Definitions

  • the invention relates to a U-shaped sectional bus bar for use in heavy current applications with terminal lugs for spade connectors, the bus bar comprising a web and side flanges.
  • Bus bars normally consist of sectional copper or aluminium bars onto which terminal lugs have been fixed for use with connectors. In many instances such bus bars have to resist forces of both a mechanical and an electrical nature, e.g. in the case of unintentional short circuits.
  • the said terminal lugs can be punched or stamped in the bus bar proper. If the bus bar consists of sheet metal which by itself has only little rigidity, then it may be still further weakened by the punching of terminal lugs. If, on the other hand, the bar bar is sectional, by punching the terminal lugs in the bus bar in a suitable manner any appreciable weakening may be avoided.
  • An object of the invention is to provide a construction which combines the advantages of known constructions in such a way that the bus bars acquire sufficient rigidity, at the same time as saving material by reducing the gauge of material required. Furthermore, special clamping provisions for branching may be avoided, thereby reducing the manual work needed when making installations inside cabinets.
  • the bus bars may be manufactured from copper or aluminium strip by simple punching and folding steps.
  • bus bar which is only slightly reduced in strength as compared with a similar bus bar without punched terminal lugs.
  • the connectors are disposed in the space between the side flanges.
  • the bus bar according to the invention may be characterized in that the free ends of the side flanges in the U-shaped section may be bent so as to obtain a still more rigid construction.
  • Fig. 1 shows the web 1 in which a hole 2 is drilled or punched for mounting the bus bar onto a frame or similar, and two terminal lugs 3a and 3b. These terminal lugs 3a and 3b are bent inwards into the space between the side flanges 4a and 4b at an angle of approx. 45° with respect to the web 1, which may be seen most clearly in Fig. 2. As is common in terminal lugs for space connectors, the lugs 3a and 3b are provided with small holes 5a and 5b. In Fig. 3 it can be seen that the ends 6a and 6b of the side flanges 4a and 4b are bent inwards at right angles.
  • bus bars An example of three bus bars according to the invention disposed in parallel is shown in Fig. 4.
  • the bus bars are fixed to a frame 7 by means of screws 8.
  • the various parts of the bus bars are numbered in the same manner as above.
  • the cross section of the bus bar shown in Fig. 5 differs from the cross sections shown in Figs. 1-4 in that there are no bent-in flange ends.
  • the ends 6a' and 6b' of the side flanges 4a and 4 b may be bent outwards as in Fig. 7. This is used where a maximum of space is needed around the terminal lugs 3, while retaining the rigidity derived from the bent ends of the side flanges.
  • bus bars according to the invention may conveniently be manufactured by folding and punching copper or aluminium strip in a manner which is well-known in metal-working.
