Abstract: For a unilaterally contacting contact spring for electric connectors, it is proposed to influence the contact force of the spring limb by means of an adjusting spring which acts upon the spring limb. As a result, a high contact pressure is already achieved upon slight deflection of the spring limb and, upon maximum deflection, the characteristic curve of the spring presents a flatter shape so that the contact force does not assume excessively high values.

Abstract: For a switch plug with contact springs arranged in contact chambers of an insulating body, wherein at least two adjacent contact springs are connected by means of a jumper when no mating plug is plugged in, it is proposed, with a view to clearing the short circuit upon introduction of the blade contacts of a mating plug, to provide an actuating component made of plastic material in the entry zone of the blade contracts which acts upon a spring elastic jumper in such a way that the connection between the contact springs is broken.

Abstract: For a coaxial angular connector with at least two coaxial contacts for installation on a printed circuit board, with a housing block assembled from two subshells, in the interior of which the neutral wires of the coaxial contacts are taken from a plug connection side to a terminal side on the printed circuit board, it is proposed that two mutually overlapping partitions or shielding walls be provided between the neutral wires for their mutual shielding. Due to the overlapping of the partitions, the joint gap of the two half shells between the neutral wires is constructed as a labyrinth impermeable to high frequency radiation.

Abstract: A shielded printed circuit board plug-in connection and particularly a multipole socket plug-in connection includes a mating connector having a basic body provided with a conducting coating all around with the exception of the plug-in region and the region where the contact element ends emerge. The contact element ends facing the printed circuit board are covered with metallized caps and provided with conducting, elastic seals between the contacting areas of the caps and the printed circuit board or the basic body.

Abstract: Apparatus for operating needles of a textile machine includes magnetically operated control flaps for operating the needles, and magnetic controls operable to actuate the control flaps. The control flaps include a flap structure and an armature disposed on the flap structure, the magnetic controls being operable to magnetically actuate the armature to thereby effect movement of the flap structure, whereby the movement of the flap structure actuates the needles.

Abstract: For an electrical plug and socket connection with housing halves that can be locked together, for which a sleeve, which can be shifted in the longitudinal direction of the housing halves, is provided for cancelling the locking, it is proposed that the locking elements be constructed as latches, which grip behind the locking shoulder at the one half of the housing in order to lock the two halves of the housing together. For this purpose, the latches are provided with an inclined surface, which is acted upon by an edge of the sleeve to unlock the connection. When tension is applied to the sleeve in a direction opposite to the plug-in direction, the edge of the sleeve presses the latches out of the locking position.

Abstract: For an electrical connector for connecting insulated electrical conductors, preferably an electrical plug and socket connector, with contact elements disposed in chambers of a carrying base with cutting and insulation displacement connections for connection to the conductor, the conductors being introduced into the connector in the axial direction, relative to the contact elements, it is proposed that the conductors be pressed by means of a conductor guiding element, which is constructed as a pressure part, into the cutting and insulation displacement connections. At the same time, the conductors are pushed through a guiding borehole, in which they are deflected in such a manner, that they are guided obliquely through a recess in the conductor guiding element. When the carrying base and the conductor guiding element are joined together, the cutting and insulation displacement connections dip into these recesses and, in so doing, are connected with the conductors.

Abstract: A polarized, reversible magnet with an essentially U-shaped yoke includes an upper coil former flange constructed like a frame and which fronts on yoke legs provided with tab-like integral moldings which in turn engage recesses of the upper coil former flange. Permanent magnets and pole pieces are inserted from above through appropriate openings of the upper coil former flange into the magnetic system.

Abstract: An electrical plug and socket connector with a U-shaped locking hoop has cylindrical rollers provided at the side parts and the overlapping parts of the locking hoop. The rollers are provided with a central slot and an axle and are snapped into the side parts. The attachment of the locking hoop to one plug and socket connector half is such that the locking hoop can be snapped onto the bearing pins of the plug and socket connector half.

Abstract: A plug connector with bent contact posts for insertion into printed circuit board holes includes a comb-shaped supplemental part having crosspieces with bearing shoulders for the contact posts disposed between the contact posts. The contact posts are mutually supported by way of the crosspieces so that a simple insertion tool, acting on the upper side of the upper row of posts, may be used for insertion of the plug connector.

Abstract: For a vending machine for dispensing parallelepiped products, which are arranged in horizontal product stacks, a dispensing device is provided, which separates the first product package to be dispensed by tipping the package away from the product stack, with the remaining product stack being held in place. It is furthermore provided that the product package falls onto an inclined plane when tipped, from which it slides down under its own weight and reaches the dispensing opening of the vending machine. It is further provided that the dispensing device follows the product stack as the products are dispensed, or that the product stack be made so that it can move towards the dispensing device. The dispensing device is arranged on horizontal guide rails and several dispensing devices can be provided within one product row.

Abstract: A pin-shaped contact element that can be fixed in printed circuit board boreholes, preferably in metallized printed circuit board boreholes, has a fastening section with two parallel side parts that can move elastically towards one another and a gradually tapering insertion region, the elasticity of the insertion region being increased by providing in the insertion region an opening which runs transversely to the connecting web of the side parts and interrupts this connecting web in the transition or connecting region to the lower end of the pin.

Abstract: The invention refers to an apparatus for inserting a flat cable into a housing, which ensures safeguarding the cable or the cable connections on the inside of the housing against tensile stress. The apparatus is to a large extent adapted to the measurements of the flat cable (width/thickness) and also offers sufficient protection in preventing foreign material from entering into the inside of the housing.For this purpose, the housing is provided with a frame-shaped mounting part (1, 102) which has posts (14, 106) arranged on opposite sides. In the bottom area of the mounting part there is provided a cable passage (23, 104) facing towards the inside space of the housing, and in the mounting part there is provided a groove (22, 103) with rim-side shoulders (10, 105) for an insertable, elastic seal (2, 110). The seal is provided with a passage opening (28, 122) corresponding to the shape of the cross-section of the flat cable (9, 109).
