Abstract
Abstract A card connector has a dielectric support (12) and card-engaging contacts (14), wherein the contacts can be easily mounted on the support and are stably held in position thereon. Each strip-shaped contact has a contacting front end portion (44) that projects above the top face of the support, a central portion (42) that extends longitudinally rearward from the front portion and which is securely mounted on the support, and a rear end (46) for connecting to a circuit board. The central portion has a rear part with a strip-shaped middle section (124) extending in a longitudinal direction, and first and second feet (52, 58) lying on laterally opposite sides of the middle section. The support has a longitudinally extending groove (28) that receives the contact central portion, and has foot-holding slots (32, 34) on laterally opposite sides of the groove. Each slot has top and bottom slot walls (36, 40) that engage a corresponding one of the feet, to fix the location of the rear part of the central portion, and to prevent pivoting of the rear part about a longitudinal axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
310 words
An electrical card connector comprising: a support (12) molded of insulating material and having an upper wall (130) with an upper face (20), and a plurality of largely strip-shaped sheet metal contacts (14) with each contact being elongated and extending in a longitudinal direction (M); each of said contacts having a contacting front end portion (44) with a pad-engaging part (110) projecting upwardly above the support upper face, a longitudinally elongated central portion (42) for mounting the contact (14) to the support (12) with the central portion having laterally spaced first and second sides, and a termination rear end (46) for connecting the contact to processing circuitry; said support having a groove (28) and a pair of slots (32, 34) on laterally opposite sides of said groove; said central portion (42) of each contact (14) includes a strip-shaped middle section (124) lying in said groove, and a catching foot (52) lying on a first lateral side of said middle section for fixing the contact (14) to the support (12), and with said catching foot received in a first (32) of said slots; each contact blade (14) includes a lateral stabilizing foot (58) which lies on a second lateral side of said middle section and which is trapped in a second (34) of said slots; each of said largely strip-shaped sheet metal contacts is formed of a sheet of metal that originally lay in a plane (P) and had a predetermined thickness (T), and each largely strip-shaped sheet metal contacts has bends about axes (A1, A2) that extend parallel to the plane (P) of said sheet and is devoid of bends about axes (B) that are normal to said sheet, with an average width of gaps (111, 113) between said middle section and each of said feet (52, 58) being no more than an average width of said middle section (124).

An electrical card connector comprising: a support (12) molded of insulating material and having an upper wall (130) with an upper face (20), and a plurality of largely strip-shaped sheet metal contacts (14) with each contact being elongated and extending in a longitudinal direction (M); each of said contacts having a contacting front end portion (44) with a pad-engaging part (110) projecting upwardly above the support upper face, a longitudinally elongated central portion (42) for mounting the contact (14) to the support (12) with the central portion having laterally spaced first and second sides, and a termination rear end (46) for connecting the contact to processing circuitry; said support having a groove (28) and a pair of slots (32, 34) on laterally opposite sides of said groove; said central portion (42) of each contact (14) includes a strip-shaped middle section (124) lying in said groove, and a catching foot (52) lying on a first lateral side of said middle section for fixing the contact (14) to the support (12), and with said catching foot received in a first (32) of said slots; each contact blade (14) includes a lateral stabilizing foot (58) which lies on a second lateral side of said middle section and which is trapped in a second (34) of said slots; each of said largely strip-shaped sheet metal contacts is formed of a sheet of metal that originally lay in a plane (P) and had a predetermined thickness (T), and each largely strip-shaped sheet metal contacts has bends about axes (A1, A2) that extend parallel to the plane (P) of said sheet and is devoid of bends about axes (B) that are normal to said sheet, with an average width of gaps (111, 113) between said middle section and each of said feet (52, 58) being no more than an average width of said middle section (124).
Claim 3
Dependent Claim
72 words
The electrical connector described in claim 1 wherein: said catching foot (52) and said stabilizing foot (58) are each joined to a corresponding one of said lateral sides of said middle section by a cross-piece (60, 62) of smaller longitudinal length than said feet, with said cross-pieces (60, 62) being aligned in a lateral direction and each being longer in said longitudinal direction (M) than its width in said lateral direction (L).
Claim 4
Dependent Claim
63 words
The connector described in claim 1 wherein: said support has longitudinally-spaced vertical projections (114, 116) forming top and bottom walls of a first of said slots, said vertical projections including upward projections projecting upwardly from said top wall and downward projections projecting downwardly from said bottom wall, with said upward and downward projections being staggered in a longitudinal direction along said first slot.
Claim 5
Dependent Claim
43 words
The electrical connector described in claim 1, wherein: said groove (28) has an upper end forming a channel (69) which is wide enough to receive the pad-engaging part (110) of said front end portion during forward insertion of the contact into said support.
Claim 6
Dependent Claim
44 words
The electrical connector described in claim 4, wherein: said contact central portion (42) has a widened front end (68) whose transverse width (L1) is greater than the width (L3) of said channel but that is less than the width (L2) of the groove (28).
