Definitions

  • the invention relates to a wire end sleeve according to the preamble of claim 1.
  • End sleeves of the generic type are known from DE 29 41 770 C2 or DE 33 14 295 Cl. Such wire end sleeves are used to produce solder-free electrical connections, the stripped end of a conductor being pressed or "verer_-in.pt" with the wire end sleeve using a Cri p tool. Such a crimping tool is shown, for example, in DE 26 14 577 B1.
  • Wire end sleeves consist of a front cylindrical metal tube or a metal sleeve with a molded or attached rear plastic collar as an insulating sleeve.
  • the stripped part of the fine-stranded conductor is inserted into the wire end sleeve from behind into the plastic collar and in the area of the metal sleeve squeezed, which creates the permanent connection.
  • the rear molded plastic collar receives the conductor with insulation as an insulating sleeve.
  • the different diameters and dimensions of wire end ferrules are specified in DIN 46 228 Part 4.
  • the cylindrical plastic collar and the front cylindrical metal tube are dimensioned such that only one conductor can be properly inserted and crimped at a time.
  • the wire end ferrule according to the invention with the characterizing features of claim 1 has the advantage that it is designed such that it easily accommodates two conductors without having to make a mechanical deformation of the plastic collar.
  • the invention is based on the knowledge that the cross-sectional ratios of the metal tube or the metal sleeve must be adapted in such a way that they each have a circular-cylindrical cross section, which can accommodate two twisted conductor ends, while the adjoining plastic collar has an oval cross section is dimensioned such that it can accommodate the two conductors lying side by side.
  • a geometric redesign of the wire end sleeves is required, d.
  • the circular cylindrical cross-section of the metal tube largely corresponds twice to the stripped conductor cross-section, while the cross-sectionally oval plastic collar must accommodate two adjacent conductors with their insulating sheath.
  • FIG. 1 is a plan view of the wire end sleeve in half cut shape
  • Fig. 2 is a plan view of the cross section of the plastic collar
  • FIG. 3 shows a side view of the wire end ferrule according to FIG. 1.
  • the wire end sleeve 1 shown in FIGS. 1 to 3 in a different view consists of a front cylindrical metal tube or a metal sleeve 2 with a front outer diameter and an inner diameter d2.
  • the cylindrical part of the metal sleeve 2 extends over a length 1-j and then opens to a conical section 3 with a cone angle C i ft 40 °.
  • the total length of the metal sleeve 2 is indicated by I2.
  • the outer diameter of the conical section 3 is denoted by d3.
  • the conical section 3 of the metal sleeve 2 is encapsulated by a plastic collar 4, which has a front conical section 5 and a rear cylindrical section 6 with the length I.
  • the total length of the plastic collar 4 is given as 1 ⁇ .
  • the plastic collar 4 starts from a length lg on the metal sleeve 2.
  • the total length of the wire end sleeve is indicated by lg.
  • the cone angle of the plastic collar is 4 0 ⁇ 2 ⁇ 5 °.
  • the inner lateral surface 7 of the cylindrical part 6 of the plastic collar 4 with the length I3 likewise runs slightly conically with a cone angle of 0 (3 3 °.
  • the plastic collar 4 has a front cone angle ( X ⁇ a_ 20 ° and an inner jacket cone angle ( 5 ft 5 °).
  • the conical section 3 of the metal sleeve 2 has the same cone angle 5 as the inner lateral surface 7 of the plastic collar 4.
  • the plastic collar 4 is provided with an oval shape, as can be seen in particular from FIG. 2 in a top view.
  • the wider side of the plastic collar 4 has an outer width b- j and an inner width b2.
  • This page is identified by reference number 8.
  • the narrower, circular segment-shaped side 9 of the plastic collar 4 has an outer width b3 and an inner width b ⁇ .
  • the wall thickness of the plastic collar 4 results from the difference between these widths.
  • the conical shape of the inner circumferential surface 7 of the plastic collar 4 leads to an inner width b ⁇ - as a longer and bg as a narrower inside length according to the length I.
  • the ferrule 1 serves to receive two conductors 10, 11, each of which has an inner conductor strand 12 and an insulating jacket 13 surrounding it.
  • the conductors 10, 11 have an outer diameter d ⁇
  • the conductor strands 12 have an outer diameter d 5 .
  • the wire end sleeve 1 is dimensioned with respect to its metal sleeve 2 such that the cross sections of the conductor strands 12 of both conductors 10, 11 can be easily inserted into the metal tube 2 after their stripping.
  • the inner cross section of the metal sleeve 2 must therefore be at least the sum of the two cross sections of the conductors 10, 11.
  • the inner width b2 at the end of the plastic collar 4 or in the front region 14 of the conical surface 7, that is to say about the length I must be dimensioned such that the two conductors 10, 11 can lie side by side with their outer diameter d ⁇ .
  • the widths ⁇ 2 and b ⁇ must therefore be approximately twice d ⁇ (see Figures 1 and 2).
  • the insulating jacket 13 is not pushed as far as the foremost region 14, 15 of the conical inner jacket surface (13), but is only pushed in up to a length l ⁇ . A sufficient insertion length of the insulating jacket 13 is decisive.
  • the ferrule is adapted to the geometric relationships of the conductors to be treated.
  • the invention is not restricted to the exemplary embodiment described and illustrated. Rather, it also encompasses all professional further training within the scope of the inventive idea.
  • a rectangular cross-section with a circular segment-like side boundary or the like can also be used.

Abstract

Il est proposé une douille d'extrémité de conducteur constituée d'une douille métallique (4) cylindrique (2) à l'avant et d'un collier en plastique injecté à l'arrière. Afin de pouvoir introduire simultanément deux conducteurs (10, 11) dans une douille d'extrémité de conducteur (1), la section intérieure du collier en plastique (4) est ovale et réalisée de manière à pouvoir recevoir deux conducteurs juxtaposés (10, 11).
