  • the connection element can then be enclosed in a housing Interior, for example on a rear wall of the equipment, to be ordered. Because of the flat contact of the tab the relevant housing section is a risk of injury compared to terminals that have parts that stand away from the housing wall, significantly reduced.
  • the tab can be closed at its neck section, slotted or provided with fingers. It can go further be flat or curved. Essential is that it has cutting edges that go into the Cut the edge of the opening into which you will insert it is. A bend or curvature of the neck section with a radius lying in the plane of the contact surface increases the rigidity of the tab against bending and allows some elasticity in relation to the Opening.

After this Hooking the hook section into the opening and the Swiveling the housing towards the carrier pulls the Neck section smoothly into the opening even when he has a clear excess.
  • This is a safe one electrical contact with, for example, through a sheet formed carrier ensured. Lacquer or oxide layers are easily penetrated. There are no additional ones Fasteners such as screws, rivets or the like, as well as additional work steps for contacting of the wearer required.
  • the tab can be inexpensively used as a stamped and bent part produce, with the neck section and the Hook section in each case essentially straight trained sections of a sheet metal tab can be. These are preferably angled at least 90 ° to one another. This creates an angle between the neck portion and the hook section, which is at most 90 ° is great. This preferably acute angle causes the tab with its free end, i.e. with their hook section on the back of the carrier before the Housing rests with its contact surface on the carrier. This will ensure that the neck section is under Leverage is drawn into the opening and that the Hook section with the connection element installed its tip rests on the carrier.

So it will enables an additional and independent of the carrier Connect conductors that are connected to other elements is. This can be provided, for example, on the equipment Parts or assemblies that are assembled in isolation but must still be grounded. So that's it too possible a non-electrically conductive carrier for the To provide connection element and the desired contact with a conductor inserted in the slot.
  • the insulation displacement connection between the conductor and the tab is created when the tab is inserted into the Opening of the support part through the leverage of itself with the hook portion on the support part Tab. This is with the help of tools low operating forces possible and can therefore be carried out manually. It does not matter whether the line stripped or not stripped before insertion. Besides, can a continuous line can be connected to the leads to another connection on both sides. If necessary, several lines can also be connected.
  • a particularly firm and against subsequent loosening the tab is securely seated in the opening, if the neck portion has an abutment shoulder that essentially in the one defined by the contact surface Level lies.
