  • Publication number: 20140134885
    Abstract: An electrical connector mountable on a printed circuit board and adapted for mating with a complementary connector, includes an insulating housing and a plurality of contacts. The insulating housing defines a base section, an upper and a lower walls extending forwardly from the base section, and a receiving space defined between the upper and the lower walls. Each contact has a main portion, a contacting portion extending from the main portion and exposed to the receiving space, and a tail portion extending outside of the insulating housing. A positioning protrusion is formed on an inside face of the lower wall and extends into the receiving space, and defines a slanted guiding surface therealong opposing to the upper wall to guide an insertion or rejection of the complementary connector.

  • Patent number: 8702445
    Abstract: An electrical connector for mounting onto a printed circuit board includes an insulating housing and a plurality of power contacts. The insulating housing has a number of dividing walls and a number of receiving passageways defined between the dividing walls. The plurality of power contacts is received in the corresponding receiving passageways, respectively. One of the dividing walls defines a heat dissipation cutout thereon for heat dissipation purpose.

  • Patent number: 8662913
    Abstract: An electrical connector (100) for engaging with a complementary connector, includes an insulating housing (10) and pairs of power contacts (20) assembled in the insulating housing. The insulating housing defines a number of receiving passageways (11) extending therethrough along a front-to-back direction. The pairs of power contacts are received in corresponding receiving passageways, respectively. The insulating housing defines at least one hole (13) between two adjacent receiving passageways. The at least one hole communicates with the two adjacent receiving passageways for heat dissipation purposes.
