The present application claims priority under 35 U.S.C. §371 to PCT Application PCT/EP2014/073573 filed on Nov. 3, 2014, which claims priority to German Patent Application No. 10 2013 112 101.2, filed on Nov. 4, 2013, the disclosures of which are hereby incorporated by reference in their entireties.
The present invention relates to a component assembly system comprising a supporting profiled rail and a bridging module for electrically connecting a functional component of the component assembly system.
Modern component systems in automation technology typically consist of a plurality of functional components arranged in a control cabinet. The energy and data distributing functions are realized by separate connector systems. Assembly without control cabinets is not possible since peripheral devices near the control cabinet hinge on a radial distribution of energy. If field bus concepts are used in which individual components are set onto backplanes, the backplanes are subject to high forces of weight.
Bridge elements can be used to electrically connect functional components. They are not, however, associated with any further mechanical functions.
Printed publication DE 30 30 906 A1 relates to a switching bridge plug. The switching bridge plug comprises two conductive bridges each having two connector pins in respective pairs parallel to one another at the spacing of the pins in a common plug part made of insulating material for conductive paths on a printed circuit board.
The task underlying the invention is that of specifying a component assembly system able to simplify the assembling of the components.
This task is solved by the subject matter features according to the independent claims. Advantageous embodiments of the invention form the subject matter of the figures, the description and the dependent claims.
According to one aspect of the invention, the task is solved by a modular component assembly system having a supporting profiled rail and at least one bridging module for electrically connecting a functional component of the component assembly system which comprises a module locking device for latching the bridging module onto the supporting profiled rail. This for example thereby achieves the technical advantage of having the same mechanical configuration on the supporting profiled rails for connectivity and functional components, dispensing with wiring for all the system's voltages and the control bus as well as any further manual interconnections there may be. Fixing the assemblies ensues by locking options both at the starting point of an assembly's bridging module as well as at the individual functional components.
The component assembly system can for example be a field bus system.
The module locking device is an embodiment of a form-locking connection for positively connecting the bridging module to the supporting profiled rail. In the embodiments described below, the module locking device can thus be generalized as a form-locking connection, wherein the interlocking is an embodiment of said form-locking connection.
In one advantageous embodiment of the component assembly system, the bridging module comprises a receiving groove for the insertion of an operational section of the functional component in order to absorb tensile forces of the functional component along the supporting profiled rail. The receiving groove achieves for example the technical advantage of preventing tensile force-related damage to the plug contacts.
In a further advantageous embodiment of the component assembly system, the module locking device comprises a rigid seating section extending around the supporting profiled rail and an elastically flexible latching section opposite the rigid seating section for locking onto the supporting profiled rail. The bridging module can thereby be pivotably latched to the supporting profiled rail.
The elastic latching section can be designed to overlap the supporting profiled rail on the side. This for example thereby achieves the technical advantage of the latching means being able to engage at the rear of the supporting profiled rail and create a stable connection.
In a further advantageous embodiment of the component assembly system, the latching section comprises a latching lug to engage behind the supporting profiled rail. This for example thereby achieves the technical advantage of being able to easily latch and secure the bridging module to the rear of the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the latching section is integrally formed on the bridging module. This for example thereby achieves the technical advantage of the bridging module being able to be produced together with the latching means in one production step.
In a further advantageous embodiment of the component assembly system, the latching section comprises a recess for increasing the flexibility of the latching section. This for example thereby achieves the technical advantage of the latching section being able to flexibly bend when being latched on even though the bridging module is formed from a relatively rigid material.
In a further advantageous embodiment of the component assembly system, the bridging module comprises a rail slot for inserting an edge of the supporting profiled rail. This for example thereby achieves the technical advantage of being able to hang the bridging module in the intended position on the supporting profiled rail from the rail slot.
In a further advantageous embodiment of the component assembly system, the rail slot is arranged on one end face of the bridging module and the module locking device is arranged on an opposite end face of the bridging module. This for example thereby achieves the technical advantage of being able to first hang the bridging module on the supporting profiled rail and then lock it on with a rotational motion.
In a further advantageous embodiment of the component assembly system, the module locking device is centrally arranged on one or two opposite end faces of the bridging module. This for example thereby achieves the technical advantage of forces being transferred evenly from the bridging module to the supporting profiled rail. Both seating and pivoting into position is possible from the end face or the rear side of the module bridge, as is also a direct linear seating and joining of the modular bridge to the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the bridging module comprises a centering section for centering the bridging module on the supporting profiled rail. This for example thereby achieves the technical advantage of being able to easily seat the bridging module in the intended position and additionally being able to stabilize it on the supporting profiled rail by way of the centering section.
In a further advantageous embodiment of the component assembly system, the module locking device comprises a pocket for the insertion of a tool to bend the module locking device upward. This for example thereby achieves the technical advantage of being able to easily remove the bridging module from the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the pocket is situated on the latching section opposite the latching lug. This for example thereby achieves the technical advantage of directly transferring the forces exerted on the pocket to the latching lug and being able to remove the bridging module with little effort.
In a further advantageous embodiment of the component assembly system, the pocket is formed by a balcony section projecting from the latching section. This for example thereby achieves the technical advantage of the pocket being able to be integrally and stably formed by the balcony section.
In a further advantageous embodiment of the component assembly system, the inadvertent opening, upward bending and disengaging of the module locking device when assembled with the functional component is prevented by an obstructive overlapping of a functional component housing.
In a further advantageous embodiment of the component assembly system, the bridging module comprises a dovetail slot for laterally fixing the bridging module to a terminal block. This for example thereby achieves the technical advantage of being able to easily fix the bridging module laterally.
In a further advantageous embodiment of the component assembly system, the bridging module comprises a locking device for non-displaceably locking the bridging module to the supporting profiled rail. This for example thereby achieves the technical advantage of increasing the stability of an assemblage of elements on the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the component assembly system comprises a functional component, wherein the functional component has a functional component bottom part able to be set onto the bridging module and a functional component upper part able to be set onto the functional component bottom part, and wherein the component assembly system can be laterally extended by a second functional component via the bridging module.
In a further advantageous embodiment of the component assembly system, the functional component upper part forms a connection interface for the functional component bottom part and a further connection interface for a further functional component upper part attachable onto the functional component upper part.
In a further advantageous embodiment of the component assembly system, the functional component bottom part comprises a component securing device for holding the functional component on the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the bridging module and/or the functional component (400) is/are displaceable on or along the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the functional component bottom part and the bridging module are connectable in a form-fit connection to absorb the tensile forces acting on the connection between the bridging module and the functional component bottom part along the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the bridging module comprises a dovetail slot for laterally fixing the bridging module to a terminal block.
In a further advantageous embodiment of the component assembly system, the component assembly system comprises a terminal block for fixing the bridging module against displaceability on the supporting profiled rail, wherein the terminal block is connectable to the bridging module.
In a further advantageous embodiment of the component assembly system, the terminal block is friction-lock or form-lock connectable to the bridging module, particularly by means of a T-slot/groove connection, a dovetail connection, a screwed connection or a clamped connection.
In a further advantageous embodiment of the component assembly system, the terminal block is designed to positively engage around and/or frictionally clamp the supporting profiled rail.
In a further advantageous embodiment of the component assembly system, the terminal block has an externally conducting grounding terminal which is electroconductively connectable to the supporting profiled rail.
Further embodiments of the invention are depicted in the drawings and will be described in greater detail below. Shown are:
Different embodiments of the structural concept can be realized depending on the intended application. The structural concept is infinitely extensible. The internal electrical connections for energy distribution of for example 400V or 24V and the data bus are realized simultaneously with plugging the components together. The connecting functions are realized in the functional component bottom part 421-2 of functional components 400 and the bridging modules 300 by bridging plugs 305. The supplying, shielding, switching functions result from the sequential arrangement of the functional components 400. The application functions, such as for example supplying, shielding and switching, are realized in the functional component upper part 421-1 which is connected to the functional component bottom part 421-2 by plug contacts.
The functional component upper part 421-1 has a defined mechanical and electrical interface with the functional component bottom part 421-2 and can also be used with other functional component bottom parts 421-2 having the same interface. The functional component bottom part 421-2 only incorporates the connection system. The separating, shielding or switching functions, for example, are incorporated in the functional component upper part 421-1. The direction of action of the above-cited functions is effected in the line and/or in the load outflow dependent on the functional component upper part 421-1 and the functional component bottom part 421-2; i.e. a plug connection in the functional component upper part 421-1. The connectivity can be disengaged in the functional component bottom part 421-2.
The supporting profiled rail 200 forms a one-piece supporting system with a wide rail for a rack mount which emulates the geometry of the supporting edges of the bridging module 300 and the functional components 400. Alternatively, two separate standard supporting profiled rails can be used as a two-piece supporting system, e.g. 35 mm wide, for a wall mount. The supporting profile can be formed by a top-hat profile.
The mounting direction of the bridging module is perpendicular to the plane spanned by the supporting profiled rails 200. The functional components 400 each comprise one or more component securing devices 401 for fixing the functional component 400 to the supporting profiled rail 200. A terminal block 103 is situated on the left side of the assemblage.
When a left bridging module 300 is mounted, a left arm of the functional unit runs flush with the left bridging module 300 upon assembly. The right arm pushes the right bridging module 300 to its limit on the base of the functional housing of the functional component 400. The left arm thereafter clips the functional component 400 to the two connector faces of the bridging module 300. The mechanical positioning of the functional components 400 in the remote location is generally unrestricted. The line's arrangement and sequence determine function.
The bridging module 300 comprises a functional component bottom part 331, a functional component upper part 333 and not-shown housing sealings as well as a seal 327, e.g. with a sealing when remote or without a sealing in a control cabinet. Notches/screws/pressure/welding/adhesive provide a housing connection. The electrical structure of the bridging module 300 provides connections for low and extra-low voltages. To this end, conductors or plugs of curved round wire or as punch-formed parts or as feeder rails of stamped sheet metal with contacted connector pins and connectors on a passive or active board for a data bus connection are provided within the bridging module 300. The bridging module 300 with different plug gaps is provided in order to create specific clearances between the functional components.
At the front, the bridging module 300 has two protruding connector sections 321 which form the connector face. A right and a left functional component 400 are in each case fitted onto the connector sections 321. The connector sections 321 have a circumferential seal 327 so as to form a sealing system for the fitted functional components.
The bridging module 300 has a respective receiving groove 303 on each of the transverse sides for insertion of an operational section of a right-mounted or left-mounted functional component 400 in order to absorb tensile forces of the functional component 400 along the supporting profiled rail 200. The operational section of the functional component 400 and the receiving groove 303 produces a positive connection between the functional component 400 and the bridging module 300, thereby preventing tensile forces from damaging the connector section 321.
To mechanically uncouple the float-mounted electrical plug connections of bridging modules 300 and functional components 400, a higher-level mechanical pre-centering occurs. This ensues by a rib arranged above and below the connector assembly in functional component 400 mechanically engaging in the corresponding receiving groove 303 in the bridging module 300 and respectively fitting in the end position in the x and y direction.
Doing so thus mechanically decouples the forces acting in the x and y direction on the electrical plug connection. Drawing forces of the functional components 400 in the z direction are decoupled by appropriate locking slides situated in the functional components and engaging behind the supporting profiled rail. There is thus a mechanical blocking of all the possible degrees of freedom between the bridging modules 300 and the functional components 400 in the mounted state.
The bridging module 300 additionally comprises a module locking device 301 on one of the transverse sides for latching the bridging module 300 onto the supporting profiled rail 200. The module locking device 301 is formed by an elastic latching section 311 which overlaps the side of the supporting profiled rail 200 after the bridging module 300 is seated. The latching section 311 has an elongated recess 313 which extends along said latching section 311 to increase the flexibility of the latching section 311. The bridging module 300 can thus be formed as a single piece from a rigid plastic without the latching section 311 being too rigid.
A protruding balcony section is formed at the end of the latching section 311 as pocket 315. The pocket 315 serves for the insertion of a tool, e.g. a screwdriver. The latching section 311 can be outwardly bent by tilting the tool sideways so that the bridging module 300 can be separated from the supporting profiled rail 200.
A protruding centering section 317 is situated on the rear of the bridging module 300 which additionally stabilizes and supports the bridging module 300 on the supporting profiled rail 200. To this end, the upper and lower side of the centering section 317 respectively abut against the upper or lower supporting profile of the supporting profiled rail 200.
The bridging plug 325 comprises a plurality of electrical connections for the parallel or serial transmitting of data signals between the functional components 400. This thus enables a data bus to be realized between the functional components 400. The bridging plugs 305 and 325 are accommodated by the bridging module 300 and form an internal wiring. The bridging plug 325 is exchangeable so that a bridging module 300 with exchangeable component assemblies for different data bus variants results.
A rail slot 307 is provided on the opposite side for the insertion of an edge 203 of the supporting profiled rail 200. The rail slot 307 is formed within a U-shaped seating section 323 which engages around the edge 203 of the supporting profiled rail 200 and is integrally formed on the bridging module 300. The seating section 323 is arranged on the transverse side of the bridging module 300 opposite the transverse side with the module locking device 301. Two dovetail slots 319 are situated on the longitudinal side of the bridging module 300 for laterally fixing the bridging module 300 to the terminal block 103.
The bus termination can alternatively be formed by a conventional bridging module 300 having two connector sections 321, with a cap piece placed on the unused connector section 321 as an attachable contact protection.
The bridging module 300 is the key connecting element in the structural concept of the housing of the component assembly system 100 which assumes the electrical connections between the functional components 400 and, together with the supporting profiled rail 200, represents the connection to the conventional structural design technology. Generally speaking, the bridging module 300 can be configured as a floating bearing, which is only fixed to the supporting profiled rail 200 by latching and is displaceable, or as a fixed bearing having a metallic clamping arrangement and PE contacting.
Greater distances between the functional components 400 serve in the additional lateral circulation around the functional components 400 in order to improve cooling and create space for cable lead-throughs and feeds as well as improve accessibility upon greater line density. Lesser distances between the functional components 400 result in a compressing of the overall system dimensions and an overall more compact design.
The fixed-bearing grounding module 600 fixes the entire system to a fixed point on the supporting profiled rail 200 in the x direction. With this configuration, the system structure can freely distend in the x direction from a fixed point, such as for example upon a thermally-induced longitudinal expansion. The mechanical clamping of this fixed point is at the same time the central electrical grounding and connection to the supporting profiled rail of the system assembly.
The functional component bottom part 403 and the bridging module 300-1/300-2 are respectively positively connectable, e.g. by way of a tongue-and-groove connection. The functional component bottom part 403 comprises for example a protruding operational section 413, e.g. a spring, on the underside for insertion into a receiving groove 303 of the respective bridging module 300-1 and 300-2 in order to absorb tensile forces of the functional component bottom part 403 along a supporting profiled rail 200. The functional component bottom part 403 of the functional component 400 is fixed to the supporting profiled rail 200 by a component securing device 401, e.g. a snap-lock connection.
A circumferential notch 411 is formed on the upper side of the functional component bottom part 403, into which an annular sealing element 407 can be inserted. The sealing element 407 seals the gap between the functional component bottom part 403 and the functional component upper part 405. Depending on the sealing element 407, different types of protection from IP20 to IP6x can be realized. A plurality of projecting connector plug sections 409 forming a connector face can additionally be formed on the upper side of the functional component bottom part 403. The connector plug sections 409 form an interface for the electrical and mechanical connection of the functional component upper part 405.
A contact block 415 having a plurality of terminals is situated within a functional component upper part 405 for connecting individual electrical conductors such that the functional component upper part 405 has a distributor function. The functional component upper part 405 comprises a cover 417 without an electrical connector unit which is seated together with the sealing element 419. The sealing element 419 is fixed to a frame-shaped housing section 425 of the functional component upper part 405 by means of the four screws 421. The functional component upper part 405 is screwed to the functional component bottom part 403 by means of screws 423.
The functional component bottom part 403 enables unlimited stacking of the functional component upper parts 405. All in all, the functional component bottom part achieves a repeatable combination of electric plug connection and mechanical housing assembly.
The component locations can be used as conventional star distribution end devices by employing a simple feed-in or as an energy distribution network by employing a connector and distributor module (AV module) to subscribers or nodes. Switching and protective elements, motor switches, bus couplers, or I/Os, etc., can be arranged to the left and right of the AV module in any unrestricted, functionally determined order. Doing so achieves engineering advantages based on the visible separating of low and extra-low voltage components. Multiple remote locations can span a network as a subscriber in any structure such as e.g. linear, tree or ring.
The configured range of energy distribution output no longer requires a central control cabinet. By suitably configuring the accompanying data bus, the order and positions of the remote location's individual components can be checked prior to putting the design-conformant arrangement into operation (remote putting into service, remote service).
The component assembly system 100 enables an assembly of “smart” installation networks for direct and alternating current and cabinet-free distribution in applicable system layouts. The component assembly system can be used in installation or energy distribution fields of application. In distributed automation, an assembly of modular remote locations as functional nodes in “smart” installation networks is possible. In alternative control cabinet concepts, an assembly of modular units in a control cabinet without conductor rails and without control wiring is possible with identical design for IP20 . . . IP6x.
The component assembly system 100 enables the development of remote modular motor switches of high protection class. The component assembly system 100 additionally develops a comprehensively integrated system concept (power & drive, P&D) which solves the task of advantageous remote energy distribution and supply, e.g. external of a control cabinet.
The modularity of the component assembly system 100 enables the expansion of the application beyond the modular remote location to “smart” energy distribution through to an alternative control cabinet design. Covering the spectrum of stand-alone functional components as end devices in a conventional star-shaped energy distribution can additionally be achieved. The component assembly system 100 enables a flexible remote assembly of modular systems (IP6x) and within or external of a control cabinet on standard supporting profiled rails (IP20). In a pre-assembly case, pre-wiring can be performed on an assembly block.
All of the features defined and depicted in conjunction with individual embodiments of the invention can be provided in various combinations in the inventive object in order to realize their advantageous effects simultaneously.
