A plug connector for printed circuit boards includes a number of contact elements positioned in a housing. The contact elements each have two connection ends and an intermediate contact positioned between the two ends, where one connection end is in the form of an insulation displacement contact for connecting wires. The insulation displacement contacts are supported on the housing, so that the contact elements are held captively in the housing when connection forces act on the insulation displacement contacts.

The invention relates to a plug-in connector for printed circuits, comprising a plurality of contact elements, whereby said contact elements have two connecting faces each. The one connecting face is configured as an insulation displacement contact for connecting cores and the other connecting face is configured as a tuning fork contact for contacting contact surfaces on a printed circuit. The insulation displacement contacts of the contact elements can be inserted into a plastic housing. At least one lower edge of the insulation displacement contacts is supported on the plastic housing so that the contact elements are captivated in the plastic housing when connecting forces act upon the insulation displacement contacts. The plastic housing comprises at least one chamber-type area. The tuning fork contacts are completely received by the plastic housing in the longitudinal direction. The contact element is configured as a two-part element, a first part of the contact element comprising the insulation displacement contact and the second part comprising the tuning fork contact. One contact arm each is positioned on both parts of the contact element and the two contact arms interact to give a disconnector.

摘要:
A measuring wheel detects forces and moments between the rim and axle of a vehicle wheel with measuring sensors between the rim face and a wheel flange apparatus transmits the energy and data to a measurement evaluation and processing system on the vehicle. The wheel flange and/or the front of the rim consists of a fiber compound, while the apparatus on the wheel for transmitting energy and data are fitted on the inside of the rim bed holding the vehicle tire and extends essentially over its circumference. Thus the static properties and dynamic behavior of the measuring wheel during travel correspond to the greatest degree to the original wheel. Effects which falsify the measurements such as increased wheel weight and the like do not arise.
