Description

Connector device with at least one fixing part for providing a strain relief or jacket fixation

The invention relates to a connector device according to the preamble of claim 1.

Such a connector device comprises a base body which can be inserted, for example, into an opening in a wall and has a wall section and an insertion opening formed therein and extending along a longitudinal axis. An electrical cable can be inserted into the base body along the longitudinal axis via the insertion opening.

Such a connector device can, for example, provide a connector for establishing an electrical connection. Such

Connector device can be used, for example, in the field of photovoltaics in order to produce an electrical plug connection on a photovoltaic system.

Such a connector device can be, for example

Realize wall bushing device and serve to lead an electrical connection through a wall, for example a control cabinet. For this purpose, the connector device can form a connector on one side of the wall, to which an electrical line is led on the other, opposite side of the wall, so that an electrical connector is provided on the wall by means of the connector device.

In such a connector device, an electrical cable is arranged on the base body and, for example, also fixed in relation to a wall to which the base body is attached. Such a cable is inserted into the insertion opening for connection to the base body and is inside the base body, for example with an electrical contact element through the

Connector device trained connector contacted.

When connecting the cable to the base body, care must be taken to ensure that the cable is firmly and securely attached to the base body. A strain relief or fixation for a cable jacket and conductor insulation, which can absorb tensile forces acting on the cable and introduce it into the base body without the cable being able to detach from the base body, is particularly desirable.

2018/5764

BE2018 / 5764

Without such strain relief, there is a risk, for example, that the insulation of the cable could shift, which can result in the air and creepage distances that may be required no longer being maintained.

In a holding device for a cable known from DE 10 2014 001 161 A1, a receiving part can be connected to a hold-down device in order to enclose a cable between the receiving part and the hold-down device.

In a strain relief known from DE 10 2015 112 045 A1, a cover part can be attached to a base part in order in this way to fix a cable to a housing.

DE 197 51 175 C2 discloses a cable clamp with two clamp halves that can be screwed together.

The object of the present invention is to provide a reliable strain relief or fixation for a cable sheath for a cable on a connector device that can be produced in a simple manner.

This object is achieved by an object with the features of claim 1.

Accordingly, the connector device has a fixing device which has at least one fixing part to be arranged on the base body, the at least one fixing part being firmly connectable to a cable arranged on the wall section of the base body and the base body having a first guide device arranged on the wall section and the at least one Fixing part have a second guide device. The first guide device and the second guide device can be brought into engagement with one another in such a way that the at least one fixing part can be displaced on the wall section along an assembly direction directed transversely to the longitudinal axis, but is held in a form-fitting manner on the wall section along the longitudinal axis.

A strain relief for a cable on the base body of the connector device is made available via the fixing device. The fixing device has one or more fixing parts which are to be fastened to the wall section of the foundation body. The at least one fixing part is connected to the base body in a load-bearing manner and can be fixed to the cable in this way,

2018/5764

BE2018 / 5764 that a strain relief or fixation for a cable sheath for the cable relative to the base body is provided via the fixing part.

Guide devices which can be brought into engagement with one another are used to fasten the at least one fixing part to the base body, in order in this way to arrange the at least one fixing part on the wall section of the base body. The fastening of the at least one fixing part to the base body is such that the at least one fixing part can be displaced along a mounting direction on the wall section of the base body, so that the position of the at least one fixing part on the wall section can be adjusted relative to the cable. The cable extends into the insertion opening formed in the wall section. By moving along the direction of assembly, the at least one fixing part can thus be brought into operative connection with the cable, in order in this way to fix the cable in a load-bearing manner relative to the base body.

The engagement of the guide devices with one another is such that the at least one fixing part can be moved in a guided manner along the mounting direction on the wall section of the base body. Axially along the longitudinal axis, a positive connection is created between the base body and the at least one fixing part via the guide devices, so that tensile forces acting on the cable can be introduced into the base body via the fixing part and can be derived therefrom.

The fixing device thus provides a flexibly adaptable, easy-to-install strain relief or fixation for a cable sheath for a cable on the base body. By moving the at least one fixing part along the mounting direction on the wall section, the fixing device can in particular be adapted to cables with different cable diameters, so that very differently dimensioned cables can be fixed to the base body via the fixing device.

In one embodiment, the first guide device and the second guide device jointly form a dovetail guide, via which the at least one fixing part is guided along the mounting direction on the wall section and is held in a form-fitting manner on the wall section along the longitudinal axis. Such a dovetail guide creates a strong connection along the longitudinal axis. Moving the at least one fixing part on the

2018/5764

BE2018 / 5764

Wall section of the base body along the assembly direction extending transversely to the longitudinal axis is, however, possible in a guided manner.

In one configuration, the first guide device or the second guide device have at least one guide groove extending along the mounting direction. In contrast, the other guide device in each case has a guide web which can be brought into engagement with the guide groove in order in this way to define a guide between the at least one fixing part and the wall section of the base body along the installation direction. Along the mounting direction, the at least one fixing part can be displaced to the base body via the engagement of the guide web in the guide groove in order in this way to flexibly adjust the position of the fixing part in relation to a cable arranged on the base body.

Different configurations of such a fixing device are conceivable and possible. Such a fixing device can in particular have one fixing part or also several fixing parts.

In one configuration, the fixing device has two fixing parts which can be attached to one another along the assembly direction directed transversely to the longitudinal axis and which are connected to one another in a position attached to one another, for example in a latching manner. The fixing parts can in particular be attached to one another in such a way that they receive a cable to be fixed to the base body between them and above that fix the cable relative to the base body. By attaching the fixing parts to each other, the fixing parts are brought into contact with the cable, so that the cable is fixed to the fixing parts. Due to the fact that each fixing part is fixed in a guided manner via a respectively assigned second guide device on an assigned first guide device of the wall section of the base body, tensile forces acting axially on the cable can be introduced into the base body via the fixing parts and can be derived in this way.

The fixing parts each have, for example, a contact surface with which the fixing parts, when they are attached to one another, can be brought into clamping, non-positive contact with a cable received between the fixing parts. The contact surface can be curved around the longitudinal axis. Active elements can be on the contact surface, for example in the form of webs extending axially along the longitudinal axis or circumferentially around the longitudinal axis, in the form of a corrugation or also in the form of a

2018/5764

BE2018 / 5764

Toothing be arranged. A firm, resilient connection between the fixing parts and a cable accommodated between the fixing parts can thus be established via the contact surface.

The fixing parts are preferably designed as identical parts. This enables simple assembly and storage, in which, in particular, it does not have to be observed that two matching but different fixing parts are always used on a base body for assembly. Rather, two arbitrary fixing parts can be gripped from a reservoir of (identical) fixing parts and attached to one another along the mounting direction, in order in this way to fix a cable to the base body.

The design of the fixing parts as identical parts has the further advantage that the fixing parts are easy to manufacture, for example by means of plastic injection molding in an injection molding tool. In particular, only a single tool has to be provided in which fixing parts of identical design are manufactured as identical parts.

In one configuration, the fixing parts each have a base, a first leg extending from the base and a second leg extending from the base. The fixing parts can each have a U-shaped basic shape, the fixing parts can be attached to one another via their legs and, when the fixing parts are attached to one another, a cable to be fixed is received between the legs.

In one configuration, the first leg of each fixing part has two leg elements which are axially offset from one another along the longitudinal axis and are separated from one another by a slot opening. Via such a slot opening formed between the leg elements, in particular an axially secured connection between the fixing parts can be created by an associated form-locking element of the other fixing part engaging in the slot opening of each fixing part when the fixing parts are attached to one another and take up the cable between them.

The second leg of each fixing part can, for example, have an outer leg wall and an inner leg wall, which, viewed along a transverse direction transverse to the longitudinal axis, form an intermediate space between them

2018/5764

BE2018 / 5764 and thus spaced apart from one another along the transverse direction. In this case, the first leg of the other fixing part can engage in the intermediate space when the fixing parts are attached to one another, so that in this way a connection between the first leg of each fixing part and the second leg of the respective other fixing part is established.

A form-locking element in the form of a web section dividing the intermediate space can be formed in the intermediate space, which serves to engage the slot opening formed between the leg elements of the first leg when the fixing parts are attached to one another, in order in this way to provide a positive fit for axially fixing the fixing parts to one another to manufacture. The land portion extends along the mounting direction in the space and connects the outer leg wall and the inner leg wall of the second leg to one another along the transverse direction, the land portion dividing the space between the outer leg wall and the inner leg wall into two halves, each of which is formed to take up a leg element of the first leg of the respective other fixing part.

In one configuration, the first leg has a first toothed section and the second leg has a second toothed section. When the fixing parts are attached to one another for assembly, the first toothed section of each fixing part engages with the second toothed section of the other fixing part along the assembly direction, so that a latching connection between the fixing parts is produced in this way.

The first toothed section and the second toothed section can each be sawtooth-shaped in such a way that the fixing parts can be attached to one another in the assembly direction when the toothed sections slide ratchetly over one another. A loosening of the fixing parts against the mounting direction is blocked by engagement of the first toothing section and the second method section, so that the fixing parts cannot be removed from one another counter to the mounting direction, at least not without loosening the locking connection.

The toothed sections can each be formed by a sequence of teeth strung together, for example in the form of saw teeth. However, it is also conceivable and possible for a toothed section to be made up of only one tooth

2018/5764

BE2018 / 5764 is formed, for example a single saw tooth, which interacts with teeth of the other toothing section.

To connect the fixing parts to the cable, the fixing parts can thus be attached to one another along the mounting direction and engage with one another in a latching manner. The fixing parts can be pressed towards each other for a firm connection with the cable, but a counter movement against the mounting direction is blocked by the toothed sections, so that the fixing parts are held securely and reliably in position on the cable.

Due to the fact that the fixing parts for connecting with a cable are attached to one another along the mounting direction and thereby moved towards one another, it is possible in a flexible manner to receive cables of different cable diameters between the fixing parts and thus to fix them to the base body. In the case of a cable with a comparatively large cable diameter, the fixing parts are attached to one another and connected to one another in a snap-in manner, so that they come into clamping contact with the cable. In contrast, in the case of a cable with a smaller cable diameter, the fixing parts can be moved further towards one another until they come into contact with the smaller dimensioned cable. In each case, a clamping, non-positive, resilient connection of the cable with respect to the base body can be established via the fixing parts, in that the fixing parts are fixed to one another axially along the longitudinal axis on the base body via the engagement of the guide devices.

In another embodiment of the fixing device, only a single fixing part is provided, which is used to fix a cable to the base body. Such a fixing part can have, for example, a base and a cable fixing arranged on the base, for example in the form of a cable tie, for fixing the cable to the base. For example, using a cable tie, in which ends can be placed around a cable to be fixed and connected to one another via a connecting device, the cable can be fixed to the base in a load-bearing manner for absorbing axial tensile forces, the base via the engagement of the guide devices fixed in one another on the base body of the connector device and thus held axially loadable on the base body.

2018/5764

BE2018 / 5764

In one configuration, the connector device has a fastening device which can be attached to the base body in order to fasten the base body to a wall, for example of a control cabinet. The fastening device serves to fix the base body to the wall, for example, in that the wall is clamped between a collar of the base body and the fastening device. The base body of the connector device can be used for arrangement and fixing on a wall, for example the wall of a control cabinet, for example in an opening in the wall, wherein an electrical line can already be connected to the base body or can be passed through the base body. To fix the base body to the wall, the fastening device is attached to the base body which extends through the opening of the wall.

In one embodiment, the base body has a collar and a shaft projecting axially from the collar along the longitudinal axis. The fastening device can be attached to the shaft in such a way that the wall is accommodated between the collar and the fastening device in a position of the fastening device attached to the shaft. The collar thus serves, in cooperation with the fastening device, to establish a clamping connection between an assigned wall and the connector device. When the base body is attached to an associated wall, the collar comes to rest on a first side of the wall, while the fastening device is connected to the shaft of the base body on a second side of the wall facing away from the first side. The wall thus comes into an intermediate position between the collar and the fastening device, so that by attaching and fixing the fastening device to the shaft, the connector device can be connected to the wall by clamping.

In one embodiment, the fastening device can be designed as a wedge. Such a wedge can, for example, be attached to the shaft of the base body along a fastening direction directed obliquely to the longitudinal axis, in order in this way to fix the wedge to the base body and above that to fix the base body with respect to the wall to which the base body is attached.

Such a fastening device in the form of a wedge can be guided on the base body, for example, via guide edges along the fastening direction extending obliquely to the longitudinal axis. The fastening device can thus be defined

2018/5764

BE2018 / 5764

Be attached to the base body and moved to the base body in order to bring the fastening device in the form of the wedge into contact with the wall and to fix the base body to the wall.

Because the fastening device can be attached to the shaft of the base body without threading the cable through the fastening device, the base body can be connected, for example, to an electrical line in advance for assembly. After the base body has been attached to an associated wall, the base body can then be fixed by attaching the fastening device to the wall, in that a clamping connection is established between the base body and the wall using the fastening device.

In one configuration, the fastening device has a head section and two fastening legs extending from the head section. The fastening legs preferably each have a wedge shape and are connected to one another via the head section, so that an approximately U-shaped component results in cross section. On the shaft of the base body, two flanks are formed on opposite sides of the base body, with which the fastening legs of the fastening device can be brought into contact and to which the fastening device can be fastened via the fastening legs.

At least one of the flanks of the base body preferably has a first latching device and at least one of the fastening legs of the fastening device has a second latching device. The latching devices can, for example, each be designed as toothing and can be moved in a ratcheting manner along the fastening direction, so that the fastening device can be attached to the base body in the fastening direction. By engaging the locking devices into each other

Fastening device held on the base body when the

Fastening device has been brought into contact with the wall to which the base body is attached.

The latching devices can each have, for example, a sawtooth shape which enables the fastening device to be moved in the fastening direction to the base body in order to bring the fastening device into contact with the wall on the base body. A movement is against the direction of attachment

2018/5764

BE2018 / 5764, however, is prevented by the sawtooth shape of the latching devices, so that the fastening device is held securely and reliably in position for the clamping connection of the base body to the wall.

In one embodiment, a sealing element can be arranged on the collar, which serves to seal the base body against the wall when the base body is fixed to the wall via the fastening device. The sealing element can be arranged on one side of the collar, which (viewed along the longitudinal axis) faces the wall, so that when the base body is attached to the wall, the sealing element comes into contact with the wall and thus a transition between the collar and the wall seals moisture-proof.

In one configuration, the base body has a plug connector with a plug section that can be plugged in with an associated mating plug connector part. Such a connector can be used, for example, to establish an electrical connection. For example, an electrical line can be connected to the plug connector via the shaft of the base body, an electrical contact element being arranged on the plug section, via which electrical contacting with an associated mating contact element of the

Mating connector part can be manufactured.

The plug-in section can in particular be arranged on an end of the base body facing away from the wall portion of the base body on which the at least one fixing part is to be arranged. The plug-in section can extend along the longitudinal axis and can be designed for plug-in connection with a mating connector part in a plug-in direction directed along the longitudinal axis.

Such a connector device and a connector designed on the connector device can be used in particular in the field of photovoltaics, for example for providing a plug connection on a photovoltaic system, for example on a control cabinet of a photovoltaic system. However, this is not limitative. A connector device of the type described can in principle be used wherever a bushing through a wall, for example a control cabinet, is to be provided.

A connector device 1 shown in an exemplary embodiment in FIGS. 1 and 2 in the form of a wall bushing has a base body 2, which can be fixed to a wall 4, for example of a control cabinet, in order in this way to connect a connector 21 formed on the base body 2 to the Attach wall 4.

As can be seen from FIGS. 1 and 2 in conjunction with the separate representations of the base body 2 according to FIGS. 15A and 15B, the base body 2 has a shaft 20 extending along a longitudinal axis L and an insertion opening 22 formed in the shaft 20 for inserting an electrical cable 5 on.

2018/5764

BE2018 / 5764

The plug connector 21 is formed on an end of the base body 2 facing away from the shaft 20 and has a plug section 210 for the plug-in connection with an associated mating plug connector part 6 (shown schematically in FIG. 2).

Latching elements on both sides of the plug-in section 210 form a latching device 211, by means of which, when plugged in with the associated mating connector part 6, a latching, form-fitting connection between the plug connector 21 and the assigned mating connector part 6 can be produced.

A collar 23 is arranged axially between the plug connector 21 and the shaft 20, which projects radially opposite the shaft 20 and serves to come into contact with the wall 4 when the base body 2 with its shaft 20 into the opening 40 of the wall 4 is used. In one embodiment, a seal 25 is arranged on the collar 23, which serves to seal a transition between the collar 23 and the wall 4 in a moisture-tight manner.

To mount the connector device 1 on an assigned wall 4, the base body 2 is inserted with its shaft 20 into an assigned opening 40 in the wall 4 such that the shaft 20 extends through the opening 40 and the collar 23 on one of the shaft 20 opposite side of the wall 4 comes to rest, as can be seen from FIG. 2. The base body 2 can then be attached to the shaft 20 to the wall 4 by attaching a fastening device (for example designed as will be explained below using the exemplary embodiment according to FIGS. 19 to 21).

The connector device 1 has a fixing device 3, which serves to fix an electrical cable 5 connected to the base body 2 relative to the base body 2 and in particular to provide a strain relief for the cable 5 relative to the base body 2. In the exemplary embodiment shown in FIGS. 1 and 2, the fixing device 3 has two fixing parts 30, which can be attached to one another along a mounting direction M extending transversely to the longitudinal axis L and, in an attached position, accommodate the cable 5 between them. The fixing parts 30 are connected to the base body 2 in such a way that the fixing parts 30 provide strain relief for the cable 5 relative to the base body 2.

Different views of the connector device 1 with the fixing parts 30 are shown in FIGS. 3 to 5A, 5B. 6 to 9A, 9B show the connector device 1

2018/5764

BE2018 / 5764 when used on a cable 5 with a smaller cable diameter. 10 to 12 show fixing parts 30 of different variants in separate representations. 13 to 15A, 15B show the fixing parts 30 and the base body 2 with guide devices 24, 34 each formed thereon for connecting the fixing parts 30 to the base body 2, which connection can be moved along the mounting direction. And FIG. 16 shows the fixing parts 30 together with one on one of the fixing parts 30 to be arranged marking element 35.

The fixing parts 30 of the fixing device 3 are, in the embodiment according to FIGS. 1 to 16, designed as identical parts. Each fixing part 30 has a base 31, a first leg 32 and a second leg 33. The legs 32, 33 together with the base 31 form an approximately U-shaped component, as can be seen, for example, from FIG. 10, the cable 5 when the fixing parts 30 are attached to the cable 5 in an intermediate space between the legs 32 , 33 of the two fixing parts 30 is received, as can be seen, for example, from FIGS. 3 and 4 in conjunction with the sectional view according to FIG. 5B.

The first leg 32 of each fixing part 30 is designed for plug-in connection with the second leg 33 of the respective other fixing part 30. The first leg 32 is formed here by two leg elements 320, which are separated from one another by a slot opening 321 extending along the mounting direction M. The leg elements 320 are lined up axially along the longitudinal axis L and each carry a toothing section 322 in the form of a toothing formed by saw teeth at the transition to the base 31.

The second leg 33 of each fixing part 30 is formed by an outer leg wall 330 and an inner leg wall 331 arranged radially inside the outer leg wall 330. The outer leg wall 330 and the inner leg wall 331 form an intermediate space 332 between them, which is divided into two subspaces by a central web section 334 (see FIG. 10) which extends between the outer leg wall 330 and the inner leg wall 331 and is oriented along the mounting direction M. is divided.

On the outer leg wall 330, in the region of an end remote from the base 31 and on the side of the outer leg wall 330 facing the intermediate space 332, there is a toothing section 333 in the form of a saw tooth

2018/5764

BE2018 / 5764 formed teeth, as can be seen in particular from Fig. 5B and Fig. 11 and 12.

When the fixing parts 30 are placed against one another, the first leg 32 of each fixing part 30, with its leg elements 320, comes into engagement with the intermediate space 332 of the second leg 33 of the respective other fixing part 30 such that the web section 334 dips into the slot opening 321 between the leg elements 320 and the fixing parts 30 are thus fixed to one another along the longitudinal axis L.

When plugging in, the toothed sections 322 on the outside of the leg elements 320 of the first leg 32 of each fixing part 30 come into engagement with the toothed sections 33 on the inside of the outer leg wall 330 of the second leg 33 of the other fixing part 30, as can be seen in particular from the sectional view according to FIG. 5B can be seen, so that a positive connection between the fixing parts 30 is produced. In the mounting direction M, the toothed sections 322, 333 can slide over one another and be moved in a ratchet manner so that the fixing parts 30 can be brought closer to one another in the mounting direction M and brought into engagement with the cable 5, as can be seen from FIGS. 3 and 5B .

The leg elements 320 are so elastic that they can be deflected (slightly) transversely to the mounting direction M when plugged in, so that the leg elements 320 with their toothed sections 322 over the

Gearing sections 333 can ratchet on the inside of the assigned outer leg wall 330 of the respective other fixing part 30. As can be seen from FIGS. 5B and 9B, the leg elements 320 lie here with foot sections 324 on the inner leg wall 331 of the respective other fixing part 30, so that the leg elements 320 are supported on the inner leg wall 331 and the toothing sections 322, 333 engage above them are held together when the fixing parts 30 are connected together.

Due to the engagement of the toothed sections 322, 333 in one another, a counter-movement against the mounting direction M is blocked. Contrary to the mounting direction M, the fixing parts 30, if they are arranged on the cable 5, cannot be removed from one another easily, at least not without releasing the latching connection.

BE2018 / 5764

The insertion opening 22 is formed on an end wall section 200 of the shaft 20 of the base body 2 facing away from the plug connector 21. A cable 5 for connection to the base body 2 is inserted into the shaft 20 via the insertion opening 22. The fixing parts 30 are to be arranged on the wall section 200 in order to connect the fixing parts 30 to the base body 2 and to provide a strain relief for the cable 5 relative to the base body 2.

Each fixing part 30, as can be seen from FIGS. 13 and 14, has guide devices 340, 341 in the form of dovetail-shaped on a side 313 facing the wall section 200 of the base body 2

Leaders on. In the area of each leg 32, 33 there is one

Guide device 340, 341 attached to the base 31, the

Guide devices 340, 341 in the form of the guide webs are extended longitudinally along the mounting direction M in order to provide a guide along the mounting direction M.

The guide devices 340, 341 of the fixing parts 30 serve to engage in complementary guide devices 240, 241 in the form of guide grooves on the wall section 200 of the shaft 20 of the base body 2. The guide devices 240, 241 provide guide tracks which are directed along the mounting direction M and are complementary to the Guide devices 340, 341 in the form of the guide webs are dovetail-shaped, so that, as can be seen in particular from FIG. 13, a guided, form-fitting engagement between the guide devices 340, 341 in the form of the guide webs on the fixing parts 30 and the guide devices 240, 241 in the form of the There are guide grooves on the wall section 200. Via this engagement, the fixing parts 30 can each be displaced along the mounting direction M to the wall section 200 and can be moved towards one another in particular for attachment. Via the engagement, the fixing parts 30 are also positively connected axially along the longitudinal axis L to the base body 2, so that axial tensile forces are introduced into the base body 2 and strain relief for the cable 5 can thus be provided.

As can be seen from FIGS. 15A, 15B, the guide devices 240, 241 on the wall section 200 each have, in their central region, a delimiting section 243 which projects transversely inwards into each guide device 240, 241. Via the limiting section 243 is the adjustment path over which the fixing parts 30 in the

2018/5764

BE2018 / 5764

Guide devices 240, 241 can be moved towards one another in the form of the guide grooves.

Securing elements 242 in the form of protruding, raised latching elements are also arranged on both sides of the guide device 240 on the wall section 200. Via these securing elements 242, the fixing parts 30 are held captively in the guide devices 240, 241, so that the fixing parts 30, when they are inserted into the guide devices 240, 241, are prevented from coming out of the

Guide devices 240, 241 can slide out.

To attach a cable 5 to the base body 2, the cable is inserted into the insertion opening 22, optionally with a contact element pre-assembled thereon. The fixing parts 30 can already be inserted into the guide devices 240, 241 (but not yet locked together) or can only be attached to the guide devices 240, 241 after the cable 5 has been attached. In order to provide the strain relief, after connecting the cable 5, the fixing parts 30 are then moved towards one another in the mounting direction M until they come into contact with the cable 5 with a concave curved contact surface 310 which is formed on the inside of the base 31, as shown in FIG. 1 and 2 and Fig. 6 for cables of different cable diameters can be seen.

Depending on the cable diameter, the fixing parts 30 are pressed together so far that the cable 5 is firmly received between the fixing parts 30. Depending on the cable diameter, the fixing parts 30 assume different positions relative to one another (compare in particular FIG. 1 in comparison to FIG. 6), the fixing parts 30 each being firmly locked together via their legs 32, 33.

The adjustment path of the fixing parts 30 to one another along the mounting direction M, and thus the minimum cable diameter of a cable 5 that can be fixed via the fixing device 3, is defined on the one hand via the limiting sections 243 on the guide devices 240, 241 on the wall section 200 of the base body 2 and on the other hand via the fixing parts 30 trained stops 323, 335 on the legs 32, 33, which rest on one another with a minimally permitted cable diameter and thus define a maximally approximated position of the fixing parts 30 relative to one another, as can be seen, for example, from FIGS. 7 and 8.

2018/5764

BE2018 / 5764

The cable 5 is fixed between the fixing parts 30 via the contact surface 310 on the inside of the respective base 31. For resilient fixing, active elements 311 can be formed on the contact surfaces 310 of the fixing parts 30, for example in the form of inwardly projecting webs, as can be seen for two different variants in FIGS. 11 and 12. Such active elements 311 can extend axially along the longitudinal axis L, as in the variant according to FIG. 11. Alternatively, such webs 311 can also extend along a circumferential direction around the longitudinal axis L, as in the variant according to FIG internally projecting webs 311 can in this case be chosen in any desired manner depending on a desired strength for establishing the operative connection between the fixing parts 30 and the cable 5.

When the fixing parts 30 are attached to one another along the mounting direction M, the guide devices 340, 341 in the form of the guide webs on the fixing parts 30 in the guide devices 240, 241 in the form of the guide grooves on the wall section 200 move, so that the fixing parts 30 move in a defined, guided manner until they are in contact with cable 5. In the case of a pressing system, the active elements 311 in the form of the webs dig into the insulating conversion of the cable 5, for example, so that a frictional connection between the cable 5 and the fixing parts 30 is brought about in this way.

Such active elements 311 can also be designed differently, for example in the form of corrugation or toothing.

3, arrows are attached to the outside of the fixing parts, which serve to indicate to a user the mounting direction M, in which the fixing parts 30 are to be attached to one another for establishing the connection.

Each fixing part 30 has, on an outside of the base 31 facing away from the contact surface 310, a receiving device 312 in the form of a latching recess into which a marking element 35 can be inserted, as can be seen from FIG. 16. The marking element 35 represents a marking plate on which information relating to the connector 21 can be displayed.

In the exemplary embodiments according to FIGS. 1 to 15, the fixing device 3 is formed by two fixing parts 30 which can be attached to one another along the mounting direction M. In an exemplary embodiment shown in FIGS. 17 and 18, the

2018/5764

BE2018 / 5764

Fixing device 3 is formed by only a single fixing part 30, which has a base 31 and a cable fixing 36 arranged thereon in the form of a cable tie. The fixing part 30 is connected to the base 31 via guide devices 340, 341

Guide devices 240, 241 to be arranged on the wall section 200 of the shaft 20 of the base body 2 and can be displaced along the guide devices 240, 241 in order to bring the fixing part 30 into contact with the cable 5 along the mounting direction M and to provide this via the cable fixation 36 a strain relief.

In the exemplary embodiments according to FIGS. 1 to 5 and FIGS. 17 and 18, parts of comparable function are provided with the same reference symbols.

The cable fixation 36 is in particular formed by two ends 360, 361, which are placed around the cable 5 and can be connected to one another via a connecting device 362, as can be seen in FIG. 17 and as is known from a cable tie.

The connector device 1 is to be fixed with its base body 2 to a wall 4 in order to provide a connector 21 on the wall 4. To fix it to the wall 4, the base body 2 is inserted into an opening 40 in the wall 4 and then fixed to the wall 4 via a fastening device.

A fastening device 26 shown in an exemplary embodiment in FIGS. 19 to 21 is designed as a U-shaped component, with a head section 260 and fastening legs 261, which are connected to one another via the head section 260. With the fastening legs 261, the fastening device 26 can be attached to the flanks 201 of the shaft 20 of the base body 2 in order in this way to fix the fastening device 26 on the base body 2.

The fastening device 26 has a wedge shape on its fastening legs 261. In particular, guide edges 263 are formed on the fastening legs 261, which are slidably guided on the associated guide edges 203 on the flanks 201 of the shaft 20 of the base body 2 along a fastening direction K directed obliquely to the longitudinal axis L.

2018/5764

BE2018 / 5764

By moving in the fastening direction K, the fastening device 26 can be brought into contact with the wall 4 via the clamping edges 264 formed on the front side of the fastening legs 261, the base body 2 being able to be flexibly fastened to walls 4 of different thicknesses via the fastening device 26, as shown in FIG. 19 and 20 can be seen.

To fix the base body 2 to the wall 4, the fastening device 26 is pushed onto the shaft 20 in the fastening direction K until the clamping edges 264 come into clamping contact with the wall 4 and the wall 4 is thus held clamped between the collar 23 and the fastening device 26 is.

On the inside of the fastening legs 261, a latching device 262 is formed in the form of a sawtooth-shaped toothing, which can be brought into engagement with a latching device 202 in the form of a sawtooth-shaped toothing on the respectively assigned flank 201 of the shaft 20. Due to the sawtooth shape, a movement of the fastening device 26 in the fastening direction K to the flanks 201 is possible, but a countermovement against the fastening direction K is blocked, so that the fastening device 26 is held reliably and resiliently in its position on the shaft 20 and the wall 4 reliably and is resiliently clamped between the collar 23 and the fastening device 26.

Because the fastening device 26 can be attached to the base 20 after connecting the cable 5 to the base body 2 and after arranging the base body 2 on the wall 4, it is not necessary to close the cable 5 through the fastening device 26 before connecting it to the base body 2 thread as would be required using a nut. This makes it possible to prefabricate components on the cable 5.

The idea on which the invention is based is not limited to the exemplary embodiment described above, but can in principle also be implemented in a completely different manner.

A connector device of the type described here can be used, for example, on a photovoltaic system, for example in order to arrange a connector on a wall of a control cabinet. However, this is not limitative. Basically, a connector device of the here

2018/5764

BE2018 / 5764 described type can be used wherever a bushing to provide a connector is to be provided.
