Definitions

  • the invention relates to a circular plug-in sleeve from a stamped sheet metal part according to the preamble of claim 1, which is equipped with an over-spring also consisting of a stamped sheet metal part and is based on DE-A-27 31 001.
  • a circular plug-in sleeve which has a claw area and a plug-in area.
  • the plug-in area begins after the claw area with a cylindrically rolled spring arm base, which has longitudinally extending abutting edges, and to which three contact spring arms, which extend to the front and extend in extension of the cylinder wall, are connected. H. at a lateral distance from each other. With their front end, the contact spring arms are connected to a cylindrical plug-in ring, which also has longitudinally extending abutting edges. To form contact points for a suitable round plug, the contact spring arms are bent in an arc toward the interior of the round plug sleeve. Detent spring arms are also connected to the plug ring, specifically in the gaps between the spring arms, which extend backwards, are of the same length or shorter than the contact spring arms and are bent outwards.
  • the object of the invention is to increase the spring forces of the circular receptacle with spaced contact spring arms and also to provide protection against the spring arm base being bent open.
  • the over-spring known therefrom is not suitable for the generic round socket with spaced spring arms.
  • a socket body is provided which is rolled from spring plate, which is why it has a longitudinal joint.
  • the socket body has at one end a connecting terminal for an electrical conductor and at the other end a mouth for inserting a round plug pin.
  • a transverse slot is provided in the area behind the mouth opening, as a result of which an annular end section is formed. Starting from the cross slot.
  • the socket body likewise has longitudinal slots arranged symmetrically to the longitudinal joint.
  • two contact fingers running next to one another and extending in the longitudinal direction of the socket body are formed together with the longitudinal joint.
  • the free end of the two contact fingers delimited by the transverse slot, faces the mouth opening.
  • the contact fingers are bent radially inwards into the interior of the socket body.
  • Another round plug contact socket is known from NL-A-110477, but in which a socket body is provided without any contact spring tongue.
  • the socket body consists of a cylindrically rolled sheet metal stamped part, which has an opening in its circumferential surface through which a contact spring tongue of a sleeve plugged onto the socket body engages radially into the interior of the socket body in order to ensure contact with an inserted plug pin. Therefore, this known plug contact socket can give no suggestion for the arrangement of a spring on a circular socket of the type described above.
  • the circular plug-in sleeve 1 made of a stamped sheet metal part is equipped with a spring 2 made of a sheet steel part.
  • the circular plug-in sleeve 1 has the conductor area 3, which can correspond to the usual spatial shapes. Instead of the claw area 3, a solder connection part can also be provided.
  • the claw area 3 merges into a cylindrically rolled spring arm base part 4, the longitudinal edges of which are arranged opposite one another or abutting one another.
  • At the ring edge 6 of the base part 4 are two forward extending contact spring arms 7 connected at a lateral distance from one another, so that a gap 8 is formed.
  • the spring arms 7 are bent to form contact points, as is known per se, so that there is a narrowing of the cross section in the interior of the sleeve.
  • the contact spring arms 7 are connected to a plug-in ring 10, which preferably forms a closed ring which has only two abutting edges which extend in the longitudinal axial direction of the sleeve.
  • the middle part is cut out from the third contact spring arm, so that only a tab 39 attached to the spring arm base part 4 and a tab 40 attached to the plug ring 10 remain.
  • the flaps 39 and 40 are - as shown - bent inwards, ie towards the interior of the sleeve. The function of the inwardly curved tabs 39 and 40 is explained below.
  • an over-spring 2 with at least one connecting web 31, but preferably with two adjacent connecting webs 31 arranged on a gap 29, which are connected to the rear edge 27 of the over-spring ring 14, extend to the rear and sit on the clamp ring 32.
  • the captive fit of the over-spring is ensured by at least one tab 34 cut out of the cylinder wall of the clamp ring 32, which is flanged inwards and thereby engages through a hole 36 formed in the base part 4 of the circular plug-in sleeve 1 and engages around an edge of the hole 36.
  • two holes 36 and two tabs 34 can also be provided, the tabs 34 being flanged in opposite directions.
  • the over-spring 2 ends in the rear area with a plug-limiting bead 38.
  • Three locking spring arms 28 are preferably arranged between the connecting webs 31.
  • a third connecting web is separated from the spring washer 14 and bent inwards as a contact spring tongue 41. It passes through the gap 29 between the two tabs 39 and 40. In the front end region, the tongue 41 is bent outwards with an arc 42, which results in the convex contact line 43.
  • the inserted contact pin (not shown) is pressed by the spring force of the contact spring tongue 41 against the contact spring arms 7, which are preferably bent inwards, which ensures very good contacting.
  • the also inwardly bent tabs 39 and 40 prevent the contact spring tongues 41 from overbending because they support the inserted contact pin in the radial direction, so that the pin can only push the tongue 41 back to the imaginary connecting line between the ends of the tabs 39 and 40.
