Definitions

  • the invention relates to a notch pliers for pressing ferrules, cable lugs and connectors onto electrical conductors according to the preamble of claim 1.
  • notch pliers of the aforementioned type in which a coil spring is arranged between the handle-side ends of the pliers legs and in which one leg is of three-shell construction, the two outer shells only extending as far as directly above the point of intersection of the legs and receiving the hinge pin.
  • the third shell of this leg there is a larger bore than the diameter of the hinge pin or an elongated hole for the passage of the hinge pin.
  • the locking projection is arranged on one of the outer shell of the three-shell leg.
  • the locking pawl is held on the other leg and connected to a spring which, when the pawl is deflected, tries to push it back into the starting position.
  • the aforementioned pliers are relatively complex in their construction due to the necessary three-shell design of one leg, the outer shells of this leg having a completely different shape than the middle shell, which in the known solution except for the hole for the hinge pin with the other single-shell leg matches.
  • the invention has for its object to design a pair of pliers of the type mentioned in such a way that, in a simplified structure, only legs connected to the press jaws are provided, which also allow resilience with sufficient suspension travel of the handle ends to enable the locking device to be automatically unlocked by pressing .
  • the said pliers are characterized by the features mentioned in the characterizing part of claim 1.
  • the identical shells of the legs require only a single tool or the corresponding machining processes for the production, whereby the area for receiving the press jaws of one pair of shells may have an additional offset without this offset having an influence on the basic shape of the single shell.
  • the shells of the legs of the pliers thus simultaneously take on the spring action, so that overpressing and automatic unlocking is possible with this overpressing.
  • the new design of the pliers also enables easier assembly since, in the known solution described at the outset, the outer shells of the three-shell leg must be connected to the third shell with a pretension by the hinge pin, so that the latter is on one side of the larger bore or of the elongated hole in the middle shell.
  • the drawing shows an embodiment of the invention.
  • the pliers legs designated as a whole by 1 and 2, are connected to one another at their crossing points by means of a hinge pin 3 and are thereby divided into short leg ends 1a and 2a and considerably longer handle sections 1b and 2b.
  • the individual legs 1 and 2 of the pliers shown each consist of two shells made of flat spring steel 1 'and 2', of which the shells 1 'form the leg 1 and the shells 2' the leg 2. It can be seen that the shells 1 'are held between the shells 2'.
  • the shells 1 'and 2' have a matching design as shown in FIGS. 1 to 3.
  • the pressing tools 5 and 6 can be fastened either by means of bolts 7, in particular in the form of hollow rivets, or else by means of screws if quick and easy replacement of the tools is desired.
  • the shells 1 'and 2' are equipped with longitudinal slots 8, which start from the cheek-side edge and extend over the hole for the hinge pin 3 or enclose it.
  • the slots 8 are arranged in such a way that, when the pliers are in the closed position shown in FIG. 1, they run flush in the direction of the central longitudinal plane of the pliers.
  • the longitudinal slots 8 are expanded in the region between the bore for the hinge pin 3 and their ends facing the handle sections 1b and 2b and are rounded at the end, so that they have the shape of an elongated hole 9 in this region.
  • the spaced-apart shells 2 ' is secured with the one shell pivotally about an axis of rotation 10 locking pawl 11, which is designed in the manner of an angle lever, one arm 11a cooperates with a molded on the legs 1' toothed locking projection 12.
  • the spreading spring 4 articulates, which is also articulated at the other end with the shells 1 '.
  • the spring 4 is designed in a simple manner as a loop spring.
  • slots 1 'and 2' are provided in the shells 1 'and 2', respectively.
  • the arrangement of the bolt 15 can also be reversed in the pair of shells 2 ', which would then engage in the corresponding slot openings 13 of the pair of shells 1'.
  • Fig. 1 shows that in the closed position of the pliers, the pawl 11 has been disengaged from the toothed locking projection 12.
  • the spring 4 has the endeavor to hold the latch 11 in the position shown in FIG. 1.
  • FIG. 3 shows that the pawl lies in the spread position on the other side of the toothed locking projection 12.
  • the leg 11a of the latch 11 slides over the teeth 12 and thus prevents the pliers from opening. Only when the arm 11a has been moved over the locking projection 12 in the course of the further closing movement of the pliers and has reached the position shown in FIG. 1, can the pliers be opened by a spreading movement of the handle ends 1b and 2b.
  • the drawing shows that the new pliers have a very flat design and consist of relatively few parts that can also be easily assembled.
  • the grip sleeves usually provided on the handle sections 1b and 2b are not shown in the drawing.
