Description

METHOD AND TOOL FOR SEPARATING AND JOINING A CONTACT WITH A CABLE FIELD OF INVENTION The invention relates to a method and a tool for separating and joining a contact with a line that has high shielding. BACKGROUND OF THE INVENTION Document DE 20 2017 003 670 U1 relates to a device for crimping at least one wire of a cable. The document describes a cable with a shield whose end is raised. In the publication, a device for crimping at least one wire may have what is known as a cutter for separating individual crimp contacts from a support strip. During cable assembly, the cable is stripped towards the end, and its wire is stripped at one end. Furthermore, the shield is configured to protrude radially outwards. During operation of the device, the cable, prepared in this way, is first inserted into a recess in a support, against one direction, then inserted into an opening of the cutter, and finally placed onto a support surface.For the actual crimping, the crimping tool moves in a z-direction along a predefined path relative to an anvil, from a rest position to a processing or crimping position. During this process, the crimping lugs are plastically deformed to create a tight seal around the cable. The publication also describes the cutter as having an opening into which the cable, which has the shielding and whose end is configured, can be inserted so that the configured shielding is positioned within the cutter opening. In the prior art, there is at least one disadvantage: the cable with the raised shield can no longer be moved freely along its longitudinal direction, particularly not in the direction of contact, after the shield has been placed in the cutter opening. As a result, further movement of the cable along its longitudinal direction is not possible, for example, to perform an additional splicing step. SUMMARY OF THE INVENTION Therefore, an objective of the present invention is to provide a device and a method with which a line with high shielding can be flexibly processed. The above objective is achieved by means of a separation and joining method according to claim 1, as well as a tool for separating and joining a contact with a line of ML / a / ZUZZ / UUU l Oü in accordance with claim 9. Other advantageous embodiments of the invention can be found in the dependent claims, the description and the drawings. In particular, the aforementioned objective is achieved by means of a separation and joining method for a first contact with a line that has high shielding. The method has the following steps: moving an actuator and a clamp from an open position to a closed position, so that the actuator acts on a cutter and the first contact, which may be provided on a contact support strip, can be separated from the contact support strip and the first contact can be fixed with the clamp; inserting the line into the first contact until the high shielding of the line is in contact with the actuator and / or cutter; activating a first cylinder, so that a stop moves from an inactive position to an active position, where the first contact can be fixed in the active position by the stop; moving the actuator and clamp from the closed position to the open position, and simultaneously activating a second cylinder.so that a contact guide strip and the cutter move from an initial position to a lowered position, and joining the cable to a final position at the first contact. The method allows for the continuous separation of a first contact from a contact support strip and the joining of a line to the separated contact in a single process cycle. Specifically, the method allows for the separation of an outer conductor contact and its joining to a line that has a fixed inner conductor contact and an erected shield. Joining a cable with the shield configured on an outer contact requires that the cable or inner contact be inserted deeply into the outer contact. The line must be inserted deeply into the outer conductor contact along its longitudinal direction to correctly position the line with the inner conductor contact on the outer conductor contact. If the joining is to take place directly in the cutter of a crimping tool, the line must be movable along its longitudinal axis.Using the method described here, the cable with the configured shielding can be fully joined directly in the cutter up to its final position at the first contact or contact of the outer conductor, since the cable can be moved freely with the shielding in place. This process simplifies cable assembly. Preferably, the step of moving the actuator and the clamp between the open and closed positions comprises a movement in a first direction, in particular transverse to the longitudinal direction of the line. This movement has the advantage of allowing for a directed force effect from the actuator to the cutter. Specifically, a clean separation between the contact and the contact support strip is possible with a vertical movement, without unwanted deformation. Furthermore, the fastener's locking mechanism provides a force-locking effect at the first contact point, ensuring a reliable connection. The step of moving the stop between the active and inactive positions preferably includes a movement in a second direction, particularly along the longitudinal direction of the cable. This movement allows the first contact to be secured independently of the clamp's position or movement. Specifically, the movement occurs on the side of the first contact furthest from the cable. In this way, the movement does not reduce the cable's range of motion. Finally, as a result of this movement, a form-fitting fixation of the first contact can be achieved through the stop or the opening in the stop. Activating the first and / or second cylinder preferably includes extending the first and / or second cylinder. The movement of the actuator and the fastener is preferably performed in a split cycle of a crimping tool. A crimping tool known in principle from the prior art can be used for this method. This simplifies its application. However, the full force of the tool is not required. ML / a / ZUZZ / UUU l Oü crimping, as required for crimping, to separate and join the first contact, so that it is more careful with the material to perform only the movements in a split cycle, applying only a fraction of the maximum force of the crimping tool to the first contact. The preferred method also includes the step of retracting the first cylinder so that the stop moves from the active to the inactive position, releasing the first contact. Retraction allows the first contact, into which the wire was inserted, to move freely again and be removed from the tool. Additionally, the stop returns to its initial position for a new process cycle. The method preferably also includes the step: Retracting the second cylinder allows the contact guide strip and cutter to move from the lowered position to the initial position. Retracting or raising the contact guide strip enables a new first contact to be placed on the anvil as it passes through the contact guide strip. The contact guide strip and cutter then return to their basic position for a new process cycle. The preferred method also includes the step of retracting the second cylinder so that the contact guide strip and cutter move from the lowered position to the initial position. Returning or raising the contact guide strip allows a new first contact to be repositioned on the anvil as it passes over the contact guide strip. Furthermore, the contact guide strip and cutter return to their basic position for a new process cycle. Preferably, the method also includes the step of retracting the second cylinder, so that the contact guide strip and cutter move from the lowered position to the initial position. Retracting or raising the contact guide strip allows a new first contact to be repositioned on the anvil as it passes over the contact guide strip. Furthermore, the contact guide strip and cutter return to their basic position for a new process cycle. The preferred method also includes the step of retracting and extending a third cylinder coupled to a feeder. This allows the contact support strip to be moved a predetermined distance in the process direction with the aid of the feeder, thus providing the first subsequent contact on the cutter. This step enables a new process cycle to begin. The use of a third cylinder, which is identical in construction to the first and / or second cylinder, allows all three cylinders to respond and activate in a timely manner, as their behavior is the same, enabling a synchronous process cycle. The above objective is also achieved in particular by means of a tool for separating and joining a first contact, which is provided on a contact support strip, with a line having a raised shield, having a contact guide strip to provide first contacts to the contact support strip, a cutter to separate a first contact from the contact support strip, a fastener to fix the first contact, a first cylinder having a stop, wherein the cylinder can move the stop from an inactive position to an active position and the stop can fix the first contact in the active position, and a second cylinder coupled to the contact guide strip and the cutter, wherein the second cylinder can move the contact guide strip and the cutter from an initial position to a lowered position. The tool enables the processing of cables with high shielding. Thanks to the cylinder, particularly the first and second cylinders, components can be moved within the tool without interfering with the line's movement. This increased freedom of movement allows process steps, especially within a process cycle, to be performed on the tool that were not possible with prior art tools. The first contact preferably comprises an outer conductor contact, and a second contact, in particular an inner conductor contact, is preferably attached to the line. Processing outer conductor contacts, and in particular joining lines with an inner conductor contact and high shielding on an outer conductor contact, requires deep insertion or positioning of the cable into the outer conductor contact. For deep positioning, the line must have at least full freedom of movement along its longitudinal axis. This freedom of movement is possible or provided by the present tool. The contact guide strip is preferably coupled to the cutter via an actuator. Coupling the cutter to the contact guide strip via an actuator allows for precise adjustment of the cutter's movement relative to the guide strip. For example, the transport height can be adjusted relative to the cutter's height in its base position. The fastener primarily secures the first contact point using spring tension. This spring tension allows the fastener's clamping force to be adjusted. If unexpectedly high forces suddenly appear in the direction of the first contact point, the fastener can compensate for them using the spring tension. When the tool moves, the spring tension ensures reliable contact between the fastener and the first contact point. The tool preferably comprises a crimping tool. A crimping tool is suitable for cable assembly. In particular, a crimping tool is configured to separate a contact from a contact backing strip and to exert forces on the separated contact. The forces can only be the holding forces required for joining. The use or conversion of a tool that is already known makes it easier to use or adapt. The tool preferably also has a third cylinder coupled to a feeder, where the third cylinder can move the feed in a process direction, so that the contact support strip can be moved in the process direction with the aid of the feeder. The third cylinder is preferably of identical construction to the first and / or second cylinder, so that the behavior of the cylinders is the same. Structurally identical cylinders facilitate or enable the synchronous execution of a process.

It shows: Figure 1 is a perspective view of one modality of a tool; Figure 2 shows a side view of a section of the tool from Figure 1 in an initial position; Figure 3 shows a perspective view of a section of the tool, where a line with the shielding installed in a first contact has been partially inserted; Figure 4 shows a side view of the illustration in Figure 3; Figure 5 shows a perspective view of a section of the tool, where a line with the shield installed in a first contact has been fully inserted; Figure 6 shows a side view of the representation of Figure 5; and Figure 7 shows a side view of a section of the tool from Figure 1 in a final position. DETAILED DESCRIPTION OF THE INVENTION The exemplary modalities are described in detail below with reference to the figures. Figure 1 shows an exemplary embodiment of a tool 1. The tool 1 is preferably a crimping tool for separating and crimping contacts in a line. The tool 1 is configured to provide a contact support strip 13, to which contacts 11 are attached, in a process direction X with the aid of a feeder 62 in a processing area. At least one contact 11 can be separated from the contact support strip 13 in the processing area. In the exemplary embodiment shown, a contact 11 is separated from the contact support strip 13 by means of a cutter 30. A contact 11, preferably located on an anvil 38 in the processing area, is separated from the contact support strip 13 by a shearing motion between the anvil 38 and the cutter 30. To move the cutter 30 relative to the anvil 38, i.e., to actuate the cutter 30, an actuator 20 exerts a force on the cutter 30 in the exemplary embodiment. To do this, the actuator 20 moves from its initial or open position (see Figure 1), which is separate from the cutter 30, toward the cutter 30 or to a closed position (see Figure 3). With a continuous movement of the actuator 20, it presses the support surfaces 34 on the cutter 30 and moves it relative to the anvil 38.The movement of the actuator 20 and the cutter 30 is preferably transverse, in particular perpendicular, to the longitudinal direction X of the contact support strip 13. A first height H1 of the cutter 30 relative to the anvil 38 or a lower shielding guide 36 decreases to a second height H2. The contact support strip guide 32 or the bearing surfaces 34 can serve as reference points on the cutter 30 to determine the height. The force of the actuator 20 on the cutter 30 preferably occurs during a split cycle of the crimping tool 1, so that only the force required for cutting acts on the cutter 30. In the closed position, with the actuator 20 in contact with the cutter 30, there is preferably an upper shielding guide 22, mounted on the actuator 20, and a lower shielding guide 36 mounted on the tool 1. Preferably, a line guide is formed on the contact surface of the cutter 30, in which a line 10 is present even when the actuator 20 and the cutter 30 are in contact with each other. Line 10 is preferably a multilayer line, specifically one with an inner conductor. In the embodiment shown, an inner conductor contact 12 is already attached to the inner conductor. At least one braided shield 14 surrounds the inner conductor. The braided shield is bent away from line 10, i.e., installed. A gap can be created between the raised shield and the inner conductor contact along the longitudinal Y direction of line 10. Preferably, the braided shield 14 is bent 90 degrees away from line 10. This bend increases the outer diameter of line 10 in the area of ​​the bent braided shield 14 (see Figure 2). In the state where the actuator 20 is in contact with the cutter 30, although the inner conductor contact 12 can extend through the line routing mentioned above in the cutter 30, nevertheless, line 10 as a whole can only be inserted so far into the cutter 30 until the raised braided shield 14 abuts the actuator 20 and / or the cutter 30 (see Figures 3 and 4). In this position, line 10 or the inner conductor contact 12 is only partially, and not completely, disposed of in the outer conductor contact 11. The external conductor contact 11 is an exemplary embodiment of a first contact to be added to line 10. In the exemplary embodiment shown, the external conductor contact 11 is fixed to the anvil 38 by means of a clamp 24. In the open position, the crimping tool opens to its maximum, so that the distance between the anvil and the clamp can have a maximum travel of approximately 40 mm. The clamp 24 preferably moves simultaneously and in parallel with the actuator 20. For clamping, the clamp 24 touches the external conductor contact 11 in the position when the actuator 20 comes into contact with the cutter 30. The clamp 24 is preferably spring-mounted. When the actuator 20 moves further to actuate the cutter 30, the clamp 24 exerts a compressive force on the first contact or external conductor contact 11 and thus fixes the contact 11 to the anvil 38 (see Figure 4).The clamp acts transversely, specifically perpendicularly, to the contact of the outer conductor 11 or the longitudinal Y direction of line 10. The clamp is secured by a forced closure. Due to the spring, a reduced force is applied to the contact of the outer conductor 11, preventing damage. This clamp allows, among other things, consistent accuracy when separating the contacts 11 from the contact support strip 13. To lock the external conductor contact 11 in position when the retainer 24 is withdrawn, a stop 42 is moved from an inactive position P1 to an active position P2. This movement is effected by a first cylinder 40 that can be extended and retracted in one direction. The direction is preferably along the longitudinal Y-axis of line 10 or of the external conductor contact 11. In the exemplary embodiment shown, the stop 42 has an opening 44 configured to accommodate either the first contact or the external conductor contact 11. The stop 42 is pushed with the opening 44 onto the external conductor contact 11 (see Figures 2 and 4). The external conductor contact 11 is locked in place by the stop 42. The first cylinder 40 can be pneumatically operated. Figure 5 shows tool 1 in a later state. To fully insert line 10 or inner conductor contact 12 into the first or outer conductor contact 11, the actuator 20 and the clamp 24 return to their initial or open position, i.e., separated from the cutter 30 and the anvil 38. The first or outer conductor contact 11 is also held in place by the stop 42. Due to the partial connection at the outer conductor contact 11, line 10 is already correctly aligned with the outer conductor contact 11. The conduit 10 can be held in position by a clamp such as a clamp (not shown). The cutter 30 is lowered to a third height H3 so that the raised portion of the braided shield 14 in contact with the cutter 30 is no longer blocked by the cutter 30 in the longitudinal direction Y of line 10. For this descent, a second cylinder 50, coupled to the contact guide 52, extends by a gap height S (see Figure 5). As a result, the contact guide strip 52 descends from a first distance difference DI to a second distance difference D2. This difference can be equal to the height of the gap S compared to the lower shield guide 36, which is firmly connected to tool 1. In one example, the contact guide track 52 is coupled to the cutter 30 by a drive. The drive can be implemented as a bolt or screw connection, for example.The descent of the contact guide strip 52 causes the cutter 30 to also descend to the third height H3 relative to the lower screen guide 36. As shown in Figure 5, the retraction of the actuator 20 and the clamp 24, and the simultaneous descent of the cutter 30, results in line 10 no longer being obstructed along its longitudinal Y-axis by the braided shield 14. In this position of tool 1, line 10, and in particular the internal conductive contact 12, can be fully inserted into the first contact or the external conductive contact 11 (see Figure 6). Figure 6 shows a final position of tool 1, in which line 10 with the attached external conductor contact 11 has been removed from tool 1. The connection only involves arranging line 10 or the internal conductor contact 12, which is connected to line 10, onto the external conductor contact 11. The external conductor contact 11 can be connected to line 10 in a separate, subsequent process step. In the final position, the cutter 30 returns to its initial height H1. To achieve this, the second cylinder 50 is retracted, thereby moving the contact guide strip 52, and preferably also the cutter 30 via the actuator, from the lowered position to the basic position. In another step of the process, a third cylinder 60 can move in and out along a process direction X (see Figure 1). The third cylinder 60 is coupled to a feeder 62 in the illustrated manner, so that the movements of the third cylinder 60 move the feeder 62 accordingly, thereby advancing the contact support strip 13 a certain length in the process direction X, so that another contact 11, or external conducting contact, is placed on the anvil 38. A new process cycle can then begin.
