Hybrid cable, method for its manufacture and use of such a hybrid cable
An electric lead contains at least three conductors. Each of conductors has a line which is surrounded by a conductor sheath. Two of the conductors are embodied as signal conductors, and form, with a common partial lead sheath surrounding them, a first partial lead, in particular a signal lead. Another of the conductors is embodied as a power conductor and forms a second partial lead, in particular a power lead. The conductors are surrounded by a separating sleeve, which is in turn surrounded by a common sheath of the electric lead. The lead is characterized in that the partial lead sheath has an inner sheath section and an outer sheath section, and the outer sheath section is harder than the inner sheath section.
1. A method for connecting sensors, which comprises the steps of:
providing an electric lead, the electric lead containing at least three conductors each having a line being surrounded by a conductor sheath, two of the conductors are signal conductors, a common partial lead sheath surrounding the signal conductors, the common partial lead sheath and the signal conductors forming a first partial lead, another of the conductors is a power conductor forming a second partial lead, the electric lead further having a separating sleeve surrounding the conductors and a common sheath surrounding the separating sleeve;
connecting the first partial lead as a signal lead to a wheel rotational speed sensor in a motor vehicle; and
connecting the second partial lead, as a power lead, to an electric brake actuator.
2. A method for manufacturing an electric lead, which comprises the steps of:
combining two conductors, via twisting, to form a first partial lead;
a partial lead sheath is applied jointly to the two conductors, the partial lead sheath having an inner sheath section being applied and subsequently an outer sheath section being applied, the outer sheath section is harder than the inner sheath section;
providing at least one other conductor which forms a second partial lead;
combining the first and second partial leads;
surrounding the first and second partial leads with a common separating sleeve; and
applying a common sheath to the common separating sleeve.
3. The method according to claim 2 , which further comprises combining the first and second partial leads by twisting.
