Abstract

ABSTRACT OF THE DISCLOSURE
The invention relates to a tool for connecting cable wires to cutting/clamping contacts. In order to provide a tool for connecting cable wires, in which cutting of the cable end is effected after pressing the cable wire into a contact slot only, a locking device is provided at a plunger, said locking device blocking the longitudinal displacement of the plunger with respect to the housing. A tracer is arranged at the plunger head for releasing the locking device when actuated by the cutting/clamping contact or by a component surrounding the cutting/clamping contact.

Description

~ ~32~7~4 The present invention relates to a tool for connecting cable wires of communication cables to cutting/clamping contacts.
A tool for connecting electrically insulated conductor wires is known from EP 0040307. This tool consists of a two-piece handle, in which a plunger displaceable longitudinally in a slider is arranged. At the front end of the plunger, at the plunger head, a wire cutting device comprising two shear arms is disposed. One swivelable shear arm is provided at the rear end with an oblique longitudinal slot, in which a pin fastened to the handle is guided. A
longitudinal displacement of the plunger leads, thus, to a swivelling movement of the shear arms. For pressing an insulated cable wire into a cutting/clamping contact provided in a connector bank, the plunger head is first set down on the connector bank. The handle is then pressed towards the connector bank, by hand, until the cable wire is pressed into the contact slot of the cutting/clamping contact. The force applied to the handle effects a relative movement between the plunger and the handle as well as between the shear arm of the wire cutting device and the pin fastened to the handle, s~id pin sliding into th~ longitudinal slot and therehy turning the movable shear arm such that a cutting blade provided at its front end cuts off the cable wire.
The above-described coupling process has the disadvantage that faulty operation may occur, wh~reby the cutting process is performed before the wire is introduced in the final position into the clamping slot of the cutting/clamping contact. As a result the shorter cable length produces an insufficient guiding of the cable wire, whereby an inappropriate connection between the conductive core of the insulated cable wire and the cutting/clamping contact is formed. Furthermore, for tnick cable wires, the strike mechanism is released before the cable wire is pressed completely into the contact slot of the cutting/clamping contact and so an inappropriate connection results.

- : `:'` ~': :

~ 132~7~ 4 The present invention is based, therefore, on the object of providing a tool for connecting cable wires of the mentioned species, wherein said tool acts off the cable end and releases the strike mechanism only after the cable wire is pressed into the contact slot, thus a~suring a proper connection.
Accordingly, in the invention there is provided a tool for connecting cable wires of communication cahles to cutting/clamping contacts, said tool comprising: a tool housing; a plunger displaceable longitudinally in said tool housing; a cutting devica for cutting said cable wires, said cutting device being disposed at the head of said plunger and being activated by longitudinal displacement of said plunger to initiate cutting; a locking devic2 disposed proximal said plunger, said locking device blocking the longitudinal displacement of said plunger with respect to said tool housing; and a tracer disposed proximal said plunger head, said tracer releasing said locXing device when actuated by a portion of a cutting/clamping contact or a component surrounding said cutting/clamping contact.
Embodiments of the invention will now be described with referencs to the accompanying drawings in which:
Figure 1 is a side view of the tool, partially in a sectional representation;
Figure 2 is a front view, partially in a sectional representation;
Figure 3 is a view of the tool placed on a connector bank in a side view; and Figure 4 is a view of the plunger head of the tool without the cutting device, in a frontal view ascording to Figure 2. .
The tool 1 comprises a tool housing 12 formed by two half-shells 14, 15 which may be forme~ of plastic or other suitable materials. The tool housing 12 forms a handle 16 provided with an aperture 33 at one front face 32. The two housing half-shells 14, 15 are fastened to each other by ~ ~257~

screws 17. A plunger 2 and a slider 19 are arranged in the handle 16 so that they are longitudinally displaceable.
Furthermore, a rotary knob 21 is provided as a fixing device in the handle 16, and a cutting device 29 is provided at the front end of the plunger 2 at the plunger head 5. A related tool is described in EP 0040307. In contrast to that related tool, th~ plunger 2 of the tool 1 is provided with a locking device 3 arranged between two side walls 24, 25 o~ the plunger .

The locking device 3 consists of a latch 10 and an arm spring 22. The latch 10 is provided with a transverse borehole 23. An axle 26 is inserted into the borehole 23 of the latch 10, and into two transverse boreholes of the side walls 24, ~5 of the plunger 2 such that the latch 10 is arranged rotatably in the plunger 2, as shown partirularly in Figure 4. The arm spring 22 is accommodated on the axle 26, with one arm 27 being inserted into another borehole 37 of the latch lo and the other arm 28 being supported on a transverse wall 30 of the plunger 2. Thereby, the latch 10 accepts a position defined by the loading of arm spring 22, in which the hook-shaped section of the latch 10 engages behind the front wall 34 of the housing shell 15. The tracer bar 9 is hooked into a side wall 31 of the latch 10, and extends up to the front section of the plunger head 50 The tracer 6 is formed by a 90 bend formed in the tracer bar 9 at the plunger head 5. The tracer 6 is mounted between two presser pieces 11 of the plunger head 5.
For connecting a cable wire 35 to a cutting/clamping contact 7 arranged in a connector bank 36, the cable wire 35 is first inserted over the contact slot 38 of the cutting/clamping contact 7. Then, to press the cable wire 35 into the contact slst 38, a force is applied by hand to the handle 16, in the direction of the arrow 39, against the force of the two compression springs 40/ 41 provided in the handle 16, until the cable wire 35 is pressed into the contact slot 38. For cutting off the projecting end of the cable wire 35, ` :
~' ' .

~ ~2~7~

the cutting device 29 is arranged at the plunger head 5. This cutting-off process is effected by the longitudinal displacement of the plunger 2 in the handle 16, as the pin 42 fastened in the handle 16 slides into a longitudinal slot 43 of a shear arm 4 of the cutting device 29 and thereby moves the shear arm 4.
Thus, the cutting device 29 cuts off the projecting end of the cable wire 35 at a predetermined distance from the clamping connection.
Only when the locking device 3 is turned about the axle 26, and the latch 10 placed against the front face 32 of the handle 1~ (whereby the locking device is unlocked) is a longitudinal movement of the plunger 2 in the handle 16 obtained. Turning of the latch 10 is effected by the tracer 6 over the tracer bar 9. The tracer 6 is actuated only when it is guaranteed that the cable wire 35 to be conne¢ted has attained its final position in the contact slot 38. Only then are the tracar 6, and thus the tracer bar 9, moved against the direction of the arrow 39 by support on the component 8 of the connector bank 36. By unlocXing the latch 10 of the locking device 3, the longitudinal displacement of the plunger 2 is released, and the cutting-off process is initiated.
In case of multiple connections, if, e.g., two cable wires are to be connected to one cutting/clamping contact, the latch 10 of the locking device 3 can be unlocked even without actuation of the tracer 6. For this purpose, as shown in Figure 2, a U-shaped clip 44 ~which may be formed of any suitable operable material), is fastened outside of the housing shells 14, 15 ~y arms 45, to form an unlocking device 13. By turning the clip 44 by hand, the central section of clip 44 presses against the latch 10, and thus turns the latch 10 of the locking device 3 inwards such that the force producing the longitudinal displacement of the plunger 2 is released.
In case, however, it is desired that the force producing the longitudinal displacement of the plunger 2 is .~ , ~..~, '' ~ ~32~7~

not released, by either the tracer 6 or by the unlocking device 13, the plunger 2 is fixed by turning the rotary knob 21. The mode of operation of the rotary knob 21 .is described in detail in EP 0040307.
