Abstract: An assembly is disclosed and comprises a pair of connectors, each including a body which securely receives in electrically-conducting relation the end of a welding cable and a sleeve which, in use, forms a grip for the body and receives same in a manner which provides access to the receiver for the cable end at one end and provides access to the body at the other end. The pair has: an initial position wherein they define a longitudinal axis and wherein the sleeves are disposed other end-to-other end, aligned with the axis; a primary lock, which locks the connectors against longitudinal movement relative to one another upon rotation of the connectors relative to one another about the axis from the initial position and permits electrical conduction between the bodies when the connectors are so locked; and a secondary lock which selectively arrests relative rotation of the connectors about the axis.

Abstract: A plug connection for jaw stump models for the releasable connection of tooth crown segments or jaw segments to a model base, which includes a plug pin (1) which can be connected in snap-lock fashion with a sleeve (12). A non-rotationally symmetric design of a rotational locking section (4), and a cross pin (7) arranged perpendicular to the plug pin axis, prevent rotary movement of the plug pin (1) in the sleeve. Disposed at the end of the plug pin (1) facing the sleeve is a spring element (8), which is provided with a circumferential annular groove (11) for a snap-locking connection with the sleeve. The spring element (8) comprises two spring tongues (10) separated by a continuous longitudinal slot (9). The sleeve provided for receiving the plug pin (1) comprises a projection projecting into the inner chamber for the snap-lock connection of the plug pin (1) with the sleeve as well as a sleeve opening region matching the rotational locking section (4) of the plug pin (1).

Abstract: Disclosed is a male and female power connector assembly in which the male contact is provided with a biased plunger which prevents insertion of a finger into contact with an electrically live component housed within the male connector. The female connector also includes a housing which prevents or induces the likelihood of an object coming into contact with an electrically live component on the female connector. The male and female power connector assembly of the present invention also includes a unique alignment and locking mechanism including a slot having a recessed area on the male for engagement with a tab in the female connector. Also a front flange in the male connector can have at least one slot for engagement with a pin in a pin connector in the female connector.

Abstract: An electric storage battery connector assembly, including a male connector, which includes an elongate, generally cylindrical, electrically-conductive post having a fixed end for being attached to an electrical cable and a free end. A female connector electrically communicates with a terminal of the battery. The female connector is formed of an electrically-conductive material and has a recess therein for receiving therein the post of the male connector. A cam is integrally-formed on the free end of the post of the male connector, and a cam follower is carried in the recess of the female connector for cooperating with the cam on the post of the male connector for relative rotational movement between the unlocked position where the post may be inserted into or removed from the recess in the female connector, and the locked position where the post is locked into the recess of the female connector against removal therefrom.

Abstract: A female power contact which is energized only upon insertion of a male plug. The contact includes a plunger which is biased toward a position which blocks accidental finger insertion into the contact. The plunger also contains sharp points on its outer edge to further prevent accidental finger insertion into the contact. However, insertion of the male plug into the female power contact, against the spring bias, causes the plunger to depress the spring in order to produce an electrical connection between the male plug and female contact.

Abstract: A first terminal and a second terminal are provided, in which a winding terminal of a coil is connected to the first terminal and one end of the second terminal is positioned to overlap one end of the first terminal. One end of each terminal is connected by a soldered portion 12. One end of the first terminal is designed to serve as an engaging projection which is bent at a generally right angle to the longitudinal direction thereof. The engaging projection engages an engaging opening formed on one end of the second terminal. A constricted part is formed near the engaging opening to reduce heat escape. Because the first terminal and the second terminal are firmly secured to each other, a soldered portion is not affected by stress resulting from differences in the coefficients of thermal expansion of the terminals, the solder and the resin due to a change in application temperature and therefore, the reliability of the soldered connection is improved.

Abstract: An electrical cable connector for releasably electrically connecting ends of an electrical cable comprises a female element coupled to one end of the electrical cable, and a male element coupled to another end of the electrical cable. The male element is releasably connectable with the female element. A locking groove is disposed on one of the female element and the male element. A screw is removably disposed on another one of the female element and the male element. A cam surface is located on the screw and is engagable with the locking groove such that the cam surface cams along the locking groove responsive to rotation of the female element relative to the male element to releasably connect the female element with the male element thereby electrically connecting the ends of the electrical cable. A slot is operatively associated with the locking groove.

Abstract: An electrical wiring material having a cooling function is characterized by a long hollow conductive body within which operating fluid is internally confined. An electrical connection piece is provided at the end portions of the conductive body, or other portions thereof. When used to wire electronic apparatuses, resulting heat is radiated due to evaporation and condensation of the operating fluid within the hollow conductive body. The wiring material may be used to wind a transformer, particularly the low voltage side, to provide a self cooling transformer.

Abstract: Hermaphroditic electrical terminals positioned within hermaphroditic insulative housings are suitable for electrical power distribution. Each terminal has an inclined contact arm opposed to a generally flat contact arm. Both contact arms are longitudinally coined. Each generally flat contact arm is sandwiched between the two arms of the other terminal when the two terminals are mated. The convex coined surfaces on the inclined arms engage concave coined surfaces on the generally flat contact of the other terminal to maintain the line contact between convex coined surfaces on the generally flat contact arms in static equilibrium.

Abstract: A biomedical "tab" type of electrode suited for use with male and female connectors of the type that are adapted to snap together is provided. The female connector is located at one end of a lead wire. A male snap connector is secured to the lead wire by means of a flexible tether. The electrode includes an extension or tab having an opening therein. The tether is mounted on the lead wire and is preferably adapted to slide along its length. During use, the male snap connector can be moved into proximity of the female connector and aligned with it on opposite sides of the tab portion of the electrode and then brought into contact and connected to each other through the opening in the tab to establish both a mechanical and an electrical connection with the tab of the electrode.

Abstract: For reliable heavy duty repeatable connection of heavy duty electric power lines of a portable, mobile or temporary nature, involving frequent changes such as extension or relocation, the connector of this invention couples readily in a twist action which locks large area contact surfaces together uniformly and positively to eliminate the risk of accidental uncoupling, degration over time with repeated usage, and general unreliability experienced in non-locking type connectors of known art in this class of service. An uncomplicated rugged configuration, machined from brass, provides mating cone-shaped contact surfaces. A specially located steel pin incorporated into the socket member engages a thread groove in the plug member including a lead-in ledge to clear the pin and guide it into the groove during twist-locking.
