CONNECTOR SYSTEM IMPEDANCE MATCHING

摘要

Connector inserts and receptacles that provide signal paths having desired impedance characteristics. One example may provide a connector system having a connector insert and a connector receptacle. Contacts in the connector insert may form signal paths with corresponding contacts in the connector receptacle. Additional traces in the connector insert and receptacle may be part of these signal paths. The signal paths may have a target or a desired impedance along their lengths such that the power paths electrically appear as transmission lines. Constraints on physical dimensions of the connector insert and connector receptacle contacts may result in variations in impedance along the signal paths. Accordingly, embodiments of the present invention may provide structures to reduce these variations, to compensate for these variations, or a combination thereof.

主权项

1. A connector system comprising:
a connector insert having a first contact; and a connector receptacle comprising:
a second contact; anda first trace on a tongue, the first trace coupled to the second contact, wherein the first contact engages the second contract, and wherein the first contact, the second contact, and first trace form a signal path when the connector insert is inserted in the connector receptacle, and wherein the signal path has an average impedance along its length, the impedance of the signal path at the second contact is lower than the average impedance and the impedance of the signal path along at least a portion of the first trace is higher than the average impedance.
