IMPROVEMENTS RELATING TO ELECTRICAL PLUGS

摘要

An electrical plug, particularly for domestic use for coupling appliances to socket outlet of a mains distribution system, is adapted to be fitted onto an appliance flex or cable without necessitating use of a screwdriver or other tool by virtue of being formed in two parts, namely a body portion (1) formed with terminal pins (4) insertable into the openings of a socket outlet and an insert (2) enterable into a recess (3) in the body portion (1). The insert (2) comprises a cable clamping arrangement (8) and conductor-receiving channels (10) formed with a right-angled bend and each leading to a termination member (19) in which a plunger (20) is axially movable against spring bias, the plungers (20) projecting from the front face of the insert (2). In the body portion (1) of the plug, the recess (3) has in its end wall three bores (18) located and dimensioned to accept the plungers (20) when the insert (2) is entered into the recess (3), and each bore (18) communicates with a terminal pad (17) coupled electrically to a respective one of the terminal pins (4). As the insert (2) is fully entered into the recess (3) in the plug body portion (1), the plungers (20) butt against the terminal pads (17) and are driven back against their spring bias and capture the conductor ends in the termination members (19).
