Description

Solar panel back shell with wire clamping function

Technical Field

The utility model relates to the technical field of solar panel shells, in particular to a solar panel back shell with a wire clamping function.

Background

It is known that an assembled unit of a plurality of solar cells in a solar panel (also called a solar cell module) is a core part of a solar power generation system and is the most important part of the solar power generation system. The solar panel is structurally characterized by mainly comprising toughened glass, EVA (ethylene-vinyl acetate copolymer) (used for bonding and fixing the toughened glass and the battery piece), the battery piece, a back shell, aluminum alloy, a junction box and silica gel. The back shell is sealed, insulated and waterproof, TPT, TPE and other materials are generally used, and external wires are generally penetrated from the back shell and then connected with the internal junction box.

At present, the existing back shell is generally only provided with a threading hole aiming at the penetration of an external electric wire, so that the electric wire can penetrate into the interior and other structures can not be arranged. When the wires and the internal junction box are connected, the wires are pulled by the external action, so that the wires and the junction box are easily loosened or even disconnected, and the solar panel is in failure in power transmission. And because most solar panels are used outdoors, no matter the solar panels are installed in construction or in the use process, the situation that wires are pulled can not occur, and the wire connection is disconnected due to the pulling, so that the application of the solar panels is hindered.
