Definitions

  • the invention relates to a circular plug-in sleeve, in particular for watertight plug-in couplings, with a conductor connection part, an adjoining, sleeve-shaped bearing part and an adjoining the bearing part, sleeve-like contact part, which consists of connected to the bearing part and extending forward to a plug-in opening, for example spring arms arranged parallel and spaced apart.
  • EP-A-0 108 878 describes such a round plug-in sleeve with a conductor connection part (conductor claw area) which merges into a sleeve-shaped bearing part (cylindrical spring arm base part).
  • Three contact spring arms are connected to the bearing part and extend to the front at a lateral distance up to a plug-in opening.
  • the contact spring arms each have a crossbar in their free end region. These crossbars form a plug-in ring, the side edges of the crossbars being arranged opposite or abutting each other.
  • the known circular plug-in sleeve is not suitable for a watertight plug-in coupling, as is known, for example, from DE-A-33 02 924, since the plug-in ring, which consists of three subsections and is consequently not continuous, but is interrupted in the circumferential direction, also has a sharp-edged leading edge, sealing elements arranged here could be damaged when inserted into the chambers of the plug-in coupling provided for this purpose.
  • This known circular plug-in sleeve is additionally equipped with an over-spring which clasps the plug-in ring with a cylindrical over-spring ring.
  • the spring washer has a substantially continuous front edge projecting over the circular socket, which is, however, also relatively sharp-edged, so that the use of the spring does not make the known circular socket more suitable for watertight plug-in couplings.
  • the spring is a separately manufactured and to be assembled on the circular sleeve additional part, so that this known circular sleeve also requires a high manufacturing effort.
  • the invention is therefore based on the object, starting from this prior art, to provide a circular plug-in sleeve which has no sharp edges, but nevertheless requires little work to produce it.
  • a collar is connected to the plug-opening end of the spring arms as a material band extending transversely to the spring arms and turned outward tightly to form a rounded front edge surrounding the plug-in opening to the plug-side end region of the spring arms.
  • the round plug-in sleeve according to the invention has no sharp edges, particularly in the region of the plug-in opening, even without an additional spring, so that it is particularly well suited for use in watertight plug-in couplings, with damage to the sealing elements advantageously being excluded.
  • the production of the circular receptacle according to the invention is very simple, since, starting from a single-piece stamped-out circuit board, the material band forming the collar only needs to be turned over by 180 °. The board is then rolled in such a way that the abutting edges of the collar on the one hand and of the bearing part on the other hand abut each other, so that sharp edges are advantageously avoided in this area as well.
  • an additional spring is provided, but this spring sits between the bearing part and the collar in the area of the spring arms.
  • the conductor connection part 1 to 4 mainly consists of the conductor connection part 1, which has a conductor wire claw as shown or another known connection element for e.g. the clamping cutting or soldering technique can be.
  • the round bearing sleeve 3 adjoins a transition region 2 which is bent in a U-shaped cross section.
  • tabs 4a are expediently introduced through incisions 5 oriented parallel to the longitudinal axis 4 of the circular plug-in sleeve, which are curved outwards and produce a plug-limiting edge in a manner known per se.
  • the bearing sleeve 3 forms a spring arm base for spring arms 7 connected to it and extending forwards to the plug opening 6, approximately parallel and spaced apart, the spring arms 7 forming the contact sleeve 8 of the circular plug-in sleeve.
  • the spring arms 7 result from elongated holes 9 cut out of the circuit board (FIG. 1), the length of which corresponds to the length of the spring arms 7.
  • the elongated holes 9 can be bottle-shaped or oval as shown.
  • the collar 10 is a transverse to the longitudinal axis 4 extending material band tied. The width of the collar 10, ie its axial extent is - as shown - about 1/4 the length of the spring arms 7.
  • the collar 10 is bent outwards and struck tightly onto the end regions of the spring arms 7 on the insertion opening side.
  • the bending line 11 is arranged such that no sharp edges occur in the insertion opening 6 (Fig. 3).
  • the board is rolled such that the abutting edges 12 of the collar 10 and the bearing sleeve 3 abut each other.
  • the associated rolling work is very low because the area of the spring arms 7 can deflect radially inwards and in the process does not offer any appreciable resistance and the collar 10 can be rolled in without material distortion until the abutting edges 12 meet.
  • the spring arms 7 taper towards one another slightly, so that the outer diameter of the collar 10 corresponds to the outer diameter of the bearing sleeve 3 and, accordingly, their lateral surfaces are axially aligned with one another.
  • the spring arms 7 are bent inwards towards the longitudinal axis 4 and also slightly inwards transversely thereto, so that they are convex at these contact points 13 towards the interior and each have a punctiform contact for the dash-dotted line in FIG. 3 ensure indicated pin 14 and thus a defined contact point.
  • This deflection is advantageously in the direction of the bearing sleeve 3 just behind the collar 10, so that the contact points 13 are as far as possible in the front in the region of the plug opening 6.
  • the invention provides a circular plug-in sleeve with the desired soft spring characteristics, caused by relatively long spring arms, connected to a defined contact point.
  • the collar ensures the necessary stiffness and stiffening for insertion into a chamber of the plug-in coupling and also a desired stiffening of the spring arms in the manner of a spring. The forces required to manufacture the circular receptacle from the board are extremely low.
  • the circular receptacle according to the invention can be easily equipped with an over-spring 14a, so that a relatively soft, more easily deformable, electrically highly conductive metal can be used as the material for the circular receptacle.
  • the spring 14a e.g. made of steel strengthens or optimizes the spring forces in this case.
  • the over-spring 14a extends from the connection point of the spring arms 7 to the collar 10 and in the simplest case consists of a round cylindrical sleeve which sits on the contact sleeve 8 of the circular plug-in sleeve, the spring arms 7 immediately behind their connection to the bearing sleeve 3 by e.g.
  • the over-spring 14a finds its other abutment on the lower edge 16 of the collar 10. Since the material of the over-spring 14a is thinner than the material of the circular plug-in sleeve in the area of the contact sleeve 8, the over-spring 14a does not bulge and does not interfere.
  • At least one detent spring arm 17 is preferably provided on the over-spring 14a, which is cut free from the jacket of the sleeve of the over-spring 14a and extends obliquely outwards from the collar-side end region to the bearing sleeve 3, the base region 18 of the over-spring 14a to which the detent spring arm 17 is connected, is appropriately penetrated bead-like to the outside.
  • the bead 18a does not protrude beyond the jacket surface of the collar 10 or the bearing sleeve 3 and the abutment edge 15 protrudes so far inward that the detent spring arm 17 finds sufficient space so that it can move into this space if the circular sleeve into a chamber of a plug coupling is inserted.
  • a plurality of detent spring arms 17a are integrally connected to the collar 10.
  • the locking spring arms 17a are provided as spring arms 7, the locking spring arms 17a being arranged practically in the extension of the spring arms 7 (FIG. 5).
  • the detent spring arms 17a are designed to be somewhat shorter than the spring arms 7 and the spring arms 7 have in their connection area a penetration 19 by at least one material thickness inwards, so that the detent spring arms 17a can also radially deflect as far as the circular plug-in sleeve is inserted into a chamber of the plug-in coupling, that they do not survive and thus can not cause damage to the sealing elements of the chamber.
