Description

DEVICE FOR ELECTROCONDUCTIVELY CONTACTING AN ELECTROCONDUCTIVE PART OF AN ESPECIALLY LONGISH, FOR EXAMPLE ESSENTIALLY CYLINDRICAL BODY, FOR EXAMPLE A TUBE OR A CABLE}

An apparatus of this kind is known from EP 0 744 788. It is used for electrically conducting connections between exposed conductors and exposed outer conductor cables of pipes or coaxial cables, for example ground cables.

The known device comprises a clamp-shaped base structure which fits into a band-shaped metal part in an elastic material, for example a rubber, and forms a sealing lip spaced from each other in the axial direction of the base structure.

The sealing lip is fitted with the rest of the surface by means placed on the body to which the base structure is contacted at the assembly position, and seals the space determined between the body and the base structure to be contacted at the assembly position against the penetration of air or moisture. do.

The known device also includes contact means for carrying out an electrically conductive connection between the body being in contact with a conductor, for example a ground cable.

In the known device, the contact means is in the form of a band copper strap in contact position with respect to the side of the band-shaped metal part of the base structure facing the body to be contacted on the one hand and on the other hand. It is composed of phosphorus disconnect adapter. The adapter is bonded to the base structure or connected by spot welding.

The known device is laborious and expensive, with the drawback of having to connect the disconnect adapter to the base structure in an additional stage of operation during manufacture.

In addition, the device carries the risk of slipping when the point of adhesion between the adapter and the base structure is connected to the base structure at the time of manufacture, preventing it from being fixed at the intended point of the base structure.

If so, the assembly of the device of the present invention must be removed by moving the adapter from the base structure to the intended position. This procedure is labor intensive and increases assembly costs. In addition, the connection performed by spot welding increases the risk that the adapter will loosen and lose its base structure.

In this case a new adapter must be fixed before the known device is assembled, which increases material and assembly costs and complicates manufacturing.

The present invention relates to a device for contacting a substantially elongated cylindrical body, such as a cable or pipe or tube, wherein the term “pipe” also includes the meaning of “tube”.

It is an object of the present invention to provide a device defined by the front end of claim 1 and to overcome the drawbacks of known devices by being simple and economical to manufacture and install.

This problem can be overcome by disclosing claim 1.

The present invention abandons the concept of forming contact means for conducting an electrically conductive connection between the body and the body in contact with the conductor, for example by a point adhesive adapter such as a ground cable. Instead, the concept of the present invention is to configure the contact means by the division of the base structure. For this purpose, the present invention includes one or more contact protrusions of which the base structure is electrically conductive material. A separate adapter consisting of a band copper cord is therefore no longer needed and thus the manufacture of the device of the invention is simpler and more economical.

Contact means formed as part of the base structure is neither dangerous nor damaging as is known in the art. The shape, size and location of the contact protrusions or each of the contact protrusions can be selected within wide limits depending on the particular requirements. The number of contact protrusions can likewise be selected within wide limits. In an embodiment of the present invention, the contact protrusions or each of the contact protrusions are composed of elements firmly adhered to the base structure.

By way of illustration, the contact protrusions or respective contact protrusions may be sheet metals firmly connected to the sheet metal of the base structure by welding and spraying toward the body contacted from the base structure.

Since the contact protruding portion is bonded through the base structure, the portion is fixed without shaking in the base structure. Welding allows the two elements to be bonded in a simple and economical way, which allows the device of the invention to be manufactured at low cost.

Essentially the contact protrusions or respective contact protrusions are in an assembly position between the body which is in contact with an electrically conductive conductor connected to the contact protrusions, for example a ground cable, for example via the ground cable. It may optionally be made of a material with good electrical conductivity, so long as it is sufficiently conductive to ensure the divergence of any current from the total light.

In order to minimize the electrical resistance of the contact protrusions as much as possible, the contact protrusions or each of the contact protrusions may be a suitable metallic material.

A common advantage according to embodiments of the present invention is that the contact projections or each contact projection is integrated with the base structure or part thereof. In this way the separating element no longer needs to constitute a contact means.

This feature substantially simplifies the manufacturing process of the device according to the invention and thus makes it more economical. In another embodiment, the contact protrusions or each of the contact protrusions are elastically formed against the electrically conducting portions of the conductors of the body to be contacted in an elastic manner at the assembly position.

Particularly reliable electrical connection is achieved in accordance with the elastic application of the contact projection to the electrically conducting part of the body being contacted in this embodiment.

In addition, the elastic application of the contact protrusions or each of the contact protrusions compensates for element tolerances.

In one embodiment according to the invention, the electrically conductive connection of the contact protrusions or the body in contact with each of the contact protrusions can also be improved by a spring which biases the contact protrusions or each of the contact protrusions toward the body in contact. .

By means of a suitably selected spring deflection, the force reclining at the assembly position relative to the contact projections or the body to which each contact projection is to be contacted can be selected within a wide range of constraints that meet specific requirements.

In principle, the base structure can consist essentially of rigid bodies. However, in a suitable embodiment the base structure is flexible. In another embodiment the base structure is brought into contact with the surface of the body due to its flexibility. This feature also allows for strong contact even on non-planar or curved surfaces.

In another embodiment, the base structure comprises a band-shaped or planar contact element made of an electrically conductive material, preferably a metal.

In a variant to the above embodiment, the base structure is formed on the side of the contact element which is in contact with the body in which the contact element is fixed and accordingly forms a contact protrusion or the contact protrusion or each of the contact protrusions is contacted at the assembly position. It is adapted to the side facing the body to be contacted in the contact position having one or more protrusions.

In another particularly preferred variant of the above embodiment, the contact protrusions or respective contact protrusions are formed by embossing in the contact element.

As shown, if the contact element is a metal band, the metal band may be appropriately embossed to form a contact projection or each contact projection.

This is a simple design and economically manufactured. The shape and size of the contact protrusion can be selected within a wide range of limits by means of a metal band suitably embossed.

In a variation of this embodiment, the embossing or each embossing consists of a protruding bead-shaped inflation towards the body towards the body being convex or contacting the body towards the body being contacted at the assembly position.

As shown, the contact projection is achieved by embossing a metal band having an inflation section which is convex in cross-section towards the body to be contacted, in particular circular at the top.

In this way the contact protrusions or the respective contact protrusions can be formed in a particularly simple way when the device of the invention is manufactured.

When assembling the device of the present invention, the contact projections are first formed in points and have an elastic deformation and are retained with respect to the body to be contacted by increasing planar shape and consequently a reliable electrically conductive connection is achieved in the intended manner.

Correspondingly, beads of any shape may be embossed with metal bands to form contact projections. The contact projections in this embodiment, which consist of embossing and opening, are not required in the base structure but must accommodate them when external air or moisture enters the contact zone.

For contact pipes, the device of the present invention may consist of, for example, a clamping band and when the sealing lip is included in the assembly position the side of the band faces the pipe to be contacted. Such an embodiment is particularly simple and economical to manufacture.

In another embodiment of the present invention, the contact protrusions or each contact protrusion protrudes toward the side of the base structure in which the blade or each blade selectively strikes the contact element in another variant in an assembly position in contact with the body to be contacted. It consists of a blade. This embodiment enables particularly simple and economical production.

In another embodiment, the portion of the contact element is connected in such a way as to pass through the base structure to the side spaced apart from the body being contacted at the assembly position or the contact element is electrically conductive to the element passing through the side of the base structure.

In this embodiment, when in the assembled position, contact is made by attaching a grounding cable from the outside, for example to an external element. This feature facilitates the assembly of the device of the invention.

Depending on the specific requirements, the base structure of the device of the present invention may have any structure that is flat or planar, for example to connect a bent, curved, flat or planar body to contact a bent or curved body.

The base structure is suitably enclosed in such a way that the body is in annular form or bush-like contact in the assembly position, in order to extend and contact, in particular in a substantially cylindrical body. The base structure of this embodiment is particularly reliably maintained with respect to the body to be contacted.

In another suitable embodiment, the base structure is in the form of a clamp which can be tensioned around the body being contacted. In this embodiment, there is greater reliability and simpler assembly in connecting the device of the invention to the body to be contacted.

For the above two embodiments, it is preferable that the contact protrusions or each of the contact protrusions radially protrude. In a variant of this embodiment the contact projections or each contact projection proceeds substantially in the circumferential direction of the base structure through the entire length of the structure.

The result is a large area of contact with the body to be contacted, where a reliable conduction connection is made. Contacting the body to be contacted with a large area makes it possible to ignore element tolerances in the electrical connection between the body of the invention and the body to be contacted. In another variant, two or more spaced apart contacts mounted along the circumference line on the base structure are used. In this method the contact is made with the body being contacted at some circumferential site.

In another embodiment of the present invention, the base structure consists of two or more interconnectable parts which are continuous along the circumference of the body to be contacted at the assembly position for connecting the contact pipe or the baby. In this embodiment, the base structure consists of several segments. As shown, the base structure may be composed of two semicircular portions.

In another particularly preferred variant, the base structure is joined at one end with a bracket which is integral, circumferentially open and can be connected to each other when in the assembled position. Since the base structure is integrated, the assembly of the apparatus of the present invention becomes easier.

By connecting the brackets to each other, the device of the invention is fixed faster and in a simpler way to the body in contact.

The brackets are joined in any way, for example by welding to each other. However, in a preferred embodiment the brackets can be connected to each other by screws or clamps. This feature also simplifies the assembly of the device of the invention.

Also the interconnection of the brackets and the connection of the device of the invention to the body to be contacted are made removable in this variant. As a result, the device of the present invention is selectively reusable.

In another embodiment, the base structure includes an elastic material portion whose side facing the body being contacted at the assembly position is connected with the contact element.

If the base structure is in the form of a clamp, the elastic part can deform when the clamp is tightened and consequently the contact element is tightened towards the body to be contacted and thus is particularly reliably electrically connected to the body to be contacted.

In the above embodiments, the elastic portion may form a coating of the contact element or the contact element may be at least partly contained within the elastic material.

The contact element can be combined with a thin, optionally colored film to selectively further advantage the device of the invention or to protect it from the atmosphere. However, the contact element may also be combined with an elastic material to be electrically insulated or included therein.

Elastic materials can be selected within wide limits for specific requirements. The elastic material is preferably an elastomer, in particular a thermoplastic elastomer. As a result, the manufacturing cost of the apparatus of the present invention becomes low. Any elastomer can be used, for example hardened rubber. Thermoplastic elastomers are particularly preferred because they can be easily processed.

In another variant of the embodiment including the elastic portion, the contact element is connected to the radially inner surface of the elastic portion and a band-shaped tightening band tightening around the body to which the device of the present invention is contacted has a radially inner surface of the elastic portion. It is preferably attached in a fixed manner.

The clamp allows the device of the present invention to be tightened around the body to be contacted, the contact element being firmly pressed against the body and the elastic material between the clamp and the contact element being pressed, thereby contacting the body to be contacted. Is deflected towards.

Due to this deflection action, a reliable electrical connection between the contact element and the body to be contacted can be achieved even when the tensioning portion is loosened over time.

In a variant of this embodiment, the tension portion is a metal and the contact element is connected in an electrically conductive manner with the tension portion. In this design, a conductor such as, for example, a grounding cable can be easily connected with an externally accessible clamping part at the assembly position of the device of the invention due to the electrical connection between the clamping part and the contact element, the body being contacted intended Can be grounded.

In another variant, the contact element is a contact element in an assembly position with respect to the body to which the conductor is contacted to make an electrically conductive connection between the conductor to which the conductor is grounded and the body, for example to a terminal locking conductor such as a ground cable. Assembled in a way that can be connected with. The terminal facilitates locking of a conductor, for example a ground cable.

With respect to the embodiment of the base structure and the bracket as a unitary unit, the above-described embodiment has a bore hole in which the contact element constitutes the bracket or extends into the bracket and at least one hole is present in the bracket and at least one thread is formed in the other bracket. The bore holes are opposed to the bore holes in the assembly position, and the contact elements can be crossed by one or more holes in the assembly position by the metal screw, which is preferably electrically conductive, and with each other and for example the ground cable. The threaded bore hole connecting the same conductor and the bracket is connected and thus the bracket is formed by the method of constructing the terminal portion.

The design is carried out in a particularly easy and quick way and can therefore be economically assembled. The conductors are fixed using one or more screws and on the one hand the brackets are screwed together and on the other hand the conductors using the connecting grommet are connected to the brackets in an electrically conductive manner.

In a typical preferred variant of an embodiment comprising an elastic portion, the elastic material is composed of an electrically conductive elastic material, at least partially comprising one or more protrusions constituting the contact protrusion.

Due to the electrical conductivity of the elastic material, the base structure can be composed entirely of elastic material and consequently no metal parts are needed. The above features facilitate the manufacture of the device of the present invention.

Regeneration is also improved because the base structure consists of a single material.

In the above embodiment for achieving electrical conductivity, the cell conductive mass or particles are preferably included in the elastic material. By preferably selecting the electrically conductive mass or particles in the elastic material, the conductivity of the elastic material can be selected within a wide range of limits depending on the specific requirements.

In a variation of this embodiment, the elastic conducting mass or particles are distributed uniformly in the elastic material. In this way the elastic material becomes uniformly conductive. If, for example, the device of the invention has to contact the outer surface of a metal pipe, the surface is held against it at the assembly position and the surface protruding contact projections perpendicular to the remaining surface up to the surface area are contacted.

If, on the one hand, the device of the invention is to be in contact with an exposed coaxial cable outer conductor which recoils quickly against the insulating sheath, the contact projection of the device of the invention is radially projected as long as it is held against the exposed outer conductor at the assembly position. Should be.

In the different variants of the present invention, the contact protrusions or the respective contact protrusions project perpendicularly to the residual surface from the assembly position and rebound against the contacted body portion on the remaining surface of the base structure at the assembly position. Expectations for the electrical conduction segment of the body to be made. Electrically inductive contact with the indentation of the body to be contacted in this way is possible.

In another embodiment, the device of the present invention includes sealing means for sealing a space defined between the bodies that are in contact with the device of the present invention in an assembly position against penetration by air or moisture. This embodiment reliably blocks the interference and subsequent oxidation of the contact area from the outer surface of the body to which air or moisture is in contact.

In a variant of the embodiment, the sealing means comprises an elastic sealing lip at the side of the base structure facing the body being in contact with the assembly position, the lip being spaced apart from each other in the axial direction of the base structure in the circumferential direction of the base structure. Furthermore, the entire length is tight against the outer surface of the body being in contact at the assembly position.

When contacting an elongated and substantially cylindrical body, such as a pipe or cable using a device of the invention comprising a base structure surrounding the body in an assembly position, the embodiment provides for air or moisture entering the contact area. Sealed and shut off reliably.

In another variant of the embodiment comprising an integral base structure with sealing means and a bracket, an elastic seal constructed by facing the sealing element against a sealing element made of an elastic material blocking the surfaces between the surfaces at the bracket surface or at the assembly position. And the sealing surfaces lean tightly to each other or to the sealing element at the assembly position and tightly adjacent to the sealing lip in the circumferential direction of the base structure.

In other embodiments, the contact element or clamp is made of brass or high durability brass or low alloy copper. The electrical conductivity of the material is particularly good and therefore the electrical resistance between the bodies in contact with a conductor such as a ground cable is low.

The invention is illustrated by the various elements shown in the accompanying drawings.

Identical or corresponding elements in the figures are denoted by the same reference numerals.

FIG. 1 shows a flexible base structure 4 in the form of a clamp leaned against the conductive part of the contacting body surrounding the exposed outer conductor 6 of the coaxial cable 8 as in the bush in FIG. 1 in the assembly position. The device 2 of the present invention is shown to include.

In this embodiment, the base structure 4 is integral, opens in the circumferential direction, leans against each other at the assembly position, and is band-shaped metal contact element fitted to the brackets 12, 14 perpendicular to the clamp end. (10).

The bracket 12 comprises a hole, the bracket 14 is not shown but in the assembly position, in the assembly position in the embodiment by a metal screw 18 connecting threaded bore holes and passing through the holes. The conductors shown in the ground cable 20 and in a manner that can be connected to each other are opposed to the holes 16. The base structure 4 also comprises, for example, a portion 22 made of an elastomer, in particular a thermoplastic elastomer.

2 shows that the elastic part 22 constitutes the radially outer surface 24 of the base structure 4 and the contact element 10 is included by the axial edges 26, 28 in the elastic material of the part 22. Shows that.

The sealing lips 30, 32 spaced apart from each other in the axial direction of the base structure 4 are formed by the elastic material of the part 2 on the side surface 92 of the base structure 4. In,-the additional sealing lips 34 and 36 facing the body to be contacted at the assembly position are formed axially outwardly on the sealing lips 30 and 32, respectively.

As not shown in the figure, the sealing lips 30, 32 and also the additional sealing lips 34, 36 also pass substantially through the entire length of the base structure in the circumferential direction and of the device 2 shown in FIG. 1. It is emphasized that there is a tight expectation of the sheath of the coaxial cable 8 in the assembly position.

They seal a defined space at the assembly position of the apparatus 2 of the invention between the coaxial cable 8 and the base structure 4 being contacted defining the contact area 38. Here, an electrically conductive connection between the device 2 of the invention and the outer conductor 6 of the coaxial cable is carried out.

The device 2 of the present invention for carrying out the electrically conductive connection between the outer conductor 6 of the coaxial cable 8 which is in contact with the device 2 of the present invention is a contact projection shown by reference numeral 40 in FIG. Combined with.

As shown in cross section, the contact protrusion is convex with respect to the coaxial cable 8, while in plan view it is substantially circular.

The apparatus 2 of the present invention operates as follows:

In order to effect the electrically conducting connection between the outer conductor 6 of the coaxial cable 8 being brought into contact with the ground cable 20, the device 2 of the invention is located around the exposed area of the coaxial cable 8 and screwed in. It is fixed by 18.

In this process, the base structure 4 has the coaxial cable 8 leaned against the sheath by the remaining surfaces 42 and 44 constituted by the sealing surfaces of the sealing lips 30 and 32.

The contact protrusion 40 projects perpendicularly to the remaining surfaces 42 and 44 at the assembly position in the direction indicated by arrow 46 in FIG. 2, and radially rebounds at the assembly position above the remaining surfaces 42 and 44. Expectations are expected for the outer conductor 6 of the coaxial cable 8. Thus, an electrically conductive connection is made between the contact element 10 and the outer conductor 6.

Since the ground cable 20 is connected to the contact element 10 via a screw 18, an electrically conducting connection is made in this way and the outer conductor 6 is now grounded. The contact protrusion 40 is deformed while the base structure 4 is fixed so as to lean in an elastic manner with respect to the outer conductor 6 of the coaxial cable 8.

In this way an elastic electrical connection is fixed between the ground cable 20 and the outer conductor. Since the contact protrusion 40 is part of the base structure 4, a separate element, for example an adapter, is no longer needed.

This feature simplifies the design of the apparatus 2 of the invention and makes the manufacturing more economical.
