This application is a continuation of prior co-pending International Application No. PCT/IB2009/053451 filed Aug. 6, 2009, designating the United States, which claims the benefit of European Patent Convention Application No. EP 0814168.2, filed on Aug. 8, 2008, the substance of which is incorporated herein by reference.
FIELD OF THE INVENTIONThe present disclosure relates to a cable package with a package container that serves for accommodating a cable to be packaged and is at least sectionally realized in a dimensionally stable fashion. The present disclosure also relates to a method for installing a cable end on a connector such as a plug, a power supply unit and the like with the aid of such a cable package.
BACKGROUND OF THE INVENTIONThe automated processing of cables is still difficult and until now only realized to a limited degree with justifiable costs. It is particularly difficult to take hold of and exactly position flexible cables such as, for example, electric power cables with the grippers of a manipulating device, especially if the corresponding cable is delivered in the form of bulk material and more or less entangled.
In the manufacture of electric appliances, charging components or the like that are equipped with a permanently attached power cable or of plug-in power supply units that feature a permanently attached cable for being connected to an end device, a large portion of the power cable installation needs to be carried out manually. This applies, in particular, to the delivery of the power cable to a desired automated installation on the device. Since a power cable is a flexible part, an economical automated delivery could not be realized in the desired fashion until now if the cable is supplied in the form of bulk material. In this state, the cable ends or power plugs and cable ends are not defined and can only be taken hold of with a very high technical expenditure. This is the reason why the power cable delivery was usually carried out manually until now.
According to one known proposal for automating the cable installation, a power cable is manufactured immediately before the installation. In this case, the cable is delivered to the power cable manufacture from a roll and cut to the required length, wherein the power plug is subsequently attached and the cable is then connected to the device. Due to this special manufacturing sequence, both cable ends are always in a defined position. However, this method is not suitable for instances, in which a corresponding cable in the form of a prefabricated accessory part is additionally processed, for example, in the small electric appliance industry that does not have a separate cable manufacture at its disposal.
It is desirable to develop an improved cable package and an improved method for to installing a cable end of the initially cited type, of eliminating the disadvantages of the state of the art and of additionally developing the latter in an advantageous fashion. Accordingly, there is a need for the automated handling of the cable to be processed such that the cable end can be exactly positioned and installed in a largely automated fashion on a connector such as a plug, a power supply unit, a charging device and the like.
SUMMARY OF THE INVENTIONAccording to one embodiment, a cable package is provided. The package includes a package container for accommodating a cable wherein the package container is sectionally realized in a dimensionally stable fashion; and holding means for holding a cable end and/or a connector connected to the cable end in a cable processing position, wherein the holding means are provided on a wall of the package container.
While the specification concludes with claims which particularly point out and distinctly claim the subject matter that is regarded as the invention, it is believed the various embodiments will be better understood from the following description taken in conjunction with the accompanying drawings, in which:
The figures herein are not necessarily drawn to scale.
DETAILED DESCRIPTION OF THE INVENTIONAccording to the present disclosure, a cable package is included for positioning the cable end to be processed and to suitably design the package for this purpose such that it is not only possible to easily take hold of and precisely position the package, but also to place the to cable into a defined position relative to the package container that is at least sectionally realized in a dimensionally stable fashion for this purpose. As described herein, the cable package is characterized in that holding means for holding a cable end and/or a connector connected to the cable end in a cable processing position are provided on a wall of the package container that is at least sectionally realized in a dimensionally stable fashion. This makes it possible to move the cable end or a connector installed thereon into a defined position, for example, relative to an installation head or probe by correspondingly positioning the cable package that can be taken hold of in a much simpler and more precise fashion than a cable of undefined flexibility. According to this embodiment, the cable end can be connected to said connector, preparations of the cable required for producing this connection can be carried out or the finished connection between the cable and the connector can be checked.
The cable fixed on the package container may be prepared, in particular, for being contacted with the terminals of a connector and subsequently installed on the connector. The preparations carried out prior to the actual installation of the connector may comprise, for example, splicing of the stranded conductors of an electric cable, stripping the insulation, bending the individual stranded conductors into the respective installation position, crimping the cable, i.e., attaching a crimp-type connector, soldering the cable conductors, contact-bonding the line connections and/or casting the cable end in an insulation.
Depending on the type of connector to be installed, other preparatory steps can be carried out while the cable is advantageously arranged in the package container and held on a wall or in the vicinity of a wall with its cable end such that the cable end can be positioned by positioning the package container. The package container with the cable ends held thereon is not only advantageous for the actual installation of a connector, but also for subsequent testing steps. For example, a functional test that is usually carried out as part of the final installation can be simplified with the package container. The connector that is installed on the cable end and consists, for example, of a plug, can be connected to an electric test circuit in order to check the electric conductivity while the cable is arranged in the package container and the cable end or the connector installed thereon is held in an exactly defined position on the package container by the holding means.
Functional elements arranged in other sections of the cable may be alternatively or additionally checked. For example, switches and/or measuring points on a cable section accommodated in the package container can be delivered to a test station. For this purpose, to the package container may comprise other holding means that fix the cable and/or the functional component installed thereon such as, for example, the aforementioned switch in a defined position relative to the package container.
Since the flexible cable is arranged in a cable package of the above-described type, it can be cost-efficiently handled automatically in a production line with simple manipulating means such as, for example, the gripping instrument of a manipulator. Furthermore, the installed and finished cable is advantageously arranged in a package that can also be automatically handled in a secondary packaging line. Small appliances such as, for example, power supply units, switches, line filters and the like can also be packaged with two outgoing cables or plugs, on which switching processes, measurements and the like can be automatically carried out through corresponding recesses in the package container. The positions of switches and measuring points are defined by the package container in this constellation. In contrast to loose cables, the package also makes it possible to automatically identify the cable and/or a device installed thereon based on relevant information such as, for example, batch numbers, test results or material numbers.
In another embodiment, the cable package is characterized in that the wall, on which the aforementioned holding means are provided, and/or another wall of the package container features a cable through-opening such that the cable can extend through the wall and, in particular, from an inner side of the package container to an outer side. In this case, the holding means are advantageously realized in such a way that the cable end and/or the connector connected thereto is positioned on an outer side of the package container. This makes it possible to also carry out the cable installation, testing and/or processing while the package container is closed and to simply gain access to the cable and/or the connector installed thereon from an outer side. It would also be possible, in principle, to hold the cable end in a predefined position on an inner side of the package container with the aforementioned holding means and to carry out the above-described installation, testing and processing steps in the interior of the package container. However, the arrangement of the processing position on an outer side of the package container such that the cable extends through the wall makes it easier to gain access with corresponding installation tools. Additionally, the package does not have to be opened in order to process the cable, i.e., the processing can be carried out while the package remains closed such that the attachment of the package can be separated from the additional processing and the cable can be transported between these steps in a particularly to simple fashion.
The aforementioned cable through-opening may, in principle, be realized in different ways, for example, in the form of a bore. According to another embodiment, however, the cable through-opening advantageously forms a clamping groove that is open toward one side of the respective wall and into which the cable to be positioned can be simply inserted transverse to its longitudinal direction. This eliminates threading of the cable that may be quite cumbersome depending on the size of the through-opening and also significantly simplifies the attachment of the package.
The holding means may be arranged, in principle, at a distance from the aforementioned through-openings, but are preferably provided at least in the vicinity of said through-opening. In one particularly advantageous additional development of the invention, the holding means are integrated into the aforementioned through-opening or are formed by this through-opening, respectively.
The holding means may be designed in different ways. In order to ensure that the cable is held in a stable fashion and the package can be easily attached, it would be possible to provide form-fitting holding means, in one example, in the form of elastic clips and/or snap-in means, into which the cable and/or the connector installed thereon can be respectively clipped or snapped. In another embodiment, the holding means are realized in a clamping fashion and feature corresponding clamping means, in one example, in the form of a clamping groove for clamping the cable in the respective cable processing position. In an additional development of the invention, said clamping groove may form part of the aforementioned cable through-opening that, in turn, at least sectionally forms a laterally tapered clamping slot, into which the cable to be positioned merely needs to be inserted transverse to its longitudinal direction in order to be clamped and held in position. At its base, the clear width of said clamping groove is, in one example, adapted to the cable diameter in such a way that a cable sheath is held in position with a press fit and cannot slip or pull out, namely while simultaneously preventing damages thereto.
Depending on the processing steps to be carried out on the cable, the cable end or the connector installed thereon may be held in different alignments relative to the package container. In one embodiment, the cable end is positioned such that it protrudes from the wall, particularly held such that it projects from the wall of the package container substantially perpendicularly. In this case, the processing position may be chosen such that the cable end or to the connector installed thereon is exposed on all sides and spaced apart from other container walls in order to freely access the cable end from all sides.
According to one embodiment, the cable end can be pulled out of the package container by a certain distance prior to or during the installation of the connector or the preparation of the cable for this installation in order to simplify the processing of the cable end. This may be realized, for example, by pulling out the cable end that slides through the holding means by a certain distance while the package container is held by the holding device. Alternatively or additionally, the package container may feature two parts that can be moved relative to one another, such that they are displaceably guided on one another, wherein the cable end can be pulled out by the aforementioned distance by displacing the two parts relative to one another and, after the installation of the connector, reinserted together with the installed connector by displacing the container parts back into their original position.
In one embodiment, simple storage and simple transport of the pre-configured cables may be achieved by providing that the package container is stackable. To this end, the package container may feature at least one plane stacking surface that is positioned and arranged such that it can be securely placed on another identically designed package container. The package container has, in particular, an essentially plane bottom that may, if applicable, feature projecting leg areas in order to also securely stand on uneven surfaces and to achieve the removal from a completely smooth surface without suction.
In one embodiment, the package container may be cube shaped, wherein the package container includes a trough-shaped base body that features the holding means and/or the through-opening for the cable end or the connector installed thereon on one of its side walls, and wherein said side wall consists of a face wall that adjoins the bottom of the package container.
In another embodiment, the trough-shaped base body may form an inner body of the package container that is displaceably accommodated in an outer body that, in one example, is also cube shaped similar to a matchbox, wherein the outer body is realized open on the side, on which the cable end is held on the inner body, so as to be able to take hold of and, if applicable, pull out the cable end by a certain distance. The latter can be achieved by or during a displacement of the inner body relative to the outer body.
In order to prevent the projecting cable ends or projecting connectors from interfering to with the stacking of the cable packages, one embodiment has a wall, on the outer side of which the cable end or the connector installed thereon is held in the aforementioned cable processing position. The wall with the cable positioned on the outer side thereof is set back relative to the other adjoining walls of the package container such that the cable end or the connector projecting from the wall is practically concealed under the cover formed by the other protruding container walls. The wall with the cable positioned on the outer side thereof may, in particular, be set back relative to the adjoining container walls in such a way that said walls define a cable receptacle recess, in which the cable end and/or the connector installed thereon can be positioned.
In one embodiment, the cable receptacle recess is open and/or only partially closed toward at least one side and the cable end lying in the cable receptacle recess remains visible and, in one example, also accessible. If a displaceable inner body is provided, the outer body of the package container may be longer than the inner body such that the corresponding projection of the outer body defines the aforementioned receptacle recess.
In another embodiment, the package container may be a folding box. Alternatively, the package container may be a dimensionally stable moulded plastic part. For example, the package container may consist of a deep-drawn part, an injection-moulded part or even a moulded EPS part. The design in the form of a moulded plastic part provides the advantage of making it possible to realize more or less arbitrarily shaped package contours. It is also easily possible, in particular, to integrally mould special gripper contact surfaces, for example, in the form of depressions or projections such that the cable package can be taken hold of accurately with respect to reference points.
