Description

Assembly with multiple-wired components.

The invention relates to an assembly with coordinates Structure of a plurality of components' with at least groups per component designed and arranged identically, over the soldering lugs of comb-like multiple strips electrically connected in parallel Anechluaaelementen, in particular relay coupling field plate for telephone systems.

Purely for the wiring of assemblies of the aforementioned type, it is already known to use so-called circuit boards with written or printed circuitry instead of time-consuming individual wiring which is also subject to the risk of a large error rate. In this method, the components are mounted on a carrier plate made of insulating material, which is provided with loops for the passage of the connecting elements of the components or lines to be connected and is wired as series parts before the components are assembled the wiring in the case of the written circuit using bare wire is optionally made by machine according to a given circuit diagram and in the case of the printed circuit is generated by etching a photo-chemically treated so-called laminated, i.e. coated carrier plate with a copper foil or a copper layer . Of these methods, the first mentioned has the disadvantage that

VPA 9 / 61o / o245 Pfa / S ti

if the work is carried out manually, a recurring one exact observance of the circuit diagram as well as careful soldering requires and, in the case of machine handling, of practically inevitable signs of fatigue and slacking off care is largely free, however, dine not always simple programming, setting and constant monitoring of the machine required, so all in all one does not is subject to insignificant possibility of error or at least is expensive in the manufacturing process. Opposite are with the circuit boards mentioned in second place printed (etched) circuit as a result of the one-time created and re-controllable before regular use photographic template switching errors largely excluded, but this manufacturing process is first because of the relatively slow progressive etching Time-consuming and secondly because of the multi-stage work cycles including the necessary thorough rinsing expensive and less suitable for large-scale production.

In contrast, discloses the present invention Massnahinen for creating an assembly of the type mentioned that the can be produced automated while substantially avoiding the disadvantages of the known arrangements and methods, that is especially rapidly and ratiOEll, as error free and ausaer- w.

This is achieved according to the invention in that the An assembly is preferably manufactured by injection molding Carrier plate also has insulating material on its two surfaces that run parallel to the plane of the plate at least two groups of mutually parallel grooves and at least openings that cross each other at right angles for the passage of the connection elements of the components and partly at the same time for the soldering lugs of the multiple strips having and preferably punched from non-ferrous metal sheet is equipped with solderable multiple strips, the base webs of which

VPA 9 / 6I0 / 0245 209825/028 4

are inserted into the grooves and their corresponding to the pitch - The assembly in periodically recurring spacing arranged soldering lugs in the direction of insertion of the connection elements of the components protrude, and that the multiple strips and the openings of the carrier plate or the grooves are designed such that the connection elements of the components mounted on the assembly and the associated soldering lugs the multifunctional strip under mechanical pretension touch.

In this training of the assembly can be except one Carrier plate which is simple and can also be produced repeatedly and precisely using the injection molding process Use multiple strips, first as series components are extremely cheap to manufacture and, secondly, as a result of their error-free arrangement of the soldering lugs given by the punching tool for careful manual assembly independent electrical connection of the connection elements to be switched in parallel is guaranteed. There are also others Advantages that on the one hand the multiple strips, connecting strips and given] traps existing bridges in the hit simple formation of these parts and the carrier plate with their grooves quickly and easily in their desired position can be brought and on the other hand the assembled components without any additional fasteners or measures via their penetrating the openings of the carrier plate and resting on them under prestress Solder lugs of the multiple strips before dip soldering, that is, in practice, for example during the assembly time of the carrier plate can be held self-locking until dip soldering. It is also a remarkable one The advantage that the connection elements of the components and the soldering lugs to be contacted with them of the multiple strips automatically touch when assembling the components without additional effort in terms of working time and equipment

and in this way, firstly, it is possible to cover the entire connection points to be soldered in a single time-saving immersion process and, on the other hand, by the intimate touch also for a reliable soldered connection is ensured. A very special advantage, especially compared to the one cited in the introduction well-known method of etching a printed circuit is the rapid follow-up option in series production of assemblies according to the present invention, because neither a chemical pre- nor post-treatment in the wet process, but only one dry processing with one only through the cycle sequence when inserting the multiple strips and the * Subsequent dip soldering, limited processing required is.

If, according to a further development of the invention, the openings in the carrier plate in each case on the insertion side of the connection elements or the soldering lugs, at least partially in the shape of a funnel are formed, this facilitates the introduction of both the connection elements of the components and the soldering lugs the multiple strips and any connection strips and bridges that may be present, which in particular for an automated one Equipping the carrier plate is advantageous.

connecting strip are electrically connected. In this way can despite the coordinate structure of the multiple strips all electrical connections can be connected to a single collective connection strip, which is essential for further Wiring of the module, for example via a

. Terrfer is ^v

Control wiring is useful / it is beneficial for that too this additional wiring of the multiple strips with the The collective connection bar essentially uses the same components and methods as for multiple connections within the Assembly are usable. ■.

If, in the case of the above-mentioned exemplary embodiment of the subject matter of the invention, according to another Development of the invention: the opening in the funnel plate for the short leg of the connecting strip to pass through has an inclined surface which, at the insertion end of the opening, merges into a funnel that widens outwards and at the opposite end the clear width of the opening reduces, on the one hand, the threading of the short leg of the connecting strip into the opening is facilitated in this way and on the other hand this leg in its desired position opposite the soldering lug to be contacted with it brought the multiple strips in question, with a certain self-locking bracket is also achieved at the same time.

In order to achieve an intimate connection between the connection elements of the components and the soldering lugs of the multiple strips, which is important for the subsequent dip soldering, according to one embodiment of the invention the openings for the passage of the connection elements of the components can be simple cylindrical holes with _> an inside diameter greater than the largest dimension of the cross section of a connection element, on the other hand the openings for the simultaneous passage of the soldering lugs of the multiple strips

'209 8 25/0284

as essentially cuboid channels, each with one a soldering lug of a multiple soldering hoop pushed into the channel formed laterally to the longitudinal axis of the channel deflecting inclined surface and the soldering lugs of the mounting side of the Components arranged opposite multiple strips in the direction of the aforementioned cylindrical openings to in each case be angled over its adjacent edge. Here you can the all cuboid channels formed openings have a channel which is arranged opposite their inclined surface and is positively adapted to half the cross-section of a connection element, whereby a defined positioning of the connection elements is ensured.

According to another embodiment of the invention, the the necessary intimate connection between the elements that are later to be soldered together can also be achieved by that the insertion level of the grooves by a certain, to the plane of the carrier plate, depending on the position of the respective associated openings, angular amount inclined to one side or the other is inclined. This inclined position of the insertion plane of the grooves is in fact very simple in itself and also in the course of the spraying process for the carrier plate also cheap way ensured that the connecting elements and the soldering lugs cross, the size of the angle of inclination of the insertion plane being the mechanical preload determined when touching the parts. The elements to be soldered to one another are only in contact with one another, however punctually, whereas in the first-mentioned method by means of of the inclined surfaces in the cuboid openings of the carrier plate the soldering lugs are deformed during the assembly of the components in such a way that they are attached to the connection elements via a larger one Fit across the area.

A further development of the invention provides that in the carrier plate others, in groups with their base in each other and opposite the two crossing groups of mutes in

VPA 9 / 6I0 / 0245 209825/0284

Grooves lying on different levels are provided which, when in groups, extend parallel to one another * intersect with the grooves of the other groups and which each receive at least two connection elements of a component are used to electrically connect bridges. " In this way, in addition to the multiple strips inserted in terms of coordinates, electrical connection lines or Bridges are laid that are only in other planes and angular positions, but in principle in a very similar way as the multiple strips are automatically insulated as blank parts and placed correctly in the grooves of the carrier plate.

Finally, according to a further development of the invention those inlaid in the grooves opposite the assembly side of the components Multiple stripes by means of granulation or thermoplastic Deformation of the material of the carrier plate mechanically fixed at at least two points along a groove be. This measure ensures that the multiple strips arranged on the underside of the carrier plate and any connection lines and bridges that may be present during the assembly of the components and during transport up to Dip soldering cannot fall out of the grooves.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing. Included demonstrate:

of the same type as the multiple strips 11-14 So that these multiple strips 21 to 23 during assembly, that is to say with the one drawn ventilation-appropriate position of the carrier plate not out of the Bhiten 18 to 20 can fall out, these multiple strips are, for example, due to granulation or thermoplastic deformation of the grooves 18 to 20 mechanically fixed at some points along the groove. Since the soldering lugs 3 of the multiple strips extend in the same direction, openings 24 to 27 are on the carrier plate for the passage of the Soldering lugs 3 of the horizontally extending multifunctional strips 11 to 14 are provided. These openings 24 to 27, which In the embodiment shown, it is designed in a specific manner that can be seen more clearly in FIGS are used to accommodate certain connection elements of a component (not shown), for example the contact connections of relays, whereby when inserting these connecting elements into the openings the associated soldering lugs of the multiple strips 11 to H are mechanically pretensioned to the connection elements and are prepared for a later dip soldering by intimate contact. Furthermore are Holes 28 to 32 are present in the carrier plate through which further connection elements of the component not shown pass through the carrier plate and on the opposite one Side with the soldering lugs of the vertical ones, not shown, pointing outwards from the carrier plate Touch multiple strips 21 to 23. In order to also have one for later soldering in the embodiment shown To ensure the necessary intimate contact of these parts, the soldering lugs 3 are angled accordingly, so that the connection elements connected, for example, to the field winding of a relay after the passage of the Carrier plate inevitably hit the inclined soldering lugs and deflect them to the side under pretension. Further-' there are grooves 8 to 10 in the carrier plate,
