Communications connectors with self-compensating insulation displacement contacts
View Patent ↗Communications connectors are disclosed that include a housing having an upper end and a lower end, the upper end of the housing including a plurality of slits that define a plurality of pillars. First and second pairs of tip and ring insulation displacement contacts (IDCs) are mounted in the housing. Each of the IDCs has an upper end that has a first slot, a lower end that has a second slot and an intermediate portion between the upper end and the lower end, the lower end being offset from the upper end. The first slot of each IDC is aligned with a respective one of the slits. The housing further includes through slots that are separated by dividers, where each of the through slots is sized to receive the upper end of a respective one of the IDCs, and each slit of the plurality of slits exposes inner edges of the first slot of a respective one of the IDCs.
1. A communications connector, comprising:
a housing having an upper end and a lower end, the upper end of the housing including a plurality of slits that define a plurality of pillars;
a first pair of tip and ring insulation displacement contacts (IDCs) mounted in the housing;
a second pair of tip and ring IDCs mounted in the housing;
a third pair of tip and ring IDCs mounted in the housing;
a fourth pair of tip and ring IDCs mounted in the housing;
wherein each of the IDCs is substantially planar;
wherein each of the IDCs has an upper end that has a first slot, a lower end that has a second slot and an intermediate portion between the upper end and the lower end, the lower end being offset from the upper end;
wherein the first slot of each IDC is aligned with a respective one of the slits; and
wherein the housing further includes through slots that are separated by dividers, where each of the through slots is sized to receive the upper end of a respective one of the IDCs, and wherein each slit of the plurality of slits exposes opposed edges of the first slot of a respective one of the IDCs.
2. The communications connector of claim 1 , wherein the communication connector is mounted on a terminal block such that the first slot and the second slot of each IDC are on a first side of the terminal block.
3. The communications connector of claim 1 , wherein the tip IDCs are aligned in a first row within the housing and the ring IDCs are aligned in a second row within the housing.
4. The communications connector of claim 3 , wherein the intermediate portion of each IDC is received by the lower end of the housing.
5. The communications connector of claim 4 , wherein at least portions of the lower end of each of the IDCs extend outside the housing through one or more openings in the lower end of the housing.
6. The communications connector of claim 5 , wherein the IDCs of each pair of IDCs cross over each other.
7. The communications connector of claim 1 , wherein the upper end of a first IDC of the first pair of IDCs is substantially equidistant from the upper ends of both IDCs of the second pair of IDCs and is substantially equidistant from the upper ends of both IDCs of the third pair of IDCs.
8. The communications connector of claim 3 , wherein the first slot and the second slot of each IDC are generally parallel and non-collinear.
9. A communications connector, comprising:
a dielectric housing that includes a first row of through slots and a second row of through slots, and a plurality of dividers that separate respective ones of the through slots in the first row from corresponding through slots in the second row;
at least four pairs of substantially planar tip and ring insulation displacement contact (IDCs) mounted in the housing, wherein each IDC is at least partly received within a respective one of the through slots, with the tip IDCs received within the through slots in the first row of through slots and the ring IDCs received within the through slots in the second row of through slots;
wherein each of the IDCs has an upper end that has a first wire receiving slot and a lower end that has a second wire receiving slot, the first wire receiving slot and the second wire receiving slot of each IDC being generally parallel and non-collinear;
wherein an upper end of the housing including a plurality of slits that define a plurality of pillars; and
wherein each slit of the plurality of slits exposes inner edges of the first wire receiving slot of a respective one of the IDCs.
10. The connector block of claim 9 , wherein the upper end of a first IDC of the first pair of IDCs is substantially equidistant from the upper ends of both IDCs of the second pair of IDCs.
11. The connector block of claim 10 , wherein the first IDC of each of the pairs of IDCs crosses over the second IDC of its respective pair of IDCs.
12. The-connector block of claim 11 , wherein the upper and lower ends of the IDCs of the first pair of IDCs and the upper and lower ends of the IDCs of the second pair of IDCs are located to self-compensate for crosstalk between the IDCs of the first and second pairs of IDCs.
