Description

[0001] The invention relates to a soldering device for soldering together stripped ends of two electrical cables by means of a solder connector.

[0002] DE 20 2021 002 636 U1 describes a soldering device for heat-shrink solder connectors in which two heatable plates are equipped with one or more indentations, matching in shape and length to the solder connector used, whereby these are attached opposite one another to a pliers device so that the indentations partially or completely enclose the solder connector when the pliers are closed.

[0003] The object of the invention is to provide a soldering device for soldering together stripped ends of two electrical wires by means of a solder connector, which is easy to use and produces a particularly reliable solder connection between two electrical wires.

[0004] The object is achieved by a soldering device for soldering together stripped ends of two electrical cables by means of a solder connector, comprising: - a first holding shell with a first partial receiving space for at least partially receiving a solder connector inserted into the partial receiving space, - a second holding shell which is adjustable relative to the first holding shell between an open position and a closed position and which has a second partial receiving space which complements the first partial receiving space of the first holding shell and which, in the closed position of the second holding shell, covers the solder connector inserted into the first partial receiving space, and - a first holder arranged on one axial end face of the first holding shell for fixing the one electrical line to the first holding shell in the open position of the second holding shell when the stripped end of this electrical line is inserted axially from one side into the solder connector which is inserted into the first partial receiving space, and - a second holder arranged on the other axial end face of the first holding shell for fixing the other electrical line to the first holding shell in the open position of the second holding shell when the stripped end of this electrical line is inserted axially from the other side into the solder connector which is inserted into the first partial receiving space.

[0005] A solder connector generally comprises a plastic sleeve in the form of a shrink tube. The sleeve can preferably be transparent so that the current position of a cable inserted into the sleeve can be seen. A ring of solder is inserted into the inside of a central section of the sleeve. A plastic sealing ring is inserted into the sleeve on the left and right sides of the central ring of solder at a respective distance from the ring of solder. Two ends of two electrical cables, which are to be connected both electrically and mechanically, are inserted into the sleeve of the solder connector from opposite sides. The insulation of the two ends of the two electrical cables is stripped at the ends. When inserted, the two ends of the two electrical cables abut one another end-on or lie next to one another overlapping, with the butt joint orthe overlapping area of ​​the two electrical cables should be positioned so that the joint or overlapping area is at the axial height of the solder ring. The respective plastic sealing ring should be at an axial height at which the respective associated electrical cable is no longer stripped. If the solder connector is heated sufficiently, the solder ring melts and, due to capillary forces, the liquid solder is drawn into the wire bundles of the two stripped ends of the electrical cables that are inserted butt-to-end or overlapping into the solder connector, thereby soldering the two stripped ends of the electrical cables together. This connects the two electrical cables both electrically and mechanically.To increase the durability of the connection, prevent moisture ingress, and / or provide additional mechanical reinforcement, each end section of each electrical wire is additionally connected to a respective sealing ring of the solder connector. To achieve this, the two sealing rings of the solder connector are also heated, causing the sealing rings, which are made of a thermoplastic material, to melt, shrink in their inner diameter, and bond to the respective insulating sheath of the associated electrical wire.

[0006] In addition to the long-established method of heating a solder connector using a separate hot-air gun, a clamp device has also been described that features heatable plates between which a solder connector and the opposite ends of two electrical wires can be clamped and soldered. However, the disadvantage of this method is that it is still uncomfortable to handle.For example, three hands are still required for safe handling. Not only does one hand have to hold the pliers, but when the pliers are open, a second hand must also be used to hold one electrical wire plugged into the solder connector to prevent one electrical wire from accidentally slipping out of the solder connector, and a third hand must be used to hold the other electrical wire plugged into the solder connector to prevent this other electrical wire from accidentally slipping out of the solder connector. However, if the two electrical wires are plugged into the solder connector when the pliers are closed, the correct position of the two ends of the two electrical wires relative to the solder connector can no longer be visually checked, which increases the risk of a faulty connection.

[0007] This is where the invention comes in. Its objective is to create a soldering device for soldering the stripped ends of two electrical wires together using a solder connector. This soldering device is easy to use and produces a particularly reliable soldered connection between two electrical wires. The soldering device according to the invention can be reliably handled by a single person using only two hands, allowing the positions of the electrical wires inserted into the solder connector to be adjusted particularly precisely, significantly reducing the risk of a faulty connection.

[0008] For this purpose, a generic soldering device has a first holder arranged on one axial end face of the first holding shell for fixing the one electrical line to the first holding shell in the open position of the second holding shell when the stripped end of this electrical line is inserted axially from one side into the solder connector which is inserted into the first partial receiving space, and a second holder arranged on the other axial end face of the first holding shell for fixing the other electrical line to the first holding shell in the open position of the second holding shell when the stripped end of this electrical line is inserted axially from the other side into the solder connector which is inserted into the first partial receiving space.

[0009] The first holder for securing one electrical wire to the first retaining shell, and the second holder for securing the other electrical wire to the first retaining shell, not only prevent the respective electrical wire from accidentally slipping out of the solder connector when the retaining shells of the soldering device are open, but thanks to the two holders, the solder connector itself is held in its position on the first retaining shell with a positive fit when the electrical wires are inserted into the solder connector on both sides. Thus, the two ends of the two electrical wires and the solder connector are already reliably secured to the soldering device before the soldering process begins, especially when the retaining shells are open.

[0010] The soldering device according to the invention can be handled in particular in the following way. With one hand, the first holder can be opened and with the other hand the first end of a first electrical line can be inserted into the pre-positioned solder connector and aligned therein. The first holder is then closed with the first hand so that the first electrical line is fixed in its correct position on the first holder and within the solder connector. The second holder is then opened in the same way with one hand and with the other hand the second end of a second electrical line can be inserted into the pre-positioned solder connector from the opposite side and aligned therein. The second holder is then closed with the first hand so that the second electrical line is also fixed in its correct position on the first holder and within the solder connector.In the state now achieved, the entire soldering device, particularly in the design of a manageable pliers tool, can be moved and / or operated with a single hand without the first electrical line and the second electrical line becoming detached from the soldering device or even slipping. The same applies to the solder connector itself, which is fixedly held to the soldering device by the two oppositely inserted ends of the two electrical lines. Neither the first electrical line nor the second electrical line nor the solder connector itself need to be held manually any longer. The first holding shell and the second holding shell can now be moved into the closed position with either one or two hands, as desired.

[0011] The first holder can have a first clamping lever which is adjustable between an open position in which the electrical line can be inserted into the first holder and a closed position in which the electrical line is fixed to the first holding shell, said first clamping lever being designed to clamp the electrical line between the first clamping lever and a first counter-hold connected to the first holding shell.

[0012] The first clamping lever can be pivotally mounted on the first holding part about a first rotation axis. The first clamping lever can have a clamping jaw lever arm associated with the first counter-holding element and an actuating lever arm with a first sensing section. The first sensing section can be designed to be pressed with the tip of a finger of a person's hand.

[0013] The first clamping lever can be pre-tensioned into its clamping position by means of a first spring.

[0014] By manually releasing the first clamping lever, the first holder can automatically return to its closed position.

[0015] The first holder can be mounted axially adjustable parallel or coaxially to the longitudinal extension of the solder connector.

[0016] By means of an axially adjustable mounting of the first holder, a first electrical cable fixed to the first holder can be automatically moved axially toward the second electrical cable positioned opposite. By automatically moving the first electrical cable toward the second electrical cable, the two electrical cables can be automatically positioned relative to each other, either in a butt joint or overlapping position.

[0017] The soldering device may optionally comprise a device for automatically axially adjusting the first holder towards the solder connector while moving the second holding shell against the first holding shell into the closed position.

[0018] On the one hand, the first electrical line can be manually adjusted axially during insertion into the soldering fixture or solder connector. On the other hand, this process can be performed automatically using the automatic axial adjustment device when the user closes the first holding shell and the second holding shell. This allows the closing of the soldering fixture and the axial adjustment of the first electrical line to be performed simultaneously.

[0019] The device for automatically axially adjusting the first holder towards the solder connector may comprise an adjustable first stop configured to limit the axial movement distance for the first holder.

[0020] By means of such a first stop, in particular the relative end position of the first electrical line with respect to the solder connector, in particular with respect to the relative position to the ring of solder, can be preset and / or the width of the overlap region of the first electrical line with the second electrical line can be preset.

[0021] The device for automatically axially adjusting the first holder towards the solder connector can comprise a first cone mounted on the first holding shell, which is guided axially adjustably in a corresponding first counter-shell wall of the first holding shell and a second counter-shell wall of the second holding shell, such that by moving the first holding shell and the second holding shell towards each other, the first cone is moved together with the first holder towards the solder connector.

[0022] The first cone can optionally be provided with a first radial slot through which an electrical cable can be inserted into the first cone in the radial direction.

[0023] The second holder may have a second clamping lever which is adjustable between an open position in which the electrical line can be inserted into the second holder and a closed position in which the electrical line is fixed to the first holding shell, said second clamping lever being designed to clamp the electrical line between the second clamping lever and a second counter-hold connected to the first holding shell.

[0024] The second clamping lever can be pivotably mounted on the first holding part about a second rotation axis. The second clamping lever can have a clamping jaw lever arm associated with the second counter-holding element and an actuating lever arm with a second sensing section. The second sensing section can be designed to be pressed with the tip of a finger of a person's hand.

[0025] The second clamping lever can be pre-tensioned into its clamping position by means of a second spring.

[0026] By manually releasing the second clamping lever, the second holder can automatically return to its closed position.

[0027] The second holder can be mounted axially adjustable parallel or coaxially to the longitudinal extension of the solder connector.

[0028] An axially adjustable mounting of the second holder allows a second electrical cable fixed to the second holder to be automatically moved axially toward the first electrical cable positioned opposite. By automatically moving the second electrical cable toward the first electrical cable, the two electrical cables can be automatically positioned relative to each other, either in a butt joint or overlapping position.

[0029] The soldering device may optionally comprise a device for automatically axially adjusting the second holder towards the solder connector while moving the second holding shell against the first holding shell into the closed position.

[0030] On the one hand, the second electrical wire can be manually adjusted axially while being inserted into the soldering fixture or solder connector. On the other hand, this process can be performed automatically using the automatic axial adjustment device when the user closes the first and second holding shells. This allows the closing of the soldering fixture and the axial adjustment of the second electrical wire to be performed simultaneously.

[0031] The device for automatically axially adjusting the second holder towards the solder connector may comprise an adjustable second stop configured to limit the axial movement distance for the second holder.

[0032] By means of such a second stop, in particular the relative end position of the second electrical line with respect to the solder connector, in particular with respect to the relative position to the ring of solder, can be preset and / or the width of the overlap region of the second electrical line with the first electrical line can be preset.

[0033] The device for automatically axially adjusting the second holder towards the solder connector can comprise a second cone mounted on the first holding shell, which is guided in an axially adjustable manner in a corresponding first counter-shell wall of the first holding shell and a second counter-shell wall of the second holding shell, such that by moving the first holding shell and the second holding shell towards one another, the second cone is moved together with the second holder towards the solder connector.

[0034] The second cone can optionally be provided with a second radial slot through which an electrical cable can be inserted into the second cone in the radial direction.

[0035] The first holding shell and / or the second holding shell can each be provided with at least one heating device, in particular an electric heating device.

[0036] The heating device can comprise at least one ceramic heating element. The respective heating device can be detachably inserted into the first holding shell and / or the second holding shell. The respective heating device can be replaceable in this respect. The heating device can thus form a heating insert. The heating insert can have an inner contour that is adapted to the shape of a type of solder connector. Thus, a larger solder connector can be used in combination with a first heating insert that has a larger inner contour adapted to the larger solder connector. Conversely, a smaller solder connector can be used in combination with a second heating insert that has a smaller inner contour adapted to the smaller solder connector. Thus, the soldering device can be used for different types of solder connectors by exchanging the detachable heating devices.

[0037] The heating device, in particular the respective heating insert, can be provided with a coating on an inner casing wall against which the respective solder connector rests in its inserted state, which prevents the solder connector from sticking to the inner casing wall. The coating can be, for example, a coating made of polytetrafluoroethylene (PTFE).

[0038] Alternatively or in addition to a coating preventing adhesion, a mechanical ejector can be provided on the first holding shell and / or on the second holding shell or on the respective heating insert, which is designed such that when the ejector is actuated manually or semi-automatically by opening the pliers head halves, which causes the ejector mechanically coupled to the pliers head halves to be activated, the existing solder connector is pushed out and / or ejected by the ejector.

[0039] The at least one heating device can comprise an electrical circuit with at least one switching means, wherein the circuit and the switching means are designed and configured to switch the heating device off in an open position of the first holding shell and the second holding shell and to switch it on in at least one closed position of the first holding shell and the second holding shell.

[0040] For this purpose, the switching means can be arranged on the first holding shell or the second holding shell and monitor the current position of the first holding shell and / or the second holding shell.

[0041] The soldering device can have a first heating device designed to generate a temperature that exceeds the melting temperature of the solder of the solder connector in an axially central section of the first holding shell and the second holding shell, and the soldering device can have at least one second heating device designed to generate a temperature that exceeds the shrinkage temperature of the plastic sleeve of the solder connector, but falls below the melting temperature of the solder of the solder connector in at least one axially lateral section of the first holding shell and the second holding shell, wherein the circuit and the switching means are designed and configured to switch on the first heating device in a first closed position of the first holding shell and the second holding shell and to leave the at least one second heating device switched off.and to switch on the at least one second heating device only in a second closed position of the first holding shell and the second holding shell, in which the first holding shell and the second holding shell are even further closed compared to the first closed position.

[0042] The first holding shell can be designed as a first insert which is adapted to the size of a size type of solder connector and is releasably inserted in a first tool half of the soldering device and / or the second holding shell can be designed as a second insert which is adapted to the size of a size type of solder connector and is releasably inserted in a second tool half of the soldering device.

[0043] The first retaining shell and / or the second retaining shell can have an inner contour that is adapted to the shape of a type of solder connector. Thus, a larger solder connector can be used in combination with a first retaining shell and / or a second retaining shell, which has a larger inner contour adapted to the larger solder connector. Conversely, a smaller solder connector can be used in combination with a different first retaining shell and / or a different second retaining shell, which has a smaller inner contour adapted to the smaller solder connector. Thus, the soldering device can be used for different types of solder connectors by exchanging the detachable first retaining shell and / or second retaining shell.

[0044] The soldering device can be designed as a manageable pliers tool in which the first holding shell is provided on one pliers head half and the second holding shell is provided on the other pliers head half.

[0045] The first pliers head half can be coupled to a first handle portion, and the second pliers head half can be coupled to a second handle portion. By manually pressing the first handle portion and the second handle portion together, the first pliers head half and the second pliers head half can be manually moved into the closed position.

[0046] As an alternative to being designed as a manageable pliers tool, the soldering device can also be designed as a stationary pressing tool, in which the first holding shell is provided on a stationary counter-hold of the pressing tool and the second holding shell is provided on a movable punch of the pressing tool that is adjustably mounted relative to the counter-hold.
