Abstract
Abstract Connector for ribbon cable comprises a housing having rows of terminals with C-shaped body portions in respective rows of passages of square cross section. Each body portion has a substantially planar first plate which extends to a coplanar slotted plate portion which receives a cable conductor. The plate is stamped with opposed lugs which engage opposite walls of the passage for angular orientation which does not depend on formed dimensions of the body portion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
232 words
An electrical connector for use in establishing electrical connections to the conductors of a flat cable of the type comprising a plurality of conductors held in spaced side-by-side parallel relationship by plastic insulating material, the electrical connector comprising: a housing member having a mating end and a cable receiving end; a plurality of terminal passages extending from the mating end through the cable receiving end; a like plurality of terminals positioned in the passages having cantilever contact engaging members extending from a midsection of the terminals; and a rib positioned in the passages on a wall thereof, the ribs extend from proximate the mating end toward the cable receiving end, the end of the rib toward the cable receiving end of the passage being tapered, the tapered end of the rib providing diverging surfaces such that as a terminal is inserted into the passage the cantilever contact engaging members engage respective tapered surfaces, forcing the members into the prestressed position to allow for insertion of a matable contact under reduced insertion force, the tapered end of the rib also engaging the bottom surface of the midsection of the terminal such that a stop position is reached thereby assuring that proper alignment of the terminal is maintained, ensuring a positive electrical connection is established with the matable contact and preventing the terminal from axial movement during insertion of a conductor in the terminal.
Claim 2
Dependent Claim

An electrical connector for use in establishing electrical connections to the conductors of a flat cable of the type comprising a plurality of conductors held in spaced side-by-side parallel relationship by plastic insulating material, the electrical connector comprising: a housing member having a mating end and a cable receiving end; a plurality of terminal passages extending from the mating end through the cable receiving end; a like plurality of terminals positioned in the passages having cantilever contact engaging members extending from a midsection of the terminals; and a rib positioned in the passages on a wall thereof, the ribs extend from proximate the mating end toward the cable receiving end, the end of the rib toward the cable receiving end of the passage being tapered, the tapered end of the rib providing diverging surfaces such that as a terminal is inserted into the passage the cantilever contact engaging members engage respective tapered surfaces, forcing the members into the prestressed position to allow for insertion of a matable contact under reduced insertion force, the tapered end of the rib also engaging the bottom surface of the midsection of the terminal such that a stop position is reached thereby assuring that proper alignment of the terminal is maintained, ensuring a positive electrical connection is established with the matable contact and preventing the terminal from axial movement during insertion of a conductor in the terminal.
Claim 3
Dependent Claim
61 words
An electrical connector as recited in claim 1 wherein each terminal has a generally C-shaped midsection which comprises a substantially planar first plate extending to a coplanar slotted plate position, the first plate being stamped with a pair of opposed lugs which engage opposite walls of the passage creating an interference fit of the terminals in the passages of the connector.
Claim 4
Dependent Claim
32 words
An electrical connector as recited in claim 2 wherein each passage has a pair of lead-ins at the cable receiving end for guiding the respective lugs of the terminals into the passages.
Claim 5
Dependent Claim
221 words
An electrical connector for termination of flat ribbon cable comprising: a dielectric housing member having a cable receiving end, a mating end, and a plurality of rectangular-shaped passages extending therethrough, each of said passages having a rib on a wall thereof, said rib extending from proximate the mating end to a tapered end toward the cable receiving end of the passages; and a like plurality of terminals received in respective passages, each terminal comprising a body portion of generally C-shaped cross-section having a first plate, a parallel third plate, and a second plate extending substantially normally therebetween and engaging the tapered end of the rib, the first and third plates having respective cantilever arms extending therefrom to contact surfaces for engaging a pin, said cantilever arms maintained in a prestressed position by the rib to allow insertion of a mating contact under reduced insertion force, the first plate extending to a coplanar slotted plate, the first plate having a pair of opposed lugs which are received in passage lead-ins to align the terminals in the passage as the terminals are inserted into the passages, the lugs cooperate with the walls of the passage to provide an interference fit in the dielectric housing member so as to maintain proper angular orientation of the terminal as well as retain the terminal against withdrawal.
Claim 6
Dependent Claim
221 words
An electrical connector for termination of flat ribbon cable comprising: a dielectric housing member having a cable receiving end, a mating end, and a plurality of rectangular-shaped passages extending therethrough, each of said passages having a rib on a wall thereof, said rib extending from proximate the mating end to a tapered end toward the cable receiving end of the passages; and a like plurality of terminals received in respective passages, each terminal comprising a body portion of generally C-shaped cross-section having a first plate, a parallel third plate, and a second plate extending substantially normally therebetween and engaging the tapered end of the rib, the first and third plates having respective cantilever arms extending therefrom to contact surfaces for engaging a pin, said cantilever arms maintained in a prestressed position by the rib to allow insertion of a mating contact under reduced insertion force, the first plate extending to a coplanar slotted plate, the first plate having a pair of opposed lugs which are received in passage lead-ins to align the terminals in the passage as the terminals are inserted into the passages, the lugs cooperate with the walls of the passage to provide an interference fit in the dielectric housing member so as to maintain proper angular orientation of the terminal as well as retain the terminal against withdrawal.
Claim 7
Dependent Claim
28 words
An electrical connector as recited in claim 4 wherein each passage has a pair of lead-ins at the cable receiving end for guiding respective lugs into the passage.
Claim 8
Dependent Claim
26 words
An electrical connector as recited in claim 4 wherein the first plate of the body portion is received substantially flushly against one wall of the passage.
