Definitions

  • the invention relates to a crimping tool for crimping wire end sleeves with two jaws mounted in a flexible swivel bearing, which can be pivoted relative to the swivel bearing in particular via a drive having two hand levers, the drive acting on one end of the jaws and the other ends of the jaws each carry a press jaw which has a single press point which is universally intended to cover a cross-sectional area, the pivot bearing having an alternative spring for the flexibility of the jaws required when pressing larger cross-sections.
  • a crimping pliers of the type described at the outset are already designed as universal pliers and have two pressing jaws which have a single pressing point, that is to say a single nest, for deforming conductors of different thicknesses.
  • This universal pliers can be used to crimp conductors that have a cross-section between 0.5 and 4.0 mm2.
  • the press jaws close largely or completely at the time when the Drive has traveled its maximum distance, for example, the hand levers are maximally compressed.
  • the press point When pressing larger cross-sections, for example 4.0 mm2, the press point remains relatively open, ie the press jaws must end their path earlier, including the conductor material, while conversely the drive covers an identical path in all cases.
  • a flexible pivot bearing is provided on the jaws of the crimping tool.
  • One jaw is firmly connected to the handle, that is, it is formed in one piece with it.
  • a toggle lever drive which can be actuated via the other handle, acts as the drive on the other jaw.
  • the two jaws are pivoted about an axle, for example in the manner of rocker arms.
  • the jaw driven by the toggle lever drive is only pivotably supported with a cylindrical bore on the axle journal, while the other jaw engages around the axle journal with an elongated hole which is arranged parallel to the direction of movement of the press jaws during pressing in the jaw.
  • a horseshoe-shaped alternative spring is pivotally suspended in a pivot pin, the other end of which engages the pivot pin of the two jaws.
  • the alternative spring allows one jaw to dodge relative to the other jaw, and thus one press jaw to dodge relative to the other press jaw, although the identical path is covered on the jaws by the drive.
  • the compressible cross-sectional area is limited to cross-sections between 0.5 and 4.0 mm2.
  • the advantage of this crimping pliers is the arrangement of the pressing jaws, which allow the conductor end and the wire end sleeve to be inserted at the pressing point transversely to the main extension plane of the crimping pliers, so that a taper of the pressed wire end sleeve is avoided.
  • the relative arrangement of the press point is disadvantageous insofar as, for example Difficulties can arise in narrow control cabinets.
  • the horseshoe-shaped alternative spring which is provided in a double arrangement and in association with the one jaw, is considerably stressed when pressing thicker cross sections, so that there is a risk that material fatigue will occur here.
  • the press jaws are arranged on the jaws, but cannot be pivoted relative to them, so that the press jaws take over the scissor movement of the jaws even during the closing process.
  • This scissor movement leads to the formation of a flap on one side, ie the pressed cross-section has no symmetrical shape.
  • Another known universal crimping tool has a jaw driven by a toggle lever drive.
  • the other jaw is divided towards the handle, here a plastic block is arranged in a cuboid housing, which can be pressed together via an end plate on the handle, so that the required path differences on the press jaws can be achieved in this way.
  • the two jaws are swivel-mounted on a common journal without elongated holes.
  • the pivotability of the split jaw is limited between stops, so that there are limits to the compression of the plastic block.
  • the press jaws are articulated here on the jaws and guided against one another, whereby they intermesh like a comb and form an approximately square-shaped pressing point, the axis of which lies in the main plane of extension or direction of the pliers.
  • This arrangement favors the use of crimping pliers in confined spaces, e.g. B. in a control cabinet. It is also advantageous that a larger cross-sectional area of conductors between 0.5 and 6.0 mm2 can already be served with these pliers.
  • the press cross section does not correspond to the desired trapezoidal cross section, but is approximately square.
  • the pressed wire end sleeves have a slightly conical shape, especially when comparatively short wire end sleeves are used which cannot be inserted symmetrically to the articulation points of the press jaws into the pressing point.
  • This conicity also tapers in the exact direction in which the wire end sleeve can be pulled out at its connection point, so that there is a risk that the screw connection will come loose when the screw connection is loosened or the conductor moves.
  • Another known crimping tool which can also be used universally for a cross-sectional area between 0.5 and 4.0 mm2, is based on the scissors principle, ie one jaw forms a part with one hand and the two parts are pivotally connected to each other via an axle pin .
  • the two press jaws are articulated on the jaws and guided against each other and form a pressing point, the axis of which lies in the main plane of extension of the crimping pliers, with which the end face or head end can be pressed.
  • the resilience of bridging the path differences is achieved here in that the jaws each have an open-edged recess from the arrangement of the press jaws in the direction of the handles, in the area of which the journal is arranged.
  • the jaws thus form, as it were, alternative springs.
  • the frontal arrangement of the pressing point is also advantageously provided here.
  • the disadvantage is that the one-piece design of the handles and the jaws allows only a simple lever transmission of the drive, so that the crimping pliers are relatively high Actuation forces required. There is also a risk of material fatigue due to the described resilient or resilient design of the jaws and their load.
  • the spring forces provided by the jaws also depend to a large extent on compliance with tight tolerances in the cross-sections of the jaws. A change in material thickness or even a deviation in the prescribed hardness changes the spring properties of the pliers, so that no reproducible results can be expected with appropriate tolerances.
  • the invention has for its object to develop a universal crimping tool of the type described in such a way that pressing forces defined more uniformly and independently of material differences and tolerances can be reproducibly generated over a large cross-sectional area.
  • a bridge spanning the two jaws is provided, which is arranged at least in the vicinity of the pivot bearing of the jaws, and in that the alternative spring is supported on at least one of the jaws and on the other hand on the bridge.
  • at least the cheek, on which the alternate spring acts is supported on the axle journal so as to be evasive. It is important that the bridge spans the two jaws, i.e. extends beyond the outer contour of the jaws, and that the alternative spring acts on the relevant jaw or on both jaws from the outside, while the axle pin remains free of spring forces.
  • the alternate spring can only be provided on one side, i.e.
  • the crimping pliers allow pressing jaws to be used in the relative positions on the jaws known in the prior art, the front arrangement being of course particularly advantageous. There is also freedom in the choice of drive.
  • a toggle lever drive, a double lever drive, a pneumatic drive or the like can be provided here.
  • Cross sections can range up to the order of 1000 kg.
  • the bridge allows the bridge to be designed, as it were, as a housing, which can cover at least the majority of the jaws, the pressing jaws and part of the hand lever, so that the internal parts are protected on the one hand from dirt and on the other hand the housing of a possible injury to the Operator counteracts when handling the crimping tool.
  • a housing is also aesthetically pleasing.
  • the alternative spring can consist of two identically designed, symmetrically arranged packages each engaging on one of the two jaws made of disc springs. With this arrangement and division, a favorable force / displacement characteristic is achieved, as is required for the application of defined high pressing forces over a large cross-sectional area. Such disc springs give off considerable forces with very small spring travel. None of the crimping pliers known in the prior art permit the use of disc springs as a compensating spring. The characteristic curve known in principle from disk springs is now also used for the present application.
  • the pivot bearing can have one or two axle journals, with at least one of the axle journals being mounted on the jaw in question, for example by means of an elongated hole.
  • both jaws are expediently mounted on an axle pin so that they can be avoided. It is sufficient here to provide an open, approximately semicircular recess.
  • the new universal crimping pliers generally has the advantage that symmetrical movement conditions occur on the jaws, the press jaws and possibly also on the parts of the drive, which has a positive effect on the quality and reproducibility of the crimping of the ferrule.
  • the alternative spring and the joint axis or the joint axes can be arranged in a line transverse to the main direction of extension of the crimping tool.
  • the alternative spring or the two parts of the alternative spring act with their forces on the axis of the pivot pin or pivot pin, so that the jaws are not biased in a certain pivoting direction by the alternative spring in the unloaded state.
  • a slightly axially offset arrangement is not harmful. If the offset takes place in the direction of the press point and the alternative spring is used in the pretensioned state, a certain closing force acts on the jaws or the press jaws in the unloaded state.
  • the bridge can be designed as a housing largely covering the jaws, which of course is designed to be open at the pressing point in the area of the pressing jaws at least in the direction of insertion of the conductor end. Otherwise, the housing can extend into the initial area of the hand lever if the drive has such hand lever.
  • This bridge or this housing-like bridge then allows the parts of the alternative spring to be accommodated in a concealed manner without further ado, which is particularly advantageous for disc springs.
  • the jaws can be driven as a double lever drive.
  • the double translation results in particularly low actuation forces at high defined press forces.
  • the double lever drive can have a common pivot axis which is guided in a recess in the bridge. This ensures that the bridge remains at rest in the center when the hand lever is symmetrically operated.
  • the axle journal can also be guided on the bridge.
  • the two press jaws can extend across the main extension plane of the crimping pliers
  • the pivot pin can be pivotally suspended from the jaws and guided against one another, the pressing point being arranged in the main extension plane for the end insertion of the wire end sleeve. This enables pressing on the end face, which is particularly advantageous for confined spaces.
  • the danger of the taper of the pressed wire end sleeve can be countered by the fact that the guidance of the pressing jaws to one another is particularly stable and designed to meet the requirements.
  • the alternative spring can be switched on under pre-tension between the bridge and the cheek or cheeks in order to allow the necessary high pressing forces to act during the pressing.
  • the bias of the alternate spring can finally be made adjustable.
  • disc springs their conical shape makes it possible in a simple manner to stack them together in the same direction or in opposite directions to form a package in order to influence the spring characteristics.
  • the representation of the crimping pliers in FIGS. 1 and 2 differs from the usual graphic representation insofar as invisible edges are shown with solid lines. These are essentially metal parts. On the other hand, visible edges are shown in dashed lines. These are essentially plastic parts.
  • the crimping pliers are constructed in large areas according to the plate construction, which can be seen from Figure 2.
  • Essential components of the crimping pliers are two jaws 1 and 2, which are formed and arranged symmetrically, on the one hand to a main extension plane 3, which forms the drawing plane in FIG. 1.
  • a main extension plane 3 which forms the drawing plane in FIG. 1.
  • the two jaws 1, 2 are designed in the manner of rocking levers and are pivotably mounted on a journal 5 and can be avoided.
  • the jaw 1 has an elongated hole 6 and the jaw 2 has an elongated hole 7, with which the two jaws 1 and 2 are guided on the journal 5 so as to be avoidable.
  • FIG. 3 shows the shape of the jaw 1 better than FIG. 1.
  • a drive 8 engages at the rear ends of the jaws 1 and 2 for the required swiveling movement of the jaws 1 and 2.
  • a handle 10 is pivotally articulated on the jaw 1 via an axle pin 9.
  • a handle 12 engages the jaw 2 via an axle pin 11.
  • the two handles 10 and 12 are formed as metal moldings and each surrounded by a plastic coating 13, 14.
  • the two handles 10 and 12 are pivoted to one another about common pivot pins 15, in such a way that when the handles 10 and 12 are pressed together, the axle pins 9 and 11 move away from one another or move apart, so that ultimately the jaws 1 and 2 on their other, front ends are pivoted towards each other.
  • a double lever drive is formed.
  • a pressing point 16 is formed, into which the stripped end of a conductor 17 (FIG. 3) with an attached ferrule 18 from the end face into the pressing point 16 in the direction of the line of intersection between the main extension plane 3 and the Vertical center plane 4 can be inserted.
  • the press point 16 is formed by two press jaws 19 and 20, the press jaw 19 being pivotally suspended on the jaw 1 by means of a hinge pin 21.
  • the press jaw 20 is suspended via a hinge pin 22 at the front end of the jaw 2.
  • the press jaws 19 and 20 are guided against each other so that they perform a largely translatory movement despite a largely rotary movement of the hinge pins 21 and 22.
  • the jaws 1, 2 are spanned by a bridge 23 which extends at least in the vicinity of an axis 24 through the journal 5 and transversely to the vertical center plane 4.
  • the bridge 23 encloses the jaws 1 and 2 on both sides.
  • the bridge 23 can be widened or extended to form a housing 25, which not only the jaws 1 and 2, but also to cover or enclose the press jaws 19 and 20 and the part of the handles 10 and 12 facing the jaws 1 and 2.
  • the housing 25 thus performs a protective function in that it accommodates and protects the moving parts. Secondly, the risk of injury to the operator is counteracted. It is understood that the housing 25 is open at the end, that is at the location of the pressing point 16, so that the wire end sleeve 18 can be inserted between the two pressing jaws 19 and 20 here.
  • the bridge 23 or the housing 25 is used for the arrangement, storage and accommodation of an alternative spring 26, 27, which are constructed here in a symmetrical configuration in the form of two packages of disc springs 28. It goes without saying that only a set of disc springs could also be provided, so that the alternative spring is then formed asymmetrically on only one side. However, preference is given to the symmetrical arrangement and design. It is important that the alternative spring 26, 27 acts on the jaws 1 and / or 2 from the outside and presses the jaws 1, 2 in opposite directions against the journal 5 with the aid of the bridge 23.
  • the individual plate springs 28 of the two packages can expediently be threaded onto a headed bolt 29 or 30, the respective head resting directly against the outer contour of the jaw 1 or 2 and transmitting its force there.
  • each packet of the alternative springs 26 and 27 is supported on the bridge 23 and on the housing 25, respectively.
  • This support can also be designed in the form of an adjustable bearing in order to adjust the spring preload of the alternative spring 26, 27. Since the individual plate springs 28 are conical, there is the possibility of threading these plate springs 28 in the same direction or in opposite directions onto the headed bolts 29 or 30 in order to achieve the desired or required characteristic or characteristic curve.
  • the two press jaws 19 and 20 are shown separately, in an extended state, so that their shape can be seen.
  • the press jaw 19 has a bore 31 for the passage of the hinge pin 21.
  • recesses 32 and 33 are provided, which are assigned to projections 34 and 35 on the press jaw 20.
  • Guide surfaces 36 are formed between the recess 32 and the projection 34, while the projection 34 is equipped with corresponding counter surfaces 37. The same applies to the recess 33 and the projection 35. In this way it is ensured that the press jaws 19 and 20 always pivot about the hinge pins 21 and 22 so that the press jaws themselves perform a translatory movement. Tilting or tilting, which could lead to tapering of the pressed ferrule, is avoided.
  • FIGS. 6 to 8 show a second embodiment of the universal crimping tool, which is, however, largely similar or in accordance with the embodiment of FIGS. 1 to 5. Only the housing 25 has a slightly different shape here. Figures 6 to 8 are shown essentially with the aim of clarifying the movements of the individual parts in the various pressing processes.
  • the drive 8 is also here Double lever drive and has the two hand levers 10 and 12. These hand levers 10 and 12 are brought together or pressed together from the open position of the crimping pliers (FIG. 6), with a corresponding end position of the two handles being independent of the relevant cross section of the wire end sleeve inserted into the pressing point 16 and the conductor in FIGS. 7 and 8 10 and 12 is reached.
  • the press jaws 19 and 20 are almost against each other; the stop position is reached when a cross-section of 0.25 mm2 is pressed.
  • the press jaws 19 and 20 are at the maximum spacing from one another.
  • the jaws 1 and 2 have also avoided the pressing direction and have the alternative springs 26 and 27 pressed symmetrically halfway each. The jaws 1 and 2 are thus avoided in the direction of the arrows 42 and 43 and with compression of the alternative springs 26 and 27. While examples in the region of the ends of the cross-sectional area are shown in FIGS. 7 and 8, it is understandable that the same applies correspondingly to each cross-section within the indicated range from 0.25 to 6.0 mm 2.
