Abstract
Abstract An electrical connector 12 is provided for receiving a card edge into a card-receiving slot 13. A series of contacts 20 are disposed inside contact-receiving cavities 14 which are provided along the card-receiving slot 13. The contacts 20 have a cantilever arm 42, a tail section 40 and a contact section 48 which is lanced from the cantilever arm 42. The contact section 48 is profiled to have a contact point 50 located at a distance from the cantilever arm 42 near a free end 44.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
An electrical connector having a housing with a slot for receiving the edge of a printed circuit card, a series of contact cavities extending generally perpendicular to the slot, and a respective series of contacts disposed in the contact receiving cavities for establishing electrical connections to contact pads on the edge of the printed circuit card, the connector comprising: the series of contacts being loadable into the housing from a mating end, the contacts having a main body extending from the mating end to a mounting end, and a tail extending from the main body through the mounting end, to a printed circuit board and being securable to the housing at the mounting end proximate the printed circuit board, a contact portion being lanced from the main body proximate the mating end thereby leaving an opening in the main body, the contact portion having a free end and an attached end connected to the main body at an attachment point, and a contact point spaced apart from the main body, the free end extending adjacent to the opening, the main body having a coined section extending into the opening to prevent deflection of the free end therethrough.

Claim 3
Dependent Claim
21 words
The electrical connector as recited in claim 1 wherein the contact cavities each comprise a major projection and a minor projection.
Claim 4
Dependent Claim
43 words
The electrical connector as recited in claim 2 wherein the major projection further includes a contact retention surface proximate the mounting end, a pivot surface adjacent the contact retention surface and an overstress surface extending from the pivot surface toward the mating end.
Claim 5
Dependent Claim
29 words
The electrical connector as recited in claim 2 wherein the minor projection is located at a distance from the major projection to define a contact free end receiving area.
Claim 6
Dependent Claim
25 words
The electrical connector as recited in claim 1 wherein the contact point is disposed along the contact portion at a distance from the attachment point.
Claim 7
Dependent Claim
22 words
The electrical connector as recited in claim 5 wherein the free end is bent from the contact point toward the main body.
Claim 8
Dependent Claim
22 words
The electrical connector as recited in claim 1 wherein the contact portion is attached to the main body at two attachment points.
Claim 9
Dependent Claim
22 words
The electrical connector as recited in claim 7 wherein the contact point is disposed on the contact section between the attachment points.
