Abstract: The invention relates to a connection arrangement having a rectilinear insulation-piercing and wire-retaining slit, and to a tool endpiece for providing connection between wires (2) and such arrangements. The insulation-piercing and wire-retaining slit extends longitudinally along a profile-shaped portion (31, 32, 33) of a conductive part (3) having a U-shaped cross-section with the free ends of the U being folded towards each other and leaving a space therebetween corresponding to the width of the slit, said profile-shaped portion being intended to serve as a guide for the endpiece of the connection tool (6). The endpiece includes a core (60) whose shape is complementary to the shape of the cavity in the profile-shaped portion and which slides therealong. The endpiece slides parallel on either side of each of the folds (31) delimiting the slit in the profile-shaped portion, and it enters the housing via a hole (51) whose shape is complementary thereto, which hole, serves to guide the tool.

Abstract: The socket is foreseen for fastening and connecting an electronic component with lined-up conducting pins, whereby the free end of the pins is parallel to the main plane of the component, as it is the case for the SMD components. The socket comprises a carrier of insulating material and contact elements maintained in the carrier and positioned each with its first flexible end in the face of a pin for applying a determined contact pressure on that pin when the component is mounted in the socket. The second end of the contact element can be soldered to a conductor in a circuit. The socket comprises further a comb of insulating material with teeth gliding in a guidance of the carrier.

Abstract: A ground contactor couples to the space between the pipe fitting used in the electrical supply conduit. The contactor consists of a knife-edge contacting surface having a screw thread adjustment located at the surface. The screw thread is a pointed screw thread which is adjustable without removing the contact surface for the space. The contact surface is clamped by a U-shaped clamp and tightened securely in the pipe fitting space. Angular contact surfaces are provided at the points of threaded adjustment between the clamp and the contactor so that forces are created for adjusting the clamp relative to the contact surfaces to permit the device to be used on conduits of different diameters. The contactor thus shaped and configured permits permanent electrical ground contact to be achieved and also permits serviceability of the electrical conductivity of the conduit connection arrangement without the necessity to move or otherwise disturb the ground contactor installation.

Abstract: The present invention provides a modular electrical power block assembly including a plurality of ports for receiving individual modular circuits. The power block assembly includes seven separate electrical conductors, three of which are hot, two of which are neutral and two of which are ground, for providing three separate and independent circuits. The hot wire of one of the circuits is advantageously separated from the hot wires of the remaining two circuits by two grounds and two neutrals and one circuit may be shielded to prevent penetration of electro-magnetic interference from the other circuits. Individual circuit modules are adapted to be received within individual ports of the power block for selectively completing one or more of the three independent circuits provided by the power block assembly. The contacts extending from the individual circuit modules are arranged to engage only preselected wires within the power block assembly for completing a predetermined circuit.

Abstract: A bistable zero insertion force connector assembly including one or more conductive contact members. Each conductive contact member includes mating ends or contact arms having contact surfaces and a resilient central segment. Variable engagement means cooperates with each conductive contact member to displace the member from a first stable state to a second stable state and vice versa, with minimal force the member being maintained in the first or second stable states by means of stresses induced in the resilient central segment. In the first stable state the contact surfaces of the mating ends or contact arms are disposed in mating proximity to the contact surfaces of the device to be electrically connected therewith with zero force/zero contact while in the second stable state there is secured engagement between the respective contact surfaces. Wiping contact between the respective contact surfaces during transition between the first and second stable states enhance reliability of the electrical connection.

Abstract: An electrical connector assembly permitting interconnection of signal and ground conductors in a shielded flat cable to a standard connector member having a different signal ground configuration is disclosed. An adapter member having an insulative housing base and cover can be secured to the connector member. A plurality of signal terminals can be disposed in the base member to form insulation displacement terminations to the signal conductors. Separate ground shields surrounding associated pairs of conductors can be commoned using a ground terminal having a single transverse bus strip which is deployed over the cable in the insulative base. The assembled adapter base is received within an outer conductive shell which interconnects an outer cable shield to the outer conductive shell of the standard electrical connector to form a continuous shield.

Abstract: The coder device prevents plugs being assembled to a counter-plug device having a different coding. The coder device is formed by tongue-like projections on a plug and by corresponding chamber-like recesses on the counter-plug device. The projections are provided with a theoretical breakage point and can be broken off. The broken off projections can be inserted into the associated recess of the housing of the counter-plug device. By breaking off projections in different combinations, it is possible to individualize the original universal coder device.

Abstract: An electrical connector for connection to plural contacts mounted on a printed circuit board, other support or the like, including plural electrical contacts for engaging and electrically connecting with corresponding ones of such plural contacts, a support structure for supporting the electrical contacts, a resilient latch mechanism for maintaining the electrical connector in position with respect to such plural contacts and such printed circuit board and independently of such plural contacts, a keying mechanism to assure correct contact to contact installation and an anti-rotation mechanism cooperative with such printed circuit board to prevent rotation of the electrical connector relative thereto during installation onto such plural contacts. In a preferred embodiment the plural contacts are connected, e.g. by soldering, to the printed circuit board or to circuits thereon or associated therewith, and the anti-rotation mechanism helps to prevent applying torsion forces to such connections.

Abstract: A centering and chucking system for fixing an interchangeable element to a carrier body. The carrier body is provided with guide elements whose guide surfaces are arranged along a coordinate system through the center of which extends the reference axis, e.g. the axis of a spindle. Due to the arrangement of two centering means along one axis of the coordinate system and of at least another centering means along the other axis, the reference axes of both parts are not displaced relative to each other by changes of temperature. Although the centering means are provided outside the reference axis, the system in said reference axis is determined by them.

Abstract: A method and an apparatus for connecting a plurality of electrical cable conductors to a corresponding plurality of conductors on a printed wiring board is provided. A section of the insulation at the termination end is displaced away from the adjacent section of insulation, thereby exposing bare conductors between the two insulated sections. The prepared termination end of the cable is then attached to a wire retaining device which guides the exposed conductors horizontally and vertically into physical contact with the printed wiring board conductors while isolating the conductors from each other. The retaining device is firmly clamped to the printed wiring board, thereby squeezing the ribbon cable conductors between the printed wiring board and the retaining device to provide an excellent electrical contact between the respective cable and printed circuit board conductors.

Abstract: An electrical connector achieves improvements in connecting a patient plate to an electrosurgical generator. The connector is preferably of the lever operated type, and electrical contacts are connected on the lever and connected within a passageway internally in a housing of the connector. A tongue portion of the patient plate is inserted in the passageway. Upon closure of the lever, the contacts on the lever extend into the passageway above the lower contacts to mechanically contact and retain the tongue portion between the contacts and to electrically contact the tongue portion by which to conduct current to the patient plate. A recess is formed in the lower marginal area of the passageway and a retaining structure on the lever member extends into the passageway to deform the tongue portion into the indention.

Abstract: A lever pivotally mounted on a forward brace of a removable control unit abuts a pin on the cabinet for limiting direct insertion of the unit to a depth insufficient to effect electrical engagement of plug-in connectors of the unit with bus bars in a motor control cabinet, such engagement requiring subsequent pivotal movement of the lever which automatically latches the unit in the cabinet. A compound movement of the lever is required to release the latch and separate the plug-in connectors from the bus bar. A detent structure maintains the lever in a first position for inserting the control unit into the cabinet and padlocking provisions are provided to insure the lever remain in that position when desired, thereby blocking full insertion of the control unit into the cabinet.

Abstract: A retaining plate (30) is provided to insure that leads (4) secured in a protective carrier (2) are maintained in electrical engagement with conductive areas of a substrate (18). The configuration of the retaining plate (30) also insures that as the retaining plate (30) is installed onto posts (12) without exerting harmful stresses to the substrate (18). Projections (48) and openings (40) cooperate with recesses (54) and posts (12) respectively, to provide a failsafe manner to provide the contact pressure required without damaging any part of the socket (10), protective handler (2), or retaining plate (30).
