Abstract

A jack has a housing and connectors. A dielectric housing part forms with the housing an upwardly open seat shaped to receive and fit with a substantially complementary plug. A second flexible circuit board has a U-shaped outer end formed with a plurality of conductive jack fingers projecting into the seat. The jack fingers are connected via the first circuit board to the connectors. A U-shaped dielectric support fits complementarily within the U-shaped end of the second circuit board, has fingers like the jack fingers and fixed thereto, and is pivotal in the housing part between an inner position and an outer position. A U-shaped leaf spring fits within the support, has fingers like the support fingers, bears outwardly on the support, and is braced against the housing part to bias the jack fingers into the outer position.

Claims

1. A telecommunication or data-transmission jack comprising:

a housing;

a first circuit board carrying traces and forming a lower face of the housing;

connectors connected to the traces of the first circuit board and projecting from the first circuit board downward at the lower face;

a dielectric housing part forming with on the housing an upwardly open seat shaped to receive and fit with a substantially complementary telecommunication or data-transmission plug;

a second flexible circuit board having a U-shaped outer end and an inner end, the outer end being formed with a plurality of conductive jack fingers projecting into the seat and positioned in the seat to engage respective contacts of the plug when the plug is fitted in the seat, the jack fingers being connected at the inner end of the second circuit board to the traces of the first circuit board;

a U-shaped dielectric support fitting complementarily within the U-shaped end of the second circuit board, having fingers extending along the jack fingers and fixed thereto, the fingers of the jack and of the support being pivotal in the part between an inner position with the jack fingers spaced from an open end of the seat and an outer position between the inner position and the open end of the seat; and

a U-shaped leaf spring fitting within the support, having fingers extending along the support fingers and bearing outwardly thereon, and braced against the part to bias the jack fingers into the outer position.

2. The jack defined in claim 1, wherein there are eight of the jack fingers in a row.

3. The jack defined in claim 1, wherein the support is formed with aligned bearing pins seated in the part and defining a pivot axis for the support, the support and being formed with angularly directed stop faces permitting only limited pivoting of the support in the part for movement of the jack fingers between the inner and outer positions.

4. The jack defined in claim 1, wherein there are eight of the jack fingers, the jack further comprising:

latch formations in the part and projecting into the seat at a level between the outer position of the jack fingers and the open end of the seat and in an orientation to engage in grooves of end contacts of the plug.

5. The jack defined in claim 1, wherein the second board includes signal-processing means connected to the respective jack fingers.

6. The jack defined in claim 1, wherein the housing is of metal.
