Patent number: 7559773Abstract: The present invention prevents damage of adjacent mounting portions caused by heat at the time of mounting of contactors and further reduces the arrangement pitch of the contactors. An electrical connecting apparatus uses at least four types of contactors different in terms of at least the shapes of seat portions and the height positions of arm portions. Each of such contactors has a seat portion mounted on a mounting portion of a board, an arm portion extending in the left-right direction from the lower end of the seat portion, and a probe tip portion extending downward from the tip end portion of the arm portion and having a probe tip at the lower end. These contactors are mounted in parallel in a cantilevered manner alternately in the front-back direction with the mounting positions to the board displaced in the left-right direction.Type: GrantFiled: October 7, 2008Date of Patent: July 14, 2009Assignee: Kabushiki Kaisha Nihon MicronicsInventor: Yoshiei Hasegawa

Patent number: 7532020Abstract: A probe assembly having a plurality of probes, each of which is secured to an anchor portion on a probe base plate, extends in a direction apart from the anchor portion through a fulcrum, has a tip at the front end thereof, and the tip is elastically deformable at its front end side when pressed against a corresponding electrode pad. Two probe groups are constituted: in the first group, the tips are arranged on one side of an imaginary straight line of the probe base plate, while in the second probe group, the tips are arranged on the other side of the imaginary straight line. The numbers of the probes of both probe groups are different, and a part of the probes forming one probe group with more probes are arranged in the opposite direction to that of the other probes of the same probe group.Type: GrantFiled: June 4, 2007Date of Patent: May 12, 2009Assignee: Kabushiki Kaisha Nihon MicronicsInventors: Yoshiei Hasegawa, Masashi Hasegawa

Patent number: 7377788Abstract: An electrical connecting apparatus comprises: a base plate provided with a first and a second mounting portion groups respectively having a plurality of first and second mounting portions arranged so as to be alternately positioned in a first direction; and a first and a second contact groups respectively having a plurality of first and second contacts individually mounted on the first and second mounting portions and in a cantilever state, the first and second contacts being displaced from each other in a second direction intersecting the first direction at the mounting positions on the base plate. This prevents any damage to adjacent mounting portions due to heat at the time of mounting the contacts, so that an arrangement pitch of the contacts can be made small.Type: GrantFiled: July 11, 2006Date of Patent: May 27, 2008Assignee: Kabushiki Kaisha Nihon MicronicsInventor: Yoshiei Hasegawa
