Abstract:
A cable backplane system includes a backplane having a plurality of openings therethrough and a cable rack coupled to a rear of the backplane. The cable rack includes a tray having a frame surrounding a raceway and a brick held by the tray. The brick has side spacers at opposite sides of the brick and plates coupled to the side spacers that support a plurality of cable connector assemblies. Each cable connector assembly is positioned between and supported by corresponding plates on opposite sides of the cable connectors with the cable connectors positioned in corresponding openings in the backplane. The plates each include a hem folded over at a rear of the plate. The hem has an edge positioned rearward of the cable connectors and supporting the cable connectors from retreating from the openings in the backplane.
Abstract:
Electrical connector including a connector housing having a mating side that faces in a mating direction. The mating side configured to engage a mating connector. The electrical connector also includes an electrical contact held by the connector housing. The electrical contact includes a common body section and first, second, and third contact beams that are arranged along the mating side and have respective contact bases coupled to the body section. Each of the first, second, and third contact beams extend in the mating direction from the respective contact base to a respective distal end. Each of the first, second, and third contact beams has a beam length that is measured from the respective contact base to the respective distal end. The beam lengths of the first, second, and third contact beams being different from one another.
Abstract:
An electrical power contact includes a mating segment having a mating interface at which the electrical power contact is configured to mate with a mating contact. The mating segment includes an electrically conductive base layer, and an electrically conductive outer layer that includes the mating interface. The mating segment also includes a circuit protection layer that extends between the base layer and the outer layer. The circuit protection layer provides an electrical pathway between the base layer and the outer layer. The circuit protection layer includes a selectively conductive material that is configured to open the electrical pathway between the base layer and the outer layer when an electrical current above a predetermined threshold is passed through the circuit protection layer.
Abstract:
A cable backplane system includes a backplane having a plurality of openings extending between a front and a rear of the backplane. The backplane has mounting locations proximate the openings. Mounting blocks are coupled to the front of the backplane at corresponding mounting locations. The mounting blocks are secured to the backplane by fasteners. A cable rack is coupled to the rear of the backplane and has a tray with a frame surrounding a raceway and spacers coupled to the tray. The spacers hold corresponding cable connectors and are secured to corresponding mounting blocks to position the spacers and cable connector assemblies relative to the backplane. The cable connectors are received in corresponding openings in the backplane and are held in position relative to the backplane by the spacers and mounting blocks.
Abstract:
A cable backplane system includes a backplane and a chassis supporting the backplane. A cable rack is coupled to the chassis and backplane. The cable rack includes upper trays and lower trays each having a frame and cable connector assemblies held by the corresponding frame. The upper trays have upper tray guides configured to interact with corresponding upper chassis guides on the upper support for supporting the upper trays relative to the backplane. The lower trays have lower tray guides configured to interact with corresponding lower chassis guides on the lower support for aligning the lower trays to the backplane. The upper trays have upper hanging guides and the lower trays have lower hanging guides coupled to corresponding upper hanging guides to support the lower trays with the corresponding upper trays relative to the backplane.

A cable backplane system includes a backplane having a plurality of openings therethrough and a plurality of mounting blocks. A cable rack is coupled to a rear of the backplane and includes a tray having a frame surrounding a raceway. Spacers are coupled to the tray that are secured to corresponding mounting blocks to position the spacers relative to the backplane. Cable connector assemblies are held by the tray. Each cable connector assembly has a plurality of cables extending between at least two cable connectors. The cables are routed in the raceway. Each cable connector assembly is positioned between and supported by corresponding spacers on opposite sides of the cable connector assemblies. The spacers allow limited movement of the cable connectors in at least two directions to allow alignment of the cable connectors within corresponding openings in the backplane.
Abstract:
Electrical contact having a body portion and a compliant contact tail that is coupled to the body portion and configured to be inserted into a plated thru-hole (PTH). The contact tail extends from the body portion along a central axis to a leading end. The contact tail includes first and second compliant regions that are located between the leading end and the body portion. The contact tail has a joint region that joins the first and second compliant regions. Each of the first and second compliant regions is dimensioned to mechanically engage the PTH when inserted therein. The joint region is dimensioned smaller than the first and second compliant regions such that the joint region moves freely through the PTH.

Abstract:
A cable backplane system includes a backplane having board areas surrounding a connector opening with holes in the board areas along the connector opening. Stiffeners are coupled to corresponding board areas along a front of the backplane. The stiffeners have bores aligned with corresponding holes in the backplane. A cable rack is coupled to the rear of the backplane. The cable rack has a tray with a frame surrounding a raceway and spacers coupled to the tray that hold corresponding cable connectors. The spacers have guide pins extending therefrom that pass through the holes in the backplane into corresponding bores in the stiffeners to position the spacers relative to the stiffeners and the backplane. The cable connectors are received in the connector opening in the backplane and held in position relative to the backplane by the spacers and stiffeners.
