  • This invention relates generally to battery terminals of the type used in automotive applications, and, more specifically, to a battery terminal which can be secured to a battery post without external tooling and which is substantially resistant to battery acids relative to prior art battery terminals.
  • Battery terminals of the prior art have required tooling for tightening a nut and bolt forming a part of the battery terminal device for tightly securing the battery terminal to the battery post.
  • Such prior art battery terminals have also normally been corrodable due to battery acids which come in contact with the battery terminal and which are easily terminal due to oxygen in the air and otherwise.
  • a battery terminal which requires no tooling for installation and which is relatively resistant to battery acids as compared with prior art battery terminals.
  • a battery terminal which is formed from or plated with a material which is electrically conductive but-also resistant to the battery acids. Tin, a tin-lead combination or lead itself can be used in such devices.
  • the battery terminal includes a terminal lug having a frusto-conically shaped portion which is inwardly tapered and has vertically disposed slots therein extending to but not through the upper surface of the lug and has a threaded exterior. As an alternative, the said slots may be disposed at an angle to the vertical.
  • the interior of the frusto-conical portion is cylindrical with an inward taper of substantially the same or slightly smaller diameter than the battery post which is to be used therewith to provide a wiping action between the terminal and post during installation.
  • the battery terminal of the present invention also includes a cap which is formed from an insulating material which is also resistant to battery acids such as nylon or the like.
  • the cap is internally threaded for mating with the threads of the frusto-conical portion whereby, due to the slots in the frusto-conical portion, threading of the cap onto the exterior threads of the frusto-conical portion forces the frusto-conical portion inwardly to provide a tight fit between the frusto-conical portion and the battery post.
  • FIG. 1 is a sectional view taken through a connection between a battery terminal and a battery post;
  • FIG. 2 is a perspective view of a battery terminal in accordance with the present invention.
  • FIG. 2A is a perspective view of alternative cap constructions.
  • FIG. 3 is a sectional view taken along the line 3-3 of FIG. 2.
  • a battery terminal I having a wire barrel portion 2 with a terminal lug portion 4 coextensive and integral therewith.
  • the terminal lug portion 4 has a generally central opening and a frusto-conical sleeve portion 6 extending upwardly in the central portion thereof and tapered slightly inwardly toward the top region thereof.
  • the portion 6, which may be formed by standard metal drawing techniques, includes slots or notches 8 therein and an outward threaded portion 10. The slots 8 are made to extend downwardly into the upper surface of the lug portion 4,
  • the battery terminal member 1 is formed from an electrically conductive material having maximum resistance to corrosion to the normal battery acids. Terminals of this type would have a substantial portion of tin, tin and lead or lead.
  • a cap member or enclosure cap 12 having a hollow interior portion and having threads 14 in the interior portion for mating with the threads 10.
  • the threaded portion 14 of the cap 12 can be tapered inwardly toward the more interior portions of the cap member to provide an inward compression of the frusto-conical portions 6 when threadedly engaging the cap 12 with the terminal member 1.
  • the cap 12 can also include gripping ears 22, shown in phantom in FIG. 2A, or grooves 24 at the rim of the cap, as an aid in installation if desired.
  • the battery terminal member 1 is first secured to a battery cable 16 as shown in FIG. 1 by crimping the wire barrel 2 thereof to the battery cable 16.
  • the frustoconical portion 6 of the battery terminal 1 will be placed over a battery post 18 with the frusto-conical portion 6 abutting the post 18.
  • most battery posts 18 have an inward taper which is substantially the same as the inward taper of the frusto-conical portion 6.
  • the frustoconical portion 6 is of a slightly smaller diameter at its top region than the post 18 so that it frictionally engages the post along the periphery of the post and provides a wiping action therewith.
  • the cap 12 is then threaded on to the frusto-conical portion 6 during which time the slotted segments of the frusto-conical portion 6 are forced inwardly into tight mechanical and electrical engagement with the post 18.
  • the lug 4 and barrel 2 are elevated above the surface of the battery. This is provided by adjusting the upward length of the frustoconical portion 6 and the size of the aperture within the cap 12. This arrangement insures that the battery terminal will not become short circuited against the battery holder.
  • the interior of the portion 6 can have burrs or the like thereon to score the post 18 during installation and provide even better electrical connection.
  • the battery terminal in accordance with the present invention is highly resistant to corrosion due to the battery acids, not only in view of the materials used as shown hereinabove, but also because the cap 12 will extend downwardly over the frusto-conical portion 6 to abut its rim against the lug member 4. In this way, and because the slots 8 do not extend entirely through the lug member 4, but bottom at 20 as shown, oxygen from the air will have difficulty in circulating into the recess between the battery post 18 and the interior of the cap 12, thereby providing a poor atmosphere for any oxidation or other chemical reaction to take place.
  • a battery terminal lug connector having selected parts thereof enclosed and protected from corrosive atmosphere, comprising:
  • an electrically conductive lug member having opposed surfaces and provided with a single generally central opening therethrough
  • a frusto-conical externally threaded sleeve portion attached at one end thereof to one of said opposed surfaces of said lug member, said sleeve portion in encircling relationship with respect to said central opening of said lug member,
  • said lug member being fabricated from a corrosion resistant material protecting said lug member from corrosive at mosphere
  • said sleeve portion being fabricated of an electrically conductive material
  • said enclosure cap having a rim abutting on said one opposed surface of said lug member with said cap and said lug member cooperating to enclose and cover said sleeve of conductive material and the entire length of each of said notches with corrosion resistant material for protecting said sleeve from contact with corrosive atmosphere.
