The controlled impedance, low cross-talk, high density, EMI shielded electrical connector assembly comprises a receptacle connector and a plug connector for interconnecting circuits on mother and daughter printed circuit boards arranged orthogonally or in other configurations. Each of the receptacle and plug connectors comprises in preferable form, four rows of electrical contacts arranged in two outer and two inner rows. One set of inner rows and outer rows is each supported in an insulator of dielectric material which surrounds each contact and extends between an outer and inner row in each set. The contacts in the outer rows of each set are staggered with respect to the contacts in the inner rows. A conductive housing extends along the outer rows of contacts and further comprises a portion disposed adjacent the inner rows of contacts, the housing serving as a ground plane when connected to the boards. The ground plane is spaced from the contacts at a selected distance that when combined with the dielectric material of the insulators provides a selected characteristics impedance. Further, the conductive housing has a plurality of projections extending inwardly toward the outer rows of contacts and outwardly toward the inner rows of contacts, the projections extending partially between each of the adjacent contacts in the respective rows to provide a conductive barrier for cross-talk protection.

Controlled impedance electrical connector

An improved electrical filter connector comprises a capacitor sub-assembly including an insulative substrate, a plurality of capacitors soldered thereto and a ground spring. The ground spring is soldered to the ground terminations of the capacitors, the ground spring having a resilient portion for electrical engagement with conductive ground traces on a system circuit board. First terminations of the capacitors are electrically individually connected to respective contacts of the electrical connector. Second capacitor terminations are electrically connected to the ground strip. The capacitors are preferably of the discrete, monolithic chip type, having a dielectric body spaced between the electrical terminations thereof. A quantity of curable dielectric material is disposed on the dielectric bodies between each of the capacitor terminations to provide an enhanced dielectric medium to increase the capability of the connectors to withstand higher voltages during power surges.

Electrical filter connector

An improved method of making an electrical filter connector includes the steps of providing a substrate with a plurality of metallized openings therethrough for electrical individual attachment to electrical contacts of the connector. The substrate is further provided with a metallized strip on a surface thereof spaced from the metallized openings. A plurality of capacitors are attached to the substrate. First conductive capacitor terminations are individually electrically attached to respective portions of the metallized openings and second conductive capacitor terminations are electrically attached in common to the metallized strip. A curable dielectric material is applied onto the dielectric body of each capacitor between each of the conductive terminations thereof. Each of the electrical contacts of the connector is electrically attached to a respective one of the metallized openings of the substrate.

Method of making an electrical filter connector

An electrical connector for terminating shielded flat multi-conductor cable is divided. The connector includes a housing having a metal connector shell. A conductive clip is provided which engages in unison contacts of the connector associated with the ground conductors of the cable. The conductive clip also engages the metal shell of the connector housing. The conductive clip provides a ground reference for the connector and for the cable at its terminated end.

Electrical connector with grounding clip

Termination of flat cable is effected with connectors fed individually from a reel having a wound substrate with connectors releasably secured thereto. The connectors are seated in a crimping device and elongate such cable is fed to the crimping device along the cable longitudinal axis. Cable guide and registration apparatus is also disclosed, as is a control system.
