Apparatus and associated methods relate to an anti-rotation device (ARD) including a cylindrical ring extending along a longitudinal axis, the ring including proximal and distal faces. In an illustrative example, the ring may include proximal coupling members extending from the proximal face insertably engaging with mating recesses within a connector-disk. The ring may include distal coupling members extending from the distal face insertably engaging with mating recesses within a body-assembly, for example. The coupling members may extend, for example, parallel to the longitudinal axis. The ARD may be captured between the connector-disk and the body-assembly and may be retained by a proximal twist-lock cap screwably engaged with the body-assembly, such that relative rotational motion between the connector-disk and the body-assembly is substantially restricted, for example. Various ARDs may substantially restrict relative rotational motion between connector-disks and body-assemblies advantageously mitigating disconnection of wiring harnesses in circular connector applications.

The invention relates to an electrical connector socket configured to work operatively with a locking hub nut having a rounded top sidewall that does not damage the wiring during pulling, frees up manpower by allowing one person rather than two to be able to do the pulling, has a simplified design, and which has universal threading for conduit of all currently approved sizes and materials.

A ground block may include a metal ground plate and a ground wire fixedly coupled with the metal ground plate. The ground wire is configured to be non-detachable from the ground block during normal use of the ground block. The ground block may be formed by soldering, brazing, or clamping the ground wire to the metal ground plate.

A connector assembly comprises a first subassembly having a male contact and a first inner housing accommodating the male contact, a second subassembly having a female contact configured to be mated with the male contact and a second inner housing accommodating the female contact, a first connector, and a second connector matable with the first connector. The first connector has a first outer housing accommodating one of the first subassembly and the second subassembly and capable of accommodating both the first subassembly and the second subassembly. The second connector has a second outer housing accommodating the other of the first subassembly and the second subassembly and capable of accommodating both the first subassembly and the second subassembly.

In order to provide an environmentally secured voltage testing interface, an electrical enclosure box comprising a front panel is herein-described, into which is mounted a voltage indicator comprising a plurality of LED indicators that indicate a status of one or more circuits coupled thereto and monitored thereby. A compact test point device is also mounted through the front panel and comprises an interface comprising a plurality of external measurement sockets configured to receive one or more probes for manual measurement of voltages, wherein each external measurement socket is coupled to a voltage divider that is further coupled to each of a plurality of respective wires coupled to respective LED indicators.

A ground block may include a metal ground plate and a ground wire fixedly coupled with the metal ground plate. The ground wire is configured to be non-detachable from the ground block during normal use of the ground block. The ground block may be formed by soldering or brazing the ground wire to the metal ground plate.

Implementations of a two-piece electrical connector are provided. In some implementations, the two-piece electrical connector may be used to conductively connect two electronic devices (e.g., audio equipment). In some implementations, the two-piece electrical connector may be configured to reduce signal degradation (e.g., skin effect, noise, distortion, etc.) during transmission between connected electronic devices. In some implementations, the two-piece electrical connector may comprise a plug and a jack configured to connect together and thereby complete an electrical circuit. In some implementations, the plug and jack may each include two contacts. In some implementations, each contact is a segment of a foil conductor that is a single unitary piece of material (i.e., there are no breaks or soldered joints). In this way, through the use of foil conductors having a unitary construction, signal degradation is reduced between electronic devices connected together by a two-piece electrical connector.

A dismounting device for a cable for dismounting the cable from a wall includes a force receiving member, a sleeve member, an adapter member and a securing element. The sleeve member is mechanically connected to the force receiving member. Each of the adapter member and the securing element is mechanically connected to the sleeve member. The cable is connected to the wall via the adapter member in a mechanically dismountable manner. Furthermore, dismounting of the cable occurs by the flow of force from the adapter member via the securing element onto the sleeve member and from the sleeve member onto the force receiving member.

A grommet assembly includes, in one embodiment, a single-piece housing having an open top end, an open bottom end, an interior region, an interior wall surrounding the interior region and a housing outer surface. A receptacle support structure is located within the interior region and attached to the interior wall for supporting an electrical power receptacle. A bottom cover is attached to the housing at the open bottom end. The bottom cover includes sidewalls, an interior side facing the interior region of the housing and an opposite exterior side. The bottom cover is configured so that the sidewalls are located within the interior region of the housing when the bottom cover is completely attached to the housing. The grommet assembly further including a fastener operable to secure the housing at an opening formed in a work surface. The fastener includes an upper surface that is configured to engage a lower surface of the work surface.
