Definitions

  • the present invention pertains to a clip anchoring an eyelet terminal clamp to a terminal bar of an electric device or machine, being said clamp provided to receive and fasten external supply conductors allowing to said clip to anchor in simple and fast way the eyelet terminal to the terminal bar.
  • the clamps can be manufactured integral with the terminals themselves, what allows particularly safe clamping and connection, but implies a very high cost, only justifiable for high cost machines and devices.
  • the clamps can be manufactured separated from the terminals at a quite lower cost, but in such a case a particularly careful manufacture is needed to avoid possible poor connections and consequent overheatings.
  • One of the most common clamps is the socalled "eyelet” clamp comprised of a sleeve shaped metal member provided with threaded clamping means allowing to clamp inside said sleeve a cable to be connected thereto.
  • a partial solution for this problem is to provide an insulating basis, bearing said terminals, with bracket protrusions on which can abut said clamps when they are loosed. Said solution is only partial because can assure a gravity support of the clamps on said brackets which, for its shape is rather problematic.
  • a clip according to the present invention consists of a metallic stiff and resilient structure provided with two each oter opposite bends, of which a first one spans a terminal bar and a second one spans an eyelet clamp, and with a lifted tang engaging a bore through said bar and therefrom disengageable just on will through the use of a specific tool, as for example a screwdriver.
  • said clip is comprised of a stiff and resilient metallic strip made of materials such as bronze or beryllium copper, so punched to have a first integral area, to be put against a terminal bar, followed by at least a finger folded according to a first direction to span said terminal bar and another finger folded in opposed direction to span a side of said eyelet clamp, being the internal area abutting against the terminal bar provided with a liftable tang to be engaged in a hole through said terminal bar.
  • a stiff and resilient metallic strip made of materials such as bronze or beryllium copper, so punched to have a first integral area, to be put against a terminal bar, followed by at least a finger folded according to a first direction to span said terminal bar and another finger folded in opposed direction to span a side of said eyelet clamp, being the internal area abutting against the terminal bar provided with a liftable tang to be engaged in a hole through said terminal bar.
  • said clip on a side shows two fingers or legs spanning the terminal bar and on the other side a finger spanning a side of the eyelet clamp.
  • said clip is provided in the finger spanning a side of the clamp with a further protrusion engaging a seat in an insulating basis of the terminal to add a bearing point to said finger and make safer the anchoring operation of the clamp to the terminal.
  • an eyelet clamp engaged with said clip is comprised of a metallic strip, folded to form a first frame, having a first side comprised of two superimposed ends of said strip, crossed by a fastening screw of the clamp and a second side opposed to the first one anchored by said clip to an electric machine or device terminal, the clip retaining the clamp against the terminal and being clearable through the operation of a tang engaged in a hole of said terminal.
  • an eyelet clamp 10 is seen as comprising a rectangular window 12, obtained by folding a metal strip, which surrounds a terminal bar 14 coming out from an insulating basis 16.
  • Said window 12 has two superimposed side 18 and 20 through which pass a screw 22 whose threaded stem is engaged in a threaded hole 24 crossing the upper side 18 of the window 12, while the lower side 20 has a not threaded larger hole 26 crossed, without be engaged, by the screw 22.
  • the window 12 has a side 30, opposed to the superimposed sides 18 and 20, passing around the terminal 14 and therewith anchored by means of a clip 40 according to the present invention.
  • the clip 40 is comprised of a punched and double folded metallic strip from which protrude a downwards bent leg 44, for engaging the side 30 of the window 12, possibly ending with a restricted area 46 to be engaged in a support seat 48 into the insulating basis 16 (figures 1 and 2), and two legs 50 and 52 upwards bent, for engaging the terminal bar 14.
  • the tang 54 is provided to be possibly lowered just to clear the clip 40 from the bar 14 and allow the replacement of the clip 40 itself or the whole eyelet clamp 10, should it be damaged.
  • the operation of the present invention is the following one: when it is intended to fasten an eyelet clamp 10 to a terminal bar 14, a clip 40 is grasped and inserted around the side 30 of the clamp window 12 with the leg 44 thereof engaging said side. Then the assembly of the window 12 and clip 40, inserted around the side 30, is taken and iserted around the terminal bar 14 in such a way that the two legs 50 and 52 engage said bar 14 and the tang 54 is flattened, passing under the bar 14, meeting the hole 56 through the bar, getting rid and getting the orientation depicted in figures 2 and 3, so that said tang 54 tends to engage the walls of the hole 56 at any attempt to extract the clip 40 from the terminal bar 14, making impossible to disconnect the eyelet clamp 10 from the bar 14, unless an interrvention through a tool is made on the tang to lower it, permitting the extraction of the clip 40 from the bar 14. Once extracted from the bar 14, the clip 40 is esaslily extracted from the window 12 of the clamp 10, allowing any clamp or clip substitution in case of damages thereto.
  • the leg 44 could be upwards folded for engaging the bar 14 and the legs 50 and 52 downwards folded for engaging the side 30 of the window 12, being in this case sufficient to add a hole in the leg 44, coincident with the hole 56 of the bar 14, for allowing the insertion of a tool for the disengagment of the tang 54.
