In contrast, previously, only a device for Aufpres- m sen (not shown) "pods" to the end of a wire or a strand J become known (cf. DE 32 05 413 -. Al). | i

It has in detail: S ¹

- a gripping device, ί;

- which should hold the strand immobile, '

- a pressing device from £ ■

- 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 stripping the strand end, by moving the slide body, the pressing device arrives at the gripping device and, by moving the carriage body further, it reaches the stripped free strand end, after which the pressing takes place. Finally, the slide body is pushed back so that the ejector with an ejector rod presses the strand end provided with the pressed-on sleeve out of the squeezing chamber and the centering chamber. \

/ fO

While left completely open in this known design are the feeding of the "sleeves" to the centering device and the squeezing device as well as the structure of the stripping device, only the following structure is disclosed for the centering device and the squeezing device (both in the claims as well as in the description of the figures}:

- is the movable squeeze chamber that accommodates the "sleeve" can be reduced in cross-section to compress the "sleeve" by

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

- Are arranged around the square pinch chamber around 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

20th

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 Zentrierkammar that a side surface of each segment body forms a side wall of the centering chamber, 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

- with the centering chamber in the closed position on the insertion side of the wire or stranded wire having a blunt

-ΙΟΙ conical, extending from the insertion opening to the inside the centering chamber tapering section and an adjoining section that extends over the rest Length of the centering chamber extending circular cylindrical Section has, and

- With the centering device, in particular with its frustoconical section, a safe insertion of the 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 (exclusively) 1.5 mm χ 10 mm ferrule DIN 46 218 on 1.5 mm NYAF wire with the following features (Company step "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 device:

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 "gehärc 35 dead curves ".

- 11 -

Disadvantages of this known prior art are in particular!

- unavoidable laborious strapping of the wire end sleeves,

* - what the time savings sought there through the auto-

?. 5 matic stripping is considerably in question because of the

* There required manual work (which should be in no way inferior to the "laborious threading of the ferrule" to be avoided),

- not to mention the additional procurement of belt material, which is also left over as waste,

- finally also complicates the storage and

j - because of the considerable dimensions of the sleeve belt

Magazine disc makes the entire device considerably more bulky;
15th

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

- Elaborate, failure-prone structure of the squeeze linkage

j 20 in particular because of the numerous segment bodies and their Storage;

- Separate ejector (the squeezing 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 best very limited or at all impossible adjustability of the device to different sleeve dimensions;

The "Klemmfix 2001" is only intended for a specific wire (1.5 mm NYAF) and a specific end sleeve (1.5 mm χ 10 mm DIN 46 218), which greatly limits its use in operational practice;

- 12 -

- No constant squeezing quality due to the toggle-spring drive the squeezing device and thus possible aging of the spring.

In addition, there are numerous machines for squeezing of cable wire ends with previously specially taped crimp contact elements, which is therefore fed in a laborious manner in the form of a belt
