Definitions

  • a battery terminal is made by stamping from sheet metal and bending to form two aligned holes which fit over a battery terminal post. Each hole is open on one side and has a lug bent from it through which a clamping screw can pass into the base of the terminal. A conductor can be crimped onto an integral ferrule.
  • POST TERMINAL CONNECTOR This invention relates to an electrical connector formed from a single piece of sheet metal and comprising a contact portion for engaging a battery post terminal or the like and an integral ferrule portion for attachment to an electrical conductor.
  • connections to post terminals have customarily been made by sliding a cast sleeve or cap having a longitudinal slit over the post and tightening the sleeve or cap onto the post by a bolt and nut attached to extensions of the edges of the slit to close the edges together.
  • a sheet metal form of connector has also been proposed in which a strip of metal is bent transverse to its length to form a tube and similarly tightened by a bolt.
  • a conductor is secured to an extension of the connector by soldering or brazing.
  • An electrical connector according to the present invention is formed from a single piece of sheet metal and comprising a contact portion for engaging a post terminal and an integral ferrule portion for attachment to an electrical conductor, in which the contact portion is formed by folding the strip into a channel with a base part and two sidewall parts, each sidewall having an aperture with parts adapted to engage a post terminal and each aperture being open to one end of the sidewall, a lug portion of each sidewall adjacent the open end of the apertures being turned in over the base part in an overlapping manner, the overlapping lug portions being adapted for clamping with the base partto reduce the dimensions of the apertures.
  • the invention also includes a blank stamped from strip material for folding into a connector according to the invention, in which the blank comprises a longitudinally extending central base part having arcuate sidewall parts extending on each side, the sidewall parts defining open apertures with the openings to the apertures extending in the longitudinal direction of the central base part, and outwardly extending lug portions projecting from the free ends of the sidewall parts.
  • An object of the invention is to provide a stamped and formed electrical connector for a battery terminal or round ost.
  • Another object is the provision of an electrical connector having inwardly-directed flanges for engagement with a battery terminal or round post.
  • a further object is to provide an electrical connector having serrated surfaces or lips on inwardly-directed flanges to enhance the electrical connection and retention of the connector on a battery terminal or round post.
  • An additional object is the provision of an electrical connector having apertures in sidewalls thereof with the apertures being provided inwardly-directed flanges defining engaging areas for engagement with a battery terminal or round post.
  • Still a further object is to provide an electrical connector having means to tighten and secure a terminal-engaging section onto a battery terminal or round post.
  • FIG. I shows a perspective view of the connector
  • FIG. 2 shows a sectional view of the connector on the lines 2-2 of FIG. 1;
  • FIG. 3 shows a side view of the connector connected to a conductor
  • FIG. 4 shows a blanked strip for forming a connector.
  • the connector comprises two parts 1, 2 stamped from sheet metal.
  • the first part 1 is a crimping ferrule and is secured, in operation, by crimping to a conductor 3 such as a battery lead in a motor car.
  • the other part 2 is adapted to be fitted over a frustoconical shaped terminal post (not shown) of a battery of the car.
  • the ferrule part 1 has inturned sections 4, 5 which fold over onto the conductor 3 to grip it and transverse serrations 25, FIG. 4, which also assist in the gripping action.
  • the sections 4 and 5 may be normally parallel to one another so that ferrule l is U-shape prior to being crimped onto conductor 3.
  • the part 2 is in the form of a channel having a flat central base part 6 with two perpendicular sidewalls 7, 8.
  • the sidewalls 7, 8 each have an enlarged aperture 9, 10 respectively stamped out with respective flanges 11, 12, FIG. 2, turned into the body of the channel.
  • Flanges 11 and 12 are tapered away from their respective sidewalls.
  • the apertures are coaxial and aperture 9 is smaller in diameter than the aperture 10 so that account is taken of the frustoconical shape of the battery post terminal on which it is to be fitted.
  • Each aperture 9 and 10 is open at its side so that there is a slot or opening 14, 15 respectively in each sidewall 7, 8 between the apertures and the ends of the sidewalls.
  • the slots 14, IS in this embodiment open adjacent the ferrule part 1.
  • the sidewalls 7, 8 have lug portions l6, l7 bent over from a part thereof.
  • the two lug portions overlap each other with the lug portion 16 associated with the sidewall 7 having the smaller dimensioned aperture 9 lying beneath the lug portion 17.
  • Each lug portion has an aperture 18, 19 respectively through it and these apertures are in alignment with each other and with an aperture 20 in the base part 6.
  • a slot (not shown) may be provided in base part 6 forward of aperture 20.
  • a clamping bolt 21 is passed through these holes and secured by a nut 22. Tightening of the nut 22 tends to close the slots l4, l5 and to reduce the size of apertures 9, 10.
  • the nut 22 When the connector is to be applied to a post terminal, the nut 22 is slackened off and the connector is slid over the top of the terminal with the sidewall 8 encompassing a thicker part of the frustoconical shape and the sidewall 7 a thinner part thereof.
  • the relative dimensions of apertures 9 and 10 and the overlapping relationship of lug portions 16 and 17 enable the connector to be the right shape initially to fit the post terminal.
  • the clamping nut 22 and bolt 21 With the connector. properly seated, the clamping nut 22 and bolt 21 are tightened until the connector grips the post terminal securely.
  • the flanges 11, 12 of the sidewalls will seat around the post terminal during tightening and thus produce a good electrical contact between their mating surfaces.
  • Flanges l1 and 12 may be provided with inwardly-directed lips for biting into the post terminal to enhance the electrical connection and to prevent any axial slippage or serrations such as serrations 25 on ferrule 1. Slight lips are initially formed at the free ends of the flanges I1 and 12 as a result of the forming operation, however the lips can be larger, if desired.
  • the apertures 9, 10 would be dimensioned appropriately and would each have the same size.
  • FIG. 4 The blanks from which the connectors are folded are shown in FIG. 4.
  • the blanks are stamped out of the strip metal 23, and they are joined to each other by tabs 24 so that after a folding operation the connectors can be rolled and stored in strip form.
  • the tabs are easily broken to separate the connectors.
  • An electrical connector formed from a single piece of sheet metal and comprising a contact portion for engaging a post terminal and an integral ferrule portion for attachment to an electrical conductor, the contact portion including a channel having a base part and two sidewalls, each sidewall having an aperture with a part adapted to engage the post terminal and each aperture being open to one end of the sidewall, a lug portion of each sidewall adjacent the open end of the apertures being turned in over the base part in an overlapping manner, the overlapping lug portions being adapted for clamping to the base part to reduce the dimensions of the apertures.
  • a blank for a tenninal stamped from sheet metal comprising an elongate base portion having a narrow end adapted to define a crimping portion and a wider end adapted to define a contact portion, the base portion at the wider end being formed with a pair of generally circular apertures spaced apart laterally of the base and bounded on outer sides by arcuate wall portions, a pair of parallel open ended slots formed in the blank, each extending from a respective aperture towards the narrower end of the base, free ends of the arcuate wall parts adjacent the slots being formed with outwardly extending lug portions, the base part between the slots and the lug portions having respective holes centered on a common line transverse of the length of the blank between the narrower and wider ends.
