  • Patent number: 10886667
    Abstract: Electromagnetic shielding about both of electric connectors, which are in a mutually mated state, can be sufficiently carried out by a simple configuration. Shield wall portions composed of electrically-conductive members opposed to contact connecting portions (board connecting portions) of a plurality of contact members arranged in multipolar shapes are provided; electromagnetic shielding functions with respect to the contact connecting portions in the respective electric connectors are obtained well by the respective shield wall portions; and, when both of the electric connectors are mated with each other, the shield wall portions are configured to be in an inner/outer double disposition relation in which they are opposed to each other and efficiently block the gaps between the shield wall portions and wiring boards so that sufficient EMI measures can be expected.

  • Patent number: 9397421
    Abstract: A housing 11 comprises a lower receiver 11a extending from the back to front of a loading slot 15 and comprising a flat plate-like mounting surface Sa extending in the array direction of lower beams and on which the lower beams are mounted. Furthermore, the housing 11 comprises ribs 11b provided on the mounting surface Sa and extending from the back to front of the loading slot 15 to form grooves Za for retaining the lower beams. The ends of the ribs 11b that are situated in the front of the loading slot 15 are disposed closer to the back of the loading slot 15 than the end of the lower receiver 11a that is situated in the front of the loading slot 15.

  • Patent number: 9343831
    Abstract: Into one housing, another housing interlocks, and a penetrating hole into which a lock member for maintaining the interlocking state between the connectors is insertable and from which the inserted lock member is removable when releasing the interlocking state is formed in the other housing. A lock section is attached at a position corresponding to the penetrating hole in the inner wall of the one housing facing the other housing when the connectors are interlocked with each other, and is composed to be lockable with the lock member inserted into the penetrating hole. A connector is a pair of members attached to both ends of the lock section facing each other so as to interpose the lock section in between, and is connected to a circuit board positioned on the outside of the first housing in a state covering a portion of the one housing along with the lock section.

  • Patent number: 9231322
    Abstract: The operation of a lock member and the check thereof are easily and reliably enabled with a simple configuration while achieving downsizing. When a movable lock engagement part is moved along a lock guide part in a state in which a fixed lock latch part provided on either one of first and second electrical connectors is in an arrangement relation that the fixed lock latch part is overlapped with the lock guide part provided on the other one in a mating direction, the movable lock engagement part is engaged with or released from the fixed lock latch part. An operation of engaging or releasing the movable lock engagement part with/from the fixed lock latch part is carried out in a state in which the operation can be visually checked through a housing-operation opening and facing the electrical connectors.
