[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a photovoltaic data collector, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the data collector includes a data collector processing end 1, a data collector fixed end 11 fixedly mounted on the data collector processing end 1, a female head protective shell 12 fixedly mounted on the end of the data collector fixed end 11 away from the data collector processing end 1, and an aviation connector female head 13 slidably mounted in the data collector fixed end 11 for plugging in the aviation connector male head 2. A driving mechanism 3 for driving the aviation connector female head 13 to slide is provided in the data collector processing end 1.

[0031] The driving mechanism 3 includes a connecting rod 31 that moves longitudinally on the data acquisition processing end 1, a first return spring 33 arranged in the data acquisition processing end 1 for pushing the connecting rod 31 to move away from the data acquisition processing end 1, a threaded rod 35 rotatably installed inside the data acquisition processing end 1 and screwed to the aviation connector female head 13, a gear 36 mounted on the threaded rod 35, and a rack 34 fixedly installed on the connecting rod 31 and meshing with the gear 36.

[0032] The male end 2 of the aviation connector is generally the data output end of equipment such as inverters, junction boxes, weather stations and electric meters. When the photovoltaic data collector is in use, the connecting rod 31 is pressed. When the connecting rod 31 moves downward, the rack 34 is driven to move downward. At the same time, the first reset spring 33 is compressed, which has a tendency to push the connecting rod 31 to move upward and reset in real time. At the same time, the rack 34 is driven to drive the gear 36 to rotate, thereby driving the threaded rod 35 to rotate. With the cooperation of the thread, the female end 13 of the aviation connector is moved along the threaded rod 35 toward the direction close to the female protective shell 12, and then the female end 13 of the aviation connector is extended from the female protective shell 12, so that the male end 2 of the aviation connector is convenient for being plugged into the female end 13 of the aviation connector.

[0033] When the female aviation connector 13 is not in use, the first return spring 33 presses the connecting rod 31, and the connecting rod 31 drives the female aviation connector 13 to retract into the data acquisition device processing end 1 through the rack 34 and the gear 36, so that the female aviation connector 13 is protected by the data acquisition device processing end 1 when not in use, is not easily bumped, and the service life of the female aviation connector 13 is extended.

[0034] Furthermore, in order to improve the efficiency of the first return spring 33 pushing the connecting rod 31, as shown in FIG. Figure 3 As shown, the driving mechanism 3 also includes a sliding plate 32 fixedly mounted on one end of the connecting rod 31 near the first return spring 33, and a limiting mechanism 4 for limiting the position of the male head 2 of the aviation connector is arranged inside the female head protective shell 12.

[0035] By setting the sliding plate 32, the contact area between the connecting rod 31 and the first reset spring 33 is increased, so that when the aviation connector male head 2 and the aviation connector female head 13 are separated, the first reset spring 33 pushes the connecting rod 31 to reset, thereby driving the aviation connector female head 13 to retract into the data acquisition device processing end 1.

[0036] Furthermore, in order to further stabilize the connection between the aviation connector male head 2 and the aviation connector female head 13, as Figure 4 and Figure 5 As shown, the limiting mechanism 4 includes a clamping block 41 slidably mounted on the male head 2 of the aviation connector and engaged with the female head protective shell 12, and a second reset spring 42 arranged inside the data acquisition processing end 1 for pushing the clamping block 41 to move away from the data acquisition processing end 1.

[0037] When the aviation connector male head 2 is plugged into the aviation connector female head 13, the clamping block 41 is pressed by the female head protective shell 12 and slides into the aviation connector male head 2. After the aviation connector male head 2 and the aviation connector female head 13 are plugged into each other, the clamping block 41 on the aviation connector male head 2 is clamped into the female head protective shell 12 under the action of the second return spring 42, so that the aviation connector male head 2 is clamped by the clamping block 41 after being plugged into the aviation connector female head 13, and is not easy to be separated from the female head protective shell 12.

[0038] Furthermore, in order to facilitate the operator to remove the aviation connector male head 2 from the female head protective shell 12, as shown in FIG. Figure 6 As shown, the limiting mechanism 4 further includes a pressing block 43 which is slidably mounted in the female head protection shell 12 and contacts the clamping block 41 .

[0039] When it is necessary to remove the male aviation connector 2 from the female protective shell 12, the operator presses the top pressure block 43 by hand, and the top pressure block 43 pushes the clamping block 41 to retract into the male aviation connector 2. At the same time, the operator pulls out the male aviation connector 2, and the female aviation connector 13 is reset under the action of the first reset spring 33 and retracted into the data acquisition device processing end 1.

[0040] In order to facilitate the clamping block 41 to be retracted into the aviation connector male connector 2 under the action of the female connector protective shell 12, as shown in FIG. Figure 4 and Figure 6 As shown, one end of the clamping block 41 close to the female head protective shell 12 has an inclined surface inclined toward the data collector fixed end 11.

[0041] When the aviation connector male head 2 is inserted into the female head protective shell 12 , the clamping block 41 can be easily retracted into the aviation connector male head 2 due to the action of the inclined surface.

[0042] It should be noted that in order to further stabilize the connection between the aviation connector male head 2 and the aviation connector female head 13, a plurality of limiting mechanisms 4 are provided, and the plurality of limiting mechanisms 4 are distributed in a circular array on the outer surface of the aviation connector male head 2. Through the provision of the plurality of limiting mechanisms 4, the aviation connector male head 2 is limited by the plurality of limiting mechanisms 4 after being inserted into the aviation connector female head 13, which is convenient for use.

[0043] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
