Definitions

  • the invention relates to a direct conductor contacting device for electrically connecting a first stranded wire and a second stranded wire, each of which is stripped at one end, as well as an electrical device and the use of a direct conductor contacting device.
  • soldered connections Fixed connection by means of soldering is also known from the prior art.
  • the contact properties deteriorate over time due to oxidation of the tin. This increases the volume resistance of this electrical connection, which means that it can assume increased temperatures.
  • solders are usually expensive materials.
  • electrical direct contacting is known from the prior art, in which, for example, two parallel or anti-parallel oriented strands are pressed against one another by means of a pressing force, so that an electrically conductive connection is established.
  • a directed contact pressure In order to orient the strands and to apply a directed contact pressure, however, devices made of numerous components are often necessary, which require a great deal of constructive effort.
  • the object of the invention is to improve the state of the art.
  • a conductor direct contacting device for electrically connecting a first stranded wire with a second stranded wire, the first stranded wire and the second stranded wire being stripped at one end, with a first opening and / or a second opening and / or further openings which has or each have an opening edge, and a clamping spring, wherein the opening or openings is or are designed to receive the stripped end of the first strand and to receive the stripped end of the second strand and is or are arranged such that the stripped end of the first strand and the stripped end of the second strand in the opening or in the respective openings can be introduced parallel or antiparallel and mechanically contacting and the clamping spring is arranged and designed such that a clamping force of the Clamping spring presses the stripped end of the first strand against the stripped end of the second strand, so that an electrically conductive connection of the first strand with the second strand can be realized and the electrical contact is designed to be mechanically firmly detachable
  • a core of the invention is therefore in particular that two strands are inserted into an opening or two opposing openings and thus oriented and are pressed against one another by means of the clamping force of the clamping spring, whereby an electrically conductive connection is realized.
  • the spring force also compensates for the flow of the contacted materials, so that the electrical connection is guaranteed in the long term.
  • An “electrical connection”, also called “electrical contacting”, is understood to mean, in particular, the establishment of electrical conductivity between two components. These components can in particular be part of an electrical circuit. In particular, strands are used as components.
  • a “stranded wire” is in particular an electrical conductor made up of several wires which are bundled or wound to form a larger conductor. As a result, a stranded wire is more flexible than a solid metal wire of the same cross-sectional area. However, a stranded wire can also be understood to be a “flexible” solid wire which is flexible enough to be connected in an electrically conductive manner to another wire by means of a clamping force.
  • An “opening” can be understood to mean a recess in a component.
  • the stripped end of a strand or the stripped ends of the strands are passed through the opening.
  • opening edge is understood in particular to mean an edge which is formed by the opening.
  • the surface of the opening edge can be transverse to the surface that surrounds the opening.
  • a “clamping spring” can be a component which provides a clamping effect by means of spring pressure. This can in particular be a spiral spring. The stripped ends of the first strand and the second strand can thus be pressed against one another by means of the clamping spring.
  • a “clamping force” is in particular a force which acts on a surface of a component and thus fixes the component in a certain position, since moving the component is made more difficult by "high friction” due to a spring pressure of the clamping spring on the surface.
  • the clamping force is conveyed via the opening edge and the spring effect.
  • a "stripped end of a stranded wire” can be a part of a stranded wire that does not have an insulating plastic sheath and therefore enables a current to flow when it comes into contact with an electrically conductive component.
  • the stripped end of the strand can be located either at one end or at a central part of the strand.
  • parallel Two components are in particular “parallel” or “antiparallel” if they run or are arranged next to one another at essentially the same distance.
  • parallel can be understood to mean that both stripped ends of the strands point in the same direction, whereas in the case of an "anti-parallel” arrangement the stripped ends of the strands point in the opposite direction.
  • a “mechanically firmly releasable electrical contact” is understood to mean an electrical connection which does not release automatically under normal load, but can be released manually or with the aid of a tool.
  • the conductor direct contacting device is designed as a flat element and at the same time as a clamping spring with two openings and has a longitudinal axis, a transverse axis, an upper side and a lower side, the flat element being reversibly bendable about the transverse axis and the openings thus along the longitudinal axis are arranged that in a bending position the strands can be guided through the openings so that the strands are guided through the openings partly along the top and partly along the bottom, and in a clamping position the clamping force can be transmitted to the strands by means of the opening edges.
  • the first strand can be electrically conductively connected to the second strand.
  • the flat element is first moved from a rest position by means of bending into a bending position, so that the flat element is under mechanical tension.
  • the openings are arranged in the planar element in such a way that they are in particular in a bending position on an axis so that the strands can be inserted into the openings.
  • the flat element relaxes Part of the element, moves into a clamping position and exerts a clamping force (spring force) on the strands.
  • the conductor direct contacting device can thus consist of a single component which has only two openings. A structurally simple structure is thus possible. Furthermore, only a few process steps are necessary to manufacture the direct conductor contacting device.
  • the conductor direct contacting device can be made entirely or partially from an electrically conductive material. In this case, electrical conduction is also made possible by means of the direct conductor contacting device which connects the strands.
  • the conductor direct contacting device can thus reduce the electrical resistance and even serve as an alternative power line with only two contact resistances if the direct power line between the strands is interrupted.
  • a “flat element” is understood to mean, in particular, a plate-shaped component.
  • the flat element is usually longer than it is thick or wide.
  • the flat element can have a (pre) curved shape.
  • “Bendable” can be understood to mean that a component can be deformed by an operator using physical strength, directly by hand or indirectly by means of a hand-operated tool.
  • the openings are round, oval or angular.
  • Angular is understood to mean in particular a shape which is not round.
  • a round, oval or angular shape of the openings can improve the hold of the strands in the openings. This is achieved in particular in that the shape of the opening is adapted to the shape of the strands.
  • a further embodiment has a guide element, a first panel element and a second panel element, the first panel element and the second panel element each having a clamping spring receptacle and one of the openings, and the first panel element and the second panel element being arranged planar to one another, the guide element being the first panel element and the second panel element is assigned in such a way that the first panel element and the second panel element are mutually planar displaceable on a thrust axis, so that the panel elements can be transferred from an insertion position to a clamping position, wherein the clamping spring is arranged between the clamping spring receptacles that the The clamping spring can be reversibly tensioned in the direction of the thrust axis, the clamping spring is tensioned in an insertion position, the first opening and the second opening are arranged overlapping in the insertion position on the first panel element and the second panel element, and the like nd form an overall opening, so that the first strand and the second strand can be inserted into the openings, the clamping
  • the first panel element and the second panel element are in particular displaceable relative to one another on only one axis.
  • the "clamping position" and the “insertion position” can represent end positions and further displacement can be prevented by limiting elements. Since the openings are each made in the panel elements, the openings can also be displaced relative to one another, in particular on only one axis.
  • the displacement of the panel elements relative to one another is limited in particular to one axis by means of the "guide element".
  • the openings overlap, they can form an overall opening so that the strands can be pushed through both panel elements with a sufficiently large overall opening.
  • the total opening In the insertion position, the total opening can be larger than in the clamping position.
  • the clamping force caused by the spring tension tends to reduce the overall opening so that when the strands are inserted, the clamping force results in a clamping connection between the two strands.
  • the total opening results from the overlapping area of the openings on a push-through axis.
  • the conductor direct contacting device can also be used in spatially confined spaces, since the thickness of the conductor direct contacting device can be limited to the thickness of two panel elements, thus enabling a low overall height. Furthermore, a thickness of the direct conductor contacting device is not increased in particular during the clamping process.
  • the conductor direct contact-making device can do without the use of bent components, so that manufacturing outlay is reduced.
  • the clamping spring is a compression spring or a tension spring and is designed, for example, as a spiral spring.
  • a "clamping spring receptacle” can be a device which securely attaches a clamping spring on one side. A spring is clamped in particular by using two clamping spring receptacles.
  • the "guide element” can limit the planar displacement of the panel elements relative to one another on one axis.
  • a guide element is, for example, a hook that is attached to one panel element and engages around the other panel element, or it is a housing, which surrounds both panel elements and thus restricts a direction of movement.
  • the opening or openings are designed in the shape of a drop, or the opening or openings has or have a conically tapering shape.
  • Drop-shaped is understood to mean a shape in which one side of the opening is tapered and the opposite side of the opening is round.
  • the shape of the opening or openings allows the braid to be bundled. In this way, prior twisting of the braid can be omitted and a work step can be saved.
  • the openings in the panel elements are twisted against each other. This enables bundling to take place from two spatial directions. A bundling of the braid is thus realized in a reinforced manner.
  • the first panel element has the guide element.
  • the panel element and the guide element can be manufactured in one piece, so that less manufacturing effort is required.
  • the object is achieved by an electrical device which has a conductor direct contacting device as described above having. This realizes the above advantages.
  • the object is achieved by an above-described conductor direct contacting device for electrically connecting a stranded wire to a second stranded wire, which is stripped at one end.
  • a direct contact-making device 101 is formed by a clamping plate 117 with a first oval opening 103 and a second oval opening 105. An edge of the first opening 103 and an edge of the second opening 105 each form an opening edge 115.

  • the first opening 103 and the second opening 105 are each oval and 1.2 cm long (along the longitudinal axis 150) and 0.4 cm wide (parallel to a transverse axis 148).
  • the first opening and the second opening are 1.8 cm apart when not bent.
  • the clamping plate 117 is pre-bent by approx. 35 ° about the transverse axis 148.
  • a bending angle 133 is determined by the surface of the top of the clamping plate 127 of the left end 129 and the Surface of the top 127 of the right end 131 is defined.
  • the opening edges 115 run 90 ° to the top of the clamping plate 127.

  • the stripped end of the second strand 113 is first pushed into the second opening 105 and then through the first opening 103. Then the stripped end of the first strand 111 is pushed first through the first opening 103 and then through the second opening 105, so that the stripped end of the second strand 113 and the stripped end of the first strand 111 are aligned antiparallel to one another.
  • the pliers are then opened so that the clamping plate 117 relaxes and springs back in the direction of the starting position.
  • the clamping plate 117 thereby transmits a clamping force to the stripped end of the first strand 111 and the stripped end of the second strand 113 by means of the opening edges 115, so that they are pressed together and contacted in an electrically conductive manner.
  • a direct contacting device 201 has a first sheet metal sheet 219 with a first teardrop-shaped opening 203 and a spring recess 246, a second sheet metal sheet 221 with a second teardrop-shaped opening 205 and a spring recess, a compression spring 233 and four lateral gripping hooks 235.

  • the spring recess 246 in the second sheet metal sheet 221 is smaller than the spring recess 246 in the first sheet metal sheet 219, so that the compression spring 233 comes into contact at one end only with the second sheet metal sheet 221.
