Abstract

1456968 Jointing by forging; extruding THOMAS & BETTS CORP 20 May 1975 [18 June 1974] 21514/75 Headings B3H and B3P An extrusion tool for deforming a connector 82 about a conductor comprises a reciprocable plunger 24 for extruding the connector 82 through an extrusion orifice 72 at one end of the tool, a pair of movable arms 46, 48 biased into a position in which they block connector receiving apertures 74, 76 communicating with the extrusion orifice 72 and cam means 38 movable with the plunger 24 for moving one or other of the arms 46, 48 away from its associated aperture 74, 76. When the plunger 24 is moved against spring bias by a handle (28) (Fig. 1, not shown) to extrude the connector 82, one of the arms 46, 48 is pivoted against spring bias from its aperture blocking position by a rod 42 movable with the plunger 24. The rod 42 is selectively positionable so that it can contact one or other of the two arms 46, 48. With the aperture 74, 76 unblocked, a connector 82 can then be introduced into it. When the arm 46, 48 returns to its initial position upon rearward movement of the plunger 24, the connector 82 is pushed by the arm 46, 48 into a position adjacent the extrusion orifice 72 where it is supported by both arms 46, 48. The spacing between the free ends 68, 70 of the arms 46, 48 may be regulated. In another embodiment, the rigid arms 46, 48 are replaced by resilient arms (Fig. 8, not shown).
