Optical electrical connector with improved heat dissipation performance

An optical electrical connector includes a casing, a printed circuit board, an electronic chip, a photoelectric conversion component, and a heat sink device. The casing includes an electrical port and an optical port. A receiving space is defined between the electrical port and the optical port. The printed circuit board extends longitudinally along a first direction. The printed circuit board includes a main body portion located in the receiving space and a front end portion exposed in the electrical port. The electronic chip, the photoelectric conversion component and the heat sink device are all accommodated in the receiving space. The electronic chip and the photoelectric conversion component are not only disposed on the printed circuit board, but also electrically connected to the printed circuit board. The heat sink device is disposed on the casing and faces the electronic chip for conducting the heat accumulated on the electronic chip.
