Abstract: A connection terminal for connecting a conductor is formed as a direct plug-in terminal and includes a clamping spring arranged in a housing. The clamping spring includes a resilient clamping leg which can move into an open and locking position by pressing down an actuating device. The housing contains a conductor insertion channel for insertion of the conductor into a clamping point between the free end of the clamping leg and a busbar. The actuating device includes a pressing element and a pivoting element which interacts with the pressing element at least when the clamping point is being opened. At least one release device is provided for releasing the locking state of the clamping leg of the clamping spring. The release device is designed in such a way that the locking position can be released again by the action of the conductor on the release device when it is inserted, wherein the pivoting element acts on the pressing element and the pressing element acts on the clamping leg.

Abstract: A direct clamp terminal for connecting a conductor in the form of a flexible stranded conductor includes a housing with a chamber and an insertion conduit for inserting the conductor into the chamber. A bus bar or a clamping cage is provided in the housing and a clamping spring is located in the chamber and acts as a compression spring for securing the electrical conductor to the bus bar or the clamping cage in the area of a clamping point. The clamping spring has a clamping limb that can be pivoted about a pivoting axis and that can be shifted from a detent mode in which it is locked in a detent position into a clamping mode in which it is released from the detent mode and presses the electrical conductor against the bus bar or the clamping cage. The clamping limb can be released from the detent mode using two different shifting devices.

Abstract: A connector arrangement is provided for supplying electric power to a three-phase motor to produce motor operation in either a delta mode or a star mode, use being made of modular units that are removably mounted within a chamber contained in an outer frame that is secured to the motor housing. A power supply module arranged within the chamber includes a main receptacle containing a stack of terminal blocks having bus bars that transmit to the motor windings three-phase power that is supplied either by external power supply lines that extend into the chamber though openings contained in the side walls of the outer frame, or from an inverter arranged externally of the outer frame. Auxiliary receptacles are removably connected with the external surface of the main receptacle for monitoring the operating condition of the motor, or for controlling a motor operation, such as braking.

Abstract: A plug connector and a method of coding of same is characterized by first and second coding elements that are pre-mountable as a unit on at least one of a pair of plug connector components. The other plug connector component is configured so that when the connector components are initially connected together in an axial direction, one of the coding elements is connected with one of the components and the other coding element is connected with the other component. When the components are separated axially, the respective coding elements are separated so that each are retained on the component with which it was originally connected.

Abstract: A printed circuit board arrangement and method includes a planar generally-rectangular vertically-arranged printed circuit board having front and rear surfaces terminating in a peripheral edge, at least one of the front and rear surfaces having a conductive printed circuit thereon. The printed circuit board has a vertical side edge portion containing a recess, and arranged adjacent the recess is a fixed contact connected with a conductor portion of the printed circuit. A relatively narrow conductor housing arranged outside the peripheral edge of the printed circuit board is mounted in the recess with a movable contact carried by the housing in electrical engagement with the fixed contact. The connector housing is supported by a rear wall mounted on the rear surface of the printed circuit board, and by a resilient clip on the connector housing that engages the printed circuit board adjacent the recess.

A locking arrangement may be provided for locking together the connector components in the electrically engaged condition.

Abstract: A cable includes a cable sheath in which are embedded a plurality of insulated conductors at least two of which are helically twisted, the cable being provided with visible markings that indicate where one can electrically engage a selected one of the conductors by an insulation-piercing contact. The cable is formed by arranging a plurality of insulated conductors in a light-transmitting synthetic plastic sheath layer, two or more of the insulated conductors being helically twisted about a longitudinal axis, which cable is optically scanned to determine locations at which contiguous portions of the twisted insulated conductors are superposed orthogonally relative to a reference plane, whereupon markings are formed on the cable sheath layer at locations laterally spaced from the contiguous conductor portions, whereby a selected one of the twisted conductors may be engaged by an insulation-piercing contact.

Abstract: An electrical connector arrangement includes a socket having a central body portion supporting a plurality of female contacts, and a tubular outer portion extending in concentric spaced relation about the body portion to define a groove. A plug component having a cylindrical body portion including a plurality of male contacts includes a tubular end portion that extends axially within the groove to connect the male and female contacts, respectively. A fastening sleeve is rotatably mounted on the plug between the outer surface thereof and the socket outer portion, whereby external screw threads on the sleeve engage internal threads on the socket tubular portion, thereby to fasten together the plug and socket components. In order to reduce the assembly time, the number and length of the screw threads on one of the sleeve and socket components is less than the number and length of the screw threads of the other component.
