Patent number: 10431916Abstract: 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.Type: GrantFiled: May 22, 2018Date of Patent: October 1, 2019Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Narutoshi Hoshino, Masanori Ohkita, Katsutoshi Tohjo

Patent number: 9735503Abstract: 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.Type: GrantFiled: August 27, 2013Date of Patent: August 15, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventor: Katsutoshi Tohjo
