Definitions

  • the invention relates to a method for producing a contact pin for use on lighting means, wherein initially a metal strip is formed into a tube and this is cut to the contact pin below.
  • a common method is to produce the contact pin contour from a rod material. This can be done first by a forming process and / or by machining. By this method, a great freedom of design for the shape of the contact pin is achieved. Among other things, the required tolerance in terms of the outer diameter can thus be achieved in a simple manner.
  • a plurality of contact pins is usually produced at the same time. For this purpose, remains during punching a plurality of developments via webs connected to a transport grid. Thus, the transfer from a tool nest into the following tool nest also takes place simultaneously for a plurality of contact pins. This measure is also required to ensure the necessary precision when inserting into the tool nest.
  • This transport lattice can comprise both a plurality of developments as well as a plurality of deformation stages in the process sequence.
  • a method according to the invention is proposed for the production of contact pins for use on illuminants, with which the task of eliminating the waste is solved.
  • An essential feature is the process sequence with a first forming process in which a continuous sheet metal strip is formed by profile rolling in several stages to form a substantially closed tube. This substantially endless tube is cut to length in a subsequent process step and thus forms the contact pin according to the invention.
  • a contact pin is produced for use with lighting means, wherein the contact pin forms, at least in sections, a hollow cylinder.
  • the hollow cylinder is required in order to be able to guide and contact a contact element, usually a wire, of the luminaire.
  • An inventive feature of the contact pin is that this hollow cylinder is formed from a section of a profile-rolled sheet-metal strip. The result of the production process is that the edges of the metal strip form a gap on the hollow cylinder, the gap consequently being parallel to the longitudinal axis of the contact pin.
  • the contact pin will be hollow throughout and is surrounded only by the lateral surface.
  • the contact pin As intended use of the contact pin, only illumination means are initially provided from the existing field of application. However, it is equally conceivable to use such a contact pin for other purposes. This is especially true for use in the functional task as on one side often without damage easily mounted plug contact for the preparation of an electrical connection, the second side is intended to be firmly connected to an electrical device or means. Thus, it is obvious that the term lighting means is not limited to lighting, but in terms of the purpose of the contact pin.
  • the deformation in the first step is initially carried out by two, in particular more than two, first pairs of rollers.
  • first pairs of rollers are the axes of the first pairs of rollers perpendicular to the plane of symmetry of the metal strip in the transformation.
  • the plane of symmetry is in a perpendicular manner perpendicular to the metal strip and passes through the center of the metal strip or the tube formed below.
  • the edges of the sheet metal strip are first bent and form a first portion on both sides of the gap of the later resulting tube. Subsequently, the forming is continued until the middle of the metal strip.
  • second pair of rollers is required to form the largely closed tube.
  • the axes of the second roller pair are advantageously perpendicular to the sheet metal strip plane.
  • the sheet metal strip plane is the plane that runs through the undeformed metal strip.
  • roller pairs are in each case aligned parallel or perpendicular to the sheet-metal strip plane.
  • the first process step is extended in a particular embodiment in the following to additionally provide contour smoothing after the forming.
  • the largely closed tube is guided with groove from the previous forming process through a first receptacle.
  • the diameter of the tube is reduced and the existing groove is reduced in width.
  • the receptacle has a diameter in the exit of the receptacle, which is less than that
  • Diameter of the supplied tube before recording For supporting and centering, a cylinder comes to rest inside the tube. This is not exactly to be understood as a cylinder, inasmuch as there is a slight conicity, which is reduced from the tube inner diameter before this process step to the tube inner diameter after the process step.
  • the connection of the cylinder is advantageously carried out before recording, wherein the cylinder is connected via a connection through the groove in the tube fixed to the first receptacle.
  • this tube with a reduced groove width is guided in the following in a further process step through a second receptacle.
  • a tensile force is applied after the second shot to the finished calibrated tube.
  • an exact outer diameter is achieved with the required tolerances. If the groove width has not previously been reduced to the minimum in the process step, the groove width is reduced to the gap at the latest during this calibration process, during which the two edges of the sheet metal strip substantially touch each other.
  • the first receptacle and the second receptacle structurally form a unit.
  • the contact pin forms a first end, a contact portion, the intended plug-in contact and is designed to be assembled and disassembled many times.
  • a second end, a mounting portion on the other side of the contact pin, is provided to be fixedly connected to the electrical component.
  • the first end is slotted by means of a saw cut.
  • at least two or more slots are introduced into the end of the contact pin at the first end.
  • the first end of the contact pin has a tapered end in the manner of an insertion bevel to allow safe easy use of the contact pin.
  • a taper is advantageously formed at the first end by means of a further process step. This is done in a simple design by a compression process.
  • the taper is provided to connect the conductor or the cable by soldering or welding to the contact pin in the region of the taper. If the first end of the hollow cylinder is first slotted at the first end, this facilitates the diameter reduction.
  • the assembly in this lighting means is simplified in that a covenant in approximately the middle of the contact pin, or, depending on the embodiment in deviating position, is present.
  • This collar forms a stop, which defines the exact axial position in the manufacture of the lighting means on the one hand when inserting the contact pin in the intended opening in the lighting means.
  • the federal government forms the fixation of the contact pin in the lighting means when it is fastened by means of rivets therein.
  • This collar is created by a compression process of the contact pin. As a result, the length of the istsägten pipe section is reduced, and the sleeve expands locally forming the radially projecting collar.
  • the compression processes to form the taper and to form the collar can also be done simultaneously.
  • the sleeve of the contact pin is bent in the housing behind the wall to the outside. Therefore, it is advantageous if the Nietansatz consists of several segments instead of a hollow cylinder. Accordingly, slits are advantageously introduced into the sleeve at the second end. This can be done in a simple manner by a saw cut, which generates parallel to the axis with a cut two slots. A slot is already formed by the gap being present in the sleeve.
  • the second end is formed into a cone.
  • the cone is not as accurate in a natural way To understand rotary envelope surface, since this is formed by the bending of the segments in the radial direction inwards.
  • the contact pin can be deburred by a subsequent final method step.
  • a straight sheet metal strip is required. Of less importance is the length of the metal strip, with a greater length being more advantageous than a shorter length, in so far as fewer process interruptions are the result.
  • the metal strip may optionally be designed as a flat sheet material, but is advantageously supplied wound up on a coil. In this respect, it is necessary in a step before the actual deformation of the tube to unwind the metal strip from the coil and straighten it by a system so that it can be fed to the process step according to the invention.
  • Fig. 1 shows the first process with the deformation of the sheet metal strip to the pipe with gap
  • Fig. 2 shows a possible embodiment with further follow-up processes for forming an embodiment of the contact pin.
  • FIG. 3 shows various embodiments of a contact pin according to the invention
