Measuring and/or checking system including at least two units, and method to connect such units

Abstract

A measuring and/or control system (), to control for example a machine tool, comprises at least a first and a second unit, each comprising electronic circuits and at least one socket. The systems further includes a multipolar cable () containing a plurality of wires (A) and having a first and a second end, each provided with a multipolar connector () adapted to be coupled to a socket of the first unit and second unit. At least one of the multipolar connectors of the multipolar cable is a fast wiring multipolar connector () provided with a first body (A) and a second body (B), adapted to be plugged into the first body. The first body comprises a support with two opposite faces, a first group of electrical contacts fixed to one of the faces of the support and adapted to be coupled to one of the sockets of the first or second unit, and a second group of electrical contacts fixed to the other face of the support. The second body comprises a frame with a plurality of seats (S), a plurality of perforating electrical contacts (P) that are adapted to be coupled to the second group of contacts of the first group, are housed in the seats, and are configured to perforate an insulating sheath which covers the wires (A) and to fasten and electrically connect the wires and the perforating electrical contacts to each other, and a plurality of movable elements (D) coupled to the frame and adapted to cooperate, in the seats, with the wires housed in the multipolar cable () in order to fasten and electrically connect the wires (A) and the perforating electrical contacts (P) to each other.
