Definitions

  • the invention relates to a contact element made of stamped and rolled Sheet material with a contacting section, a conductor connection section and a fastening section for fastening the contact element in a receiving chamber of an insulating body.
  • Such contact elements are used to e.g. Currents in a vehicle electrical system, forward from a power source to the consumer.
  • This invention is therefore based on the object of a contact element train the type mentioned in that the transmission high currents is ensured and the heating of the contact elements and the fastening material is reduced to a minimum.
  • the insertion forces of the pin contact have a soft suspension during the initial insertion process and an increased spring force is present during the further plugging process, wherein the spring characteristic has a progressive course.
  • Components manufactured in this way also represent an inexpensive alternative to massive contact elements.
  • FIG. 1 shows a combined sectional and side view of two plugged-together contact elements, consisting of a pin contact 1 and a socket contact 2, each with an overlapping sleeve 3, which are inserted into their respective receiving housings 24 and 25.
  • Locking chambers 26 are provided in the receptacle housings, in which the contact elements are locked.
  • Electrical conductors 28 are attached to the contact elements, the contact element of the socket contact 2 being provided with a sealing sleeve 27 in order to protect this connection against contamination from outside.
  • FIG. 2 shows a side view of a contact element designed as a pin contact 1.
  • the contact element is divided into three areas: a contacting section 4, a fastening section 5 and a conductor connection section 6, the sleeve 3 being positioned above the fastening section 5, respectively.
  • the tubular fastening section 5 is provided with bores or recesses 7 in order to prevent rotation of the sleeve 3 on the fastening section, in which the hook-shaped, inwardly facing ends 17 of the spring tabs 15 engage there.
  • the contact tongues 9 of the contacting section are separated from one another by slots 10. It is provided that the slots 10 extend beyond the contacting section 4 into the fastening section 5. By the length of the slots, as by the shape of the contact tongues between the fastening section 5 and the constriction 8, the spring properties of the contact tongues can be varied and adapted to the desired requirements.
  • An electrical conductor is connected via crimp tabs 11 for the stripped strands, and with attachment tabs 12 for holding the cable sheath.
  • the contact element designed as a socket contact 2 is shown in a side view in FIG. 3.
  • the tubular contacting section 4 here simultaneously forms the fastening section 5 for the sleeve 3.
  • the conductor connection region 6, which is designed as a crimp connection for receiving and fastening an electrical cable.
  • bores 7 are also provided for the hook-shaped ends 17 of the spring tabs 15, which prevent the sleeve from rotating on the fastening section.
  • punchings 13 are provided on both sides of the fastening section, into which the locking tabs 21 and 22 of the sleeve 3 are bent, so that displacement of the sleeve in the axial direction is prevented.
  • FIG. 4 shows a side view of the sleeve 3 which has been punched from sheet metal and is bent in the form of a tube.
  • the sheet ends of the sleeve are bent inwards at the interface 14 in such a way that the interface, as a support web, ensures that the sleeve 3 is at a minimum distance from the fastening section 5.
  • spacer tabs 18 pointing inwards, as well as inwardly directed impressions 19 are provided as further spacer elements on the sleeve.
  • outwardly bent spring tabs 15 with inwardly facing hook-shaped ends 17 are machined out of the material of the sleeve.
  • the hook-shaped ends 17 engage in corresponding recesses 7 in the fastening section of the pin contact 1 or of the socket contact 2 and cause rotation in the radial direction.
  • the chamfers 16 of the spring tabs 15, which are bent almost at right angles, snap into the respective contact chamber 26 when the contact elements 1 and 2 are finally assembled in the receptacle housings 24 and 25, respectively.
  • the sleeve has a plurality of locking tabs 21 and 22 machined from the sheet metal jacket, with which the sleeve 3 is fixed in the axial direction on the fastening section of the pin and socket contact.
  • the contacting section 4 of the pin contact 1 to be inserted into the socket contact 2 is spherically shaped and provided with a slightly rounded but open tip, so that on the one hand an easy insertion of the pin contact into the socket is guaranteed, and on the other hand a secure contact even when the connector is angled is made possible.
  • the spring tabs 15 protruding from the sleeve 3 form with their bevels 16 locking elements, which when inserting the contact element, snap into the contact chamber 26 of the receiving housing and hold the contact element.
  • locking tabs 21 are on both sides of the sleeve end 22 for an axial locking of the sleeve on the fastening section of the Contact element provided.
  • FIG. 6 shows a modified pin contact 1 'without an overlapping sleeve 3 in a side view.
  • the contacting section 4 of the pin contact 1 'to be inserted into a socket contact is formed by the contact tongues 9, which are provided with outwardly directed contact embossments (32) and with a rounded tip, so that the pin contact can be easily inserted into the socket contact is guaranteed, as well as a secure contact is possible even with an oblique connection.
  • the spherically curved contact tongues 9, which are separated from one another by slots 10, have a shape in the front plug-in area that is curved toward the central axis of the pin contact.
  • the trapezoidal tips 30 of the contact tongues 9 are held laterally spaced apart. It is thereby achieved that the initial plugging process is facilitated by a soft suspension until the trapezoidal tips 30 touch, whereby an increased spring force is achieved during the further plugging process.
  • the initially soft spring characteristic of the contact tongues 9 fastened on one side in the tubular fastening section 5 merges into a progressive, steep spring characteristic.
  • the progressive spring characteristic is caused by the installation of the Contact tongues at their two end points, namely in the fastening section 5 as well as in the front plug-in area, due to the now touching trapezoidal tips 30, so that only a deformation in the area the crowned outward shaped and provided with raised embossments (32) Contact tongues 9 is possible.
  • Fig. 7 shows in an enlarged view how the center of the modified pin contact 1 'arranged concentrically, star-shaped mutually facing front ends 30 of the contact tongues 9, in the not plugged state are spaced (distance 31).
