EP1764870B1 - Connection system for realising of branchings to continuous conductors - Google Patents

Description

The invention relates to a connection system for the realization of branches on a plurality of continuous electrical conductors.

Such a connection system is from the DE 297 08 222 U1 known. The connection system shown in this document serves as the connection system according to the invention for the realization of branches on a plurality of continuous conductors, without having to cut through the continuous conductor. For this purpose, a plurality of groove-like receptacles is formed on a base plate, in which a flat cable or a plurality of electrical conductors can be inserted parallel to each other. Then, a shell is placed to fix the conductors or the flat cable. In this preassembled unit, which is provided with partitions, then clamp-like body are snapped in a pivoting movement, which are each provided with an insulation-penetrating screw, which is connected via a busbar with two tension spring terminals for connecting branching conductor. In this way, two branches can be realized on each conductor, without having to cut through the continuous conductor.

Connection devices with insulation-penetrating conductors are known for example from US 6,811,430 B1 and the EP 0 271 413 known.

In these connection devices, it is necessary to thread individual conductors through openings which are designed to be completely closed, so that these arrangements are not suitable for contacting cables, which are stripped off in sections, in order to realize these branches.

Also the publication DE 101 63 809 A1 discloses a terminal device with insulation penetrating conductors. In order to ensure a secure contact, this document proposes to rotate the contact element relative to the outer housing.

As prior art are also the WO02 / 11249 A1 , the US 5,637,011 and the DE 297 08 222 called.

It is also known to arrange connection discs on a shaft rotatably mounted on a bottom plate. This configuration has not been proven because the conductors introduce laterally are so that the arrangement is not suitable for mounting on already installed continuous cables.

The invention therefore relies on the generic state of the art and wants to optimize this in terms of their structural design. In this case, a compact design and good handling should be realized.

The solution to this problem is the object of the invention.

The invention solves this problem by the subject matter of claim 1.

Structurally, the arrangement over the prior art is further simplified, as it uses for wiring screwless actuated IDC contacts, especially fork contacts. The module frame is well suited for absorbing the forces, in particular in the wiring. In this case, a pre-assembled unit at the manufacturer is created by the connection module, which absorbs in itself the essential wiring forces, without burdening the bottom plate excessively. This also makes it possible in a simple manner, both the continuous conductor and the branching ladder (at least when using direct plug contacts) simplest to contact. It is not necessary to place individual disks, although each of the conductors remains individually connectable.

For example, the continuous conductors may include the continuous conductors of a flat cable or other cable - e.g. a round cable - whose cable sheath has been removed in the area of the connection system, whereby the continuous conductors in this sheathed area are inserted into the receptacles of the base plate.

For contacting, only the preassembled connection module is to be set up, then the connection disks have to be moved into the contact position and the conductor ends of the branch conductors have to be inserted. In this way, a branch can also be quickly retrofitted to an already installed cable.

In this case, the connection disks and thus in particular also the insulation-penetrating contacts arranged thereon are arranged purely displaceably in the receiving shafts in order to ensure a clearly defined contacting perpendicular to the extension of the conductors. A pivoting movement of the insulation piercing contacts when contacting is advantageously avoided.

The connection disks are preferably assigned actuating devices for moving, in particular shifting, the connection disks in the receiving chambers. In this way, the connection disks are moved as a whole in the module shafts defined, which ensures a large-scale sliding bearing and defined guidance of the IDC contacts when contacting the conductor.

It offers itself to be particularly advantageous if the actuators are designed as Exzentereinrichtungen with eccentric discs, as they allow a high power transmission in a confined space.

Further advantageous embodiments are specified in the subclaims.

Fig. 1 shows a connection system 1 with a bottom plate 2 and a can be placed on this floor or base plate connection module with a module frame 3, in which a plurality of connection discs 4 can be used.

For this purpose, the base frame has a plurality of receiving shafts 6, which are separated from one another by partitions 5, into which one of the connection disks 4 can be inserted (see FIG Fig. 5 ).

If necessary, the module frame could also, not shown here, be made of a plurality of mutually e.g. consist detent connected single frame, each of which would be designed to receive each one of the connection plates (not shown here).

The connection discs 4 have - see Fig. 1 and also Fig. 6 and 7 - In each case a disc-like base body 7 made of insulating plastic.

In each of the main body 7 are each a isolationsdurchdringender first terminal 8 (here a fork contact with overspring 34 - is also conceivable training as a piercing - and at least one or more hereby connected conductively branching terminals 9 ( Fig. 6 ) for connecting at least one branching conductor (the latter not shown here) arranged.

The first terminal 8 is formed as insulation piercing contact - here as a fork contact - (see Fig. 2b ), to which a busbar section 10 abuts includes, where two of the branch connections 9 are arranged here. These branch connections 9 can in principle be used in any connection technique (IDC, Screw, spring, etc.) may be formed. Preferably, tool-free directly connectable compression spring contacts 11 (push-in) are used, are arranged for the insertion openings 12 at the top of the base body 7.
In Fig. 2 a bus bar 55 of the compression spring contact 11 is attached to the busbar section 10, wherein the compression spring 56 is arranged on the busbar section 55.

The further branch connection is formed here as a plug contact 13 in a recess 35 for attaching a connection plug (not shown here). Markers are e.g. can be fixed to the top of the connection discs.

In an here upper, central recess 14 with a rounded base of the base body 7, an actuating device 15 is arranged in each case, with which the connection plates 4 and their base 7 together with the terminals, in particular IDC contacts 8 are displaceable in the base frame, so that the connection Disks 4 are next to the IDC contacts 8 on below the terminal slices arranged conductors 21 are pressed to contact these insulation piercing or to connect. In the illustrated embodiment, these actuators 15 eccentric discs 16. These preferably have an eccentric bearing eye 17.

In the base body 7 slot-like first scenes or slots 18 are further formed in side walls 19 on both sides of the recesses 14, wherein the scenes 18 and the bearing lugs 17 of preferably continuous shafts 37 (FIGS. Fig. 1 ), which in turn preferably extend through the entire module frame 4 and again there pass through openings 36 in the side and intermediate walls of the module frame (see Fig. 1 and 2 ). The slots 18 extend in the direction of actuation or perpendicular to the bottom plate 2, which will be explained in more detail below.

The shafts 37 could also extend over only one module slot each, but the continuous shaft is more optimal for absorbing power. The waves 37 could also be formed by pins which are integrally formed on the eccentric discs (not shown). The screwdriver as a preferred operating tool realizes a lever effect for safe wiring.

As again in Fig. 1 and 2 To recognize, the bottom plate 2 has parallel aligned receptacles 20 (eg five or seven) for the conductors 21 of a partially stripped cable 22, which are each bounded by two relatively short webs 38 and at two opposite ends two supports and brackets 23rd for the unsheathed ends of the cable 22, which also act as strain reliefs or can be formed. These pads and brackets 23 are spaced so far apart that they dictate the length of the area to be stripped. The jacket ends 24 are moved towards each other slightly after stripping, in order to be able to fanned the individual conductors apart into the receptacles 20 (cf. Fig. 1 and 6 ).

The bottom plate is further provided with fixing means 25 for fixing the module frame to the bottom plate after inserting the conductors.

These fixing devices 25 are here designed as four snap-in webs which can be latched snapping on the module frame 3, after it has been placed vertically from above onto the bottom plate 2. Other types of mounting and fixing are also conceivable (eg, it is conceivable rotatably fix the module frame or the whole pre-assembled connection module to the bottom plate and then aufzuschwenken on the bottom plate 2 and only one side to lock (see Fig. 5 ) or it by a screw, a strap or an elastic band or the like. On the bottom plate 2 set (not shown)).

The bottom plate 2 has at least one or more apertures 30 which allow it to be checked that the conductors 21 lie correctly in their receptacles 20.

Although here a round cable 22 is shown, a configuration for flat cable is also feasible.

The function of the arrangement Fig. 1 to 7 is as follows.

First, the cable 22 at which branches are to be installed is stripped in the area between the supports and brackets 23. Then, the conductors 21 are fanned out and placed in the receptacles 20 and the cables 22 are placed or clipped in the unshielded area in the formations 23 ( Fig. 1 ).

If this insertion is complete, the connection module as a whole, so the module frame 3 with the preassembled in him connection discs 4 ( Fig. 1 . Fig. 3 ) are placed on the bottom plate 2 and fastened to the bottom plate 2 ( Fig. 4 ). The connection disks still project upwards out of the module frame 3. Now the eccentric discs 16 are still pivoted with a tool such as a screwdriver 40, which presses the eccentric discs 16 in the recesses 14 and thus the individual connection discs 4 in the module frame 3 down, wherein the below-mentioned IDC contact 8 in the associated Recording inserted conductor 21 contacted (compare Fig. 5 . 6 and 7 ).

The arrangement is clear and simple and safe to handle, with the eccentric arrangement, which is supported on the module frame, particularly high Beschaltungskräfte can be realized.

To provide an abutment for final switching, the eccentric discs 16 are laterally provided with guide pins 32 which engage in horizontally extending second scenes 33. On the outer circumference, they have an actuating opening 42 in order to be able to pivot with a tool such as a screwdriver 40. As an abutment at the end could also be formed above the eccentric disc 16 is a kind of roof section or a housing web (not shown here). When wiring the base of the recess 14, in which the eccentric disc 16 is arranged, serves as an abutment to press the terminal plate 4 together with IDC contact 8 on the conductor 21, which is to be contacted.

A further projection 53 on the eccentric disc 16 is used for engagement in detent holes 54 in the connection disc, to make the loading and the Endschaltungsstellung noticeable and their achievement audible.

Alternatively, it is also conceivable to connect the conductors in groups if, instead of the eccentric disks preferably proposed as an actuating device, an eccentric roller extending over a plurality of connecting disks is used (not shown). However, preference is given to the design with individually connectable connection discs, as it allows a more flexible handling.

It is convenient to the arrangement Fig. 1 to be arranged in an overhead housing, although it can also be used eg for direct mounting in a control cabinet. Such a housing 26 with a cover 27 and several, for example, optionally to be used passage 28 for the cable and openings 28 for outgoing conductors (not visible) is in Fig. 8 ff. represented. In the region of the openings 28 walls 39 may be formed, which are detachable at predetermined breaking lines 41, to meet a variety of installation situations ( Fig. 9 ).

A preferably split seal 47 seals the passages or openings for the cable 22.

Thus, this housing is universally applicable in a variety of installation situations. The outer housing may also be designed to accommodate a plurality of connection systems and modules and, for example, have partitions for this purpose. It is also conceivable to put on a base plate several of the connection modules.

Fig. 10 shows a closing element 43 for insertion, for example, in the housing of Fig. 8 when it is arranged at the free end of the cable 22, which has a number of chambers 44, preferably corresponding to the number of conductors, for inserting the free conductor ends, which are designed such that leakage currents and the like are safely avoided. A ring shoulder 45 serves for fixing in the holder.

An alternative embodiment of a housing 26, which is designed to receive a flat cable instead of a round cable (not shown), shows Fig. 11 , For this purpose, only the seals 47 (preferably formed completely or partially divided) of the outer housing 26 each with a flat opening 48 instead of a round opening 49 for the cable 22 (see Fig. 8 ) Mistake.

If no over-housing 26 is used, a direct mounting of the bottom plate 2 on a plate or the like. In the cabinet conceivable (not shown).

The receptacles 20 for the conductors 21 are each formed here from two webs 38, which are formed so that in them conductors 21 of different diameters can be used.

For example, laterally of the outermost webs 38, other conductors of the cable, where no branches are required to be laid (see Fig. 1 ).

Fig. 12 to 15 each show sections of floor panels 2, the remaining areas are not shown here for the sake of clarity.

To Fig. 12 to 15 the webs 38 of the recordings are each provided with latching hooks 50 for holding or latching the ladder in the recordings.

To Fig. 13 21 separate locking receptacles 51 are provided in extension of the receptacles, which are formed on a web 52 which is inserted into the bottom plate or this is attached. This offers the advantage of being able to produce the latching receptacles 51 from a special resilient material, in particular from a different material than the bottom plate.

A variant of this embodiment shows Fig. 22 in which on both sides of the receptacles 21 separate - spring-ring-like locking receptacles 51 are provided, which are each formed on one of the webs 52. These are in turn inserted into the bottom plate 2. In this way, the conductors can advantageously be fixed on both sides of the contacting region.

The locking receptacles 51 can in turn be made of a special resilient material.

In Fig. 14 are labyrinthine in extension of the receptacles 20 arranged locking webs 64 formed on the bottom plate 2, which also serve the locking of the conductors 21.

15 to 22 show a further connection system 1 with the bottom plate 2 and the can be placed on this floor or base plate connection module with the module frame 3, in which a plurality of the connection plates 4 can be used. The structure of this variant corresponds largely to the structure of the embodiment according to Fig. 1 to 8 , Analogous elements have the same reference numerals.

The connection disks 4 in turn each have a disk-like basic body 7 made of insulating plastic. In each of the base bodies 7, the insulation-penetrating first connection 8 is in turn preferably arranged as a forked contact with overspring 34 and at least one or more branching connections 9 connected thereto for connection of at least one branching conductor.

The first terminal 8 is in turn formed as insulation piercing fork contact (see Fig. 2b ), which is adjoined by the busbar section 10, on which two of the branch connections 9 are arranged here.

The one of the branch connections 9 is in turn here a directly connectable compression spring contact 11 (push-in) used, the busbar 55 is bent directly from the busbar section 10.

The further branch connection is also here as a plug contact 13 in a recess 35 for attaching a corresponding connection plug 65 (FIG. Fig. 26 . 27 ) is formed with a sleeve 66, the after Fig. 27 Also, electrical / electronic components 67 and / or in turn further conductor terminals 68 may have.

The actuators 15 in turn have eccentric discs 16 with the eccentric bearing eye 17. In the main body 7, in turn, the slot-like first scenes or slots 18 are formed in side walls 19 on both sides of the recesses 14, the scenes 18 and the bearing eyes 17 are in turn penetrated by continuous waves 37, which extend through the entire module frame 4 and there again Pass openings 36 in the side and intermediate walls of the module frame (see Fig. 15 and 16 ).

The abutment for limit switching is formed here by two housing webs 57 formed above the eccentric disks 16. When wiring turn the bottom of the recess 14, in which the eccentric disc 16 is arranged, serves as an abutment to press the terminal plate 4 together with IDC contact 8 on the conductor 21, which is to be contacted.

The further projection 53 on the eccentric disc 16 also serves again to engage in the detent holes 54 in the connection disc to make the loading and the Endschaltungsstellung noticeable and their achievement audible.

Again, the bottom plate is again provided with fixing means 25 to secure the module frame to the bottom plate after inserting the ladder.

The fixing devices 25 here comprise two snap-on webs 25 which can be latched on the module frame 3 after it has been swiveled onto the base plate on lugs 58 that realize pivoting bearing function and can be inserted into corresponding recesses in the bottom plate 2 (not visible here). This type of installation is particularly easy and safe.

To fix the unshielded areas of the cable just before or at the sheath ends 24 of the cable 22 fixing means are provided here, which are designed as cable clamps 59 with screws 60.

Other housings with seals 47 for flat or round cables show the Fig. 24 and 25 , These housings are universally applicable in a variety of installation situations. The outer housing may also be designed to accommodate a plurality of connection systems and modules and, for example, have partitions for this purpose. It is also conceivable here to set up on a correspondingly shaped bottom plate several of the connection modules. <B> reference numerals </ b> Connection System 1 baseplate 2 module frame 3 Connecting disks 4 partitions 5 receiving shafts 6 body 7 IDC connection 8th branch terminals 9 Busbar section 10 Spring contacts 11 insertion 12 plug contact 13 recess 14 actuator 15 eccentric 16 bearing eye 17 slots 18 side walls 19 Recordings 20 ladder 21 electric wire 22 Pads and mounts 23 coat ends 24 fixing 25 About housing 26 cover 27 breakthroughs 28 bearing eye 29 breakthroughs 30 spigot 32 scenes 33 by spring 34 recess 35 openings 36 waves 37 Stege 38 walls 39 screwdriver 40 Lines of weakness 41 actuating opening 42 termination element 43 chambers 44 annular shoulder 45 poetry 47 breakthrough 48 breakthrough 49 latch hook 50 locking receivers 51 web 52 head Start 53 detent holes 54 conductor rail 55 compression spring 56 bezels 57 snap webs 58 cable clamps 59 screw 60 Wall plug 61 Rifle 62 approaches 63 detent webs 64 Wall plug 65 Rifle 66 components 67 conductor connections 68
