Abstract

A lead frame assembly for an electrical connector is provided. The lead frame assembly includes a first lead, a second lead adjacent the first lead and a dielectric material. The leads have a first end, a second end and an intermediate portion between the first end and the second end. The leads are received within the dielectric material with the intermediate portions being substantially surrounded by the dielectric material. The dielectric material includes at least a first channel in the dielectric material arranged in-between the first and second leads. The first channel is defined by at least three sides and has a length extending in a direction substantially parallel to the intermediate portions of the first and second leads.

Claims

1. Lead arrangement for a connector, comprising a first lead and a second lead adjacent the first lead fully positioned in the same plane as the first lead, the leads having a first end, a second end and an intermediate portion substantially surrounded, between the first end and the second end, by a first dielectric material

wherein a first channel is arranged in-between the intermediate portions of the first and second leads and substantially completely makes up the volume in-between said two adjacent leads and wherein said channel is filled with a second dielectric medium.

2. Lead frame assembly for an electrical connector, comprising a lead arrangement according to claim 1, and a frame made of dielectric material, wherein the frame comprises at least said first channel arranged in-between the intermediate portions of the first and second leads, and extending substantially over the whole length of the intermediate portions of the first and second leads.

3. Lead frame assembly according to claim 2, wherein at least the first channel is defined by three sides and is open towards a first side of the assembly along at least a first portion of the length of the first channel.

4. Lead frame assembly according to claim 2, wherein at least the first channel is open towards a first side of the assembly along at least a first portion of the length of the channel and is open towards a second side of the assembly along at least a second portion of the length of the channel.

5. Lead frame assembly according to claim 2, wherein the first channel is open towards a first side of the assembly along at least a first portion of the

length of the first channel and is open towards a second side of the assembly along at least a second portion of the length of the first channel, and wherein a second channel between the intermediate portions of the first or second lead and a third lead is open towards the second side of the assembly along at least a first portion of the length of the second channel and is open towards the first side of the assembly along at least a second portion of the length of the second channel.

6. Lead frame assembly according to claim 5, wherein the first portion of the length of the first channel substantially corresponds with the first portion of the length of the second channel, taken in the direction of the channels.

7. Lead frame assembly according to claim 5, wherein the first channel is open towards a first side of the assembly along a plurality of portions of the length of the first channel and is open towards a second side of the assembly along a plurality of portions of the length of the first channel and wherein the second channel is open towards the second side of the assembly along a plurality of portions of the length of the second channel and is open towards the first side of the assembly, along a plurality of portions of the length of the second channel.

8. Lead frame assembly according to claim 7, wherein the portions of the length of the first channel substantially correspond with the portions of the length of the second channel, taken in the direction of the channels.
