[0027] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.
[0028] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.
[0030] Example 1, reference Figures 1 to 5 , which is the first embodiment of the utility model, and this embodiment provides a connection structure, the installation component 100, includes a mounting shell 101, and one end of the mounting shell 101 is respectively provided with an input cable 102 and an output cable 103, wherein the arrangement of the input cable 102 and the output cable 103 facilitates the connection of the photovoltaic optimizer with the photovoltaic module junction box and the inverter or the next photovoltaic optimizer. The connection component 200 includes a connection port 201 arranged at one end of the input cable 102 or the output cable 103, and when connected, the installation connection of the photovoltaic module can be achieved by connecting the connection port 201 with the external connector. The fitting component 300 includes a fitting rack 301 arranged in the connection port 201.
[0031] Furthermore, the connection assembly 200 also includes a plurality of transmission rods 202 rotatably mounted on the connection port 201, and a transmission ball 203 is fixedly mounted on one end of the transmission rods 202, a transmission area is constructed between the transmission balls 203, and the diameter of the transmission area is smaller than the diameter of the connection port 201, and a covering sleeve 204 is provided on the external fixed sleeve of the connection port 201. And the covering sleeve 204 is made of elastic material. The protective layer of the external joint is generally the same size as the connection port 201, so during the insertion of the external joint, the external joint will contact the transmission ball 203 in the transmission area, and with the movement of the external joint, it will squeeze the transmission ball 203 to move outward, thereby expanding the middle size of the covering sleeve 204. Because the covering sleeve 204 is made of elastic material, the inlet of the covering sleeve 204 will shrink inward due to the influence of mechanical balance, making its contact with the external joint more fitting, such as Figure 6 shown.
[0032] Furthermore, an arc-shaped collar 205 is provided at one end of the covering sleeve 204 away from the connection port 201. The arc-shaped collar 205 makes the inlet end of the covering sleeve 204 tilted, thereby facilitating the insertion of the external connector into the covering sleeve 204, and improving the connection efficiency to a certain extent.
[0033] Furthermore, a heat sink 104 is provided outside the mounting housing 101. The heat sink 104 is made of metal. The photovoltaic optimizer generates a certain amount of heat during operation, especially when the electronic components inside it are running at high load. The heat sink 104 made of metal, as a heat conductor, can effectively conduct the heat generated by the components installed on the printed circuit board to the housing, and then dissipate it to the external environment through the housing, achieving a good heat dissipation effect.
[0034] During use, by stretching the wrapping sleeve 204, one end of the wrapping sleeve 204 fits more closely to the outer joint, effectively reducing the assembly gap between it and the outer joint, preventing the entry of impurities, improving the stability of the connection of the photovoltaic optimizer, and through the setting of the heat sink 104, the heat dissipation effect of the device is increased, and the service life of its internal components is extended.
[0035] Embodiment 2, referring to Figures 1 to 5 , which is the second embodiment of the present utility model. Different from the previous embodiment, the fitting assembly 300 further includes a fitting gear 303 coaxially fixed to the rotating end of the transmission rod 202, and the fitting gear 303 meshes with the fitting rack 301. A receiving groove is formed at one end of the connection port 201 away from the cable, and a fitting sleeve 302 fixedly connected to the fitting rack 301 is slidably installed in the receiving groove. During the movement of the transmission sphere 203 under force, the transmission rod 202 fixedly connected to it will also move synchronously, and then drive the fitting gear 303 coaxially fixed to its rotating end to rotate. When the fitting gear 303 rotates, it will drive the fitting rack 301 to move by means of tooth engagement. Since one end of the fitting rack 301 is fixedly connected to the fitting sleeve 302, one end of the fitting sleeve 302 will squeeze the protective layer outside the outer joint, further reducing the assembly gap therein, thereby achieving a tight fit with the outer joint, preventing the contamination of impurities such as rainwater and dust, and increasing the protection of the internal components of the connection port 201.
[0036] Furthermore, a guiding groove 305 is formed on the inner wall of the receiving groove, and a guiding block 304 fixedly connected to the fitting rack 301 is slidably installed in the guiding groove 305. When the fitting rack 301 moves, the guiding block 304 fixedly connected to the fitting rack 301 will move synchronously in the guiding groove 305. Through the cooperation between the guiding block 304 and the guiding groove 305, the movement stability of the fitting rack 301 is greatly improved.
[0037] Furthermore, the cross-sections of the guiding block 304 and the guiding groove 305 are arc-shaped. Compared with the traditional rectangular structure, the arc-shaped structure enables there to be more contact area between the guiding block 304 and the guiding groove 305, further increasing the movement stability of the fitting rack 301.
[0038] During use, through the cooperation between the fitting gear 303 and the fitting rack 301, the fitting sleeve 302 can be made to squeeze the outer joint, further reducing the assembly gap between it and the outer joint, achieving a tight fit with the outer joint, and preventing the contamination of impurities such as rainwater.
[0039] Embodiment 3, referring to Figure 6 and Figure 7, which is the third embodiment of the present utility model. This embodiment further provides a photovoltaic optimizer. It includes a sealing assembly 400, which includes a sealing ring 401 fixedly installed at one end of the fitting sleeve 302 away from the connection port 201. A sealing groove 402 is provided on the side of the sealing ring 401 away from the fitting sleeve 302. And the sealing ring 401 is made of rubber. During the connection process, the protective layer outside the outer joint will fit with the sealing groove 402. Since the sealing ring 401 is made of an elastic material, the outer joint can perfectly fit with the inner wall of the sealing groove 402.
[0040] Furthermore, the cross-section of the sealing groove 402 is trapezoidal, and its internal dimensions increase in sequence from inside to outside. The special setting of the cross-section of the sealing groove 402 facilitates the better embedding of the outer joint into the inner wall of the sealing groove 402, further improving the sealing performance of the connection between the connection port 201 and the outer joint.
[0041] During use, due to the special structure and material setting of the sealing groove 402, when the connection port 201 is connected to the outer joint, the protective layer outside the outer joint can be embedded into the inner wall of the sealing groove 402, thereby increasing the sealing performance of the connection between the connection port 201 and the outer joint and reducing the assembly gap between it and the outer joint.
