Definitions

  • the invention relates to a plug-in contact element according to the preamble of claim 1.
  • plug-in contact elements are known, for example, from cable connectors for the sensors, as are used, for example, for connection to proximity switches.
  • a cable connector designed as an angle connector for example the "ELWIKA” type from the applicant
  • the sockets 2 fixed therein in a contact carrier 1 made of insulating material have radial bores 3;
  • the stripped end parts of the cores (strands) 4 of the associated cable cores 5 are passed through the radial bores 3 for contacting and soldered to the respective socket 2.
  • Tapered end sections 6 of the sockets 2 pass through holes in a circuit board 7 and are conductively connected to contact points by soldering 8 on the mating surfaces.
  • the invention is therefore based on the object of developing a plug-in contact element of the type mentioned in such a way that, in the simplest and cheapest possible manner, minimal effort is required for its electrical connection and any arrangement of the plug-in contact elements in a very confined space.
  • the end piece of each insulated cable core is first inserted into the blind hole of the associated plug contact element and bent through 90 ° into the guide section of the slot.
  • the end of the wire lies about the length of the insulation displacement section of the slot above the bottom of the blind hole.
  • the end pieces of the cable cores can of course be angled by 90 ° before being inserted.
  • the cable cores are then pressed either individually or all at the same time into the insulation displacement section of the slots, the insulation jacket in each case being cut through and the cable core core resting against the edges of the insulation displacement section under deformation, with its cross section deformed.
  • plug-in contact elements according to the invention are particularly suitable for contacting arbitrarily arranged contacts in a confined space with single wires, because, compared to the prior art, the end parts of the wires do not protrude beyond the connection point.
  • the plug-in contact elements according to the invention are particularly suitable for contacting arbitrarily arranged contacts in a confined space with single wires, because, compared to the prior art, the end parts of the wires do not protrude beyond the connection point.
  • the narrow ring collar formed by an embodiment of the blind bore according to claim 3 ensures at no extra cost that even non-pre-angled cable core end pieces are only inserted into the associated blind bore to such an extent that they have sufficient space in the blind bore when the cable cores are subsequently pressed into the insulation displacement sections without being excessively compressed or squeezed and without jeopardizing the safety of the insulation displacement connection.
  • a considerable simplification of assembly is achieved without any aids. Theoretically, this effect could also be achieved by a conical blind bore tapering towards the plug end.
  • the desired insertion depth would not be reliably achievable.
  • connection-side region of the blind bore up to the narrow annular collar Claim 4 is tapered, because in this way a light and therefore quick insertion of each cable core into the blind bore up to the collar is achieved in a very simple manner.
  • Known cable connectors for the use mentioned in accordance with the embodiment shown in FIG. 2 contain, as already described at the beginning, a circuit board 7 with electrical (for example resistors) and electro-optical (for example LEDs) components which on the through the tapered end sections 6 of the sockets 2 formed covenant rests.
  • electrical for example resistors
  • electro-optical for example LEDs
  • the connected cable is arranged at 90 ° to its axial direction, thus forming an angled plug connector.
  • An embodiment of the plug contact elements according to claim 6 makes it possible in a simple manner to produce cable plug connectors with a cable entry extending at any angle to the plugging direction (for example at an angle of 90 ° also "straight" cable plug connectors).
  • FIG. 1 shows an exemplary embodiment of plug contact elements according to the invention in a multipole angle connector for proximity switches in a partially sectioned view.
  • the angled connector 10 has a contact carrier 11 with cylindrical sockets 12 pressed therein and a printed circuit board 13 which is connected to electrical, e.g. Resistors 14, and optoelectric devices, e.g. LEDs 15, is connected to display switching states.
  • the sockets 12 are provided for the galvanic connection to the cores of the insulated cable cores 17 of a multi-core cable 18 designed as strands 16 for connection to the plug pins of a proximity switch (not shown) and to the associated contacts of the printed circuit board 13.
  • the sockets 12 are pressed into plated-through recesses 19 in the printed circuit board 13 - a particularly inexpensive solution in comparison to connection by soldering or connecting lines.
  • a union nut 20 with a knurled grip 21 is provided which engages behind a collar 22 of an annular collar 23 of the contact carrier 11.
  • the sockets 12 each consist of a plug-side socket part 24 and a connection-side end part 25, in which an axial blind bore 26 and a slot 27 are made in the bore wall 28.
  • the slot 27, the length of which is shorter than that of the blind bore 26, has a connection-side guide section 29 with a cutting zone 30 and an insulation displacement section 31 adjoining it.
  • the width of the guide section 29 is slightly smaller than the outer diameter of the cable wires 17, the width of the insulation displacement section 31 is smaller than the diameter of the strands 16.
  • the blind bore 26 has a plug-side area 32 and a connection-side area 33, the latter being slightly larger in diameter as the plug-in area 32 and, in order to facilitate the cable entry in the area of the slot 27, widens conically towards the free end of the socket 12.
  • the different diameters of the areas 32 and 33 form a narrow ring collar (34).
  • connection of the insulated cable cores 17 and at the same time their strain relief is particularly simple and inexpensive to produce in the following manner due to the described construction of the socket 12 according to the invention:
  • Each cable core 17 is first inserted into the blind bore 26 up to the annular collar 34, which is a little larger than the core diameter due to the conical insertion funnel, the smallest diameter (which corresponds to the diameter of the subsequent cylindrical part of the connection-side region of the blind hole 26) can be done easily and quickly.
  • the cable core is then bent through approximately 90 ° into the guide section 29 of the slot 27 and slightly clamped (pre-fixed) therein by the dimensions described.
  • the circuit board 13 with its plated-through recesses 19 is pushed onto the connection-side end parts 25 of the sockets 12.
  • connection-side end part 25 with a cross-section C-shaped in cross section in the area of the slot 27 results in a permanently secure contact by so-called "C-pressing" and a firm mounting of the printed circuit board 13.
  • plug-in surface 35 of the printed circuit board 13 at the same time all the cable wires 17 are pushed further into the slot, the insulation jacket of the cable wires 17 first being cut in the cutting zone 30 and then the strands 16 being pressed into the insulation displacement section 31 in such a way that they rest under pressure over a large area on their side edges and thus are permanently secure Ensure contact.
  • the free end of each cable wire 17 is almost completely inserted into the blind bore 26 in this process. An extremely simple assembly is thus possible without any auxiliary device or special operations.
  • the angled wire ends, together with the cable wires 17 held in the slots 27, furthermore result in a high strain relief, which cannot be achieved with conventional insulation displacement terminals.
  • this high tensile strength also makes it possible to carry out a direct encapsulation with plastic 36 in spite of the high forces occurring in the process.
  • the plastic 36 is also guided through a channel in the contact carrier 11 in the same working step and thereby forms a seal 37. This advantageously avoids the provision and assembly of a separate sealing ring.
  • the protruding wire ends which are not available in comparison to conventional insulation displacement terminals, also make it possible to arrange the sockets 12 in a confined space, an advantage which is particularly important in the case of connectors, which should always be as small as possible.
  • the plug contact elements according to the invention without any special measures, in contrast to the prior art, it is ensured that no stray wire strands and thus no short circuits or changes in the prescribed air and creepage distances between live parts can occur.
  • the plug-in receptacles designed according to the invention create a cable connector which is not only extremely cost-effective in terms of construction and manufacture, but also - as described - has a number of advantages which are particularly important for bulk articles such as connectors.
