Abstract
A power supply terminal that prevents damage to capacitors included in a noise filter circuit therein which may occur due to a BWB's warp or thermal stresses at soldering time. The noise filter circuit is formed on a noise filter circuit substrate, being a substrate separate from the BWB. The noise filter circuit substrate is connected conductively to part of each of press fit terminals.
Claims13
A power supply terminal for supplying power to a back wiring board, the terminal comprising:
- a terminal body as a base;
- press fit terminals at least part of each of which is housed in the terminal body and which are electrically connected to the back wiring board by being inserted into the back wiring board;
- a noise filter circuit substrate which is separate from the back wiring board and on which capacitors included in a noise filter circuit electrically connected to the press fit terminals are mounted;
- and
- a frame ground terminal of the noise filter circuit is located near the center of the noise filter circuit.
A back board for supplying power, the board comprising:
- a back wiring board on which a pattern for supplying power is formed;
- a power supply terminal including:
- a terminal body as a base, and
- press fit terminals at least part of each of which is housed in the terminal body and which are electrically connected to the back wiring board by being inserted into the back wiring board;
- and
- a noise filter circuit substrate which is separate from the back wiring board and on which capacitors included in a noise filter circuit electrically connected to the press fit terminals are mounted,
- wherein the noise filter circuit substrate is fitted on a surface of the back wiring board reverse to a surface on which the terminal body is located.
