DETAILED DESCRIPTION

[0049] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0051] In the description of the present application, it should be noted that the terms used, such as "top surface" and "bottom surface", refer to the top surface of the application applied to the electrical connector for multiple pairs of cable connection in the use state, and the bottom surface is the bottom surface; The terms used, such as "first" and "second", are only for differentiation, and do not indicate or imply that they have importance or sequential distinction; The terms used, such as "inner" and "outer", refer to the inner and outer of the specific profile. The use of the above terms is only for the convenience of clearly and simply expressing the technical scheme of the present application, and cannot be understood as a limitation of the present application.

[0052] In order for the relevant technical personnel to have a clearer and more accurate understanding of the technical scheme of the present application, the problems existing in the prior art will be further described in detail.

[0053] Firstly, in the application scene of building integrated photovoltaic, photovoltaic modules can be arranged on multiple facade of the building, and there are various relative positions between the setting positions. The existing electrical connector cannot meet the convenient arrangement requirement of wiring path.

[0054] For example, since the existing electrical connector can only connect one input cable and one output cable, when multiple photovoltaic modules are arranged in a ring shape on the roof structure (for example, multiple photovoltaic modules are arranged in a ring shape around the center of the circular roof), multiple electrical connectors are needed to be used to connect one by one. Thus, there is a problem of too many electrical connectors, which not only leads to a very complicated assembly process, but also has a high construction cost.

[0055] Secondly, when the photovoltaic module arranged on a facade is arranged at a certain angle with the grid-connected box, and there is a blockage of building structure (for example, roof water tank, advertising frame, exhaust duct, etc.) at this position, it is difficult to adjust the wiring path to be straight or to be bent at a large angle (for example, the grid-connected box is arranged at a certain position on the roof, the photovoltaic module is arranged on the side of the building, and the wiring path between them is arranged at a certain angle. Based on the requirement of building appearance, the wiring path cannot be arranged to be bent at a large angle. At the same time, based on the influence of the building structure on the roof part, such as roof water tank, advertising frame, exhaust duct, etc., the wiring path between them cannot be adjusted to be straight). At this time, the existing electrical connector will inevitably cause excessive bending of the cable when connected (for example, due to the blockage of the advertising frame, the cable needs to be bent by 90 degrees from the facade of the building and then connected through the electrical connector. The service life and safety of the cable at the bending part are not good). That is, the existing electrical connector cannot meet the wiring requirement of this application scene while ensuring the service life and safety of the cable.

[0056] In the prior art, for example, the wiring terminal provided in the Chinese patent document CN222508024U can meet the butt joint requirement of multiple input cables and one output cable, but its adaptability to different scenarios of photovoltaic module setting positions is low, and it is difficult to avoid the problems of excessive cable bending and insufficient cable length.

[0057] For example, when it is applied to multiple photovoltaic modules arranged in a ring shape, the cables of the multiple photovoltaic modules need to be bent at different angles to connect with the conductive sheets, and these cables not only may have the problem of excessive bending, but also, since the input platform is formed by bending the input section, it can be understood that the input platform is arranged in a linear manner, and the butt joint positions of the cables of different photovoltaic modules with the input platform are different, which may cause the problem of excessive or insufficient length of the cables of the photovoltaic modules, that is, it is difficult to adapt to multiple photovoltaic modules arranged in a ring shape.

[0058] Therefore, the present application provides a brand-new solution, that is, the electric connector for butt joint of multiple pairs of cables of the present application, and the technical concept of the present application is to provide a multipurpose electric connector to meet the butt joint requirement of photovoltaic modules with different external surfaces (that is, not only to meet the butt joint requirement of photovoltaic modules arranged at a certain angle with the grid-connected box, but also to meet the butt joint requirement of multiple photovoltaic modules arranged in a ring shape with the grid-connected box), and to reduce the number of electric connectors used, thereby reducing the assembly difficulty and construction cost.

[0059] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0060] As shown in Figures 1 to 10 The present application provides an electric connector 100 for butt joint of multiple pairs of cables, which comprises an insulating shell 1, a plurality of fixed conductors 2 and a butt joint assembly 3. The insulating shell 1 comprises a cover 12 and a box body 13 which are opposite to each other to enclose a containing cavity 11, the cover 12 is formed with an operation through hole 121, and the peripheral wall of the box body 13 is formed with a plurality of wire through holes 131 which are uniformly and spaced apart along the circumference of the box body 13, and the wire through holes 131 are used for the wire to access the containing cavity 11. The plurality of fixed conductors 2 are arranged in the containing cavity 11 and correspond to the plurality of wire through holes 131 one by one, and the fixed conductors 2 are used for butt joint with the accessed wires.

[0061] The docking assembly 3 is arranged in the accommodating cavity 11, and the docking assembly 3 comprises a first docking piece 31 and a second docking piece 32. The first docking piece 31 comprises a first conductor 311 and a first rotating column 312. One end of the first rotating column 312 is connected with the first conductor 311, and the other end of the first rotating column 312 extends out of the insulating shell 1 through the operation through hole 121. The first conductor 311 is configured to be in contact with or separated from a plurality of fixed conductors 2 at the same time when the first rotating column 312 rotates. The second docking piece 32 comprises a second conductor 321 and a second rotating column 322. The second rotating column 322 is sleeved outside the first rotating column 312. One end of the second rotating column 322 is connected with the second conductor 321, and the other end of the second rotating column 322 extends out of the insulating shell 1 through the operation through hole 121. The second conductor 321 is located above the first conductor 311, and the second conductor 321 is configured to be in contact with or separated from every adjacent two fixed conductors 2 at the same time along the circumference of the box body 13 when the second rotating column 322 rotates.

[0062] Through the above technical scheme, first, when facing the case that a plurality of photovoltaic assemblies are arranged in a ring shape, the first docking piece 31 of the present application can be used to form conductive contact with a plurality of fixed conductors 2 at the same time (as shown in FIG. 1), so that a plurality of fixed conductors 2 can be connected to a plurality of cables (one of the plurality of cables can be a cable connected to a grid-connected box, and the other cables can be output cables of photovoltaic assemblies) at the same time, so as to meet the cable convergence needs of a plurality of photovoltaic assemblies arranged in a ring shape, effectively reduce the number of arrangement of electrical connectors, and further effectively reduce the assembly difficulty and construction cost. Figure 4 Second, when facing the case that the grid-connected box and the photovoltaic assembly form a certain angle and there is an obstacle, it is difficult to adjust the connection line to be flat or to be bent at a large angle, the second docking piece 32 of the present application can be used to form conductive contact with two adjacent fixed conductors 2 at the same time, so that the two fixed conductors 2 arranged in this way not only can meet the cable docking needs of the photovoltaic assembly at a certain angle, but also can effectively ensure that the cables of the photovoltaic assemblies connected with the two fixed conductors 2 will not be excessively bent (for example, the electrical connector 100 of the present application applied to the docking of a plurality of pairs of cables can be arranged at the bending position, that is, the position where the original 90° bending is required to realize the docking, so that the bending angle of the cable will be greatly reduced), thereby ensuring the service life and safety.

[0063]

[0064] ​In the above-mentioned embodiments, it is to be noted that, first, the number of the fixed conductors 2 can be adjusted according to actual needs, and the present application does not make specific limitations thereon. Meanwhile, the setting angle and spacing of each adjacent two fixed conductors 2 can also be adjusted according to actual needs, and the present application does not make specific limitations thereon (however, it can be understood that, in order to improve the universality of the present application, the number of the fixed conductors 2 can be set to four, and the setting angle of each adjacent two fixed conductors 2, i.e. the access angle of the cable to be connected therewith, can be set to 90 degrees, so as to be suitable for most buildings).

[0065] Second, in the present application, the first connector 31 and the second connector 32 of the present application are selectively used to adapt to different settings of the photovoltaic module. In this way, not only can the connection requirements of the photovoltaic module in different settings be met, but also the universality of the present application can be effectively improved.

[0066] Third, the insulating shell 1 of the present application can be made of various insulating materials, such as rubber, plastic, etc., and the present application does not make specific limitations thereon. Meanwhile, the insulating shell 1 of the present application can also be equipped with corresponding mounting members, so as to be installed at any position of a building.

[0067] In one embodiment of the present application, as shown in Figures 3 to 5 the first conductor 311 of the present application can include a ring-shaped conductor 3111 and a plurality of first contact conductors 3112, the plurality of first contact conductors 3112 are arranged on the ring-shaped conductor 3111 in a circumferential direction of the ring-shaped conductor 3111, the plurality of first contact conductors 3112 are arranged one-to-one corresponding to the plurality of fixed conductors 2, and the spacing between each adjacent two fixed conductors 2 is greater than the size of the first contact conductor 3112, so that the first contact conductor 3112 can be kept in a non-contact state with the two fixed conductors 2 when it is moved between the two fixed conductors 2; the first rotating column 312 includes a first operating column body 3121 and a plurality of first connecting rod bodies 3122, the first connecting rod bodies 3122 are made of insulating material, and the two ends of the plurality of first connecting rod bodies 3122 are connected with the first operating column body 3121 and the ring-shaped conductor 3111, respectively.

[0068] In this way, the plurality of first contact conductors 3112 arranged in this way can be in one-to-one contact with the plurality of corresponding fixed conductors 2, and the plurality of first contact conductors 3112 can realize conduction through the ring-shaped conductor 3111 arranged thereon, so as to stably and reliably realize the conduction of the plurality of fixed conductors 2, and effectively adapt to the application scenario in which a plurality of photovoltaic modules are arranged in a ring shape.

[0069] In this embodiment, since the distance between each two adjacent fixed conductors 2 is greater than the size of the first contact conductor 3112, the first contact conductor 3112 can be moved between each two adjacent fixed conductors 2 to keep non-contact with the two fixed conductors 2, so that the connection relationship between the plurality of fixed conductors 2 can be effectively disconnected for installation, maintenance and replacement.

[0070] In addition, the plurality of first connecting rods 3122 can maintain the stability of the annular conductor 3111 and connect the first operating column 3121 and the annular conductor 3111, so that the annular conductor 3111 can be rotated under the driving of the first operating column 3121 to realize the switching between the on state and the off state.

[0071] It can be understood that in this embodiment, the number and angle of the first connecting rods 3122 can be selected and adjusted according to actual conditions, and the present application does not make specific limitations.

[0072] In an embodiment of the present application, as shown in Figure 6 and Figure 7 The second conductor 321 of the present application includes an arc-shaped conductor 3211 and two second contact conductors 3212, the two second contact conductors 3212 are respectively arranged at both ends of the arc-shaped conductor 3211, the two second contact conductors 3212 are arranged corresponding to each two adjacent fixed conductors 2, and the distance between each two adjacent fixed conductors 2 is greater than the size of the second contact conductor 3212, so that the second contact conductor 3212 can be moved between each two adjacent fixed conductors 2 to keep non-contact with the two fixed conductors 2; the second rotating column 322 includes a second operating column 3221 and a plurality of second connecting rods 3222, the second connecting rods 3222 are made of insulating material, and the two ends of the plurality of second connecting rods 3222 are respectively connected with the second operating column 3221 and the arc-shaped conductor 3211, and the second operating column 3221 is sleeved outside the first operating column 3121.

[0073] In this way, the two second contact conductors 3212 arranged in this way can be respectively in contact with each two adjacent fixed conductors 2, and the two second contact conductors 3212 can realize conduction through the arranged arc-shaped conductor 3211, so that the conduction of each two adjacent fixed conductors 2 can be stably and reliably realized, and the application scenario that the photovoltaic module and the grid-connected box are arranged at an angle and there is a blockage of the building structure to make it difficult to adjust the wiring path to be straight or to be bent at a large angle can be effectively adapted.

[0074] In this embodiment, since the spacing between each two adjacent fixed conductors 2 is greater than the size of the second contact conductor 3212, the second contact conductor 3212 can be moved between each two adjacent fixed conductors 2 to be in a non-contact state with the two fixed conductors 2, so that the communication relationship between each two adjacent fixed conductors 2 can be effectively disconnected for installation, maintenance and replacement.

[0075] In addition, the second connecting rod body 3222 can maintain the stability of the arc-shaped conductor 3211, and can connect the second operating column body 3221 and the arc-shaped conductor 3211, so that the arc-shaped conductor 3211 can be driven to rotate by the second operating column body 3221, thereby realizing the switching between the on state and the off state.

[0076] It can be understood that in this embodiment, the number and angle of the second connecting rod body 3222 can be selected and adjusted according to actual conditions, and the present application does not make specific limitations.

[0077] In an embodiment of the present application, as shown in Figure 3 , Figure 8 and Figure 9 , the docking assembly 3 of the present application can further include a third docking piece 33, the third docking piece 33 including a third conductor 331 and a third rotating column 332, one end of the third rotating column 332 being connected with the third conductor 331 and the other end extending out of the insulating shell 1 through the operating through hole 121, the third conductor 331 being arranged above the second conductor 321, and the third conductor 331 being configured to simultaneously contact or separate from the two fixed conductors 2 arranged oppositely when the third rotating column 332 rotates.

[0078] In this way, the third docking piece 33 thus arranged can effectively adapt to the problem of insufficient wiring distance when the photovoltaic assembly and the grid-connected box are arranged in the same line, and can replace the existing electrical connector.
