[0002] When installing a photovoltaic system, the frame of the photovoltaic module needs to be grounded to prevent static electricity from damaging the components. At present, in order to achieve the grounding of the frame of the photovoltaic module, wires are usually fixed to the frame of the photovoltaic module using screws or bolts, and multiple photovoltaic module frames are connected to each other using wires, and finally connected to the grounding device, so as to conduct away the static electricity on the frame of the photovoltaic module.

[0003] Figure 1 A cross-sectional view of a common photovoltaic module frame E is shown. Fastening holes for connecting wires can be provided on the flange F of the photovoltaic module frame, but drilling holes in the photovoltaic module frame will reduce the overall strength of the frame. In addition, with the increasing demand for lightweight photovoltaic systems, photovoltaic module frames with simpler structures and no flanges have appeared. It is inconvenient to provide fastening holes in such photovoltaic module frames themselves, and fastening holes for connecting wires can be provided by accessories provided on the frame. Screws or bolts can be passed through the ring terminals of the wires and the fastening holes on the frame or frame accessories and tightened to connect the wires to the photovoltaic module frame to achieve grounding of the photovoltaic module frame.

[0004] Generally, when installing a photovoltaic system, it is necessary to fix the wires at multiple locations and tighten a large number of screws or bolts, which makes the installation of the photovoltaic system take a long time. Utility Model Content

[0066] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the present utility model, unless otherwise expressly provided, the terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0067] Figures 2A to 3C The clamp 100 for the photovoltaic component 1 according to the first embodiment of the present invention is shown. The clamp 100 and the wire 200 can form a clamp assembly 10 for the photovoltaic component 1.

[0068] Reference Figures 2A to 3C The clip 100 includes a clip body 102, at least one contact portion 104, and a grounding connection portion 106. The clip body 102 is suitable for clamping on the frame 20 of the photovoltaic component 1. The at least one contact portion 104 protrudes from the clip body 102 toward the inside of the clip body 102 and is suitable for abutting against the frame 20. The grounding connection portion 106 is connected to the clip body 102 and is suitable for clamping with the wire 200.

[0069] The clip 100 can be self-fixed on the frame 20 of the photovoltaic module 1 by means of the clip body 102. Compared with the prior art, the clip 100 does not need to punch holes in the frame 20 of the photovoltaic module 1 when it is installed, does not reduce the mechanical strength of the frame 20 of the photovoltaic module 1, and the installation operation of the clip 100 is simple.

[0070] The clip 100 can be integrally formed from a metal sheet by stamping. Optionally, the clip 100 can be made of spring steel to give the clip 100 a certain elasticity.

[0071] In the illustrated embodiment, the clip body 102 is U-shaped and includes a base 108 and a first clamping portion 110a and a second clamping portion 110b disposed on opposite sides of the base 108. The first clamping portion 110a and the second clamping portion 110b are adapted to clamp the frame 20. The spacing between the first clamping portion 110a and the second clamping portion 110b is less than the thickness of the frame 20, which helps the clip 100 to be firmly held on the frame 20. In the illustrated embodiment, the first clamping portion 110a can abut against the upper surface 21 of the frame 20 and the second clamping portion 110b can abut against the lower surface 22 of the frame 20.

[0072] In the illustrated embodiment, the card clip 100 includes a plurality of contact portions 104, and the plurality of contact portions 104 may include at least one first contact portion 104a and at least one second contact portion 104b. The first contact portion 104a protrudes from the first clamping portion 110a toward the interior of the card clip body 102. The second contact portion 104b protrudes from the second clamping portion 110b toward the interior of the card clip body 102. The first contact portion 104a and the second contact portion 104b are adapted to abut against the upper surface 21 and the lower surface 22 of the frame 20, respectively, to make electrical contact with the frame 20. In the illustrated embodiment, the card clip 100 includes two first contact portions 104a and two second contact portions 104b.

[0073] It is conceivable that, in some variations of embodiments, the clip may include other suitable numbers of contact portions; in some variations of embodiments, the contact portion of the clip may be disposed on only one of the first clamping portion and the second clamping portion.

[0074] In the illustrated embodiment, the first contact portion 104a and the second contact portion 104b are both in the form of barbs. The contact portion 104 in the form of barbs can penetrate the frame 20. This is particularly advantageous for an aluminum frame, and can pierce the metal oxide film on the surface of the aluminum frame to achieve good electrical contact between the barbs and the aluminum frame, thereby contributing to the grounding of the aluminum frame. In addition, the contact portion 104 in the form of barbs can also prevent the frame 20 from slipping out from the inside of the clip body 102, helping the clip 100 to remain firmly on the frame 20. It is conceivable that in other embodiments, the contact portion can be in the form of a convex portion, and the contact portion in the form of a convex portion can achieve good electrical contact with, for example, a steel frame.

[0075] Continue to refer to Figures 2A to 3C, the grounding connection portion 106 is in the form of a protruding piece. In the illustrated embodiment, the grounding connection portion 106 extends from the second clamping portion 110b toward the outside of the clamp body 102. The wire 200 includes a wire body 202 and an electrical terminal 204 disposed at the end of the wire body 202. Optionally, the electrical terminal 204 is fixed to the end of the wire body 202 by crimping, and defines a receiving channel 206 for receiving the grounding connection portion 106.

[0076] The grounding connection portion 106 is adapted to be snap-fitted with the electrical terminal 204 of the wire 200. The grounding connection portion 106 is adapted to be inserted into the receiving channel 206 of the electrical terminal 204 of the wire 200 and, for example, is interference-fitted with the receiving channel 206 to be mechanically and electrically connected to the electrical terminal 204 of the wire 200. In the illustrated embodiment, the electrical terminal 204 includes a substrate 201 and a first retaining wing 203 and a second retaining wing 205 extending from opposite sides of the substrate 201, respectively. The substrate 201, the first retaining wing 203 and the second retaining wing 205 jointly define the receiving channel 206. When the grounding connection portion 106 is inserted into the receiving channel 206, the first retaining wing 203 and the second retaining wing 205 press against the grounding connection portion 106 to retain the grounding connection portion 106 in the receiving channel 206. The free end of the grounding connection portion 106 may be provided with a chamfer 107 so that the grounding connection portion 106 is inserted into the receiving channel 206. The grounding connection part 106 includes a snap-fit ​​hole 112, and the electrical terminal 204 of the wire 200 includes a protrusion 208 protruding from the substrate 201 toward the inside of the receiving channel 206. The snap-fit ​​hole 112 is suitable for snapping with the protrusion 208 of the electrical terminal 204 to prevent the grounding connection part 106 from being disengaged from the receiving channel 206, while further increasing the electrical contact between the grounding connection part 106 and the electrical terminal 204. The first retaining wing 203 and the second retaining wing 205 can provide good electrical contact between the substrate 201 of the electrical terminal 204 and the grounding connection part 106, and also facilitate stable snap-fit ​​and good electrical contact between the snap-fit ​​hole 112 and the protrusion 208.

[0077] Return to reference Figure 2A , the electrical connection between the photovoltaic components 1 can be achieved through the clamp 100 and the wire 200. Figure 2A In the embodiment, the electrical connection between the two photovoltaic modules 1 is realized by two clips 100 and a wire 200, wherein each clip 100 is clamped on the frame 20 of a corresponding photovoltaic module 1, and the grounding connection parts 106 of the two clips 100 are connected to each other through the wire 200. In addition, the photovoltaic module 1 can also be connected to a grounding device through the clip 100 and the wire 200 to conduct static electricity on the frame 20 of the photovoltaic module 1.

[0078] FIG. 4A to FIG. 5A clip 100 for a photovoltaic assembly 1 according to a second embodiment of the utility model is shown, which is similar to the clip according to the first embodiment, and the difference between the two is mainly that the clip 100 according to the second embodiment further includes a cable holding portion 114 connected to the clip body 102. In the illustrated embodiment, the clip 100 includes two cable holding portions 114. The two cable holding portions 114 extend from the second clamping portion 110b of the clip body 102 toward the outside of the clip body 102. Each cable holding portion 114 is in an arc shape to receive and hold the cable 40. In the illustrated embodiment, the cable holding portion 114 and the grounding connection portion 106 are arranged on the same side of the clip, more specifically, both are arranged at the second clamping portion 110b of the clip body 102. It is conceivable that in other embodiments, the cable holding portion and the grounding connection portion can also be respectively arranged on opposite sides of the clip, for example, respectively arranged at the first clamping portion and the second clamping portion of the clip body. It is contemplated that in other embodiments, the clip may include other suitable numbers of cable retaining portions, such as one, three or more cable retaining portions.

[0079] Figure 6 to Figure 7 A clip 100 for a photovoltaic assembly 1 according to a third embodiment of the utility model is shown, which is similar to the clip according to the second embodiment. The difference between the two mainly lies in that the clip 100 according to the third embodiment includes a cable holding portion 114 for holding a cable 40 and does not have a grounding connection portion for connecting to a wire.

[0080] Figures 8 to 11B A clamp 100 for a photovoltaic component 1 according to a fourth embodiment of the utility model is shown, which is similar to the clamp according to the first embodiment. The main difference between the two is that the clamp 100 according to the fourth embodiment also includes a guide wing 116 connected to the clamp body 102, and the guide wing 116 is suitable for being arranged at the frame 20 of the photovoltaic component 1 and is configured to form a gap with the photovoltaic component 1 to attract the accumulated water on the photovoltaic component 1 and guide the accumulated water to be discharged.

[0081] Reference Figures 8 to 11B In the illustrated embodiment, the clip 100 according to the fourth embodiment can be integrally formed of metal by stamping. The guide wings 116 and the ground connection portion 106 of the clip 100 are connected to the first clamping portion 110a and the second clamping portion 110b, respectively. The first clamping portion 110a and the second clamping portion 110b of the clip body 102 are both provided with windows 111 to reduce their rigidity, thereby reducing the force required to clamp the clip 100 on the frame 20.

[0082] In the illustrated embodiment, the clip 100 includes two guide wings 116, which are respectively disposed at opposite sides of the first clamping portion 110a. It is conceivable that in other embodiments, the clip may also include other suitable numbers of guide wings, such as one, three or more guide wings.

[0083] The guide wing 116 includes a guide groove 118 on the side facing the frame 20 to form the aforementioned gap with the photovoltaic assembly 1. The guide wing 116 may include a first wing section 120 and a second wing section 122 connected to each other. The guide groove 118 extends on the first wing section 120 and the second wing section 122. In the illustrated embodiment, the guide groove 118 extends along the entire first wing section 120 and the second wing section 122.

[0084] The first wing section 120 extends toward the photovoltaic panel 30 of the photovoltaic assembly 1. The first wing section 120 can use the capillary effect to attract the accumulated water on the photovoltaic assembly 1 (especially the accumulated water at the junction of the photovoltaic panel and the frame) by means of the guide groove 118, and use the siphon effect to guide the accumulated water to flow toward the second wing section 122. The second wing section 122 extends along the frame 20 of the photovoltaic assembly 1. The second wing section 122 can use the siphon effect to guide the accumulated water attracted by the first wing section 120 to be discharged by means of the guide groove 118.

[0085] In the illustrated embodiment, the first wing section 120 is in a straight line shape and extends generally along the upper surface 21 of the frame 20 to above the photovoltaic panel 30. The second wing section 122 is in an L shape and includes a first portion 124 and a second portion 126 that are generally perpendicular to each other. The first portion 124 is adjacent to the first wing section 120 and extends generally along the upper surface 21 of the frame 20. The second portion 126 extends generally along the side surface 23 of the frame 20. The first portion 124 of the second wing section 122 forms an obtuse angle α with the first wing section 120, so that while the first wing section 120 extends toward the photovoltaic panel 30 of the photovoltaic assembly 1, the second wing section 122 extends generally along the frame 20 of the photovoltaic assembly 1.

[0086] It is conceivable that, in other embodiments, the second wing segment may also be in a straight line shape. In other words, the second wing segment may not have the aforementioned second portion, but may only extend approximately along the upper surface of the frame. In yet other embodiments, the second wing segment may also be in a U-shape. In other words, in addition to the aforementioned first and second portions, the second wing segment may also include a third portion extending from the second portion approximately along the lower surface of the frame, which allows the guide wing to be self-clamped on the frame and thus firmly retained on the frame.

[0087] In the illustrated embodiment, the guide wing 116 also includes a through hole 128 in fluid communication with the guide groove 118. The through hole 128 can facilitate the discharge of impurities such as dust and silt entrained in the accumulated water, and prevent the impurities from clogging the guide groove 118. At the same time, the through hole 128 is also conducive to the air pressure in the guide groove 118 being consistent with the outside, so that the accumulated water can be smoothly discharged along the guide groove 118. In the illustrated embodiment, each guide wing 116 includes two through holes 128 in fluid communication with the guide groove 118. It can be understood that in other embodiments, each guide wing 116 can also include other suitable numbers of through holes.

[0088] In the illustrated embodiment, the clip 100 further includes a transition portion 130, and the guide wings 116 are connected to the clip body 102 through at least the transition portion 130. The transition portion 130 is raised relative to the guide wings 116 in a direction away from the frame 20. The raised transition portion 130 can prevent the accumulated water attracted by the guide wings 116 and the impurities carried by the guide wings 116 from flowing to the clip body 102 (for example, flowing to the contact portion 104) to affect the electrical contact between the clip body 102 and the frame 20. In the illustrated embodiment, the transition portion 130 is in the shape of an arch. It is conceivable that in other embodiments, the transition portion can also have other suitable shapes, such as a wave shape.

[0089] In the illustrated embodiment, the grounding connection portion 106 of the clip 100 extends from the clip body 102 toward the outside of the clip body 102. The grounding connection portion 106 is adapted to be inserted into the receiving channel 206 of the electrical terminal 204 of the wire 200 and, for example, is interference-fitted with the receiving channel 206 to be mechanically and electrically connected to the electrical terminal 204 of the wire 200. The grounding connection portion 106 includes a snap-fitting hole 112, and the electrical terminal 204 of the wire 200 includes a protrusion 208 protruding toward the inside of the receiving channel 206. The snap-fitting hole 112 is adapted to be snapped with the protrusion 208 of the electrical terminal 204 to prevent the grounding connection portion 106 from being disengaged from the receiving channel 206, while further increasing the electrical contact between the grounding connection portion 106 and the electrical terminal 204.

[0090] Figures 12 to 15 A fifth embodiment of the present invention is shown as a clamp 100 for a photovoltaic assembly 1 , which is similar to the clamp according to the fourth embodiment. The main difference between the two is that the clamp body 102 and the guide wings 116 of the clamp 100 according to the fifth embodiment are formed separately.
