Definitions

the invention relates to a tension spring connection for electrical conductors, in particular for use in fixed-pole housings, according to the preamble of claims 1 and 17, respectively.
Tension spring connections for electrical conductors consist of an approximately loop-shaped tension spring, one end area of which forms a leg for resting on a conductor rail and the other end region of which is a leg oriented approximately perpendicular to the conductor rail.
this leg which is oriented perpendicular to the conductor rail, there is a window for the passage of the conductor rail, the lower edge of which forms a clamping edge for clamping a conductor under the conductor rail.
Tension spring connections of this type are frequently used in connection elements in what is known as a disk design, in which individual plastic disks are assembled to form multipole connection strips.
a preassembled module consisting of busbar and tension spring is inserted into the respective housing pane from the side in a manner that is suitable for assembly and function.
the pre-assembled bandage is used for this purpose and tension spring attached to a molded on the plastic housing of the disc stop cam which comes to rest within the loop-shaped spring and limits the spring travel of the tension spring due to its dimensions.
a tension spring connection of the generic type in which the tension spring itself has a stop for limiting the spring travel of its opening movement or a passage for such a stop provided on the busbar.
suitable elements for the spring travel of the tension spring are realized by means of shaped elements either on the tension spring itself or on the busbar, a number of exemplary embodiments with formation of stop elements from the sheet metal parts of tension spring or busbar being shown.
the problem with such a limitation of the stroke of the tension spring is that complex sheet metal machining of the tension spring or busbar, which requires complicated tools, is required to produce the suitable stop elements.
an assembly of the sheet metal parts of the tension spring or conductor rail deformed in this way is not entirely unproblematic due to the shape and mounting options.
the object of the present invention is therefore to provide a tension spring connection for electrical conductors, in particular also for use in fixed-pole housings, which reliably prevents overloading of the tension spring by mechanical actuation forces with simple installation options and inexpensive shaping of stop elements.
the essential idea of the tension spring connection according to the invention is to design the stop element as a separate component which can be inserted into the loop-shaped region through the window of the tension spring or through the side openings formed by the tension spring and can be fixed on the tension spring.
the stop element which can have different external contours in shape, also pronounced of the known stop cams of the disk construction, is introduced into the interior of the loop-shaped tension spring as an isolated or to be separated component. It is possible to insert the stop element through the window of the tension spring, which is oriented in the direction of insertion of the conductor, which makes it possible to insert the stop element later, especially when the tension spring and busbar are already connected in a housing.
a pre-assembled bandage of busbar and tension spring with a stop element before inserting it into a suitable housing, which is inserted through the two lateral openings in the loop-shaped area of the tension spring and together with the pre-assembled bandage of busbar and tension spring in the housing is arranged.
a stop element can also be inserted into the tension spring and this pre-assembled bandage can be attached to the conductor rail. The assembly thus completed can then be arranged as a whole in the housing. It is particularly important here to fix the stop element by means of suitable measures on the tension spring or the busbar in such a way that the stop element is prevented from falling out of the interior of the tension spring for any further necessary handling operations.
the separation of the stop element and tension spring or busbar makes it possible, in addition to the economic advantages of simplified assembly, in particular to use tension spring elements with suitable stop limits even with fixed-pole housings with small pitch spacings and a large number of poles. It is also possible to achieve an inexpensive and largely automatable prefabrication of the tension spring connections according to the invention by using plastic materials for the stop elements and the associated manufacturing possibilities.
Sub-claims 2 to 16 show further advantageous embodiments of the tension spring connection according to the invention.
the stop element is fixed to the tension spring in such a way that the stop element in the section of the loop-shaped bent area opposite the window of the tension spring the tension spring, preferably evenly, is spaced. This ensures that when the tension spring is deformed, for example when a conductor is inserted into the window, the loop-shaped region of the tension spring can deform without contacting the stop element. This ensures that the tension spring abuts the stop element in a zone through which the line of action of the actuating force runs. This leads to a particularly safe protection of the tension spring. Such a stop keeps the attack force, for example of an actuating tool, away from critical areas of the tension spring.
the stop element rests at least in sections on the inside of the loop-shaped region of the tension spring.
the fixing is designed to be latchable.
the stop element is fixed on the boundary edges of the window of the tension spring.
the shape of the window of the tension spring can be changed in such a way that positive or non-positive fastening of associated parts of the stop element can be achieved.
the stop element is fixed to the area of the tension spring assigned to the busbar. Another embodiment provides that the stop element is non-positively fixed in the interior by the spring action of the tension spring itself.
the stop element is preferably fixed in its longitudinal extent on the prestressed tension spring and is therefore held in a force-fitting manner by the spring action, the provision of fixing elements is not necessary.
a preferred embodiment with regard to the shape of the stop element provides that the stop element is essentially rigid and its outer contour is adapted to the shape of a loop to the loop-shaped contour of the tension spring.
a solid area is provided, which is separated by a narrower area from the again solid area near the window of the tension spring. This results in a shape of the stop element reminiscent of a bone shape.
stop element consists of essentially V-shaped legs, in which the outer contour of the stop element is adapted to the loop-shaped contour of the tension spring and the V-shaped legs of the stop element are elastically deformable when the tension spring is actuated.
the stop element is likewise held securely in the inner region of the tension spring by the spring action of the tension spring, without having to provide shaped elements for positioning.
the stop element is introduced into the interior of the loop-shaped region when the tension spring is not preloaded.
the tension spring is pretensioned by the busbar during assembly of the stop element and the stop element is inserted into this pretensioned spring.
the stop element can be held in place as an injection molded part or arranged on holding belts.
a further embodiment consists in that the stop element can be held as part of an endless injection molding tape, the individual stop elements being separated from the endless injection molding tape for assembly at predetermined breaking points and fed to the assembly point.
the stop element can also be provided as a continuous casting profile, which is cut to length from this continuous casting profile only for assembly in a corresponding dimensional design.
the stop element can be introduced directly into a tension spring inserted into an injection molding tool.
a tension spring connection according to the invention, the stop element of which is formed in one piece with surrounding wall areas of a fixed-pole housing and projects through the window into the loop-shaped inner region of the tension spring or can be inserted.
a stop element is provided in one piece in a wall area of the fixed-pole housing assigned to the window of the tension spring in such a way that it is connected to the wall area via a narrow web, which is assigned to the wall area in accordance with the function and tension spring passes through the window of the tension spring and thus positions the stop element inside the tension spring.
a particularly advantageous embodiment provides for the insertion of the stop element inevitably by assigning, for example, the wall area associated with a cover part when the cover is closed.
connection 1 or claim 16 show particularly preferred exemplary embodiments of the tension spring connections according to the invention according to connection 1 or claim 16.
FIGS. 1 to 9 show different embodiments of the tension spring connections according to the invention as claimed in claims 1 and 17, the same reference numerals representing elements of the same function within the tension spring connection.
part numbers of individual drawings which are not explained, reference is made to the description of functionally identical components in other drawings.
FIGS. 1a to 1d show a first embodiment of the tension spring connection 1 according to the invention, in which the tension spring 1 comprises, in a generally known manner, an area 4 assigned to a conductor rail (not shown), an adjoining loop-shaped area 5 and an area in turn arranged thereon , Area 3 assigned to the window of the tension spring is formed.
the window 6 is arranged, through which, in the deformed configuration of the tension spring connection, a conductor, not shown, is inserted and clamped under the section of the busbar, also not shown.
the tension spring connection is arranged in the known manner, for example in an insulating housing, preferably a housing with a fixed number of connection poles
the area 4 associated with the busbar is elastically deformed in such a way that its end assigned to the window 6 is seen in the insertion direction in the window 6 comes to rest.
the insertion process of a conductor (not shown) into the window 6 takes place in such a way that the loop-shaped region 5 of the tension spring 1 is elastically deformed with a corresponding actuating tool and the window 6 thereby opens an insertion opening relative to the busbar.
a stop element 2 which is arranged inside the tension spring 1.
Such a stop element 2 serves to protect the tension spring 1 against impermissible deformations, which would weaken the restoring force and contact stability and would endanger the gas tightness of the conductor connection. At the same time, this would increase the resistance of the tension spring 1 reduced against pull-out.
1a to 1d is formed here by a prismatic body which is preferably made of insulating material and which appears to be bone-shaped in its contour, which can be inserted in the direction of the assembly direction 12 through the window 6 into the interior of the loop-shaped region of the tension spring 1 and there can be fixed in the corresponding region 8 of the window 6 by means of a fixing bolt 7.
the stop element 2 is inserted into the undeformed tension spring 1 through the window 6 and the stop element 2 is then tilted such that the holding element 7 can engage in the counter-shape 8 of the tension spring 1.
the stop element 2 comes to lie at a distance from the inner surfaces of the tension spring 1 such that a preferably uniform gap 9 is created between the stop element 2 and tension spring 1.
the deformation behavior of the tension spring 1 is unchanged up to the point of contact with the stop element 2.
FIGS. 2a to 2d A further embodiment of the tension spring connection according to the invention is shown in FIGS. 2a to 2d, which basically corresponds to the structure according to FIG. 1, but has the holding element 7 in the form of a bar-shaped extension on the stop element 2, which can be inserted into a correspondingly enlarged window 6 of the tension spring 1.
This approach 7 is provided on one head side with a chamfer 10 in order to be easier to assemble and still achieve a secure fixing.
the stop element 2 is inserted laterally into the interior space formed by the tension spring 1 and then pivoted into the mounting position.
a preferably uniform gap 9 also forms between the stop element 2 and the tension spring 1.
FIGS. 3a and 3b A variant of the embodiment of the stop element 2 according to FIG. 2 is shown in FIGS. 3a and 3b.
assembly is also possible through the window 6 of the tension spring 1, in that the stop element 2 is provided with a spring slot 11 along its main direction of extension, which enables the legs of the stop element 2 separated by the spring slot 11 to spring together or spring open. Due to this essentially U-shaped configuration of the stop element 2, the stop element 2 can be pushed through the window 6 in a state deformed by pressing the two legs together. After insertion, the limbs of the stop element 2 delimiting the spring slot 11 spring back and lie on the inner edges of the window 6 of the tension spring 1, which is enlarged by a corresponding amount.
a further improvement of the assembly results from a conical shape of the stop element 2, which has a conical shape of the side faces towards the bottom of the spring slot 11 and therefore has a smaller dimension than the width of the window 6 of the tension spring 1.
FIGS. 4a to 4d show a further embodiment according to claim 1, in which the stop element 2 is fixed in the area 4 of the tension spring 1, which is assigned to a busbar, not shown.
a lateral notch 8 is formed in this area 4 of the tension spring 1, to which a bracket-like area 7 of the stop element 2 can be assigned by insertion.
the insertion direction 12 is lateral to allow the insertion of the console-like shoulder 7 of the stop element 2.
FIGS. 5a to 5d show a variant of the embodiment according to FIGS. 4a to 4d, which enables assembly through the window 6 of the tension spring 1.
a bolt-shaped extension is provided on the stop element 2, which can be inserted into a groove-shaped, narrowing counter-shape 8 of the area 4 of the tension spring 1.
the stop element 2 is inserted through the window 6 into the inner region of the tension spring 1 and pivoted in such a way that the bolt 7 comes to rest in the wide area of the counterform 8.
the stop element 2 is fixed by further insertion into the narrowing counter-shape 8.
mounting by lateral insertion into the tension spring 1 is also possible.
FIGS. 6a to 6d show a further variant of the tension spring connection according to the invention, which does not require any holding elements for fixing the stop element 2 on the tension spring 1.
the stop element 2 is dimensioned such that the dimensional design in the main direction of extension corresponds at least to the inside dimension of the tension spring 1, whereby the tension spring 1 is slightly sprung when the stop element 2 is inserted laterally into the mounting direction 12. Due to this spring action, the stop element 2 is clamped and can no longer fall out of the interior of the tension spring 1.
the stop element 2 is inserted into the tension spring 1 in a deformed configuration of the tension spring 1, which is carried out by proper installation with the busbar, not shown.
the tension spring 1 is positively steered via the stop element 2, in the window area 6 and opposite the window area 6, the stop element 2 lies on the inside of the tension spring 1 on. With this design, the accuracy of the assembly can be significantly reduced.
FIGS. 7a to 7d and, in a variant, FIGS. 8a to 8d show a further embodiment with the stop element 2 lying against the inner region of the tension spring 1.
the stop element 2 is formed from a body which consists essentially of V-shaped legs, the shape and dimensions of which are adapted to the intended deformed inner contour of the tension spring 1 after plugging onto a busbar region, not shown.
the assembly is carried out by inserting from the side, the stop element 2 clamps automatically in the interior of the tension spring 1, similarly to FIG. 6, due to the deformation of the tension spring 1. Due to the shape of the stop element 2 and the material used, preferably made of insulating material, the V-shaped stop element 2 can also be deformed when the tension spring 1 is deformed.
the spring properties of the tension spring 1 can be influenced by such a shaping of the stop element 2.
the stop element 2 is preferably in full contact with the inner surfaces of the deformed tension spring 1.
FIGS. 8a to 8d show a variant with additional fixing of the stop element 2 by a bolt 7 which can be inserted into a corresponding opening in the area 4 of the tension spring 1.
the stop element 2 is inserted into the interior of the tension spring 1 before the tension spring 1 is deformed and brought into contact with the bolt-shaped holding element 7 by the deformation of the opening 8.
the pre-assembled module is plugged onto the busbar or it can also be plugged onto the busbar beforehand.
FIGS. 9a to 9c show an exemplary embodiment of a tension spring connection.
the stop element 2 is arranged in one piece by means of a connecting web 14 on a region of the housing wall 13 and, after the tension spring 1 and the housing wall 13 have been assigned, projects through the window 6 of the tension spring 1 into the interior thereof.
the connecting web 14 is formed to match the dimensions of the window 6, in particular an additional recess 15 is provided on the window 6, which receives the web 14 in the actuated state of the tension spring 1 and allows the tension spring 1 to spring together as intended.
the housing wall 13 is part of a cover that closes a preassembled number of tension springs 1 within a housing.
the locking movement is used to insert the stop elements 2.
the tension spring 1 is preassembled in the position already connected to the busbar, not shown, as intended.
