Abstract
Abstract The invention relates to a card edge connector (10) with a housing (12) and electrical contacts (14). The electrical contacts (14) are spaced from adjacent contacts (14) at a center-to-center pitch of 0.64 mm (0.025 inch). The contacts (14) each have a middle section (34) that is interference-fit in a contact receiving channel (18) of the housing (12). The middle sections (34) each have a general ring shape with a center electromagnetic reduction aperture. The ring shape forms a structural truss to retain structural rigidity of the middle section (34) to enable the interference fit to be made and, the center electromagnetic reduction aperture reduces capacitance between the closely spaced adjacent contacts (14).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
105 words
A card edge connector (10) comprising: a housing (12) having a card edge receiving area (16) and two rows of contact receiving channels (18) on opposite sides of the card edge receiving area (16); and electrical contacts (14) connected to the housing (12) in the contact receiving channels (18), each contact (14) having a top spring arm (30), a bottom solder tail (32), and a middle section (34) therebetween, each of the middle sections (34) having a general ring shape with a center aperture (46) and two opposite sides making an interference fit with the housing (12) in one of the contact receiving channels (18).
Claim 2
Dependent Claim
18 words
A connector as in claim 1, wherein the electrical contacts (14) include at least two types of contacts.
Claim 3
Dependent Claim
28 words
A connector as in claim 1, wherein the top spring arms (30) each have an enlarged section at their connections with the middle sections (34) for increased strength.
Claim 4
Dependent Claim
19 words
A connector as in claim 1, wherein the top spring arms (30) each have a coined contact surface (36).
Claim 5
Dependent Claim
33 words
A connector as in claim 1, wherein the contacts in each row of contact receiving channels (18) are spaced from adjacent contacts (14) at a center-to-center spacing of about 0.64 mm (0.025 inch).
Claim 6
Dependent Claim
24 words
A connector as in claim 1, wherein the solder tails (32) extend from a bottom (24) of the housing (12) in a staggered pattern.
Claim 7
Dependent Claim
143 words
In a card edge connector (10) having a housing (12) and electrical contacts (14), each of the contacts (14) having a cantilevered spring arm (30) for contacting an edge of a daughter printed circuit board, a solder tail (32) for contacting a mother printed circuit board, and a middle section (34) between the spring arm (30) and solder tail (32), the middle section (34) forming an interference fit with the housing (12), the improvement comprising: the middle sections (34) of the contacts (14) each having a relatively large electromagnetic reduction aperture in their centers to form a general ring shape, wherein the general ring shape allows the middle section (34) to have sufficient structural rigidity to form the interference fit with the housing (12) and, also reduces the amount of material in the middle section (34) to reduce capacitance between adjacent contacts (14).
Claim 8
Dependent Claim
25 words
A connector as in claim 7, wherein the contacts (14) are spaced from adjacent contacts at a center-to-center spacing of about 0.64 mm (0.025 inch).
Claim 9
Dependent Claim
24 words
A connector as in claim 7, wherein the solder tails (32) extend from a bottom (24) of the housing (12) in a staggered pattern.
Claim 10
Dependent Claim
24 words
A connector as in claim 7, wherein the contacts (14) are comprised of flat sheet metal that is cut to form the contacts (14).
Claim 11
Dependent Claim
16 words
A connector as in claim 10, wherein the spring arms (30) have a coined contact area.
Claim 12
Dependent Claim
82 words
A card edge connector comprising: a housing (12) having a card edge receiving area (16); and electrical contacts (14) connected to the housing (12), the contacts (14) having a middle section (34) with two opposite side walls forming an interference fit with the housing (12) and an electromagnetic reduction aperture between the two walls, the middle section (34) having a general structural truss shape to retain structural rigidity between the two walls, but which also allows the aperture to be substantially large.
Claim 13
Dependent Claim
16 words
A connector as in claim 12, wherein the structural truss shape comprises a general ring shape.
Claim 14
Dependent Claim
24 words
A connector as in claim 12, wherein the contacts (14) are comprised of flat sheet metal that is cut to form the contacts (14).
Claim 15
Dependent Claim
20 words
A connector as in claim 14, wherein the contacts (14) each have a spring arm with a coined contact area.
Claim 16
Dependent Claim
26 words
A connector as in claim 12, wherein the contacts (14) are spaced from adjacent contacts (14) at a center-to-center spacing of about 0.64 mm (0.025 inch).
