Abstract: An electrical connector includes an insulating body having a mating slot, which has a first inner wall and a second inner wall facing each other vertically. A ground terminal is fixed to the insulating body, and has a first contact portion exposed on a higher surface of the first inner wall. A grounding member has a second contact portion and a third contact portion both exposed on a lower surface of the first inner wall. The second contact portion is located closer to the second inner wall relative to the higher surface. In a vertical direction, the third contact portion is located farther away from the second inner wall relative to the higher surface. The second contact portion is grounded and conductively connected to the first electrical component inside the mating slot to form a first ground loop. The first contact portion is conductively connected to the first ground loop.

Abstract: An electrical connector module is used to mate with a mating connector module. The mating connector module has a first mating connector and a second mating connector. A first electrical connector is inserted with the first mating connector. One side of the first electrical connector is provided with a protruding block. A second electrical connector is inserted with the second mating connector. One side of the second electrical connector close to the first electrical connector is provided with a groove corresponding to the protruding block. The protruding block is accommodated in the groove. A length of the groove along an insertion direction is greater than a length of the protruding block along the insertion direction. The protruding block slides in the groove along the insertion direction.

Abstract: A heat sink assembly includes a casing having an opening, a main board accommodated in the casing, a heat sink mounted on the main board, an electrical connector mounted on the main board and exposed in the opening, a mating connector located outside the casing and connected to the electrical connector through the opening in a plugging manner, and a heat conductor, disposed inside the casing. The mating connector has a chip that is electrically connected to the electrical connector. One end of the heat conductor is connected to the heat sink, and the other end of the heat conductor is thermally connected to the electrical connector or the mating connector, so that heat generated by the chip during working can be transferred to the heat sink through the heat conductor, thereby reducing a temperature of the mating connector.
