  • Publication number: 20200127410
    Abstract: A movable connector including a stationary housing to be fixed to a substrate, a movable housing configured capable of moving relative to the stationary housing, and a terminal including a stationary-side retained portion retained at the stationary housing, a movable-side retained portion retained at the movable housing, and an elastically deformable movable portion positioned between the stationary-side retained portion and the movable-side retained portion. Retention of the stationary-side retained portion with respect to the stationary housing is achieved by performing insert molding. Retention of the movable-side retained portion with respect to the movable housing is achieved by performing press-fitting.

  • Publication number: 20200127405
    Abstract: A movable connector including a stationary housing for fixing to a substrate, a movable housing capable of moving relative to the stationary housing, and a restriction fitting that has been integrated with the stationary housing. The restriction fitting includes a counterpart engagement portion. The counterpart engagement portion is configured to abut an engagement portion that is part of the movable housing from a connector upward direction so as to enable the engagement portion to be restrained in a restraint space that is a predetermined region. The counterpart engagement portion forms a through-pass section to permit the engagement portion to pass into the restraint space from outside.

  • Patent number: 10439312
    Abstract: To provide a flat-conductor connector that implements, with a simple structure, a function of preventing a flat conductor from coming out thereof. A flat-conductor connector includes a housing including a holding portion into which a flat conductor is inserted to be electrically connected. The housing includes a deformation guiding portion that comes into contact with the flat conductor and that causes a side edge portion of the flat conductor to be curved and deformed in a thickness direction and a retaining engagement portion that is located on a far side of the deformation guiding portion in an insertion direction of the flat conductor and that engages an edge of a recess formed in the side edge portion of the flat conductor that has returned from a state of being curved and deformed to its original shape, in a direction in which the flat conductor is to be pulled.

  • Patent number: 9105997
    Abstract: A connector which can absorb thermal expansion and contraction of a substrate, or positional deviation of the substrate, and which enables the male and female connectors thereof to be fitted to each other where the male and female connectors are inclined to each other. A male terminal of a male connector, and a female terminal of a female connector are slidable relative to each other when in contact with each other. The male terminal and the female terminal are rotatable relative to each other about a contact point when in contact with each other, and hence the male terminal and the female terminal can be attached and detached to and from each other at an arbitrary rotating position.

  • Patent number: 9011178
    Abstract: A connector which permits the resistance against the deformation of a shield to be increased and a method of manufacturing the connector. The shield is made up of an inner shield member disposed on the inner surface side of the shield and anouter shield member disposed on the outer surface side and, therefore, the strength of the shield can be increased by the double structure of the shield members. As a result of this, the shield is not deformed easily even in the case where an excessive external force is applied to the shield in the vertical direction or in the horizontal direction, for example, in inserting and extracting a mating connector into and out of the shield.

  • Publication number: 20130130534
    Abstract: A connector is configured such that parts of the connector bodies will be placed in openings of a substrate and that other parts of the connector bodies, i.e., parts placed on the substrate, will be equal in a height dimension to LEDs placed on the substrate. This makes it possible to reduce the overall thickness of the substrate including the connector bodies. Consequently, the substrate with the connectors mounted thereon can be installed without being restricted by substrate installation space even in a small device, which has a small substrate installation space in a thickness direction of the substrate.
