Patent number: 7914329Abstract: A card connector comprises a plurality of contacts, a frame, a shell and a locator. Each of the plurality of contacts comprises a first portion extending in a first direction and a second portion extending in a second direction perpendicular to the first direction. Each contact has substantially an L-like shape. The frame has a front end portion and a rear end portion. The rear end portion holds, in part, the first portions of the contacts. The first portions extend into a space defined by the frame toward the front end portion in the first direction. The second portions extend away from the frame in the second direction. The shell is attached to the frame. The shell shields, in part, the second portions of the contacts. The locator is supported by the shell. The locator is distinct from the shell. The locator holds, in part, the second portions of the contacts so that the second portions penetrate the locator.Type: GrantFiled: February 20, 2009Date of Patent: March 29, 2011Assignee: Japan Aviation Electronics Industry, LimitedInventors: Yosuke Honda, Takamitsu Wada
