Definitions

  • the invention relates to an electrical connector according to the preamble of claim 1.
  • the energy transfer as an electrical current between generators and consumers usually takes place by means of electrically conductive lines.
  • electrically conductive lines In particular when transmitting high currents in electrically conductive connections, the volume, contact and contact resistance has a decisive influence on the efficiency, performance and operational safety of electrotechnical systems and devices.
  • these lines there are usually numerous interfaces, usually also releasable connections in the form of plug contacts, plug connectors and plug devices.
  • the contact resistance plays an important role, particularly in the case of high electrical currents. This contact resistance was mainly composed of volume and contact resistance, with the contact resistance still being the largest bottleneck in power transmission.
  • a known solution is also a conical connection, which is subject to play when inserted axially, but this does not guarantee the uniform pressing of the two conical outer surfaces of the pin and the socket.
  • DE102013018065A1 explains a technique which allows a contact pin to be inserted into a contact socket by means of a combination of two springs without plug-in forces.
  • the electrical connection only arises when a compression spring spreads a contact spring or individual contact spring rings with its axial force and the compression of the compression spring associated therewith. This increases their outer diameter and makes contact of the contact spring with the inner wall of the contact socket. In this way, a contact connection between the contact pin and the contact socket is produced via the contact lines of the contact spring to the outside and a second contact line to the contact pin inwards.
  • This multi-level contacting is it also depends on the dimensional accuracy of the contact spring, compression spring and in particular on burr-free spring ends, which would prevent contact with circumferential lines and can cause damage to the contact surfaces described above.
  • a connector is created in which the above. Disadvantages are eliminated and at the same time the lowest possible contact resistance and, as a result, also a small contact resistance is achieved by a single, long as possible, closed contact line.
  • the aim is to connect electrical conductors as simply as possible using an electrical connector with the lowest possible insertion force, ideally zero, and the lowest possible contact resistance.
  • the manufacture and assembly should be as simple as possible and be carried out using resources that conserve resources.
  • FIG. 1 shows a longitudinal section through a contact socket and a separate contact pin
  • FIG. 2 shows a longitudinal section through the contact socket and contact pin of FIG. 1, which are in the inserted state.
  • electrically conductive contact lines 11 are shown which, when axially pressed, produce an electrically conductive, closed ring line on at least one side of the socket-plug connection.
  • socket and pin can work together as well as independently of each other.
  • Contact socket and contact pin have no resilient function and are therefore very simple from all electrically conductive, preferably deformable materials such as copper, aluminum, brass and. a. getting produced.
  • a closed contact line is created e.g. between the socket-side ko nisch formed surface 3 and the pin-side arcuate Kan te 6 by axial loading, as an inner, closed ring line contact.
  • the closed ring-shaped contact line is generated by the contact on the pin-side conical surface 4 and the socket-side bo-shaped edge 5 by axial loading and is referred to here as the outer ring line contact.
  • the contacting via the ring line contacts 4 and 5 promises better power transmission since a somewhat longer contact line is created here.
  • the second ring line contact on 3 and 6 can be used as a safety contact, for example due to precise manufacture and corresponding tolerance, if, for example, in the case of a Overloading or deformation of the outer socket ring line.
  • An axial pressure creates a multiple contact pressure on the conical contact surface, depending on the pitch of the respective cone and the radius of the arcuate edge, so that the best possible contact resistance can be produced here.
  • An electrical conductivity of K (Kappa) 60 can be achieved here, which is technically unique for connectors.
  • the axial movement of the contact pin 1 in the contact socket 2 can also be determined and adapted by the slope on the conical contact surfaces and the respective radius of the arcuate edge. In this way there is an adjustable pressure force on the closed contact lines, which is sufficient to achieve an excellent contact resistance of less than 0.1 mOhm.
  • the invention describes how the ring line contact can be mounted in order to achieve a high contact force and thereby a low contact resistance.
  • the contact pin 1 is inserted into a contact socket 2 without plug-in force and is centered and guided even without a housing, both through the outer wall of the pin and over the inner wall of the sleeve with little play.
  • the contact force arises from the locking of the plug connection via a housing to be constructed accordingly, which additional functions, such as. B. Centering, leadership and sealing takes over.
  • the two parts, contact pin 1 and contact socket 2 can be made of copper, brass, bronze, silver, gold or any other electrically conductive material, thereby optimizing the electrical conductivity.
  • An additional upper surface treatment, treatment or coating, which has an advantageous effect on the transition and / or the total contact resistance, can ever are currently very easy to use and / or apply.
  • Contact pin 1 and the contact socket 2 can be connected with solder, crimp, screw connection or any other connection technology to the appropriately shaped connection areas 9 a and 9 b with corresponding electrically conductive lines, in particular cables.
  • these contacts can also be used in multi-pole connectors and plug-in devices, the number of poles of which is limited only by design-related limits or the required closing force of the connector housing.
  • Both parts, contact pin 1 and contact socket 2, have an electrical function and are therefore made of conductive material.
  • the plug-in path can be precisely dimensioned using modern manufacturing processes and the axial contact force can be established and maintained by suitable constructions in the housing, which means that the contact resistance can be calculated even with many plug-in cycles.
  • the ring line contact system can be manufactured with minimal internal friction and the smallest plug-in paths, in relation to the respective cable cross-section and the contact size.
  • the contact contact force on the conical contact surface can be increased many times, depending on the pitch angle of the cone.
  • the plug-in path of the ring line contacts largely determines the closure and thus also directly the size / length of the housing with, for example, a bayonet or screw closure.
  • the ring line contact system increases the performance, operational safety and efficiency of electrical systems. It reduces energy losses in electricity generation, storage, distribution and e.g. Charging stations for e-mobility via bad or damaged plug contacts. Not to mention the resource saving when using the much more compact ring line contact system.
  • the ring line contact system is almost freely scalable.
  • connection area of the contact pin for electrical conductors (cables) 9b connection area of the contact socket for electrical conductors (cables)
