Abstract
Abstract An electronic connector which has a plurality of contacts associated in one or more rows in a connector housing, a shape memory spring associated in the connector housing for driving the contacts, the shape memory spring transmitting a recovery force generated when the shape memory spring reaches its transformation temperature or higher to the contacts while recovering the shape stored when the shape memory spring reaches its transformation temperature or higher and returning to the shape before the shape memory recovery by the spring force of the contact when the shape memory spring reaches below its transformation temperature. Thus, the electronic connector can mount or dismount contacts at each other without inserting or removing force or substantially without inserting or removing force in a simple structure with less number of parts.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
117 words
An electronic connector comprising: a plurality of contacts associated in one or more rows in a connector housing, and a shape memory spring associated in the connector housing for driving the contacts, the shape memory spring transmitting a recovery force generated when the shape memory spring reaches its transformation temperature or higher to the contacts while recovering the shape stored when the shape memory spring reaches its transformation temperature or higher to the contacts while recovering the shape stored when the shape memory spring reaches its transformation temperature or higher and returning to the shape before the shape memory recovery by the spring force of the contact when the shape memory spring falls below its transformation temperature.
Claim 2
Dependent Claim
117 words
An electronic connector comprising: a plurality of contacts associated in one or more rows in a connector housing, and a shape memory spring associated in the connector housing for driving the contacts, the shape memory spring transmitting a recovery force generated when the shape memory spring reaches its transformation temperature or higher to the contacts while recovering the shape stored when the shape memory spring reaches its transformation temperature or higher to the contacts while recovering the shape stored when the shape memory spring reaches its transformation temperature or higher and returning to the shape before the shape memory recovery by the spring force of the contact when the shape memory spring falls below its transformation temperature.
