Abstract: A mirror swing actuator assembly for an optical path folding element (OPFE) for compact folding camera modules comprises an exit aperture for outputting folded light rays, and an incoming aperture for receiving incoming light rays, wherein a distance between a top lens of a lens actuator and an end of the optical path folding element is minimized by configuring the second aperture and/or a support assembly of the optical path folding element to receive, within the mirror swing actuator assembly, an end portion of the optical actuator/lens assembly that comprises the top lens.

Abstract: A lens position adjustment device includes a lens holder, a first shape memory alloy (SMA) wire and a second SMA wire. The lens holder holds a lens. The first SMA wire is configured to move the lens holder in a first direction along an optical axis of lens. The second SMA wire is configured to move the lens holder in a second direction along the optical axis. The second direction is opposite to the first direction. The lens holder is moved in the first or second direction along the optical axis through energizing the first SMA wire and the second SMA wire and controlling a force that moves the lens holder.

Abstract: An electrical connector includes an insulative housing and a shielding plate attached to the housing. The housing includes a pair of locking arms extending from opposite ends thereof substantially along a direction along which the shielding plate is attached to the housing. The shielding plate includes opposite side portions engaging with the locking arms of the housing. Each locking arm of the housing has a protrusion. Each side portion of the shielding plate defines an opening engagingly receiving the protrusion of the locking arm therein.

Abstract: A retainer device for fixing a heat sink (2) on a chip (4) includes a mounting frame (31), a base plate (33) and a mounting lever (32). The heat sink has a number of upwardly extending cooling fins (21) and a pair of securing outwardly extending flanges (23). The mounting frame includes a pair of retaining plates (312) for pressing against the securing flanges and a pair of spring plates (311) connecting the retaining plates. The retaining plate defines a clip (318) for engaging with the heat sink and a latch 317 on each end thereof. The base plate defines four receiving projections (331), each of which defines a notch (332) for receiving the latch. The mouning lever defines a base pole (321) received between the cooling fins. The base pole defines at least one protrusion (323) for pressing against the spring plates and the securing flanges.

Abstract: An electrical connector (1) includes an insulative housing (2) and a number of conductive contacts (3). The insulative housing defines a number of receiving passageways (20) for receiving the conductive contacts. The receiving passageways each comprise a pair of opposite side walls (21) and an upper wall (22) between the side walls. Each side wall defines a mounting channel (23). The conductive contact includes a retaining portion (31), a mating portion (33) extending forwardly from the retaining portion and a tail portion (32) extending rearwardly from the retaining portion. The retaining portion and the mating portion are both received in the receiving passageway. The mounting portion forms a pair of opposite mounting shoulders (34) received in the mounting channels and a number of barbs (37) for engaging with the side walls. The contact forms a number of projections (35) for interference fitting with the upper wall of the receiving passageway.

Abstract: An electrical connector includes an insulative housing (30) and a plurality of contacts (10). The housing has a plurality of cavities (36) arranged in two vertical stacks (54, 56), each stack being separated by thin walls (34) of the housing. Each contact has a main body (11), a contact portion (12) for mating with a mating connector, and a mounting member (15) extending perpendicularly from the main body. The mounting member protrudes from a bottom surface (46) of the housing. A plate-like support finger (18) extends obliquely from the main body. The support finger has a suspending end (19) parallel to the main body and extending toward the mounting member. The suspending end bears against a lower wall of the corresponding cavity, thereby preventing the main body from moving downwardly relative to the contact.

Abstract: A heat sink assembly for use with an electronic IC chip (4) includes a socket (30), a heat sink (2), a pair of mounting clips (32) and a pair of retention modules (31). The heat sink abuts against the chip and has a plurality of cooling fins (21) extending upwardly from a base (20) and a pair of securing flanges (22) extending outwardly from the base. Each retention module defines a protrusion (313) on a first sidewall (311) and a latch (314) on a second sidewall (312). Each mounting clip forms a base member (320) defining two apertures (327) for receiving the protrusions. An arm (321) with a notch (325) defined on a free end thereof is formed at either lateral end of the base member for engaging with the latches. A retaining clip (322) extends downwardly and inwardly from the mounting clip for pressing against the securing flange.
