Definitions

  • the invention relates to a shielded ready-to-use or assembled single-pole, multi-pole or coaxial connector according to the features of the preamble of claim 1.
  • Such shielded connectors are known for example from DE 103 02 710, DE 103 02 711 or DE 103 23 612.
  • contacts that are relatively stationary, preferably rotatable and / or axially displaceable contacts, in particular sliding contacts, which can either always be closed or also released during operation. It is necessary to generate an appropriate contact force between the contact points, the amount of which in turn is decisive for the size of the resulting metallic and quasi-metallic contact surfaces, and thus for the amount of contact resistance.
  • Another solution is to design one of the parts so that it has bending lamellae produced from a tubular extension by radial slits has flying ends, and these ends with a defined undersize resiliently abut a corresponding lateral surface of the other part.
  • Bending lamellae which are produced from a tubular profile by radial slitting, have the shape of ring segments in cross section.
  • Such springs have an increased axial area torque in comparison to bending lamellae with a rectangular cross-section with the same thickness and the same cross-sectional area and thus, with a given spring length and material, a correspondingly higher spring stiffness. This difference is all the more serious, the more pronounced the curvature of such ring segments is relative to their width.
  • you design such slats accordingly narrow in order to achieve a stiffness similar to that of comparable rectangular slats a high degree of transverse stability is lost in the direction of rotation or movement.
  • the springs become very susceptible to injury at their flying ends " during transport, assembly and operation, on the other hand they tend to stick-slip behavior.”
  • ring segment slats have a smaller permissible spring travel than rectangular slats Since the adjustment of the spring travel is inevitably connected to a dimension or tolerance chain, this means that the dimensional accuracy of the corresponding parts must be increased.
  • the behavior of a closed tube profile, which is divided on one side by slits is contrary to this requirement Since this process exposes internal tensions, the ends of the exposed lamella, on which the contact surfaces are expediently located, have the greatest dimensional and shape tolerances.
  • the invention is therefore based on the object of providing a shielded connector which meets the requirements described.
  • a shielded round plug or a shielded round socket also called round bushing
  • whose preferably metallic housing contains at least one union nut and union screw or two corresponding union nuts or two corresponding union screws, which perform fastening functions in opposite directions by means of threads, bayonets, locking elements, overmolding or overmolding geometry and the like.
  • these parts which are relative to one another, preferably rotatable and / or displaceable, must be designed on the one hand in such a way that in the assembled state they are impermeable to the outside from the electromagnetic radiation, that is to say they have no open gaps on the side.
  • components of the plug or socket shield which in turn can be connected to the respective cable shield at another point, they must make reliable electrical contact with one another.
  • the stick-slip phenomena mentioned above should be avoided with reasonable effort.
  • annular spring system comprising at least one, preferably at least two, ring segment lamellae is arranged on the union nut or on the union screw of the plug or socket (socket), which has a closed spring ring at the end, which connects the ring segment lamellae to one another at their ends.
  • the invention relates essentially to the part shown in FIGS. 1 and 2 with the reference number 1.
  • it is a union nut with a tubular extension which has at least one, preferably at least two openings preferably produced by milling. Alternatively, these openings can also be created by other manufacturing processes such as polygon turning, laser cutting, drilling, shaping, etching and the like.
  • This forms a one-piece spring system, which essentially consists of at least one, preferably at least two, preferably symmetrically arranged ring segment lamellae 1.1 (which can also be referred to as ring segment webs) and the closed spring ring 1.2 exists that connects these lamella (s) together at their resilient ends.
  • this system can, but does not have to, have at least one, preferably at least two projections 1.3, in turn with a contact surface 1.3.1 and the transition surfaces 1.3.2 and 1.3.3.
  • the position of these projections 1.3 should preferably be provided along the ring segment lamellae 1.1, so that no additional work step would be required for this. Solutions where this projection or these projections are / are provided only on or also on the closed spring ring 1.2 are of course also conceivable.
  • a system of parallel spiral springs is formed from the ring segment lamella 1.1 converging here or also from the partial sections of this ring segment lamella and the associated partial sections of the spring washer 1.2, according to which the sum of the stiffnesses of these sections acts on each of the contact surfaces 1.3.1.
  • transition surfaces 1.3.2 and 1.3.3 of the protrusions 1.3 can have an angle of inclination “beta” or “gamma” corresponding to the respective application with respect to the longitudinal axis, for example to make assembly easier or to be hooked into a corresponding circumferential groove in part 2 of FIG. 1 allow, whereby the parts would form a subassembly.
  • the side surfaces of the ring segment lamella 1.1 resulting from the above-mentioned openings, they can, as shown for example in FIGS. 1 and 2, have an axially parallel orientation over the longitudinal extension of the lamellae. However, they can also have an oblique, an arc-shaped or a combination of these options.
  • the cross sections of the ring segment lamellae 1.1 and of the closed spring ring 1.2 along their respective longitudinal spring axes can, on the one hand, be made constant, depending on the shape of the inner and outer lateral surface delimiting them, on the other hand also continuously or abruptly variable.
  • FIG. 2 also shows that the ring spring system has a main diameter d2 in the area of the ring segment lamella 1.1 and a diameter d1 in the area of the projections 1.3.
  • the thickness of the projections 1.3 thus results from the difference between d1 and d2.
  • the finished part 1 is shown at the bottom right in FIG. 2 as a component of the connector (other components or assemblies of the connector are not shown for the sake of clarity), here with three ring segment lamellae (although fewer or more than three ring segment lamellae can also be present) ,
  • This part 1 has a roughened for better handling when screwing or fastening with a corresponding part
  • the second part 2 is pushed onto the ring spring system of the first part 1 with little effort and is rotatably fixed in position there. The situation shown in FIG. 1 is thus realized.
  • FIG. 3 shows a spring cage 3 working according to the principle described above, which could serve, for example, as an intermediate contact between an outer and an inner mandrel.
  • the spring cage 3 can also be arranged in a fixed position, displaceable and / or rotatable on the union nut or the union screw.
  • the spring cage 3 has at least one, preferably at least two, preferably symmetrically arranged slats 3.1, which are connected on both sides via closed spring washers 3.2 and 3.3. They have inward and / or outward projections 3.4 and 3.5.
  • the number, position and also alignment of these individual projections along the lamellae 3.1 and / or the spring washers 3.2 and 3.3 can of course be arbitrary to suit the respective application.
  • Such a part has a substantially higher dimensional or tolerance quality compared to the punch bending or punching roll spring baskets already used in practice, in which the lamella connections corresponding to the spring washers 3.2 and 3.3 are open at at least one point.
  • spring baskets are also the more economical solution in applications in which corresponding punching tools would not pay off due to the number of pieces.
  • a multi-level spring cage 4 is also shown as an example. This has slats 4.1, 4.2 and 4.3 connected via closed spring washers 4.4, 4.5, 4.6 and 4.7, the projections 4.8, 4.9 and 4.10 pointing inwards and / or outwards. These projections can of course also be arranged or only along the spring washers 4.4, 4.5, 4.6 and 4.7.
  • Such a spring cage 4 can serve as a multi-digit contact element, the number and position of the lamellae, spring washers and projections can in principle be arbitrary according to the application and the orientation of the individual projections is opposite to the surface to be contacted.
  • the second part 2, or the parts or assembly (s) corresponding to part 2 is / are attached to the first part 1, on which the spring cage 3 or 4 designed as a ring spring system is fixed, fixed, displaceable and / or rotatable, with little force is fixed in position, rotatable and / or displaceable and thus releasably or preferably - if necessary with the help of further parts not shown here - not releasably connected (plugged together).
  • Shielded connectors that is to say a circular connector or a corresponding circular socket in which the ring spring system according to the invention can be used, are known for example from DE 103 02 710, DE 103 02 711 or DE 103 23 612. It is important to make electrical contact with the ring spring system between the two (rotatable) parts (union nut, union screw) that can be moved relative to each other for shielding purposes. This state of the art also shows from which founder the connector is shielded. Alternatively, the invention can also be used with connectors that already . are ready-made.
