Description

Technical Field

[0001] The utility model relates to the field of photovoltaics, in particular to a photovoltaic interface device. Background Art

[0002] With the continuous upgrading of photovoltaic technology, existing photovoltaic facilities are becoming more and more perfect, and the application scenarios of photovoltaics are becoming more and more extensive. However, there are still some problems in the installation and replacement of photovoltaic facilities, such as the convenience and stability of connection cannot be guaranteed. The convenience of existing connection facilities such as the MC4 interface is poor, which makes the disassembly process very complicated. This is mainly because there are outward-protruding buckles and rubber pads on the MC4 interface. Once the buckle is inserted into the inside of the link female head, it is not easy to remove the buckle from the inside of the link female head. By forcibly pulling the link male head and the link female head, the buckle can easily break, making the MC4 interface scrapped. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In one embodiment, please refer to the appendix of the specification. Figure 1-4As shown, a photovoltaic interface device described in the present invention includes a link male connector 1, a link female connector 4 plugged into the link male connector 1 is provided below the link male connector 1, a plug-in component 2 is provided on the link male connector 1, and the plug-in component 2 is used to connect the link male connector 1 and the link female connector 4, and a locking component 3 is provided on the link female connector 4, and the locking component 3 is used to lock the plug-in component 2; the plug-in component 2 enters the interior of the locking component 3 and rotates to lock it.

[0020] The provided link male head 1 and link female head 4 can be installed together, which is convenient for the installation and disassembly of the photovoltaic cable. In order to prevent the installed link male head 1 and link female head 4 from falling off by themselves, the provided plug-in component 2 and locking component 3 are coordinated so that the plug-in component 2 inserted into the locking component 3 will not be separated from the inside of the locking component 3, and only when a certain force drives the plug-in component 2 to separate from the inside of the locking component 3 can the plug-in component 2 and the locking component 3 be separated, thereby realizing the separation of the link male head 1 and the link female head 4.

[0021] The link male connector 1 is provided with an insert rod 11 , and the link female connector 4 is provided with a socket 41 , and the insert rod 11 enters the socket 41 for internal connection.

[0022] The plug assembly 2 includes a locking rod 21 provided on the link male connector 1 , a locking block 22 protruding laterally outward is provided at the end of the locking rod 21 , and an extrusion portion 23 is provided at the connection between the locking rod 21 and the locking block 22 .

[0023] Locking is achieved by the provided locking block 22 entering the interior of the locking assembly 3; the locking portion will continuously squeeze the locking assembly 3 during the process of entering the interior of the locking assembly 3, causing the locking assembly 3 to move, and the locking assembly 3 will always conflict with the locking portion.

[0024] The locking assembly 3 includes a rod groove 31 formed on the link female connector 4 , a locking groove 32 is provided at the bottom of the rod groove 31 , an inner groove 35 is provided inside the link female connector 4 , and an end of the locking groove 32 is connected to the inner groove 35 .

[0025] The locking rod 21 is extended from the position of the rod groove 31 so that the locking block 22 enters the interior of the locking groove 32. The locking rod 21 is rotated, and the locking block 22 rotates synchronously with the locking rod 21. When the locking block 22 enters the interior of the locking groove 32, the locking block 22 is limited in the longitudinal direction, so that the locking block 22 cannot move, thereby achieving the effect of locking the locking block 22 and the locking groove 32 with each other.

[0026] The locking assembly 3 also includes an elastic member 34 arranged inside the inner groove 35 , and an extrusion block 33 is arranged inside the inner groove 35 . One end of the extrusion block 33 is connected to the elastic member 34 , and the elastic member 34 pushes the extrusion block 33 to slide inside the inner groove 35 .

[0027] In order to prevent the locking block 22 from loosening horizontally inside the locking groove 32 after being locked, the elastic member 34 is provided to push the extrusion block 33, and the extrusion block 33 will always be in conflict with the extrusion portion 23; when the elastic member 34 pushes the extrusion block 33 to move, the extrusion block 33 is squeezed on the locking portion, so that the locking block 22 and the locking groove 32 are locked with each other and are not easy to separate.

[0028] The extrusion portion 23 is an arc-shaped structure; one end of the extrusion block 33 is set as an arc-shaped surface, and the extrusion portion 23 is in contact with the extrusion block 33. When the extrusion portion 23 moves downward as the locking rod 21 moves on the extrusion block 33, the extrusion block 33 moves toward the inside of the inner groove 35 to compress the elastic member 34.

[0029] When the locking block 22 enters the notch of the locking groove 32, the elastic member 34 pushes the locking block 22 into the interior of the locking groove 32 to achieve locking. At this time, the elastic member 34 is in a natural telescopic state. When the locking block 22 needs to be removed from the interior of the locking groove 32, the locking rod 21 needs to exert an effect to overcome the elastic force of the elastic member 34 in order to remove the locking block 22 from the interior of the locking groove 32, so as to facilitate the stability of the link male head 1 and the link female head 4 after installation, and will not damage the structure of the link male head 1 and the link female head 4 during disassembly.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
