Burn in socket for flat pack semiconductor package

An electrical connector for interconnecting flatpack semiconductor packages thereto, the package being receivable in a carrier having a plurality of channels therein for receiving the plurality of flatpack leads, the connector comprising:

• an insulative housing means having an upper package receiving face and a lower mounting face, the housing means having a plurality of channels extending into the package receiving face in communication with apertures which extend to the lower mounting face;
• a plurality of electrical terminals positioned within the channels, the terminals having looped portions which are disposed within the channels with portions extending above the package receiving surface to form radiused contact portions;
• and
• two latch members, one latch member disposed at each end of the housing means, each being rotatable on a horizontal axis about the ends thereof and outwardly of the housing means, the horizontal axes about which the latch members rotate are laterally inward of the latching surfaces, the outward rotation of the latch members thereby causing a downward motion of the latching surfaces, the latch members being biased inwardly in a normally closed position, the latch members having downwardly and inwardly facing cam surfaces on an inside surface thereof being profiled for mating interference with the carrier, where downward movement of the carrier rotates the latches open to receive the carrier, the latches springing shut to a position where the downwardly facing shoulders overlie the carrier, whereby
• when the carrier and package are inserted into the housing the latches open outwardly and the contact between the package leads and the terminal contact point causes a rotation of the looped portions, the contact points moving laterally inward against the package leads thereby wiping the package leads, and when the carrier reaches a vertical position within the housing where the latching surfaces clear the edges of the carrier, the latches bias closed, and the carrier moves vertically upward to a new position against the latching surfaces, the contact point backwiping the package leads to reside in a wiped area.

An electrical connector for interconnecting a semiconductor package and a carrier thereto, the connector comprising:

• an insulative housing means having a plurality of channels located therein, the housing having latch supporting means located at each end thereof, the latch supporting means including a U-shaped slot opening downwardly, the housing further including an outer surface which is disposed above the U-shaped slot;
• a plurality of terminals located within the housing;
• a latch assembly including a latch member having an aperture extending therethrough, the assembly further including a torsion spring means, a pin and fastener means at the ends of the pin, whereby
• the latch assembly can be preassembled with the torsion spring means slidably placed over the pin and the fastener means preassembled to ends of the pin and the latch assembly can be slidably received into the housing with the pin residing in the U-shaped slot, with further inward movement of the fastener means securing the latch assembly to the housing.
