Abstract
In a multipin connector to be fixedly mounted over a conductor access opening in a supporting wall of a digital device of the type operated by signals having frequency components capable of radiating electromagnetic waves about 5-30 Megahertz, which connector includes a header to be secured over the access opening, supports for fixedly supporting a plurality of conductor interconnecting pins on parallel axes passing through the access opening in a preselected pin layout pattern and the header providing for electrical isolation of the pins one-from-the other, there is an improvement. This improvement is a pin encircling member formed of a blend of finely divided particles surrounded by an electrically non-conductive material wherein the blend of particles include at least a first material having a high magnetic permeability and a low magnetic retentivity and a second electrically conductive material. This encircling member has a central bore or cavity with an inwardly facing profile generally matching the pin pattern so that the encircling member can be fixedly mounted onto the header itself. Electrical energy is concentrated and dissipated by the pin encircling member itself. The use of this improved connector reduces EMI at the connector and for the incoming or outgoing harness.
