Description

Technical Field

[0001] The utility model generally relates to a connector, and more specifically to a connector for a photovoltaic panel frame. Background Art

[0002] At present, the frames used for photovoltaic panels include metal frames and non-metal frames. A metal frame usually includes four long strips of profiles, which are connected to each other to form a rectangular frame, wherein two adjacent profiles can be connected to each other through corner connectors. Metal frames include aluminum frames and steel frames. At present, aluminum frames are most widely used in the photovoltaic industry due to their many advantages. However, as the photovoltaic industry's demand for cost reduction becomes higher and higher, steel frames with cost advantages are beginning to be paid more and more attention and used.

[0003] At present, the corner connectors for metal frames are usually made of aluminum. The aluminum corner connector is usually formed by an extrusion process and includes two connecting sections, which are, for example, respectively interference-fitted in the hollow chambers of two adjacent profiles, so that the two adjacent profiles are connected to each other through the corner connector. However, this aluminum corner connector is prone to electrochemical corrosion due to the potential difference between it and the steel profile, and is therefore not well suited for steel frames. In addition, since the aluminum corner connector is formed by an extrusion process, it often has a complex cross-section, and therefore, it is difficult to directly manufacture a corner connector with a structure similar to that of the existing aluminum corner connector using steel. Therefore, it is still challenging to develop a corner connector suitable for steel frames. Utility Model Content

[0040] Reference Figure 1 , Figure 5 and Figure 7 The connector 100 according to the exemplary embodiment of the present utility model can be used for assembling the frame of the photovoltaic panel, more specifically, for connecting the two adjacent sides of the frame, that is, two adjacent profiles 200. In the illustrated embodiment, the connector 100 includes two connecting sections 102 and a transition section 104, and the two connecting sections 102 extend substantially perpendicularly to each other and are connected by the transition section 104. Each of the two connecting sections 102 is suitable for being inserted into the hollow chamber 202 of the corresponding profile 200 and connected to the profile 200. In this way, the connector 100 can realize the connection of two adjacent profiles 200 of the frame of the photovoltaic panel.

[0041] It is understood that in other embodiments, the two connecting sections may also be at other suitable angles to each other, for example, the two connecting sections may be at an acute angle, an obtuse angle or 180° to each other; in other embodiments, the connector may include more than two connecting sections to achieve connection between more than two profiles, and these connecting sections may be connected to each other through a transition section. Optionally, the connector 100 may be made of steel (e.g., spring steel). Optionally, the connector 100 may be integrally formed from a steel plate / sheet by stamping.

[0042] In this document, the hollow chamber 202 of the profile 200 refers to the hollow portion of the profile 200 for receiving the connecting section 102 of the connector 100. In the illustrated embodiment, the profile 200 for the photovoltaic panel frame has a hollow tubular shape and has a substantially L-shaped cross-section. The hollow chamber 202 of the profile 200 is defined by a first wall portion 204, a second wall portion 206, a third wall portion 208, and a fourth wall portion 210 of the profile 200, which may also be collectively referred to as wall portions hereinafter. The first wall portion 204 and the third wall portion 208 are opposite to each other, and the second wall portion 206 and the fourth wall portion 210 are opposite to each other. The inner surface 212 of the hollow chamber 202 is formed by the inner surface of the first wall portion 204, the inner surface of the second wall portion 206, the inner surface of the third wall portion 208, and the inner surface of the fourth wall portion 210. In the illustrated embodiment, the hollow chamber 202 of the profile 200 penetrates the profile 200 along the longitudinal direction of the profile 200. It can be understood that in some other embodiments, the hollow chamber of the profile may not penetrate the profile, but is only provided in a local area of ​​the profile for receiving a connecting section of a connecting piece.

[0043] Reference Figures 1 to 5 as well as Figure 7 , the two connecting sections 102 of the connecting member 100 may have the same or similar structure. In the illustrated embodiment, the two connecting sections 102 of the connecting member 100 have similar structures. The following will mainly describe one of the connecting sections 102.

[0044] The connecting section 102 is suitable for being inserted into the hollow chamber 202 of the profile 200 along the insertion direction I and connected to the profile 200. The connecting section 102 includes a base plate 108 having a window 106 and an anchoring arm 110 extending from the base plate 108 toward a first side S1 of the base plate 108 and extending through the window 106 to a second side S2 of the base plate 108 opposite to the first side S1. The anchoring arm 110 includes a first anchoring portion 112 located at the second side S2. The first anchoring portion 112 is suitable for mechanically interfering with a first stop portion 214 on the profile 200 when the connecting section 102 is inserted into the hollow chamber 202 of the profile 200, so as to limit the movement of the connecting section 102 relative to the profile 200 (particularly, limit the movement of the connecting section 102 relative to the profile 200 in a direction opposite to the insertion direction I), thereby preventing the connecting section 102 from being separated from the hollow chamber 202 of the profile 200.

[0045] In the illustrated embodiment, the first anchoring portion 112 is in the form of a convex rib, and the first stop portion 214 is in the form of a slot. During the insertion of the connecting section 102 into the hollow chamber 202 of the profile 200, the anchoring arm 110 can be elastically deformed due to the mechanical interference between the first anchoring portion 112 and the first wall portion 204 of the profile 200, so that the first anchoring portion 112 moves toward the first side S1 of the substrate 108 so that the connecting section 102 enters the hollow chamber 202. The anchoring arm 110 extends from the substrate 108 first toward the first side S1 of the substrate 108 and then toward the second side S2 of the substrate 108, so that the anchoring arm 110 has a curved structure, which increases the elasticity of the anchoring arm 110 and can reduce the insertion force required for the connecting section 102 to be inserted into the hollow chamber 202. When the connecting section 102 is inserted into the hollow chamber 202 of the profile 200 (i.e., the window 106 of the connecting section 102 is aligned with the first limit portion 214 of the profile 200, or, in other words, the first anchoring portion 112 of the connecting section 102 is aligned with the first limit portion 214 of the profile 200), the anchoring arm 110 can restore its deformation, and the first anchoring portion 112 can engage with the first limit portion 214 of the profile 200 (in other words, the first anchoring portion 112 can mechanically interfere with the inner edge of the first limit portion 214) to prevent the connecting section 102 from detaching from the hollow chamber 202 of the profile 200, thereby helping to firmly connect the connector 100 and the profile 200 to each other.

[0046] Reference Figures 1 to 5 as well as Figure 7In the illustrated embodiment, the base plate 108 of the connecting section 102 has a generally rectangular shape. The base plate 108 has a first edge 114 and a second edge 116 extending generally along the insertion direction I, and the first edge 114 and the second edge 116 are configured as flanges to enhance the rigidity of the base plate 108, thereby reducing or avoiding undesired deformation of the base plate 108. The base plate 108 includes a first end 118 and a second end 120 opposite to each other in the insertion direction I, wherein the first end 118 is away from the transition section 104, and the second end 120 is adjacent to the transition section 104. During the insertion of the connecting section 102 into the hollow chamber 202, the first end 118 of the base plate 108 will first enter the hollow chamber 202.

[0047] In the illustrated embodiment, the anchoring arm 110 extends from the first end 118 of the base plate 108 toward the second end 120, and sequentially includes a first arm portion 122 bent from the first end 118 toward the first side S1 of the base plate 108, a second arm portion 124 extending from the first arm portion 122 toward the base plate 108, and two third arm portions 126 extending from the second arm portion 124 substantially perpendicular to the base plate 108 and extending through the window 106 to the second side S2 of the base plate 108. A first anchoring portion 112 is provided at the free end of each of the two third arm portions 126, and accordingly, the base plate 108 includes two windows 106 for the two third arm portions 126 to pass through respectively, and the first wall portion 204 of the profile 200 is provided with two first stop portions 214 for respectively engaging with the two first anchoring portions 112. It can be understood that in other embodiments, the anchoring arm may also include other suitable numbers of first anchoring portions, and accordingly, the base may include other suitable numbers of windows, and the profile may include other suitable numbers of first stop portions.

[0048] Reference Figure 1 , Figure 3 , Figure 4 as well as Figure 7 The substrate 108 may also be provided with a reinforcing rib 128 to improve the rigidity of the substrate 108. In the illustrated embodiment, the reinforcing rib 128 is provided between the first end 118 of the substrate 108 and the window 106. It is understood that the reinforcing rib may also be provided at other positions of the substrate.

[0049] In the illustrated embodiment, each first anchoring portion 112 has a guiding edge 130 inclined relative to the insertion direction I, and the guiding edge 130 mechanically interferes with the first wall portion 204 of the profile 200 during the process of inserting the connecting segment 102 into the hollow chamber 202 of the profile 200 to guide the anchoring arm 110 to elastically deform toward the first side S1 of the substrate 108, thereby causing the first anchoring portion 112 to move toward the first side S1 of the substrate 108 to allow the connecting segment 102 to be smoothly inserted into the hollow chamber 202 of the profile 200.

[0050] In the illustrated embodiment, each first anchoring portion 112 has a substantially triangular sheet shape. Each first stop portion 214 of the profile 200 may be in the form of an elongated slot. In the illustrated embodiment, the engagement of the first anchoring portion 112 with the first stop portion 214 may limit the movement of the connecting section 102 relative to the profile 200 in a direction opposite to the insertion direction I, and may also limit the movement of the connecting section 102 relative to the profile 200 in a direction substantially perpendicular to the extension plane of the first anchoring portion 112.

[0051] Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 The connecting section 102 further includes an anchoring wing 132 extending from the base plate 108 toward the first side S1. The anchoring wing 132 is elastically deformable and includes a second anchoring portion 134 located on the first side S1. The second anchoring portion 134 is suitable for mechanically interfering with the second limiting portion 216 on the profile 200 when the connecting section 102 is inserted into the hollow chamber 202 of the profile 200, so as to limit the movement of the connecting section 102 relative to the profile 200 in a direction opposite to the insertion direction I. By providing a first anchoring portion 112 located on the second side S2 of the substrate 108 and a second anchoring portion 134 located on the first side S1 of the substrate 108, when the connector 100 and the profile 200 are connected but tend to separate from each other due to external force, the connection section 102 of the connector 100 can be uniformly stressed on both sides of the substrate 108 through the engagement / mechanical interference between the first anchoring portion 112 and the first limiting portion 214 and the mechanical interference between the second anchoring portion 134 and the second limiting portion 216, thereby avoiding structural damage that may occur when the connection section 102 is stressed on only one side.

[0052] In the illustrated embodiment, the anchoring wing 132 is disposed at the second end 120 of the substrate 108, and sequentially includes a first wing portion 136 bent from the first edge 114 toward the first side S1 of the substrate 108 and a second wing portion 138 extending from the first wing portion 136 substantially parallel to the substrate 108. The second wing portion 138 is in a substantially rectangular sheet shape. The second anchoring portion 134 is disposed at the second wing portion 138. In the illustrated embodiment, the second stopper 216 of the profile 200 is in the form of a convex portion and is disposed on the third wall portion 208 of the profile 200. The second stopper 216 protrudes toward the hollow chamber 202 of the profile 200. When the connector 100 and the profile 200 are connected but tend to separate from each other due to external force, the second limiting portion 216 of the profile 200 can abut the second anchoring portion 134 of the connector 100, or in other words, stop the second anchoring portion 134 of the connector 100 to prevent the connecting section 102 of the connector 100 from detaching from the hollow chamber 202 of the profile 200.

[0053] In the illustrated embodiment, the anchoring wing 132 further includes an avoidance recess 140. The avoidance recess 140 is recessed relative to the second anchoring portion 134, and the avoidance recess 140 is adjacent to the second anchoring portion 134 in the insertion direction I. Specifically, the avoidance recess 140 is closer to the first end 118 of the substrate 108 than the second anchoring portion 134 in the insertion direction I. In this way, when the connecting section 102 of the connector 100 is inserted into the hollow chamber 202 of the profile 200, compared with the second anchoring portion 134 of the anchoring wing 132, the avoidance recess 140 of the anchoring wing 132 will first pass through and avoid the second limiting portion 216 of the profile 200, so as to allow the connecting section 102 to be inserted into the hollow chamber 202 of the profile 200 with a relatively small insertion force; then, as the connecting section 102 is further inserted, the second anchoring portion 134 of the anchoring wing 132 will contact the profile 200. 00 and mechanically interfere with the second limiting portion 216, so that the anchoring wing 132 is elastically deformed toward the substrate 108, thereby allowing the second anchoring portion 134 to move over the second limiting portion 216; after the second anchoring portion 134 moves over the second limiting portion 216, the anchoring wing 132 will recover its deformation, and the second limiting portion 216 of the profile 200 will stop the second anchoring portion 134, so as to prevent the connecting section 102 of the connector 100 from escaping from the hollow chamber 202 of the profile 200. In addition, on the other hand, by providing the avoidance recess 140, the rigidity and bearing capacity of the anchoring wing 132 can be increased, thereby improving the connection strength between the connecting section 102 and the profile 200, without significantly increasing the insertion force required for inserting the connecting section 102 into the hollow chamber 202.

[0054] In the illustrated embodiment, a through hole 142 is provided at the connection between the anchoring wing 132 and the substrate 108 (ie, at the first wing portion 136 of the anchoring wing 132). Figure 4 ) to increase the elasticity of the anchoring wing 132 so that the second anchoring portion 134 can relatively easily move over the second limiting portion 216 of the profile 200 during the process of inserting the connecting section 102 of the connecting piece 100 into the hollow chamber 202 of the profile 200.

[0055] In the illustrated embodiment, the outer contour of the anchoring wing 132 may also have a shape that matches the inner surface 212 of the hollow chamber 202, so that the anchoring wing 132 cooperates with the inner surface 212 of the hollow chamber 202 when the connecting section 102 is inserted into the hollow chamber 202 of the profile 200, so as to limit the movement of the connecting section 102 relative to the profile 200 (in particular, to limit the movement of the connecting section 102 relative to the profile 200 in a lateral direction perpendicular to the insertion direction I), thereby helping to stably maintain the connecting section 102 in the hollow chamber 202 of the profile 200.

[0056] Reference Figures 1 to 5 as well as Figure 7 The connecting section 102 may further include at least one retaining wing 144, 146, and the at least one retaining wing 144, 146 is suitable for abutting against the inner surface 212 of the hollow chamber 202 when the connecting section 102 is inserted into the hollow chamber 202 of the profile 200 to limit the movement of the connecting section 102 relative to the profile 200, so that the connecting section 102 can be stably maintained in the hollow chamber 202 of the profile 200.

[0057] At least one retaining wing may include a first retaining wing 144 extending from the base plate 108 and a second retaining wing 146 extending from the anchoring arm 110, and the first retaining wing 144 and the second retaining wing 146 are configured to respectively abut against two opposite surface portions of the inner surface 212 of the hollow chamber 202. In the illustrated embodiment, the first retaining wing 144 is disposed near the second end 120 of the base plate 108 and is adapted to abut against the inner surface of the first wall portion 204 of the profile 200; the second retaining wing 146 extends from the second arm portion 124 of the anchoring arm 110 in a direction away from the base plate 108 and is adapted to abut against the inner surface of the third wall portion 208 of the profile 200. In the illustrated embodiment, the first retaining wing 144 and the second retaining wing 146 are respectively provided with a first opening 148 and a second opening 150 to increase the elasticity of the first retaining wing 144 and the second retaining wing 146, respectively. During the process of inserting the connecting section 102 into the hollow chamber 202 of the profile 200, the first retaining wing 144 and the second retaining wing 146 can be elastically deformed toward the substrate 108 respectively due to mechanical interference with the profile 200 to allow the connecting section 102 to smoothly enter the hollow chamber 202, and elastically abut the inner surface 212 of the hollow chamber 202 when the connecting section 102 is inserted into the hollow chamber 202. On the one hand, the abutment between the first retaining wing 144 and the second retaining wing 146 and the inner surface 212 of the hollow chamber 202 can limit the relative movement of the connecting section 102 relative to the profile 200 in a direction substantially perpendicular to the substrate 108. On the other hand, the abutment between the first retaining wing 144 and the second retaining wing 146 and the inner surface 212 of the hollow chamber 202 can also increase the friction between the first retaining wing 144 and the second retaining wing 146 and the inner surface 212 of the hollow chamber 202, thereby limiting the movement of the connecting section 102 relative to the profile 200 in a direction substantially parallel to the substrate 108. In other words, by providing the first retaining wing 144 and the second retaining wing 146, the movement of the connecting section 102 relative to the profile 200 in multiple directions can be limited, thereby stably maintaining the connecting section 102 in the hollow chamber 202 of the profile 200.

[0058] Reference Figure 1 , Figure 2 as well as Figure 8, the connection section 102 may include a guide lug 152 extending from the base plate 108 toward the first side S1, and the guide lug 152 is suitable for cooperating with the inner surface 212 of the hollow chamber 202 to guide the connection section 102 to be inserted into the hollow chamber 202 of the profile 200. The guide lug 152 may have a substantially L-shaped cross section to respectively cooperate with two adjacent surface portions of the inner surface 212 of the hollow chamber 202. The guide lug 152 with an L-shaped cross section can more smoothly guide the connection section 102 of the connector 100 to be inserted into the hollow chamber 202 of the profile 200 by cooperating with two mutually adjacent and angled surface portions of the inner surface 212 at the same time, thereby improving the stability and efficiency of installation. The guide lug 152 can also cooperate with the inner surface 212 of the hollow chamber 202 when the connection section 102 is inserted into the hollow chamber 202 of the profile 200 to limit the movement of the connection section 102 relative to the profile 200 (especially limit the movement of the connection section 102 relative to the profile 200 in the transverse direction perpendicular to the insertion direction I), thereby stably maintaining the connection section 102 in the hollow chamber 202 of the profile 200. In the illustrated embodiment, the guide lug 152 is disposed at the second end 120 of the base plate 108 and extends from the second edge 116 of the base plate 108 toward the first side S1, and the guide lug 152 can respectively cooperate / fit with the inner surface of the third wall portion 208 and the inner surface of the fourth wall portion 210. In the illustrated embodiment, the guide lug 152 and the anchoring wing 132 are substantially aligned in a direction perpendicular to the insertion direction I and extend toward each other.

[0059] Return to reference Figure 1 In the illustrated embodiment, the two connecting sections 102 of the connecting member 100 have similar structures, and the only difference is that the orientation of the reinforcing ribs is different. It is understandable that in other embodiments, the two connecting sections of the connecting member may have the same structure. FIG. 6A to FIG. 6B When using the connector 100 to connect two profiles 200, one connecting section 102 of the connector 100 can be first inserted into the hollow chamber 202 of one profile 200 and inserted into place to complete the connection between the connecting section 102 and the profile 200, and then the other connecting section 102 of the connector 100 can be inserted into the hollow chamber 202 of another profile 200 and inserted into place to complete the connection between the connecting section 102 and the profile 200. In this way, the connection between the two profiles 200 can be achieved through simple operations.

[0060] Figures 9 to 13 The connecting piece according to the second embodiment of the utility model is shown. The connecting piece according to the second embodiment is mainly different from the connecting piece according to the first embodiment in the structure of the first anchoring portion. The differences between the two embodiments will be introduced below, and the similarities will not be repeated.

[0061] Reference Figures 9 to 13 The first anchoring portion 112 of the connector 100 according to the second embodiment is in the form of a convex rib and has a substantially L-shaped cross section. The first anchoring portion 112 includes a first section 113 and a second section 115 adjacent to each other. The first section 113 extends substantially perpendicular to the insertion direction I, and the second section 115 extends substantially parallel to the insertion direction I.

[0062] In the illustrated embodiment, the first stopper 214 is in the form of a convex portion and protrudes toward the hollow chamber 202 of the profile 200. During the insertion of the connecting section 102 into the hollow chamber 202 of the profile 200, the anchoring arm 110 can be elastically deformed due to the mechanical interference between the first anchoring portion 112 and the first wall portion 204 of the profile 200, so that the connecting section 102 enters the hollow chamber 202. When the connecting section 102 is inserted into the hollow chamber 202 (e.g., Fig. 12A and Fig. 12B As shown in FIG. 2 , the first anchoring portion 112 of the connecting segment 102 moves over the first limiting portion 214 of the profile 200. At this time, the first anchoring portion 112 can mechanically interfere with the first limiting portion 214, and more specifically, the first segment 113 of the first anchoring portion 112 can mechanically interfere with the first limiting portion 214 to limit the movement of the connecting segment 102 relative to the profile 200 in the direction opposite to the insertion direction I, thereby preventing the connecting segment 102 from being separated from the hollow chamber 202 of the profile 200.
