Description

Technical Field

[0001] The invention relates to an electrical device according to the preamble of claim 1 . Background Art

[0002] Such electrical devices can be used, for example, in the field of automation technology, for example in industrial plants, for example in production plants. Such electrical devices can be installed, for example, in a switch cabinet and for this purpose can be arranged, for example, on a support rail inside the switch cabinet or on another fixing device. Such electrical devices can usually be combined with other electrical devices, for example, by arranging the electrical devices next to each other in order to provide electrical function groups for automation functions, for example for controlling actuators, for processing sensor signals and for potential distribution, for example for power supply.

[0003] The electrical device of the type described here comprises a first housing component and a second housing component having a housing wall. The housing components can be mounted to each other and locked to each other by a locking device in the position in which they are mounted to each other, so that the housing components are held on each other but can be removed from each other by unlocking the locking device.

[0004] In this electrical device, housing components should be able to be simply installed to each other and reliably and safely locked to each other in the installation position. Here, in the simple structural form of the locking device, the locking device should be easily and comfortably operated for unlocking.

[0005] In the electrical device disclosed by DE 197 10 768 C2, the base can be mounted on a support rail. The housing component can be connected to the base, wherein in the connected position there is an electrical connection between the base and the housing component, and the housing component is also locked relative to the base via a locking hook.

[0006] In the electrical device known from DE 197 44 662 C1, housing components can be mounted on one another and locked into one another in a connected position, wherein one of the housing components is fixed to a support rail and the other of the housing components can have a connection for connecting an electrical conductor, for example. Summary of the invention

[0007] The object of the present invention is to provide an electrical device which enables a simple, comfortable and reliable connection of housing components to one another, while securely holding the housing components in the mounted position to one another and making the release of the housing components from one another easy to operate.

[0008] This object is achieved by the subject matter having the features of claim 1 .

[0009] Therefore, the locking device has an operating element that is adjustably arranged on the second housing component along the operating direction and a locking element that is operatively connected to the operating element and adjustably connected to the housing wall. The locking element is configured to lock the first housing component and the second housing component to each other in the position where the housing components are mounted to each other. By adjusting the operating element relative to the housing wall along the operating direction, the locking element can be adjusted relative to the housing wall along an unlocking direction that is transverse to the operating direction to release the lock.

[0010] In the electrical device, the locking of the housing components in the mutually mounted position is established by a locking device, which has an actuating element arranged on the second housing component and a locking element also arranged on the second housing component. The locking element is used to establish the locking in the mutually mounted position of the housing components in that the locking element realizes an operative connection between the housing components and thus fixes the housing components to each other.

[0011] Here, the locking element is preferably able to automatically assume a position on the housing wall of the second housing component, which corresponds to the locking position, so that the locking element automatically locks when the housing components are mounted to each other, thereby automatically establishing a connection between the housing components when the housing components are mounted to each other.

[0012] By moving the locking element on the housing wall in an unlocking direction transverse to the operating direction when adjusting the operating element in the operating direction, the locking element can be unlocked by operating the operating element. In this way, the locking between the housing components can be cancelled, so that the housing components can be removed from each other and thus separated from each other.

[0013] In one embodiment, the locking element is integrally formed with the housing wall. The locking element can be formed, for example, as a tongue on the housing wall, wherein the locking element is preferably elastically adjustable relative to the housing wall. In the initial position of the non-actuated actuating element, the locking element assumes a position in which the housing components can be locked to one another by the locking element. Thus, when the housing components are mounted on one another, the locking device automatically locks, so that a safe and reliable connection is established between the housing components.

[0014] Since the locking element is integrally formed with the housing wall and thus with the second housing component, for example as a tongue, simple production is obtained, within the scope of which the locking element is produced together with the housing wall. The housing wall can be produced, for example, as a plastic molded part, for example by means of plastic injection molding, wherein the locking element is formed together with the housing wall in one working step.

[0015] In one embodiment, the locking element occupies a first position relative to the housing wall in the locked position and, for example, protrudes outward from the housing wall. By adjusting the actuating element, the locking element can be adjusted to an unlocked position, in which the locking element moves inwardly relative to the locked position along an unlocking direction. The locking element can be locked in a locked position when the housing components are mounted to each other, in which the locking element occupies such a position relative to the housing wall that the locking element can engage with a corresponding locking section on another first housing component when the housing components are mounted to each other, so that a lock can be established between the housing components in this way. By actuating the actuating element, the locking element can be adjusted out of the locked position, wherein in the unlocked position the locking element is adjusted inwardly toward the housing interior of the second housing component so that the locking connection between the housing components is canceled and the housing components can be released from their mounted position and removed from each other. Here, the adjustment of the locking element on the housing wall is carried out in an unlocking direction that is directed transversely to the actuating direction.

[0016] In one embodiment, the locking element is connected to the housing wall at one connected end. If the locking element is formed integrally with the housing wall, the locking element is formed integrally with the housing wall at the connected end and merges into the housing wall at the connected end. In particular, in the region of the connected end, the locking element can be elastically deformed for adjustment relative to the housing wall, so that the locking element can be adjusted relative to the housing wall by actuating the actuating element.

[0017] In the locked position, the locking element can be locked with the first housing component via an end edge facing away from the connection by virtue of the end edge lockingly engaging a corresponding locking section of the first housing component.

[0018] In one embodiment, the actuating element has a locking section which interacts with the end edge in the locked position so that the locking section blocks a movement of the end edge relative to the housing wall in the unlocking direction. The locking section of the actuating element thus serves to fix the locking element in the locked position so that the locking element cannot be easily moved out of the locked position, at least not without actuating the actuating element. This locking action can ensure a locked connection between the housing components. Furthermore, functional impairments, such as those caused by deformation or wear on the locking element, can be suppressed by the locking section.

[0019] In one embodiment, for locking, the locking section is preferably arranged behind the end edge (viewed in the unlocking direction) so that the locking section locks the movement of the end edge in the unlocking direction. Therefore, the locking section hinders the end edge, so that the adjustment of the locking element to the unlocking position is thereby resisted.

[0020] For example, the locking section is integrally formed on the operating element and is formed by an edge on the operating element. By adjusting the operating element, the locking section can be moved relative to the end edge of the locking element, so that when the operating element is operated, the locking section moves out of its operative connection with the end edge of the locking element and thus cancels the locking effect.

[0021] In one embodiment, a chamfer is formed on the locking section on the end face pointing opposite to the actuation direction, the chamfer being formed by a surface section on the end face that is shaped obliquely to the actuation direction and obliquely to the unlocking direction. The chamfer is used to simplify the establishment of an effective connection between the locking section and the end edge of the locking element when the actuating element is reset opposite to the actuation direction, in that the locking section can slide behind the end edge when the actuating element is reset opposite to the actuation direction, if necessary, when the end edge strikes the chamfer of the locking section.

[0022] In one embodiment, the operating element is guided on the second housing component in a linearly movable manner along the operating direction. Therefore, for operation, the operating element can be moved on the second housing component, thereby moving the locking element toward the housing wall and canceling the locking of the housing components with each other.

[0023] In one embodiment, the actuation direction in which the actuating element can be moved for unlocking the housing components from one another is directed opposite to the plug-in direction in which the second housing component can be mounted on the first housing component for connection. This makes it possible to release the locking device and remove the second housing component from the first housing component in one movement process, in that the user, for example, pulls the actuating element in the actuating direction to release the locking, thereby releasing the locking, and after releasing the locking, removes the second housing component from the first housing component in the actuating direction, i.e., opposite to the plug-in direction. This also makes the operation for unlocking and for releasing the housing components from one another easier, in that separate movement processes for releasing the locking and for separating the housing components from one another are not required, and this also makes it possible, in particular, to not need to keep the actuating element in a cumbersome manner in the unlocking position until the housing components are released from one another, but to release the locking and remove the housing components from one another in an intuitive, simple process. In particular, manual operation is also possible in this way.

[0024] The first housing component can be fixed, for example, on a support rail and for this purpose have a suitable fixing device for snap-locking connection with a support rail, for example a so-called top-hat rail. Here, the plug-in direction in which the second housing component can be mounted on the first housing component can point in the direction of the support rail, so that the second housing component can be plug-connected to the first housing component when the first housing component is connected to the support rail.

[0025] In one embodiment, the operating element has at least one action section, which is guided movably, in particular linearly, on at least one side edge of the locking element. For example, the operating element can have two action sections, which are guided, in particular linearly, on side edges extending parallel to each other, for example, on outer edges of the locking element that are away from each other or on edges of a gap of the locking element that face each other. The action sections can be configured, for example, as sliding sections, which can slide on the side edges and, when the operating element is operated, strike the side edges in the operating direction so that the locking element moves in the unlocking direction to unlock the connection between the housing components. Thus, the action sections achieve a redirection of the force of the movement of the locking element in the operating direction to the movement of the locking element in the unlocking direction oriented transversely to the operating direction, in that the action sections strike the side edges on the locking element when the operating element is operated and the locking element is thereby adjusted in the unlocking direction.

[0026] In one embodiment, a spring element is provided on the second housing component, which preloads the actuating element relative to the second housing component in the opposite direction of the actuation. Therefore, the actuation of the actuating element for unlocking the housing components from one another is performed against the spring preload of the spring element, which can be designed as a tension spring or a compression spring, for example. After the actuation is completed, the actuating element automatically returns to a non-actuated initial position due to the spring action of the spring element, in which the locking element assumes a locking position and can thus lock the housing components to one another when mounted on one another.

[0027] The spring element can be accommodated, for example, in a corresponding recess on the actuating element and can bring about a spring preload between the actuating element and the housing wall of the second housing component.

[0028] In one embodiment, the first housing component has a socket, which can be formed, for example, by a base housing that can be mounted to a support rail, and the second housing component can be inserted into the socket by a plug section. In the position in which they are mounted to each other, the plug section is accommodated in the socket so that the housing components are connected to each other.

[0029] The locking element can be formed on the plug section, wherein in this case the housing wall on which the locking element is arranged extends on the plug section and is formed, for example, by a longitudinal wall of the second housing component which is longer than the short wall of the end face of the second housing component.

[0030] In one embodiment, the first housing component has a wall facing the insertion opening and a latching section formed on the wall, for example in the form of a latching nose, with which the locking element engages in the position of the housing components mounted to each other for locking. When the housing components are mounted to each other, the locking element slides, for example, on the latching section and the collision slope formed therein, so that when the housing components are plugged into each other, the locking element automatically engages with the latching section for locking. In the locked position, the locking element engages with the latching section in a form-fitting manner, so that the housing components are thus fixed to each other against the plugging direction. By operating the operating element, the locking element can be disengaged from the latching section in an unlocking direction pointing transversely to the operating direction, so that the housing components can be released from each other again.

[0031] The housing components can be mounted to each other without the actuating element being actuated. To this end, the housing wall of the second housing component and / or the wall of the first housing component on which the latching section is formed have sufficient elasticity so that the latching element of the second housing component can move past the latching section of the first housing component when the housing components are mounted to each other even when the actuating element is not actuated, so as to engage with the latching section in a form-fitting manner.

[0032] In one embodiment, the actuating element has a head which is arranged in the region of the head side of the second housing component facing away from the plug section. Thus, the head of the actuating element is accessible from the side of the second housing component facing away from the plug section, so that the actuating element can be actuated by acting on the head and thus the locking between the housing components can be cancelled.

[0033] An electrical device of the type described above can in particular assume automation functions, for example within the scope of industrial plants or in the field of building automation. An electrical device of the type described above can be installed, for example, in a switch cabinet, wherein for this purpose, for example, the first housing component can be fastened to a support rail, so that the electrical device can be arranged entirely on the support rail and optionally combined with other electrical devices.

[0034] However, it is also conceivable to use the electrical device independently of the support rail, for example by fastening the electrical device to the wall of the switch cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] exist Figures 1 to 4 In the embodiment of the electrical device 1 shown, a housing component 14 in the form of a housing base is arranged on a support rail 2 by a fixing device 141 and is combined with other electrical devices of the same or different structural form on the support rail 2, for example along an arrangement direction A, so as to realize an electrical functional component in this way, which can, for example, undertake automation functions in the field of industrial equipment or building automation.

[0054] The housing assembly 14 constitutes a housing base, which may have, for example, a connection portion for connecting an electrical conductor. In the illustrated embodiment, a plurality of sockets 140 (four sockets 140 in the illustrated embodiment) are formed on the housing assembly 14, into which the modular housing assembly 10 may be inserted, so as to mechanically connect the housing assembly 10 to the housing assembly 14 and to electrically contact the housing assembly 14.

[0055] The housing components 10 can contain electronic devices, for example, so that different electrical and / or electronic functions can be provided in a modular manner on the electrical device 1 by mounting on the housing component 14 in the form of a housing base.

[0056] The housing components 10 each have a plug section 100 , with which the respective housing component 10 can be inserted along a plug-in direction E into a corresponding socket 140 on the housing component 14 in order to connect the housing component 10 to the housing component 14 in this way.

[0057] Each housing component 10 has a locking device 11, which is used to lock the housing component 10 with the housing component 14 in the position installed on the housing component 14, so that the housing component 10 is fixed relative to the housing component 14 in a form-fitting manner opposite to the plug-in direction E and is thus mechanically held on the housing component 14. The locking device 11 is releasable in order to remove the housing component 10 from the housing component 14 opposite to the plug-in direction E.

[0058] To form the locking device 11 , a locking element 13 is arranged on the housing component 10 , which is formed integrally and in one piece with the housing wall 101 of the housing component 10 and is in operative connection with an actuating element 12 which is movable in an actuating direction B relative to the housing wall 101 .

[0059] Reference Figures 5 to 15The actuating element 12 has an actuating head 120 which is arranged in the region of the head side 104 of the respectively corresponding housing component 10 facing away from the plug section 100, as for example by Figure 5 The head 120 is formed on a shaft section 121, which is formed at the end remote from the head 120 with a foot section 122, which is formed by arms 127, 128 and active sections 123, 124 formed on the arms, such as by Fig.11 visible.

[0060] The operating element 12 is guided linearly movably along the operating direction B on the housing wall 101, which is realized by the housing part 105 of the housing assembly 10 to be connected to the housing box. Via the effective sections 123, 124 of the foot section 122, the operating element 12 is operatively connected to the locking element 13 formed on the housing wall 101 in the region of the plug section 100, which is formed by Fig.11 As can be seen, it is integrally formed with the housing wall 101, for which purpose it is connected to the housing wall 101 at the connected end 135 and with the end edge 132 facing away from the connected end 135. The locking element 13 is arranged in the recess 103 of the housing wall 101 and can be elastically adjusted relative to the housing wall 101 in the opening 103.

[0061] like Figure 7 , Figure 8 and Fig. 9 , Fig.10 As shown, the effective sections 123, 124 of the actuating element 12 slide on the side edges 130, 131 of the locking element 13. Here, at the lower end of the side edges 130, 131 facing the end 135 of the connection, notches 133, 134 are formed on the locking element 13, which enable the actuating element 12 to be mounted while forming an effective connection between the effective sections 123, 124 and the locking element 13.

[0062] If according to Fig.12 and Fig.13 As can be seen from the sectional view, the locking element 13 is placed obliquely to the housing wall 101 in the locked position and points outward with its free end edge 132. In the locked position, the locking element 13 can establish a lock with the latching section 142 at the wall 143 inside the socket 140 of the housing component 14, in that when the housing component 10 is inserted into the corresponding socket 140 of the housing component 14 along the plug-in direction E, the locking element 13 hits the latching section 142 and engages with the latching section 142 after passing the latching section 142, as shown in particular by Fig.13Thus, in the locked position, when the housing components 10 , 14 are mounted on one another, a positive connection is established between the housing components 10 , 14 , so that the housing components 10 , 14 are fixed to one another counter to the plug-in direction E.

[0063] As this from Fig.12 and Fig.13 Combination Fig.11 It can be seen that the operating element 12 forms a locking section 125 on the foot section 122 between the arms 127 and 128, which blocks the locking element 13 in the locked position of the operating element 12, so that the locking element 13 is locked in the unlocking direction C. The locking section 125 is located behind the end edge 132 of the locking frame 13 in the unlocking direction C, so that the operating element 12 supports the locking element 13 opposite to the unlocking direction C and thus holds the locking element 13 in the locked position.

[0064] A chamfer is formed on the locking section 125 and is directed obliquely to the actuation direction B and the unlocking direction C. Due to this chamfer, when the actuation element 12 is adjusted to the locking position, the locking section 125 can hit the end edge 132, thereby providing support for the locking section 125 relative to the end edge 132 of the locking element 13.

[0065] The locking element 13 can be unlocked by actuating the actuating element 12 in the actuating direction B. When the actuating element 12 is actuated, the engagement sections 123, 124 are respectively formed with a chamfer 126 (see Fig.11 ) slides on the side edges 130, 131 of the locking element 13, and thereby elastically adjusts the locking element 13 inwardly relative to the housing wall 101 along the unlocking direction C, as in the case of Fig.12 , Figure 13 to Figure 14 , Fig.15 Therefore, as Fig.14 It can be seen that the end edge 132 of the locking element 13 is out of engagement with the latching section 142 on the wall 143 of the housing component 14 , so that the housing components 10 , 14 can be removed from one another counter to the plug-in direction E.

[0066] The actuation direction B along which the actuation element 12 is actuated for unlocking the locking device 11 points in the opposite direction to the plug-in direction E. To actuate the actuation element 12, the user can, for example, pull the head 120 of the actuation element 12 in order to move the actuation element 12 on the housing component 10 in the actuation direction B. The housing component 10 is then removed from the housing component 14 in the actuation direction B, so that the actuation of the actuation element 12 and the removal of the housing component 10 from the housing component 14 can be carried out in one movement and thus in one operation.

[0067] As in Fig.16 and Fig.17 As shown in the embodiment in FIG. 1 , the actuating element 12 can be spring-elastically prestressed relative to the housing component 10 by means of a spring element 136. For this purpose, the spring element 136 can be received, for example, in a recess 129 in the form of a receiving groove on the shaft section 121 of the actuating element 12 and supported with one end on a bottom 129A of the recess 129 at the transition to the foot section 122 and supported with the other end on a support section 106 which is formed on the housing part 105 and engages as a projection in the recess 129 in the form of a receiving groove.

[0068] In the exemplary embodiment shown, the spring element 136 is designed as a compression spring and pushes the actuating element 12 toward the locking position ( Fig.16 ) direction. When the operating element 12 is adjusted in the operating direction B to unlock, the spring element 136 is pressed ( Fig.17 The stress on the spring element 136 causes the operating element 12 to automatically return to the locked position against the operating direction B after the operation is completed. Fig.16 )middle.

[0069] This causes the operating element 12 to automatically return to its initial position corresponding to the locking position of the locking element 13 after the actuation is completed, that is, the operating element 12 is reset again against the actuation direction B after the actuation is completed.

[0070] Such a spring element 136 can be advantageous for simplified handling. However, such a spring element 136 can also be omitted. When the housing component 10 is mounted on the housing component 14 in the plug-in direction E, if the actuating element 12 is not in its initial position corresponding to the locking position of the locking element 13, the user usually presses the head 120 of the actuating element 12 and thus puts the actuating element 12 into a position corresponding to the locking position of the locking element 13.

[0071] By forming the locking element 13 integrally and integrally with the housing wall 101 and also by simply constructing the operating element 12 and being easily manufacturable, a locking device 11 having a simple structure is obtained, while achieving a reliable and fixed connection in the mutually mounted positions of the housing components 10, 14 and at the same time achieving simple and comfortable operation not only for connecting the housing components 10, 14 to each other but also for unlocking and releasing the housing components 10, 14 from each other.

[0072] The housing wall 101 of the housing component 10 and the wall 143 inside the socket 140 of the housing component 14 can be elastic transversely to the actuation direction B so that the housing component 10 can be plugged into the housing component 14 along the plug-in direction E even when the actuation element 12 is not actuated. In particular, the housing wall 101 can be shaped so that the locking element 13 can be inserted into the housing component 14 when the actuation element 12 is in a position according to the plug-in direction E. Fig.12 and Fig.13 In the initial position of the locking element 142 , the locking element 13 is offset so that the locking element 13 can move past the locking section 142 until the locking element 13 is locked with the locking section 142 .

[0073] The concept on which the present invention is based is not limited to the above-described exemplary embodiments but can also be realized in other ways.

[0074] A locking device of the type described can be used to connect completely different housing components to one another and is not limited in this respect to housing components to be connected to a housing base. A locking device of the type described can be used for locking in all positions in which the housing components are in a mutually mounted position with their walls facing one another so that a locked connection can be established by means of a locking element.
