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.

Multipin connector and method of reducing EMI by use thereof

An improved electrical connector and connector system is disclosed which allows for the simultaneous mass connection of multiple isolated electrical circuits through means of a single connector assembly. A standardized connector housing has multiple terminal cavities therein, each cavity being capable of containing one or more isolated electrical terminals of various disclosed configurations. The terminals disclosed are generally flat and have a slit therein from the top end to accept and hold an insulated wire in a range of gauges and make electrical connection to the conductive core of the wire upon force fitting of the wire into the slit. In one configuration the top portion of the terminals and the slit therein are centered on the terminal so that two terminals can be inserted into a single cavity and a single connecting wire can be easily aligned with, held by and electrically connected to both of the individual terminals. In a second configuration, the top portion and the slit is offset from the center of the terminal so that a different wire can easily be connected to each of the terminals in a single cavity.
