Abstract
An electronic device includes: a spacing tube including a first conductor of a tubular shape with both end faces forming electrical connection, and a second conductor provided inside the first conductor to be electrically spaced from the first conductor, the second conductor including recess to be engaged with screws in both ends thereof; and a first wiring board and a second wiring board which are attached to opposite ends of the spacing tube by the screws fastened to the recess, respectively, and electrically coupled with each other through the first conductor and the second conductor.
Claims19
An electronic device comprising:
- a spacing tube including a first conductor of a tubular shape with both end faces forming electrical connection, and a second conductor provided inside the first conductor to be electrically spaced from the first conductor, the second conductor including recess to be engaged with screws in both ends thereof;
- and
- a first wiring board and a second wiring board which are attached to opposite ends of the spacing tube by the screws fastened to the recess, respectively, and electrically coupled with each other through the first conductor and the second conductor.
An electronic device comprising:
- a first spacing tube including first conductor of a tubular shape with both end faces forming electrical connection, and a second conductor provided inside the first conductor to be electrically separated from the first conductor and including recess to be engaged with screws in both ends thereof;
- a second spacing tube including a third conductor of a tubular shape with both end faces forming electrical connection, and a fourth conductor provided inside the third conductor to be electrically separated from the third conductor and including recess to be engaged with screws in both ends thereof, the fourth conductor being fastened to the second conductor of the first spacing tube;
- a first wiring board attached to one end of the first spacing tube by the screw, and including wiring patterns on both surfaces thereof;
- a second wiring board attached to one end of the second spacing tube by the screw, and including wiring patterns on both surfaces thereof;
- and
- a third wiring board sandwiched between the first spacing tube and the second spacing tube, and including wiring patterns on both surfaces thereof,
- wherein a wiring pattern on one surface of the first wiring board and a wiring pattern of one surface of the third wiring board are electrically coupled with each other through the first conductor, a wiring pattern on one surface of the second wiring board and a wiring pattern on the other surface of the third wiring board are electrically coupled with each other through the third conductor, and a wiring pattern on the other surface of the first wiring board and a wiring pattern on the other surface of the second wiring board are electrically coupled with each other through the second conductor and the fourth conductor.
A spacing tube comprising:
- a first conductor of a tubular shape with both end faces forming electrical connection;
- and
- a second conductor provided inside the first conductor to be electrically separated from the first conductor, and including recess to be engaged with screws in both ends thereof.
