This is in the direction of movement of the receiving body 14 relative to the pliers head 3 during the closing of the pressing tool positioner 12 slidably mounted relative to the receiving body 14. With the closing of the pressing tool-positioner 12, so the approach of the receiving body 14 to the pliers head 3, an end face 38 of the clamping or blocking element 37 comes to rest on the pliers head 3. As a result of the contact force between the pliers head 3 and the end face 38 is the Clamping or blocking element 37 is acted upon in the direction of the interior of the receptacle 21.
  • the clamping or blocking element 37 has an inclined surface 39 which comes to rest on the underside of the spring arm 26, the detent 28 or the friction element 32 and converts the applied force generated on the end face 38 into a force which the spring arm 26, the Latch 28 and / or the friction element 32 in the direction of the plug 11 acted upon. If the press tool positioner 12 is held in the closed position, the securing device 24 is secured in the secured position as a result of the clamping or blocking element 37.
  • the individual clamping or blocking elements 37a, 37b, 37c, 37d for the securing devices 24a, 24b, 24c, 24d are formed by a common clamping or blocking bar 40.

  • the clamping or locking bar 40 is mounted on the pliers head 3 and in the interior of the receiving body 14 with the securing device 24 interacts. It is possible that between the pliers head 3, the clamping or blocking elements 37a, 37b, 37c, 37d or the clamping or locking bar 40 and the securing device 24, an elasticity is interposed.
  • Fig. 11 to 13 show an embodiment of a pressing tongs 2, in which first with the closing of the pressing tool positioner 12, the securing device 24 is not yet in the secured position. Rather, here the securing device 24 is transferred via the working stroke, ie with the movement of the tool half 8, motion-controlled and automated in the secured position.
  • an actuating member 41 in particular an actuating tappet 42, is attached to the tool half 8.
  • the actuating member 41 extends through the receiving body 14 through or between the receiving body 14 and the pliers head 3 to the receptacle 21st
  • Fig. 12 is an operating position at the beginning of the working stroke of the pressing tongs 2 shown.
  • the tool half 8, the receiving body 14 and the actuating member 41 move together and parallel to the longitudinal axis of the pressing pliers 2.
  • the relative position of a front side 43 of the actuating plunger 42 and the receptacle 21 does not initially change, so that the actuating plunger 42 no securing effect on the arranged in the receptacle 21 plug 11 exerts.
  • the receiving body 14 comes to rest on the tool half 9 or a frame parts 6. With the further passage of the power stroke and acting on the tool half 8 and the receiving body 14 in the pressing direction, the contact between mold half 9 and frame part 6 leads to a relative movement between
  • the receiving body 14 is connected via elongated holes in the direction of the longitudinal axis with the tool half 8 or held elastically to some extent thereto.
  • the said relative movement has the consequence that it also comes to a relative movement between the end face 43 of the actuating plunger 43 and the receptacle 21 with the plug 11 disposed therein.
  • an actuator 41 such as an actuating plunger 42 may also be attached to the frame part 6 or the mold half 9 and extend from above through the receiving body 14 into the receptacle 21, which then over the entire working stroke, a relative movement between the receptacle 21 and can occur the actuator 41.
  • This fuse element 45 can manually, motion controlled by the closure of the press tool positioner 12th or brought into a secured position by the relative movement of the tool halves 8, 9 during the power stroke, in which the plug 11 (possibly in addition another fuse) is secured in the receptacle 21, and / or in a non-secured position be brought, in which the plug 11 is not additionally secured by the securing device 24 in the receptacle 21.
  • the securing element 45 is relative to the recording 21 for the plug 11 limiting cross section of the receiving body 14 relatively movable, said relative movement, for example, greater than 0.01 mm, greater than 0.02, greater than 0.05 mm, greater than 0.1 mm or even greater than 0.2 mm and at the forces acting on the occasion of the movement of the securing element 45 forces (ie in particular the insertion forces and / or removal forces for the plug according to Fig. 3 to 5 , the actuating forces for the actuator 33 according to Fig. 6 to 8 , the manually applied to the pressing tool positioner 12 for closing forces according to Fig. 9 . 10 or acting on the tool half 8 pressing forces) can be brought.

  • the securing device 24 formed with the spring element 25, the latching element 27 and the latching recess 30 is a latching device 46 which latches on the workpiece 10 for the application of sufficient insertion forces or removal forces can be unlocked.
  • the securing device 24 is a locking device 47, which can not be unlocked by the pure application of removal forces. Even in the event that the safety device 24 with the actuating member 33, the actuating shaft 34 and at least one cam 35 is formed, this forms a locking device 47 which frictionally secures the plug 11, wherein for a removal of the plug 11, first to reduce the frictional force, the contact force must be reduced by rotation of the Actuating shaft 34.
  • the receiving body may only have a receptacle 21 and an associated securing device 24. It is also possible that the receiving body 14 has a plurality of receptacles 21a, 21b, ..., in which case only individual receptacles 21 or all receptacles 21 can each be equipped with a securing device 24a, 24b,...

If such a reference number is then used without additional letters a, b,..., This may mean that only one such component or several such components is / are addressed here.
  • the invention has been described on the basis of a particular type of crimping tool 2 having an O-shaped frame and lug-driven tool halves.
  • the use of the invention is not limited to this type of crimping pliers. Rather, the invention may be used in conjunction with any other type of crimping tool, cf. the above-mentioned prior art, or even another pressing tool can be used.
