Electrical connection device for photovoltaic module junction box

Abstract

The invention discloses an electrical connection device for a photovoltaic module junction box, and belongs to the technical field of solar photovoltaic modules. The electrical connection device comprises a pin and a socket spring plate, wherein the pin is integrated on a box cover; the socket spring plate is arranged on a box body; the pin can be inserted into the socket spring plate to form an electrical connection; the electrical connection device is characterized in that the socket spring plate comprises a first clamping plate and a second clamping plate; the tail ends of the first clamping plate and the second clamping plate are connected with each other to form a mounting part; the socket spring plate is connected to the box body through the mounting part; the second clamping plate sequentially comprises a bending part, a vertical part, a first guide part and a horizontal second guide part from the tail end to the head end; the bending part is connected with the first clamping plate; the first guide part inclines outwards; and a clamping part capable of clamping the pin is formed between the first clamping plate and the vertical part of the second clamping plate. According to the electrical connection device, the technical problems that the photovoltaic module junction box in the prior art is inconvenient to install and large in contact resistance are solved; the contact resistance can be effectively reduced; and the junction box is relatively convenient to install and change.

Description

technical field [0001] The invention relates to a photovoltaic module junction box, in particular to an electrical connection device used in the photovoltaic module junction box, and belongs to the technical field of solar photovoltaic modules. Background technique [0002] At present, the mainstream photovoltaic module junction boxes on the market are mostly in the form of a combination of box body and box cover, and electrical components such as bus bars and diodes are installed in the box body. With the emergence of smart components, the content of the photovoltaic module junction box has been enriched because of the intervention of the control circuit; at the same time, the form has also changed. Considering the possibility of failure of electronic components, in order to ensure the overall 25-year life of photovoltaic modules, when intelligent electronic components fail, they need to be replaced in time. Therefore, electronic components that are prone to failure are in...
