Description

Conductive profile and plug-in connector

Technical Field

The utility model relates to an electrically conductive section bar, electrically conductive section bar has a plurality of grooves and the electric lead in the groove, the groove sets up side by side, extends and leads to the side at electrically conductive section bar's section bar grafting along electrically conductive section bar's longitudinal direction.

The utility model discloses still relate to a tapping formula plug connector that is used for the plug-in connection to this kind of conductive profile material and contacts the electric lead of conductive profile material, wherein tapping formula plug connector has: a plurality of connection tabs arranged side by side; and electrical contact elements which are each designed with an associated connecting lug for being inserted into a groove of the electrically conductive profile in order to electrically conductively contact an electrical line in the groove.

Background

Such conductive profiles and associated tap connectors are used, for example, for the wiring and connection of lamps.

DE 102008014731 a1 shows a plug connector with contact fingers extending in the plugging direction, which have electrical contact taps for mating with corresponding mating plug contacts of the plug connector. In order to prevent incorrect plugging, the plug connector has locking plates which extend in the transverse direction and in the plugging direction.

DE 102008032192B 3 likewise discloses such a plug connector, in which the locking plate is configured asymmetrically for preventing incorrect plugging.

SUMMERY OF THE UTILITY MODEL

In this respect, the object of the invention is to provide an improved electrically conductive profile and an improved tap-off connector which are simple and compact to manufacture and which provide error-proof plugging.

The object is achieved by means of the electrically conductive profile and the tapping plug connector of the invention. Advantageous embodiments are described below.

The error-proof connection is ensured by means of the conductive profile in the following manner: deeper grooves of the first type have a larger groove width than narrower grooves of the second type. In the mating plug connector, the higher connection pads of the first type are wider, viewed in the direction of the array of connection pads, than the connection pads of the second type which are lower relative thereto.

When the tap connector is plugged onto the electrically conductive profile, the higher lug reaches the plane of the plug-in side of the profile first. The higher webs are wider and do not sink into the narrower grooves. In the case of offset or inclined installation of the tap plug connector, it is therefore ensured that the taller and wider webs can only be inserted into the matching wider grooves of the first type. It is then possible for the lower connecting lug to come into contact with the conductive profile in the end. The lower connecting lug must then be introduced into the associated narrower groove of the conductive profile.

Due to the different groove widths of the grooves of the conductive profiles and the corresponding design of the lugs of the tap plug connector with different lug widths, a secure protection against incorrect plugging is ensured in a very simple construction without additional components in the case of very compact constructions.

The deeper grooves of the first type can be arranged alternately with the shallower grooves of the second type, so that the deeper grooves and the shallower grooves alternate side by side transversely to the longitudinal direction of the conductive profile.

The groove arrangement of the electrically conductive profile can be asymmetrical here. The groove side wall of at least one groove can be wider than the opposite groove side wall of the groove. By means of the asymmetry, an error-proof plug-in is improved.

However, it is also conceivable that the error-protection is ensured only by the asymmetry. Irrespective of whether grooves of different groove widths are provided or not, the electrically conductive profile can therefore also be characterized solely by such an asymmetrical groove arrangement.

The electrical conductor is preferably arranged at the groove bottom of the groove. The groove base is accessible here via a groove opening at the profile plug-in side of the electrically conductive profile. The groove is formed here by a groove bottom, groove side walls connected to the groove bottom, which are spaced apart from one another by a groove width, and a groove opening at the profile plug-in side, which is opposite the groove bottom.

The electrical lines can however also be provided at the groove side walls of the groove. It is entirely conceivable for the groove to have the only electrical line of the groove side wall or to have two electrical lines at the groove side walls lying opposite one another.

A combination is also conceivable in which a plurality of electrical lines are arranged in the groove, wherein one electrical line is arranged on the groove bottom and at least one further electrical line is arranged on the groove side walls.

The electrical lines arranged in the grooves extend in the grooves in the longitudinal direction of the electrically conductive profile in the above-described variant.

The tap plug connector adapted to the conductive profile can be designed such that the lugs of the first, wider type and the lugs of the second, narrower type are arranged alternately next to one another.

The error-proof connection can also be provided by a tap connector in the following manner: the distance of the connecting piece from the adjacent side wall on the first side of the connecting piece is larger than the distance of the connecting piece from the adjacent side wall on the opposite second side of the connecting piece. In this way, the tap-and-socket is constructed asymmetrically.

The adjacent side wall of the lug can be the side wall of the lug arranged next to it or a guide wall of the plug connector of the tap type. Such a guide wall can be, for example, an outer wall of an insulating material housing of a plug-in connector, which in the plugged-in state abuts laterally against the electrically conductive profile.

The electrical contact elements of the plug-in tapping connector can project beyond the height of the respectively associated lug. The respectively associated connecting lug of an electrical contact element is here a connecting lug which dips into the same groove as the associated electrical contact element.

The webs can be interrupted here and accommodate the electrical contact elements between them. It is also conceivable for the electrical contact element to be fixedly or movably inserted into the connecting piece.

The tap plug connector can have terminals for connection with at least one associated electrical clamping element and for clamping an electrical conductor. The electrical device can thereby be simply connected to the tap connector in order to supply the electrical device with electrical power and/or be coupled to a data line for data transmission. Such an electrical appliance can be, for example, a lamp. The tap plug connector can however also be used for feeding electrical energy and/or data into the electrically conductive profile.

Detailed Description

Fig. 1 shows an electrically conductive profile 1 with a tap-off plug connector 2 plugged onto it. The electrically conductive profile 1 is formed by a carrier element 3, which is made of an insulating material, for example plastic. The electrically conductive profile has a plurality of

grooves

4a, 4b arranged next to one another, into which grooves the electrical conductor 5 is inserted. In the exemplary embodiment shown, the electrical lines 5 are located at the groove bottoms 6 of the

grooves

4a, 4 b. For this purpose, the groove base 6 has a depression which is narrower than the groove width of the

respective groove

4a, 4b and which is adapted to the cross section of the electrical conductor 5 to be accommodated. The electrical line 5 is held in the respective

adjacent groove

4a, 4b by a projection 7, which forms a stop for the electrical line 5 and holds it against falling out.

The electrically conductive profile 1 has locking tabs 8 at two outer edges facing each other, by means of which locking tabs the electrically conductive profile 1 can be clamped into the support rail.

The tap plug connector 2 which is matched to the electrically conductive profile 1 has an insulating material housing 9 into which the electrical contact elements 10 are inserted. The insulating material housing 9 has a plurality of connecting lugs 11 which project parallel to one another in the same direction from a common plane 12 of the insulating material housing 9. The electrical contact elements 10 are each arranged in such a web 11 or in alignment with such an associated web 11 and project beyond the respective web 11 at least in the non-contacted state. When the tap plug connector is properly plugged onto the electrically conductive profile 1, the electrical contact element 10 can exert a contact force on the adjacent electrical conductor 5.

It is clear that the tap plug connector 2 has a plurality of lugs 11a of the first type which are higher than a plurality of lugs 11b of the second type. In the illustrated embodiment, the lower webs 11b of the second type are furthermore tapered, i.e. conically converging, towards their free ends. In the illustrated embodiment, the connection tabs 11a of the first type are arranged alternately with the connection tabs 11b of the second type in such a way that the connection tabs 11a of the first type and the connection tabs 11b of the second type alternate with one another in an alignment direction transverse to the longitudinal extension direction of the corresponding conductive profile 1.

It can also be seen that the higher tabs of the first type 11a are wider than the lower tabs of the second type 11 b.

The electrical contact elements 10 arranged next to one another in the direction of alignment are each positioned at the same distance from one another in the direction of alignment, i.e. transversely to the direction of extension of the respective conductive profile 1. The electrical contact elements 10 associated with the tabs 11a of the first type are arranged on a first, higher common plane and the electrical contact elements 10 associated with the tabs 11b of the second type, which are lower, are arranged on a common, second plane offset thereto. Two contact planes are provided in the manner described.

The deeper grooves 4a of the first type of the electrically conductive profile 1 are likewise arranged alternately with the shallower grooves 4b of the second type. The grooves 4a of the first type have a groove width different from the grooves 4b of the second type. The deeper grooves 4a of the first type are wider than the grooves 4b of the second type. The groove widths of the first and

second groove types

4a and 4b are adapted to the groove widths of the associated connecting

webs

11a, 11b of the first and second type, respectively. This ensures that the wider and taller webs 11a of the first type cannot sink into the narrower, shallower grooves 4b of the second type, but lie on the side walls of the conductive profile 1 or on the end sides of the webs of the conductive profile 1 remaining between the

grooves

4a, 4 b. In the embodiment shown, the side walls of at least the first type of groove 4a converge conically in order to form an intake funnel for the wider web 11a in the manner described.

It is also evident that the insulating material housings 9 of the tap plug connectors 2 each have, on the outer sides lying opposite one another, an outer wall 13 which, in the correctly plugged state, adjoins laterally the outer side wall 14 of the electrically conductive profile 1. The tap plug connector 2 is thereby guided in the correct plugged state on the electrically conductive profile 1 and can be fixed by the elasticity of the outer wall 13.

It can also be seen that the insulating material housing 9 of the tap plug connector 2 has a conductor insertion opening 15 at the front side for inserting and clamping an electrical conductor 16. The electrical lines 16 are routed to non-visible terminals in the interior of the plug connector 2 in order to be brought into electrically conductive contact with in each case at least one associated electrical contact element 10 there.

The tap connector 2 can thereby be used for connecting electrical devices or for inputting electrical energy and/or data.

It can also be seen that the cross section of the electrical lines 5 of the electrically conductive profile 1 is different. Thus, the three electrical lines 5 on the right side are provided with a larger cross section than the two remaining electrical lines 5 provided on the left side. The electrical line 5 with the larger cross section is preferably used for transmitting electrical energy, while the two electrical lines 5 with the smaller cross section are primarily intended for data transmission, for example in order to form a data bus.

Fig. 2 shows a perspective partial section of the conductive profile 1 from fig. 1. It can be seen that the conductive profile extends in the longitudinal direction L. The deeper grooves 4a of the first type and the shallower grooves 4b of the second type are arranged alternately side by side transversely to the longitudinal direction L and extend parallel to each other. In the embodiment shown, the side-by-

side troughs

4a, 4b of the first and second type are separated from each other by a common side wall 17.

It becomes clear that the electrical conductors 5 placed in the deeper grooves 4a of the first type run out in a common first plane and that the electrical conductors 5 placed in the shallower grooves 4b of the second type run out in a second plane spaced apart from the first plane.

The

slots

4a, 4b of the first and second type are open on the side opposite the slot bottom with the inserted electrical conductor 5, i.e. on the plugging side, so that a tap plug connector is plugged onto said plugging side and the

webs

11a, 11b with the associated electrical contact elements 10 can be inserted into the

respective slots

4a, 4b of the first and second type.

Fig. 3 shows a front view of the plug connector 2. It becomes clear here that the groups of equally spaced-apart connecting

pieces

11a, 11b of the first type and of the second type, which are arranged alternately side by side, are fitted asymmetrically into the space between the outer walls 13. It can be seen that the outer, right-hand web 11b is arranged at a distance a1 from the right-hand outer wall 13, while a first, higher and wider web 11a is connected to the outer web 11b of the second type at a smaller distance a 2. On the left, the outer connecting webs 11b of the second type are connected to the left outer wall 13 of the tap plug connector 2 at a distance a2, which distance a2 is smaller than the distance a1 on the right.

Other asymmetries are also conceivable in which the distance a2 to the left from the left outer wall 13 differs from the intermediate space between the

webs

11a, 11b arranged next to one another.

It becomes clear, moreover, that the electrical contact elements 10 at, behind or between the respective webs 11a of the first type having a height H1 develop a first contact plane which is higher than the contact plane of the electrical contact elements 10 of the lower webs 11b of the second type having a height H2 (H1 > H2). The electrical contact elements 10 of the narrower and lower connecting piece 11b of the second type also extend out of a common second contact plane.

The higher tabs 11a of the first type having a width B1 are wider than the lower tabs 11B of the second type having a width B2 (B1 > B2).

Fig. 4 shows a front view of the electrically conductive profile 1. Here too, it can be seen that the electrical line 5 which is placed in the deeper groove 4a of the first type opens out into a first contact plane E1. The electrical conductors 5 placed in the lower slots 4b of the second type conversely develop a second plane E2 parallel to the first plane 1.

It is also clear that the

adjacent grooves

4a, 4b each have a common side wall, and that the second type of groove 4b is thereby inserted by a second type of web, which projects parallel to one another in the common plug-in direction from the first plane E1. The side walls of the connecting sheet-like structures are the groove side walls of the corresponding deeper grooves 4a of the first type.

Fig. 5 shows a front view of the conductive profile 1 described above, with the plug-in connector 2 plugged thereon. It will now become clear that in each case one

lug

11a, 11b of the tap plug connector 2 dips into the associated

groove

4a, 4b of the conductive profile 1. In this case, the electrical contact elements 10 of the respective connecting

lug

11a, 11b each touch the associated connected electrical line 5 in the

groove

4a, 4b, into which the respective connecting

lug

11a, 11b is immersed.

The outer wall 13 of the tap plug connector 2 rests against the side wall 14 of the conductive profile 1, so that the tap plug connector 2 surrounds the conductive profile 1.

Fig. 6 shows a view of an electrically conductive profile 1 with a tap plug connector 2 plugged laterally offset in a second incorrect plugging position. Here, only the left outer wall 13 dips into the first type of wider groove 4a of the electrically conductive profile 1. However, the wider webs 11a of the first type each rest on a side wall of the deeper grooves 4a of the first type, which at the same time delimits the adjacent lower grooves 4b of the second type, due to the asymmetry of the tap plug connector 2. The electrical contact elements 10 of the tap plug connector 2 are thereby distanced from the electrical lines 5, so that an electrically conductive connection between the electrical lines 5 and the electrical contact elements 10 is reliably prevented.

Fig. 7 shows a conductive profile 1 with a tap plug connector 2 plugged in a third incorrect plugging position. The tap connector 2 is here rotated by 180 ° compared to the first and second incorrect plugging position and the correct exemplary embodiment shown in fig. 1 and 5. By virtue of the asymmetrical arrangement of the alternately arranged groups of

webs

11a, 11b next to one another in the installation space defined by the outer wall 13, the higher webs 11a of the first type are now not aligned with the deeper grooves 4a of the first type. The same applies to the lower webs 11b of the second type and the associated lower grooves 4b of the second type. This results in the fact that the higher webs 11a of the first type each rest on a side wall which delimits the deeper grooves 4a of the first type and the adjoining lower grooves 4b of the second type. In this case, the electrically conductive connection of the contact element 10 to the electrical line 5 is also reliably prevented.

Fig. 8 shows the conductive profile 1 with the tap plug connector 2 in the third mis-plugging position according to fig. 8 from the other side. Here, the misalignment ensured by the asymmetry of the conductive profile 1 and the plug connector 2 becomes clear as well. It can be seen that the conductive profile 1 has on the right side a side wall 18 that is thicker by the amount D1 than the other side walls between the

grooves

4a and 4b of the first and second type.

Fig. 9 shows a conductive profile 1 with a tap plug connector 2 plugged in a fourth incorrect plugging position. The left-hand outer wall 13 of the tap plug connector 2 is here recessed into the wider groove 4a of the first type. In this case, the higher webs 11a of the first type of the plug connector 2 rest on the side walls 17 of the

grooves

4a, 4b and prevent the plug connector 2 and the conductive profile 1 from being plugged together further. The electrical contact element 10 is also not able to be brought into electrically conductive contact with the electrical line 5 of the electrically conductive profile 1.

Fig. 10 shows the combination of the tap plug connector 2 and the conductive profile 1 in a fifth incorrect plugging position from a side of the tap plug connector 2 differing from fig. 10, wherein the tap plug connector is plugged onto the conductive profile 1, which is likewise rotated by 180 ° compared to fig. 10. The fifth incorrect plug-in position corresponds to the incorrect plug-in position in fig. 10, with the difference that the tap plug connector 2 is offset to the left compared to fig. 10 and is rotated by 180 ° in the viewing direction. In the incorrect plug-in position, the left outer wall 13 is completely recessed into the deeper groove 4a of the first type. The higher webs 11a of the first type of the tap plug connector 2 are arranged here in a correct alignment with the deeper grooves 4a of the first type of the conductive profile 1 and are partially recessed therein. Continued plugging together is prevented by the higher outer wall 13, which is supported at the groove bottom of the deeper groove 4a, compared to the higher web 11 a. In this case, the electrically conductive connection of the electrical contact element 10 to in each case one electrical line 5 of the electrically conductive profile 1 is also reliably prevented.

Fig. 11 shows the electrically conductive profile 1 with the tap connector 2 inserted in an inverted manner relative thereto. The tap connector 2 is additionally rotated by 180 ° in this case so as to be oriented relative to the conductive profile 1 also in the incorrect plugging position. It becomes clear that, due to the asymmetry of the conductive profile 1 and the plug connector 2, the left, wider side wall 18 of the conductive profile 1 rests on the outer wall 13 of the plug connector 2. It cannot move to the right in the viewing direction either, since this is prevented by the outer wall 13 on the right and the side wall 17 of the lower groove 4b of the first type sinking into the intermediate space between two higher webs 11a of the first type.

Fig. 12 shows a perspective view of the plug connector 2 of the drop type. It can be seen that the higher webs 11a of the first type are formed by a plurality of struts which extend in the web direction and extend parallel to one another in a common direction of extension. Between the two legs, retaining elements 19 are provided, into which one electrical contact element 10 is inserted.

Conversely, the lower connecting piece 11b of the second type has an opening through which the electrical contact element 10 passes.

The tap plug connector 2 can be fitted selectively with the electrical contact elements 10 by using the retaining elements 19 fitted in alignment between the two legs. In the holding element 19, terminals are then also inserted as required for clamping the electrical conductor 16 introduced into the conductor insertion opening 15.

It can also be seen that the outer wall 13 does not have a thickness that remains constant over the length of the plug connector 2, but rather has a recess. This is optional.

It can also be seen that the tap plug connector 2 has a base element 21 on the side opposite the electrical contact element 10, which is likewise optional.

Fig. 13 shows a perspective view of the plug connector 2 of fig. 13 from the rear side. Reference can be made to the above.

It becomes clear that a row of successive pillars constitutes a higher connecting piece 11a of the first type, respectively.

Fig. 14 shows a top view of the plug-and-socket connector 2 from fig. 13 and 14. It becomes clear here that an electrical contact element 10 is provided for each connecting

lug

11a, 11b of the first and second type, respectively, which is arranged in alignment with the respective connecting

lug

11a, 11b of the first and second type and can be integrated into said connecting

lug

11a, 11 b.
