Abstract

Abstract Right angle surface mount connector comprises a housing loaded with stamped and formed contacts, each having a mating portion, a solder tail, and a bend therebetween. The rear face of the connector has a rib with side-by-side channels having V-shaped floors therein, a portion of each solder tail being disposed resiliently against a respective floor so that the tails are self-centering but can move laterally. The contact is retained in the housing by a scalloped plate adjacent the mating portion, a cantilever arm between the plate and the bend assuring compliance of solder tails against the circuit board.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 201 words
A connector for mounting to a printed circuit board, comprising: a housing having a mating face, an opposed rear face, a mounting fsce perpendicular to the mating face and the rear face, and a plurality of contact receiving passages between the mating face and the rear face; a like plurality of electrical contacts, each having a mating portion, a solder tail substantially perpendicular thereto, and a bend therebetween, the mating portion being received in a respective passage from the rear face, the solder tails being received proximate the rear face and generally parallel thereto, the solder tails having distal ends proximate the mounting face for disposition against the circuit board; a rib extending across the rear face of the housing having parallel channels with generally V-shaped configuration, a portion of each solder tail having an arcuate surface being disposed resiliently against a respective channel, the channels having a larger width than the solder tails, whereby the arcuate surfaces of the portions of the solder tails cooperate with the V-shaped channels to enable the solder tails to be self-centering in the channels, while still permitting lateral movement as required, thus saving the solder joints from stress levels which could break a joint.
Claim 2
Dependent Claim 201 words
A connector for mounting to a printed circuit board, comprising: a housing having a mating face, an opposed rear face, a mounting fsce perpendicular to the mating face and the rear face, and a plurality of contact receiving passages between the mating face and the rear face; a like plurality of electrical contacts, each having a mating portion, a solder tail substantially perpendicular thereto, and a bend therebetween, the mating portion being received in a respective passage from the rear face, the solder tails being received proximate the rear face and generally parallel thereto, the solder tails having distal ends proximate the mounting face for disposition against the circuit board; a rib extending across the rear face of the housing having parallel channels with generally V-shaped configuration, a portion of each solder tail having an arcuate surface being disposed resiliently against a respective channel, the channels having a larger width than the solder tails, whereby the arcuate surfaces of the portions of the solder tails cooperate with the V-shaped channels to enable the solder tails to be self-centering in the channels, while still permitting lateral movement as required, thus saving the solder joints from stress levels which could break a joint.
Claim 3
Dependent Claim 57 words
A connector as in claim 1 wherein the bend of each contact forms an acute angle between the mating portion and the solder tail, the solder tail being disposed at a substantially right angle to the mating portion when the mating portion is retained in the passage, whereby the tails are disposed resiliently in the respective channels.
Claim 4
Dependent Claim 17 words
A connector as in claim 1 wherein the rib has a single row of parallel channels therein.
Claim 5
Dependent Claim 43 words
A connector as in claim 1 wherein the mating portions of the contacts lie in two parallel rows, the contacts in each row being spaced a first distance apart, the distal ends lying in a single row spaced at half said first distance.
Claim 6
Dependent Claim 69 words
A connector as claim 1 wherein each contact further comprises a retaining portion between said mating portion and said bend, said retaining portion being received in said passage in interference, said contact further comprising a cantilever portion between said retaining portion and said bend, said passage accommodating said arm to permit deflection away from said mounting face, whereby said distal ends may comply resiliently with said printed circuit board.
Claim 7
Dependent Claim 24 words
A connector as in claim 1 wherein the portion of each contact disposed in the respective channel is formed with a generally V-shaped cross-section.
Claim 8
Dependent Claim 39 words
A connector as in claim 1 wherein each contact is stamped and formed and further comprises a retaining plate having sheared edge surfaces received in said passage in interference, each plate being stamped with a hump to facilitate insertion.
Claim 9
Dependent Claim 198 words
A connector for mounting to a printed circuit board, comprising: a housing having a mating face, an opposed rear face, a mounting face perpendicular to the mating face and the rear face, and a plurality of contact receiving passages between the mating face and the rear face, a like pluraity of electrical contacts, each having a mating portion, a tail portion substantially perpendicular thereto, and a band therebetween, the mating portion being received in a respective passage from the rear face, the tail portion being received proximate the rear face and generally parallel thereto, the tail portions having distal ends for electrical connection with conductive areas of the circuit board, a rib extending across the rear face of the housing having parallel channels, each channel being defined by opposed walls and a back surface, the opposed walls forming the channel width, each tail portion being disposed resiliently against a respective channel back surface, the channels having a larger width than the tail portions, whereby the tail portions cooperate with the channel back surface to enable the tail portions to be self-centering in the channels, while still permitting lateral movement of the tail portions in the channels as required.
Claim 10
Dependent Claim 198 words
A connector for mounting to a printed circuit board, comprising: a housing having a mating face, an opposed rear face, a mounting face perpendicular to the mating face and the rear face, and a plurality of contact receiving passages between the mating face and the rear face, a like pluraity of electrical contacts, each having a mating portion, a tail portion substantially perpendicular thereto, and a band therebetween, the mating portion being received in a respective passage from the rear face, the tail portion being received proximate the rear face and generally parallel thereto, the tail portions having distal ends for electrical connection with conductive areas of the circuit board, a rib extending across the rear face of the housing having parallel channels, each channel being defined by opposed walls and a back surface, the opposed walls forming the channel width, each tail portion being disposed resiliently against a respective channel back surface, the channels having a larger width than the tail portions, whereby the tail portions cooperate with the channel back surface to enable the tail portions to be self-centering in the channels, while still permitting lateral movement of the tail portions in the channels as required.
Claim 11
Dependent Claim 21 words
A connector as in claim 8 wherein each tail portion has at least one arcuate surface disposed resiliently against the channel.
Claim 12
Dependent Claim 22 words
A connector as in claim 8 wherein each channel back surface has a generally arcuate configuration which cooperates with the tail portion.
