Electrostatic discharge apparatus for touch key
First Claim
1. An electrostatic discharge apparatus for a touch key having a touch sensing unit and a connector unit extending from one end of the touch sensing unit, the electrostatic discharge apparatus comprising:
- a ground pattern portion, which is included in the touch key and formed on at least one static-electricity introduction path of the touch key, the ground pattern portion comprising;
a first ground pattern included at one end of an inner side of the touch sensing unit and configured to absorb static electricity introduced through an inner side of the touch key; and
a second ground pattern included at one end of an outer side of the touch sensing unit and formed between the touch sensing unit and the connector unit, and configured to absorb static electricity introduced through an outer side of the touch key; and
a conduction-processing portion connected with the ground pattern portion and a main body of a portable electronic apparatus associated with the touch key.

Abstract
An electrostatic discharge apparatus for a touch key. A need for a conductive material or a ground layer included in the touch key is removed and a ground pattern portion is formed to prevent damage caused by static electricity introduced into the touch key. The electrostatic discharge apparatus for a touch key having a touch sensing unit and a connector unit extending from one end of the touch sensing unit includes a ground pattern portion having at least one ground pattern, which is included in the touch key and formed on a static-electricity path of the touch key, and a conduction-processing portion connecting the ground patterns with each other and connected with a main body, thereby removing a need for a ground layer provided along an internal circumference of a conventional touch sensing unit, reducing cost by not including EMI paint on the entire surface of the touch key, and preventing static electricity from being introduced into internal circuits of the touch key by causing static electricity introduced into the ground pattern portion to be discharged without passing through the internal circuits of the touch key, thus improving the stability and durability of the touch key.
