Abstract
Abstract An electrical contact (10) for insertion into an opening (31) in a housing wall comprises a substantially solid conductive member (20) having a radius smaller than the opening in the housing wall, a pair of substantially planar contact surfaces (18 & 22) on opposing ends of the conductive member, and at least one barb (14 or 16) on the entire periphery of the solid conductive member located between the planar contact surfaces, wherein the barb has a larger radius than the opening in the housing wall.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
158 words
An electronic device having electrical contacts for insertion into a housing wall of the electronic device, said electrical contact comprising: a substantially solid conductive member having a radius less than the opening in the housing wall; a pair of substantially planar contact surfaces disposed on opposing ends of the conductive member, said contact surfaces further comprising: an electrical connection means, including a flex circuit, and wherein at least one contact surface is mounted so as to be substantially flush with an outside surface of the housing wall; at least two barbs disposed concentrically about the periphery of the conductive member, and between said planar contact surfaces, wherein the barbs have a larger radius than the opening of the housing wall, said barbs wedging into the housing wall, providing an environmental seal; and a head region disposed about one of said substantially planar contact surfaces having a circumference larger than the contact, and the opening in said housing wall.
Claim 2
Dependent Claim
158 words
An electronic device having electrical contacts for insertion into a housing wall of the electronic device, said electrical contact comprising: a substantially solid conductive member having a radius less than the opening in the housing wall; a pair of substantially planar contact surfaces disposed on opposing ends of the conductive member, said contact surfaces further comprising: an electrical connection means, including a flex circuit, and wherein at least one contact surface is mounted so as to be substantially flush with an outside surface of the housing wall; at least two barbs disposed concentrically about the periphery of the conductive member, and between said planar contact surfaces, wherein the barbs have a larger radius than the opening of the housing wall, said barbs wedging into the housing wall, providing an environmental seal; and a head region disposed about one of said substantially planar contact surfaces having a circumference larger than the contact, and the opening in said housing wall.
Claim 3
Dependent Claim
22 words
An electronic device as in claim 1, wherein the head mounts in a recessed area on the inner portion of the housing.
