Definitions

  • the present invention relates to a method for manufacturing a moisture-proof connection of an electrical Line with a thermistor of a temperature sensor according to the Preamble of claim 1.
  • JP-A-6 151 653 discloses a method according to the preamble of claim 1.
  • the present invention is based on the object simple and reliable process for making a moisture-proof connection of the type in question specify.
  • FIG. 1 is on emerging from a line wires 2 and 3 a thermistor 4 electrically and mechanically appropriate. This can be done, for example, by a temperature-resistant Solder connection, by welding or crimping the cable cores 2 and 3 with electrodes or not shown in detail Connections of the thermistor 4 take place.
  • the unit manufactured in this way from line 1 and thermistor 4 is introduced into an injection mold according to the invention and in Area of the line end and that located on it Thermistor 4 with a fixed on the cable jacket material and tightly adhering plastic 5, for example a thermoplastic, encapsulated in the manner shown. This creates at the end of the line in the area of thermistor 1 moisture-proof connection of the plastic 5 formed sensor head.
  • cable sheath material and sensor head material have the following materials, for example proven to be advantageous.
  • the cable sheath material is polyvenyl chloride, for example, polybutylene terephthalate is used as the sensor head material (PBT) suitable.
  • PBT sensor head material
  • the cable material based on polypropylene constructed is suitable as a sensor head material also polypropylene or high-pressure polyethylene.
  • FIG. 2 An embodiment one in such a two-stage The temperature sensor produced by the spraying process is shown in FIG. 2 shown in the same parts as in Figure 1 with the same Reference numerals are provided.
  • this embodiment is a second extrusion 7 via the first extrusion coating 5 intended.
  • 5 positioning elements 6 can be provided on the extrusion coating be in the injection mold for producing the Overmolding 5 can be injected directly.
