[0007] In this way, two first openings opposite to each other along the length direction of the side of the frame are formed by the first holding groove, and the frame passes through the two first openings, so that the first holding groove can act as a sliding groove to cooperate with the side of the frame, so that the holding part can drive the socket to slide along the side of the frame on the frame, avoiding damage to components caused by the pulling force of the wire when the photovoltaic module is opened and closed.
[0008] In some embodiments, the first clamping portion includes a bottom sheet and two first clamping sheets opposite to each other along a first direction, the two first clamping sheets are both connected to the bottom sheet, and the first clamping sheets and the bottom sheet together form a first clamping groove.
[0009] In this way, the first clamping groove is formed by the first clip and the bottom film together, covering the side of the frame, effectively limiting the movement of the first clamping part relative to the frame in the first direction and the direction relative to the bottom film and the frame, which is beneficial to limiting the position of the socket relative to the photovoltaic component.
[0010] In some embodiments, a convex edge is formed on a side of the first clip away from the bottom film, and the convex edge is engaged with the frame.
[0011] In this way, a convex edge engaging with the frame is formed on the side of the first clip away from the bottom film, thereby enhancing the clamping stability of the first clip on the frame and preventing the clamping member from slipping off the frame.
[0012] In some embodiments, the second clamping portion includes two second clips opposite to each other along the first direction. The second clips are both connected to the bottom film and located on the side of the bottom film away from the first clip. The second clips and the bottom film together form a second clamping groove.
[0013] In this way, the two first clips and the two second clips are respectively used to form the first clamping groove and the second clamping groove on the opposite sides of the bottom film, so that the two sides of the clamping member respectively clamp the frame and the socket, effectively limiting the position of the second power connection terminal relative to the photovoltaic component and preventing the wires from being entangled to a certain extent. In addition, the structure of the clamping member is simple and easy to manufacture.
[0014] In some embodiments, a first notch is formed between the ends of the two first clips away from the bottom film, and a second notch is formed between the ends of the two second clips away from the bottom film. The first notch and the second notch are opposite to each other along a second direction, and the second direction is perpendicular to the first direction.
[0015] In this way, the first notch and the second notch are opposite to each other along the second direction, so that the wire is fixed to the outer side of the frame along the second direction away from the photovoltaic panel through the socket, thereby reducing interference between the wire and the photovoltaic panel.
[0016] In some embodiments, a side of the second clip away from the bottom plate forms an arc-shaped end portion, and a curvature of the arc-shaped end portion matches a curvature of an outer peripheral surface of the socket.
[0017] In this way, the arc-shaped end portion matching the outer peripheral surface of the socket is formed by the side of the second clip away from the bottom plate, and the second clip clamps the socket stably, preventing the socket from slipping out of the second clamping groove.
[0018] In some embodiments, the second clamping portion is formed with a second clamping groove, the socket is at least partially accommodated in the second clamping groove, the outer surface of the socket is formed with a limiting structure, the groove wall of the second clamping 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, and the protrusion is at least partially accommodated in the groove.
[0019] In this way, the socket is at least partially accommodated in the second holding groove, and the outer surface of the socket and the groove wall of the second holding groove are engaged and connected through the limiting structure and the limiting portion, thereby achieving the effect of fixing the socket in the second holding groove.
[0020] In some embodiments, the limiting structure is a groove, the limiting portion is a protrusion, the groove is formed on a side surface of the socket facing the frame, and the protrusion protrudes from the groove wall of the second holding groove facing away from the frame.
[0021] In this way, the limiting structure is a groove and is formed on the side of the socket facing the frame, and the limiting portion is a protrusion and is formed on the groove wall of the second holding groove facing away from the frame, so that the protrusion and the groove are engaged on the side of the second clamping portion against the frame, which is conducive to stable engagement, thereby playing a good limiting role for the socket.
[0022] In some embodiments, the second retaining groove is formed with two second openings opposite to each other along a third direction, the socket is passed through the two second openings, and the third direction is parallel to the length direction of the side of the frame.
[0023] In this way, the socket can be installed into or removed from the second holding slot along the length direction of the frame. During the installation and removal process, the socket is not likely to interfere with the frame, thereby improving the convenience of using the holding piece.
[0024] In some embodiments, the protrusion and the groove extend along the third direction, and the distances by which the protrusion and the groove extend along the third direction are both smaller than a dimension of the socket in the third direction.
[0025] In this way, the protrusion and the groove are arranged along the third direction, which facilitates the insertion of the socket into the second holding groove along the third direction, and the distance the protrusion and the groove extend along the third direction is smaller than the size of the socket in the third direction, thereby preventing the socket from slipping.

[0042] See also Figure 1 and Figure 2 The photovoltaic device 100 of the embodiment of the present application includes a photovoltaic module 10, a junction box 20, a wire 30 and a clamping member 40, wherein the photovoltaic module 10 includes a photovoltaic panel 11 and a frame 12, and the frame 12 wraps the edge of the photovoltaic panel 11; the junction box 20 is electrically connected to the photovoltaic panel 11; the clamping member 40 includes a first clamping portion 41 and a second clamping portion 42, the first clamping portion 41 is clamped on the frame 12, and the second clamping portion 42 clamps the socket 33.
[0043] The photovoltaic device 100 of the embodiment of the present application is clamped on the frame 12 by the first clamping portion 41 of the clamping member 40, and the second clamping portion 42 clamps the socket 33, thereby effectively limiting the freedom of movement of the socket 33, preventing the wire 30 from being entangled in the photovoltaic module 10 to a certain extent, and reducing the risk of safety hazards.
[0044] Specifically, the front of the photovoltaic panel 11 faces the light source and converts 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, and the frame 12 is square, resulting in the photovoltaic module 10 having a generally square plate-like structure. A junction box 20 is located on the front of the photovoltaic panel 11 and can be used to store wires 30 for electrical connection.
[0045] In some embodiments, the photovoltaic device 100 further includes a conductor 30, which includes a first power connection end 31 and a second power connection end 32. The first power connection end 31 is connected to the junction box 20, and the second power connection end 32 is provided with a socket 33. The conductor 30 can be an electrical cable, with the first power connection end 31 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 connected to another cable or a plug of an electrical device to output the electrical energy of the photovoltaic panel 11.
[0046] The clamping member 40 is mounted on the frame 12 via a first clamping portion 41. The second clamping portion 42 is fixedly connected to the first clamping portion 41. The first clamping portion 41 and the second clamping portion 42 can be an integral structure. The second clamping portion 42 is positioned away from the frame 12 and the photovoltaic panel 11, so that the socket 33 is fixed to the side of the frame 12 opposite the photovoltaic panel 11 via the second clamping portion 42.
[0047] The second clamping portion 42 clamps the socket 33 and can be fixedly connected to the socket 33. Furthermore, the second clamping portion 42 and the socket 33 can be fixedly connected by at least one of welding, riveting, gluing, snap connection, threaded connection, integral molding, etc. In some embodiments, as Figure 2 As shown, the second clamping portion 42 forms a second clamping groove 42 and is engaged with the socket 33. In other embodiments, such as Figure 5 As shown, the second clamping portion 42 and the socket 33 are an integral structure.
[0048] See also Figure 2 、 Figure 4 and Figure 5 In some embodiments, the first clamping portion 41 is formed with a first clamping groove 411, and a portion of the frame 12 is accommodated in the first clamping groove 411. The first clamping groove 411 is formed with two first openings 415 opposite to each other along the length direction of the side of the frame 12 (the X direction as shown in the figure), and the frame 12 passes through the two first openings 415.
[0049] In this way, two first openings 415 opposite to each other along the length direction of the side of the frame 12 are formed through the first holding groove 411, and the frame 12 passes through the two first openings 415, so that the first holding groove 411 can slide along the side of the frame 12 as a sliding groove, so that the holding member 40 can drive the socket 33 to slide along the side of the frame 12, thereby avoiding damage to components caused by the pulling force of the wire 30 when the photovoltaic component 10 is opened and closed.
[0050] It should be noted that the photovoltaic device 100 typically utilizes a foldable photovoltaic module 10. When the photovoltaic module 10 is opened or closed, the change in length of the wire 30 generates a certain pulling force. Thus, the first retaining groove 411 forms two first openings 415 facing each other along the third direction. The frame 12 passes through the two first openings 415, allowing the retaining member 40 to drive the socket 33 to slide along the frame 12 along the third direction, thereby preventing damage to components caused by the pulling force of the wire 30.
[0051] Specifically, the first clamping portion 41 and the second clamping portion 42 are arranged flush along the direction of extension of the photovoltaic panel 11. The frame 12 can be formed by connecting a plurality of support rods 121 and connectors 122 end-to-end. The first clamping portion 41 can be clamped onto one of the support rods 121 that make up the frame 12, partially enclosing the rod on the side of the frame 12 facing away from the photovoltaic panel 11. The direction in which the two first openings 145 face each other corresponds to the direction in which the support rod 121 held by the first clamping portion 41 extends.
[0052] A support rod 121 of the frame 12 passes through the two first openings 415, and the clamping member 40 can slide a certain distance along the support rod 121, driving the socket 33 fixedly connected to the second clamping portion 42 to move relative to the frame 12, so that the wire 30 has a certain degree of freedom of movement in the length direction of the side of the frame 12, so that when the length of the wire 30 changes or is pulled, the clamping member 40 can provide a movable margin to avoid damage to components.
[0053] Optionally, the inner contour of the first retaining groove 411 matches the shape and size of the frame 12, so that the frame 12 is stably engaged with the first retaining groove 411. For example, if the frame 12 is square and the support rod 121 is a straight rod with a square cross-section, the first retaining groove 411 is a square groove with a similar cross-sectional shape to the support rod 121 and matches the cross-sectional size of the support rod 121.
[0054] The first clamping groove 411 accommodates a portion of the frame 12, and the second clamping portion 42 is fixedly connected to the socket 33, so that the clamping member 40 is connected to the frame 12 and the socket 33 at the same time, effectively limiting the position of the wire 30 next to the photovoltaic component 10 and preventing the wire 30 from being entangled on the photovoltaic component 10.
[0055] See also Figure 4 In some embodiments, the first clamping portion 41 includes a bottom film 412 and two first clips 413 opposite to each other along a first direction (Z direction as shown in the figure), and the two first clips 413 are both connected to the bottom film 412, and the first clips 413 and the bottom film 412 together form a first clamping groove 411.
[0056] In this way, the first clamping groove 411 is formed by the first clip 413 and the bottom film 412 together, covering the side of the frame 12, effectively limiting the movement of the first clamping portion 41 relative to the frame 12 in the first direction and the direction opposite to the bottom film 412 and the frame 12, thereby facilitating limiting the position of the socket 33 relative to the photovoltaic component 10.
[0057] Specifically, the first clip 413 forms an angle with the bottom film 412, and the two first clips 413 are respectively connected to the two ends of the bottom film 412 along the first direction. The first clip 413 and the bottom film 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 that are opposite to each other along the first direction. The side surface of the bottom film 412 that encloses the first retaining groove 411 is opposite to the side of the support rod 121 that is away from the photovoltaic panel 11. Therefore, the first clamping portion 41 acts as a limit in the first direction and in the direction in which the bottom film 412 is opposite to the frame 12.
[0058] Furthermore, the first clamping piece 413 can form an angle of approximately 90° with the bottom film 412 , the support rod 121 clamped by the first clamping portion 41 has a square cross-section, and the bottom film 412 can face the surface of the clamped support rod 121 away from the photovoltaic panel 11 .
[0059] Furthermore, a portion of the frame 12 is accommodated in the first retaining groove 411 , and the surface of the bottom film 412 surrounding the first retaining groove 411 can abut against the clamped frame 12 .
[0060] See also Figure 2 and Figure 4 In some embodiments, a convex edge 4131 is formed on a side of the first clip 413 away from the bottom film 412 , and the convex edge 4131 is engaged with the frame 12 .
[0061] In this way, a convex edge 4131 engaging with the frame 12 is formed on the side of the first clip 413 away from the bottom film 412 , thereby enhancing the clamping stability of the first clip 413 on the frame 12 and preventing the holding member 40 from slipping off the frame 12 .
[0062] Specifically, the convex edge 4131 forms an angle with the first clip 413 and extends toward the other first clip 413, so that the relative distance between the two convex edges 4131 is narrower than the relative distance between the first clips 413, thereby preventing the frame 12 from escaping from the first notch 414 and the first retaining groove 411. Exemplarily, the first retaining groove 411 is a square groove, and the two first clips 413 are substantially parallel to each other and each form an angle of approximately 90 degrees with the bottom plate 412. The first clips 413 are engaged with the inner edge of the frame 12 via the convex edges 4131.
[0063] See also Figure 4In some embodiments, the second clamping portion 42 includes two second clips 424 opposite to each other along the first direction. The second clips 424 are connected to the bottom film 412 and are located on the side of the bottom film 412 away from the first clip 413. The second clips 424 and the bottom film 412 together form a second clamping groove 422.
[0064] In this way, the two first clips 413 and the two second clips 424 are respectively used to form the first clamping groove 411 and the second clamping groove 422 on the opposite sides of the bottom film 412, so that the two sides of the clamping member 40 respectively clamp the frame 12 and the socket 33, effectively limiting the position of the second power terminal 32 relative to the photovoltaic component 10, and preventing the wire 30 from being entangled to a certain extent. In addition, the structure of the clamping member 40 is simple and easy to manufacture.
[0065] Specifically, the first clip 413 and the second clip 424 are respectively connected to the two side surfaces of the bottom sheet 412 along the thickness direction thereof, and extend outwardly away from the bottom sheet 412 in opposite directions. The first clip 413 and the second clip 424 each form an angle with the bottom sheet 412. The two first clips 413 are respectively connected to the two ends of the bottom sheet 412 along the first direction, and the two second clips 424 are respectively connected to the two ends of the bottom sheet 412 along the first direction and are located on opposite sides of the first clip 413, thereby forming the first retaining groove 411 and the second retaining groove 422 on both sides of the bottom sheet 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, and the second retaining groove 422 forms arc-shaped curved surfaces at the corners, so that the groove wall of the second retaining groove 422 fits the outer surface of the socket 33. For another example, the cross-sectional dimensions of the second retaining groove 422 match the cross-sectional dimensions of the socket 33. Because the cross-sectional dimensions of the socket 33 are larger than the cross-sectional dimensions of the support rods 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 smaller than the relative distance between the two second clips 424, so that the space inside the second clamping groove 422 is larger than the space inside the first clamping groove 411, thereby being sufficient to accommodate a relatively large socket 33.
[0068] Optionally, the clamping member 40 is provided with a reinforcing rib 44. The reinforcing rib 44 is triangular in shape, with one side of the reinforcing rib 44 connected to a surface of the first clip 413 facing away from the other first clip 413 along the first direction, and the other side of the reinforcing rib 44 connected to the second clip 424 and / or the bottom plate 412. In this way, the structural strength of the clamping member 40 is improved by the reinforcing rib 44.
[0069] See also Figure 4In some embodiments, a first slot 414 is formed between the ends of the two first clips 413 away from the bottom film 412, and a second slot 425 is formed between the ends of the two second clips 424 away from the bottom film 412. The first slot 414 and the second slot 425 are opposite to each other along a second direction (the Y direction as shown in the figure), and the second direction is perpendicular to the first direction.
[0070] In this way, the first notch 414 and the second notch 425 are opposite to each other in the second direction, so that the wire 30 is fixed to the outer side of the frame 12 away from the photovoltaic panel 11 in the second direction through the socket 33, reducing interference between the wire 30 and the photovoltaic panel 11.
[0071] Specifically, the first holding slot 411 and the second holding slot 422 form a first notch 414 and a second notch 425 facing each other, respectively. The first notch 414 and the second notch 425 are respectively located on both sides of the bottom film 412 and face the bottom film 412 along the second direction. Figure 2 The second direction is parallel to the extension direction of the photovoltaic panel 11, the first notch 414 faces the photovoltaic panel 11, and the second notch 425 faces away from the photovoltaic panel 11, that is, the clamping member 40 clamps the socket 33 and the frame 12 on both sides of the extension direction of the photovoltaic panel 11, so that the socket 33 is close to the frame 12 and is not easy to interfere with the photovoltaic component 10.
[0072] Optionally, in some embodiments, a convex edge 4131 is formed at the end of the first clip 413 away from the bottom film 412, and a first slot 414 is formed between the two convex edges 4131. The convex edge 4131 protrudes toward 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 space in the first clamping slot 411, and the convex edge 4131 and the bottom film 412 jointly clamp the frame 12 in the second direction, thereby strengthening the limiting effect of the first clamping portion 41.
[0073] See also Figure 4 In some embodiments, a side of the second clip 424 away from the bottom plate 412 forms an arc-shaped end portion 4241 , and a curvature of the arc-shaped end portion 4241 matches a curvature of an outer peripheral surface of the socket 33 .
[0074] In this way, the side of the second clip 424 away from the bottom 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 clamping groove 422.
[0075] Specifically, the socket 33 is generally cylindrical, with a roughly square cross-section and rounded corners. The opposing surfaces of the second clip 424 are in contact with the outer circumference of the socket 33. Both the side of the second clip 424 connected to the bottom plate 412 and the side away from the bottom plate 412 form curved surfaces that match the rounded corners of the socket 33.
[0076] The two arcuate ends 4241 face each other along the first direction, and the distance between them is less than the distance between the two second clips 424 in the middle sections between the two curved surfaces. A second notch 425 is formed between the two arcuate ends 4241. In other words, the second notch 425 formed by the two arcuate ends 4241 is concave relative to the space within the slot. The arcuate ends 4241 and the bottom plate 412 can jointly restrict the movement of the socket 33 in the second direction, thereby effectively preventing the socket 33 from slipping out of the second notch 425.
[0077] In some embodiments, along the first direction, the two first clips 413 clamp the frame 12 from the top and bottom, respectively, and the two second clips 424 clamp the socket 33 from the top and bottom, respectively, to jointly restrict the freedom of movement of the wire 30 at the second power connection end 32 relative to the photovoltaic module 10 in the first direction. Along the second direction, the two raised edges 4131 engage with the frame 12, forming a narrower first notch 414 that faces the bottom edge 412, jointly restricting the freedom of movement of the clamp 40 relative to the photovoltaic module 10 in the second direction. The two curved ends 4241 form a narrowed second notch 425 that faces the bottom edge in the second direction, jointly restricting the freedom of movement of the socket 33 relative to the clamp 40 in the second direction. Combined with the limiting function of the clamp 40 in the first and second directions, the wire 30 is effectively prevented from being entangled with the photovoltaic module 10, and a certain length variation margin is provided for the wire 30 in the third direction.
[0078] See also Figure 3 and Figure 4 In some embodiments, the second clamping portion 42 is formed with a second clamping groove 422, and the socket 33 is at least partially accommodated in the second clamping groove 422. A limiting structure 331 is formed on the outer surface of the socket 33, and a limiting portion 423 is formed on the groove wall of the second clamping groove 422 to cooperate with the limiting structure 331. One of the limiting structure 331 and the limiting portion 423 is a protrusion, and the other is a groove, and the protrusion is at least partially accommodated in the groove.
[0079] In this way, 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 through the limiting structure 331 and the limiting portion 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 surface of the socket 33 opposite to the groove wall of the second retaining groove 422 can be provided with a limiting structure 331. Accordingly, the position where the groove wall of the second retaining groove 422 and the limiting structure 331 are opposite to each other forms the limiting portion 423. The present application does not limit the shape, size, and number of the protrusions and grooves. For example, in order to avoid increasing the volume and weight of the socket 33, the limiting structure 331 is a groove, and the groove can be a shallow strip-shaped groove. Accordingly, the limiting portion 423 is a protrusion, and the protrusion is a vertical strip-shaped rib with a relatively low height.
[0081] See also Figure 4 In some embodiments, the limiting structure 331 is a groove, and the limiting portion 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] In this way, the limiting structure 331 is a groove and is formed on the side of the socket 33 facing the frame 12, and the limiting portion 423 is a protrusion and is formed on the groove wall of the second holding groove 422 facing away from the frame 12, so that the second clamping portion 42 is clamped against one side of the frame 12, which is conducive to stable clamping, thereby playing a good limiting role on the socket 33.
[0083] Specifically, a groove is formed on the side of the socket 33 facing the bottom plate 412, and a protrusion protrudes from the surface of the bottom plate 412, forming a second retaining groove 422. In the second direction, i.e., the thickness direction of the bottom plate 412, the surface of the bottom plate 412 on the same side as the second clamping piece 424 forms a portion of the wall of the second retaining groove 422. The limiting portion 423 can be formed at a position on the bottom plate 412 opposite the limiting structure 331. The second clamping portion 42 clamps the socket 33, with a portion of the outer circumference of the socket 33 abutting against the wall of the second retaining groove 422. The protrusion extends into the groove, further limiting the freedom of movement of the socket 33 within the second retaining groove 422.
[0084] See also Figure 2 and Figure 4 In some embodiments, the second retaining groove 422 is formed with two second openings 426 opposite to each other along a third direction, and the socket 33 is passed through the two second openings 426, and the third direction is parallel to the length direction of the side of the frame.
[0085] In this way, the socket 33 can be installed into or removed from the second holding slot 422 along the length direction of the side of the frame 12. During the installation and removal process, the socket 33 is not easy to interfere with the frame 12, which improves the convenience of using the holding 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 to be inserted into the second holding groove 422 along the third direction.
[0088] See also Figure 2-Figure 4 In some embodiments, the protrusion and the groove extend along the third direction, and the distances by which the protrusion and the groove extend along the third direction are both smaller than the size of the socket 33 in the third direction.
[0089] In this way, the protrusions and grooves are arranged along the third direction, thereby facilitating the insertion of the socket 33 into the second retaining groove 422 along the third direction, and the distances along which the protrusions and grooves extend along the third direction are smaller than the dimensions of the socket 33 in the third direction, thereby preventing the socket 33 from slipping.
[0090] Specifically, the third direction is the direction opposite to the two second openings 426, and the socket 33 passes through the second opening 426 to be partially accommodated in the second holding groove 422. When the socket 33 is inserted into the second holding groove 422 along the third direction, the protrusion is engaged with the groove.
[0091] Illustratively, the limiting structure 331 is a groove formed on the side of the socket 33 facing the bottom plate 412, and the limiting portion 423 is a protrusion formed on the bottom plate 412. Of the two ends of the groove along the third direction, one is closed and the other 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 abut against the closed end of the groove after entering the groove, thereby achieving a limiting effect.
[0092] See also Figure 5 In some embodiments, the socket 33 and the second clamping portion 42 are an integral structure.
[0093] In this way, the socket 33 is connected to the second clamping portion 42 as an integral structure, so that the wire 30 is relatively fixed to the clamping member 40 at the second power connection end 32, thereby limiting the freedom of movement of the wire 30 and preventing the wire 30 from being entangled 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 portion 41 to the frame 12, further simplifying the operation.
[0094] Specifically, a portion of the housing of the socket 33 can be integrally formed with the second clamping portion 42 and the first clamping portion 41. The socket 33 and the second clamping portion 42 are connected as one body, and the wire 30 is fixedly connected to the clamping member 40 via the socket 33. The clamping member 40 is clamped to the side of the frame 12 via the first clamping portion 41. Thus, the clamping member 40 restricts the position of the wire 30 to the outside of the photovoltaic panel 11, thereby preventing the wire 30 from being entangled with the photovoltaic module 10.
[0095] In some embodiments, the photovoltaic device 100 further includes a plug 34 , and the plug 34 and the socket 33 are located on opposite sides of the junction box 20 .
[0096] In this way, the plug 34 and the socket 33 are both connected to the junction box 20 through the wires 30 , and the plug 34 and the socket 33 are disposed on opposite sides of the junction box 20 , thereby further preventing the wires 30 from being entangled.
[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 connected to two wires 30. The second power connection end 32 of one wire 30 is provided with a socket 33, which electrically connects the socket 33 to the photovoltaic panel 11. The other wire 30 is provided with a plug 34 at the end away from the junction box 20.
