Coil bobbins are disclosed having flanged coil support portions provided with outboard terminal housings projecting beyond the flange rim and defining inwardly extending terminal-receiving cavities. The end walls of the housings are slotted to allow a wire to pass through the cavity in a circumferential direction relative to the winding axis in similar fashion to a turn of coiling. Bifurcated terminals pressed into the cavities in straddling relationship to the wire provide connections to the coil.A double bobbin has twin flanged coil support portions with bridging sections maintaining their physical separation. Terminal housings are provided on the bridging sections allowing wire to be first wound into a coil on one support portion, guided across the bridging section and passed through the cavity in a terminal housing, and then wound into a coil on the other support portion, all without interruption.

An electromagnetic deflection unit for a cathode ray tube, comprising has at least one support (4) with a flange (8) at its narrow end (5), which has a tangential groove into which merge radial grooves (14). Two sets of deflection coils (18, 19) are wound directly onto the support (4). The turns thereof traverse the radial grooves (14), the turns of at least one set of deflection coils (18) being bent into the tangential groove. The radial grooves (14) have longitudinally extending portions (16), which are filled by the turns traversing them. The bottom portion (20) of the tangential grooves lie on the surface of an oval cylinder. The deflection unit has a high sensitivity, large axial sliding tolerance and permits correction of various kinds of deflection errors.

An electrical apparatus, such as a solenoid assembly 10, and a method for making the solenoid assembly are disclosed. Various construction details which improve the integrity of the solenoid assembly against the leakage of fluids are disclosed. In one embodiment, the solenoid assembly has a first wall, such as a flange 14, which is substantially fused about the wall to a second wall, such as an encapsulating casing 18.

A transformer of small installed volume which affords, besides electrical separation, also an effective static protective shield between the power supply side and the user side, along with simple production and assembly. To accomplish this, a two-chamber transformer with a coil form for the primary winding and a coil form for the secondary winding, both plugged one behind the other onto the transformer core in the direction of the coil axes and a stamped metal foil frame as the shielding wall between the adjacent face flanges of the coil forms are used. The transformer is particularly well suited for application in equipment of the entertainment, communications and medical technologies.

Each end of an insulating tube which surrounds a transformer core projects beyond the electric circuits carried by the tube and is associated with an annular spacer member having two radially displaced bearing surfaces applied respectively against the core and the tube. An axial slit formed in the insulating tube is opened-out in order to insert a transformer core within the tube and then re-closed. A driving wheel is removably coupled to the tube in order to drive it in rotation during the winding operation.

An inductance element of the type that includes a coil bobbin having flanges at the ends thereof, a pair of pot cores engaging the bobbin, and a fastening member for fastening together the pot cores and bobbin. At least one of the bobbin flanges includes a joining part that extends outwardly from the bobbin flange and engages both the adjacent one of the pot cores and the fastening member to prevent relative rotation of the bobbin and adjacent pot core and fastening member. One of the bobbin flanges may include a stepped part having pins extending therefrom for making electrical connection to the inductance element. The stepped part is spaced from the bobbin flange, and connection wires may extend within the space.

The present invention provides a focussing solenoid for focussing an electron beam in a picture taking tube. This focussing solenoid comprises a sleeve which has a helical etching in which are housed the turns of a first layer of wire. For all the other layers of wire wound in a helix about the sleeve, the slope of the turns of the helix with respect to the sleeve is substantially the same and the turns of one layer are guided by the turns of the preceding layer. Connections connect the layers together so that all the layers have the same winding direction about said sleeve.

A coil form for supporting both symmetric and antisymmetric magnetic field correction coils includes a system or circumferential slots and axial grooves disposed at various depths in the form to achieve the desired winding pattern. A winding method for this coil form is provided in which tension in the winding conductor, preferably a superconductive material, is maintainable at all times during assembly, and increased upon immersion in cryogenic fluid. Accordingly, the coil form and winding method provide a means for constructing axisymmetric coils which are resistant to frictional motion and which may be placed in direct contact with cryogenic fluids.

A coil form for a transformer having air-cooled electric windings. Plug-in frames which can be adjusted in width and/or height are provided at the ends of the device. Profiled bars and additional supporting members, both of which can be of any desired length, are mounted between the frames at each corner thereof and are laterally spaced so as to space the coil windings wrapped therearound.
