Abstract
Abstract The card edge connector (1) has frames (2) facing each other. Partition (14) is secured by means of lances (60) retained by protrusions made in the main body (16). By inserting partition (14), one can obtain cavities (28) formed on both sides of the partition for accommodating thin cards. By removing partition (14) one can obtain a single cavity (29), thus cavities (28) can be combined to accommodate thick cards.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
127 words
A card edge connector for use with an electrical circuit, comprising: a main body portion having two frame portions which are joined together to form a main cavity in the main body, said main body portion has first and second operating members joined to a side thereof and joined to an ejecting device for operatively ejecting a pair of cards from the main cavity; said main body further including electrical contacts at one end of the main cavity for connection to said electrical circuit, and an opening at the other end of the main cavity for receiving said cards; and wherein a removable partition is provided between the frame portions thereby forming two smaller cavities for receiving said cards, the partition being removably inserted through said opening.
Claim 2
Dependent Claim
127 words
A card edge connector for use with an electrical circuit, comprising: a main body portion having two frame portions which are joined together to form a main cavity in the main body, said main body portion has first and second operating members joined to a side thereof and joined to an ejecting device for operatively ejecting a pair of cards from the main cavity; said main body further including electrical contacts at one end of the main cavity for connection to said electrical circuit, and an opening at the other end of the main cavity for receiving said cards; and wherein a removable partition is provided between the frame portions thereby forming two smaller cavities for receiving said cards, the partition being removably inserted through said opening.
Claim 3
Dependent Claim
21 words
The card edge connector of claim 1, wherein removable fasteners are provided for mounting the card edge connector to a surface.
Claim 4
Dependent Claim
29 words

Claim 5
Dependent Claim
26 words
The card edge connector of claim 1, wherein a pair of locking lances are provided on the partition for locking the partition to the main body.
Claim 6
Dependent Claim
23 words
The card edge connector of claim 1, wherein the electrical contacts comprise two rows of contacts, one row for each of said cards.
Claim 7
Dependent Claim
21 words
The card edge connector of claim 1, wherein inner surfaces of the frames include lugs for retaining the cards in place.
Claim 8
Dependent Claim
19 words
The card edge connector of claim 1, wherein the operating members are located at opposite sides of the cavity.
Claim 9
Dependent Claim
35 words
The card edge connector of claim 1, wherein each of the cards has a thickness, and the thickness of one card is the same as the thickness of the other of said pair of cards.
Claim 10
Dependent Claim
35 words
The card edge connector of claim 1, wherein each of the cards has a thickness, and the thickness of one card is the greater than the thickness of the other of said pair of cards.
Claim 11
Dependent Claim
107 words
A memory card connector for electrical connection to memory cards, comprising: a main body member including frame members mounted one on top of the other forming a main cavity in said main body member, said frame members having sides with turned-in ends; operating members slidably mounted along respective sides of said frame members; ejecting devices mounted on respective frame members and operatively connected to respective frame members for ejecting one or a pair of memory cards from said main body member; and fasteners removably mounted onto said frame members adjacent front ends and rear ends thereof thereby maintaining said frame members in position forming said main cavity.
Claim 12
Dependent Claim
107 words
A memory card connector for electrical connection to memory cards, comprising: a main body member including frame members mounted one on top of the other forming a main cavity in said main body member, said frame members having sides with turned-in ends; operating members slidably mounted along respective sides of said frame members; ejecting devices mounted on respective frame members and operatively connected to respective frame members for ejecting one or a pair of memory cards from said main body member; and fasteners removably mounted onto said frame members adjacent front ends and rear ends thereof thereby maintaining said frame members in position forming said main cavity.
Claim 13
Dependent Claim
18 words

Claim 14
Dependent Claim
35 words
A memoory card connector as claimed in claim 11, wherein tabs are cut out form said frame members thereby forming mounting members for mounting said operating members onto the respective sides of the frame members.
Claim 15
Dependent Claim
23 words
A memory card connector as claimed in claim 12, wherein said operating members are mounted along opposite sides of said main body member.
Claim 16
Dependent Claim
30 words
A memory card connector as claimed in claim 10, wherein a removable partition is mounted between the turned-in ends of said sides thereby forming two cavities of said main cavity.
Claim 17
Dependent Claim
32 words
A memory card connector as claimed in claim 10, wherein the front end removable fasteners have flat shoulders and stiffening ribs fitted into depressions located in the sides of said frame members.
Claim 18
Dependent Claim
50 words
A memory card connector as claimed in claim 10, wherein the rear end removable fasteners are L-shaped including a main section having bent-in tabs at edges thereof which fit into slits in said main body member and a protrusion fitting between said frame members keeping them at a predetermined distance.
