Abstract: The invention relates to a method for current measurement in an in particular multiphase electrical system, in which an electrical load is energized as desired by at least one circuit element and a control unit produces drive signals which act on the at least one circuit element in order to achieve the desired energization of the load. The invention provides that clock patterns of the drive signals are associated with measurement windows for current measurement, in particular for measuring phase currents, and clock patterns are temporally offset in order to obtain measurement windows with a sufficient temporal length. A minimum temporal shift is the sum of a minimum dead time of the circuit element, a minimum settling time of the measuring amplifier circuit, and a minimum sampling time of the analogue-to-digital converter. The invention furthermore provides that the clock patterns are selected taking into consideration a phase selection for the current measurement.

Abstract: This connector has snap-fit lock including a partially deformable locking member which is mounted on the housing so as to be axially slideable between an extended locking position and a retracted position; and a biasing spring which axially bias said locking member to its locking position. The locking member has a flexible beam including a tooth member adapted to engage a complementary locking projection of the counterpart connector, and to provide an axial stop therewith. The flexible beam is elastically deflectable on the axial path of the locking member, whereby the snap-fit effect is provided by elastic load, both axial and in flexion, of the flexible beam.
