Definitions

  • the invention relates to a plug connector according to Claim 1 and a contact bushing according to Claim 21 and a contact bushing according to Claim 22.
  • An angled plug connector is known from WO 2012/023041 A1 , wherein a contact bushing is provided which has a circular cross-section, wherein an electrical contact, with a sleeve-shaped circular section, is inserted into the contact bushing, and wherein the sleeve-shaped section is connected to the cylindrical contact bushing in a mechanical and electrically conductive manner.
  • the problem of the proposed plug connector or proposed contact bushing consists in providing, with simple mounting and low mounting forces, a large pressing force and thus a great current conductivity between the contact bushing and the contact plug.
  • An advantage of the described plug connector or contact bushing consists in that the contact force between the contact bushing and the contact plug is increased at low mounting forces. This is achieved in that the contact surface of the contact bushing is not configured in a circle, but rather has at least two corners or recesses so that insertion of the contact plug is facilitated. By providing the corners or recesses, it is possible to displace material of the contact bushing to a greater extent and thus to achieve an increase in the contact surface and an increase in the contact force of the press contact between the contact bushing and the contact plug.
  • the recesses substantially have the shape of a corner in cross-section parallel to the contact opening.
  • the corner is formed by side surfaces which are adjacent one another in the corner.
  • This shape can be produced in the contact bushing with the aid of a punching method, for example.
  • tests have shown that, with the aid of this shape, a high pressing force is achieved with low mounting forces.
  • the current conductivity between the contact bushing and the contact plug is improved when this shape of the recesses is used.
  • the contact surface is formed by at least three side surfaces which are adjacent one another in predetermined corner regions at fixed angles.
  • the corner of the recess is disposed symmetrical to the circular line of the contact opening.
  • the contact opening is produced with the aid of a punching process.
  • the contact plug can also be manufactured in the form of a punched part. In this way, cost-effective production is made possible.
  • the contact bushing substantially has the shape of a plate, wherein adjacent to the contact opening there is configured a collar which represents at least a part of the contact surface. In this manner, the contact surface is enlarged using simple means, without having to use a thicker plate overall. As a result, material, construction space and weight are saved.
  • the collar can have further recesses. As a result, the flexibility of the collar sections can be adjusted.
  • the contact plug has a slot at least in a first contact section, which is inserted into the contact opening.
  • the slot is disposed along a longitudinal axis of the contact plug.
  • the slot can have a width perpendicular to the longitudinal axis of the contact plug, which can be in the region of 0.1 to 3 mm or greater.
  • the housing of the plug connector is configured in several parts, so that a simple mounting of the housing is possible.
  • the individual housing parts can be configured from different materials. The material can thus be optimally matched to the function of the housing part.
  • the further contact opening can, in cross-section, have the shape of a polygon.
  • the contact opening in cross-section can have the shape of a triangle, quadrilateral, decagon or hexadecagon.
  • the plug connector can have a circular or a polygonal, in particular a rectangular or square outer profile.
  • the contact bushing is manufactured by a folded plate, in particular a punched part. This therefore enables cost-effective manufacturing.
  • the contact plug has a first contact section and a second contact section, wherein the first contact section is provided for introduction into the contact opening of the contact bushing, wherein the first contact section in cross-section perpendicular to the longitudinal extension of the contact plug has a polygonal shape which is rounded in corner regions, in particular a rectangular shape, and wherein the second contact section has a cylindrical interior.
  • the plug connector is designed in the shape of a sleeve and has a continuous interior with an open front end, wherein the contact bushing has a contact surface, wherein the front end of the contact plug faces the contact surface, wherein the contact plug in particular has at least one side recess. It is possible to insert through the open front end a tool which acts on the contact surface and which can pull the contact plug off of the contact bushing.
  • the contact plug is manufactured from a punched part which is punched out of a plate and which has been bent into an appropriate shape, wherein side edges of the punched part abut one another at a contact line, the contact line in particular being configured perpendicular to a longitudinal extension of the sleeve-shaped contact plug. In this manner, a stable contact plug is supplied with the aid of a folded punched part.
  • the contact bushing has a connecting element for an electrical conductor, wherein the contact bushing has a contact opening, wherein the contact opening is delimited by a circumferential contact surface, wherein the contact surface has at least two corners, wherein the contact opening is provided for inserting the contact plug.
  • the contact bushing has a connecting element for an electrical conductor, wherein the contact bushing has a contact opening, wherein the contact opening has an inner contact surface delimiting the contact opening (61), wherein at least two recesses are produced in the circumferential contact surface, wherein the contact opening is provided for inserting the contact plug in order to configure a force-fitting connection between the contact plug and the contact surface of the contact bushing.
