ABSTRACT:
A transformer comprising an outer coil former (1) having a first outer end portion (13), to which is secured a resilient device (49) which exerts a force on a first core part (47) directed towards a second outer end portion (15) of the outer coil former. Within the outer coil former (1) is arranged an inner coil former (3) having a first inner end portion (25), which is received by a recess in the first outer end portion (13) in a manner such that the resilient device engages only the first outer end portion and the first core part (47) but does not engage the first inner end portion. As a result, the resilient device not only holds the first core part in position, but also prevents the two coil formers (1,3) from moving away from each other.
