  • Patent number: 5046968
    Abstract: The invention facilitates individual selection and even field replacement of individual component-carrying contacts in a multicontact electrical connector. On a modular circuit-by-circuit basis, each circuit can be individually guarded against overvoltages, undesired frequencies, etc.; and in event of damage to a protection component, the protection can be easily renewed for any individual circuit in just a few minutes. An overvoltage-bypassing diode or other electrical component is positioned within a central cavity that extends axially within the body of a cylindrical contact--i.e., either a male pin or female receptacle. The component is oriented axially in the cavity. Because the bypassing component is physically protected within the cavity, it is much less vulnerable to physical and electrical damage in installation and service than in prior component-carrying contacts.

Rubber mounting blocks are positioned on the filters and pins to each side of the ground plane and the conductive rubber gasket and are placed under compression by housing members to cause an electrical interconnection between the filters and the ground plane through the gasket while absorbing any shock that may be imparted to the filters from the pins. The housing members are identical and are provided with polarizing means, latching means, and the like, as necessary.

  • Patent number: 4265506
    Abstract: A filtered connector assembly is disclosed for retrofit insertion between a mated connector pair, or for use in original equipment design. The assembly comprises a ground plate having a plurality of filter pin members mounted therethrough, hermaphroditic mounting plates assembled to alternate faces of the ground plate, and dielectric insert members received within profiled portions of each mounting plate for electrically insulating the filter pin members disposed therein.

  • Patent number: 4242655
    Abstract: A coaxial RF connector adapted for mounting on a wall of a utilization device, such as a video disc player, employs a capacitor for providing DC and low frequency blocking between the wall of the device and the outer conductor of the connector. The capacitor is formed in the shape of a washer to provide a uniformly distributed capacitance around the outer conductor.

  • Patent number: 4212510
    Abstract: An improved filtered header or feedthrough connector is disclosed for retrofitting filtered terminals into an existing electronic circuit. Each of a plurality of terminals is provided with filter sleeves which are soldered thereto. The filtered terminal assemblies are inserted into a header housing in a fixed array. At least one conductive rubber gasket on the housing interconnects the filters to a ground plane. A metal bushing can be mounted on the conductive rubber gasket to make an interconnection with mounting means, such as a bulkhead. The elastomeric ground plane engages the filters in such a manner as to apply a biasing force to the filters without creating such a high force that there would be a possibility of destroying the filters. The header housing also allows for accommodating filters of various sizes as well as for having terminal pins pass straight through without any filtering.

  • Patent number: 4195272
    Abstract: A multiple contact filter connector capable of accommodating high RF currents and a method of manufacturing the same are disclosed. The connector includes an outer metallic shell, a dielectric body within the shell and at least one network filter contact assembly. The inner body has at least one through channel and a transverse cavity which communicates with the shell and the channel. The network filter contact assembly has a ground electrode and a pin electrode and is disposed within the portion of the channel bridging the cavity. Conductive curable filler material is charged into the cavity around and in contact with the ground electrode to efficiently and inexpensively establish a ground plate for the connector. A retention means disposed within the channel and a locking means carried by the contact cooperate to provide axial strain relief, thereby protecting the bond between the conductive filler material and the ground electrode.

  • Patent number: 4187481
    Abstract: This disclosure relates to an EMI (Electro Magnetic Interference) filter connector which can be installed in the line between mating plugs and sockets normally used for terminating multiple conductors. This connector is used in an electronic equipment chassis or at a bulkhead junction box or, if necessary, between mating connectors in a cable run, where the metallic parts of the cable connector can be grounded. Conductive rubber or co-polymer elastometric washers are used to protect RF filter components in the connector from damage due to external stress. A high degree of EMI attenuation is provided by an integral metallic baffle having close fitting conductor holes which is located within the connector body.
