Abstract: A coaxial cable seizure assembly includes a stamped conductor with a leaf spring receptacle portion to provide a coaxial cable connection inside an HFC network device, such as an HFC node or amplifier. The stamped conductor portion is stamped from a single piece of metal and is located in an insulator portion. The insulator portion may be located inside a housing of the HFC network device adjacent a coaxial cable port such that the leaf spring receptacle portion is aligned with and receives a coaxial cable center conductor pin of a coaxial cable connected to the coaxial cable port. In one embodiment, a coaxial cable seizure assembly further includes a pin portion formed from the same piece of metal as the leaf spring receptacle. In another embodiment, a PCB-mounted coaxial cable seizure assembly further includes a PCB mounting portion formed from the same piece of metal as the leaf spring receptacle.

Abstract: An aspect of the present disclosure includes a node housing for use in a broadband distribution network that includes coupling the amplifier to a lid portion and providing an interface plate in a base portion that allows for RF and power signals to be provided to the RF amplifier within the lid portion. The interface plate disposed within the base portion further preferably provides power pass-through to downstream nodes that remains electrically connected even when the amplifier is decoupled from the lid portion. Thus, the amplifier and/or lid portion may be decoupled from the base portion without disrupting power distribution to the down-stream nodes.

Abstract: A lid assembly containing a lid gasket may be used to replace an existing lid assembly that forms part of a housing of an outdoor electronic device, such as an RF amplifier in a hybrid fiber-coaxial (HFC) network delivering CATV services to subscriber locations. The replacement lid assembly is configured to engage and cover an existing base of the electronic device, such as an RF amplifier, without disconnecting the electronic device (e.g., without interrupting CATV service). The lid gasket in the lid assembly may comply with current requirements and/or standards and is configured to engage the existing base adjacent an older gasket in the base to reinforce sealing of the electronic device housing. The lid assembly may also be configured to include improved or upgraded electronic components, such as an integrated power supply, and/or to provide improved heat transfer.

Abstract: A heat transfer device may be used to provide a thermal conduit from heat generating components mounted on transversely oriented circuit boards. The heat transfer device generally includes a base portion for supporting and thermally coupling with at least one heat generating component on a main circuit board and a transverse portion for supporting and thermally coupling with at least one heat generating component on a daughter circuit board that is oriented transverse to the main circuit board. The base and transverse portions may be made of a thermally conductive material with raised pedestals providing the thermal coupling with the heat generating components. The transverse portion of the heat transfer device may also be designed to facilitate connecting the daughter circuit board to the main circuit board. The heat transfer device may be used in an opto-electronic communications module, such as a broadband digital access (BDA) module used in a hybrid fiber-coaxial (HFC) network.

Abstract: The present disclosure is generally directed to an RF connector assembly for use within a node of a broadband distribution network, and can receive a center conductor pin of a coaxial cable, e.g., via insertion by a technician, and electrically couple the center conductor pin to circuitry within the node, such as an amplifier. The RF connector assembly preferably also securely physically couples to the center conductor pin via a spring-biased arrangement (and thus by extension securely couples the coaxial cable to the housing of the node) which can supply a bias force to the center conductor pin in response to insertion of the same into the RF connector assembly. This advantageously eliminates the necessity of opening the housing of the node to couple/decouple the center conducting pin of the coaxial cable to the node.

Abstract: The present disclosure is generally directed to a connector assembly that includes an increased outer diameter of the connector member relative to the equivalent G-type connector and an increased inner diameter of the receptable member relative to the equivalent G-type receptacle (also referred to as a seizure nut) to achieve higher current carrying capacity and target frequency rates of up to 3.0 Ghz, for example. In one preferred example, this results in a connector assembly consistent with the present disclosure having a connector member with an outer diameter of at least 10.70 mm, and more preferably 10.76±0.01 mm, rather than the 9.4 mm diameter of existing G-type connectors. Despite this increased diameter, a seizure assembly consistent with the present disclosure can achieve a functional impedance of 75 ohms to maintain nominal signal quality.

Abstract: A coaxial seizure assembly is disclosed that includes an integrated mechanical stop that prevents over-insertion and maintains a nominal/expected impedance value to enable high-frequency switching, e.g., 1.8-3 Ghz or greater. In more detail, the coaxial seizure assembly includes a coaxial receptacle defined by an opening configured to at least partially receive and couple to a coaxial connector. The opening communicates with a seizure cavity defined within the coaxial seizure assembly. A radio frequency (RF) interconnect at least partially extends into the seizure cavity, with the RF interconnect having a first end to electrically couple to an electrical component and a second end that extends a predetermined angle relative to the first end, e.g., substantially 90 degrees. The second end defines a mating surface that aligns within the seizure cavity such that an imaginary line drawn along an insertion path of a coaxial cable conductor pin intersects with the mating surface.
