Definitions

  • the invention relates to a contact plug for the transmission of electrical energy by detachable contact with a contact socket.
  • plug connectors For contacting or creating detachable electrically conductive connections, plug connectors, contact elements, pole connectors, sockets, etc., are used in a wide variety of designs and variants.
  • contact systems have been developed that are based on circular contact geometries for receiving a contact pin and whose starting material consists of a planar contact grid that is brought into the circular contact geometry with a hyperbolic twist.
  • These contact systems known as RADSOK, are characterized by robust and high-density contact formation due to the considerable contact area with the respective contact pin.
  • inwardly directed lamellar geometries are known, whose lamellar contact grid is radially symmetrical.
  • contact geometries preferably used as high-current contact sockets, are therefore known as radial contact sockets or hyperbolic contact sockets.
  • RADSOK contact systems of the aforementioned type are inserted into connector sockets via their generally cylindrical outer contours and achieve contact externally via the cylindrical surfaces.
  • DE 10 2007 051 266 B4 is based on the basic idea of providing a single connector socket sleeve designed to accommodate different lamellar contact cages in the form of RADSOK contact sockets, which are placed flat against the inside of the contact sleeve.
  • a comparable basic structure is shown by the DE 20 2016 100 095 U1
  • the invention relates to the coupling, connection, and contacting of the cylindrical lamellar cage "floating" within the receiving connector socket sleeve by fixing only one of the respective end flanges in the socket, for example, by press fit.
  • An electrical connector socket comprising a cylindrical socket sleeve is provided, which is designed with a receiving chamber into which a cylindrical lamellar cage with a plurality of parallel contact lamellae is inserted.
  • the lamellar cage has a first and second circumferential flange at each end, between which the contact lamellae extend.
  • the lamellar cage is fixed at one end, at least axially and preferably also rotationally fixed, in the bushing sleeve, thereby clamping or securing it.
  • an axial sliding bearing rotatable by at least a certain angle, is provided relative to the bushing sleeve.
  • the lamellar cage is fastened to the inner wall of the bushing sleeve by means of a sleeve-side fastening element via one of its flanges.
  • Such connectors and their contact elements which often consist of one or more pairs of pins and sockets, are subject to various influences, such as mechanical stress, vibrations, shocks, and aging. Significant temperature fluctuations are also possible, caused by environmental conditions or by self-heating due to the electrical current flow and the inherent resistance of the current-carrying components. Self-heating can be particularly relevant at the contact points, as the contact area is small due to contact forces, resulting in a high resistance almost entirely induced by the contact geometry. For this reason, it is of particular importance that the contact force - more precisely: the contact normal force - is as high as possible and remains constant in order to press the contact partners, usually formed by contact pin and contact socket, together at their contact surfaces for electrical contact.
  • the contact sockets available in the prior art such as the aforementioned RADSOK sockets or their plug-in contacts (plug-in pins), utilize both formative shaping processes such as stamping and rolling, and suitable materials with spring properties to generate the desired spring action through restoring forces. These forces are used to create preferably elastic contact forces between the contact partners at their contact surfaces.
  • the performance of the plug-in connection is limited by temperature effects, as higher temperatures cause a loss of spring force due to relaxation processes, material creep, and residual stress reduction. This applies particularly to copper and... Copper alloys, because copper, in addition to its generally low elasticity, becomes "soft" especially at low temperatures.
  • plug contact partners are designed in this way and made from materials such as spring steel, it is indeed possible to generate very high normal contact forces that reliably press the contact surfaces of the plug contact partners together, but assembly problems often arise because plugging the contact partners together requires high insertion forces, which make assembly difficult or require the use of tools.
  • EP 2 461 427 B1 discloses a self-deforming high-current contact based on the approach of achieving low insertion forces at room temperature for assembly and high contact force or contact normal force during operation, especially with increased self-heating and at elevated ambient temperatures, through on the one hand constructive design of the high-current contact and on the other hand providing a self-deforming element of the plug connection at rising temperature.
  • the contact normal force increases almost automatically as soon as the temperature rises.
  • the proposed high-current contact serves to transmit current from a power source to an electrical conductor of a current collector.
  • the high-current contact together with the corresponding contact pin, serves both as a mechanical connection and as an electrical contact between the current collector and the power source via an electrical contact surface between the high-current contact and the contact pin.
  • the teaching here focuses on designing the contact socket in such a way that at least the contact tip area consists of a bimetallic strip.
  • the bimetallic strip changes its shape due to the influence of heat. This change in shape is used to at least maintain or increase the normal contact force.
  • CH 613 814 A5 discloses a contact plug according to the preamble of claim 1.
  • the object of the invention is to further develop existing contacting solutions with contact normal forces that can change due to temperature influence and to at least partially reduce the existing disadvantages.
  • the invention proposes a contact plug according to claim 1.
  • the claw-like shape is formed by at least one claw-like element, approximately arc-shaped and extending partially in the circumferential direction of the plug contact pin, preferably transversely to the insertion direction of the plug contact pin into the contact socket.
  • the claw-like elements extend from a base element, which, in the insertion direction, has a continuously steady and largely linear shape with a flat surface or has a slightly curved cross-section, partially extruded so that the contact pin does not have a closed, cylindrical overall contour and the at least one claw-like element is deformable at its end.
  • the invention provides for two or more claw-shaped elements.
  • the base element in this case is practically similar to the vertebral column of the human skeletal system, in which the ribs (here: claw-shaped elements) are attached and extend transversely to the direction of vertebral extension.
  • the claw-shaped elements with their arc-like form extending circumferentially in certain areas, form sections of a cylindrical outer contour of the contact pin and have a constant or changing radius in the circumferential direction.
  • the radius decreases towards the end of the claw-like elements, so that the arc-like shape of the claw-like elements essentially curls up.
  • the deformation behavior of the claw pin which is made of multilayer metal or a shape-memory alloy, and the resulting contact normal force, which is triggered by temperature changes, can be additionally influenced geometrically.
  • the invention provides for a further, geometrically determined influence on the temperature-change-induced contact normal force through deformation of the spring-elastic, claw-shaped elements made of a multilayer metal or a shape-memory alloy by means of unequal widths.
  • the width of the claw-shaped elements i.e., their extent in the insertion direction (axial direction of the contact pin) and thus transverse to the claw-shaped, arc-like form, can increase from the first claw-shaped element arranged in the insertion direction to the subsequent claw-shaped elements located behind it in the insertion direction.
  • This results in a width-dependent difference in the deformation behavior of the claw-shaped elements because claw-shaped elements with a smaller width are subject to faster temperature changes due to their smaller overall mass under the same heat energy input. Consequently, a change in the contact normal force is achieved at different times due to the effect of the multilayer metal structure or the shape-memory alloy and the resulting deformation.
  • a protruding section of the base element can be provided as a functional element, which can be used for crimping (e.g., crimping or welding) an electrical line, cable or as a handle in the sense of a handling aid.
  • the claw-shaped elements or even the entire contact pin are made of a multilayer metal material, which, for example, is a bimetal composed of two material types. It is advantageous to form the outer region of the claw-shaped elements or the contact pin, with its contact surfaces facing the contact socket, from a copper material, and to construct the inner region, i.e., the areas of the claw-shaped elements or the contact pin facing away from the contact socket, from a steel material. Since the copper material and the steel material exhibit different thermally induced expansion behaviors, the bimetallic material deforms and causes a deformation of the claw-shaped elements, which is used to influence the contact normal force. Layered structures with three materials can also be realized, in which the middle layer consists of a copper material, thus ensuring that the multilayer metal arrangement has good electrically conductive properties.
  • the temperature-dependent deformation required to change the contact normal force is achieved by using a shape memory alloy (also called memory metals) for the contact pin or for at least its claw-shaped elements.
  • a shape memory alloy also called memory metals
  • the at least two claw-shaped elements it is possible for the at least two claw-shaped elements to be part of the contact socket instead of the contact plug. It is also possible for both the contact socket and the contact pin/plug to have claw-like elements.
  • the descriptions in the text apply analogously to these embodiments as well.
  • the invention offers a number of advantages, most notably that only low insertion forces are required when connecting the contact partners consisting of the claw pin and contact socket at room temperature, since the increase in contact normal force only occurs through the heating of the claw pin and/or the contact socket and does not need to be generated by spring-elastic preload.
  • the invention also achieves increased The contact normal force changes with temperature, specifically with increasing temperature and thus decreasing electrical resistance. As a result of this increased contact normal force, high pull-out forces (i.e., forces required to pull the connector apart) occur at operating temperature, making such connectors less susceptible to vibration.
  • Figure 1 shows a perspective view of the contact connector, which according to the invention is designed as a claw pin 20.
  • the claw pin comprises at least two constructive-geometric elements that characterize the claw pin 20: a base element 30 and at least one claw-shaped element 50.
  • the claw pin 20 can be supplemented by at least one functional element 40.
  • the base element 30 functionally forms the backbone of the claw pin 20. Viewed in the insertion direction and largely parallel to the insertion axis, it forms a continuously continuous and largely linear shape with a flat or slightly curved cross-section, from which at least one claw-shaped element 50 extends in the circumferential direction of the claw pin 20 and thus transversely to the insertion direction.
  • the at least one claw-shaped element 50 extends circumferentially around the claw pin 20 and forms a section of the cylindrical contour of the contact connector. In the section plane axial to the claw pin 20, the at least one claw-shaped element 50 has one or more different radii of curvature R, R1, R2. Preferably, two claw-shaped elements 50, located at a largely identical axial height around the claw pin 20, extend circumferentially.
  • An optional functional element 40 can supplement the claw pin assembly.
  • the functional element 40 can extend in the opposite direction to the insertion direction and be designed as an extension of the base element 30. It can have a bore, tabs, or other geometries suitable for providing additional functions, such as a grip to assist handling when connecting the contact or plug-in partners, consisting of contact socket 10 and claw pin 20, or for attaching a cable or wire (possibly with shielding) by, for example, welding or crimping.
  • Figure 2 The perspective view of the claw pin 20 is shown in a contrasting view. Figure 1 from a different viewing direction. Shown is the optional configuration of a plurality of claw-shaped elements 50, which are arranged in pairs opposite each other and mirror-symmetrically to each other at an axial height of the claw pin 20.
  • the claw width b is varied here in the qualitative manner shown such that the widths of the claw-shaped elements 50 can have two or more different values relative to each other. It is particularly advantageous to provide a width b of the first pair of claw-shaped elements 50 arranged in the insertion direction with a width b1 and a width b2 of the second pair of claw-shaped elements 50 arranged in the insertion direction, where b1 ⁇ b2.
  • the width ratio can be varied arbitrarily or kept constant over several claw-shaped elements 50.
  • a width b1 ⁇ b2 ⁇ bn of the first pair(s) of claw-shaped elements 50, which are arranged first in the insertion direction, is particularly advantageous. Due to the lower mass of these narrower claw-shaped elements 50 compared to the claw pairs located behind them in the insertion direction, these narrower claw-shaped elements 50 heat up more quickly after the contact partners and the electrical resistance are connected and an electrical voltage is applied. In this way, an initial increase in the contact normal force can be achieved early and immediately after the start of the current flow.
  • the width ratio b1/b2 of the first pairs of claw-shaped elements 50 which are arranged first in the insertion direction, relative to the claw pairs located behind them in the insertion direction, is particularly advantageous in the range of 0.3 ⁇ b1/b2 ⁇ 0.8 and preferably approximately 0.5.
  • These width ratios can be implemented in pairs or over several pairs of claw-shaped elements 50 with equal width ratios (groups of equal claw width).
  • Figure 3 illustrates the side view of the claw pin 20 from the viewing direction opposite to the insertion direction, i.e., towards the contact plug end in the direction of the contact socket 10.
  • the two claw-shaped elements 50 shown here as an example extend in a parallel and mirror-symmetrical manner and form at least partially a cylindrical contour of the claw pin 20 with an opening OE opposite the base element 30.
  • the opening OE can optionally also be used as an anti-rotation device for the claw pin 20 within the contact socket 10 when inserted.
  • a spring (not shown) can be provided in the contact socket, which engages in the opening OE and thus prevents rotation by means of a mechanical stop.
  • the claw-shaped elements 50 extend circumferentially around the claw pin 20 and have a circular arc-like shape.
  • the circular curvature of this embodiment of the claw-shaped elements 50 is not constant in the direction of extension from the base element 30; that is, the radius of curvature R decreases, at least in some areas, as the extension progresses away from the base element, such that R1 > R2. This reduction in radius can be continuous, as shown, or exhibit abrupt changes in radius.
  • the configuration R2 ⁇ R1 represents an additional, geometrically determined factor influencing the change and increase of the contact normal force due to temperature changes.
  • the deformation behavior of the claw pin 20, which consists of multilayer metal or a shape memory alloy, triggered by temperature changes, can be additionally influenced geometrically, and the locally varying deformation of the claw-shaped elements 50 can be used to adjust and increase the resulting contact normal force.
  • a radius ratio of 1.1 ⁇ R1/R2 ⁇ 3 is particularly advantageous for multilayer metals, especially bimetallic structures, as well as shape memory alloys.
  • Figure 4 Figure 1 shows a perspective view of the contact partners 1 for an electrically conductive connector, here consisting of a claw pin 20, which is inserted at least partially into a contact socket 20. Due to the temperature-induced increase in the contact normal force, the contact normal force does not need to be generated, or only needs to be generated to a reduced extent, by the elastic deformation of the contact partners before the temperature effect. This makes inserting the claw pin 20 into the contact socket 10 easier and more convenient for assembly.
  • Figure 1 shows a three-dimensional view of the contact partners 1 for an electrically conductive plug connection in the insertion direction.
  • the claw-shaped elements 50 are designed with a significant clearance relative to the contact socket at their extension end and adjacent to the opening OE at assembly temperature, which is preferably equal to the ambient temperature, thus facilitating assembly.
  • Figure 6 This shows the spatial representation of the claw pin 20, which is oriented towards the end in the insertion direction.
  • This detailed view shows the chamfer or bevel F, which is optionally and selectively implemented on one or more claw-shaped elements 50.
  • the bevel F is provided here on the insertion direction side, laterally and at the end of the claw-shaped elements 50.
