Definitions

  • the present invention relates to an electrical appliance plug pin for a plug bridge of an electrical wall plug, having annular grooves designed so as to improve plug strength and reduce manufacturing costs at the same time.
  • the bridge plate of the plug bridge as proposed by the present invention, is perpendicular to the axis of the pin in the region of the annular groove and is provided with an improved retention force due to the improved design provided to electrical plug pin in that region.
  • annular grooves are inadvantageous in the sense that they are yet subject to improvements, taking necessary manhour needed for equipping electrical plug pins with annular grooves and knurlings into consideration is also of great relevancy and any improvement to render manufacturing process faster and electrical contact pins more reliable is still welcome in the electrical components industry.
  • German patent DE 3840140 C2 discloses an electrical plug pin with annular grooves secured within thickness of moulded plastic bridging piece by milled edges or bed of groove.
  • German patent DE 19627335 C1 discloses an electrical plug pin having annular grooves machined in conventional position under head of pin but divided axially into three portions of unequal length. The division of the groove into three rings in succession along the axis, each with its own milled edge, is intended to increase the security of retention of the pin in the axial direction.
  • the milling operation as a step of the machining process, is carried out in a plane lying at right angles to the axis of the plug pin, which results in the formation of relatively lower grooves along the rings due to ongoing concerns in relation to material stability.
  • the depth of the grooves in the milled portions of the plug pins will be limited to the material characteristics of the alloy and will hence be exposed to stability concerns.
  • the present invention provides a more improved plug pin equipped with a series of deeper grooves along the ring due to the unique shape given through milling operation so as to enhance material stability and at the same time to ease and speed up manufacturing process.
  • Greatest advantage of the present disclosure over prior art thereby lies in the fact that the security of retention of the pins provided hereby is improved to the extent that the pin is free of immobilisation loss both in radial directions and in axial direction.
  • One of the objects of the present invention is to modify the shape of the annular groove section in an electrical plug pin in order to increase the security of retention of the same in both axial and radial directions.
  • Another object of the present invention is to provide a more improved plug pin equipped with a series of deeper grooves along the ring due to the special shape given through milling operation at its groove section so as to enhance material stability and to ease and speed up manufacturing process.
  • Yet another object of the present invention is to provide deeper grooves, which are not extending along the lateral surface of the pins but along an inclined annular surface formed in between the outermost and the innermost diameters of the pins so as to increase immobilisation against rotation.
  • Still a further object of the present invention is to provide a depth vector being greater than the vertical component of the same, though the latter being not greater than those in the prior art that are applied through perpendicular milling, and thus providing the system with deeper grooves without forcing material strength limits.
  • an object of the present invention is to increase rotational force of workpiece pins by increasing the magnitude of the force exerted on the same during milling operation due to formation of two distinct contact directions on which two distinct force vectors are induced, which is ensured by indined positioning provided between the cutters and the lateral surface of the pins.
  • an object of the present invention is to increase revolutions per minute (and hence output per unit time) of the workpiece pins secured to a carriage of the milling tool, by increasing rotational force of the same due to exertion of a force at a greater magnitude by movable parts of the milling machine.
  • an object of the present invention is to increase operation life of the cutters of the milling tool due to inclined working plane producing two distinct contact directions on which two distinct force vectors are induced and a greater force hence exerted on the pins during milling operation.
  • an object of the present invention is to decrease production losses due to improved material strength provided by deeper grooves, which are cut in an inclined manner.
  • the objects described above are achieved through use of a conventional pin having a cylindrical shank and a short cylindrical portion for connection to a cable termination, with the two cylindrical portions separated by an annular groove milled throughout its length.
  • the milling operation is carried out in an indined manner, that is the milling tool is provided with a contour which lies in a projection plane that is inclined with respect to the axis of rotation of the milling machine by arranging the spindle unit of the milling tool to spatially modify the orientation of the axis of rotation of the milling tool.
  • This milling operation as a step of the machining process, is improved so as to provide two opposite surfaces perpendicular to which are extending two contact directions on which two distinct force vectors are induced insofar as no loss of immobilisation against rotation incurs.
  • the link plate (8) of the plug link being a plastic part which is injected or extruded around the plug pin (1) or plug pins in the region of the annular groove (9), in a plane lying generally at right angles to the axis of the plug pin (1).
  • a conventional pin (1) has a cylindrical shank (2) and a short cylindrical portion (6) for connection to a cable termination (7), with the cylindrical portions (short cylindrical portion, 6 and the pin, 1) separated by an annular groove (9) milled throughout its length so as to comprise a throat (4) under and above which the rings (3, 5) are located in the manner disclosed hereafter.
  • the invention comprises a division of the groove portion (9) into a plurality of rings (3, 5) in succession along the axis, each with its own milled edge with the edge parts being treated on a milling machine in an inclined manner. This modification increases the security of retention of the pin (1) both in radial directions and in the axial direction.
  • the milling operation is carried out in an inclined manner, that is the milling tool is provided with a contour which lies in a projection plane that is inclined with respect to the axis of rotation of the milling machine by arranging the spindle unit of the milling tool to spatially modify the orientation of the axis of rotation of the milling tool.
  • electrical plug pins (1) which are secured to a carriage of a milling machine, are treated in the manner that the movable parts of the milling machine cut the terminal pins (1) to provide them with inclined edge grooves (10) along the rings (3, 5) instead of rectangular edge ones having right angled edges.
  • the grooves (10) along the rings (3, 5) are not designed so as to extend parallel to the longitudinal axis of the pin (1) and lye on the lateral surface of the same, but to lye on an annular surface (13) inclined in between the outermost and the innermost diameters of the pin (1).
  • the protruding portions of the grooves (10) along the rings (3, 5) do not protrude radially and the axis on which said protruding portions extend is not juxtaposed to the longitudinal axis of the pin (1).
  • grooves (10) in the form described above is achieved through position adjustment of the cutters in a plane that is not perpendicular to the longitudinal axis of the pin (1).
  • the workpiece pins are treated in a bilateral way so as to form grooves with every single groove (10) along the rings (3, 5) having both of its opposite surfaces (Fig. 4a, 11) given indination at once, thus resulting in the formation of two distinct contact directions juxtaposed to the surface (11) normals of the grooves (10), on which two distinct force vectors are induced.
  • the latter also increases operation life of the cutters of the milling tool due to an improved material strength allowing exertion of a greater force magnitude on the pins (1), provided by the inclined working plane producing two distinct contact directions. Furthermore, the improved material strength has also the positive effect to eliminate production losses along milling operation.
  • Another aspect to enhance the security of retention of the pins (1) in the plug plate (8) according to the present invention lies in the fact that the outermost parts (12) of the protruding edges of the grooves (10) goes slightly beyond the outermost diameter of the pin (1) so as to form an additional physical barrier impeding free movement of the pins (1) in both axial and radial directions.
