  • Patent number: 11894639
    Abstract: There is provided a coaxial connector that can suitably bias a movable insulator to the side of a socket and maintain matched impedance. The coaxial connector includes a movable insulator that is fitted in a central conductor so as to be slidable and is housed in an insulator housing so as to be movable in an axial direction; and a biasing rubber member that is interposed between a partition disposed in the recesses of the insulator housing and the movable insulator. When the biasing rubber member connects the socket to the plug, the movable insulator is pushed in by a pushing force from a socket, and elastic pillars are bent in an arc shape.

  • Patent number: 11398706
    Abstract: A connector includes: an internal contact disposed at an inner position in a radial direction; an external contact disposed at an outer position in the radial direction; and an insulator disposed between the internal and external contacts. At least one of the internal and external contacts includes, on one side in the axial direction, a mating part to be mated with a corresponding counterpart contact at a predetermined radial contact pressure. The insulator includes a first insulator part exposed to the one side in the axial direction, and a second insulator part disposed on the other side in the axial direction relative to the first insulator part. The first insulator part is made of an elastic material capable of being easily deformed elastically in the radial direction as compared to the second insulator part.

  • Patent number: 6596355
    Abstract: A packaging material is composed of a heat resistant base layer, a sealant layer, and a resin layer disposed at least a portion between the heat-resistant base layer and the sealant layer. The resin layer is composed of a resin material having a predetermined strength in a non-heated temperature state of less than a room temperature and this strength is lowered in a high temperature state heated, for example, by a microwave oven. Such packaging material can be effectively utilized for many kinds of packaging bags or containers with the sealant layer being disposed to the inner content side of the bag or container.
