Definitions
- the invention relates to an adjusting device for devices for crimping cable lugs.
- cable lugs have a fastening part, by means of which they are fastened by pressing onto the end of an electrical conductor, and a connecting part, which serves to electrically connect the relevant conductor to another electrically conductive member.
- the cable lugs are pressed in a tool or device which has a pair of back and forth movable jaws in which one or more pairs of appropriately profiled press punches are arranged. More than one pair of punches is provided if cable lugs with different types of fastening parts are to be processed in one and the same device.
- the tool or device can be in the form of pliers or a stationary apparatus.
- the present invention has as its object to improve such an additional stop device in the sense that it can accommodate cable lugs with fastening parts in at least two different lengths and, in an advantageous embodiment, also in two different widths, the change from one length to the other should be feasible with a single simple movement.
- cable lugs 101 or 102 have a connection part A with the length L A or L ' A. which is designed depending on the shape of a cooperating contact element, not shown, and a fastening part B with the length L B.
- the fastening part B contains both a first part B, for pressing against the stripped conductor end, and a second part B 2 for pressing against the insulation of the conductor end part.
- Such cable lugs are known, and it is obvious that it is extremely important for them that the parts B 1 and B z are located precisely in the areas of the pair of punches provided for this purpose during the pressing in the device or tool.
- a tool or device in the form of a cable lug pliers 10 has a pair of handles 11. 12 actuatable jaws 13.14, in which two pairs of cooperating press punches are arranged by means of rivets 16, 17 and screws 18, 18 ', of which only the punches 15 arranged in the jaw 14 are visible.
- the press punches are composed of lamellae u, v, x, y of different thicknesses, some of which have the punching surfaces required for parts B 1 and B 2 , and form other spacing elements between the lamellae mentioned first. This construction is known and is outside the scope of the present invention.
- an adjusting device 20 is connected to one side of the jaw 13, which is connected to the handle 11 to form a rigid device body 19. Because the pliers 10 have two pairs of punches 15a, 15b for the reason mentioned earlier, the device 20 is designed for cooperation with two pairs of punches. The following explanations are limited to the description of a device according to the invention for cooperation with a pair of punches, because devices for several pairs of punches are a simple doubling or tripling, etc. of the relevant basic elements.
- the adjusting device 20 has a receiving section 23 in a housing 21 for the longest possible fastening part B of a cable lug.
- the bottom 22 of a receiving opening with the side walls 23a forms the receiving path 23.
- the receiving section 23 is closed with a fixed stop 22A, in the example shown the end wall, the receiving opening designed as a blind hole.
- a pivot pin 24 is arranged in the housing 21 for mounting an adjustable stop support 25.
- the adjustable stop bracket 25 which can be swiveled in the example shown, is designed as an elongated, flat backdrop, which on one end has an opening 25A for the pivot pin 24, and on the other hand a projection 25B to which a bent actuating handle 25C connects.
- the link 25 has on the longitudinal edge 25C 'facing the receiving section 23 a further, shorter projection 25D, the front edge 25D' facing away from the opening 25A in the installed state at the aforementioned distance L A from the end face 20A intended for connection to the pliers 10 of the housing 21 or the entire device 20.
- a coil spring 27 is inserted, which is so long that it protrudes somewhat from the bore 21A in the rest position. After the link 25 has been installed in the housing 21, the spring 27 is compressed and its protruding end lies against the edge 25B 'of the projection 25B of the link 25.
- the link 25 is acted upon in the direction of the arrow P 1 and the projection 25D is pressed against the bottom 22 with its lower edge 25D ".
- the link 25 has a briskly curved front edge 25E, which is indicated at 25E ' the front edge 25D 'of the projection 25D connects.
- a slot 28 is provided in this housing which is delimited by flat side walls and extends along the longitudinal side facing away from the bottom 22 and the transverse side of the housing 21 facing away from the end face 20A, and its shape is shown in FIG. 4 a side wall 28A is shown.
- the floor 22 can advantageously be designed with two raised side ramps 22a.
- the central region 22b between the two side ramps 22a is then intended for the central reception of cable lugs such as 102 with a narrower connection part A, while cable lugs like 101 with a wider connection part rest on the ramps 22a and are centered by the side walls 23a of the opening 23.
- the projection 25D is preferably dimensioned in the direction of its edge 25D 'in such a way that the link 25 must be raised somewhat against the direction of the arrow P 1 before a short connecting part A can reach the edge 25D'. Thanks to the curved shape of the front edge 25E, this lifting takes place without further ado, but requires a partial overcoming of the force of the spring 27, so that the connection part A, when abutting the edge 25D ', simultaneously from the edge part 25E' adjacent to the projection 25D to the bottom 22 pressed on and the entire cable lug is thereby held.
- a recess 22d can alternatively or complementarily be provided in the bottom 22, into which at least a part of the projection 25D can be received, so that the edge part 25E ', which forms a pressing member, is located just above the bottom 22.
- an opening 21A 'for a retaining screw 18' (FIG. 2) is provided in a bead 21A on the housing 21, onto which a retaining nut 29 can be screwed.
- the retaining screw 18 ' corresponds essentially to the screw 18 and is only a little longer.
- At least one recess 20A ′ is provided in the end face 20A, into which one of the not visible, likewise somewhat elongated rivets fits, which correspond in the jaw 13 to the rivets 16, 17 in the jaw 14.
- the rivets 16, 17 often take the form of spring leaves rolled up into a tube with a central through opening. Then the rivets in the jaw 13 can already end on the side wall 13a of the jaw 13, and short pins which fit into the rivet openings are arranged on the end face 20 instead of the cutouts 20A 'as engagement members (see FIG. 6, pins 20A "). ).
- the device according to FIGS. 2 to 5 is used in the following way.
- one screw 18 is replaced by a longer screw 18 'with nut 29.
- the cable lugs drawn onto a conductor end with the connecting part A are inserted into the open jaw pair 13, 14 from the right (according to FIG. 3) until the front edge of the connecting part abuts, which is the front edge 25D 'of the projection 25D happens. Then the cable lug is pressed in the usual way.
- the housing 21 'of the additional device 20' has the form of a groove 23 'with low side walls 23'a and a flat bottom surface 22' which forms the said receiving path and is closed at the end by an end stop wall 22A 'forming the fixed first end stop.
- the fixed first end stop can also be adjustable, e.g. B. by screwing an adjusting screw 22B from the outside into the wall 22A '.
- the housing 21 ' also has a z. B. by means of rivets 21a 'attached bracket part 210 which engages around the groove 23' from above and below with its two legs 210a, 210b.
- Openings L, M are arranged in both legs 210a, 210b for the slidable mounting of a link 250, which forms the stop support that can be moved in the present case.
- the link 250 has a window or a transverse opening 251 which is essentially the same width as the channel 23 'and has an upper edge 251a and a lower edge 251b.
- the height dimension G of the opening 251 is at least equal to the largest corresponding dimension H (FIG. 1a) in the connection part of a cable lug to be machined.
- the part of the link 250 in which the opening 251 is arranged slides in a corresponding continuous gap N in the bottom wall of the housing 21 'and preferably also in notches in the side walls 23'a.
- the link 250 is provided with an actuation button 25C and a compression spring 27 'is inserted between this button and the leg 210b.
- a projection 250D protrudes from the link 250 in the direction away from the end stop 22A '.
- the projection 250D has a briskly curved edge 250E, the section 250E 'of which adjoins the actual link 250 just above the bottom surface 22'. This position is secured by a stop 250a and the action of the spring 27 '. It can be seen from FIG. 7 that the upper edge 251a of the window 251 is located somewhat below the bottom surface 22 '.
- the housing 21 ' has an end face 20'A for connection to a cable lug pressing device, such as pliers 10 (FIG. 2), an opening 21A "serving to receive the screw 18'.
- a cable lug pressing device such as pliers 10 (FIG. 2)
- an opening 21A serving to receive the screw 18'.
- a short cable lug connecting part abuts the link 250 above the upper edge 251a and is supported by the edge section 250E forming the pressing member and the spring 27 '. pressed against the floor 22 '.
- the area of the link 250 just above the upper edge 251 thus acts as an adjustable second end stop.
- the link 250 is raised by pressing the button 25C 'in the direction of the arrow P 2 until the lower edge 251b lies in the plane of the bottom surface 22', this position being determined by a stop 250b . Then the connection part can be pushed in up to the abutment against the end stop 22A ', whereupon the button 25C' is released. The upper edge 251a presses the connection part against the bottom surface 22 'thanks to the spring 27'. After removing the cable lug from the pliers 10, the link 250 automatically returns to its starting position shown in FIG. 7.
- bottom surface 22 ' can also be provided with side ramps, similar to that in FIGS. 4 and 5, and that on the other hand the device according to FIGS. 4 and 5 can also have pins 20A "instead of the depressions 20A'.
- the link 25 according to FIGS. 4 and 5 can have several projections 25D at a distance and in the device according to FIGS. 6 and 7 several links 250 can be provided at a distance, so that more than two different connecting part lengths can be accommodated.
- Both the device according to FIGS. 4 and 5 and that according to FIGS. 6 and 7 can be built with one, two or even more receiving sections.
- the device according to the invention can also be used with the same advantage in the processing of cable lugs which have a uniform, non-divided fastening part.
