Abstract

Abstract A right-angled electrical connector (10) includes a dielectric housing (12) having a front mating face (28) and rear face (29) with a plurality of terminal-receiving passages extending therebetween. A plurality of terminals have forwardly projecting contact portions (64) in the passages and right-angled tail portions (66) projecting rearwardly from the housing. At least a first tail portion (66a) is longer than a second tail portion (66b), whereby their respective terminals have circuit paths of different lengths. A ground plate (68) extends alongside of and spaced from the first and second tail portions. A dielectric member (75, 76) is located between the ground plate and one of the first and second tail portions for controlling a circuit characteristic of the circuit path through the terminal of which the one tail portion is a part.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 159 words
In a right-angled electrical connector (10) which includes a dielectric housing (12) mounting at least a pair of terminals, each having a contact portion (64) and a right-angled tail portion (66a, 66b) projecting therefrom, each said tail portion having a board mounting portion at an angle to said contact portion and a transition portion between said board mounting portion and said contact portion and including at least one bent region, the tail portion (66a) of one of said terminals being longer than the tail portion (66b) of the other, and a tail aligning device (20) having apertures therethrough through which a portion of the board mounting portions extend, wherein the improvement comprises dielectric member (75, 76) extending from the tail aligning device alongside both a length of said board mounting portion and said bent region of said transition portion of one of the right-angled tail portions for controlling the relative dielectric constants of the region surrounding the tail portions.
Claim 2
Dependent Claim 48 words
In a right-angled electrical connector as set forth in claim 1, further comprising a ground plate (68) spaced from and extending along substantially the entire length of said pair of terminals and said dielectric member being positioned between one of said right-angled tail portions and said ground plate.
Claim 3
Dependent Claim 41 words
In a right-angled electrical connector as set forth in claim 1 or 2, whwerein said dielectric member (75) is located between the ground plate (68) and the first, longer tail portion (66a) for decreasing the impedance of the circuit path therethrough.
Claim 4
Dependent Claim 41 words
In a right-angled electrical connector as set forth in claim 1 or 2, wherein said dielectric member (76) is located between the ground plate (68) and the second, shorter tail portion (66b) for increasing the propagation delay of a circuit therethrough.
Claim 5
Dependent Claim 33 words
In a right-angled electrical connector as set forth in any preceding claim, wherein said dielectric member comprises a plate-like member (75, 76) that extends in a cantilevered manner from the tail aligning device.
Claim 6
Dependent Claim 31 words
In a right-angled electrical connector as set forth in any preceding claim, wherein said tail aligning device (20) comprises a molded plastic component with the dielectric member (75, 76) integral therewith.
Claim 7
Dependent Claim 34 words
In a right-angled electrical connector as set forth in any preceding claim, further comprising a one piece conductive ground shield (14) having a generally rectangular shroud (44) encircling the contact portions of the terminals.
Claim 8
Dependent Claim 23 words
In a right-angled electrical connector as set forth in any preceding claim, wherein each terminal is a stamped and formed one piece member.
Claim 9
Independent Claim 181 words
A system for preferentially controlling one of (a) the impedance and (b) the propagation delay circuit characteristics of an electrical connector (10) which has a dielectric housing (12) mounting at least a pair of stamped and formed terminals having tail portions (66a, 66b) projecting therefrom, one of the tail portions being longer than the other, and a ground member (68) spaced from and extending along substantially the entire length of each of the terminals, comprising: selectively positioning a dielectric member (75, 76) alongside only one of the tail portions and between said one of the tail portions and the ground member to alter the dielectric constant thereof depending on which of the characteristics (a) and (b), above, is desired to be preferentially controlled, whereby positioning the dielectric member alongside the longer of the tail portions (66a) will increase the dielectric constant thereof and, thereby, decrease the impedance of a circuit therethrough, and whereby positioning the dielectric member alongside the other of the tail portions (66b) will increase the dielectric constant thereof and, thereby, increase the propagation delay of a circuit therethrough.
