  • Patent number: 5647749
    Abstract: 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.

  • Patent number: 5516297
    Abstract: A surface mount electrical connector having lead portions of first and second series of terminals extending in alternating closely spaced parallel relation across a circuit board from a rear face of a connector housing. The lead portions have transverse soldering portions on respective free ends and the lead porions of the second series are longer than those of the first series and the lead portion of each series are of equal length so that the soldering portions of the first and second series are located in first and second rows with the first row being closer to the housing than the second row. The soldering potions of the first row have respective upstanding heater engaging portions so that the heater can be brought into engagement therewith without interfering with adjacent lead portions or with soldering portions of the other row.
