  • Publication number: 20040248444
    Abstract: A card edge connector (1) includes an insulative housing (10), a number of electrical contacts (20), and a pair of latch members (40). The insulative housing defines a mating face (11), a slot (110) in the mating face, a number of passageways (112) communicating with the slot, and a pair of support arms (13) extending upwardly from each end thereof. The electrical contacts are received in the passageways of the insulative housing. Each latch member is piovtably moveable with respect to the insulative housing from a locked position to a released position and includes a main section (41) pivotably assembled to the arms on the end of the insulative housing and a locking section (44) extending from the main section at an acute angle relative to the mating face of the insulative housing in the locked position.

  • Patent number: 6695644
    Abstract: A power connector (1) includes an insulative housing (2), a first conductive contact (5) and a second conductive contact (6). The insulative housing includes a receiving space (3) defined inwardly from a front surface of the housing and an inner portion (22) bounded on its sides by the receiving space. Each contact includes a main body (51, 61) assembled in the rear wall of the housing and a plurality of mating portions (53, 63). The mating portions are assembled in the housing and partly exposed in the receiving space. The mating portions of the first conductive contact are arranged on an outer circle. The mating portions of the second conductive contact are arranged on an inner circle inside the outer circle.
