Abstract
Connector inserts having reliable contacts, as well as connector receptacles having improved magnetic circuits for use in electronic devices having a thin form factor. These and other examples can provide connector receptacles that can be easily aligned to an opening in an electronic device, as well as connector inserts and connector receptacles that can be readily manufactured.
Claims20
A spring-loaded contact comprising:
- a barrel having a front opening;
- a plunger having a tip extending through the front opening and a body housed in the barrel;
- a spring housed in the barrel;
- and
- an intermediate object between a backside of the plunger and the spring, where the intermediate object simultaneously contacts an inside surface of the barrel at a first location and a second location, the first location and the second location on opposite sides of the intermediate object, and
- wherein the first location is a first distance from the front opening and the second location is a second distance from the front opening, the first distance different than the second distance.
