Abstract: A connector for a cable has an outer housing, an inner housing at least partially received within the outer housing, a strain reliving attachment mechanism, and a rotational locking mechanism. The strain relieving attachment mechanism has an assembly path with an preliminary mating position and a final mating position. The rotational locking mechanism is engaged with the strain relieving attachment mechanism along the assembly path from a locking position located between the preliminary mating position and the final mating position. The rotational locking mechanism couples the inner housing to the outer housing in a rotatory locked manner upon engagement with the strain relieving attachment mechanism.

Abstract: A high strength electrical connector includes an outer cylindrical, rigid support cover open at both ends and preferably comprised of a high strength metal. A first electrical lead extends through a tension bushing attached to one end of the support cover. A mating receptacle through which a second electrical lead passes is securely attached to a second opposed end of the support cover. Electrical connection between the ends of the first and second electrical leads is established within the support cover. Securely attaching the ends of the first and second electrical leads together within the support cover, which is preferably comprised of a high strength metal, directs axial and transverse forces exerted on the first electrical lead through the support cover, thus bypassing the electrical connection.

Abstract: Explosion proof enclosures and explosion proof connectors and sensors are used to render a machine, intended to be operated in an explosive environment, explosion proof. An explosion proof connector includes an intermediate section having an input portion to receive a cable from a terminal external to an explosion proof enclosure and an output portion for passing the cable for connection to a terminal within an explosion proof enclosure. A sealing tube which extends between the input and output portions has a central opening for enabling a cable to be passed through. A sealant may be injected into the sealing tube to form an air tight connection between the cable and the inner walls of the sealing tube which inhibits a hazardous condition from passing through and around the sealing tube. An explosion proof sensor includes potting and encasing the sensor in its own explosion proof case.

In a first embodiment, the conductors are insulated, and the contacts are of the insulation piercing type. In another embodiment, the conductors are bare, and the stationary contacts are resilient and are biased toward engagement with the conductors. A lock nut arrangement serves to lock the cable to the socket member.

Abstract: A system for protecting a cable connector, and especially an RJ-45 cable connector, from damage or abuse during use with a chassis receptacle. A cylindrical carrier housing for the connector contains a transverse septum having a shaped opening for receiving and positioning the connector within the housing. A radially-compressible chuck on the cable compresses to grip the cable. A boot on the cable and protrudes from the housing through an overriding bushing threadedly connected to the housing. The boot isolates the cable from flexural stresses. When the bushing is tightened onto the housing, the boot is urged toward the housing, radially compressing the chuck onto the cable. Longitudinal stresses on the cable are therefore isolated from the connector and are transferred instead to the housing. A mating chassis receptacle is receivable of the connector and has an annular groove on an axial face thereof for receiving and rotationally positioning the housing for insertion into the receptacle.

Abstract: An electrical outlet or plug includes a body, which encloses a connecting jack, which can be connected to a cable, and a grip element for clamping the cable. The body and grip element are provided with complementary features, which limit the axial unthreading movement of the latter in relation to the former and for preventing their disconnection once they have been connected. A locking nut is joined to the grip element axially, with the possibility of remaining joined to the said grip element, and through this, to the body when the nut is completely unscrewed and removed. Structure is also provided for preventing the unscrewing rotation of the nut once it has been screwed down.

Abstract: The invention is a housing assembly that is designed to be placed over the coupling area between two power/extension cords. The assembly includes a two-part central housing in which the two parts are joined together by a quick-release-type coupling that includes a gasket or "O"-ring. At each end of the housing are two threaded end caps. Located at least partially within each end cap is a compressible bushing. The bushings have a central thru-bore through which the power cord passes. As the end caps are tightened onto the housing, the housing contacts and compresses each of the bushings to create a leak-free sealing of the interior of the housing.

Abstract: A two-piece, all plastic connector for connecting a flexible conduit to an electrical fixture comprising a threaded connector cap having an extending wedging ring and a mating threaded connector body having a deflection ramp. The connector body is secured to an electrical fixture and the connector cap is loosely threadably engaged with the connector body. The conduit is inserted through an opening in the connector cap until it abuts the bottom of an annular cavity in the connector body. The cap is then tightly screwed onto the body such that the wedging ring is cammed, by the deflection ramp, into engagement with the conduit to securely grip the conduit. This arrangement provides a liquid-tight seal.

Abstract: The present arrangement includes a central housing member which has a hollow chamber therein and which has at least two apertures passing from the outside wall into the internal hollow chamber. The apertures are disposed, or positioned, so that their axes are at an angle of less than 180.degree. to each other and in a preferred embodiment are at right angles to each other. The walls of the apertures are formed to be connectable. In the preferred embodiment one of the aperture walls is threaded internally to accept an externally threaded cable connector piece while the other aperture wall is formed into an externally threaded protrusion thereby enabling an internally threaded cable connector piece to be threaded onto the externally threaded protrusion. The cable connector pieces are designed to be secured to a cable and thus the entire cable connector assembly is secured to a cable which cable is positioned to define a right angle (or other angle) path.

Abstract: The present arrangement includes a support member which is formed to: (1) have tines extending from one end; and (2) have a threaded section lying adjacent to the beginning of the tines. In addition the present arrangement in the preferred embodiment includes a rubberized cone shaped insert which has an aperture therethrough and which enables a great number of different sized cables to be clamped. Further in addition there is included a compression nut which is internally threaded in one section, which is shaped internally concave in another section (and which has an aperture therethrough), and which is threaded onto said support member. Such threading action causes the tines to be bent inward toward one another and simultaneously to pass through the aperture of the compression nut. The tines are serrated on their respective inner surfaces and as they are bent toward each other they come in contact with the rubberized insert and act to clamp thereon which in turn secures the support member to a cable jacket.

Abstract: A multi-wire data transmission cable for transmitting data signals over long distances between data devices. Presently, data devices are usually equipped with voltage interfaces for the connection of peripheral instruments. The length of data transmission lines connecting such devices is limited, due to line resistences. For transmission over long distances, signals must be converted prior to transmission and then must be reconverted after receipt of transmission. The present invention allows the connection of long transmission lines to data devices without the need of external signal converters or additional units normally required. The handle portion of the plug connection at either or both ends of the cable houses a circuit that incorporates a signal converter. No additional external units are required to connect data devices over long distances, since the converter is integrated into the cable.
