Abstract:
An electrical junction box has a first insulating polymeric portion and a second polymeric portion defining multiple electrically conductive circuits. The circuits are at least partially separated by the first insulating polymeric portion and at least some of the circuits electrically connect together wire harness connector portions. A further aspect of the present invention junction box causes a section of the first insulating polymeric portion to concurrently act as a segment of an outer protective cover for the junction box.

The size precision of a surface mountable electronic part is improved and a production thereof is simplified. The surface mountable electronic part is constructed such that a circuit substrate is housed in a shield case of which an end side is open, and the shield case is a resin case having a shield film. A connection pattern is formed on the inner surface of the case, with one end of the connection pattern being disposed so as to correspond to an external connection land of the circuit substrate, and with the other end of the connection pattern extending to the open end of the case.

An electronic device comprises a housing made of a polycarbonate resin, and a novel double-sided printed circuit board. The printed circuit board has one side embedded in the housing, and the other side exposed to the interior of the housing. A plurality of refractory electronic components are mounted onto one side of the printed circuit board and include a resistor and a capacitor. A plurality of lower refractory electronic components are mounted onto the other side of the housing and include a semiconductor integrated circuit, and a transformer. Preferably, an insulating layer is applied to cover the one side of the printed circuit board and the refractory electronic components. Also, a metal layer is applied to cover the insulating layer and the inner surface of the housing.
Abstract:
In a control device (11), the strip conductors (29) are applied to the interior wall (28) of the housing (15), consisting of plastic, with integrated plugs (16) with the aid of novel deposition processes. In this case the laser-assisted deposition process or the Ivonding.RTM. process can be used in a particularly advantageous manner. It is possible by means of these types of manufacture to dispose the plug connectors (24) in a simple manner in a through-bore (23) in the housing (15) and to connect them directly with the strip conductors (29) on the interior wall (28). Bonded connections (31) for connecting hybrid circuits (13), for example, can be attached in a simple manner at the other end of the strip conductors (29). Because of this, it is possible to automate the manufacturing process to a large degree and to make it inexpensive.
Abstract:
A structure for a terminal plug includes a thermoplastic resin base having a key boss and a plurality of protruding shafts formed integrally on a front side thereof. Terminal pins are formed on the plurality of protruding shafts by a chemical plating process. Connection patterns are disposed on the front side of the thermoplastic resin base and connected to said terminal pins, and circuit patterns are disposed on the back side of the thermoplastic resin base. A plurality of through-holes are formed in the thermoplastic resin base which electrically connect the connection patterns and the circuit patterns.
Abstract:
Using sheet battery material as a circuit board substrate eliminates the weight and bulk of batteries as a separate circuit component and also eliminates the weight and bulk of fiberglass substrate or flex substrate as printed circuit materials. Insets with wiring built in can give vertical wiring between two or more circuit layers and can support electronic components which have leads connecting wiring on more than one layer of a printed circuit. Connector clips inserted when the connector pins are polarized target connection to power and to ground components of one or more layers of sheet battery. Using these connections between battery substrate components of the structure allows a single power source as A-C or solar to recharge all battery substrate in the electronic component. The effect of application of these discoveries is to reduce the size and mass of the circuit and thus reduce the size and weight of electrronic devices from hearing aids and flash lights to portable computers, from video cameras to mini and portable television sets and radios.

A method of providing an electrical circuit wherein a carrier, which is a film of insulating plastic material with a circuit pattern thereon is supported in a mould and a moulding material is applied by the application of heat and pressure to provide a substrate so that the circuit is embedded in or within a three-dimensional surface of the moulded substrate.
Abstract:
A hybrid integrated circuit device comprises a metal substrate, a casing member and external leads. An insulating film is formed on the metal substrate, conductive paths are formed on the insulating film, circuit elements are connected to the conductive paths, and conductive pads are formed in the tip portions of the conductive paths. The casing member comprises a sealing portion surrounding the circuit elements and a connector portion projected from the bottom portion of the sealing portion and extending beyond an end of the metal substrate, and formed of insulating resin. Each of the external leads has one end connected to each of the conductive pads and supported by the side surface of the connector portion.
Abstract:
A PC board consisting of a conductive layer laid through an insulating layer on a metal plate surface is easily bendable to make any desirable shape. This permits any desired distance to be provided between the display element and the PC board. In addition, it is possible to form display element-fixing angles integrally with the PC board. As a result, the number of components required is decreased and production efficiency improved. Moreover, the metal plate of the PC board protects the display device from unnecessary radiation, external noises and/or static electricity.
Abstract:
Three Dimensional Circuit Modules For Thick-Film Circuits And The Like And Methods For Making Same are provided in which such circuits are printed in selected portions on both the internal and external walls of a hollow cylindrical substrate to remove the crossovers normally present in an equivalent planar circuit configuration. The circuit sections are disposed on the substrate such that common connections therebetween are effected by conductive clips straddling the end faces of the substrate in notches or declivities formed therein to receive the clips. Like declivities are utilized to both physically and electrically interconnect a plurality of substrates and/or external circuit components and the like. These substrates also comprise a housing for self-contained functional circuit modules of the foregoing type.
