Description

Technical Field

[0001] This utility model belongs to the field of junction boxes, specifically, it relates to a junction box for photovoltaic modules. Background Technology

[0002] A photovoltaic junction box is a connecting device between a solar cell array composed of solar cell modules and a solar charging control device. Its main function is to connect and protect the solar photovoltaic modules, connect the power generated by the solar cells to external lines, and conduct the current generated by the photovoltaic modules.

[0003] A photovoltaic module junction box mainly consists of three parts: the box body, cables, and connectors. The connectors are located inside the box body, and the cables are connected to the connectors through the connectors. When the connectors are connected to the connectors, the connecting wires of the connectors are easily pulled, which affects the stability of the wiring. Severe pulling may also cause the connectors to loosen. Moreover, the connectors are generally different in size, and it is not easy to prevent different connectors from loosening.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a photovoltaic module junction box, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A photovoltaic module junction box includes: a junction box body and multiple plugs, a photovoltaic line is connected to one side of the junction box body, multiple interfaces are provided on one side of the junction box body, and a fixing box is provided on one side of the junction box body;

[0008] The plurality of plugs correspond to the plurality of interfaces, and each of the plurality of plugs is connected to a wire;

[0009] The fixing box contains multiple elastic anti-loosening components corresponding to the multiple plugs, and the fixing box contains adjustment components that correspond one-to-one with the multiple elastic anti-loosening components.

[0010] Optionally, the elastic anti-loosening component includes a movable box slidably connected to one side of the fixed box and an anti-loosening block slidably connected to the inside of the movable box. The anti-loosening block has a pressing surface on the side opposite to the plug, and a spring is fixedly connected between the anti-loosening block and the movable box. The pressing surface is an arc surface or an inclined surface.

[0011] Optionally, the anti-loosening block is provided with a wire groove.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] The elastic anti-loosening component installed inside the fixing box automatically locks the plug in place when it is inserted into the interface, reducing the possibility of the plug and interface becoming loose. The adjusting component installed on the two fixing boxes can adjust the position of the elastic anti-loosening component to accommodate the size of the plug, making it easy to prevent loosening of plugs of different sizes, thereby improving the stability of the plug and interface connection.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides a photovoltaic module junction box, including: a junction box body 1 and multiple plugs 4, a photovoltaic line 2 is connected to one side of the junction box body 1, multiple interfaces 3 are provided on one side of the junction box body 1, and a fixing box 6 is provided on one side of the junction box body 1.

[0028] Multiple plugs 4 correspond to multiple interfaces 3, and each of the multiple plugs 4 is connected to a wire 5;

[0029] The fixing box 6 is provided with multiple elastic anti-loosening components 8 corresponding to multiple plugs 4, and the fixing box 6 is provided with adjustment components 9 corresponding to each of the multiple elastic anti-loosening components 8.

[0030] The elastic anti-loosening component 8 installed inside the fixing box 6 can automatically lock the plug 4 into the interface 3 when the plug 4 is inserted into the interface 3, reducing the possibility of the plug 4 and the interface 3 becoming loose. The adjusting component 9 installed on the two fixing boxes 6 can adjust the position of the elastic anti-loosening component 8 to adapt to the size of the plug 4, making it easy to prevent the plug 4 of different sizes from becoming loose, thereby improving the stability of the connection between the plug 4 and the interface 3.

[0031] like Figure 4 As shown, the elastic anti-loosening component 8 in this embodiment includes a movable box 801 slidably connected to one side of the fixed box 6 and an anti-loosening block 802 slidably connected to the inside of the movable box 801. The anti-loosening block 802 has a pressing surface 803 on the side opposite to the plug 4. A spring 11 is fixedly connected between the anti-loosening block 802 and the movable box 801. The pressing surface 803 is an arc surface or a slope surface.

[0032] The anti-loosening block 802 has a wire groove 12. When the anti-loosening block 802 is engaged with the plug 4, the wire 5 is located in the wire groove 12, which reduces the squeezing of the wire 5 by the anti-loosening block 802.

[0033] By using the pressing surface 803 provided on the anti-loosening block 802, when the plug 4 is inserted into the interface 3, the plug 4 causes the anti-loosening block 802 to enter the movable box 801 by pressing the arc surface or the inclined surface. When the plug 4 is fully connected to the interface 3, the anti-loosening block 802 is ejected from the movable box 801 by the elastic force of the spring 11 to lock the plug 4 in place and prevent it from loosening.

[0034] like Figure 4As shown, the adjustment component 9 in this embodiment includes a threaded rod 901 rotatably connected to the inside of the fixed box 6, a knob 902 fixedly connected to the end of the threaded rod 901 that passes through the fixed box 6, and a movable box 801 threadedly connected to the threaded rod 901. There is friction between the knob 902 and the fixed box 6, which reduces the possibility of the knob 902 becoming loose.

[0035] When it is necessary to adjust the position of the anti-loosening block 802, turn the knob 902. The rotation of the knob 902 drives the threaded rod 901 to rotate. The rotation of the threaded rod 901 drives the movable box 801 to move within the fixed box 6. The movement of the movable box 801 drives the anti-loosening block 802 to move. The position of the anti-loosening block 802 can be adjusted according to the size of the plug 4, which is convenient for anti-loosening of plugs 4 of different sizes.

[0036] In this embodiment, a rubber pad is fixedly connected to the side of the anti-loosening block 802 that contacts the plug 4. The contact between the rubber pad and the plug 4 reduces the squeezing and wear of the plug 4 by the anti-loosening block 802.

[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
