Abstract
Disclosed are connector systems for power and/or data transfer in breathing apparatus. The connector systems may comprise magnetically attractive elements and magnets. The connector systems may comprise protrusions and complimentary recesses which are aligned perpendicularly to a cable axis of the connector or connectors. Also disclosed are breathing apparatus comprising the connector systems, and breathing apparatus charging systems.
Claims17
A breathing apparatus comprising a wearable support frame, wherein the wearable support frame comprises a connector system comprising:
- a first connector provided on the wearable support frame, the first connector comprising an electrical transfer element and a non-magnetized, magnetically attractive element to be attracted by a magnet;
- a second connector for connection to the first connector, comprising a complementary electrical transfer element for power and/or data transfer with the electrical transfer element of the first connector and further comprising a magnet for attracting the magnetically attractive element so as to magnetically secure the first and second connector to one another for power and/or data transfer between the electrical transfer elements;
- and
- wherein the magnetically attractive element is covered by a non-conducting material such that the magnetically attractive element is not exposed on a surface of the first connector.
A breathing apparatus comprising a wearable support frame, wherein the wearable support frame comprises a connector system for power and/or data transfer, comprising:
- a first connector comprising a contact protrusion having at least first and second electrical contacts, the electrical contacts defining a contact axis along a straight line extending between the first and second contacts, and the first connector comprising a non-magnetized, magnetically attractive element to be attracted by a magnet;
- a second connector comprising a complementary recess for receiving the contact protrusion having complementary electrical contacts for contacting the first and second electrical contacts of the first connector, and the second connector comprising a magnet for attracting the magnetically attractive element so as to magnetically secure the first and second connector to one another;
- wherein at least one of the first and second connectors is attached to a cable and, at a connection interface between the cable and the connector, a longitudinal axis of the cable is substantially perpendicular to the contact axis;
- wherein the contact protrusion and the complementary recess each comprise a peripheral surface which is inclined with respect to the longitudinal axis of the cable, wherein the inclined peripheral surfaces are configured to overlay one another when the first and second connectors are in a connected configuration;
- and
- wherein the inclined peripheral surfaces are inclined with respect to the longitudinal axis of the cable such that, in the connected configuration, a tensile force applied to the cable will urge the first and second connectors to disconnect as the inclined peripheral surfaces move relative to one another.
