[0028] The following clearly and completely describes the technical solutions of the embodiments of the present invention in combination with the drawings of the embodiments of the present invention, and the described embodiments are not all the embodiments, but only some of the embodiments of the present invention. Based on the embodiments of the present invention, on the premise that a person skilled in the art does not make any inventive efforts, all other embodiments obtained fall within the protection scope of the present invention.

[0029] 2, a photovoltaic power generation connector provided by an embodiment of the present invention includes a socket 100 and a plug 200 that is inserted into the socket 100. Here, the plug 200 is inserted into the socket 100 to realize an electrical connection between the plug 200 and the socket 100.

[0030] 22, the outlet 100 is mounted in an electrical device case 300. To facilitate maintenance, the outlet 100 is removably mounted in the case 300. Specifically, the outlet 100 is removably mounted in the case 300 by a fastener, and the outlet 100 is provided with a fixing hole 112 through which the fastener passes.

[0031] The plug 200 is provided with at least one photovoltaic power generation cable 240 , which is electrically connected to the outlet 100 .

[0032] In the above solar power generation connector, at least two plugs 200 are inserted into the outlet 100 and / or at least one plug 200 has at least two solar power generation cables 20 .

[0033] When at least two plugs 200 are inserted into the outlet 100, the outlet 100 corresponds to at least two plugs 200, which effectively reduces the number of outlets 100 compared to the prior art where each outlet corresponds to a plug, and further reduces the required installation area for the outlets 100, i.e., the area occupied by the outlets 100 in the case 300, and further reduces the overall size of the case 300. Furthermore, reducing the number of outlets 100 simplifies installation of the photovoltaic power generation connector and improves installation efficiency, and reducing the number of outlets 100 reduces the cost of the outlets 100 and further reduces the overall cost of the photovoltaic power generation connector.

[0034] If at least one plug 200 has at least two photovoltaic cables 240, compared with one photovoltaic cable provided for each plug in the prior art, the number of plugs 200 and the remaining operational space for inserting and removing the plugs 200 are reduced, and the required installation area for the photovoltaic connector, i.e., the area occupied by the photovoltaic connector in the case 300, is reduced, and the entire case 300 is made smaller. Furthermore, by reducing the number of plugs 200, the installation of the photovoltaic connector is simplified and the installation efficiency is improved, and by reducing the number of plugs 200, the cost of the plugs 200 is reduced, and the overall cost of the photovoltaic connector is reduced.

[0035] Therefore, the solar power connector provided in the above embodiment reduces the area occupied by the case 300, makes the entire case 300 smaller, simplifies the installation of the solar power connector, improves the installation efficiency, and further reduces the overall cost of the solar power connector.

[0036] In the above photovoltaic power generation connector, when at least two plugs 200 are inserted into the outlet 100, the at least two plugs 200 may be arranged similarly and / or differently.

[0037] Here, the two plugs 200 being similar means that they have similar structures and sizes. The two plugs 200 being different means that the two plugs 200 may be arranged to have different structures and / or sizes. Specifically, when the two plugs 200 have different structures, the photovoltaic power generation cables 240 of the two plugs 200 may be arranged to have different structures.

[0038] Here, the fact that the photovoltaic power generation cables 240 of the two plugs 200 are different means that the number or polarity of the photovoltaic power generation cables 240 are different.

[0039] For ease of manufacturing and installation, when the outlet 100 is fitted with at least two plugs 200, the photovoltaic cables 240 of the at least two plugs 200 may be arranged similarly or differently.

[0040] In the above photovoltaic connector, in the plug 200 having at least two photovoltaic cables 240, the polarities of the at least two photovoltaic cables 240 may be arranged to be similar and / or different, which can be selected according to actual needs.

[0041] Specifically, if at least one plug 200 has at least two photovoltaic power cables 240, the at least two photovoltaic power cables 240 in at least one plug 200 are both positive photovoltaic power cables 240a, and / or the at least two photovoltaic power cables 240 are both negative photovoltaic power cables 240b, and / or at least one photovoltaic power cable 240 is a positive photovoltaic power cable 240a and at least one photovoltaic power cable 240 is a negative photovoltaic power cable 240b.

[0042] As shown in FIG. 19, eight plugs 200, namely, plug A200a, plug B200b, plug C200c, plug D200d, plug E200e, plug F200f, plug G200g, and plug H200h, are inserted into the outlet 100. Any two of the plugs 200 are the same, and each plug 200 has two photovoltaic power generation cables 240, namely, a positive photovoltaic power generation cable 240a and a negative photovoltaic power generation cable 240b. After the photovoltaic power generation connector of FIG. 19 is attached to the case 300, refer to FIG. 22. As can be seen by comparing FIG. 1 and FIG. 22, when the photovoltaic power generation cables 240 are the same, the required mounting area of ​​the photovoltaic power generation connector of FIG. 22 is small, that is, the area occupied by the photovoltaic power generation connector in the case 300 is small.

[0043] 20, four plugs 200, namely, plug A 200a, plug B 200b, plug C 200c, and plug D 200d, are inserted into the outlet 100. Any two of the plugs 200 are identical, and each plug 200 includes four photovoltaic power generation cables 240, namely, two positive photovoltaic power generation cables 240a and two negative photovoltaic power generation cables 240b.

[0044] As shown in Fig. 21, six plugs 200, namely, plug A200a, plug B200b, plug C200c, plug D200d, plug E200e, and plug F200f, are inserted into the outlet 100. The plug A200a has one positive photovoltaic power generation cable 240a, the plug B200b has one negative photovoltaic power generation cable 240b, the plug C200c and the plug D200d are similar and each has one positive photovoltaic power generation cable 240a and one negative photovoltaic power generation cable 240b, the plug E200e has six photovoltaic power generation cables 240 distributed as three positive photovoltaic power generation cables 240a and three negative photovoltaic power generation cables 240b, and the plug F200f has four photovoltaic power generation cables 240 distributed as two positive photovoltaic power generation cables 240a and two negative photovoltaic power generation cables 240b.

[0045] In the actual application process, the types and distribution of the plugs 200 are not limited to the three embodiments of FIGS. 19 to 21, and may be arranged in other ways.

[0046] In the above photovoltaic power generation connector, the specific structures of the plug 200 and the socket 100 can be selected according to actual needs.

[0047] Preferably, as shown in Figures 6 to 10, the plug 200 includes a plug housing 210 and a connection pin 230 provided in the plug housing 210, the plug housing 210 is inserted into the outlet 100, one end of the connection pin 230 is electrically connected and fixedly connected to the solar power generation cable 240, and the other end is electrically connected to the outlet 100, and the connection pin 230 is connected to the plug housing 210 in an insulated manner.

[0048] In the above structure, the arrangement of the connection pin 230 facilitates electrical connection between the solar power generation cable 240 and the outlet 100, and the arrangement of the plug housing 210 facilitates insertion of the plug 200 into the outlet 100.

[0049] To easily connect the photovoltaic cable 240 and the connection pin 230, the connection pin 230 may be crimped onto the photovoltaic cable 240, thereby achieving a fixed connection and an electrical connection at the same time through crimping.

[0050] In practical application, the solar power generation cable 240 and the connection pin 230 may realize the electrical connection and fixed connection in other ways, and are not limited to the above embodiment.

[0051] In the above photovoltaic power generation connector, in order to facilitate electrical connection between the connection pin 230 and the socket 100, the connection pin 230 is fitted and connected to the conductive part 120 of the socket 100 and is electrically connected thereto.

[0052] Specifically, the connection pin 230 may be externally fitted on the conductive part 120, or the conductive part 120 may be externally fitted on the connection pin 230. To improve stability, the connection pin 230 and the conductive part 120 may be engaged in a snap-fit ​​manner to achieve a fixed connection. For example, the connection pin 230 and the conductive part 120 may be intermediately fitted or tightly fitted, which is not limited in this embodiment.

[0053] In order to improve reliability, the photovoltaic power cable 240 and the plug housing 210 may be sealed. The sealed connection method may be selected according to actual needs, and is not limited in this embodiment.

[0054] In the above photovoltaic power generation connector, when the connection pin 230 is insulated and connected to the plug housing 210, the connection pin 230 may be directly insulated and connected to the plug housing 210, specifically, the plug housing 210 may be an insulating member. Of course, the connection pin 230 may be indirectly insulated and connected to the plug housing 210, specifically, the connection pin 230 is indirectly insulated and connected to the plug housing 210 by an insulating member.

[0055] In order to easily attach the connection pin 230, the plug 200 further includes a ferrule 220 fixed within the plug housing 210, the ferrule 220 having a mounting hole 222, and the connection pin 230 is positioned within the mounting hole 222 and engaged with the ferrule 220 so as to be positionally restricted along the axial direction of the connection pin 230.

[0056] In the above structure, the ferrule 220 connects the plug housing 210 and the connection pin 230. In this structure, the ferrule 220 may be an insulating member, thereby realizing an insulated connection between the connection pin 230 and the plug housing 210.

[0057] In the above plug 200, the entire connection pin 230 is located within the mounting hole 222 or protrudes from the mounting hole 222, which can be selected according to actual needs. For ease of installation, the entire connection pin 230 may be located within the mounting hole 222. In this case, when the connection pin 230 is connected to the conductive part 120 so as to be fitted and electrically connected, the conductive part 120 may enter the mounting hole 222 and be fitted within the connection pin 230. Specifically, the connection pin 230 is provided with an insertion hole 232, and the conductive part 120 enters into the insertion hole 232 of the connection pin 230.

[0058] 11 and 13, in order to facilitate the position restriction in the axial direction, one of the connecting pin 230 and the ferrule 220 is provided with a position limiting protrusion 223, and the other is provided with a position limiting groove 231 that engages with the position limiting protrusion 223. In order to facilitate mounting and improve stability, the position limiting protrusion 223 may be provided on the ferrule 220, and the position limiting groove 231 may be provided on the connecting pin 230.

[0059] The shape, number and size of the position limiting protrusion 223 and the position limiting groove 231 can be selected according to actual needs. In order to simplify the structure, the position limiting protrusion 223 and the position limiting groove 231 can be annular and arranged along the circumferential direction of the component in which they are located.

[0060] In order to facilitate installation and removal, the ferrule 220 is removably fixedly connected to the plug housing 210. Specifically, the ferrule 220 is locked to the plug housing 210, i.e., the ferrule 220 and the plug housing 210 are locked to realize a removably fixed connection.

[0061] 8 and 11 to 13, one of the ferrule 220 and the plug housing 210 is provided with a first buckle 221, and the other is provided with a first locking groove 212 that is locked with the first buckle 221. To facilitate attachment, the first buckle 221 may be provided on the ferrule 220, and the first locking groove 212 may be provided on the plug housing 210.

[0062] The structure, size and number of the first buckle 221 and the first locking groove 212 can be selected according to actual needs. In order to simplify the structure and ensure stability, the first buckle 221 and the first locking groove 212 may each be provided in two pieces, and each may be located at both ends of the corresponding member.

[0063] The plug 200 includes a plug housing 210, a ferrule 220, and a connection pin 230, and in order to improve safety, a photovoltaic power generation cable 240 is hermetically connected to the plug housing 210 and also to the ferrule 220. Preferably, the plug housing 210 and the ferrule 220 are both hermetically connected to the photovoltaic power generation cable 240 by a cable sealing member 250, and the plug housing 210 is provided with a locking hole 213 that is locked with the cable sealing member 250, and the cable sealing member 250 is located in the mounting hole 222. Here, the cable sealing member 250 is located between the plug housing 210 and the ferrule 220.

[0064] To facilitate installation, the mounting hole 222 has an end adjacent the locking hole 213 with a gradually expanding hole 2221 which engages with the cable sealing member 250, the gradually expanding hole 2221 gradually expanding from the end away from the locking hole 213 to the end adjacent the locking hole 213.

[0065] The method of installing the plug 200 is as follows. As shown in FIG. 11, the cable seal member 250 is attached to the locking hole 213 of the plug housing 210. The cable unit formed by the photovoltaic power generation cable 240 and the connecting pin 230 passes through the cable seal member 250. The position limiting groove 231 of the connecting pin 230 is locked by the position limiting protrusion 223 of the ferrule 220, thereby realizing the axial position limit. Under natural conditions, without external force or tools, neither the cable unit nor the ferrule 220 will loosen. As shown in FIG. 12, the cable 12, the ferrule 220 with the cable unit is pushed toward the cable sealing member 250, i.e., the ferrule 220 with the cable unit is pushed along the direction of the arrow in FIG. 12, and when a "click" sound is heard, the first buckle 221 of the ferrule 220 is fitted into the first locking groove 212 of the plug housing 210 and the cable sealing member 250 is tightened, see FIG. 8, in this way, the sealing between the photovoltaic cable 240 and the plug housing 210 is realized and the pull-out force of the photovoltaic cable 240 is increased.

[0066] In practical application, the installation process may first install the cable sealing member 250 in the installation hole 222 of the ferrule 220, specifically, first install the cable sealing member 250 in the gradually expanding hole 2221. Please refer to Fig. 13 for this. For other steps, please refer to the above, and no further description will be given here.

[0067] In the photovoltaic power generation connector, in order to facilitate attachment and removal of the plug 200, the plug 200 may be removably fixedly connected to the outlet 100 and removably electrically connected thereto.

[0068] To facilitate a removable fixed connection, the plug housing 210 is locked to the outlet 100. Specifically, one of the outlet 100 and the plug housing 210 is provided with a second locking groove 113, and the other is provided with a second buckle 211 that is locked and engaged with the second locking groove 113. For improved aesthetics and easier operation, the second buckle 211 may be provided on the plug housing 210, and the second locking groove 113 may be provided on the outlet 100.

[0069] The structure, size and number of the second buckle 211 and the second locking groove 113 can be selected according to actual needs. In order to simplify the structure and ensure stability, the second buckle 211 and the second locking groove 113 may be provided in two pieces, and may be located at both ends of the corresponding member.

[0070] In the above solar power generation connector, the solar power generation cable 240 is removably electrically connected to the outlet 100, thereby realizing the plug 200 to be removably electrically connected to the outlet 100. When the plug 200 includes a connecting pin 230 and a ferrule 220, the connecting pin 230 is removably electrically connected to the outlet 100.

[0071] As shown in Figures 3 and 4, the outlet 100 is provided with a slot 111 and a conductive part 120. As shown in Figures 14 and 15, a plug 200 is inserted into the slot 111, and a photovoltaic cable 240 is electrically connected to the conductive part 120.

[0072] In order for the plug 200 to be removably fixedly connected to the outlet 100 and removably electrically connected, the plug 200 is removably fixedly connected to the slot 111 and the photovoltaic power generating cable 240 is removably electrically connected to the conductive part 120.

[0073] When at least two plugs 200 are inserted into the socket 100, the slots 111 may correspond to the plugs 200 one by one to separate the different plugs 200. Of course, one slot 111 may correspond to at least two plugs 200, and is not limited to the above embodiment.

[0074] Here, when one plug 200 is inserted into the socket 100, the slots 111 may correspond to each plug 200. If there are at least two slots 111, the at least two slots 111 may be distributed sequentially along the length direction of the socket 100. In actual application, the at least two slots 111 may be distributed sequentially along the width direction of the socket 100, which is not a limitation of this embodiment.

[0075] In order to improve the adaptability of the outlet 100 to the plug 200, the photovoltaic power generation cables 240 and the conductive parts 120 correspond to each other. Of course, the conductive parts 120 may correspond to at least two photovoltaic power generation cables 240, which is not limited in this embodiment.

[0076] At least one plug 200 has at least two photovoltaic power generation cables 240, the slots 111 correspond to the plugs 200, and the photovoltaic power generation cables 240 correspond to the conductive parts 120, and at least two conductive parts 120 are provided in at least one slot 111, and a partition member 130 is provided in the slot 111 to separate the conductive parts 120 in the slot 111, and the partition member 130 separates two adjacent conductive parts 120 in the slot 111.

[0077] The number of the partition members 130 may be determined according to the number of the conductive parts 120, and the present embodiment is not limited thereto.

[0078] In the outlet 100, the conductive part 120 may be located completely within the slot 111 or may extend beyond the slot 111. To facilitate connection of the outlet 100 to a device within the case 300, one end of the conductive part 120 is located within the slot 111 and the other end extends beyond the bottom end of the slot 111.

[0079] To improve safety and reliability, the plug 200 is sealingly connected to the outlet 100. Preferably, the plug 200 is sealingly connected to the outlet 100 by a plug sealing member 140.

[0080] Meanwhile, the plug sealing member 140 may be provided on the bottom wall or side wall of the slot 111.
