[0048] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0049] See also Figure 1 The existing photovoltaic modules are all provided with junction boxes at both ends of the back of the photovoltaic module 10, and the two junction boxes are respectively connected to the positive MC4 terminal 01 and the negative MC4 terminal 02 through cables.

[0050] The positive MC4 terminal 01 and the negative MC4 terminal 02 of the two photovoltaic modules 10 are connected to each other to realize the series connection of the photovoltaic modules.

[0051] See also Figures 2 to 5In the installation scenario of photovoltaic curtain wall layout of building curtain wall, the photovoltaic curtain wall is assembled from multiple photovoltaic curtain wall modules, and the photovoltaic curtain wall module includes photovoltaic components and frames. A large number of frames 03 need to be installed in the process of assembling the photovoltaic curtain wall module into a photovoltaic curtain wall. The positive second junction box of the photovoltaic curtain wall module 10a is equipped with a positive MC4 terminal 01 and a negative MC4 terminal 02. The positive MC4 terminal 01 and the negative MC4 terminal 02 of the two photovoltaic curtain wall modules 10a need to be manually plugged and connected, and the assembly efficiency is low.

[0052] Since the electrical connection point (the point where the positive MC4 terminal 01 and the negative MC4 terminal 02 are plugged in) must not come into contact with the building wall, etc., and in order to prevent the cable from swinging due to the wind, it is necessary to use a wire clip to fix the cable, the positive MC4 terminal 01 and the negative MC4 terminal 02 to the frame 03. In order to facilitate cable connection, the frame 03 is usually set as a hollow structure, and the frame 03 is punched with holes for cable threading. The threading and installation of the cables during the assembly process of the photovoltaic curtain wall module 10a are extremely complicated, and the hole setting for threading on the frame 03 is also relatively complicated. In addition, the frame 03 is a hollow structure or a perforated setting, which may cause water accumulation in the frame 03, affecting the safety of the building curtain wall and photovoltaic products.

[0053] Aiming at at least one of the above technical problems, the utility model discloses a quick-connect plug, a photovoltaic assembly and a photovoltaic curtain wall module.

[0054] See also Figures 3 to 7 The quick-connect plug in this embodiment includes a first plug 100 and a second plug 200 that can be plugged together to achieve electrical connection; the first plug 100 and the second plug 200 both include a socket and a terminal, the socket and the terminal are rigidly connected, and the socket is provided with a mounting portion to achieve the installation of the first plug 100 and the second plug 200.

[0055] The first plug 100 and the second plug 200 of the quick-connect plug of the utility model can be installed on two photovoltaic modules 10 through the mounting part of the socket thereof, and the sockets and terminals of the first plug 100 and the second plug 200 are rigidly connected, so when two photovoltaic modules 10 are spliced, the first plug 100 of one photovoltaic module 10 can be plugged and matched with the second plug 200 of another photovoltaic module 10. The time for additional plugging of the first plug 100 and the second plug 200 can be reduced, thereby improving the assembly efficiency of the photovoltaic modules 10.

[0056] It should be noted that rigid connection is different from flexible connection. In rigid connection, the socket and the terminal can withstand a certain external force and basically no obvious deformation occurs. Flexible connection, such as the connection between the cable and the terminal, will bend and deform when slightly subjected to external force. Since the socket and the terminal are rigidly connected, when plugged in along the predetermined direction, there is basically no deformation between the two.

[0057] like Figure 6 As shown, the first plug 100 includes a first socket 110 and a first terminal 120 disposed at the first socket 110 .

[0058] like Figure 7 As shown, the second plug 200 includes a second socket 210 and a second terminal 220 disposed at the second socket 210 .

[0059] One of the first terminal 120 and the second terminal 220 is a male terminal, and the other is a female terminal, and the male terminal and the female terminal have matching sizes.

[0060] Taking the installation in the photovoltaic assembly 10 as an example, the first plug 100 of the photovoltaic assembly 10 located in the middle is plugged into and matched with the second plug 200 of the previous photovoltaic assembly 10, and the second plug 200 of the photovoltaic assembly 10 located in the middle is plugged into and matched with the first plug 100 of the next photovoltaic assembly 10.

[0061] In some embodiments, the first plug 100 and the second plug 200 have a plugging surface when plugged together; in order to improve the waterproof effect of the quick-connect plug, the second plug 200 is provided with a waterproof portion, and the plugging surface is wrapped by the waterproof portion. It should be noted that the above-mentioned waterproof portion can also be provided on the first plug 100, and the specific structure can refer to the structure of the waterproof portion provided on the second plug 200.

[0062] In some embodiments, the waterproof portion includes a first waterproof portion 222, which is connected to the second socket 210 and surrounds the second terminal 220, and when the second terminal 220 is plugged with the first terminal 120, it wraps around the outer periphery of the plugging surface of the second terminal 220 and the first terminal 120. The first waterproof portion 222 can improve the waterproof performance of the first plug 100 and the second plug 200 when plugged.

[0063] In order to optimize the above solution, the waterproof part may further include a second waterproof part 223, which surrounds the first waterproof part 222 and has a second waterproof annular cavity 224 therebetween. The second waterproof part 223 can provide double waterproofing, thereby further improving the waterproofing performance.

[0064] The second waterproof portion 223 , the first waterproof portion 222 and the second socket 210 are an integrated structure or a split structure.

[0065] One of the first terminal 120 and the second terminal 220 is a male terminal and the other is a female terminal. For example, the second terminal 220 includes a pin 221 and the corresponding first terminal 120 includes a socket.

[0066] In order to facilitate the installation of the first plug 100 and the second plug 200, the first plug 100 further includes a first mounting frame 111, through which the first plug 100 is installed on the photovoltaic module 10, and the second plug 200 further includes a second mounting frame 211, through which the second plug 200 is installed on the photovoltaic module 10. It can be explained that the first mounting frame 111 and the second mounting frame 211 can both be understood as mounting parts, and multiple mounting points can be set on the first mounting frame 111 and the second mounting frame 211.

[0067] In order to further improve the waterproof performance, the quick-connect plug further includes a waterproof cover 500, which is sleeved on the outer periphery of the first terminal 120 to guide water to a location away from the first socket 110. Any structure capable of guiding water away from the first plug 100 can be understood as the waterproof cover 500.

[0068] The waterproof cover 500 includes a waterproof cover 510 and a guide portion 520. The waterproof cover 510 is sleeved on the outer periphery of the first terminal 120, and the guide portion 520 extends from close to the waterproof cover 510 to away from the waterproof cover 510. When the first plug 100 and the second plug 200 are plugged and matched, the waterproof cover 510 is embedded in the second waterproof portion 224. When there is rainy weather, rainwater from the previous photovoltaic module 10 enters the guide portion 520 through the second waterproof portion 223, and the guide portion 520 guides the rainwater to a position away from the first plug 100.

[0069] In order to further improve the waterproof performance, the edge 521 of the guide portion 520 is rolled. Furthermore, the guide portion 520 is tilted downward from the direction close to the waterproof cover to the direction away from the waterproof cover, which can effectively prevent the rainwater that penetrates or enters the heat dissipation cavity from damaging the plug. At the same time, the rolled edge of the waterproof cover 500 is embedded in the upper frame 700, and the rainwater that penetrates the gap between adjacent photovoltaic modules 10 and the rainwater that flows down from the upper photovoltaic module 10 can be drained to both sides by the rolled edge, effectively protecting the plug and the junction box.

[0070] See also Fig.10 The utility model also discloses a photovoltaic assembly 10, including a photovoltaic array panel 700, a first junction box 300, a second junction box 400 and a quick-connect plug as described above, wherein the first junction box 300 and the second junction box 400 are electrically connected to the photovoltaic array panel 700; one of the first plug 100 and the second plug 200 of the quick-connect plug is connected to the first junction box 300, and the other of the first plug 100 and the second plug 200 is connected to the second junction box 400; the first plug 100 and the second plug 200 are both fixed to the photovoltaic array panel 700 through the mounting portion of the socket.

[0071] Since the quick-connect plug has the above beneficial effects, the photovoltaic assembly 10 including the quick-connect plug has corresponding effects, which will not be described in detail here.

[0072] The first plug 100 and the second plug 200 are arranged opposite to each other in a first preset direction, and electrical connection between two adjacent photovoltaic components 10 can be achieved through the first plug 100 and the second plug 200.

[0073] It should be noted that the first preset direction may be the length direction or the width direction of the photovoltaic assembly 10 , so that rapid assembly can be achieved.

[0074] The utility model also discloses a photovoltaic curtain wall module 10a which may include a frame 700 and the photovoltaic assembly 10 as described above. It should be noted that the above photovoltaic curtain wall module 10a is only an example, and the photovoltaic curtain wall module 10a in the embodiment of the utility model includes but is not limited to the above structure, and the photovoltaic curtain wall module 10a in the embodiment of the utility model may also include more or less.

[0075] See also Figures 11 to 15 The photovoltaic curtain wall module 10a may include a frame 700, a light-transmitting component 800, a photovoltaic component 10 and a thermal insulation component, wherein the light-transmitting component 800, the photovoltaic component 10 and the thermal insulation component are sequentially arranged in the frame 700.

[0076] In order to improve the aesthetics of the photovoltaic curtain wall module 10a, the light-transmitting component 800 includes a nano-fluorocarbon decorative coating.

[0077] In some embodiments of the present invention, the thermal insulation component includes a thermal insulation layer 900 and a waterproof membrane, and the waterproof membrane is arranged on a side of the thermal insulation layer 900 close to the photovoltaic component 10 .

[0078] The power generation efficiency is improved by increasing the amount of light absorption, and the heat dissipation efficiency of the photovoltaic module 10 is increased to reduce the heat accumulation of the photovoltaic module 10, thereby improving the power generation efficiency of the photovoltaic module 10.

[0079] In order to facilitate the assembly of the photovoltaic curtain wall module 10a, the frame 700 may include a relatively arranged hanging ear 710 and a hanging hole, and the hanging ear 710 is adapted to the size of the hanging hole. The hanging ear 710 and the frame 700 are an integral structure or a split structure, and the connection of two adjacent photovoltaic curtain wall modules 10a can be achieved through the hanging ear 710. The hanging hole can be set on one of the top side and the bottom side of the frame 700, and the hanging ear 710 is set on the other of the bottom side and the top side of the frame 700. Or the hanging hole can be set on one of the left side and the right side of the frame 700, and the hanging ear 710 is set on the other of the right side and the left side of the frame 700.

[0080] The hanging ear 710 is installed on the frame 700 through the mounting hole.

[0081] In order to facilitate positioning and improve assembly efficiency, the frame 700 may also include relatively arranged positioning pins 720 and positioning holes 730, and the positioning pins 720 and the positioning holes 730 are adapted in size. The positioning of two adjacent photovoltaic curtain wall modules 10a is achieved by the cooperation of the positioning pins 720 and the positioning holes 730. The positioning pins 720 can be set on one of the top side and the bottom side of the frame 700, and the positioning holes 730 are set on the other of the bottom side and the top side of the frame 700. Or the positioning pins 720 can be set on one of the left side and the right side of the frame 700, and the positioning holes 730 are set on the other of the right side and the left side of the frame 700.

[0082] The positioning pins 720 are installed on the frame 700 through the installation holes. The positioning pins 720 and the positioning holes 730 can ensure the flatness and aesthetics of the surfaces of the adjacent photovoltaic curtain wall modules 10a during the assembly process.

[0083] Referring to the figure, the embodiment of the utility model also discloses a photovoltaic curtain wall, which is formed by assembling any of the photovoltaic curtain wall modules 10a described above on a wall.
