Abstract

<P>PROBLEM TO BE SOLVED: To absorb effectively a stress acting on a terminal. <P>SOLUTION: In the connector structure 10, a second case 38 is installed on a first case 14 so that an engagement part 42B may be inserted in an insertion engagement chamber 24, and the terminal 30 is inserted in an insertion hole 46. In this case, the terminal 30 is made easy to be elastic deformed by a curved portion 34. Thereby, in the case a fixed column 42 is deviated against an installation tube 20, even if the installation tube 20 is moved against a printed-circuit board 16 by insertion engagement of the insertion engagement portion 42B into the insertion engagement chamber 24, the terminal 30 is elastic deformed so that a stress acting on the terminal 30 can be absorbed effectively. <P>COPYRIGHT: (C)2008,JPO&INPIT
