Abstract: The present disclosure discloses an explosion-proof housing and an electrical device. The explosion-proof housing includes a first housing body, a second housing body, a fastener, and a limit member. The first housing body has a first mounting hole. The second housing body covers the first housing body and has a second mounting hole. The fastener passes through the first mounting hole and the second mounting hole to connect the first housing body to the second housing body. The limit member is disposed between the first mounting hole and the fastener and has a first state and a second state. In the first state, the limit member is adapted to limit a limit head of the fastener outside the first mounting hole. In the second state, at least part of the limit member is disengaged from the limit head to allow the limit head to enter into the first mounting hole.

Abstract: The present disclosure relates to solar cells for a shingled solar cell module, a shingled solar cell module, and a method of making solar cells for the shingled solar cell module. Said solar cell has a front side and a back side, a plurality of front side busbars being arranged on the front side, a plurality of back side busbars being arranged on the back side, the solar cell comprising a plurality of sections, each section comprising a front side busbar and a back side busbar located at edges thereof, the front side busbar of at least one section of the solar cell having an extension at one end or both ends, the extension extending along another edge of said at least one section intersecting with the above-mentioned edges. The shingled solar cell module is fabricated from solar cell strips split from the solar cell.
