Definitions
- the present invention has for its object to provide branching devices for electrical lines, with which line branches are in particular easier to install or to install than conventional branching devices.
- a line branching can be installed quickly, inexpensively and safely.
- the outer insulation of the cable only has to be removed before the strands individually from above be pressed into the through-channel in their respective strand clamp.
- the contact lips cut through the insulation of the strands with their cutting edges and thus establish an electrical contact between the strand and the strand clamp.
- the strands therefore no longer have to be cut off in the region of the branch according to the invention and re-installed at their ends. It is no longer the case that the strands in the branching device become too short.
- only the insulation of the stranded wire is cut through, while its conductive core runs uninterruptedly through the through-channel. This maintains the tensile strength of the strand, which means an enormous gain in safety.
- the through-channel runs in a straight line through the wire clamp.
- the material stress for the strand is lowest since it does not have to be stretched or only very slightly.
- the wire clamps are advantageously detachably received in the holder in the housing. This means that they can be easily replaced, for example, to use a different type of wire terminal block with a wider or narrower through-channel.
- At least one of the contact lips is preferably flexible in a direction directed away from the through-channel, so that it allows the through-channel to be widened. This means that it can adapt to the diameter of the conductive core of the strand and clamp it in the through-channel due to its restoring force.
- a catch can be provided between the wire clamp and its holder.
- the wire clamp can be attached to the bracket before the branch is installed again. This is particularly advantageous if the junction box is to be installed upside down and the stranded wire terminals could otherwise fall out of its holder.
- the bracket for the stranded wire clamps in such a way that it is detachably attached to the housing. This means that the holder can be replaced, for example if wire clamps are required for another type of wire.
- Such a branching device is particularly easy to install, in which a common holder is provided for all stranded wire terminals. All stranded wire clamps can be removed or inserted in their common holder at once.
- At least one hold-down device is provided for the strands, which holds the strands in the through-channels of the strand clamps. After the branch has been installed, the hold-down device prevents the strands from unintentionally coming loose from the through-channels and thus interrupting the electrical contact.
- At least one common hold-down is provided for all strands. After inserting the strands into the through-channels of the strand clamps, all strands of the electrical cable can be attached at once. This simplifies the assembly of the branch.
- the hold-down device or hold-down devices could, for example, be designed such that they represent a closure of the openings formed between the contact lips. The insertion of the hold-down device thus closes in particular the through-channels, so that the strands can no longer detach from the through-channels.
- the hold-down device or hold-down devices can preferably be locked with the holder of the stranded wire clamps. Should the cable ever have to be replaced, the hold-down device and the holder of the wire clamps can be quickly replaced together. In addition, when the branch device is installed, the hold-down device is attached to the housing.
- the one or more hold-down devices can also be latched directly to the housing. It has proven to be expedient if the holding-down device has a transverse plate which closes off the through-channels and has openings through which the connecting lugs of the stranded wire terminals protrude. The cross plate thus creates a separation between the area of the through-channels and the area of the connection lugs and ensures that the branched cables are mounted at the intended locations on the stranded wire clamp.
- seals are provided on the housing at the outputs for the line. Particularly in dirty or damp environments, the seals prevent foreign particles from entering the branching device, which could have impaired their operation.
- the seals can be designed, for example, as sealing rings with a lateral incision for inserting the line. As one-piece elements, such sealing rings are particularly easy to install.
- the housing of the branching device can preferably be assembled from a lower housing part and an upper housing part.
- the strands can first be accommodated in the strand terminals provided in the lower housing part before the upper housing part is finally put on as a protective cap.
- FIG. 1 shows a perspective view of a first exemplary embodiment of a branching device according to the invention
- FIG. 3 shows a perspective view of a wire clamp which can be used in the branching device according to the invention
- FIG. 4 shows a partially sectioned top view of the wire clamp with the wire inserted
- Figure 5 is a perspective view of a bracket of the wire clamps
- FIG. 1 shows a first exemplary embodiment of a branching device 1 according to the invention. It has a housing 2 which can be assembled from a lower housing part 3 and an upper housing part 4.
- the two housing parts 3, 4 can be molded from a plastic, for example by injection molding.
- the two housing parts 3, 4 have an approximately rectangular cross section.
- the upper housing part 4 can be screwed to the lower housing part 3.
- through openings 6 are provided on lateral shoulders 5 at each of the four corners of the upper housing part 4.
- these openings 6 are aligned with holes 7 in the lower housing part 3. In these holes 7 there are internal threads into which a screw passed through the openings 6 can engage.
- semicircular recesses 8 are provided both on the lower housing part 3 and on the upper housing part 4.
- the cutouts 8 are arranged such that circular openings 9 result when the housing is assembled. These are the outputs 9, through which a line (not shown) is led out of the housing 2 or into this.
- each bracket 10 defines an octagonal receiving space 12, into which a wire clamp 11 can be inserted from above.
- the receiving space 12 is delimited by two side walls 13, each of which has an approximately U-shaped cross section.
- the walls 13 of the holder 10 are arranged in such a way that a straight-line through-channel is created between them, which is essentially parallel to the longitudinal axis of the housing 2.
- latching elements not shown in the holder, into which latches 14 can be snapped onto the stranded terminals 11. In this way, the wire clamp 11 can be detachably held in the holder 10.
- the branching device 1 is shown in a state in which two wire clamps 11 are inserted into two of the holders 10. Terminal lugs 15 on the wire terminals 11 protrude beyond the top of the brackets 10.
- the shape of the connecting lugs 15 as such is known. They have a through hole 16 in the middle through which a strand to be branched can be passed.
- a third wire clamp 11 is shown outside of its holder 10. The exact shape and mode of operation of the wire clamps 11 will be described with reference to FIGS. 3 and 4.
- a hold-down device 17 can also be seen in FIG. 1. Its length corresponds approximately to the inner width of the lower housing part 3.
- the hold-down device 17 has a transverse plate 18 which, after the hold-down device 17 has been inserted, runs parallel to the bottom of the lower housing part 3 on the upper edges of the holders 10 rests. Elongated openings (not shown) are provided in the transverse plate 18, through which the connecting lugs 15 of the stranded wire clamps 11 can protrude.
- two recesses 23 are provided in the top of the upper housing part 4. They each serve to receive the end of a line to be branched, the strands of which can be guided through openings in the bottom of the recess 23 into the interior of the housing 2, in order to be connected there to the connection contacts designed as connection lugs 15.
- the depressions 23 have a hexagonal cross section.
- the branching device 25 could also be designed such that corresponding connector plugs for the branched line with a hexagonal outer shape can be inserted into the hexagonal recesses 23.
- FIG. 2 shows a second exemplary embodiment of a branching device 25 according to the invention. Parts which correspond to those of the branching device 1 have been given the same reference symbols.
- a common holder 26 is provided for all three wire terminals 11 in the branching device 25.
- This bracket 26 is shown separately with reference to Figure 5.
- the holder 26 consists of a one-piece part made of an insulating material, for example plastic. It has a base plate 27, from the upper side of which walls 28 protrude at right angles, each of which forms a receiving space 12 for a wire clamp 11 between them in pairs.
- the walls 28 are shaped and arranged in such a way that the receiving space 12 formed between them can receive an essentially octagonal strand clamp 11.
- strain relief is provided in the branching device 25 at each outlet 9 from the housing 2.
- This strain relief includes semi-circular clamping pieces 36 made of a hard plastic, which are inserted into each recess 8 on the lower housing part 3 or upper housing part 4. Wings 37 protrude laterally from the clamping pieces 36.
- An adjusting screw 38 is assigned to at least one of the paired clamping pieces 36. It is accessible from the outside of the housing 2, in the exemplary embodiment shown from the outside of the upper housing part 4.
- the narrowest point of the through-channel 47 is determined by the two parallel edges 48. Since these edges 48 protrude pointedly into the through channel 47, they provide cutting edges for a strand to be inserted into the through channel 47 In an upper section of the contact lips 46, the distance between them widens toward an insertion side of the through-channel 47. In this area, the paired contact lips 46 form an insertion section 49, which guides the stranded wire into the through-channel 47 when it is inserted.
- FIG. 4 shows a strand clamp 11 with a strand 50 inserted into it.
- This has a conductive metal core 51 and insulation 52 made of a soft plastic.
- the strand 50 has been pressed into the through channel 47 from above via the insertion section 49.
- On the left-hand side it is shown in section that the contact lips 44, 46 with their cutting edges 48 both cut through the insulation 52 and also cut into the conductive core 51 of the strand 50, since the distance between the cutting edges 48 is smaller than that The diameter of the metal core 51 is. In this way, electrical contact was made between the metal core 51 and the wire clamp 11.
- the number of branched lines does not have to be two either.
- a single branched line could equally well be created, or the possibility for three or more branched lines could also be provided.
- branching devices are conceivable in which branching from more than one electrical line takes place parallel to one another.
- the combination nmk with n incoming electrical lines, each with m strands, and k branched electrical lines is almost arbitrary.
- Separate housing outputs 9, sealing rings 21 and strain reliefs with terminals 36 would then preferably be provided for each of the n electrical lines.
- more or fewer connecting lugs 15 can also be provided per wire terminal 11.
