Description

Multipole plug insert - in particular for installation in a plug housing, with mounting flanges being provided on the plug insert and fastening bases on the plug housing - the plug insert comprising a first part which has a first number of contact inserts located in insertion openings, and a second part which comprises a second, compared to the first multiple number of connection contacts seated in connection openings, each contact insert in the first part being permanently conductively connected to at least two connection contacts in the second part, and in the second part in each case between two adjacent groups of at least two connection contacts, each with a contact insert in the the first part are permanently connected, an opening is provided into which a contact clip can be clamped. which establishes a conductive connection between the two adjacent groups of at least two connection contacts.

Plug inserts of the type mentioned above are used in a variety of ways in the field of industrial control and regulation. They are often combined into several in a parallel arrangement in switch boxes. The respective plug insert or the respective add-on housing is inserted into the control cabinet in such a way that plug contacts - pins or sockets - point outwards for connection with a mating connector, while the desired wiring is carried out on the inside via corresponding connection contacts. The connection contacts can be screw contacts, flat plug contacts, crimp contacts, spring-loaded Clamp contacts, solder contacts or the form of termi-point (connection for clamping shoe) or wire-rap (connection for winding technology).

There is often the requirement that a contact pin or a contact socket is occupied several times, i. H. there is a need to allow multiple wiring for each contact pin or socket. The possibility of realizing this with a single connection contact is extremely impractical, especially for soldered connections almost impossible. In addition, such a type of multiple assignment according to VDE and the regulations of the German Federal Railways is not permitted. For industry, the relevant company standards essentially apply; at least such an assignment is not practiced. In the case of control currents, but not in the case of power currents, double assignment of a connection contact can occur only with soldered connections if the connection wires are provided with soldering lugs beforehand.

From DE-A-35 22 797 a multi-pole plug insert of the type mentioned is known, in which in each case one plug contact element is connected to a plurality - ie in particular four - line connection elements. Bridge elements can be plugged onto adjacent line connection elements in such a way that all line connection elements of two adjacent plug contact elements are connected in an electrically conductive manner and are therefore at the same potential. Two of the previously available - a total of eight - line connection elements of two adjacent plug contact elements are thus occupied, so that now only a reduced number - six - remains free for conductors to be connected. When the connector is used, 25% of the available line connection elements are lost when a bridge circuit is made. Another disadvantage is that the manufacture of a bridge circuit with fully occupied Line connection elements is not possible.

Proceeding from this, it is an object of the present invention to provide a plug insert of the type mentioned at the outset which permits a variable multiple assignment of each contact pin or contact socket without complicating the connection or impairing the function and the operational reliability.

The solution to this is that the opening is designed such that when the contact clip is clamped in, the connection contacts remain unoccupied, so that they retain a connection possibility for connecting wires when the contact clip is clamped in.

In a favorable embodiment it is provided that each plug-in contact in the first part is in each case permanently conductively connected to two connection contacts in the second part. This corresponds to the need that occurs most frequently, so that in the following it will only be referred to. Deviating from this, it is also possible that each plug contact in the first part with a larger number, for. B. four connection contacts each, is permanently conductively connected in the second part if there is a corresponding need. According to the invention, the possibility is created to selectively establish conductor connections between a larger number of connection contacts with one another by means of suitable contact clips. This type of contact bracket will be discussed later.

In a favorable embodiment, the first part comprises two parallel rows of plug contacts and the second part four parallel rows of connection contacts, each of the same number. The main focus here is on add-on housings for 6, 10, 16 or 24-pin connectors. However, the idea according to the invention can also be applied to plugs which, for example, only have a number of plug contacts in the area of the first part and have several, in particular two rows of connection contacts in the second part.

The design of the plug insert according to the invention consists in that in the second part, an opening is provided between two groups of permanently conductively connected connection contacts, into which a contact clip can be clamped, which provides a conductive connection between the two adjacent groups of connection contacts which are always conductively connected to one another manufactures.

Instead of resilient contact brackets, which interact with fixed contact edges on conductors, inelastic contact pins can also occur, which interact with resilient contact edges of the conductors.

This makes it possible to meet a wide range of requirements by increasing the number of connection options for a contact pin or a contact socket to 4, 6, 8, etc., by producing conductor bridges in each case through the contact brackets mentioned. However, it should be noted that this reduces the number of additional plug contacts that can be assigned in the mating connector, ie. H. a proportion of the plug contacts is at the same potential.

According to a first embodiment, which is favorable for assembly, it is provided that the plug insert consists of at least two parts and is divided in the second part in a main division plane perpendicular to the through openings of the plug insert and has corresponding recesses into which conductor elements can be inserted, which can then be inserted can be fixed by assembling the two parts, and serve for the conductive connection of the plug contacts with the respective connection contacts. The two made of non-conductive material Parts of the second part of the plug insert can be secured against one another by means of clamp connections or adhesive connections.

According to another embodiment which is favorable for assembly, it is provided that the plug insert is composed of a plurality of disk bodies, each of which comprises the first and second part and whose main parting planes are parallel to the through openings of the plug insert and have the corresponding recesses, between which each other Conductively connected plug contacts and connection contacts can be inserted, which are then held by the assembly of two of the disk body. The large number of disc bodies made of non-conductive material can be connected to one another in a simple manner by means of rivet or screw connections which are pushed through transversely to the disc planes.

In a preferred first basic embodiment it is provided that the supervisory surface of the second part protrudes perpendicular to the insertion direction over the cross section of the first part, in this case it is particularly advantageous if the first connection surface provided with insertion openings for the contact inserts on the one hand and the insertion openings for the Connections provided second pads on the other hand are parallel to each other and point in opposite directions. In a further advantageous embodiment it is provided that the second connection surfaces are coplanar.

Another inexpensive embodiment is that the insertion openings for the contact inserts provided on the one hand and the second connection surfaces provided with insertion openings for the contacts on the other hand form an angle. It is according to the installation conditions possible that the second pads are offset parallel to each other or that the second pads are roof-shaped to each other and symmetrical to the first pad.

In the case of a plug insert of the type mentioned for installation in a plug housing with a through opening for receiving the plug insert, it is advantageously provided that the first part can be inserted into the inner cross section of the through opening and the second part adjoins the first outside the through opening and via the inner cross section of the Through opening protrudes.

With its first part, such a plug insert can be inserted into a conventional plug housing, in particular an add-on housing, so that in this respect no special adaptation of the surroundings of the plug insert is necessary. The first part of the plug insert can be equipped with contact pins or contact sockets in a known manner. The inventive design of the second part of the plug insert gives each contact pin or contact socket the possibility of multiple separate assignment with connecting wires. Due to the widened configuration of the second part of the plug insert, the corresponding connection contacts have the usual dimensions, in particular the usual distances between them, so that there is a very favorable access option.

Starting from a usually elongated rectangular shape of the plug inserts and the matching attachment housing, it is provided in a favorable embodiment that the first and second part of the plug insert have essentially the same length, so that the second part projects laterally in width across the attachment housing. There are several built-in housings for the plug inserts according to the invention installed in a control cabinet housing to set an increased lateral distance, but can be placed in several rows of this type with the usual usual distance of their end faces to each other.

Due to the shape of the plug insert according to the invention, it must be inserted into a suitable standard mounting housing from behind. Also preferably from behind, based on the add-on housing, the plug insert is screwed relative to the same. It follows from this that the wiring is expediently connected to the separate plug insert, which is then inserted from the wiring side into the attachment housing, which may already be installed in the control cabinet.

In an advantageous alternative basic embodiment it is provided that the cross section of the second part in the direction of its insertion openings corresponds approximately to the cross section of the first part perpendicular to its insertion openings.

In a favorable embodiment, it is possible for the first connection surface of the first part provided with the openings for the plug contacts to form an angle with one another with respect to the second connection surfaces provided with the connection openings for the connection contacts. It is possible that the first connection surfaces on the one hand and the second connection surfaces on the other hand form an angle of 90 ° with one another, the connection surfaces being coplanar with one another or that the first connection surface on the one hand and the second connection surfaces on the other hand form an angle between 90 ° and 180 ° with one another form.

With a plug insert of the aforementioned type for installation in a plug housing with a through opening for receiving the It is advantageously provided that the first part can be inserted into the inner cross section of the through opening and the second part adjoins outside the through opening with a cross section that can be passed through it.

Due to their shape, the aforementioned plug inserts can be inserted into an attachment housing either from the front or from the rear. A small tilting movement is required to guide the corresponding mounting flanges past the bases in the installation housing. In a preferred embodiment, however, it is provided that, when inserted from the front, the fastening flanges also rest on the front in the attachment housing, while when inserting from the rear, the fastening flanges rest on the base arranged in the attachment housing in the usual manner. Regardless of this, the screw connection can be carried out either from the front or from the rear, depending on whether the base is provided with a through hole and the reinforced screwed-on flanges are provided with a threaded hole or vice versa.

In addition to the fastening of the plug inserts in attachment housings described in detail here, it is also possible to screw directly into sheet metal shelves with corresponding mounting openings, the cross section of which corresponds to the inner cross section of an attachment housing. In addition, attachment to individual parallel carrier rails is also possible, with only the hole spacing of the fastening holes on the carrier rails having to be selected accordingly when fastening multiple plug inserts.

Preferred exemplary embodiments are represented by the subclaims.

Figures 1 and 4, 2 and 5 and 3 and 6 are described together below. The majority of the reference numbers mentioned can only be found in the enlarged representation of FIGS. 4, 5 and 6.

FIGS. 1 and 4 show a cross section through a conventional add-on housing 1 and a plug insert 2 according to the invention used therein. The plug insert 2 has mounting flanges 26 which rest on bases 38 in the attachment housing 1 and are connected to the latter by means of screws 27 shown only by means of center lines. The plug insert 2 comprises a first part 4 inserted into the through opening 3 of the attachment housing 1, and a second part 5 lying outside the same and projecting beyond the open cross section of the attachment housing 1. The first part 4 merges in one piece into a base plate 6 of the second part 5 . This has a side frame part 7. Inserts 8 are fitted into the frame part. In the first part 4, pairs of insertion openings 9 are provided, into which contact sockets 10 are inserted. These are in contact with conductor rails 11, which divide into first contact tongues 12 and second contact tongues 12 'towards the rear. The conductor rails 11 are held between the base plate 6 and the inserts 8. These parts can be jammed together. The previously mentioned parts are each provided in a symmetrical design with respect to a central plane E, two halves of the first part 4 and the base plate 6 being glued together in the middle. In the frame part 7 of the second part 5 a multi-perforated cover part 14 is inserted on the inserts 8, which is made in one piece. This holds four units of connecting contacts, each consisting of a holding plate 15, 15 ', a clamping screw 16, 16' screwed therein and a movable clamping tab 17, 17 'commit. When the clamping screw 16, 16 'is tightened, the clamping tab 17, 17' lies against one of the contact tongues 12, 12 ', so that a conductor can be clamped here. To adjust the clamping screws, 14 screw openings 18, 18 'are provided in the cover part, and insertion openings 19, 19' for inserting conductor wires. Contact brackets 20 can also be seen, the shape and function of which will be explained on the basis of the further figures. The plug insert 2 of the form shown here has a first connection surface 13 with the insertion openings 9 for the contact inserts and two parallel connection surface parts 22, 23, which are coplanar and symmetrical to one another, with the insertion openings 19 for connection contacts, the first connection surface 13 and the second pads 22, 23 are directed opposite to each other.

In FIGS. 2 and 5, details corresponding to those in FIGS. 1 and 4 are designated with the same reference numbers. The reference numbers are predominantly only entered in the enlarged representation according to FIG. 5. The top view of the add-on housing 1 can be seen, which has at its ends flanges 25 with through holes 24 for pushing through screws for fastening the housing to a switch cabinet housing or the like. In the through opening 3 of the attachment housing 1, fastening flanges 26 are screwed onto the base 38 in the through opening 3 by means of screws 27. Sheet metal parts are fastened on the end face to the plug insert 2, forming tabs 28, 29, one of which is equipped with a holding plate 30 and a clamping screw 31, while in the other only a threaded hole 32 can be seen. Earthing or protective contact conductors can be connected to these tabs. The plug insert 2, of which the second part 5 is visible, is partly shown in view, partly with the cover part 14 being broken away. The peripheral frame part 7 is shown without breaking out.

Parallel conductor rails 11, which branch into contact tongues 12, 12 ', can be seen under the broken-out area. In each case in association with these, clamping tabs 17, 17 'and clamping screws 16, 16' can be seen. The conductor rails each have laterally broken-out contact edges 33, into which contact brackets 20 can be snapped in and can be used to produce a conductive contact between two adjacent conductor rails 11 lying in parallel. These contact brackets 20 comprise resilient conductor legs 34 lying in parallel. Four of these contact brackets can be seen in section in the cutaway representation previously discussed.

The openings 18, 18 'for the clamping screws and the openings 19, 19' for inserting the conductor wires can be seen in the view. Between two rows of the openings mentioned, further openings 21 are arranged, into which the aforementioned contact brackets 20 can be inserted. In the view, four of the contact brackets 20 are shown with their handle parts 35 lying on top.

In FIGS. 3 and 6, corresponding details are given the same numbers as in the other figures. The major part of the details is only entered in the enlarged representation of FIG. 6. In detail, the attachment housing 1 with flanges 25 with the through holes 24 can be seen, in which the plug insert 2 is inserted as in the previously mentioned figures. This is inserted with its first part 4 in the through opening 3 of the attachment housing 1, and protrudes from the bottom of this. The upper wider second part 5 is shown in partial section. The through opening 3 has a central axis A. In FIG. 3, the holding plate 30 and the clamping screw 31 can be seen on the left. On average, the second part 5 with the frame 7, in which the cover part 14 is inserted precisely, recognize. Between the base plate 6 of the second part 5 and the cover part 14, the conductor rails 11 are inserted and held, on which the laterally broken contact edges 33 can be seen. The aforementioned openings 21, which are each arranged centrally between two conductor rails 11, penetrate the entire cover part 14 and continue in the base plate 6. In this the contact bracket 20 are inserted, which have a non-conductive handle part 35 and two resilient conductor legs 34, which are conductively connected to one another in a U-shape and are cast in the handle part 35. When inserted, the free conductor legs 34 run against a wedge 37 in the base plate 6, which ensures that the legs 34 make conductive contact with the contact edges 33 of two conductor rails 11 lying parallel to one another. In this way, a conductive contact between a contact socket or a contact pin and four, or if, as in the present case, for example, two contact brackets 20 are used, six connection contacts can be produced.

Figures 7 and 10 and 8 and 11 are jointly described below. Individual reference numbers can only be found in one or the other of the figures described together. Figure 7 corresponds to a section along the section line AB from Figure 8, Figure 10 corresponds to a section along the section line CD from Figure 11 and Figure 12 corresponds to a section along the section line AB from Figure 11.

In FIGS. 7 and 10, a plug insert 52 is shown partially (FIG. 10) or completely and inserted into a conventional add-on housing 51 (FIG. 7). The plug insert 52 has fastening flanges 76 which rest on bases 88 in the attachment housing 51 and are connected to the latter by means of screws 77. The plug insert 52 includes a in the through opening 53 of the Add-on housing 51 inserted first part 54, and a second part 55 lying outside of add-on housing 51 and projecting over its open cross-section. The lower section of the first part is formed by a contact insert 89, which is not shown in FIG. The first part 54 merges in one piece into the second part 55 in the sectional plane shown in FIG. 10. Openings 59 in the form of longitudinal recesses are provided in the plug insert 52, into which conductor rails 61 are inserted. Contact pins 60 are pushed onto these and crimped on at the bottom. The conductor rails 61 merge in one piece into connection contacts 67, 67 '. They also have middle contact tongues 62. The conductor rails 61 are punched out of sheet metal. The connection contacts 67, 67 'end in open insertion openings 69, 69' for suitable flat plugs. The contact tongues 83 are in the region of insertion openings 71 for contact brackets which will be shown later. Longitudinal bores 98 are formed in the plug insert 52, through which rivets 99 can be pushed for connecting several disk-shaped parts of the plug insert. The plug insert 52 of the form shown here has a connection surface 63 with the openings 59 for the contact inserts and two connection surface parts 72, 73 lying parallel thereto, which are coplanar and symmetrical to one another, with the insertion openings 69 for connection contacts, the connection surfaces 63 and the connection surfaces 72, 73 lie opposite to each other.

In FIGS. 8 and 11, details corresponding to those in FIGS. 7 and 10 are designated by the same reference numbers. The plug insert 52 is shown in a top view, the attachment housing 51, into which the plug insert 52 is inserted, being visible in FIG. The attachment housing 51 shows at its ends flanges 75 with through holes 74 for inserting screws with which the attachment housing 51 on a control cabinet housing or the like can be screwed. In the through opening 53 of the attachment housing 51, fastening flanges 76 of the plug insert 52 are screwed onto the aforementioned bases 88 of the attachment housing by means of screws 77. On the front side of the plug insert 52 are sheet metal tabs 79, against which a holding plate 80 can be pressed by means of a screw 81, and grounding or protective contact conductors can be clamped between the parts mentioned. FIG. 11 shows that the plug insert is made up of front-side washer bodies 56 ', 56' and further washer bodies 56 which are identical to one another. The designation disc body does not conflict with the fact that springs and grooves 96, 97 join into one another in the end faces. The insertion openings 69, 69 'can be seen between the disk bodies, in which the connection contacts 67, 67', which are designed as tongue-shaped sheet metal parts, are free. Standard flat plugs can be attached to these. The insertion openings 71, into each of which the contact tongues 83 protrude at the end, lie outside the section plane shown in FIG. If a contact clip is inserted into one of these openings 71, adjacent pairs of connection contacts 67, 67 'are conductively connected to one another via the establishment of a conductive contact between the corresponding contact tongues 83, e.g. B. the designated with 1 - 1 connection contacts with the parallel contacts, to which the numbers 2 - 2 are to be assigned mutatis mutandis.

FIG. 9 shows the plug insert 52 installed in the attachment housing 51 without any particular details, the first part 54 and the second part 55, which protrudes above, protruding from the through opening. It is indicated that the plug insert 52 as a whole is made up of washer bodies 56 of the same type with one another and two front washer bodies 56 ', 56 ", each of which is the entire height of the first and second Include parts. In contrast, the part of the plug insert for contact pins or contact sockets protruding from the through opening is in one piece. The central axis A of the through opening is particularly marked.

FIG. 12a shows a section through the upper part of the second part 55 of a plug insert. The insertion openings 71 can be seen, these being located between individual disk bodies 56, which, viewed in this sectional plane as well, engage one another with mold engagement means 94, 95, without this contradicting the designation as a disk body. The contact tongues 83 with openings 86 each lie on the end face in the insertion openings 71. Parts of the contact bracket 70 shown in detail in FIG. 12b engage in the openings 86 and have a non-conductive handle part 85 and two resilient conductor legs 84 which are connected to one another in a U-shaped manner and are cast on the handle 85. When inserted, expressions 87 of the conductor legs 84 snap into the openings 86 of the contact tongues 83. In this way, conductive contact is established between adjacent pairs of connection contacts 67, 67 '.

Figures 13a and 13b are described together below. The reference numbers mentioned are increased by 100 compared to corresponding parts from the illustration in FIGS. 1 and 4.

FIGS. 13a and 13b show a cross section through a conventional add-on housing 101a between 101b and a plug insert 102 according to the invention used therein. The plug insert 102 has screwed-on fastening flanges 126 which rest on bases 138a and 138b in the add-on housing 101 and are connected to the latter by means of screws 127. The bases 138a according to FIG. 13a are located to the front on the plug side in the housing 101a; the mounting tabs 126 are for assembly and screwing the plug insert 102 on them from behind. The bases 138b according to FIG. 13b are set back from the plug side deeper in the housing 101b; The assembly of the plug insert 102 and its screwing can be done from the front. The plug insert 102 comprises a first part 104 inserted into the through opening 103 of the attachment housing 101, and a second part 105 lying outside the same and fitting into the open cross section of the attachment housing 101. The first part 104 merges in one piece into a base plate 106 of the second part 105 . This has a lateral frame part 107. A cover part 114 is fitted into the frame part.
