Description

Technical Field

[0001] The present invention relates to the technical field of connectors, specifically to photovoltaic module connectors, photovoltaic modules, and photovoltaic facades. Background Art

[0002] A photovoltaic module connector is a component that conducts electrical connection by means of male-female docking and plugging. A photovoltaic module is a device that absorbs solar energy through a photovoltaic panel and converts it into electrical energy. A photovoltaic facade is a building equipped with several photovoltaic modules. During actual construction and use, several photovoltaic modules are installed on the photovoltaic facade, and the converted electrical energy is transmitted to a power storage device for storage through the photovoltaic module connector, forming the entire photovoltaic operation.

[0003] However, the photovoltaic module connector has the following defects during specific use: 1. During actual assembly of the existing photovoltaic module connectors, in order to facilitate the overall assembly and the repair of internal components, the assembly operation of the connector (male head and female head) is generally completed by means of threads and plugging. However, during actual assembly, since it conducts electricity for the photovoltaic modules integrated on the photovoltaic facade, a multi-strand cable is generally used to ensure the safety during the electrical transmission operation. At this time, the cable conductors inside the multi-strand cable are likely to affect their electrical conductivity, load capacity, and heat dissipation effect due to the large transmitted current, thereby affecting the service life of the photovoltaic module connector; 2. When the existing photovoltaic module connectors generally complete the current transmission operation by means of male-female plugging and fixing, during this process, the pin part of the male head will be inserted into the battery cell inside the female head to achieve the current transmission operation. However, when the male head and the female head are plugged, the pins of the male head will squeeze the battery cell inside the female head due to the extrusion force during insertion, and cause the battery cell inside the female head to have an inward moving force, which is likely to squeeze and collide with the conductive elements (metal parts) inside the female head and cause phenomena such as electric sparks, with relatively low safety.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment 1

A multi-strand cable 10 extending to the outside is electrically connected inside the female plug 30. A plurality of conductive pins 200 are electrically connected to the top of the male plug 20, and the conductive pins 200 extend into the inside of the female plug 30. A cable connection and assembly mechanism 40 electrically connected to the multi-strand cable 10 is provided inside the male plug 20 and the female plug 30. The cable connection and assembly mechanism 40 is electrically connected to the conductive pins 200. The cable connection and assembly mechanism 40 includes: a cell assembly component 401 electrically connected to the conductive pins 200; an embedded insulator 402 installed on the side of the cell assembly component 401; a plurality of assembly embedded openings 403 opened inside the embedded insulator 402, and the cell assembly component 401 is embedded inside the assembly embedded openings 403; an outer embedding portion 404 opened at the outer edge of the embedded insulator 402; a snap-fit assembly component 405 connected to the embedded insulator 402 through the outer embedding portion 404, and the multi-strand cable 10 is fixedly assembled inside the snap-fit assembly component 405; a tail sealing component 406 provided outside the snap-fit assembly component 405.

[0020] In the present invention, the male plug 20 includes a tail housing 201 provided outside the tail sealing component 406; a threaded assembly block 202 threadedly connected to the outside of the tail housing 201; a head housing 2021 threadedly connected inside the threaded assembly block 202 and abutting against the side of the tail housing 201; an outer plug 203 installed outside the head housing 2021 and located on the side of the threaded assembly block 202. Among them, the cell assembly component 401 and the embedded insulator 402 are provided inside the head housing 2021, and the snap-fit assembly component 405 is provided inside the tail housing 201; the female plug 30 is assembled and made of the tail housing 201, the threaded assembly block 202 and the head housing 2021. An insertion embedding portion 301 is installed outside the head housing 2021 of the female plug 30, and the outer plug 203 is fixedly inserted inside the insertion embedding portion 301.

[0021] The above working principle: When assembling the male connector 20 and the female connector 30, first pass the multi-strand cable 10 through the tail seal assembly 406 and the snap-fit assembly 405 and extend it to the side of the embedded insulator 402. Then, split the multiple cable conductors inside the multi-strand cable 10 and extend each cable conductor into the assembly insertion port 403 inside the embedded insulator 402. Finally, install the cable conductors of the multi-strand cable 10 into the inside of the battery cell assembly component 401 respectively, completing the connection operation of the male connector 20, the female connector 30 and the multi-strand cable 10. When performing the photovoltaic current transmission operation, through the insertion and fixation of the external plug connector 203 and the insertion and embedding part 301, insert the conductive pin 200 of the male connector 20 into the inside of the female connector 30 to achieve the distribution transmission operation. Among them, the connection and assembly of the battery cell assembly component 401 and the embedded insulator 402 and the connection and assembly of the embedded insulator 402 and the snap-fit assembly 405 are both detachable, which is simple and convenient to operate when maintaining and replacing the components inside the male connector 20 and the female connector 30. And when distributing power, the multiple cable conductors inside the multi-strand cable 10 perform the distribution transmission operation in an independent space, which can improve the conductive performance, load capacity and heat dissipation effect during power distribution, and further improve the service life of the photovoltaic module connector.

[0022] For specific reference Figure 7 , the top of the conductive pin 200 is set to be spherical. The conductive pin 200 extends into the battery cell assembly component 401 inside the female connector 30. A plurality of external protrusions 2001 are installed on the outside of the conductive pin 200, and the external protrusions 2001 match the battery cell assembly component 401 inside the female connector 30.

[0023] In the photovoltaic module connector of the present invention, through the structural design of the external protrusions 2001, it is ensured that when the conductive pin 200 is inserted into the inside of the battery cell assembly component 401 for power distribution, it can be connected one by one in a horizontal insertion manner, reducing the damage degree to the battery cell assembly component 401 and the conductive pin 200 during insertion, and improving the plugging and unplugging times and service life of the photovoltaic module connector.

[0024] For specific reference Figure 6 、 Figure 7 and Figure 9, the battery cell assembly component 401 includes a head insulating sleeve 4011 installed inside the head housing 2021; a plurality of conductive battery cells 4012 installed inside the head insulating sleeve 4011; inner plug connectors 4013 installed on the upper and lower sides outside the head insulating sleeve 4011; guiding support rods 4014 installed on the left and right sides outside the head insulating sleeve 4011, and the guiding support rods 4014 and the inner plug connectors 4013 are arranged alternately. Among them, an embedded battery cell 40121 is assembled on the inner side of the bottom of the conductive battery cell 4012, and the embedded battery cell 40121 extends into the interior of the assembly embedded opening 403. A conductive pin 200 is electrically connected inside the conductive battery cell 4012, and the outer protrusion 2001 outside the conductive battery cell 4012 and the conductive pin 200 are matched.

[0025] In this solution, the inner plug connector 4013 is inserted and fixed inside the inner plug-in part 40131, the inner plug-in part 40131 is installed on the outer side of the embedded insulator 402, and the inner plug-in part 40131 is arranged on the side of the outer embedded part 404. Among them, the guiding support rod 4014 is slidably connected inside the guiding support seat 40141, the guiding support seat 40141 is installed on the outer side of the embedded insulator 402, the guiding support seat 40141 is arranged on the side of the outer embedded part 404, and the guiding support seat 40141 and the inner plug-in part 40131 are arranged alternately.

[0026] In the above solution, through the insertion and fixation of the inner plug connector 4013 and the inner plug-in part 40131, the connection and assembly operation of the head insulating sleeve 4011 and the embedded insulator 402 is realized. The movable connection between the guiding support seat 40141 and the guiding support rod 4014 improves the stability and safety of the head insulating sleeve 4011 and the embedded insulator 402 during connection and assembly.

[0027] In the photovoltaic module connector of the present invention, through the design of a plurality of conductive battery cells 4012, the cable conductors inside the multi-strand cable 10 can be assembled one by one, and each cable conductor inside the multi-strand cable 10 can perform the operation of electrical transmission in an independent space, effectively improving the conductive performance, load capacity and heat dissipation effect during power distribution. At the same time, the design of the embedded battery cell 40121 and the conductive battery cell 4012 can reduce the assembly difficulty while ensuring that current can be transmitted through the two. And when assembling or maintaining and checking the two, the conductive battery cell 4012 located inside the head insulating sleeve 4011 and the embedded battery cell 40121 located inside the embedded insulator 402 can be separated together, reducing the probability of deformation caused by uneven local force on the two.

Among them, the outer protective sleeve 4055 is assembled and fixed inside the tail housing 201. The outer protective sleeve 4055 is arranged on the side of the inner embedding insulator 402, and there is a gap between the inner embedding insulator 402 and the outer protective sleeve 4055. A plurality of strands of cables 10 penetrate through the inside of the outer protective sleeve 4055, and a tail sealing assembly 406 is arranged at the bottom of the outer protective sleeve 4055.

[0029] In the photovoltaic module connector of the present invention, through the design of the outer mounting heads 4051, inner arc arms 4052 and snap - fit heads 4053, the inner embedding insulator 402 can be detachably mounted and fixed on the side of the outer protective sleeve 4055. At the same time, due to the design of the structural shape of the inner arc arms 4052, on the one hand, the occupied space of the inner arc arms 4052 can be reduced, which is convenient for being arranged inside the male plug 20 and the female plug 30. On the other hand, a space is left for the outer protective sleeve 4055 and the inner embedding insulator 402, and this space can be used for the shunt operation of the cable conductors inside the plurality of strands of cables 10.

[0030] Specifically refer to Figure 10 , the tail sealing assembly 406 includes an inner rubber sleeve ring 4061 mounted on the inner side of the bottom of the outer protective sleeve 4055; a tail sealing cover 4062 threadedly connected to the outside of the inner rubber sleeve ring 4061.

Among them, a plurality of strands of cables 10 penetrate through the inside of the inner rubber sleeve ring 4061 and the tail sealing cover 4062.

[0031] In the photovoltaic module connector of the present invention, through the design of the threaded connection between the inner rubber sleeve ring 4061 and the tail sealing cover 4062, the tails of the male plug 20 and the female plug 30 are sealed, reducing the probability of external rainwater, fog, etc. entering the inside of the male plug 20 and the female plug 30, and improving the sealing performance of the male plug 20 and the female plug 30.

Among them, the photovoltaic panels 502 are electrically connected to the male plug 20 through a plurality of strands of cables 10.

[0033] In the photovoltaic module of the present invention, the photovoltaic panel 502 can absorb solar energy, and through the power components inside the photovoltaic panel 502, convert the converted direct current into alternating current. Then, the current is stored in the power storage device through multiple cables 10 and the photovoltaic module connector. Embodiment III

[0034] As an assembly solution for the photovoltaic module connector and the photovoltaic module of the present invention, please refer to Figures 11-13 , a photovoltaic curtain wall including a photovoltaic module connector and a photovoltaic module, includes a metal base 60 installed on the curtain wall through expansion bolts; an L-shaped metal plate 601 installed on the side of the metal base 60 through screws; a vertical metal beam plate 602 installed between two L-shaped metal plates 601 through screws; an assembly steel beam 603 installed inside the vertical metal beam plate 602 and extending outside the vertical metal beam plate 602. Among them, another vertical metal beam plate 602 is installed on the outside of the top of the assembly steel beam 603 through screws, and the two vertical metal beam plates 602 are connected by a metal insertion block 604. The inside of the metal insertion block 604 is penetrated by the assembly steel beam 603. Among them, a plurality of horizontal metal beam plates 605 are installed on the left and right sides of the vertical metal beam plate 602 and the assembly steel beam 603 through screws. The inside of the connection between the horizontal metal beam plate 605 and the vertical metal beam plate 602 is installed with a photovoltaic frame 50 through screws. Among them, a rubber waterproof sleeve 6031 is inlaid inside the vertical metal beam plate 602 and the assembly steel beam 603, and a plug-in female head 30 extending outside the rubber waterproof sleeve 6031 is arranged inside the rubber waterproof sleeve 6031.

[0035] In the photovoltaic curtain wall of the present invention, when assembling the photovoltaic module, first fix the metal base 60 on the curtain wall through expansion bolts, and then assemble and fix the L-shaped metal plate 601, the vertical metal beam plate 602, the assembly steel beam 603, and the horizontal metal beam plate 605 respectively through workpieces to build the frame of the photovoltaic curtain wall. Among them, the assembly steel beam 603 can cooperate with the metal insertion block 604 to assemble and fix multiple vertical metal beam plates 602 in the vertical direction.

Embodiment IV

[0036] On the basis of the above embodiments, it is found during use that when the internal parts of the conductive battery cell 4012 and the embedded battery cell 40121 penetrate through the cable conductors of multiple cables 10, since the male plug 20 and the female plug 30 of the photovoltaic module connector are connected and fixed by plugging, and each time of plugging and unplugging, the conductive pin 200 is inserted into the inside of the conductive battery cell 4012, it is easy to push the conductive battery cell 4012 to move due to the extrusion force. At this time, the conductive battery cell 4012 is in direct contact with the embedded battery cell 40121, and both the conductive battery cell 4012 and the embedded battery cell 40121 are made of metal materials, and electric sparks are likely to be generated due to extrusion and collision between the two, resulting in low safety when performing photovoltaic operations during plugging and unplugging.

[0037] Therefore, specifically referring to Figure 14 , an insulating embedding block 70 is provided at the connection between the conductive battery cell 4012 and the embedded battery cell 40121. The cross-sectional area of the insulating embedding block 70 on the side close to the embedded battery cell 40121 is smaller than the cross-sectional area on the side close to the conductive battery cell 4012. A straight groove 701 is formed in the inner wall of the insulating embedding block 70 on the side close to the conductive battery cell 4012. A battery cell protrusion 702 installed outside the conductive battery cell 4012 is movably connected inside the straight groove 701. The length of the straight groove 701 is greater than the length of the battery cell protrusion 702. The cable conductors of multiple cables 10 penetrate through the insulating embedding block 70.

[0038] In the photovoltaic module connector of the present invention, through the design of the insulating embedding block 70, on the one hand, it can protect the connection between the conductive battery cell 4012 and the embedded battery cell 40121, avoiding the conductive pin 200 from inserting into the conductive battery cell 4012 and causing the conductive battery cell 4012 to squeeze or collide with the embedded battery cell 40121, reducing the probability of generating electric sparks due to collision, and improving the safety of power distribution and transmission operations; on the other hand, it can increase the friction force and pre-tightening force, effectively preventing the connection part from loosening during operation, thereby ensuring the stability of the connection, and can also ensure good contact at the connection of the conductive battery cell 4012, reducing the contact resistance, and thus improving the conductivity.
