Abstract

Official abstract text for this publication.

A discharge device includes a connector portion, an electrode portion, and a housing portion. A voltage is applied to the connector portion externally. The electrode portion discharges by boosting and supplying a voltage from the connector portion. The housing portion houses the connector portion and the electrode portion. The housing portion includes a step portion between the connector portion and the electrode portion. The step portion is, for example, a recess.

First claim

Opening claim text (preview).

The invention claimed is: 1. A discharge device, comprising: a connector portion to which a voltage is applied externally; an electrode portion configured to discharge by boosting and supplying the voltage from the connector portion; and a housing portion housing the connector portion and the electrode portion, wherein the housing portion includes a step portion between the connector portion and the electrode portion. 2. The discharge device according to claim 1 , wherein the step portion includes a recess or a projection. 3. The discharge device according to claim 1 , wherein the step portion includes a recess and a projection, and the projection is disposed in the recess. 4. The discharge device according to claim 1 , wherein the connector portion includes a terminal portion electrically connected to the electrode portion, and the step portion is wider than the terminal portion in a direction intersecting a direction along a creepage distance between the electrode portion and the terminal portion. 5. The discharge device according to claim 1 , wherein the housing portion further includes an upper surface on which the electrode portion is disposed, and a first side surface on which the connector portion is disposed, and the step portion is disposed on the first side surface, or on the upper surface and the first side surface. 6. The discharge device according to claim 5 , wherein the housing portion further includes a second side surface on a side opposite to the first side surface, the electrode portion includes a first electrode closer to the first side surface than to the second side surface, and a second electrode closer to the second side surface than to the first side surface, and a distance between the first electrode and the first side surface is longer than a distance between the second electrode and the second side surface.
