Description

The present invention relates to a cable receiving device for receiving a flat end of a cable and a contact system. A cable receiving device according to the preamble of claim 1 is from the document WO 96/31920 known.

In many electrical or electronic devices, for example, ribbon cables or round cables with at least one flat end are conventionally used for bus lines. In such a cable, a plurality of conductors are embedded in an insulating film or each sheathed by an insulation, wherein the individual conductors have a small cross-section and a small distance from each other. To connect such a cable, for example, with a board or an electrical or electronic device, a plug of the cable is regularly connected to a corresponding socket. Alternatively, so-called "zero-insertion-force"("ZIF") connectors can be used, by means of which one end of a cable is inserted into the "ZIF" connector with only minimal force so that electrical contact is made. Since the connection between the cable and "ZIF" connector is already made with very little effort, the force required to release the connection is low, so that the electrical connection can be interrupted unintentionally.

pamphlet WO 96/31920 A1 discloses a ribbon cable connector assembly having a ribbon cable end provided with a locking rib and a connector housing having a cable insertion opening and adjacent thereto a resilient locking arm having a locking shoulder cooperating with the locking rib.

pamphlet DE 1 286 171 B discloses a contact device for producing a contact spring strip, in which each contact unit has at least two mutually independently contacting contact spring wires.

pamphlet GB 2 067 361 A discloses a connector for a ribbon cable having terminal members each having a contact portion and a terminal portion, and latch members for locking the terminal members to the connector.

pamphlet US 2007/0054544 A1 discloses a holder adapted to receive and contact an end portion of a ribbon cable, the holder having a pair of clamping means clamping the smooth end portion of the ribbon cable.

It is an object of the present invention to provide a device or system for enabling detachable electrical connections which, when used easily, have improved solubility and a high connection reliability.

The object is achieved by a cable receiving device according to claim 1 and a contact system according to claim 8. Preferred embodiments are subject of the dependent claims.

Advantageously, it is possible by means of the cable receiving device to accommodate a plugless flat end portion of a cable or a flat Kabelendbereich through the Einführöffnungsabschnitt. Preferably, the male cord has adjacent electrical conductors. The inserted portion of the flat end portion of the cable or the flat Kabelendbereichs further comprises a stiffening element. Since the plug-less cable has only one stiffening element, the end or the end region of the cable, in contrast to cables with plugs, has a particularly simple construction, functions reliably and can be produced cost-effectively. Advantageously, the stiffening element is at least partially arranged flat on or on the juxtaposed electrical conductor having flat end portion of the cable. The stiffening element can preferably also via this range juxtaposed electrical conductor range or extend beyond, in particular in the direction of an insertion direction E, so that at least a portion of the flat Kabelendbereichs is initially introduced into the cable receiving device, which consists essentially only of the stiffening element. However, it is also possible that both a portion of the stiffening member and a portion of the flat end portion of the cable is insertable into the interior of the cable receiving apparatus.

definitions

For a better understanding of the present invention, a plurality of the terms used will be defined and explained below.

The term "flat end region" of a cable as used in the context of this invention essentially describes an arrangement of the conductors of the cable in an area near one end of the cable. In particular, the conductors in the flat end region of the cable are arranged substantially parallel, wherein the conductors are arranged in the flat end region, for example, substantially parallel to a common plane or are arranged in a common plane. It is also possible that a plurality of layers of conductors are present, wherein the conductors of a layer are arranged substantially in a common plane and the conductors of another layer are arranged substantially in a further common plane, etc. The common planes are substantially parallel to each other and preferably substantially parallel to the insertion direction E.

Specifically, the insertion opening portion has a shape having a long side along a longitudinal direction L and a short side. The term "longitudinal side", as used in the context of this invention, describes a side of the Einführöffnungsabschnitts which at least by a factor of 2, preferably by a factor of 4, the factor 8, the factor 10, the factor 15, the factor 20, the factor 50, etc. is longer than the short side. The long side can also be called "wide side" and "width" of the Einführöffnungsabschnitts be designated. For example, the insertion opening portion may have a substantially rectangular opening with one side of the rectangular opening being longer than the other. The longer side is called the long side. The same applies mutatis mutandis, for example, for an oval or elliptical opening, for example, the longer major axis opposite side is referred to as a longitudinal side, wherein the longitudinal direction L is preferably defined as parallel to the longer main axis. Furthermore, the preceding statements apply mutatis mutandis to a trapezoidal insertion, etc.

The insertion direction E and the longitudinal direction L are substantially perpendicular to each other and span a plane. Substantially parallel to this plane extends the portion of the flat end portion of the cable to be inserted. Substantially perpendicular to this plane is a locking direction V.

The contacting of the electrical conductors of the cable can be effected directly or indirectly via contact regions of the stiffening element, which in turn are contacted accordingly with the conductors of the cable.

The cable receiving device further comprises at least one electrical contact element, which is designed to make electrical contact directly with the at least one conductor of the cable. The electrical contact between the at least one electrical contact element and the at least one conductor of the cable can also be effected indirectly via at least one contact region of the stiffening element. The at least one electrical contact element is at least partially disposed in the interior of the cable receiving device. In particular, the component (s) of the at least one electrical contact element is or are arranged in the interior of the cable receiving device, which contact the at least one electrical conductor of the cable.

Furthermore, the cable receiving device comprises at least one retaining element which is resilient. The term "recoverable" as used in the context of this invention is understood, describes that the at least one holding element after a mechanical load or elastic or plastic deformation by a force in a loading direction substantially returns to the original shape and / or position. The mechanical loading or deformation of the at least one retaining element takes place, for example, during insertion of a partial region or part of the flat cable end region along the insertion direction E into the interior of the cable receiving device, whereby a force in the loading direction is applied to the retaining element by means of the inserted portion of the cable end region which is substantially perpendicular to the insertion direction. The at least one holding element brings about a correspondingly equal reaction force. The loading direction and locking direction V may be substantially parallel or antiparallel to each other.

Further, at least one protrusion is disposed on the longitudinal side of the insertion opening portion such that the stiffening member disposed on the flat end portion of the cable end passes through this protrusion during insertion of at least a portion of the flat cable end portion and, preferably after insertion into the operating position Shoulder of the stiffening element comes with the projection in positive engagement, ie, the contours of the projection and the shoulder at least partially intermesh or contact each other, so that a frictional connection and / or a frictional engagement between the projection and the shoulder. The positive engagement is advantageously carried out by a displacement of the shoulder of the stiffening element relative to the projection in a standing substantially perpendicular to the insertion direction E locking direction V. Here, the projection can be moved substantially parallel to the locking direction V, at substantially in the locking direction V unmoved shoulder. It is also the shoulder substantially parallel to the locking direction V, to be moved in substantially in the locking direction V unmoved projection. But it can also be the shoulder and the projection are moved substantially parallel to the locking direction V.

In this case, the shoulder of the stiffening element can be both an outer edge of the body of the stiffening element and arranged on the body of the stiffening element recess, groove or groove and / or projection.

The shoulder of the stiffening element and the projection of the Einführöffnungsabschnitts are in operational use of the cable receiving device, ie, when an end portion of the cable is inserted at least partially into the interior of the cable receiving device and in particular electrical contact between the at least one electrical contact element and the at least one electrical conductor of the cable is made in positive engagement. The term "positive engagement", as used in the context of this invention, describes that, for example, contours of the projection and the shoulder mesh at least partially or contact each other, so that a frictional connection and / or a frictional engagement between the projection and the shoulder. In other words, for example, two or more surfaces are abutted against each other such that when the force is applied substantially parallel to the direction of insertion (i.e., substantially in the direction of insertion or substantially opposite to the direction of insertion), the two abutting surfaces are not movable. The term "form-fitting", as used in the context of the invention describes in particular that touch the projection and the stiffening element in some areas so that resulting from the positive friction and / or frictional connection in particular a movement of the stiffening element and thus the cable end in a direction opposite to the insertion direction is substantially not possible. In particular, a movement of the cable end region against the insertion direction is only possible if the shoulder of the stiffening element and the projection of the Einführöffnungsabschnitts are moved relative to each other in parallel to a locking direction. In other words, due to the positive connection, the cable end region is locked in the cable receiving device.

Due to the locking, it is advantageously not possible that the flat End of the cable dissolves force, provided that the force acting is so small that no damage or destruction of the cable or the cable receiving device takes place, and the electrical contact between the cable and a device is partially or completely interrupted. Conveniently, the locking takes place due to a significant displacement movement and is advantageously accompanied by a corresponding locking sound, so that when assembling a perfect connection can be determined beyond doubt. Thus, the installation of a cable connection can be performed quickly and accurately. Mounting errors and / or poor contact can be avoided.

Preferred embodiments of the cable receiving device

According to a preferred embodiment, at least a portion of the Einführöffnungsabschnitts is formed as a resilient retaining element. In particular, a portion of the Einführöffnungsabschnitts be formed elastically, that is, this portion of the Einführöffnungsabschnitts is designed such that it is deformed during the insertion of a portion of a cable, in particular a Kabelendbereichs, and after insertion of the portion, preferably with the release of a locking noise substantially returns to its original position. The deformation may be elastic and / or at least partially plastic.

In particular, the Einführöffnungsabschnitt is formed such that the at least one projection is displaced or deformed in the substantially perpendicular to the insertion direction E locking direction V. After insertion of the cable end portion, the deformed portion substantially returns to its original shape and / or position. In particular, the at least one projection is located after the insertion or insertion of the cable end region or the stiffening element in its locking position. The locking position may be substantially equal to a basic position of the at least one projection, ie substantially equal to a spatial position prior to insertion of a cable end region, wherein the at least one projection is positively connected to a shoulder of the stiffening element.

Advantageously, in a further preferred embodiment, at least one electrical contact element is formed as a resilient retaining element. Thus, in particular a partially curved electrical contact element can be formed elastically biased. In particular, the electrical contact element is resiliently biased by at least partially inserting the flat end region of the cable, whereby the electrical contact element exerts a force in the locking direction V on the cable end region. Advantageously, after insertion of the cable end region, in particular of the stiffening element, a displacement of at least the shoulder of the stiffening element takes place due to a force which is applied by the at least one pretensioned during insertion retaining element. The displacement takes place essentially in the locking direction V.

In a particularly preferred manner, at least one electrical contact element is resilient, in particular designed as a resilient element, which preferably has two legs and a bent portion arranged between the legs. In this case, preferably, a first leg extends substantially parallel to the insertion direction and a second leg is arranged in a ground state, ie in a state without mechanical stress, with the first leg preferably at an angle α of about 0 to about 90 degrees. Further preferably, the at least one electrical contact element is designed and arranged such that the angle α is reduced by the insertion of the flat end portion of a cable, the resilient contact element is then elastically biased and can exert a force in the locking direction V on the Kabelendbereich.

A further preferred embodiment may in particular comprise both an insertion opening section designed at least in regions as a resilient retaining element and at least one electrical contact element designed as a resilient retaining element.

According to a further preferred embodiment, the Einführöffnungsabschnitt is tapered towards the interior of the cable receiving device, so that the Kabelendbereich advantageously can be particularly easily introduced into the interior.

In a particularly preferred manner, the Einführöffnungsabschnitt a recess, so that manually or by means of a tool against the locking direction V on a portion of the flat end portion of the cable is transferable, that the positive connection between the at least one shoulder of the stiffening element of the cable and the at least one projection is solved. For example, can be pressed by means of a screwdriver on the inserted portion of the cable end, so that the inner portion located in the cable against the force of the at least one holding element against the locking direction V moves. Thereby, the positive engagement between the present at the Einführöffnungsabschnitt projection and the stiffening element can be lifted, so that the inserted portion of the cable can be pulled out against the insertion direction E from the cable receiving device. The recess may also divide the projection, so that, for example, two projections are present.

Preferably, the cable receiving device comprises at least one locking means receiving, which is adapted to engage with at least one locking means. In particular, the locking means receptacle may comprise or be a projection and / or a recess and / or a recess. The locking means receptacle is advantageously arranged at a distance from the insertion opening section.

Advantageously, at least one projection after the at least partially insertion or the at least partial insertion of the stiffening element into the interior of the cable receiving device with at least one shoulder of the stiffening element in positive engagement, so that the flat Kabelendbereich is locked in the cable receiving device. In particular, the positive engagement is effected by an at least partially displacement of the stiffening element along the locking direction V relative to the projection. The positive connection can preferably be canceled only by a force directed counter to the locking direction V, as a result of which the cable end region is unlocked.

Further advantageously, the contact system thus allows a simple and secure locking of the end portion of the cable with the Cable receiving device, wherein the cable end does not have to be arranged on a complicated connector or the conductor of the cable must not be inserted into a connector and connected to contact elements of the plug. Rather, only a stiffening element is arranged on the cable, which allows a lock with the cable receiving device.

In order to prevent unwanted unlocking, preferably at least one retaining element exerts a force in a locking direction V on the flat cable end region.

Preferably, the stiffening element of the contact system comprises a locking element which can be fastened by gluing and / or welding and / or clamping to the stiffening element. The locking element may also be formed integrally with the stiffening element.

FIG. 1 shows a perspective view of a preferred embodiment of a contact system 1 comprising a cable receiving device 2, in which a flat portion of a cable 3 is inserted in the insertion direction E. The cable receiving device 2 comprises an insertion opening section 6. The insertion opening section 6 has a substantially rectangular shape, the long side (also referred to as longitudinal side) extending along the longitudinal direction L being longer than the short side by a factor greater than 8 , In other words, the insertion opening has a long and a short side. The insertion opening may also be square and the aforesaid long side is a side of the insertion opening which contributes to a flat end portion of the cable opposite to a surface of the flat end portion of the cable next page. The device-side electrical contacting takes place via the outer contacts 15.

Furthermore, the in Fig. 1 As shown preferred embodiment has two projections 7 on the holding member 11 and a recess 9 on the long side of the Einführöffnungsabschnitts 6. The two projections are spatially separated by the recess 9. A visible in the recess 9 shoulder 8 of a stiffening element 5 is positively connected to the projections 7, so that the cable 3 is locked in the cable receiving device 2. By applying a tool, such as a screwdriver, in the region of the recess 9 and the application of a force on the shoulder 8 opposite to the locking direction V, the introduced portion of the cable 3 against the locking direction V are displaced, so that the positive engagement of the shoulder 8 of Stiffening element with the projections 7 is released. Thereafter, the introduced portion of the cable 3 can be pulled out of the cable receiving device 2 counter to the insertion direction E.

The insertion of the stiffening element 5 in the cable receiving device 2 can be done manually. The stiffening element 5 can be made, for example, with a manually operated tool, such as a screwdriver (not shown). Here, for example, by means of the recess 9, the screwdriver for guiding or for pushing the stiffening element can still be used even if the stiffening element is already introduced into the Einführöffnungsabschnitt. For example, the stiffening element may already be substantially completely inserted into the cable receiving device, but not yet so far that the shoulder 8 and the projection or projections 7 engage behind one another. Complete manual insertion without a tool is difficult. However, by means of the screwdriver (or other suitably useful tool), the stiffening element can be further inserted into the cable receiving device.

Alternatively, a semiautomatic or a fully automatic tool, for example, a pick and place machine can be used to introduce the Kabelendbereich in the cable receiving device, as with the aid of a tool, a directed force in the direction of insertion direction E can be applied to the stiffening element 5.

FIG. 2 shows a section through an embodiment of the cable receiving device 2 in the ground state, ie without an inserted cable 3 (in Fig. 3 shown). In the Fig. 2 shown embodiment of the cable receiving device 2 has at least one electrical contact element 10 with at least one outer contact 15, which are integrally formed together. The electrical contact element 10 and the outer contact 15 may also be separate components, which, however, are electrically and / or mechanically interconnected. A region of the electrical contact element 10 is designed as a resilient holding element 11, which has two legs 12, 14 and a bent region 13 arranged between the legs 12, 14. In this case, a first leg 12 extends substantially parallel to the insertion direction E. The second leg 14 is in the ground state or mechanically unloaded state and includes (in the ground state) with the first leg 12 an angle α of about 30 °. The angle α is preferably in a range of about 0 ° to about 90 °, more preferably between about 20 ° and about 45 °. The distal end of the leg 14 from the bent portion 13 is free to move freely. This distal end portion is further bent, wherein the curvature is formed such that the concave-shaped side of the leg 14 faces away from the Einführöffnungsabschnitt 6. By inserting the flat end portion 4 of the cable 3 (as in Fig. 3 shown), the leg 14 is moved against the locking direction V along the loading direction B and the angle α is reduced, whereby the at least one resilient contact element 10 is resiliently biased.

In this embodiment, the Einführöffnungsabschnitt 6 is formed substantially rigid, that is, the Einführöffnungsabschnitt 6 is designed such that it passes through the insertion of a portion of a cable 3 is not deformed, that is stiff or dimensionally stable.

In addition, the Einführöffnungsabschnitt 6 is designed to the interior of the cable receiving device 2 towards preferably tapered in a region 16, so that a cable end 18 and subsequently a Kabelendbereich 4 can be advantageously particularly easily introduced into the interior. In addition, an insertion of the stiffening element 5 (in Fig. 3 shown) in the tapered portion 16 lead to an elastic deformation of the stiffening element 5 when it passes through the tapered portion 16 and the projection 7 of the Einführöffnungsabschnitts 6 led to the upper edge 17 of the interior of the cable receiving device 2 and deflected or bent, ie elastic and / or at least partially plastically deformed. In particular, the proximal to the projection 7 region of the stiffening element 5 displaces relative to the distal region of the stiffening element 5 against the locking direction V. After insertion of the stiffening element 5, this deformation of the stiffening element 5 can relax, in particular the proximal to the projection region of the stiffening element in Locking direction V shifts and the positive engagement takes place with the projection 7.

In addition, the at least one prestressed contact element 10 exerts a force on the stiffening element 5 in the locking direction V.

FIG. 3 shows a section through an embodiment of the contact system 1, comprising a cable receiving device 2 with inserted and locked end portion 4 of a cable. 3

In the Fig. 3 Shown embodiment of the Kabelendbereiches 4 has a stiffening element 5, which is partially fixed surface on the electrical conductor having flat end portion 4 of the cable 3, for example, by a bond, attached. Advantageously, the stiffening element 5 protrudes in the direction of the insertion direction E over this electrical conductor having region of the cable 3. In other words, in the in FIG. 3 embodiment shown, the cable end 18 identical to the end of the stiffening element 5, wherein the stiffening element 5 protrudes beyond the end 19 of the conductors. However, it is also possible that the end 19 of the conductor coincides with the end of the stiffening element 5 and together form the cable end 18. Alternatively, the end 19 of the ladder may protrude beyond the end of the stiffening element and thus the end 19 of the ladder may form the flat cable end 18.

When inserting the flat end portion 4 of the cable 3 in the Einführöffnungsabschnitt 6 therefore the stiffening element 5 is first introduced into the cable receiving device 2. As a result, the electrical conductors of the cable 3 are protected against mechanical stress.

In this embodiment, the stiffening element 5 has at least one electrical contact region, which is electrically connected at least to one electrical conductor of the cable 3. The at least one electrical contact region can be contacted by at least one contact element 10, so that the electrical connection to at least one conductor of the cable 3 is made indirectly via the stiffening element 5. This applies mutatis mutandis to a plurality of conductors and electrical contact areas, such as 2, 3, 5, 10, 15, 25, 50, etc. conductors and for a corresponding number of contact areas of the stiffening element. 5

In the Fig. 3 shown embodiment of the cable receiving device 2 has analogous to that in Fig. 2 shown embodiment, at least one electrical contact element 10, which is formed integrally with the outer contact 15. A region of the electrical contact element 10 is formed as a resilient holding element 11.

Figure 3 shows an electrical contact element 10, which has two legs 12, 14 and a bent portion 13 arranged between the legs 12, 14 in a contacted and loaded condition. In this case, the first leg 12 extends substantially parallel to the insertion direction E. The second leg 14 is in the loaded state and includes with the first leg 12 an angle α of about -15 degrees. A negative angle α means that the bent portion 13 bounded by the legs 12, 14 has a bend greater than 180 degrees. At a 180 degree bend, both legs are parallel and spaced apart and the included angle α is 0 degrees. At a bend greater than 180 degrees, leg 14 points in the direction of leg 12 and the included angle α is less than 0 degrees. The extended leg 14 would therefore intersect the leg 12. At a bend less than 180 degrees, especially in the unloaded state, the included angle α is greater than 0 degrees. The distal end of the leg 14 from the bent portion 13 is free to move freely. This distal end portion is further formed bent, wherein the curvature is formed such that the convex-shaped side of the leg faces the Einführöffnungsabschnitt. By inserting the flat end portion 4 of the cable 3, the leg 14 is moved counter to the locking direction V along the loading direction B and the angle α is reduced, whereby the at least one resilient contact element 10 is elastically biased.

In this embodiment, the Einführöffnungsabschnitt 6 is at least partially formed elastically and / or plastically deformable to act as a holding element 11. That is, the Einführöffnungsabschnitt 6 is designed such that it is during insertion of a portion of a cable, in particular in the locking direction V along a second loading direction B ', deformed and after an at least partially insertion of the Kabelendbereichs 4, preferably releasing a locking noise substantially returns to its original shape and / or location. Preferably, the Einführöffnungsabschnitt 6 is deformed during insertion in the region of the projection 7 such that the projection 7 displaced in the locking direction V. In the meantime, the region of the stiffening element 5 which is proximal to the projection 7 can in particular also be relative to the distal region of the Relocate stiffening element 5 against the locking direction V and / or deform. After insertion of the cable end region, the projection 7 displaces and / or deforms again counter to the locking direction V and returns substantially to the original position. In particular, the region of the stiffening element 5 proximal to the projection 7 can also be displaced and / or deformed relative to the distal region of the stiffening element 5 along the locking direction V.

After insertion of the stiffening element, the projection 7 is substantially in its home position, i. in the spatial position before insertion of the cable end region, wherein the projection 7 is positively connected to a region of the stiffening element 5.

In addition, the Einführöffnungsabschnitt 6 to the interior of the cable receiving device 2 toward, for example, in a region 16 tapers, so that a cable end 18 can be advantageously particularly easily introduced into the interior.

FIG. 4 shows a perspective view of a preferred embodiment of a contact system 1 comprising a cable receiving device 2 and a flat portion 4 of a cable. 3

In Figure 4 not visible, the stiffening element 5 at least one shoulder 8, which can be connected at least partially positively with the projections 7 of the cable receiving device 2. Furthermore, the flat portion 4 of the cable 3 comprises a locking element 20 arranged on the stiffening element 5. The locking element 20 is fastened to the stiffening element 5. The attachment can be done for example by gluing and / or welding and / or clamping and / or the like. Preferably, the stiffening element 5 and the locking element 20 may be integrally formed. The locking member 20 includes a locking means 21, which is formed in this embodiment as a projection. The Locking means 21 is preferably formed integrally and resiliently with the locking element so that it can be displaced and / or deformed by a force in a third loading direction B "and, after the force has been acted upon, substantially in the original position and / or shape returns.

The locking element 20 advantageously facilitates the operation or the handling of the contact system 1. Preferably, the locking element 20 can serve as a handle to guide the flat portion 4 of the cable 3 into the cable receiving device 2. Further preferably, the operation of the locking element 20 may include the application of a force, wherein the force opposite to the locking direction V for canceling the positive connection of the shoulder 8 of the stiffening element 5 with the projections 7 manually, in particular without a tool applied. Advantageously, the inserted portion of the cable 3 can thus be pulled out of the cable receiving device 2 without using a tool, counter to the direction of insertion E. In particular, it is also possible by means of the locking element 20, the cable end region completely manually, without the need for a further tool to introduce into the cable receiving device and lock it.

The cable receiving device 2 of this embodiment basically has the features of Figs Fig.1 shown embodiment. Therefore, in the following, only from the description to Fig.1 deviating or additional features described.

In Figure 4 two projections 7 of the holding member 11 are shown, which are arranged separated by a recess 9 on the long side of the Einführöffnungsabschnitts 6. the retaining element can also have more than two projections. Furthermore, a recess 22 is formed as a preferred locking means receptacle 22 in a region of the cable receiving device 2. The area of the cable receiving device 2 is further in the insertion direction E behind the Recess 9 and spaced therefrom arranged. The recess 22 is designed to engage with the latching element 20 of the flat cable end 4 arranged locking means 21 into engagement. In particular, the locking means 21 can be positioned by means of the operation of the locking element 20 so that the locking means 21 engages with the recess 22 in engagement.

FIG. 5 shows a section through an embodiment of the contact system 1, comprising a cable receiving device 2 and an end portion 4 of a cable. 3

In the Fig. 5 shown embodiment of the cable end 4 has a stiffening element 5, which, as in Figure 4 described, a locking element 20 comprises, in particular stiffening element 5 and locking element 20 are made in one piece. Advantageously, the stiffening element 5 protrudes in the direction of the insertion direction E not beyond the electrical conductor having region of the cable 3 addition.
