ABSTRACT:
A computer includes a housing and a keyboard unit, the housing having a main circuit board with a socket connector provided thereon. The keyboard unit is detachably mounted on the housing and is provided with a ribbon cable extending into the housing and having a terminating end that is removably insertable into the socket connector. The ribbon cable is provided with a transverse restraining strip that is secured to the ribbon cable longitudinally inwardly of its terminating end and has a pair of outwardly projecting end portions. The housing is formed with engaging grooves for removably receiving these outwardly projecting end portions of the restraining strip. Engagement between the restraining strip end portions and the engaging grooves can prevent sudden removal of the terminating end of the ribbon cable from the socket connector, and thus potential damage to the terminating end when the keyboard unit is detached and pulled away from the housing, by isolating the terminating end of the ribbon cable from an initial pulling force exerted on the ribbon cable by movement of the detached keyboard unit from the housing.
