Definitions
- the invention relates to methods for assembling a circuit module in which a circuit carrier is introduced into a basic housing body and the basic housing body is closed with the aid of cover elements.
- the invention further relates to a pressure bar and a circuit module with an electronic component.
- housings are therefore developed to accommodate printed circuit boards, which are adapted in size and structure to the printed circuit boards used in each case.
- the known housings have very little mechanical similarity to one another.
- Each type of housing also requires its own new tool kit for the production of base plates, lids, plugs and other fastening parts.
- housings that are inexpensive to produce and easy to assemble and that are suitable for accommodating control electronics that are arranged outside the transmission.
- These housings can either be leakproof or leakproof.
- the device structure and the assembly process should be carried out with as few components as possible, as well as work and process steps.
- the invention is therefore based on the object of providing a simple and inexpensive to create a method for assembling a circuit module.
- the invention is also based on the object of providing suitable semi-finished products for carrying out the method.
- the housing base body is preferably produced by dividing a hollow profile and the openings on the transverse sides of the housing base body are closed with the cover elements.
- the length of the basic housing body can be varied almost as desired. It is therefore possible, starting from a hollow profile, to produce housing bodies of different lengths that can be fitted with circuit carriers of different lengths.
- the length of the basic housing body can in particular be chosen so that no empty volumes arise within the housing.
- the hollow profile is preferably extruded.
- the cross-sectional profile can be designed in a simple manner in such a way that a circuit carrier can be fastened in the housing without further fastening means.
- contact surfaces for the circuit carrier can be provided, which are arranged in such a way that a circuit carrier equipped on both sides can also be inserted into the basic housing body.
- the circuit carrier is preferably introduced into the basic housing body in such a way that the flat sides of the circuit carrier face the walls of the basic housing body.
- an elongated pressure strip is introduced, which lies against the main body of the housing and the circuit carrier. Due to the pressing force generated by the pressure bar, the circuit carrier is pressed against the basic housing body and is thus held in the basic housing body.
- This solution offers the advantage that the pressure bar can be introduced in a simple manner through the opening through which the circuit carrier has also been introduced into the basic housing body. Therefore, no additional openings in the basic housing body are required in order to fasten the circuit carrier in the basic housing body. Since a pressure bar is used to hold down the circuit carrier, there is no risk that the holder will come loose under vibration.
- the bracket with the help of the pressure bar inserted between the basic body and the circuit board is therefore easy to install and ensures a secure fixation of the circuit board.
- the pressure bar is serpentine.
- the coil spring contracts, a force transmission takes place, by means of which the holding force acting on the circuit carrier can be increased.
- Pressure bar a serpentine tension spring, which contracts in the space between the circuit carrier and a wall of the housing base.
- a pressure bar is particularly well protected against jamming, since clamping points are loosened by the tensile force of the spring.
- the pressure strip has spring rings arranged one behind the other, which are deformed during assembly of the circuit carrier in such a way that they impart a spring force between the walls of the housing base body and the circuit carrier.
- a cover element is provided with a sword in a further embodiment, which extends into the interior of the basic housing body when this covering element is attached to the transverse side of the basic housing body.
- Guide grooves can be provided for guiding the sword inside the basic housing body, which are preferably encapsulated to prevent electronic components from shearing off on the printed circuit board when the sword is inserted.
- spring elements are formed along the swords, which press the circuit board onto a support surface.
- these spring elements are made of a good heat-conducting material, in particular a metal, e.g. a copper-beryllium alloy, so that heat can be dissipated from the circuit board to the base body via the spring elements.
- the cover elements which close opposite openings are designed to be complementary in that one of the cover elements is provided with a sword which engages in a form-fitting manner in a recess in the opposite cover element. This can be done with the help of a latching, hooking or interlocking.
- a cover element is provided with a contact means, for example a socket or a plug.
- the contact means is preferably attached to the circuit board before the circuit board is inserted into the basic housing body.
- the circuit board guides the cover element when it is inserted into the basic housing body, so that it is held in position, for example, during a screwing-in process.
- the printed circuit board fastened to the covering element via the contact means is held securely in the basic housing body.
- cooling fins extending along the longitudinal axis can be formed on the outside of the basic housing body. Furthermore, it may make sense to provide cooling fins on the cover elements through which the waste heat can be released to the ambient air.

- Figures 21A and 21B illustrate the compression of a
- Figure 1 shows a circuit board 1, which is equipped with electronic components 2.
- the circuit board 1 together with the components 2 is referred to below as electronic component 3.
- Soldering eyes 4 for contact pins 5 of a plug 7 formed on a cover element 6 are provided in the printed circuit board 1.
- the cover element 6 provided with the plug 7 is also referred to below as a front cover element 6.
- the circuit board 1 also has locking holes 8 into which locking knobs 9 formed on the cover element 6 can snap.
- a hollow body 10 which corresponds to the length of the circuit board 1 from a cavity profile was divided.
- the hollow profile is thus the semifinished product from which the hollow body 10 is produced by a simple separation process.
- the cross-sectional profile of the hollow body 10 is designed such that the cover element 6 can be attached to a front transverse side 11 in order to close off a front opening 12.
- recesses 13 are provided along the longitudinal edges of the hollow body 10, into which, for example, self-tapping screws can be screwed.
- the recesses 13 extend along the longitudinal edges of the hollow body 10 and the front transverse side 11 to a rear transverse side 14, so that a rear opening 15 can also be covered on the rear transverse side 14 with the aid of a suitable cover element.
- the cross-sectional profile is also designed such that there are support surfaces 16 on which the inserted circuit board 1 rests.
- the bearing surfaces 16 are arranged such that a printed circuit board 1 equipped on both sides can also be inserted into the hollow body 10.
- the height of the hollow body 10 is selected so that the components 2 that are usually used on the printed circuit board 1 find sufficient space in the hollow body 10.
- a large-area contact between the hollow body 10 and the printed circuit board 1 inserted into the hollow body 10 is produced by the contact surfaces 16.
- the loss of heat generated by the components 2 on the printed circuit board 1 can be transferred from the printed circuit board 1 to the hollow body 10 via these large-area contact points and released from there to the ambient air.
- Encapsulated guide grooves 17 are also provided in the hollow body 10, the function of which will be explained in more detail below.
- the guide grooves 17 are each formed by an inner guide web 18 and a lateral outer wall 19.
- the up Contact surfaces 16, on the other hand, are part of the lower outer wall 20 of the hollow body 10.
- the upper outer wall 21 has no particular course and runs in a straight line between the recesses 13 arranged along the longitudinal edges.
- FIG. 3 shows a perspective view of how the circuit board 1 is inserted into the hollow body 10.
- the circuit board 1 is placed on the support surfaces 16 and then inserted under the guide web 18 into the hollow body 10.
- the circuit board 1 is guided by the support surface 16 and the lateral outer walls 19. This type of guidance also ensures that screw holes 22 of the cover element 6 come to rest on the recesses 13 of the hollow body 10.
- the cover element 6 can then be fastened to the hollow body 10 with the aid of self-tapping screws 23.
- a sealing ring 24 can also be introduced between the hollow body 10 and the cover element 6. In its cross-sectional profile, the sealing ring 24 follows the cross-sectional profile of the hollow body 10, so that the cover element 6 seals the hollow body 10 tightly after the circuit board 1 has been inserted into the hollow body 10.
- FIG. 4 shows a perspective view of the assembly of a rear cover element 25.
- the rear cover element 25 is equipped with swords 26, on which spring washers 27 are formed.
- the outer diameter of the spring washers 27 is somewhat larger than the height of the guide grooves 17 minus the thickness of the printed circuit board 1.
- the swords 26 must therefore be pushed into the guide grooves 17 with force.
- the screws 23 absorb the thrust forces acting on the printed circuit board 1.
- the spring rings 27 are replaced by further spring elements. So they can
- Swords 26 can be wave-shaped or leaf springs have which act in the transverse direction.
- the swords 26 can be made of metal as well as plastic.
- the spring washers or spring elements are made of a good heat-conducting material, in particular a metal, e.g. a copper-beryllium alloy.
- a metal e.g. a copper-beryllium alloy.
- the inner guide webs 18 are provided so that the swords 26 do not dodge when inserted and the components 2 arranged on the printed circuit board 1 shear off.
- the printed circuit board 1 is pressed firmly against the bearing surfaces 16 by the spring washers 27. In this way, the heat transfer between the circuit board 1 and the hollow body 10 is ensured. Furthermore, the printed circuit board 1 is secured against vibration loads.
- the printed circuit board 1 can be a heat-conducting paste or heat-conducting film, by means of which the printed circuit board 1 is insulated from the hollow body 10.
- the circuit board 1 can also be isolated from the hollow body 10 by anodizing the hollow body 10. In these cases, the printed circuit board can first be introduced into the hollow body 10 in contact with the guide webs 18 and then placed in the last phase of insertion on the supporting surfaces 16 and pressed with the swords 26 of the rear cover element 25 so that the heat-conducting paste, electrical insulation produced in the heat-conducting film or the oxide layer is retained.
- the rear cover element 25 After the rear cover element 25 has been inserted, the rear cover element 25 is fastened to the hollow body 10 with the aid of self-tapping screws 28.
- the leadership the swords 26 in the guide grooves 17 ensure that screw holes 29 of the rear cover element 25 fit snugly on the recesses 13 of the hollow body 10.
- the rear cover element 25 and the swords 26 are preferably produced in one piece as injection molded parts.
- the cover elements 25 and the swords 26 are separate parts that are assembled separately.
- spring slats which are supplied as bulk goods and on which the spring rings 27 are formed, can be inserted into the hollow body 10.
- a sealing ring 30 can also be introduced between the rear cover element 25 and the hollow body 10.
- Sealing ring 30 causes the rear opening 15 to be sealed by the rear cover element 25.
- the sealing ring 30 has the same shape as the sealing ring 24. It is therefore possible to seal the two openings 12 and 15 with a type of sealing ring.
- FIG. 5 shows a perspective view of a fully assembled circuit module 31.
- FIG. 6 also shows a perspective view from behind of the fully assembled circuit module 31.
- FIG. 7 shows a cross section through the circuit module 31. It can be clearly seen that the spring washers 27 are compressed in the guide groove 17 and thus exert a spring force on the printed circuit board 1, by means of which the printed circuit board 1 is pressed onto the contact surface 16.
- FIG. 8 shows a cross section through a modified exemplary embodiment of the circuit module 31.
- the swords 26 are provided with a sawtooth profile 32, which is in the region of the front Cover element 6 engages positively in the teeth of a recess 33.
- the rear cover element 25 and the front cover element 6 are locked against one another.
- the hollow body 10 is clamped between the front cover element 6 and the rear cover element 25.
- the screws 23 and 28 can therefore basically be dispensed with. In this way, a stiff and tight circuit module 31 can be produced with very few steps and without screwing and gluing processes.
- the sawtooth profile 32, the length of the swords 26 and the latching of the recesses 33 should be dimensioned such that the swords 26 extend into the recesses 33 with a sufficient insertion length. So that the length of the swords 26 can be adapted to the length of the printed circuit boards 1, predetermined breaking points 34 are provided along the swords 26, by means of which the length of the swords 26 is shortened and thus can be adapted to the length of the respective hollow body 10 and the respective printed circuit board 1 , By cutting to length at the predetermined breaking points 34, the swords 26 can therefore be adapted to the present length of the printed circuit board 1.
- the hollow body 10 is provided on the outside with cooling fins, with which the heat transfer from the hollow body 10 to the ambient air can be improved.
- the hollow body 10 of the circuit module 31 shown in FIGS. 5 and 6 is preferably made of a metallic material.
- the embodiment shown in FIG. 9 has a hollow body 35 which is made of plastic.
- guide grooves 36 are provided which surround the printed circuit board 1 when it is inserted. Since the heat generated by the circuit board 1 is not dissipated via the hollow body 35 made of plastic no special contact surface is provided, through which a large-area contact between the circuit board 1 and the hollow body 35 is produced. Rather, the function of the guide grooves 36 is limited to securely fixing the circuit board 1 in the interior of the hollow body 35.
- FIG. 10 shows a metallic cover element 37 on the back, which is provided on its outside with cooling fins 38. On its inside, the rear cover element 37 has a contact strip 39 and two laterally arranged clamping lugs 40. As shown in FIG. 11, the rear cover element 37 is applied to the rear opening 15 of the hollow body 35 and screwed there with the aid of the screws 28.
- FIG. 12 shows a cross-sectional view of the printed circuit board 1 and the rear cover element 37 at a point in time when the rear cover element 37 has not yet been completely pushed onto the printed circuit board 1.
- FIG. 13 on the other hand, the rear cover element 37 has already been pushed completely onto the circuit board 1.
- the contact strip 39 lies over a large area on the underside of the printed circuit board 1 and brings about the heat transfer between the printed circuit board 1 and the rear cover element 37.
- the wedge-shaped clamping lugs 40 ensure the necessary contact pressure.
- the hollow bodies 10 and 35 can be adapted to the different types of printed circuit boards 1. The adjustment can be made without changing the tool, since only the cutting process has to be modified. Overall, only one set of tools for the extrusion of the hollow body 10 or of the hollow body 35 needs to be produced. The length of the hollow bodies 10 and 35 can always be chosen such that none inside the finished circuit module White spaces are created. Another advantage is the low assembly effort, which is due to the small number of parts. Assembly is also facilitated by the fact that essentially only joining processes have to be carried out. Despite the simple assembly, rigid, mechanically strong and hermetically sealed housings can be manufactured.
- Another advantage is that the waste heat generated on the circuit board 1 can be safely dissipated with the aid of the housing.
- there is a high level of vibration resistance since the printed circuit board 1 is gripped over a large area in the hollow bodies 10 and 35 from at least three sides.
- FIG. 14 shows an exploded view of a further circuit module 41, which houses the circuit of a transmission control or a motor control, for example on a circuit board 42.
- the circuit board 42 can be introduced into the housing base body 44 through a front opening 43 of a housing base body 44.
- the circuit board 42 lies on shoulders 45 of a housing base during insertion.
- the housing base body 44 can be, for example, the separated part of an extruded profile which is made of aluminum or plastic.
- the circuit board 42 has already been attached to a front cover 47, which has a socket 48 on the outside, with which the circuit board 42 can be electrically contacted, before it is introduced into the basic housing body 44.
- Spring strips 49 are also fastened to the cover 47 and are introduced into encapsulated guide grooves 50 of the housing base body 44 when the circuit board 42 is inserted into the housing base body 44.
- the introduction of the female connectors 49 will be described in detail below.
- FIGS. 15A to 15C The introduction of the female connector 49 is shown in detail in FIGS. 15A to 15C.
- the female connector 49 and the associated guide groove 50 have been drawn too high compared to the illustration in FIG. In principle, however, it is also conceivable to actually modify the housing base body 44 shown in FIG. 14 and the female connectors 49 in such a way that the female connectors 49 differ from the
- PCB 42 extend to a ceiling wall 53 of the housing base body 44.
- the printed circuit board 42 has already been pushed into the basic housing body 44.
- the female connector 49 is still in the relaxed state in front of the front opening 43 of the housing base body 44.
- the printed circuit board 42 has already been inserted further into the basic housing body 44.
- a front end 54 of the female connector 49 has been picked up with a tool, not shown, and the female connector 49 has been pulled apart.
- the tool used for tensioning the female connector 49 has been inserted into the housing base body 44 through the rear opening 51.
- a tool inserted through the rear opening 51 is not absolutely necessary for pulling on the female connector 49. It is also conceivable to attach the end 54 of the female connector 49 to the printed circuit board 42 before it is inserted. After inserting the circuit board 42, the end 54 of the female connector 49 can then be detached from the circuit board 42.
- the female connector 49 is released, as shown in FIG. 15C. sen.
- the female connector then contracts until it rests against both the printed circuit board 42 and the top wall 53 of the basic housing body 44.
- the low height of the housing base body 44 or the guide groove 50 does not allow the spring bar 49 to be completely relaxed.
- Axial Relaxing forces F z the result of the spring segment 55 engage board-side apexes 56 (h + .DELTA.h) to a contraction (a-.DELTA.a) and at a higher are of the spring segment 55.
- the contact pressure F k is increased compared to the relaxation force F z .
- a compression spring instead of the spring strip 49 designed as a tension spring.
- a pressing force 57 is applied from the outside.
- the female connector 49 is compressed by the pressing force 57.
- Due to non-uniform friction coefficients at clamping locations 58, a certain spring flank 59 of the serpentine spring strip 49 can be set up steeper than other spring flanks. In this case, almost the entire pressing force 57 is absorbed at the clamping locations 58 in front of the spring flank 59. In particular, the pressing force 57 is not transmitted to the further spring segments located downstream.
- the spring segments lying downstream will want to continue to contract and pull the spring flank 59 of the spring segment 55 potentially jamming due to this increased friction and thus reduce the steepness of the spring flanks 59.
- the contact pressure acting on the printed circuit board 42 and the top wall 53 is reduced.
- the reduction in the contact pressure then reduces the frictional force between the female connector 49 and the printed circuit board 42 and the housing base body 44.
- the relaxation force acting in the spring segments 55 apart from the jammed spring segment 55 therefore attracts the jammed spring segment 55, as a result of which the entire female connector 49 is shortened evenly as a result.
- This compensation effect takes place at each contact point between the female connector 49 and the printed circuit board 42 and the housing base body 44 and ensures a uniform force distribution of the contact pressure acting on the printed circuit board 42.
- a spring bar 49 designed as a tension spring is that the pressing force 57 does not have to be constantly applied from the outside in order to hold down the printed circuit board 42.
- the axial spring force required to hold down the circuit board 42 is itself generated and maintained independently by a spring strip 49 designed as a tension spring, without having to act on the spring strip 49 from the outside.
- the latter means that installation is considerably easier since, in the case of a spring strip 49 designed as a tension spring, the cover 52 can simply be screwed onto the rear opening 51 without the spring strip 49 having to be compressed.
- FIG. 18 shows a cross section through the circuit module 41 in the fully assembled state, the spring strip 49 being a tension spring or a compression spring. Irrespective of this, the the covers 47 and 52 are fastened to the housing base body with screws 60. If the spring bar 49 is a compression spring, the pressing force required to compress the compression spring is applied by the covers 47 and 52.
- FIG. 19 shows a further embodiment of the circuit module 41, in which the female connector 49 has individual flexible tongues 61.
- This embodiment is particularly advantageous if the female connector 49 is to be locked in the circuit board 42, for example. It is also advantageous if the flat side of the female connector 49 facing away from the flexible tongues 61 rests on the printed circuit board 42, since this is then loaded evenly. In addition, such female connectors 49 can be manufactured particularly easily.
- FIG. 20 shows a further exemplary embodiment in which the spring strip 49 has spring washers 62.
- the female connector 49 shown in the exemplary embodiment in FIG. 20 can also be thought of as being composed of two serpentine female connectors.
- the female connector 49 of the exemplary embodiment shown in FIG. 20 can likewise be designed as a tension or compression spring like the female connector 49 shown in FIGS. 14 to 18.
- FIGS. 21A and 21B show the function of the female connector 49 from FIG. 20.
- the advantage of these embodiments is that the female connectors 49 of the exemplary embodiments shown in FIGS. 19 and 20 can be overpressed more easily than the serpentine female connectors 49 of the exemplary embodiments shown in FIGS. 14 to 18. In the exemplary embodiments illustrated in FIGS. 19 and 20, there is therefore less to fear that the female connector 49 jams when inserted, as is the case with the serpentine female connector 49.
- female connectors can be used.
- a female connector with a single spring segment 55 can also be used to hold down the printed circuit board 42.
- Another conceivable embodiment comprises a female connector, in which a plurality of spring rings 62 arranged one above the other provide the pressing force required to hold down the printed circuit board 42.
- a female connector can be thought of as a stack of serpentine female connectors arranged one above the other, which together form a resilient braid.
- FIGS. 19 to 21 have in common that the printed circuit board 42 is introduced into the basic housing body 44 in such a way that a flat side 63 faces the housing base 46 and a flat side 64 faces the ceiling wall 53.
- This offers the advantage that the female connector 49 can be inserted into the basic housing body 44 together with the printed circuit board 42.
- the spring strip 49 can also be attached to one of the covers 47 and 52.
- the printed circuit board 42 is essentially fixed by the spring force of the female connector 49 and by the covers 47 and 52.
- knobs or pins can be provided, for example, in the region of the guide grooves, by means of which the printed circuit board is fixed in the insertion direction.
- transverse strips are attached to the printed circuit boards in the manner of a component, to which spring strips extending in the longitudinal direction are attached.
- the female connectors do not need to be attached to the covers used to close the basic housing body.
- the circuit module does not necessarily have to accommodate a circuit board. It is also conceivable to introduce a single component, for example a relay or a transformer, into the basic housing body. In this case, the encapsulated guide grooves can be dispensed with, since there is no risk that the component will be damaged by the female connectors during insertion.
