A device providing an enclosure for electronic components of an RF filter, trap, or the like for use in a CATV system. The device includes a hollow, cylindrical body portion with male and female headers at opposite ends with mutually engaged portions of the body and headers serving to rotationally lock the body and headers to one another. The mutually engaged portions comprise a pair of notches in each end of the body member and a pair of tabs on each of the headers which extend into the corresponding notches, the tabs and notches having substantially equal widths to prevent rotation of the headers relative to the body upon application of a torque, such as occurs when the devices are installed and threaded to an adjoining connector. In addition to the single body version, the invention is disclosed in a six-pole version having three body members arranged in successive, coaxial relation and rotationally locked to the headers at each end and to adjoining body members. In both versions, the body member(s) and header(s) are maintained in longitudinally assembled relation without the conventional induction soldering operation. In the first embodiment the body and headers are enclosed in a closely fitting sleeve having opposite ends which are formed over the peripheries of the headers. In the second embodiment, longitudinally adjoining members are joined by interference fit with a locking ring and groove to lock the inner body to the header.

A potted electrical circuit is enclosed within a housing and has a first and second fiberglass layer that is laid upon a top surface of the potted electrical circuit. A lid of the housing seals the electrical circuit there within and an opening formed in a side wall allows circuitry wiring to extend there from out. The first fiberglass layer is a woven layer while the second fiberglass layer is a padding-like layer. Circuitry wiring pushes through the woven first fiberglass layer before extending out through the opening in the housing. The first fiberglass layer is tucked in and around the electrical circuit and adheres to the inside of the housing by attaching to the potting material while it hardens. In a preferred embodiment, the electrical circuit in combination with the insulation material is used within a transient voltage surge suppression device.

An electronic filter comprises a housing having input and output ends. The housing has a body and a connector. The connector is located at the input end of the housing. A circuit board is located within the body. A collet assembly is located within the connector to receive electrical signals and conduct them to the circuit board. The collet assembly includes an insulator, a conductor, and an elastomeric sealing member. The insulator is located within the connector. The insulator contains a generally cylindrical opening through its length. The conductor extends through the opening of the insulator. The conductor has an input end adjacent the input end of the housing and an output end adjacent the circuit board. The conductor has a hollow interior at its input end. The sealing member surrounds the insulator in compressed engagement with the insulator and the surrounding connector.

A high-density pass-through filter apparatus slips over the terminal blade of a standard pass-through electrical connector within an opening in the bulkhead of an electronic module to which the connector is fastened. The filter apparatus retains a large number of axially oriented and axially terminated capacitive filter components which are electrically coupled at one end to the connector terminal and at the other end to a peripheral ring that resiliently engages the periphery of the bulkhead opening.

The bundle division unit is coupled to a protection member for protection and positioning purposes.

An interconnect system between an integrated circuit device and a printed circuit board may include a filter portion coupled to conductors on a power distribution bus. The filter portion may reduce radiated emissions produced during operation of the integrated circuit. The interconnect may include dispersive elements. The dispersive elements may be less electrically conductive of current in a higher frequency range than in a lower frequency range. In some embodiments, the second level interconnect may include a socket having dispersive contacts. The contacts may be coupled to core power conductors on the power distribution bus.

A filter design configured to operate in the medium voltage range of 1000 to 5000 volts, provides protection against Electromagnetic Pulse/High Altitude Electromagnetic Pulse (EMP/HEMP) intentional electromagnetic interference pulses. The filter utilizes no oil filled components to preclude the catastrophic failures (explosions) during operation. Many of the components incorporated in the present design are suited to absorbing harmonics without failing. In addition to mitigating E1 and E2 pulses, the filter is resistant to line harmonics which have proved to cause filter failure in past designs. The filter provides EMP/HEMP conducted pulse protection for downstream electronics inside hardened shelters for medium and high voltage applications.

Grounding elements are used to properly ground floor coverings and other elements whereby a floor covering, such as a carpet, need not be removed and reinstalled to correct a grounding problem. Properly grounded floor coverings and other devices reduces the effects of electrostatic discharge (ESD) and eliminates disruptive leak paths. One form of the invention has an element that is touched by a user layered on top of an ESD grounded work surface.

An exemplary over-voltage protection device used in an electronic device includes a housing capable of being grounded, a circuit board, a connecting member detachably attached to the circuit board and the housing to electrically connect the circuit board with the housing, and a protection member connected to the circuit board and circuitry of the electronic device. When an over-voltage is generated in the electronic device, the over-voltage is transmitted to the ground through the protection member, the circuit board, the connecting member, and the housing.

A filter for CATV applications includes a housing and two interface caps, each with an annular groove in a header portion thereof. A circuit board having a grounding bus along an edge of the board is disposed inside the housing. A split ring grounding clamp is disposed inside the housing such that a plurality of split rings are adjacent the grounding bus. The interface caps are press fitted into the ends of the housing, forcing the plurality of split rings into uniform contact with the grounding bus. The ends of the housing are then crimp-rolled such that a ridge is formed in the housing where the grooves in the headers are located in the interface caps, thereby sealing the ends of the housing to the interface caps.
