  • Patent number: 8251753
    Abstract: An electrical connector (100) includes an insulative housing (1) and at least one contact (4) assembled to the insulative housing. The insulative housing defines an insertion hole (15) along a mating direction and a passageway (131) opening at an upper face (10) thereof. The passageway has a first slot (132) at a side face of the insulative housing and a second slot (133) positioned between the first slot and the insertion hole along a transverse direction which is perpendicular to the mating direction. The second slot communicates with the insertion hole. The insulative housing includes a supporting part (134) between the first slot and the second slot. The at least one contact is assembled to the insulative housing from the upper face.

  • Patent number: 7794253
    Abstract: A coaxial connector for receipt of a central contact of a complementary coaxial connector to be inserted therein, comprising an insulative case including an upper insulative case portion and a lower insulative case portion; an upper fixed contact, a movable contact and a bottom fixed contact essentially stacked in the space section; the upper fixed contact arranged to be sandwiched by the upper insulative case portion and the lower insulative case portion, the upper fixed contact having a planar contact part along a lengthwise direction; the movable contact having a central planar contact section, the central planar contact section arranged to initially come into contact with the contact part of the upper fixed contact; wherein the contact section of the movable contact is arranged to be movable from a position at which the movable contact is in contact with the upper fixed contact to a position at which the movable contact is separated from the upper fixed contact while not coming into contact with the botto
