Description

Cable Cradle

The present invention relates to a cable receiving device with a longitudinally extending receiving body having at least two ends, which contains at least one cable channel for receiving one or more cables or lines, in particular for a domestic appliance.

Cable receiving devices are used in devices and in particular in household appliances for safe and flexible cable or cable routing. It should be noted that here the terms cables and lines are used as synonyms and for individual cables and also for the majority thereof. Incidentally, cables are not only electrical cables or lines, but also other cables or lines, such as optical, pneumatic, hydraulic and / or mechanical cables or lines, such as cables. Ropes. Such different cables or lines can be accommodated either only with similar or with different types of cables or lines of one cable channel.

There is already a so-called energy chain known (DE 298 20 1 17 U1), which contains a plurality of successively hanging, forming a flexible cable channel chain links, which each have a hollow cross-section transverse to the chain longitudinal direction. In this case, each two adjacent chain links about a hinge axis transverse to the chain longitudinal direction to one side by one

Angle pivoted against each other, and on the other side they are blocked in a straight-ahead position, in which the chain links form a straight cable channel. Such energy chains are usually used to ensure a power supply in various situations, but possibly also a water and compressed air supply, such as for lifts. Such lifts are used as so-called light hangers in TV studios, theaters and on show stages. A disadvantage of the known energy chain in question is that it can not be connected to at least one correspondingly constructed further energy chain for defining a plurality of parallel cable channels. Moreover, the known energy chain is not suitable for use in devices and in particular in household appliances due to their structure. In such devices receiving body without relatively pivotable members are usually used for receiving cables or wires. It is also a cable receiving device for the installation of motor vehicle wiring harnesses known (FR 26 33 1 1 1 A1). This cable receiving device has a plurality of receiving bodies of different cross-sections and shapes. By means of these nestable receiving body can be realized a cable receiving device which is adaptable to a predetermined topography of a motor vehicle chassis. In the case of the known cable receiving device in question, it is possible to provide a transverse branch for receiving cables or lines from a cable receiving channel extending in the longitudinal direction. However, nothing is known in the context in question as a cable receiving device can be extended with a longitudinal receiving body having at least two ends in the transverse direction of the respective receiving body by a corresponding longitudinal receiving body without a passage connection between the respective receiving bodies.

There is also known a modular electric line shielding system (US 2004/0102080 A1), in which pluggable elongated shielding segments are provided. These shield segments have mutually complementary connecting elements at their ends, with which correspondingly constructed shielding segments can be plugged together. Each shielding segment consists of two connected segment members, which are collapsible around the respectively to be shielded electrical line and held together by formed on their sides, mutually complementary snap elements. However, nothing is known in this context about an expandability of such a shielding system in the transverse direction relative to the shielding segments which are assembled in the longitudinal direction.

The invention is therefore based on the object, a cable receiving device of the type mentioned in such a way that this cable receiving device can be extended in a relatively simple manner and without much installation effort if needed in a short time so that said a receiving body with at least one other, constructed accordingly Receiving body in its transverse direction is connectable and that thus a plurality of parallel to each other extending receiving bodies with their own cable channels is connectable.

The above-described object is achieved in a cable receiving device of the aforementioned type according to the invention in that the receiving body in its transverse direction, relative to its longitudinal direction, has at least two mutually complementary connections. having training facilities, with which at least one further, provided with corresponding separate connection means receiving body is connectable.

The invention has the advantage that a Kabelaufnahmevor- device is created in a relatively simple manner, which with said one longitudinal receiving body at least one further, also provided with at least one cable channel for receiving one or more cables or lines receiving body such allows to connect that the respective receiving body are connected in parallel to each other. The connection of the respective receiving body is carried out simply by the provided in the respective receiving body transverse direction, mutually complementary connection means.

Advantageous developments of the invention are covered in the subclaims.

Thus, the respective receiving body and its connecting means are suitably formed contiguous. Due to the one-piece design of the respective receiving body and its connecting means can be significantly reduced in assembling a plurality of receiving bodies in the aforementioned manner, the assembly and labor costs.

According to a further expedient embodiment of the invention, the receiving body has a hollow cylindrical or a quadrangular cross-section, one cross-sectional side of which is open. In the case of a hollow-cylindrical body cross-section, cables and lines which are not to be accessible from the outside, for example, in the area of the respective receiving body, can easily be laid in the receiving body having this cross-section. It is also possible in an advantageous manner to form the respective receiving body as an electrical shielding body for each of these recorded cables or lines. On the other hand, in the case of the mentioned quadrangular cross-section of which one cross-sectional side is open, a simple cable laying from the open cross-sectional side of the receiving body is possible.

A particularly easy-to-use cable receiving device results according to yet another advantageous embodiment of the invention in that the said connection means provided at diametrically opposite points of the respective receiving body are. This also brings the advantage of a very simple one-dimensional expandability of the cable receiving device according to the invention, namely in the transverse direction of the above-mentioned a receiving body.

Conveniently, the receiving body made of plastic, which brings the advantage of ease of manufacture and low weight of the respective receiving body with it.

In the same way, however, it is advantageous if the said connecting devices are made of plastic.

According to a further advantageous embodiment of the invention, the connecting means are formed by plug-in and / or latching elements. As a result, receiving bodies which run parallel to each other can be connected to one another in a particularly simple manner with their respective connecting devices designed to be complementary to one another in a positive and / or non-positive manner.

According to yet another expedient embodiment of the present invention, the respective receiving body at its ends additional, mutually complementary connection means, with which at least one further, provided with corresponding additional connection means receiving body is connectable. This has the advantage that in a relatively simple manner an expandability of the cable receiving device according to the invention in a second direction or dimension is possible.

Expediently, the respective receiving body and its additional connecting devices are formed coherently here as well. This has the advantage of a particularly small design effort for the formation of the cable receiving device according to the invention with it.

The additional connecting devices are preferably provided with cable tie receptacles. As a result, the receiving body can be fixed in a particularly simple manner by means of cable ties on usually provided in devices holding elements. It is also advantageous if the additional connecting devices consist of plastic. This makes it possible to produce the entire cable receiving device in a particularly simple manner and with relatively low weight.

Conveniently, the additional connecting means are formed by plug-in and / or latching elements. This brings the advantage of a particularly simple and secure connection possibility of the respective receiving body in its longitudinal direction with it.

With reference to drawings, the invention is explained in more detail below by way of example. In the drawings, in which like or corresponding elements or parts are designated by like reference numerals, show

Fig. 6 is a greatly enlarged sectional view of a possible embodiment of additional connecting means of the cable receiving device according to the invention.

In Fig. 1, a cable receiving device according to an embodiment of the invention is shown schematically in a plan view. This cable receiving device includes a two opposite ends, longitudinally extending receiving body 1, which contains at least one cable channel for receiving one or more (not shown here) cables or lines. The receiving body 1, which consists for example of an electrically non-conductive plastic, may preferably have a hollow cylindrical cross section or a quadrangular cross section with an open cross-sectional side. In principle, the cross section in question can also be designed differently. Furthermore, the cable receiving device shown in FIG. 1 has a second receiving body 2, which is of the same length as the receiving body 1 and the back visibly its cross section and otherwise may be formed in the same way as the receiving body. 1

According to FIG. 1, the two receiving bodies 1 and 2 arranged parallel to one another are shown with a rather basic length. In principle, however, receiving body of different lengths can be connected to each other. One of the two receiving bodies 1, 2 may be provided, for example, for receiving control and signal lines or cables, and the other receiving body may serve to receive power supply lines.

The two receiving bodies 1 and 2 shown in Fig. 1 are connected to each other by means of separate, mutually complementary trained connecting means 3, 4, which are provided on or in each of the two receiving bodies 1, 2 shown. According to Fig. 1, these connecting means, of which three pairs are provided, on the one hand designed as a plug 3 and the other as a plug receptacles 4, in the corresponding plug 3 can be inserted. By thus formed connecting means at diametrically opposite locations of the receiving body 1, 2, the respective receiving body 1, 2 can be positively connected to each other in the present case. At this point it should be noted that the plug 3 shown in FIG. 1 are provided by means of spacers 5 or connected to their associated receiving bodies 1 and 2, for example by joint production of all just mentioned elements made of a plastic.

When assembling the two receiving body 1, 2 shown in Fig. 1 remains between the longitudinal sides of a distance 6, which may be equal to the thickness or height of the respective spacer 5 or, as shown in FIG. 1, is slightly smaller than this Thickness or height. According to FIG. 1, the spacers 5 provided on the receiving body 2 protrude into corresponding (unspecified) plug receptacles of the receiving body 1.

The two receiving bodies 1 and 2 shown in Fig. 1 are also provided at their longitudinal ends with additional connecting means 7 and 8, which are complementary to each other. The respective additional connecting devices 7 and 8 are designed to be complementary to one another in such a way that each of the receiving bodies 1, 2 can be connected in a longitudinal direction with at least one further receiving body provided with corresponding connecting devices 7 or 8, as described below with reference to FIG. 5 will be explained in more detail. These additional connecting devices 7 and 8 are otherwise designed so that they at least in the non-extended state - that is, if their associated receiving body is not connected to a further receiving body - but preferably also in the assembled state - so if their associated receiving body is connected to a further receiving body - the receiving body 1, 2 are provided with Kabelbinderaufnahmen 9. By this Kabelbinderaufnahmen 9, the receiving body 1, 2 can be fixed by means of conventional cable ties to holding elements, which are usually provided in devices at a number of locations.

As in the description of the cable receiving device shown in Fig. 1, the two connecting devices 3, 4 are each formed by a plug 3 and a female receptacle 4. Thus, the receiving body 1 and 2 shown in Fig. 1 can be positively connected to each other by means of these two connection means 3, 4. However, as mentioned above, in addition or as a substitute to a frictional connection between the respective receiving bodies 1, 2 may be provided. In this case, the two connection devices 3, 4 are then preferably formed as latching elements designed to be complementary to each other.

Fig. 2 shows in a greatly enlarged sectional view of a possible embodiment of the aforementioned connecting means 3, 4 between the adjacent receiving bodies 1, 2, for a positive and non-positive connection of the two receiving body 1, 2. It is on the receiving body 1 provided plug - which is here designated by 3 ^' - provided at its distal end with a locking lug 10 in the form of a thickening, which is received by a correspondingly shaped receiving hole 1 1 here 4 ^' designated plug receptacle of the receiving body 2 in a Schieberastverbindung. This slide-load connection can of course be solved by pulling out the plug 3 ^' from the connector receptacle 4' again.

Fig. 3 shows schematically in plan view one of the two receiving body shown in Fig. 1, namely the receiving body 1, which is a long receiving body. With respect to this long receiving body 1, only dimensions which are considered essential for the present invention are designated in greater detail in FIG. Thus, a center distance between the in Fig. 1 denoted by 3, 4, adjacent connecting means of FIG. 3 given by A. This means that the illustrated in Fig. 1 and 3, provided in the longitudinal direction of the respective receiving body 1, 2 three Pairs of connecting means (designated by 3, 4 in Fig. 1) are equidistant from each other at equal intervals A. The distances from the centers of the connecting devices 3, 4 provided near the outer ends of the long receiving body 1 shown in FIG. 3 to the respective adjacent outer edge of the receiving body 1 are in each case B.

According to FIG. 3, the connecting devices provided at the two opposite ends of the receiving body 1 (designated by 7, 8 in FIG. 1) each have a length of C.

Thus, the total length LL of the long receiving body 1 shown in FIG. 3 satisfies the relation LL = 2 (A ₊ B + C).

Fig. 4 shows a schematic plan view of a short receiving body 1 'of the cable receiving device according to the invention. The short receiving body 1 'shown in FIG. 4 has, compared with the long receiving body 1 shown in FIG. 3, only two pairs of connecting devices (designated in FIG. 1 with 3, 4) in its transverse direction, which in the longitudinal direction of the receiving body 1'. are provided at a center distance A from each other at a distance.

The distances from the centers of the connecting devices 3, 4 provided near the outer ends of the receiving body 1 'shown in FIG. 4 to the respective adjacent outer edge of the receiving body 1 are in each case B.

According to FIG. 4, the connecting devices provided at the two opposite ends of the receiving body 1 '(denoted by 7, 8 in FIG. 1) each have a length of C.

Thus, the total length LK of the short accommodating body 1 'shown in FIG. 4 satisfies the relation LK = A + 2 (B + C).

5 shows a plan view of a detail of a connecting region, for example between the two longitudinally connected receiving bodies 1 and 1 'of the cable receiving device according to the invention.

As is apparent from Fig. 5, the two receiving body 1, 1 'with the provided at their opposite ends additional connecting means - in Fig. 1 with the 7th or 8 are designated - connected to one another such that only a distance C remains between the opposite outer edges of the two receiving body 1 and 1 '. This means that the connecting devices provided at the opposite ends of the two receiving bodies 1 and 1 'are practically pushed into one another since they each had a length of C prior to their connection.

Furthermore, it is apparent from Fig. 5 that the center distance between the provided in or on the respective receiving bodies 1 and 1 'and in the immediate vicinity of the ends of these interconnected receiving body 1 and 1' provided connecting means - in Fig. 1 with the third or 4 are referred to - the above-mentioned center distance A is. Using the ratios shown in FIGS. 3 and 4, it follows that the center distance or the length A thus satisfies the relationship A = 2B + C. Furthermore, it can be seen that the connecting devices in the transverse direction of the receiving bodies, which are connected to one another in the longitudinal direction, which are designated by 3, 4 in FIG. 1, are each provided equidistantly from one another at a distance. This contributes to a particularly stable connection of interconnected receiving bodies, which are extended in their longitudinal direction by corresponding receiving body.

Fig. 6 shows in a greatly enlarged sectional view a possible embodiment of the additional connecting means indicated in Figs. 1, 7, 8 provided at opposite ends of each longitudinal receiving body of the cable receiving device according to the invention. These additional connecting devices 7, 8 are formed in the present case by latching elements 12, 13 which lock together by pushing together the corresponding ends of receiving bodies, such as the receiving body 1 and 1 'and thus here to a positive and non-positive connection of the respective receiving body 1, 1 'lead. In this context, it should also be noted that, in principle, the relevant additional connecting devices 7, 8 can also do without latching elements, for example, only with plug-in or sliding elements and their receiving devices.

The connecting devices 3, 4 and 7, 8 consist here as their respective associated receiving body 1, 2 or 1, 1 'preferably made of an electrically non-conductive plastic. However, the relevant connecting devices 3, 4 or 7, 8 may optionally also be made of metal and be embedded in the associated receiving body 1, 2 or 1, 1 '. Moreover, the respective receiving body and its associated connecting means entirely made of metal exist or provided with an electrically conductive material layer, that is to be coated, for example, if an electrical shielding of the recorded by the respective receiving body and its connection means cables or lines is required.

Finally, it should be noted that with the receiving bodies 1, 1 'and 2 of the cable receiving device according to the invention not only similar receiving body with optionally different lengths can be connected, but quite well receiving body, which formed differently with respect to the previously described longitudinally extending receiving body are. Thus, it is readily possible to use, for example, cross-shaped receiving body with a total of four connecting ends, T-shaped receiving body with three connecting ends and / or according to a quarter circle curved receiving body and / or other devices, such as controller holder, which with appropriately shaped and with connecting devices or Additional receiving means according to the invention receiving bodies and / or to be connected to the above-mentioned longitudinal receiving bodies. In the case of T-shaped receiving bodies, the two connecting ends associated with a direct passage area will be provided with mutually complementary connecting means, and the third connecting end corresponding to a transverse discharge from this passage area will then be formed with one of the connecting means located at both ends of the passage area of the respective one T-shaped receiving body are provided. Thus, such receiving body can be connected with this Abzweigungsende of the T-shaped receiving body, as they have been previously explained.
