Definitions

  • the invention relates to crimping pliers for cable lugs which have a fastening part which is open towards the connecting part, the pliers being provided with a stop element for determining the correct position of the cable lug during processing.
  • Cable lugs have a connection part which is intended for electrical connection to another electrical contact element and a fastening part which is provided for electrical and mechanical connection to the end part of an electrical conductor. While the connecting part can have a wide variety of shapes, the fastening part generally has the form of a tube into which the at least partially stripped end of an electrical conductor can be inserted and can be held in place by pressing the fastening part.
  • the invention relates to crimping pliers for cable lugs, the fastening part of which has the shape of a tube which is also open towards the connecting part.
  • Cable lug pliers have a pair of jaws which can be moved towards and from one another and can be actuated by a pair of handles and in which at least one pair of cooperating press punches or punching elements is arranged. It is already known to arrange a fixed stop member on the flank of one of the jaws, following a press punching element, against which a cable lug inserted into the pair of punches, e.g. with the end of the fastening part facing the connecting part, if it is in the correct processing position in the pair of punches. This has the disadvantage that the fact that the length of the fastening part increases during the pressing is not taken into account, and in particular when the fastening part is covered with an insulating sleeve made of plastic.
  • the present invention has for its object to provide a cable lug pliers with an end stop member, which takes into account the extension of the fastening part that takes place during the pressing and at the same time also holds an inserted cable lug by force before the actual pressing.
  • cable lugs 101 or 102 have a connection part A and a fastening part B, into which a conductor can be inserted from the right in the drawing in order to be held in place by pressing.
  • the fastening part B is also to the left in the drawing, that is towards the connection part A, open and ends there with an end edge C.
  • the fastening part B of the cable lug 102 according to FIG. 1b has a plastic sheath B ′ which, when pressed, expands even more in length than the metal part located therein.
  • Such cable lugs are known.
  • a cable lug pliers 10 or 20 of known construction has two jaws 13, 14 which are actuated by two handles 11, 12.
  • One of the jaws, jaw 13, and one of the handles, handle 11, are rigidly connected to one another to form an elongated device body 19 with an inner peripheral edge 19 '.
  • the other jaw 19 is articulated to this device body 19 by means of a pin 24 for pivoting about an axis K, the pivot axis of the pair of jaws.
  • the other handle 12 is articulated on the one hand by means of a pin 23 to the jaw 14, and by means of a pin 32 to one end of a connecting bracket 30.
  • the connecting tab 30 is pivotally connected at its other end to the device body 19 by means of a pin 31.
  • the pin 23 is on a rear, i.e. beyond the pin 24 located extension 14 'of the jaw 14. It thus has an unchangeable position both with respect to the handle 12 and with respect to the jaw 14, and moves when the strap handle 12 is actuated along a circular path with the center in the pin 24.
  • the pair of jaws and handles becomes normal in from a spring (not shown) kept open state (Fig. 4).
  • Two or three punching elements 40a, 41a and 42a are provided in the jaw 13, and punching elements 40b, 41b and 42b which cooperate in the jaw 14 are provided.
  • the construction of the actual pliers is known and is outside the scope of the present invention.
  • a pair of pliers of this type is e.g. described in more detail in DE-A-25 55 071.
  • a pivotable stop member 15 is articulated on one flank of the device body 19, which is designed as a link in the form of a two-armed lever, which is parallel to the Device body extends in the longitudinal direction.
  • the front arm 15a extends from the articulation point of the link 15 to the front end of the pair of jaws 13, 14 and the rear arm 15b extends to the handles 11, 12.
  • the link 10 can also be articulated elsewhere in the area or in the vicinity of the axis K to the device body 19 for pivoting about an axis parallel to this axis, for example at point N (FIG. 2).
  • the front arm 15a of the link 15 has a straight holding edge 17 facing the punching elements 40a etc. in the device body jaw 13, and the rear arm 15b has on the opposite side, i.e. the. Articulated handle 12 facing, an engaging edge 16, which is designed in two parts in the examples shown, the part 16b is stepped or offset relative to the part 16a to the device body handle 11.
  • a first driver in the examples shown the slightly protruding pin 23, is for engagement with the part 16a (FIG. 4)
  • a second driver in the examples shown the slightly protruding pin 32, is for engagement with the part 16b ( Fig. 2) provided.
  • drivers provided separately for this purpose can also be arranged, e.g. at points D (FIG. 4) and / or E (FIG. 2), part 16b possibly being able to be extended somewhat towards the front.
  • a cable lug such as 101 is inserted into a punching element such as 40b in the articulated jaw 14 with the pliers open according to FIG. 4, specifically from the opposite side to where the link 15 is located (that is to say, for example, from above in FIG. 3), until it abuts the arm 15a with its edge C, the flat connecting part A sliding over the holding edge 17.
  • This is achieved by appropriate arrangement of the mutual position of the elements 15 ', 16 and 17.
  • the stripped end of a conductor L is now inserted into the fastening part) B until this conductor end also abuts the arm 15a.
  • the link 15 thus serves with its arm 15a as an end stop for both the cable lug and for the conductor inserted therein, and protruding the stripped conductor end L 'from the fastening part B of the cable lug, as shown in FIG. 1a, cannot occur.
  • a pressing operation is then carried out in the usual way, in that the articulated handle 12 in the direction of arrow P2 (FIG. 4) is approximated to the device body handle 11, with the result that the pin 23 forming the first driver is formed in the direction of arrow f 3 moved into the position shown in Fig. 2.
  • the engagement surface part 16a is relieved and the link 15 is pivoted by the action of the spring 22 or 22 'in the direction of the arrow P 1 , as a result of which the edge 17 presses the connecting part A onto the punching element 40a, which has now been approximated.
  • the second driver performs a circular movement opposite to the circular movement of the first driver, specifically around the pin 31.
  • it can also be arranged at another point E of the handle 12 between the pins 23 and 32, and it can be seen from the drawing that the engaging edge 16 in this case is uniform, ie without Gradation, can be performed.
  • the second driver which has the function of pivoting the front arm 15a of the link 15 in the final phase of a pressing operation from the area of the punching elements 40a, 40b etc.
  • the second driver forms a link which, in the last pressing phase, pivots the link 15 in the opposite direction than it did in the initial phase through the cooperation of the first driver and the spring 22 or 22 '.
  • the invention is not limited to pliers in which the articulated handle 12 is connected to the device body 19 by means of a connecting strap.
  • 5 shows a cable lug pliers according to DE-A-26 02 491, which has been provided with the stop element 15 according to the invention.
  • a cam member 21 is installed in the device body 19 and is scanned by a cam follower member 21 a or 21 b provided on the handle 12.
  • the link 15 or its front arm 15a is slightly extended forward so that the second driver 18 can be attached to the end face of the jaw 13.
  • the engagement edge 16 merely serves to engage the pin 23 forming the first driver, and is therefore undivided.
  • the part 16a of the engagement edge 16 in the embodiments according to FIGS. 2 to 4 and the engagement edge 16 in the embodiment according to FIG. 5 forms an engagement member for the first driver.
  • the part 16b of the engaging edge 16 in the embodiments according to FIGS. 2 to 4 and the front part 17 'of the holding card 17 in the embodiment according to FIG. 4 forms an engagement member for the second driver.
  • the front arm 15a can also be made shorter than shown, e.g. so that he only operates the punching element 42b or the punching elements 41b and 42b.
