Definitions

  • the invention relates to a press-in contact with a Crimpulatel for a printed circuit board according to the features of the preamble of claim 1.
  • the invention is therefore based on the object to provide a rationally producible and universal contact with which a conductor track of a circuit board can be quickly, easily and electrically and mechanically reliably connected to the electrical conductor.
  • problems with particularly high ambient temperatures should be avoided.
  • the device for contacting an electrical conductor of a cable with a conductor track of a printed circuit board is designed as a press-in contact, which can be inserted into an opening of the printed circuit board and can be fixed without soldering and can be electrically contacted with the conductor press-in area and a contacting area for fixing and electrical contacting having the end of the electrical conductor of the cable.
  • the invention thus provides a press-fit, which can be produced in a simple manner in a stamping bending process.
  • the stamping and bending process has the advantage that in an automated process the press-in contact is shaped so that it can be further processed (assembled) in an automated manner and moreover produces the required electrical and mechanical contact reliability.
  • the press-fit on the one hand on a press-in with which it is inserted through a corresponding opening in the circuit board and thereby positively and / or positively fixed.
  • the corresponding shaping of the press-fit region ensures that, on the one hand, the electrical contact to the conductor track is produced reliably and permanently and, on the other hand, the press-in contact is fixed in position on the printed circuit board, so that the electrical conductor can be struck at its contacting region facing away from the press-in region.
  • the contacting region for the electrical conductor is designed so that the prepared end of the electrical conductor by soldering, welding, crimping, gluing with an electrically conductive material or the like can be attached there.
  • the configuration of the contacting region as crimping region is particularly preferred since a crimped connection produces a gas-tight and thus permanent connection and, on the other hand, different types of electrical conductors (round or flat conductors of different cross-sections) can be fixed to the press-fit contact.
  • the press-fit region and / or the contacting region are designed such that the press-fit contact can be fixed reliably, quickly and permanently by force and / or positive and / or material connection with the conductor track of the printed circuit board or the electrical conductor.
  • the pressing of the press-in contact in the opening of the circuit board, whereby the conductor track and press-in contact are electrically contacted with each other and the Press-in contact on the circuit board fixed in position and thus secured also has the advantage that such ambient temperatures can prevail, which would bring a solder joint to melt.
  • the connection between the press-fit contact and the electrical conductor is also high-temperature resistant, such as, for example, a crimp connection.
  • FIGS. 1 and 2 an embodiment to which the invention is not limited is shown in FIGS. 1 and 2 and described below.
  • a press-in contact 1 is shown in an angled variant (although other, in particular rectilinear variants are conceivable). This means that the contacting region projects perpendicularly from the surface of the printed circuit board or is aligned approximately horizontally with respect to the surface of the printed circuit board.
  • the press-in contact 1 is inserted through a corresponding opening in a circuit board 2 with its press-in area 3 and fixed there.
  • the press-in area 3 is provided in this embodiment with a slot 4, so that the legs are bent slightly outward next to the slot 4 and thus expand so far that the expansion is slightly larger than the diameter of the opening in the circuit board 2.
  • a contacting region 5 on the electrical conductor not shown here for example a round conductor, a stranded conductor, a flat conductor or the like
  • stripping ie after removal of the outer jacket
  • mechanically determined for example a soldering, welding, electrical bonding or the like
  • a crimping is possible, for which the contacting region 5 has a U-shape with two wings 6 in cross-section prior to insertion of the electrical conductor.
  • the crimping process is carried out by means of a suitable crimping tool, in which the two wings 6 are bent inwards, thereby contacting the electrical conductor in a gastight manner. It is particularly advantageous if the contacting region 5, in particular the crimping region, is matched to the geometry of the electrical conductor, in order thus to achieve the best possible connection results.
  • FIG. 1 shows that the press-fit contact 1 has an angular, preferably square, cross section, at least in the region between the slot 4 and the contacting region 5.
  • the slot 4 disappears after the press-fit contact 1 has been pressed into the opening of the printed circuit board 2 completely, that is, the press-in area 3 is completely compressed ( Figure 2, right view). However, it still has an outer diameter which is at least slightly larger than the inner diameter of the opening in the printed circuit board 2. It is also conceivable to bend the downwardly protruding end portion of the press-fit 1 below the press-in area 3 for the purpose of conditioning this end on or on the Conductor 8 and thus improved contact (also Figure 2, right representation).
  • the press-fit contact 1 shown in the figures has the particular advantage that it can be produced quickly and cost-effectively in a stamped bending process.
  • the invention is thus preferably (but not limited) to a pure crimp-Einpressstair.
  • This creates the opportunity to contact, for example, stranded cable on rigid or flexible printed circuit boards (so-called PCB's: Printed Circuit Boards) with the conductor tracks thereon.
  • PCB's Printed Circuit Boards
  • This is particularly advantageous when the assembly (for example, an electronic device with a printed circuit board in a housing) is exposed to temperatures that is above the range of use of solder joints.
  • the press-in area and the crimp area can be designed in different variants, in particular with regard to size, cable cross-section, press-fit zone, insulation crimp etc. It would also be possible to provide a soldering or welding area instead of the crimping area.
