Definitions

  • the invention relates to a socket contact with a base spring, which has a connecting part for an electrical conductor and a contact part with a spring leg base and spring legs extending therefrom for contacting a plug contact, and with a made of a stamped and bent part made of sheet metal, the contact part of the base spring box-shaped over-spring, which has a bottom wall, two side walls and a ceiling wall divided by a manufacturing-related longitudinal slot and on two opposite walls with cut out, bent inwards and resting on the spring legs of the base spring and a cut out of a wall, in the longitudinal direction of the Overspring extending, outwardly bent latching hook and is also formed with a polarizing element.
  • Such a socket contact is e.g. B. known from DE 9202366 U1.
  • contact springs are used which are designed as socket contacts and consist of a base spring and an over-spring which serves, among other things, to support the contact force for the base spring and surround the base spring in a box shape.
  • the spring also usually has additional functions and should z. B. - as in the known socket contact - cause a primary fuse and polarization of an insertable into a contact chamber of a contact carrier socket contact.
  • the over-spring is formed on one side with a cut-out, outwardly bent detent spring arm for primary securing, and on the same or on another side with a likewise outwardly curved tab-shaped web for polarization.
  • the spring is more suitable Way to attach to the base spring.
  • both the base spring and the spring are made from a stamped and bent part made of sheet metal. Due to a longitudinal slit that arises on one side due to the production process, the stability of the box shape of the over-spring can be impaired, particularly in the case of spring springs with additional functions.
  • the invention is therefore primarily based on the object of achieving the most stable possible box shape of the spring with a socket contact of the type mentioned.
  • a socket contact of the type mentioned according to the invention in that on the divided top wall of the spring a top wall part or both top wall parts in a lower part of the longitudinal slot facing the connecting part of the base spring and in an upper part area facing the contact opening side of the base spring Longitudinal slot is or are formed with a connecting tab directed towards the other ceiling wall part and that the connecting tabs extend beyond the longitudinal slot and are positively and / or non-positively connected to the respectively opposite ceiling wall part.
  • the socket contact 1 consists of a base spring 2 and a spring 3 and is in a contact chamber 4 of a contact carrier 5 ( Figure 4), z. B. in a single or multi-row contact chambers having socket housing an electrical connector.
  • the base spring 2 is with a z. B. formed as a crimp connection part 6 for an electrical conductor and with a contact part 7, which has a cross-section such.
  • the spring legs 9 and 10 of the base spring go z. B.
  • each spring leg has four contact lamellae, which results from the design of the over-spring described later.
  • the spring 3 is also rectangular in cross section, so that it encloses the entire contact part 7 of the base spring 2 with a bottom wall 13, two side walls 14, 15 and a top wall 16 in a box shape.
  • a latching hook 17 extending in the longitudinal direction of the spring is cut out and bent outwards as a primary securing element for a socket contact to be inserted into a contact chamber 4 of the contact carrier 5.
  • the over spring 3 is fastened in a simple manner to the base spring 2 in that it has folding flaps 18, 19 on its short side walls 14, 15 with small, formed by separating cuts and bent inwards and engaging in recesses 11, 12 on the side walls of the spring leg base 8 is provided.
  • the base spring 2 and the spring 3 are made of stamped and bent parts made of sheet metal and, as a result of the production process, have a longitudinal slot.
  • the longitudinal slots 21 and 22 of the base spring 2 and the over-spring 3 are each in the top wall of the two springs, ie the over-spring 3 has a top wall 16 divided by the longitudinal slot 22, which is divided here in the middle and thus two equally large top wall parts 16a and 16b.
  • the two ceiling wall parts 16a, 16b are connected in the exemplary manner described below.
  • the ceiling wall part 16a is formed in a lower portion of the longitudinal slot 22 facing the connection part 6 of the base spring 2 with an approximately rectangular connecting tab 23, which is bent upwards by a crank 24 from the ceiling wall part 16a, towards the opposite other ceiling wall part 16b extends beyond the longitudinal slot 22 and overlaps the other ceiling wall part 16b in a partial area.
  • the connection of the connecting tab 23 with the ceiling wall part 16b is carried out by plastic deformation (clinching), ie by plastic cold deformation and pressing the connection area into one another with an embossing stamp or, as shown, by welding, for example by welding. B. at two welding points 25. Instead of this non-positive, described type of connection z. B.
  • the top wall parts 16a and 16b are also connected to one another in an upper partial region of the elongated slot 22 facing the contact opening side of the base spring 2.
  • the other ceiling wall part 16b is formed with a connecting tab 26 in the illustrated embodiment.
  • This connecting tab 26 forms an end web 26a, which is bent outward at an angle of 90 ° to the ceiling wall part 16b and extends with a section 26b beyond the longitudinal slot 22.
  • a partial flap 26c is in turn angled from this section 26b by 90 ° and bent toward the opposite ceiling wall part 16a.
  • this partial tab 26c is in turn connected to the top wall part 16a by welding at a welding point 25.
  • the upright web 26a of the connecting tab 26, which is arranged centrally with respect to the longitudinal slot 22, forms a polarizing element for the socket contact, which is directed transversely to the direction of insertion of the socket contact, so that the socket contact is incorrectly inserted into the contact chamber 4 of the contact carrier 5.
  • the contact chamber 4 of the contact carrier 5 is designed with a corresponding polarization groove 22 for the web 26a of the socket contact.
  • the width of the connecting tab 23 provided in the lower part area is not greater than the width b of the web 26a in the same direction transverse to the plugging direction.
  • the height of the connecting tab 23 above the ceiling wall 16 is significantly less than the height h of the web 26a. So that's the dimensioning the connecting tab 23 within the contour of the polarization groove 20th
  • the spring 3 is formed on the top wall 16 and on the bottom wall 13 for each spring leg 9, 10 of the base spring 2 with an inwardly bent spring tongue.
  • the over-spring is provided here on both the bottom wall 13 and on the top wall 16 with four inwardly bent resilient over-spring tongues 27, which are approximately at the level of the contact zone 28 rest on the contact blades ( Figure 5).
