[0046] In the description of the present application, “plurality” means two or more than two, unless otherwise precisely and specifically specified.
[0047] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0048] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.
[0049] As mentioned in the background technology, the MC4 plug in the related technology is partially exposed outdoors and is often affected by wind, rain, humidity and other environments, which may cause water or moisture to enter the MC4 plug, resulting in MC4 plug failure.
[0050] Multi-Contact, 4mm plug, also known as MC4 plug, is a photovoltaic connector, mainly composed of two parts: metal parts and insulating parts. It is used to connect various components in solar photovoltaic systems, including solar panels, junction boxes, inverters and other important components. It is responsible for safely and efficiently transmitting the electrical energy generated by photovoltaic components to photovoltaic cables.
[0051] Correct installation and use of MC4 plugs can ensure the normal operation of photovoltaic power stations, while reducing power loss and improving power generation efficiency. In existing solar photovoltaic systems, MC4 plugs are usually tied to the photovoltaic brackets of photovoltaic modules after connecting photovoltaic cables and photovoltaic modules. Photovoltaic brackets are usually exposed to outdoor environments, causing MC4 plugs to be frequently affected by wind, rain, humidity and other environmental factors, causing water to enter or become damp inside the MC4 plug. Moisture can cause oxidation of metal parts inside the MC4 plug, thereby increasing contact resistance and affecting the transmission efficiency of current. Or, because moisture is a conductor, it may cause a short circuit inside the MC4 plug, causing damage to the MC4 plug or even a fire.
[0052] Based on the above technical problems, an embodiment of the present application provides a protective device for a photovoltaic module connector. In this technical solution, the protective device for the photovoltaic module connector includes a protective member and a drying member. The protective member has an installation cavity, which is used to place an MC4 plug so that the protective member is sleeved on the outer peripheral side of the MC4 plug. Both ends of the protective member have connecting holes, which are used to place the connecting wires of the MC4 plug. The drying member is arranged on the inner wall of the installation cavity, and is used to absorb moisture in the installation cavity.
[0053] In this way, the protective part is used to provide the first layer of protection for the MC4 plug to prevent the MC4 plug from being damaged by collision due to external force and to block external wind and rain from contacting the MC4 plug. The drying component is used to absorb the moisture in the installation cavity. It can be understood that when there is long-term wind and rain outside, some moisture enters the installation cavity and can be absorbed by the drying component, which is equivalent to providing a second layer of protection for the MC4 plug, further preventing moisture from corroding the MC4 plug, and solving the problem that the MC4 plug is exposed to the outdoors when in use and is affected by wind, rain, humidity and other environments, resulting in a high failure rate of the MC4 plug.
[0054] It should be noted that Figures 1 to 5 The schematic diagram of each component in the protective device of the photovoltaic module connector is shown. The specific structure of the remaining components in the protective device of the photovoltaic module connector is not limited to Figures 1 to 5 of examples.
[0055] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:
[0056] Reference Figure 1 and Figure 2 As shown, a protective device for a photovoltaic module connector provided in an embodiment of the present application is used to protect an MC4 plug 300 . The protective device for the photovoltaic module connector includes: a protective member 100 and a drying assembly 200 .
[0057] The protective member 100 has an installation cavity 101 therein, and the installation cavity 101 is used to place the MC4 plug 300 so that the protective member 100 is sleeved on the outer peripheral side of the MC4 plug 300 .
[0058] Both ends of the protective member 100 have connection holes 102 , and the connection holes 102 are used to place the connection wires at both ends of the MC4 plug 300 respectively.
[0059] The drying component 200 is disposed in the installation cavity 101 , and is used to absorb moisture in the installation cavity 101 .
[0060] In the above embodiment, the protective member 100 is firstly sleeved on the outer peripheral side of the MC4 plug 300, and the connecting wires at both ends of the MC4 plug 300 are respectively inserted into the connecting holes 102. The protective member 100 provides the first layer of protection for the MC4 plug 300, preventing the MC4 plug 300 from being damaged by collision due to external force and preventing external wind and rain from contacting the MC4 plug 300, and the drying component 200 is used to absorb the moisture in the installation cavity 101.
[0061] It is understandable that during the long-term use of the MC4 plug 300, some moisture in the external environment will inevitably enter the installation cavity 101. When some moisture in the external environment enters the installation cavity 101, it can be absorbed by the drying component 200, which is equivalent to providing a second layer of protection for the MC4 plug 300, further preventing moisture from corroding the MC4 plug 300, and solving the problem of the high failure rate of the MC4 plug 300 caused by the MC4 plug 300 being exposed to the outdoors during use and being affected by wind, rain, humidity and other environments.
[0062] In a possible embodiment, the protective member 100 includes a first protective shell 110, a second protective shell 120 and a hinge shaft 130. The first protective shell 110 and the second protective shell 120 are connected via the hinge shaft 130. The first protective shell 110 and the second protective shell 120 are jointly arranged to form an installation cavity 101. The first protective shell 110 and the second protective shell 120 control the opening and closing of the installation cavity 101 by flipping.
[0063] In the above embodiment, the installation cavity 101 can be opened and closed by flipping the first protective shell 110 and the second protective shell 120. The staff can open the installation cavity 101 by flipping the first protective shell 110 and the second protective shell 120, and then install the MC4 plug 300. The installation cavity 101 can be closed by flipping the first protective shell 110 and the second protective shell 120 in the opposite direction, which has the effect of simple operation and improved installation efficiency.
[0064] Here, the two connection holes 102 at both ends of the protective member 100 may be opened on one of the first protective shell 110 and the second protective shell 120, or the first protective shell 110 and the second protective shell 120 may each open a connection hole 102, or the first protective shell 110 and the second protective shell 120 may each open a semi-arc connection hole 102, such as Figure 1 As shown, when the first protective shell 110 and the second protective shell 120 are turned over to close the installation cavity 101, the semi-arc-shaped connecting holes 102 facing each other form a complete arc connecting hole 102. The opening position of the connecting hole 102 is not limited here.
[0065] Continue to refer to Figure 1 and Figure 2 As shown, in a possible implementation manner, the protective element 100 further includes a snap-on assembly 140 .
[0066] The clamping assembly 140 includes a clamping joint 141 and a clamping ring 142 . One of the first protective shell 110 and the second protective shell 120 has the clamping joint 141 , and the other has the clamping ring 142 . The clamping joint 141 and the clamping ring 142 are correspondingly clamped.
[0067] Here, when the staff opens and closes the installation cavity 101, the first protective shell 110 and the second protective shell 120 can be opened and closed by the clamping joint 141 and the clamping ring 142, which has the effects of simple structure and easy operation.
[0068] It should be noted that Figure 1 and Figure 2 As shown in the figure, the first protective shell 110 has a clamping ring 142, and the second protective shell 120 has a clamping joint 141. Of course, the first protective shell 110 can also have a clamping joint 141, and the second protective shell 120 can have a clamping ring 142. Here, there is no restriction on the positions of the clamping ring 142 and the clamping joint 141, as long as the opening and closing of the first protective shell 110 and the second protective shell 120 can be controlled.
[0069] In one possible implementation, refer to Figure 1 , Figure 3 and Figure 4 As shown, the drying assembly 200 includes a mounting box 210 and a drying block 220 .
[0070] The inner wall of the installation cavity 101 has an installation groove 103, and the installation box 210 is inserted into the installation groove 103. The installation box 210 has at least one air hole 211 on the side facing the installation cavity 101. The drying block 220 is placed in the installation box 210 to absorb moisture in the installation cavity 101 through the air hole 211.
[0071] In the above embodiment, the drying block 220 in the installation box 210 can absorb moisture in the installation cavity 101 through the air vent 211, and the installation box 210 is inserted into the installation slot 103 to achieve a detachable connection between the installation box 210 and the installation slot 103, which is convenient for replacing the installation box 210 and the drying block 220, and can further prevent moisture in the installation cavity 101 from corroding the MC4 plug 300, thereby preventing the MC4 plug 300 from malfunctioning.
[0072] When implementing it, refer to Figure 3 and Figure 4 As shown, there are at least two installation grooves 103 on the inner wall of the installation cavity 101, and an installation box 210 is inserted in each installation groove 103. Setting the number of installation boxes 210 to multiple helps to further improve the efficiency of absorbing moisture in the installation cavity 101, further improve the safety of the MC4 plug 300, and reduce the failure rate.
[0073] Here, the plurality of mounting grooves 103 are evenly distributed along the inner wall of the mounting cavity 101 .
[0074] Alternatively, the plurality of vent holes 211 formed on the side of the installation box 210 facing the installation cavity 101 are evenly distributed along the side wall of the installation box 210, thereby increasing the effective area of the drying block 220, improving the water absorption efficiency, and further improving the drying effect.
[0075] In other possible implementations, the drying block 220 may be a diatomaceous earth drying bar or a silica gel drying block 220 , and the specific structure of the drying block 220 is not limited.
[0076] In a possible embodiment, in order to improve the stability of the installation box 210 inserted in the installation groove 103, the side wall of the installation groove 103 has at least one first plug-in portion, and the outer side wall of the installation box 210 has at least one second plug-in portion, and the first plug-in portion is plugged into the second plug-in portion accordingly.
[0077] One of the first plug-in portion and the second plug-in portion is a plug-in block 230 , and the other of the first plug-in portion and the second plug-in portion is a plug-in slot 212 . The plug-in block 230 is plugged in a one-to-one correspondence with the plug-in slot 212 .
[0078] Further, see Figure 4 As shown, the side wall of the mounting groove 103 has a plug-in block 230, and the outer wall of the mounting box has a plug-in groove 212. Of course, the side wall of the mounting groove 103 may also have a plug-in groove 212, and the outer wall of the mounting box may have a plug-in block 230, and there is no limitation here.
[0079] At least one plug-in slot 212 is provided on two opposite sides of the installation box 210 , and at least one plug-in block 230 is provided on two opposite side walls of the installation slot 103 , which helps to provide multiple force points for the installation box 210 and further improve the stability of the installation box 210 .
[0080] In one possible implementation, refer to Figure 4 As shown, the drying component 200 further includes an adhesive 240 , which is connected to the bottom side of the installation box 210 , or the adhesive 240 is connected to the inner bottom wall of the installation groove 103 , and the installation box 210 is bonded to the inner bottom wall of the installation groove 103 through the adhesive 240 .
[0081] In the above embodiment, the adhesive member 240 connects the bottom side of the installation box 210 and the inner bottom wall of the installation slot 103 , further improving the stability of the installation box 210 and preventing the installation box 210 from falling out of the installation slot 103 .
[0082] Here, the adhesive 240 can be a double-sided adhesive strip with adhesiveness or a magnetic sticker with magneticness. It only needs to connect the bottom side of the installation box 210 and the inner bottom wall of the installation groove 103. There is no limitation on the specific structure of the adhesive 240.
[0083] In other possible implementations, refer to Figure 4 and Figure 5 As shown, there is a gap between the side wall of the installation box 210 facing the installation cavity 101 and the inner wall of the installation cavity 101 .
[0084] It is understandable that the MC4 plug 300 has a variety of different specifications, and its overall external dimensions are different. When the MC4 is installed in the installation cavity 101, part of the outer wall of the MC4 abuts against the inner wall of the installation cavity 101. If part of the outer wall of the MC4 abuts against the side wall of the installation box 210 facing the installation cavity 101, the air vent 211 will be blocked, affecting the water absorption efficiency. By providing a gap between the side wall of the installation box 210 facing the installation cavity 101 and the inner wall of the installation cavity 101, the area where the outer wall of the MC4 plug 300 abuts against the side wall of the installation box 210 can be reduced, thereby reducing the blockage of the air vent 211, or the outer wall of the MC4 plug 300 is not abutted against the side wall of the installation box 210, which helps to improve the water absorption efficiency of the drying block 220.
[0085] In one possible implementation, refer to Figure 1 , Figure 3 and Figure 4As shown, the protective device of the photovoltaic module connector also includes a sealing component, and the sealing component includes a sealing groove 400 and a sealing strip 500. One of the first protective shell 110 and the second protective shell 120 has a sealing groove 400 arranged along the circumference of the installation cavity 101, and the other has a sealing strip 500 arranged along the circumference of the installation cavity 101. When the installation cavity 101 is closed, the sealing strip 500 is inserted into the sealing groove 400 to close the installation cavity 101, and the sealing strip 500 is interference-fitted with the sealing groove 400.
[0086] Attached Figure 1 It is shown that the first protective shell 110 has a sealing groove 400 and the second protective shell 120 has a sealing strip 500 . Of course, the first protective shell 110 may also have a sealing strip 500 and the second protective shell 120 may have a sealing groove 400 .
[0087] Specifically, the sealing strip 500 can be a sealing strip 500 made of rubber material. The rubber material has good flexibility and sealing properties. After the installation cavity 101 is closed, the interference fit between the sealing strip 500 and the sealing groove 400 can further improve the sealing properties and effectively prevent external moisture from entering the interior of the installation cavity 101.
[0088] Here, the protective device of the photovoltaic module connector also includes a seal 600, which is arranged between the connecting wire and the connecting hole 102 to close the gap between the connecting hole 102 and the connecting wire. The seal 600 can be made of rubber material, and the seal 600 can further improve the sealing of the connecting hole 102 to prevent external moisture from entering the installation cavity 101 through the connecting hole 102.
[0089] In addition, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, both ends of the protective member 100 have extended edges 700, and the extended edges 700 are arranged toward the outside of the protective member 100. Specifically, both ends of the first protective shell 110 and the second protective shell 120 have extended edges 700, and the shape of the extended edges 700 matches the outer peripheral side of the first protective shell 110 and the second protective shell 120. The extended edges 700 can prevent external impurities or moisture from directly flushing into the connecting hole 102, which can further protect the MC4 plug 300 and improve the cleanliness of the installation cavity 101.
[0090] The implementation principle of a protective device for a photovoltaic module connector provided in an embodiment of the present application is as follows: the protective device for the photovoltaic module connector includes a protective member 100 and a drying member 200, the protective member 100 has an installation cavity 101, the installation cavity 101 is used to place the MC4 plug 300, so that the protective member 100 is sleeved on the outer peripheral side of the MC4 plug 300, both ends of the protective member 100 have connecting holes 102, the connecting holes 102 are used to place the connecting wires of the MC4 plug 300, the drying member 200 is arranged on the inner wall of the installation cavity 101, and the drying member 200 is used to absorb moisture in the installation cavity 101.
[0091] In this way, the protective part 100 is used to provide the first layer of protection for the MC4 plug 300 to prevent the MC4 plug 300 from being damaged by collision due to external force and to block external wind and rain from contacting the MC4 plug 300. The drying component 200 is used to absorb moisture in the installation cavity 101. It can be understood that when there is long-term wind and rain from the outside, some moisture enters the installation cavity 101 and can be absorbed by the drying component 200, which is equivalent to providing a second layer of protection for the MC4 plug 300, further preventing moisture from corroding the MC4 plug 300, and solving the problem that the MC4 plug 300 is exposed to the outdoors during use and is affected by wind, rain, humidity and other environments, resulting in a high failure rate of the MC4 plug 300.
[0092] Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein.
