Definitions
- the invention relates to a clamping device for contacting and holding the inner conductor of a coaxial cable in a coaxial cable connecting device according to the preamble of claim 1.
- Clamping devices of this type are required for the various connection technologies for HF transmission, in particular in antenna sockets and HF device connections.
- High demands are made on contacting and holding the inner conductor of the coaxial cable in order to ensure the necessary safe and stable conductive connection between the inner conductor and the further connection contact with regard to the transmission of high and very high frequencies.
- a clamping device according to the preamble of claim 1 is described within an antenna socket in the earlier patent application P 35 30721.8-34.
- This clamping device has, as the lower clamping part, an abutment made of insulating material, on the upper side of which a cross-section extends to the inner conductor longitudinal axis Is held wire end that extends to the other electrical components.
- the upper clamp consists of a clamp part screwable against the abutment with a pressure piece made of insulating material resting on the abutment.
- the wire end forming the connection contact lies firmly on the top of the abutment.
- the upper clamping part and the pressure piece are also held rigidly on the associated screw.
- Other known clamping devices also always have connection contacts and rigid clamping parts which are held firmly on the respective associated support.
- connection contact is designed as an elongated contact element running transversely to the longitudinal axis of the inner conductor on the abutment, it is particularly advantageous if, in a further embodiment of the invention, the contact element is resiliently held relative to the abutment in such a way that its surface contacting the cable inner conductor is in a non-jamming rest position relative to the The surface of the abutment protrudes.
- the desired resilient reserve for the clamping pressure is thus generated via the contact element itself.
- the contact element consists of a wire end held on the abutment
- the wire end is held in the abutment so that it can move freely relative to an associated groove.
- this results in a very simple design of the abutment with the contact element.
- the wire end can be deformed into a roof-shaped cross section.
- the inner conductor is from its elongated during the clamping process due to the location and design of the contact element Form of origin deformed against its longitudinal axis, and this deformation is always a resilient reserve available, so that a high level of security and a long service life for contacting and holding is achieved with very simple means.
- the features of claim 5 reflect a particularly advantageous embodiment for constructive and functional reasons.
- the end of the wire can be deformed and produced in the desired manner in a very simple or a few simple operations and assembled in the pocket which can also be formed in the abutment in a likewise simple manner.
- the features of claim 6 also lead to an embodiment that is particularly favorable in terms of both construction and function.
- the clamping device has an upper clamping part which can be screwed firmly against the abutment, that the upper clamping part itself or on its screw is resiliently mounted with respect to the abutment.
- the desired resilient reserve can be introduced by simply inserting suitable springs on the support of the upper clamping part or between the upper clamping part and screw.
- the pressure piece on the upper clamping part can be held resiliently with respect to the abutment.
- a suitable resilient intermediate layer also in the form of a leaf or correspondingly shaped other metal spring, can be arranged between the pressure piece made of insulating material and the rest of the upper clamping part.
- Fig. 1 is a perspective view of the essential parts of the clamping device for explanation and
- Fig. 2 is a diagrammatic representation of the wire end used therein with further connecting wire.
- the clamping device shown in the drawing for contacting and holding the inner conductor of a coaxial cable can be used in particular in an antenna socket but also in other coaxial cable connecting devices, as are required when connecting coaxial cables to devices of high-frequency technology.
- the clamping device serves to contact and hold the inner conductor 1 of a coaxial cable 2. It has a lower clamping part in the form of an abutment 3 made of insulating material and an upper clamping part 4.
- the upper clamping part is provided on its underside performing the clamping process with a pressure piece 5 made of insulating material.
- the upper clamping part 4 with the exception of the pressure piece 5 can also consist of a solid insulating material or, in the case of corresponding stresses, of a metallic material.
- the upper clamping part 4 can be screwed with the aid of a screw 6, which can be screwed into a suitable lower device part carrying the abutment 3, against the inner conductor 1 and the abutment 3 introduced in the manner shown, via the pressure piece 5, clamping part 4 and pressure piece 5 can also be made in one piece from the same insulating material.
- the abutment 3 has one facing the inner conductor 1 roof-shaped top 7.
- a groove 8 extending transversely to the inner conductor 1 is formed in the apex of the upper side 7.
- the connection contact is held on the abutment 3, here as an elongated contact element in the form of a wire end 9 running transversely to the longitudinal axis of the inner conductor on the abutment 3 the respective electrical components or to a connection plate or the like.
- the wire end 9 is resiliently held above the groove 8 with respect to the abutment 3 in such a way that its surface contacting the cable inner conductor projects in the illustrated non-jamming rest bearing opposite the upper side 7 of the abutment 3.
- the wire end 9 on its further wire section 10 guided in the abutment 3 is deformed into a cross-sectional widening 11, pressed here into a flat piece, and this widening of the cross-section 11 is in an associated pocket 12 in the abutment 3 introduced.
- the wire end 9 is deformed into a roof-shaped cross section, as the drawing shows.
- Abutment 7 screwed tight, so the pressure piece 5 presses the inner conductor 1 on the one hand on the wire end 9 and on the other hand on the roof-shaped top 7 of the abutment.
- the wire end 9 is deflected resiliently and therefore provides a resilient reserve force for contacting and holding the inner conductor 1, which due to the metallic design of the wire end 9 also at below different forces and even with temperature-related changes in the abutment 3 or the pressure piece 5 is retained.
- the wire end 9 can escape into the groove 8 in the top 7 of the abutment 3.
- the inner conductor 1 is deformed accordingly by its complementary roof-shaped pressure piece 5 and the roof-shaped upper side 7 of the abutment 3 against its longitudinal direction, that is, it is bent here in order to achieve a secure holding of the inner conductor 1, in particular against axial forces.
- the upper clamping part 4 it is also possible to resiliently support the upper clamping part 4 with respect to its support on the corresponding device or to provide a spring between the screw 6 and the upper clamping part 4 in order to achieve the desired spring reserve. It is also possible to insert a resilient component between the pressure piece 5 and the corresponding facing surface of the upper clamping part 4.
- the desired additional spring reserve is achieved via metal components, so that temperature or aging-related changes in the insulating materials are always compensated for by the spring reserves introduced.
