Definitions
- the invention relates to a housing suitable for enclosing an electromechanical component and a housing arrangement.
- the housing it is important that it is itself robust, which means that the encased component is well protected. Furthermore, it is necessary for the housings to be installed in a device or in an assembled component in a robust manner.
- Contactors usually represent electromechanical safety components in circuits in which high currents of up to 1000 A and, in particular, voltages in the range of around 1000 V and, for example, up to a maximum of 1500 V are present.
- Contactors are usually connected to a load circuit by means of suitable contacts.
- Contactors can be remotely operated switches that can be switched on and off via a control circuit, which is a second power or signal line circuit on the contactor.
- a common combination is, for example, that a contactor is used in combination with a fuse between a battery and an electric motor.
- the battery can be a lithium-ion battery, for example.
- a housing arrangement is described with a housing which has a plug-in side and encloses an electromechanical component and which is provided for mounting on a carrier. Further in accordance with this present aspect, the housing includes a first mounting guide adapted to engage a slot guide disposed on the carrier, by means of which engagement the mating side of the housing can be guided into a mating position on the carrier.
- the carrier can have a box-like shape, for example.
- a printed circuit board or circuit board can be arranged on the carrier.
- the printed circuit board or circuit board can be part of the carrier.
- the housing in the plugged-in position is preferably placed on a slot on the carrier or on a circuit board on or in the carrier.
- a connection in the slot can be an electrical connection between a connection in the slot and the electromechanical component.
- the inventors of the invention have found that the insertion of a housing into a carrier can be made significantly easier if a mounting guide is arranged on the housing, which engages in the slot guide.
- the housing can be brought close to the slot or mating position. In particular, it can be brought into a pre-plugged position, in which this pre-plugged position the assembly guide begins to engage in the slot guide.
- the housing can now easily be brought into the plugged-in position along an insertion direction via the guide formed in this way.
- assembly management and slot management can increase the stability of the housing arrangement.
- the mechanical stability can be improved with respect to forces acting perpendicularly to the direction of insertion.
- a positioning accuracy in the plugged-in position or a positioning accuracy on a slot of up to 0.2 mm, and in some cases even less can be achieved.
- a positioning accuracy can be sufficient to plug a plug into a mating plug for electrical contacting.
- the housing can be approximately cuboid.
- the shape can deviate from that of the perfect cuboid shape. For example, corners or edges can be rounded.
- the housing can have areas, parts or other components protruding from a cuboid core.
- the first mounting guide is shaped in a complementary manner to the first slot guide.
- Complementary can be understood in such a way that the shapes of the assembly guide and the slot guides fit together or into one another.
- they can be shaped like positive or negative to each other.
- the positive or negative form does not have to be completely executed.
- the respective shapes can also have interruptions or, for example, not be solid in terms of material.
- the mounting guide and the slot guide are shaped to complement each other, the precision of the guide can be supported.
- the first assembly guide is arranged on a side which lies laterally to the plug-in side of the housing.
- the assembly guide is preferably arranged on a side of the housing which is neither the mating side itself nor a side opposite the mating side, which can be referred to as a base side of the housing.
- the mounting guide preferably extends in the direction of insertion.
- the direction of the mounting guide is preferably oriented in the direction of insertion and thus preferably perpendicular to the orientation of the plug-in side of the housing. This facilitates or enables insertion in the plugged-in position.
- the mounting guide can be in the form of a rail.
- the slot guide complementary thereto can thus preferably be designed in the form of grooves, with the rail shape preferably fitting into the groove shape.
- the assembly guide can have an insertion bevel, for example, at that end which is closest to the plug-in side, ie it can be bevelled. This can make it easier for the mounting guide to engage in the slot guide.
- the mounting guide can also be rounded off, or its shape can support easier access to the slot guide in a similar way.
- the first assembly guide forms a projection. This can mean, for example, that the first assembly guide protrudes from the side surface on which it is arranged.
- the shape of the complementarily shaped slot guide is preferably an elongated indentation.
- the housing has a second mounting guide on a further side face lying laterally to the plug-in side of the housing.
- This second assembly guide is also intended and suitable for engaging a second slot guide.
- the second slot guide is preferably also arranged on the carrier.
- a second mounting guide which is arranged on a different side surface than the first mounting guide, has the advantage that the housing can be fixed on two side surfaces. Thus, the precision when inserting into the slot can be increased.
- the plug-in position itself can also be defined more precisely.
- the mechanical stability can also be increased, in particular in directions perpendicular to the direction of insertion, by the second assembly guide and slot guide.
- This advantage is particularly pronounced when the second assembly guide is arranged on a side face of the housing opposite the first assembly guides.
- an assembly guide is provided or arranged on each side surface of the housing lying laterally to the plug-in side. This is suitable in each case for engaging in a suitable slot guide, which is preferably arranged on the carrier.
- a first, a second, a third and a fourth mounting guide can therefore be arranged on the housing on a side surface lying laterally to the plug-in side, if one assumes a cuboid housing. If the housing has a plurality of side surfaces located laterally to the plug-in side of the housing, additional ones can also be used analogously
- Mounting guides can be arranged on the housing.
- a corresponding number of slot guides is preferably provided on the carrier.
- two openings for passing through electrical contacts or contact elements can be arranged on a side surface of the housing.
- a mounting guide ie one of the first or a further mounting guide, can preferably be arranged between the openings, which is provided and designed to form electrical shielding of the contact elements in the area between the openings.
- the contact elements can be the load circuit contacts of a contactor.
- one of the assembly guides can serve as a shield located between the electrical contacts.
- This can, for example, be a shield when connecting or making electrical contact with such contacts if the connections are already live when making contact.
- Such a shield can also shield contacts or connections that have been stripped of their insulation during operation, for example to prevent flashovers.
- the lines which are attached to the corresponding contacts in a contactor can preferably be characterized in such a way that voltages of over 1000 volts and currents of over 500 amperes are applied to them. This means that outputs between 50 kilowatts and over 500 kilowatts can be applied to them
- an electrical plug can be arranged in the plug-in side of the housing. Furthermore, the electrical connector makes contact with a mating connector on or in the carrier.
- the housing can preferably be guided into the plugged-in position, with the plug simultaneously engaging electrically in the mating plug and an electrical contact being able to be established in this way.
- the connector and the mating connector can preferably be part of a control circuit of a contactor or another electromechanical component which is housed in the housing.
- the electromechanical component is preferably electrically connected to the plug, so that the electromechanical component is electrically contacted during installation.
- the housing has the base side opposite the plug-in side.
- attachment points can be arranged, for example, on parts protruding from the base page, the Attachment points are intended and suitable to be attached by means of a screw on the carrier.
- the screwing can be carried out, for example, on a retaining bolt which is arranged in the carrier.
- the screw connection allows the housing to be attached to the carrier in a stable manner in all directions.
- At least one external fine guide element can be arranged on the mating side or in the mating side.
- Such an external fine guide element can preferably be arranged in the vicinity of or directly on a plug as described above.
- the outer fine guide element is provided for engaging in a first fine positioning element arranged on the carrier.
- the fine positioning element is preferably arranged on the slot.
- the plug-in side of the housing can be positioned even more precisely on the carrier in the plug-in position by means of this last-described engagement of the outer fine guide element in the fine positioning element.
- an external fine guide element can be provided, which guides the mating side precisely into the mating position during insertion, for example over the last few millimeters of insertion in the direction of insertion.
- guidance accuracies of well below 0.2 mm, for example 0.1 mm or less, can be achieved.
- a method for assembling the housing arrangement is specified.
- the housing is first brought into a pre-plugged position in which the assembly guide begins to engage in the slot guide.
- This insertion into the pre-inserted position can be done manually or by an appropriate insertion machine, for example.
- the housing can then be pushed along an insertion direction under the guidance of the interlocking mounting guide and the slot guide into the plugged-in position.
- the method for assembling a housing can preferably be carried out in such a way that the direction of insertion is oriented in the direction of gravity.
- the housing is therefore preferably oriented downwards with the plug-in side first, that is to say in the direction of gravity. In this direction it is also used in an insertion process. This means that the direction of gravity is preferably the direction of insertion.
- a housing for accommodating an electromechanical component having a first housing component and a second housing component is described as a further aspect.
- the inclusion of an electromechanical component can be a housing, ie z. B. a one or enclosing, the electromechanical component.
- the second housing component has a first guide groove.
- the first housing component has a first complementary element.
- the first complementary element and the first guide groove are designed in such a way that the housing components can be or are connected to form a housing by being pushed into one another along a guide direction.
- the housing is particularly preferably a contactor housing, ie a housing which is intended and suitable for enclosing a contactor as an electromechanical component.
- the case may be composite, but need not be composite.
- the first and second housing components, which together form the housing, can also be unassembled, but are in any case suitable for being assembled.
- the housing can include more than two housing components. Preferably, it mainly comprises the first and second housing components.
- the first and second housing components can each be a first and a second housing half.
- the first complementary element preferably fits into the guide groove.
- the first guide groove can have any shape.
- the guide groove may be scored in the material forming a side surface of the second housing component.
- the mold can also have undercuts. This means that the shape can be, for example, wedge-shaped, trapezoidal, T-shaped or L-shaped in terms of its cross section. In this case, this shape is preferably formed or dug into the material that forms a side surface of the second housing component.
- the complementary element has a shape that matches the guide groove.
- the complementary element can have a rail-like shape. This means that the complementary element can be guided in the guide groove like a rail. However, this does not necessarily mean that the complementary element has to be longer in the guiding direction than it is wide perpendicular to the guiding direction. For example, it can also be wider than long.
- the guide groove and/or the complementary element can have a stop that limits the positions of the housing components relative to one another.
- a stop can be ensured, for example, by the housing components hitting one another in a specific position, thereby preventing further pushing together in the guide direction.
- the stop can also be part of the guide groove.
- the stop can be an end of the guide groove beyond which the complementary element cannot be guided in the guide direction.
- the guide groove or the complementary element or both can comprise a latching or clamping element which can offer a certain stability in the guide direction.
- securing or stabilization in the guiding direction is preferably achieved by the measures described below.
- a particularly stable connection between the two housing components can be achieved.
- a significantly more stable connection can be achieved than when two-part housings are connected to one another, for example, solely via unstable latches.
- the housing can be particularly resistant to the effects of force perpendicular to the guide direction in the assembled state due to the guide groove and the complementary element. Furthermore, the housing can also be particularly resistant to torsion or twisting about an axis parallel to the guide direction. In addition, this housing configuration can enable simple and uncomplicated assembly of the housing components or enclosing the electromechanical component. According to the aspect described above, the two housing components only have to be pushed together around an electromechanical component to be protected.
- This encapsulation can thus be simpler than with multi-piece housings in which the housing components have been potted with a resin or other filling material together with a component to be encapsulated.
- a significantly lighter composite of the housing and the component to be housed can be achieved in this way than can be achieved in the case of casting.
- a synergetic effect can thus also be achieved with the aspects described for the housing arrangement, since both a stable housing and also stable installation in a housing arrangement can be facilitated or guaranteed.
- connection of the housing components is non-positively perpendicular to the guiding direction. Even more preferably, the connection is non-positive in all directions perpendicular to the guiding direction. This can mean, for example, that the two housing components can only be assembled or pushed together or apart along the guide direction, at least as long as no other components are arranged on the housing that prevent this. In this case, in at least one or preferably in all directions perpendicular to the guide direction, a moving apart of the housing component can be restricted by the mating of the complementary element in the guide groove.
- the non-positive connection can be supported in particular by the shape of the guide groove and the shape of the complementary element that complements it, or can be provided by this shape.
- a complementary shape can be understood to mean that the shapes essentially fit into one another in a form-fitting manner.
- the shape of the guide groove and the shape of the complementary element do not necessarily have to behave like positive and negative, but they can.
- the complementary element could have interruptions in its shape in the guiding direction.
- the complementary element could have a wing-like design, with the wings engaging in undercuts.
- the guide groove can also be formed only in parts along the guide direction, for example as a type of clamps into which the complementary element engages.
- a second guide groove and a second complementary element can also be contained in the housing or the housing can have them.
- the second complementary element is provided and suitable for being pushed into the second guide groove or, equivalent to the first guide groove and the first complementary element, to engage in one another.
- the two complementary elements are preferably arranged on the first housing component and the two guide grooves are arranged on the second housing component.
- the second complementary element preferably fits into the second guide groove.
- the second guide groove and the second complementary element are preferably shaped and arranged on the housing in such a way that when the two housing halves are pushed together with the aid of the first guide groove and the first complementary element, they can be pushed together at the same time, with the second complementary element fitting into the second guide groove can grip.
- the second guide groove is preferably arranged on the first housing component in exactly the same way as the first guide groove.
- the second complementary element is preferably also arranged on the first housing component. If two guide grooves are formed with two complementary elements, these can, for example, be arranged symmetrically to a plane of symmetry or an axis of symmetry of the housing.
- the housing has a safety device or a safety device is arranged on it, this safety device causing a fixed connection of the first and second housing components in the guide direction.
- a set of individual components can be regarded as a housing, which together form the housing, ie the housing here comprises the first housing component, the second housing component, and elements which serve as a safety device. These do not have to be assembled here.
- the aforementioned preferred aspect has the advantage that the housing components are firmly connected to one another at the end of the assembly process, for example in a non-positive manner, also in the guide direction. This means that the safety device synergistically complements the connection of the housing components through the guide groove and the complementary element.
- Safety device can be realized, for example, by two or more safety elements or the safety device can comprise two or more safety elements.
- the security device may consist of two or more security elements.
- these two or more securing elements can be elongate tenons inserted, for example, into overlapping side surfaces of the two housing components in a direction perpendicular to the guiding direction.
- it can be rivets, pins, but also screw connections or nails.
- These security elements are preferably metallic.
- they can contain the materials steel, bronze, or aluminum.
- the security elements can also contain alloys of these materials, in particular those with a mechanical stability similar to that of steel.
- the security elements can also include materials of the housing, for example they can include the plastic.
- the security elements can also consist of these substances.
- the securing elements comprise at least one hollow sleeve, which is arranged in aligned holes in the first and second housing components.
- the securing elements can be designed as one or more hollow sleeves, the first housing component having holes which are aligned with corresponding holes in the second housing component and the one or more hollow sleeves being arranged in these aligned holes.
- the hollow sleeves are preferably made of metal and can have a round or an oval cross section.
- they can also be hollow rivets.
- the hole-shaped openings formed in this way on the housing can serve as attachment points to which the housing is attached externally.
- the holes or the attachment points can be arranged on a base side of the housing.
- the holes are preferably arranged in an overlapping area of the first and second housing components, which can also be referred to as an overlapping area. More preferably, these are arranged on wing-like components of the first and second housing components that protrude from the main body of the housing.
- a screw connection can be made at the attachment points formed in this way, for example.
- screws or threaded pins can be passed through them, which either fasten the housing directly with the base side lying on a fastening element or with the plug-in side, which is usually opposite the base side, on a slot.
- a synergetic effect can thus be achieved in that the securing elements are used both for securing, ie for firmly connecting the first and second housing components in the guiding direction, and as attachment points for external attachment of the housing.
- the housing has at least one latch.
- the first and the second housing component are preferably assembled. The first housing component and the second housing component are locked together by means of the locking mechanism.
- the second housing component has a latching element which comprises a resilient or bendable part and a hook-shaped part.
- This hook-shaped part can, for example, engage in an opening in the first housing component.
- catches can also be provided or arranged on the housing in an analogous manner.
- the latch can be arranged on any part of the housing. Respectively, the parts of the latch which engage in one another can be arranged on the respective housing components in such a way that they can engage in one another.
- the latching can bring several advantages.
- the latching can serve as additional stabilization or attachment of the two housing components to one another in the guide direction in addition to or instead of the safety device.
- the latching can also represent a depth stop in the guide direction, in that the first housing component is fixed in relation to the second housing component by latching in a specific position relative to one another.
- the holes can be aligned with one another, in which case the safety device, for example, can be inserted into the holes.
- such a latching can make it more difficult or prevent the housing components from slipping relative to one another during installation or afterwards.
- the at least one catch or the plurality of catches is arranged on a side of the housing opposite the guide groove.
- the catch or the catches can preferably be arranged on a side of the housing which is opposite a side of the housing in which the first guide groove is arranged.
- a particularly stable connection of the housing halves to one another can be achieved by the opposite attachment of the catch and the guide groove with the complementary element engaging in this. By arranging them opposite one another, the housing components on the plug-in side can be prevented from opening up under load.
- the housing has openings which are arranged on the housing in such a way that they are suitable for leading electrical contacts in the guide direction from the inside of the housing to the outside.
- These electrical contacts can be the load circuit contacts of a contactor, for example.
- the openings can be arranged, for example, on a side face of the housing which is oriented perpendicular to the guide direction.
- the contactor or another electromechanical component could then be placed in the second housing component and the first housing component can be pushed onto the second housing component around the electromechanical element to be protected in the guide direction.
- load circuit contacts can then pass through the openings to the outside. Contact can then simply be made at these without an additional step of routing load circuit lines to the outside being necessary.

- the second housing component 8 has a first guide groove 17, which is shown in more detail below with reference to FIGS.
- the housing 1 can be assembled from the first housing component 7 and the second housing component 8 by pushing the two housing components 7 and 8 together in the guide direction via the guide groove 17 and the complementary element 16 which engages in the guide groove 17 .
- the direction of pushing together is the guiding direction and this is oriented parallel to the x-axis.
- the guiding direction is oriented in the -x-direction (negative x-direction).
- the interlocking of the first guide groove 17 and the first complementary element 16 causes a non-positive connection of the housing 1 in all directions perpendicular to the guide direction.
- the housing on the first side surface 3 openings, which in this case are openings with load circuit contacts 10 ', wherein the
- Load circuit contacts are passed through the openings.
- the load circuit contacts can be the load circuit contacts of a contactor.

- Load circuit contacts can here when assembling the housing components 7 and 8 simply through the openings in the first housing component 7, since the openings are oriented perpendicular to the direction of guidance, ie in the yz plane.
- the housing has a total of four attachment points, namely two first attachment points 9 and two second attachment points 9'. All attachment points 9 and 9' are arranged in areas that protrude from the cuboid housing and are preferably formed over a large area within the x-y plane.
- the attachment points 9 and 9' are suitable and intended for the housing to be attached to them via screw connections to an external element such as a support, as illustrated in more detail below.
- the first attachment points 9 are formed by inserting a metallic hollow sleeve 13 into aligned holes in the first housing component 7 and second housing component 8, which are part of an overlap region of the first housing component 7 and the second housing component 8, which is explained in more detail below.
- the hollow sleeves are oval in the current design, but can also be made circular.
- the second fastening points 9' can also have corresponding hollow sleeves.
- the first attachment points 9 with the hollow sleeves 13 serve as a safety device.
- the hollow sleeves 13 can be regarded as a safety component. The safeguard created in this way prevents the first housing component 7 and the second housing component 8 from being able to be displaced in relation to one another in the guide direction (that is to say parallel to the x-direction).
- the first guide groove 17, the first complementary element 16 and the fuse ensure a non-positive connection of the two housing components in all three spatial directions.

- the mating side 2 has an area of 25 to 100 cm ⁇ .
- a depth of the housing in the direction perpendicular to the plug-in side 2 can be 4 to 10 cm. In principle, however, the features described here can also be applied to housings that deviate from these dimensions.
- a plug 12 can have an area of 10 to 600 mm 2 .
- FIG. 2 shows the first exemplary embodiment of the housing 1 in a perspective view, with the housing components being shown spaced apart or separated from one another in the opposite guiding direction. This means that the first housing component 7 is shown displaced from the second housing component 8 in the x-direction. As a result, the guide groove 17 can be shown better in the overlapping area 142 . Unless otherwise indicated, all other components correspond to those shown in FIG.
- the housing 1 there is no electromechanical component in the housing 1 .
- the interior of the case is empty and no load circuit contacts are shown in the holes 10 .
- the housing 1 instead of a plug, the housing 1 has a free space 12' for a plug, into which a plug can be inserted. Alternatively, cabling could also be routed through the free space 12'.
- FIG. 2 clearly shows that the base side 14 of the housing 1 is formed from an overlapping part of the first housing component 7 and the second housing component 8 in the assembled state. These overlapping parts are respectively referred to as the overlap area 141 of the first housing component 7 and the overlap area 142 of the second housing component 8 .
- the entire side of the first housing component 7 that faces away from the viewer is the overlap area 141 of the first housing component 7.
- the overlapping area 142 is marked by the dashed line. In the assembled state, the overlapping area 141 and the overlapping area 142 overlap when viewed in the z-direction as a viewing direction.
- the first guide groove 17 is also formed in the overlapping area 142 and is provided and suitable for the first complementary element 16 to engage in it.
- first complementary element 16 can be pushed into the first guide groove 17 along the guide direction (here x-direction).

- the width of these components is defined perpendicular to the x-direction, ie parallel to the y-direction.
- the end of the guide groove 17 in the guide direction (-x- direction), starting from the nearest edge of the housing 1, can be understood as a depth stop up to which the housing components 7 and 8 are pushed into one another and, after being pushed together, remain in a firmly defined position relative to one another .
- the second housing component 8 has a plug-in area 15, which is a lowered area of the second housing component 8, onto which a corresponding area of the first housing component is plugged in order to achieve additional stability. Furthermore, the second housing component 8 has holes 9b which are aligned with holes 9a in the first housing component 7 in the assembled state. As shown in FIG. 1, a hollow sleeve 13 can then be inserted into this.

- the complementary element 16 and the guide groove 17 behave positively and negatively.
- the complementary element 16 shown here is more extensive in its width (y-direction) than in the guiding direction (-x-direction).
- a width of the complementary element 16 can correspond to between 20 and 80% of the width of the base side.
- a length can in principle be arbitrary. In the form shown, it corresponds to between 10 and 90% of the corresponding expansion of the base side in the same direction. In principle, the longer the guide groove 17 is, the more stable the connection can be, in particular with respect to torsion.
- the shape of the guide groove 17 and the associated complementary element 16 can be varied and is not particularly limited, as long as they allow the telescoping or nesting of the first and second
- Housing component as previously described, allows.

Due to the trapezoidal shape, it has undercuts.
- the complementary element 16 is formed on the overlapping area 141 of the first housing component 7 and engages in its undercuts with a shape that is complementary to the guide groove 17 and thus prevents the housing components from falling apart or being taken apart in all directions perpendicular to the guide direction, i.e. in all directions within the plane of representation of the cross section can become.
- the guide groove 17 and the complementary element 16 thus produce a non-positive connection in all directions perpendicular to the guide direction.
- the first complementary element 16 does not necessarily have to be formed completely or continuously over the entire length of the first guide groove 17 in the guide direction.
- the first complementary element 16 can have interruptions in the guiding direction.
- both the first complementary element 16 and the first guide groove 17 are designed to be continuous in the guide direction, which can make it easier to guide them evenly when the housing components are pushed together.
- the first guide groove 17 does not necessarily have to be continuous either. It could also be formed with an increased thickness in partial areas of the overlapping area 142 of the second housing component 8 and not in other, more flattened areas. However, a continuous first guide groove 17 is also to be preferred here for the aforementioned reasons.
- the first complementary element 16 does not necessarily have to reproduce the complete shape of the first guide groove 17, such as positive to negative, in order to be considered complementary in terms of its shape.
- the first complementary element 16 is designed as two wings, each of which engages in the trapezoidal undercut of the first guide groove 16 .
- FIG. 6 shows a further exemplary embodiment of a first guide groove 17 and a first complementary element 16, in which, unlike in the previous examples, there are no sloping undercuts here, but instead the first guide groove 17 and the first complementary element 16 have a T-shape and are therefore towards the base side 14 of the housing 1 has parallel undercuts.
- FIG. 7 shows an embodiment in which both a first guide groove 17 and a second guide groove 17' are provided.
- the first complementary element 16 and the second complementary element 16′ which are formed in a complementary manner, engage in these.
- These structures can, for example, be arranged symmetrically to a plane of symmetry of the housing. With these, a stability against twisting can be achieved, which would otherwise have to be achieved with a single, very wide, complementary element.
- their respective extent in the guide direction can preferably be greater than their width.
- Figure 8 shows a perspective view of a second embodiment of the present invention or of the housing 1. In this case, all the components as described for FIG. 1 are provided. In addition, the housing has a catch 19 in the plug-in side 2 .
- This latch 19 includes openings which are located in the first housing component 7 here. Hook-shaped elements of a latching element, which also includes resilient or flexible parts, engage in these openings. These are part of the second housing component 8 or are attached to it.
- the hook-shaped parts engage in the openings and allow an additional mechanically stable connection of the first housing component 7 and the second housing component 8.
- a gaping of the two housing components can be prevented in that the latch 19 forms a connection of the housing components which is opposite to the formed by the first guide groove 17 and the first complementary element 16 connection is arranged.
