Electrical connector contact enabling detection of the presence of a mating connector contact
First Claim
1. A connection indication system for an automatic termination system for a bus device comprising:
- a device connector on the bus device;
a sense line;
a female contact in the device connector, the female contact further comprising a first part and a second part, the first part electrically isolated from the second part, the first part further electrically connected to the sense line and the second part electrically connected to a voltage potential; and
the sense line electrically connected to the automatic termination system.

Abstract
An electrical connector having a female contact that enables detection of the presence of a corresponding male contact. The female contact is divided into two parts. The two parts are electrically isolated. When a male pin is installed in the female contact, the male pin electrically connects the two parts of the female contact together. In a specific application, the female contact is in a connector for an external device on a SCSI computer bus. The first part is pulled high and serves as a sense line. The second part is pulled to ground. A pin in the mating connector electrically connects the two parts of the female contact, pulling the sense line to ground. The external device disables internal termination of the SCSI bus when the sense line is pulled low. In an alternative embodiment, the external device has two SCSI connectors, each with a two-part female contact. The external device in the alternative embodiment disables internal termination of the SCSI bus when both of the SCSI connectors have mating connectors installed.
