Description

TECHNICAL AREA

The invention relates to the field of plug-in systems based on plug-in base for a load-free installation and removal of protective devices and additional components under voltage.

STATE OF THE ART

Plug-in socket-based plug systems are used to attach protective devices to the plug-in system in a quick and simple manner, thereby avoiding expensive electrical contacting of the feed-in. In EP 0 229 590 is such a plug-in system described. The plug-in system typically has three main busbars, a neutral conductor and two auxiliary busbars. Different protection devices such. B. Circuit breaker and accessories can be plugged onto such a plug-in system.

Out EP 0 735 916 A2 is also known such a plug-in system. This plug-in system has a lower part, are arranged on the busbars. The busbars are contacted by an adapter part which is hung on a pivot point on the lower part and is then tilted onto the lower part. The adapter part is locked by a latching nose, which engages in a further latching nose in the lower part. On the adapter part a cover plate is placed, in which circuit breakers are clamped. On the adapter part there is also a micro switch, which is closed as soon as the adapter part is folded onto the lower part. Only the switch ensures that the adapter part can not be removed under load.

However, in addition to the lower part on which the busbars are located, the adapter part must also have electrical contacts and the microswitch and lines, since the contacting of the switches takes place on the adapter part. Thus, the system includes a variety of electrical parts and a variety of components, which has a negative impact on the susceptibility and cost of the system. The contact protection is at best given during operation. If the adapter part is removed for assembly, the busbars are open and there is a risk for the installer to come into contact with the live busbars, so that the legally prescribed organizational measures and the Personal Protective Equipment (PPE) must be used for such work ,

The adapter part also has large openings, in each of which the contacts are completely inserted, thus there is an increased risk of direct contact by the installer. Therefore, there is a danger of contact if only the cover plate is removed and thus the microswitch located on the adapter plate is still closed.

Another known from the prior art plug-in system contains busbars on which plates can be attached as contact protection of electrically insulating material to cover unused slots of the system and thus make safe to touch. Like the protection devices, these plates are plugged onto the slots in the same way but as an alternative to them and can occupy one or more slots. Disadvantage of this system is that the operation of the system with or without the insulating plates is possible without the system recognizes this, and thus no secure contact protection is present because the system does not recognize whether there are still free slots. In addition, the insulation must be assigned according to the number of free slots, so insulation panels of different widths be available. During the replacement of a protective device, these insulating plates no longer provide protection since, after removal of a protective device, open contact surfaces with the busbars are present in its place.

However, the availability requirements for electrical supply are increasing. More and more maintenance and extension work on low-voltage installations under tension and time pressure must be carried out in order to keep the unavailability times small (banks, insurance companies, telecommunications airports, ..).

Such systems have the disadvantage that the plates, which are to ensure contact protection, are easy to remove, so that a technician who works on the system can easily remove the protection and then come into contact with live parts. It is also possible to mount the protective devices without protection, so that the plates do not offer any secure protection.

The EP 2461440 A2 discloses a plug-in socket-based plug-in system that provides a touch guard for an operator that provides IP XXB protection during operation of the plug-in system, but also during maintenance, repair, or expansion of the plug-in system. To ensure that work on the busbars are only possible in a de-energized state, the plug-in system according to EP 2461440 A2 has an upper part which can be latched or screwed into a lower part such that the upper part exclusively from the underside of the plug-in system of the lower part is solvable.

All these connector systems have in common that they should be able to adapt as flexibly as possible to the changing needs of their users in the course of their lives. Such an adaptation can be, for example, that an existing distribution system should be equipped with additional components and protection devices. Since the space available for expansion is often tight, in such space the existing plug-in system or socket system in its longitudinal axis defined by its design is usually not extended arbitrarily. As a result, attempts are made in such cases to enlarge the plug-in system in its width extending transversely to the longitudinal axis. Such an extension was made, for example, by the fact that the additional components and protection devices are simply applied to a separate DIN rail, an auxiliary structure or even a second plug-in system.

To counter this problem suggests the EP 0753916 A2 To make the plug-in system in the transverse direction to the longitudinal direction so wide that the additional components and protective devices can also be placed on the existing plug-in system. However, this requires that the planner of the distribution system already envisages as many reserve slots on the plug-in system as possible at the time of initial installation in order to be able to accommodate the additional components and protective devices in future adaptations. However, reality has shown that, in the rarest of cases, this far-sightedness can not be put into practice or implemented at the time of planning. As a result, a user changes his existing plug-in system in a pending expansion only with great reluctance against another plug-in system.

Another problem of the known plug-in systems or plug-in socket systems is that they always have only a certain number of slots for receiving busbars. If, for example, a plug-in system has four receiving stations for receiving three conductors, main busbars and a neutral conductor, then this plug-in system can not be readily supplemented with a protective conductor (PE conductor) or another neutral conductor.

PRESENTATION OF THE INVENTION

Object of the present invention is therefore to show a way in which an existing connector system to new requirements such as the inclusion of at least one additional busbar, additional components and protection devices can be extended.

This object is achieved by an additional base on plug base, with which an existing plug-in system is expandable to a socket assembly. In such a socket assembly, the existing plug-in system forms a so-called main socket. Due to the arrangement of the additional components and possibly arranged so far on the main base terminals on the additional base sufficient space for the additional protection devices on the main base are created. The term "additional components" below accessories such as terminals, also called terminals, understood.

Since the additional socket is to be safe from contact with IP XXB, the plug-in system forming the main socket will first be described below, before the additional socket and the plug-in socket assembly are described.

The aforementioned plug-in system, also referred to below as the main socket, has on a lower side a lower part on which busbars can be arranged, and on a lower side of the underside a non-destructively detachable upper part of electrically insulating material. The upper part, on which protective devices with electrical contacts can be arranged, has openings through which the busbars of the plug-in system can be contacted directly by the electrical contacts of the protective devices. The openings are designed in such a way that the plug-in system is touch-proof according to IP XXB ( EN 60529 ). The upper part ensures contact protection on the upper side.

The upper part is therefore designed with regard to contact protection, clearances and creepage distances as well as switching and arc fault safety so that both finger safety according to IPxxB ( EN 60529 ) as well as the arc fault safety are given. The latter is due to the fact that in the intended use as well as in the case of a foreseeable misuse no short circuit can occur. This includes the arc resistance against falling down of tools or other metal parts as well as cut wires.

The inventive upper part of the plug-in system is covered so that a technician can not accidentally come into contact with the busbars. Since the protective devices in the inventive plug-in system are plugged through the upper part for contacting the electrical contacts with the busbars, is also prevented by the Aufsteckender the protective devices that arranged between the lower part and protective devices upper part can be removed.

Furthermore, there is a contact protection on the entire plug-in system with mounted upper part, d. H. not only are free slots covered, but the protection is also provided when a protective device is temporarily removed for maintenance or assembly.

The system is also easy to implement, because no additional adapter for the electrical contacting of the protective devices are necessary, but the protective devices are directly contactable through the upper part with the arranged on the lower part busbars.

The top offers secure protection because it is different than in EP 0 735 916 A2 itself contains no electrical elements, but is a purely mechanical part, so without electrically conductive parts and thus has a low susceptibility to errors.

According to one embodiment, the upper part can be detached from the lower part exclusively from the lower side of the plug-in system. This further increases the safety of the system, because it ensures that the installer, if he wants to remove the upper part, the plug-in system must first remove and thus the power rails are de-energized in maintenance or installation.

According to a further embodiment, the upper part has additional means by which the protective devices can be plugged onto the plug-in system only when the upper part is mounted and thus only when the busbars are covered. It is not possible in this embodiment, aufzustecken the protective devices without top. The advantage of such an embodiment is that the security of the system is further increased, because it is not possible to set up the protection without the protection provided by the upper part protection.

In the following, the additional socket according to the invention for accommodating additional components based on plug-in bases, with which the above-described plug-in system with protective devices that can be arranged thereon or already arranged, can be expanded to form a plug-in socket assembly, will be discussed. These additional components have further electrical contacts, which automatically forms an electrical connection to one or more further busbars of the additional socket when plugged into the additional socket. The additional base is in several parts, preferably in two parts, and has a further lower part and a further upper part. like the plug-in system, the further lower part also has another lower side and a further upper side. The upper part is non-destructive and repeatedly detachable from the other lower part. The further upper part and the further lower part can be snapped or screwed together so that the further upper part is detachable from the further lower side of the additional base from the further lower part - ie from the rear side of the additional base remote from the further openings.

In further lower part further busbars can be arranged in trained receiving spaces. Depending on requirements, such additional busbars may be, for example, protective conductors, neutral conductors or additional neutral conductors to the neutral conductor of the plug-in system serving as main socket. Depending on the embodiment of the receiving locations they can be formed by ribs, receiving slots or cams of the other lower part, if necessary, also from a combination of several of these elements. A comfortable yet secure opening and closing of the other upper part is achievable when the other upper part is connected via a hinge to the other lower part. This allows optimum accessibility to the receiving spaces after folding the other upper part in the manner of a hinged lid.

A further increase in safety for a user of the additional base can be achieved if the hinge is arranged locally on the additional base, that the additional components in mounted State of the hinge at least partially cover, so that the other upper part is not removable without removal of the plugged additional components from the other lower part, for example, can be folded up.

The further upper part, on which the additional components can be arranged with the further electrical contacts, has further openings. As a result of these further openings, the further busbars of the additional base can be contacted directly by the further electrical contacts of the additional components during insertion. The other openings are designed in such a way that the additional socket is touch-proof according to IP XXB ( EN 60529 ). This allows the operation of the additional base load-free plugging and unplugging the additional components under tension. The other upper part ensures contact protection on the other upper side. For details of the other shell reference is made to the description of the upper part of the plug-in system.

If a distance of the other busbars in the receiving locations is so low that a minimum of a direct air or creepage distance would fall below, these distances can be provided by a corresponding design of the other lower part with recesses and the other upper part with webs analogous to the description of the connector system ,

The advantages of the socket-forming plug-in system and the auxiliary socket give the plug-in socket assembly the same advantages, so that, for example, a plug-in socket assembly composed of a plurality of socket-header strips that is touch-proof according to IP XXB can be realized.

A particularly compact plug-in socket assembly can be achieved if the additional socket is mechanically connected via a coupling to the socket system forming the main socket. In a basic embodiment of the coupling, the additional socket has a first coupling half, which is designed such that it can be detachably coupled into a second coupling half of the plug-in system.

Another advantage of such a header assembly is that it forms a self-contained, self-contained preassembled assembly which, for example, allows convenient preliminary testing and control of the electrical connections between the switchgear of the main header and / or its bus bars during initial installations before the header assembly in a distribution system is installed. This considerably reduces the assembly work of the distribution system on site.

Another advantage is that a mounted in a distribution system, the main socket forming plug-in system can be retrofitted on site even later to a compact socket assembly by the auxiliary socket is mechanically coupled to the main socket.

If it is desired that the plug-in system forming the main socket does not need to be removed from its mounting during retrofitting, then a simple, yet advantageous coupling is required. achievable if the additional base or at least its further lower part can be coupled from the further upper side in the direction of the further lower side into the second coupling half of the plug-in system. This can be achieved, for example, by virtue of the fact that the first coupling half is open towards the further underside of the additional base, while the second coupling half is open toward the top of the main base.

If the plug-in system forming the main socket and the additional socket made of injection-molded parts are made of sprayable, electrically insulating material, the coupling halves can be integrated with the plug-in system and the additional socket during injection molding. This is advantageous because a manual loading of the plug-in system and the additional socket with the respective coupling elements can be avoided before the coupling together.

To ensure that the auxiliary socket is not inadvertently removable from the main socket of the socket assembly, a latch in the form of a snap lock may be provided. If the plug-in system forming the main socket, as well as the additional socket made of injection-molded parts made of sprayable, electrically insulating material, a lock, for example by a latch and a hold-down is integrated with the plug-in system or the additional base.

Depending on the requirements for the connection method to a distribution station, the plug-in system can have a receiving geometry for locking onto a DIN rail. As a result, the additional base is finally secured sufficiently stable over the locking serving as a main socket plug-in system.

If the additional base exceptionally should be attachable to the distribution station as a separate socket skirt, he may have in one embodiment, a further receiving geometry for engaging the additional socket on a DIN rail.

Since there are first types of plug-in systems on the market which are finger-safe according to IP XXB, but also second types of plug-in systems which are not finger-safe according to IP XXB, a coding can be produced in a simple manner by a corresponding design and arrangement of the first coupling half which prevents the inventive additional base can be coupled together with a main socket, which is not safe to touch according to IP XXB. Further embodiments of the invention will become apparent from the further dependent claims and the detailed description.

WAY FOR CARRYING OUT THE INVENTION

1 shows an inventive upper part 2 for a plug-in system 1 in oblique view, on the protective devices 4 with electrical contacts 42 (shown in the 7 and 8th ) can be arranged. The 2 and 3 show the inventive upper part of obliquely below, or from the side. The 4 to 6 show the entire plug-in system 1 in different stages of construction with a lower part 3 on a bottom 12 , on the power rails 5 are arranged, and with one on the bottom 12 opposite arranged upper side 11 a non-destructive from the lower part 3 detachable top 2 made of electrically insulating material. The plug-in system 1 has, for example, as busbars main busbars 52 . 52 ' . 52 '' and depending on the application of the system also neutral 56 or auxiliary busbars 54 . 54 ' on. The top 2 has openings 27 on, through which the busbars 5 directly from the electrical contacts 42 the protective devices are contactable. The openings 27 are designed so that the plug-in system 1 on the top 11 safe to touch according to IP XXB. Touch-proof to IP XXB ( EN 60529 ) means that a standardized test finger may penetrate up to 80 mm into the object to be tested without touching any dangerous parts.

For this purpose, the upper part 2 in the plane of the top 11 first bridges 26 on, leaving at least one of the busbars 5 (as in 4 represented) at least partially coverable. The protective devices 4 can contact the busbars either from above or from the side. With covered busbars, the busbars can only be contacted from the side. A suitable electrical contact is made for this EP 0229590 known. The protection device 4 here has electrical contacts 42 on, which are bent so convex that they in the attached state of the protective device 4 the busbars 5 from the side. Often, the protection device 4 Also contacts on which U-shaped with the opening to the busbar and in the region of the two lateral, mutually parallel parts of the "U's" are slightly bent inwards (tulip or lyre), so that the busbar is contacted from both sides.

It is also possible that the busbars 5 are not covered, but the first bars 26 are arranged between the busbars, so that the contact security is ensured. The electrical contacts 42 the protection devices 4 In this case, you can contact the busbars from the top.

The top 2 can continue to use second bars 28 which are in one plane. perpendicular to the plane of the first webs 26 are arranged. These bridges 28 are as plates between each two adjacent busbars 5 arranged, thus through the second webs 28 be separated. As a result, the stiffness of the upper part as well as creepage distances and creepage distances between the busbars 5 improved.

The top 2 and the lower part 3 a plug-in system 1 are connected with each other in such a way that they can be detached from each other without destroying them. This is important for installation, maintenance or repair work.

In the following examples are shown, as the upper part and lower part 2 . 3 can be connected to each other detachably. Typically, there are at least two connections on opposite lateral side which are perpendicular to the top 11 lie. At least one of the connections is typically a detent connection, while the other connection may also be a detent connection or a tilt connection. In the latching connection, a latching element engages in a latching surface. To release a mechanical force is used to solve the two interlocked parts of each other. In the tilt connection, a rotation of the parts against each other is sufficient to release.

In the 4 to 6 It is shown another exemplary embodiment in which the upper part 2 and the lower part 3 lock into each other. For this, the upper part 2 a first latching element 22 having, which with a second latching element 32 of the lower part is latched into each other. For example, the first latching element 22 be formed as a tab, which in a latching lug formed as second latching element 32 of the lower part snaps. The latching elements overlap in the locked state and must be pushed past each other to solve the connection. Likewise, however, both latching elements can also be used 22 . 32 be designed as latching noses.

Furthermore, the latching can also take place via a further element, for example in the form of a tab, in which latching elements designed as latching lugs on the upper and lower part 2 . 3 be hung. One latching nose is hooked into the tab connected to the other latching nose and thus engaged. Likewise, another latching element could be equipped with two snap-in lugs, wherein in each case a latching nose of this further element engages with the latching noses of the upper and lower part.

Alternatively, the upper and lower parts can also be screwed together. Other alternative releasable compounds or combinations of different releasable compounds are well known to those skilled in the art and are intended to be encompassed by this invention.

The top 2 In a further embodiment, a first tilting element 24 have, for example in the form of a rounded thickening (cylinder segment), which at one to the top 11 of shell 2 located lateral side is located. In the lower part 3 is also a second tilting element 34 (For example, as well as a thickening or a taper, in or on the first tilting element 24 can be placed) on the same lateral side. As in the side view in 6 both tilting elements are shown 24 . 34 merged and the top 2 can now be at a pivot point opposite the lower part 3 be tipped so that the parts 2 . 3 can be folded. 5 shows the plug-in system in an oblique view in the open state, with the upper and lower part 2 . 3 already on their tilting elements 24 . 34 are merged.

Preferably, the first and second latching elements 22 . 32 on one of the lateral side, on which the tipping elements 24 . 34 are arranged opposite side, so that the upper part 2 first with the lower part 3 collapsed and then locked into each other ( 6 ).

The first tilting element 24 of the top 2 may even be designed so that it is so far in the second tilting element 34 protrudes, that for the installation first necessarily the upper part 2 at its first tilting element 24 in the lower part 3 on its second tilting element 34 hooked and then folded, before then with the lower part 3 can be locked in place ( 9 ). For this purpose, the first tilting element 24 with the second tilting element 34 in the assembled state in a lateral plane which is parallel to the top 11 is, for example, an overlap area 243 of 3 mm or even more than 5 mm overlap each other. Due to such a large overlap, the tilting must be done before snapping.

In a further embodiment, the latching elements 22 . 32 designed such that the upper part 2 exclusively from the bottom 12 of the plug-in system 1 from the lower part 3 is solvable. For example, the in 6 shown latching nose 32 of the lower part at the bottom of the lower part 3 appropriate. To release the connection must be the tab 22 from the bottom 12 at least by the distance that the latching nose 32 projecting from the lower part, be removed from the lower part and then from the latching nose 32 be pushed away.

On the plug-in system 1 are protective devices 4 attachable. It is both possible that the top part 2 and lower part 3 assembled and only then the protective devices 4 be attached ( 7 ). Alternatively, the protective devices 4 first on the shell 2 attached and this then on the lower part 3 hooked, or folded and then locked.

For detachable connection of a protective device 4 with the shell 2 can the shell 2 a third tilting element 25 and the protection device 4 a fourth tilting element 45 exhibit. These tilting elements 25 . 45 act similar to the tilt connection between the upper and lower part 2 . 3 so together, that the protection device 4 against the top 2 is tiltable. The lower part 3 can be a third latch 33 and the protection device 4 a fourth latch 43 have, wherein the third and fourth latching element 33 . 43 latched together. Thus, in this embodiment, the protection device 4 on one side with the top 2 collapsed and on the other side with the lower part 3 engaged.

However, the protection device could also be the same 4 instead of a catch with the lower part and only with the upper part 2 be connected and have no direct connection to the lower part. For this example, the protection device 4 having a sixth latching element and the upper part 2 a fifth latching element, which engage with each other. As already described above, the protection device can also be used here 4 collapsed with the top and / or locked.

At the bottom 3 is laterally below the tipping connection between the upper part 2 and lower part 3 a locally distributed second coupling half 35 arranged. The second coupling half 35 is to the top 11 of the plug-in system which can be used as the main socket 1 open and directly to the lower part 3 a glove.

8th shows the inventive plug-in system with attached protective device 4 which with the upper part 2 folded up (tilting elements 25 . 45 ) and with the lower part 3 is engaged (latching elements 33 . 43 ).

Alternatively, the protection device can 4 and the lower part 3 Tipping and latching or even snap-in elements have for mutual latching and folding, so that the protection device 4 only with the lower part 3 non-destructively releasably connected. Again, it is possible that the protection device 4 also with the lower part 3 Have tilting elements and a snap over latching elements on the upper part 2 and protection device 4 is made.

In another alternative, the protection devices 4 on the upper and / or lower part 2 . 3 screwed.

Typically, all are for one protection device 4 for latching or tilting necessary tilting or latching element in a plane perpendicular to the longitudinal direction of the busbars 5 and to the top 11 arranged.

The top 2 and the second latch 32 can preferably be a distance 320 which is at most 5 mm, preferably 3 mm or even smaller than 2 mm ( 6 ). Distance is the minimum distance of the upper part 2 to the lower part 3 in a direction perpendicular to the top 11 and to the power rails 5 level, in which plane the second latching element 32 is arranged to understand. The distance is in the area between the top 11 and the second latching element 32 to determine, ie in the area, through which a tool would have to be passed, if the latching from the top 11 wanted to solve. This distance thus represents the smallest opening that would be overcome by a tool when attempting to use the tool the connection from the top 11 to solve.

At such a small distance 320 It is additionally difficult, if not impossible, the catch between lower and upper part 2 . 3 even with tools from the top 11 to solve.

This can be achieved, for example, by the lower part 3 a lateral edge 36 has (ie perpendicular to the bottom 12 ), which is spaced from the second latching element 32 so that the first latching element 22 in the space between the edge 36 and the second latching element 32 is passed through to the second latching element ( 32 ) to latch ( 6 ). The minimum distance of the upper part 2 to the lower part 3 in a region between the second latching element 32 and the edge 36 , So the area in which a tool would have to be introduced to solve the snap connection is a maximum of 8 mm, preferably 6 or even only 5 mm.

Also the third latching element 33 or possibly a tilting element of the lower part for connection to the protective device 4 can be arranged on the edge. This also creates in gap, in which the first latching element 22 until the second latching element 32 is to introduce. Also this gap can be used as a distance 320 be made small according to the invention.

From the spatial view of an inventive additional socket 10 with another lower part 30 and another top 20 in disassembled state in 10 it turns out that the other top part 20 completely from the other lower part 30 is separable. The additional base is defined by its strip-like shape 10 a longitudinal axis 60 , According to the lower part 3 of the plug-in system 1 is also the other part 30 manufactured in injection-molded construction and has a plurality of transverse ribs 61 on. These transverse ribs 61 extend in the width of the additional base transverse to the longitudinal axis 60 ,

The further lower part 30 has two recording slots 62 for holding two additional busbars 50 on. The recording places 62 are through recesses in the transverse ribs 61 and by grooved depressions in the bottom region of the other lower part 30 educated.

Laterally on the upper part 20 are several first hinge parts 63 and second hinge parts 64 arranged. To accommodate these first hinge parts 63 and second hinge parts 64 are laterally on the other lower part 30 third hinge parts 65 and fourth hinge parts 66 arranged. The first hinge parts 63 can in the third hinge parts 65 intervene, but do not fit in the fourth hinge parts 66 , Accordingly, the second hinge parts 64 in the fourth hinge parts 66 intervene, but not in the third hinge parts 65 , By such a configuration of the hinge 67 is ensured that the upper part 20 not in the longitudinal direction 60 offset on the other lower part 30 improperly mountable, thus allowing an operator the further busbars 50 at least from the other top 110 could touch her.

The other top part 20 has further openings 270 on. Through these other openings 270 are the other busbars 50 of the additional socket 10 directly from the other electrical contacts 420 the additional components 40 automatically plugged in when plugged in. For further details of the other openings 270 is on the description of the openings 27 from the top 27 of the plug-in system 1 directed.

To the additional socket 10 with the main system plug-in system 1 to a socket assembly 70 To be able to mechanically couple together are at the lower part 30 on one the third hinge parts 65 and fourth hinge parts 66 opposite side first coupling halves 68 a glove. These first coupling halves 68 are open to the other top of the additional base and facilitate by their design as a centering hook engaging in the second coupling halves 35 of the main socket 1 ,

To ensure that the additional socket 10 not inadvertently from the main socket 1 the socket base assembly 70 is removable, is a lock 71 provided in the form of a snap closure. To be in a complementarily shaped locking lug of the plug-in system 1 to engage, has the additional base in the longitudinal direction 60 seen between the different parts of the first coupling half 68 a molded down holder 72 on.

To the additional socket 10 on another DIN rail 73 he can put on his other bottom 120 have a further receiving geometry for engaging the additional socket on the DIN rail.

From the synopsis of 10 With 11 shows off that the other top part at its the first hinge parts 63 and second hinge parts 64 opposite side two more first latching elements 220 having latching hooks. From the synopsis of 11 With 14 it turns out that these other first latching elements 220 in the closed state of the other upper part 20 in complementary shaped further second latching elements 321 intervention. As a result, the further first latching elements 220 towards the further underside 120 are so long that they are in the locked state with a plug-in system 1 only from the other bottom 120 are accessible, it is ensured that the other upper part 20 exclusively from the other bottom 120 of the additional socket 10 from the second lower part 30 is releasable (ie in the voltage-free or de-energized state) by the first latching elements 220 be released from the catch. This unlatching from the other top 20 from the other lower part 30 can be done manually or with the help of a tool.

To difference to 11 where the other top part 20 only in the with more power rails 50 equipped further lower part 30 is used, there is the other shell 20 in the presentation of 12 now in a closed state, in which the other first latching elements are engaged in the other second latching elements.

Out 13 shows that the additional socket 10 over the lock 71 mechanically fixed to the main socket forming plug-in system 1 is joined together.

From the 14 shows that also the main socket forming plug system 1 on its underside 12 a mounting geometry for locking the additional socket on a DIN rail 74 can have. In such an embodiment, the entire header assembly is 70 mechanically exclusively via the DIN rail 74 fixable.
