Abstract: A connecting port assembly of an electrical device comprises an internally threaded female port formed from a portion of a housing of an electrical device, where the female port is configured for threaded engagement with an externally threaded male coaxial cable connecting element.

Abstract: A female connector assembly for an electrically conductive coaxial cable, comprises an electrically conductive barrel shaped body having a top end with a centrally located hole forming an input port, and a bottom end configured for connecting with a portion of a housing of an electrical device. An electrically insulative hollow sleeve consisting of two interlocking cap members encloses an electrically conductive clip pin, and is contained within the body of the connector. The sleeve and clip pin are securely held within the body via connection of the body to a housing of an electrical device, and rigid attachment of an elongated pin extending from the sleeve, through a hole in the housing, to electrical circuitry within the housing.

Abstract: A multi-tap 2 has two compartments 4,6, the first including input ports 46,48 for conducting RF signals (RF) and AC power (AC), a microstrip 206 for conducting the RF and AC from input ports 46,48 to a conductor 62 passing through a passageway 64 between compartments 4,6 for passing the RF and AC to the microstrip 206 in the compartment 6. The latter microstrip 206 conducts the RF and AC to output ports 78,82 at an end of the compartment 6 in a first operating configuration. In a second operating configuration, a wire 80 conducts RF and AC away from the output ports 78,82 to a microstrip 90 for conducting the RF and AC to a wire 94 passing through a passageway 96 between compartments 4,6 for further conducting the RF and AC to a microstrip 102 in compartment 4 to divert the RF and AC to alternative ouput ports 84,86 of compartment 4.

Abstract: A hermetically sealed female connector for a coaxial cable, includes a barrel-shaped brass housing enclosing in the order given from a top end providing an input port to a bottom end, a rubber boot having a center portion partially protruding from a central hole in the top end, a first cap having an upper portion within the boot and a lower portion, a second cap having an upper portion contained within the lower portion of the first cap, the second cap also having a lower portion with a top edge abutting against the bottom of the first cap, a rubber washer with a top face abutting against the bottom of the second cap, a plastic washer with a top face abutting against the bottom face of the rubber washer, and a clip pin secured in the central longitudinal portion of the housing between the input port and the bottom end with an end of the clip pin protruding out of the bottom end of the housing, the bottom end of the housing being peened over to retain the connector components under compression for causing the

Abstract: In junction boxes for coupling T.V. signals and low frequency power waves on a coax line to a plurality of users, the T.V. signals are coupled via connections in a first compartment to a plurality of coax cables, and the low frequency power wave are coupled via low pass-filters to IDC connections in a second compartment.Leads from users are passed through a chamber on the wall of the second compartment containing a self-healing, self-supporting insulating substance and attached to the IDC connectors. The IDC connectors permit the lead to be paired through them so that an installer can know when the leads are properly partitioned.

Abstract: A tool is described for shunting a multi-tap for an RF cable system by connecting a low-pass filter between an unused input port and an unused output port of the multi-tap. The components of the filter are such as not to interfere with the circuits of the multi-tap when both are in the circuit. A light is provided for indicating when the tool is in operative position.

Abstract: A multi-tap is described having two compartments, a microstrip in each compartment for conducting RF signals and AC power from an input at one end of the multi-tap to a first output port at the other end, a cover for each compartment having a circuit thereon that is substituted for the microstrip in a compartment when the cover closes that compartment, a device near the first output port that can be adjusted to direct RF signals and AC power passing through the microstrips to a point other than the first output port and additional microstrips for conducting RF signals and AC power from that point, when the RF signals and AC power are present thereat, to a second output port located near the input port. Grounding shields are provided for shorting the additional microstrips when the device is adjusted to deliver RF signals and AC power to the first output port. When the cover of a compartment is closed, it activates a switches formed in part by ends of the microstrips.

Abstract: A multi-tap device for tapping a main TV or rf signal to deliver attenuated signals to individual TV receivers includes a pair of socket assemblies for receiving input and output pins of a plug-in tap plate or printed circuit board carrying necessary attenuation/tap off circuitry. The socket assemblies connect the input pin to a main input cable for receiving the main rf signal and ac power, and connect the output pin to a main output cable or continuation of the main cable, for distributing the main rf signal(s) and ac power to cascaded down line multi-tap devices. A shunt printed circuit board is mounted between the socket assemblies, and has an rf/ac conductive strip for connection at either end to switches built into each socket assembly.
