Definitions

  • Present invention refers to a connecting socket which can be either mounted to the end of a conducting rod, or be a double insertion socket, being said socket provided to fasten a conducting blade of a bus-bar coming out either from an electric machine or an electric insertable device or eqiupment.
  • Connecting sockets used to connect two electric conductors, are well known since long time, being one of the conductors usually fixed and the other movable, and being for example one comprised within a control board and the other associated to devices insertable with respect to said board.
  • a connecting socket comprise at least a block or central body, substantially planar, of parallelepidal shape, in good electrically conducting material, having on opposed sides laminar resilient fingers, also electrically conducting, giving the socket a substantial appearance of a two legs fork, useful to press, for providing connection, a strip shaped conductor or blade connected, for example, to insertable devices, being said socket either of simple kind fastened to a bus-bar, operating also as a central body, or of double kind comprising a central body from which protrude in two opposed directions two laminar finger assemblies to alllow connection between conducting blades of different devices, or between the bus-bar of a control board and the blade of a device.
  • said repelling forces are proportional to the square of the current producing them and that currents flowing in parallel conductors, even if they are each other proximate, are substantially ininfluent on said repelling forces, so that if, for example it is possible to halve the current flowing between a conductor and a finger leg by just dividing said finger in two legs, said repelling forces are reduced to about a quarter while the resilient forces due to the fingers are just halved, resulting in a higher capacity of the socket to resist to ovecurrents.
  • this principle is exetensible in the sense that said finger can be divided in more than two parallel legs (for example three) with apparent higher advantages in term of lesser repelling forces and better resilient forces to resist thereto.
  • Another fact from which arises the present invention is the fact that the materials assuring the highest electric conduttivity usually do not have so good mechanical features to allow a good reaction against the above mentioned repelling forces, while the materials having sufficient mechanical features usually have poor electric conduttivity so that it is necessary to separate the current carrying members from the members providing the repelling forces.
  • the external resilient strips resting against the internal strips are similarly shared. Further, the external resilient strips are planar obtainable from a web without any subsequent thermal treatment and, as a consequence, are of the highest manufacturing simplicity and highest operating reliability.
  • said legs sharing the internal and external strips are two in number.
  • said legs are three in number.
  • said legs are in a number hihger than three.
  • said external strips are directly resting against said internal strips.
  • said external strips are resting against said internal strips through an intermediate insulating layer which electrically insulates the internal conductive strips from the resilient external strips.
  • just the conductive internal strips are divided in a plurality of paralllel legs, while the external strips are in one piece and resting against the internal strips through an insulating layer.
  • a simple connecting socket 10 is comprised of two lateral flanges 12a and 12b surrounding a central body 14 having shape of a flat parallelepiped of metallic electrically well conducting material, which in this specifical case is the prosecution of a bus-bar largely used in electric plants and in electric power distribution and control boards.
  • the two lateral flanges 12a and 12b comprise two internal well conducting strips 16a and 16b, for example made of copper, externally terminated by expanded inserting and contacting areas 18a and 18b suited for assuring insertion in the socket 10 and a good electric contact with an external conductor to be inserted in said socket, two possible intermediate strips 20a and 20b of electrically insulating material and two resilient external strips 22a and 22b having the task to provide a prevailing thrusting force against the internal conducting strips 16a and 16b.
  • any internal conducting strip 16a and 16b is shared in three parallell legs 16a1, 16a2 and 16a3 (shown in figures 1 and 3) and 16b1, 16b2 and 16b3 (not shown) among which is substantially equally shared the current, ending with inserting and contacting areas, also shared, 18a1, 18a2 and 18a3, against which are obviously opposed iserting and contact areas 18b1, 18b2 and 18b3 (not shown), said strip sharing having a herebelow explained purpose.
  • strips 20a and 20b , 22a and 22b are similarly shared, as shown by the legs 22a1, 22a2 and 22a3 depicted in figures 1 and 3, and are used to provide resilient thrust to the underlying legs 16a1, 16a2 and 16a3 of the conducting strip 16a.
  • a conducting blade 30 is inserted between the flanges 12a and 12b of the socket 10 by thrusting aside the two strip assamblies 16a, 20a, 22a on a side and 16b, 20b and 22b on the other and assuring a contac with the areas 18a and 18b, where the legs 22a1 ,22a2, 22a3 and 22b1, 22b2 22b3 of the strips 22a and 22b provide fastening thrust to the conducting strips 16a and 16b against the sides of the conducting blade 30.
  • a double insertion socket 40 is seen as comprising two pairs of lateral flanges 42a, 42b and 44a, 44b fastened around a central socket body 46 and made by two internal strips 48a, 48b and 50a, 50b of highly conductive material, as for example copper, surmounted by inserting and contacting areas 52a, 52b and 54a, 54b, respectively and possibly surrounded by two insulating external strips 56a, 56b and 58a, 58b having the task of electrically separate internal copper strips 48a, 48b and 50a, 52b from external resilient thrusting strips 60a, 60b and 62a, 62b, respectively, having the task to thrust against the copper strips 48a, 48b and 50a, 50b.
  • highly conductive material as for example copper
  • anyone of the internal strips 48a, 48b and 50a, 50b is shared in trhee legs 48a1, 48a2 48a3 and 50a1, 50a2, 50a3 (depicted in figures 5 and 7) and 48b1, 48b2, 48b3 and 50b1, 50b2, 50b3 (not shown), bearing anyone a substanially equal current share, for the herebelow disclosed purposes.
  • the inserting and contacting areas 52a, 52b and 54a, 54b are also shared in subareas 52a1, 52a2, 52a3 and 54a1, 54a2, 54a3 (depicted in figures 5 and 7) and in subareas 52b1, 52b2, 52b3 and 54b1, 54b2, 54b3 (not shown).
  • the external resilient thrusting strips 60a, 60b and 62a, 62b are also shared in three legs 60a1, 60a2, 60a3 and 62a1, 62a2, 62a3 (depicted in figures 5 and 7) and 60b1, 60b2, 60b3 and 62b1, 62b2, 62b3 (not shown), correspondingly sharing the forces on the underlying conductive strips 60a, 60b and 62a, 62b.
  • conducting blades 70 and 72 between the flanges 60a, 60b and 62a, 62b is particularly depicted in the figures 7 and 8, where said conducting blades are shown coming into said flanges, phusing aside them and providing a good contact therewith through the inserting and contacting areas 52a, 52b and 54a, 54b.
  • the contact between the blade and the socket happens substantially around the inserting and contacting expansions 18a and 18b, so that in case of overcurrents repelling forces between said blade and expansions are developped at the passage points therebetween.
  • the flanges 12a and 12b of the socket 10 are anyone shared in three longitudinal parallel legs, being particularly the internal contact strips 16a and 16b shared in parallel legs 16a1, 16a2, 16a3 and 16b1, 16b2, 16b3 (not shown) surmounted by inserting and contacting expansions 18a1, 18a2, 18a3 and 18b1, 18b2, 18b3, of which only the expansions 18a1, 18a2, 18a3, are visible, abutting every leg of the internal strip 16a against a corresponding external leg 22a1, 22a2, 22a3 of external strip 22a and, abutting obviously every leg of internal strip 16b against a corresponging external leg 22b1, 22b2, 22b3 (not shown ) of external strip 22b.
  • the parallel legs 16a1, 16a2, 16a3 and 16b1,16b2, 16b3 of the strips 16a and 16b obviously share the currents flowing between conductive blade and socket developping at the expansions 18a1, 18a2, 18a3 and 18b1, 18b2, 18b3 repelling forces whose magfnitude is substantially a ninth (a squared thrid) of the forces developped if the internal conducting strips were not longitudinally shared, while the resilient forces due to the legs 22a1, 22a2, 22a3 and 22b1, 22b2, 22b3 of the external strips 22a and 22b reduce to just a third with apparent more favourable ratio between the repelling forces and the reactive forces due to the legs of the external strips.
