Definitions

  • the invention relates to a press sleeve for producing a press connection with one strand, in particular an electrical conductor.
  • a compression cable lug which has a compression sleeve has which is provided on its inner surface with a thread.
  • the thread is produced by forming a helical, groove-like Depression formed without cutting.
  • the thread is said to be a good mechanical and electrical Connection between the press sleeve and the strand to be picked up guarantee.
  • this press sleeve as well the known compression sleeves with a smooth inner surface are not always closed leads completely satisfactory press connections.
  • the invention is therefore based on the object, a compression sleeve of the beginning to improve the type mentioned. This object is achieved by a Press sleeve with the features of claim 1.
  • the groove-like depressions in the longitudinal direction of the sleeve define weak points in the sleeve wall. At these defined weak points, the sleeve wall deforms in such a way that longitudinal cuts are formed. Furthermore, due to the weak points, the restoring force of the press sleeve opposing the pressing is reduced. As a result, a lower pressing force is sufficient to achieve a press connection of the same quality. In addition, the better compressibility enables a shorter length of the compression sleeve and thus possibly a smaller, in particular shorter sleeve with a correspondingly lower need for cast resin. A shorter press sleeve also requires fewer press points.
  • the number of pressing points in the circumferential direction (usually six) deviates from the number of groove-like depressions (for example eight).
  • the press sleeve according to the invention it is also possible to firmly and electrically connect a single-wire to a multi-wire conductor, even if the two conductors each have the same cross-sectional area but different outer diameters and the inner diameter of the press sleeve is constant over its entire length.
  • the groove-like depressions as continuous longitudinal grooves are formed and evenly in the circumferential direction are distributed.
  • the latter is also for the quality of the connection advantageous.
  • Very advantageous are groove-like depressions, the flanks of each one Form edge with the inner surface, especially groove-like Depressions that are rectangular or trapezoidal Have cross-sectional profile.
  • the compression sleeve has cut on their inner lateral surface, which is aligned with a Component extend in the circumferential direction and advantageously Parts of one interrupted by the groove-like depressions Threads.
  • the embodiment is in one piece trained, approximately hollow cylindrical press connector, the two identical press sleeves 1 according to the invention axially next to one another having.
  • Each press sleeve 1 has cutting edges 3 on its inner lateral surface on which run essentially in the circumferential direction and in the manufacture of the compression sleeve 1 as parts of a thread 2 were formed, preferably by non-cutting shaping.
  • By the inward-facing edges of the cutting edges 3 is the inside diameter the compression sleeve 1 defined.
  • this edge of the cutting 3 to the outer surface of the press sleeve 1 out the wall thickness of the compression sleeve 1 is defined.
  • the compression sleeve 1 also has on the inner jacket side their entire length of axially extending, groove-like depressions 5 on, the flanks of which each have a longitudinal edge with the inner shell side 5 'form.
  • six are the same groove-like Wells 5 evenly in the circumferential direction of the compression sleeve 1 distributed. Through the groove-like depressions 5 in these areas, the wall thickness of the compression sleeve 1 is reduced.
  • the groove-like depressions 5 are as Longitudinal grooves formed with a rectangular cross section; however, a trapezoidal or round cross section could also be used Find application. The production of the groove-like depressions 5 can be made without cutting or cutting.
  • the compression sleeve 1 carries several on its outer surface Markings 7 for attaching the press tool, through which ring zones experiencing compression are defined.
  • the groove-like depressions 5 are exemplary embodiments consistently over the entire length of the compression sleeve 1 with the provided the same cross section, but it would for the invention Formation of longitudinal cuts is sufficient if the groove-like depressions 5 essentially in the area of the markings 7 defined ring zones would be formed.
  • the two compression sleeves 1 designed so that they have a common Outer surface, the same inner diameter that Cut 3 as parts of the same thread and over both Press sleeves 1, the continuous groove-like depressions 5 have.
  • the Press connector In the middle area of the press connector, in which the two press sleeves 1 merge into, the Press connector one from the inner surface to the outer surface reaching hole 9.
  • the compression sleeves 1 are on the end faces the compression sleeves 1 chamfered to the inner surface to the To facilitate insertion of a conductor strand.
  • a Press connector with two press sleeves according to the invention also two Have blind holes so that the compression sleeves through a central wall are separated.
  • the inside diameter of the Blind holes or parts of the hollow cylinder different be, the press connector so be a reducing connector.
  • press sleeve according to the invention could also be part of a Press cable lug.
  • ferrule is not on electrical conductors limited. It can also be used to manufacture a mechanical Connection with any strands can be used.
  • Press sleeve 1 To produce a press connection by means of an inventive Press sleeve 1 is usually first the to be pressed, Insulation-free conductor in the greased with press grease Press sleeve 1 introduced. Then get on through the markings 7 marked positions one after the other a press tool, for example, a pressing tongs, attached and in the press the corresponding sleeve zone with a force, the to a predetermined pressing force between the Press sleeve 1 and the conductor inserted into it.
  • a press tool for example, a pressing tongs
  • the sleeve wall deforms these weak points in the respective ring zone such that the longitudinal edges 5 'of the recesses 5 to themselves in the longitudinal direction of the sleeve extending longitudinal cutting.
  • the groove-like depressions 5 also have after pressing an albeit reduced free cross section. Meals how in the exemplary embodiment, such a recess 5 in at least one of the end faces of the compression sleeve 1 or at the hole 9, so They thus become a pressure relief channel for the press grease. If the press grease heats up, it can then flow through these pressure relief channels expand. This can prevent a pressure builds up in the press sleeve, which leads to an expansion the press sleeve could lead.
