Description

  Embodiments described herein relate generally to an electric device formed with at least a pair of circuit boards and a winding component, and an electric apparatus including the electric device.

  Conventionally, in an electric device, a plurality of circuit boards are combined in order to reduce the size of a circuit board or to share a circuit unit. That is, when a plurality of circuit boards are combined three-dimensionally, the width dimension of the circuit board can be suppressed, and the size can be reduced. In addition, it is possible to manufacture various types of circuit board structures by configuring a circuit board for each circuit unit and making the combination of the circuit units variable, and there is a merit in terms of cost because the circuit units can be shared. .

  The plurality of circuit boards are mounted with divided circuit components, for example, arranged in a case or the like so as to face each other (see, for example, Patent Document 1). Here, each circuit board is fixed to a case or the like, and the circuit boards are connected by connectors or jumper wires attached to the circuit boards. If a connector or jumper wire is used, the number of parts increases correspondingly, and the part cost cannot be ignored.

  In addition, a discharge lamp lighting device has been proposed in which two circuit boards are combined so as to intersect each other and their connection patterns are electrically connected by solder (see Patent Document 2). That is, soldering is performed between the connection patterns of the first and second circuit boards in a state where the connection pieces of the second circuit board are inserted through the insertion holes of the first circuit board and penetrated.

  If each circuit board is provided with a connector for electrical connection between circuit boards, the number of parts increases and the cost increases, and the mounting space for the connector is required, and the circuit board is enlarged accordingly. Have Further, there is a disadvantage that a support structure for supporting each circuit board on a case or the like is required.

  Further, when two circuit boards are combined so as to intersect with each other, there is a problem that a three-dimensional occupied space by both circuit boards becomes large, and an envelope such as a case becomes large.

The pair of attachment portions are provided on both sides in the axial direction around which the winding of the main body is wound, and are attached so that the pair of circuit boards face each other. The pair of connection pins are fixed to the respective attachment portions so as to penetrate the pair of attachment portions and protrude outward from the respective attachment portions. The pair of connection pins electrically connect both ends of the winding wound around the main body, and are electrically connected to the electronic component on the circuit board.

  According to the electric device of the embodiment of the present invention, the winding component is mounted such that the pair of mounting portions are attached so that the pair of circuit boards face each other, and the pair of connection pins are wound around the main body portion. Since the wires are connected and electrically connected to the electronic components mounted on the circuit boards, electrical connection means such as connectors and jumper wires for connecting the pair of circuit boards can be omitted, and the pair of circuit boards It is not necessary to individually support the device in a case or an envelope that accommodates the electric device.

It can be easily accommodated and disposed in the apparatus main body 28 (resin case 31) having a narrow accommodation space such as a mini-krypton bulb. Further, in the electric device 1, one of the pair of circuit boards 2 and 3 is firmly attached to the resin case 31, and the support structure to the other resin case 31 can be simplified, so that the LED lamp 26 is formed at a low cost. It has the effect that it is possible.
