A press-button junction box dedicated to cadmium telluride thin film components

Abstract

The invention discloses a dedicated press-clip type wiring box for a cadmium telluride thin film assembly. The wiring box includes a box body, a bottom board and a pedestal buckled to each other so asto form a mounting cavity. A diode is mounted in the mounting cavity. The box body is provided with a sunken mounting groove used for accommodating the diode. The mounting groove is provided with a boss protruding from the box body and formed on the back face of the box body. A plurality of radiating fins are arranged on the periphery of the boss. The box body is provided with a wire slot reaching the mounting groove from the edge of the box body. A cable is connected with the diode via the wire slot. The bottom board is in a shape corresponding to that of the mounting groove and can be nested in the mounting groove so as to form a plane with the bottom part of the box body. The middle part of the bottom board is provided with a sub box body which has a hollow bottom part. The box body with provided with a neck within the mounting groove. When the box body buckles with the bottom board, the neck is disposed in the bottom hollow part of the sub box. The edge of the bottom board is connected with a wire slot cover board capable of being spliced with the wire slot. The pedestal is provided with a pin, so that the pin is in associated connection with the neck when the pedestal is nested in the hollow part of the sub box.

Description

technical field [0001] The invention relates to the matching field of cadmium telluride thin film components, in particular to a junction box for cadmium telluride thin film components. Background technique [0002] In recent years, the research directions of solar cells are high conversion efficiency, low cost and high stability. Therefore, thin-film solar cells represented by cadmium telluride thin-film solar cells have attracted much attention, and many organizations and companies have begun research and testing. Cadmium telluride thin-film solar cells are referred to as CdTe cells. It is a p-type CdTe and n Cd-type heterojunction-based thin-film solar cells, cadmium telluride thin-film solar cells are the easiest to manufacture in solar cells, so it has the fastest progress towards commercialization, due to the high conversion efficiency of cadmium telluride cells, current and voltage bias Large, so that the junction box of traditional crystalline silicon solar cells an...
