An electrical connector is made repairable by providing a front insert which is removable from and retained in the shell by an O-ring. The shell includes an undercut in which the O-ring is mounted, and the insert includes a circumferential elliptical groove. In use, as the insert assembly is inserted into the shell, the O-ring mounted on the undercut of the shell is compressed by the insert until it reaches the groove, whereupon it expands into the groove in a direction parallel to the direction of insertion, which constitutes the major axis of the elliptical profile of the groove, and thus provides positive retention and sealing without the need for additional retention mechanisms. Removal is facilitated by a removal tool which includes hooks extending from a front circumference of a sleeve of the removal tool. The hooks are inserted through slots in the insert and past a collar provided around the mating interface of the insert. The tool is then rotated a short distance to cause the hooks to engage a back surface of the collar, while a piston provides a biasing force to lock the insert against the connector during removal.

System for repair of a repairable connector

A capacitor array for filter connectors includes a stamped and formed ground resilient metal plate. Integral tines are provided to establish a solderless electrical connection between the plate and a connector shell. The filter elements are discoidal capacitors having cylindrical inner and outer electrode portions. The filter assembly is completed by soldering the outer electrode portions to the ground plate, while a solderless electrical connection between the inner electrodes and the feedthrough contacts of a connector is established by providing compliant sections on the contacts. A pi filter array is formed using two of the ground plates.

A modular electrical connector assembly includes a shell containing a plurality of separate bays, each bay being adapted to accept an EMI/EMP electrical connector insert or module. A unique latch structure enables each connector module to be easily removed from its bay to enable fast and easy replacement of defective modules or the EMI/EMP components contained therein.

A transient suppression component includes a lead assembly adapted to permit in-line installation in a connector contact. One lead surrounds the other and is cylindrical for connection to the aperture tines of a connector ground plate. The other lead carries electrical signals between mating portions of the connector contact assembly. A transient suppression component body is connected between the feedthrough lead and the cylindrical ground lead. The feedthrough lead can be made from a single stamped piece of metal formed to include a component mounting section which substantially encloses the component.

Transient suppression component

A transient suppression contact assembly, capable of low working voltages and high energy handling capacity, including lightning suppression, employs a multilayered varistor as the transient suppression device. The varistor is mounted in a notch in the contact and connected to ground via a ground sleeve. An insulator sleeve separates the ground sleeve from the contact, and both the insulator sleeve and ground sleeve include a gap or groove extending the length of the sleeve to permit the sleeves to be snapped onto the contact and aligned without the need for additional adhesive staking operations.

High density MLV contact assembly

A transient suppression connector includes a plurality of contacts each of which carries both a negatively and a positively biased diode. The connector also includes negative and positive bias voltage input pins and a grounding arrangement including a respective common diode for the negatively and the positively biased contact diodes.
