Electromagnetically actuated switching device and method for producing its connection contact points

The invention relates to an electromagnetically actuated switching device with connection contact points for the coil connection of a magnet system and with further connection contact points for one of this magnet system actuatable switch contact part; the invention also relates to a method for producing the terminal pads for the said switching device.

For switching devices of the type mentioned, the market has different training requirements of said connection contact points. Especially with switching devices with a lower switching capacity than Connection contact points formed by screw connections

desired, but also those that are used as Steckanschluli are formed and finally also switching devices with connection contact points, which are designed as soldered connections are. In addition, differently designed connection contact points are often found on one and the same switching device are desired, i.e. terminal contact points formed as soldered connections, for example for the coil connection and connection contact points designed as screw connections for the switch contact part. However, combinations other than those just mentioned with regard to the formation of the connection contact points are definitely also possible needed. These special requirements of the market mean for the manufacturer of such switching devices an unusual amount of inventory when you have all conceivable or even common types of Must stockpile connection contact points or combinations thereof. An order-related assembly, on the other hand has the disadvantage of a comparatively long delivery time and also the even more significant Disadvantage of a possibly small number of pieces, based on the possible output capacity of modern, possibly semi-automatic or even automatic assembly systems.

The object of the invention is to find a way to meet the respective customer requirements as soon as possible to be able to, in this case, however, an excessive storage of devices of different training or respectively to avoid combinations of differently trained connection contact points and still the To be able to manufacture and assemble the switching devices in such numbers that one largely automated manufacturing and assembly are appropriate.

To solve this problem, the invention proposes that the connection contact points both for the coil connection as well as for the switch contact part each from a base contact piece provided with an internal thread and to form a line connecting member to be connected therewith, here as a line connecting member either one for a screw connection, for a plug connection or for a solder connection use and arrange the mentioned base contact pieces on the switching device as far as accessible and the line connection elements to train all of the connection types mentioned so that the connection between base contact pieces and line connecting members on the otherwise fully assembled or at least almost fully assembled Switching device can be produced.

Such constructive measures have the consequence that switching devices are assembled and stored in large numbers can be and now only the line connection members in the respective desired type of connection in the device must be introduced. This is a comparatively very short and also simple one Assembly process that can not only be planned into production at very short notice, but also beyond that is also economically feasible for comparatively small series or quantities. Another advantage is that said connection between base contact pieces and line connection members also - depending on customer requirements - can be produced in different ways, how will be explained further below.

For the design of the base contact pieces, it is proposed that these be U-shaped and their free ones

Mp. No. 527/85, *.!. '. ^'. · * '-.' 03/20/1985

To make U-legs narrower than their middle Connecting leg. This design proposal not only helps to save material, it also opens up In addition, there are also inexpensive mounting options for the basic contact pieces. For example further proposed the free U-legs of the base contact pieces on their two side edges to be provided with a saw toothing. As a result, a self-adhesive mounting of the base contact pieces is particularly useful easier way to achieve, namely when these toothed lateral surfaces of the Ü-legs with adjacent ones Claw wall parts.

It is also proposed that the base contact pieces should have one in the middle of the area of the central leg to provide a passage provided with an internal thread. This has the advantage that as a base contact piece actually a one-piece part can be used ^. Instead, it is also possible, for example in the center of the area to provide an opening of the middle leg of the base contact pieces, which is used to receive a nut part, for example in the form of a widened or annealed nut, or instead for a combination with a washer nut, which is not attached directly in the opening of the associated base contact piece is, 'rather is supported in an adjacent housing part and is secured against rotation therein. This latter embodiment does not have the advantage of being in one piece, but it can nevertheless possibly be more economical are made, since such nut parts represent pronounced machine parts and very can be manufactured or obtained inexpensively.

Mp. No. 527/05 .: .. *. />'""..' * .. "... · 03/20/1985

Another advantageous design proposal According to it, the base contact pieces are designed specifically for the coil connection on one of their free U-legs to be provided with an extension serving as a solder connection, the latter preferably with an offset can be provided. This creates a particularly simple contacting connection between the Base contact piece and the corresponding SpulenanschluJo to be made before the soldering process, without having to do this additional parts would be required. For the base contact pieces specifically for the switch contact part, the Made advantageous proposal to one of their free U-legs directly as a switching contact or as Provide laterally protruding molding serving switching contact carrier. In other words: these base contact pieces serve at the same time as fixed contact pieces, which interact with corresponding contact bridges. The base contact piece and the fixed contact piece thus form a separate contact rivet, with the exception of a possible contact rivet one-piece part, which also offers an advantage in terms of assembly.

To expediently implement the basic idea, it is also proposed to accommodate and hold the Base contact pieces for the coil connection on a 'flange of a coil body of the magnet system strip-like Provide projections, which each have an axially extending, continuous or at least to the free At the end of the molding, they have an open recess, approximately round or polygonal in cross-section, and at their outer one Contours also each have at least one groove running in the longitudinal axial direction for adhesive reception a free leg of a base contact piece included. In this at least one groove, one of the

Engage free U-leg of the assigned base contact piece and, especially if it has lateral teeth, claw into this groove, which provides a very permanent and vibration-proof mounting of the base contact piece.

In order to accommodate and hold the base contact pieces specifically for the switch contact part, it is in turn proposed - according to another design proposal - to form surfaces located on a housing part of the switching device between separators with an approximately central opening and with lateral recesses for the adhesive accommodation of the two free legs of a base contact piece to be assigned. In this way, a precise holding of the individual base contact pieces can be achieved in a simple and yet very effective manner, which, as just explained, can at the same time also form the required fixed contact pieces. In addition, there is the advantage that such base contact pieces, including their fixed contact piece components, can under certain circumstances be easily removed from the outside and replaced by others, which can sometimes save the replacement of a complete switching device, at least until replacement parts are procured or the like.
25th

After the switching device has been installed, which is complete or at least except for the line connection elements is at least almost completely finished, the device can be stored and then in due time to the final Completion can be retrieved again. The decision is now made regarding the type of line connector to be selected hold true. Line connecting members serving as screw connections are here in an

known way from a head screw and a rectangular, roof-shaped canted, preferably on Formed screw head fixed clamping screw, the screw shaft from the internal thread of the associated Base contact piece is added. In contrast to known comparable switching devices, in the present However, the determination of whether and, if applicable, where a screw connection is to be arranged, is only shortly before Delivery of the otherwise previously completed device. The elements for the However, screw connections are very well known per se - it has already been said.

Alternatively, a plug connection can also be provided for some or for each of the connection contact points, according to an advantageous design proposal, the line connection members designed as a plug connection on her one who? Acceptance of a plug-in sleeve Serving connection end designed in a known manner spade-like and preferably with a However, a slot opening into a small bore is provided at its opposite other end they have a fastening extension.

Another advantageous proposal going in the same direction aims at the formation of the solder joint formed line connection members from, namely to form these pin-like at their connection end, if necessary forming a solder lug or the like, and now, towards the opposite end, one here too Provide fastening extension, which at least in the area of the transition from the pin-like shape a shows significant broadening.

Advantageous design options both for those designed as a plug connection and for those designed as a solder connection Line connecting members can be found in claims 13 to 18 and in the rest of the context explained in detail with the description of the exemplary embodiments which follows below.

The method proposed according to the invention is now also designed in accordance with the above explanations for the production of connection contact points for a switching device of the type in question here: it is provided here, the base contact pieces without line connecting members in the course of the assembly of the switching device to be inserted into this, then after complete excluding the line connecting members - or at least Almost complete assembly and, if necessary, intermediate storage of the switching device for the individual Connection contact points to select or set desired line connection members, with an one and the same switching device line connection members of different types can be provided, that is, such with a screw connection, a plug connection or a solder connection, and finally the selected line connection members with the assigned base contact pieces on, as I said, assembled or almost completely assembled To connect switching device, the connection preferably by pressing, screwing or is made by electrical resistance welding.

Based on the embodiments shown in the drawings for the process of the last assembly step and for the design options for both the base contact pieces and the line connection members, the idea of the invention and advantageous implementation options are to be explained and clarified again. ^v

Figure 1 illustrates one already with a winding 10 provided bobbin 11 for the magnet system of an electromagnetic switching device. At the bobbin 11, starting from its bobbin flange 12, which is located on the left in the illustration Strip-like formations 13 and 14, as the name suggests, molded. These strip-like formations 13 and 14 are each equipped with a continuous or at least deep opening 15 and 16, respectively and otherwise with lateral grooves, of which only the groove 17 on the strip-like projection 13 is recognizable. Above the strip-like projection 13 is a - not yet connected to the coil body 11 - Basic contact piece 18 shown, which is attached to the projection 13 manually or by means of a device can be. Here, the free leg 19 located further forward in the illustration fits into the already mentioned groove 17 and claws here due to the lateral saw teeth of this leg 19 in the groove 17. The other free leg 20 of the base contact piece 18 merely rests against the opposite one the groove 17 located wall of the strip-like projection 13, whereby a horizontal movement of the base contact piece 18 is avoided towards the viewer. A lateral horizontal movement game is avoided by the edges of the groove 17. A closer examination of the base contact piece 18 is also intended can still be made in connection with FIG. It should only be mentioned that the free end of the leg 19 of the base contact piece 18 ends in a bend 21 on which a connection end 22 of the winding 10 is attached and soldered. The other strip-like projection 14 is made with the same base contact piece

provided and the second terminal end of the winding 10 is attached to it in the same way, but this cannot be seen from this illustration. So much for the base contact pieces for the coil connection and their arrangement on the coil body 11.

Figure 2 illustrates a housing part 25 (more precisely said: an upper housing part) of the switching device already mentioned in the explanations for FIG. Recognizable are pairs of opposing separators 26 and 27 (only one has been numbered Separator pair), which are used to form individual niches in which the connection contact points to be ordered. In the lower walls 28 and in the side protruding towards the center of the housing part 25 Walls 29 of the individual niches are provided with recesses, which are used for receiving and holding Serve base contact pieces. Are recognizable in the individual Recesses 30 and round recesses 31, located on the side, in the illustration right of the round recesses 31 are also rectangular recesses, but due to the In the perspective representation, the recesses located in the raised walls 29 cannot be seen for the passage of fixed contact pieces on the base contact pieces are even shown in the illustration not recognizable, but imaginable when one takes into account the shape of the base contact pieces. These Basic contact pieces, of which only one is numbered - namely with the number 32 - are essentially U-shaped and also have an integrally molded switching contact or switching contact that serves as a fixed contact. a switch contact carrier. Such a base contact piece is - enlarged - again in FIG

Mp. No. 527/85. ·.,> £, * .- 20.03.1985

shown and will be explained in detail below.

The two opposite niches of the housing part 25 which are located on the far left in the illustration are shaped differently in their bottom area 33 than the other niches, namely they only have a large rectangular one or square recess 34 through which the base contact pieces 18 on the bobbin 11 (see Fig. 1) protrude or are accessible.

FIG. 3 illustrates - like the other figures in a perspective view - a largely fully assembled switching device which, as far as the externally recognizable parts or assemblies are concerned, is composed of the already explained housing part 25 (see FIG. 2) and a housing base 35. On the housing part 25, the base contact pieces 32 for the switching part and one of the base contact pieces 18 for the coil connection can be seen in the niches open to the viewer. A switching device that has been completed so far can be manufactured in advance and then stored, but it is not yet completely complete because the line connection elements are still missing. Optionally, line connection elements designed as screw connection 30 or as plug connection 37 or finally line connection elements designed as solder connection 38 can be assigned to the individual base contact pieces. It is entirely possible here to assign line connection members of different types to the individual connection contact points. In practice, the most common case will occur that all connection contact points have the same type of line connection elements

Mp. No. 527/85 .... - * · Γ ^: .. ^: -, J ' \. ^: . ", · 03/20/1985

be provided or - less often - the case that the Connection contact points for the coil connection (in the illustration according to FIG. 3, the two on the far left of each other opposite connection contact points) must be of a different type than the others, the switch contact part assigned connection contact point.

After determining the special line connection elements required at the individual connection contact points these are now attached to the otherwise fully assembled switching device, with the screw connection 3b formed line connection glxeder into the provided on the individual base contact pieces 18, 32 internal thread are screwed in, the line connection members formed as a plug connection 37 or as a solder connection 38 however, either with pin-like mounting projections in the said internal thread pressed in, optionally additionally or only welded to the associated base contact pieces or screwed to them if the fastening extensions are provided with corresponding fastening openings are C see Figures 7f and 8f).

The procedure just described also corresponds to the method characterized in claim 19.

The other figures represent - on an enlarged scale compared to Figures 1 to 3 - advantageous training options both for the base contact pieces and for the different types of line connectors.

Figure 4 shows a base contact piece 40, which the one in Figure 1, provided there with the number 18, is the same. As a form element, this has a base 35

Mp. No. 527/85.!. '. r £ '\, *. ... 03/20/1985

contact piece 40 has an approximately rectangular central leg 41 as well as bent free U-legs 42 thereof and 43, which incidentally are significantly narrower than the central leg 41. Approximately in the center of the surface of the central leg 41 is provided with an internally threaded screw opening 45 which is the receptacle of Line connectors is used. The U-leg 42 has at its free end an angled one which serves as a solder connection Extension 46, which is used for the solder connection of a winding end 22 of a winding 10, see this Figure 1. It should not go unmentioned that both narrow sides of both free U-legs 42 and 43 with a Saw teeth 47 are provided, the meaning of which has already been explained, i.e. these saw teeth serves to claw the base contact piece, for example, in appropriately dimensioned grooves 17 (in FIG. 1).

Base contact pieces according to the just explained Figure 4 are used to form connection contact points for the Connection of coils for electromagnetic switching devices.

Figure 5 illustrates a base contact piece 48, which roughly corresponds to those (32) indicated in FIG. Also this basic contact piece has a U-shaped overall contour, containing a central leg 49 and free U-legs 50 and 51. And This middle leg 49 is also provided with a fastening opening 52, but this is not directly is provided with an internal thread, but is instead combined with a separate nut part 53.

This nut part 53 can be designed as a weld-on or rivet nut, depending on the design of the receiving surface for such a base contact piece 48, however, even one with the base contact piece is not particularly sufficient connected washer nut. Contains one

Mp. No. 527/85.; .. * .. "JPSV",. ' '.-'... * March 20, 1985

Mounting surface, for example, a hexagonal recess that corresponds to the outer contour of the washer nut 53, a separate connection between the base contact piece and the nut part is unnecessary. The two U-legs 50 and 51 are also significantly narrower formed as the adjacent center leg 49 and in the rest are also provided with saw teeth 54 on their two narrow sides. In the same plane as the U-leg 51 is also a previously unmentioned projection 55 with an opening 56, which the latter is used to accommodate a switch contact (not shown). This formation 55 forms, together with the switching contact mentioned, a fixed contact piece, which is therefore part of the base contact piece 48. Instead of a separate switching contact, a bulge can be provided instead of the opening 5b, especially when the power switching part of a switching device does not have to be switched with large powers is acted upon and, accordingly, massive silver contacts or the like can be dispensed with.

Basic components as shown in FIG. 5 serve - as already stated - the connection contact points for the switch contact part of a switching device.

Now to the line connectors, which are the base contact pieces are to be assigned.

FIG. 6 shows a screw connection 57 Line connection member, which is composed of a cylinder head screw 58 and a roof washer 59. Such line connecting members are known and it is also customary to press the roof panes 69, too

Mp. No. 527/85. '* \.' Wtx. ^: \ .- * .., March 20, 1985

washers or the like called to fasten so close to the head of the cylinder head screw 58 that when unscrewing the cylinder head screw 58 the roof disk 59 is "taken along". Like this fastening of the roof pane near the screw head is not of interest here, rather there is numerous suggestions from the known state of the art.

Instead of a screw connection, however, there is now also the arrangement of a line connection element designed as a plug connection possible on the individual base contact pieces.

Examples of training for such soldered connections are illustrated in FIGS. 7a to 7f. The figure 7a shows a particularly simple embodiment of a line connection member designed as a plug connection bO. This plug-in connection 60 and also the plug-in connections to be described below sit down - so is assumed to be composed of two longitudinal areas, namely one that is directed upwards in the illustration, the Receiving a connector sleeve serving connection end 61 and a fastening extension pointing in the opposite direction 62. In this exemplary embodiment, the "division" is the longitudinal area of the plug connection not so obvious, since this fastening extension 62 is only an extension of the connection end 61 in represents completely the same width. In such an embodiment, the plug connector 60 is with his after downwardly directed end face 63 placed on the base contact piece assigned to it and then - for example by means of electrical resistance welding or electron beam or plasma welding - with his Base contact piece butt welded. This is particularly possible when the manufacturing material

Mp. No. 527/85 ..... '- ** K · ..' * .- · * March 20, 1985

has a certain minimum thickness, i.e. the front side 63 actually offers a sufficient welding area. The connection end 61 of the plug connector 60 is "spade-like" in a known manner and with an in a small bore 64 opening slot 65 is provided.

A second embodiment for a plug connection is shown in FIG. 7b, in which a plug connection

66 is recognizable. Its connection end is designed completely the same as that according to FIG. 7a and therefore also provided with the same number 61. This plug connection is also at its opposite end to the connection end 61 directed end equipped with a fastening extension 67, which, however, is significantly narrower than the connecting end 61. Such a fastening extension

67 is, with a suitable choice of its width, suitable for this in a fastening opening or in a To be inserted or pressed in thread of a base contact piece. Such a compression can already be sufficient to hold the plug connection 6b permanently, but it can also be an additional Welding can be provided, with the shoulder surfaces 68 and 69 can serve as butt welding surfaces.

Another embodiment variant is illustrated in FIG. 7c. A plug connection 70 can be seen here, the connecting end 61 of which is in turn identical to the connecting ends of the plug connections and connectors explained above therefore again bears the same number 61. The attachment extension of this plug connection 70 has in its (not yet deformed) planar initial shape has a double-T-shape, the transverse webs 71 and 72

Mp. No. 527/85.:!. ·., ^: * &, '"\ ^.: **, ..," 20.03-1985

are connected to one another via a narrow connecting web 73. This connecting web 73 is in one Deformation process folded roughly in the middle, whereby the now formed free end of the attachment extension, as can be seen, is given a pen shape. The transverse web originally located at the free end of the attachment extension 72 is also roughly right-angled, pointing away from the rest of the contour of the attachment extension, angled and forms a kind of support surface, which can very well serve as a welding surface to weld the plug connector 70 to an associated base contact piece. The pen-shaped area of the The folded connecting web 73 is inserted into a fastening opening on the base contact piece and serves as a guide or fixing the position of the plug connector 70, but it can very well also be a Pressing take place or be provided, so that under certain circumstances an additional welding can be dispensed with.

FIG. 7d shows yet another possible embodiment for a plug connection. This plug connection 74, at its top in the illustration directed connection end bl the previously described Similar to plug connections, is at its downwardly directed end in the initial form with a longitudinal slot provided and the lugs 75 and 76 now formed on both sides of the longitudinal slot are then in opposite direction has been angled, with the angled outer surfaces 77 and 78 as mounting surfaces serve, which can be connected to an assigned base contact piece, i.e. preferably weldable are. A guided tour through a pen-like extension, like this one in the two previously described Embodiments are given, this plug connector 74 does not have.

Mp. No. 527/85,. "., ^ S yf .. '". S'".. * ... * 03/20/1985

A plug connection 79 shown in FIG. 7e with a connection end 61, as previously described, is only in the area of its attachment extension angled towards a single side and the outer surface 80 of the angled portion 81 now again serves as a connecting surface with a basic contact piece, i.e. primarily as a welding surface.

A plug-in connection of identical design in principle is shown in FIG. 7f; The only difference to the plug connection explained above is that in an angled tab 83, the length of which is slightly larger than that of the bend 81 in the plug connection 79, a fastening opening 84 is present is. Such a plug connection 82 can therefore optionally be welded or screwed to a base contact piece Both types of connection can of course also be used together. One becomes the latter approach however, only use them in special cases of need, as the effort involved is correspondingly great. In any case, the screw connection enables the plug-in connection to be fixed in position, in a similar manner as is the case with the plug connections according to FIGS. 7b and 7c.

Finally to the line connection members designed as solder connections, the simplest version of which is illustrated in FIG. 8a. Also these solder connections are subdivided - at least theoretically - into two longitudinal areas, namely into a connecting end 85 with a pin-like shape and, towards the opposite end, in a fastening extension 86. Taken together these longitudinal areas form a line connection member designed as a solder connection 87. One of those designed solder connection 87 is to be connected in the same way with an assigned base contact piece referring to

Mp. No. 527/85,. * ..%. · 2Θ *. * '..' · .. ■ ...- 20.03-1985

to be welded, as is the case with the plug connection 60 according to FIG. 7a. So it will too here the end face 88 of the fastening extension butt with the associated base contact piece welded. With regard to the connection end 85 of this solder connection 87, it should also be noted that it is at its free end 89 may have a head-like widening, which are used to receive a solder drop and are similarly shaped can be like the bend 46 in Figure 4. The production However, a solder connection does not need such a widening, but it is very sufficient to let the connecting end 85 just run out at its free end 89, as shown. as well It may be useful to add a small one that serves as a soldering lug in the head-like widening 89 shown To attach opening, but this is not shown.

With regard to the further configuration possibilities of line connection members designed as solder connections according to FIG FIGS. 8b through 8f actually no longer require any separate explanations, rather it can be stated that the respective connection ends correspond to those of the solder connection 87 in FIG. 8a and therefore all are marked with the number 85. The attachment extensions correspond in turn exactly those of the plug connections shown in the figure opposite and are also in the same way and Way connected with associated base contact pieces.

For the sake of order, the individual line connection members designed as soldered connections are numbered and listed below:

FIG. 8b shows a solder connection 90, FIG. 8c shows a solder connection 91 " FIG. 8d shows a solder connection 92, FIG. 8e shows a solder connection 93 and FIG. 8f shows a solder connection 94.

At the beginning of the description of the figures it was already indicated that the line connection members shown are and the base contact pieces are also only exemplary embodiments. Manifold in terms of shape or with regard to the dimensional proportions deviating design options are conceivable and feasible without to leave the inventive idea.

Finally, it should not go unmentioned that the inventive method and the proposed measures are not just a choice as to the type of welding for the individual Allow connection contact points for an otherwise practically fully assembled switching device, but beyond that also a choice within several embodiments of one and the same type of connection open. For example, a customer can choose for himself which particular embodiment of a plug-in connection is required (see Figures 7a to 7f) he wants to have on his devices. One such additional option can very well cause particular thermal or mechanical loads on the switchgear or switchgear take their connection contact points into account and thus further improve the efficiency of the invention.
