The electrical connector comprises a housing having contact receiving passages with contacts disposed therein. Recesses are disposed along a mounting face of the connector and are defined by walls therealong. The recesses are in communication with the contact receiving passages. A rigid ground bar is disposed along sidewalls of the housing. Chip capacitors are positioned in the recesses to have one electrode electrically connected with the contact and the other electrode to be electrically connected with the ground bar. The chip capacitor provides a low impedance pathway for EMI from the contact to the ground.

An electrical overstress protection apparatus and method includes the provision of an overstress element (22) comprised of a lamination including a conducting ground path (26) and a dielectric sheet (30) engaging discrete signal paths (16) connected to contacts (44), the sheet (30) containing holes (32) or pores or thread or fiber interstices filled with an electrical overstress protection material (36) with the sheet thickness and hole area in conjunction with area of signal and ground paths and characteristics of the material adapted to provide breakdown and clamping voltages via a path to ground from signal contacts to ground to protect components from excessive voltage levels. Electrical connectors (40,40', 40') incorporate the apparatus in different embodiments of housing (42,42') and contact (44) configurations.

The filtered tap connector 10 includes a body member 12, having a pair of contact members 40 secured therein; a pusher member 50 receivable into a large recess 18 of the body member 12, the pusher member 50 having wire engaging surfaces 52 adapted to engage portions of wires 92 and urge them into electrical engagement with contact members 40; a pair of electrical components 60 of the type having a pair of spaced exterior electrodes 62, 64 disposed within cavities 26 of the body member 12 such that one of the component electrodes 62 is engaged with the corresponding contact member 40; and a biasing member 70 securable to the body member 12 remote from the large recess 18 and including a pair of arm portions 82 for engaging respective ones of the second 64 of the pair of electrodes 60, the biasing member 70 including a conductive path extending from component engaging surfaces 84 to an exposed outer surface portion and means for maintaining the biasing member 70 in the closed position. A pair of wire receiving channels 24 extend through the body member 12, along an inner-most surface of the large recess 18. Wire receiving sections 46 of the contact members 40 project outwardly into the large recess 18 transverse of the wire receiving channels 24. The biasing member 70 is movable between open and closed positions with respect to the body member 12.

An electrical connector assembly (10) includes a plurality of signal contacts (22) and a grounding structure (16) mounted in a plastic housing (12) having flat exterior surface portions (19). One or more filter elements (32) contain signal electrodes (34) associated with and electrically connected to respective signal contacts (22) at staggered signal connection sections (35), with ground electrode (38) connected to grounding structure (16) at section (39). Each filter element is in tape form with dielectric material (36) laminated between broad area electrodes (34,38) with the tape attached to the housing exterior surface (14) for the electrodes (34,38) of the filter to be connected between the signal contact and ground structure to effectively insert the filter in the signal path to ground. Each signal electrode (34) may be carried on a separate tape filter, or one tape filter (80) may define at least two signal electrodes (82,84).

A device (24) for protecting against electrical over stress (EOS) of electrical components includes first contacts (50, 56) that interconnect to signal contacts (18) of a connector (12) and second contacts (68) that connect to the ground circuit (20) of a connector with a rigid plastic housing (26) holding the device contacts so that ends (55, 65) have a precise spacing gap (71), the gap being filled with a material matrix (72) of insulating and conductive materials having characteristics in conjunction with the gap to define transit voltage suppression by grounding the signal contacts of a connector. The device is made bendable to fit onto connectors and conform to the connector geometry.

Electrical over stress device and connector

An electrical connector adapted to protect its signal circuits against power surges for at least ESD protection, having a conductive shell (60) with a transverse flange (64) on which are mounted components such as diodes (100) having first electrodes soldered thereto for grounding. A plurality of discrete straps (114) extend from second electrodes of the diodes to respective the contacts (20) and define circuits electrically connecting the contacts to the diodes. The dielectric housing (30) includes slots (46) along side surfaces within which the straps are retained, and a lateral housing flange (42) has recesses (54) within which the diodes are disposed. The method of fabricating the connector includes providing on at least a portion of each strap (114) a thin second layer (152) of magnetic material which in conjunction with the nonmagnetic copper layer (150) defines a self-regulating temperature heater when subjected to RF current, to reflow solder to join to and electrically connect the diodes (100) and contacts (20).

A transient suppression device for use in an electrical connector is disclosed. The device is comprised of a dielectric substrate means having conductive path means thereon, electrical terminal means disposed on said substrate means and transient suppression means for electrically connecting said electrical terminal means and said conductive path means. Said device suppresses voltages outside a specified level as they are conducted through said terminal means thus protecting the connector from power surges.

Locking clip pin extender

A RF-EMI filter for circuit boards is formed by a through pin terminal having a filter sleeve mounted thereon and a ground pin with an eyelet portion formed about the filter sleeve with a leg depending normal to the axis of the sleeve. The ends of the through pin are formed parallel to each other and to the ground pin leg. The filter sleeve, and its immediate environment, are encapsulated in an insulative material. The thus formed three legged filter can be applied to a circuit board along with the other components to be fixed thereto.
