Abstract: A lever-style de-latch mechanism for a pluggable electronic module, such as an SFP MSA fiber optic transceiver or other pluggable optoelectronic or electronic module. The mechanism is easily accessible to an operator and does not require any tools to operate. The mechanism uses rotational motion of a lever about a horizontal axis transverse to a horizontal direction of elongation of a module, or about a vertical axis (relative to a module extending in a horizontal plane), to cause translational motion of the de-latch actuator. Mechanisms including both T and bail latch style levers are provided. The lever may be adjacent to, or extend beyond, the front/face of the module's housing for tool-free accessibility and operation. The mechanism may allow the user to apply force to actuate the mechanism in a direction that does not oppose a withdrawal and/or module ejection force.

Abstract: An electrical edge connector housing (1), for mounting onto a printed circuit board substrate (100), has walls that form a plurality of slots (3) and a respective plurality of chambers (2). Each slot (3) is positioned on an opposite side of a substrate receiving groove (13) from a chamber (2). Each slot (3) and chamber (2) receives a contact (18) therein for connection to the substrate (101) received within the groove (13). A retention clip (40) cooperates with an alignment block (50) to align and retain the substrate (101) within the housing (1).

Abstract: An adapter assembly (20) for electrical connection between a small outline integrated circuit (SOIC) (25) and a remote receptacle connector (87) via a cable including a plurality of electrical conductors (23) comprises a nonconductive adapter housing (21) providing a plurality of spaced-apart slots (39) for receiving a plurality of contacts (22). The SOIC (25) being received in a cavity (50) at the bottom of the adapter housing (21), is retained within the cavity (50) by retention teeth (57) engaging respective side retention areas (54) located between each two adjacent leads (24) of the SOIC (25), and by a pair of retention members (55) engaging respective end retention areas (56) of the SOIC (25). A removable clip (26) is locked over the adapter housing (21). Each contact (22) being received in the respective slot (39), engages a respective lead (24) of the SOIC (25) by its lower portion (61). An upper portion (62) of each contact (22) terminates the respective electrical conductor (23).

Abstract: An electrical connector (20) for interposition between an electronic component (2) and a printed circuit card (14), electrically to connect contact pads (10) of the electronic component (2) to contact pads (18) of the circuit card (14), comprises a pair of superposed insulating plates (22 and 24) connected together by means of interengaging pins and sockets (66, 70 and 68, 72). The insulating plates (22 and 24) cooperate to define cavities (30) receiving spring contact elements (40) each having a nose (50) projecting through an opening (36) in a respective cuter surface (26 or 28) of the plates (22 and 24) for engagement with the contact pads (10 and 18). One half of each cavity (30) is defined by one of the plates (22 and 24) the other half being defined by the other of the plates (22 and 24). The cavities ( 30) have end walls (62 and 64) between which the contact elements (40) are compressed by engagement with the pads (10) and (18) so that the noses (50) wipe the contact surfaces of the pads (10 and 18).
