Definitions

  • the invention relates to an electrical contact element according to the preamble of claim 1.
  • Such contact elements are needed to establish an electrical connection between an electrical conductor, in particular a stranded conductor, and a terminal end of a pin or socket contact.
  • connection technique of crimping is frequently selected.
  • the DE 88 040 92 U1 shows an electrical contact element that was produced in stamping and bending technology.
  • the electrical contact element is designed either as a pin contact or as a socket contact, the connection of a stranded conductor to the contact element being effected by crimping.
  • the crimping region of the contact element is designed substantially as a U-shaped open element. This open crimping range has the advantage that stranded conductors of different diameters can be connected to the same contact element.
  • US 5653 615 A1 proposes a contact element, which is essentially a hollow cylinder - that is not solid - formed.
  • the EP 0 197 821 A1 shows a contact element which is composed of three different segments.
  • the DE 19 92 567 U shows a contact element, designed as a pin or socket contact, which is made of solid material.
  • the GB 346 008 A shows a contact element, the contact area is executed wrench-like.
  • connection region has approximately centrally an outwardly curved lamellar structure.
  • the US 2004/0171314 A1 shows a female contact with an open crimp connection.
  • the EP 0 061 587 A2 shows a contact, which consists of solid material and which has wavy, axial slots in the contact area.
  • contact elements made of solid material which have a crimping area for connecting stranded conductors.
  • Such contact elements are made, for example, by a piece of wire defined length is separated and the contours of the contact element are machined out of this piece of wire, for example using the rotation technique.
  • these contact elements of the crimp is formed as a hollow cylinder with a closed lateral surface. This crimping area is intended only for connecting an electrical conductor cable Diameter suitable.
  • each different contact elements made of solid material must be used.
  • the object of the invention is to propose an electrical contact element, which has a low electrical resistance and which is suitable at the same time for the electrical contacting of stranded conductors of different diameters.
  • the electrical contact element is made of solid material.
  • the turning technique is used on curved or CNC-controlled machines.
  • the contact region of the contact element is designed as a socket contact.
  • the connection region is designed as a crimp connection in order to be able to contact in particular stranded conductors electrically.
  • the strands of an electrical conductor cable to be connected are inserted into the connecting region formed as a hollow cylinder.
  • the hollow cylinder is slotted in the axial direction and is thereby opened laterally.
  • a force is exerted on the lateral surface of the slotted hollow cylinder, so that the opposite slot edges are bent inward and rolled up.
  • the permanently deformed connection area of the contact element are now the compacted strands of the conductor cable.
  • the slotted hollow cylinder is suitable for crimping stranded conductors of different diameters. Without the axial slot cavities would form in the crimp or terminal area in stranded conductors with too small diameter, which allow oxidation processes and adversely affect the cable pull-out forces.
  • the contact element during the current flow is advantageously less heated than a contact element that was produced in stamping and bending technique.
  • the length of the axial slot in the connection area is more than half the length of the hollow cylinder.
  • the hollow cylinder is in the axial direction more than half of its length slashed. This prevents the formation of cracks in the lateral surface of the hollow cylinder during the crimping process. Through the cracks, air (but also other media) can reach the strands of the conductor cable. As a result, oxidation processes can be triggered which worsen the electrical properties of the electrical contact, for example the resistance.
  • the hollow cylinder of the connection area is, in addition to the axial slot, slotted at least once more.
  • This second slot is aligned substantially 90 ° to the first, axial slot. In other words, the second slot is formed across the axis of the first axial slot.
  • the base surface of the hollow cylindrical body will be circular in the connection region of the contact element.
  • other geometric shapes such as rectangle, square, ellipse or oval can also be advantageous and can be realized by means of turning or milling technology.
  • a ring element is formed between plug and connection area.
  • the ring element is disc-shaped and serves to fix the contact element in a matching shape in the insulating body of a connector.
  • the ring element can also be shaped differently geometrically, for example rectangular, oval or square.
  • the FIG. 1 shows an example of a pin contact.
  • the contact element 1 can be subdivided into a contact region 2 and a connection region 3.
  • the contact region 2 is formed as a pin contact 2a.
  • the connection region 3 is formed by a hollow cylinder 3 a, which contains an axial slot 4. Between contact and connection area there is a ring element 5.
  • An insulating body, not shown here, for the inclusion of contact pins is provided, contains a recess into which the ring element 5 of the contact pin can be inserted. As a result, the contact pin is held in the insulating body.
  • the FIG. 2 shows an example of a socket contact.
  • the contact region 2 is formed from a hollow cylinder, in which wedge-shaped slots 2c are introduced, so that individual spring arms 2b are formed. The end portions of the spring arms are bent inward to the mating opening, so that a circular mating opening is formed.
  • the ring element 5 here essentially has the diameter of the bush-shaped contact region 2.
  • FIG. 3 shows the socket contact according to the invention.
  • the same parts bear the same reference numerals.
  • the connection region 3 of this female contact has, in addition to the axial slot 4, a second slot 6, which is oriented essentially transversely to the axial slot 4.
  • the FIG. 4 shows another example of a pin contact.
  • the contact pin has a U-profile 7.
  • a wedge-shaped slot 6 ' is introduced in the U-profile 7.
  • the flanks 7a of the U-profile are chamfered. In other embodiments, the flanks 7a may also be parallel or inwardly or outwardly inclined.
  • FIG. 5 shows another example of a pin contact.
  • the same parts bear the same reference numerals.
  • the contact and connection region is here separated via a surface element 5 ', which is essentially rectangular.
  • FIG. 6 shows another example of the socket contact.
  • the contact element 1 has a cable jacket connection region 8.
  • This area is likewise formed by a hollow cylinder which has an almost continuous axial slot 10.
  • the diameter of the hollow cylinder of the cable sheath terminal portion 8 is larger than that Diameter of the hollow cylinder of the connection area 3.
  • the cable jacket connection region 8 is separated from the connection region by a slot 9, which runs perpendicular to the axial slots 4 and 10. In the cable jacket connection region 8 of the insulating sheathing of the conductor cable is fixed. This happens parallel to the crimping process.
  • the FIG. 7 shows a way to machine the contact elements, ie bring in the insulator of the connector.
  • the contact elements 1 are strung on a tape 11 in locking clips 12 and can be fed to a loading unit, not shown.
  • On the belt 11 can also be the contact elements according to the FIGS. 2 to 6 , or a mixture thereof, to be strung and processed.
  • FIG. 8 shows an example of another contact element 1, which is designed as a pin contact.
  • a notch 5a is incorporated in the ring member 5.
  • this notch 5a engages a not shown nose between the locking clips 12 of the belt 11, so that the individual pin contacts are aligned on the same band 12. This ensures a trouble-free mechanical processing of the contact elements.
