A connection between a terminal 6 located in a hole 5 in the end 3 of a connector 2 and an insulated wire 7 placed on the terminal 6 is made by placing the wire 7 in the hole 5 and pressing the top wall of the hole onto the wire while subjecting the connection to ultrasonic energy so as to melt the insulation and allow the wire to contact the terminal 7; the wall of the hole is also melted by the ultrasonic energy. The wall of the hole may be formed with a protrusion 8 which is pressed by an ultrasonic anvil (30, figure 5, not shown) onto the wire. The wall may have lines of weakness round the protrusion to facilitate its movement onto the wire by the anvil (figures 6, 7, not shown). Notches (5a, figures 8A and 8B, not shown) within the hole may receive molten wire insulation. The wall of the hole may additionally be provided with tabs 14 which, initially upstanding, are bent over so as to retain the material of a protrusion 12, figure 10B, after it has been forced into the hole 5. The material of a protrusion may fit in the hole with clearance to allow for displacement of molten insulation 7b, figure 10B. The top wall of the hole may be provided with lines of weakness, but no protrusions (figures 9A and 9B, not shown) in which case an anvil has protrusions (31) to disrupt only a part of the top surface defined by the lines of weakness. |
