Robust magnetic connector
First Claim
1. A connector receptacle comprising:
- a plurality of magnets arranged at a face of the connector receptacle;
a ground return at the face of the connector receptacle and covering the plurality of magnets such that the ground return is between a connector insert and the plurality of magnets when the connector insert is mated with the connector receptacle;
a depressible power contact having a first end extending beyond the face of the connector receptacle and a second end extending behind the plurality of magnets;
a spring at the second end of the depressible power contact and fixed relative to the ground return, anda stop positioned to limit a distance the depressible power contact can be depressed.

Abstract
Connector inserts and receptacles that are robust, easily manufactured, and provide an improved connector performance. One example may provide a connector receptacle having a power contact located in a ground surface. An insulating layer may be placed between the power contact and the ground surface. The ground surface may be curved or flat, or it may have other shapes. Another example may provide a robust connector insert. This connector insert may include a crimping piece that fits over a cable braiding and is crimped. The crimping piece may then be attached to an attraction plate. A cover or shell may be attached to provide further reinforcement. Another example may provide a connector system having a ground contact and a power contact, where the ground contact is a make-first-break-last contact.

13. A connector insert comprising:
-
a cable having braiding and a power conductor, where the power conductor emerges from a first end of the cable and the braiding is pulled back around the cable at the first end of the cable; an insulating layer at the first end of the cable having an opening for the power conductor; a power cap fixed to the power conductor such that the insulating layer is between the first end of the cable and the power cap; a power insulator around sides of the power cap; an attraction plate around the power insulator; a crimping piece over the braiding and secured to the attraction plate; and a shell over a rear portion of the attraction plate, wherein the attraction plate is fixed to the shell by a plurality of pins in the attraction plate fit into a groove in the shell. - View Dependent Claims (14, 15)
