Definitions

  • the present invention pertains to an eyelet drawn clamp provided with means to be held anchored to a terminal bar of an electric machine or device even when are released fastening means of the clamp, such as screws or bolts, preventing any possible lost of a clamp left casually released.
  • the clamps can be manufactured integral with the terminals themselves, what allows particularly safe fastening 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 it needs to have particular care in their manufacture to avoid danger of poor connections and relating overheatings.
  • One of the clamps is the so-called' "eyelet” clamp comprised of a metal sleeve shaped portion provided with a threaded fasteing member, cooperating to fasten together, inside said sleeve, a terminal and a conducting cable to be connected thereto.
  • a problem connected with said eyelet clamps is their mobility with respect to the terminals, with the risk of loss, occurring when said clamps are loosed.
  • a partial solution to 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 just partial because it can assure a gravity support of the clamps on said brackets, which owing to its nature, results rather problematic.
  • An object of the present invention is just to provide a drawn eyelet clamp provided with an anchoring clip maintaing it anchored to a terminal when it is loosed, but able to clear it by means of a specifical intervention on a member engaging said clip between said clamp and said terminal.
  • an eyelet clamp comprised of a drawn sleeve insertable on a terminal bar of an electric machine or device, characterized in that said sleeve comprises a seat for receiving said bar and a clip for anchoring said sleeve to said bar consisting of a metallic resilient strip engaging at a first side a wall of said sleeve and at second one a suitable seat pierced in said bar.
  • said seat in said sleeve is comprised of an enlargement between two first lateral walls contiguous to a wall of said sleeve, communicating with a more restricted portion between two second walls defining, with said two first walls, two support shoulders of the sleeve on said bar.
  • said anchoring clip is comprised of a substantially planar strip provided with two legs, substantially perpendicular with respect to said planar strip, and a tang inclined with respect to said planar strip and coming out therefrom.
  • said two perpendicular legs of said clip engage two sides of the clamp wall and said inclined tang engages a seat pierced in said bar.
  • said seat engaged by said tang consits of a through hole across said bar is provided with a protrusion to limit the inside axial sliding of said sleeve.
  • a drawn eyelet clamp 10 consists of a sleeve 12, obtained for example by drawing, in the shape of a substantially rectangular frame, comprising a bottom wall 14, two enlarged lateral walls 16 and 18, forming two support shoulders 17 and 19 with two more restricted lateral walls 20 and 22, and a top wall 24 closing the frame of the sleeve 12.
  • Said top 24 is provided with a threaded through hole 26 wherein a screw 28, provided with head 30 and trheaded stem 32, is inserted, ending said scerw 28 with a coupling area 34 for a clamp fastening member 36, of known kind, having the task to fasten a possible conducting cable against a planar bar 38 of a terminal 40 of an electric device or machine (not shown), containing said terminal 40 a folded bar 42 provided with fastening holes 44 and 46 and a protrusion 48 on the bottom face thereof to impose axial sliding restrictions to the sleeve 12, as hereinafter explained.
  • a resilient clip 60 forming part of the present invention, and the already mentioned protrusion 48 on the bottom face of the bar 38.
  • the resilient clip 60 consists of a subsantially planar strip 62, provided with an internal U shaped opening, defining a tang 66 inclined to be upward lifted, and two descending legs 68 and 70 engaging sides 72 and 74 of the lower wall 14 of the drawn sleeve 12, while said tang 66, bieng lifted, engages a hole 76 through the bar 38.
  • the operation of the invention is the following one: while the clamp 10 is grasping the bar 38, through the thrust provided on the cable by the fastening member 36, it cannot absolutely happen that the clamp runs out from the bar 38 because the bottom wall 14 of the sleeve 12 is fastened against the bar 38 itself.
  • the fastening of the member 36 on the cable is loosed, not only the cable is extractable out from the sleeve 12, but the sleeve itself is no more stricly fastened against the bar 38, so that other means have to operate to prevent the loss thereof from the bar 38.
  • the provisions of the present invention are intended the provisions of the present invention.
  • the internal shoulder 17 and 19 of the sleeve 12 descend to rest on the bar 38, preventing the detachment of the sleeve itself for descent, while an axial sliding thereof on the bar 38 is prevented by the protrusion 48 and by the resilient clip 60 in the herebelow depicted way.
  • the back protrusion 48 prevents an axial backsliding of the sleeve 12, while the resilient clip 60, engaging with the descending legs 68 and 70, respectively the respective fore and back sides 72 and 74 of the bottom wall 14, prevents any substantial axial foresliding because of the engagement of the inclined tang 66 with the adjacent wall of the cylindrical hole 76.
  • a sleeve 12 For assembling a clamp according to the present invention, it is sufficient to take a sleeve 12, with the respective fittings, such as the screw 28 and the fastening member 36, to provide it with a clip 60 and insert them into the bar 38, making to enter the same through the side 72 of the bottom wall 14 and the descending leg 68 of the clip 60 into the same sleeve 12 until the latter stops against the lower protrusion 48.
