Abstract:
A chip fuse includes a substrate, a fuse element extending on the substrate, and first and second wire leads coupled to the fuse element. Contact pads may extend over portions of the rase element and establish electrical connection to the first and second leads. A conductive medium such as solder encircles the substrate to securely form a mechanical and electrical connection to the leads.

Abstract:
In a printed circuit board (1) and electronic elements (4, 8) for mounting in that printed circuit board, the electronic elements (4, 8) have surfaces allowing electrical connection with conducting layers of the printed circuit of the board. The printed circuit board (1) has at least one hole (5, 9), which is in principle perpendicular to the surface of the printed circuit board (1), and which ends at the conducting layers (2, 3) of the printed circuit of the board (1). In the hole (5, 9) of the board (1) at least one electronic element (4, 8) is mounted, having, at its terminals, surfaces allowing electrical connection with the conducting layers (2, 3) of the printed circuit of the board (1) through a joining substance, which creates an electrical connection of the electronic element and the printed circuit of the board (1).
Abstract:
A monolithic inductor (10) comprises an elongated substrate having opposite distal ends (14 and 16), each end having an end cap extending from the opposite ends to support the substrate (12) in spaced relation from a PC board, the end caps being formed with non-mounting areas and a deflection area for preventing the substrate resting on the non-mounting area, a substantially steep side wall (16) on the substrate side of the end cap (14) at the non-mounting area, and an inclined ramp extending up to a top of the end cap on the substrate side substantially opposite the non-mounting area, an electrically conductive soldering band (30) extending partially around each end cap, each soldering band having a gap (34) at the non-mounting area for thereby reducing parasitic conduction in the band (30), and an electrically conductive layer formed on the substrate in a helical path extending between the opposite ends and in electrical contact with the conductive soldering bands (30) at the ramps (120).
Abstract:
A surface mountable miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope (20) wherein a filament (22) is contained in contact with metal members (26) and (36) having glass-to-metal seals with the glass envelope (20). A substantial portion of the outer surface of the glass envelope (20) is coated with a light reflective metal coating (50), with a non-coated elongated window (52) transparent to light being left on the surface. The metal members (26) and (36) extend axially to the outside from the envelope and, when mounted to a circuit board provide electric contact for the lamp. At least one of the end members includes a unique surface feature, such as a flat portion (54) of an otherwise cylindrical surface, which is directionally coupled relative to the window (52) of the glass envelope (20) and which acts as a key or indexing surface for mounting the lamp assembly to the receiving surface (circuit board) with the window (52) disposed in the desired direction.
Abstract:
A molded electric part which has no lead wire and is reduced in size and weigth. The electric part is molded with resin to effectively prevent deterioration. A large batch of such parts are produced by injection molding using a multiple-cavity mold and thus they have a uniform size and good electrical properties. The molded film capacitor (1) is provided with a film capacitor element (2) and a container (3) formed of a synthetic resin having a high insulating property. The element (2) is placed in a recess (7) formed at the center of the container (3) and electrodes (2a) formed on both side faces of the element (2) are electrically connected to a film-like conductive pattern (4) formed by plating a metal by means of solder (5). Part of the pattern (4) is formed on the bottom of the container (3) as a film-like external connection terminal (8). The element (2) is airtightly molded with a sealing resin (6) so that no moisture can intrude into the recess (7).
Abstract:
A female electrical socket for receiving an electrical pin and for connection to a PCB is provided, the socket comprising a body defining an enclosure, the body comprising a first end and a second end each having an opening, wherein the opening of the first end or second end is configured to receive a male electrical pin to form a connection with the female socket, wherein the body has a central longitudinal axis, the socket further comprising a plurality of contact fingers on the body, wherein a first end of each of the fingers is attached to the body and a second end of each of the fingers is radially directed inwards relative to the first end towards the central longitudinal axis whereby in use the fingers provide a retention force to engage with the electrical pin, further comprising at least one wing extending outwardly from the first end of the body, the wing for connecting the socket to a printed circuit board and also for being picked and retained either by a suction or mechanical gripper. A corresponding method of manufacturing the socket is also provided.
