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 open channel is arranged in-between the intermediate portions of the first and second leads, the first channel being defined by a web of the first dielectric material between the first and second leads and surfaces of the first dielectric material substantially surrounding the intermediate portions between the first end and the second end of each lead and extending substantially over a length from the first end to the second end of each lead and substantially completely making up the volume in-between said two adjacent leads;

wherein said channel is filled with a second dielectric medium; and

further comprising 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

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.

2. Lead frame assembly according to claim 1, 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.

3. Lead frame assembly according to claim 1, 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.

4. Lead frame assembly according to claim 3, 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.

5. Lead frame assembly according to claim 3, 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.

6. Lead frame assembly according to claim 5, 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.

9. Connector assembly comprising one or more lead frame assemblies according to claim 1.

7. Lead frame assembly for an electrical connector, comprising a first lead, a second lead and a third lead, and a frame made of a dielectric material,

the leads having a first end, a second end and an intermediate portion between the first end and the second end,

wherein the leads are substantially surrounded by the dielectric material, over the whole length of their intermediate portions,

wherein the frame comprises at least a first channel and a second channel in the dielectric material, wherein the first channel is arranged in-between the intermediate portions of the first and second leads, separating the first and second leads by an air gap, and the second channel is arranged in-between the intermediate portions of the second and third leads, separating the second and third leads by an air gap,

the first and second channels being defined by at least three sides and having lengths extending substantially from the first end to the second end of each of the leads in directions substantially parallel to the intermediate portions of the first and second leads and the second and third leads, respectively,

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 the second channel 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,

and wherein said channels substantially completely make up the volume in-between said first, second and third adjacent leads.

8. Lead frame assembly for an electrical connector, comprising a first lead, a second lead and a third lead, and a frame made of a dielectric material, the leads having a first end, a second end and an intermediate portion between the first end and the second end, wherein the leads are substantially surrounded by the dielectric material, over the whole length of their intermediate portions, wherein the frame comprises at least a first channel and a second channel in the dielectric material, wherein the first channel is arranged in-between the intermediate portion of the first and second leads, separating the first and second leads by an air gap, and the second channel is arranged in-between the intermediate portion of the second and third leads, separating the second and third leads by an air gap, the first and second channels being defined by at least three sides and having a length extending in a direction substantially parallel to the intermediate portions of the first and second leads and the second and third leads, respectively,

wherein said channels substantially completely make up the volume in-between said first, second and third adjacent leads

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,

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.
