The present disclosure discloses an electrical connector which comprises a shell, a first wafer group and a second wafer group. The shell comprises: a first frame portion defining a first slot; a second frame portion defining a second slot; a first supporting portion positioned at a first side of the shell; a second supporting portion positioned at a second side of the shell, and a bridging portion connecting the first frame portion and the second frame portion. The bridging portion, the first frame portion and the second frame portion cooperatively define an air flow channel. The first wafer group is assembled to the first slot. The second wafer group is assembled to the second slot.

An electrical connection device and a board-to-board electrical connection assembly, the board-to-board electrical connection assembly comprises an electrical connection device, a first circuit board and a second circuit board. The electrical connection device comprises a support frame and an adapter circuit board, the support frame has a top portion and a bottom portion. The adapter circuit board comprises an upper end portion retained to the top portion of the support frame, a lower end portion retained to the bottom portion of the support frame and a side portion positioned between the upper end portion and the lower end portion, the upper end portion comprises a first connector, the lower end portion comprises a second connector. The first circuit board is provided with a first mating connector for mating with the first connector. The second circuit board is provided with a second mating connector for mating with the second connector.

A double sided edge connector is provided including a housing formed from a pair of substantially identical hermaphroditic housing halves and aligned pairs of electrical terminals. Each housing half includes a plurality of parallel spaced apart contact guides defining contact receptacles therebetween. Each housing half further includes a longitudinally extending contact retaining wall adjacent the top of the housing half and defining a portion of each contact receptacle. Each terminal includes a central mounting portion, a solder tail at one end and a contact beam at the other end. The contact beam is of a double bent configuration to provide anti-overstress protection to the terminals in use. The terminals are heat staked into the respective receptacles such that the end of the each contact beam is biased against the contact retaining wall. The substantially identical housing halves with the terminals heat staked therein are hermaphroditically mated and are heat staked together.

A new and improved heat-dissipating socket connector for connecting individual leads of a leaded module to individual circuits on a printed circuit board comprises a unitary molded dielectric frame including a module-receiving recess. The frame is cantedly mounted on the circuit board with the recess disposed at an angle with respect to the printed board surface. Compliant terminals are mounted in generally open terminal receiving cavities within the frame which are adapted to engage side portions of leads on an inserted module with high contact pressure in an anti-overstress manner. Openings within the frame together with an exposed terminal mounting arrangement, provide ventilation and airflow exposure for portions of the connector and module susceptible to the generation of high temperatures in use. The overall arrangement provides enhanced electrical reliability by reducing the possibilty of heat induced failures. The new and improved socket connector does not require increased board surface area and provides for full visual inspection for solder connections between connector terminals and printed circuits.

A low insertion force mating electrical contact structure is provided in a male terminal including a final contact portion and a forwardly extending lead-in portion having a gradual twisted cross section relative to the final contact portion. In a preferred embodiment, the male terminal is adapted to mate with a dual contact cantilever spring arm female terminal. Opposed smooth-milled surfaces on the male terminal extending through the lead-in portion to the final contact portion engage the female contact portions and gradually cam the female contacts outwardly to provide reduced insertion forces on the male pin during insertion. Varying the rate of change in the twist along the lead-in portion can define camming surfaces on the male terminal effective to substantially reduce the lifting force component of the insertion force so that the peak insertion force for the mating contact structure approaches only the frictional sliding force between the male and female contact portions, associated with the final stages of insertion and mating.
