancing the clamping stability of the first clip on the frame and preventing the clip from slipping off the frame.

[0012] In some embodiments, the second clamping part includes two second clamping pieces that are opposite each other along the first direction. The second clamping pieces are connected to the bottom piece and are located on the side of the bottom piece away from the first clamping piece. The second clamping pieces and the bottom piece together form a second clamping groove.

[0013] Thus, by forming a first retaining groove and a second retaining groove on opposite sides of the substrate with two first clamping pieces and two second clamping pieces respectively, the two sides of the retaining piece clamp the frame and the socket respectively, effectively limiting the position of the second power terminal relative to the photovoltaic module, and preventing wire tangling to a certain extent. In addition, the retaining piece has a simple structure and is easy to manufacture.

[0014] In some embodiments, a first groove is formed between the ends of the two first clips away from the substrate, and a second groove is formed between the ends of the two second clips away from the substrate. The first groove and the second groove are opposite to each other along a second direction, which is perpendicular to the first direction.

[0015] Thus, by having the first and second slots facing away from each other in the second direction, the wires are fixed to the outside of the frame away from the photovoltaic panel in the second direction through the socket, reducing interference between the wires and the photovoltaic panel.

[0016] In some embodiments, the second clip has an arc-shaped end on the side away from the base plate, and the curvature of the arc-shaped end matches the curvature of the outer peripheral surface of the socket.

[0017] Thus, by forming an arc-shaped end that matches the outer periphery of the socket on the side of the second clip away from the base plate, the second clip provides stable clamping of the socket and prevents the socket from slipping out of the second retaining groove.

[0018] In some embodiments, the second clamping portion is formed with a second retaining groove, the socket is at least partially accommodated in the second retaining groove, the outer surface of the socket is formed with a limiting structure, the groove wall of the second retaining groove is formed with a limiting portion that cooperates with the limiting structure, one of the limiting structure and the limiting portion is a protrusion, and the other is a groove, the protrusion is at least partially accommodated in the groove.

[0019] Thus, the socket is at least partially accommodated in the second retaining groove, and the outer surface of the socket and the groove wall of the second retaining groove are connected by a limiting structure and a limiting part, thereby achieving the effect of fixing the socket in the second retaining groove.

[0020] In some embodiments, the limiting structure is a groove and the limiting part is a protrusion. The groove is formed on the side surface of the socket facing the frame, and the protrusion protrudes from the groove wall of the second retaining groove facing away from the frame.

[0021] Thus, the limiting structure is a groove formed on the side of the socket facing the frame, and the limiting part is a protrusion formed on the groove wall of the second holding groove facing away from the frame, so that the protrusion and the groove engage on the side of the second clamping part against the frame, which is conducive to stable engagement and thus plays a good limiting role for the socket.

[0022] In some embodiments, the second retaining slot is formed with two second openings opposite each other along a third direction, and the socket passes through the two second openings, with the third direction parallel to the length direction of the side of the frame.

[0023] In this way, the socket can be inserted into or removed from the second retaining slot along the length of the frame. During the installation and removal process, the socket is less likely to interfere with the frame, which improves the ease of use of the retaining component.

[0024] In some implementations, the protrusions and recesses extend along a third direction, and the distance by which the protrusions and recesses extend along the third direction is less than the dimension of the socket in the third direction.

[0025] Thus, the protrusions and grooves along the third direction facilitate the insertion of the socket into the second retaining slot along the third direction, and the distances of the protrusions and grooves along the third direction are all less than the dimensions of the socket in the third direction, thereby preventing the socket from slipping out.

[0026] In some implementations, the socket and the second clamping part are an integral structure.

[0027] In this way, the socket is integrated with the second clamping part, so that the wire is fixed relative to the clamping part at the second power terminal, thereby restricting the freedom of movement of the wire and preventing the wire from getting tangled on the photovoltaic module. This design also saves the assembly steps of the socket and the clamping part. When fixing the wire, only the first clamping part needs to be clamped to the frame, which further simplifies the operation.

[0028] In some implementations, the photovoltaic device also includes a plug, with the plug and socket located on opposite sides of the junction box.

[0029] In this way, both the plug and the socket are connected to the junction box via wires, and the plug and socket are positioned on opposite sides of the junction box, thereby further preventing the wires from getting tangled.

[0042] Please see Figure 1 and Figure 2 The photovoltaic device 100 of this application includes a photovoltaic module 10, a junction box 20, a wire 30, and a retaining member 40. The photovoltaic module 10 includes a photovoltaic panel 11 and a frame 12, with the frame 12 covering the edge of the photovoltaic panel 11. The junction box 20 is electrically connected to the photovoltaic panel 11. The retaining member 40 includes a first clamping part 41 and a second clamping part 42. The first clamping part 41 clamps onto the frame 12, and the second clamping part 42 clamps onto the socket 33.

[0043] In this embodiment of the application, the photovoltaic device 100 is clamped to the frame 12 by the first clamping part 41 of the clamping member 40 and the second clamping part 42 clamps the socket 33, thereby effectively restricting the degree of freedom of movement of the socket 33 and preventing the wire 30 from getting tangled on the photovoltaic module 10 to a certain extent, thus reducing the risk of safety hazards.

[0044] Specifically, the front of the photovoltaic panel 11 faces the light source, and the photovoltaic panel 11 can convert light energy into electrical energy. The frame 12 can be made of metal, providing high structural strength. For example, the edges of the photovoltaic panel 11 are straight, the frame 12 is square, and the photovoltaic module 10 as a whole has a roughly square plate-like structure. The junction box 20 is located on the front of the photovoltaic panel 11, and the junction box 20 can be used to store the power-connecting wires 30.

[0045] In some embodiments, the photovoltaic device 100 further includes a conductor 30, which includes a first terminal 31 and a second terminal 32. The first terminal 31 is connected to a junction box 20, and the second terminal 32 is provided with a socket 33. The conductor 30 may be a cable. The first terminal 31 is fixedly connected to the junction box 20 and electrically connected to the photovoltaic panel 11 through the junction box 20. The socket 33 can be plugged into another cable or a plug of an electrical device, thereby outputting electrical energy from the photovoltaic panel 11.

[0046] The retaining member 40 is mounted on the frame 12 via the first clamping part 41, and the second clamping part 42 is fixedly connected to the first clamping part 41. The first clamping part 41 and the second clamping part 42 can be an integral structure. The second clamping part 42 is positioned away from the frame 12 and the photovoltaic panel 11, so that the socket 33 is fixed on the side of the frame 12 opposite to the photovoltaic panel 11 via the second clamping part 42.

[0047] The second clamping part 42 clamps the socket 33 and can be fixedly connected to the socket 33. Further, the second clamping part 42 and the socket 33 can be fixedly connected by at least one of the following methods: welding, riveting, gluing, snap-fit ​​connection, threaded connection, integral molding, etc. In some embodiments, such as... Figure 2 As shown, the second clamping portion 42 forms a second retaining groove 42 and engages with the socket 33. In other embodiments, such as Figure 5 As shown, the second clamping part 42 and the socket 33 are an integral structure.

[0048] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the first clamping part 41 is formed with a first retaining groove 411, and a portion of the frame 12 is accommodated in the first retaining groove 411. The first retaining groove 411 is formed with two first openings 415 opposite each other along the length direction (X direction as shown in the figure) of the side of the frame 12, and the frame 12 passes through the two first openings 415.

[0049] Thus, the first retaining groove 411 forms two first openings 415 opposite each other along the length direction of the side of the frame 12. The frame 12 passes through the two first openings 415, so that the first retaining groove 411 can slide along the side of the frame 12 as a sliding groove. Thus, the retaining member 40 can drive the socket 33 to slide along the side of the frame 12, avoiding damage to the components caused by the pulling force of the wire 30 when the photovoltaic module 10 is opened and closed.

[0050] It should be noted that the photovoltaic device 100 typically uses folded photovoltaic modules 10. When the photovoltaic module 10 is opened and closed, the change in the length of the conductor 30 will generate a certain pulling force. Thus, two first openings 415 opposite each other along a third direction are formed by the first retaining groove 411. The frame 12 passes through the two first openings 415, allowing the retaining member 40 to drive the socket 33 to slide along the third direction on the frame 12, thereby avoiding damage to the components caused by the pulling force of the conductor 30.

[0051] Specifically, the first clamping part 41 and the second clamping part 42 are flush with each other along the extension direction of the photovoltaic panel 11. The frame 12 can be formed by connecting and enclosing a plurality of support rods 121 and connectors 122 end to end in sequence. The first clamping part 41 can clamp onto one of the support rods 121 that make up the frame 12, covering part of the rod from the side of the frame 12 away from the photovoltaic panel 11. The opposite direction of the two first openings 145 is the extension direction of the support rod 121 clamped by the first clamping part 41.

[0052] A support rod 121 of the frame 12 passes through two first openings 415. The retaining member 40 can slide a certain distance along the support rod 121, causing the socket 33, which is fixedly connected to the second clamping part 42, to move relative to the frame 12. This allows the wire 30 to have a certain degree of freedom of movement in the length direction of the side of the frame 12. Thus, when the length of the wire 30 changes or is pulled, the retaining member 40 can provide a margin of movement to avoid damage to the components.

[0053] Optionally, the inner contour of the first retaining groove 411 matches the shape and size of the frame 12 to ensure stable engagement between the frame 12 and the first retaining groove 411. For example, the frame 12 is square, the support rod 121 is a straight rod with a square cross-section, and the first retaining groove 411 is a square groove with a cross-sectional shape similar to that of the support rod 121, and matches the cross-sectional size of the support rod 121.

[0054] The first retaining groove 411 accommodates a portion of the frame 12, and the second clamping part 42 is fixedly connected to the socket 33, so that the retaining member 40 connects the frame 12 and the socket 33 at the same time, effectively limiting the position of the wire 30 next to the photovoltaic module 10 and preventing the wire 30 from getting tangled on the photovoltaic module 10.

[0055] Please see Figure 4 In some embodiments, the first clamping part 41 includes a base plate 412 and two first clamping pieces 413 that are opposite each other along a first direction (Z direction as shown in the figure). Both first clamping pieces 413 are connected to the base plate 412, and the first clamping pieces 413 and the base plate 412 together form a first clamping groove 411.

[0056] Thus, the first clip 413 and the bottom piece 412 together form the first retaining groove 411, which covers the side of the frame 12, effectively restricting the movement of the first retaining part 41 relative to the frame 12 in the first direction and in the direction opposite to the bottom piece 412 and the frame 12, thereby helping to restrict the position of the socket 33 relative to the photovoltaic module 10.

[0057] Specifically, the first clip 413 forms an angle with the base plate 412, and the two first clips 413 are respectively connected to the two ends of the base plate 412 along the first direction. The first clip 413 and the base plate 412 cover a portion of the outer side of a support rod 121 of the frame 12. The first clip 413 covers the upper and lower sides of the support rod 121 opposite to each other along the first direction. The surface of the base plate 412 forming the first holding groove 411 is opposite to the side of the support rod 121 away from the photovoltaic panel 11. Thus, the first clamping part 41 plays a limiting role in the first direction and in the direction where the base plate 412 is opposite to the frame 12.

[0058] Furthermore, the first clamping piece 413 can form an angle of approximately 90° with the substrate 412, the support rod 121 clamped by the first clamping part 41 has a square cross section, and the substrate 412 can face the surface of the photovoltaic panel 11 opposite to the clamped support rod 121.

[0059] Furthermore, a portion of the frame 12 is accommodated in the first retaining groove 411, and the surface of the base plate 412 surrounding the first retaining groove 411 can abut against the frame 12 being held.

[0060] Please see Figure 2 and Figure 4 In some embodiments, the side of the first clip 413 away from the base plate 412 forms a protruding edge 4131, which engages with the frame 12.

[0061] Thus, by forming a protruding edge 4131 that engages with the frame 12 on the side of the first clip 413 away from the base plate 412, the clamping stability of the first clip 413 on the frame 12 is enhanced, preventing the clamping member 40 from slipping off the frame 12.

[0062] Specifically, the protruding edge 4131 forms an angle with the first clip 413 and extends toward the other first clip 413, such that the relative distance between the two protruding edges 4131 is narrower than the relative distance between the first clips 413, to prevent the frame 12 from disengaging from the first slot 414 and the first retaining slot 411. For example, the first retaining slot 411 is a square slot, the two first clips 413 are approximately parallel to each other, and both form an angle of approximately 90° with the base plate 412. The first clips 413 are engaged with the inner edge of the frame 12 through the protruding edge 4131.

[0063] Please see Figure 4In some embodiments, the second clamping part 42 includes two second clamping pieces 424 that are opposite each other in the first direction. The second clamping pieces 424 are connected to the bottom piece 412 and are located on the side of the bottom piece 412 away from the first clamping piece 413. The second clamping pieces 424 and the bottom piece 412 together form a second holding groove 422.

[0064] Thus, by forming a first retaining groove 411 and a second retaining groove 422 on opposite sides of the base plate 412 with two first clamping pieces 413 and two second clamping pieces 424 respectively, the retaining member 40 clamps the frame 12 and the socket 33 on both sides respectively, effectively restricting the position of the second power terminal 32 relative to the photovoltaic module 10, and preventing the wire 30 from getting tangled to a certain extent. In addition, the retaining member 40 has a simple structure and is easy to manufacture.

[0065] Specifically, the first clip 413 and the second clip 424 are respectively connected to the two sides of the substrate 412 along its own thickness direction and extend outward away from the substrate 412 in opposite directions. The first clip 413 and the second clip 424 both form an angle with the substrate 412. The two first clips 413 are respectively connected to the two ends of the substrate 412 along the first direction, and the two second clips 424 are respectively connected to the two ends of the substrate 412 along the first direction and located on opposite sides of the first clips 413, thereby forming a first retaining groove 411 and a second retaining groove 422 on both sides of the substrate 412 in the thickness direction.

[0066] Optionally, the inner contour of the second retaining groove 422 matches the shape and size of the socket 33. For example, the socket 33 has rounded corners around its perimeter, and the second retaining groove 422 has rounded curved surfaces at its corners so that the groove wall of the second retaining groove 422 fits against the outer surface of the socket 33. Alternatively, the cross-sectional dimensions of the second retaining groove 422 match the cross-sectional dimensions of the socket 33. Since the cross-sectional dimensions of the socket 33 are larger than the cross-sectional dimensions of the support rod 121 of the frame 12, the cross-sectional dimensions of the second retaining groove 422 are also larger than the cross-sectional dimensions of the first retaining groove 411.

[0067] Optionally, along the first direction, the relative distance between the two first clips 413 is less than the relative distance between the two second clips 424, so that the space inside the second retaining groove 422 is greater than the space inside the first retaining groove 411, thus being sufficient to accommodate the relatively large socket 33.

[0068] Optionally, the retaining member 40 is provided with a reinforcing rib 44, which is triangular in shape. One side of the reinforcing rib 44 is connected to the surface of the first clamping piece 413 and faces away from the surface of the other first clamping piece 413 in a first direction. The other side of the reinforcing rib 44 is connected to the second clamping piece 424 and / or the bottom piece 412. In this way, the structural strength of the retaining member 40 is improved by the reinforcing rib 44.

[0069] Please see Figure 4In some embodiments, a first slot 414 is formed between the ends of the two first clips 413 that are away from the base plate 412, and a second slot 425 is formed between the ends of the two second clips 424 that are away from the base plate 412. The first slot 414 and the second slot 425 are opposite to each other along a second direction (Y direction as shown in the figure), and the second direction is perpendicular to the first direction.

[0070] Thus, by having the first slot 414 and the second slot 425 facing away from each other in the second direction, the wire 30 is fixed by the socket 33 to the outside of the frame 12 facing away from the photovoltaic panel 11 in the second direction, thereby reducing the interference between the wire 30 and the photovoltaic panel 11.

[0071] Specifically, the first retaining groove 411 and the second retaining groove 422 respectively form a first groove 414 and a second groove 425 facing away from each other. The first groove 414 and the second groove 425 are respectively located on both sides of the substrate 412 and are directly opposite to the substrate 412 along the second direction. Figure 2 The second direction is parallel to the extension direction of the photovoltaic panel 11. The first slot 414 faces the photovoltaic panel 11, and the second slot 425 faces away from the photovoltaic panel 11. That is, the retaining member 40 clamps the socket 33 and the frame 12 on both sides along the extension direction of the photovoltaic panel 11, so that the socket 33 is close to the frame 12 and does not easily interfere with the photovoltaic module 10.

[0072] Optionally, in some embodiments, the end of the first clip 413 away from the base plate 412 is formed with a protruding edge 4131, and a first slot 414 is formed between the two protruding edges 4131. The protruding edge 4131 protrudes towards the other first clip 413 and the first clip 413 in which it is located, so that the first slot 414 is narrowed relative to the slot space of the first holding slot 411, and the protruding edge 4131 and the base plate 412 together hold the frame 12 in the second direction, thereby strengthening the limiting function of the first clamping part 41.

[0073] Please see Figure 4 In some embodiments, the side of the second clip 424 away from the base plate 412 forms an arc-shaped end 4241, the curvature of which matches the curvature of the outer peripheral surface of the socket 33.

[0074] Thus, the side of the second clip 424 away from the base plate 412 forms an arc-shaped end 4241 that matches the outer peripheral surface of the socket 33, thereby enhancing the clamping stability of the second clip 424 on the socket 33 and preventing the socket 33 from slipping out of the second retaining groove 422.

[0075] Specifically, the socket 33 is roughly cylindrical, with a roughly square cross-section and rounded corners. The opposing surfaces of the second clip 424 are in contact with the outer periphery of the socket 33, and both the side of the second clip 424 connected to the base plate 412 and the side away from the base plate 412 form arc surfaces that match the rounded corners of the socket 33.

[0076] The distance between the two arc-shaped ends 4241 along the first direction is less than the distance between the middle sections of the two second clips 424 on the two side arc surfaces. A second slot 425 is formed between the two arc-shaped ends 4241, that is, the second slot 425 formed by the two arc-shaped ends 4241 is closed relative to the space inside the slot. The arc-shaped ends 4241 and the bottom plate 412 can restrict the movement of the socket 33 in the second direction, thereby effectively preventing the socket 33 from slipping out of the second slot 425.

[0077] In some implementations, along the first direction, two first clips 413 clamp the frame 12 from the top and bottom, respectively, and two second clips 424 clamp the socket 33 from the top and bottom, respectively, jointly restricting the degree of freedom of movement of the wire 30 relative to the photovoltaic module 10 at the second power connection end 32 in the first direction. Along the second direction, two protruding edges 4131 engage with the frame 12, forming a narrower first slot 414 opposite to the bottom plate 412, jointly restricting the degree of freedom of movement of the retaining member 40 relative to the photovoltaic module 10 in the second direction; two arc-shaped ends 4241 form a converging second slot 425 opposite to the bottom edge along the second direction, jointly restricting the degree of freedom of movement of the socket 33 relative to the retaining member 40 in the second direction. Combined with the limiting effect of the retaining member 40 in the first and second directions, the wire 30 is effectively prevented from winding onto the photovoltaic module 10, and the wire 30 has a certain length variation margin in the third direction.

[0078] Please see Figure 3 and Figure 4 In some embodiments, the second clamping part 42 is formed with a second retaining groove 422, the socket 33 is at least partially accommodated in the second retaining groove 422, the outer surface of the socket 33 is formed with a limiting structure 331, the groove wall of the second retaining groove 422 is formed with a limiting part 423 that cooperates with the limiting structure 331, one of the limiting structure 331 and the limiting part 423 is a protrusion, and the other is a groove, the protrusion is at least partially accommodated in the groove.

[0079] Thus, the socket 33 is at least partially accommodated in the second retaining groove 422, and the outer surface of the socket 33 and the groove wall of the second retaining groove 422 are engaged and connected by the limiting structure 331 and the limiting part 423, thereby achieving the effect of fixing the socket 33 in the second retaining groove 422.

[0080] Specifically, in some embodiments, the limiting structure 331 is a protrusion, and the limiting portion 423 is a groove; conversely, in other embodiments, the limiting structure 331 is a groove, and the limiting portion 423 is a protrusion. The limiting structure 331 can be provided on the surface of the socket 33 opposite to the groove wall of the second retaining groove 422. Correspondingly, the limiting portion 423 is formed at the position where the groove wall of the second retaining groove 422 is opposite to the limiting structure 331. This application does not limit the shape, size, and number of protrusions and grooves. For example, to avoid increasing the volume and weight of the socket 33, the limiting structure 331 is a groove, which can be a shallow, strip-shaped groove; correspondingly, the limiting portion 423 is a protrusion, which is a strip-shaped vertical rib with a relatively low height.

[0081] Please see Figure 4 In some embodiments, the limiting structure 331 is a groove and the limiting part 423 is a protrusion. The groove is formed on the side surface of the socket 33 facing the frame 12, and the protrusion protrudes from the groove wall of the second holding groove 422 facing away from the frame 12.

[0082] Thus, the limiting structure 331 is a groove formed on the side of the socket 33 facing the frame 12, and the limiting part 423 is a protrusion formed on the groove wall of the second holding groove 422 facing away from the frame 12, so that the second clamping part 42 abuts against the side of the frame 12 and engages, which is conducive to stable engagement and thus plays a good limiting role for the socket 33.

[0083] Specifically, a groove is formed on the surface of the socket 33 facing the base plate 412, and a protrusion protrudes from the surface of the base plate 412 that forms the second retaining groove 422. In the second direction, which is the thickness direction of the base plate 412, a portion of the groove wall of the second retaining groove 422 is formed on the surface of the base plate 412 and the second clamping piece 424 on the same side. A limiting part 423 can be formed at a position opposite to the limiting structure 331 on the base plate 412. The second clamping part 42 clamps the socket 33, and a portion of the outer peripheral surface of the socket 33 fits against the groove wall of the second retaining groove 422. The protrusion extends into the groove, further restricting the freedom of movement of the socket 33 within the second retaining groove 422.

[0084] Please see Figure 2 and Figure 4 In some embodiments, the second retaining groove 422 is formed with two second openings 426 opposite each other along a third direction, and the socket 33 passes through the two second openings 426, with the third direction parallel to the length direction of the side of the frame.

[0085] In this way, the socket 33 can be inserted into or removed from the second retaining slot 422 along the length of the side of the frame 12. During the installation and removal process, the socket 33 is less likely to interfere with the frame 12, which improves the ease of use of the retaining member 40.

[0086] In some embodiments, the first direction is the Z direction as shown in the figure, the second direction is the Y direction as shown in the figure, and the third direction is the X direction as shown in the figure. The first direction, the second direction, and the third direction are perpendicular to each other.

[0087] Specifically, the second opening 426 is used to accommodate the socket 33 being inserted into the second retaining slot 422 in a third direction.

[0088] Please see Figures 2-4 In some embodiments, the protrusions and grooves extend along a third direction, and the distance by which the protrusions and grooves extend along the third direction is less than the dimension of the socket 33 in the third direction.

[0089] Thus, by means of the protrusions and grooves along the third direction, it is easy for the socket 33 to be inserted into the second retaining groove 422 along the third direction, and the distances of the protrusions and grooves along the third direction are all less than the dimensions of the socket 33 in the third direction, thereby preventing the socket 33 from slipping out.

[0090] Specifically, in the third direction, that is, the opposite direction of the two second openings 426, the socket 33 passes through the second opening 426 to be partially accommodated in the second retaining groove 422. During the process of the socket 33 being inserted into the second retaining groove 422 in the third direction, the protrusion engages with the groove.

[0091] For example, the limiting structure 331 is a groove formed on the side surface of the socket 33 facing the base plate 412, and the limiting part 423 is a protrusion formed on the base plate 412. One end of the groove is closed along the third direction, and the other end is open. The groove wall at the opening is inclined along the third direction so that the protrusion can enter the groove from the opening along the third direction, and after entering the groove, the protrusion can abut against the closed end of the groove, thereby achieving the limiting effect.

[0092] Please see Figure 5 In some embodiments, the socket 33 and the second clamping part 42 are an integral structure.

[0093] Thus, by connecting the socket 33 to the second clamping part 42 as an integral structure, the wire 30 is fixed relative to the second power receiving end 32 and the clamping member 40, thereby restricting the freedom of movement of the wire 30 and preventing the wire 30 from getting tangled on the photovoltaic module 10. This design also saves the assembly steps of the socket 33 and the clamping member 40. When fixing the wire 30, it is only necessary to clamp the first clamping part 41 to the frame 12, which further simplifies the operation.

[0094] Specifically, part of the housing of the socket 33 can be integrally formed with the second clamping part 42 and the first clamping part 41. The socket 33 and the second clamping part 42 are connected as one piece. The wire 30 is fixedly connected to the retaining member 40 through the socket 33. The retaining member 40 is clamped to the side of the frame 12 through the first clamping part 41, thereby restricting the position of the wire 30 to the outside of the photovoltaic panel 11, achieving the effect of preventing the wire 30 from getting tangled in the photovoltaic module 10.

[0095] In some embodiments, the photovoltaic device 100 also includes a plug 34, which is located on opposite sides of the junction box 20, along with the socket 33.

[0096] Thus, both the plug 34 and the socket 33 are connected to the junction box 20 via the wire 30. By positioning the plug 34 and the socket 33 on opposite sides of the junction box 20, the tangling of the wire 30 is further prevented.

[0097] Specifically, along the length of the side of the frame 12 held by the retaining member 40, the plug 34 and the socket 33 are located on opposite sides of the junction box 20. The opposite ends of the junction box 20 are respectively connected to two sections of wire 30. One section of wire 30 has a socket 33 at its second electrical terminal 32, which enables the socket 33 to be electrically connected to the photovoltaic panel 11. The other section of wire 30 has a plug 34 at its end away from the junction box 20.
