  • Patent number: 10431916
    Abstract: Housing includes: insertion part into which a connection target is inserted; a plurality of first grooves provided inside insertion part so as to align along an alignment direction being perpendicular to the insertion direction of the connection target, first contact parts being respectively disposed in first grooves; a plurality of second grooves provided inside insertion part so as to oppose to first grooves, second contact parts being respectively disposed in second grooves; first partition wall partitioning adjacent first contact parts; and second partition wall partitioning adjacent second contact parts. At least one of first partition wall and second partition wall has a height dimension in a direction perpendicular to both the insertion direction and the alignment direction, the height dimension being smaller at least at one end in the alignment direction than at a portion between opposite ends in the alignment direction in order to reduce capacitance between contact parts.

  • Patent number: 10008798
    Abstract: A connector having an insertion part into which a connection target is inserted; a plurality of first grooves provided inside insertion part so as to align along an alignment direction being perpendicular to the insertion direction of the connection target, first contact parts being respectively disposed in first grooves; a plurality of second grooves provided inside insertion part so as to oppose to first grooves, second contact parts being respectively disposed in second grooves; first partition wall partitioning adjacent first contact parts; and second partition wall partitioning adjacent second contact parts. At least one of the partition walls includes an elongated protrusion on its top surface in order to reduce capacitance between adjacent contact parts.

  • Patent number: 9735503
    Abstract: A connector includes: a housing 3 accommodating at least one of a conductive contact 5; an insertion opening 4 to which a flat cable 2 can be inserted, the insertion opening 4 being provided in front part of the housing 3 and being defined by upper and lower walls 33 and 32 of the housing 3 at the top and bottom; and a lever 6 which is provided in the back part of the housing 3 and is turned to bring the contacts 5 into pressure contact with the flat cable 2 and establish electrical continuity therebetween. The contact 5 includes a first contact 5A which is engaged with the housing 3 at such a position that press-fit forces produced in the direction orthogonal to the press-fit direction when the contact 5A is press-fitted into the housing 3 are not in the same straight line.

  • Patent number: 9190757
    Abstract: A connector 10 includes: a housing 30 into which a cable 20 is to be inserted; first contacts 40 housed in the housing 30 and having contact portions 46 with a short effective fitting length; and second contacts 50 housed in the housing 30 and having contact portions 56 with a long effective fitting length. Then, the first contacts 40 are arranged on both ends in a width direction Y of the housing 30, and the contact portions 56 with the long effective fitting length of the second contacts 50 arranged so as to adjoin insides in the width direction Y of the first contacts 40 arranged on both ends, are engaged with engagement portions 22 of the cable 20.
