Abstract: An electrical connector assembly (100) for connecting memory modules (200) to a printed circuit board (PCB) (300), includes a first and second connectors (10, 20) respectively mounted on two opposite surfaces of the PCB. The first and second connectors each defines an insulative housing (11/21) and a plurality of contacts retained in the housing. Each of the housing defines a front face and an inserted slot (13/23) running through the front face along a longitudinal direction. Each of the contacts defines an elastic arm partly projecting into the inserted slot and a soldering leg connecting to the PCB. The housing of the first connector provides a cavity (172) at a bottom portion thereof. A part of the second connector projects beyond the top surface of the PCB, and the soldering legs of the second connector run through the opposite surfaces of the PCB and enter into the cavity.

Abstract: A card edge connector assembly for connecting a pair of electrical cards to a printed circuit board includes an upper connector and a lower connector. The upper connector includes a first insulative housing with a plurality of first terminals mounted therein. The first insulative housing defines a recess thereunder and extending from a first front face of the first insulative housing thereof. The lower connector includes a second insulative housing with a plurality of second terminals mounted therein and received in said recess under the upper connector. The second insulative housing defines a second front face which is in alignment with the first front face in a vertical direction.

Abstract: An electrical connector assembly (100) for connecting memory modules (200) to a PCB (300), includes a first connector (10) mounted on a top surface (301) of the PCB and a second connector (200) mounted on a bottom surface (302) of the PCB. The first and second connector each defines an insulative housing (11/21) and a plurality of contacts received and retained in the housing. Each of the housing defines a front face and an inserted slot (13/23) for receiving the memory module running through the front face along a longitudinal direction. Each of the contacts defines an elastic arm partly projecting into the inserted slot and a soldering leg connecting to the PCB. The housing of the first connector defines a raised portion (171) projecting downwards from a bottom face (17) thereof, thereby providing a cavity (172) at a bottom portion of the first connector.

Abstract: An electrical connector includes a main board (5) with a first card edge connector (1) mounted thereon, a sub-board (6) with a second card edge connector (2) mounted thereon, and a pair of complementary board to board connectors (3, 4) mounted on the main board (5) and the sub-board (6) respectively. The first and second card edge connectors (1, 2) are aligned with each other in a vertical direction and the second card edge connector (2) is on top of the first card edge connector (1).

Abstract: An electrical connector assembly comprises an upper connector and a lower connector stacked vertically for electrically connecting two memory modules to a PCB. Said upper connector includes a plurality of first contacts having a plurality of horizontal first soldering legs which are soldered on a top surface of the PCB by SMT. Said lower connector includes a plurality of second contacts having a plurality of second vertical second soldering legs which are soldered on a bottom surface of the PCB. Said bottom surface of the PCB has a plurality of soldering holes which are not getting through the top surface of the PCB for retaining said vertical second soldering legs therein so as to provide an available soldering area for said horizontal first soldering legs on the top surface of the PCB. Said electrical connector assembly reduces the size and the occupancy on said PCB efficiently, which saves the space of the PCB.

Abstract: An electrical connector (100) includes an insulative housing (1), a plurality of contacts (2) received in the housing and a pair of latching members (3) assembled on the housing. The insulative housing defines a longitudinal main body (10) with an inserted groove (101) extending along a longitudinal direction, a pair of latching arms (11) extending forwards from two opposite ends of the main body and a pair of sidewalls (12) respectively positioned outside of the latching arms, each sidewall defines a slot (121) therein. The latching members are assembled on the latching arms, each latching member is being attached to an outer side of a corresponding latching arm and defines a blocking portion (35) extending into the slot.

Abstract: An edge connector assembly includes a PCB defining a first face, a second face opposite to the first face thereof and a notch therein, a daughter board defining a front mating portion and a rear retaining portion and an edge connector mounted in the notch of the PCB. The connector includes an insulating housing defining a longitudinal slot for receiving the front mating portion of the daughter board and a mounting face thereof to abut against the first face of the PCB, a plurality of contacts defining contacting portions extending into the slot. The daughter board is inserted into slot from the second face of the PCB in a slant direction and then pivots about the front mating portion and is retained in the notch.

Abstract: A latching device (1) for retaining two daughter printed circuit boards (6), includes a fixing member (2) of one piece and a pair of metallic latching members (3) secured to the fixing member. The fixing member includes an elongated main body (20), a pair of supporting portions (21) extending from each side of the main body to support one daughter printed circuit board. The latching members cooperate with the supporting portions to latch and unlatch the daughter printed circuit boards.
