<p>An electrical coupling device, for example an electric plug, for effecting electrical connection between an electrically-conducting member of the coupling device, for example a contact pin (22), and the electrically-conducting material of an insulated electrical conductor (13), comprises a base member (1), a cradle (35) provided on the base member (1) and having an internal space for the reception of the conductor (13), which space is defined between a pair of spaced-apart confronting surfaces (36, 37) of the cradle between which, in use of the coupling device, the conductor (13) is held, and a metallic, conductor-piercing means (12), electrically connected to the pin (22), which projects into the space between the confronting surfaces (36, 37). When the conductor (13) is introduced into the space between the confronting surfaces (36, 37), the conductor-piercing means (12) penetrates the electrically-insulating material of the conductor (13) and makes contact with the electrically-conducting material of the conductor while the conductor is held between the confronting surfaces (36, 37). The cradle (35), which may be formed integrally with the conductor-piercing means (12), may be arranged to displace insulating material from the conductor (13) during insertion of the latter into the cradle so that, in the inserted position of the conductor, localised regions of the confronting surfaces (36, 37) bear substantially directly on the conducting material of the conductor.</p> |
