Abstract: The present disclosure provides a heat spreader and a power module. The heat spreader comprises: a base plate comprising a first surface and a second surface opposite to the first surface; an insulating frame fixedly connected to the first surface of the base plate; and an insulating material attached to at least a part of a surface of the insulating frame. The present disclosure can effectively satisfy design requirements for both heat dissipation and insulation, and significantly increase a layout space for a printed circuit board.

Abstract: The present invention provides a mounting bracket for a junction box utilized for solar cell, a junction box with the mounting bracket, and the solar cell module. The mounting bracket for the junction box comprises a joint arm, an insert strip, and a hook. The insert strip comprises a first elastic strip connecting with the joint arm, a joint strip connecting with the first elastic strip and bending towards the joint arm, and a second elastic strip connecting with the joint arm. The insert strip is used for inserting into the frame. At least one of the first and the second elastic strips of the insert strip comprise a first elastic block.

Abstract: The present invention provides a junction box, which comprises a base, a housing, and a PCB in the housing, a hole is set in the base, and a supporting frame is set on the base; a terminal corresponding to the supporting frame is set on the PCB; a bus bar can pass through the hole and is set on the supporting frame; the terminal is electrically connected with the PCB; when the housing is coupled to the base, the terminal is pressed to fit the corresponding supporting frame; and the PCB is electrically connected to the bus bar through the terminal. The advantage of the present invention is that the PCB is set on the housing. The supporting frame is matched to the terminal, which can electrically connect the bus bar and the PCB, and install the bus bar, to avoid using screws.
