Description

The invention relates to a set of connection adapter and terminal, wherein the connection adapter has electrical contacts for connection with corresponding mating contacts of the terminal, the mating contacts are each received in a terminal formed of insulating material Anschlußklemmendom so that the mating contacts through a respective contact opening in the associated terminal terminal dome for a contact the terminal adapter are accessible, and wherein the terminal terminal dome have plug guides which are adapted to be mated with corresponding bushing guides on the connection adapter for guiding the connection adapter from a Aufsteckposition in which the connection adapter fitting on the terminal and connecting adapter and terminal can be plugged from there, in a locking position in which the connection adapter is seated and held on the terminal so that the electrical contacts of the connection adapter and the corresponding mating contacts of the terminal for electrical contacting are movable relative to each other.

The invention further relates to a terminal and a connection adapter for such a set. The generic connection adapter has an upper housing part which is mounted relative to a lower housing part movable on the lower housing part and accommodates displaceable adapter contacts together with the upper housing part, and a relative to the adapter contacts displaceably mounted protection plate with openings for the adapter contacts that the adapter contacts in a rest position, in which the connection adapter is clamped by a corresponding device connection terminal, concealed by the protective plate in the upper housing part, and in a clamping position, wherein the connection adapter at least partially to a corresponding Device terminal is attached, protrude through the openings of the protective plate in terminal points of the device terminal.

Such sets of connection adapter and terminal are used for example for connecting power supply lines to lights. It may happen that the power supply cable is under voltage. This is dangerous for the fitter and especially problematic when the luminaire connection is performed by a non-specialist.

DE 10 2004 030 440 B4 discloses a lamp terminal adapter with protruding plugs which are inserted into a lamp terminal built into a lamp housing. If the supply lines of the luminaire connection adapter are under voltage, there is a risk of injury due to the lack of contact protection.

EP 0 889 550 B1 describes a two-part electrical connection with a sliding protective cover, which provides protection against contact of the connected conductors for one of the two connectors. The protective cover is designed as a flap attached to the outer housing, which is pivoted by engagement in an inclined guide track of the mating connector.

A similar flap mechanism for contact protection of a plug is in the DE 103 36 082 A1 described. Again, the other part of the connector pair is not protected.

Connection systems without a contact protection are in a variety of configurations, for example from the DE 102 36 398 B3 , of the DE 100 11 613 A1 , of the US 3,860,739 A1 , of the US 2002/0064039 A1 and the US 5,015,203 known.

EP 1 150 399 B1 discloses a multipolar electrical terminal connector with a touch guard to prevent access to at least a portion of the lead terminals of one of the terminal units when the lead terminals of the other terminal unit corresponding to these lead terminals are occupied. The flap is located on the outer housing in front of the connector access and is over a Lifting mechanism connected to another flap of the associated conductor terminal of the other terminal unit.

US 5,885,109 A1 describes an electrical adapter with a spring-loaded protection plate in front of the protected by the protective plates sockets. To connect a plug to the socket formed from the sockets, the protective plate is gripped by the unprotected plugs and displaced against the spring force until the openings in the protective plate, in which the plugs engage, release the jacks behind them.

Such, also known as child safety electrical protection device is also off DE 27 28 429 A1 or in a rotatable embodiment of the movable, spring-loaded protective plate of the DE 87 15 967 U1 known. Such child safety devices for sockets can also be provided as a separate plug-in part, which are plugged into the sockets. This is in the DE 87 15 967 U1 and DE 85 19 135 U1 described.

With this type of contact protection, however, it must be ensured that the cable connections protruding from the connector are not live. This can not necessarily be guaranteed, for example, in the case of a luminaire connection, since the connection socket is installed in the luminaire there for reasons of space to prevent protruding parts during installation, and the connection plug is connected to the supply line carrying the voltage potential.

EP 1 681 747 A2 discloses an electrical device connector for a luminaire having a terminal clipped into the luminaire housing and a connectable connector having a plurality of male or female contacts for external connection to a power cord. The engaging in the lamp terminal connecting contacts of the connector are installed in a longitudinally displaceable on the connector housing mounted contact carrier slide. Only after the contact carrier carriage has been moved into a final assembly position in the direction of the terminal adjacent to the connector terminal and the connection contacts of the connector have intervened in the connection sockets of the terminal, via connecting bracket contacts in the contact carrier is an electrically conductive connection of the connection contacts with the plug or socket contacts and if necessary connected power cords. This way will prevents the protruding from the connector terminals outside the final assembly position can be potential. By a locking stop on the contact carrier carriage, which engages in a counter-stop of the terminal is released in a final assembly of the fixed by the catch stop contact carrier slide and can be further moved in the direction of terminal to connect the terminal contacts of the connector with the connection sockets of the terminal.

Connection adapters and terminals are provided in different versions with different terminal assignment. There is a need to prevent mismatching of non-related connection adapters and terminals of different terminal assignment. At the same time, however, it must be ensured by suitable design that potential-leading terminal contacts are guided safe to touch while the connection adapter and terminal are firmly locked together in the latching position, this construction should be similar for all poles.

Object of the present invention is therefore to provide an improved set of connection adapter and terminal.

The object is achieved with the set of the type mentioned in that the Anschlussadapter- and terminal clamp guides are further coordinated so that a coding depending on the intended pin assignment of existing in the terminal adapter and the terminal for the mutual contacting contacts is provided the one guide of a connection adapter to a terminal or vice versa allowed only with matching terminal assignment.

A pin assignment is defined for an n-pole adapter or terminal (where n = 2, 3, 4, 5 or more) by the line functions associated with the individual terminals, such as ground (E), neutral (N), phase conductors - (L). Then even with the same number of poles a mating of connection adapter and terminal of the same kind, ie within the same plug-in system, but different types due to different terminal assignment can be prevented. However, the pin assignment can also include the number of existing contacts for the mutual contact.

In accordance with the teachings of the present invention, the terminal adapter and terminal clamp guides used to guide the terminal adapter to and from the terminal are also used as coding elements. The connection adapter and connection terminal guides are matched to one another in such a way that it is only possible to place, guide and lock a connection adapter onto a connection terminal if the connection assignment is the same. Depending on the pin assignment thus the Anschlussadapter- and terminal clamps are designed differently, the guiding and locking function is constant. The Aufsetz-, guiding and locking projections and recesses are used according to the invention also for coding, which indeed requires considerable complex considerations in the construction, however, brings significant advantages in the production and application.

The use of the Anschlussadapter- and terminal block guides as coding elements has the advantage that no additional projections and corresponding recesses are required as encodings. For this purpose, the already existing projections and depressions of Anschlußadapter- and terminal guides can be used without affecting the actual purpose of guiding and locking of connection adapter and terminal.

The guides may be formed by protrusions and depressions in the insulating material of the terminal terminal dome and in a corresponding plug-in mounting area of the terminal adapter. In this case, a projection engages, for example, on the insulating housing of the connection adapter in a recess in the insulating material of the terminal terminal of the terminal, so that when appropriate terminal assignment of the connection adapter can be placed on the terminal. Following this, the projection can be guided through the recess into a latching position, in which the connection adapter is latched to the connection terminal, in that the projection on the connection adapter abuts by a further projection on the connection terminal dome and thus a holding function is exerted. The projections and depressions which define the guides are thus initially configured for coding, then for a guide and in the latching position for a holding function.

The coding forming portions of the guides are preferably located at the free end of the terminal dome, i. at the end where the connection adapter first touches the terminal when plugged in. Thus, an insertion of a mismatched connection adapter already prior to the shift operation, i. be prevented at the beginning of attaching the connection adapter to the terminal. This is advantageous in comparison to an embodiment in which the guides initially allow irrespective of the terminal assignment of connection adapter and terminal a first guide of the connection adapter to the terminal and then by a coding during the leadership of terminal adapter and terminal in a locking position latching at unequal Pin assignment is prevented.

The terminal-clamping domes provided for all or some of the electrical contacts are preferably formed integrally with an insulating housing of the terminal. This allows easy manufacture and reliable insulation. In addition, catch spring elements can be integrally formed on the terminal terminal domes in a manner known per se, with which the terminal can be releasably secured to a support plate, for example a lamp panel of a luminaire.

As already described above, the terminal adapter and terminal guide preferably define such a guide track, that in the first step of contacting terminal adapter and terminal are movable towards each other. After reaching a stop position connecting adapter and terminal are movable transversely to each other until a latching position is reached, wherein the electrical contacts in the connection adapter relative to the corresponding mating contacts for mutual contact with each other are movable.

The object is further achieved by the connection terminal for such a set, which has a plurality of respectively received in an associated, formed of insulating material Anschlußklemmendom mating contacts, which are accessible via a contact opening in the terminal terminal dome for a contact of a connection adapter. The terminal domes have terminal adapter guides which are adapted to mate with corresponding terminal lead terminals on a mating terminal adapter for guiding the terminal Connection adapter from a plug-in position, in which the connection adapter fits snugly on the terminal and connector terminal and terminal can be plugged from there, in a locking position in which the connection adapter is seated and held on the terminal so that the electrical contacts of the connection adapter and the corresponding Mating contacts of the terminal for electrical contacting relative to each other are movable. The connection adapter guides are further coordinated so that a coding depending on the pin assignment of existing in the terminal for contacting with contacts of a matching connection adapter mating contacts is provided, which allows a guide of a connection adapter to the terminal or vice versa only with matching terminal assignment.

The problem is further solved by a connection adapter for such a set. Also, the terminal adapter has a plurality of electrical contacts in an insulating material, which are received protected in the unlocked state by a protective plate against contact from the outside, and with unlocking, after reaching a detent position, a movement of the electrical contacts through openings in the protective plate in the direction allow mating contacts of a terminal. Adjacent to the contacts terminal guides are molded in Isolierstoffgehäuse such that the connection adapter from a Aufsteckposition in which the connection adapter fits the terminal and fitting adapter and terminal can be assembled from there, in a detent position in which the connection adapter so mounted on the terminal and it is held that the electrical contacts of the connection adapter and the corresponding mating contacts of the connection terminal for electrical contacting are movable relative to each other. The bushing guides are further coordinated so that a coding depending on the pin assignment of existing in the connection adapter for contacting with mating contacts of a matching terminal contacts is provided, which allows a guide of a connection adapter to a terminal or vice versa only with matching terminal assignment.

For the sake of clarity, it should be noted that in addition to the mating contacts included in terminal terminal domes or via these accessible contacts, further Mating contacts in the terminal or contacts in the connection adapter may be present. For example, a PE contact for secure ground connection may be present on the connection adapter. However, this does not change the basic principle of the present invention.

Object of the present invention is also to provide an improved connection adapter, in particular for a set described above, which is simple and compact.

The object is achieved with the connection adapter of the type mentioned above in that the protective plate is mounted in the lower housing part and in the upper housing part at least one plug contact assembly is installed, each having a group of associated with adapter contacts electrically connected connection contacts.

The integration of the at least one plug contact arrangement together with the projecting downwards in the direction of the lower housing part adapter contacts in the upper housing part has the advantage that the adapter contacts can be rigidly connected to the associated terminal contacts of at least one plug contact arrangement and moved together with the upper housing part. The rigid connection of adapter contacts and associated terminal contacts allows safe electrical contact with high current carrying capacity. On the other hand, the protection plate forming a contact protection for the connection contacts in the resting state is installed in the lower housing part. By installing the plug contact arrangements of the upper housing part is now sufficient space for the leadership of the protective plate available. The height of the connection adapter can be reduced in this way.

It is particularly advantageous if protrude from the lower housing latch hooks. By means of the latching hooks, the alignment and placement of the connection adapter on a device connection terminal can be facilitated by aligning the latching hooks with openings of a mounting plate, wherein the device connection terminal is likewise connected to the mounting plate. The insertion position of the latching hooks in the openings then defines the correct placement position on the device connection terminal.

The upper housing part should then be adapted to the locking hooks locking fingers, wherein the locking hooks and locking fingers are formed so that after locking the lower housing part by engagement of the locking hooks in the opening of a mounting plate, the locking fingers upon displacement of the upper housing part behind the locking hooks in the openings can be positioned and blocked in this way a lead out of the locking hooks from the openings.

This makes use of the fact that, after inserting the latching hooks into the openings and moving the connection adapter into the locking position, part of the openings become free again. These vacant parts of the openings are filled by the locking fingers when the upper housing part is moved downwards in the direction of the mounting plate.

Furthermore, it is advantageous if the underside of the lower housing part provided for abutment with a device connection terminal has guide profiles adapted to outstanding domes of the device connection terminal for sliding on and latching the connection adapter to the device connection terminal. The underside of the lower housing part is thus designed with the aid of the guide profiles so that the placement of the connection adapter on the device connection terminal is possible only in a permissible position, wherein subsequently the displacement of the connection adapter is set in a locking position by the guide profiles.

The integration of the plug contact arrangement in this upper housing part has the advantage that the connection contacts of at least one of the plug contact arrangements can be designed as insulation displacement contacts. In order for a single or multi-wire line can be guided along the top of the upper housing part and connected to the top of the upper housing opposite to the lower housing part outstanding insulation displacement contacts.

The insulation displacement plug contact arrangement is preferably arranged directly above the adapter contacts in the upper housing part. The leadership of the lines on the insulation displacement contacts and the locking thereof is carried out with a guide attachment, the locking elements for locking onto the top of the upper housing part and Wiring guide elements for laying and guiding lines on assigned insulation displacement terminal contacts has. The line guide elements may be formed as a part-circular in cross-section troughs with recesses for the free ends of the insulation displacement contacts. The guide attachment can be connected as a separate part on the upper housing part plugged or pivotally connected to the upper housing part.

However, terminal contacts of at least one of the at least one plug contact arrangement can also be designed as spring terminal connections. As Federkraftklemmanschlüsse are, for example, Käfigzugfederanschlüsse, pressure contact terminals, such as knife-fork contacts or the like.

The two plug contact arrangements can be arranged opposite each other in the upper housing part, so that corresponding connection contacts of the two opposite plug contact arrangements are looped through and with the aid of at least one associated adapter contact a tap on the looped through cable. The adapter contacts are then arranged in the intermediate space between the two mutually opposite plug contact arrangements and protrude transversely to the escape between the two plug contact arrangements downwards in the direction of the lower housing part.

It is also conceivable that at least two plug contact arrangements are arranged vertically one above the other on one side of the upper housing part. In this case, further plug-in contact arrangements can be present opposite to the stacked plug-in contact arrangements, which are in turn arranged one above the other in the direction of displacement of the adapter contacts.

The protective plate may have at least one guide element, such. B. a downwardly projecting downwards in the direction of the terminal surface for a terminal holding fingers, or an opening for receiving a retaining finger of the terminal for holding the protective plate in a fixed position to the terminal in the interaction of the retaining finger with the device terminal, while the lower and upper housing part relative is moved to the protective plate when snapped onto the terminal to align the openings on the adapter contacts.

While the protective plate covers the adapter contacts in the rest position, in which the connection adapter is not clamped to a connection terminal, a displacement of the protection plate relative to the upper and lower housing part and the adapter contacts takes place when the connection adapter is plugged and pushed onto a connection terminal the passage openings are aligned with the adapter contacts and the adapter contacts can be displaced through the passage openings in the direction of corresponding terminals of an adjacent terminal. When placing the connection adapter, the openings of the protective plate are already aligned with leading to contacts in the device terminal insertion openings and the protective plate is in this position relative to terminals using the guide element, such. B. fixed a holding finger. The upper and lower housing part is then moved together with the adapter contacts relative to the protective plate and the terminal until the adapter contacts can be moved through the openings and Einführöffhungen for contacting corresponding contacts in the direction of terminal. The premature depression of the adapter contacts on the protective plate or early removal of the connection adapter from the terminal under overloading of the adapter contacts is prevented by a locking bolt, which then led into the connection position by then aligned locking bolt breaks in the terminal and thus the connection adapter in a position to the terminal sets.

With the help of the lower and upper housing part and the integration of the adapter contacts in the upper housing part and the integration of the protective plate in the lower housing part such a backup of the adapter contacts before touching in a simple and compact way is possible.

The adapter contacts may each be formed integrally with associated connection contacts of the at least one plug contact arrangement. For assembly reasons, it may make sense, however, if the adapter contacts are made separately from the terminal contacts with busbar pieces arranged thereon and an electrically conductive connection of the adapter contacts with associated terminal contacts during assembly of the adapter contacts in the upper housing part.

When integrating the at least one plug contact arrangement into the upper housing part, the problem arises that the upper housing part can be pulled off from the A terminal clamp, possibly by damaging the latching mechanisms, by pulling on lines connected to the plug contact arrangements. Therefore, it is advantageous if the upper housing part is secured to the lower housing part after clamping to a terminal by means of locking brackets, which lock the lower and upper housing part together.

Furthermore, it is advantageous if lower and upper housing part via guide plates are in communication with each other, wherein the guide tabs have stop lugs that prevent removal of the upper housing part of the lower housing part and the sliding of the upper housing part on the lower housing part in the locking position of the upper housing part Prevent clogging.

FIG. 1 is a perspective sectional view of a in the DE 10 2007 044 661.8 from 18 September 2007 described in detail connection adapter 1, which is provided for clamping to a terminal 2 of an electrical device, such as a light. The terminal 2 is here inserted into a device housing plate 3 of the electrical device and fixed there.

The DE 10 2007 044 661 is referred to in terms of the embodiments, which is particularly suitable for coding, guiding and locking used in conjunction with the presently described particular embodiment of the Anschlussadapter- and terminal clamps.

The connection adapter 1 has an insulating 4, in the interior of a protective plate 5 is installed, the z. B. is part of a displaceably mounted in the insulating housing 4 inner housing part. In the protective plate 5 openings 6 are provided to guide through the protective plate 5 protected against contact terminal contacts 7 in the direction of a terminal 2 through and connect the terminal contacts 7 with mating contacts (not shown) of the terminal 2 electrically conductive.

It can also be seen that the connection contacts 7 are guided in the interior of the insulating material 4 by 4 rigidly connected to the insulating housing 4 positioning webs, which are arranged on both sides of the terminal contacts 7. This ensures that the connection terminals 7 are displaced only in the vertical direction and aligned with the openings 6 in a connection position.

The vertical displacement of the connection contacts 7 takes place with the aid of an actuating housing part 9, to which the connection contacts 7 are fixed. The actuating housing part 9 forms, as outlined, a part of the cover closure of the insulating housing 4 and is received and guided by the cover section vertically downward in the direction of the plane of the apertures 6 extending side walls in guide grooves 10 of the insulating housing 4.

The guide grooves 10 are formed by the outer wall of the insulating housing 4 and an outgoing from the outer wall of the insulating housing 4 web 11 in the interior. The terminal contacts 7 are electrically connected to terminal line terminals 12, which are integrated into the insulating housing 4 and provided for connection to a power supply line for the electrical device.

Optionally, however, the connection line connections 12 can protrude from the insulating housing and, for example, cutting contact connections (IDC) for an insulation displacement contact connection to have. However, the connection line terminals 12 may, for example, also have plugs and / or sockets arranged on the outside of the insulating housing 4 or be connected directly to an integrated power cable.

Upon actuation of the actuating housing part 9 by pressing down in the direction of terminal 2, the connection contacts 7 would rest on the protective plate in the protective position and could possibly be deformed thereby. The actuating housing part 9 therefore has a locking bolt 13, which extends from the cover portion of the actuating housing part 9 vertically downwards in the direction of the protective plate 5. In the protective plate 5, as well as the adjoining bottom wall of the insulating housing 4 Sperrriegeldurchbrüche S are provided which are aligned when the Isolierstoffgehäuse 4 is shifted with respect to the protective plate 5 in a connection position, in which the openings 6 for the terminals 9 with not visible breakthroughs in the insulating housing 4 and provided in the terminal 2 mating contacts are aligned.

This ensures that the locking bolt 13 can slide in the connection position through the locking bolt openings S and thus allows depression of the actuating housing part 9 in the direction of terminal 2. The relative movement of Isolierstoffgehäuse 4 and arranged in the interior of the insulating housing 4 protective plate 5 is made possible by the fact that the protective plate 5 has a guide member 14 which comes into operative connection with the terminal 2 to set the protective plate 5 relative to the terminal 2. The guide element 14 may be, for example, a breakthrough in which a guide pin 15 of the terminal 2 engages, which protrudes from the terminal 2 upwards out of the device housing plate 3.

It can be seen that the guide pin 15 is mounted on a terminal dome 16 which protrudes from the terminal 2 through an opening in the device housing plate 3. This connection terminal dome 16 forms a stop for a projecting from the bottom wall of the insulating housing 4 down in the direction of terminal 2, angled stop profile 17. The stop profile 17 is also guided by a locking lug 18 of the terminal 2.

The connection of the connection adapter 1 to the connection terminal 2 takes place in such a way that initially the guide pin 15 is inserted through the guide element 14 designed as a breakthrough. As a result, the position of the protective plate is aligned with the terminal 2 and fixed when the terminal adapter 1 is further shifted. In the following, the insulating material housing is then moved to the right relative to a terminal 2. The alignment and guidance is ensured by the resting on the locking lug 18, angled connection profile 17. The Isolierstoffgehäuse 4 is pushed so far to the right, while the protective plate 5 is fixed until the apertures 6 are aligned for carrying out the connection contacts 7 with corresponding openings in the bottom wall of the insulating 4 and the mating contacts of the terminal 2 and also the locking bar openings S are aligned. This so-called latching position is reached when the connection profile 17 abuts against the terminal terminal dome 16, whereby a further displacement of the insulating housing 4 is prevented. In this locking position, it is now possible to press the operating housing part 9 downwards in the direction of terminal 2, since now the L-shaped paragraph having locking latch 13 is no longer with its narrow end on the top of the terminal 2 and with his paragraph no longer the protective plate 5 rests, but can slide through the aligned locking bolt openings S in the direction of terminal 2 through.

Thus, the operating housing part 9 is no longer blocked, but released. By pressing down the actuating housing part 9, the terminal contacts 7 are guided through the apertures 6 down into the mating contacts of the terminal 2 and thus provide an electrical connection of the terminal adapter 1 to the terminal 2 ago.

Conversely, it is ensured by the L-shaped locking bolt breakthrough S when disconnecting the connection adapter 1 that the terminals 7 can be moved only after reaching a defined by the paragraph of the locking bolt 13 minimum distance from the protective plate 5. The narrow end of the locking bolt 13 also forms a stop for the terminal terminal dome 16 and thus ensures - together with the connection profile 17 - a controlled positioning and guiding.

The electrical connection of the electrical connection contacts 7 with the line terminals 12 can be done either via flexible, hard-wired lines, sliding contacts, insulation displacement contacts or a terminal contact, either in the final position of an electrical contact between the electrical contacts 7 and associated connection line terminals 12 manufactures when the electrical connection contacts 7 are electrically connected to the corresponding mating contacts of the terminal 2.

A disconnection of the connection adapter 4 of the terminal 2 can be done only by the opposite sequence by first the actuator housing part 9 is displaced upwards, the locking bar 13 thereby blocks the blockage of a relative movement between the insulating 4 and protective plate 5 and then the Isolierstoffgehäuse 4 shifted to the left becomes. This is ensured by means of the operative connection of the guide pin 15 and the formed as a breakthrough guide member 14 that the protective plate 5 expires in a protective position in which the electrical connection contacts 7 are protected from contact. Wear-prone aids, such as springs, are not necessary, but may be optional. Rather, the pure motion sequence when connecting and disconnecting the connection adapter 1 is utilized.

According to the teachings of the present invention, the Anschlußademmendom 16 and the stop profile 17 formed Anschlußadapter- and terminal guides are designed not only as described for guiding and locking the connection adapter 1 to the terminal 2, but taking into account the pin assignment of terminal adapter 1 and terminal 2 to each other agreed that the leadership of a connection adapter 1 to a terminal 2 or vice versa only with matching, usually on insulating material pin assignment of the contacts and mating contacts is possible. The pin assignment can be indicated, for example, as a function assignment of the contacts and mating contacts visible on the insulating material.

FIG. 2 shows a perspective view of the connection area of a connection adapter 1. In the insulating housing 4, an electrical contact is received, which after the in the embodiment described above with respect to the FIG. 1 shown type is displaceable. Furthermore, in the connection region of the insulating material housing 4 by depressions 19 and projections 20, a guide channel is formed in which a terminal terminal dome 16 of a corresponding terminal 2 inserted and can be guided into a detent position. In the latching position of the electrical contact 7 can then be connected to a corresponding mating contact of the terminal 2.

It is clear that two opposing wing areas are created by the wells, which are wider compared to an adjacent area. The recesses 19 thus form a T-shape, which is partially bounded by the projections 20. The projections 20 are used to guide the terminal 2 in a locking position in which the projections 20 are above and adjacent to corresponding projections 21 of the terminal 2, as in the FIG. 3 is shown. The in the FIG. 3 sketched terminal 2 is in profile according to T-förtmig, but shorter designed to be first inserted into the recess 19 in the connection terminal 4, moved down below the projections 20 and then moved transversely to the direction of insertion until the locking position is reached in the the terminal 2 are held by the projections 20 and the projections 21 abutting thereto, the projections 21 abutting the boundary walls projecting at right angles from the projection 20 of the connection adapter. In this locking position, the electrical contact 7 can then be moved through a contact opening 22 in the terminal terminal 16 to the mating contacts of the terminal 2.

The movement is from in the FIG. 4 sketched top view better recognizable.

FIG. 4a ) shows a plan view of the connection area of a connection adapter 1, into which the connection terminal dome 16 of a corresponding connection terminal is inserted into a stop position. It can be seen that the projections 21 projecting from the connection terminal dome 16 are inserted into corresponding openings 19 of the connection area in the insulating housing 4 of the connection adapter 1 and the connection terminal dome 16 is displaced downwards until the projections 21 lie below the plane defined by the projections 20.

After reaching the stop position of the Anschlußklemmendom 16 is moved to the right transversely to the direction of insertion until in the FIG. 4b ) shown latching position is achieved. In the latching position, the projections 20 in the insulating housing 4 of the connection adapter 1 abut above the corresponding projections 21 on the connection terminal dome 16 and in this way hold the connection terminal dome 16 on the insulating housing 4 of the connection adapter 1.

While in the in the FIG. 4a shown stop position, the contact bushing opening 22 in the terminal terminal 16 is not aligned with the electrical terminal 7 of the connection adapter 1 is in the in the FIG. 4b ), the contact bushing opening 22 and the contact 7 brought into agreement, so that the contacts designed as a contact pin 7 can dive through the contact bushing opening 22 through to a mating contact of the terminal 2.

The Anschlußadapter- and terminal guides formed by the projections 20, 21 and recesses 19 can be used not only for guiding and holding the connection adapter 1 to the terminal 2. Rather, the Anschlussadapter- and terminal clamps continue to be designed as coding to prevent mismating a connection adapter 1 to a terminal 2, if the pin assignment, such as the assignment of protective conductor, neutral and phase conductors or u. U. also the pole numbers of connection adapter 1 and terminal 2 do not match.

FIG. 5 a) to d) shows by way of example some possible embodiments of the connection adapter and terminal guides for coding.

FIGS. 5a ) and b) show a first coding of the connection adapter ( FIG. 5a ) and the terminal ( FIG. 5b ). In this coding, the projections 21 are located directly opposite the connection terminal dome 16, so that this is in connection with the FIGS. 2 to 4 described T-profile is achieved.

FIGS. 5c ) and d) show a second type of coding in which the projections 21 on the terminal clamping dome 16 are offset and inclined relative to each other as in FIG FIG. 5d ) is sketched. In a corresponding manner, the projections 20 are opposite and obliquely offset from each other in the insulating housing 4 of the connection adapter 1. The depressions 19 are arranged obliquely opposite one another ( FIG. 5c ).

FIGS. 6a ) to d) can be exemplified different designs of the connection adapter guides on the connection dome 16 of a terminal 2 in profile recognize. In addition to the directly opposite projections 21 at the connection terminal dome 16 (FIG. FIG. 6a ) and the obliquely opposite, mutually offset projections 21 according to FIG. 6b ) can also be provided further projections 21 which dip into corresponding recesses 19.

Figures 6c ) and d) show variants in which on one side of the terminal terminal dome 16, two projections 21 are spaced from each other by a recess 23. This depression 23 can in turn dip into a projection 20 on the insulating housing 4 of the connection adapter 1.

Each of these embodiments is provided for a specific, assigned pin assignment of connection adapter 1 and terminal 2, so that connection adapter and terminal with unequal terminal assignment can not be connected to each other.

FIG. 7 shows a perspective view of a connection adapter 1, which is intended for connection to a device connection terminal (not shown). The device connection terminal can be, for example, a luminaire connection terminal built into a mounting plate of a luminaire.

The connection adapter has an upper housing part 24, which is mounted so as to be displaceable downwards on a lower housing part 25 in the Z direction. In the upper housing part 24, a first plug contact arrangement 26a and a second plug contact arrangement 26b is integrated. The plug contact assemblies 26a, 26b are shown in the illustrated Embodiment mounted opposite one another on the side walls of the upper housing part and extending in opposite directions. It is conceivable that, alternatively or additionally, a plug contact arrangement is provided on the upper side of the upper housing part 24, which extends upwardly in the opposite direction to the displacement direction Z. This connector assembly can then be provided with insulation displacement contacts, so that continuous lines can be placed on top of the upper housing part 24 and connected to the insulation displacement contacts.

In the plug contact assemblies 26a, 26b terminal contacts (not visible) are installed to contact corresponding male / female contacts of attachable to the plug contact assemblies conductor connectors or conductor connection sockets.

The attachment of the connection adapter 1 to a device connection terminal is facilitated by latching hooks 27a, 27b which project laterally from the lower housing part 25 and Z in the insertion direction projections and at their ends locking feet 28a, 28b have. After inserting the locking feet 28a, 28b in openings of a mounting plate, in which a device connection terminal is installed, the connection adapter 1 can then be guided through the openings and in the mounting plate and located in the openings latching hooks 27a, 27b in a clamping position.

On the upper housing part 24 protrude to the latching hooks 27a, 27b adapted parallel thereto aligned locking fingers 29a, 29b, which prevent sliding out of the latching hooks 27a, 27b from the openings (not shown) in the mounting plate in the locking position.

Visible is further that at the two, opposite side walls of the upper housing part guide plates 30a, 30b are arranged, which are guided in a closed with a cross member 31 groove 32 and by means of a stop lug 33 complete removal of the upper housing part 24 from the lower housing part 25 to prevent upward by the stop lug 33 abuts against the cross member 31 in a rest position.

Furthermore, for example, on the upper housing part 24 locking tabs 34a, 34b formed, which is locked in the clamping state in which the upper housing part in the Z direction on the lower housing part 25, with the lower housing part 25 and thus the upper housing part 24 in the clamping position on lower housing part 25 secures.

FIG. 8 shows the connection adapter 1 FIG. 1 in the clamping position, which is achieved when the connection adapter 1 is pushed onto a device connection terminal and the upper housing part 24 is displaced in the Z direction downwards. In this state, the locking fingers 29a, 29b secure the directly adjacent latching hooks 27a, 27b from being pushed out of openings in a mounting plate. In addition, the upper housing part 24 is fixed to the lower housing part 25 by means of the locking tabs 34a, 34b, so that even with train connected to the plug contact assemblies 26a, 26b lines the upper housing part 24 can not be removed from the lower housing part 25 with great forces.

FIG. 9 lets the internal structure of the connection adapter 1 in the rest position according to FIG. 7 detect. It is clear that in the upper housing part 24 in the region of the plug contact assemblies 26a, 26b respectively terminal contacts 35a, 35b are added, which are connected by a bus bar piece 36 with each other electrically conductive. The connection contacts 35a, 35b may preferably be integrally formed together with the busbar piece 36 from a sheet material.

From the busbar piece 36 protrudes an adapter contact 37 in the direction of the lower housing part 25. The adapter contact 37 is mechanically electrically connected to the busbar piece 36 and can be manufactured as a separate part, which facilitates the assembly. It is also conceivable that connection contacts 35a, 35b, busbar piece 36 and adapter contact 37 are made in one piece.

The adapter contact 37 is guided at its free end in its guide opening 38 of a guide plate 39. Adjacent to the guide plate 39, a slidably mounted protective plate 40 is provided.

At the lower end of the lower housing part 25 also guide profiles 41 are provided, which are adapted to an adjacent device terminal (not shown) excellent dome 42 of the device terminal to put in the illustrated rest position the connection adapter 1 on the dome 42 and the connection adapter 1 relative to Move the device connection terminal to a clamping position.

The clamping position of the connection adapter 1 is in the FIG. 10 shown.

When placing the connection adapter 1 on the dome 42 of the device terminal clamp engages a downwardly projecting from the protective plate 40 retaining finger 43 in an opening of the adjacent dome 42 to fix the protective plate 40 in a position on the dome 42. Subsequently, the connection adapter 1 can be moved transversely on the dome 42, so that the lower housing part 25 moves with the upper housing part 24 relative to the fixed protective plate 40 and in this way in the clamping position (FIG. FIG. 10 ) Passage openings in the protective plate 40 are brought into alignment with the adapter contacts 37. As a result, the adapter contacts 37, which are protected by the protective plate 40 in the rest position from touching, released so far that they can pass through the openings in the protective plate 40 and insertion openings in the domes 42 of the device terminal through with corresponding contacts in the device terminal to get in touch. In this way, the device connection terminal is electrically contacted with the plug contact terminals of the plug contact arrangement 26a, 26b via the adapter contacts 37.

To disconnect the connection adapter 1 from a device connection terminal, the upper housing part 24 is again pushed upwards away from the lower housing part 25 and then the connection adapter 1 is pulled off transversely from the domes 42. Characterized in that the protective plate 40 is fixed on the retaining fingers 43 to the domes 42, the protective plate 40 is displaced back into the securing position when the adapter contacts 37 are retracted in the upper and lower housing part 24, 25. With the help of the protective plate 40 is an unwanted contact of the adapter contacts 37, which may be excluded by connected to the plug contacts and possibly under voltage potential conductors.

The plug-in contact arrangements 26a, 26b may have additional locking elements 44 in a manner known per se in order to secure attached plug connectors to the plug-in contact arrangements 26a, 26b.

FIG. 11 shows a perspective view of an integrally connected to a busbar piece 36 and opposing terminal contacts 35a, 35b adapter contact 37, which is inserted into an associated guide opening 38 of a guide plate 39 and through a passage opening in the protective plate 40 in an insertion opening of a corresponding dome 42 a Device connection terminal 2 emerges. The connection contacts 35a, 35b may be formed, for example, as connector contacts, as shown. In this case, a fork (left connection contact 35a) contacts a blade contact (compare right connection contact 35b), which is inserted into the fork contact. Equally, however, other types of connection contacts can be used, such as tension spring terminals, insulation displacement contacts, screw contacts or the like.

FIG. 12 allows a perspective view of a section of a connection adapter 1 with adapter contacts 37 detect, in which above the adapter contacts 37 integrally connecting contacts 35c in insulation displacement technology (IDC) are integrally formed. By integrally formed with the adapter contact 37 at the upper end insulation displacement contacts a plug contact arrangement can be provided in a simple and space-saving manner at the top of the upper housing part 24. The conductors to be connected are in this case inserted into the upper housing part 24 formed conductor receptacles and pressed by means of a lid and possibly a clamping pliers in the insulation displacement contacts 35c. The lid is then latched and / or welded to the upper housing part 24.

FIG. 13 shows a perspective view of another embodiment of a connection adapter 1, in which the assignment of connection contacts 35a, 35b with associated adapter contacts 37 by means of jumpers 45 takes place. This bridge 45 can be arranged above the adapter contacts 37 and preferably, for example, integrally formed in the upper free end of the adapter contacts 37 fork contacts 46 are inserted. The bridge plane, on which the fork contacts 46 are arranged, thus lies above the adapter contacts 37, so that the size of the connection adapter 1 is small can be held. The connection contacts 35a and 35b of the plug-in contact arrangements 26a, 26b are connected rigidly to one another via the bridges 45.

The jumpers 45 may be assembled during manufacture and installed in the upper housing part 24. It is also conceivable, however, for the jumpers 45 to be integrated in a separate bridge plug, which is placed on the adapter connection housing which is partially open in the region of the fork contacts 46 for receiving the bridge plug.
