Definitions

  • the invention relates to an electrical contact element, which is made of solid material, and which is designed as a pin contact or as a socket contact, and which has a plug-in area and a connection area, wherein the connection area is designed as a crimp connection for contacting an electrical conductor.
  • 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 contact elements carry at their conductor terminal end an axial bore, in which the stripped end of the stranded conductor is inserted and squeezed by crimping.
  • 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 area of the contact element is substantially U-shaped open Element formed. This open crimping range has the advantage that stranded conductors of different diameters can be connected to the same contact element.
  • contact elements made of solid material which have a crimping area for connecting stranded conductors.
  • Such contact elements are for example made by a piece of wire of defined length is separated and the contours of the contact element of this piece of wire, for. be worked out using the turning technique.
  • these contact elements of the crimp is formed as a hollow cylinder with a closed lateral surface. This crimping area is only suitable for connecting an electrical conductor cable of specific diameter. Thus, when connecting stranded conductors with slightly different diameters, 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.
  • connection area is formed as a hollow cylinder containing a slot in the axial direction.
  • the electrical contact element is made of solid material.
  • turning technology is used on cam- or CNC-controlled machines.
  • cutting operations are necessary.
  • the contact region of the contact element can be designed both as a pin contact or 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, allow the oxidation processes and negatively affect the cable pull-out forces.
  • conductor cables of different diameters can be electrically contacted.
  • 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 region 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 contact element of the hollow cylinder of the connection area in addition to the axial slot, at least one more times slit.
  • 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 diameter of the disk-shaped ring element is greater than the diameter of the pin contact.
  • the diameter of the disk-shaped ring element is equal to the diameter of the socket contact.
  • the ring element can also be shaped differently geometrically, for example rectangular, oval or square.
  • 1 is a perspective view of a pin contact
  • FIG. 2 is a perspective view of a socket contact

  • FIG. 1 shows a perspective view 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.
  • FIG. 2 shows a perspective view 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 a further variant of the socket contact.
  • 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.
  • FIG. 4 shows a further variant 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 a further variant of the 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 a further variant 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 jacket connection region 8 is greater than the diameter of the hollow cylinder of the connection region 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.
  • Figure 7 shows one way to machine the contact elements, i. to introduce into the insulator of the connector.
  • the contact elements 1 are strung on a band 1 1 in locking clips 12 and can be fed to a loading unit, not shown.
