Abstract: A PC cartridge having enhanced front connecting structure is disclosed. Two folded hooks with n-shaped structure are on the same side of the front connector and at two front corners of the upper shell. The folded hook defines a small height and has a rearward opening. Further, first and second flanges are located on the same side of the front connector and at the front ends of the packing rubbers located on the bottom shell. Especially, first and second flanges are parts extended from the packing rubbers, whereby retaining slots are formed between upper and bottom shells. Both the second flanges comprise a third flange projected forward. The folded hooks conform to the third flange and extend into the retaining slots so as to engage the upper shell with the bottom shell.

Abstract: The invention herein relates to a removable casing for memory card includes: an upper cover, a casing, a frontal cover and a lower cover wherein the casing is devised with a linkage terminal to be in contact with a memory card, the front of the casing is to receive the frontal cover while on either side of the casing extends a rod. The top and the bottom of the rod are each fitted with a plurality of notches, while on either side of the upper cover is at least one “U shape” catch and on either side of the lower cover is at least one “Inverse L shape” catch. The catches are to correspond to the notches for a match interlocking. The inside edges of rods are connected to a press board to exert pressure onto the linkage terminals to enhance the perfect evenness and overall steadiness of the terminals.

Abstract: An interface plastic housing assembly for memory cards includes a plastic housing in shape of a planiform rectangular body, a plurality of terminals that are disposed in the plastic housing and have connection legs adhered to a circuit board of a memory card. The characteristics thereof are that a supporting arm is provided at the two sides of the plastic housing, respectively, and at the bottom surface of the supporting arms is provided with one or more protruding pillars, respectively. In accordance with the above structure, the protruding pillars at the two sides of the plastic housing are fitted into positioning holes disposed in advance at an apparatus or the circuit board, so as to ensure steady positioning between the circuit board and the plastic housing for surface adhesion thereof, thereby reducing the defective rate of the product.

Abstract: A PC cartridge is provided at two front corners of an upper shell with two folded hooks that define a predetermined small height and rearward openings, and at two front ends of two packing rubbers attached to two sides of a bottom shell of the PC cartridge with two retaining slots, each of which includes a forward projected flange portion. When the upper shell is closed onto the bottom shell, the folded hooks extend into the retaining slots to fitly engage with the flange portions and therefore be retained to the retaining slots. The engagement of the folded hooks with the flange portions of the retaining slots produces a vertical coupling stress, enabling the coupled upper and bottom shells of the PC cartridge to resist increased pull applied on them without easily becoming deformed.
