Definitions

  • the invention relates to a longitudinally watertight hose line provided for connection to a line connector according to the preamble of claim 1.
  • a hose line is known for example from DE 37 05 958 C1. So that the potting compound does not have to be refilled into the approximately vertically held insulating tube at any point until it solidifies, it is provided that the insulating tube is pressed together in a device at a certain distance from its free end and a fast-curing sealing compound (e.g. polyurethane foam) is first inserted into the free end part or silicone) and then insert the actual casting compound (e.g. casting resin). As a result, a smaller and precisely meterable amount of potting compound is necessary.
  • a fast-curing sealing compound e.g. polyurethane foam
  • the manufacturing effort is high due to the device required for this and the different sealing materials to be filled in, and the manufacturing time is relatively long due to the additional hardening time of the sealing compound, which in particular makes the series production of mass-produced products, which are involved here, considerably more expensive.
  • a stopper for the potting compound it is also known as a stopper for the potting compound to be filled in around the line wires before the final seating of the insulating tube at a certain distance from the free end of the line wires a plasticine-like mass (e.g. permanently elastic sealant based on synthetic rubber) or attach an insulating tape over which or that the insulating tube is then pulled forward until the required free end zone for the introduction of the sealing compound is formed.
  • a plasticine-like mass e.g. permanently elastic sealant based on synthetic rubber
  • attach an insulating tape over which or that the insulating tube is then pulled forward until the required free end zone for the introduction of the sealing compound is formed are also ensure that the sealing putty or the insulating tape really fills the entire cross-section of the insulating tube, so that potting compound can also pass through here.
  • these two processes are cumbersome and time-consuming and therefore not for series production suitable.
  • the potting temperature is so high that the sealing putty deforms and
  • the invention is therefore based on the object of developing a longitudinally watertight hose line according to the preamble of claim 1 such that a reliable seal is achieved in series production with little effort and a precisely metered small amount of potting compound and the line wires after the potting in their position associated plug contacts in the sense of short connections that are as free of crossings as possible.
  • Line connectors known from DE 37 26 515 C1 with a line surrounded by molded housing half-shells must have a rigid counter surface for receiving the spray pressure.
  • this counter surface is formed by the potting material, which, however, does not readily and always have the required cylindrical outer surface, which is required for the insulating tube to lie tightly against the inner half-shell surfaces. Due to its special design, the use according to the invention can optimally fulfill this additional function.
  • the multifunctional use ensures the longitudinal water tightness of the hose line, a quick and uncomplicated line wire connection and, at the same time, an advantageous usability for line connectors with half-shells lying under pressure on the insulating hose in an extremely simple and cost-effective manner, which is particularly suitable for mass production.
  • the line wires can be clipped into the grooves.
  • a corresponding length and the selected material of the insert have already achieved extensive clamping in the axial direction. It can be further increased by the fact that the contour of the holding area of the grooves is somewhat smaller in diameter than the outer diameter of the line wires. The advantage is thus achieved without additional effort that the insert certainly does not slip out of its desired position at a predetermined distance from the insulating tube end and the cable core end when the insulating tube is moved over the insert or when the potting compound is subsequently filled in.
  • the gap remaining between the cable cores and the insulating tube fills with casting compound over a length which essentially depends on their viscosity. This ensures the position of the insert and its cylindrical shape with certainty; Above all, however, a high level of tightness has already been achieved at this point, so that a relatively short plug-side filling with potting compound is sufficient to achieve absolute longitudinal water tightness. As a result, only a small amount of potting material is required in a cost-saving manner and, moreover, the length of the rigid region of the hose line is advantageously only short.
  • the insert can consist of a large number of materials - provided that they can withstand the melting temperature of the casting compound without deformation.
  • the insert according to claim 3 is particularly simple and inexpensive to manufacture (e.g. by injection molding), a wide range of materials being available with regard to an optimal adhesive effect.
  • the distribution of the grooves running in the longitudinal direction of the insert on its circumference can be uniform in individual cases. However, it is advantageous to adapt the mutual position (angular position) of the grooves to the position of the plug contacts with regard to the simplest possible assembly.
  • the hose line 1 consists of an insulating hose 2 and five insulated line wires 3 loosely arranged therein.
  • a cylindrical insert 4 made of plastic is introduced into its plug-side end area, the outer diameter of which is equal to the inner diameter of the insulating hose 2, and the five axially extending, evenly distributed on the circumference Grooves 5 each having an outer insertion area 6 and an inner holding area 7.
  • the width of the lead-in areas 6 is slightly smaller than the outside diameter of the line wires 3, the holding areas 7 are adapted in their contours to the cross-section of the line wires 3.
  • the five-pin angled connector 8 has a cover part 9 and a base part 10, which each consist of a line-side and a plug-side section.
  • the plug-side section of the bottom part 10 carries in a transverse wall 11 five plug contacts 12, to the soldered connection part 13 of which the stripped end 14 of a line wire 3 is connected.
  • the line-side sections of the cover part 9 and bottom part 10 are designed as half-shells, the end region containing the insert 4 of the hose line 1 and, in the assembled state, their inner surfaces are pressed firmly against the insulating hose 2 by an extrusion coating 15.
  • the line wires 3 are first deflected to their nominal size, stripped at the free end and clipped into the grooves 5 of the insert 4 at a distance corresponding to the connector dimensions, each line wire 3 being assigned to a specific groove 5 such that an intersection-free, space-saving continuation to the plug contacts 12 is given.
  • the holding areas 7 are advantageously dimensioned such that the line wires 3 are still easy to insert and, on the other hand, a slight clamping effect is achieved.
  • the insulating tube 2 is pushed so far over the insert 4 that it protrudes from the plug side by about 5-10 mm.
  • the webs 16 of the insert 4 located between the grooves 5 lie with their outer surfaces 17 against the inner wall of the insulating tube.
  • a filling 19 made of potting compound is introduced with the hose line 1 held approximately vertically, which, by appropriate choice of its viscosity, also partially in the insertion areas 6 of the grooves 5 between the line wires 3 and the inner surface of the insulating hose 2 remaining column penetrates.
  • the hose line 1 is successively inserted into the base part 10 of the angled connector 8, the stripped end of each line wire 3 is soldered to the solder connection part 13 of the associated plug contact 12 and the cover part 9 is placed on it.
  • Their half-shell-shaped sections lie closely against the insulating tube 2 along the filling 19 and the insert 4.
  • the encapsulation 15 is now applied, which holds the cover part 9 and the base part 10 together in a watertight manner, thereby also penetrating recesses 20 in the half-shell-shaped sections and, by welding to the insulating tube 2, forms a highly effective seal against the ingress of water between the insulating tube 2 and half-shells .
  • the longitudinal water tightness of the hose line 1 is achieved by the filling 19 with sealing compound. This can be precisely dosed by the insert 4 serving as a stopper and can be relatively thin.
  • the grooves 5 of the insert 4 additionally enable simple routing and assignment of the individual line wires 3 to the associated plug contacts 12 in a simple manner.
  • the insert 4 through the outer surfaces 17 of the webs 16, together with the potting compound penetrating into the gaps between the line wires 3 and the inner surface of the insulating tube 2, forms a solid cylindrical counter-surface which absorbs the pressure of the half-shells and, above all, the encapsulation which penetrates the recesses 20 15 picks up and the clean effect on the entire circumference enables the high sealing effect on the outer surface of the insulating tube 2.
