Four leaf receptacle contact

Claim 2

An electrical contact for electrical connection with a tab contact, comprising: a leaf spring in the form of unitary plate having a long spring arm with an outer contact member, and a short spring arm extending beside said long spring arm with inner contact member, said long spring arm and said short spring arm being freely movable relative to one another, said outer contact member having a contact surface of width about twice that of said contact surface of said inner contact member so as to extend across the inner contact member and is in axial alignment with said inner contact member so that said outer contact member initially engages a major surface of the tab contact during relative movement of the tab contact and the electrical contact, thereby cleaning said major surface and said inner contact member next engages the said cleaned major surface.

Claim 3

An electrical contact as claimed in claim 1, wherein said leaf spring includes opposed leaf springs linked together via a linking member.

Claim 4

An electrical contact as claimed in claim 1, wherein said outer and inner contact members are arcuate.

Claim 5

An electrical contact for electrical connection with a tab contact, comprising opposed leaf spring members formed from a suitable electrically-conductive metal sheet having spring characteristics, each said leaf spring member comprising (a) a long spring arm with an outer contact member having a width of dimension W, and (b) a short spring arm beside said long spring arm and freely movable relative thereto, and having an inner contact member having a width of a dimension of about W/2, whereby said outer contact member extends across the inner contact member and is in axial alignment with said inner contact member so that said outer contact member initially engages a major surface of the tab contact during relative movement of the tab contact and the electrical contact thereby cleaning said surface, and said inner contact member next engages said cleaned surface.

Claim 6

An electrical contact for electrical connection with a tab contact, comprising opposed leaf spring members formed from a suitable electrically-conductive metal sheet having spring characteristics, each said leaf spring member comprising (a) a long spring arm with an outer contact member having a width of dimension W, and (b) a short spring arm beside said long spring arm and freely movable relative thereto, and having an inner contact member having a width of a dimension of about W/2, whereby said outer contact member extends across the inner contact member and is in axial alignment with said inner contact member so that said outer contact member initially engages a major surface of the tab contact during relative movement of the tab contact and the electrical contact thereby cleaning said surface, and said inner contact member next engages said cleaned surface.

Claim 7

An electrical contact as claimed in claim 4, wherein said leaf spring includes opposed leaf springs linked together via a linking member.

Claim 8

An electrical contact as claimed in claim 4, wherein said long spring arm and said short spring arm are respectively opposed to one another.

Claim 9

An electrical contact as claimed in claim 4, wherein said outer and inner contact members are arcuate.

Claim 10

An electrical contact for electrical connection with a tab contact, comprising opposed leaf spring members linked together by a U-shaped member and formed from a suitable electrically-conductive metal sheet having spring characteristics, each said leaf spring member comprising (a) a long spring arm with an outer contact member having a width of dimension W, and (b) a short spring arm beside said long spring arm and freely movable relative thereto, and having an inner contact member having a width of a dimension of about W/2, (c) each said outer contact member extending across the adjacent inner contact member and in axial alignment therewith, whereby, during relative movement of said tab contact and said electrical contact, sequentially said tab contact initially engages said outer contact members to cause a cleaning of said tab contact prior to engagement and electrical contact with said inner contact members.

Claim 11

An electrical contact for electrical connection with a tab contact, comprising opposed leaf spring members linked together by a U-shaped member and formed from a suitable electrically-conductive metal sheet having spring characteristics, each said leaf spring member comprising (a) a long spring arm with an outer contact member having a width of dimension W, and (b) a short spring arm beside said long spring arm and freely movable relative thereto, and having an inner contact member having a width of a dimension of about W/2, (c) each said outer contact member extending across the adjacent inner contact member and in axial alignment therewith, whereby, during relative movement of said tab contact and said electrical contact, sequentially said tab contact initially engages said outer contact members to cause a cleaning of said tab contact prior to engagement and electrical contact with said inner contact members.

Claim 12

An electrical contact as claimed in claim 8, where said outer and inner contact members are arcuate to facilitate insertion of the tab contact therein.

Claim 13

An electrical connector for electrical connection with a complementary electrical connector, comprising: dielectric housing means having rows of contact-receiving passages in which electrical contacts are secured; a first row of electrical contacts defining ground contacts; a second row of electrical contacts defining signal contacts; a third row of electrical contacts defining signal contacts; electrical contact members provided by said electrical contacts; the contact members of said first to third rows of said electrical contacts are staggered such that said first row of contacts are spaced closer to the front of the housing means than the contact members of the second row of contacts which are spaced closer to the front of the housing means than the contact members of the third row of contacts so that the matable electrical contact means of the complementary electrical connector when mated with said electrical connector electrically connect with the electrical contact members of the first, second and third rows of electrical contacts in sequence with the ground connections being made first, the power connections being made second and the signal connections being made third.

Claim 14

An electrical connector for electrical connection with a complementary electrical connector, comprising: dielectric housing means having rows of contact-receiving passages in which electrical contacts are secured; a first row of electrical contacts defining ground contacts; a second row of electrical contacts defining signal contacts; a third row of electrical contacts defining signal contacts; electrical contact members provided by said electrical contacts; the contact members of said first to third rows of said electrical contacts are staggered such that said first row of contacts are spaced closer to the front of the housing means than the contact members of the second row of contacts which are spaced closer to the front of the housing means than the contact members of the third row of contacts so that the matable electrical contact means of the complementary electrical connector when mated with said electrical connector electrically connect with the electrical contact members of the first, second and third rows of electrical contacts in sequence with the ground connections being made first, the power connections being made second and the signal connections being made third.

Claim 15

An electrical connector as claimed in claim 10, wherein said electrical contacts each comprise receptacle contact members having opposed leaf spring members linked together by linking means and first spring arms and second spring arms, said first spring arms including outer contact members, said second spring arms including inner contact members.

Claim 16

An electrical connector as claimed in claim 11, wherein said inner and outer contact members are in axial alignment.

Claim 17

An electrical connector as claimed in claim 11, wherein said outer contact members are about twice the width of said inner contact members.

Claim 18

An electrical connector as claimed in claim 11, wherein said inner and outer contact members are arcuate.
