Detailed Description

A junction box 100 according to an embodiment of the present utility model is described below with reference to fig. 1-4.

As shown in fig. 1 to 4, a junction box 100 according to an embodiment of the present utility model includes a box body 1, a diode 2, and a cable 3.

Specifically, the case 1 is formed with a housing groove 11. The diode 2 is disposed in the accommodating groove 11, and the diode 2 includes a body 21 and a plurality of pins 22, one end of each pin 22 is connected to the body 21, and the other end of each pin 22 extends out of the accommodating groove 11. The cable 3 extends into the receiving groove 11 and is electrically connected to one of the plurality of pins 22.

For example, in the example of fig. 1 to 4, the accommodating groove 11 extends in the longitudinal direction (for example, the X direction in fig. 1) of the case 1. The body 21 of the diode 2 is substantially cylindrical, and after the diode 2 is placed in the accommodating groove 11, the axial direction (for example, X direction in fig. 1) of the body 21 coincides with the longitudinal direction of the accommodating groove 11. One end of each pin 22 is connected to one axial end of the body 21, and the other end of each pin 22 is used for connection with a bus bar of a photovoltaic module. The cable 3 and the diode 2 are arranged along the length direction of the accommodating groove 11. One end of the cable 3 adjacent to the diode 2 is electrically connected to one of the plurality of pins 22 so that the diode 2 can be electrically energized to the outside through the cable 3. Thus, the electrical connection between the cable 3 and the pins 22 saves the original electrical conductors, thereby reducing the parts in the junction box 100, reducing the manufacturing process flow and lowering the production cost.

According to the junction box 100 of the embodiment of the present utility model, the electrical connection is made by connecting one of the pins 22 on the diode 2 with the cable 3. Therefore, compared with the traditional junction box, the junction box has the advantages that the parts in the junction box 100 are reduced, the manufacturing process flow of the junction box 100 is also reduced, and the production cost of the junction box 100 is further reduced.

According to some embodiments of the present utility model, the pin 22 has a bending structure 2203, one end of the bending structure 2203 is connected to the body 21, and one end of the bending structure 2203 protrudes out of the accommodating groove 11. As shown in fig. 2, the bending structure 2203 extends from one end of the body 21 towards a direction away from the body 21, and the bending structure 2203 extends out of the accommodating groove 11 to facilitate electrical connection with other components.

Further, the bending structure 2203 includes a first connecting section 221 and a second connecting section 222 connected to each other, wherein one end of the first connecting section 221 is connected to the body 21, and one end of the second connecting section 222 extends out of the accommodating groove 11. Referring to fig. 2, the first connection section 221 extends from one end of the body 21 in a direction away from the body 21, and the second connection section 222 extends from a free end of the first connection section 221 to the outside of the receiving groove 11. Specifically, the first connection section 221 extends in the length direction of the case 1, and the second connection section 222 extends in the height direction (for example, Y direction in fig. 1) of the case 1. Thus, the second connection section 222 can be electrically connected to other components.

According to some embodiments of the present utility model, at least one positioning hole 2211 is formed on one of the first connection section 221 and the bottom wall of the receiving groove 11, at least one positioning column 1111 is provided on the other one of the first connection section 221 and the bottom wall of the receiving groove 11, and the positioning column 1111 is fitted into the positioning hole 2211. When the positioning column 1111 is formed on the first connection section 221, the positioning hole 2211 is formed on the bottom wall of the receiving groove 11. When the positioning hole 2211 is formed on the first connection section 221, the positioning column 1111 is formed on the bottom wall of the receiving groove 11.

As shown in fig. 2, the first connecting section 221 is formed with a positioning hole 2211, and the bottom wall of the accommodating groove 11 is provided with a positioning column 1111, and the positioning column 1111 extends from the bottom wall of the accommodating groove 11 in the height direction of the box body 1. The positioning hole 2211 corresponds to the position of the positioning column 1111, so that the positioning hole 2211 can be engaged with the positioning column 1111 when the diode 2 is placed in the accommodating groove 11, thereby fixing the diode 2 in the accommodating groove 11 and preventing the diode 2 from falling off. Meanwhile, the positioning column 1111 can transfer the heat on the diode 2 to the bottom of the box 1, so as to radiate the diode 2, so that the diode 2 radiates more directly, and the radiating efficiency is improved.

Specifically, two positioning holes 2211 are formed on the first connection section 221, and the two positioning holes 2211 are arranged at intervals along the width direction (for example, the Z direction in fig. 4) of the first connection section 221. The accommodating groove 11 is provided with four positioning columns 1111, the four positioning columns 1111 are equally divided into two groups and are spaced apart along the length direction of the accommodating groove 11, and the two positioning columns 1111 positioned on the same side of the length direction of the accommodating groove 11 are arranged at intervals along the width direction of the accommodating groove 11. Therefore, the first connecting sections 221 at two ends of the body 21 can be fixed in the accommodating groove 11 through the positioning columns 1111, so that the installation firmness of the diode 2 is improved, the diode 2 can be prevented from shaking in the accommodating groove 11, and further, the electric connection between other components or cables 3 and the diode 2 is ensured.

By such arrangement, when the third connection section 223 is electrically connected with other components, the contact area between the other components and the third connection section 223 can be increased, which is beneficial to conduction, and meanwhile, the height of the junction box 100 can be reduced, and the interference between the pins 22 and other components can be avoided.

According to some embodiments of the utility model, the junction box 100 further comprises a press block 4, the press block 4 confining the cable 3 within the box body 1. For example, in the example of fig. 1, the press block 4 is provided above the cable 3, pressing the cable 3 into the accommodation groove 11 to prevent the cable 3 from falling out of the accommodation groove 11, thereby ensuring that the electrical connection between the cable 3 and the pins 22 of the diode 2 is maintained.

The press block 4 is located in the second sub-groove 112, and the press block 4 and the second sub-groove 112 together define the accommodation chamber 41, and another portion of the cable 3 is defined in the accommodation chamber 41. Referring to fig. 2, the first sub groove 111 and the second sub groove 112 are arranged along the length direction of the case 1. The cross-section of the first sub groove 111 is rectangular in shape. The second sub groove 112 is located at one end of the box body 1 in the length direction. The press block 4 is mounted in the second sub-groove 112, and a receiving cavity 41 is formed between the second sub-groove 112 and the press block 4, and the receiving cavity 41 can be matched with the cable 3. Thereby, the cable 3 can be fixed in the second sub-groove 112, and the cable 3 is prevented from falling out of the case 1.

Thereby, it is ensured that the press block 4 can be fixed on the case 1, not only preventing the press block 4 from falling, but also ensuring the firmness of the cable 3.
