Description

Electrical connection distributor, carrier for a connection distributor and use of a multipolar electrical plug connector

Technical Field

The invention relates to an electrical connection distributor having a plurality of electrical connection points, which are each designed for connecting an electrical conductor or a plurality of electrical conductors. The invention also relates to a carrier device of such a connection distributor and to the use of a multipolar electrical plug connector for forming a plurality of connection locations of an electrical connection distributor.

Background

A wiring organizer is a power distributor used for wiring purposes in an electrical distribution device. In this case, it is desirable for such a connection distributor to have a plurality of electrical connection points, to which individual electrical lines are connected as simply as possible and can also be released again if necessary. In this case, the electrical lines to which a particular group is connected should be electrically connected to one another. While no electrical connection between the respective groups of connected electrical conductors is desired or should be established only as required.

The wiring distributor is arranged to: an electrical interface can be formed between the electrical installation device and the surrounding environment. Accordingly, the connector distributor is usually inserted into a recess or opening in the wall of the housing, for example in a recess or opening in the rear wall of the housing, in a switchgear cabinet or in another electrical installation device. A wiring organizer forming an interface then connects the electrical components within the housing with electrical components located in the ambient environment outside the housing, such as actuators and/or sensors. Such wiring harnesses are used, for example, in railway technology, for example for controlling switches and signals. In contrast to the terminal block, the connection distributor is therefore also not designed for mounting on a support rail, for example a push-on rail, and accordingly does not have such a fastening element for mounting on the support rail.

Since, depending on the application, different sizes of wiring organizers are required, i.e. wiring organizers with more or fewer connection locations, the following proposals have been made in the prior art: such a terminal block distributor can be assembled modularly by means of individual terminal block modules (Rangierwaben), as is known, for example, from DE 102015105545 a1 or DE 19512226 a 1.

Disclosure of Invention

The invention is based on the object of improving such an electrical wiring organizer in terms of cost and functionality.

This object is achieved in the electrical connection distributor mentioned at the outset as follows: a plurality of or all the connection locations are formed by wire connection contacts of a multipolar electrical connector which is plugged into plugging locations of a carrier device of the wiring organizer.

It has been recognized that such a wiring organizer formed from individual patch panel modules, as described in the prior art, while having many advantages in terms of modularity, are relatively high in terms of manufacturing expense and production costs of the individual patch panel modules. In contrast to the known designs of electrical wiring organizers, another approach is taken in the present invention, which is: a multipolar electrical connector is used to form the connection location of the electrical wiring organizer. In this case, any electrical plug connector can be used in principle, in particular existing, commercially available plug connectors can be used, so that, for example, by using plug connectors which have already been produced in large numbers, a cost-optimized effect of the electrical connection distributor can be achieved.

Since the connection points of the connection distributor are formed by such an electrical plug connector or its wire connection contacts, the following possibilities are provided as positive additional effects: after the mass production of the electrical connection distributor, i.e. after the required electrical lines have been connected to the connection locations, one, more or all of the plug connectors can be temporarily removed and reinserted at any time, for example to carry out specific maintenance work on the electrical installation with the electrical connection distributor.

By means of the invention, a very high connection density is achieved compared to the prior art, and therefore advantages in terms of the installation space required for the electrical connection distributor are achieved.

In principle, any multi-pole electrical plug connector can be used for implementing the invention, wherein the electrical plug connector used on the carrier of the wiring distributor can be a similar plug connector or a differently designed plug connector, for example a male and female plug connector or a connector of a different plug system or a plug connector with a different contact pitch. The plug connectors can also be of identical or different design with regard to the design of the wire connection contacts for connecting electrical lines. Plug connectors with wire connection contacts in the form of winding terminals, screw terminals or spring force clamping terminals can be used. It is particularly advantageous to use plug connectors with spring-force clamping terminals as the wire connection contacts, since this enables a quick contact and also a quick release of the electrical wires. Furthermore, a reliable electrical contact is permanently provided by the spring action.

In particular, a plurality of or all connection locations of the connection distributor can be formed by wire connection contacts of a multipolar electrical plug connector which is designed as a spring force clamping terminal. In the case of spring-force clamping terminals, the clamping of the individual electrical conductors is effected by means of a clamping spring, in particular by means of a clamping edge of the clamping spring. The electrical line can be pressed or pulled against a further contact element, for example a busbar, by means of the clamping edge. Such a spring-force clamping terminal can furthermore have an operating possibility for a manual operation of the clamping spring, via which the clamping spring can be deflected and the clamping edge can be released from the electrical conductor, so that the electrical conductor can be removed from the spring-force clamping terminal or introduced into it without difficulty. As an operating possibility, for example, an operating opening in the housing of the plug connector, an operating button provided on the plug connector, or a lever provided on the plug connector can be present. If only the operating opening is present, manual operation can be carried out by means of a separate tool, for example a screwdriver.

The clamping spring can in particular have a clamping leg, on the free end of which the mentioned clamping edge is formed. The busbar can have a raised ridge. A clamping point can then be formed between the clamping edge and the bulge of the busbar, at which clamping point the electrical conductor is clamped at the spring force clamping terminal.

The clamping spring can have a spring bow connected to the clamping leg and an abutment leg adjoining the spring bow. Via the contact legs, the clamping spring can be supported in the plug connector, for example on a housing of the plug connector, on the busbar or on a component coupled to the busbar. The contact leg of the clamping spring has only a supporting function and no electrical function.

The electrical plug connectors used can also be identical or different in terms of their pole count. Particularly advantageous are electrical plug connectors with a pole count in the range from 2 to 10, for example three-pole plug connectors.

The good manufacturability and low production cost of the electrical wiring organizer according to the invention can also be promoted in the following way: providing a difference from the maximum modularity proposed in the prior art honeycomb concept (Waben-Konzept). This is achieved as follows: in addition to the electrical plug connector as a central component, the electrical connection distributor also has a carrier device with a plugging position for plugging the electrical plug connector. At the respective plugging positions, a mating plug connector for the electrical plug connector to be plugged is formed. Such a carrier device can be produced very simply and at low cost, for example by means of a carrier member which can be made of plastic and which has electrical plug contact elements fixed thereon, by means of which a mating plug connector for an electrical plug connector to be plugged is formed. Such a carrier device can also be constructed on the basis of a modular principle, wherein in this case the modularity advantageously does not point in the plane of the honeycomb, but rather a carrier device is provided which has, for example, at least 4 or at least 8 plug positions for plugging the electrical plug connector. This carrier device can then be modularly combined with other carrier devices to assemble an enlarged wiring organizer that is sized as desired.

According to an advantageous further development of the invention, it is provided that one, several or all plug connectors are each associated with at least one contact bridge for electrically bridging several or all wire connection contacts of the respective plug connector. In this way, the electrical transverse connection to be provided is provided in the electrical connection distributor meaningfully between the individual connection points and, correspondingly, between the electrical lines connected to the connection points. The contact bridge can be designed as a relatively simple component, for example as a simple metal sheet which is inserted onto the respective plug contact element of the respective plug position of the carrier.

According to an advantageous further development of the invention, it is provided that the contact bridges associated with the respective plug connector are fixed to the plug connector and/or to a plug-in position of the carrier device associated with the plug connector. This allows for a maximum degree of flexibility in making electrical lateral connections between the wire bond contacts. Depending on the plugging position, the contact bridge is fixed to the plug connector in the plug connector and to the carrier in the other plug connector. It is also possible that the contact bridges of the plug-in position can be arranged on the plug connector and additionally, for the same plug-in position, the contact bridges can be arranged on the carrier. The short-circuit bridges present on the plug connector can then remain even when the plug connector is removed, while short-circuit bridges remain via the contact bridges on the carrier for oppositely disposed plug positions.

According to an advantageous further development of the invention, it is provided that the carrier device has a plurality of plug-in positions arranged in a matrix for plugging in the multi-terminal plug connector. In this way, a single carrier device can already be used to form the electrical wiring organizer. The carrier device can, for example, be seen from one side and has 2x 2 plug positions or 3x 3 plug positions. However, the number of vertically extending rows of the plugging position does not necessarily have to be the same as the number of horizontally extending rows of the plugging position.

According to an advantageous development of the invention, it is provided that the plug-in position can be arranged on one side of the carrier or on two opposite sides of the carrier. If the carrier device has a plug-in position on only one side, it can be used, for example, advantageously for the following applications: wherein on the rear side there is a wall or a closed housing. If the carrier device has plug-in positions on two opposite sides (sword-shaped), the number of possible plug-in positions of the carrier device is doubled in a simple manner. Furthermore, an electrical connection between two opposite plug-in positions can already be provided by the plug-in contact elements passing from one side to the opposite side. If the carrier device has plug-in locations on only one side, bridging between the plug-in contact elements at the plug-in locations can also be provided as follows: with a U-shaped bent connecting pin, which protrudes towards one side of the carrier.

According to an advantageous further development of the invention, it is provided that the carrier device has, at one, several or all plug-in positions, corresponding latching elements for latching a plug connector plugged onto the plug-in positions. In this way, the electrical plug connector can be fixed on the carrier in a simple and reliable manner and is fixed against slipping off. The latching elements of the carrier are designed here as counter-parts to the latching elements of the plug connector, for example in the form of latching lugs and, as counter-parts to the latching lugs, in the form of latching depressions or latching edges. The latching element can be a component of a locking element which is either firmly connected to the carrier or formed integrally therewith, or which is formed as a separate component and can be plugged onto the carrier.

Alternatively, the fixing of the plug connector at the plugging position can also be carried out by other conventional fixing methods, for example screwing, gluing, riveting.

According to an advantageous further development of the invention, it is provided that the carrier device has a coupling element, via which the carrier device can be combined with a further carrier device or a plurality of further carrier devices to form an enlarged connection distributor. In this way, the carrier device can be used as a module for an enlarged patch distributor device. The individual support devices can be connected to one another reliably with little effort by means of coupling elements, for example in the form of tongue/groove connections.

According to an advantageous development of the invention, it is proposed that a bridge connection contact (bronischrusskontakte) is present at one, a plurality of or all of the plug-in positions in order to establish an electrical connection between two or more adjacent plug-in positions and a plug connector plugged thereon via a bridge (broncker) which is plugged onto the bridge connection contact. This makes it possible in a simple manner to provide groups of connected electrical lines electrically connected to one another at a plurality of plug locations. Since the bridge is pluggable, it can also be removed again, so that a bridge can be established between the plugging locations as required, and can be cancelled again. By providing such bridging possibilities between plug locations, a particularly high packing density of the electrical connection distributor can also be achieved.

According to an advantageous further development of the invention, it is provided that the carrier device has, at one, several or all plugging locations, corresponding first plug contact elements which are designed as mating plug connectors of second plug contact elements of the plug connector to be plugged into the plugging location. In this case, one plug contact element (of the carrier or of the plug connector) is designed as a contact pin, while the other plug contact element is designed as a counterpart thereto, for example as a contact bush or fork contact. The first plug contact element of the carrier device can already be integrated into it or fixed to it on the production side, for example in such a way that: the first plug contact element is injection molded in a plastic injection molding process, in which the carrier device or its carrier component is produced, so that it is at least partially embedded in a plastic material.

According to an advantageous further development of the invention, the carrier device has at least one contact bridge at one, several or all plug-in positions in each case for electrically bridging several or all first plug contact elements of the respective plug-in position. Accordingly, the aforementioned contact bridge is part of the carrier device.

According to an advantageous further development of the invention, it is provided that the contact bridge also has a bridge connection contact for the plug-in bridge at one, a plurality of or all plug-in positions. This has the following advantages: the contact bridge and the bridge can be provided in a particularly simple and cost-effective manner, for example in that: they are formed in one piece as sheet metal parts. The mounting of the carrier device is thereby also simplified.

According to an advantageous further development of the invention, it is provided that one, several or all of the plug connectors are designed as circuit board plug connectors. In this way, the connection distributor can be realized particularly cost-effectively and space-effectively, since such a circuit board plug connector can be obtained cost-effectively and in small dimensions. A high packing density of the connection locations of the connection distributor can thus be achieved.

According to an advantageous further development of the invention, it is provided that the carrier device has a substantially flat and/or planar carrier member, which has an intermediate wall or rear wall in which the plug contact elements are held. The carrier member with the intermediate wall and the rear wall thus serves as a fastening for the plug contact element. In accordance with a configuration of the carrier with a plug-in position provided only on one side of the carrier or on two opposite sides of the carrier, the plug-in contact element can project beyond the intermediate wall or the rear wall only on one side or beyond the intermediate wall or the rear wall on two opposite sides. The plug contact element can in this case project in particular substantially perpendicularly to the intermediate wall or the rear wall.

According to an advantageous development of the invention, it is provided that a plurality of or all plug-in positions are separated from one another by a horizontal wall and a vertical wall of the support device. This allows the plug connectors to be simply distributed and plugged to the plugging locations by the user. This prevents a reverse plug-in. The horizontal wall and the vertical wall can be separate components or part of the previously described load-bearing member, for example in the manner: the horizontal and/or vertical walls are molded onto the intermediate or rear wall of the carrier, for example in a plastic manufacturing process.

The object mentioned at the outset is also achieved by a carrier device of a connection organizer of the type set forth above, having a carrier member on which a plurality of plugging locations are present for plugging a respective multi-pole electrical plug connector at the plugging locations. The advantages set forth above can thus also be achieved. The carrier device or its carrier member can be improved in particular by the features set forth above.

The object mentioned at the outset is also achieved by the use of a multipolar electrical plug connector for forming a plurality of connection locations of an electrical connection distributor. The advantages set forth above can thus also be achieved. The electrical plug connector can be of the type described above. The plug connector can in particular have spring-force clamping terminals for connecting electrical lines, which serve as connection points for the connection distributor. In this way, an advantageous spring-clamping connection technique can be used in the electrical wiring organizer.

Fig. 1 shows a first embodiment of the electrical connection distributor, in which a plurality of plug-in points 20 for plugging in the multi-pole electrical plug connector 3 are respectively present in a matrix on two opposite sides on the carrier 2. In this case, there are 4 × 4 docking locations 20 on the front side of the carrier, which is obliquely recognizable from the front. On the opposite rear side, there can likewise be 4 × 4 plug locations 20. The connection points 6 of the connection distributor are provided by the respective poles of the corresponding plug connector 3. The same number of connection points 6 as the poles of the plug connector 3 and as many plug connectors 3 are provided. Thus, in the example of the three-pole plug connector 3 shown, three connection locations 6 are thus provided for each plug connector 3. The connection locations 6 can be accessed via the conductor insertion openings 30 in the housing 39 of the respective plug connector 3. The plug-in connector 3 is plugged with its plugging side, i.e. the plugging surface 35, from the front onto the corresponding plugging position 20 of the carrier 2. The carrier device 2 has for this purpose a carrier member 29, which is explained in more detail below according to further examples.

For better overview, fig. 2 shows a smaller wiring organizer 1, which has only 2 × 2 plug locations 20 on each side of the carrier member 29. The carrier element 29 has a middle or rear wall 23, which in the illustration in fig. 2 extends vertically and forms a partition wall, by means of which the front side, which is visible in fig. 2, is separated from the (opposite) rear side located at the rear. On each side of the intermediate or rear wall 23, the respective plug locations 20 are separated from each other by intersecting vertical and horizontal walls 21, 22. The carrier element 29 with the vertical wall 21, the horizontal wall 22 and the intermediate or rear wall 23 can be produced, for example, in one piece as a plastic injection-molded element.

The carrier device 2 has further elements at each plugging position 20, which will be explained in more detail below with reference to fig. 3, since they are largely covered in fig. 2 by the plugged plug connector 3. Only the bridge connection contact 40 can be identified here.

In addition to the conductor insertion openings 30, the plug connectors 3 can have further openings in their respective housings 39, for example an operating opening 36, through which the respective spring force clamping terminals can be operated with a tool, and a test opening 37, in which operating buttons for the respective spring force clamping terminals are provided, through which test contacts can be inserted in each case.

It can also be seen in fig. 2 that the plug connector 3 can be mechanically fixed by the latching members 24 at the respective plugging position 20, which is the case in the two plugging positions shown on the left. The two plug-in positions shown on the right do not show the blocking member 24.

As can be seen in fig. 3, at each plugging position 20 there is a corresponding first plug-in contact element 4 of the carrier 2, which forms a mating plug-in connector with respect to the plug-in connector 3, in a number corresponding to the number of poles of the corresponding plug-in connector 3, in this case 3. The first plug contact element 4 is in this case designed as a contact pin.

The first plug-in contact elements 4 are not electrically connected first. In order to establish an electrical connection between the first plug-in contact elements 4, the contact bridges 41 are plugged onto one, several or all plug-in locations 20. The bridge connection contacts 40 are molded in one piece onto the contact bridge 41 on the left and right sides, respectively.

The locking member 24 and its corresponding latching element 25 can be identified at the two plug-in positions 20 shown on the left. The corresponding plug connector 3, which can have, for example, latching lugs at corresponding points, can latch onto the latching elements 25 and thus be fixed at the plug-in point 20.

The blocking member 24 is not present in the two plugging positions 20 shown on the right. In this case, it is possible to identify a corresponding fastening element 26 at the plug-in position 20, via which the blocking member 24 can be fastened. In this way, the carrier device 2 can be selectively fitted with or without the latching members 24, or, if different types of plug connectors 3 are to be used, different latching members 24 can also be fitted depending on the plugging position 20.

Fig. 4 shows the two upper plug-in positions 20 of the device according to fig. 3 in a front view. As can be discerned, two sections a-a and B-B are defined therein.

Fig. 5 shows a section a-a of the carrier device 2, so that the elements already explained with reference to fig. 3 can be identified in a side view or a sectional view. It is to be recognized that the latching element 25 can be embodied, for example, as a depression or through-hole in the locking element 24. It can also be recognized in fig. 5 that the first plug contact element 4 is embedded together with the fixing region 42 in the material of the carrier member 29.

Fig. 6 shows the arrangement of the carrier device 2 in the section B-B, so that essentially the same elements as in fig. 5 can be identified, but without the blocking member 24.

The contact bridge 41 can be formed with the bridge connection contact 40 as a one-piece metal component, for example as a contact piece. Fig. 7 and 8 show examples of possible embodiments of such contact strips. In contrast to fig. 7, in the embodiment of fig. 8, a plug-in opening 44 is present on the bridge connection contact 40 for inserting the bridge plug-in contact 51. In both fig. 7 and 8, the plug-in opening 43 of the contact bridge 41 can be recognized, by means of which the contact bridge 41 is plugged onto the first plug-in contact element 4. The number of plug openings 43 on the contact bridge 41 can be different from the number of plug contacts 4 at the plug position 20, so that, depending on the embodiment, only two of, for example, three plug contacts 4 can be electrically connected to one another with the contact bridge 41.

Fig. 9 shows the use of the bridge 5 in combination with the two contact pads of fig. 8. The bridge 5 is inserted with its respective bridge plug contact 51 into the respective plug openings 44 of the two contact strips. Inside the housing 50 of the bridge 5, an electrical connection is established between the two bridge plug contacts 51. The housing 50 serves for electrical insulation and at the same time as an operating aid when plugging or unplugging the bridge 5.

Fig. 10 to 14 show different embodiments of the bridge 5. Fig. 10 shows a narrow bridge 5 with two bridge plug contacts 51 (single bridge), and fig. 11 shows a slightly wider bridge 5 with two bridge plug contacts 51 as well (single bridge). Fig. 12 shows the bridge 5 as a multi-bridge having four bridge plug contacts 51, wherein in the housing 50 all four bridge plug contacts 51 are electrically connected to one another. Fig. 13 shows a further form of bridge 5 (single bridge) with two bridge plug contacts 51, wherein the bridge plug contacts 51 are relatively wide and flat compared to the embodiments of fig. 10 and 11 and have contact projections 52 on the end sides on the inner sides facing each other.

Fig. 14 shows a bridge 5 (multi-bridge) which has an arrangement of bridge plug contacts 51, which corresponds to the embodiment of fig. 13, in each case in double. The four bridge plug contacts 51 are again electrically connected to each other in the housing 50.

The bridge 5 according to fig. 10 to 12 with the substantially pin-shaped bridge plug contact 51 is particularly suitable for the bridge connection contact 40 of the embodiment of fig. 8, while the bridge 5 according to fig. 13 and 14 is particularly suitable for the bridge connection contact 40 according to fig. 7. Fig. 15 shows the use of a bridge 5 according to fig. 13 in combination with the bridge connection contact 40 of the embodiment of fig. 7 in a sectional view of the carrier member 29.

The described bridge 5 can be used in a multiplicity of ways in order to establish an electrical connection between adjacent plug locations 20 or their contact bridges 41. Fig. 16 shows an exemplary use of the bridge 5 for establishing a transverse connection of the lower two plug locations 20. Fig. 17 shows the use of the bridge 5 for establishing a vertical connection of two left-hand plug locations 20.

If four adjacent plug sites 20 are electrically connected to one another, a multi-bridge connector 5 according to fig. 14 can be used (or in another embodiment a bridge connection contact 40 of a multi-bridge connector 5 according to fig. 12) as shown in fig. 18.

Fig. 19 shows the use of three bridges 5 in the case of a wiring organizer, in which the contact 40 is connected using a bridge according to fig. 8. All four plug sites 20 are electrically connected to each other by the three bridge connectors 5 shown. The electrical connection can alternatively also be realized by plugging in a single multi-bridge connector according to fig. 12.

The use of multiple bridges, as opposed to single bridges, has the following advantages: the connection is simpler and faster to implement and the current distribution between the plug-in locations is improved.

When the carrier device is formed with the coupling element, the carrier devices 2 described with reference to fig. 2 to 19 can also be combined modularly to form enlarged carrier devices and thus enlarged connection wiring organizers 1, as is illustrated by fig. 20. According to fig. 20, three carriers 2 have been connected to one another, to which a fourth carrier 2 can also be coupled. For this purpose, the support device 2 has corresponding coupling and/or connecting elements, for example latching elements, which are not shown in detail.

Fig. 20 exemplarily shows a wiring organizer 1 which can be modularly assembled from a plurality of carrying devices 2.

Fig. 21 shows an exemplary plug connector 3, which plug connector 3 has a plurality of second plug contact elements 34 arranged in the region of a plug surface 35 of the plug connector 3. The second plug contact element 34 is designed as a counterpart with respect to the first plug contact element 4 of the carrier 2, so that the plug connector 3 can be plugged with its plug connector surface 35 from the front onto said first plug contact element 4 at the plugging position 20.

The corresponding second plug contact element 34 of the plug connector 3 is connected via the electrical connection element 32, for example a busbar, to a spring-force clamping terminal on the side of the plug connector 3 facing away from the plug surface 35. The spring-force clamping terminals can each have a clamping spring 33 for clamping an electrical conductor which can be inserted through the respective conductor insertion opening 30 into the housing 39 of the plug connector 3 and can then be connected to the electrical connection element 32 via the respective clamping spring 33. The connection points 6 of the connection distributor 1 according to the invention can each be formed by clamping the terminals with a spring force, which is represented here by the clamping spring 33 together with the respective wire lead-through opening 30.

The wire connection contacts of the multipolar electrical plug connector 3 are shown in a sectional view in fig. 22. It is recognizable that the electrical line 7 is introduced through the line introduction opening 30 and clamped at the clamping location by means of the clamping spring 33. In this embodiment, the clamping spring 33 has an abutment leg 10, a spring bow 11 adjoining the abutment leg 10, and a clamping leg 12 adjoining the spring bow 11, which clamping leg has a clamping edge 13 formed at the free end of the clamping leg 12. The clamping spring 33 is supported in the housing 39 via the abutment leg 10 and is supported there against the clamping force exerted by the clamping leg 12.

The busbar 32 has a projecting bulge 14, against which the electrical conductor 7 is pressed by the clamping leg 12 or its clamping edge 13. Thus, a clamping point is realized between the bulge 14 and the clamping edge 13. The bus bar 32 is fixed with one end in the region 15 of the housing 39.

In this way, a connection space 16 for the electrical conductor 7 is provided between the clamping spring 33 and the busbar 32. Furthermore, a conductor receiving pocket 17 can be formed in the housing 39, which is advantageous in particular during the insertion of an electrical conductor 7 having a plurality of individual wires. Thus, an undesired splitting of the individual wires of the conductor 7 can be prevented.

As can be seen, the first plug contact element 4 of the carrier device 2 can project into the housing 39 and electrically contact the wire connection contacts 32, 33, for example in such a way that: an electrical contact of the first plug contact element 4 with the busbar 32 is established.

Fig. 23 shows an embodiment of the electrical plug connector 3 with wire connection contacts 32, 33, in which again a clamping spring 33 is used, which clamping spring 33 is constructed in a similar manner to that described above with reference to fig. 2. The clamping spring 33 in turn has an abutment leg 10, a spring bow 11 and a clamping leg 12. A clamping edge 13 is formed on the free end of the clamping leg 12. Here, a clamping point is also formed between the clamping edge 13 and the bulge 14 of the busbar 32. Fig. 23 shows the plug connector 3 without the electrical lines connected. The electrical conductor can be introduced through the conductor introduction opening 30 in the conductor introduction direction L and clamped at the clamping point between the clamping edge 13 and the bulge 14.

Whereas fig. 22 illustrates a spring force clamping terminal, in which there is only one actuating opening 36 as an actuating possibility for the clamping spring 33, so that a separate tool is required for manual actuation, in the embodiment of fig. 23 there is an actuating button 64 which can be arranged in the actuating opening 36. The operating button 64 can be manually operated at the operating region 60 facing the outside of the housing 39, for example in the manner: a tool, for example, a screwdriver, is inserted into the operation slit 61 in the operation region 60, and pressure is applied to the operation button 64. By such an operating force, the operating button 64 is deflected toward the clamp spring 33. In this case, the clamping spring 33 has an actuating region 18 provided on the clamping leg 12, which can be embodied, for example, as a recess with respect to the actuating button 63. The actuating button 64 is pressed by means of a loading region 66 against the actuating region 18 of the clamping spring 33. Thus, the clamping leg 12 with the clamping edge 13 is moved forward from the busbar 32, thereby opening the clamping point.

The actuating button 64 can have two opposite edge webs 62 on the side facing the clamping spring 33, between which a recess 68 is formed. The edge webs 62 can laterally overlap the clamping legs 12, i.e. the clamping legs 12 enter the recesses 68 between the edge webs 62. The wire insertion opening 30 can have an insertion funnel 65 toward the clamping point. The intake funnel 65 can be formed at least partially by a projecting lug 67 of the operating button 64.

In this case, the contact leg 10 does not rest directly on the material of the housing 39, but rather on contact surfaces 70, 73, which can be designed, for example, as bent webs of sheet metal that are connected to the busbar 32 or are formed integrally with the busbar 32. Thus, the load on the material of the housing 39 is minimized.

In this case, the second plug contact element 34 of the plug connector 3 can be designed as a fork-shaped contact 71 with two contact tongues 72, between which the pin-shaped first plug contact element 4 of the carrier 2 can be received and in this way electrically contacted.

For the sake of simple assembly, the housing can be designed in multiple parts, for example, with a further housing part, for example, the housing closure 19, which is inserted into the housing 39 in order to form the entire housing of the plug connector 3.

Fig. 24 shows an embodiment of the plug connector 3, in which, as in fig. 23, an operating button 64 with the elements already described is present as an operating option. As described above, a clamping point is formed between the clamping edge 13 and the bulge 14. In this case, the clamping spring 33 has an extended contact leg 10, which extends over the obliquely running region 80 as far as the end section 84. The obliquely extending region 80 can extend, for example, substantially parallel to the clamping leg 12. The obliquely extending region 80 can be supported, for example, on an oblique contact surface 83 of the housing 39 or of the housing closure 19. The free end section 15 can be suspended from the support edge 85 of the housing 39 and fixed there.

The housing closure 19 can be fastened to the housing 39, for example, by means of snap fasteners. The latching fastener can have a latching slot 81 on the housing 39 and a latching projection 82 formed on the housing part 19.

The actuating button 64 can be fixed to the housing 39 by a spring web 69, and can be prevented from falling out, wherein the spring web 69 can be formed on the housing 39.

The first plug contact element 4 of the carrier device 2 can be introduced into the housing 39 through the introduction opening 87 and electrically contacted at the busbar 32.
