A pre-wired management fastening device, including a tubular part composed of an integrally formed upper tubular party and a lower tubular part. An included angle is formed between the upper tubular and the lower tubular. Inside the tubular part has a channel. The front end of the tubular part has a cable clamping mechanism. The rear end of the tubular party is locked on the inlet of the electric plug connector or electric plug slot. It is convenient for the construction of on-site personnel, which makes the wiring of the cable more beautiful and reduces the difficulty of construction.

An electrical connector includes an insulative front housing, an insulative rear housing and a plurality of contacts. The front housing forms a mating cavity. The contact includes a contacting section extending into the mating cavity, a retaining section retained to the front housing, and a connecting section connected with the wire. The rear housing includes a front receiving space and a rear receiving space communicating with each other. The rear portion of the front housing is assembled into the front receiving space of the rear housing to have the connecting sections of the contacts exposed in the front receiving space. The rear receiving space receives the corresponding wires therein with corresponding opening to allow the wires to extend therethrough.

Systems, devices, and methods for drain cleaning using high voltage, high frequency AC electrical power supplied through a video push-cable are disclosed. In one embodiment, a drain cleaning system may include a cable for carrying electrical control and/or data signals as well as alternating current (AC) power at a high voltage and high frequency relative to AC mains frequencies.

The cable assembly may include a first wire assembly. The first wire assembly may be connected to a first connector and a second connector. The first connector may include a shell and the shell may include an extension. The extension may extend away from the rear of the connector. In one embodiment, the extension may be integral with the shell. The extension may include one or more openings. The first wire assembly is bent in a controlled manner at first bend. The first opening in the extension maintains the first wire assembly in the bent position to maintain control of the radius in first bend. The radius is controlled to allow the first wire assembly to fit in a small space.

A backshell is configured to be connected to an electrical connector. The backshell includes a backshell body configured to receive a cable connectable with the electrical connector. The backshell also includes a fixed tail portion extending from the backshell body. The fixed tail portion provides a plurality of different connection positions spaced along a curved exit path extending from the backshell body. A fastening component can be connected to the fixed tail portion to retain the cable to the fixed tail portion at one of the plurality of different connection positions. The connection positions include fastening component engagement means, configured to retain the fastening component in position longitudinally with respect to the curved exit path. Connection of the fastening component at the different respective connection positions guides the cable from the fixed tail portion at different respective exit angles.

A rotatable interface assembly for an electrical connector, an electrical connector, a connector system, and a method for coupling the system is presented herein. The rotatable interface assembly includes a connector component, having an electrical contact for electrically connecting electrical elements via a corresponding counter connector. The rotatable interface assembly further includes a base part and a rotatable part. The base part at least partially houses the connector component and has a securing means for being secured to a fixed counterpart. The rotatable part being configured to receive the corresponding counter connector at least partially under a specific angular orientation. The rotatable part is arranged on the base part, so as to be rotatable around a rotational axis relative to the base part. The rotatable part can be rotated around the rotational axis in a desired angular orientation that matches an orientation of a corresponding counter connector, to allow to receive the corresponding counter connector under different angular orientations, relative to the base part.

An electrical cord includes a housing with a cavity and a connector rotatably connected to the housing. The electrical cord also includes a strain reliever connected to the housing and a cable connected to the connector. The cable extends through the cavity and connects to the strain reliever.

An illustrative example embodiment of a connector shell includes a connector cover and a cable-guiding sleeve having a curved conduit. The cover and the cable-guiding sleeve are made up of two separate elements. The cable-guiding sleeve is mounted on the cover so as to be rotatable about an axis of rotation. The cable-guiding sleeve and the cover comprise means for blocking the rotation of the cable-guiding sleeve on the cover in at least two different pre-set angular positions about the axis of rotation. These blocking means comprise shapes that engage with each other in a complementary way, and that are able to release each other and allow the passage from one angular position to the next.

A waterproof connector includes a housing including a first tubular portion forming a first end of the housing and a second tubular portion forming a second end of the housing, an inner member to hold a terminal, a seal member having a wire insertion hole, the seal member being to be attached to the second tubular portion at the second end of the housing and a filler filling a space inside the housing and between the inner member and the seal member. The housing has a bent structure. The second tubular portion includes a recessed portion on an inner peripheral portion on a side where an inside corner of the bent structure of the housing is provided. The seal member includes a protruding piece to be fitted into the recessed portion when the seal member is attached to the second tubular portion.

An electrical plug connector terminates a twisted pair electrical cable. The electrical plug connector includes a base and a plug housing holding electrical contacts therebetween. The base includes a divider structure including separation walls. At least one of the separation walls defines an abutment surface against which a forward end of the electrical cable abuts when terminated by the electrical plug connector. The plug housing defines slots so that the electrical contacts are accessible. The electrical plug connector axially secures an outer jacket of the electrical cable against rearward movement relative to base. The at least one separation wall inhibits forward axial movement of the outer jacket of the electrical cable relative to the base.
