Abstract
Abstract The expansion card is inserted into a narrow slot through the outside cover of the subscribers terminal and is guided by a carrier into the external connector. A protective casing on the card includes a pivotable door which permits the card to maintain a slim profile. The door is opened during the insertion process into the external connector by a pair of tongs positioned at an inclined angle on the carrier to expose the terminal end of the expanding card.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
133 words
A plug in expansion card for a subscriber terminal, comprising: a printed circuit (PC) card for mounting electronic components operative with the subscriber terminal, the PC card including a row of finger edge connection terminals; a casing for housing said PC card, said casing having a top surface, a bottom surface, and an upraised grip; a pivotable protective door having hinges affixed on the inside of said casing, said protective door being operative to a closed position adjacent to said edge connection terminals to protect said edge connection terminals and an open position revealing said edge connection terminals, said protective door being flush with said casing bottom surface when in said closed position; said casing top surface being inclined for draining spilled fluids; and a fluid draining trough positioned adjacent said upraised grip.
Claim 2
Dependent Claim
133 words
A plug in expansion card for a subscriber terminal, comprising: a printed circuit (PC) card for mounting electronic components operative with the subscriber terminal, the PC card including a row of finger edge connection terminals; a casing for housing said PC card, said casing having a top surface, a bottom surface, and an upraised grip; a pivotable protective door having hinges affixed on the inside of said casing, said protective door being operative to a closed position adjacent to said edge connection terminals to protect said edge connection terminals and an open position revealing said edge connection terminals, said protective door being flush with said casing bottom surface when in said closed position; said casing top surface being inclined for draining spilled fluids; and a fluid draining trough positioned adjacent said upraised grip.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
29 words
The plug in expansion card of claim 1, wherein said protective door is operative to flip downwardly relative to said casing bottom surface to reveal said edge connection terminals.
Claim 5
Dependent Claim
46 words
The plug in expansion card of claim 3, wherein said PC card has a top row of edge connection terminals and bottom row of edge connection terminals, and wherein said protective door is operative to flip downwardly to reveal said bottom row of edge connection terminals.
Claim 6
Dependent Claim
19 words
The plug in expansion card of claim 1, wherein said protective door is spring biased into said closed position.
Claim 7
Dependent Claim
34 words
The plug in expansion card of claim 5, wherein said protective door is operative to return to said closed position when the expansion card is removed from an insertion slot in the subscriber terminal.
Claim 8
Dependent Claim
34 words
The plug in expansion card of claim 1, wherein said protective door is operative to pivot to said open position when the expansion card is inserted into an insertion slot in the subscriber terminal.
Claim 9
Dependent Claim
49 words
The plug in expansion card of claim 7, wherein said protective door includes an inclined leading edge for engaging with components in the insertion slot in the subscriber terminal and urging said protective door downwardly into said open position as the expansion card is inserted into the insertion slot.
Claim 10
Dependent Claim
35 words
The plug in expansion card of claim 1, wherein said inclined casing top surface comprises two top surfaces that meet in a peak running along the length of the expansion card to channel liquids away.
Claim 11
Dependent Claim
26 words
