US 2004/0175992 A1 · Contact slidable structure with a high durability

Abstract

A contact slidable structure is formed between a resilient terminal and a terminal electrode. The terminal electrodes and are disposed on the ceramic element. The resilient terminals and are resiliently deformed and forced to press the terminal electrodes and. The ceramic element has the ceramic body, inner leads and formed inside the ceramic body, terminal electrodes and disposed on the outer surfaces and, and conductive through holes and electrically connecting the inner leads and with the terminal electrodes and, respectively. In the ceramic element, the resilient terminals and are placed slidably on the outer surfaces and of the terminal electrodes and to form the contact slidable structure, and the conductive through holes and are not formed within the contact slidable areas and to the terminal electrodes and, respectively.

Dependent claims

A contact slidable structure comprising:

an element having a body, an inner lead formed in the body, a terminal electrode formed on an outer surface of the body, and a conductive through hole penetrating the body between the inner lead and the terminal electrode to form an electrical connection therebetween;
and
a resilient terminal slidably placed on an outer surface of the terminal electrode to form a contact with the terminal electrode,
wherein the conductive through hole is formed outside a contact slidable area on which the contact slides when the element is connected to the resilient terminal.
