More specifically, since the leaf spring portions 26e and 26f are bent downward, the contact surfaces S13 and S14 are pushed downward in the fixed state. Thereby, the force by which the spring part 26c and the spring part 56c press up and down, and the force by which the spring part 26d and the spring part 56e press up and down become large. Therefore, the frictional force between the spring part 26c and the spring part 56c and the frictional force between the spring part 26d and the spring part 56e are increased.

More specifically, the positioning portion 58 of the plug 50 is a convex portion arranged at a square corner, and the positioning portion 28 of the receptacle 20 is a concave portion having a shape following the positioning portion 58. Therefore, the positioning in the left-right direction is mainly performed by contact between the positioning grooves 28a and 28b and the positioning protrusions 58a and 58b. The positioning in the front-rear direction is mainly performed by contact between the positioning grooves 28c and 28d and the positioning protrusions 58c and 58d.

At this time, if the outer peripheral surface of the cylindrical portion 54b and the inner peripheral surface of the cylindrical portion 26a are in close contact with each other, the positioning portion 28 and the positioning portion 58 may not be in contact with each other.

More specifically, when the temperature rises, the receptacle body 22 and the plug body 52 expand. Since the material of the receptacle body 22 and the material of the plug body 52 are different, their linear expansion coefficients are also different. Therefore, when the temperature rises, a difference occurs between the expansion amount of the receptacle body 22 and the expansion amount of the plug body 52. Such a difference in expansion amount causes a shift in the optical path.

Thereby, the positioning parts 28 and 58 come to expand radially from the center of the square (intersection of diagonal lines). Therefore, the receptacle 20 and the plug 50 are unlikely to be displaced near the center of the square of the positioning portions 28 and 58.

Therefore, these linear expansion coefficients differ greatly, and a large difference tends to occur between the expansion amount of the receptacle cover 26 and the expansion amount of the circuit board 24 at high temperatures. That is, a large stress is likely to be generated between the receptacle cover 26 and the circuit board 24. Therefore, in the optical transmission module 10, the receptacle cover 26 and the circuit board 24 are fixed by an adhesive having a low hardness such as a silicon adhesive.

Abstract

Cette invention concerne un ensemble connecteur et un procédé d'assemblage d'un ensemble connecteur, dans lequel un premier connecteur et un second connecteur peuvent être facilement connectés. L'ensemble connecteur selon l'invention est configuré de telle sorte qu'une première partie de positionnement et une seconde partie de positionnement viennent en contact l'une avec l'autre, ce qui permet d'effectuer un positionnement dans une direction orthogonale à la direction dans laquelle le premier connecteur et le second connecteur sont connectés. Dans un état non fixé dans lequel le premier connecteur et le second connecteur ne sont pas fixés, une première partie de contact et une seconde partie de contact ne sont pas en contact l'une avec l'autre. Dans un état fixé dans lequel le premier connecteur et le second connecteur sont fixés, la première partie de contact et la seconde partie de contact sont en contact l'une avec l'autre. La rotation d'un second élément de retenue commute l'état du premier connecteur et du second connecteur entre l'état fixé et l'état non fixé.
