Abstract

Abstract An electrical connector is shown which is mountable to a printed circuit board (200) which includes a plurality of insulating housings (4). A vertical row of terminals is formed as a subassembly (60) where the terminals (72 to 75) are integrally molded within an insert (82) of dielectric material. The lengths of the sections of the terminals (72 to 75) which are within the molded insert (82) vary to alter the impedance of the terminals (72 to 75), thereby matching the overall impedance of the terminals (72 to 75). Cross-talk shield members are insertable into the rear of each connector housing (4) to shield adjacent vertical rows of terminals from cross-talk. Upper (100) and lower shield members are insertable over the assembly to shield the assembly from EMI/RFI.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 141 words
A controlled impedance right angle electrical connector assembly (2) comprising: an insulating housing (4) having a front mating face (6) and a rear face (14); and at least one terminal module (60,60′) characterized in that the module comprises: (a) a stamped lead frame (62) including a plurality of edge stamped right angle contacts (64,65,66,67,67′) where the contacts each include a printed circuit board interconnection section (76,77,78,79), an intermediate section (72,73,74,75) and a mating contact section (68,69,70,71,71′); each consecutive intermediate section (72,73,74,75) increasing in length from the prior and adjacent contact, and (b) an overmolded insert (82) which encapsulates at least a portion of the intermediate portions (72,73,74,75) in an insulative material leaving the remainder of the intermediate portion (72,73,74,75) exposed to the air, whereby the combination of the encapsulation and exposure to air balances the impedance of the plurality of contacts.
Claim 2
Dependent Claim 141 words
A controlled impedance right angle electrical connector assembly (2) comprising: an insulating housing (4) having a front mating face (6) and a rear face (14); and at least one terminal module (60,60′) characterized in that the module comprises: (a) a stamped lead frame (62) including a plurality of edge stamped right angle contacts (64,65,66,67,67′) where the contacts each include a printed circuit board interconnection section (76,77,78,79), an intermediate section (72,73,74,75) and a mating contact section (68,69,70,71,71′); each consecutive intermediate section (72,73,74,75) increasing in length from the prior and adjacent contact, and (b) an overmolded insert (82) which encapsulates at least a portion of the intermediate portions (72,73,74,75) in an insulative material leaving the remainder of the intermediate portion (72,73,74,75) exposed to the air, whereby the combination of the encapsulation and exposure to air balances the impedance of the plurality of contacts.
Claim 3
Dependent Claim 31 words
The connector of claim 1 characterized in that intermediate sections (72,73,74,75) extend at a designated angle which interconnects the printed circuit board interconnection sections (76,77,78,79) with the mating contact section (68,69,70,71,71′).
Claim 4
Dependent Claim 32 words
The connector of claim 2 characterized in that the overmolded insert (82) includes a first leg (82b) which spans the intermediate portions (72,73,74,75) adjacent to the printed circuit board interconnection section (76,77,78,79).
Claim 5
Dependent Claim 31 words
The connector of claim 3 characterized in that the overmolded insert (82) includes a second leg (82b) portion which spans the intermediate portions (72,73,75,75) adjacent to the mating contact section (68,69,70,71).
Claim 6
Dependent Claim 26 words
The connector of claim 4 characterized in that the length of the intermediate section (72,73,74,75) within the second leg portion (82a) varies within the contacts (64,65,66,67,67′).
Claim 7
Dependent Claim 21 words
The connector of claim 1 characterized in that modules (60,60′) are insertable into the housing (4) through the rear face (14).
Claim 8
Dependent Claim 32 words
The connector of claim 6 characterized in that the modules (60) are dimensioned to stack one against the other, to align the mating contact sections (68,69,70,71,71′) with the pin receiving openings (16a-­16e).
Claim 9
Dependent Claim 19 words
The connector of claim 6 characterized in that the modules (60′) include between them a planar shield member (180′).
Claim 10
Dependent Claim 37 words
The connector of claim 8 characterized in that the modules (60′) and the shield members (180′) are dimensioned to stack one against the other, to align the mating contact sections (68,69,70,71,71′) with the pin receiving openings (16a-16e).
