Description

DESCRIPTION

Arrangement of a terminal block in a row with accessory holder

The present invention relates to an arrangement of a row terminal block with accessory holder according to the preamble of claim 1.

Row terminal block arrangements are used in many different applications.

DE 19748640 C1 describes a measurement separation terminal arrangement for the operation of current transformers, in which the contact rail parts are provided with conductor connections and contacts. For the connection of, for example, current meters or external voltages, a separation is necessary. For this, a separation circuit is used that interacts with the contacts.

Accessories for in-row terminal blocks consist of, for example, cross connectors, circuit breakers, etc., and are frequently used. In this regard, DE 299 14 020 U1 illustrates a mounting clip, in particular for a transverse connecting comb of a connecting terminal, with an essentially U-shaped clamping body in which a connecting rod can be accommodated. a transverse connecting comb.

In reality, these solutions have proven effective. However, it is desirable to further develop arrangements of in-row terminal blocks or in-row terminal blocks and to simplify and facilitate their handling, assembly and maintenance.

The objective of the invention is to solve this problem. The invention solves this objective through the object of claim 1.

An arrangement of a row terminal block according to the invention, in particular a row spacing terminal block, includes an accessory holder of an accessory member and an accessory member, the accessory holder having a housing for the accessory member and at least one plug section. In a first position, the accessory holder is mounted on the terminal block in a row, the accessory element being arranged in the housing of the accessory holder, wherein the accessory holder, when the accessory element is removed from the housing and is disposed in a functional position within or on the row terminal block, is mounted in a second position on the row terminal block or remains in the first position.

This creates a universal support for accessory elements (cross connectors, circuit breakers, markers, etc.). The accessory holder has the advantage that it can remain on the terminal block in a row, being able to be plugged, hooked or clamped from a first position to a second position and vice versa.

A particular advantage is that, for example, a cross connector can be separated from the terminal for testing purposes and does not need to be left somewhere in the connection cabinet, but can be kept securely in the terminal block in a row. .

Other advantageous configurations emerge from the other subordinate claims.

In one embodiment, the accessory holder features a handle, a U-shaped housing for the accessory element, consisting of a cross connector, and at least one plug section for mounting in at least one opening in the terminal block in row, at least one opening being provided for tools and/or test pins. In this context, a particular advantage is that already existing openings in the terminal block can be used in a row. The handle allows for advantageously simple manipulation.

In another embodiment it is provided that the accessory holder with the transverse connector in the first position is arranged in the opening of an outer row terminal of the row terminal block, wherein a connector housing and drive sections of the terminal block in line are blocked. In this way, unintentional use of the connector housing and, for example, opening of separating connectors of the drive sections can advantageously be avoided in a simple manner.

In yet another embodiment, the accessory holder without transverse connector in the second position is disposed in a raised opening of an outer row terminal of the row terminal block, with access being possible to the connector housing and drive sections of the terminal block. terminals in a row. When the transverse connector as an accessory element is removed from the accessory holder, the connector housing and the drive sections can be accessed, while mounting the accessory holder in the second position is possible. In this way, loss of the accessory holder is advantageously avoided.

In an alternative embodiment, the accessory holder has a plug housing with a receptacle for the accessory element, consisting of a cross connector, and with two plug sections for plug tabs of the cross connector. Advantageously, the transverse connector can be inserted into the plug housing.

It is particularly advantageous if the accessory holder with the transverse connector is arranged in the first position in a connector box of the terminal block in a row and blocks the connector box without electrically conductive connection, where projections of the housing Plug lock terminal block drive sections in a row, as no additional steps need to be taken to create clamping sections for the accessory holder. Furthermore, the advantage lies in the simple locking of connector housings and drive sections.

In another embodiment, the length of the plug sections of the plug housing is greater, preferably one and a half times greater, than the length of plug tabs of the transverse connector housed therein. In this way, the plug housing can be inserted with the cross connector into the connector housing, without an electrically conductive connection to the cross connector.

In another embodiment, the accessory holder without a transverse connector in the second position is arranged with a plug section or with a projection in a raised opening of an outer row terminal of the row terminal block, thereby enabling easy access. to the connector box and to the terminal block drive sections in a row. Also in this case, existing locations of the terminal block in a row can be used without additional modifications or adaptations.

In another alternative embodiment, the accessory holder is configured as a clamp element having a socket section with clamping projections, a honeycomb plate with a flange plate and a clamp arm with an end section, being formed between the end section and the honeycomb plate and its flange plate a housing for the accessory element, which consists of a transverse connector. This enables a compact component.

In another alternative embodiment it is provided that the accessory holder with the transverse connector in the first position is engaged in a marking channel of a marking section of the terminal block in a row by means of the plug section with the retaining projections. A particular advantage is to fix the accessory holder in a marker channel of a terminal in a row, since in this context it does not depend on the type of terminal whether the marker channels are in principle all the same and suitable for the same markers.

In this context it is provided that the transverse connector in the first position of the accessory holder blocks a connector housing and drive sections of the terminal block in a row. Advantageously, this is simple.

Alternatively, the transverse connector in the first position of the accessory holder may provide access to a connector box and drive sections of the terminal block in a row. This position is advantageous by a simple rotation of the transverse connector by 180° on the clamp element.

In another embodiment, the accessory holder without a cross connector in the second position may remain in the marking channel of the marking section of the in-row terminal block in the first position. This is advantageous, since the accessory holder does not have to be moved from one position to another.

But the accessory holder can also take the second position in the marker channel, since the accessory holder without cross connector can be engaged anywhere in the marker channel.

In another alternative embodiment, it is provided that the accessory support consists of a clamping device and has a base that has on its lower face a plug section with clamping projections, two elastic clamping jaws being arranged on its upper face, which are arranged one opposite the other and form a housing for the accessory element, which consists of a circuit breaker with a cylindrical body. This results in a compact and simple structure.

In another alternative embodiment, the accessory holder with the accessory element as a circuit breaker in the first position is engaged in a marker channel of a marking section of the terminal block in a row by the socket section with the fastening projections. Advantageously, this assembly is simple and saves space.

If the accessory holder without a supporting element such as a circuit breaker in the second position remains in the marker channel of the marking section of the in-row terminal block in the first position, a change to a second position is not necessary.

The invention is described in more detail below by means of embodiment examples with reference to the drawings. Shows:

The concepts “top”, “bottom”, “left”, “right” refer to the corresponding arrangement of the components in the figures.

Figure 1 shows a schematic perspective view of an arrangement 10 according to the invention of a terminal block 3 in a row with a first embodiment of an accessory holder 1 according to the invention. Figure 2 shows in this regard a schematic perspective view of the accessory holder 1 according to the invention according to Figure 1 without inserted accessory element 14.

Figure 3 schematically represents the accessory holder 1 with an accessory element 14/15 in a perspective view.

The arrangement 10 includes the in-row terminal block 3, the accessory holder 1 and an accessory element 14.

The terminal block 3 in a row presents a series of terminals 2.1,2.2, 2.3, 2.4 in a row, of which four are represented here in this example.

The accessory holder 1 serves to house and hold an accessory element 14. The accessory element 14 may consist, for example, of a cross connector 15, a circuit breaker 26 (Figure 11), a marker, a sign, or the like. Said marker or sign may include, for example, time-limited indications, such as information or one or more warnings.

The accessory holder 1 can be mounted, with the accessory element 14 or without accessory element 14, in different positions on the terminal block 3 in a row and removed again from it. When the accessory member 14 is arranged on the accessory holder 1, the accessory holder 1 is mounted in a first position, which is also designated as a parking position, on the in-row terminal block 3. Without the accessory element 14, the accessory bracket 1 is mounted in a second position on the terminal block 3 in a row. In this context, the accessory element 14 can be found in its functional position in the terminal block 3 in a row. Said functional position for the transverse connector 15 consists for example that, when the transverse connector 15 is inserted in the connector box 6, the transverse connector 15 produces an electrically conductive connection between at least two of the terminals 2.1,2.2, 2.3, 2.4 in a row. When the accessory element consists of a circuit breaker 26, its functional position in the row terminal block 3 is at a location provided for this purpose, which need not be described in more detail here. The case in which the accessory element 14 is a marker or a sign is excluded here.

The mounting of the accessory holder 1 on the terminal block 3 in a row to adopt the first and second positions takes place in each case by means of a plug-in and/or latching process. If the first position and the second position are located in different places on the terminal block 3 in a row, the accessory holder 1 is removed from the first position, for example pulled out, and then the accessory element 14 is removed from the holder 1 of accessory. Then, the accessory holder 1 is inserted into the second position without the accessory element 14. The adoption of the first position takes place in reverse order.

The different locations of the first position and the second position are further explained below.

The row terminal block 3 here includes the four row terminals 2.1, 2.2, 2.3 and 2.4, which in this example are configured as so-called spacer terminals. The function and structure of these terminals are described in the current state of the art.

The terminals 2.1, 2.2, 2.3, 2.4 in a row each have openings 4, 5 through which connections can be opened and closed using a tool, for example a screwdriver. These openings may also consist of test sockets. Five openings 4.1 are designated here by way of example; 4.2; 4.3; 4.4 and 5.

The terminals 2.1,2.2, 2.3, 2.4 in a row are provided with a connector box 6, into which a transverse connector 15 can be inserted to connect the terminals 2.1,2.2, 2.3, 2.4 in a row to each other.

The transverse connector 15 constitutes the accessory element 14 in this example.

In a functional state of the row terminal block 3, the row terminals 2.1,2.2, 2.3, 2.4 are not connected by the cross connector 15. The cross connector 15 is in a functional state of the row terminal block 3 in which the accessory holder 1 is mounted therewith in the first position of the accessory holder 1 in the terminal block 3 in a row.

For a test state, the terminals 2.1,2.2, 2.3, 2.4 in a row are connected to each other so that they conduct electricity via the transverse connector 15, which is first removed from the accessory holder 1 and inserted into the connector box 6 of terminal block 3 in a row. Then, the accessory bracket 1 without the cross connector 15 is mounted again in the second position on the terminal block 3 in a row.

If the cross connector 15 inserted in the connector box 6 in the test state is to be removed from the terminal block 3 in a row, the cross connector 15 is not deposited anywhere in the connection cabinet, but is inserted, placed and/or hooks it back onto the accessory holder 1. Then, the accessory bracket 1 with the cross connector 15 is mounted in the first position on the in-row terminal block 3 and is securely fastened to the in-row terminal block 3 by the accessory bracket 1.

The terminals 2.1, 2.2, 2.3, 2.4 shown here in a row, configured as separating terminals, each have a drive section 7 with an actuator, for example a lever.

Furthermore, the terminals 2.1, 2.2, 2.3, 2.4 in a row are each provided with a marking section 8. Marker channels 9 are provided in the marking sections for fixing, for example, markers. The marking sections 8 are all the same regardless of the type of terminals 2.1,2.2, 2.3, 2.4 in a row and are therefore all suitable for the same markers.

The accessory holder 1 of the first exemplary embodiment includes a handle 11, a housing 12 for the accessory element 14 and a socket section 13 for mounting on the in-row terminal block 3.

The housing 12 is configured in the shape of a U and has a base 12a on which two opposing arms 12b, 12c are mounted. The arms 12b, 12c of the U shape, in the open state, i.e. without inserted accessory element 14, are inclined towards each other under a certain pretension. The base 12a and the arms 12b, 12c define a housing space between them. The accommodation space may be provided with an inner profile 12d. In this example, the inner profile 12d has a rib that extends parallel to the longitudinal sides of the arms 12b, 12c on the inner face of one of the arms 12b, 12c. Two or more ribs may also be provided.

The handle 1 is formed with its lower face on the upper arm 12b of the housing 12 in the area of the connection of the upper arm 12b with the base 12a. The handle 1 protrudes from the upper arm 12b at a right angle.

The plug section 13 is arranged on the underside of the lower arm 12c and projects perpendicularly thereto. The plug section 13 has a square cross section and has rounded edges.

In this case, the accessory member 14 is the cross connector 15. The cross connector 15 includes a housing 16 with a clamping section 17 and a plug section 18. The clamping section 17 here has an outer profile 17a, which in this example consists of a slot, which corresponds to the rib of the inner profile 12d of the accessory holder 1. Two or more slots may also be provided, also on both sides of the clamping section 17. In this way, the advantage of a secure hold of the accessory element 14 in the housing 12 of the accessory holder 1 is obtained in addition to the clamping forces of the arms 12b, 12c of the accessory holder 1 subjected to a pretension.

The transverse connector 15 is inserted from the side or hooked from the front with its holding section 17 into the housing 12 of the accessory holder 1, the rib of the housing 12 engaging in the groove of the holding section 17. Removal of the cross connector 15 occurs by laterally pushing or pulling the cross connector 15 out of the housing 12.

The plug section 18 of the transverse connector 15 here has four electrically conductive elastic plug tabs 18a, 18b, which are connected to each other so as to conduct electricity within the housing 16. The outer plug tabs 18a are designated with the reference symbol 18a, the interior ones have the reference symbol 18b.

The dimension of the arms 12b, 12c of the housing 12 of the accessory holder 1 in the longitudinal direction of the edges of the arms 12b, 12c is here approximately half as large as the length in the longitudinal direction of the edges of the section 17 fastening section of the transverse connector 15. However, this dimension of the arms 12b, 12c may be larger, for example corresponding to the length in the longitudinal direction of the edges of the fastening section 17 of the transverse connector 15.

In this case not shown, but easily imagined, the accessory holder 1 can have two plug sections 13 with which it can be inserted, for example, into the openings 4.1 and 4.4 of the terminals 2.1 and 2.4 in a row.

Figures 4 and 5 show schematic perspective views of the arrangement 10 according to the invention according to Figure 1 in different positions of the accessory holder 1. Figure 4 represents the accessory support 1 with the accessory element 14 as transverse connector 15 in a first position. A second position of the accessory holder 1 is shown in Figure 15.

In the first position shown in Figure 4 of the accessory holder 1 together with the accessory element 14 (cross connector 15) attached thereto, the accessory holder 1 is inserted with its socket section 13 into the opening 4.4 (see Fig. Figure 1) of the terminal 2.4 in a lateral or outer row and is held firmly in position by clamping forces between the opening 4.4 and the plug section 13.

In this parking position, the transverse connector 15 covers with its housing 16 the connector box 6 of the row terminal block 3 and with its plug section 18 the drive section 7 of the row terminal block 3. Thus, neither the connector box 6 nor the drive section 7 are accessible or operable in the above-described operating state of the in-row terminal block 3.

If the cross connector 15 is to be used for the test state of the in-row terminal block 3, first the accessory holder 1 is removed from the first position together with the cross connector 15, the cross connector 15 is removed from the housing 12 of the accessory holder 1, for example, by lateral extraction from the housing 12, and is inserted into the connector box 6. Then, the accessory holder 1 without the transverse connector 15 is inserted with the plug section 13 into a raised opening 5, which is located on a higher plane than the other openings 4.1, 4.2, 4.3, 4.4, of the terminal 2.4 in outer row. In this second position, the accessory holder 1 does not constitute any obstacle to access to the connector box 6 or to the drive section 7 of the in-row terminal block 3.

Figure 6 shows a schematic perspective view of a second embodiment of the accessory support 1' according to the invention. Figures 7 to 9 represent schematic perspective views of an arrangement 10 according to the invention with the accessory support 1' of the second embodiment according to Figure 6.

The accessory holder 1' of the second embodiment is intended to be mounted on the marking section 8 of the terminal block 3 in a row. This accessory holder 1' is configured as a clamp element 19 and includes a base plate 19a, side plates 19b, 19c, cover plates 19d, 19e, a honeycomb plate 20 with a connection 20a and a flange plate 20b, as well as a clamp arm 21 with an end section 21a.

On the underside of the base plate 19a, a plug section 23 with two outwardly bent clamping projections 23a is mounted like wings. In this way, the plug section 23 is shaped so that the clamping projections 23a engage in the marking channels 9 of the marking section 8 of the terminal block 3 in a row and constitute a firm hold of the clip element 19. as accessory holder 1 ' on terminal block 3 in a row (Figure 7).

An upwardly projecting side plate 19b, 19c is formed on the short sides of the base plate 19a. On the free edges of the side plates 19b, 19c, the cover plates 19d, 19e are mounted in such a way that they constitute a kind of roof, being joined together at their free ends. Two narrow cover plates 19e are mounted on the front side wall 19b, which define a free space between them. The connection 20a protrudes upwards at the edge of the free space in the plane of the front side plate 19b and is connected at its free end to the honeycomb plate 20. The honeycomb plate 20 is here approximately square. At its upper free end, the flange plate 20b is mounted bent 90° inwards. In this way, the honeycomb plate 20 and the flange plate 20b form an L-shaped profile.

On the rear cover plate 19d, the gripper arm 21 is mounted in a corner area, and it extends approximately in a straight line in the plane of the rear cover plate 19d away from it. An end area of the gripper arm 21 is bent approximately 90° upwards and has the end section 21a, which is itself mounted bent approximately 90° rearwards. A housing 22 for the accessory element 14 is formed between the end section 21a and the honeycomb plate 20 and its flange plate 20b. This is shown in Figures 8 and 9 and is explained in more detail below.

Figure 7 shows arrangement 10 with accessory bracket 1' and terminal block 3 in a row. Here, the accessory holder 1' is without accessory element 14 and is in the second position.

The clip element 19 as accessory holder 1' is clamped in the second position in the uppermost of the two marking channels 9 of the marking section 8 of the terminal block 3 in a row, as already described above. . In this context, the clamp arm 21 protrudes above the area of the front openings 4 of the terminal block 3, in the center between the terminals 2.2 and 2.3 in a row. This position is possible because the gripper arm 21 is arranged offset in the corner area of the rear cover plate 19d of the gripper element 19, as already described above.

Figure 8 shows the arrangement 10 as in Figure 7, but with the accessory support 1' with the accessory element 14 and the terminal block 3 in a row. The accessory support 1' with the accessory element 14 is in the first position, where, in this example, the first position corresponds to the second position and differs in the accessory element 14 used.

In this example, the accessory element 14 is also the transverse connector 15 already described above. This is housed in the clamp element 19, which constitutes the accessory holder 1', in such a way that the housing 16 with the clamping section 17 is locked between the honeycomb plate 20 and the end section 21a of the clamp arm 21. by means of a spring tension force of the clamp arm 21 in the housing 22 (see Figure 6). Due to the offset mounting already described above of the clamp arm 21, it is arranged between the two central elastic plug tabs 18a of the plug section 18 of the transverse connector 15.

In this context, the edge of the clamping section 17 is included in the flange section 20b of the clamp element 19. Furthermore, the housing 16 and the holding section 17 of the transverse connector 15 rest on the rear cover plate 19d of the clip member 19.

The mounting of the clamp element 19 by its plug section 23 with the clamping projections 23a on the marking section 8 of the terminal block 3 in a row arranged in an oblique position allows the cover plate 19d to extend in a plane parallel to an imaginary surface plane of the terminal block 3 in a row. In this way, the plug section 18 is arranged above the drive section 7 and the connector box 6 of the terminal block 3 in a row and blocks access thereto.

In the arrangement shown in Figure 9, the transverse connector 15 is inserted rotated 180° into the accessory support 1''. This second position of the accessory support 1' corresponds here to the first position of the accessory support 1' up to the transverse connector 15. Also in this case, the transverse connector 15 is arranged between the end section 21a and the honeycomb plate 20 of the clamp element 19. The flange section 20b presses the housing 16, and the end section 21a surrounds an edge of the holding section 17 of the cross connector 15.

The housing 16 rests on the front cover plates 19e.

The plug section 18 of the transverse connector 15 is arranged above the marking section 8, the narrow connection 20a being here between the two central elastic plug tabs 18a of the plug section 18 of the transverse connector 15.

In this position it is possible to access the drive section 7 and the connector box 6 of the accessory support 1'.

Here the position of the accessory holder 1' is not modified, but the position of the accessory element 14, that is, of the transverse connector 15, in the first position of the accessory holder 1' can adopt a locking position, in which the Access to drive section 7 and connector box 6 of in-row terminal block 3 is blocked (Figure 8). In the position of the accessory element 14, that is, of the transverse connector 15, shown in Figure 9, access is made possible to the drive section 7 and the connector box 6 of the terminal block 3 in a row.

The accessory element 14 may also be a marking element.

Figure 10 shows a schematic perspective view of an arrangement 10 according to the invention with an accessory support 1'' according to a third embodiment. Figure 11 shows the arrangement 10 with the accessory support 1'' with an accessory element 14.

The accessory holder 1'' in the third embodiment is configured as a clamping device 24. The clamping device 24 includes a base 24a and two clamping jaws 24b, 24c.

The base 24a has on its underside the same plug section 23 with clamping projections 23a as the base plate 19a of the clamp element 19. This is not shown, but is easily imagined in relation to Figure 6. In this way, the clamping device 24 can also be mounted on the marking section 8 of the terminal block 3 in a row.

Elastic clamping jaws 24b, 24c projecting upwards are formed on the base 24a. The clamping jaws 24b, 24c are located opposite each other and define between themselves a receptacle 25 for the accessory element 14. Here, the clamping jaw 24b is configured with a thickened end section, which facilitates a separation of the jaws 24b, 24c for fastening when inserting and removing the accessory element 14.

The accessory element 14 here consists of a circuit breaker 26 with a cylindrical body, the shape of which corresponds to the housing 25. Of course, other accessory elements 14 with a different shape can also be used, with the housing 25 being configured corresponding to the respective shape.

In this exemplary embodiment, the first position and the second position of the accessory support 1'' are identical.

Figure 12 represents a schematic perspective view of an arrangement 10 according to the invention of a terminal block 3 in a row with a fourth embodiment of an accessory holder 1''' according to the invention. Figure 13 shows a schematic perspective view of the accessory holder 1'''. Figure 14 shows the accessory holder 1''' according to Figure 13 in a schematic perspective view with an accessory element 14.

Figures 15 to 17 show schematic perspective views of an arrangement 10 according to the invention with the fourth embodiment of the accessory support 1''' according to Figures 13-14 in different positions.

The accessory holder 1''' is a plug housing 27 with a front face VS and a rear face RS and serves to accommodate the accessory element 14, which can be inserted into and removed from the plug housing 27.

The plug housing 27 has a front wall 27a, two side walls 27b, 27c, a front plate 29, a transverse wall 29a and two plug sections 28, which can also be designated as plug legs.

The two side walls 27b, 27c are each mounted at right angles to a short edge of the front wall 27 and are reinforced with each other in the end regions of these connections by the transverse wall 29a on the rear face RS. In this context, the transverse wall 29a is connected with a longitudinal edge at right angles to the front wall 29a. The front plate 29 is joined with the two side walls 27b, 27c at the front face VS, where it is arranged on its longitudinal edges from a central area of the side walls 27b, 27c to its free ends and is firmly joined with the walls sides 27b, 27c.

Three projections 31,32, 33 are arranged on the outer face of the front plate 29 and protrude into a lower area of the front plate 29. The projections 31 and 33 are cubic in shape and are located above the plug sections 28. The central projection 32 is approximately twice as wide as one of the projections 31, 33 and is at the same height as the other projections 31 and 33, but above an intermediate space 34 that is defined between the interior faces 28c of 28 plug sections.

The front wall 29 is located in a plane parallel to the transverse wall 29a. Between a longitudinal edge of the front plate 29, which faces the front wall 27a, and the front wall 27a, an opening is defined as a cutout AS to a receptacle 30 in the socket housing 27. The housing 30 is surrounded by the front wall 29a and the side walls 27b, 27c in the shape of a C. Furthermore, the housing 30 is covered on the front face approximately half with the face plate 29 and on the rear face approximately up to a room with the transverse wall 29a. The housing 30 is open downwards, as can be clearly seen in Figure 14 and Figure 17.

The plug sections 28 have an essentially U-shaped cross section, which is formed by respective front faces 28a, outer faces 28b and inner faces 28c, and which is open towards the rear face up to the end sections 28d and their contact areas. Union. Thus, the U-shaped cross section defines elongated housings 30a.

The plug sections 28 are each arranged in a corner area on the underside of the plug housing 27 and are each connected to the front plate 29 and to the side walls 27b, 27c. In this context, the front faces 28a are aligned with the front plate 29. The outer faces 28b extend the side walls 27b and 27c through an undesignated gradation. The inner faces 28c each have extensions 28e that extend into the housing 30 and are fixed to the inner face of the front plate 29. In this way, the housings 30a of the plug sections 28 are connected to the housing. 30 housing 27 plug.

Between the extensions 28e, a bridge 29 parallel to them with the same shape as the extensions 28e is arranged centrally. The extensions 28e and the bridge 29 are arranged with the same distances from each other, which correspond to the dimensions of the plug tabs 18a, 18b of the transverse connector 15, and thus form guides for the plug tabs 18a, 18b of the connector transversal 15 when it is inserted in the housing 30.

Figure 14 illustrates a process of inserting or removing the transverse connector 15 into or from the plug housing 27. The transverse connector 15 is inserted with the clamping section 17 from the front into the receptacle 30 from the rear face RS of the plug holder 27 in such a way that the clamping section passes through the cutout AS. Then, the transverse connector 15 is rotated in the housing 30 towards the socket housing 27 (rotating movement SB) in such a way that the clamping section 17 rests on the transverse wall 29a, the housing 16 of the transverse connector 15 comes into contact with the inner face of the face plate 29 and the outer plug tabs 18a are inserted into the housings 30a of the plug sections 28 and the inner plug tabs 18b are arranged in the intermediate space 34 between the plug sections 28.

The withdrawal process takes place in reverse.

When the transverse connector 15 is inserted into the plug housing 27, its two outer plug tabs 18a are each arranged in one of the plug sections 28. The plug sections 28 are approximately one and a half times longer than the cross connector plug tabs 18b housed therein. In this way, the two central or inner plug tabs 18b protrude into the intermediate space 34 by a length corresponding to only half the length of the plug sections 28 (Figure 12).

Figure 15 shows a first position of the accessory support 1'' with the transverse connector 15 inserted. The accessory holder 1''' is inserted as a plug housing 27 in this first position in the connector box 6 of the in-row terminal block 3, the two plug sections 28 engaging in the outer row terminals 2.1 and 2.4. In this context, the projections 31, 32, 33 are located on the actuators of the drive section 7 and block them. Since the length of the plug tabs 18a, 18b on the plug housing 27 is shortened relative to the mounting position of the plug housing 27 on the connector housing 6 due to the above-described mounting position of the transverse connector 15 in the plug housing 27, in this first position no electrical connection of the transverse connector 15 with the contacts in the connector housing 6 takes place.

In Figure 16, a second position of the accessory support 1'' is represented. The transverse connector 15 is taken out of the plug housing 27 and inserted into the connector box 6 of the in-row terminal block 3 for electrical connection of the terminal contacts. The accessory holder 1''' in its second position is inserted with a plug section 28 into the opening 5 of the terminal 2.4 in the outer row.

Figure 17 shows a variant of the second position of the accessory support 1'''. In this context, the accessory support 1''' is inserted with its outer projections 33 into the opening 5 of the terminal 2.4 in the outer row.

The projections 31,32 and the ends of the plug sections 28 each correspond to the shape of the opening 5.

In the second two positions, access to the connector box 6 and the drive section 7 is possible.

The invention is not limited by the exemplary embodiment described above, but can be modified within the scope of the claims.

For example, it is conceivable that in the embodiments according to Figures 4-5, Figure 8 and Figure 15 an additional clamp element 19 may be mounted on the marking section 8, for example to hold a marking. The clamping device 24 with the circuit breaker 26 could also be additionally mounted here.
