The present invention relates to a contacting unit (t) for electrical conductors or pin contacts (). Contacting units () of this kind are used for reversibly contacting said conductors or pin contacts () in an electrical and mechanical manner. In the present invention, the spring force that acts on a conductor or pin contact () to be connected can be variably adjusted. To this end, the free, spring-loaded length of a spring contact member () is varied by means of a sliding element (). As a result of the variation of the spring-loaded length of the spring contact member (), the spring force is increased in the case of a shortening and is correspondingly reduced in the case of an extension.

In order to simplify the assembly of printed board connectors, there is provided an assembly aid that features one or more recesses in accordance with the dimensions of the printed board connectors, wherein one or more printed board connectors to be assembled on a printed board can be inserted into said recesses. The contact spacing on the printed board corresponds with the arrangement of the printed board connectors in the assembly aid such that an exact alignment of the printed board connectors is realized. The assembly aid remains on the printed board until the soldering process is completed, wherein this prevents, for example, flotation of SMD components.

Assembly aid for printed board connectors

In order to simplify the assembly of a shielded connector, it is proposed that an electrically insulating base body provided as a carrier for electric contacts features a mounting surface with two openings, wherein a recess that respectively features an integral collar on its inner side is respectively arranged around these openings. In addition, the base body is provided with lateral fastening elements that respectively feature a window formed by a frame. The frame can be positively fitted into the appropriate recess by bending the fastening elements such that the fastening element is positively and non-positively fixed on the base body. An electrically conductive shielding element that largely surrounds the base body contacts the fastening elements that, in turn, contact ground strips on the circuit board such that the connector is shielded from external voltages.
