Card connector assembly

Claim 2

A card connector assembly for connecting a memory device to a printed circuit board comprising: a shell assembly for accommodating the memory device including at least one shell compartment which encloses a substantial portion of the memory device; and a pin connector assembly including an insulating housing having a plurality of signal terminals mounted therein, each signal terminal including a connection pin adapted to be received in a corresponding receptacle of the memory device and a solder tail adapted to be soldered in a predetermined position to the printed circuit board, and a plurality of grounding terminals arranged generally parallel to the signal terminals, wherein said shell assembly is adapted to be assembled to said pin connector assembly by way of interengaging engagement members and corresponding slots on each side of the shell assembly and insulating housing of the connector assembly, respectively, whereby said shell assembly is assembled to said pin connector assembly after said solder tails of said signal terminals of said pin connector assembly are soldered to the printed circuit board.

Claim 3

A card connector assembly according to claim 1 wherein said shell assembly is a double-deck structure having an upper and lower shell compartment, and wherein the connection pins of said pin connector assembly are arranged in upper and lower rows to correspond to the upper and lower shell compartments of said shell assembly, thus permitting the upper and lower rows of the connection pins to be received in memory devices inserted into the upper and lower shell compartments.

Claim 4

A card connector assembly according to claim 2 wherein the insulating housing has upper and lower receiving slots in each side arm, and each of the upper and lower shell compartments includes an engagement piece integrally connected to each end which is received in a corresponding upper and lower receiving slots of the insulating housing upon assembly of the shell assembly to the pin connector assembly.

Claim 5

A card connector assembly according to claim 1 wherein said signal terminals of said pin connector assembly comprise first and second groups of terminals arranged in upper and lower levels, respectively, wherein each signal terminal of the first group includes a connection pin at one end and a solder tail at the other end, wherein the solder tail extends below the connection pin generally parallel to and away from the connection pin and toward the rear of the insulating housing, and each signal terminal of the second group includes a connection pin at one end and a solder tail at the other end, wherein the solder tail extends below the connection pin generally parallel to and toward the connection pin and toward the front of the housing.

Claim 6

A card connector assembly according to claim 4 wherein the insulating housing includes an alignment device to maintain the position of the solder tails of the second group of terminals during soldering.

Claim 7

A card connector assembly according to claim 4 wherein the insulating housing includes an alignment device to maintain the position of the solder tails of the first group of terminals during soldering.

Claim 8

A card connector assembly according claim 2 wherein the insulating housing has two side arms extending forward from opposite sides thereof, each including upper and lower longitudinal guide slots, and the upper and lower shell compartments of the shell assembly include upper and lower engagement nails which are received in said upper and lower longitudinal guide slots upon assembly of the shell assembly to the pin connector assembly.

Claim 9

A card connector assembly according to claim 7 wherein the guide slots include engagement projections formed therein to prevent the engagement nails from being removed from the longitudinal guide slots.

Claim 12

A method of assembling a card connector assembly according to claim 9 wherein the shell assembly further comprises fixing legs integrally connected to the shell compartments, the method further comprising the step of: fixing said shell assembly to the printed circuit board by soldering the legs to corresponding areas on the printed circuit board.

Claim 13

A card connector assembly for connecting two memory devices to a printed circuit board comprising: a double-deck shell assembly for accommodating the memory devices including an upper and lower shell compartment each of which includes a card-ejection mechanism composed of an ejection rod and an ejection lever; and a pin connector assembly including an insulating housing having a plurality of signal terminals mounted therein, each signal terminal including a connection pin arranged in upper and lower rows to correspond to the upper and lower shell compartments of said shell assembly and adapted to be received in a corresponding receptacle of a respective memory device and a solder tail adapted to be soldered to the printed circuit board, and a plurality of grounding terminals arranged generally parallel to the signal terminals, wherein said shell assembly is adapted to be assembled to said pin connector assembly by way of interengaging engagement members and corresponding slots on each side of the upper and lower shell compartments of the shell assembly and the insulating housing of the connector assembly, respectively.

Claim 14

A card connector assembly for connecting two memory devices to a printed circuit board comprising: a double-deck shell assembly for accommodating the memory devices including an upper and lower shell compartment each of which includes a card-ejection mechanism composed of an ejection rod and an ejection lever; and a pin connector assembly including an insulating housing having a plurality of signal terminals mounted therein, each signal terminal including a connection pin arranged in upper and lower rows to correspond to the upper and lower shell compartments of said shell assembly and adapted to be received in a corresponding receptacle of a respective memory device and a solder tail adapted to be soldered to the printed circuit board, and a plurality of grounding terminals arranged generally parallel to the signal terminals, wherein said shell assembly is adapted to be assembled to said pin connector assembly by way of interengaging engagement members and corresponding slots on each side of the upper and lower shell compartments of the shell assembly and the insulating housing of the connector assembly, respectively.
