Technical Field

The invention relates to a device for pre-positioning a profiled clamp and to a connecting system.

Background

A profiled clamp is used to connect a wire to another wire. For this purpose, the profiled clamp is placed on the flange of the wire end piece surrounding the wire to be connected and is tightened. In order to make the connection operation easier, twisting of the unstrained profile clamp on the wire end piece should be avoided. The tensioning device of the profiled clamp is thus held in a defined position, so that the tensioning device is held in an easily accessible position. Furthermore, the profile clip can be prevented from slipping off the wire termination.

For this purpose, for a profile clamp having two half-clamps connected to each other by means of a joint, it is known from WO 2017/149104 a1 that the joint has a latch which is connectable in a holder connected to the wire end piece. The bracket fixes the position of the profiled clamp.

Disclosure of Invention

An object of the present invention may be considered to be to provide an improved device for pre-positioning profiled clamps which may be produced more economically and more easily.

The main features of the invention are specified in claims 1 and 8. The improvements form the subject matter of claims 2 to 7 and 9 to 13.

In a device for pre-positioning a profiled clamp for connecting a plurality of wire end pieces, wherein the device has a bridge element of a profiled clamp and a flange element at one of a plurality of wire end pieces, wherein the bridge element is designed to connect two jaws of the profiled clamp in a bridging direction, wherein the bridge element has a finger; the finger extends at least partially transversely to the bridging direction away from the bridging element and has a free end, the invention provides that the flange element comprises a recess for receiving the free end, the recess blocking a movement of the free end in a circumferential direction of the flange element, wherein the finger has a spring arranged between the bridging element and the free end, wherein the spring in an untensioned state arranges the free end at a greater distance from the bridging element than in a tensioned state, wherein in the tensioned state of the spring the free end is arranged in the recess.

In the present invention, a connection between the profiled clamp and the wire end piece is provided to avoid radial twisting of the profiled clamp on the wire end piece to be connected without adding additional parts on the wire end piece to be connected. For this purpose, on the flange element of one of the two wire end pieces to be connected, a groove is provided which is able to receive the finger of the bridging element of the profiled clamp. If the free end is arranged in the groove, the free end of the finger is fixed in position in the circumferential direction by the groove. The fingers are designed to be rigid in the bridging direction, that is to say they cannot move relative to the bridging element in the bridging direction. This means that the finger and the profile clamp are thus not movable in the circumferential direction of the wire end piece and are thus not rotatable in the wire end piece. Thus, no additional element is required on the wire end piece to resist twisting of the wire end piece. The free end is also resiliently mounted relative to the bridge element by means of a resilient element. Furthermore, when the free end portion is disposed in the recess, the resilient portion urges the free end portion into the recess. This has the effect that the free end is forced into the groove as soon as the free end and the groove are aligned with each other, i.e. as soon as a profiled clamp is arranged in a suitable rotational position on the flange element. Furthermore, once the free end is arranged in the groove and the profiled clamp is arranged on the flange element, the free end is held in the groove. Thus, the expenditure in the production process of the device is reduced. Furthermore, the saving of components saves costs and weight.

The fingers may extend at least partially away from the bridge element in an axial direction of the profiled clamp.

Thus, the fingers do not project directly from the bridging element between the clamp portions of the profiled clamp. Thus, jamming of the fingers between the jaws is avoided when the jaws are moved towards each other. However, this does not exclude that the fingers extend between the jaws in a subsequent process.

Furthermore, the free end can at least partially overlap the bridging element in a radial direction of the profiled clamp.

Thus, a further portion of the free end portion may extend back to the bridging element and engage around the clip. Thus, the fingers may extend all the way to the flange elements when the bridge elements and the flange portions are arranged to overlap.

The bridge element and the fingers may be integrally formed.

The fingers and the bridging element can thus be produced simply and economically in several production steps. Thus, the bridge element may be punched out of the metal sheet, for example, together with the fingers, which then reach their final shape by means of a bending operation.

Furthermore, the recess may be a depression of the flange portion, the depression extending in a radial direction of the string end piece.

Thus, the free end portion can be introduced into the groove in the radial direction of the wire end piece. This simplifies the operation of the device.

The recess may be delimited in the circumferential direction of the string end piece by two opposing wall elements, the distance between which is designed to match the width of the free end.

Thus, the free end in the groove is held in a snug manner in the groove in the circumferential direction of the wire end piece by the two wall elements. This effectively prevents the profiled clamp from rotating in the circumferential direction of the wire end piece.

The bridging element may be a junction between the two jaws.

The two jaws can thus be rotated relative to one another by means of the bridging element in order to open the profiled clamp. Furthermore, since the bridging element has the fingers in conjunction with the grooves on the flange element, the bridging element is thus multifunctional, and rotation of the profile clamp in the circumferential direction of the wire end piece can be avoided.

The invention also relates to a connection system comprising a profiled clamp with two clamping parts, a wire end part and a device according to one of the preceding claims, wherein the device connects the profiled clamp to the wire end part, wherein the profiled clamp has the bridging element and the wire end part comprises the flange element.

The advantages and effects and developments of the connection system result from the advantages and effects and developments of the device described above. Therefore, reference is made in this respect to the preceding description.

Furthermore, the free end portion may be arranged in the groove when the profiled clamp extends around the flange element.

Thus, the free end is also arranged in the groove when the profiled clamp extends around the flange element in the untensioned state. In this way, a pre-positioning is achieved even in the untensioned state of the profiled clamp.

Furthermore, the bridging element may connect the two clips to each other.

The bridging element can be arranged outside the profiled clamp in the radial direction of the profiled clamp.

Thus, during the production of the profiled clamp, the bridging element can be fixed to the clamps without a great deal of effort in order to connect the clamps to one another.

Furthermore, the finger may extend at least partially between the two clips.

Thus, when the bridge element and the flange portion are arranged to overlap, the fingers may extend all the way to the flange element.

In the radial direction of the profiled clamp, the distance between the free end and the bridging element corresponds in size at least to the distance corresponding to the reduction in diameter of the profiled clamp when the profiled clamp is tightened.

Thus, when the profiled clamp is arranged on the wire end piece in an untensioned state, the finger extends with the free end to the groove. Thus, the displacement distance of the profiled clamp in the radial direction corresponds to a reduction of the diameter of the profiled clamp, thus not causing the free end to leave the groove.

Detailed Description

The device for pre-positioning the profiled clamp will be designated in its entirety by reference numeral 10 in the following.

The device 10 according to fig. 1a serves to pre-position a profiled clamp 12, which is designed for connecting a plurality of wire end pieces 14, 16. The profiled clamp 12 has two clamping parts 22, 24. The device 10 has a bridging element 18 of a profiled clamp 12 and a flange element 20 at one of the wire end pieces 14, 16.

In fig. 1a, the flange element 20 is arranged on the wire end piece 16 and connected thereto. Alternatively, however, the flange element 20 may likewise be arranged on the line end piece 14 and connected thereto.

The flange element 20 has a groove 32, which groove 32 extends in the radial direction of the wire end piece 16. In the circumferential direction of the flange element 20, the recess 32 is delimited by mutually opposite wall elements 36, 38. The recess 32 may be a depression of the flange element 20.

The bridging element 18 is shown in more detail in fig. 1b, the bridging element 18 connecting the two clip parts 22,24 of the profiled clamp 12. Furthermore, the bridging element 18 is arranged outside the profiled clamp 12 in the radial direction of the profiled clamp 12.

The connection of the two clips 22,24 is made in the bridging direction 26. This means that the bridging element 18 extends between the two clips 22,24 in the bridging direction 26.

The bridging element 18 is the junction between the two jaws 22, 24. The clips 22,24 can be moved in an articulated manner relative to one another by means of the bridging element 18. The profiled clamp 12, which is shown in more detail in fig. 1c, can thus be opened and closed by means of the bridging element 18.

Furthermore, the bridging element 18 has fingers 28, which fingers 28 extend at least transversely away from the bridging element 18 into the bridging direction 26. Along the path of the fingers 28, the direction in which the fingers 28 extend can vary, that is to say the direction in which the fingers 28 have the extension directly at the connection with the bridging element 18 can vary along the fingers 28.

According to fig. 1b, the fingers 28 initially extend away from the bridge element 18 for a subsequent change of direction. The finger 28 has a free end 30, the free end 30 pointing directly in a different direction than the direction of extension of the finger 28 at the connection of the finger 28 with the bridging element 18.

Between the free end 30 and the bridge element 18, the finger 28 also has a resilient portion 34. The elastic portion 34 may be U-shaped. The portion 33 of the finger 28 between the elastic portion 34 and the free end 30 may act as a lever arm, so that the elastic portion 34 is tensioned during the displacement of the position of the free end 30 across its extension.

The bridge member 18 and the fingers 28 may be integrally formed as a single piece. This means that during the production of the bridging element 18 the fingers 28 are also produced simultaneously. For this purpose, the bridging element 18 with the fingers 28 can be stamped from sheet metal, for example. The resilient portion 34 of the fingers 28 may then be formed. This can be achieved by bending the fingers 28.

If the bridging element 18 is arranged on the profiled clamp 12 and connects the two clamp parts 22,24 to one another, the fingers 28 extend at least partially away from the bridging element 18 in the axial direction of the profiled clamp 12. Furthermore, the free end 30 at least partially overlaps the bridging element 18 in the radial direction of the profiled clamp 12 and extends at least partially between the two clamp parts 24, 26.

The free end 30 may be received in the recess 32. For this purpose, the two wall elements 36,38 have a distance in the circumferential direction of the flange element 20, which is designed to match the width of the free end 30. The distance between the two wall elements 36,38 may correspond to the width of the free end 30 or be large enough for the free end 30 to be inserted into the recess 32 and to establish contact with the two wall elements 36, 38.

The free end 30 is thus fixed in the circumferential direction of the flange element 20 by the two wall elements 36,38 of the recess 32. Thus, at the same time, the bridge element 18 and the profiled clamp 12 are fixed in the circumferential direction of the flange element 20 and are thus pre-positioned on the wire end piece 16.

The profiled clamp 12 and the wire end piece 16 form a connection system with the device 10, which is designated in its entirety by 40 when the device 10 connects the profiled clamp 12 to the wire end piece 16. The free end 30 can be arranged in the groove 32 when the profiled clamp 12 extends around the flange element 20.

In fig. 2a and 2b, various states of the connection system 40 are illustrated. The two fig. 2a and 2b form a cross-section through two wire end parts 14,16, the two wire end parts 14,16 being coupled to each other and a seal 42 being arranged between the two wire end parts 14, 16. Furthermore, the profiled clamp 12 is arranged around the two wire end pieces 14,16, in particular around the flange element 20.

In fig. 2a, the profiled clamp 12 is in an untensioned state. The grooves 32 and the fingers 28 are aligned with one another such that the free ends 30 and the grooves 32 are aligned with one another. The fingers 28 are designed such that, in the untensioned state of the profiled clamp 12, the free ends 30 are arranged in the grooves 32.

The portion 33 between the free end 30 and the spring 34 is arranged at an angle to the axial direction of the profiled clamp. The angle of the portion 33 may, for example, be between 60 ° and 20 ° with respect to the axial direction of the profiled clamp when the elastic portion 34 is not tensioned.

In fig. 2a, the free end 30 is arranged in the recess 32. One wall of the recess 32, running in the circumferential direction of the flange element 20, is in contact with the free end 30. A small amount of force applied to the free end 30 in the direction of the bridging element 18 may act on the free end 30. This causes a slight tension of the elastic portion 34. The spring 34 drives the free end 30 in the radial direction of the profiled clamp 12 towards the flange element 20.

As the profile clamp 12 is tightened, the diameter of the profile clamp 12 decreases, so that the distance between the profile clamp 12 and the flange element 20 decreases. This state is illustrated in fig. 2 b. As a result of the reduced diameter of the profiled clamp 12, the distance of the bridge element 18 from the flange element 20 and thus also the distance of the bridge element 18 from the groove 32 is reduced. Thus, the free ends 30 of the fingers 28 are displaced further in the radial direction in the direction of the bridge element 18. This achieves an increase in the tension of the elastic portion 34. The fingers 28 in fig. 2b are deformed compared to the situation shown in fig. 2 a. In fig. 2b, the spring part 34 drives the free end 30 into the recess 32 in the direction of the flange element 20 with a greater force than in the state of fig. 2 a.

Thus, in the radial direction of the profiled clamp 12, the distance between the free end 30 and the bridge element 18 corresponds in magnitude at least to the distance corresponding to the reduction in the diameter of the profiled clamp 12 when the profiled clamp 12 is tensioned.

The invention is not limited to one of the previously described embodiments but can be modified in many ways.

All the features and advantages, including design details, physical arrangements and method steps, which are derived from the claims, the description and the drawings, may be essential to the invention, both as such and in various combinations.
