An exemplary orienting structure includes two locating units, a first supporting bump, and a second supporting bump. Each of the locating units includes a first portion and a second portion perpendicular to the first portion. The first supporting bump and the locating units cooperatively define a sliding track configured for slidingly receiving a male connector. A female connector is disposed on the second supporting bump and aligned with the sliding track. The first portions of the locating units function as guides for blocking movement along a first axis of the sliding track. The first supporting bump in cooperation with the second portions of the locating units function as guides for blocking movement along a second axis of the sliding track. When the male connector is slid along the sliding track, the sliding is in a direction perpendicular to both the first and second axes of the sliding track.
