Definitions

  • the invention relates to a fork-shaped contact element, in particular a flat contact element stamped from sheet metal material, the contact forks being characterized by a forward, ie. H. towards the insertion end of a contact pin, an open slot is formed and contact is made with the contact pin in the front area of the slot or the contact forks.
  • Such contact elements are usually mass-produced from a strip-shaped sheet metal material, the contours of the contact elements being punched out by means of a stamping process. For further processing such.
  • B. surface treatment or insertion of a group of contact elements in an insulating body of a connector can be provided that the contact elements initially remain connected to an upper and lower tether.
  • the contact elements are separated by separating the holding strip or strips.
  • the contact properties of such contact elements ie the contact pressure of the contacting areas of the contact arms on a contact pin inserted into the contact element, are in addition to the width of the contact arms / contact forks also significantly influenced by the length of the contact arms, ie the depth of the slot forming them.
  • this slot In order to produce a certain contact pressure of the contact arms, this slot must therefore only have a very specific depth. Problems often arise in practice in that the contact pins of a mating connector, in particular if connectors with leading contact pins are to be used, are longer than the depth of the slot allows and then open the contact pins in the bottom of the slot, so that a perfect contact is not always guaranteed for the "lagging" contact pins.
  • the invention is based on the object of forming a contact element of the type mentioned in such a way that the possible insertion depth of a contact pin is independent of the depth of the slot in the contact element and that the contacting properties (contact pressure) of the contact arms of the contact elements are independent of the length of the contact pins to be inserted can be trained.
  • This object is achieved in that a region of the contact element adjoining the contacting region is bent / arranged laterally offset, by an amount which corresponds to at least the radius of a contact pin to be inserted, the length of this region being adapted to the length of the longest contact pin to be inserted.
  • the advantages achieved by the invention consist in particular in that the region of the contact element which is laterally offset from the contacting region prevents the contact pins inserted into the contact element from striking the bottom of the slot forming the contact arms. This makes the formation of the spring properties of the contact arms and thus the required length / depth of the slot independent of the insertion depth of the contact pins.
  • the contact arms have the tendency due to the lateral bend not to spring apart when bending apart, i.e. when inserting a contact pin, parallel to each other (with respect to the opposite contact surfaces), but at a small angle, so that the contacting ultimately only over an edge region of the contact arms.
  • This effect can possibly be increased if the contact arms are deliberately bent out of their parallelism at a small angle during the manufacturing process.
  • the contact surface On the entry side of the punch, the contact surface has optimal smoothness, and by springing open the contact arms at a small angle, the contact with the contact pin essentially occurs on this edge area, and wear of the contact pins becomes frequent with frequent insertion and removal largely counteracted.
  • the contact element shown in FIGS. 1 and 2 is designed as a fork-shaped contact element and punched out of a flat sheet metal material.
  • the contact element has two contact arms 1, which are separated from one another by a slot 2.
  • inward-facing contacting areas 3 are provided, which produce the electrical connection with a contact pin 4, which is indicated in FIG. 2 when the latter is inserted.
  • the contact element is provided in its lower area with a mounting area 5 for mounting in an insulating body and a pin-shaped end 6 for connection to a printed circuit board.
  • the area 7 adjoining the contacting area is bent laterally offset to the plane A of the actual contact element, namely by an amount B which corresponds at least to the radius of the contact pin 4. This offset ensures that an inserted contact pin can be pushed freely next to the inner side 8 of the offset area and does not hit the bottom 9 of the slot 2.
  • FIG. 3 shows an enlarged section through the contact area 3 of the contact element, an inserted contact pin 4 being indicated.
  • the punching direction is shown by the arrow S in which the punching tool was moved during the manufacturing process of the contact element.
  • the front Edges 10 of the contact area were produced with a very smooth surface, while the rear edges 11 have a tip pointing in the punching direction and the area in front of these edges has a relatively large roughness.
  • the contacting surfaces 12 of the contact arms or of the contacting region 3 are displaced at a small angle ⁇ to the central axis X of the contact element.
  • the contacting between the contact element and the contact pin takes place predominantly between the front, smooth surface or edge 10 of the contacting area and not in the rear, relatively rough area in front of the edge 11.
  • the angular position of the contacting regions shown results when the contact arms spring open when the contact pin is inserted simply because the contact arms have the offset or the upper offset shown in FIG. 2. If necessary.
  • the contact areas of the contact arms are provided with a corresponding bend during the manufacturing process in order to achieve a small angle of approximately 4-5 ° here.
  • FIG. 4 shows a strip of strip material from which contact elements are punched out.
  • the outer shape of the flat contact element is first punched out, the individual contact elements being still connected to one another at an upper and lower connecting strip 13, 14.
  • the offset region 7 of the contact elements is then formed in a bending process.
  • a surface treatment of the contacting areas can optionally be provided, and after the upper and lower connecting strips have been cut off, the individual contact elements are available for further processing.
