Electromechanical braking connector
(57) Abstract

An electromechanical braking (EMB) connector for electrical communication between an interior of a brake caliper assembly and an exterior of the brake caliper assembly is disclosed. The EMB connector includes a body having a distal end for insertion into the interior of the brake caliper assembly and a proximal end for exposure on the exterior of the brake caliper assembly, with the distal end and the proximal end defining a body axis. The EMB connector also includes a load sensor connector for coupling with a load sensor disposed on the interior of the brake caliper assembly. The load sensor connector is compressible along a load sensor axis that is substantially perpendicular to the body axis. The EMB connector further includes a conductive component coupled to the load sensor connector. The conductive component enables electrical connection of the load sensor to the exterior of the brake caliper assembly.
