Abstract

PURPOSE:To connect lead wires in a shorter time by a device wherein the lead wires are shaped into such a form that insulating materials join with each other when the distal ends of connection conductors are fitted with each other by a sliding connection member. CONSTITUTION:Connection conductors 5c, 5d circular in section are housed in lead wires 3c, 3d. The distal ends of these connection conductors 5c, 5d are fitted with each other by a sliding connection member 7. An insulating material 6d is wound round the connection conductor 5c to form on its distal end insulation taping with a given inclined surface. Meanwhile, a tubular insulator 9 with a given inclined surface is inserted over the outer periphery of distal end portion of the connection conductor 5d, and then an insulating material 6e is wound round the outer periphery of the insulator 9 to form insulation taping. These two inclined surfaces have the forms joinable with each other, so that the lead wires 3c, 3d may be connected with each other just by fitting them to the connection member 7. In this way, connection of lead wires can be completed in a shorter time.
