Definitions

  • the invention relates to an electrical contact between a connecting pin and a connecting wire to be connected according to the preamble of claim 1 and to a method for producing an electrical connection between a connecting pin and a connecting wire according to claim 11.
  • the invention is based on the object of providing an electrically conductive connection between a connecting pin and a connecting wire with simple measures and without supplying heat.
  • the electrically conductive connection between the connecting pin and the connecting wire which is provided with an electrical insulation, in that the connecting wire including insulating jacket, so without removing the insulation, is wound around the connecting pin, which is an edge has, so that the wire winding is applied directly to this edge.
  • a Anpressteil is provided, which surrounds the connecting pin in the region of the wire winding and exerts a radial contact force on the wire winding, wherein the radial contact pressure is directed inwardly in the direction of the connecting pin.
  • the wire winding is acted upon by a radially outwardly inwardly directed contact force and pressed against the edge on the outer jacket of the connecting pin, whereby the insulating jacket injured and the conductive core in the wire comes into direct contact with the conductive pin.
  • a cold welding between the wire and the lateral surface of the pin in the region of the contact points is achieved due to the continuing, high contact pressure.
  • a sufficiently high contact normal force is generated by the pressing part, which ensures the electrically conductive contact between the wire and the pin.
  • a second aspect of the invention which relates to the method for producing the electrically conductive connection, first the connecting wire including the electrical insulating jacket is wound around the edge on the connecting pin, then the pressing part is placed around the wire winding on the connecting pin and it is about this Anpressteil a generated radially in the direction of the pin acting pressing force.
  • This is done according to an advantageous embodiment in such a way that the pressing part is pushed axially onto the connecting pin, wherein already during the pushing on the wire winding can be pressed radially against the connecting pin.
  • the cutting of the insulating jacket on the connecting wire is carried out solely on the basis of the static pressure which is exerted in the radial direction by the pressing part.
  • the Anpressteil executed in such a way that with the pushing of the pressing already the radial pressure is exerted expediently at least a portion of the Anpressteils, which is preferably designed as a sleeve, an inner diameter which is less than at least a portion of the order Pin laid wire winding, so that already by pushing on the pressure sleeve, the radial contact force is generated.
  • Another alternative is a longitudinally slotted sleeve into consideration, which can be opened radially due to their spring action and then exerts a radially inwardly directed pressure.
  • the Anpressteil is also cup-shaped, i. it is provided a bottom which limits the pushing of the pressing on the front side of the pin.
  • the pressing part may also be expedient to carry out the pressing part with a diameter larger than the wire winding and postpone it onto the pin with the wire winding. Only after the pressing part has reached the desired axial position, this is pressed mechanically and thereby pressed radially against the wire winding.
  • Fig. 1 is a view of a terminal pin, which is wrapped with a lead wire, which is to be electrically connected to the pin, wherein a sleeve-shaped pressing member is pressed end face on the pin, whereby the wire winding is pressed radially against the edges of the square in cross-section pin .
  • Fig. 2 is a section through the pin including wire winding and attached Anpressteil.
  • a pin 1 which consists of electrically conductive material and is part of an electrical component 2, for example, a winding support or the like and electrically connected to a lead wire 3 is connected, which branches off from a coil winding, not shown.
  • the electrical connection wire 3 is placed including its insulating jacket around the lateral surface of the connecting pin 1 and forms a wire winding 4.
  • the connecting pin 1 has a rectangular, in particular a square cross section and has a total of four sharp edges 5, against which the core of the connecting wire 3 rests in electrically conductive contact.
  • This electrical contact is made by mechanical joining.
  • a sleeve-shaped and conically shaped Anpressteil 6 is axially mounted on the end face of the connecting pin 1 under pressure or train. During the axial pushing on the Anpress presses 6 this exerts due to its cone shape an increasing, radially inwardly directed contact pressure on the wire winding 4, so that it is pressed against the outer surface and in particular against the edges 5 of the connecting pin.
  • the connecting wire 3 has an insulating jacket 7, which is expediently designed as an insulating lacquer layer in coil wire and is injured or severed by the radial contact pressure in the region of the relatively sharp edges 5.
  • the contact pressure generated by the Anpressteil 6 is high enough that the insulating jacket 7 is severed and the edges 5 protrude into the core of the lead wire 3. Due to the ongoing pressure generated by the Anpressteil 6 is formed between the edges 5 of the pin 1 and the core of the lead wire 3, a permanent electrical connection.
  • the axial displacement of the wire winding 4 along the lateral surface of the connecting pin 1 may be limited by a stop on the connecting pin, for example a circumferential shoulder or the like.
  • a sleeve can be provided with a longitudinal slot.
  • the advantage of the slotted sleeve is that the sleeve can exert a radial compressive force over a greater range of internal diameters than an unslotted sleeve because the slotted sleeve has lower rigidity. However, the maximum radial compressive force is greater in the non-slotted sleeve.
  • the slotted sleeve is bent in the resilient portion, loosely slipped over the wire coil and then partially relaxed so that the sleeve radially presses the wire onto the edges of the terminal pin.
  • the methods described for the non-slotted sleeve for making the electrical contact are also applicable to the slotted sleeve.
  • the dimensioning and the shape of the Anpress presses 6 is chosen so that they produce without a radial contact force on the pin including the wire winding. 4 can be deferred.
  • the radial contact force is achieved only after reaching the final axial position in that the pressing member 6 is mechanically compressed and pressed against the pin and the wire winding 4.

Abstract

L'objectif de cette invention est de produire un contact électrique entre une broche de connexion et un fil de connexion. A cet effet, la broche comporte une arête contre laquelle le fil ainsi que la gaine isolante recouvrant ce fil sont comprimés radialement. La force de compression radiale est générée par l'intermédiaire d'une pièce de compression qui entoure la broche de connexion.
