Abstract
An arrangement for transmitting electrical signals and/or energy between units mobile relative to each other, by means of galvanic contacts and a sliding-contact arrangement in particular. The inventive device excels itself by the provisions that at least one of said contacts comprises a basic material having a high mechanical stability, into which a second material is embedded which presents good electrical characteristics with respect to the transmission of electrical signals and/or energy, and that said second material is so distributed in said basic material that at least one further contact, which contacts this contact, is in contact with said second material along the major part of the trajectory of the movement.
Claims20
A system for transmitting electrical signals and/or energy between units mobile relative to each other through a sliding contact arrangement, the system comprising:
- a slideway comprising a first material, said slideway having a recess formed along a trajectory of movement and an insert having a width (I) and located in the recess;
- and
- a contact, which touches the slideway along a the trajectory of movement, said contact having a width (L);
- wherein said contact width (L) is greater than said insert width (I) such that said contact touches both said first and said second material as it move along the trajectory of movement and said second material electrically contacts said first material.
A system for transmitting electrical signals and/or energy between units mobile relative to each other through a sliding contact arrangement, the system comprising:
- a slideway comprising a first material, said first material having a recess formed along a trajectory of movement;
- an insert formed of a second material deposited in said recess, said insert having a width (I), where said second material has a lower electrical resistance than the first material and the first material has a higher mechanical hardness than the second material and wherein said second material electrically contacts said first material;
- a contact having a width (L);
- wherein said contact width (L) is greater than said insert width (I) such that the contact, which contacts the slideway along said trajectory of movement, touches said first and said second material along said trajectory of movement.
A system for transmitting electrical signals and/or energy between units mobile relative to each other through a sliding contact arrangement, the system comprising:
- a slideway;
- and
- a contact having a width (L) and comprising a first material, which contacts the slideway along a trajectory of movement, and a recess having a width (I) formed along the trajectory of movement, the recess having an insert located therein and comprising a second material;
- wherein said contact width (L) is greater than said insert width (I) such that said contact touches both said first and said second material as it moves along the trajectory of movement and said second material electrically contacts said first material.
A system for transmitting electrical signals and/or energy between units mobile relative to each other through a sliding contact arrangement, the system comprising:
- a slip-ring comprising a first material and having a recess formed therein along a trajectory of movement;
- an insert comprising a second material and located in the recess, said insert having a width (I) that is transverse to the trajectory of movement, and said insert comprises a second material that electrically contacts the first material;
- and
- a contact which contacts said slip-ring along the trajectory of movement, said contact having a width (L) transverse to the trajectory of movement;
- wherein said contact width (L) is greater than said insert width (I) such that said contact touches both said first and said second material as it moves along the trajectory of movement.
