A contact insert for a connecting terminal of a multiplicity of mutually isolated connection elements, designed in particular for printed circuit boards, with a spring force element being mounted symmetrically, with the spring force element designed with a simple section geometry and its simple mounting together with the advantageous connection to the contact insert, results in a closed terminal cage which makes it possible to reduce the physical height of the dielectric housing to a major The connecting terminal is used as a linking element in printed circuit board connection technology for providing a reliable supply to industrial electronics and economic individual wiring on printed circuits.
