  • Such contact springs are generally known and for example described in DE-U 92 02 365. Such contact springs will u. a. to a large extent as a connector in automotive engineering used.
  • the contact spring consists of regularly a basic spring, two of which are integral at one end Extend spring arms of a contact part, with between the two spring arms a contact pin can be inserted. On the other end of the base spring closes a connector for an electrical supply line.
  • the connector can be used, for example, as a crimp connection a conductor wire claw and an insulation claw be connected to an electrical supply line or its casing be pinched.
  • the contact spring sits on the base spring Locking sleeve, which is also called a spring.
  • the locking sleeve essentially has the function of the spring force of the Increase contact spring and by training with or several locking tongues a releasable locking of the contact spring in an associated contact chamber of a surrounding housing To enable insulation material.
  • the locking sleeve is usually made of a material with good Spring properties, while the basic spring from one material with good electrical and thermal properties is made.
  • the locking sleeve can be used, for example, as a stamped and bent part be made of sheet metal.
  • the base spring is preferred also a stamped and bent part, but exists because of the necessary good electrical properties made of tin bronze or so-called spring bronze.
  • Sealing plates e.g. B. rubber sheets to use.
  • the contact springs must pass through these sealing plates on the outer casing are arranged, are passed.
  • the sealing plates used especially if the contact elements are damaged passed through this sealing plate several times in both directions must be, as is the case with a Repair of the connector may be the case.
  • the sealing plates indeed have openings through which the contact springs can be performed. These openings are for achievement a sufficient sealing effect in diameter smaller than the diameter of the contact springs, so that when the contact spring is pushed through these openings the openings of the sealing plate have to widen and expand.
  • the known contact springs are characterized by sharp-edged elements, especially when pulling back the contact spring from the contact chamber the sealing plate violate.
  • These sharp-edged elements are the one at the usual contact springs provided locking tongue on the locking sleeve and, if present, one at right angles from a side wall the locking sleeve of sharp-edged polarizing lobes.
  • the invention has the object of specifying a contact spring which is improved compared to the previously known contact springs and is ideal for use in enclosures that is provided with a sealing plate.
  • the invention is essentially based on a contact spring with a basic spring known per se, like this one for example in the earlier patent applications P 196 11 698.8 or P 195 13 582.2 is described, a novel To put on the locking sleeve that has no sharp-edged elements, in particular has no locking tongue.
  • the locking sleeve has rather a recess in which a corresponding Locking element of a surrounding housing in which the contact spring is inserted will intervene.
  • the recess in the locking sleeve is arranged according to the invention in an area which the Spring arms of the base spring protrude.
  • the above-mentioned recess over the extends over the entire width of the locking sleeve. This allows one correspondingly wide version of the locking element within of the surrounding housing, so that to solve the caused thereby Primary locking higher forces are to be applied. An unwanted one Pulling one out properly into a contact chamber a contact spring used is only possible with relatively high effort.
  • the locking sleeve is box-shaped trained and on one of their outer walls provided a polarizing flap.
  • the polarization flap is both in the direction of insertion and opposite to Seen plug-in direction formed without edges. This will ensures that when performing the contact spring through a sealing plate, e.g. B. a rubber sheet, not an unwanted one The rubber plate is excited.
  • the polarization flap can be realized in a simple manner that at the mentioned wall of the locking sleeve with a suitable stamp a rag is pushed out.
  • Another development of the invention provides that the Locking sleeve at its front end towards the mating side protective flap having.
  • These protective flaps are useful either bent obliquely inwards or bent back by 180.
  • these protective flaps can be stamped be provided. These measures ensure that when initially plugging the contact spring through the mentioned Sealing plate also no sharp-edged elements occur that could damage the sealing plate.
  • Figures 1 and 2 show in two different top views an embodiment of a contact spring according to the Invention.
  • Figure 2 is the contact spring shown in Figure 1 shown rotated 90 to the right along its longitudinal axis.
  • the contact spring is designated by the reference number 1 and has a known base spring 10.
  • Such a basic spring 10 is, for example, in the older ones Patent applications P 196 11 698.8 and P 195 13 582.2 detailed described, therefore expressly for the purpose of disclosure to these two older, but not yet pre-published Patent applications are referenced.
  • the base spring 10 has a connecting part 11 and a contact part 12 on.
  • the connector is in the embodiment Figures 1 and 2 designed as a so-called crimp connection with an insulation claw and a conductor wire claw which an electrical supply line can be connected.
  • a crimp connection can also be implemented in any other way the connecting part can be selected, for. B. a so-called IDC connector, an insulation displacement connector or the like.
  • the Contact part 12 of the base spring 10 is in one piece with the connecting part 11 in connection.
  • On the side facing the mating side End has the basic spring 10 in a known per se Way via at least two spring arms 13, which serve as an introduction funnel for one to be inserted between the two spring arms 13 Pin contact are provided.
  • a box-shaped locking sleeve 20 sits on the base spring 10 pinching open.
  • the locking sleeve 20 which overlap a tab 21 four side walls clamped together has, extends beyond the spring arms 13 in Towards the mating side of the contact spring 1.
  • the locking sleeve 20 at its end facing the plug side with two opposite Protective flaps 23 which are at an angle of are bent inward about 45 degrees.
  • These two protective flaps 23 can also be stamped be.
  • two further protective flaps 24, 25, each with their ends are bent back 180 degrees.
  • the protective flap 24 is sufficient with its bent end approximately to the distal ends the protective flap 23.
