[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: a fuse connector, including a fuse body 1 and a mounting member 11. Two groups of fuse bodies 1 are provided and respectively installed in connection unit one and connection unit two. One ends of connection unit one and connection unit two are provided with a mounting member 11, and the mounting member 11 is provided with:

[0028] A connection component that electrically connects connection unit one and connection unit two to the mounting member 11;

[0029] An adjustment component that can adjust the conversion between two connection modes of the two groups of fuse bodies 1 in parallel and series.

[0030] A female mating type terminal 9 is provided on connection unit one, and a male mating type terminal 10 is provided on connection unit two. The female mating type terminal 9 and the male mating type terminal 10 can be mated and interconnected with the photovoltaic system circuit.

[0031] During operation, in the present invention, two groups of fuse bodies are inserted into the mounting member through connection unit one and connection unit two, such that the mounting member is interconnected with the fuse bodies within connection unit one and connection unit two respectively. The adjustment assembly is provided with two modes: parallel and series. In the series mode, there are two ways: one is that two groups of fuse bodies are in series, and the other is that only the fuse body within connection unit two is connected. When only connection unit two is connected, current is input into the fuse body of connection unit two through the sub-pair plug terminals, and then output from the female pair plug terminals through the mounting member. At this time, the fusing current of the fuse within connection unit two is the fusing current of the circuit. When two groups of fuse bodies are in series, the circuit is input into connection unit two through the sub-pair plug terminals, then enters the fuse body of connection unit one through the mounting member, and finally outputs from the female pair plug terminals. At this time, the fusing current of the fuse body with a lower fusing current within connection unit one is used as the fusing current of this circuit, thereby realizing the adjustment of the fusing current of the circuit. Additionally, in the parallel mode, current is input into connection unit two through the sub-pair plug terminals, flows through the fuse body within it, and then enters the mounting member. In the mounting member, the circuit is shunted, part of it is directly output through the female pair plug terminals, and part of it enters connection unit one, flows through the fuse body within it, and then is output from the female pair plug terminals. In this way, when the circuit current increases, the group of fuse bodies with a lower fusing current fuses first. The fused fuse can be used as a warning. While warning the user that the circuit current is abnormal, the group of fuse bodies with a larger fusing current ensures that the circuit operation will not suddenly interrupt, facilitating manual data retention before maintenance.

[0032] As a further solution of the present invention, the connection assembly includes an output line 16, an input line 15, and a side connection line 14. Connection seats 24 are fixedly installed on both the output line 16 and the input line 15. Two groups of insertion slots 13 are symmetrically arranged at the lower end of the mounting member 11. Inner connecting rods 12 are fixedly installed above the insertion slots 13 on the mounting member 11. One end of the output line 16 away from the connection seat 24 is fixedly connected to the inner connecting rod 12. One end of the input line 15 is fixedly connected to the inner connecting rod 12. One end of the side connection line 14 away from the connection seat 24 is fixedly installed with an upper connecting rod 19.

[0033] During operation, in the present invention, the output line 16 is connected to the fuse body 1 within connection unit one, the side connection line 14 is directly interconnected with the female pair plug terminals 9 on connection unit one, and the input line 15 is connected to the fuse body 1 within connection unit two. When making connection adjustments, the connection method of the input line 15, the output line 16, and the side connection member 14 is changed to complete the adjustment of the connection method of the fuse bodies 1 within connection unit one and connection unit two.

[0034] As a further solution of the present invention, the adjusting component includes an installation groove 20 which is opened on the installation member 11 and is located between the output line 16 and the input line 15. A rotating disk 21 is rotatably installed at the middle position of the installation groove 20. A connecting ball 23 is fixedly installed on one side of the rotating disk 21.

The positioning connecting member 22 can be attached to the edge of the rotating disk 21. The connecting ball 23 is matched with the connecting seat 24 and can be embedded into the connecting seat 24.

[0035] During operation, three groups of connecting balls 23 are arranged on the rotating disk 21 in the present invention. When the connecting ball 23 is only clamped into the connecting seat 24 of the output line 16, the input line 15 is interconnected with the output line 16 through the positioning connecting member 22 and the rotating disk 21. At this time, the fuse bodies 1 in the first connecting unit and the second connecting unit are connected in series to the circuit. When the rotating disk 21 rotates so that the connecting ball 23 is only connected to the connecting seat 24 of the side connecting line 14, only the fuse body 1 in the second connecting unit is connected to the circuit at this time. When the rotating disk 21 rotates so that the connecting balls 23 are clamped on the connecting seats 24 of both the output line 16 and the side connecting line 14, the fuse bodies 1 in the first connecting unit and the second connecting unit are connected in parallel to the circuit at this time.

[0036] As a further solution of the present invention, the first connecting unit includes a first upper connecting member 3 and a first lower connecting member 2. The fuse body 1 is clamped between the first upper connecting member 3 and the first lower connecting member 2. A threaded member 301 is arranged at the lower end of the first upper connecting member 3. A connecting nut 6 is fixedly installed at the upper end of the first lower connecting member 2. The connecting nut 6 cooperates with the threaded member 301. A limiting ring 7 is arranged at the connection between the connecting nut 6 and the threaded member 301.

The lower connecting rod 25 can be inserted into the lower lower communication groove 18 and can interconnect the lower connecting line 17 and the female plug-in type terminal 9.

[0041] During operation, the upper ends of the fuse bodies 1 in the present invention are interconnected with the upper insertion rods 8. After the upper insertion rods 8 are inserted into the insertion slots 13, they are connected to the inner connecting rods 12, so that the output line 16 and the input line 15 are interconnected respectively.
