Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a photovoltaic junction box and a photovoltaic module. Background Technology

[0002] Currently, the fixed-length external wires of photovoltaic junction boxes easily interfere with barcodes or nameplates, causing them to shift or become wrinkled, requiring manual adjustment. Improperly positioned wires drooping over the frame take up space, hindering packaging and transportation, and requiring manual straightening. The fixed wire installation methods are insufficient to meet the needs of different installation sites, increasing construction complexity and cost. Therefore, current photovoltaic junction boxes suffer from inconvenient labeling, difficulties in packaging and transportation, and difficulty in adapting to installation requirements. Utility Model Content

[0003] Therefore, it is necessary to provide a photovoltaic junction box and photovoltaic module to address the problems of inconvenient labeling, unfavorable packaging and transportation, and difficulty in adapting to installation requirements of current photovoltaic junction boxes.

[0004] Firstly, a photovoltaic junction box includes:

[0005] The junction box includes a first insulating body and a first conductive terminal, the first insulating body being sleeved over the first conductive terminal, and the first insulating body having a groove recessed along the side opposite to the first conductive terminal; and

[0006] The wire includes a second insulating body and a second conductive terminal. The second insulating body is sleeved on the outside of the second conductive terminal. The second insulating body has a protrusion protruding along the side opposite to the second conductive terminal. The second insulating body is used to be detachably inserted between the first insulating body and the first conductive terminal so that the protrusion and the groove are engaged. The second conductive terminal is sleeved on the outside of the first conductive terminal.

[0007] In one embodiment, the second insulating body includes a limiting portion and a retaining portion sleeved outside the second conductive terminal. The retaining portion is disposed at the end of the limiting portion and has the protrusion. The retaining portion is used to be inserted between the first insulating body and the first conductive terminal, and the limiting portion is used to abut against the end of the first insulating body.

[0008] In one embodiment, the locking post portion includes a plurality of locking posts, all of which are disposed at the end of the limiting portion and are spaced apart around the outer periphery of the second conductive terminal, and each locking post has a protrusion at one end away from the limiting portion.

[0009] In one embodiment, one end of the retaining post, away from the limiting portion, protrudes beyond the second conductive terminal along the length of the wire.

[0010] In one embodiment, the protrusion has a guide surface facing away from the second conductive terminal, the guide surface is inclined, and the side of the guide surface away from the limiting portion is closer to the second conductive terminal than the side of the guide surface closer to the limiting portion.

[0011] In one embodiment, the photovoltaic junction box further includes a cover body, the cover body including a baffle and a connector, the connector being disposed on the baffle and used for insertion between the first insulating body and the first conductive terminal, and the baffle being used for abutting against the end of the first insulating body.

[0012] In one embodiment, the junction box further includes a box body, the first insulating body is disposed at the end of the box body, and the first conductive terminal is electrically connected to the box body.

[0013] In one embodiment, the box body includes a housing and an electrical connection assembly housed within the housing, the first insulating body being disposed at an end of the housing, the electrical connection assembly being electrically connected to the first conductive terminal, and the electrical connection assembly being used for electrically connecting a busbar.

[0014] In one embodiment, the housing body further includes a diode housed within the housing, the diode being electrically connected to the electrical connection assembly.

[0015] In a second aspect, a photovoltaic module includes a photovoltaic junction box as described in the first aspect.

[0016] In the aforementioned photovoltaic junction box, the second insulating body of the wire is detachably inserted between the first insulating body and the first conductive terminal, thus making the wire and junction box detachable. When the second insulating body is inserted between the first insulating body and the first conductive terminal, the protrusion engages with the groove; when the second insulating body is pulled out, the protrusion separates from the groove. This pluggable connection method allows the wire to be separated from the junction box before the photovoltaic module marking process, avoiding interference with the barcode or nameplate placement and eliminating the need for manual adjustment of the wire position for marking. Because the wire is pluggable, it can be removed from the junction box before packaging and transportation, preventing it from drooping onto the photovoltaic module frame area, significantly reducing physical space occupation, improving packaging compactness and efficiency, and eliminating the need for manual guidance of the wire position, facilitating operation. This photovoltaic junction box allows for the selection of appropriate wire lengths based on the actual needs of the installation site, and then connecting them to the box, instead of using fixed-length wires as in traditional non-removable designs. This avoids the incompatibility caused by fixed wire lengths in different installation scenarios, reduces the complexity of wire length considerations during the design phase, and eliminates the need for additional measures such as adding extension lines on-site, thus reducing construction complexity and costs.

Detailed Implementation

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] During the labeling process of photovoltaic modules, the photovoltaic junction box has a fixed-length external wire that may occupy or approach the designated position for attaching barcodes or nameplates, causing barcode misalignment or wrinkles, affecting identification accuracy, and requiring manual adjustment of the wire position. If the installation position of the photovoltaic junction box and its external wire is not carefully planned, the wire may droop into the module frame area, increasing physical space occupation, causing inconvenience for packaging, transportation, and installation, and reducing packaging compactness and efficiency. Typically, the wire needs to be manually guided to the inside of the frame or designated area to complete packaging smoothly. Furthermore, the fixed length of the external wire of the photovoltaic junction box makes it difficult to flexibly adapt to the specific needs of different installation sites, leading to increased construction complexity and costs.

[0025] Please see Figure 1 Based on the above-mentioned problems, in a first aspect, embodiments of this application provide a photovoltaic junction box 100. The photovoltaic junction box 100 includes a junction box 1 and conductors 2. Please refer to... Figure 2 The junction box 1 includes a first insulating body 12 and a first conductive terminal 13. The first insulating body 12 is sleeved on the outside of the first conductive terminal 13. The first insulating body 12 has a recessed groove on the side opposite to the first conductive terminal 13. Figure 2 (Not shown in the image). Please refer to [link / reference]. Figure 3The conductor 2 includes a second insulating body 21 and a second conductive terminal 22. The second insulating body 21 is sleeved over the second conductive terminal 22. The second insulating body 21 has a protrusion 2132 protruding along the side opposite to the second conductive terminal 22. The second insulating body 21 is detachably inserted between the first insulating body 12 and the first conductive terminal 13, so that the protrusion 2132 and the groove are engaged. The second conductive terminal 22 is sleeved over the first conductive terminal 13. It can be understood that the second insulating body 21 is inserted between the first insulating body 12 and the first conductive terminal 13 to engage the groove and the protrusion 2132. The second insulating body 21 is pulled out from between the first insulating body 12 and the first conductive terminal 13 to separate the groove and the protrusion 2132. The junction box 1 and the conductor 2 are detachably connected, allowing the conductor 2 to be separated from the junction box 1 during the photovoltaic module marking process. This avoids interference from the conductor 2 with the barcode or nameplate affixing position and eliminates the need for manual adjustment of the conductor 2's position to accommodate the marking operation. Because wire 2 is pluggable, it can be removed from junction box 1 before packaging and transportation, preventing it from drooping onto the photovoltaic module frame area. This significantly reduces physical space occupation, improves packaging compactness and efficiency, and eliminates the need for manual guidance of wire 2, facilitating operation. The photovoltaic junction box 100 allows for the selection of appropriate wire 2 lengths based on the actual needs of the installation site, connecting it to junction box 1 instead of using fixed-length wire 2 as in traditional non-removable designs. This avoids incompatibility in different installation scenarios caused by a fixed wire 2 length, reduces complex considerations regarding wire 2 length during the design phase, and eliminates the need for additional measures such as adding extension cables on-site, thus reducing construction complexity and cost.

[0026] The structure of junction box 1 will be explained in detail below: Please refer to... Figure 2 In an optional embodiment, the first insulating body 12 may be a cylinder with a hollow portion, or the first insulating body 12 may be a frustum or similar shape with a hollow portion. The first conductive terminal 13 is disposed within the hollow portion of the first insulating body 12.

[0027] In an optional embodiment, the groove may be radially surrounding the first insulating body 12. In other optional embodiments, the groove may be axially positioned on the first insulating body 12 along the first conductive terminal 13. In still other optional embodiments, the groove may be spirally positioned on the first insulating body 12; in other words, in this configuration, the groove has both an axial portion along the first conductive terminal 13 and a radially circumferential portion.

[0028] In a preferred embodiment, the groove is continuously circumferentially surrounding the first insulating body 12 along the radial direction of the first conductive terminal 13. In other words, the groove starts from a point on the inner surface of the first insulating body 12, extends continuously along the circumferential direction, and finally coincides with the starting point, completely surrounding the entire inner circumference of the first insulating body 12. This increases the connection area between the groove and the protrusion 2132, improves the connection stability between the two, and also improves the ease of engagement between the protrusion 2132 and the groove, so that the protrusion 2132 can be engaged into the groove from any direction along the radial direction of the first conductive terminal 13.

[0029] Please see Figure 2 In some embodiments, the junction box 1 further includes a box body 11, a first insulating body 12 disposed at the end of the box body 11, and a first conductive terminal 13 electrically connected to the box body 11. The box body 11 is used to accommodate the electrical connection assembly 112 and the diode 113. It is understood that the box body 11 has a receiving cavity that communicates with the first insulating body 12, and the first conductive terminal 13 is electrically connected to the electrical connection assembly 112 inside the box body 11.

[0030] Please see Figure 2 In some embodiments, the housing body 11 includes a shell 111 and an electrical connection assembly 112 housed within the shell 111. A first insulating body 12 is disposed at the end of the shell 111. The electrical connection assembly 112 is electrically connected to a first conductive terminal 13 and is used to electrically connect a busbar. The busbar is welded to the solder strip on the battery cell and is used to transmit the current generated by the battery cell. The electrical connection assembly 112 is used to deliver the current transmitted by the busbar to the first conductive terminal 13. The first conductive terminal 13 transmits the current to the second conductive terminal 22 of the wire 2, and the wire 2 transmits the current to external devices such as inverters or combiner boxes.

[0031] In an optional embodiment, the electrical connection assembly 112 includes a conductive element and solder, with the solder disposed on the conductive element. High-temperature welding melts the solder, thereby welding the conductive element to the busbar. Both the conductive element and the solder may be made of materials such as tin or silver.

[0032] Please see Figure 2 In some embodiments, the housing 11 further includes a diode 113 housed within the housing 111, the diode 113 being electrically connected to the electrical connection assembly 112. The diode 113 has unidirectional conductivity, and its placement within the housing 11 prevents reverse current from flowing through the photovoltaic module.

[0033] In an alternative embodiment, the box body 11 may be potted and sealed for insulation, or the box body 11 may not be potted.

[0034] Please see Figure 4In some embodiments, the photovoltaic junction box 100 further includes a cover body 3, which includes a baffle 31 and a connector 32. The connector 32 is disposed on the baffle 31 and is used to be inserted between the first insulating body 12 and the first conductive terminal 13. The baffle 31 is used to abut against the end of the first insulating body 12. By providing the cover body 3, the first conductive terminal 13 can be protected without using the wire 2, and the first conductive terminal 13 can be prevented from being damaged by foreign objects.

[0035] The specific structure of conductor 2 will be described below. Please refer to [link / reference]. Figure 3 In some embodiments, the second insulating body 21 includes a limiting portion 212 and a retaining portion 213 sleeved outside the second conductive terminal 22. The retaining portion 213 is disposed at the end of the limiting portion 212 and has a protrusion 2132. The retaining portion 213 is used for insertion between the first insulating body 12 and the first conductive terminal 13 (see [reference]). Figure 2 The limiting part 212 is used to abut against the end of the first insulating body 12 (see [link]). Figure 2 The limiting part 212 abuts against the end of the first insulating body 12, enabling precise control of the insertion depth of the wire 2 into the junction box 1. The limiting part 212 prevents over-insertion. Without it, the wire 2 might be over-inserted during installation, causing problems with the connection between the second conductive terminal 22 and the first conductive terminal 13, such as a connection that is too loose or too tight, or even damaging the first conductive terminal 13. The limiting part 212 provides an installation positioning reference; operators can easily determine whether the wire 2 is properly installed by observing whether the limiting part 212 is in contact with the end of the first insulating body 12.

[0036] Please see Figure 3 In some optional embodiments, the second insulating body 21 further includes a wire portion 214 sleeved around the second conductive terminal 22. The wire portion 214 is located at the end of the limiting portion 212 opposite to the retaining post portion 213, and the radial dimension of the wire portion 214 is smaller than the radial dimension of the limiting portion 212. It is understood that the limiting portion 212 is a link protruding between the retaining post portion 213 and the wire portion 214. A wire electrically connected to the second conductive terminal 22 is disposed within the wire portion 214.

[0037] In an optional embodiment, the line section 214 can be electrically connected to an external device such as an inverter or combiner box via an external plug. In an optional embodiment, the external plug can be an MC4 plug, an MC3 plug, or a Tyco plug, etc.

[0038] Please see Figure 3In some embodiments, the locking post portion 213 includes multiple locking posts 2131, all of which are located at the end of the limiting portion 212 and are spaced apart around the outer periphery of the second conductive terminal 22. Each locking post 2131 has a protrusion 2132 at one end away from the limiting portion 212. The multiple locking posts 2131 spaced apart around the outer periphery of the second conductive terminal 22 provide support and positioning from multiple angles when all of them are inserted between the first insulating body 12 and the first conductive terminal 13. For example, if there is only one locking post 2131 during insertion, the position of the locking post 2131 may easily shift, leading to unstable connection. Multiple locking posts 2131 can cooperate to ensure more accurate insertion, allowing the protrusion 2132 to better engage with the groove on the first insulating body 12, thereby enhancing the stability of the connection between the wire 2 and the junction box 1. In the actual use of the photovoltaic junction box 100, it may be subjected to various external forces, such as vibration and pulling. Multiple locking posts 2131 can evenly distribute these external forces across each locking post 2131, with each locking post 2131 bearing a portion of the force. Compared to a single locking post 2131 bearing all the external forces, multiple locking posts 2131 can effectively reduce the stress borne by each locking post 2131, reduce the risk of damage to the locking posts 2131 or the protrusion 2132 falling out of the groove, and ensure the reliability of the connection.

[0039] In an optional embodiment, the end of the retaining post 213 away from the limiting part 212 is flush with the end of the second conductive terminal 22 along the length direction of the wire 2. Alternatively, the end of the second conductive terminal 22 protrudes from the end of the retaining post 213 away from the limiting part 212 along the length direction of the wire 2. Or, preferably, please refer to [reference needed]. Figure 3 In some embodiments, the end of the retaining post 213 away from the limiting part 212 protrudes beyond the second conductive terminal 22 along the length of the conductor 2. When the end of the retaining post 213 away from the limiting part 212 protrudes beyond the second conductive terminal 22, and the second insulating body 21 is inserted into the first insulating body 12, the engagement of the protrusion 2132 and the groove can precede the engagement of the second conductive terminal 22 and the first conductive terminal 13. This avoids the situation where the second conductive terminal 22 and the first conductive terminal 13 are engaged before the groove and the protrusion 2132 are engaged, making the connection between the conductor and the junction box 1 more stable and reliable. In addition, the protruding retaining post 213 can protect the second conductive terminal 22, reducing damage to the second conductive terminal 22.

[0040] Please see Figure 3 The number of locking posts 2131 is not limited in this application embodiment. For example, there may be two, three, four, five, six, seven, ten, twelve, or other numbers of locking posts 2131. Correspondingly, there may be two, three, four, five, six, seven, ten, twelve, or other numbers of protrusions 2132.

[0041] In an optional embodiment, all protrusions 2132 on all the locking posts 2131 are engaged in an annular groove in the first insulating body 12.

[0042] Please see Figure 3 In some embodiments, the protrusion 2132 has a guide surface 2133 facing away from the second conductive terminal 22. The guide surface 2133 is inclined, and the side of the guide surface 2133 away from the limiting portion 212 is closer to the second guide terminal than the side of the guide surface 2133 near the limiting portion 212. Providing a guide surface 2133 on the protrusion 2132 facilitates the engagement of the protrusion 2132 and the groove, making the engagement of the protrusion 2132 and the groove more convenient.

[0043] Secondly, embodiments of this application also provide a photovoltaic module. This photovoltaic module includes the photovoltaic junction box 100 as described in the first aspect. The photovoltaic module also includes solar cells, a backsheet, a frame, and other structures. The photovoltaic junction box 100 is bonded to the backsheet with an adhesive.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
