In contrast, so far there is only one device for pressing on "Sleeves" (not shown) on the end of a wire j or a stranded wire have become known (cf. DE 32 05 413 - A1).

It has in detail:

- a gripping device,

- <ϊί α A \ ^ Τ.ί 4 * «α imVhAtif a / v 1 \ rtVi faa-t-haifan en! 1 - 1:

- a press-on device

- a squeezing device with squeezing chamber,

- an upstream centering device with centering chamber and

- an ejector,
15th

- a stripping device and

- a "sled body" that

- is movable in two mutually perpendicular movements and

- the pressing device and the stripping device wearing.

The stripping device is located when the stranded wire is inserted into the gripping device.

After the end of the strand has been stripped, the pressing device is moved to the gripping device by moving the slide body and by moving the slide body further onto the stripped free strand end, after which the pressing takes place. Finally, the slide body is pushed back so that the ejector with one ejector rod that with the pressed on Sleeve provided strand end pushes out of the pinch chamber and the centering chamber.

- 12 -

While in this known embodiment, the supply of the "sleeves" to the centering device and are left completely open for the squeezing device and the structure of the stripping device, is for the centering device and the squeezing device only the following structure is disclosed (both in the claims and in the description of the figures):

can be reduced in cross-section to compress the "sleeve" by

- Four segment bodies having the shape of straight prisms, the

- so arranged around the square pinch chamber are that a side surface of each segment body forms a side wall of the squeeze chamber, and

- each displaceable along a straight line in a cross-sectional plane perpendicular to the longitudinal axis of the segment body are led; and

the centering device for inserting the end of the wire or strand into the one located in the squeezing chamber "Sleeve" accordingly has:

- In front of the squeeze chamber, four segment bodies in the form of straight prisms in the direction of insertion of the wire or the strand that

- Are arranged around the centering chamber that a side surface of each segment body is a side wall the centering chamber forms, and

- Can be displaced along a straight line in each case in a cross-sectional plane perpendicular to the longitudinal axis of the segment body are performed, and

- whereby the centering chamber in the closed position on the insertion side of the wire or strand has a butt

conical, extending from the insertion opening to the inside the centering chamber tapering section and an adjoining section that extends over the rest Having the length of the centering chamber extending circular cylindrical portion, and

wherein the centering device in particular with its

The stripped end of the strand should also be ensured when individual stranded wires are removed from the longitudinal axis of the strand end protrude to the side.

In this context, there is also an "end sleeve fitting machine" for (only) 1.5 mm χ 10 mm end sleeves DIN 46 218 1.5 mm NYAF wire has become known with the following characteristics (company publication "Klemmfix 2001" from Weiszhar):

- Stripping device:

two knives and a stop with which the cutting depth is to be set precisely so that the stranded wire is stripped is not damaged;

- Tube feeding deviceϊ

via a "sleeve tape" wound on a magazine disc (Sleeve belt) automatic feed of the wire end sleeves to an insertion funnel;

- Pressing device:

a square crimping should achieve a constant squeezing result by means of a toggle lever and constant spring pressure;

- motion control:

Gearbox with magnetic clutch and brake as well as with "hardened Curves ".

- 14 -

Disadvantages of this known prior art are in particular:

- unavoidable laborious strapping of the wire end sleeves, - which calls into question the time savings sought there by the automatic stripping because of the manual work required there (which does not follow the "laborious threading of the ferrule"

uüli. ι_β ι ι

- Quite apart from the additional procurement of belt material, which is also left over as waste, j - ultimately also makes warehousing more difficult and

- because of the considerable dimensions of the sleeve belt

Magazine disc makes the entire device considerably bulky;
15th

- Separate, complex centering device for a safe insertion of the stripped strand end;

- Complex, failure-prone structure of the squeezing device, in particular because of the numerous segment bodies and their

Storage;

- Separate ejector (the QuGt device), which increases the effort and susceptibility of the entire device to failure;

25th

- Not reliable and relatively slow responding control in the form of "hardened curves";

- Difficult, at most very limited or even impossible adjustability of the device to different Sleeve dimensions;

the "Klemmfix 2001" is only for a specific wire (1.5 mm NYAF) and a specific ferrule (1.5 mm χ 10 mm DIN 4 6 218) provided, which greatly limits its use in operational practice;

of cable wire ends with previously specially taped crimp contact-. ^

elements, which are thus fed in a laborious manner in the form of a belt 5;

and have to be processed, known for a long time (see e.g. j; <
