[0002] With the development of building energy conservation and renewable energy application technologies, photovoltaic curtain walls, as a new type of building material integrating power generation and architectural decoration functions, have been widely used in the field of green building. Unitized photovoltaic curtain walls, due to their advantages such as convenient installation and structural stability, have become an important choice for the external envelope of high-rise buildings.

[0003] Traditional unitized photovoltaic curtain walls have the following shortcomings in practical applications: Low reliability of cable connections: In existing technologies, electrical connections between photovoltaic modules mostly use ordinary connectors for direct mating, lacking effective locking structures. During long-term use, factors such as building vibration and temperature changes can cause the connectors to loosen, leading to increased contact resistance, overheating, and even safety hazards.

[0004] Repair and replacement are difficult: When individual photovoltaic modules fail, a large area of ​​the curtain wall structure needs to be dismantled for repair or replacement, which is cumbersome, costly and affects the normal use of the building.

[0005] Therefore, it is necessary to provide a unitized photovoltaic curtain wall with a locking joint to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1 to 4 A unit photovoltaic curtain wall with a locking connector includes: two photovoltaic curtain wall bodies 1, adjacent sides of the two photovoltaic curtain wall bodies 1 are connected by an aluminum alloy buckle cover 2, the upper end of the aluminum alloy buckle cover 2 is fixedly connected to an aluminum alloy male column 3 and an aluminum alloy female column 4, the upper end of the aluminum alloy male column 3 and the aluminum alloy female column 4 is provided with an aluminum alloy junction box 5, a sleeve 12 is electrically connected to the photovoltaic curtain wall body 1 located on the left, the sleeve 12 extends into the aluminum alloy junction box 5 and is fixedly connected to a first connector 11, a cable 6 is provided in the aluminum alloy junction box 5, the front side of the cable 6 is provided with a second connector 14 connected to the first connector 11, the contact ends of the first connector 11 and the second connector 14 are both provided with a gold plating layer, the gold plating layer... The gold layer can reduce the contact resistance between the connectors. The rear side of the cable 6 extends to the outside. The first connector 11 and the second connector 14 are connected by a connecting assembly. The connecting assembly includes a fixing block 15 disposed on the outside of the first connector 11 and the second connector 14. Each of the fixing blocks 15 is provided with a through hole. A fixing pin 16 is slidably connected in every two mating through holes. Each fixing pin 16 is provided with a limiting groove on its outer wall. A limiting block 18 is slidably connected in each limiting groove. Each limiting block 18 is elastically connected to the inner bottom of the corresponding limiting groove by a spring 13. A retaining ring 17 is fixedly connected to the outer wall of each fixing pin 16. Each retaining ring 17 is located between two corresponding fixing blocks 15.

[0019] It should be noted that the connection design between the aluminum alloy cover 2 and the photovoltaic curtain wall body 1 not only achieves a stable splicing of adjacent curtain wall panels, but also provides an installation foundation for the aluminum alloy junction box 5 through the aluminum alloy male column 3 and aluminum alloy female column 4 fixed at its upper end. The aluminum alloy junction box 5, as the core component for electrical connection, has cables 6 inside that cooperate with the first connector 11 and the second connector 14 to complete the circuit series connection between the photovoltaic curtain wall and the outside world. The gold plating layer at the contact ends of the first connector 11 and the second connector 14 can significantly reduce the contact resistance between the connectors. In the connection assembly, the cooperation of the fixing pin 16 with the limiting block 18 and the spring 13 forms a reliable locking structure. The elastic force provided by the spring 13 causes the limiting block 18 to pop out, thereby connecting the two fixing blocks 15 together. The retaining ring 17 can prevent the tightness after connection and also prevent the fixing pin 16 from slipping off the fixing block 15 during replacement.

[0020] The aluminum alloy junction box 5 has a threaded hole on its rear side, and the outer wall of the cable 6 is fitted with a sealing head 7. The sealing head 7 is threadedly connected to the inner wall of the threaded hole, and multiple protrusions 8 are fixedly connected to the outer wall of the sealing head 7.

[0021] It should be noted that the multiple protrusions 8 on the outer wall of the sealing head 7 increase the friction with the operator's hand, making it easier to quickly tighten the sealing head 7 and improve installation efficiency.

[0022] In this configuration, sliding blocks 9 are fixedly connected to the inner walls of both sides of the aluminum alloy junction box 5. Triangular blocks are provided at the lower ends of the two sliding blocks 9. U-shaped plates 10 are fixedly connected to the upper ends of the aluminum alloy male column 3 and the aluminum alloy female column 4. Stop blocks are provided at the upper ends of the two U-shaped plates 10. Strip blocks are fixedly connected to the rear side of the U-shaped plates 10. The sliding blocks 9 are slidably connected to the inner walls of the U-shaped plates 10.

[0023] It should be noted that the sliding block 9 on the inner wall of the aluminum alloy junction box 5 is slidably connected to the U-shaped plate 10 on the aluminum alloy male column 3 and the aluminum alloy female column 4, which enables convenient installation and precise positioning of the aluminum alloy junction box 5.

[0024] The working principle of the unitized photovoltaic curtain wall with locking joint provided by this utility model is as follows: In the prefabrication stage, the aluminum alloy public column 3 is pre-drilled, the cable sleeve 12 and the internal first joint 11 are pre-installed, and are electrically connected with the photovoltaic glass module to form an independent unit module. During on-site assembly, two adjacent photovoltaic curtain wall bodies 1 are mechanically spliced ​​by aluminum alloy buckles 2 to construct the basic structure of the curtain wall.

[0025] In terms of electrical connection, the conductors of the photovoltaic glass module are connected to the first connector 11 inside the sleeve 12 during the assembly of the unit panel. Subsequently, the first connector 11 of the left panel is connected to the second connector 14 at the front end of the cable 6. To ensure a stable connection, the connecting components play a crucial role. The fixing pin 16 passes through the through hole of the fixing block 15 on the outside of the two connectors, and the limiting block 18 pops out under the elastic force of the spring 13, forming a mechanical lock; the retaining ring 17 effectively restricts the displacement of the fixing pin 16, ensuring long-term stable and reliable electrical connection.

[0026] In the sealing and protection process, the aluminum alloy junction box 5 has a threaded hole on the rear side, and the sealing head 7, which is fitted on the outer wall of the cable 6, is threadedly connected to it. After the first connector 11 and the second connector 14 are connected and the aluminum alloy junction box 5 is installed in place, the sealing head 7 is screwed into the threaded hole. Together with the waterproof strip at the connection between the aluminum alloy cover 2 and the photovoltaic curtain wall body 1, the double protection effectively isolates rainwater and prevents water vapor from entering and affecting electrical performance.

[0027] During later maintenance, if cable 6 is damaged, simply loosen the sealing head 7, then slide the aluminum alloy junction box 5 forward so that the first connector 11 and the second connector 14 are exposed to the outside through the threaded holes. By disconnecting the connection components of the first connector 11 and the second connector 14, cable 6 can be easily replaced.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
