Definitions

  • the invention relates to a socket contact for lockable insertion into a housing bore, with an essentially cylindrical base body and an adjoining tubular contact section which is open to the contact side and has at its free end an outwardly directed, annular locking shoulder and at least three , Is provided over the circumference substantially uniformly distributed, open to the free end of the contact section.
  • socket contacts are often part of plugs or sockets.
  • the socket contacts can be inserted into housing bores, whereby the annular shoulder can be pressed radially inwards due to the slots provided, in order to pass through a narrower housing bore. After passing through the narrower housing bore, the shoulder can move outwards again.
  • the slots have to be made relatively wide so that the annular shoulder can pass through the narrow housing bore.
  • the wide slots have the disadvantage that the cross section of the contact socket available for current transmission is reduced. This means that a larger socket contact must be used overall.
  • the slots can be kept narrower than before, which means that a larger cross-sectional area is available for power transmission.
  • the locking effect of the shoulder is not affected by the flattening, since the shoulder protrudes outwards as much as in earlier plugs.
  • the recesses created by the flattenings extend to the outer circumference of the tubular contact section. In other words, this means that the locking shoulder in the area of the slots is completely removed by a straight cut.
  • four are each other Opposed slots provided in pairs. This is also known as a cross-slot arrangement. With this cross-slotted arrangement, the optimum is achieved between the cross-sectional area available for the current passage on the one hand and the compact design on the other.
  • the insertion of the socket contacts into the housing bore can be simplified if the annular outer shoulder is chamfered towards its axial free end.
  • an annular stop shoulder is provided in the area of the base body of the socket contact. Then the socket contact can be mounted so that it is inserted with the contact section first into the housing bore, to the extent that it strikes the stop shoulder on a step of the housing bore.
  • the area of reduced cross-section of the housing bore is dimensioned from its length such that it corresponds to the distance between the stop shoulder and the locking shoulder. This means that the locking shoulder can move radially outwards again after inserting the socket contact into the housing bore, in order to also reach behind a step in the bore. The socket contact is then locked and can no longer be released on its own.
  • the invention also relates to a socket or such a plug equipped with the above-described socket contacts according to the invention.
  • socket contact 1 can be provided in housing bores 2 of a plug or a socket.
  • the exemplary embodiment shown here is a housing bore 2 with a first stop step 3 and a detent step 4 arranged at a distance behind it.
  • the internal cross section of the housing bore 2 is reduced in the area between steps 3 and 4.
  • an additional taper 5 can be provided which, in conjunction with a conical surface 6 on the base body 7 of the socket contact 1, ensures that the same is centered.
  • the socket contact 1 itself has a radially outwardly directed stop shoulder 8 on its base body 7
  • a tubular contact section 9 extends towards the contact side of the socket contact 1 and has a radially outwardly directed latching shoulder 10 at its free end.
  • the tubular contact section is slotted in its longitudinal direction, a total of four such slits 11 being provided.
  • the axial free end of the locking shoulder 10 is provided with a chamfer 12.
  • a tubular crimp connection 13 to which a cable 14 is connected is provided on the side of the base body 7 opposite the contact section.
  • the locking shoulder 10 is flattened in the area of the slots 11.
  • the recess 15 formed by the flat 15 extends almost to the outer circumference of the tubular contact section 9.
  • the flat 15 extends straight, in the form of a secant, through the circle described by the outer circumference of the locking shoulder 10.
  • the flats 15 ensure that in each quadrant only a third of the outer circumference of the locking shoulder 10 is not affected by the flattening.
  • the pin contact 16 is pushed into the contact section 9 of the socket contact 1, as a result of which the locking shoulder 10 behind the locking step 4 is blocked.
  • the socket contact can now no longer be removed from the housing bore 2 by external action.
  • a solder connection can also be provided, the housing bore not having to be designed differently for this purpose, since the soldering can also take place before the socket contact 1 is inserted. It must also be added that the socket contact 1 can also be inserted into a bore of a contact carrier instead of into a housing bore in a socket.
