When the covering part 45 has an open surface, a high-frequency signal is radiated to the outside through the open surface, so that the signal intensity may slightly change or a small amount of noise may enter from outside. is there. In this case, the male shield connector 10
If the open surfaces of the connector a and the female shield connector 10b are in the same direction, they radiate in the same direction, or noise enters from the same direction. Unevenness occurs in the performance characteristics of the connector side surface, causing an obstacle.
