Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to a photovoltaic connector structure. Background Art

[0002] Photovoltaic power generation system, referred to as photovoltaic, refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic connectors are various connecting devices within the photovoltaic power generation system.

[0003] Most existing photovoltaic connectors are male-female plug-in structures. After the male and female connectors are plugged in, the male buckle and the female bayonet are used to assemble and connect. However, this plug-in method has certain shortcomings. When there is shaking during operation, the plugged connector is easy to loosen, and the electrical performance cannot be guaranteed to be stable. Therefore, there is an urgent need for a connector that is firmly plugged in and semi-permanent to improve the connection strength. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic connector structure to solve the problems existing in the background technology.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A photovoltaic connector structure comprises a male end and a female end, the male end comprises an inner cavity, installation cavities are arranged on both sides of the end of the male end, the installation cavity comprises a vertical cavity and a horizontal cavity, a limiting assembly is arranged in the vertical cavity, and a clamping assembly is arranged at the end of the female end, the limiting assembly comprises an upper wedge-shaped slider, a spring and a lower wedge-shaped slider, one end of the vertical cavity is communicated with the inner cavity, the other end of the vertical cavity is communicated with the horizontal cavity, one end of the horizontal cavity is communicated with the outside, one end of the lower wedge-shaped slider is located in the vertical cavity, one end of the inclined surface of the lower wedge-shaped slider extends into the inner cavity, a baffle is arranged at the lower end opening of the vertical cavity, one end of the upper wedge-shaped slider is located in the inner cavity, and the other end of the upper wedge-shaped slider extends into the horizontal cavity;

[0007] The clamping assembly includes an upper wedge-shaped fixing block and a round table. The inclined surface of the round table matches the inclined surface of the lower wedge-shaped slider. The lower wedge-shaped slider is slidably connected to the installation cavity through the round table. The diameter of the large end of the round table is adapted to the inner diameter of the inner cavity. The positions of the two upper wedge-shaped fixing blocks correspond to the openings of the two transverse cavities respectively. The inclined surface of the upper wedge-shaped fixing block matches the inclined surface of the upper wedge-shaped slider. The upper wedge-shaped slider is slidably connected to the installation cavity through the upper wedge-shaped fixing block. The male end is clamped and fixed to the female end through the clamping assembly and the limiting assembly.

[0008] Furthermore, the spring is located between the upper wedge-shaped slider and the lower wedge-shaped slider, one end of the spring is fixed to the upper wedge-shaped slider, and the other end of the spring is fixed to the lower wedge-shaped slider.

[0009] Furthermore, the outer dimensions of the upper wedge-shaped fixing block are matched with the inner dimensions of the transverse cavity.

[0010] Furthermore, the truncated cone is located on one side of the end of the female end, and the upper wedge-shaped fixing block is located on the side of the end of the truncated cone away from the female end. An abutment groove is provided between the truncated cone and the upper wedge-shaped fixing block, and the groove width of the abutment groove is adapted to the width of the lower wedge-shaped slider, and the groove depth of the abutment groove is adapted to the maximum extension dimension of the lower wedge-shaped slider.

[0011] Furthermore, a rubber ring is provided on the round platform.

[0014] 2) The structure is simple and easy to operate. Through one plug-in action, the male end and the female end can be plugged in, fixed and locked to form a semi-permanent plug-in structure. The upper wedge-shaped fixing block completely presses the upper wedge-shaped slider into the vertical cavity. At the same time, the upper wedge-shaped slider drives the spring to compress the lower wedge-shaped slider, so that the lower wedge-shaped slider is pressed against the abutment groove to complete the locking.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0024] like Figure 1-Figure 6 As shown, a photovoltaic connector structure includes a male end 1 and a female end 2, the male end 1 includes an inner cavity 101, and mounting cavities are provided on both sides of the end of the male end 1, and the mounting cavity includes a vertical cavity 302 and a horizontal cavity 301. A limiting component is provided in the vertical cavity 302, and a clamping component is provided at the end of the female end 2. The limiting component includes an upper wedge-shaped slider 303, a spring 305 and a lower wedge-shaped slider 304. One end of the vertical cavity 302 is connected to the inner cavity 101. , the other end of the vertical cavity 302 is connected to the horizontal cavity 301, one end of the horizontal cavity 301 is connected to the outside, one end of the lower wedge-shaped slider 304 is located in the vertical cavity 302, one end of the inclined surface of the lower wedge-shaped slider 304 extends into the inner cavity 101, a baffle 306 is provided at the lower end opening of the vertical cavity 302, one end of the upper wedge-shaped slider 303 is located in the inner cavity 101, and the other end of the upper wedge-shaped slider 303 extends into the horizontal cavity 301;

[0025] The clamping assembly includes an upper wedge-shaped fixing block 402 and a round table 401. The inclined surface of the round table 401 cooperates with the inclined surface of the lower wedge-shaped slider 304. The lower wedge-shaped slider 304 is slidably connected to the installation cavity through the round table 401. The diameter of the large end of the round table 401 is adapted to the inner diameter of the inner cavity 101. The positions of the two upper wedge-shaped fixing blocks 402 correspond to the openings of the two transverse cavities 301 respectively. The inclined surface of the upper wedge-shaped fixing block 402 cooperates with the inclined surface of the upper wedge-shaped slider 303. The upper wedge-shaped slider 303 is slidably connected to the installation cavity through the upper wedge-shaped fixing block 402. The male end 1 is clamped and fixed to the female end 2 through the clamping assembly and the limiting assembly.

[0026] Through the above technical solution, when the female end 2 is inserted into the male end 1, the table 401 first contacts the upper wedge-shaped slider 303, and through the action of the inclined surface, the upper wedge-shaped slider 303 is pressed into the vertical cavity 302. At this time, the spring 305 drives the upper wedge-shaped slider 303 to press against the inner wall of the horizontal cavity 301, and the table 401 enters the inner cavity 101; as the inclined surface cooperation between the table 401 and the upper wedge-shaped slider 303 disappears, the upper wedge-shaped slider falls under the action of its own weight and the spring 305, and the table 401 cannot escape from the inner cavity 101.

[0027] When the round table 401 enters the inner cavity 101, the upper wedge-shaped fixing block 402 is inserted into the horizontal cavity 301 at the same time, and the inclined surface of the upper wedge-shaped fixing block 402 cooperates with the inclined surface of the upper wedge-shaped slider 303, so that the upper wedge-shaped slider 303 is pressed into the vertical cavity 302. Until the round table 401 is away from the lower wedge-shaped slider 304, the upper wedge-shaped fixing block 402 completely presses the upper wedge-shaped slider 303 into the vertical cavity 302, and at the same time, the upper wedge-shaped slider 303 drives the spring 305 to squeeze the lower wedge-shaped slider 304, so that the lower wedge-shaped slider 304 is pressed against the abutment groove 403, and the locking is completed.

[0028] The male end 1 and the female end 2 can be effectively connected by the above-mentioned limiting assembly and the clamping assembly, and the plugging and locking are completed in one plugging process, thereby improving the firmness of the plugging.

[0029] like Figure 3 and Figure 4 As shown, when the male end 1 is not plugged into the female end 2, under the action of the spring 305, the lower wedge-shaped slider 304 extends into the inner cavity 101, and under the action of the baffle 306, the lower wedge-shaped slider 304 will not fall out completely, and the upper wedge-shaped slider 303 presses against the inner wall of the transverse cavity 301 under the elastic force of the spring 305.

[0030] like Figure 5 and Figure 6 As shown, the truncated cone 401 surrounds the female end 2. After being inserted into the inner cavity 101, the sealing effect can be improved because the large end diameter of the truncated cone 401 is adapted to the inner diameter of the inner cavity 101. At the same time, a circle of rubber ring 404 is provided on the truncated cone 401 to further improve the sealing and waterproof effect. Two upper wedge-shaped fixing blocks 402 are located on both sides of the female end 2 corresponding to the position of the transverse cavity 301. The upper wedge-shaped fixing blocks 402 can also play a guiding and positioning role during insertion.

[0031] like Figure 1 and Figure 2 As shown, after the male end 1 and the female end 2 are fully plugged in, the cone 401 and the rubber ring 404 are fully inserted into the inner cavity 101, and the lowest point of the lower wedge-shaped slider 304 abuts against the abutment groove 403. At this time, the upper wedge-shaped slider 303 is also fully inserted into the horizontal cavity 301 to complete the fixation.

[0032] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
