Abstract: A backplane connector has a housing, a first insulative base, a second insulative base, multiple first terminals, multiple second terminals and multiple third terminals. Each of the insulative bases is mounted in the housing and is formed into one-piece. The first terminals are mounted on the first insulative base.

Abstract: An electrical connector has an insulative housing, terminals and two fastening assemblies. Each fastening assembly has a latching member and a bracket. The latching member is mounted movably on the insulative housing and has a hooking section to hook on a memory module. The bracket is mounted pivotally on the latching member and has a soldering section soldered on a PCB. Because the bracket is pivotally adjustable on the latching member, the electrical connector may be mounted easily on different PCBs with different tolerances.
