Definitions

  • Inner conductor contact element for right-angle connectors and associated manufacturing method
  • the present invention relates to an inner conductor contact element for an angle connector and a method for producing an inner conductor contact element.
  • an electrical plug connector and an associated electrical mating connector can consequently be a plug, a printed circuit board plug, a built-in plug, a socket, a coupling or an adapter.
  • the term "connector" or “mating connector” used in the context of the invention is representative of all variants.
  • Such a plug-in connection must withstand high mechanical loads, for example remain closed during the entire operation in a defined manner, and maintain reliable electrical contact. Due to the high volume of data that is communicated between the individual electronic devices in the vehicle, an electrical plug connection must be able to handle data transmission with a high transmission bandwidth as a further technical challenge. In addition, the installation space and the weight of the connector must be kept low. Finally, the connector is economical to manufacture in large numbers and easy to assemble.
  • DE 202008 014 409 U1 discloses an angle connector for transmitting a high-frequency electrical signal.
  • the right-angle connector of DE 20 2008 014 409 U1 has two inner conductor contact elements for contacting the inner conductor of the high-frequency cable and the inner conductor of the associated mating connector. These are electrically and mechanically connected to each other within the right-angle connector.
  • the object of the present invention is to provide an inner conductor contact element for an angle connector, with which simple and inexpensive assembly of an angle connector is possible.
  • An inner conductor contact element for an angle connector having a crimping area, which is set up to be connectable to an inner conductor of a cable, an interface area, which is set up to be connectable to an inner conductor contact element of a mating connector that corresponds to the angle connector, and a connection area, which connects the crimping area to the interface area connects, wherein the inner conductor contact element is formed in one piece, wherein the connection area has a first transverse extent and a second transverse extent which is smaller, preferably many times smaller, than the first transverse extent, the connection area being divided by the first transverse extent and a longitudinal extent of the connection area trained plane is angularly shaped.
  • the finding/idea on which the present invention is based is to design a one-piece inner conductor contact element for an angle connector.
  • the inner conductor contact element has three areas that are connected to one another in one piece.
  • a mechanical and electrical connection to the inner conductor of a coaxial cable is possible in a crimping area of the inner conductor contact element, while an interface area of the inner conductor contact element can be connected to the inner conductor of a coaxial mating connector.
  • the crimping area is connected to the interface area via a connecting area of the inner conductor contact element, which is formed in an angle.
  • an angularly shaped connection area is to be understood as meaning a connection area which comprises two elongate partial areas which each have a common end and are therefore connected to one another via the common end.
  • the two elongate sections are oriented at an angle to one another with respect to their longitudinal extent relative to the common end.
  • the angle is greater than 0° and less than 180°, preferably greater than 45° and less than 135°, particularly preferably greater than 85° and less than 95° and at best 90°. Due to the angular shape of the connection area, the crimping area is oriented at an angle to the interface area, and a one-piece realization of an inner conductor contact element for an angle plug connector is therefore advantageously possible.
  • the crimping area of the inner conductor contact element enables a crimp connection to be formed between the inner conductor contact element of the right-angle connector and an inner conductor of a cable, preferably a coaxial cable.
  • a crimp connection is a non-releasable electrical connection between at least one inner conductor, preferably a single inner conductor, and a crimp area designed as a crimp contact.
  • the crimp contact which is preferably embodied as a crimp sleeve, can have different crimp cross-sectional profiles, for example a circular profile in the case of the so-called Runderimp, a B-shaped profile in the case of the so-called B-crimp, an elliptical profile and so on.
  • the interface area of the inner conductor contact element is used for electrical contacting and mechanical connection with the inner conductor contact element of the associated mating connector.
  • it can be shaped like a pin or socket in order to contact a socket-shaped or pin-shaped inner conductor contact element of a mating connector.
  • the interface area can be stamped out of a one-piece plate-shaped metal body and formed into the respective end shape in a subsequent bending process.
  • connection area of the inner conductor contact element is that area of the one-piece inner conductor contact element which is arranged between the crimping area and the interface area and mechanically and electrically connects the crimping area to the interface area in one piece.
  • the cross section of the crimping area and the interface area is preferably adapted to the cross section of the connection area in the transition between the crimping area and the connection area and between the connection area and the interface area.
  • the elongate partial areas of the angular connecting area preferably merge into one another in the form of a curve or an arc.
  • a continuous longitudinal course with a constant cross section from the crimping area over the connection area to the interface area is thus realized, which enables a constant impedance course from the crimping area over the longitudinal extent of the connection area to the interface area.
  • the one-piece inner conductor contact element can be produced from a plate-shaped metal body, ie from a metal sheet, in a first production step by means of a forming process, preferably a stamping process.
  • a metallic material with a good mechanical workability for example brass, copper beryllium or the like.
  • the metallic base material of the inner conductor contact element is preferably additionally coated with a coating material with good electrical conductivity, for example gold, silver or the like.
  • the longitudinal extent of the interface area and the longitudinal extent of the crimping area are oriented orthogonally to one another. This is realized by an angularly shaped connecting area, the elongated partial areas of which are oriented at an angle of 90° to one another.
  • connection area is in the form of a strip.
  • the band-shaped connection area has an angular formation in a plane defined by the longitudinal extent and by the larger transverse extent, i. H. the first transverse extent of the band-shaped connecting area is formed.
  • the angular shape of the connection area is designed to be only planar.
  • a planar formation i. H. a plate-like formation of a three-dimensional body is characterized by a main extension of the body in a single plane.
  • a planar or plate-like configuration has no curvature, bend, buckling, or the like.
  • the angular formation of the connecting area can thus be formed solely in a plane which is formed by the longitudinal extent and the larger transverse extent, i.e. the first transverse extent, of the connecting area.
  • the connection area of the inner conductor contact element can be realized solely by a stamping process. In this case, the bending steps can be limited solely to the shaping of the interface area and the crimping area.
  • connection area In the case of an angular shape of the connecting area in a plane formed in the connecting area by its longitudinal extent and its smaller transverse extent, ie the second transverse extent, there is no plate-like formation and no planar structure, but rather a curved structure. With such an angular formation of the connection area, a bending process is required in addition to the stamping process. Since the manufacturing accuracy when stamping is better by a factor of three to five compared to bending according to the current state of technology, a higher precision of the inner conductor contact element and thus also a more precise arrangement and shaping to the outer conductor contact element of the coaxial angle connector can be realized with a single planar design of the angled connection area . The impedance profile in the critical connection area of the inner conductor contact element can thus be additionally optimized.
  • connection area of the inner conductor contact element is produced in a way that is limited solely to a stamping process, crack formation that typically occurs during the bending process and subsequent bending back that may occur as a result of relaxation can be avoided.
  • the outer conductor contact element is adapted to the inner conductor contact element with regard to an optimized impedance matching
  • a large area of the E-field is oriented parallel along the longitudinal extension of the connection area in a single planar design of the angular connection area.
  • only a small area of the E field is oriented parallel along the longitudinal extent of the connection area.
  • a single planar design of the angled connection area also brings about an improvement in the impedance matching along the longitudinal extension of the connection area.
  • connection area in a plane formed by the longitudinal extent and the greater transverse extent of the connection area, a non-planar design of the connection area is also conceivable within the scope of the invention.
  • a U-shaped or cylindrical cross-sectional profile of the connection area for example, can be realized by an additional bending process.
  • the crimping area of the inner conductor contact element preferably has a support area and at least one crimping wing.
  • the contact area is that area of the crimping area or of the crimping sleeve that rests on the anvil belonging to the crimping tool.
  • the profile of the support area thus corresponds to the inner profile of the anvil and typically has a planar or approximately planar profile.
  • Each individual crimping wing of the crimping area or the crimping sleeve is connected to the support area.
  • the connection between the individual crimping wing and the contact area takes place on the side of the contact area, i. H. each at a lateral end of the support area, over a longitudinal extension of the support area.
  • each individual crimping wing is bent during the crimping process in such a way that the contact area and the at least one crimping wing together form the strands of the inner cable conductor encase gas-tight and press and thus a secure mechanical and electrical connection between the cable inner conductor and the inner conductor contact element is made.
  • the contact area of the crimping area is preferably aligned orthogonally to the connection area, i.e. the area vector of the planar contact area of the crimping area is oriented perpendicular to the area vector of the planar connection area.
  • a crimping area is formed, which enables a symmetrical insertion and positioning of the inner conductor contact element in the insulator element of the right-angle connector for each crimp sleeve profile used.
  • This symmetrical alignment of the crimping area advantageously prevents tilting of the inner conductor contact element in the insulator element and thus an asymmetrical end position of the inner conductor contact element in the insulator element. This technical measure also improves impedance matching within the coaxial right-angle connector.
  • the contact area of the crimping area can be oriented in the same direction as the connection area, i.e. the area vector of the planar contact area of the crimping area and the area vector of the planar connection area have the same orientation. Any other technically sensible orientation between the contact area of the crimping area and the connection area is also conceivable.
  • the crimping area is to be connected to the connection area via its contact area and at the same time the contact area is to be aligned orthogonally to the connection area.
  • the support area preferably has an axial extension that is laterally attached to the connection area, d. H. at a lateral end of the connection area.
  • the axial extension of the support area is only laterally connected to an axial end area of the connection area in order to make the connection between the connection area and the crimping area as short as possible.
  • the axial extension of the bearing area is bent at right angles to the connection area.
  • the inner conductor contact element is inserted into the insulator element of the right-angle connector with the aid of a joining or pressing tool, which exerts sufficient press-in pressure on the inner conductor contact element during joining.
  • the pressing tool exerts a symmetrical press-in pressure on the inner conductor contact element in order to insert the inner conductor contact element symmetrically, i.e. without tilting to the joining direction, into the recesses of the insulator element.
  • symmetrical bearing surfaces for the pressing tool are to be formed on the inner conductor contact element to be joined. Due to the angled geometry of the inner conductor contact element, symmetrical contact surfaces for the pressing tool must be provided in each of the two leg-shaped sections of the inner conductor contact element:
  • the axial extension of the a flange-shaped area connected at right angles to the contact area belonging to the crimp sleeve.
  • the inner conductor contact element has a U-shaped cross-sectional profile over the longitudinal extension of the axial extension of the contact area belonging to the crimp sleeve together with the flange-shaped area attached at the side and the connection area also attached at the side.
  • the end faces of the flange-shaped area and the connecting area together form symmetrical bearing surfaces for a pressing tool.
  • the interface area is preferably designed in the form of a socket in its longitudinal extension.
  • the socket shape of the interface area is realized by bending after the stamping process.
  • the end face of the socket-shaped interface area adjoining the connection area forms a symmetrical support surface for a pressing tool.
  • a symmetrical insertion and positioning of the inner conductor contact element in the insulator element is guaranteed by a correspondingly shaped pressing tool via the crimp-side and the interface-side symmetrical bearing surfaces.
  • the outer diameter is tapered as the first form of a technical fixation measure.
  • the taper is preferably designed conically, but can also be realized in a concave or convex manner.
  • the taper is preferably formed in a partial section of the longitudinal extension. However, a narrowing over the entire longitudinal extent or several narrowings in individual sections of the longitudinal extent of the interface area are also conceivable.
  • the inside diameter of the insulator element also has a taper, preferably a taper with the same taper profile as the taper in the inner conductor contact element.
  • a radially elastic latching means is provided on the outer surface of the interface area, which latches into a corresponding counter-latching means of the insulator element during the joining process of the inner conductor contact element.
  • a detent, a detent hook, a spring arm, a snap hook or the like can be used as the detent means.
  • a locking recess, a snap-in receptacle or the like can thus serve as the corresponding counter-locking means.
  • the latching means typically has a stop surface which is directed counter to the joining direction and is supported on an inner wall of the counter-latching means in the latched state.
  • the inner conductor contact element is thus blocked in its axial freedom of movement counter to the joining direction when the latching means and counter-latching means are in the latched state. That on Latching means formed on the inner conductor contact element thus acts together with the counter-latching means of the insulator element as a “reverse stop” or “reverse stop”.
  • a combination of tapering and latching means is preferably formed on the inner conductor contact element in order to achieve a form-fitting fixation of the inner conductor contact element within the insulator element and thus a fixation in both axial directions.
  • the inner conductor contact element is fixed in place in the leg-shaped section of the angled plug connector that belongs to the interface area.
  • At least one web-shaped section is formed on an inner wall of the insulator element, which is directed radially inward and extends in the direction of the longitudinal extension of the interface area of the inner conductor contact element, i. H. extends in the joining direction of the inner conductor contact element.
  • this at least one web-shaped section of the insulator element is pressed with an outwardly directed wall in the connection area of the inner conductor contact element. This results in a non-positive connection between the inner conductor contact element and the insulator element.
  • the non-positive connection between the inner conductor contact element and the insulator element is preferably in a leg-shaped section of the right-angle connector that belongs to the crimping area of the inner conductor contact element, i. H. implemented in a section of the connection area of the inner conductor contact element adjoining the crimping area.
  • the web-shaped section on the inner wall of the insulator element can also be referred to as a crushing rib due to its compression with the inner conductor contact element.
  • Two web-shaped sections are preferably formed in the inner wall of the insulator element, which are each arranged opposite one another and are each non-positively connected to the connecting region or the flange-shaped region of the inner conductor contact element formed opposite. In this way, a symmetrical fixing and alignment of the inner conductor contact element is realized in the leg-shaped section of the right-angle connector that belongs to the crimping area.
  • a plurality of bar-shaped sections or a plurality of pairs of bar-shaped sections can also be provided to improve the non-positive fixing.
  • At least one recess and/or at least one elevation is formed in such a way that it can be latched with a complementary elevation or recess in an insulator element belonging to the angle connector.
  • a recess or such an elevation can be produced, for example, in an embossing process that follows the stamping process.
  • the individual recess or the individual Elevation is formed in each case in such a way that it enables the inner conductor contact element to be fixed, preferably secured against rotation, in the insulator element.
  • Such a recess or such an elevation can have, for example, a triangular, quadrangular or polygonal cross-sectional profile.
  • Angular or multi-leg cross-sectional profiles are also conceivable. Tilting of the inner conductor contact element within the insulator element of the right-angle connector about an axis of rotation, which is oriented perpendicularly to the plane of the two leg-shaped sections of the right-angle connector, can thus advantageously be prevented.
  • the section of the angled connector in which the angled connection area of the inner conductor contact element is positioned must be improved with regard to the impedance curve.
  • another angled area is connected to the angled connection area, preferably via a connecting web.
  • the further angularly shaped area preferably corresponds to the angularly shaped connecting area and is preferably oriented parallel to the angularly shaped connecting area and arranged at a distance from it over the length of the connecting web.
