A photoelectric connector assembly includes a first lens member connecting with fiber cables and defining convex lenses opposite to fiber cables, a connector and a substrate embedded with waveguides. The connector defines a mating cavity running through a front face thereof and inserted with said first lens member. The connector includes terminals with contacting sections exposing to the mating cavity, a second lens members. The second lens member is located at back of the first lens member and defines first convex lenses at a front face thereof and second convex lenses at a rear face thereof. The first convex lenses are coupled with the convex lens of the first lens member. The substrate defines light ports at free ends of the waveguides. The substrate is seated with the connector and the light ports are coupled with the second convex lenses of the second lens member.

A burn-in socket for receiving an IC package comprises a socket body, a plurality of contacts mounted in the socket body and an actuator movably mounted upon the socket body. Each contact in the socket body includes a pair of clipping arms with tip portions at free ends thereof respectively. Solder balls attached to the bottom of the IC package are respectively clipped between the pair of the tip portions and thus the IC package should be brought into electrical contact with the contacts of the burn-in socket. The tip portion is plated with a Pd—Co layer for reducing the attachment of the Sn and preventing the impedance of the contacts to increase. Meanwhile, the IC package can be sucked up successfully without absorption from the contacts of the burn-in socket.

A photoelectric connector assembly includes a first and a second connector and a photoelectric signal conversion module. The first connector defines a mating cavity, first terminals including contacting sections exposing to the mating cavity and a first light transmission module including convex lenses at a front thereof exposing to the mating cavity and first light ports at a rear thereof The second connector includes an insulating seat and second terminals. The seat defines a rear mating end loading the second terminals and a receiving cavity opening upwards. The conversion module is inserted in the receiving cavity and includes second light ports coupled with the first light ports of the first light transmission module and conductive pads touching with the second terminal.

A test socket, adapted for connecting the semiconductor package and a printed circuit board comprises a base and a plurality of contacts received in the base. The base has a retaining board defining a plurality of first receiving holes and a positioning board defining a plurality of second receiving holes. The contacts has a contacting portion, an elastic portion and a retaining portion, the elastic portion is disposed between the retaining board and the positioning board and protruding rightward, and the contacting portion extends beyond the elastic portion and defines a acute angle with a horizontal line in a right hand before contacting with the semiconductor package to prevent the contacting portion from scratching with the left inner sidewall of the second receiving hole when pushed downward by the semiconductor package and rotating leftward.

A socket connector includes a socket body, a moving plate movably mounted upon the socket body, and an actuating mechanism. The actuating mechanism comprises a lid, a first operating lever, and a second operating lever. The first and second operating levers are disposed between the lid and moving plate with opposite tilted angles. The first operating lever has a cam section engaged with a bearing section formed on the moving plate so as to drive the moving plate to move in a substantially horizontal direction.

An burn-in socket used for connecting an IC package includes an base, a actuated device floatably assembled on said base, a frame retained on said base, a plurality of contacts received in said base and a switch member rotatable assembled on said base. Said actuated device includes a plurality of sustaining shafts with a plurality of rollers ringed thereon. Said switch member includes a plurality of rotating shafts retained on said base and a plurality of latching members engaged with said rotating shafts and rotating between an open position and a locking position. Said rollers of sustaining shafts moveable engaged with said latching member, which lowers the abrasion while the latching members are rotating between said open position and said locking position around said rotating shafts.
