Definitions
- Connection arrangement for connecting an electrical cable
- the invention relates to a connection arrangement for connecting an electrical line.
- Such a connection arrangement comprises a housing which has a plug-in opening into which the electrical line can be plugged in order to connect to the connection arrangement.
- a contact element for making electrical contact with the electrical line is arranged on the housing.
- a spring element is also arranged on the housing, which has a clamping leg which is designed to act on the electrical line in order to bring the electrical line into contact with the contact element when the electrical line is plugged into the plug-in opening.
- An actuating element can be actuated by a user in order to adjust the clamping leg.
- the actuating element can be adjusted from a non-actuated position to an actuated position, for example using a tool, in order to adjust the clamping leg in the actuated position, for example to make it easier to insert the electrical line into the plug-in opening or to remove the electrical line from the plug-in opening.
- connection arrangement realizes a spring force connection by using the spring element, in which the electrical line in the connected position is clamped to the contact element under the elastic spring action of the spring element and is thus electrically connected to the contact element.
- a spring element in the form of a tension spring is provided, which draws a connected electrical line into contact with an associated contact element by means of an elastic spring effect and thus creates a clamped connection between the electrical line and the contact element.
- the electrical line is pushed through an opening in the clamping leg when attached and is clamped between the clamping leg and the contact element in the connected position.
- connection arrangement of DE 10 2019 127 464 B3 provides a locking device, via which the clamping leg is locked in a release position relative to the housing.
- the locking device is triggered and the locking is thus released, so that the clamping leg is moved from the release position and the electrical cable is thereby connected to the contact element. jammed.
- a tool for example a screwdriver, can be attached to the connection arrangement and a force can thereby be exerted on the clamping leg.
- an actuating element in the form of a so-called pusher is provided, which can be pressed into the housing of the connection arrangement in order to act on the clamping leg and to move the clamping leg into its release position.
- the actuating element is spring-loaded relative to the housing of the connection arrangement via a tension spring in the form of a compression spring.
- an actuating lug is arranged on the actuating element, which is hooked onto a fastening section of a holding element when the actuating element is in the actuated position.
- the object of the present invention is to provide a connection arrangement which makes it possible in a simple manner to hold the clamping leg of the spring element in a release position and to transfer it into a clamping position when an electrical cable is inserted.
- connection arrangement has a trigger element which has a support end arranged stationary relative to the housing and a trigger leg which is elastically adjustable relative to the support end.
- the actuating element is designed to latch with the trigger element in the actuated position so that the actuating element is held in the actuated position.
- the trigger leg is designed to interact with the electrical line when plugged into the plug opening to release the actuating element from the actuated position.
- the connection arrangement also has a line guide arrangement which guides the line to be connected to the trigger element.
- the electrical cable is electrically contacted with the electrical contact element by inserting the electrical cable into the plug-in opening.
- Line of the clamping leg acts on the electrical line and loads it spring-elastically in the direction of contact with the contact element.
- the clamping leg of the spring element can be elastically deflected by actuating the actuating element, in order to transfer the clamping leg into a release position in which a space in the area of the plug opening is released and thus the electrical line can be plugged into the plug opening in a substantially forceless manner or (alternatively) a connected electrical line can be easily removed from the connection arrangement.
- the actuating element can, for example, be designed in the manner of a push-button and can be pressed into the housing by user actuation while pivoting relative to the housing, in order to act on the clamping leg in this way and adjust the clamping leg in the direction of the release position.
- the actuating element which is pivotably mounted on the housing, locks in the actuated position with a release element, which is supported by a support end on the housing or on a part connected to the housing. In the actuated position, the actuating element is thus held in position by the release element, so that the clamping leg of the spring element is also held in its release position, in which an electrical line can be easily attached to the connection arrangement or a connected line can be removed from the connection arrangement in a substantially forceless manner.
- the trigger element is used to lock with the actuating element in the actuated position.
- the clamping leg can be adjusted relative to the housing and transferred to a release position, so that in particular it is possible to simply insert an electrical cable into the plug opening of the housing to connect the cable to the connection arrangement.
- the trigger element is also used to trigger the actuating element from the actuated position in order to automatically release the actuating element from the actuated position when the electrical cable is inserted into the plug opening and thus to transfer the clamping leg into a clamping position in which the electrical cable inserted into the plug opening is electrically contacted with the contact element of the connection arrangement.
- the trigger element has a trigger leg which is designed to interact with the electrical cable when it is inserted into the plug opening.
- the trigger leg is triggered by interaction with the electrical cable, so that the actuating element is locked with the trigger element is lifted and the actuating element is thus released from the actuated position.
- the actuating element can move back towards the non-actuated position, in particular automatically, preferably under spring preload.
- a spring preload on the actuating element can be brought about in particular via the clamping leg, which is elastically deflected in the actuated position and, after the actuating element is released, acts on the actuating element in a spring-mechanical manner to transfer the actuating element from the actuated position towards the non-actuated position.
- the connection arrangement closes automatically when the electrical cable is plugged in. This results in a simple connection process, with reliable contact between the electrical cable and the contact element due to the clamping effect of the clamping arm.
- connection arrangement further comprises a line guide arrangement which guides the line to be connected to the trigger element.
- the line guide arrangement enables targeted guidance of the line inserted through the plug-in opening to the trigger element.
- the line guide arrangement is preferably arranged between the plug-in opening and the trigger element.
- the line guide arrangement is positioned substantially closer to the trigger element than to the plug-in opening.
- the line guide arrangement can in particular prevent the line to be connected and in particular the individual strands of the line from moving sideways.
- the line guide arrangement can ensure that all strands of the line to be connected hit the trigger element in order to actuate it.
- the housing defines a receiving space into which the electrical cable can be inserted by inserting it into the plug-in opening.
- the triggering leg extends into the receiving space to interact with the electrical cable.
- the electrical cable can be inserted into the plug-in opening along a plug-in direction, with the triggering leg extending transversely to the plug-in direction in the receiving space.
- the triggering leg can be elastically deflected relative to the support leg of the triggering element, so that when interacting with the electrical cable, the triggering leg is elastically adjusted.
- the trigger arm can be elastically adjusted in the receiving space and extends in the receiving space in such a way that an electrical cable inserted into the plug opening strikes the trigger arm when inserted into the receiving space and thus deflects it.
- the cable guide arrangement is arranged in front of the trigger arm of the trigger element when viewed in the plug-in direction.
- the cable can first come into contact with the cable guide arrangement, so that the cable is brought into the optimal position via the cable guide arrangement in order to guide the cable to the trigger arm of the trigger element and thus to hit the trigger arm of the trigger element.
- the housing can have a first wall surface delimiting the receiving space and a second wall surface delimiting the receiving space, which is opposite the first wall surface, wherein the line guide arrangement can have a first line guide element arranged on the first wall surface and/or a second line guide element arranged on the second wall surface.
- the line guide arrangement can thus be at least partially formed on the housing or be part of the housing.
- At least one line guide element can be arranged on a wall surface.
- the line guide element is then preferably formed in one piece with the wall surface, so that the first and/or second line guide element can be formed from a plastic material in the same way as the housing. If two line guide elements are provided which are arranged on the wall surfaces of the housing, they are preferably arranged opposite one another. The line to be connected can then be guided between the first line guide element and the second line guide element.
- the first line guide element can be designed in the form of a wall projection protruding from the first wall surface and extending into the receiving space and/or the second line guide element can be designed in the form of a wall projection protruding from the second wall surface and extending into the receiving space.
- the wall surface can then be shaped in such a way that it can form a wall projection protruding into the receiving space, which extends from the main extension plane of the respective wall surface.
- the wall projection can, for example, be designed in the shape of a web.
- the first cable guide element can have a run-on surface for the cable to be connected and/or the second cable guide element can have a run-on surface for the cable to be connected.
- the run-on surface can be designed as an inclined surface.
- the run-on surface preferably has an inclination of between 10° and 45° to the main extension plane of the respective wall surface. If the cable guide arrangement has a first cable guide element and a second cable guide element, each of which has a run-on surface, these are preferably shaped in such a way that they run towards one another, so that they form a type of funnel in which the cable to be connected is guided towards the extinguishing arm of the trigger element.
- the second cable guide element can extend from the plug-in opening to the triggering leg, wherein the cable guide element can have a contact surface for the inserted cable from the plug-in opening to the triggering leg.
- the second cable guide element can then have at least one section that extends in the plug-in direction.
- the cable can then lie flat along its length on the second cable guide element, in particular on the section of the cable guide element that extends in the plug-in direction.
- the second cable guide element can, for example, have a bar shape that can extend from the plug-in opening to the triggering leg of the triggering element.
- the cable guide arrangement can preferably have a third cable guide element, which can be formed on the contact element.
- the third cable guide element arranged on the contact element can be positioned between the first cable guide element arranged on the first wall surface and the second cable guide element arranged on the second wall surface.
- These three cable guide elements can enable the cable to be guided on three sides of the cable.
- the clamping leg also serves as a guide for the cable
- the three cable guide elements of the cable guide arrangement together with the clamping leg can be used to achieve 360° guidance of the cable to be connected to the triggering leg of the triggering element.
- the third line guide element has a ramp shape, over which the plugged-in line can be guided to the release leg.
- the line When the line is plugged in, the line can be guided to the release leg over the ramp formed by the third line guide element. Due to the ramp shape, the third line guide element has a sliding surface for the line to be connected, which is inclined to the main extension plane of the contact element and along which the line can slide in the plugging direction when plugged in.
- the housing can be designed in several parts, for example. If the housing is designed in several parts, the housing can have several wall segments, which can be arranged in a row one behind the other and which can be connected to one another, for example, via a plug connection and/or a snap-in connection.
- a receiving space can be formed between two adjacent wall segments, into which a cable to be plugged in can be inserted and connected. The previously described first wall surface and the second wall surface can then be formed on a wall segment.
- a receiving space can then be delimited laterally by a first wall surface of a first wall segment and a second wall surface of an adjacent second wall segment.
- the release arm is locked in a locking position with the actuating element in the actuated position. From the locking position, the release arm can be adjusted to release the actuating element from the actuated position by interacting with the electrical line. The actuating element is thus locked in the actuated position via the release arm. By deflecting the release arm from the locking position, the locking can be released so that the actuating element is released from the actuated position and the clamping arm of the spring element can be adjusted from the release position towards a clamping position.
- the spring element is designed as a tension spring.
- the clamping leg of the spring element is designed to pull the electrical line into contact with the contact element by spring force.
- an opening can be formed on the clamping leg, for example, through which the electrical line can be guided when plugged into the plug opening of the housing in order to pull the electrical line into clamping contact with the contact element after the clamping leg is released from the release position.
- the spring element can be designed as a compression spring.
- the clamping leg is designed to press the electrical cable into contact with the contact element using spring force. When inserted into the plug opening, the electrical cable enters a space between the clamping leg and the contact element, whereby after the clamping leg is released from the release position, the clamping leg acts on the electrical cable and presses it into contact with the contact element.
- the clamping leg can be elastically adjusted relative to the housing by actuating the actuating element into a release position and is held in the release position relative to the housing by the actuating element which is locked in the actuated position. The clamping leg is thus locked in the release position relative to the housing, so that the clamping leg remains in the release position after actuating the actuating element.
- the spring element can, for example, have a support leg, via which the spring element is supported on the housing and held in position on the housing.
- the clamping leg can be elastically deflected relative to the support leg, wherein in the release position the clamping leg is deflected such that the spring element is elastically tensioned and the clamping leg is moved out of the release position in an elastically pre-tensioned manner after being released from the release position.
- the support end of the trigger element is arranged on the support leg.
- the support end can in particular be supported on the support leg, so that torques from the trigger element on the support leg can be absorbed and diverted via the support leg via the support on the support leg of the spring element.
- the support end of the trigger element is thus fixed stationary to the housing via the support leg and is preferably held torque-proof to the housing, wherein the trigger leg extends from the support end and can be elastically deflected towards the support end, in particular by interacting with the electrical cable inserted into the plug opening.
- the trigger element has an opening through which the support leg of the spring element extends. Due to the engagement of the support leg in the opening of the trigger element, the trigger element is arranged in the region of the support end on the support leg and is supported on the support leg, preferably such that when the electrical line acts on the trigger arm, a desired torque is absorbed and supported at the support end and the trigger arm is thus elastically deflected relative to the support end. Due to the elastic deflection, the trigger arm is automatically returned to its original position when the trigger arm no longer interacts with the electrical line, so that when the actuating element is actuated again, a latch is again created in the actuated position of the actuating element and the actuating element can thus be held in the actuated position via the trigger element.
- the actuating element is mounted on the housing so that it can pivot about a pivot axis and has an actuating section for actuation by a user and an active section for acting on the clamping leg. While the actuating section is accessible from outside the housing, for example by a user being able to act on the actuating section using a tool, such as a screwdriver, or alternatively manually, the active section is in active connection with the clamping leg of the spring element. By adjusting the actuating element, an adjusting force is thus exerted on the clamping leg via the active section, so that, in particular when the actuating element is adjusted from the non-actuated position to the actuated position, the clamping leg is taken along and thus moved in the direction of the release position.
- the actuating element can be pivotably mounted on the housing, for example via an axle element, and can thus pivot about the pivot axis relative to the housing.
- the spring element extends around the axle element that supports the actuating element. This means that the spring element, for example via a bending section arranged between the support leg and the clamping leg, reaches around the axle element at an angle of preferably greater than 120°, preferably 150°. This makes it possible to ensure that the spring element is mounted centrally to the pivot axis of the actuating element in such a way that the clamping leg can be deflected essentially centrally to the pivot axis relative to the support leg.
- the pivot point of the actuating element and the pivot point of the clamping leg are therefore at least approximately the same.
- clamping leg can be adjusted in a simple manner by actuating the actuating element, with advantageous force introduction without a change in the position of the actuating element relative to the clamping leg when pivoting.
- the actuating element can be activated by the clamping leg can be easily reset when the locking mechanism is released.
- the actuating element has a through-opening through which the spring element engages.
- the spring element can in particular be formed by a bent sheet metal spring, in which the clamping leg can be deflected along an adjustment plane relative to the support leg.
- the spring element extends through the through-opening of the actuating element, for example around the pivot axis of the actuating element, so that the spring element is supported via the support leg on the housing on a first side of the actuating element and the clamping leg protrudes from the actuating element on a second side facing away and is adjusted together with the actuating element when the actuating element is adjusted.
- the actuating element can have two side surfaces extending parallel to one another and spaced apart from one another along the pivot axis of the actuating element, between which the through-opening is formed so that the through-opening is closed on both sides.
- the spring element reaches through the through-opening and protrudes from the actuating element on a first side with the support leg and protrudes from the actuating element on a second side with the clamping leg.
- the actuating element can also be open on one side, for example by the actuating element having a side surface on one side, but no further side surface spaced apart from this side surface along the pivot axis.
- the access opening is thus open on one side (viewed along the pivot axis).
- the actuating element has a latching section for latching with a latching device of the trigger element in the actuated position.
- the locking section can be arranged, for example, on a side of the actuating element facing away from the actuating section (with reference to the pivot axis of the pivotable mounting of the actuating element on the housing), preferably approximately diametrically opposite the actuating section with reference to the pivot axis.
- the actuating element is locked in the actuated position with an associated locking device of the trigger element via the locking section, so that the actuating element is held in the actuated position by this, but can be released from the actuated position in a simple, reliable manner by triggering the trigger arm when the electrical cable is plugged in.
- the latching device of the trigger element can be formed, for example, by an opening into which the latching section of the actuating element, for example formed by a projection, engages in the actuated position of the actuating element.
- the actuating element is thus held in position in its actuated position by the positive engagement of the latching section in the opening of the trigger element, whereby the engagement can be canceled by adjusting the trigger leg and the actuating element can thus be released from the actuated position to transfer the clamping leg into the release position.
- the opening into which the latching section of the actuating element engages in the actuated position can, for example, be formed on the trigger arm of the trigger element.
- the engagement can be canceled by moving the trigger arm relative to the latching section of the actuating element and thus canceling the latching connection.

- Fig. 10 is another representation of the wall segment shown in Fig. 9 rotated by 180°.
- Fig. 1 and 6 each show an embodiment of a connection arrangement 1, which forms a housing 10 with a plug opening 100 formed therein for inserting an electrical line (not shown here) along a plugging direction E.
- the housing 10 defines a receiving space 101 into which the electrical line with a stripped conductor end is inserted when it is inserted into the plug-in opening 100 along the plug-in direction E.
- the line with the stripped conductor end is located within the receiving space 101 and is electrically contacted via a clamping leg 120 of a spring element 12 with a contact element 11 in the form of a current bar, so that the electrical line is electrically connected to the connection arrangement 1.
- the spring element 12 has a support leg 121 which is supported on a wall of the housing 10, so that the spring element 12 is attached to the housing 10 via this and is fixed to the housing 10.
- the clamping leg 120 can be elastically deflected to the support leg 121, in particular such that the clamping leg 120 in a clamping position clamps onto a electrical line and presses it under elastic prestress into contact with the contact element 11 and thus electrically contacts the line with the contact element 11 via its conductor end.
- an actuating element 14 is pivotably mounted on the housing 10 via a pivot axis 140.
- the actuating element 14 can be pivoted about the pivot axis 140 relative to the housing 10, wherein an actuating section 141 is accessible from outside the housing 10 via an actuating opening 102 and can thus be actuated by a user, for example using a tool.
- the actuating element 14 is operatively connected to the clamping leg 120 of the spring element 12.
- the spring element 12 passes through a through opening within the actuating element 14 such that the spring element 12 engages around the pivot axis 140.
- the support leg 121 protrudes from the opening on a first side and is supported on the housing 10.
- the clamping leg 120 protrudes from the actuating element 14 on a remote, second side and extends within the receiving space 101 in the area of the plug-in opening 100 such that the spring element 12 can act via the clamping leg 120 on an electrical line inserted into the plug-in opening 100 for contacting the contact element 11 and also for mechanical locking.
- the connection arrangement 1 has a trigger element 13, which is arranged via a support end 132 on the support leg 121 of the spring element 12 and is supported by it in a torque-resistant manner relative to the housing 10.
- the support end 132 can also be supported directly on the housing 10, as can be seen in Fig. 6.
- the release leg 130 serves to interact with an electrical line inserted into the plug opening 100, in particular to automatically connect the electrical line to the connection arrangement 1 by releasing the clamping leg 120.
- the trigger element 13 has an opening 131 through which the support leg 121 extends to support the support end 132 relative to the housing 10, as shown in for example, as can be seen in Fig. 1 and 6.
- the actuating element 14 is also locked into the opening 131 via a latching section 143 in the form of a projection when the actuating element 14 has been transferred in an actuating direction B1 into the actuated position shown in Fig. 1 and 6.
- the actuating element 14 engages with the latching section 143 in the opening 131 and is held in a latching manner on the trigger arm 130, so that the actuating element 14 is locked in the actuated position according to Fig. 1 and 6.
- the actuating element 14 takes the clamping leg 120 of the spring element 12 with it via an active section 144 and thereby adjusts the clamping leg 120 into a release position.
- the clamping leg 120 releases an area within the receiving space 101 that is aligned with the plug-in opening 100 along the plug-in direction E, so that an electrical line can be plugged into the plug-in opening 100 without hindrance from the clamping leg 120 and can thus be connected to the connection arrangement 1 in a substantially forceless manner.
- a run-on element 133 is formed by a bent section of the trigger element 13, which is formed as a sheet metal element, onto which the latching section 143 runs when released from the latching. Because the electrical line also acts on the trigger arm 130 with a lever arm that is larger than the lever arm acting on the latching section 143, the trigger arm 130 can be deflected with little force applied by the electrical line and thus the latching can be easily and reliably released when the electrical line is plugged in.
- the actuating element 14 moves out of the actuated position due to the elastic pre-tension on the clamping leg 120 and is returned in an adjustment direction.
- the clamping leg 120 thereby comes into clamping contact with the electrical line and thereby presses the conductor end 20 into contact with the contact element 11, so that the line is electrically connected to the connection arrangement 1 and is also mechanically locked.
- the actuating element 14 can be moved back into the actuated position so that the clamping leg 120 is brought out of contact with the cable.
- the cable can thus be removed from the connection arrangement 1 in a substantially forceless manner.
- the trigger element 13 is preferably supported in a torque-resistant manner relative to the housing 10 via the support end, so that the trigger leg 130 can be elastically deflected towards the support end and can thus automatically return to a relaxed starting position after deflection.
- the trigger element 13 can be designed, for example, as a metal sheet element. However, other designs of the trigger element 13 are also conceivable and possible, for example manufacturing it from plastic.
- connection arrangement 1 has a cable guide arrangement 150.
- the cable guide arrangement 150 is arranged between the plug opening 100 and the triggering leg 130 of the triggering element 13.
- the cable guide arrangement 150 has a first cable guide element 151, a second cable guide element 152 and a third line guide element 156.
- the first line guide element 151 and the second line guide element 152 are formed on the housing 10.
- the third line guide element 156 is formed on the contact element 11.
- the three line guide elements 151, 152, 156 are positioned relative to one another in such a way that they enclose the line to be connected in a U-shape and thereby form a type of guide funnel for the line to be connected.
- the three line guide elements 151, 152, 156 are shaped in such a way that the guide funnel formed thereby tapers towards the release leg 130.
- the cable can be guided upwards through the clamping leg 120, so that the cable guide arrangement 150 together with the clamping leg 120 can form a 360° guide for the cable towards the triggering leg 130 of the triggering element 13.
- the first line guide element 151 is formed on a first wall surface 103 of the housing 10.
- the second line guide element 152 is formed on a second wall surface 104 of the housing 10.
- the line guide elements 151, 152 are located opposite one another, as can be seen in the sectional view of Fig. 2. Starting from the respective wall surface 103, 104, the line guide elements 151, 152 protrude into the receiving space 101.
- the two line guide elements 151, 152 can thus each form a wall projection.
- the two cable guide elements 151, 152 are each formed integrally with the respective wall surface 103, 104, so that the cable guide elements 151, 152, like the wall surfaces 103, 104, can be formed from a plastic material.
- the first line guide element 151 has a web shape, wherein the first line guide element 151 extends transversely to the plugging direction E.
- the second cable guide element 152 extends in the plug-in direction E, as can be seen in Fig. 5, starting from the plug-in opening 100 to the release leg 130, wherein the cable guide element 152 forms a contact surface 155 for the plugged-in cable starting from the plug-in opening 100 to the release leg 140.
- the second cable guide element 152 has a section 157 which extends in the plug-in direction E.
- the cable can then lie flat along its length on the second cable guide element 152, in particular on the section 157 of the cable guide element 152 extending in the plug-in direction E.
- the section 157 of the cable guide element 152 has a bar shape.
- the first guide element 151 has a run-on surface 153 for the line to be connected.
- the run-on surface 153 is designed as an inclined surface.
- the run-on surface 153 has an incline of between 10° and 45° to the main extension plane of the first wall surface 103.
- the second line guide element 152 also has a run-on surface 154.
- This run-on surface 154 is also designed as an inclined surface.
- the run-on surface 154 has an incline of between 10° and 45° to the main extension plane of the second wall surface 104.
- the housing 10 is made up of several parts.
- the housing 10 here has several wall segments 105A, 105B, 105C, 105D.
- the wall segments 105A - 105D are arranged in a row one behind the other.
- Wall segments 105A - 105D arranged adjacent to one another are connected to one another via a plug connection or a snap connection.
- the wall segments 105A - 105D fastened to one another are enclosed by a housing casing 106.
- the individual wall segments 105A - 105D are each connected to the housing casing 106, preferably detachably.
- first wall surface 103 and the second wall surface 104 are formed on the wall segments 105B, 105C, wherein the first wall surface 103 can be formed on a front side of the wall segment 105B, 105C and the second wall surface 104 can be formed on a rear side of the wall segment 105B, 105C.
- Two wall segments 105A - 105D arranged adjacent to one another each form a boundary for a receiving space 101.
- Three receiving spaces 101 are formed in the housing 10, in each of which a line can be connected.
- a receiving space 101 is delimited by the wall segment 105B and the wall segment 105C.
- the line guide arrangement 150 is formed here by the first line guide element 151 on the first wall surface 103 of the wall segment 105C and by the second line guide element 152 on the second wall surface 104 of the wall segment 105B.
- the third line guide element 153 is formed on the contact element 11, as can be seen in Fig. 3, for example.
- the third line guide element 153 has a ramp shape, over which the plugged-in line is guided to the release leg 130.
- the line When the line is plugged in, the line can be guided to the release leg 130 via the ramp formed by the third line guide element 153. Due to the ramp shape, the third line guide element 130 has a sliding surface for the line to be connected, which is inclined to the main extension plane of the contact element 11 and along which the line can slide in the plugging direction E when plugged in.
- the cable guide arrangement 150 has only two cable guide elements 151, 152 and no third cable guide element 153.
- the first and second cable guide elements 151, 152 also have the same shape, so that the two cable guide elements 151, 152 formed on the two wall surfaces 103, 104 are formed essentially symmetrically to one another, as can be seen in Fig. 7 to 10.
