摘要： 1367989 Capacitors AEROVOX CORP 12 June 1972 [17 June 1971] 27293/72 Heading H1M A multi-sectioned wound capacitor comprises a strip 11 of dielectric material bearing a metallized electrode layer 12 on one surface except for margin 15, a second dielectric layer 16 and, e.g. as shown, two counter-electrodes constituted by metal foils 17, 17 1 longitudinally separated and provided with tab leads 21, 22. Connection to electrode 12 is by a metal coating on the appropriate end face of the roll and a lead may be soldered to this to extend from the opposite end face from tabs 21, 22 (Fig. 3, not shown) or brought through the centre of the roll to extend from the same end face (Fig. 4, not shown). The dielectric layers are preferably of the same material, e.g. paper, polypropylene, fibreglass. Layer 12 may be vapour deposited or chemically deposited aluminium and foils 17, 17 1 may also be aluminium.

摘要： Wound film capacitor and method of making wherein at least two layers of shrinkable thermoplastic dielectric are sandwiched between two layers of metallized or, preferably, foil, electrodes. A pair of lead wires are then positioned against the outer surfaces of the foils and rotated together in the manner of mandrels to wind the film and foil layers into a capacitor body. Flat, or otherwise deformed portions formed on a short portion of one end of each lead wire which is outside of the capacitor during winding are then drawn into the center of the capacitor by pulling on the other end of the wires. The capacitor body is then heated to shrink the dielectric and thereby cause the leads to be held in extremely firm engagement with the foil layers. Since the foils encircle at least 270 DEG of the periphery of the lead wires, a very firm, low resistance, pressure bond is made which renders the capacitor able to withstand substantial amounts of heat applied during a soldering operation. The elimination of mandrel holes allows the capacitor to be extremely compact and usable for many applications without the addition of additional thicknesses of sealing materials.

摘要： 1,100,074. Welding by pressure. SIEMENS A.G. 13 June, 1966 [14 June, 1965], No. 26207/66. Heading B3R. [Also in Division H1] In the production of a coiled or layer type capacitor having alternate tin foil & dielectric layers, a terminal element of copper coated with silver is pressed on to the tin foil by means of two electrodes and current passed to cause heating and welding of the terminal element to the tin foil. The copper terminal may be silver coated only in the area to be welded to the tin foil. Welding can be effected even if the tin foil is varnish coated on both sides; to prevent damage to the varnish layer on the side remote from the terminal welding may be carried out with the tin foil supported on a thermally conductive e.g. a metal, supporting body.

摘要： 863,341. Mounting terminals; capacitor terminals. SIEMENS & HALSKE A.G. July 19, 1957 [July 24, 1956], No. 23010/57. Classes 37 and 38 (1). Terminals are formed at the ends of a rolltype capacitor by reversely bending lead-wires 4, 5 projecting from the ends of the capacitor body and locating the ends 8, 9 in an axial bore 6 in the body separated by an insulating rod 7, the material of the body being such that upon heat treatment it contracts thereby gripping the ends 8, 9. Instead of providing the rod 7, the free ends of the wires may be separately insulated, Fig. 2 (not shown), and the loops 10, 11 formed by bending the lead-wires may be twisted and soldered. Fig. 3 shows another construction wherein lead-wires in the form of strips 30, 31 are joined to connecting wires 36, 37 at 38, 39 and the joined ends bent back and located in spaces between unmetallized turns adjacent the outer surface of the capacitor body, subsequent heat treatment of the body causing a space 40 to close up and the material around the joints 38, 39 to grip them.

摘要： 848,440. Capacitors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 3, 1959 [March 10, 1958], No. 7560/58. Class 37 In a rolled foil electric capacitor the electrode leads are formed of flexible metal foil strips 5, 7 separated by thin insulating layers 6, having their edges superposed, the insulating material being of greater width than the conducting strips.
