Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to a photovoltaic distribution box. Background Technology

[0002] Photovoltaic distribution boxes are important electrical devices in photovoltaic power generation systems, enabling functions such as power distribution and protection.

[0003] Existing photovoltaic distribution boxes come in two types: one is a larger floor-standing type with a complete panel at the bottom to prevent water ingress, and cables enter from the side; the other is a smaller wall-mounted type, which is hung on a utility pole or wall and has multiple cable inlets at the bottom for cables to pass through. However, in order to accommodate cables of different diameters or numbers, the inlet diameter is generally set relatively large, so even after a small number or small diameter cable bundles pass through, there are still large gaps in the inlet. Since photovoltaic distribution boxes may be installed in dark locations, and small animals or insects such as rats may exist in the surrounding area, there is a possibility that animals or insects may crawl into the box through the gaps. Once they crawl into the box, they may damage the internal components, posing a safety hazard. Utility Model Content

[0004] This utility model provides a photovoltaic distribution box that can overcome some or all the defects of the prior art.

[0005] According to the present invention, a photovoltaic distribution box includes a main body, the main body includes a box body, the box body has a receiving cavity; the box body is provided with a plurality of inlet ports communicating with the receiving cavity;

[0006] A clamping assembly is provided at the cable inlet; the clamping assembly includes a first clamping plate and a second clamping plate that are arc-shaped and used to clamp the cable; a vertical pole is provided at the cable inlet; the first clamping plate and the second clamping plate are rotatably engaged with the vertical pole at one end, and are used to seal the remaining gaps in the cable inlet while rotating to clamp the cable.

[0007] The clamping assembly of this invention can seal the cable inlet, and a clamping area can be formed between the arc-shaped first clamping piece and the second clamping piece. When it is necessary to thread the cable, the cable can pass through the clamping area between the first clamping piece and the second clamping piece for clamping. While clamping the cable, the gap of any excess opening is sealed. While firmly clamping the cable, it can also prevent external animals and insects from entering, thereby improving safety.

[0008] Preferably, both the first clamping plate and the second clamping plate have a through hole at one end for the upright to pass through; the first clamping plate and the second clamping plate are stacked one on top of the other and their concave surfaces face each other; the upright is provided with a nut and a thread for the nut to engage.

[0009] In this invention, the use of threads and nuts allows for adjustment of the contact tightness of the stacked first and second clamping pieces, facilitating position adjustment and pressing them together after adjustment. This prevents external forces from causing the first and second clamping pieces to separate and widen the gap at the wire inlet. Furthermore, the stacked first and second clamping pieces can be stacked with the first and second clamping pieces of adjacent fastening components after separation, resulting in a compact design that reduces space occupation.

[0010] Preferably, an anti-slip surface is provided at the end face where the first clamping piece and the second clamping piece contact.

[0011] In this invention, the anti-slip surface increases the friction between the first clamping piece and the second clamping piece, thereby preventing them from easily separating and causing the clamping area to expand.

[0012] Preferably, both the first clamping plate and the second clamping plate have elastic pieces on the side that contacts the cable.

[0013] In this invention, the elastic sheet allows the first and second clamping sheets to have flexible contact with the cable when clamping it, thereby preventing damage to the cable.

[0014] Preferably, the cavity is provided with a partition to divide the cavity into two sub-cavities; the partition is provided with a threading port that runs through the two sub-cavities.

[0015] In this invention, the partition and the cable pass-through port allow the two sub-cavities of the receiving cavity to be used to install devices such as knife switches and electronic watches, and the cable pass-through port allows for classified placement.

[0016] Preferably, the enclosure has a door for sealing the receiving cavity, and the door has a transparent observation port.

[0017] In this invention, the transparent observation port allows the interior of the box to be observed from the outside, thus facilitating daily inspections. Attached Figure Description
