Abstract

The high-speed electrical transmission cable connector assembly of this invention includes an electrical connector having a connector backshell with an internal cavity for receiving an electrical insert to interface with an electrical interface device. An adequate amount of space is provided by the internal cavity within the backshell for routing wires of the transmission cable through a neck in an entrance side of the backshell to terminate within the insert. The backshell has a truncated side and a short lateral side for saving space and weight of the electrical connector. A grounding terminal is carried within the internal cavity of the backshell adjacent to the neck on a short neck side for grounding wires within a short distance inside the backshell. An attachment and release mechanism is provided for connecting and disconnecting the interface device to the electrical insert within the backshell. A pair of attachment clips are provided inside a clip channel on two sides of the backshell for attaching and releasing the interface device to the electrical connector.

Claims

1. An electrical connector for connecting wires of a high speed transmission cable with an associated electrical interface device along parallel axis, the connector comprising:

an electrical cable comprising a plurality of wires;

a backshell comprised of a first conductive shell and a second conductive shell forming an interior cavity accessible for receiving said wires and said electrical insert within said interior cavity;

an open backshell face for mounting said electrical insert in position to provide a mating interface between said interface device and said insert;

said first and second shells form an entrance side which extends generally perpendicular to said open backshell face, said entrance side having an entrance opening and an entrance neck which extends generally parallel with said backshell face outwardly from at least one of said first and second shells, said entrance opening being adapted to receive said cable over said entrance neck to route said wires of said cable to said interior cavity along a cable axis at an angle to said interface axis;

a retaining clamp mounted over said entrance neck for securing said cable to said neck such that said retaining clamp can be removed while said shells are secured together;

a grounding terminal carried within said interior cavity of said backshell adjacent said entrance opening for grounding selected of said wires to said backshell; and

an attachment mechanism including a pair of manually controlled clips for selectively engaging with and releasing from said associated interface device of said electrical insert.

2. The electrical connector of claim 1 wherein said backshell includes a lateral side arranged opposite and extending parallel of said entrance side, a short neck side extending parallel with said entrance side and a truncated side interfacing with ends of said lateral side and said neck side, said truncated side extending at an angle of between 20 and 40 degrees to the axis of said lateral and neck sides.

3. The connector assembly of claim 1 wherein said connector mechanism further includes;

a clip channel formed within said backshell adjacent said entrance side and an opposed lateral side for receiving said clips;

a pivot pin arranged within each channel forming a pivot axis for said attachment clips;

each said attachment clip including an attachment stem arranged above said pivot and within a respective of said channels, said clip having an attachment flange for engaging an interface attachment of said interface device for holding said interface device in an attached relationship with said electrical insert;

a clip spring engaging with an interior surface of said channel adjacent said attachment stem for biasing said attachment flange into said engaging position with said interface attachment; and

,

a clip release arm arranged below said pivot and parallel with said attachment stem for manually pivoting said attachment stem about said pivot axis to disengage said attachment flange from said interface attachment prior to disconnecting said interface device from said electrical connector.

4. The connector assembly of claim 3 wherein each said channel includes an entrance opening of a width not greater than about 70 percent of a maximum width of said channel at a location adjacent said pivot axis.

5. The connector assembly of claim 3 wherein said clip channels each include an exterior backshell wall having and end portion forming a part of said open backshell face and said interface device includes a mounting plate, said mounting plate engaging with said backshell face sealing upper ends of said channels when said interface device is engaged with said insert.

6. The connector assembly of claim 1 wherein said angle between said interface axis and said cable axis is approximately 90 degrees.

7. The connector assembly of claim 1 wherein said connector backshell is made of a 6061-T6 aluminum alloy material with an electroless nickel finish.

8. The connector assembly of claim 1 wherein said attachment clips comprise a single piece of a beryllium copper alloy 25 material, as defined by the American Society of Testing Materials Specification No. B194, which is heat treated at 600°

F. for three hours before receiving an electroless nickel finish.
