Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and more specifically, to a wiring component and a photovoltaic device. Background Technology

[0002] In photovoltaic equipment, when the cables of the solar panels are in use, they may be bent or bent near the junction box and output connector. This can cause the cables to be affected by the junction box and output connector, making them prone to leakage and other problems.

[0003] Therefore, designing a wiring assembly that can improve the service life of cables has become an urgent problem to be solved. Utility Model Content

[0004] The present invention aims to at least solve the problem that in photovoltaic equipment of the prior art or related technologies, the wires are prone to bending and other operations near the connection points with the junction box and the output terminal, which leads to easy damage to the cables.

[0005] Therefore, this utility model provides a wiring assembly.

[0006] The second aspect of this utility model provides a photovoltaic device.

[0007] To achieve the above objectives, this utility model provides a wiring assembly for photovoltaic equipment. The wiring assembly includes: a junction box; a cable including a body, a connector, and an adapter, wherein the connector and the adapter are respectively connected to the two ends of the body, and the first end of the connector is connected to the junction box; an output connector connected to the second end of the adapter; a first buffer member disposed at the connection between the body and the connector; and / or a second buffer member disposed at the connection between the body and the adapter.

[0008] This utility model provides a wiring assembly for photovoltaic equipment. The photovoltaic panel in the photovoltaic equipment transmits electrical energy to the power-consuming equipment via the wiring assembly. Specifically, the electrical energy from the photovoltaic panel sequentially passes through a junction box, a cable, and an output connector before flowing to the power-consuming equipment. A connector is located at one end of the main body, and a first buffer is located between the connector and the main body. When the connector is installed in the junction box, the first buffer protects the cable, preventing damage caused by direct contact with the junction box during bending or pulling. Similarly, an adapter is located at the other end of the cable body, and a second buffer is located between the adapter and the main body. When the adapter is connected to the output connector, the second buffer protects the cable, preventing damage caused by direct contact with the output connector during bending or pulling. In this application, by setting the first and / or second buffers, the cable maintains good flexibility, avoiding damage to the conductors during frequent bending and other operations, thereby extending the product's service life.

[0009] In addition, the wiring assembly provided in this application may also have the following additional technical features:

[0010] In some embodiments, the cross-section of the body may be flat.

[0011] In this embodiment, the cable body is designed to be flat, perpendicular to the cable's extension direction, with a width greater than its thickness. Compared to round cables, this design allows the cable to pass directly through narrow spaces such as doors and windows when the photovoltaic equipment wiring needs to pass through them, without affecting the normal closing and use of doors and windows. Simultaneously, the flat cable has a larger contact area with the mounting carrier, enabling more stable installation on the carrier, requiring less height, and offering better bending performance.

[0012] In some embodiments, the body may optionally include: a first wire harness; a second wire harness disposed side by side with the first wire harness; an insulating sleeve disposed outside the first wire harness and the second wire harness, and separating the first wire harness and the second wire harness; and a connector including a first connector and a second connector, wherein the first connector is connected to one end of the first wire harness and the second connector is connected to one end of the second wire harness.

[0013] In this embodiment, the main body includes a first wire harness and a second wire harness, and the junction box completes the positive and negative connection through the first and second wire harnesses. Specifically, the first and second wire harnesses are arranged side by side, corresponding to the positive and negative connections of the junction box, respectively. Meanwhile, an insulating sleeve is provided on the outside of the first and second wire harnesses, which can separate the first and second wire harnesses, thereby protecting the wire harnesses, preventing mutual interference between the two wire harnesses, and preventing the first and second wire harnesses from being affected by external interference. This design also helps to improve the structural compactness of the wiring assembly, providing convenient conditions for miniaturization and lightweight design of the wiring assembly.

[0014] In some embodiments, the adapter may optionally include a first adapter and a second adapter, the first adapter being connected to the other end of the first wiring harness and the second adapter being connected to the other end of the second wiring harness.

[0015] In some embodiments, the insulating sleeve may optionally include: a first insulating sleeve fitted onto a first wire harness; and a second insulating sleeve fitted onto a second wire harness, wherein the first insulating sleeve and the second insulating sleeve are an integral structure.

[0016] In this embodiment, by providing an insulating sleeve on the outer surface of each wire harness and forming two insulating sleeves into an integral structure, the first and second insulating sleeves achieve mutual isolation between the two wire harnesses. Simultaneously, the overall stability and sealing of the insulating sleeves are ensured, further improving the insulation effect of the cable and enhancing the safety of photovoltaic equipment.

[0017] In some embodiments, the cable may optionally include a groove disposed on the outer surface of the insulating sleeve and located between the first wire harness and the second wire harness.

[0018] In this embodiment, by setting the groove on the outer surface of the insulating sleeve and located between the first and second wire harnesses, when it is necessary to separate the double-stranded wire harness into two single-stranded wire harnesses, the insulating sleeve can be torn open directly along the groove position to separate the first and second wire harnesses into two single-stranded wire harnesses, thereby increasing the flexibility of cable use to meet the wiring needs of different photovoltaic equipment.

[0019] In some embodiments, the groove may be a V-groove, and there may be multiple V-grooves disposed on opposite sides of the insulating sleeve.

[0020] In this embodiment, V-grooves are provided on opposite sides of the insulating sleeve, specifically on the upper and lower surfaces along the cable thickness direction. This further facilitates the separation of the two-strand wire harness. Simultaneously, it enhances the cable's flexibility to a certain extent, making it easier to bend and adapt to complex wiring environments. Furthermore, the V-groove structure helps distribute stress, reducing cable damage during bending.

[0021] In some embodiments, the junction box may optionally include: an upper cover; a lower cover, which together with the upper cover forms a receiving space; a conductive copper sheet disposed in the receiving space; and a mounting hole disposed in the lower cover, through which a cable connector passes and connects to the conductive copper sheet.

[0022] In this embodiment, the junction box's upper and lower covers form a containment space, protecting internal components such as conductive copper sheets and diodes from external environmental corrosion. The conductive copper sheets, positioned within this space, are used to connect cables and facilitate current transmission. Mounting holes allow cables to pass through and connect to the conductive copper sheets, resulting in a more compact junction box and cable connection structure and ensuring the stability of the photovoltaic equipment connection.

[0023] In some embodiments, optionally, the conductive copper sheet includes: a first conductive copper sheet connected to the first wire harness via a first connector; a second conductive copper sheet connected to the second wire harness via a second connector; the junction box further includes: a diode disposed in the receiving space, located between the first conductive copper sheet and the second conductive copper sheet; wherein the anode of the diode is connected to the first conductive copper sheet, and the cathode of the diode is connected to the second conductive copper sheet.

[0024] In this embodiment, the first and second conductive copper sheets are connected to the first and second wiring harnesses, respectively. The positive terminal of the solar panel in the photovoltaic device is connected to the first conductive copper sheet, and the negative terminal is connected to the second conductive copper sheet, thereby ensuring effective current transmission. Furthermore, placing a diode between the first and second conductive copper sheets, with its anode connected to the first conductive copper sheet and its cathode connected to the second conductive copper sheet, provides unidirectional conductivity and prevents current backflow. Specifically, when lighting conditions change or other factors affect the system, current backflow may occur. For example, at night or when there is insufficient sunlight, the photovoltaic panel no longer generates electricity and may instead become a "load." Without the diode, current from other parts of the system might flow back to the photovoltaic panel, causing it to overheat or even be damaged. The diode has unidirectional conductivity; its resistance is very low when forward-biased, allowing current to flow smoothly. When reverse-biased, current can hardly flow. By placing the diode between the two welded conductive copper sheets, current backflow can be effectively prevented, ensuring that current flows only in the prescribed direction, protecting the circuit components in the photovoltaic device, and improving stability and reliability.

[0025] In some embodiments, the wiring assembly may optionally include: a fixing member, sleeved on the cable, fixedly connected to the cable, and located in the receiving space; and a limiting member, disposed in the receiving space and located between the fixing member and the mounting hole, for limiting the movement of the cable in the receiving space.

[0026] In this embodiment, the fastener is sleeved on and fixedly connected to the cable. When the cable is connected to the junction box, the fastener is located within the receiving space. The fastener is an SR (Strain Relief) fastener to enhance the stability of the connection between the cable and the junction box and prevent the cable from loosening. A limiting member is located between the fastener and the mounting hole to limit the movement of the cable within the receiving space. This means that when the cable is pulled externally, the cable in the junction box will not be subjected to tensile force, ensuring the cable's fixation within the junction box and preventing poor contact or breakage between the cable and the conductive copper sheet due to pulling, thereby improving the stability of the wiring assembly.

[0027] In some embodiments, the first wire harness may be a braided copper strip; and / or the second wire harness may be a braided copper strip.

[0028] In this embodiment, the first and / or second wire harnesses are made of braided copper tape, which improves the conductivity of the cable and ensures the current transmission efficiency of the photovoltaic equipment. The braided copper tape is formed by intertwining multiple fine copper wires into a flat shape and then pressing it with a roller press. This ensures the stability of the intertwining of the copper wires and also gives the braided copper tape excellent flexibility, helping the cable adapt to different installation environments and making it less prone to breakage when subjected to external forces, thus improving the cable's durability.

[0029] In some embodiments, the output connector may optionally include: a male plug, one end of which is connected to the second end of the adapter; and a female plug, which is inserted into the other end of the male plug.

[0030] In this embodiment, the male plug and female plug form an output connector, which facilitates connection with other devices, enabling quick and convenient connection between photovoltaic equipment and external electrical equipment, and improving the convenience and versatility of equipment use.

[0031] In some embodiments, the output connector may optionally include: a protective sleeve, which is fitted over the outside of the male plug and located at the connection between the male plug and the adapter; and an anti-loss rope, one end of which is connected to the male plug and the other end of which is connected to the female plug.

[0032] In this embodiment, a protective sleeve is fitted over the male plug and located at the connection point between the male plug and the adapter, thereby protecting the male plug and the connection point from damage caused by external interference. The protective sleeve can be an insulating sleeve, enhancing the insulation performance of the output connector and preventing electric shock. The anti-loss rope is connected to the male plug and female plug at both ends, preventing the female plug from being lost when it is not plugged into the male plug.

[0033] In some embodiments, the male plug is optionally an Anderson male plug, the female plug is optionally an Anderson female plug, and the protective sleeve is the outer sheath of the Anderson male plug.

[0034] The second aspect of this application provides a photovoltaic device, comprising: a wiring assembly as described in any of the technical solutions of the first aspect.

[0035] The photovoltaic equipment provided in this application includes the wiring components of any of the technical solutions in the first aspect. Since the photovoltaic equipment provided in this application includes the wiring components of any of the technical solutions in the first aspect, it also possesses all the beneficial effects of the wiring components in any of the technical solutions in the first aspect, which will not be elaborated further here.

[0045] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0047] The following reference Figures 1 to 5 This application describes a wiring assembly 1 and a photovoltaic device 2 according to some embodiments.

[0048] According to an embodiment of the first aspect of the present invention, such as Figure 1As shown, this utility model provides a wiring assembly 1 for a photovoltaic device 2. The wiring assembly 1 includes: a junction box 10; a cable 11 including a body 111, a connector 113, and an adapter 114, wherein the connector 113 and the adapter 114 are respectively connected to the two ends of the body 111, and the first end of the connector 113 is connected to the junction box 10; an output connector 12 connected to the second end of the adapter 114; a first buffer 13 disposed at the connection between the body 111 and the connector 113; and / or a second buffer 14 disposed at the connection between the body 111 and the adapter 114.

[0049] According to this utility model, a wiring assembly 1 for a photovoltaic device 2 is provided. The photovoltaic panel in the photovoltaic device 2 transmits electrical energy to the electrical device via the wiring assembly 1 to supply power. Specifically, the electrical energy of the photovoltaic panel passes sequentially through a junction box 10, a cable 11, and an output connector 12, and then flows to the electrical device to supply power. A connector 113 is disposed at one end of the body 111, and a first buffer 13 is disposed between the connector 113 and the body 111. Thus, when the connector 113 is installed in the junction box 10, the first buffer 13 can be used to protect the cable 11, preventing the cable 11 from directly contacting the junction box 10 and causing damage when the cable 11 is bent or pulled. Similarly, the adapter 114 is located at the other end of the cable 11 body 111, and the second buffer 14 is located between the adapter 114 and the body 111. Thus, when the adapter 114 is connected to the output connector 12, the second buffer 14 can protect the cable 11, preventing damage caused by direct contact between the cable 11 and the output connector 12 during bending or pulling. In this application, by providing the first buffer 13 and / or the second buffer 14, the cable 11 can maintain good flexibility, avoiding damage to the conductors during frequent bending and other operations, thereby extending the product's service life.

[0050] In some embodiments, optionally, such as Figure 3 As shown, the cross-section of the body 111 is flat.

[0051] In this embodiment, the body 111 of the cable 11 is made flat, that is, perpendicular to the extension direction of the cable 11, and the width of the body 111 is greater than its thickness. Compared with the round cable 11, this design allows the cable 11 to pass directly through narrow spaces such as doors and windows when the photovoltaic device 2 needs to be routed, without affecting the normal closing and use of the doors and windows. At the same time, the flat cable 11 has a larger contact area with the mounting carrier, which allows it to be installed more stably on the carrier, with a smaller height, and the cable 11 has better bending performance.

[0052] In some embodiments, optionally, such as Figure 2 and Figure 3As shown, the body 111 includes: a first wire harness 1112; a second wire harness 1114, arranged side by side with the first wire harness 1112; an insulating sleeve 112, sleeved on the outside of the first wire harness 1112 and the second wire harness 1114, and separating the first wire harness 1112 and the second wire harness 1114; and a connector 113 including a first connector 113 and a second connector 113, wherein the first connector 113 is connected to one end of the first wire harness 1112, and the second connector 113 is connected to one end of the second wire harness 1114.

[0053] In this embodiment, the body 111 includes a first wire harness 1112 and a second wire harness 1114. The junction box 10 completes the positive and negative connection through the first wire harness 1112 and the second wire harness 1114. Specifically, the first wire harness 1112 and the second wire harness 1114 are arranged side by side, and the first wire harness 1112 and the second wire harness 1114 correspond to the positive and negative connection of the junction box 10, respectively. At the same time, an insulating sleeve 112 is provided on the outside of the first wire harness 1112 and the second wire harness 1114, and the insulating sleeve 112 can separate the first wire harness 1112 and the second wire harness 1114, thereby protecting the wire harnesses, preventing mutual interference between the two wire harnesses, and preventing the first wire harness 1112 and the second wire harness 1114 from external interference. At the same time, this design helps to improve the structural compactness of the wiring assembly 1, and provides convenient conditions for the miniaturization and lightweight design of the wiring assembly 1.

[0054] In some embodiments, the adapter 114 may optionally include a first adapter and a second adapter, the first adapter being connected to the other end of the first wiring harness 1112 and the second adapter being connected to the other end of the second wiring harness 1114.

[0055] In some embodiments, optionally, such as Figure 3 As shown, the insulating sleeve 112 includes: a first insulating sleeve 1122, which is sleeved on the first wire harness 1112; and a second insulating sleeve 1124, which is sleeved on the second wire harness 1114. The first insulating sleeve 1122 and the second insulating sleeve 1124 are an integral structure.

[0056] In this embodiment, by providing an insulating sleeve 112 on the outer surface of each wire harness and forming two insulating sleeves 112 into an integral structure, the first insulating sleeve 1122 and the second insulating sleeve 1124 are used to achieve mutual isolation between the two wire harnesses. At the same time, the overall stability and sealing of the insulating sleeve 112 are also ensured, further improving the insulation effect of the cable 11 and enhancing the safety of the photovoltaic equipment 2.

[0057] In some embodiments, optionally, such as Figure 3 As shown, the cable 11 also includes a groove 115, which is provided on the outer surface of the insulating sleeve 112 and located between the first wire harness 1112 and the second wire harness 1114.

[0058] In this embodiment, by setting the groove 115 on the outer surface of the insulating sleeve 112 and between the first wire harness 1112 and the second wire harness 1114, when it is necessary to separate the double-strand wire harness into two single-strand wire harnesses, the insulating sleeve 112 can be torn open directly along the groove 115 to separate the first wire harness 1112 and the second wire harness 1114 into two single-strand wire harnesses, thereby increasing the flexibility of the cable 11 to meet the wiring needs of different photovoltaic devices 2.

[0059] In some embodiments, the groove 115 may be a V-groove, and there may be multiple V-grooves, which are disposed on opposite sides of the insulating sleeve 112.

[0060] In this embodiment, V-grooves are provided on opposite sides of the insulating sleeve 112, specifically on the upper and lower surfaces of the insulating sleeve 112 along the thickness direction of the cable 11. This further facilitates the separation operation between the two-strand wire harnesses. Simultaneously, it enhances the flexibility of the cable 11 to a certain extent, making it smoother when bent to adapt to complex wiring environments. Furthermore, the V-groove structure helps to disperse stress and reduce damage to the cable 11 during bending.

[0061] In some embodiments, optionally, such as Figure 1 and Figure 4 As shown, the junction box 10 includes: an upper cover 101; a lower cover 106, which together with the upper cover 101 form a receiving space 104; a conductive copper sheet 102 disposed in the receiving space 104; and a mounting hole 103 disposed in the lower cover 106, through which the connector 113 of the cable 11 passes and connects to the conductive copper sheet 102.

[0062] In this embodiment, the upper cover 101 and lower cover 106 of the junction box 10 form a receiving space 104, providing protection for internal components such as the conductive copper sheet 102 and diode 105, preventing them from being corroded by the external environment. The conductive copper sheet 102 is disposed in the receiving space 104 and is used to connect the cable 11 to realize current transmission. The mounting hole 103 facilitates the cable 11 to pass through and connect to the conductive copper sheet 102, making the connection structure between the junction box 10 and the cable 11 more compact and ensuring the connection stability of the photovoltaic device 2.

[0063] In some embodiments, optionally, such as Figure 1As shown, the conductive copper sheet 102 includes: a first conductive copper sheet 1022, which is connected to the first wire harness 1112 via a first connector 113; and a second conductive copper sheet 1024, which is connected to the second wire harness 1114 via a second connector 113. The junction box 10 also includes: a diode 105, which is disposed in the receiving space 104 and located between the first conductive copper sheet 1022 and the second conductive copper sheet 1024; wherein, the anode of the diode 105 is connected to the first conductive copper sheet 1022, and the cathode of the diode 105 is connected to the second conductive copper sheet 1024.

[0064] In this embodiment, the first conductive copper sheet 1022 and the second conductive copper sheet 1024 are connected to the first wiring harness 1112 and the second wiring harness 1114, respectively. The positive terminal of the solar panel in the photovoltaic device 2 is connected to the first conductive copper sheet 1022, and the negative terminal is connected to the second conductive copper sheet 1024, thus ensuring effective current transmission. Furthermore, a diode 105 is placed between the first conductive copper sheet 1022 and the second conductive copper sheet 1024, with its anode connected to the first conductive copper sheet 1022 and its cathode connected to the second conductive copper sheet 1024. This provides unidirectional conductivity and prevents current backflow. Specifically, when lighting conditions change or other factors affect the system, current backflow may occur. For example, at night or when there is insufficient sunlight, the photovoltaic panel no longer generates electricity and may instead become a "load." Without the diode 105, current from other parts may flow back to the photovoltaic panel, causing it to overheat or even be damaged. The diode 105 has unidirectional conductivity; its resistance is very small when forward-biased, allowing current to flow smoothly. When reverse-biased, almost no current can flow. By placing the diode 105 between two welded conductive copper sheets 102, reverse current flow can be effectively prevented, ensuring that the current can only flow in the specified direction, protecting the circuit components in the photovoltaic device 2, and improving stability and reliability.

[0065] In some embodiments, optionally, such as Figure 1 As shown, the wiring assembly 1 also includes: a fixing member 15, which is sleeved on the cable 11, fixedly connected to the cable 11, and located in the receiving space 104; and a limiting member 16, which is disposed in the receiving space 104 and located between the fixing member 15 and the mounting hole 103, for limiting the movement of the cable 11 in the receiving space 104.

[0066] In this embodiment, the fixing member 15 is sleeved on the cable 11 and fixedly connected to the cable 11. When the cable 11 is connected to the junction box 10, the fixing member 15 is located in the receiving space 104. The fixing member 15 is an SR (Strain Relief) fixing member to enhance the stability of the connection between the cable 11 and the junction box 10 and prevent the cable 11 from loosening. The limiting member 16 is located between the fixing member 15 and the mounting hole 103 and is used to limit the movement of the cable 11 in the receiving space 104. It can be understood that when the cable 11 is pulled by the outside, the cable 11 in the junction box 10 will not be subjected to the pulling force, which ensures the fixing effect of the cable 11 in the junction box 10 and prevents poor contact or breakage between the cable 11 and the conductive copper sheet 102 due to the pulling of the cable 11, thereby improving the stability of the wiring assembly 1.

[0067] In some embodiments, the first wire harness 1112 may be a braided copper strip; and / or the second wire harness 1114 may be a braided copper strip.

[0068] In this embodiment, the first wire harness 1112 and / or the second wire harness 1114 are made of braided copper tape, which can improve the conductivity of the cable 11 and ensure the current transmission efficiency of the photovoltaic device 2. The braided copper tape is formed by intertwining multiple fine copper wires to form a flat shape and then pressing it with a roller press. This ensures the stability of the intertwining between the copper wires and also makes the prepared braided copper tape have good flexibility, which helps the cable 11 adapt to different installation environments and is not easy to break when subjected to external force, thus improving the durability of the cable 11.

[0069] In some embodiments, optionally, such as Figure 1 As shown, the output connector 12 includes: a male plug 121, one end of which is connected to the second end of the adapter 114; and a female plug 122, which is plugged into the other end of the male plug 121.

[0070] In this embodiment, the male plug 121 and the female plug 122 form the output connector 12, which facilitates connection with other devices, enabling the photovoltaic device 2 to be quickly and conveniently connected to external electrical equipment, thus improving the convenience and versatility of the device.

[0071] In some embodiments, the output connector 12 may optionally include: a protective sleeve 123, which is fitted over the male plug 121 and located at the connection between the male plug 121 and the adapter 114; and an anti-loss rope 124, one end of which is connected to the male plug 121 and the other end of which is connected to the female plug 122.

[0072] In this embodiment, the protective sleeve 123 is fitted over the male plug 121 and located at the connection between the male plug 121 and the adapter 114, thereby protecting the male plug 121 and the connection between the male plug 121 and the adapter 114 from damage caused by external interference. The protective sleeve 123 can be an insulating protective sleeve, thereby enhancing the insulation performance of the output connector 12 and preventing electric shock accidents. The two ends of the anti-loss rope 124 are respectively connected to the male plug 121 and the female plug 122, which can prevent the female plug 122 from being lost when it is not plugged into the male plug 121.

[0073] In some embodiments, the male plug 121 may be an Anderson male plug, the female plug 122 may be an Anderson female plug, and the protective sleeve 123 may be the outer sheath of the Anderson male plug.

[0074] like Figure 4 and Figure 5 As shown, a second aspect of this application provides a photovoltaic device 2, including a wiring assembly 1 as described in any embodiment of the first aspect.

[0075] The photovoltaic device 2 provided in this application includes the wiring component 1 in any embodiment of the first aspect. Since the photovoltaic device 2 provided in this application includes the wiring component 1 in any embodiment of the first aspect, it also possesses all the beneficial effects of the wiring component 1 in any embodiment of the first aspect, which will not be elaborated further here.

[0076] The wiring assembly 1 and photovoltaic device 2 of this application will be further described below with reference to a specific embodiment.

[0077] A double-strand flat cable includes two parallel flat cable units (body 111). The cable inside each unit is formed by intertwining multiple fine copper wires to create a flat shape, which is then pressed using a roller press. This ensures the stability of the intertwining of the copper wires while maintaining the inherent flexibility of a fine copper wire cable. The number of copper wires can be controlled by adjusting the diameter of the copper wires passing through the cross-sectional area of ​​each unit, thereby adjusting the flexibility of the flat cable. The surface of the cable unit is covered with a soft rubber material (insulating sleeve 112), such as PVC (Polyvinyl Chloride), silicone, or TPU (Thermoplastic Polyurethane), to ensure the insulation performance and flexibility of the cable. The soft rubber surface of the two parallel flat cable units also has openings (grooves 115), allowing them to be separated into two individual cables.

[0078] Cable and Anderson connector assembly: includes flat cable, Anderson connector (output connector 12) and cable SR fastener (fastener 15).

[0079] Flat cable and junction box 10 fixing method and application: including junction box top cover 101, junction box bottom cover 106, conductive copper sheet 102, diode 105, flat cable finished product (cable 11), wire clip (limiting member 16), Anderson adapter (male plug 121) and silicone rope (anti-loss rope 124).

[0080] In related technologies, the wires of solar panels generally use round cables. Because the diameter of round cables is relatively large, the wiring and fixing are greatly restricted by space when the wiring needs to pass through narrow spaces such as car windows in RVs, yachts and other applications.

[0081] Flat cables, due to their thin and flat characteristics, are easy to bend during use, allowing for flexible and versatile cable routing with minimal space constraints, giving them a significant advantage in many special application scenarios.

[0082] This application provides a wiring assembly 1 and a photovoltaic device 2, as well as a connection and fixing method and application: including a finished double-strand flat cable (cable 11), a junction box body (junction box 10), a wire fixing mechanism (fixing member 15), and an adapter (output connector 12).

[0083] like Figure 3 As shown, the dual-strand flat cable (cable 11) includes the following:

[0084] The first wire harness 1112 and the second wire harness 1114 are braided copper strips, and each wire is made of tin-plated copper; the insulating sleeve 112 is wrapped with insulating soft rubber material; the groove 115 is designed with a V-shaped groove, which makes it convenient to separate the double-stranded wire into two single-stranded wires when needed.

[0085] like Figure 2 As shown, the dual-strand flat cable includes the following:

[0086] The cable SR fixing component (fixing component 15), the first buffer component 13 is a bending and softening structure, the Anderson male connector outer sheath (protective sleeve 123), the second buffer component 14 is a bending and softening structure, the waterproof silicone ring, and the Anderson connector (male plug 121).

[0087] like Figure 1 As shown, the finished double-strand flat cable is used in conjunction with the junction box for secure installation, including the following:

[0088] Finished cable (cable 11), junction box lower cover 106, junction box upper cover 101, welded conductive copper sheet 102, diode 105, cable fixing spring clip (limiting part 16), Anderson adapter female connector (female plug 122) and adapter anti-loss silicone rope (anti-loss rope 124).

[0089] Details of cables and junction boxes in their stored state, as shown Figure 4 As shown, the visible appearance of the wiring assembly and photovoltaic panel after overall assembly is as follows. Figure 5As shown.

[0090] The wiring assembly 1 and photovoltaic device 2 provided by this utility model have the following advantages:

[0091] 1. When wiring needs to pass through narrow spaces such as doors and windows, it can pass directly through the gaps without affecting the normal closing and use of the doors and windows.

[0092] 2. Compared with round cables, flat cables have a larger contact area with the mounting carrier, can be fixed with adhesive, are easy to hide, have a smaller height, and have less wind resistance when subjected to dynamic loads.

[0093] 3. The core of this flat cable is made of multiple fine filaments twisted and braided together. The Anderson connectors at both ends and the SR fixing parts (fixing parts 15) of the cable are designed with bending protection, so that it can maintain good flexibility and resilience when stretched.

[0094] 4. Due to its flexibility and pressing process, this flat cable is easy to roll up, takes up less space, and is easier to package and transport.
