Definitions

  • the invention relates to an electrical connection terminal a contacting area for contacting a complementary contact pin and with a connection area for connection to an electrical conductor, the Contact area from an inner contact spring, which merges into the connection area, and from an outer There is an external spring, the contacting spring at least two opposite contact spring arms has, which are supported by the outer spring.
  • an electrical connection terminal is included the features of the preamble of claim 1 known.
  • This electrical connection terminal has three each Pairs of contact spring arms, with the outer contact spring arms each with a side arm of the contact spring are connected and supported by this and the each middle contact spring arm has a free end and no support. This ensures that the contact spring arms have different contact forces. Pass the contact forces of the inner contact spring arm are not sufficient, so support is needed for this.
  • EP 114 187 discloses a double flat spring contact with a Overspring known, the overspring overspring arms has that parallel to the contact spring arms of the Double flat spring contacts run and from the outside on this Press the contact spring arms.
  • the spring clip arms run here essentially in the direction of insertion and point to Free ends towards the front.
  • DE-U-9202366 describes a connection terminal according to the Preamble of claim 1 with the tongue cut free.
  • the task is solved through an electrical connector with the characteristics of Claim 1.
  • the web is only on the long sides is cut free and thus supports a contact spring arm. But it is also possible to split the bridge into two tongues, the free ends of which are common or each one Press the contact spring arm.
  • An electrical connection terminal according to the invention can for example, be provided in a chamber Plastic housing to be introduced. It is common to the outer spring to provide locking spring tongues, the one Allow the terminal to be locked in the housing.
  • the Spring tongue on the same side of the outer spring Can be attached like the footbridge, as it takes up very little space claimed.
  • the electrical connection terminal can be in its connection area either two crimp areas or one or more Insulation displacement areas for contacting an electrical Have conductor.
  • the arrangement according to the invention is particularly advantageous for an electrical connection terminal with three pairs of Use contact spring arms, the middle of each a web of the outer spring is supported.
  • FIG 1 is a side view of an inventive electrical terminal 1 shown.
  • the electrical Terminal has a contact area 2 Contacting a complementary contact pin, for example a flat contact.
  • the electrical Terminal 1 a connection area 3, which in the present Embodiment of two crimp areas 4 and 5 consists.
  • Each crimp area 4, 5 has two opposite Crimp tabs on the inside when crimping be bent.
  • the one adjacent to the contacting area 2 Crimp area 4 is suitable for an electrical To be crimped on the ladder and the following one second crimp area is for crimping on the insulation of a suitable electrical conductor.
  • Insulation displacement connections for contacting an electrical Conductor Insulation displacement connections for contacting an electrical Conductor.
  • the contacting area 2 consists of an inner one Contact spring 6 and an outer outer spring 7. It is now the contact spring 6 based on the figures 5 to 8 described. As shown in Figures 5, 7 and 8 easily can be seen, the contact spring has three pairs opposite contact spring arms 8 to 13. The middle contact spring arms 9 and 12 have a free End on. In contrast, the respective outer contact spring arms 8, 10, 11 and 13 via a connection 14 to 17 am front end connected to side arms 18 to 21, which support the contact spring arms 8, 10, 11 and 13. How particularly easy to see from Figure 6, the run Contact spring arms 8 to 13 up to the contact point K on each other and then diverge. This will make one Insertion opening for the complementary contact pin educated.
  • the inner Contact spring 6 on a spring arm base 22 which in is essentially box-shaped.
  • This box. tapers in the middle of the long sides, thus in the area of the middle contact spring arms 9 and 12. This can be seen particularly easily from FIGS. 7 and 8.
  • the outer spring is essentially box-shaped. It has a top wall 23 and one Bottom wall 24, and two side walls 25 and 26. in the the central area of the side walls decreases Cross section of the outer spring. The cross section looks like a zero compressed in the middle. In this The area is a detent spring tongue 27, 28 on each side arranged.
  • This latch spring tongue is used to lock the Outer spring in a housing. It is the Latch spring tongue 27, 28 around a side wall 25, 26th cut out tongue. As can be seen, this is Detent spring tongue turned off from the housing, but protrudes beyond the maximum width of the outer spring not beyond. This will achieved that the surface of the outer spring as possible is smooth. When making contact with it The outer spring through a collective seal is the Collective seal not through the latch spring tongue damaged.
  • FIG. 15 shows a section through a housing chamber 30 an introduced contact.
  • the shoulders 31, 32 do not extend over the entire width of the chamber 30, but only in the middle area where the contact or the outer spring 7 has the taper.
  • each a web 29, 30 on its Longitudinal axis runs perpendicular to the direction of insertion and on two long sides is cut free.
  • the webs 29 and 30 are each bent inwards, whereby they protrude further into the outer spring than the tapered one Area. This is particularly evident from Figure 10. Further has the outer spring 7 bent at the end Stop tabs 31 to 36, the following functions fulfill:
  • these tabs ensure that when you insert one complementary contact pin this not next to but only can be inserted between the contact spring arms.
