Description

TECHNICAL FIELD

[0001] The present invention relates to a crimping jaw device, a crimping machine and a method for establishing a crimping connection. BACKGROUND

[0002] For establishing a crimping connection in a crimping machine, usually at least two crimping tools are used which are arranged in the crimping machine. The two crimping tools are arranged opposite to each other on a vertically movable crimping jaw and on a generally stationary further crimping jaw, also called an anvil. The area between the two crimping tools is often referred to as the crimping area. The crimping machine is usually constructed as a toggle crimping machine with a vertically movable anvil.

[0003] Crimping connections are mainly provided with single or multi-core cables and connectors, such as plugs, eyelets or sockets. During crimping, the cable is arranged at least partially at the connector and is connected to the connector by a section of the connector which is plastically deformed.

[0004] DE 28 20 690 A1 discloses a crimping machine for establishing a crimping connection with a frame arranged on a base plate. The crimping machine has a movable die unit with crimping tools and a movable anvil. The movable anvil is horizontally movable by means of an anvil displacement mechanism and is coupled with the movable die unit. A similar type of crimping machine is also disclosed in US 4,682,400 A.

[0005] The disadvantage of these known solutions is that the anvil which is horizontally movable relative to the crimping tools cannot be stably held in a horizontal position nor in a vertical position, so that a crimping connection of high precision and reproducibility cannot be established. When the anvil is horizontally moved, the feeding of the contact or connector is also increasingly difficult. SUMMARY

[0006] Against this background, it is an object of the present invention to overcome one or more of the disadvantages of the prior art. In particular, it is an object of the present invention to propose a crimping jaw device for a crimping machine which is constructed in a space-saving and stable manner and which can be easily arranged in a crimping machine. It is a further object of the present invention to propose a crimping machine which enables a crimping connection of high precision and a method for reproducibly establishing such a precise crimping connection.

[0007] The crimping jaw device for a crimping machine according to the present invention comprises an anvil which is constructed as a first movable crimping jaw and a first drive device, wherein the drive device has a first drive, and a base structure. In addition, there is a wedge jaw which is movable and connected with the first drive of the first drive device, wherein the wedge jaw can be positioned between the first movable crimping jaw and the base structure.

[0008] The first movable pressure jaw, often also referred to as an anvil, is movable from a locked position into a crimping position. In the crimping position, the first movable pressure jaw is configured such that it can interact with a crimping tool to establish a crimp connection. In this regard, the first movable pressure jaw is stabilized and rigidized by means of a wedge jaw positioned between the base structure and the first movable pressure jaw, so that a plurality of crimp connections can be established in a repeatable and highly precise manner by means of the crimping jaw device in repeated establishment cycles. The crimping jaw device can be simply and stably arranged on a crimping machine and can also be arranged as an upgrade kit on an existing crimping machine. The wedge jaw is movable from a working position into a rest position by means of a drive device, wherein the wedge jaw is in an active connection with the first movable pressure jaw in the working position and thereby stably supports the first movable pressure jaw, preferably when it is in the crimping position. In the rest position, the wedge jaw is detached and spaced apart from the first movable pressure jaw, so that it can move freely, in particular between the crimping position and the locked position.

[0009] Preferably, the first movable pressure jaw is vertically movable, and the wedge jaw is movable, in particular substantially orthogonally, to the first movable pressure jaw. Typically, a crimping tool is arranged on the first movable pressure jaw, wherein the crimping tool at least partially delimits a crimping area of the crimping jaw device. The vertical movement of the first movable pressure jaw enlarges the crimping area in the crimping jaw device of the present application, so that the arrangement of cables and connections can be simplified. This allows the size of the region of the first movable pressure jaw opposite the crimping area to be reduced, so that the overall size of the crimping jaw device can be set in a space-saving manner.

[0010] Advantageously, the base structure of the crimping jaw device is a plate-like or profiled connection structure, so that the overall rigidity of the crimping jaw device can be increased. A plate-like connection structure allows a compact configuration and an increased self-weight, so that the crimping jaw device can be stably positioned on a base. A profiled connection structure has a high rigidity, but can reduce the self-weight of the crimping jaw device.

[0011] Preferably, the first drive device is a pneumatic drive device configured to move the wedge jaw between its working position and its rest position. For example, the pneumatic drive device comprises a double-acting guide cylinder, by means of which the wedge jaw can be continuously moved between its working position and its rest position, and the positions in and between which the working position and the rest position can be precisely adjusted. For example, the double-acting guide cylinder has an overall linear guide and comprises a gas chamber and a piston rod as a first drive for linearly moving or displacing the wedge jaw, so that the positions in and between the working position and the rest position can be continuously adjusted.

[0012] Alternatively, the first drive device is a linear drive configured to move the wedge clamp between its working position and its rest position. For example, the linear drive comprises a screw and a nut in operative connection with the wedge clamp. The screw is driven by the first drive such that the wedge clamp can be moved linearly between its working position and its rest position and such that the positions in and between the working position and the rest position can be adjusted precisely.

[0013] Preferably, the first movable pressure clamp is connected with the first drive of the first drive device. Thereby, the first movable pressure clamp can be moved by means of the first drive of the first drive device in addition to the wedge clamp. Thereby, both movements can be performed simultaneously, so that an efficient and cost-effective drive device can be provided.

[0014] Advantageously, the first drive of the first drive device is configured to move the first movable pressure clamp from the locking position to the crimping position while moving the wedge clamp from the rest position to the working position. Thereby, not only the position of the wedge clamp in and between the working position and the rest position can be adjusted, but also the position of the first movable pressure clamp in and between the locking position and the crimping position can be adjusted precisely.

[0015] In particular, the first movable pressure clamp is connected with the wedge clamp by means of a transmission. Thereby, the first movable pressure clamp is spaced apart from the wedge clamp and can be moved by means of the transmission. The transmission is configured to transmit a movement and / or a force of the wedge clamp to the first movable pressure clamp such that the first movable pressure clamp can be moved effectively by means of the wedge clamp.

[0016] Advantageously, the transmission has at least one connecting rod. Thereby, it is easy to transmit a force to the first movable pressure clamp. In particular, the transmission has at least one further connecting rod, so that a movement can be transmitted to the first movable pressure clamp symmetrically.

[0017] Advantageously, the transmission has a contact geometry, which can be in operative connection with a guide runner of the wedge clamp, for example. In this regard, the contact geometry is connected with the connecting rod, for example, and is configured as a plain bearing, in particular, which can be engaged into the guide runner, so that a movement of the guide runner can be transmitted to the transmission. Thereby, a frictional loss of the contact geometry when moving in the guide runner can be minimized.

[0018] Alternatively, the contact geometry is configured as a simple sliding body or as a ball bearing or a linear bearing. These components have different properties, such as friction or force transmission, and can be replaced at low cost.

[0019] Preferably, a second drive device with a second drive is present for moving the first movable pressure jaws. By this, the first movable pressure jaws and the wedge jaws can be moved independently of one another, so that the active connection between the first movable pressure jaws and the wedge jaws can be adjusted by means of the first drive device or the second drive device.

[0020] Preferably, the wedge jaws have a guide section, wherein the guide section is arranged in the first guide device of the base structure. By this, the wedge jaws are arranged in a movable manner in the first guide device of the base structure when the wedge jaws are moved from the working position to the rest position in a positionally fixed manner. The wedge jaws are guided along the first guide device of the base structure.

[0021] Advantageously, the first guide device of the base structure is configured as at least one groove structure which extends in the longitudinal direction of the base structure, wherein the wedge jaws can be moved at least partially in a repeatable manner in the groove structure when the wedge jaws are moved from the working position to the rest position.

[0022] Preferably, the wedge jaws have a contact surface and a bottom surface, wherein a wedge angle of 0° to 30° is present between the contact surface and the bottom surface. In the working position of the wedge jaws, the contact surface is in active connection with the first movable pressure jaws and supports the first movable pressure jaws so that the first movable pressure jaws can be positioned in their crimping position in a non-movable manner. The bottom surface of the wedge jaws lies on the base structure of the crimping machine device so that the wedge jaws are held stable at least in the horizontal direction. The wedge angle between the contact surface and the bottom surface makes it possible to effectively adjust the crimping position of the first movable pressure jaws by only slightly adjusting the working position of the wedge jaws.

[0023] In particular, the wedge angle between the contact surface and the bottom surface is 1° to 10°, so that the positioning of the first movable pressure jaws can be adjusted even better and the wedge jaws can be held in position in a self-locking manner.

[0024] In the present application, the specific manner in which the wedge jaws can be held in position in a self-locking manner is that the flat wedge angle is chosen such that the friction coefficient of the contact surface between the first movable pressure jaws and the wedge jaws can assume a value so that the vertically acting counterforce of the first movable pressure jaws is no longer converted into a horizontal force, so that damage to the first drive device is avoided. The force transmission in the preferred direction (horizontal movement of the wedge jaws leads to a vertical movement of the first movable pressure jaws) is not affected to the greatest extent possible, so that it can continue to function.

[0025] Preferably, the wedge angle between the contact surface and the bottom surface is 5°, so that a reliable self-locking of the wedge jaws is made possible. Surprisingly, the positioning of the first movable pressure jaws can also be easily adjusted thereby, so that a particularly effective active connection between the wedge jaws and the first movable pressure jaws is present.

[0026] Preferably, the wedge clamp has a guide runner, wherein the guide runner has a first runner ramp. By this, the transmission device can be at least partially engaged into the first runner ramp and is guided in a positionally fixed manner.

[0027] In particular, the guide runner has at least one locking section for locking the transmission device. By this, the transmission device can be locked in a defined position.

[0028] Preferably, the guide runner has a first runner ramp and at least one further runner ramp. The wedge clamp with a guide runner having at least two runner ramps enables a particularly efficient movement of the transmission device. The first runner ramp of the guide runner causes a relatively small force to act on the first movable pressure jaw with a relatively large lifting movement. The at least one further runner ramp, which is in particular configured flatter than the first runner ramp, causes a larger force to act on the first movable pressure jaw with a smaller lifting movement. In this way, the dimensions of the first drive device can be set in a compact and cost-effective manner. The flat runner ramp acts in a self-locking manner on the movement of the first movable pressure jaw, so that it cannot be moved autonomously into the locked position.

[0029] Advantageously, the transmission device is at least partially engaged into the guide runner, so that the first movable pressure jaw can be moved in a positionally fixed manner. In this regard, at least one sliding bearing configured as a contact geometry can be guided in the guide runner, for example, so that the at least one connecting rod can move the first movable pressure jaw fixedly from its locked position into its pressure-connection position.

[0030] Preferably, the guide runner is configured to be at least partially open along at least one of the two runner ramps. The partially open guide runner has at least one guide runner opening, the opening boundary of which expands along the guide runner. In this way, frictional losses during the movement can be minimized.

[0031] Preferably, the guide runner is configured to be at least partially open along the flat runner ramp. Since the counterforce of the pressure connection machine or the first movable pressure jaw is mainly taken up by the contact surface of the wedge clamp, the transmission device is spared from strong forces during the pressure connection process.

[0032] Preferably, at least one of the two runner ramps is configured to be at least partially substantially parallel to the contact surface of the wedge clamp. By this, the transmission ratio between the movement of the first movable pressure jaw and the movement of the wedge clamp can be set in such a way that the active connection between the first movable pressure jaw and the wedge clamp can be adjusted particularly finely.

[0033] In particular, the first drive device has at least one locking element for moving the wedge jaw. The at least one locking element can improve the transition of the wedge jaw from its working position to its rest position, since the frictional losses during the transition can be further minimized. For example, the at least one locking element is arranged on the wedge jaw, so that such a minimization can be achieved directly on the wedge jaw and further dithering of the wedge jaw is minimized.

[0034] Preferably, a second guide device is present, wherein the first movable pressure jaw can be moved along the second guide device. Thereby, the first movable pressure jaw can be moved in a positionally determined manner when transitioning from the blocking position to the crimping position. This enables the first movable pressure jaw to be positioned in a repeatable manner.

[0035] Preferably, a prestressing element is present for prestressing the first movable pressure jaw. The prestressing element generates a return force of the first movable pressure jaw acting on the wedge jaw, so that a vibration-free active connection between the first movable pressure jaw and the wedge jaw can be generated, thereby generating a constant contact between the contact surface of the wedge jaw and the first movable pressure jaw. For example, the prestressing element is configured as a spring.

[0036] Advantageously, a protrusion is arranged on the first movable pressure jaw and a long hole is arranged on the second guide device, wherein the protrusion extends through the long hole and can be moved along the longitudinal extension of the long hole. Thereby, a constant return force can be exerted on the first movable pressure jaw.

[0037] The crimping machine according to the application comprises a crimping jaw device as described herein, wherein a further pressure jaw is present.

[0038] The crimping machine can establish several crimping connections, which can be established in a repeatable and high-precision manner in a repeated production cycle. The area between the first pressure jaw and the further pressure jaw is often referred to as the crimping area. As described above, the first movable pressure jaw is additionally spaced apart from the further pressure jaw in its blocking position, while the dimensions of the entire crimping machine can be set in a compact manner.

[0039] Advantageously, the further pressure jaw is arranged in a positionally fixed manner on the crimping machine. In this regard, the crimping process for establishing a crimping connection is completed when the first pressure jaw is transitioned from its blocking position to its crimping position, wherein at least one of the two pressure jaws has a crimping tool. In this way, the crimping connection can be established in a simple and time-saving manner.

[0040] Preferably, the further pressure jaw is movable. In this regard, the crimping process for establishing a crimp connection is accomplished by means of a crimping tool arranged on the further pressure jaw. The first pressure jaw is arranged in its crimping position, and the further pressure jaw is movable toward the first movable pressure jaw of the crimping jaw device in order to narrow the crimping area during the crimping process and to produce a crimp connection that can be established in a highly precise and reproducible manner. In this regard, the further pressure jaw is arranged on a crimping drive device having a crimping drive, which is configured in such a way that the further pressure jaw is shifted from its locking position to its crimping position in a reproducible manner.

[0041] In particular, the crimping drive device comprises an eccentric unit, which can be driven by the crimping drive and which causes a linear movement of the further pressure jaw. In this way, a simple, fast and space-saving drive for the further pressure jaw can be provided.

[0042] Preferably, the crimping machine and the crimping jaw device have a common base structure. In this way, the functional connection between the first pressure jaw and the wedge jaw supported by the base structure can be further enhanced in order to provide a stable crimping machine for a reproducible crimping process.

[0043] Preferably, at least one housing structure is present, on which the further pressure jaw is arranged and which can be connected to the base structure. In this way, the rigidity of the crimping machine can be further improved. The at least one housing structure ensures a rigid connection between the crimping jaw device and the further pressure jaw.

[0044] Advantageously, at least one guide device is present on the at least one housing structure, along which the further pressure jaw can be shifted from its locking position to its crimping position. By this means, the further pressure jaw can be guided in a positionally determined manner during the crimping process.

[0045] The method for establishing a crimp connection by means of a crimping machine according to the invention comprises the following steps:

[0046] a) shifting an anvil configured as a first movable pressure jaw from its locking position to its crimping position;

[0047] b) positioning a wedge jaw between the base structure and the first movable pressure jaw;

[0048] c) crimping into a crimp connection by means of a further pressure jaw, wherein at least one crimping tool is arranged on one of the two pressure jaws.

[0049] In the crimping position, the first movable pressure jaw is configured to establish a crimp connection in cooperation with the crimping tool on the further pressure jaw. In this regard, the first movable pressure jaw is stabilized and rigidified by the wedge jaw positioned between the base structure and the first movable pressure jaw, so that the crimp connection can be established several times in a reproducible and highly precise manner by means of the crimping jaw device in repeated establishment cycles.

[0050] In particular, the method is performed with the aid of a crimping tool device as described herein. The crimping tool device can be simply and stably arranged on a crimping machine and can also be arranged as an upgrade kit on an existing crimping machine.

[0051] Preferably, in step b) the wedge jaw is transferred from the rest position into the working position by means of a first drive. In this connection, the wedge jaw is brought into operative connection with the first movable pressure jaw in the working position, so that the first movable pressure jaw is stably supported.

[0052] Preferably, after step b) the first movable pressure jaw is transferred in the direction of the locking position, in order to ensure that the first pressure jaw is supported by the wedge jaw during the crimping in step c).

[0053] Advantageously, the first movable pressure jaw is transferred in the direction of the locking position by means of a second drive, in order to be able to transfer it in a positionally established and separately controllable manner.

[0054] Preferably, the first movable pressure jaw is transferred in the direction of the locking position by means of a prestress. The prestress causes a restoring force of the first movable pressure jaw acting on the wedge jaw, so that a vibration-free operative connection between the first movable pressure jaw and the wedge jaw exists, whereby constant contact between the contact surface of the wedge jaw and the first movable pressure jaw is maintained.

[0055] Preferably, the transfer of the first movable pressure jaw and the positioning of the wedge jaw in steps a) and b) are carried out simultaneously. In this connection, a transmission is arranged between the wedge jaw and the first pressure jaw, which transmits the power flow of the movement of the wedge jaw to the first movable pressure jaw, so that it can be easily transferred into the crimping position.

[0067] Figure 1 and Figure 2 A crimping tong device 15 is shown, which has a first movable crimping tong 20 and a first drive device 22 arranged on a base structure 17. The movable crimping tong 20 is arranged in a vertically movable manner on a second guide 25 when the crimping tong device 15 is arranged in a standby state on a base. The drive device 22 has a first drive 23 connected with a movable wedge tong 30. The wedge tong 30 has a guide runner 35 and can be transferred from a working position to a rest position by means of the first drive device 22, wherein the wedge tong 30 is in an active connection with the first movable crimping tong 20 in its working position and supports the first movable crimping tong 20 therefrom (see Figure 2 ). The first drive device 22, which is configured as a pneumatic drive device, is configured as a double-acting guide cylinder with an integral linear guide 28 and comprises a gas chamber as the first drive 23 and a piston rod 26 for linear movement or transfer of the wedge tong 30. The base structure 17 is a connection structure configured as a base plate and has a first guide 18 configured as a groove structure 19, which extends along the base structure 17 and in which a guide section 40 of the movable wedge tong 30 is arranged.

[0068] On the first movable pressure jaw 20 a protrusion 38 is arranged and on the second guide device 25 a long hole 39 is arranged. The protrusion 38 extends through the long hole 39 and is movable along the longitudinal extension of the long hole 39. In addition, a prestressing element 27 configured as a spring exists for prestressing the first movable pressure jaw 20, which is arranged on the second guide device 25 and is connected with the protrusion 38 of the first movable pressure jaw 20. The prestressing element 27 presses the first movable pressure jaw 20 onto the wedge jaw 30 in such a way that the active connection between the first movable pressure jaw 20 and the wedge jaw 30 is configured in a vibration-free manner, whereby a constant contact between the contact surface 31 of the wedge jaw 30 and the first movable pressure jaw 20 is maintained (see Figure 2 ).

[0069] The first movable pressure jaw 20 is connected with a transmission device 32 having a connecting rod 33. The connecting rod 33 is fixed to the first movable pressure jaw 20 by means of a fastening mechanism 21, which in this case comprises a screw and a centring sleeve (not visible in the figures). On the connecting rod 33 a plain bearing is arranged as a contact geometry 29, which engages into a guide slide 35 of the wedge jaw 30. The transmission device 32 is configured to transmit a movement and / or a force of the movable wedge jaw 30 to the first movable pressure jaw 20. In this connection, the wedge jaw 30 is driven by the first drive device 22 in such a way that the first movable pressure jaw 20 can be moved in the direction towards the crimping position and the wedge jaw 30 can be moved substantially orthogonally to the first movable pressure jaw 20 in the direction towards the working position. When the crimping jaw device 15 is in the standby state, the movement of the first movable pressure jaw 20 in the direction towards the crimping position is in the vertical direction. When the crimping jaw device 15 is in the standby state, the movement of the wedge jaw 30 in the direction towards the working position is in the horizontal direction. The wedge jaw 30 is positioned in its working position between the first movable pressure jaw 30 and the base structure 17, wherein the first movable pressure jaw 20 rests on the contact surface 31 of the wedge jaw 30 and is thus in its crimping position (see Figure 2 ). By this, not only the wedge jaw 30 is moved by the first drive device 22, but also the first movable pressure jaw 30 is transferred from the locked position to the crimping position.

[0070] Figure 3A wedge clamp 30 is shown having a contact face 31 and a bottom face 34. The contact face 31 is in operative connection with the first movable pressure clamp 20 in order to support it, for example, in the crimping position, when the wedge clamp 30 is in the working position. The bottom face 34 of the wedge clamp 30 is arranged in the groove structure 19 of the base structure 17 in order to stabilize the wedge clamp 30. A wedge angle β of 5° exists between the contact face 31 and the bottom face 34. The guide slide 35 of the wedge clamp 30 has a first slide ramp 36 and a further slide ramp 37. In this regard, the first slide ramp 36 is configured substantially more inclined than the further slide ramp 37, wherein the further slide ramp 37 is configured or extends parallel to the contact face 31. By this, the first slide ramp 36 causes a relatively large lifting movement (in the vertical direction) of the first movable pressure clamp 20, wherein a relatively small force acts on the first movable pressure clamp 20. The further slide ramp 37 causes a large force acting on the first movable pressure clamp 20 with a small lifting movement. The guide slide 35 has a guide slide opening 42, the opening boundary 43 of which is configured to open along the further slide ramp 37, which is configured flat, in order to shield the contact geometry 29 engaged into the guide slide 35 from the force during the crimping process. The wedge clamp 30 has a connection section 41, which is connected to the first drive 23.

[0071] Figure 4 A crimping clamp device 115 is shown, which is configured substantially similar to the crimping clamp device 15 described above. The crimping clamp device 115 differs from the crimping clamp device 15 according to Figures 1 to 3 in that a different wedge clamp 130 is present and the first movable pressure clamp 120 can be transferred from the blocking position to the crimping position by means of a second drive arrangement 150 and a second drive 151. By this, the first movable pressure clamp 120 can be moved independently of the movable wedge clamp 130. Accordingly, the wedge clamp 130 differs from the wedge clamp 30 according to Figures 1 to 3 in that the wedge clamp 130 does not have a guide slide and no transmission device is present. The wedge clamp 130 has a contact face 131, which supports the first movable pressure clamp 120 in its crimping position. The movable wedge clamp 130 is positioned between the base structure 17 and the first movable pressure clamp 120 in its working position in connection with the first drive arrangement 22. In addition, the wedge clamp 130 has a guide section 140 configured as a protrusion, by means of which the movable wedge clamp 130 is movably positioned in the groove structure 19. The wedge clamp 130 has a connection section 141, which is connected to the drive 23.

[0072] A crimping tool 16 is arranged on the first movable pressure clamp 120, which can also be positioned on the first movable pressure clamp 20 of the crimping clamp device 15 according to Figure 1 and Figure 2 .

[0073] Figure 5A crimping machine 200 is shown, which has a crimping jaw device 15 according to Figure 1 and Figure 2 and a wedge jaw 30 according to Figure 3 . The crimping machine 200 has a further crimping jaw 220, on which a crimping tool 216 is arranged. The further crimping jaw 220 is arranged on a crimping drive arrangement 222 with a crimping drive 223, which is configured to move the further crimping jaw 220 from its locking position into its crimping position. A crimping region 215 extends between the first movable crimping jaw 20 and the further crimping jaw 220, in which the cable and a connection piece, for example a plug, an eye or a socket, are positioned when establishing a crimping connection.

[0074] The base structure of the crimping machine 200 is identical to the base structure 17 of the crimping jaw device 15 described above. The crimping machine 200 has a housing structure 217, which is connected to the base structure 17. The housing structure 217 has a further guide arrangement 238, along which the further crimping jaw 220 can be moved from its locking position into its crimping position.

[0075] A method for establishing a crimping connection using the crimping jaw device 15 according to Figure 1 and Figure 2 , the wedge jaw 30 according to Figure 3 and the crimping machine 200 according to Figure 5 will now be described with reference to Figures 5 to 8 . Figure 6 A crimping jaw device 15 is shown, in which the wedge jaw 30 is in its rest position and the first movable crimping jaw 20 is in its locking position. Figure 7 A crimping jaw device 15 is shown, in which the wedge jaw 30 is between its rest position and its working position and the first movable crimping jaw 20 is between its locking position and its crimping position. Figure 8 A crimping jaw device 15 is shown, in which the wedge jaw 30 is in its working position and the first movable crimping jaw 20 is in its crimping position.

[0076] In a first step (step a)), the first movable crimping jaw 20 is moved from its locking position into its crimping position. The first movable crimping jaw 20 is connected to the wedge jaw 30 in that the connecting rod 33 engages into the guide slide 35 with its sliding bearing configured as a contact geometry 29 and the connecting rod 33 is fastened to the first movable crimping jaw 20 by means of the fastening mechanism 29. In this regard, the wedge jaw 30 is moved by means of the first drive 23 and the first drive arrangement 22 in the direction of the first movable crimping jaw 20. In this regard, the wedge jaw 30 is pressed in the direction of its working position from its rest position along the first guide arrangement 18. The contact geometry 29 slides along the first slide slope 36 of the guide slide 35, so that the first movable crimping jaw 20 is pressed in the direction of the further crimping jaw 220 by means of the transmission 32 when moving (seeFigure 7 ).

[0077] In a further step (step b) ) the wedge clamp 30 is positioned between the base structure 17 and the first movable pressure clamp 20. In this connection the wedge clamp 30 is brought into operative connection with the first movable pressure clamp 20 in that the contact surface 31 supports the first movable pressure clamp 20 and lifts the first movable pressure clamp 20 due to the wedge angle β between the contact surface 31 and the bottom surface 34 of the wedge clamp 30. By means of the first drive means 22 the wedge clamp 30 is transferred into the working position while the first movable pressure clamp is transferred towards the pressure connection position (see Fig. 2). Figure 8 ). In this connection the contact geometry 29, which is configured as a plain bearing, slides along a further slide ramp 37 of the guide slide 35, which is configured flatter than the first slide ramp, so that the first movable pressure clamp 20 is further pressed in the direction of the further pressure clamp 220 by means of the transmission 32 when being transferred. Subsequently or simultaneously the first movable pressure clamp 20 is transferred in the direction of the locking position by means of the prestressing element 27 (see Fig. 2) so that the first movable pressure clamp 20 ends up in the pressure connection position. For example, after positioning the cable and the connection configured as a socket in the pressure connection area 215, a pressure connection is subsequently made by means of the further pressure clamp 220, wherein at least one pressure tool 216 is arranged on one of the two pressure clamps 20 or 220 (step c) ). In this connection the further pressure clamp 220 is guided towards the first movable pressure clamp 20 by means of the pressure drive 151 so that the pressure tool 216 can establish the pressure connection.
