In such devices, for example, a plurality of switch devices and individually provided optical displays generate a plurality of orders and / or display a plurality of states. Is effective.

[0003]

BACKGROUND OF THE INVENTION Known devices of the type described above include a plurality of openings in a plate forming a board, each of which passes through each of the openings. A hollow shaft fixed to the board and terminating at the outer flange outside the board is provided. The outer flange is provided with a push button or a dimmer cap (d
imer cap) is attached. The shaft further comprises, at the opposite inner end of the flange, means for removably connecting to a base intended to receive the electrical module. This electrical module is, for example, a switch module or an indicator lamp module depending on the surrounding environment. Such an electromechanical device is known from French Patent Publication No. 2,609,592. Further, as a module for the above-described electromechanical device, a module having a plurality of terminals or electrodes for electrical connection with a plurality of connection wires is known. These multiple electrical wires
Connect to pilot control or equipment monitor circuits, respectively, or establish interconnections between these multiple modules. The connection and / or interconnection wires mentioned above are generally sheathed flexible cables, the ends of which are respectively connected to the electrodes of these modules and the device to be controlled or monitored. .

[0004] However, compared to the strictly required time for mechanically installing multiple interacting units, such as multiple pushbuttons or optical indicators, on the plate, the connection or interconnection described above is not sufficient. It takes a considerable amount of time to do so. When the end of the wire is required to undergo processing such as tinning or positioning of a tubular socket for connection with multiple strands forming a core of flexible wire, Time further increases. In addition, these wires are provided with sheaths (sh
It is not possible to completely eliminate the risk of crossover of these wires, even when identification means are provided, e.g.

While it is quite possible to consider making connections and interconnecting a plurality of modules using printed circuit boards, whether access to the space between the plate and the printed circuit board is possible. That is a problem. In particular, in the event of a failure, the replacement of the printed circuit board and the module, or the simple replacement of only the failed module, requires that the printed circuit board be separable from all modules without soldering. You. Further, in use of the apparatus, the connection between the plate and the printed circuit board may be dangerous to the printed circuit board due to misalignment in the relative positioning on the plate and the printed circuit board. It can generate stress.

[0006] In order to partially solve the above problem, it has already been known to secure the printed circuit board using a plurality of small columns to create a space between the plate and the printed circuit board. Proposed. The strut is fixed to the plate with screws from outside the plate. The printed circuit board is pressed against the terminals of a plurality of modules by conductor strips. Thus, the printed circuit board can be easily removed. However, such an attachment would be unsightly, as the plate would be provided with a plurality of additional through holes, and the fixing screws would be visible on the front of the plate. In addition, the positioning of the printed circuit board depends on the mounting of the above-mentioned struts, which causes additional stress on the printed circuit board and the engagement between the terminals of the module and the corresponding conductor strips of the printed circuit board ( r
register) is rough and unstable.

Furthermore, the switches or display components provided in the above-mentioned known electromechanical devices need to be themselves compatible with the above-mentioned method. In particular,
There is a need to be able to pass through the small struts described above.

Link means for releasably securing and, on the one hand, a printed circuit board electrically connected to the plurality of modules and, on the other hand, electrically connected to the electrical device to be controlled and monitored. Wherein the plurality of modules are secured to the printed circuit board to form a rear subassembly, the front subassembly and the The sub-assemblies are mechanically and removably combined by the linking means, the linking means being accessible through a plurality of orifices in the printed circuit board before the combination is secured. And allowing play between the plurality of units and the plurality of modules in a plane substantially parallel to the printed circuit board.

[0012]

In the above manner, the plate and the printed circuit board can be connected without touching the connection between the module and the printed circuit board by simply separating the module from the interacting units. It is possible to access components (electrical modules and / or interaction units) located between them. Once this separation has taken place, for example, one or two modules on a printed circuit board can be replaced without having to remove the soldering of the other module,
Alternatively, the printed circuit board and all modules
A new rear subassembly can be replaced purely or simply. After this, it is only necessary again to be fixed with the front sub-assembly.

The play between the plurality of modules and the plurality of interacting units before the combination is fixed causes the interacting due to manufacturing errors of the plate and the printed circuit board. No stress is generated in the printed circuit board such that there is no complete engagement between the unit and the corresponding electrical module.

It is necessary to remove 1 solder.

Hereinafter, a method of the present invention which solves all of the above problems will be described.

As shown in FIG. 1, first, two subassemblies 105 and 106 are formed independently of each other. The subassembly 105 is quite mechanical and has a plate 2 on which the interaction units 3, 4, and 6 are mounted. Interaction units 3, 4, and 6
It has bases 23 and 27, a push button 54 (not shown in FIG. 1), a dimmer cap 81, and a reflector 83. At this stage, the electric modules 17, 1
8, and 19 are bases 23 and 27, respectively.
Not fixed.

In the following, the subassembly 105 will be referred to as the "front subassembly".

Simultaneously or in the front subassembly 10
Before or after manufacturing 5, a printed circuit board 8, electrical modules 17, 18, and 19, and a rear subassembly 106 with connectors 10 or flexible leads 9 are manufactured.

In order to connect each module 17, 18, and 19 to the printed circuit, each module 17, 1
8 and 19 have two electrodes 21, a centering stud 31 and a plurality of projections 34. Two electrodes 21
Has a corresponding hole 39 in the printed circuit board 8 (FIG. 3) on its side facing the printed circuit board 8 to connect each module 17, 18, and 19 to the printed circuit board 8.
Made in the form of a spike on a cylinder prepared inside. The centering stud 31 has an axis XX ′ perpendicular to the printed circuit board 8.
Has a bevel 32 and a lateral slot 31a so that it can be elastically compressed in the radial direction. Multiple protrusions 3
4 is for supporting the printed circuit board 8.

To mount a module such as module 17 on printed circuit board 8, terminals 21 are pressed into openings 39 and centering studs 31 are simultaneously printed until protrusions 34 hit printed circuit board 8. It is pushed into the corresponding opening 35 of the circuit board 8.
The length q of the terminal 21 and the stud 31 is relative to the thickness e of the printed circuit board 8 and the height d of the projection 34 when the projection 34 contacts the inner surface 8 b of the printed circuit board 8. And a length such that the stud 31 protrudes from the rear surface 8a of the printed circuit board 8. A plurality of printed circuits are formed on the front surface 8a of the printed circuit board 8. Then, the terminal 21 contacts the conductor strip 37 belonging to the above-mentioned printed circuit on the surface 8a. The studs 31, when given their radial elastic modulus, perform positioning between the plurality of modules and the printed circuit board without play or excessive force. Thus, each module 17, 1
8, or 19, are precisely positioned in the XX 'direction as a result of the contacting pressure of the projections 34, each module 1
7, 18, or 19 have good longitudinal stability and good angular orientation due to the multiple mechanical contacts between each module and the printed circuit board. In particular, terminal 21
Fixes the angular direction of each module 17 around the axis XX '

The interconnection between the modules 17, 18, 19 and the printed circuit board 8 provide terminals 21 in the area 37,
In particular, so-called wave soldering (wave solder)
ing method, in other words, by soldering using a soft solder bath. In addition to the function of electrical contact, the soldering operation holds the modules 17, 18, 19 in position relative to the printed circuit board 8 along the axis XX '.

The rear subassembly 106 before assembly is shown on the left side of FIG. The rear subassembly 106 after assembly is shown on the right side of FIG.

Then, the two sub-assemblies 105 and 106 comprise modules 17, 18, and 19
The modules 17, 18, and 19 are coupled to each other by being fixed to bases 23 and 27 provided for receiving the modules.

For this fixation, as shown in FIGS. 4 and 7, the modules 17, 18, and 19
A larger orifice 4 traversed by a plurality of channels 43 extending parallel to X 'and passing through the rear face 30 of the plurality of modules and formed through a printed circuit.
8 has an opening 42 disposed opposite to the opening 8. At the other end, each channel 43 opens out to a threaded bore 66 in the base 23 or 27. In the case of the base 23, it is made essentially of plastic, the bore 66 being in a metal insert 67 crimped on the plastic of this base.

Small size modules 17 and 18
Has only one channel 43 and is fixed by one screw 44. The large size module 19
It has two channels 43 with two screws 44.

Two subassemblies 105 and 106
Are introduced into the channels 43 through the corresponding orifices 48 of the printed circuit board 8. The screw 44 directs its head 45 close to the printed circuit board 8 and the threaded end portion 46 of the screw 44 is threaded into a threaded bore 66 in the base 23 or 27.

As shown in FIGS. 4 and 7, the screw 44
Has a certain clearance in the radial direction relative to the axis XX ′. FIGS. 5 and 8 show that the plurality of channels 43 are
It has a shape extending around the axis XX '. As a result, relative to the module 23, ± A (± 5 in the example not shown) around the axis XX ′ relative to the base 23.
°) gives a positioning error in each direction, equal to:

As a result of these radial and circumferential clearances of each screw 44 in the channel 43,
Before the screw 43 is tightened, the printed circuit board 8
And in the plane parallel to the plate 2 there is play between each module and the interaction unit. This play allows the electrical module 17, 18 or 1
9 and the relative position of the interaction unit 3 or 6 to be connected to the module, as shown in FIGS. It is possible to insert the section 46 into a corresponding threaded bore 66 in the base. In such a case, the plurality of channels 43 are offset from the center, but no stress is generated particularly in the printed circuit board.

To tighten the screw 45, the screwdriver 87 is screwed through the orifice 48 of the printed circuit board 8
4 head 45 can be reached.

A plurality of screws 45 extend between the printed circuit board 8 and the front subassembly 105 over the entire depth of the modules 17-19 when measured perpendicular to the printed circuit board 8, and It is easy to tighten the screw 44 with the screwdriver 87 because the head is immediately adjacent to the printed circuit board orifice 48 and directly accessible.

When connecting the subassemblies 105 and 106, a plurality of lugs as indicated by reference numeral 68 in FIGS. , 18,
Alternatively, an approximation can be made between 19 and the corresponding interaction unit. Then, the lugs can engage in the corresponding grooves 72 of the base.

The plurality of grooves 72 are present in the form of an arc around the axis YY 'of the interaction unit. And the plurality of lugs 68 also have a corresponding shape, but have a smaller size to have play in the plurality of grooves 72 corresponding to what is allowed for the screw 44 in the plurality of channels 43. doing.

As shown in more detail in FIG. 5 in cross section BB, a plurality of lugs 68 are chamfered 68a around their free ends to assist in mating with grooves 72.

To prevent mounting errors during the manufacture of the rear subassembly 106, the plurality of through holes 39 for the plurality of terminals 21 and the plurality of orifices 48 allowing the introduction of the plurality of screws 44, Multiple centering openings 3
The placement of 5 depends on the type of module that is functionally adapted to the location of interest on the printed circuit board. By way of example, FIG. 9 shows the relative arrangement of switch modules (eg, module 17) that are open when stationary. FIG.
Indicates an arrangement of the switch module (for example, the module 18) which is closed when the vehicle is at rest. FIG. 11 shows an arrangement of a display module (for example, module 19) for optical display.
And FIG. 12 shows an arrangement of a module 120 (not shown in detail) that couples the two switches and the optical display.

[0051] Other types of modules are also conceivable, such as, for example, a module having two or more switches.

In the embodiment shown in FIGS. 1 and 2 and described above, the assembly of each module / interaction unit takes place between the plate 2 and the printed circuit board 8 in a direction perpendicular to the printed circuit board 8. If one has the same space requirements between the plate 2 and the printed circuit board 8 as the space requirements, the two subassemblies, one 105 mechanical and the other 106 electrical, connect Is done. On the other hand, a working module 17 '(FIG. 1)
3) has a larger size than the other working modules 19 '.

In this case, a working module 17 ′ with a large depth on the one hand and a working module 19 ′ on the other hand an electrical extension 108 inserted in series between the module 19 ′ and the printed circuit board 8. Along with
Used as the electrical module of the present invention. The electrical extension 108 includes a plurality of terminals 21 and centering studs 31.
Hold. The electrical extension 108 also has a plurality of channels (not shown) that engage the plurality of channels 43 of the working module 19 ', which is the same as the module 19 of FIG. It is connected to a plurality of clips 110 that grip a plurality of terminals 21 ′ of a plurality of working modules 19 ′ of the electrical extension 108. The recess 35 'of the electrical extension 108 receives the centering stud 31' of the working module 19 '. The screws used to assemble the two front and rear subassemblies are:
4 and 7 respectively, but with electrical extension 108 and working module 1
It is longer to traverse both 9 'or to traverse the entire depth of working module 17'.

Once the device has been manufactured, the module 1
7 to 19 can hold the printed circuit board 8 without generating any stress. In addition, when disassembly is required, only the reverse of the manufacturing procedure need be performed. In other words, first, by loosening the plurality of screws 44, the two subassemblies 10
5 and 106 are separated. Then, complete replacement of the entire rear subassembly 106 or selective replacement of one or more modules on the printed circuit board may be performed as desired.

The present invention is, of course, not limited to the above embodiment.

In particular, by way of example, by means of bases 23 or 27, respectively, and by means of one nut 13 or screw 84
Two different embodiments are shown in FIGS. 3 and 6, respectively, by fixation using.

For modules having different sizes perpendicular to the plane of the printed circuit board, it is also possible to use complementary sized interaction units, for example, using a base of suitable depth. . Intermediate components forming shims between the bases and the modules having a relatively reduced depth may also be selectively secured on the same base.

In other words, the product manufactured by this method can be quickly and rationally disassembled in the event of a failure.

The pre-wired electromechanical device for control and / or display of the present invention is also amenable to the implementation of the method described above, which can be quickly and rationally disassembled in the event of a failure, and can be used with plates and plates. Whether the manufacturing error of the printed circuit board removes the stress on the printed circuit board,
Alternatively, there is the effect of being at least greatly reduced.
