Abstract: Examples provided herein describe a female connector in a computing device that includes a plurality of sensors for determining if a male connector has established a proper connection with the female connector. To do so, in one example, each of the sensors is coupled to an actuator that protrudes into an aperture defined by an inner surface of the female connector. As the male connector is inserted into this aperture, the actuators are pressed down which activates the sensors. Furthermore, the actuators are arranged such that a first actuator is deeper within the aperture than a second actuator. Thus, if the male connector pressed down the first actuator but not the second, a computing device can determine that only a partially connection was made. By using at least two actuators arranged at different depths in the aperture, the computing device is able to detect a proper or improper connection.
