A foldable retainer device includes a pair of clamping members pivotably connected to distal ends of an elongate base frame, and a folding mechanism for retaining the pair of clamping members either perpendicular or parallel to the base frame.

Foldable retainer device

A conductive contact for an electrical connector is disclosed. The conductive contact comprises a lower inserting section for inserting into an external circuit board, an upper contacting section for engaging a mating lead pin of a chip, a middle fixing section for fixing onto a cooperating housing for an electrical connector, and anti-wicking means for prevention of wicking during wave soldering procedure. The anti-wicking means can be an inverted V-shaped groove formed on the fixing section or a horizontal plate stamped from the fixing section. The conductive contact can be formed by stamping and bending.

Anti-wicking conductive contact for an electrical connector

A ZIF PGA socket (20) includes a base (22) having a plurality of passageways (24) extending vertically therethrough for receiving a corresponding number of contacts (26) therein, and a cover (28) having a corresponding number of holes (30) extending therethrough in alignment with the corresponding passageways (24) in the base (22) for allowing a corresponding number of pins extending from the PGA component. A lever (44) includes a cam shaft (48) embedded within a channel (50) formed adjacent the rear region of the socket (20) wherein cover (28) includes a retention device (54) and the base includes a restriction plane (64) to cooperate with the retention device (54) of the cover (28), and both of the retention device (54) and the restriction plane (64) are disposed adjacent the cam shaft (48) for efficiently fastening the cover (28) and the base (22) together to resist the larger resistance force occurring thereabout during the socket (20) in a closed state.

Retention mechanism for self-securement of ZIF PGA socket

A ZIF PGA socket (20) includes a base (22) and cover (24) slidably relatively moveable thereto, and a lever (40) sandwiched between the base (22) and the cover (24) wherein the lever (40) includes a handle (42) exposed and accessible in an exterior and a cam shaft (44) embedded within an upper half channel (30) formed in the cover (24) and a lower half channel (32) formed in the base (22). The cam shaft (44) includes a projection (50) integrally radially extending therefrom for engagement with an engagement surface (56) formed within an opening (54) in the base (22) whereby the lever (40) can be substantially stopped in a vertical position for allowing the socket (20) in an open status to load a PGA thereto in a ZIF manner. The handle (42) further includes a rib (60) formed proximate the front end thereof for engagement with a facing downward abutment surface (62) formed on the base (22).

Stopper for use with ZIF PGA socket

An electrical socket (10) includes an insulative housing (12) with cavities (14) extending vertically therethrough and a plurality of contacts (30) retained in the cavities (14), respectively. An engagement bar (22) is positioned proximate the upper open end of each cavity (14) so that when the contact is assembled in each corresponding cavity (14), the front portions of the spring arms (40) of each contact (30) can move along a guiding pin (62), which is inserted into the cavity (14) from the top open end temporally only for the sake of assembling of the contacts (30) within the socket (10), and be deflected outwardly so that the tips (44') of the spring arms (40) of the contact (30) can pass the engagement bar (22) and be positioned by the sides of the engagement bar (22). Therefore, the tips (44') of the spring arms (40) of the contact (30) can abut against the opposite sides of the engagement bar (22) when the guiding pin (62) is removed from the socket (10), and a larger space is formed between the contact sections (42) of the spring arms (40) of the contact (30) for easy and low insertion force of the pins downward extending from the PGA component.

LIF PGA socket and contact therein and method making the same

A circuit board latching device (40, 41) for use with an insulative connector housing (31) includes a retaining wall (82) and a circuit board support post (52) in which the board support post (52) is positioned opposite the retaining wall (82). The latching device (40, 41) of the present invention comprises a main body portion (56) and a mounting mechanism for mounting the main body portion to the housing (31) between the retaining wall (82) and the board support post (52). Furthermore, a latch lug (71) extends from the main body portion (56) which includes a cam surface (72) which is inclined relative to the latch lug (71), and a lock surface (73) which is substantially perpendicular to the main body portion (56). Moreover, the latching device (40, 41) includes a resilient stress reducing arm (79) projecting angularly away from the main body portion (56) toward the retaining wall (82). In one aspect, the mounting mechanism comprises a mounting platform (94) which includes a plate (106) extending from the main body portion (56). A first finger (95) extends substantially downward from one end of the plate (106) while a second finger (96) extends substantially downward from the opposite end of the plate (106) which mountingly engage the housing (31). In another aspect of the present invention, the mounting mechanism comprises an upstanding sleeve (59) mounting member extending from the main body portion (56).

Electrical connector with improved latch mechanism

An electrical connector (10) with mounting means (5) for securement to a printed circuit board (7) comprises an elongated insulative housing (1) having embedded therein and extending therethrough a plurality of contacts (3) the tails (31) of which are bent to be parallel with the board (7). A mounting means (5) positioned at each end of the housing (1) has an L-shaped body (51) including a vertical plate (512) and a horizontal plate (511) which is coplanar with a bottom surface (13) of the housing (1). The mounting means (5) further comprises a U-shaped body (52) vertical to the L-shaped body (51), a portion of which is received within a slot (6) in the housing (1) and has a projecting tab (53) abutting against the inner portion of the slot (6) to fasten the mounting means (5) to the housing (1).

Connector with mounting means for SMT

A stackable memory card connector assembly (20) for use with multiple memory cards (15, 15') includes a first memory card connector (22) which comprises a side guide arm (32), a second side guide arm (32a) and a housing (24) interconnecting the first and second side guide arms (32, 32a). Further, a top guide (34) extends between the respective first and second side guide arms (32, 32a). The housing (24) defines a plurality of passageways (30, 31) in which a plurality of conductive members (54, 55) are dimensioned to be positioned therethrough. Moreover, respective first and second bottom alignment mechanisms are (56, 56a) disposed on a bottom surface of the respective first and second side guide arms (32, 32a). Similarly, first and second top alignment mechanisms (57, 57a) are disposed on a top surface of the respective first and second side guide arms (32, 32a) opposite the respective first and second bottom alignment mechanisms (56, 56a). Thus, when a second similarly dimensioned memory card connector (22') is stacked above the first memory card connector (22) in an aligned stackable fashion, the respective first and second bottom alignment mechanisms (56', 56a') of the second connector (22') engages with the respective first and second top alignment mechanisms (57, 57a) of the first memory card connector (22). Accordingly, the space occupied by the stacked memory card connector assembly (20) is reduced by providing a single common wall (34) between the stacked connectors (22, 22'), thereby reducing the overall height.
