Stop tool

Priority: December 17, 1975; Great Britain; He. 51560/75

The invention relates to an attachment tool, in particular for attaching electrical connectors to cable ends.

From DT-PS 1 465 239 of the applicant is a stop tool known, with two handle units, each with a handle, the handles pivotable with one another and each handle assembly is pivotally connected to a separate pair of lever jaw plates for controlling the movement of the two pairs of lever jaw plates towards and away from each other, and wherein the pairs of lever jaw plates opposite each other at a distance

are held by connecting plates with which the pair of lever jaw plates are pivotably connected.

Each handle is part of a separate handle unit is, is very long for use in power engineering, so that a sufficient mechanical Power is transmitted to the lever jaw plates to attach power connectors to the ends of power cables. For example, one such tool is used for attaching connectors to the ends of cables having a diameter of 16 mm is used.

The stop tool according to the invention is characterized by a first and a second knife, the first Knife is pivotally connected to a pair of lever jaw plates and has a cutting edge extending over the second Pair of lever jaw plates extends addition, and the second knife relative to the second pair of lever jaw plates with this is movably fixed and has a cutting edge which faces the cutting edge of the first knife, so that when the handles are squeezed together, the knives move relative to one another and one arranged between them Cut through the workpiece.

One advantage of this stop tool is that the long handles to the lever jaw plates Attaching a connector to the end of a cable resulting in mechanical power transmission for severing is used by cables with the help of the knife. Furthermore, the knives can be quickly and easily attached to an existing one Tool mountable.

An embodiment of the invention is explained in more detail below with reference to the drawing. Show it:

1 shows a front view of the stop tool in the closed position;

Pig. 2 shows a front view of the tool according to FIG. 1, parts of the tool being shown in the open position;

Fig. 3 shows a cross section 3-3 according to Pig. 1; and Pig. 4 shows a cross section 4-4 according to Pig. 1.

The stop tool is in some respects similar to the tool according to GB-TS 1 057 515, for a better understanding however, the important tool parts are explained.

The striker tool is used to strap electrical connectors to cable ends and includes a first pair of spaced apart Lever jaw plates 4 and a second pair of spaced apart lever jaw plates 2. The lever jaw plates 2, 4 are through Link plates 6 (only one is shown) are held opposite each other at a distance, and both pairs of lever jaw plates are pivotable by bolts 8, 10 with the Connecting plates 6 connected. The lever jaw plates 2, are by hinge points 12, 14 at their respective lower ones

End portions connected to one end of intermediate links 16, each of which forms part of a handle unit. The intermediate members 16, 18 are in turn connected by fastening elements 2Q \ 22 with handles 15, 17, which also belong to the handle units. The handle units are centrally connected to one another by an articulated connection 24-.

The handles 15, 17 control the movement of the jaw plates 2, 4 towards and away from one another. If the Handles 15, 17 are moved apart (see. Fig. 2), cause the intermediate links 16, 18 that the lever jaw plates 2, 4 pivoted about the bolts 8, 10 and thus the upper end portions of the lever jaw plates 2, 4 are moved apart. When the handles are squeezed the lever jaw plates 2, x 4 are pivoted about the bolts 8, 10 so that the upper end portions of the lever jaw plates 2, 4 to move towards each other. A more detailed explanation of the parts of the here explained Pressure tool is contained in the aforementioned GB-PS.

A pivot pin 30 extends between the first pair Lever jaw plates 4 and is held in place by a locking washer 31. On the trunnion 30 a first knife 32 is pivotably arranged. The knife 32 extends from the first pair of lever jaw plates 4 over the outer surface of the tool between the second pair of lever jaw plates 2 and has a cutting edge 36 which laterally outwards over the lever jaw plates 2

Is arranged from. A second knife 38 is fixed movably relative to the lever jaw plates 2 with these, namely by means of a cylindrical extension 42 and a curved recess 44. The extension is in a cylindrical hole set in the front lever jaw plate 2, and the curved recess 44 is located around a pin 46 extending between the second pair of lever jaw plates 2. According to the Pig. 1 and 2 extends the knife 32 behind the knife 38 and lies in a sliding fit between the knife 38 and the rear one Lever jaw plate 2. The knife 38 has a cutting edge 48 facing the cutting edge 36.

When the handles 15, 17 are squeezed together, the cutting edges 36, 48 of the knives 32, 38 become relative to one another to move and cut a cable arranged between the cutting edges. When handles 15, 17 have their open position, the knife 32 is around the pivot pin 30 upwards (see. Pig. 1 and 2) pivotable around the space between the opposite cutting edges 36, 48 to enlarge. This makes it easier to insert a cable between the cutting edges.

One advantage of this tool is that the long handles 15, mechanical force amplification obtained for attaching a connector to the end of a cable for severing is used by cables by means of the knives 32, 38. Perner the knives are quick and easy to attach to an existing one To apply the tool, and in the pall of the tool

according to GB-PS 1 057 515 this practically does not need to be changed. Another advantage is that the knife 32 is pivotably mounted so that large workpieces such . B. thick cables between the cutting edges 36, 48 can be used when the handles 15, '17 have their open division.

Both cutting edges 36, 48 are indeed with a radial cutting profile shown, but straight beveled cutting edges can also be used.
