  • Patent number: 4934048
    Abstract: A surface mountable electronic device and method of making same wherein a discrete electronic device is encapsulated in a body of electrical insulating material having opposite ends and a mounting surface extending between the ends, and an electrode is provided on each end. Each electrode includes a portion on the end of the body in electrical contact with the corresponding lead of the discrete electronic device and a contact portion extending along the mounting surface for making electrical connection to a circuit portion defined on a surface to which the device is mountable. The discrete electronic device is manufactured, prior to encapsulation, by known techniques. Preferably the body is a rectangular solid with each of the four sides having electrode contact portions thereon to serve as one of four possible mounting surfaces each with substantial mechanical stability.

  • Patent number: 4914804
    Abstract: A method of making a surface mountable electronic device comprising the steps of providing a discrete electronic device comprising a body and a pair of spaced apart leads each of substantially circular cross-section and extending axially outwardly from the body in generally opposite directions, shaping each of the leads to provide a plate-like section in each of the leads at a location axially outwardly from the body, encapsulating the device body in electrical insulating material in a manner shaping the material to provide a body having first and second spaced apart ends and a mounting surface extending between the ends, the plate-like sections of the leads extending from the ends, and shaping each of the plate-like sections of the leads to have a contact portion extending along the mounting surface for making electrical connection to a circuit having a portion defined on a surface to which the device is mountable.

  • Patent number: 4757610
    Abstract: Surface mount networks and methods of making. One form of a network is a single in-line network. According to one method all components are mounted within a bar stock of generally rectangular cross section, the components have end caps disposed over a cylindrical body portion, which body portion is received within grooves on the bar stock material, and the end caps extending to the sides of the bar stock. A portion each of the end caps lies in a plane to one side of the bar stock so that the network can be mounted on the conductive traces of a printed circuit board. The single in-line network may also be molded to its final configuration. In another form two in-line networks are provided with a bus between adjacent end caps, a portion of the cylindrical wall surface of the end caps lying in a common plane on the periphery of the network and being adapted to be surface mounted onto the conductive traces of a printed circuit board.

  • Patent number: 4331946
    Abstract: The invention relates to a method of fastening electrical wire leads to each end of a ferromagnetic sleeve or core form in a manner whereby significantly greater bonding strength is provided between the leads and the core as compared to prior art methods. The core and wire leads are placed in a molding cavity into which molding material is injected so as to affirmatively fill the clearance between the lead ends and the core thereby resulting in a highly effective cementing of one to the other. The core body is hollow so that the molding material passes through each end to completely fill the central portion of the core. In this manner the central bore through the core body provides effective gating to the injected molding material. The ferromagnetic coil article so formed includes a molded flange on each of its ends which extend radially outward from the outer surface of the core body associated therewith.
