[0027] A kind of photovoltaic busbar capable of hiding an adapter according to an embodiment of the present utility model is as Figures 1-4 shown, and includes a bracket for parallel installation of a plurality of photovoltaic modules. The photovoltaic busbar 2 is installed in the bracket. On one side inside the photovoltaic busbar 2, there is a connection cavity 21 corresponding to the number of the plurality of photovoltaic modules. On the other side inside the photovoltaic busbar 2, there is an operation cavity, and the operation cavity is simultaneously communicated with the plurality of connection cavities 21. An operator 4 is provided in the operation cavity. A telescopic adapter 3 is provided in the connection cavity 21. The operator 4 drives the telescopic adapter 3 so that the connection end 31 of the telescopic adapter 3 can penetrate the side surface of the photovoltaic busbar 2. The connection end 31 is used for electrically connecting with the photovoltaic module. A transmission wire 26 is further provided inside the photovoltaic busbar 2, and the transmission wire 26 is respectively connected to the plurality of telescopic adapters 3 and transmits electric energy. Through the operation of the operator 4, when the telescopic adapter 3 needs to be connected to the connection head 62, the connection end 31 extends to the outside. After being connected, it retracts inside the photovoltaic busbar 2, effectively reducing the influence of external factors on the connection part, avoiding loosening or damage, and extending the service life of the product.

[0028] The photovoltaic module includes a photovoltaic main body 5, a junction box 6 is provided on the lower surface of the photovoltaic main body 5, a connecting wire 61 is fixedly provided on the junction box 6, and a connection head 62 matching the connection end 31 of the photovoltaic busbar 2 is provided at the end of the connecting wire 61. Specifically, the photovoltaic main body 5 includes a backplane 51, a first encapsulation film 52, a battery cell 53, a second encapsulation film 54 and a glass 55 stacked in sequence from bottom to top, and is fixed and formed by a pressure-bearing process. A fixing frame 56 for protecting the photovoltaic main body 5 is further provided outside the photovoltaic main body 5. Preferably, the battery cell 53 is composed of several small cells, and all the small cells are collected by a conductive busbar and then electrically connected to the junction box 6.

[0029] Specifically, the telescopic adapter 3 further includes a telescopic rod 32 and a force-bearing arc block 34. The two sides of the telescopic rod 32 are respectively connected to the connection end 31 and the force-bearing arc block 34. A fixing sleeve 22 matching the telescopic rod 32 is provided in the connection cavity 21. The telescopic rod 32 is nested in the fixing sleeve 22 and can extend and contract along the axial direction of the telescopic rod 32. A spring 33 is nested on the telescopic rod 32, and the front and back of the spring 33 are respectively limited by the fixing sleeve 22 and the force-bearing arc block 34. Specifically, the operation cavity is divided into a rotation cavity 24 and a pushing groove 23. The operator 4 includes a rotation screw 45 and a sliding block 42. The rotation screw 45 is placed in the rotation cavity 24 and can rotate in the rotation cavity 24. The sliding block 42 is nested in the rotation screw 45 through a threaded sleeve and is driven by the rotation screw 45 to slide in the pushing groove 23. The pushing groove 23 is communicated with the connection cavity 21. A pushing arc block 41 is provided at the front end of the sliding block 42. The pushing arc block 41 penetrates into the connection cavity 21 and pushes the force-bearing arc block 34 during the movement process to expose the connection end 31 to the outside of the photovoltaic busbar 2. Through the interaction of the curved arc structures of the pushing arc block 41 and the force-bearing arc block 34, the telescopic rod 32 is promoted to extend and contract, and the telescopic spring 33 can reset the telescopic rod 32 after the thrust slider leaves, so that the telescopic adapter 3 completes the telescopic process.

[0030] Preferably, a traction groove 25 is further opened in the operation cavity. The traction groove 25 is arranged opposite to the pushing groove 23 and penetrates through the photovoltaic busbar 2 to communicate with the outside. A traction block 43 is provided at a position on the sliding block 42 opposite to the pushing arc block 41. The traction block 43 extends to the upper surface of the photovoltaic busbar 2 through bending to form a guiding mark 44. A prompt mark 27 is provided at a position on the top surface of the photovoltaic busbar 2 corresponding to each of the plurality of connection cavities 21 one by one. The guiding mark 44 and the prompt mark 27 mainly play a prompting role to facilitate the actual operation of the operator.

[0031] Specifically, a knob 46 is sleeved on the front end of the photovoltaic busbar 2 through which the rotating screw 45 passes, facilitating the rotation of the rotating screw 45.

[0032] Preferably, a plurality of mounting plates 11 for mounting photovoltaic modules are provided on the bracket. The photovoltaic modules are placed on the bracket and locked with the mounting plates 11 through fastening bolts, ensuring that the photovoltaic modules are stably fixed on the bracket and not easily detached. At the same time, the mounting positions of the photovoltaic modules can be relatively determined, avoiding the problem that the connection between the connector 62 and the connection end 31 is too short to be connected after installation due to deviation.

[0033] During actual operation, after the installer installs the bracket, the photovoltaic busbar 2 is correspondingly installed into the bracket. Subsequently, the photovoltaic modules are placed on the bracket and fixed corresponding to the mounting plates 11. Then, by rotating the knob 46 to drive the rotating screw 45, the slider moves to drive the guiding marker 44 to move on the upper surface of the photovoltaic busbar 2. Through the prompt of the prompt marker 27, the connection end 31 of the telescopic adapter 3 protrudes to the outside of the photovoltaic busbar 2 and is exposed, so that the connector 62 of the photovoltaic module at the corresponding position can be connected to the connection end 31. After the connection is completed, continue to rotate the knob 46, and the connection end 31 will drive the connector 62 to retract and hide in the photovoltaic busbar 2. Then, the telescopic adapters 3 are connected in sequence to complete the overall docking process.

[0034] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
