Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic frame connector and a connection method thereof. Background Art

[0002] In the rapid development of the photovoltaic industry, photovoltaic connectors are key components to ensure the structural stability of photovoltaic modules. Their performance directly affects the operating efficiency and service life of the entire photovoltaic system.

[0003] The photovoltaic frames on the current market are usually connected with glue-type connectors or sleeve-type connectors. Glue-type connectors require construction workers to have a high level of glue injection and experience. If the amount of glue injection is uneven, it will affect the strength and sealing of the connection, and the glue injection process takes a certain amount of time, which is not conducive to large-scale application; sleeve-type connectors mainly rely on the friction between the sleeve and the profile and the bonding force of a small amount of glue to achieve connection. They have high requirements for profile accuracy. If the dimensional accuracy of the profile is not enough, the connector will not fit tightly with the profile, and may become loose, affecting the reliability of the connection. In contrast, the cost of mortise and tenon connectors is more economical. However, during the use of existing mortise and tenon connectors, the risk of deformation of the non-felt (full yarn) corner code composite profile will increase, resulting in cracking of the photovoltaic profile.

[0004] To this end, a photovoltaic frame connector and a connection method thereof are proposed to meet the photovoltaic industry's demand for efficient installation, high stability and high safety of the connector. Summary of the invention

[0005] The purpose of the present invention is to provide a photovoltaic frame connector and a connection method thereof in view of the existing problems, so as to solve the technical problems raised in the background technology.

[0006] The present invention is realized by the following technical solutions: a photovoltaic frame connector, comprising a main body, a connecting strip and an embedded part; The main body comprises two sleeves, and the two sleeves are vertically distributed, and a receiving cavity is provided on the sleeve, and an inner groove is provided on the inner wall of the receiving cavity; The embedded part includes an embedded component, which is located inside the accommodating cavity. The embedded component is connected to the inner wall of the accommodating cavity through a connecting strip. The embedded component, the connecting strip and the accommodating cavity form an integrated structure.

[0007] As a preferred solution of the photovoltaic frame connector of the present invention, the embedded component is provided with an end protrusion, and the end protrusion is used to engage with the inner groove.

[0008] As a preferred solution of the photovoltaic frame connector of the present invention, the outer wall of the embedded component is fixedly connected with a clamping block for clamping with the inner wall groove of the photovoltaic frame profile.

[0009] As a preferred solution of the photovoltaic frame connector of the present invention, a chamfered surface is provided on the clamping block.

[0010] As a preferred solution of the photovoltaic frame connector of the present invention, the main body is used to connect with a straight-cut photovoltaic frame profile or a bevel-cut photovoltaic frame profile. The main body used for the straight-cut photovoltaic frame profile consists of a connecting block and two sleeves. The connecting block is a right-angle turning structure, and the connecting block is located between the two sleeves. The two sleeves are connected by the connecting block.

[0011] As a preferred solution of the photovoltaic frame connector of the present invention, a guide groove is provided on the connecting block.

[0012] As a preferred solution of the photovoltaic frame connector of the present invention, a tail protrusion is also provided on the embedded component.

[0013] As a preferred solution of the photovoltaic frame connector of the present invention, a notch is provided on the sleeve, and the outer wall of the tail protrusion is used for clamping with the inner wall of the notch.

[0014] As a preferred solution of the photovoltaic frame connector of the present invention, a limit block for abutting against the end of the photovoltaic frame profile is provided on the embedded component.

[0015] A method for connecting a photovoltaic frame connector comprises the following steps: S1. Place the connector between two photovoltaic frame profiles to be connected; S2, performing a pushing operation to make the limit block on the connector collide with the side wall of the photovoltaic frame profile; S3, the connecting strip breaks, so that the inner insert and the sleeve are connected into one; S4. The card block on the connector is inserted into the card slot inside the photovoltaic frame profile, so that the connector and the photovoltaic frame profile are connected as one.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention provides a photovoltaic frame connector and a connection method thereof. The connector adopts a mortise and tenon structure design, and is installed by a push-type operation between the main body and the embedded part. The operation is simple. After the installation is completed, the main body of the connector is connected to the photovoltaic frame profile as a whole, and the overall strength is high, which effectively prevents the connector from deforming when subjected to force. By utilizing the plasticity of the connector, when the felt-free composite profile photovoltaic frame is quickly connected together, not only the overall strength of the felt-free composite profile photovoltaic frame can be improved, but also the problem of cracking of the felt-free composite profile photovoltaic frame can be effectively prevented, so that the connector can be applicable to a variety of composite profiles such as those with felt and without felt, and can simultaneously meet the use requirements of efficient installation, high stability and high safety.

[0017] 2. The present invention provides a photovoltaic frame connector and a connection method thereof. In the connector, an oblique surface is provided on the card block of the inner sleeve, and the closer to the opening of the sleeve, the thinner the surface is, which plays a guiding role, so that the card block can be more smoothly pushed into the card slot of the photovoltaic frame profile. By adopting a card connection method, the connector can be tightly connected to the photovoltaic frame profile without gluing, with low process complexity and high overall strength.

[0018] 3. The present invention provides a photovoltaic frame connector and a connection method thereof. A guide groove is provided on the connecting block in the connector. The guide groove can be used to drain rainwater on the photovoltaic panel to prevent water accumulation on the surface of the panel, thereby avoiding problems such as reduced photovoltaic panel power generation efficiency and corrosion of the cell due to water accumulation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The connector is used for connecting photovoltaic frame profiles. Existing photovoltaic frame profiles generally include two types: straight-cut photovoltaic frame profiles and bevel-cut photovoltaic frame profiles.

[0023] Embodiment 1: See also Figure 1-4 As shown, the present invention provides a technical solution: a photovoltaic frame connector, including a main body 100, a connecting strip 110 and an embedded part 120; The main body 100 includes two sleeves 1001, and the two sleeves 1001 are vertically distributed. The sleeves 1001 are provided with a receiving cavity 1002, and the inner wall of the receiving cavity 1002 is provided with an inner groove 1003; The embedded part 120 includes an embedded component 1201, which is located inside the accommodating cavity 1002. The embedded component 1201 is connected to the inner wall of the accommodating cavity 1002 through the connecting strip 110. The embedded component 1201, the connecting strip 110 and the accommodating cavity 1002 are an integrated structure; the connecting strip 110 can break when subjected to force, so that the embedded component 1201 is stuck in the sleeve 1001, thereby enhancing the plasticity and overall strength of the connecting component.

[0024] The inner insert 1201 is provided with an end protrusion 1203, which is used to engage with the inner groove 1003. The inner insert 1201 is also provided with a tail protrusion 1204. The sleeve 1001 is provided with a notch 1004, and the outer wall of the tail protrusion 1204 is used to engage with the inner wall of the notch 1004. The outer wall of the embedded part 1201 is fixedly connected with a block 130 for engaging with the slot on the inner wall of the photovoltaic frame profile, and a chamfered surface 1301 is provided on the block 130; it should be noted that the closer the chamfered surface 1301 is to the port of the tail protrusion 1204, the thinner the section is, which serves as a guide and facilitates the smooth insertion of the block 130 into the slot of the photovoltaic frame profile; in addition, the position of the slot on the inner wall of the photovoltaic frame profile remains corresponding to the position of the block 130 when the sleeve 1001 is fully inserted into the photovoltaic frame profile.

[0025] The embedded part 1201 is provided with a limit block 1202 for abutting against the end of the photovoltaic frame profile; correspondingly, the end of the photovoltaic frame profile is provided with a limit groove for matching with the limit block 1202 to ensure a stable connection between the connector and the photovoltaic frame profile.

[0026] The connecting piece in this embodiment is suitable for beveled photovoltaic frame profiles. When in use, the sleeve 1001 is aligned with the cavity of the beveled photovoltaic frame profile and inserted. During this process, the connecting strip 110 is broken by force, so that the embedded part 1201 is inserted into the accommodating cavity 1002 of the sleeve 1001, and the notch of the photovoltaic frame profile is tightly pressed against the limit block 1202 on the main body 100, and the block 130 on the main body 100 is inserted into the slot of the photovoltaic frame profile, thereby connecting the two photovoltaic frame profiles together through the connecting piece.

[0027] In summary, the connector adopts a mortise and tenon structure design, and the main body 100 and the embedded part 120 are installed by a push-type operation, which is easy to operate. After the installation is completed, the connector main body 100 is connected to the photovoltaic frame profile as a whole, and the main body 100 is clamped inside the cavity of the photovoltaic frame profile. Under the action of the clamping block 130, it is in an immobile state, thereby enhancing the strength and load-bearing capacity of the end of the photovoltaic frame profile, and effectively preventing the connector from deforming when subjected to force. The plasticity of the connector can be used to quickly connect the photovoltaic frame of the non-felt (full yarn) composite profile, and at the same time, it not only improves the overall strength of the photovoltaic frame of the non-felt (full yarn) composite profile, but also effectively prevents the problem of cracking of the photovoltaic frame of the non-felt (full yarn) composite profile, so that the connector can be suitable for a variety of composite profiles such as felt and non-felt (full yarn).

The outer wall of the embedded part 1201 is fixedly connected with a block 130 for engaging with the slot on the inner wall of the photovoltaic frame profile, and a chamfered surface 1301 is provided on the block 130; it should be noted that the closer the chamfered surface 1301 is to the port of the tail protrusion 1204, the thinner the section is, which serves as a guide, making it convenient to smoothly insert the block 130 into the slot of the photovoltaic frame profile 2 when in use; in addition, the position of the slot on the inner wall of the photovoltaic frame profile remains corresponding to the position of the block 130 when the sleeve 1001 is fully inserted into the photovoltaic frame profile.

When the straight-cut photovoltaic frame profiles are connected together through a connecting piece, the connecting block is located at the corners of the two photovoltaic frame profiles to protect the connecting piece. The main body 100 of the connecting piece consists of two sleeves 1001 and a connecting block connecting them together. A guide groove is provided on the upper surface of the connecting block. The rainwater on the photovoltaic panel can be discharged in time through the guide groove on rainy days to prevent water accumulation on the surface of the panel.

[0032] The connector in this embodiment is suitable for applications in straight-cut photovoltaic frame profiles. When in use, the sleeve 1001 is aligned with the cavity of the bevel-cut photovoltaic frame profile and inserted, and the connecting strip 110 is broken under force, so that the embedded part 1201 is inserted into the accommodating cavity 1002 of the sleeve 1001, and the notch of the photovoltaic frame profile is tightly pressed against the limit block 1202 on the main body 100, and the block 130 on the main body 100 is inserted into the slot of the photovoltaic frame profile, so that the two photovoltaic frame profiles are connected together through the connector, thereby enhancing the plasticity and overall strength of the connector.

[0033] In summary, the connector adopts a mortise and tenon structure design, and the main body 100 and the embedded part 120 are installed by a push-type operation, which is easy to operate. After the installation is completed, the connector main body 100 is connected to the photovoltaic frame profile as a whole, and the main body 100 is clamped inside the cavity of the photovoltaic frame profile. Under the action of the clamping block 130, it is in an immobile state, thereby enhancing the strength and load-bearing capacity of the end of the photovoltaic frame profile, and effectively preventing the connector from deforming when subjected to force. The plasticity of the connector can be used to quickly connect the photovoltaic frame of the non-felt (full yarn) composite profile, and at the same time, it not only improves the overall strength of the photovoltaic frame of the non-felt (full yarn) composite profile, but also effectively prevents the problem of cracking of the photovoltaic frame of the non-felt (full yarn) composite profile, so that the connector can be suitable for a variety of composite profiles such as felt and non-felt (full yarn).
