Abstract: A planar filter array includes a single monolithic alumina substrate having a plurality of counter bores on each side connected by central bores to form passages for insertion of connector pin contacts. The connecting bores contain ferrite beads and the counter bores contain discoidal capacitors which sandwich the ferrite beads to form pi filter circuits for filtering the pin contacts. Grounding electrodes on the discoidal capacitors are soldered to a grounding layer or traces on the substrate to provide a ground path for the fiters.

Abstract: A connector assembly allows rear repair/replacement of monolithic capacitors as a result of a frictionally mounted insert assembly being retracted from the rearward end portion of the shell.

Abstract: An electrical connector assembly having means for protecting its contacts from adverse voltage surges includes protectively terminating one terminal of a silicon diode within a notch formed in the contact and the other terminal with a conductive sleeve encircling the contact body but spaced therefrom. The conductive sleeve is in releasable engagement with a plurality of conductive spring fingers which are integral with a conductive grounding plate whereby a ground path is established between the connector shell and the contact without stressing the diode or its terminations.

Abstract: A filter connector having a metal shell, a contact mounted in the shell for passing a signal therethrough, a filter element and a silicon diode mounted on the contact and in electrical circuit relation therewith, and ground means for grounding the contact to the shell, the silicon diode for preventing voltages from passing which exceed a predetermined value.

Abstract: An electrical connector shell has a monolithic ceramic capacitor having active and ground electrodes for filtering contacts received in plated passages therethrough, and a grounding ring for grounding the contacts to the shell. A ceramic substrate is bonded to or extends integrally from a top face of the monolith, the substrate including a plated bore extending inwardly from its top surface, and a metal spring ring being disposed in the bore, each bore being axially aligned with one plated passage to complete an circuit path between the contact and the active electrodes and provided to eliminate stresses which could crack the fragile monolith. The grounding spring is characterized by a cylindrical metal annulus including angularly spaced foils at acute angles thereto, each foil being pivotably connected and completing a circuit path between the ground electrodes and the connector shell.

Abstract: An electrical connector having means for protecting its terminals from transient voltages includes a selectively plated cavity endwall in a substrate being laterally offset from its respective terminal receiving passage, a silicon diode being mounted in the cavity and connected to a conductive spring, and ground paths completing a conductive circuit between the terminal, the endwall and the connector shell, the spring completing an electrical ground path through the diode for overvoltages to be diverted from the terminal to the shell ground.

Abstract: A cylindrical diode is terminated to a contact and mounted in a cylindrical countersunk recess of a dielectric insert mounted in a metal connector shell, the connector having an arrangement for grounding the contact to said shell. The diode has a first electrode defining a top face generally coplanar with the insert, a second electrode defining a bottom face, a silicon chip sandwiched between the electrodes, and a circular hole extending between its end faces and circumposed around said contact.

Abstract: This invention relates to electrical connectors used between bulkheads and more specifically to a hermetically sealed connector having a removably mounted electrical filter assembly (10). The connector is characterized by a metal connector shell (1) having a plurality of electrical contacts (2) hermetically sealed (3) and mounted within the shell (1), and an electrical filter assembly (10) removably mounted (4, 5a, 11) and electrically connected to at least one of the contacts (2) and shell (1).

Abstract: An electrical connector having a plated plastic grounding insert (12) providing an electrical connection from a grounding electrode (18) to the connector shell (14) the ground insert (12) including integral spring fins (22) extending diposed about the periphery of the insert and extending from a rear face thereof compressibly received within a bore (26) in the connector shell (14). Grounding towers (30) are also formed integrally with the grounding insert (12), including a generally conical proturbance (30) extending from the front face of the insert with slots (32) providing resiliency for friction engagement of the grounding electrode (18). The grounding insert (12) and contacts (16) are supported by encapsulating material (36, 38) disposed on either side of the insert (12). The insert (12) is coated with a cnductive layer such as metallic silver to enable establishment of the electrical connections.

Abstract: A filter connector is disclosed with an adaptor member (14) which permits removal and replacement of the filter connector member (10) without individually disconnecting and reconnecting the wires (16). The filter connector member (10) is provided with a plurality of filter contacts (22) each having a mating end (pin 26) at the forward end and a mating end (pin 28) at the rear end. A filterless connector member (12) includes plural filterless contacts each having a wire receiving end (74) and a mating end (socket 72) adapted to mate with the pin (26) of the corresponding filter contact (22). An adaptor member (14) includes a plurality of filterless contacts (42) each having a wire receiving end (90) and having a mating end (socket 88) adapted to mate with the pin (28). The filterless contacts (42) in the adaptor (14) are individually removable and replaceable in the event of a malfunction in these contacts.
