Abstract: A power jack (1) includes a dielectric housing (10) and a central terminal (20) received in the dielectric housing. The dielectric housing includes a mating face (11), a cavity (130) in the mating face and an anti-mating portion (15) formed on an inner face of the cavity for preventing full insertion of a non-complementary power plug having a smaller transmission power than that of the power jack. The central terminal includes a contact section (21) extending into the cavity for electrically connecting with a complementary power plug.

Abstract: An electrical connector (1) has an insulative housing (10), a plurality of contacts (20) received in the housing, an inner shell (30) surrounding the housing and an outer shell (40) surrounding the inner shell. The connector has a plurality of tabs (251, 263) extending inwardly therefrom. The tabs are constructed in the cover and bottom of the inner shell and can be latched to a mating connector. The out shell is conjoint to and overlaps the inner shell.

Abstract: A power connector (1) includes an insulative housing (10), a number of conductive contacts (20) received in the insulative housing, a first shell (30) enclosing the insulative housing and a second shell (40) enclosing the first shell. The insulative housing includes a base portion (101) and a tongue portion (103) extending forwardly from the base portion. The cross-section of each of the first and the second shells consists of a pair of straight sections (308, 408) parallel to each other and a pair of arcuate sections (308?, 408?) each connecting with the pair of straight sections.

Abstract: A power connector (1) includes an insulating housing (10), a number of contacts (20) received in the insulative housing, a first and a second shielding shells (30,40). The insulating housing has a base (101), and a tongue (103) extending horizontally from the base and including an upper mating face (1031) and a lower mating face (1032) parallel to the upper mating face. A number of receiving passages (105) are defined through the base toward the tongue. A plurality of receiving slots (104) extend from the upper mating face to the lower mating face to communicate with corresponding receiving passages. Each contact has a contact portion (201) received in corresponding receiving slot. The contact portion has a first and a second contact surfaces (202, 203) respectively exposed in the upper and the lower mating face.
