Abstract

A terminal block for high transmission rates in the telecommunication and data technique. The terminal block includes a plastic casing and metal insulation displacement contact elements inserted pair-wise in at least two parallel rows into the casing with connected contact fingers forming spring contacts. The flat insulation displacement contact elements are formed at the narrow side webs including the contact slot therebetween and of the base web. The width of the spring contacts is small.

Dependent claims

A terminal block for high telecommunications and data transmission rates, the terminal block comprising:

a plastic casing;
a plurality of metal insulation displacement contact elements, each of said plurality of metal insulation displacement contact elements being formed of flat material and including narrow side webs, said side webs defining a contact slot between said side webs, a base web connecting said side webs, and a spring contact connected to said base web, said spring contact having a small width, said insulation displacement contact elements being positioned in said plastic casing to define a first row of contact slots and a second a second row of contact slots, said first row being opposite said second row, said insulation displacement contact elements being disposed in said plastic casing grouped in pairs, each pair including a first contact element and a second contact element, a spring contact of said first contact element of a pair of contact elements of said first row being disposed to engage a corresponding spring contact of a first contact element of a pair of contact elements of said second row and a spring contact of said second contact element of a pair of contact elements of said first row being disposed to engage a corresponding spring contact of a second contact element of a pair of contact elements of said second row, whereby a wire connected to said first contact of a pair of contacts of said first row is electrically connected to a wire connected to said first contact of a pair of contacts of said second row and a wire connected to said second contact of a pair of contacts of said first row is electrically connected to a wire connected to said second contact of a pair of contacts of said second row, said first contact of each pair being spaced from a second contact of said pair by a distance, said distance being smaller than a spacing between adjacent pairs in said first row and said second row.

A terminal block for high telecommunications and data transmission rates, the terminal block comprising:

a plastic casing;
a plurality of metal insulation displacement contact elements, each of said plurality of metal insulation displacement contact elements being formed of fiat material and including narrow side webs, said side webs defining a contact slot between said side webs, a base web connecting said side webs, and a spring contact connected to said base web, said spring contact having a small width, said insulation displacement contact elements being positioned in said plastic casing to define a first row of contact slots and a second row of contact slots, said first row being opposite said second row, said insulation displacement contact elements being disposed in said plastic casing grouped in pairs, each pair including a first contact element and a second contact element, a spring contact of said first contact element of a pair of contact elements of said first row being disposed to engage a corresponding spring contact of a first contact element of a pair of contact elements of said second row and a spring contact of said second contact element of a pair of contact elements of said first row being disposed to engage a corresponding spring contact of a second contact element of a pair of contact elements of said second row, whereby a wire connected to said first contact of a pair of contacts of said first row is electrically connected to a wire connected to said first contact of a pair of contacts of said second row and a wire connected to said second contact of a pair of contacts of said first row is electrically connected to a wire connected to said second contact of a pair of contacts of said second row, each said spring contact extending from an associated said base web in a direction away from an associated said contact slot.
