Definitions

  • the invention relates to a plastic housing for electrical connectors according to the preamble of claim 1.
  • the plastic sheathing is not only intended to hold the two half-shells together mechanically, but above all to seal the connector against moisture penetration on the cable side, as is required, for example, when used outdoors or in the engine compartment of vehicles in order to ensure permanent, reliable function can.
  • Such a connector housing is already known from DE 37 26 515 C1. The problem of keeping the connector tight against the ingress of moisture between the cable entry socket and the cable cannot be solved to a sufficient degree even by several annular strain relief surveys that are pressed into the cable sheath.
  • the cable entry piece is separated into a contact-side part and a cable-side part connected to it via spacers, and the space is filled with the covering material.
  • This measure would also not result in a sufficient sealing effect if the spacers had a smooth surface. They are therefore provided with radially protruding ribs tapering towards the free end.
  • the required longitudinal watertightness can only be achieved through the "intimate assignment of the components involved" achieved, in which the plastic covering due to the shrinkage when cooling and the pointed edge parts of the ribs bear against them under high pressure.
  • the invention is therefore based on the object of developing a plastic housing in accordance with the preamble of claim 1 such that, in comparison with the prior art, an at least as high longitudinal water tightness between the cable inlet connection piece and the cable jacket is achieved in a more cost-effective and long-term reliable manner.
  • the melting temperature difference is about 30 ° C, at which a sufficiently fast melting thin spacers made of the material mentioned is possible.
  • this is of course also when using other materials achievable with other melting temperature differences, but the use of glass fiber reinforced plastic has the advantage of a particularly high mechanical stability, due to which the spacer webs can be made particularly thin; as a result, they melt so quickly at the above-mentioned melting temperature difference that the half-shells certainly cannot melt in an inadmissible manner.
  • a further advantageous embodiment of the plastic housing according to the invention is described in claim 4.
  • the injection nozzles are directed at those points of the spacer webs that melt fastest because the heat dissipation to neighboring housing parts (half shells) is lowest there. This achieves an absolute minimum of the melting time that can be achieved with given material properties and dimensions of the spacer webs. This provides the user with an additional means of optimally adapting the overall manufacture of the plastic housing in terms of dimensions and tolerances, the degree of melting of the half-shells, the choice of material (and ultimately also the tightness between the plastic sheathing and the cable sheath) and manufacturing reliability (reject rate) to the needs of the individual case .
  • the plastic housing of the electrical connector intended for use in the engine compartment of vehicles consists of a contact part (not shown) and a cable entry socket 1, in which a cable 2 is arranged in a form-fitting manner, which has three conductors 5 surrounded by a cable jacket 3 and each provided with an insulating sleeve 4 .
  • the cable entry socket 1 consists of two identical half-shells 6 which are connected to one another by a clip closure (not shown). On the inner surface of the half-shells 6, annular elevations 7 are arranged, which are pressed into the cable sheath 3 in order to achieve sufficient strain relief and rough longitudinal water tightness when the cable entry socket 1 is installed.
  • Each half-shell 6 consists of a cable-side part 8 and a contact-side part 11 spaced therefrom by a spacer 10 before the plastic housing 9 is encapsulated with a plastic sheath 9 13 on.
  • the plastic housing and thus the half-shell parts 8, 11 and spacer webs 10 are made by injection molding from glass fiber reinforced polyamide PA 6 (30% glass fiber content).
  • glass fiber reinforced polyamide PA 6 (30% glass fiber content).
  • this and the end region of the contact part facing it are extrusion-coated with a plastic covering 9 made of glass fiber reinforced polyamide PA 6.6 (25% glass fiber content).
  • the stability of the spacer webs 10 required for this is achieved on the one hand by the use of glass fiber reinforced material and on the other hand by a longitudinal profile with a W-shaped cross section.
  • the spacer webs 10 melt due to their small thickness - which was made possible with a glass fiber-reinforced polyamide contrary to a prejudice of the experts - and that of the material chosen Compared to the sheathing, the melting point is approximately 30 ° C lower, largely so quickly that the larger-volume half-shell parts 8, 11 melt only insignificantly.
  • the injection points are arranged at the level of the center of the web, that is, are directed to a point where the lowest heat outflow is possible, so that at least the central web area melts away with certainty.
