Abstract: An RF connector assembly has a first connector housing with a first end constructed for connectably receiving a terminal end for a first coaxial cable and a second connector housing with a first end constructed for connectably receiving a complementary terminal end for a second coaxial cable. The terminal end and complementary terminal end are complementarily constructed for engagement to each other. The first and second connector housing are constructed at their respective second ends to connect to one another. The first connector housing receives a tubular shield mounted about and connected to the respective terminal end. The tubular shield has a set of resilient radially inwardly extending contact fingers for electrically connecting about the complementary terminal end when the second connector housing is connected to the first connector housing.

Abstract: A passive low pass, &pgr;-type filter of a surface mounted device configuration has two stack capacitors disposed radially inwardly of a coil, otherwise known as an inductor. Each capacitor has a number of ground plates successively stacked between a number of signal plates. The ground plates electrically engage a front and rear ground band which circles the external surface of a non-conductive encapsulant of the filter. A forward and rearward conductive member or sheet engages each end of the encapsulant. One end of the coil is engaged to the front sheet and the opposite end is engaged to the rear sheet. The signal plates of the forward capacitor are engaged to the front sheet and the signal plates of the rearward capacitor are engaged electrically to the rear sheet.

Abstract: A passive low pass filter of a surface mounted device configuration has counter-wound coils and at least one capacitor. Each coil has a centerline. The centerlines are parallel to one-another and perpendicular to a plurality of plates of the capacitor. The windings of the coils and the plates of the capacitor are encased in a dielectric encapsulant.

Abstract: An EMI filter (10) that makes use of a ferroelectric-ferromagnetic composite, member, or slab (12) in connection with capacitive and inductive elements. The geometrical structure of the filter (10) is such that the mutually orthogonal electric fields and magnetic fields generated by the capacitive and inductive elements penetrate the volume of the composite (12). In some designs, capacitive plates (14, 18, 32, 34) are split to avoid setting up eddy currents in the plates (14, 18, 32, 34) which oppose the penetration of magnetic flux through the composite (12). Various structural designs can be provided to define the capacitive elements and the inductive elements in different configurations relative to the composite to satisfy the desirable requirements.

Abstract: An ignition cable terminal assembly connects an ignition cable to a stud terminal of a spark plug. The assembly includes a metal sleeve that has a crimp barrel at an upper end, an intermediate compression ring, a lead-in below the compression ring and an inwardly directed stop ring below the lead-in. A lock sleeve inside the metal sleeve, has a plurality of spaced longitudinal channels in an inner cylindrical surface that communicate with an annular cavity at an upper end. The longitudinal channels include lock channels that have lock ledges at the cavity and release channels between the lock channels. Upper and lower ring gears are inside the lock sleeve. The lower ring gear engages the top of the stud terminal and has radial teeth that slide in the channels of the lock sleeve.

Abstract: A spark plug is provided which is suitable for use in a spark ignition system for an internal combustion engine. The spark plug is equipped with a specially configured firing tip on each of its electrodes for the purpose of minimizing the demand voltage of the spark plug, as well as extending the life of the spark plug by maximizing the time over which the demand voltage will remain within an acceptable level. For this purpose, the firing tips are configured such that their firing surfaces include at least three edges and three corners which serve as arc initiation sites of a relatively low resistance arc path between the electrodes.

Abstract: A spark plug boot assembly for interfacing an ignition signal conductor and a spark plug, the assembly including a spark plug boot having a hollow electrically conductive cylinder disposed on an interior boot surface, the cylinder having a flared lower cylinder end extending through the interior boot surface over a spark plug post-socketed terminal contact area, and having an upper cylinder end extending over the socketed terminal including over any crimp section of the socketed terminal. The cylinder further includes a seat for seating a collar about the socketed terminal when a full terminal insertion position is reached.
