Patent number: 5647749Abstract: A right angled header connector assembly including a main housing having a circuit board connecting face from which respective circuit board connecting portions protrude horizontally rearward and forward therefrom for reflow soldering to the circuit board and a transverse mating face. A subhousing is releasably attachable to the main housing to extend forward at the mating face surrounding the mating portions of the contact elements and in adjacent covering relation to the forward protruding circuit board connecting portions subsequent to the reflow soldering step. Release of the subhousing from the mating face, enables access to the forward protruding circuit board connecting portions for the reflow soldering step, unimpeded by said subhousing.Type: GrantFiled: September 19, 1994Date of Patent: July 15, 1997Assignee: Kel CorporationInventors: Kiyoshi Atoh, Etsuro Doi, Shoichi Mochizuki, Mazakazu Koiso

Patent number: 5591036Abstract: An electrical connector of a right angle header type including a housing with a series of contact members having connecting portions and lead portions at mating and rear faces, respectively, the lead portions being bent through 90 degrees forming medial portions extending rearward from the rear face and board connecting portions extending downward so that free ends of the board connecting portions are insertable into respective connecting through-holes of a circuit board. A lead portion retaining member having lead portion locating groves on a lower face is releasably attached to the housing to extend over the medial portions to prevent upward movement thereof during insertion of the end portions into the respective connecting through-holes, thereby obviating risk of misjudgement that the connector is correctly installed on the circuit board.Type: GrantFiled: February 21, 1995Date of Patent: January 7, 1997Assignee: Kel CorporationInventors: Etsuro Doi, Kiyoshi Atoh, Shoichi Mochizuki, Masakazu Koiso

Patent number: 5536182Abstract: An insulation displacement connector for flat cable comprising an insulating housing and one piece terminals, each having a mating contact portion and a slotted plate wire connecting portion joined by a conducting lead portion. All the mating contact portions are mounted in a common plane at the mating face as a row extending transversely of a mating direction and the wire connecting portions are arranged as four rows extending transversely of the cable axis and at predetermined spacings apart in an axially rearward direction.Type: GrantFiled: September 19, 1994Date of Patent: July 16, 1996Assignee: Kel CorporationInventors: Kiyoshi Atoh, Etsuro Doi, Shoichi Mochizuki, Mazakazu Koiso

Patent number: 5263867Abstract: A surface mount connector comprises two assemblable housing parts for engagement with a circuit board and for mating with a complementary connector respectively. A series of contacts are anchored in the board engaging part and the other mating part is provided with contact locating surface portions which engage and press the contacts into a coplanar circuit board engaging position when the two housing parts are assembled together.Type: GrantFiled: November 4, 1991Date of Patent: November 23, 1993Assignee: Kel CorporationInventors: Etsuro Doi, Kiyoshi Atoh, Mutsuo Hatanaka

Patent number: 5201883Abstract: An electrical plug connector comprises an insulating plastic base and a first and second series of elongate metal contact security respective opposite major faces of the base by an in-molding step so that respective back surfaces of the contacts and parts of their side surfaces are embedded in the plastic material while connecting surfaces are exposed for engagement with a complementary connector. During the in-molding process a cavity is formed between the two series of contacts at a rear end of the base by a mold member supporting rear ends of the contacts of respective series in spaced apart, parallel relation while front ends of the contacts are supported by attachment to respective carrier strips. A plug is force fitted into the cavity subsequent to molding supporting the rear ends of the contacts. Leading, front ends of the contacts have laterally extending anchoring portions and tapering, inwardly extending tips completely covered by the plastic material to ensure double securement to the base.Type: GrantFiled: November 27, 1991Date of Patent: April 13, 1993Assignee: KEL CorporationInventors: Kiyoshi Atoh, Shinji Tanabe

Patent number: 5177671Abstract: A chip carrier socket comprises a one piece insulating housing with a rectangular frame-like body portion surrounding a rectangular base-plate. Rows of contacts are force-fitted in cavities in the body portion with contact spring portions extending inwardly for electrical connection to leads on respective sides of a chip carrier inserted in the socket and with rows of soldering tabs extending inwardly at the circuit board engaging face for reflow soldering to pads of the circuit board. The base-plate is supported on the body portion with respective perimetrical edges thereof located spaced apart from the respective adjacent sides of the body portion, defining therewith apertures aligned over the respective rows of solder tabs, by bridge portions which extend between respective corners of the base-plate and adjacent respective corners of the frame-like body portion without obstruction of the field of view along the apertures.Type: GrantFiled: October 4, 1991Date of Patent: January 5, 1993Assignee: Kel CorporationInventor: Kiyoshi Atoh

Patent number: 5133670Abstract: A surface mount connector comprises an insulating housing body in which a series of electrical contacts are secured with contact leg portions thereof extending externally alongside a housing face and a contact aligning member for assembly with the housing by forcible insertion between the housing face and the contact leg portions thereby urging the contact leg portions away from the housing face to bring contact ends thereof into a common circuit board engaging plane and a predetermined spaced apart relation. The guide means comprises an insulating bar formed with a row of ribs defining between them contact receiving alignment channels at the predetermined spacing. Ears extend from the housing face at respective opposite ends of the series of contacts and have respective recesses aligned with each other and the contact leg portions for receiving the aligning member as a force fit to assemble the aligning member with the housing.Type: GrantFiled: March 18, 1991Date of Patent: July 28, 1992Assignee: Kel CorporationInventors: Etsuro Doi, Kiyoshi Atoh, Mutsuo Hatanaka
