Definitions

  • the invention relates to a plug-in sleeve for a plug connection between two electrical line sections and a method for producing such a plug-in socket.
  • Plug connections for connecting two line sections are usually realized by clamping action by means of plug sockets.
  • the production of the sockets is done so far by machining methods such as turning or milling on a CNC machine and the subsequent manual processing of the sockets by sections plastic deformation.
  • a disadvantage of the known connectors is in particular that the production of the receptacles is complicated and error-prone by manual processing steps, so that come to the high production costs and high reject rates.
  • the US-A-1 433 878 discloses a collet having a body portion and an elastic tension portion.
  • the body portion substantially forms a cylinder with a bore passing therethrough.
  • the body portion is followed by a portion which is formed with fingers, and which is adaptable in shape to a desired cross-sectional shape, such. As an oval shape, a hexagonal shape or a rectangular shape.
  • the finger portions continue to form a frusto-conical portion of a cone.
  • Object of the present invention is therefore to provide a connector which a secure, easy and inexpensive to manufacture connection between the to be connected to line sections, and to specify a corresponding method for their production.
  • Fig. 1A and 1B show in highly schematic, partially sectioned views an embodiment of a receptacle 1 for the detachable connection of two line sections 2, in particular for electrical connections such as coaxial cable, in two different stages of processing.
  • the matching second line section 2 is in Fig. 1A and 1B not shown.
  • the receptacle 1 is thereby manufactured and processed in order to fulfill its holding function by removing from a blank, for example using a CNC machine for machining such. Turning or milling, a cylindrical socket 1 is formed and provided with a likewise cylindrical blind hole-like recess 3.
  • slots 4 are introduced into the region of the socket 1, in which also the recess 3 is formed.
  • the number of slots 4 should be at least two for reasons of reliability in the clamping effect, four slots 4, which intersect, for example, cross-shaped, however, are even more advantageous.
  • the Slots 4 have over their axial length a constant width, ie edges 6 of the slots 4 are each equidistant from each other over the axial length.
  • the plug-in sleeve 1 After the preparatory machining, the plug-in sleeve 1 thus has in the region of the recess 3 a plurality of wall sections 5 separated by the slots 4, which have a more or less strong elasticity depending on the material thickness of the wall of the plug-in sleeve 1.
  • the wall sections 5 are formed by manual plastic deformation slightly radially inward in the prior art, whereby the receptacle 1 in the slotted area receives a slightly conical shape.
  • the edges 6 of the slots 4 are thereby, as in Fig. 1B shown in sections brought to shock, whereby the slots 4 receive a triangular shape.
  • the previously described method for producing the plug-in sleeve 1 as a combination of machining and plastically deforming machining steps has several disadvantages.
  • the reproducibility is not satisfactory, since even small offsets can lead to larger differences in the final shape of the receptacle 1.
  • the process is time-consuming and labor-intensive and thus cost-intensive.
  • the plug-in sleeve 1 both in its outer shape and in the shape of the recess 3 formed in it at least partially tapered exclusively by machining processes without plastic, manually performed process steps.
  • FIG Fig. 2A A first exemplary embodiment of a plug-in sleeve 1 designed according to the invention is shown in FIG Fig. 2A shown schematically.
  • the socket 1 is conically shaped at least in the region comprising the wall sections 5, in particular in the region of the slots 4.
  • the blind hole-like recess 3 in the interior of the socket 1 is also at least partially conical, in particular in the region of the slots 4 that the wall of the plug-in sleeve 1 in the region of the slots 4 has a uniform wall thickness.
  • An opening width A of the recess 3 of the receptacle 1 can in particular be at least 0.6 mm, a bore length B of the recess 3 in particular 0.6 mm to 1.5 mm, wherein the bore length B may be five times the opening width A.
  • the reduction C of the diameter of the recess 3 in the conical region is at a diameter of the recess 3 between 0.6 mm and 1.0 mm approximately 0.08 mm, with a diameter of the recess 3 between 1.0 mm and 2.0 mm approximately 0, 1mm, with a diameter of the recess 3 between 2.0mm and 4.0mm about 0.2mm and at a diameter of the recess 3 between 4.0mm and 5.0mm about 0.3mm.
  • the axial length E of the conical region corresponds at most to the bore length B of the recess 3.
  • the slot width F is at least 0.06 mm.
  • a first outer diameter D A, 1 of the receptacle 1 is greater than a second outer diameter D A, 2 of the receptacle 1, wherein the receptacle 1 tapers in the direction of the region in which the recess 3 is introduced. Accordingly, an inner diameter of the blind hole-like recess 3 at the closed end of the recess 3 is greater than at the open end of the recess 3, so that the conical taper of the recess 3 is the same and in magnitude equal to the taper of the outer diameter D A of the receptacle 1.
  • the slots 4 thereby retain in the unloaded state their constant slot width with uniform spacing of the edges 6 of the slots 4 so that no failures occur due to uneven shock areas or overlaps of the wall sections 5 with subsequent damage to the receptacle 1, while in the loaded state, if a counterpart the line sections 2 is inserted into the recess 3, sections are widened. With a suitable choice of the outer and inner diameter of the pipe sections 2, a smooth surface is nevertheless ensured.
  • the socket 1 in the embodiment, a shoulder 7, which allows easier handling of the receptacle 1 when placed on the line section 2.
  • Fig. 2B shows a second embodiment of an inventively designed socket 1, which has at a front end 8 of the recess 3 a circumferential locking bead 9.
