Definitions

  • the invention relates to circuit protection for batteries connected in an array and more particularly to circuit protection for batteries connected by a solid conductive bar.
  • batteries are typically provided for, among other things, power for the starter motor.
  • the connection between batteries may be made by an electrically conductive cable arrangement, or, as shown in US Patent No. 6,097,173 to Bryant, Jr., by a solid bar, connecting the battery terminals.
  • circuit protection is provided by a fuse mounted in an arrangement of brackets and cables in the load-side cable connecting the vehicle electrical systems to the batteries.
  • Such arrangements are usually complicated, with many parts, which makes installation time consuming.
  • the invention provides a simplified circuit protection arrangement for integration in a solid bar battery terminal connector of the type having at least two apertures to receive the terminals of batteries being connected.
  • a battery connecting bar is provided with two studs, a first stud electrically insulated from the bar and a second stud in electrical contact with the bar.
  • a fuse element is formed as a strip, having tabs extending from opposite ends thereof, the tabs having holes to accept the studs.
  • the fuse element includes a body encased in a protective housing. The fuse element is connected between and in electrically conducting contact with the first stud and second stud.
  • the first stud, electrically insulated from the bar forms a load terminal for the battery arrangement.
  • the first stud may be formed as a threaded stud, which may conveniently be a headed fastener such as a bolt or cap screw, inserted in a hole in the bar and secured thereto.
  • the threaded stud has an insulated shoulder, and securing means includes an insulating spacer or washer between a head of the stud and a bottom side of the bar, and a second insulating spacer or washer between a top side of the bar and a securing nut.
  • the second stud may conveniently by formed as a threaded stud having an insulated shoulder, that is, identical to the first stud, inserted in a second hole in the bar.
  • the second stud is secured to the bar by a first conductive spacer between the head of the stud and a bottom side of the bar, and a second conductive spacer between a top side of the bar and a securing nut.
  • the second stud is thus in electrically conductive contact with the bar.
  • a non-threaded stud may be used with a clamping arrangement to secure the fuse element to the studs.
  • the bar may include an insulating sleeve covering portions of the bar between the apertures for receiving the battery terminals and between the studs.
  • FIG. 1 is a perspective view of an end portion of a battery connecting bar with integral circuit protection in accordance with the invention.
  • Figure 2 is an exploded section view of the assembly of Figure 1, taken along the lines 2-2.
  • FIG. 1 shows a perspective view of battery connecting bar 10 with integral circuit protection 20 in accordance with the invention.
  • the battery connecting bar 10 includes an electrically conductive bar 12. Portions of the bar 10 are covered by electrical insulation 14, which may be a sleeve or sheath disposed on the covered portions. Exposed portions include holes 16, 18 which are configured to receive terminals of batteries arranged in an array to be connected together.
  • Figure 1 shows two holes for the convenience of the illustration and as an example.
  • a battery connecting bar 10 for the invention may alternatively have a number of holes corresponding to the number of batteries to be connected.
  • the assembly 20 includes a fuse element 22 electrically conductively connected between two posts or studs 24, 26 mounted to the bar 10.
  • a first stud 24 is electrically insulated from the bar 10 so that a current path is formed from the bar to a second stud 26 to the first stud 24.
  • the first stud 24 thus provides a fuse-protected load connection to the battery array.
  • FIG. 2 shows the bar 10 in section taken along the lines 2-2 of Figure 1 and the circuit protecting assembly 20 in exploded view.
  • the studs 24, 26 are threaded bolts inserted through holes 28, 30 formed in the bar 10 from a bottom surface 32 of the bar to extend upward from an upper surface 36 of the bar.
  • the heads 25, 27 of the bolts 24, 26 abut the bottom surface 32 of the bar 10, and as such any head shape or configuration capable of abutting the. bottom surface 32 may be used.
  • the first stud 24 is intended to be electrically insulated from the bar 10, and includes an insulated shoulder 40 formed of any suitable electrically insulating material.
  • the shoulder 40 fits inside the hole 28 in the bar 10 to separate and insulate the stud 24 from the bar.
  • An insulating spacer or washer 42 is placed on the stud to insulate the head 25 of the stud 24 from the bottom surface 32 of the bar. If convenient, the shoulder 40 and spacer 42 may be formed as a single piece.
  • the first stud 24 may be formed entirely of electrically non- conductive material, such as ceramic or high heat resistant plastic.
  • the second stud 26 is intended to be in electrical contact with the bar 10.
  • the second stud 26 may be identical to the first stud 24, that is, with an insulating shoulder 50.
  • the second stud 26 may have an electrically conductive shoulder.
  • a spacer 52 of electrically conductive material is placed between a head 27 of the second stud 26 and the bottom 32 of the bar 10 to make contact between the second stud and the bar.
  • the second stud may be permanently formed on the bar, as by welding.
  • the first stud 24 and second stud 26 extend through the respective holes 28, 30 in the bar 10, and stand out from the upper surface 36 of the bar.
  • the first stud 24 is fastened to the bar 10 by an insulating spacer 42 and a threaded nut 60.
  • the second stud 26 is fastened to the bar 10 by an electrically conductive spacer 52 and a threaded nut 60.
  • the holes 28, 30 in the bar 10 may be made square and the shoulders 40, 50 on the respective studs 24, 26, also made with square profile to prevent turning the hole when the nuts are tightened to fasten the studs to the bar.
  • the fuse element 22 is placed on the studs 24, 26 and secured by washers 52 and threaded nuts 60. As the fasteners 60 and washers 52 clamping the fuse element 22 to the studs are electrically conductive, as is the extended portion of the studs, the fuse element 22 forms a normally conductive path between the studs.
  • the fuse element 22 is preferably a fuse body 62 enclosed in a protective housing and having conductive end tabs 64 extending from opposite ends.
  • the end tabs have holes to receive the studs.
  • the MEGA (brand) fuse available from Littelfuse of Des Plaines, Illinois, USA, and the AMG series available from Cooper Bussmann of Chicago, Illinois, USA, are commercially available fuse elements of the configuration described here.
  • the fuse element 22 will have a high amperage rating, for example 400 Amps.
