Definitions

  • the invention relates to a plier-like device for pressing cable lugs which have a fastening part for fastening to the end of an electrical conductor and an anachoid part for electrical connection to a contact element.
  • the cable lugs are usually pressed in a pliers-like tool or device which has a pair of jaws which can be moved towards and from one another and in which one or more pairs of press punches working together are arranged. More than one pair of punches is provided in order to be able to process cable lugs with different fastening parts in one and the same device.
  • Such pliers is z.8. in EP-A-84200435 (0124919), and has a stop member which like a two Arm-shaped lever is formed which is also pivotally connected to the device body in the region of the articulation point of a pivotable pliers jaw to the device body, for example by being mounted on the same pivot pin as the pliers jaw.
  • the front arm of the lever which extends in the jaw region, has an uninterrupted, straight holding edge
  • the second arm which extends in the opposite direction from the articulation point, is influenced by a driver element and by an end stop element in such a way that the stop member carries out pivoting movements when the pliers are actuated, which in certain work phases bring the front arm with the holding edge in front of the fastening part of a cable lug inserted into the pliers, and in other work phases lead the front arm away from this area. No attachment of the fastening part takes place here.
  • EP-A-84200434 (0125708) describes a cable lug pliers in which a housing is firmly connected to the flank of one pliers jaw and has at least one receiving path for the connecting part of a cable lug, the length of which can be adjusted depending on the length of the processed cable lug.
  • the receiving section is in the form of an elongated chamber which closely encloses the connecting part and is largely free upwards.
  • the connection part is held in the chamber, which follows all movements of the relevant jaw of the pliers due to the fastening of the housing.
  • the present invention has for its object to provide a device in which the position of the processed cable lug is precisely fixed by its connector part is inserted in a receiving member, but it is also achieved that when the jaws are pressed the crimped cable lug automatically into a maximum free one Position regarding both jaws is brought. This is particularly important when it comes to cable lugs that face the connector outwards have jumping spring (with “outwards” is understood here "on the opposite side as where the unpressed connection part protrudes.
  • This object is achieved by means of a device which has the characteristics of claim 1, with advantageous further developments being included in the connected subclaims.
  • the receiving members are rigidly connected to one of the jaws, but are carried by a backdrop which can be pivoted between the two jaws, this backdrop not being pivoted completely out of the area between the two jaws in certain work phases, but rather is controlled by the stop elements in such a way that it remains permanently in this area, even if in different positions.
  • the link preferably has the shape of a one-armed lever that does not extend beyond the articulation point to the rear.
  • a cable lug 101 has a connection part 101A and a fastening part 101B, into which a conductor (not shown) can be inserted from the right in the drawing in order to be held in place by pressing.
  • the Connection part 101A has an outwardly projecting resilient retaining hook 101A J.
  • Such cable lugs are known.
  • a cable lug pliers 10 of known construction has a first jaw 13 and a second jaw 14 which can be actuated by a handle 12.
  • the jaw 13 and a handle 11 are rigidly connected to one another to form an elongated device body 19.
  • the second jaw 14 is pivotably articulated on the first jaw 13 or on the device body 19 by means of a pin 24.
  • the handle 12 is articulated on the one hand by means of a pin 23 to the second jaw 14, and on the other hand 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 occupy the extension 14E of the jaw 14.
  • the pair of jaws and handles is normally held in the open end position shown by a spring, not shown, which is fixed by a stop, also not shown.
  • Three punching elements 40a, 41a, 42a are arranged in the first jaw 13 and three punching elements 40b, 41b, 42b cooperating with them in the second jaw 14.
  • This design of the pliers is well known and is outside the scope of the present invention; pliers of this type are e.g. described in more detail in DE-A 25 55 071.
  • a pivotable link 16 in the form of a one-armed lever is articulated on a flank 13 'of the jaw 13 or of the device body 19 on the pivot pin 24.
  • the backdrop 16 extends parallel to the second jaw 14 and towards its front end 14a, i.e. essentially only in the area in front of the pivot pin 24 forming the articulation point.
  • a driver protrudes from the flank 14 'of the second jaw 14 in the area between the pivot pin 24 and the front end 14a pin 14b which forms a first stop element.
  • an arcuate groove 15 is arranged which has its radius of curvature in the pivot pin 24 and in which the driver pin 14b can move freely.
  • a plate spring 22 is arranged between the outside of the link 16 and the head of the pivot pin 24 and presses the link 16 continuously with the preselected force against the first jaw 13 or against the device body 19, but not against the second jaw 14, whose corresponding flank 14 1 , as can be seen from FIG. 3, is somewhat retracted.
  • the normal frictional force between the mutually facing surfaces of the link 16 and the first jaw 13 or the device body 19 is expediently increased.
  • at least one of these facing surfaces can also be provided with friction-increasing agents such as corrugation, suitable covering, etc., but this measure is not necessary in all cases.
  • the plate spring 24 can either be replaced by any other spring, or a resilient element can be omitted entirely, and the pressing force can only be exerted by the pivot pin 24.
  • the frictional force between the link 16 and the first jaw 13, regardless of how it is caused, has the effect that the link 16 has a tendency not to change its position relative to the first jaw 13, regardless of the position and the movements of the second jaw 14 It is therefore a position-retaining force.
  • the first end position of the link 16 shown in the drawing relative to the second jaw 14 (which in turn is in the open end position) is determined by the engagement of the driving pin 14b with the first end 15a of the groove 15 which is more distant from the first jaw 13.
  • the receiving chambers essentially have the shape of a chamber which tightly surrounds the mentioned connection part and which is also at least partially closed at the top, ie in the direction of the first jaw 13, for example by an edge part 16A of the link 16.
  • connection part 101A of a cable lug 101 can thus be inserted from the cheek side, the length L of the receiving chamber being dimensioned in such a way that the fastening part 101B of the cable lug 101 assumes the position in the longitudinal direction relative to the pair of punches 40a, 40b which is exactly the same in the longitudinal direction Compression is required.
  • pliers of this type tend to be provided with a locking mechanism which only allows the two jaws 13, 14 to open when the predetermined closed end position has been reached.
  • the link L6 is therefore carried along until the closed end position of the jaws 13, 14 is reached.
  • the length of the groove 15 is consequently dimensioned such that the driving pin 14b only in the closed end position of the jaws 13, 14, closer to the first Jaw 13 occupies second end 15b of groove 15. It is obvious that this second end can either be located even closer to the first jaw 13 or that it can also be missing at all, ie the groove 15 can be open at the top. It is also easy to see that the groove 15 can also have any wider shape than that shown.
  • this groove end 15b acts as a further stop element which determines a second end position of the link 16; this second end position is functionally irrelevant, but the second stop element prevents with certainty that the link 16 cannot be pivoted out of its working area (ie contrary to the sense of the arrow P 1 ) even if the position-retaining force is overcome if no cable lug is inserted.
  • the second jaw 14 begins to move away from the first jaw 13 in an opening movement contrary to the direction of the arrow P 1 , the link 16 initially remains in its last position, held by the frictional force of the first jaw 13, and the finished crimped cable lug remains in contact with the stamping element 40a with its fastening part 101B.
  • the other punching element 40b moves away from the cable lug 101 due to the opening movement of the second jaw 14.
  • the driving pin 14b in the course of the opening movement has reached again the first end 15a of the Nute15, it acts again as a stop element and takes the gate 16 with, ie it pivots against the action of the frictional force of the arrow P 1 in the opposite sense.
  • the crimped cable lug 101 is inevitably lifted off from the punching element 40a, even if it may have been clamped quite firmly, and after the jaws 13, 14 have reached their open end position, the link 16 resumes its first end position shown in the drawing which the cable shoe can be easily pulled out of the receiving member 50, for example by pulling on the now connected conductor, after which the device is ready for the next pressing.
  • the receiving chambers 50-52 shown in FIG. 2 have a cross-sectional shape with a central indentation such as 52A for receiving the retaining hook 101 A '. This indentation is of course also exposed in the first end position.
  • FIG. 4 shows an alternative embodiment of a cable lug pliers 10 'which differs in three respects from the embodiment according to FIG. 1.
  • the link 116 has an interchangeable housing 16B which is held in place by means of screws 16C and in which the receiving chambers 50 etc. are arranged.
  • housings or receiving chambers can therefore be used for various cable lug connection parts.
  • a leg spring 22A is arranged on the pivot pin 24 and is anchored in the device body 19 and in the link 116 in such a way that the link 116 is constantly acted upon in the direction of the first jaw 13.
  • the temporary co-operation is omitted slave function of the cable lug 101, which is, however, immaterial.
  • the opening phase is exactly the same as described above.
  • the groove 15 is omitted, and in its place an outstanding pin 15a 'is arranged on the inner surface of the link 116, which in the first end position of the link 116 extends further from the first jaw 13 than the driving pin 14b' on the flank 14 'of the Jaw 14 is located, and like this driving pin 14b 'forms a stop element which replaces the first groove end 1-5a (it has already been mentioned that the stop element formed by the second groove end 15b is essentially not required). It is obvious that the stop element formed by the pin -15a 'can also be designed in other ways, e.g. as an inwardly bent lower edge of the backdrop 116.
  • driver pin can be arranged on the inside of the link and the groove in the flank of the jaw, or other types of spring than a leg spring can be used in the alternative design.
  • the receiving members can also be designed for different lengths of the connecting part in accordance with the aforementioned EP-A-84200434 (0125708).
  • the invention can also be applied to cable lug crimping devices where the movable jaw is driven in a manner other than a handle, e.g. hydraulic.
