Abstract

Abstract The memory cards (10) described herein have printed circuit boards (30) comprising a frame (20) for housing the printed circuit board (30) in the memory cards (10), covers (70, 80) in sealing engagement with the frame (20) for securing the printed circuit board (30) to the frame (20), and tabs (110) integrally attached to the covers (70,80) for grounding the printed circuit boards (30) to the memory cards (10). The memory cards (10) described herein provide efficient grounding of printed circuit boards, thereby allowing the memory cards to operate with good signal characteristics. The cards (10) further comprise connectors (40) adapted to mate with a printed circuit board for interfacing data from the printed circuit board (30) to an outside environment which will utilize the memory card, lateral receiving pockets (50) on a frame (2) in the memory card for locking the connector to the frame and providing structural integrity to the memory cards, and interlocking tabs (60) integrally disposed on the connector and further adapted to mechanically interface with the lateral receiving pockets for securely locking the connector to the frame and providing structural integrity to the memory card when the connector is mounted to the printed circuit board and mated to the frame.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 130 words
A memory card holder (10) including an electrical connector (40) and a frame (20) for receiving a memory card (30) containing electrical circuit traces and ground traces thereon, said frame (20) including a pair of side rails, and a pair of hermaphroditic, electrically conductive cover members (70,80) adapted to engage said side rails, characterized in that: each said cover member (70,80) includes an integral angularly disposed, inwardly directed grounding tab (110) for compressive contact with a complementary ground trace on said memory card (30), and plural peripheral tabs (90,110) in contact with and in sealing engagement with said frame side rails; and wherein interlocking members (50,60) are provided on the connector (40) and the frame (20) for joining the connector (40) to the frame (20) and the memory card (30).
Claim 2
Dependent Claim 23 words
The memory card holder (10) according to claim 1, wherein the frame (20) includes plural transverse members extending between said frame side rails.
Claim 3
Dependent Claim 42 words
The memory card holder (10) according to claims 1 or 2, wherein contacts (120) are attached to the two side rails for grounding the memory card (30) in an electronic device when the memory card (30) is mated to the electronic device.
Claim 4
Dependent Claim 56 words
The memory card holder (10) according to any of claims 1-3, wherein certain of said tabs (90,150) are press-fit tabs (90) attached to the sides of the cover (70,80) and protruding therefrom for mating with a plurality of reciprocal press-fit openings (100) on said side rails to tightly seal the cover (70,80) to the frame (20).
Claim 5
Dependent Claim 38 words
The memory card holder (10) according to any of claims 1-4, further including a receptacle (90) on one end of said covers (70,80) for housing a connector (140) for mating the memory card (30) to an electronic component.
Claim 6
Dependent Claim 27 words
The memory card holder (10) according to any preceding claim, wherein the interlocking members comprise a jigsaw-shaped tab (60) for disposition between a pair of ledges (50A,50B).
