Abstract

An electrical communication system includes at least one electrical connector system that includes a header connector configured to mate with a receptacle connector through a back panel. The connector system includes a latch that releasably mates the header and receptacle connectors. The receptacle connector is mounted to a substrate, such as a printed circuit board, and the header connector is connected to a power cable assembly. The power cable assembly includes a faston that electrically connects a power cable to the electrical contacts of the header connector.

Claims

1. A electrical communication system configured to be mounted through an opening formed in a back panel, the communications system comprising:

a first electrical connector including a first housing that retains a first plurality of electrical power contacts, the first electrical connector defining a mating end and a mounting end, wherein the mounting end is configured to mate with a cable assembly;

a second electrical connector including a second housing that retains a second plurality of electrical power contacts, the second electrical connector defining a mating end configured to mate with the mating end of the first electrical connector, and a mounting end configured to mount onto a substrate, wherein the second electrical connector includes a latch retainer projecting out from the second housing; and

no more than a single latch mounted to the first housing and extending through the opening formed in the back panel, the latch being configured for actuation between an engaged configuration, whereby the latch engages the latch retainer so as to prevent the first and second electrical connectors from separating, and a disengaged configuration, whereby the latch is out of engagement with the latch retainer so as to allow the first and second electrical connectors to separate from each other.

2. The electrical communication system as recited in claim 1, wherein the latch includes a latch body, a spring flange extending inward from the latch body and bearing against the first housing, and a barb projecting inward from the latch body, wherein the barb is configured to removably engage the latch retainer.

3. The electrical communication system as recited in claim 2, wherein the barb defines a beveled leading edge and the latch retainer defines a projection having a beveled edge, whereby the barb cams over the beveled edge of the projection when the first and second electrical connectors are mated.

4. The electrical communication system as recited in claim 1, wherein the spring flange biases the barb into interference with the latch retainer.

5. The electrical communication system as recited in claim 1, further comprising a bracket mounted onto the first housing, wherein the latch is pivotally mounted to the bracket, and pivots between the engaged configuration and the disengaged configuration.

6. The electrical communication system as recited in claim 1, wherein the first electrical connector is configured to mate with a pair of cable assemblies, each cable assembly including a faston that is connected to a cable, and the housing defines an organizer that receives one of the cables and maintains the received cable in a predetermined position separate from the other cable.

7. The electrical communication system as recited in claim 6, wherein the organizer further provides strain relief to the cable.

8. The electrical communication system as recited in claim 1, wherein the first electrical connector comprises a header connector, and the first plurality of electrical contacts comprise header contacts, and the second electrical connector comprises a receptacle connecter contacts that receive a portion of the header contacts when the header and receptacles connectors are mated.

9. The electrical communication system as recited in claim 1, further comprising a plurality of first and second electrical connectors connected on a common back panel, wherein the plurality of second electrical connectors is mounted onto a common substrate.

10. The electrical communication system as recited in claim 8, wherein each of the plurality of first electrical connectors is disposed immediately adjacent each other such that substantially no space is disposed between the adjacent first connectors.

11. The electrical communication system as recited in claim 10, wherein nine of the first electrical connectors fit along a length of 110 mm along the back panel.

14. The electrical communication system as recited in claim 10, wherein the cable organizer comprises a cable position control slot extending through the first housing.

15. The electrical communication system as recited in claim 14, wherein the cable position control slot includes a neck having first end that is open, and a second end that is connected to an eyelet, wherein the neck has a dimension less than that of the associated cable, and the cable is inserted through the neck into the eyelet.

12. A electrical communication system configured to be mounted onto a back panel, the communications system comprising:

a cable connector assembly including;

a first electrical connector including a first housing that retains a first plurality of electrical power contacts, the first electrical connector defining a first mating end and a first mounting end,

a cable assembly configured to electrically connect the first electrical connector to an external electrical device, the cable assembly including a faston that defines a second mating end that is inserted inside the first mounting end, and a second mounting end that extends perpendicular to the mating end, the faston retaining a receptacle contact electrically connected between a cable and one of the first electrical power contacts;

wherein the faston provides strain relief to the cable, and the first housing provides a cable organizer that receives the cable and maintains the cable in a position spaced from an adjacent cable; and

a second electrical connector including a second housing that retains a second plurality of electrical power contacts, the second electrical connector defining a third mating end configured to mate with the first mating end, and a third mounting end configured to mount onto a substrate.

13. The electrical communication system as recited in claim 12, wherein the faston is press-fit in the first mounting end.
