Definitions

  • the invention relates to a contact socket for transmitting electrical energy through detachable contacting with a contact pin.
  • Plug connections, contacting elements, pole connectors, sockets, etc. are used in a wide variety of configurations and variants to make contact or produce detachable electrically conductive connections.
  • contact systems have been developed which are based on round contact geometries to accommodate a contact pin and whose starting material consists of a flat contact grid that is brought into the round contact geometry with hyperbolic twist.
  • These contact systems which have become known as RADSOK, are characterized by robust and high-density contact production as a result of the considerable contact area with the respective contact pin.
  • inwardly directed lamina geometries are known, the lamina contact grid of which is aligned radially symmetrically.
  • contact geometries which are preferably used as high-current contact sockets, are consequently known as radial contact sockets or hyperbolic contact sockets.
  • RADSOK contact systems of the aforementioned type are received in connector sleeves via their generally cylindrical outer contours and establish contact on the outside via the cylindrical surfaces.
  • DE 102007 051 266 B4 is based on the basic idea of providing a single connector socket sleeve that is designed in such a way that different lamellar contact cages in the form of RADSOK contact sockets can be accommodated, which come to rest flat on the inside of the contact sleeve.
  • the subject of the invention here is the coupling, connection, contacting of the cylindrical lamellar cage “on the fly” within the receiving connector socket sleeve, in that only one of the respective end-side collars is fixed in the socket, for example by a press fit.
  • An electrical connector socket is provided, comprising a cylindrical socket sleeve, which is designed with a receiving space in which a cylindrical lamellar cage with a large number of parallel running contact lamellas is inserted, wherein the lamellar cage has a first and second peripheral web at the end, between which the contact lamellae run.
  • the lamellar cage is fixed at one end at least axially and preferably also non-rotatably in the bushing sleeve and thereby clamped or fastened, and at the other opposite end there is an axial slide bearing that can be rotated at least by a certain angle of rotation relative to the bushing sleeve.
  • the laminated cage is preferably fastened with its one collar web to the inner wall of the bush sleeve by means of fastening means on the sleeve side.
  • plug connections and their contacting elements which are often made up of one or more pairs consisting of a plug contact pin and plug contact socket, for example mechanical loads, vibrations, impacts, and aging effects.
  • Considerable temperature influences caused by environmental conditions or as a result of self-heating caused by the flowing electrical power and the inherent resistance of the live parts are also possible.
  • the contact force - more precisely: the contact normal force - is as high and constant as possible in order to press the contact partners, usually formed by contact pin and contact socket for their electrical contacting, together on their contact surfaces.
  • the contact sockets available in the prior art such as the mentioned RADSOK sockets or their plug-in contact partners, the plug-in contact pins, both plastic shaping processes such as stamping, rolling and suitable materials with resilient properties are used in order to generate the desired spring effects through restoring forces that are used in order to preferably generate elastic contact pressure forces of the contact partners on their contact surfaces.
  • the performance of the plug-in contact connection is limited by the effects of temperature, because higher temperatures cause a loss of spring force as a result of relaxation processes, material creep and internal stress reduction. This is especially true for copper and Copper alloys, since copper, in addition to its generally low elasticity, becomes "soft" above all at low temperatures.
  • plug-in contact partners are designed in this way and made of materials such as spring steel, it is possible to generate very high normal contact forces that reliably press the contact surfaces of the plug-in contact partners together, but assembly problems often arise because plugging the contact partners together requires high plug-in forces that make assembly difficult or require the use of tools.
  • female contact partners for plug-in contact pins consisting of a rigid and low-deformation outer sleeve and a lamellar cage accommodated in it.
  • the lamellar cage is the element with the elastic deformation properties and has a correspondingly filigree and delicate structure.
  • Solutions of this type require at least three contact partner components in the form of a plug contact pin as a male plug contact partner and the combination consisting of an outer sleeve with a laminar cage as a female plug contact partner.
  • These constructions are known as RADSOK contact systems and can be realized, for example, as radial lamellar contacts or hyperbolic lamellar contacts.
  • US Pat. No. 4,657,335 A discloses additional fastening elements in the form of rings, which are slipped over the respective ends of the outer sleeve, to fix the lamellar cage in the outer sleeve.
  • Fastening solutions with in- or rear grips are implemented, for example, with grip tongues.
  • DE 10 2011 105 821 B4 shows a cylindrical outer sleeve with a receiving space in which a hyperbolically rotated laminar cage is fitted.
  • the outer sleeve has a first and second end face with openings.
  • the lamellar cage is equipped with corresponding connection tongues in such a way that the tongues on the first and second end face of the outer sleeve can be positively connected to the outer sleeve.
  • the object of the invention is to further develop the existing contacting solutions with the contact normal forces of the contact partners increased by elastically prestressed spring elements, to at least partially reduce the existing disadvantages and to simplify assembly.
  • the invention proposes a contact socket in the form of a spiral sleeve with female property for a contact plug with male property, which increases the contact normal force through high elastic prestress and also has particularly pronounced elasticity properties through high deformability.
  • the basic idea of the invention is to realize the outer sleeve and the lamellar cage as one component in an integrative manner and to combine the at least partially ambivalent properties consisting of elasticity properties to reduce assembly and insertion forces and high elastic spring preload to support high contact normal forces through constructive design.
  • the spiral sleeve according to the invention is a preferably one-piece combination of an element forming the outer sleeve, combined with a spiral extending inside the outer sleeve.
  • the outer sleeve is not designed as a closed tubular cross section, but rather as an open tubular cross section.
  • the strip-shaped semi-finished material from which the spiral sleeve is formed is guided into the interior of the outer sleeve in the region of the open part, seen from the cross-sectional view, and has a cross-sectional geometry similar to a spiral.
  • the spiral sleeve is produced by stamping and rolling
  • the first section of the semi-finished material in strip form can be deformed into a spiral and then its second section can be rolled into the outer sleeve, which accommodates the spiral inside.
  • the outer sleeve as the first integrative element of the spiral sleeve implements the support and support function to increase the preload and thus increase the contact normal force of the female contact partner in the plug connection.
  • the spiral as the second integrative element of the spiral sleeve realizes the reduction of the Monday and
  • the spiral thus acts as a practical spring element integrated into the spiral sleeve, which represents the female contact socket in the plug connection.
  • the spiral in the interior of the spiral sleeve is formed in its cross section by a plurality of radii of curvature with at least partially changing signs and is shaped in such a way that a contact plug can be inserted on the inside of the spiral. It is provided that contact is made with the contact plug on at least three contact surfaces of the spiral with its wave-shaped sections. The contact surfaces result from the shape of the spiral and are linear in some areas, extending in the axial direction of the spiral sleeve.
  • the contact plug, contact pin must be matched to this in terms of its dimensions, i.e.
  • the contact pin With the proposed spiral sleeve there are considerable advantages over the known prior art. With the spiral sleeve and its integrative concept, the contact partners are only formed from the spiral sleeve and contact pin, so that production, assembly, storage and handling are very economical. The spiral sleeve can also be produced economically by stamping and rolling and is simple in its one-piece construction.
  • the contact pin does not necessarily have to be inserted centrally into the spiral sleeve with a narrow tolerance, because the spiral with its wave-shaped sections can compensate for an eccentric offset very well and ensure that the plug contact partners are centered relative to one another. Cables and electrical lines can be fixed to the spiral sleeve in a simple and proven manner, for example by crimping or welding.
  • the contact normal force is to be further increased, particularly in the event of temperature changes due to the transmission of electrical energy, it is possible to combine and contact the spiral sleeve according to the invention with a contact plug, which deforms as a result of the temperature change and causes the change in the contact normal force between the contact partners as a result of the deformation.

If the recesses A are arranged in the contact areas 52 of the spiral 50, the contact normal forces are influenced on the one hand and the surface pressure of the contact surfaces of the spiral 50 and contact pin 20 lying against one another are influenced on the other hand, as a result of the recesses A reducing the contact surface and thus the surface pressure on the remaining area is increased.
