  • the cable retaining element has a primary part with an externally threaded portion, and that the through hole formed in the module housing is formed with a female thread corresponding to the male threaded portion of the primary part.
  • the primary part can be screwed with its male threaded portion into the internal thread of the through hole.
  • a sealing ring may be provided on the primary part.
  • the electrically insulating spacer element has outer dimensions which are slightly smaller than the clear cross-sectional dimensions of the through hole formed in the mounting housing, because it is then possible to insert the connection cable provided with the spacer element through the corresponding through hole in the module housing and with the cable contact element to connect the associated, provided in the power module module contact element safely and reliably. Subsequently, the cable retaining element is attached to the module housing, so that it is then no longer possible to pull the connection cable out of the module housing.
  • the spacer element is formed by a sleeve which is formed at its front portion with resilient latching fingers which are connected to an abutment of the cable contact element abut, wherein the sleeve rests with its rear end on the cable retaining element.
  • the abutment of the cable contact element may be formed by a circumferential groove or a circumferential shoulder, which is formed on the cable contact element. In the groove, a spring ring may be arranged.
  • the rear end of the sleeve-like spacer member may abut against the inner end face of the male threaded portion of the primary part of the cable fixing member. It is expedient if the rear end of the sleeve-like spacer element has outer dimensions which are adapted to the outer dimensions of the annular inner end face of the male threaded portion or slightly smaller than these.
  • the cable holding element can have a secondary part which can be screwed to the primary part and a clamping sleeve, and can be provided for a connecting cable which has a shield which is electrically insulated from the central cable core and an outer insulation.
  • the shield of the connection cable forms a closed EMC shield.
  • a strain relief of the connecting cable is achieved by such a design.
  • the cable connection device has through the electrically insulating spacer element between the cable contact element and the cable retaining element the advantages that a mechanical securing of the connector between the module contact element and the associated cable contact element is effected, that insulation creepage distances also under shock and vibration loads and movements on the connection cable be ensured, and that at the Forming the spacer element with resilient latching fingers assembly is made possible even after a crimping process, by means of which the cable core is firmly connected to the cable contact element.
  • FIG. 1 shows a design of the cable connection device 10 for a power module 12, of which the module housing 14 is drawn in sections.
  • the module housing 14 is formed with through holes 16.
  • the through holes 16 are formed as threaded holes, ie with an internal thread 18.
  • the reference numeral 20 denotes a module contact element, which is designed as a contact pin, which is screwed to a partially drawn load terminal 22 of the power module 12 and thus electrically connected firmly connected.
  • the module contact element 20 is contacted with a sleeve-type cable contact element 24, i. electrically connected, which is mechanically fixed, electrically conductively connected to a central cable core 26 of a partially drawn connection cable 28.
  • This connection can be a crimp connection.
