DEVICE FOR CONTINUOUS ELECTRICALLY CONNECTING

The invention relates to a device for electrically conductive contacting referred to in the preamble of claim 1 for electrically conductive contacting a

electrically conductive, in particular elongated, for example substantially cylindrical body, for example a pipe or a cable. A relevant cable can be designed, for example, as a fiber optic cable, whose outer circumference is at least partially electrically conductively coated, for example by means of an electrically conductive metal mesh or an electrically conductive shield.

Such devices for electrically conductive

Contact are in different forms,

for example u. a. Also known as a so-called grounding clamp.

A device for electrically conductive contacting an electrically conductive part of a pipe or cable is u.a. known from EP0744788A1, in particular, an electrically conductive connection between a stripped outer conductor of a coaxial cable and a conductor, for example a

Grounding cable, serves.

By EP 0 987 483 Bl, EP 0 982 524 Bl and EP 978678 Bl, a device is known in each case, as one to

Carrier element has, which is designed to be open in the circumferential direction and the connecting means, through which the in

CONFIRMATION COPY Circumferentially free ends of the support element in

Mounting position are connected or connected to each other.

In addition, the known devices comprise contact means for producing an electrically conductive connection between the body to be contacted and a conductor, in particular a grounding cable.

In the devices of the known type, the

Connecting means, for example by screw or

Riveted formed, with z. B. a free end of

Carrier element has at least one threaded bore into which the screw acting as a connecting member for a connection with the remaining end of the support element is screwed. The screw is guided through a recess at the aforementioned remaining end.

The known devices are to secure the realization of a firm hold on the body to be contacted by the connecting means accordingly. It has been found that comparatively many individual parts or tools are used to connect the free ends of the carrier element in the mounting position with each other.

The invention has for its object to provide a device that a temporally faster and also

securely connecting the ends of the support member allows and also a secure electrical contact of a

electrically conductive body allows.

To solve the task posed it solves the

Invention first of the thought, the necessary

Connectors in their dimensions and design to make the same, to handle the attachment of the

Simplify link.

Furthermore, the invention moves away from the basic idea that the free ends of the carrier element are inextricably linked to one another connect, whereby the ends of the support element only by

Destruction of each other would be separable, then to be able to remove the initially designated device of the respective electrically contacted body.

In contrast, the invention also pursues the

Objective to realize a resource-saving solution with which the number of different parts can be reduced and with the same secure connection of the ends of the

Carrier element is possible.

The invention is based on the solution of their task initially the basic idea to change the nature of the connection to a secure connection of the free ends in the circumferential direction of the set as a tensionable clamp and

to achieve trained carrier element in that a connecting member is used to through this one

positive connection by means of a, in particular in

Essentially exclusively, translational movement of the

Can be realized link member in the resulting axial position in the mounting position for the movement of the support element.

The aforementioned axial direction of a device according to the invention for the movement of the carrier element results in the mounting position initially transversely to the circumferential direction, in which the carrier element encloses or electrically surrounds the body to be electrically contacted in its construction as a tensionable clamp and thus finally spans.

Furthermore, the aforementioned axial direction of a device according to the invention results in longitudinally extended bodies, in particular parallel or substantially coaxial with respect to Longitudinal extent of the body to be electrically contacted or its contacting portion, which is provided for the assembly of a device according to the invention.

Against this background, there are time and cost advantages for assembly and disassembly as well as maintenance.

Furthermore, there is the advantage that the number of necessary for the functional performance of a device according to the invention items is reduced compared to existing solutions. Furthermore, a secure connection of the ends of the support element is also possible without it further

Securing elements, such as adhesives or holding means required.

According to the invention therefore at least one connecting member for cooperation with guide means for translational motion guidance of the connecting member is provided, which are arranged at the free ends of the support member, set up and formed. This is done in such a way that, in the assembly position of the device, a translatory movement of the connecting element between a guide start and a guide end of the guide means brings about a, in particular non-destructively detachable, positive engagement for connecting the free ends of the carrier element.

This creates the advantage that through pure

translational movements of the connecting member is achieved in a simple manner that the free ends in the circumferential direction of the support member in the mounting position by means of

Link are connected by a positive connection with each other connectable zw.

Furthermore, there is the advantage that the ends of the carrier element formed as a clamp uniformly through the

Connecting member are connected. It is the same

possible to keep a sealant according to evenly or a corresponding uniform compressive force on the

Apply sealant.

According to the invention results from the fact that the

Link through the guide means in his

Freedom of movement is reduced to a translational movement, preferably in one direction, and thus its handling is simplified.

Furthermore, it is achieved that the freedom of movement of

Link in the axial direction to a in

Mounting position resulting clamp axis (or

Carrier element axis) is limited.

A significant advantage that arises from a translational motion control of the connecting member is that the connecting member is easy to handle, since it is possible in a simple manner that the connecting member by the guide means or guide in another, as by moved predetermined direction of movement. Accordingly, the effect Guide means a positive guidance of the connecting member for movement between the aforementioned guide start and

Lead end. As a result, a safe handling of the device is also favored.

Furthermore, it follows that by an interaction of the connecting member with those formed at the free ends

Guide means a positive connection of the free ends of the support member in a simple manner via a

additional tool, the link, is possible.

By a device according to the invention arises

Advantage that the size can be kept very low, whereby the space requirement decreases, and a compact arrangement of a plurality of electrically conductive bodies, for example as a pipe ^¬ or cable package is possible.

In addition, there is the advantage that a

inventive device is particularly simple and therefore inexpensive to produce.

In addition, there is the advantage that an inventive

Setup both at an assembly and at

Maintenance work - easy to handle. Furthermore, there is the advantage that the number of necessary individual parts of a device according to the invention for its installation on a relevant body is reduced to a minimum.

The guide means can open the connecting link

lead different way, so that a translational movement in the axial direction along appropriate

Movement curves or in degrees of freedom in accordance

different directions of movement is possible.

To further simplify the handling of a

The device according to the invention is provided that the connecting member is electrically conductive and in the mounting position in which the connecting member to the guide means for a positive connection of the free ends of the support element between a guide start and a leading end is arranged, the support member electrically contacted, in particular the conductor, preferably the ground wire, in the mounting position, preferably with one of its free, electrically conductive ends, arranged on the connecting member and electrically conductive connected to this.

For this purpose, the carrier element is formed in particular from a metal having or consisting of metal material.

For the purposes of the invention, as already explained above, a mounting position of the device is determined by the arrangement of the carrier element on the body to be electrically contacted, on which the device designed as a tensionable clamp

Form carrier element to form, for example, by a non-cutting machining or forming operations as well as by a machining on the support element. Alternatively, it is possible, for example, to use a cohesive connection.

This provides a further advantageous embodiment of

Furthermore, this results in the advantage that the production of a guide manufacturing technology is easily feasible.

The same applies to the guide element of the connecting member, which can be produced, for example, by pins or pins.

The corresponding guide surfaces of the Link and the carrier element can be reduced to a minimum, which, inter alia, manufacturing costs for a

Device according to the invention can be realized.

A translational motion guide according to the invention reduces the freedom of movement of the connecting member relative to the carrier element of the device and forms the free

Mobility of the link. As soon as the guide element and the guides between a guide start and a guide end of the guide means for positive connection of the free ends of the carrier element is carried out together for connecting the free ends of the support element by a translational movement of the connecting member relative to the guide means or the guides, it is advantageous that a further unwanted and unwanted movement of the guide member is omitted. In this regard, within the meaning of the invention, various possibilities exist, such an undesired movement of the

For this purpose, it is provided in a further advantageous development of the invention that at least one of the corresponding guide surface of the connecting member or at least one of the guide surfaces of the carrier element to their respective

Longitudinal direction, which is directed in the mounting position in the axial direction, for a self-locking holding guided by the guide means connecting member is at least partially inclined.

There is a self-locking effect between the

Joining member and the support member for holding the joining member to the support member in particular by the

Guide surface (s) of the support element with the / the

corresponding guide surface (s) of the link with respect to their respective inclination in

Longitudinal direction are coordinated. Furthermore, a self-locking effect depends on other factors, such as the respective inclination angle u.a. also the

Surface roughness of the relevant guide surfaces, the

Material pairing, the temperature of the guide surfaces as well as the presence of a lubricant. Fundamentally, for a self-locking effect, the resulting tilt angle is relevant guide surface between the guide surfaces smaller than the arc tangent of the static friction coefficient. This applies accordingly for the rejuvenation of the aforementioned

Guide groove (s).

The guide element may for example also be formed by a rail or a rail. Moreover, it is possible within the scope of the invention that the guide element of

Link is set up and designed as a guide groove, while the guide at the respective free end of the

Carrier element is designed as a projection or as a pin. The projection or pin can be formed in different ways. In a simple way this can be a pen or

Be threaded pin, which is formed for example on the connecting member. In addition, a projection may be formed by being formed as a rib having a free end. There are different ways of forming one

corresponding guide element.

To connect additional component or assembly with the support element and to hold on this. However, it is particularly cost-effective and simple if the first or second guide can be arranged on the carrier element by forming operations or

are shapeable. For this purpose is taken into account in one of the purposes of the invention, that the first and second guide is integrally formed on the support element.

An Anformung can be achieved in that the guide in question, for example, by a forming technology introducing at least one corresponding guide groove in the carrier element can be generated.

In order to achieve this according to the invention, it is advantageous that the clear dimension of the designed as a tensionable clamp

For the inventive positive connection of the free ends of the Grundköpers each other, it is advantageous that the connecting member is shaped such that it overlaps in the mounting position, the free ends of the support member for the positive connection with each other in the circumferential direction of the support element. This results in an advantageous manner a
