A device for use with coaxial cable to attenuate sheath currents associated therewith. The device is adapted to be coupled to incoming and outgoing coaxial cables and includes a ferrite core configured as a first hollow cylinder mounted coaxially within a housing configured as a second hollow cylinder. A conductor within the housing has opposite ends positioned for electrical contact with the incoming and outgoing coaxial cables and an intermediate portion passing through the ferrite core longitudinally at least twice, being passed back over the outside surface of the core between passes therethrough. The elements are so dimensioned that the outside diameter of the housing is less than one inch, thereby allowing side-by-side mounting of a plurality of the devices on industry-standard, multi-port taps which have center-to-center spacings of one inch.

An F-type connector for mounting to a prepared terminal end of a coaxial cable for threaded engagement of a nut on the connector to a threaded shaft at a port on video equipment to which the coaxial cable is to be electrically connected. In the connector of the present invention, the nut is mounted for limited axial movement with respect to the post, body and compression ring. A coil spring biases the nut toward a rest position with respect to the other elements wherein not more than three revolutions of the nut into engagement with the shaft are necessary in order to bring the post of the connector into contact with the shaft on the equipment, providing a satisfactory coupling. Upon further revolution of the nut, the post and shaft remain in contact as the nut moves axially away from the rest position with respect to the other elements.

The present invention provides an over-voltage surge protection device comprising a printed circuit board having a signal carrying conductive member having a plurality of nodes positioned therealong, and a conductive member running to ground also having a plurality of nodes positioned therealong. The nodes on the signal carrying member and ground member extend along a common path with corresponding ones of the signal carrying nodes positioned in adjacent, but spaced relation to the ground nodes. Preferably, the nodes are shaped in the form of triangles due to this particular geometry's favorable ability to accumulate and discharge voltage.

A cable connection assembly comprising a moisture migration prevention component located entirely within a nut component, and a threaded actuator integrated entirely within the nut component of said assembly, wherein upon attachment of the nut component onto a threaded port, the threaded actuator engages the threaded port, wherein upon an initial actuation of the nut component, the threaded actuator axially advances to a partially engaged position and axially advances the moisture migration prevention component, wherein continued actuation of the nut component further axially advances the threaded actuator to a fully engaged position and compresses the moisture migration prevention component to exhibit moisture migration prevention at a location external to a plurality of threads of the threaded port engaged within said connection assembly is provided. An associated method is also provided.
摘要:
An integrated filter connector apparatus that performs the functions of a coaxial cable connector component combined with the functions of an in-line signal conditioning component. The apparatus eliminates at least one exposed point of connection between a separate coaxial cable connector component and an in-line signal conditioning component. Elimination of such a point of connection likely reduces RF ingress into a signal path and likely reduces interference with a signal traveling through the signal path. Embodiments of the connector apparatus provide various types of connector interfaces.

An integrated seal assembly is provided, as is a coaxial cable system component incorporating the seal assembly with a connector for coupling to an externally threaded port. The seal assembly includes a bellows-type seal formed at least partially of a conductive elastomer and having an elastically deformable tubular body and a plurality of sealing surfaces, and an integral joint-section intermediate an anterior end and a posterior end that assists in the axial deformation of the seal in response to axially-directed force. One of the sealing surfaces engages a corresponding surface of an internally threaded nut or housing. The component is engagable with an externally threaded port via the internally threaded connector. The anterior end of the seal fits over the port and a sealing surface of the seal is capable of sealing axially against a shoulder of the port while the seal body covers the otherwise exposed externally threaded port. Upon tightening of the nut on the port, the seal deflects in the axial direction to accommodate a variety of distances between the connector and the shoulder of the port. Additionally, the seal is capable of expanding to allow a second sealing surface to contact and seal against a variety of smooth outside diameters of the port. The versatility of the seal allows an operator to use one connector of a system component on a wide variety of externally threaded ports without the risk of a faulty seal at the connection or a poor connection due to an improper seal.

An upstream bandwidth conditioning premise device for use as part of a CATV system and for placement on or near a user's premise to reduce noise created on the user's premise that would otherwise be injected into upstream transmission channels and passed into an RF main signal distribution system of the CATV system. The device includes a variable attenuation device, a signal measurement circuit, a memory circuit and an electronic circuit, which is configured to iteratively determine (i) whether an incremental amount of additional attenuation is to be applied and (ii) whether at least a portion of a previously applied incremental amount of attenuation is to be removed. The electronic circuit includes a counting circuit, a threshold comparison circuit configured to compare a peak signal strength to a predetermined threshold, and a peak comparison circuit configured to compare a contemporary peak signal strength to a previous peak signal strength.

A downstream bandwidth output level and/or output level tilt compensation device that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes a tuner that identifies low and high band signal channels, and a channel analyzer that determines a format of each of those channels. A signal measurement measures low and high band signal strengths. An offset circuit adds or subtracts an offset value to the low and/or high band channel signal strengths depending on whether the respective channel is analog or digital. A microprocessor compares the low and high band signal strengths, including any offset values, to a predetermined signal strength loss curve. A variable output level compensation device and a variable slope adjusting circuit are provided to amplify and adjust the gain slope of the downstream bandwidth.
