Definitions

  • the invention relates to a support for a contact element of a slip ring arrangement, in particular in a lock cylinder, with at least one slip ring on which at least one contact element is present.
  • Slip ring assemblies are always needed when electrical power or electrical signals must be transmitted between components that rotate relative to each other. Frequently, the arrangement is such that an elastic spring contact abrading the slip ring, so that the electrical contact is effected. Slip rings are often a weak point, especially in the transmission of signals, since even minor contamination disturb the clean contact of the contact and thus hinder the signal transmission.
  • a slip ring assembly for a lock cylinder in which a spring-mounted ball in a circumferential groove runs, in which the slip ring is arranged.
  • the ball can be stored either in the lock core or in the lock cylinder housing. Again, there is a risk that contamination hinder the proper contact of the ball.
  • the production and assembly and disassembly of the lock core is relatively complex, since the spring-mounted ball simultaneously how a locking element against axial withdrawal of the lock core acts.
  • the invention has for its object to form a slip ring assembly with a support of the type described improved.
  • the arrangement should be readily integrable in a lock cylinder.
  • the carrier has on its side facing the slip ring two spaced webs which extend parallel to the slip ring axis in the mounted position and define therebetween a parallel to the slip ring axis extending recess formed by at least one electrically conductive element is spanned, which is attached to at least one web and rests in the mounted position on the slip ring.
  • the electrically conductive element may, for example, be a wire which is secured at its opposite ends to the webs.
  • the wires used are relatively thin and, for example, a cross section of 0.05 mm 2 to 0.1 m 2 . It is a fine bundle of wires formed, which rests like a brush on the slip ring. It causes a cleaning effect that keeps the electrical contact surfaces clean. The operational safety is further increased.
  • the electrically conductive element may also be a leaf-shaped spring contact, which is at least attached to a web and is supported on the other web.
  • the slip ring will resiliently press the spring contact into the recess without the free end slipping off the web. A secure concern is also ensured hereby.
  • the spring contact can also be attached to both sides of the webs.
  • the webs are preferably part of a frame or insert, which consists of a non-conductive material. This has the advantage that the contact elements can be mounted more easily. It may further be provided that in the recess below the electrically conductive element, an elastic electrically non-conductive material is present. Thus, the contact elements can be supported over a large area. It can for example be used a foam which is pressed in the mounted position of the slip ring.
  • the webs are resiliently yielding. This allows the wires to be held under pretension. It is particularly advantageous if, in the mounted position, the circumference of the slip ring is partially immersed in the recess. Thus, a concern of the slip ring is achieved over a relatively large circle section.
  • a slip ring assembly with such a support for the contact elements is relatively small, especially since the often bulky springs can be dispensed with.
  • the slip ring can therefore be arranged on a locking core rotatable in the lock cylinder or a rotatable in the lock cylinder housing knob shaft of a shooting cylinder, the insert with at least one contact element in the cylinder sack of the lock cylinder housing can be mounted.
  • the cylinder bag is easily accessible from its side facing away from the lock core or the knob shaft. Also, there is sufficient space for the wearer, and he can be easily replaced there in case of wear.
  • a plurality of slip rings running parallel to each other in parallel may be present, which are separated from one another by circumferential projections. This has the advantage that the individual wire bundles are kept well in the track. Nevertheless, should a wire come loose, over-grip on an adjacent slip ring is prevented by the projection. The operation remains undisturbed.
  • the carrier 11 shown in FIG. 1 for contact elements has two parallel webs 12 which between them a Limit depression 14. In the assembled position, the webs and the recess parallel to the axis of the slip ring.
  • the carrier consists of an electrically non-conductive material, such as plastic.
  • the recess 14 is spanned by wires 15 which are attached to the tops 16 of the webs 12, 13, for example, glued or clamped.
  • wires 15 which are attached to the tops 16 of the webs 12, 13, for example, glued or clamped.
  • a contact element 13 which bears against the slip ring.
  • the illustrated carrier comprises three contact elements, as is often required in a combined power transmission and signal transmission.
  • the circumference of the slip ring 17 extends at least partially in the recess 14. As a result, the wires are stretched and safely abut the slip ring.
  • the webs 12 can be designed to be elastically yielding.
  • the slip ring 17 is arranged on a knob shaft 18 or a lock core, which is or is rotatably mounted in a lock cylinder housing 19.
  • the lock cylinder housing has for this purpose a cylindrical receptacle 20.
  • the cylindrical receptacle is followed in the conventional profile cylinders to a cylinder bag 21, in which the carrier is mounted.
  • the carrier 11 is held by a cap 22 on the lock cylinder housing.
  • the carrier is substantially H-shaped, wherein on one side of the web 23, the recess 14 and on the other side of the web, a space 24 is formed for cable.
  • Such an H-profile can be extruded. It then only has to be cut to length.
  • the arrangement of only one contact element or two or up to any number of contact elements is possible with appropriate length of the carrier.
