An electric conductor, in particular for connecting the starter relay and starter motor of a motor vehicle, includes an ignition device ( ), which is in thermal contact with the conductor ( ) and is intended, if a limit temperature is exceeded, for igniting and destroying the conductor ( ). The conductor ( ) includes one or more strands extending continuously between the ends ( ) of the conductor. The ignition device is disposed on the conductor ( ) so as to split apart these strands in the event of ignition.

Electrical conductor with an ignition device

A circuit arrangement for an engagement relay of a starter mechanism of an internal combustion engine, for bringing two gearwheels in engagement, the circuit arrangement having a switching element which reduces a relay current after a first time period before meshing of the two gear wheels to a determined current value during a second time period, the switching element being formed as a controlling and regulating device which increases a relay current to a predetermined value to a third time period which starts when one gear wheel reaches the other gear wheel.

Rectifier arrangement

In an apparatus for noise reduction and damping in ventilators of electric machines, in particular vehicular alternators, it is proposed that the ventilator support on the rotor shaft be effected by axially staggering inner rubber inlays on both sides and providing adjoining outer spring pressure elements such that the ventilator region is clamped, at least in the axial direction and preferably radially as well with an additional rubber ring. As a result, the transfer of resonant vibrations of the rotor to the ventilator are reliably avoided, and the noise emissions are decisively reduced.

Noise damped dynamo electric machine, especially vehicular type

To protect the space within which the slip rings (20a, 20 b) of a vehicular-type alternator operate, against extraneous contamination, a plastic sleeve (29) with an axially extending gap (35) is snap-connected with the inner wall defining an opening (28b) of a connection plate (23) already present in the alternator; this retains the sleeve (29), preferably of plastic, within the alternator, the other axial end thereof being secured to an internally extending projection from the B-end shield (15), either formed by a plastic bushing (19) surrounding the B-bearing (18) or an internal flange (36) already present on the end shield (15).

To facilitate assembly under mass production conditions, and to permit efficient cooling, a voltage regulator structure secured within a power transistor housing of the TO-5 shape as attached to a carrier plate which is narrower than the diameter of the housing, with a cooling sheet metal element interposed, bent over the carrier plate to be positioned within the cooling air stream of the automotive alternator, a carrier plate being preferably integral with the brush holder for the field current slip rings of the alternator. The brush holder-carrier plate combination is formed with attachment eyes on the carrier plate laterally of the voltage regulator, to attach the entire unit into an alternator and provide rugged and secure connection of the entire assembly to the remainder of the alternator structure.

Automotive-type voltage regulator and support assembly structure

An electrical connection system for alternating current rectifiers, particularly for use in alternating-current bridge-type rectifiers for motor vehicle generators, in which a portion of an electrical conductor embedded in a circuit board is cooled to a lesser extent than the remainder of the electrical conductor. The lesser cooled portion may have a smaller cross-sectional area than do the remaining portions of the electrical conductor. In the case of an overload on the connection system, the lesser cooled and/or smaller cross-section portion melts through.

Electrical connection system for rectifiers

In a rectifier in which button diodes are mounted in pairs as columns on bases which also constitute heat sinks, the connector connecting the diodes to the AC phase is made of a material which has high thermal and electrical conductivity. The columns are fastened to the base-heat sink by use of additional heat sink members which in turn are fastened to the base by bolts or screws. The latter are electrically insulating. The base-heat sink is star-shaped, the diode columns being mounted on the rays of the star. Preferably, the additional heat sink members have extensions which increase their effective cooling area.
