[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1-7 As shown in the figure, an embodiment of this utility model discloses a photovoltaic connector for a stable inverter connection, including a photovoltaic connector male 1 and a photovoltaic connector female 2. Trapezoidal connecting blocks 3 are fixed to both side walls of the photovoltaic connector female 2. A slot 4 is formed on the inner side wall of the top of each trapezoidal connecting block 3. A U-shaped housing 5 is fitted and fixed to the surface of the photovoltaic connector male 1. Two sliding plates 6 are symmetrically slidably installed inside the U-shaped housing 5. An elastic component 7 is installed on one side wall of each of the two sliding plates 6. The end of the elastic component 7 away from the sliding plate 6 is fixedly connected to the inner wall adjacent to the U-shaped housing 5. A trapezoidal locking block 8 adapted to the slot 4 is fixed to the other side wall of each of the two sliding plates 6. The inclined surface of the trapezoidal connecting block 3 is parallel to the inclined surface of the trapezoidal locking block 8. The trapezoidal locking block 8 slides through the U-shaped housing 5. On the adjacent sidewalls, one end of each of the two sliding plates 6 is fixed with an inclined plate 9. The surfaces of the two inclined plates 9 are fitted with trapezoidal pressure blocks 10. The inclined surfaces of the trapezoidal pressure blocks 10 are parallel to the surfaces of the corresponding inclined plates 9. A horizontal plate 11 is fixed to the surfaces of the two trapezoidal pressure blocks 10. The horizontal plate 11 is slidably installed inside the U-shaped box 5. Two T-shaped limiting blocks 14 are symmetrically fixed to the top of the horizontal plate 11. Two T-shaped limiting grooves 15 adapted to the T-shaped limiting blocks 14 are symmetrically opened on the inner wall of the top of the U-shaped box 5. This is to enable the horizontal plate 11 to move stably inside the U-shaped box 5 without falling off. A T-shaped handle 12 is fixed to the surface of the horizontal plate 11. A box cover 13 is hinged to the surface of the U-shaped box 5. A lock cylinder assembly 16 for locking with the U-shaped box 5 is installed at one end of the box cover 13.

[0026] When it is necessary to install the photovoltaic connector male 1 and the photovoltaic connector female 2 together, the photovoltaic connector female 2 can be aligned with the photovoltaic connector male 1 and inserted. During the insertion process, when the trapezoidal connecting block 3 contacts the corresponding trapezoidal locking block 8, the trapezoidal connecting block 3 continues to move upward and will press the trapezoidal locking block 8 into the U-shaped box 5. The trapezoidal locking block 8 will drive the corresponding sliding plate 6 to move towards the middle. The sliding plate 6 will squeeze the corresponding elastic component 7. When the photovoltaic connector female 2 and the photovoltaic connector male 1 are fully inserted together, the sliding plate 6 will move outward under the elastic force of the elastic component 7, so that the trapezoidal locking block 8 can be engaged in the slot 4 on the trapezoidal connecting block 3. Therefore, the photovoltaic connector female 2 and the photovoltaic connector male 1 can be fixedly connected together.

[0027] When it is necessary to separate the photovoltaic connector female head 2 and the photovoltaic connector male head 1 for maintenance, the disassembly process is as follows: use a key to open the lock cylinder assembly 16, then open the box cover 13, and then press the T-shaped handle 12 inward. The T-shaped handle 12 can drive the horizontal plate 11 to move inward, the horizontal plate 11 can drive the two trapezoidal pressure blocks 10 to move inward, the two trapezoidal pressure blocks 10 can press the two inclined plates 9 to move inward, the inclined plates 9 can drive the corresponding sliding plate 6 to move inward, at this time the elastic component 7 will be compressed, the sliding plate 6 can drive the corresponding trapezoidal locking block 8 to move inward, so that the trapezoidal locking block 8 can be disengaged from the slot 4 on the corresponding trapezoidal connecting block 3. In this way, the photovoltaic connector female head 2 and the photovoltaic connector male head 1 can be separated. The entire disassembly and assembly process does not require the use of special tools, saving maintenance costs and time. Finally, it should be noted that the lock cylinder assembly 16 is set on the box cover 13 to prevent unauthorized personnel from opening the box cover 13, thereby preventing unauthorized personnel from separating the photovoltaic connector female head 2 and the photovoltaic connector male head 1.

[0028] like Figure 4 and Figure 6 As shown, in some embodiments, the elastic component 7 includes two springs 701 and two telescopic sleeves 702. The two ends of the two springs 701 are fixedly connected to one side wall of the slide plate 6 and the adjacent inner side wall of the U-shaped box 5, respectively. The two telescopic sleeves 702 are respectively disposed inside the two springs 701. The two ends of the two telescopic sleeves 702 are fixedly connected to one side wall of the slide plate 6 and the adjacent inner side wall of the U-shaped box 5, respectively. By setting the springs 701 and the telescopic sleeves 702, when the slide plate 6 is subjected to inward pressure, the slide plate 6 can move inward stably. When the slide plate 6 is not subjected to pressure, under the elastic force of the springs 701, the slide plate 6 will move outward stably.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
