Description

[0001] The invention relates to a multifunctional hand tool for crimping contact sleeves onto electrical conductors of a cable. The invention particularly relates to a method for crimping contact sleeves onto electrical conductors of a cable.

[0002] Such crimping tools are required for assembling cables with contact sleeves, particularly for field processing, for example when installing control cabinets. Stand der Technik

[0003] DE 10 2010 019 124 A1 discloses an electrically operated stripping and crimping hand tool suitable for stripping cables and crimping sleeves onto wires of stripped cables. In the known crimping hand tool, the stripping device and the crimping device are structurally combined, requiring similar motion sequences of the stripping device and the crimping device for their operation. The structural combination of the two devices should make it possible to provide a hand tool with compact dimensions.

[0004] The considerably complex movement sequences of the structurally combined stripping device and crimping device required to carry out a crimping operation as intended disadvantageously require correspondingly complex mechanics, whereby the crimping hand tool known from DE 10 2010 019 124 A1 is also disadvantageously limited to the stripping of cables and the crimping of wire end ferrules onto their wires.

[0005] FR 2 602 617 A1 discloses a device for attaching a terminal or other connecting element to one end of an electrical cable. The known device comprises a terminal dispenser, which inserts the terminals into a cable guide, on which a cable control is provided for guiding the cable along the cable guide. Along the cable guide, a unit for stripping the insulation from the cable end, a guide for inserting this stripped end into a terminal installed by the dispenser, and a crimping unit for crimping a terminal installed by the dispenser onto the stripped end of the cable are provided in sequence. The device is primarily used in the manufacture of electrical circuits for an aircraft, a motor vehicle, or a machine tool. Aufgabenstellung

[0006] The object of the invention is to provide a hand tool for crimping contact sleeves onto an electrical conductor of a cable that combines multifunctional properties. The hand tool for crimping should, in particular, be easy to handle. In particular, the object of the invention is to provide a comprehensive method for crimping contact sleeves onto electrical conductors of a cable that is easy to implement and particularly suitable for field processing.

[0007] The invention particularly relates to a crimping tool for crimping a contact sleeve onto an electrical conductor of a cable, wherein the crimping tool comprises at least one cable transport device, a cutting and stripping device, a crimping device, and a printing device, which are arranged successively in this order on a cable feedthrough of the crimping tool with an axis. The aforementioned devices are arranged in their sequence in a direction R, which corresponds to a cable feedthrough direction for the cable through the cable feedthrough of the crimping tool.

[0008] The crimping tool is designed in such a way that a cable end of the cable introduced via a cable inlet opening of the cable bushing is fed by the cable transport device in the cable feed-through direction to the cutting and stripping device, the crimping device, and the printing device and is then led out of the crimping tool via a cable outlet opening of the cable bushing opposite the cable inlet opening.

[0009] With the above devices combined and interacting in one tool, it is possible to cut, trim and strip a cable with subsequent crimping of a contact sleeve onto the conductor of a stripped cable end, as well as to document the crimping carried out, after which a multifunctional tool with a variety of functions is provided.

[0010] The crimping tool is particularly easy and intuitive to handle after the processing of a cable end is carried out by inserting the cable end into the cable entry opening in the crimping tool and, after completion, the processed cable end provided with the contact sleeve is led out of the crimping tool at the cable exit opening, whereby the cable exit opening is different from the cable entry opening and is arranged opposite the cable entry opening.

[0011] The cable transport device is suitably provided by means of a friction wheel drive arranged adjacent to the cable inlet opening on the cable duct with at least two wheels opposite one another on the cable duct.

[0012] The friction wheel drive is designed to transport the cable and in particular the cable end to be cut, stripped, crimped with the contact sleeve and printed in the direction R and in the opposite direction to the direction R and to position it in the cutting and stripping device, the crimping device and the printing device for their intended use.

[0013] The friction wheel drive is advantageously configured to detect measured values ​​for determining the cable length, thereby making it possible to cut a predetermined length of a cable fed from a cable reel into the crimping tool, thereby providing a second cable end to be crimped. The crimping tool therefore advantageously allows, particularly during field use, a cable to be laid and connected to be cut from a cable reel with a predetermined, suitable length. For this purpose, the friction drive is suitably provided with a drive unit, which can be provided by an electric motor and can be designed as a stepper motor, wherein the cable length can be determined by detecting the angle of rotation of the wheels or the drive unit of the friction wheel drive.

[0014] The cutting and stripping device has at least two knife blades arranged opposite each other on the cable bushing. The cutting and stripping device is configured such that, in a first position of its knife blades, it severes or cuts the cable, and, in a second position of the knife blades, it cuts into the cable insulation, while the cable conductor is not cut by the knife blades.

[0015] The cutting and stripping device therefore has an advantageous dual function, which allows the cable to be cut and stripped, after which the crimping tool with the cutting and stripping device can be designed to be particularly compact.

[0016] It is clear that the above first position is suitable for cutting the cable to length, and the second position is suitable for stripping the cable and exposing the cable conductor. In the second position, i.e., when stripping the cable, the cutting and stripping device advantageously cooperates with the friction wheel drive, wherein the friction wheel drive provides an axial displacement of the conductor in the opposite direction to direction R for stripping the conductor, so that a section of the cable insulation is pulled from the conductor, which is cut and held by the knife blades.

[0017] Since only the knife blades are moved during operation of the cutting and stripping device, the cutting and stripping device can advantageously be mounted stationary in the crimping tool, thus requiring no additional mechanism besides the drive for the knife blades. The drive for the knife blades can advantageously be provided by a suitable lifting drive, linear drive, or a suitable piezo actuator, as in the crimping device described below.

[0018] The crimping device has at least two pressing elements which are arranged opposite one another on the cable feedthrough, wherein the pressing elements can be suitably driven by a piezo actuator to provide a crimping pressure, by means of which a crimping pressure or a crimping force of the crimping of a pressing element can also be advantageously measured, in particular for use in documenting the crimping and the operating state of the crimping device.

[0019] The printing device is suitably configured to print information identifying the crimping of the conductor with the contact sleeve onto an area of ​​the cable adjacent to the conductor crimped with the contact sleeve. In particular, production order parameters for the crimping process can be documented along with information on the operating status of the crimping tool during crimping, such as temperature and the aforementioned crimping pressure and battery charge level, which are suitable for identifying the quality of the crimping.

[0020] The crimping tool can also be suitably networked for signal and data purposes for documentation purposes, so that the information characterizing the crimping and the operating status of the crimping tool can also be documented in a network-supported manner.

[0021] To detect the above-mentioned information characterizing the crimping process, the crimping tool can be equipped with suitable sensors, including at least one temperature sensor and at least one force sensor. To determine the cable length and to position a cable end, particularly in the cutting and stripping device at the cable feedthrough, a suitable measuring device can also be provided adjacent to the first friction wheel drive and the cutting and stripping device.

[0022] The crimping tool is suitably equipped with a camera for hardware- and software-supported reading of production order parameters for a crimp. The crimping tool can interact with a mobile phone, which provides the production order parameters on its display for reading with the camera. The production order parameters include, in particular, the length, a diameter, a stripping length, and the type of cable, which can be cut by the cutting and stripping device, even from a cable reel, to a length specified by the production order parameters, as well as the contact type of the contact sleeve intended for the crimp.

[0023] Reading in the production order parameters using the camera is particularly advantageous since the production order parameters can be read from paper as well as from a mobile phone using data and information available as a 2D code, QR code or OCR.

[0024] The crimping tool, advantageously designed as a portable handheld tool, suitably comprises a housing with an elongated handle, at one end of which an elongated head is connected, and at the other end a base region. The head accommodates the cable feedthrough with the friction wheel drive, the cutting and stripping device, the crimping device, and the printing device. The housing can suitably be made of plastic or a plastic-coated metal.

[0025] The handle is suitably provided with a waste container for collecting cable trimmings and insulation sections from the cutting and stripping device, as well as a magazine for feeding contact sleeves to the crimping device. The handle also houses a control unit for the crimping tool. The base area suitably houses a battery for power supply.

[0026] The waste container for collecting cable scraps and insulation sections is suitably arranged below the cutting and stripping device in such a way that it extends into the head in the direction of the cutting and stripping device or is accessible via a suitable device for the corresponding supply of cable scraps and insulation sections from the cutting and stripping device.

[0027] The magazine for supplying contact sleeves is suitably designed and arranged such that it extends into the head toward the crimping device and is accessible to the crimping device for the corresponding supply of contact sleeves. The contact sleeves can advantageously be designed as turned contact sleeves. The magazine is configured such that it can accommodate a contact sleeve belt with the turned contact sleeves and feed a contact sleeve to be crimped to the crimping device, after which the magazine functions as a contact sleeve feed device. The magazine can suitably be driven by a stepper motor.

[0028] The crimping tool, with its housing having an elongated handle, at one end of which an elongated head is connected and at the opposite end a foot area, wherein in particular the cable feedthrough with its aforementioned devices is provided in the elongated head, is advantageously designed both ergonomically and functionally and is correspondingly easy to handle.

[0029] Further advantageous details of the crimping tool described above will become apparent from the following description with reference to Fig. 1 , 2 , 3 and 4 out.

[0030] The mobile crimping tool described above is particularly easy to handle for crimping a contact sleeve onto a stripped conductor of a cable end, particularly in field use, and allows particularly simple crimping of the conductor with the contact sleeve.

[0031] The invention therefore also relates in particular to a method for crimping a contact sleeve onto an electrical conductor of a cable using the crimping tool described above, wherein the method uses a method for preparing the crimping which is particularly suitable for field use of the crimping tool using the mobile phone as a mobile control unit.

[0032] In the method preparing the crimping, the production order parameters of the crimping can advantageously be determined and compiled in a first step using the mobile phone, after which, in a second step, the production order parameters determined and compiled by the mobile phone can be displayed on a display of the mobile phone and read by the camera of the crimping tool.

[0033] The length of the cable to be laid between two predetermined connections in the control cabinet and in a predetermined cable guide rail can be particularly advantageously initially optically detected by the mobile phone and then determined using software. For this purpose, the mobile phone can be equipped with a suitable application that allows a photo of, for example, a control cabinet to be displayed on the mobile phone's screen and the connections to be connected to the cable and the cable guide rail to be marked on the screen.

[0034] In this way, the crimping tool can be advantageously easily brought into a first operating state in a third step using the production order parameters, which can include the length and the diameter and the stripping length and the type of cable and the contact type of the contact sleeve, which allows a predetermined crimping of the cable with the contact sleeve characterized by the production order parameters.

[0035] In a fourth step of the process preparing for crimping, it can be suitably checked whether a contact sleeve to be crimped is arranged in its intended position in the crimping device and, if necessary, fed to the crimping device.

[0036] After carrying out the method for preparing the crimping, the crimping tool is set up for assembling a cable by crimping contact sleeves onto both cable ends and for carrying out a corresponding first and second method for crimping a first and second cable end, the individual method steps of which, together with further features of the above method for preparing the crimping, are described in detail in the following description of an advantageous embodiment with reference to Fig. 5 are described.

[0038] The figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for identical, but possibly not identical, elements. Different views of identical elements may be scaled differently.

[0039] Fig. 1A shows a schematic side view of a crimping tool 1 for crimping a contact sleeve 5 onto an electrical conductor 40 according to an embodiment of the invention, together with a cable end of a cable 4 to be crimped and a contact sleeve 5. The crimping tool 1 has a housing that is advantageously both ergonomically and functionally designed with an elongated handle 11, at one end of which an elongated head 10 is connected, and at the opposite end of which a foot region 12 is connected. The housing can suitably be made of plastic or of a plastic-coated metal and accommodates a variety of functional devices within its interior.

[0040] Fig. 1B shows in conjunction with Fig. 1A a section of the crimping tool 1 from a different perspective, namely rotated by 90° from the plane of the drawing and in the opposite direction to the direction R of Fig. 1A , which indicates a cable insertion direction and cable feed-through direction R of a cable 4. Fig. 1C shows a top view of the cable 4 and the contact sleeve 5 of Fig. 1A each in their axial direction. The cable 4 has a conductor 40 provided with insulation 41. The contact sleeve 5 has an inner edge 50 corresponding to the conductor 40 for inserting the conductor 40. The conductor 40 can be a single wire, a wire braid, a core, or a stranded wire. The contact sleeve 5 can, in particular, be a turned contact sleeve 5.

[0041] The elongated head 10 has a central, elongated cable feedthrough 100 that is open on both sides and extends linearly along a central axis A1. The head 10 accommodates in its interior a cable transport device 20, a cutting and stripping device 21, a crimping device 22, for example, a further cable transport device 20, and a printing device 23, which are arranged in this order in the cable insertion direction R along the cable feedthrough 100. The aforementioned first-mentioned cable transport device 20 is arranged adjacent to an opening 101 of the cable feedthrough 100 provided for inserting the cable 4. The two further axes A2 and A3 each extend perpendicular to one another and to the axis A1, with the axis A2 extending centrally through the head 10, the handle 11, and the base region 12.

[0042] The aforementioned devices 20, 21, 22, and 23 each have suitable functional elements that can interact with drives and / or control elements not shown in the drawing for the sake of clarity. Details of the cable transport device 20, the cutting and stripping device 21, and the crimping device 22 are described below with reference to Fig. 3A , B, C and D and Fig. 4A und B described.

[0043] The printing device 23 is arranged adjacent to a cable outlet opening 102 of the cable bushing 100 for printing on the cable 4 crimped to a contact sleeve 5. In the region of the cable bushing 100, it has a printing unit, for the provision of which techniques such as, in particular, inkjet, hot stamping, laser, pad printing, stamp printing, etc. are suitable. Printing can be carried out directly on the cable 4 or indirectly on an adhesive label. For direct printing on the cable 4, the cable 4 is guided past the printing unit by the cable transport device 20. For indirect printing, a label is first printed and then the printed label is applied to the cable 4, for example as a cable flag. It is clear that such a printing device 23 for indirectly printing the cable 4 has a raw label storage for this purpose.

[0044] Suitable printing data and information suitable for identifying the cable 4 and its crimping can include, in particular, signal data from the sensors 31 and 32 described below and further information and further details such as production order parameters of the crimping, which will be explained below in the description of the camera 31 and also with reference to Fig. 5 together with a crimping method according to an embodiment of the invention.

[0045] The elongated head 10 has a first optical sensor 31 and a plurality of further sensors 32, as well as a display device 33 for displaying, in particular, an operating state of the crimping tool 1. The optical sensor 31 is designed as a camera 31 and is arranged adjacent to the opening 102 of the cable feedthrough 100 with its optical axis parallel to the axis A1. The camera 31 and the further sensors 32 interact with an electronic control unit 3, which can be conveniently housed in the handle 11. In addition to the optical display device 33, the crimping tool 1 can also have means for acoustically displaying an operating state.

[0046] The camera 31 is provided in particular for reading data and information in the form of a 2D code, QR code or OCR, such as production order parameters, in particular with a predetermined cable length L and a diameter and a stripping length and the type of cable 4 and the contact type of the contact sleeve 5. For reading data and information in the form of text, the control unit 3 interacting with the camera 31 can have suitable text recognition software. The data and information captured by the camera 31 are suitable for marking the crimping of the cable 4 and thus for printing the cable 4. Further details and features of the camera 31 are described below with reference to Fig. 2 and on Fig. 5 together with a crimping method according to an embodiment of the invention.

[0047] The handle 11 also has a waste container 24 in its interior for collecting cable scraps and insulation sections, and a magazine 25 for feeding contact sleeves 5 to the crimping device 22. The cable scrap and the collected insulation sections collected by the waste container 24 can be collected in the waste container 24 and fed into the material cycle as needed. The magazine 25 is configured such that it can accommodate a contact sleeve belt 250, in particular with rotated contact sleeves 5, and feed a contact sleeve 5 to be crimped to the crimping device 22, after which the magazine 25 functions as a contact sleeve feed device 25. The magazine 25 is configured such that it can accommodate the contact sleeve belt 250 both as a strip-like section and in wound form and feed it to the crimping device 22.

[0048] The waste container 24 is designed and arranged such that it extends in the direction of the cutting and stripping device 21 into the head 10 or is accessible via a suitable device for the corresponding supply of cable scraps and insulation sections from the cutting and stripping device 21. The magazine 25 is designed and arranged such that it extends in the direction of the crimping device 22 into the head 10 and is accessible to the crimping device 22 for the corresponding supply of contact sleeves 5. Further details and features of the magazine 25 are described below with reference to Fig. 4B described.

[0049] Furthermore, a manually operable switching device is provided on the handle 11 as an operating element 30, which interacts with the control unit 3 and by means of whose actuation predetermined operating states of the crimping tool 1 can be provided.

[0050] With the above-described electrical, electronic or electromechanical functional elements, units and devices accommodated in the head 10 and the handle 11, namely the operating element 30, the sensors 31 and 32, the control unit 3, the display device 33, at least one cable transport device 20 adjacent to the cable inlet opening 101, the cutting and stripping device 21, the crimping device 22, the printing device 23, the waste container 24 and the contact sleeve feed device 25, a multifunctional crimping tool 1 is provided which has a multitude of, also variable, possibilities for the complete and comprehensive assembly of a conductor 40 of a cable 4 to be crimped with a contact sleeve 5, wherein a battery 26 is finally accommodated in the base region 12 for its operation.

[0051] The second friction wheel drive 20 is arranged purely by way of example between the crimping device 22 and the printing device 23 and can also be arranged adjacent to the cutting and stripping device 21 and the crimping device 22, between these devices, or adjacent to the first friction wheel drive 20. With a mirror-image arrangement of a further magazine 25 and a further suitable crimping device 22 (not shown in the drawing), both cable ends can also be crimped with contact sleeves 5 upon a single insertion of the cable 4. It is clear that the friction wheel drive 20, the cutting and stripping device 21, the magazines 25, and the crimping devices 22 are suitably arranged on the cable feedthrough 100 and are suitably controlled for this purpose.

[0052] Sensors 31 and 32 are signal-connected to control unit 3 for detecting operating states of crimping tool 1. Additional sensors 32 may be suitable optical sensors, mechanical sensors, and temperature sensors suitable for detecting an operating state of at least one device of crimping tool 1. Electronic control unit 3 may suitably comprise a microcontroller, a microprocessor, and a memory unit, as well as a suitable interface for bidirectional wireless signal and / or data transmission, particularly via Bluetooth.

[0053] The control unit 3 equipped in this way is thus able to monitor and control the operation of the crimping tool 1 using hardware and software, and to log it in the form of data, wherein the software for this purpose can be available on the memory unit of the control unit 3. Furthermore, the control unit 3 can be suitably networked with a mobile control unit 6, which can in particular be a mobile phone 6, using Bluetooth. The mobile control unit 6 can furthermore suitably interact with the camera 31, which will be described below with reference to Fig. 5 together with a crimping method according to an embodiment of the invention.

[0054] With reference to Fig. 1A , B and C, essential elements and devices and their arrangement of the thus multifunctional crimping tool 1 have been described above. In particular, functional details regarding the features of the individual elements and devices of the crimping tool 1 and their interaction during its operation are described below with reference to Fig. 3A , B, C and D and Fig. 4A und B A method for crimping a contact sleeve 5 onto an electrical conductor 40 of a cable 4, in particular using the crimping tool 1 according to an embodiment of the invention, is described below with reference to Fig. 5 described.

[0055] The following is based on reference to Fig. 2 an exemplary modification of the crimping tool 1 is described. Fig. 2 shows a crimping tool 1 according to an embodiment of the invention together with a cable end 4 to be crimped and a contact sleeve 5. The mobile phone 6 is in Fig. 2 not shown and it is here in this regard Fig. 1A The crimping tool 1 from Fig. 2 differs from the execution of Fig. 1A essentially in the arrangement of its head 10 to the handle 11. The handle 11 is in relation to the head 10 compared to the design of Fig. 1A rotated by 180° and arranged offset in the cable feed-through direction R, according to which the crimping tool 1 is ergonomically particularly easy to handle for an operator who prefers handling of the crimping tool 1 as similar as possible to the handling of an electric drill or a cordless screwdriver.

[0056] When operating the crimping tool 1 from Fig. 2 Namely, the cable 4 is inserted into the opening 101 of the cable bushing 100, which is spaced apart from the handle 11. Furthermore, the cable 4 crimped with a contact sleeve 5 is led out of the crimping tool 1 at the opposite opening 102 of the cable bushing 100 directly in the direction R toward the operator.

[0057] In addition, the camera 31 is different from the execution of Fig. 1A arranged adjacent to the opening 101 for inserting the cable 4. In this arrangement, the camera 31 can easily record, in particular, image data of a cable 4 before its insertion into the crimping tool 1, which are also suitable for documenting the crimping process.

[0058] The waste container 24 is comparatively similar to the design of Fig. 1A comparatively small and provided only in the head 10, wherein the waste container 24 for receiving and collecting cable scrap and insulation sections is also arranged adjacent to and below the cutting and stripping device 21.

[0059] Fig. 3A shows an enlarged schematic representation of two friction wheels 200 of a cable transport device 20 of a crimping tool of Fig. 1A and 2The cable transport device 20, suitably provided by at least one friction wheel drive 20, has at least two wheels 200 arranged tangentially to the axis A1, which are designed as friction wheels 200. The friction wheel drive 20 is designed, configured, and arranged such that it engages the cable 4 manually inserted through the opening 201 and rotates, thereby displacing and transporting the cable 4 until a predetermined displaced cable length for proper positioning of the cable 4 is reached.

[0060] The cable length can be determined at the friction wheel drive 20 by detecting the angle of rotation of the friction wheels 200 or a drive unit of the friction wheel drive 20. Alternatively, a direct length measurement can be performed on the cable 4 passing through, for example, by means of a suitable optical or mechanical measuring device 320 arranged adjacent to the friction wheel drive 20 and having additional sensors 32, which is also connected to the control unit 3 for signal and data transmission.

[0061] The friction wheel drive 20 is suitably configured such that it can transport the cable 4 in the cable feedthrough direction R and also against the cable feedthrough direction R. These two transport directions of the cable 4 in the cable feedthrough 100 are used successively during operation of the crimping tool 1, in particular when stripping the conductor 40 at the cable end of the cable 4, wherein the friction wheel drive 20 is advantageously equipped with the device described below with reference to Fig. 3B , C and D described cutting and stripping device 21.

[0062] A further optical or mechanical sensor 32 mentioned above is used in the execution of Fig. 1A and 2Arranged adjacent to the opening 101 and the friction wheel drive 20, by means of which, for example, a first insertion of a cable 4 into the opening 101 can be detected, whereupon a corresponding signal from the sensor 32 can be sent to the control unit 3, so that the crimping machine 1 can be set to a predetermined operating state. For example, in this operating state, the cable transport device 20 and / or the cutting and stripping device 21, etc., can be moved from a rest position to a first working position.

[0063] In addition to the optical sensor 32 described above, another such sensor shown in the drawings Fig. 1A and 2An optical sensor 32 (not shown) can be arranged adjacent to the opening 102 on the cable bushing 100, so that an exit of the cable 4 from the opening 102 can be detected, and after which the crimping machine 1 can also be set to a correspondingly predetermined operating state.

[0064] To indicate an operating state of the crimping tool 1, a display device 33 can be provided on the crimping tool 1 and / or the operating state can be sent, in particular via Bluetooth, to the mobile control unit 6, which can display it and also document it via the network. In particular, a change in an operating state can also be indicated acoustically using a suitable device.

[0065] Fig. 3B shows an enlarged schematic representation of elements of a cutting and stripping device 21 of a crimping tool 1 of

[0066] Fig. 1A and 2together with a cable section of a cable 4 in a rest position P0.

[0067] The cutting and stripping device 21 suitably comprises two knife blades 210 with selectable cutting geometries, wherein the knife blades 210 are advantageously used for cutting or cutting the cable 4 to length and also for subsequently stripping the previously cut cable end, wherein the insulation 41 of the cable end is removed and the conductor 40 to be crimped is exposed. The knife blades 210 are arranged mirror-symmetrically opposite one another to the axis A1 of the cable bushing 100, and the cable 4 is as shown in Fig. 3B shown arranged between the knife blades 210 in the cable bushing 100.

[0068] In the rest position P0, the knife blades 210 are spaced apart from each other and from the cable 4. The cutting and stripping device 21 can be Fig. 3B shown, with its knife blades 210 arranged parallel to the axis A2 on the cable bushing 100. It is clear that the cutting and stripping device 21 with its knife blades 210 can also be arranged parallel to the axis A3 or pivoted to the axis by an angle α of suitably 45°, whereby a particularly compact design of the head 10 is possible.

[0069] The cutting and stripping device 21 is configured such that its knife blades 210 are moved axially toward each other during cutting or cutting to length and during stripping. Depending on the travel path of the knife blades 210, the cable 4 is cut or cut to length, namely when the knife blades 210 are moved together beyond their cutting edge. This position P1, suitable for cutting or cutting the cable end of the cable 4, is shown schematically in Fig. 3C shown.

[0070] During stripping, the knife blades 210 of the cutting and stripping device 21 are moved towards each other by a predetermined amount, so that a gap remains between the knife blades 210 for the conductor 40 to be stripped. This position P2 of the knife blades 210, which is suitable for stripping the insulation 41, is shown in Fig. 3D shown. As stated above, the cutting and stripping device 21 cooperates in a suitable manner with the friction wheel drive 20, which provides an axial movement in the opposite direction to the cable feed-through direction R for stripping the conductor 40, so that a section of the insulation 41 of the cable 4 is pulled from the conductor 40, which is cut and held by the knife blades 210, while the cable 4 with the stripped conductor 40 is pulled out of the cutting and stripping device 21 by the friction wheel drive 20 in the opposite direction to the cable feed-through direction R.

[0071] Since only the cutting and stripping device 21's knife blades 210 are moved during operation, the cutting and stripping device 21 can advantageously be arranged stationary in the crimping tool 1, whereby no further mechanism is required besides the drive of the knife blades 210. Alternatively, a corresponding axial movement of the knife blades 210 of the cutting and stripping device 21 in the cable feedthrough direction R is possible with the cable 4 held by the friction wheel drive 20.

[0072] Fig. 4A shows an enlarged schematic representation of elements of a crimping device 22 of a crimping tool 1 of Fig. 1A and 2 together with a stripped conductor 40 of a cable 4 and a contact sleeve 5, which are positioned in the crimping device 22 as intended for crimping, in a first working position. Fig. 4B , shows elements of a contact sleeve feed device 25 of the crimping tool 1, in which the contact sleeves 5 in the magazine of the contact sleeve feed device 25 are fed to the crimping device 22 in a row on a contact sleeve belt 250. After a crimping operation, the contact sleeve feed device 25 advances the contact sleeve belt 250 by a predetermined belt pitch. The contact sleeve feed device 25 can be suitably driven by a stepper motor.

[0073] The crimping device 22 has a contact belt separating device (not shown), by means of which the next contact sleeve 5 supplied to the crimping device 22 by the contact sleeve feed device 25 can be separated from the contact sleeve belt 250. Furthermore, the crimping device 22 has a contact positioning device (not shown), by means of which a contact sleeve 5 separated by the contact belt separating device and grasped by the crimping device 22 can be positioned in the crimping device 22 for its intended crimping onto a stripped conductor 40 of a cable 4.

[0074] Fig. 4A shows a first working position of the crimping device 22, in which the contact sleeve 5 in the crimping device 22 is arranged as intended at a central position in the cable bushing 100 in axial alignment A1 to the conductor 40. It is clear that the contact connection side faces the already stripped conductor 40, wherein in the working position of the crimping device 22 of Fig. 4A a conductor 40 has already been inserted into the contact sleeve 5 as intended for crimping by means of the friction wheel drive 20.

[0075] The design of the crimping device 22 of Fig. 4A has as pressing elements 220 suitably four mandrels 220, the drive of which in the direction of the arrow from Fig. 4A via a lifting drive. Alternatively, a suitable linear drive, and particularly advantageously a suitable piezo actuator or a suitable spindle stroke axis can each drive a mandrel 220, which advantageously enables process force monitoring of each mandrel 220. The respective drive force can also be implemented in the aforementioned drives by means of toggle levers. The mandrels 220 of the crimping device 22 are suitably arranged pivoted by an angle α of 45° with respect to the two axes A2 and A3, which are perpendicular to each other and to the axis A1, which allows a particularly compact design of the head 10 of the crimping tool 1. It is clear that the crimping tool 1, instead of the four-mandrel crimping device, uses the design of the crimping device 22 of Fig. 4A may also have a two-mandrel crimping device 22.

[0076] The friction wheel drive 20, the cutting and stripping device 21, the crimping device 22 and the contact sleeve feeding device 25 can each have an individual drive as described above, although instead a suitable central drive with corresponding mechanical conversion devices for the respective partial movements to be carried out can also be provided.

[0077] Fig. 5 shows a flowchart of method steps of a method V for crimping a contact sleeve 5 onto an electrical conductor 40 of a cable 4 according to an embodiment of the invention, wherein the crimping tool 1 described above is particularly suitable for use in method V. Furthermore, the method is particularly suitable for carrying out mobile electrical installation work, for example during switch cabinet removal, which is carried out in particular in the field by a professional electrical installation company.

[0078] In the method V, the following steps S01 to S04 of an advantageous method V0 preparing the crimping are first carried out.

[0079] First, in a first step S01 preparatory to crimping the two cable ends of a cable 4, production order parameters are determined, compiled, and suitably prepared for their use in crimping using the crimping tool 1. The production order parameters can be, in particular, a length L of a cable 4 to be laid and installed in a control cabinet, as well as a diameter and a stripping length, the type of cable 4, and the contact type of the intended contact sleeve 5.

[0080] The length L of the cable 4 to be laid between two predetermined connections in the control cabinet and in a predetermined cable guide rail can particularly advantageously be initially optically detected by a mobile phone 6 equipped with suitable hardware and software and then determined with the aid of software. It is clear that the mobile phone 6 is equipped with a suitable application for this purpose, which allows a photo of, for example, a control cabinet to be displayed on the display of the mobile phone 6 and the connections to be provided with the cable 4 and the cable guide rail to be marked on the display.

[0081] In a second step S02 preparing for crimping, the production order parameters determined and compiled in step S01 are captured by the crimping tool 1 using the camera 31. The production order parameters can be in the form of a 2D code, QR code, or plain text and displayed by the application on the mobile phone 6 on its display. It is clear that for this purpose, the camera 31 of the crimping tool 1 is suitably positioned by an operator, and the crimping tool 1 is brought into a suitable operating state using the operating element 30. As an alternative to the production order parameters displayed in step S02 by the mobile phone 6 as a 2D code, QR code, or plain text on its display, these can also be in paper form and can also be read in from paper by the camera 31.The data transmission of the production order parameters from the mobile phone 6 to the control unit 3 of the crimping tool can also be carried out via Bluetooth.

[0082] In a third step S03 preparing for crimping, the production order parameters read in by the camera 31 or via Bluetooth are determined by the control unit 3 using signals and data and evaluated with the aid of software, after which the control unit 3 sets the crimping tool 1 to a first operating state B1, which is suitably displayed on the display device 33 of the crimping tool 1. The first operating state B1 is characterized in that the recording of the production order parameters and their evaluation have been completed and the crimping tool 1 is ready to carry out the assembly of a cable 4 by crimping a first contact sleeve 5 onto a first cable end of the cable 4 and to insert the cable 4 for this purpose.

[0083] In a fourth step S04, which prepares a crimping operation, it is first checked whether, in accordance with the production order parameters, a contact sleeve 5 to be crimped is present at its intended position in the crimping device 22 and, if necessary, a contact sleeve 5 is fed to the crimping device 22 from the contact sleeve feed 25, wherein the contact sleeve 5 is grasped by the crimping device 22 and positioned in the crimping device 22 at a central position in the cable feedthrough 100 in axial alignment A1 with the conductor 40. For details of step S04, please refer to the above description of the crimping device 22 and the contact sleeve feed device 25 with reference to Fig. 4A and B.

[0084] After the steps S01 to S04 of the crimping preparatory method V0 have been completed, the subsequent steps S11 to S17 of a first method V1 for crimping a first cable end of the cable 4 with a contact sleeve 5 are carried out in the method V in the first operating state B1 of the crimping tool 1.

[0085] In a first step S11 for crimping a first cable end with a contact sleeve 5, the cable 4 is inserted by the operator into the cable inlet opening 101 of the crimping tool 1 for crimping with a contact sleeve 5 in the first operating state B1 of the crimping tool 1. The cable 4 is gripped by the friction wheel drive 20 and guided in the cable feedthrough direction R of the cable feedthrough 100 of the crimping tool 1 to the cutting and stripping device 21 and inserted into the cutting and stripping device 21 by a predetermined amount by which the first cable end is cut off.

[0086] In a second step S12 for crimping the first cable end, the cable 4, which has been inserted into the cutting and stripping device 21 by the predetermined amount and positioned accordingly, is cut off by the cutting and stripping device 21, wherein the cut-off length corresponds to the amount of the cable 4 inserted into the cutting and stripping device 21.

[0087] In this way, the flushness of the insulation 41 with the conductor 40 at the cable end is advantageously ensured, so that when stripping the cable 4, a stripped conductor 40 with a desired predetermined length is provided, which is suitable for crimping with a predetermined contact sleeve 5. In the second step S12, the knife blades 210 of the cutting and stripping device 21 are moved from their rest position P0 by Fig. 3B to position P1 of Fig. 3C and returned to position P0. In step S12, the cut cable scrap is also fed to the waste container 24 by a discharge device of the cutting and stripping device 21.

[0088] In a third step S13 for crimping the first cable end, the cable 4 is stripped by the cutting and stripping device 21, wherein the cutting and stripping device 21 cooperates in a suitable manner with the friction wheel drive 20. First, the cable 4 cut in step S12, which remains with its cable end at a defined position in the cable bushing 100 during cutting, is transported by a predetermined amount in the direction R, which corresponds to the length of the first cable end to be stripped. Following this, the knife blades 210 of the cutting and stripping device 21 are moved to the position P2 of Fig. 3D and cut the insulation 41 of the cable 4 down to the conductor 40.

[0089] While the knife blades 210 remain in position P2, the cable 4 with the conductor 40 is transported by the friction wheel drive 20 by the above-determined amount in the opposite direction to the direction R, with the knife blades 210 holding the insulation 41 of the cable 4 so that the conductor 40 is exposed at a predetermined length at the cable end. In step S13, the stripped insulation section is also fed to the waste container 24 by the discharge device of the cutting and stripping device 21. It is clear that step S13 is suitably performed following step S12.

[0090] In a fourth step S14 for crimping the first cable end, the cable 4 is transported by the friction wheel drive 20 in the direction R and fed to the crimping device 22 and axially inserted with the stripped conductor 40 at its cable end into the contact sleeve 5 positioned in the crimping device. Subsequently, the contact sleeve 5 is crimped to the conductor 40 by the crimping device 22. For details of step S14, please also refer to the above description of the crimping device with reference to Fig. 4A referred to.

[0091] Following step S14, the first cable end of the cable 4, crimped to the contact sleeve 5, is transported by the friction wheel drive 20 in the direction R to the printing device 23 in a fifth step S15 for crimping the first cable end. The first cable end of the cable 4 is printed by the printing device 23 with the production order parameters and further information characterizing the crimping. The further information characterizing the crimping is values ​​detected by sensors 31 and 32 of the crimping tool 1, such as temperature and pressure, as well as a suitably monitored charge level of the battery 26, which are suitable for characterizing the quality of the crimping.

[0092] The crimping performed can also be transmitted, with its production order parameters and with its further information characterizing the crimping, in particular via Bluetooth to the mobile phone 6, whereupon the crimping can be documented on the mobile phone 6 and also via the network.

[0093] It is clear that the length of the cable bushing 100 is known and thus also the length of the cable 4 introduced into the cable bushing 100 in step S15. Furthermore, the above steps S11 to S15 are each carried out in a suitable manner during the transport of the cable 4 by means of the friction wheel drive 20 while detecting the displacement of the cable 4 by means of the friction wheel drive 20 or a measuring device 320. For details, reference is made here to the description of Fig. 1 and 3A referred to.

[0094] Following step S15, the first cable end of the cable 4 printed by the printing device 23 is transported in a sixth step S16 for crimping the first cable end by the friction wheel drive 20 in the direction R to a position in which the first already crimped cable end is at a distance along the cable 4 from the knife blades 210 of the cutting and stripping device 21 that corresponds to the length L determined in step S01. The first cable end crimped and printed with the contact sleeve 5 has already emerged from the cable outlet opening 102 of the cable bushing 100. The length L can be determined by a measuring device 320 or, advantageously, directly on the friction wheel drive 20. In this position, the cable 4 is cut off by the cutting and stripping device 21, and in this way the second cable end and the cable 4 with the cable length L are provided.

[0095] Finally, in a seventh step S17, the crimping tool 1 is brought into a second operating state B2 for crimping the first cable end. This operating state B2 and the successful execution of steps S11 to S16 are suitably indicated visually or acoustically, in particular also on the display device 33, after which the cable 4 is completely pulled out of the crimping tool 1 by the operator.

[0096] The second operating state B2 is characterized in that the crimping of the first contact sleeve 5 onto the first cable end of the cable 4 is completed and the crimping tool 1 is ready for the removal of the cable 4 and for the further insertion of the cable 4 for crimping the second cable end of the cable 4 with a contact sleeve 5, wherein in the second operating state, step S04 is first carried out again and a new contact sleeve 5 is accordingly positioned as intended in the crimping device 22 for receiving the conductor 40 of the second stripped cable end.

[0097] After steps S11 to S17 of method V1 have been successfully completed, in method V, in the second operating state B2 of the crimping tool 1, the subsequent steps S21 to S25 of a second method V2 for crimping a second cable end of the cable 4 with a contact sleeve 5 are carried out.

[0098] In operating state B2, in a first step S21, the operator inserts the cable 4 with its not yet crimped second cable end into the cable inlet opening 101 of the crimping tool 1 for crimping with a contact sleeve 5 to crimp the second cable end with a contact sleeve 5. The cable 4 is gripped by the friction wheel drive 20 and guided in the cable feedthrough direction R of the cable feedthrough 100 of the crimping tool 1 to the cutting and stripping device 21 and by a predetermined amount into the cutting and stripping device 21, by which the second cable end is cut off like the first cable end.

[0099] In a second step S22 for crimping the second cable end, the cable 4, which has been inserted into the cutting and stripping device 21 by the predetermined amount and positioned accordingly, is cut by the cutting and stripping device 21, wherein the cut length corresponds to the amount of cable 4 inserted into the cutting and stripping device 21. In this way, it is advantageously ensured that when stripping the cable 4, a stripped conductor 40 with a desirable predetermined length is provided that matches a predetermined contact sleeve 5 for crimping.

[0100] The first S21 and second S22 steps for crimping the second cable end therefore correspond to the first S11 and second S12 steps for crimping the first cable end.

[0101] It is clear that in the above-described sixth step S16 of cutting the cable 4 to length by means of the cutting and stripping device 21, and providing the second cable end and the cable 4 with the cable length L, the above predetermined amount is taken into account by which the second cable end is also cut off in order to ensure that when stripping the cable 4, a stripped conductor 40 with a desirable predetermined length is provided which is suitable for crimping with a predetermined contact sleeve 5.

[0102] In a third step S23 for crimping the second cable end, analogously to the third step S13 described above, the conductor 40 is exposed with a predetermined length at the second cable end by means of the cutting and stripping device 21, for which reason reference is made to the description of step S13 in this regard.

[0103] In a fourth step S24 for crimping the second cable end, the crimping of the stripped conductor 40 with the contact sleeve 5 is carried out analogously to the fourth step S14 described above by means of the crimping device 22, for which reason reference is made to the description of step S14 in this regard.

[0104] In a fifth step S25 for crimping the second cable end, an area of ​​the cable 4 adjacent to the cable end crimped with the contact sleeve 5 is printed, analogously to the fifth step S15 described above, for which reason reference is made to the description of step S15 in this regard.

[0105] Following step S25, the cable 4 with its two crimped cable ends is removed from the crimping tool 1 and the crimping tool 1 is suitably set again to the first operating state B1, wherein step S04 is also carried out again and a new contact sleeve 5 for receiving a conductor 40 of a stripped cable end is positioned as intended in the crimping device 22.

[0106] As described above, the crimping tool 1 is thus ready to crimp a first cable end of a cable 4 with a contact sleeve and to cut the cable 4 to length according to the settings of the crimping tool 1 made by means of steps S01 to S03. It is clear that steps S01 to S03 can also be executed again by the crimping tool 1 and the mobile phone 6 in order to read in new production parameters of a further order for assembling another cable 4.

[0107] It is clear that the crimping tool 1 is also designed such that the above-described first operating state B1 and the second operating state B2 as well as the individual method steps S11 to S17 and S21 to S25 can each also be set manually by an operator by means of corresponding actuation of the operating element 30.

[0108] Although various aspects or features of the invention are shown in combination in the figures, it will be apparent to those skilled in the art—unless otherwise stated—that the illustrated and discussed combinations are not the only possible ones. In particular, corresponding units or feature complexes from different embodiments can be interchanged. Bezugszeichenliste
