  • the DE 10 2005 003 269 A1 discloses a tubular electric heating element and a terminal assembly with which the electrode pads located on the outer peripheral surface of the heating element and electrically connected to a heat generating resistor body are electrically contacted.
  • the electrode pads are soldered to a metal connecting part, in which case a brazing material is used.
  • a soft solder can not be used at contact point temperatures above 300 to 500 ° C.
  • the heating element including the connecting part and the brazing alloy in an oven to a temperature of about 900 C is heated to burn the brazing, it is necessary to press the connecting parts at the moment of melting the solder against the electrode pads, so that a perfect soldering contact is achieved , This can be done only with relatively great effort.

  • the connecting parts are designed as massive cylindrical connecting parts.
  • connection arrangements for heating elements are known in which wires or strands with the connection contacts on the heating element by welding, in particular by an ultrasonic or similar method, get connected.
  • the mechanical strength of such a compound is usually insufficient and, moreover, its quality fluctuates greatly, so that such an approach is indeed suitable for small series, but unusable for mass production.
  • connection arrangements for electric heating elements provide no contact protection of the contact points and live parts to ensure the safety of the operating personnel, since the connection contacts and the associated metallic connecting parts or wires or strands are unprotected and uncovered.
  • connection arrangement for the electrical connection of electrically conductive connection contacts of an electrical heating conductor on a tubular electric heating element
  • the connection arrangement comprises at least two elongated metallic spring contacts and an electrically insulating base having a bottom and a top, wherein the top of the base for receiving one end of the tubular heating element is formed, and wherein the base between the bottom and the top at least one continuous, istströmmöbare opening and the base further comprises at least two recesses, wherein in each of the recesses each one of the at least two metallic spring contacts is fixed the recesses are arranged such that a first end of each of the spring contacts facing towards the top and showing a second end of each of the spring contacts in the direction of the bottom, wherein the first ends of the at least two spring contacts in the region of the top of the base are freely accessible.
  • connection contacts By “freely accessible” is meant that by inserting or inserting a heating element which has electrically conductive connection contacts on its outer circumferential surface, an electrical and mechanical contact between the connection contacts and the first ends of the spring contacts can be produced.
  • the erfindungeadore connection arrangement has the advantage that the metallic spring contacts are fixed mechanically fixed in the electrically insulating base and at the same time over its entire length of electrically insulating material, so that the base acts as protection against contact and reliably prevents accidental direct contact with live parts.

  • the heating element can be pulled out of the connection arrangement again and inserted again, so that a single heating element can be used several times in one or different connection arrangements.
  • the used connection arrangement is reusable. Accordingly, the terminal arrangement can be used for a plurality of heating elements and thus has a life expectancy which is significantly higher than that of a single heating element.
