Description

The invention relates to a connection module for attachment to a busbar module.

In order to simplify the wiring effort for distributing a direct current along a mounting rail, the direct current can be passed on from one connection module to an adjacent connection module on the mounting rail. The document EP 2 086 1 0 1 A2 describes connecting slides in order to electrically connect adjacent connection modules on a mounting rail with regard to a potential. However, such connecting slides increase the overall height of the connection modules, can only transfer a single potential and the number of contact points increases with the length of the distribution system, which is why it is unsuitable for high direct currents, for example for distributing a direct current of the order of 40 A.

In order to reduce the wiring effort and to distribute such a direct current, busbars can be used that extend continuously along several connection modules. The corresponding connection modules are then plugged onto this distribution busbar system. Since the mechanical connection of the connection modules on the busbar modules ensures the electrical contact, this must be reliable and detachable.

The invention has the object of specifying a technique for the reliable, detachable fastening of a connection module to a busbar module.

The object is achieved according to the invention with the features of the independent claim. Appropriate configurations and advantageous developments of the invention are specified in the dependent claims.

Further features and advantages of exemplary embodiments of the invention are described below with partial reference to the drawings.

One aspect of the invention relates to a connection module for mounting on a busbar module or a plurality of busbar modules that extend in a longitudinal direction. The connection module comprises a housing, the rear side of which is mounted or can be mounted on the busbar module or modules. The connection module further comprises a bolt that is movable transversely to the longitudinal direction on a first longitudinal side of the rear side for the form-fitting connection of the connection module with the busbar module or the busbar modules in a mounted position of the connection module. The connection module further comprises a latching profile on a second longitudinal side of the rear side opposite the first longitudinal side for the form-fitting connection of the connection module to the busbar module or the busbar modules in the mounted position.

In exemplary embodiments, because of a pluggable contact (i.e. a pluggable contact between the rail contacts of the connection module and the respective busbars of the busbar module or modules), it may be important to ensure sufficient mechanical support, for example against environmental influences, between the connection module and the busbar module (s). This hold can be achieved through the form-fitting connection by means of the bolt and / or the latching profile.

In exemplary embodiments, the connection module (for example an electrical device circuit breaker) can be plugged into the busbar module or modules (for example a distribution rail system) (for example starting from the unlocked position), can be removed (for example by pressing the control surface starting from the mounted position) and / or can have a sufficient hold against environmental influences in the assembled position.

In a distribution rail system (also for short: system) with several connection modules, for example on the busbar module or several interconnected busbar modules, embodiments enable the individual connection modules (for example device circuit breakers) to be changed from the system, for example from a network with several adjacent connection modules.

An operating surface of the pivot lever can be arranged on the front side of the connection module or be accessible from the front side of the connection module. Exemplary embodiments can enable a single connection module (for example a device circuit breaker) to be conveniently removed from the group. Since individual connection modules can be attached and / or removed within a group of adjacent connection modules (preferably also on an extension of the busbar module to form a distribution system), a direct current can be distributed without creating a gap or gap (e.g. due to the expansion of the distribution system).

The back can have a mounting recess for receiving the power rail module the assembled position. The first longitudinal side and the second longitudinal side of the rear side can include mutually facing surfaces, for example mutually facing surfaces of the mounting recess. The surface of the first longitudinal side can have an opening. In the assembled position, the bolt can protrude from the opening. As an alternative or in addition, the surface of the second longitudinal side can have the latching profile.

The connection module can furthermore comprise a pivot lever mounted in the housing such that it can pivot. The pivot lever can pivot between the mounted position and an unlocked position. During the pivoting movement from the unlocked position into the mounted position, the pivot lever can move the bolt out of the housing of the connection module for a positive connection with the busbar module.

The connection module, for example the pivot lever, can also include a stamp. The stamp can be designed to move the pivot lever from the unlocked position into the mounted position when the connection module is being installed.

During the pivoting movement from the mounted position into the unlocked position, the pivot lever can press a stamp of the connection module, preferably the pivot lever, (for example the aforementioned stamp) against a contact surface of the busbar module. For example, the pressure of the stamp can release a contact between the rail contacts of the connection module and the respective busbars of the busbar module or modules.

The pivot lever can be pivotable into the unlocked position by means of an operating surface protruding from the housing on a front side in the mounted position. For example, actuation of the operating surface can pivot the pivot lever into the unlocked position and thus cause the stamp to press on the contact surface of the busbar module to release the contact.

The pivot lever can be pivotable from the unlocked position into the mounted position by means of a resilient element.

The resilient element can be connected to the pivot lever. The resilient element can comprise a portion that is movable relative to the pivot lever. During the pivoting movement between the unlocked position and the mounted position, the movable section can hit an obstacle ( 125 ) issue.

The obstacle can serve as a bearing of the movable section that is fixed relative to the connection module. During the pivoting movement, the fixing of the movable section relative to the connection module can result in a movement of the movable section relative to the pivot lever, which causes the spring force to return the pivot lever to the mounted position.

The pivot lever can be mounted in a monostable manner with respect to the unlocked position and the mounted position, for example with the mounted position as the rest position.

As an alternative or in addition, the pivot lever can be mounted in a bistable manner with respect to the unlocked position and the mounted position. The bistable mounting can comprise a resilient element (for example the aforementioned resilient element) with a sliding section. During the pivoting movement between the unlocked position and the mounted position, the sliding section can slide over an obstacle arranged in the housing (for example the aforementioned obstacle).

The resilient element can for example comprise one, two or more curved spokes. The spokes can be curved in a plane of pivoting movement. The spokes can extend (at least substantially) radially from a pivot bearing of the swivel lever. The spokes can extend (at least substantially) radially with respect to the pivot bearing of the pivot lever. The spokes can be connected to one another at the movable section or at the sliding section.

The pivot lever, the resilient element (for example including the spokes, the movable section and / or the sliding section), the stamp and / or the operating surface can be formed in one piece, for example by means of injection molding.

The connection module can also be designed to branch off a direct current distributed along the busbar module or modules. Optionally, the connection module can comprise at least two connection contacts for connecting a consumer or a source of direct current. The connection contacts can be arranged on a front side of the connection module.

As an alternative or in addition, the connection module can comprise at least two rail contacts protruding from the rear. The For branching off the direct current, rail contacts can be designed to contact (for example, to clamp) a conductor rail of the conductor rail module when the connection module is in the position mounted on the conductor rail module. For example, at least one or each of the rail contacts comprises a double-sided spring contact which is designed to contact the respective busbar in a spring-elastic manner on both sides.

In the housing, the rail contacts on the rear and the connection contacts on the front can be electrically connected to one another in pairs. An overcurrent protection device to protect the consumer or the source of direct current can be connected between the rail contacts on the rear and the connection contacts on the front.

The rear of the connection module can be mounted or mountable on at least one busbar module. In the mounted position, the bolt (for the form-fitting connection of the connection module with the power rail module) can rest against a shoulder of the power rail module. As an alternative or in addition, in the assembled position the latching profile (for the form-fitting connection of the connection module to the busbar module) can be in engagement with a complementary latching profile of the busbar module. The rail contacts of the connection module can contact the busbar module when the connection module is in the mounted position.

Furthermore, the rear side can be mounted or mountable on a first and a second busbar modules adjoining one another in the longitudinal direction on their respective end faces. The bolt for the positive connection of the connection module with the first and the second busbar module in the mounted position can rest both on a shoulder of the first busbar module and on a shoulder of the second busbar module. As an alternative or in addition, the locking profile for the positive connection of the connection module to the first and second busbar modules in the mounted position can be in engagement with both a complementary locking profile of the first busbar module and a complementary locking profile of the second busbar module. At least a first of the rail contacts of the connection module can contact the first busbar module and at least a second one of the rail contacts of the connection module can contact a second busbar module of the adjacent busbar modules when the connection module is in the mounted position. In other words, the connection module can be mounted or mountable over an end connection point (also: extension) of two adjacent busbar modules (preferably without loss of slot space or vacancy at the connection point).

The connection module can include an overcurrent protection device between the rail contacts and the connection contacts to protect the consumer or the source of the direct current. The overcurrent protection device (also: fuse, preferably: device fuse) can be an electronic fuse.

The busbar module can be attached to a mounting rail. The connection module can be connected to a data bus along the mounting rail, preferably via data bus contacts on the housings of the connection modules that touch each other in the mounted position. The connection module can output a status of the electronic fuse via the data bus. Alternatively or in addition, the connection module can receive an instruction to reset (i.e. to reset or close) the electronic fuse via the data bus.

In embodiments of the busbar module, by arranging the busbars between a rear section and a front section, transverse webs on the front section can prevent unintentional contacting or short-circuiting of the busbars. In the same or other exemplary embodiments of the busbar module, since the transverse webs extend transversely to the longitudinal direction, the busbars can each be contacted by a spring-elastic rail contact of the connection module in the transverse direction (i.e., along a gap between the transverse webs). As a result, the connection modules can be narrow in the longitudinal direction or more connection modules can be mounted on a given length of the mounting rail.

Embodiments of the busbar module can enable the distribution (for example the line and / or branch) of the direct current parallel to the mounting rail. The installation space can be used in an optimized way, for example without increasing the installation height of the connection modules, in that the busbars are arranged in a U-shaped recess in the support rail by means of the busbar module.

The busbar modules can reduce the wiring effort for distributing the direct current to the connection modules (for example from the connection modules, for the connection modules or via the connection modules) on the mounting rail. The direct current can be a Operating current for operating the respective connection module or a consumer fed by means of the connection module.

An upper edge of the busbar can be within the housing of the busbar module. The upper edge of the busbar can be arranged lower (i.e. further to the rear section or to the support rail) than the crossbars. In this way, an inadvertent short circuit can be prevented, preferably without isolating the upper edge, as a result of which production can be simplified and / or the rail contacts do not have to overlap an insulation at the upper edge.

A nominal voltage of the direct current can be 12 V to 24 V or 24 V to 48 V.

The housing of the busbar module, preferably the rear section, can have shoulders on a first longitudinal side for mounting the connection module. As an alternative or in addition, the housing of the busbar module, preferably the rear section, can have latching profiles on a second longitudinal side for mounting the connection module.

The bolt can be designed to cooperate in the mounted position of the connection module with a shoulder or several shoulders of the respective busbar module for a form-fitting connection. In an assembled position, the bolt can rest on the respective paragraph and / or release the paragraph in the unlocked position. As an alternative or in addition, each of the latching profiles can be designed to be in positive engagement with a complementary latching profile of the respective busbar module in the mounted position of the connection module.

In the housing of the busbar module, an electrically insulating partition wall can be arranged between two adjacent busbars of the at least two busbars (for example each).

The support rail comprise latching webs that protrude transversely to the longitudinal direction. The mounting rail can be a U-shaped top hat rail, for example according to FIG Standard DIN EN 50 022 be. The top-hat rail can have side legs with latching webs which are bent outwards.

The rear section of the or each busbar module can have at least two opposing, mutually facing latching lugs. The latching lugs can be designed to slide from a loose position of the busbar module over the latching webs of the support rail into a latching position of the busbar module, in which the latching lugs positively connect the rear section of the busbar module to the support rail.

The busbars in the busbar module can comprise a busbar for functional grounding, a busbar to a neutral conductor and a busbar to a positive pole. The busbars can form a power bus (also: "Powerbus").

Furthermore, the busbar module can comprise, on at least one end face of the busbar module, in each case a punched contact which is plugged or can be plugged onto an assigned busbar in the longitudinal direction. The punched contacts can be designed to electrically connect the busbars of the busbar module to corresponding busbars of a busbar module adjoining the respective end face.

The punched contacts can enable modular expandability of the busbar module along the mounting rail. The stamped contacts can be mirror-symmetrical in the longitudinal direction with respect to the end face. At least one or each of the stamped contacts can comprise two, three or more laminated metal sheets of the same shape, stacked one on top of the other.

In exemplary embodiments, the punched contacts can each electrically connect the individual busbars of the directly adjoining busbar modules (for example, butting against one another at the end), preferably without loss of slot. As an alternative or in addition, the punched contacts can enable the construction of a distribution system (also: distribution rail system) with a large number of busbar modules. The distribution system can thus be modularly expandable, for example through the separate electrical connection of the associated busbars. For example, the stamped contacts can comprise a space-optimized busbar connector for a distribution system with 24 V direct current.

At least one or each of the stamped contacts is preferably designed to carry an electrical connection of the associated busbars for 40 A continuous current.

The stamped contact can extend in the longitudinal direction or in alignment (i.e. in a straight line) of the two electrically connected busbars. The stamped contact can be perpendicular to the height of the associated busbar.

To protect against overload and / or short circuit, preferably from electrical 24 V DC consumers, the connection module can comprise an (for example electronic) device circuit breaker. The device circuit breaker can be designed to limit a consumer current (ie the current branched off on the busbars and / or the current output at the connection contacts) to a certain value (for example 40 A).

The connection contacts of a connection module can comprise an output channel (for example with two or three connection contacts) or several output channels. The consumer current can be protected individually for each output channel. For example, a current of up to 40 A can be assigned to a connection module or an output channel.

In the exemplary embodiment, a connection module mounted indirectly (i.e. indirectly) on the mounting rail via the power rail module for tapping the direct current distributed along the mounting rail can be made possible. The busbar module according to the first aspect can be designed for fastening on the mounting rail. The connection module according to the second aspect can be designed for fastening on the rail module.

The connection module can be connected or connectable to the mounting rail indirectly (preferably exclusively indirectly and / or exclusively by means of the busbar module). The connection module can only be connected or connectable to the busbar module, which in turn is connected or connectable to the mounting rail.

Exemplary embodiments can be installed or installable on a universal or existing mounting rail, for example on a mounting rail that is not limited to a direct current system or a system for distributing the direct current. By means of the busbar modules specific for direct current and / or designed for direct current, an existing mounting rail for distributing the direct current can be developed. Alternatively or in addition, the indirect mounting of the connection modules on the mounting rail or the form-fitting connection of the connection modules on the busbar module can ensure that the connection module and the busbar module are designed for the same or a coordinated current (for example the same or coordinated current type, current strength and / or voltage) .

At least one or each of the rail contacts can comprise a double-sided contact, for example a double-sided spring contact (preferably a tulip contact). The spring contact can be designed to make elastic contact with the respective busbar on both sides. At least one or each of the rail contacts can be designed to contact the busbar in a spring-elastic manner from both sides in a gap between the transverse webs. The rail contact can be a double-sided double contact or a double-sided multiple contact with two or more contacts on each side of the busbar.

1 shows a schematic sectional view of a connection module for mounting on a busbar module or on a plurality of busbar modules that extend in a longitudinal direction. The connection module is generally given a reference number here 100 designated. The longitudinal direction, LR , is perpendicular to the image plane 1 .

The connection module 100 includes a case, the back of which 106 is mounted or mountable on the busbar module or modules. The connection module also includes 100 one on a first long side, LS1 , the back 106 transverse to the longitudinal direction LR movable latch 114 to positive connection of the connection module 100 with the busbar module or the busbar modules in a mounted position of the connection module 100 . Alternatively or additionally, the connection module comprises 100 a locking profile 126 on one of the first long sides LS1 opposite second long side, LS2 , the back 106 for the positive connection of the connection module 100 with the busbar module or the busbar modules in the mounted position.

This in 1 Shown embodiment of the connection module 100 points at the back 106 a mounting recess 110 to accommodate the power rail module in the assembled position.

The first long side LS1 and the second long side LS2 the back 106 include mutually facing surfaces, preferably in the mounting recess 110 . The area of the first long side LS1 has an opening from which the bolt 114 protrudes in the assembled position. In the unlocked position, the bolt 114 be completely within the housing. The area of the second long side LS2 shows the locking profile 126 on.

There is a swivel lever in the housing 112 pivotally mounted. 1 shows an example of a pivot bearing 116 for supporting the swivel movement of the swivel lever 112 .

The pivot lever 112 is pivotable between the mounted position and an unlocked position. During the pivoting movement from the unlocked position to the mounted position, the pivoting lever moves 112 the latch 114 from the housing of the connection module 100 out for a form-fitting connection with the power rail module.

The latch 114 can be via a lever arm with the swivel lever 112 be rotatably connected, for example as in the embodiment of 1 shown. Alternatively, the latch 114 be mounted longitudinally movable, the pivoting movement of the pivot lever 112 with the longitudinal movement of the bolt 114 is coupled.

The connection module 100 further comprises a stamp 124 . The Stamp 124 can in the in 1 locked position shown must be completely in the housing. In the unlocked position, the stamp 124 protrude from the housing, preferably within the mounting recess 110 .

The Stamp 124 can be via a lever arm with the swivel lever 112 be rotatably connected, for example as in the embodiment of 1 shown. Alternatively, the stamp 124 be mounted longitudinally movable, the pivoting movement of the pivot lever 112 with the longitudinal movement of the punch 124 is coupled.

When installing the connection module 100 the stamp can be in contact with the busbar module and pressed into the housing by the busbar module. This allows the stamp 124 the pivot lever 112 Move from the unlocked position to the assembled position.

Optional includes the swivel lever 112 a resilient element 122 . By means of the resilient element 122 can latch 114 be pre-tensioned in the assembled position, that is, the bolt does not give way until a minimum force determined by the pre-tensioning 114 from the assembled position.

In each embodiment, a front side 102 of the housing at least two connection contacts 104 for connecting a consumer or a source of direct current. The connection module 100 further includes at least two on the rear 106 , preferably in the mounting recess 110 , protruding rail contacts for branching off the direct current. The rail contacts are designed to each contact a busbar of the busbar module when the connection module 100 is in a position mounted on the busbar module.

In each exemplary embodiment, the connection module 100 include a device circuit breaker, for example an electronic fuse for a DC voltage, preferably 24 V.

As based on the exemplary embodiment of 1 Described by way of example, embodiments of the busbar module 200 Form a distribution system, preferably for distributing a direct current with 24 V. In the distribution system (for example by means of punched contacts) the busbars of adjacent busbar modules can be in electrical connection.

The busbar module or the busbar modules can be releasably attached to a mounting rail, for example a top-hat rail, by means of latching lugs. The locking lugs can be on the first long side LS1 or second long side LS2 be molded.

The power rail module in the longitudinal direction is optional LR (and opposite to it) movable on the mounting rail. The longitudinal movement enables the end faces of busbar modules that are adjacent on the mounting rail 200 be brought into plant. A stamped contact can electrically connect the front ends of corresponding busbars of the adjacent busbar modules to one another.

In order to be able to transmit a current strength of, for example, 40 A continuous current with the smallest installation space, a flat stamped contact can be used multiple times, preferably in triplicate, to one Assembly be manufactured. As a result, the multiple contact points of a stamped contact (for example the three individual contact points of each laminated sheet of the stamped contact) can divide the current among one another, so that overall heating is reduced.

Furthermore, this assembly group of the stamped contact is only slightly built up, so that this electrical connector of the busbars can be placed below a busbar contact (i.e. an electrical tap for contacting the individual busbars) of the mounted connection modules.

2 shows on the left one of the sectional view of the 1 corresponding side view of the pivot lever 112 . Furthermore, the right side shows the 2 and an edge view of the pivot lever perpendicular thereto 112 according to the embodiment of 1 . 3 shows two perspective views of the pivot lever 112 according to the embodiment of 1 and 2 .

That on the swivel lever 112 attached spring-elastic element 122 can one regarding the pivot lever 112 movable section 123 include. The moving section 123 can during the swivel movement of the swivel lever 112 in the housing of the connection module 100 be stationary, for example on an obstacle in the housing of the connection module 100 rest on one side. This allows the resilient element 122 Both in the assembled position and in the unlocked position exert a preload that secures the pivot lever in the assembled position or moves it from the unlocked position into the assembled position. A monostable mounting of the pivot lever can thus be realized.

In one variant, the resilient element comprises 122 a sliding section 123 for bistable mounting of the pivot lever. The sliding section 123 can during the swivel movement of the swivel lever 112 between the mounted position and the unlocked position via an in the housing of the connection module 100 Fixed obstacle slide. For example, the resilient element can thereby 122 both in the assembled position and in the unlocked position, a bias voltage securing the respective position on the pivot lever 112 exercise. Preferably, the preloads of the mounted position and the unlocked position are directed opposite to one another.

The spring-elastic element 122 comprise two curved spokes (e.g. spring legs). The spokes can be on the movable section with respect to the pivot lever 123 (e.g. in the case of monostable storage) or on the sliding section 123 (eg in the case of bistable storage) are connected to one another.

The section 123 can, as in the 2 shown on the left, from a plane of the pivot lever 112 (against the longitudinal direction LR or in the longitudinal direction LR ) protrude. The section 123 can with the outside of the pivot plane of the pivot lever 112 arranged obstacle interact.

4th shows one of the 1 corresponding sectional view of the exemplary embodiment of the connection module 100 on an exemplary power rail module 200 is mounted. That is, the exemplary embodiment of the connection module 100 (especially the swivel lever 112 of the connection module 100 ) is related to the exemplary power rail module 200 in the assembled position.

The connection module is preferably 100 designed to have one in the longitudinal direction LR , for example along a mounting rail, to branch off distributed direct current. The mounting rail can be a conventional top hat rail.

The exemplary busbar module 200 comprises a housing, the electrically insulating rear section of which is connected or can be connected to the support rail in a form-fitting manner.

For example, includes the busbar module 200 facing locking lugs 236 and 238 on an underside of a rear section of the busbar module 200 . When the power rail module 200 (for example, by applying pressure to the contact surface 230 ) is pressed onto the mounting rail, the locking lugs slide 236 and 238 Via locking webs of the support rail that are opposite in the transverse direction and facing away from one another for the form-fitting connection of the rear section with the support rail.

A front portion of the housing has a plurality of transverse to a longitudinal direction LR of the power rail module 200 extending, electrically insulating transverse webs. Furthermore, the busbar module comprises 200 at least two in the housing between the rear section and the front section in the longitudinal direction LR extending busbars 212 , which are designed for this, through a gap between the transverse webs of the connection module 100 to be contacted for branching off the direct current when the connection module 100 in the one on the power rail module 200 mounted position. The alignment of the transverse webs is also referred to as the transverse direction.

The rear section of the housing of the busbar module comprises on the first longitudinal side LS1 a paragraph 216 with a retaining surface which preferably faces away from the front section and / or faces the support rail. The retention surface is parallel to the longitudinal direction LR and the transverse direction.

Each embodiment of the connection module 100 can, as exemplified in the 4th shown in the housing of the connection module 100 pivotable swivel lever 112 include. The pivot lever 112 is between the (for example in the 4th shown) mounted position and the unlocked position pivotable. The pivot lever 112 includes a latch 114 , which in the assembled position with the heel 216 cooperates, preferably on the retaining surface of the paragraph 216 for the positive connection of the connection module 100 on the busbar module 200 . In the (for example in the 5 shown) unlocked position gives the bolt 114 the paragraph 216 free.

The pivot lever 112 can on a plain bearing 116 in the housing of the connection module 100 be pivotally mounted. Alternatively or in addition, the pivot lever 112 with a sliding surface 118 of the pivot lever 112 on a stationary sliding surface 120 in the housing of the connection module 100 be pivotally mounted.

The pivot lever preferably comprises 112 a resilient element 122 that puts a bias on the pivot lever 112 exercises. In a first variant, the pretensioning of the resilient element can be used 122 the pivot lever 112 to pivot from its unlocked position to the mounted position. For this purpose, the resilient element 122 one with respect to the pivot lever 112 section movable within a plane of pivoting movement 123 include. The one regarding the pivot lever 112 movable section 123 rests on one in the connection module during the swivel movement 100 stationary arranged obstacle 125 on. The resulting deformation (preferably change in curvature) of the spokes of the resilient element 122 results in a spring force that acts on the pivot lever 112 able to move from the unlocked position to the mounted position.

In a second variant, which is in the 4th and 5 is shown schematically, comprises the resilient element 122 a bistable sliding section 123 . The bistable sliding section 123 lies in the (for example in 4th shown) mounted position on a first side of an obstacle 125 (for example, to the left of the obstacle 125 in 4th ). In the (for example in 5 shown) unlocked position is the bistable sliding section 123 on a second side of the obstacle opposite the first side 125 (for example, to the right of the obstacle 125 in 5 ). By means of the between the first page and the second page over the obstacle 125 sliding bistable sliding section 123 can the swivel lever 112 be bistable with respect to the unlocked position and the mounted position.

Optionally (for example in the first and / or the second variant) by the bias in the mounted position of the pivot lever 112 when installing the connection module 100 a bevel of the bolt 114 over the bevel of the paragraph 216 slide the latch 114 at the heel 116 come into engagement and be secured in the assembled position.

The pivot lever preferably comprises 112 a stamp 114 which is arranged for this purpose during the pivoting movement of the pivot lever 112 from the mounted position to the unlocked position on the contact surface 230 of the power rail module 200 exert a pressure on the power rail module 200 from the mounting recess 110 of the connection module 100 pushes out.

Alternatively or additionally (for example if the swivel lever 112 is not yet in the assembled position) when assembling the stamp 124 from the contact surface 230 into the housing of the connection module 100 are pressed, causing the pivot lever 112 , and thus the one with the swivel lever 112 connected latch 114 , is moved into the assembled position.

On the latch 114 in the transverse direction opposite second longitudinal side LS2 is a to the locking profile 126 of the connection module 100 complementary locking profile 220 of the power rail module 200 arranged. For example, the locking profile includes 126 of the connection module 100 a recess and the complementary locking profile 220 of the power rail module 200 a projection that is complementary in shape to the recess, or vice versa.

Optional includes the back 106 , preferably the recess 110 , a spring-elastic bearing 128 of the locking profile 126 . The spring-elastic storage 128 can be implemented by a weakening (for example a local reduction of a wall thickness) of a wall on which the locking profile 126 is arranged. The locking profile is an alternative or a supplement 126 via a resilient element 130 at the back 106 supported.

In the in 4th The locking profiles are shown in the mounted position 126 and 220 on the second long side LS2 as well as the latch 114 and the paragraph 216 on the first long side LS1 each engaged.

In the in 5 The unlocked position shown is the connection module 100 in the mounting recess 110 from the busbar module 100 moved away compared to in the 4th shown mounted position. The locking profiles 126 and 220 on the second long side LS2 as well as the latch 114 and the paragraph 216 on the first long side LS1 are each disengaged.

The rear section of the housing optionally comprises on the second longitudinal side LS2 a stop 222 , the deeper (ie from the connection module 100 further away) than the locking profile 220 .

For mounting a connection module 100 , for example when transitioning from the in 5 unlocked position shown in 4th shown mounted position, the connection module 100 initially only at the stop 222 be brought into contact and then in a tilting movement with the longitudinal direction LR as the axis of rotation on the first long side LS1 about the paragraph 216 be pushed. In this case, the bolt 214 on the connection module can over the outwardly inclined bevel of the shoulder 216 slide and / or behind the heel 216 rest in a form-fitting manner on the retaining surface, the latching profile 126 on the opposite second long side LS2 is positively engaged with a complementary locking profile 220 of the power rail module 200 .

For example, when unlocking the connection module 100 First of all, the form fit between the bolt is achieved by a rotational movement 114 and paragraph 216 (for example an undercut of the latching) released and then the pivot lever 112 against the second long side LS2 (For example, an upper edge of the power rail module 200 ) must be pressed to release the contacts and the connection module 100 to be highlighted from a network of connection modules so that it can be easily pulled out.

While in the 4th and 5 the busbars 212 of the exemplary power rail module 200 with one flat side of the connection module 100 are facing, in a variant of each exemplary embodiment, the busbar with an edge to the connection module 100 be aligned. In such a variant of the connection module 100 the rail contact of the connection module 100 include a double-sided tulip contact. In order to achieve a sufficiently large contact area for the current intensity to be tapped, each rail contact preferably comprises a double-sided double contact, ie the conductor rail is contacted twice on each side.

The connection module 200 can between adjacent busbars 212 of the connection module 200 each comprise a partition that extends in the longitudinal direction LR extends. Preferably each bus bar is 212 in a longitudinal direction LR extending groove 234 edged.

Each embodiment of the connection module 100 can include a device circuit breaker, preferably for 24 V DC and / or a current limit value of 20 A to 40 A. In a distribution system with one or more busbar modules 200 can direct current to several connection modules 100 can be distributed, for example, without the need for wiring when branching off the direct current from the busbars 212 . The power rail module 200 or the busbar modules that are electrically connected to one another 200 can also be referred to as "Powerbus".

As described on the basis of exemplary embodiments and variants, embodiments of the connection module (for example the device circuit breaker) can implement a hold on the busbar module or modules (for example a distribution rail system) required for secure contacting of busbars. For this purpose, each connection module preferably comprises a pivot lever with a latch. For example, the pivot lever can comprise a resilient element (for example a spring leg or spokes) which applies a preload and / or a restoring force (or a corresponding torque) to the pivot lever. The bias and / or the restoring force can ensure the positive connection (for example the locking) of the connection module on the busbar module or modules.

The pivot lever can be monostable or bistable between an unlocked and a mounted position (and therefore, for example, are referred to as a latching lever).

The pivot lever preferably comprises a stamp. Optionally, during assembly (for example when plugging in) the connection module, the stamp can automatically move the pivot lever into the Move the assembled position for a positive locking by means of the bolt.

For convenient removal, an operating surface of the pivot lever can be actuated, whereby the pivot lever changes from the mounted position to the unlocked position. The stamp of the pivot lever can apply a mechanical repulsive force to the housing of the distribution busbar system, which leads to the separation of the electrical contacts. Thus, the greatest force has already been overcome when removing and the unlocked connection module (for example the device circuit breaker) protrudes a few millimeters from the distribution rail system, which makes it easier for the user to grasp the connection module for removal.
