Description

The innovation relates to a coaxial cable stripping tool according to the preamble of claim 1.

Generic coaxial stripping tools are known in practice. They serve by means of the two knives to be able to bring in two circumsferent cuts in a coaxial cable. For example, with the second, rear knife an outer protective cover of the coaxial cable can be cut, while at a distance, by means of the so-called first knife simultaneously a deeper incision is made in the coaxial cable, which cuts through both a metallic shield and a shell, so that the soul of this coaxial cable can be exposed. The fact that the two knives are arranged within a removable cassette, the tool can be adapted quickly to different installation situations, for example, to different cable types or adapted to the technical equipment to which the antenna cables are to be connected.

For example, different, so-called Absetzmaße required, ie the lengths on which the outer protective cover is removed and the shield is exposed, or different supernatants are required, so different measures how far the soul exposed and should protrude from their sheath.

The innovation is based on the object to improve a generic tool to the extent that this allows the simplest possible handling and rapid work progress.

This object is achieved by a coaxial cable stripping tool having the features of claim 1. Advantageous embodiments are described in the subclaims.

In other words, the innovation proposes to arrange two cassettes with such knives along the circumference of the cutting channel. The blades are, viewed in the longitudinal direction of the cutting channel, arranged at the same length or at the same height. Circumferential cutting is accomplished by rotating the tool around the coaxial cable. By the two cassettes used results in a significant reduced rotational movement, so that with a single hand movement, without having to embrace the tool, the desired cutting action on the coaxial cable can be achieved.

This is particularly advantageously made possible in that the two cassettes are arranged opposite each other, so that a rotational movement is required by a maximum of 180 ° in order to introduce a complete circumferential section in the coaxial cable. It can be assumed that the knives not only penetrate punctually into the coaxial cable, but linearly along a certain proportion of the cable circumference. In particular, this portion of the cable circumference can be influenced by the knife shape and be made particularly large by a concave arcuate, adapted to the diameter of the respective peripheral section to be performed knife blade. In any case, usually a rotational movement of less than 180 ° is sufficient for a complete circumferential cut. Therefore, a quick turn from the wrist allows the desired settling and creation of the desired supernatant using a proposed tool. The fact that the knives are arranged in the two cassettes in the longitudinal direction of the same length, no separate cuts are achieved, which are offset from each other in the longitudinal direction of the coaxial cable, but the cuts that result from the various cassettes, each complementary to a single , Circumferential cut in the coaxial cable.

Advantageously, the tool can have an elongated housing. The cutting channel extends in the longitudinal direction of the housing. In contrast, to set the case, for example, obliquely or transversely to the coaxial cable, resulting in particular in tight installation conditions, a significant advantage, for example, if a plurality of antenna terminals are arranged closely adjacent to a multi-party LNB or a distributor, a approximately pin-shaped tool, which can be attached longitudinally to the coaxial cable, allow trouble-free work.

Advantageously, the tool have a screw, which makes it possible to screw sleeves or union nuts to antenna connectors, so that these works can be performed without a tool change using the same tool. In known manner, this tool has a screw surface, which is designed as a C-shaped peripheral portion of a hexagon.

It can be advantageously provided that the screw or nut to be handled as much as possible is included, for example, characterized in that the inner contour of the housing portion which forms the screw surface, in its peripheral geometry has 5 corners. Accordingly, all 6 peripheral surfaces of the screw or nut to be actuated are applied. The interruption, which has the C-shaped screw surface, allows the attachment of the tool of the Side to the coaxial cable and then the shortest possible path in the longitudinal direction of the cable until the tool is pushed with its screw on the screw or nut to be operated.

The mentioned interruption in the portion of the housing which forms the screw face, has a so-called leading edge and a so-called following edge at a screw due to the direction of rotation, which serve to limit this interruption. The leading edge is the edge, which represents the front edge in the direction of rotation. In the context of the present proposal, the leading edge is, in particular, the edge which, in the case of a clockwise rotation of a screw, that is to say when the screw is tightened, is the front edge in the direction of rotation. In order to enable an economically advantageous production of the tool made of plastic, a reinforcement of the tool housing may be provided near the leading edge to avoid deformation and to ensure a reliable detection of the screw or nut by means of the tool. This reinforcement can advantageously be provided in the form of a metal pin which is arranged in the screw-surface-forming portions of the housing and is closer to the leading edge than the following edge. By means of this reinforcement of the housing section, a particularly economical design of the tool can be supported with regard to the choice of material and wall thickness of the housing.

Advantageously, the housing may be elongated to allow the mentioned space-saving handling even in tight environments. In this case, the housing can be advantageously unfolded about a hinge axis, which runs parallel to the longitudinal axis of the tool. Also, the cutting channel extends in the longitudinal direction in the housing and is limited by these two hinged housing parts. The tool can thus be opened with comparatively small footprint around the coaxial cable around and attached to the coaxial cable and then closed by the two housing parts are folded. The coaxial cable is now received in the cutting channel of the tool and with the mentioned rotational movement can be introduced simultaneously several circumsferential cuts in the coaxial cable.

In this mentioned foldable embodiment of the tool housing, the hinge can advantageously be realized by means of a metallic hinge pin, which connects the two optionally made of plastic housing parts articulated together. This metallic hinge pin can advantageously form the metallic reinforcing pin already mentioned above, which reinforces in the region of the screw surface the portion of the housing which forms the screw surface.

Apart from the knives provided in the two cassettes, two opposing, so-called outer knives may advantageously also be provided, which are provided outside the cassettes in the tool and also project transversely into the cutting channel. Thus, the possibility is created, regardless of the number of arranged in the cassette knife and over a length which exceeds the length of the cassette, by means of the outer diameter coaxial cable, which have a plurality of layers in several stages.

Irrespective of the possibility of arranging outer knives outside the cassettes, it can be advantageously provided that not only two but in each case more than two knives are arranged one behind the other in the two cassettes. In adaptation to certain installation instructions or to certain types of cable can be generated in this way stepwise several circumsferential cuts with different depth of penetration in the coaxial cable, the coaxial cables are thus discontinued multi-stage.

Advantageously, it may be provided that the cassettes not only provide for a certain distance of the individual cuts, but that they also ensure a certain distance of these cuts from the end of the coaxial cable. For this purpose, it can be advantageously provided that a cassette has a stop projecting into the cutting channel against which the end of the coaxial cable can then be guided. This stop extends advantageously over the entire cross section of the guide channel. Such a large-sized stop facilitates rapid work progress. The second cassette has a receiving trough for this stop, so that the tool can be closed easily. In addition, the receiving trough causes a secure storage of the free end of the stop, so that it can be held against deformation or damage secured supported in the receiving trough.

Advantageously, the tool may have two channels which are provided in the longitudinal direction in the housing of the tool: In addition to the cutting channel may be provided a passageway extending over the entire length of the tool and at the two ends of the tool, in particular advantageously at the two axial Ends of an elongated tool, exit openings for the coaxial cable. The fact that the cutting channel is provided next to the passage, damage to the coaxial cable excluded if this is inserted in the through-channel. For example, it may be provided to first prepare the coaxial cable with the aid of the tool, in which it is inserted into the cutting channel and stripped there. Shortly thereafter, the stripped and appropriately prepared coaxial cable is to be connected to a device, the tool can be attached to the coaxial cable so that the coaxial cable is received in the passageway of the tool. One end of the through-channel is formed by the housing portion, which has the screw surface, so that now, for example, the mentioned screw or nut can be tightened.

At the opposite end of the passage channel, the folding tool can advantageously not only have a simple outlet opening in the form of two smooth-surfaced troughs which together form the outlet opening from the through-channel, but these two troughs can be advantageously designed to Klemmmulden. As an alternative to the operation of hexagonal bolting elements knurled or grooved screw elements can be operated with such clamping wells. The clamping action of a clamping recess can be ensured by the clamping recess having a smaller diameter than corresponds to the outer diameter of the screw elements to be handled, and / or the clamping action can be effected or supported by a profiling of the clamping recess.

Of the two clamping grooves at least one can be profiled transversely to its circumferential direction. This can for example represent an advantageous embodiment of the tool when the two clamping recesses are formed in one piece and the same material from the two housing parts, so that by means of profiling a good power transmission can be ensured by the tool on the screw.

Alternatively, to form a clamping recess in one piece and the same material from a housing part, it can be advantageously provided by an insert which is inserted into the respective housing part. The design as a use, the following advantages arise:

In a first embodiment, for example, be provided to produce the insert of the same material, from which also consists of the respective housing part. In this case, the insert is preferably held replaceably in the housing part. If the insert wear out and the power transmission to the screw be impaired, it can be replaced with a new, not worn insert and again a reliable operation of the screw can be ensured. But even if the insert, which consists of the same material as the housing part, not interchangeable but firmly anchored in the housing part is arranged, for example glued, it may be advantageous to produce the clamping recess as a separate insert and only then to connect to the rest of the housing part so as to allow, for example, a complicated geometry of the clamping trough, for example with a resilient portion, which in a one-piece production such as In the injection molding would not or only with a disproportionate effort to realize.

In a second embodiment, the insert may consist of a different material than the material of the respective housing part. For example, a material can be used which is softer compared to the housing material, for example in the manner of a rubber-like elastomer, so that on the one hand by high frictional forces and on the other hand by the deformability of the clamping, which adapts to a surface profiling of the screw and causes a certain positive locking , high screwing forces can be transmitted from the tool to the screw. However, it is also possible, for example, to use a material which is harder in comparison to the housing material and is therefore subject to less wear in constant contact with the screw elements than if the clamping recess were formed by the material of the housing material. For example, a thermoplastic polyurethane material (TPU), as commercially available under the product name "Desmopan", can be used for such a harder clamping recess.

Also, the mentioned inserts of the second embodiment, which consist of other than from the housing material, either permanently anchored in the respective housing part, for example, be encapsulated by the housing material, or they can be interchangeable held in the respective housing part, so that they wear can be replaced.

The designed as interchangeable inserts clamping grooves can be advantageously held by means of a clamping seat in their respective housing part and levered out by means of a tool, such as a screwdriver, from the housing part. A Einstecktnut, which is provided between the housing part and the insert, can serve to attach the screwdriver or a similar instrument and to facilitate the removal of the insert. During use, the insert becomes stronger due to the pressure forces exerted on the screw element pressed into its clamping seat, so that a comparatively weak clamping seat can be sufficient to hold the interchangeable insert reliably at its respective housing part. At the same time, such a weak press fit facilitates the intentional removal of the insert when the insert is to be replaced.
