Definitions

  • the present invention relates to an electrical terminal structure specifically designed for coupling to a terminal of a motor vehicle battery.
  • the terminals to be coupled to the terminals or poles of a motor vehicle battery generally consist of an electrically conductive material body which, at one end portion thereof, is provided with jaw elements adapted to substantially encompass the battery terminal and to be clamped thereon by means of a threaded tie rod joining the terminal portions or jaws.
  • the terminal is clamped with a given force on the battery terminal by screwing on said threaded tie rod along a direction which is substantially perpendicular to the battery terminal.
  • the task of the present invention is to overcome the above mentioned drawbacks by providing an electric terminal structure, specifically designed for coupling to a motor vehicle battery terminal, which may be accurately clamped on the battery terminal, so as to provide very good electrical contact characte­ristics, with simple and quick clamping operations.
  • a main object of the present invention is to provide such an electric terminal structure which can also surely and quickly disengaged by the battery terminal.
  • Another object of the present invention is to provide such an electric terminal structure which can be made starting from a stamped metal sheet and is very reliable and has a comparatively low making cost.
  • Yet another object of the present invention is to provide such an electric terminal structure which can be easily made starting from easily commercially available elements and materials.
  • an electrical terminal structure specifically designed for coupling to a terminal of a motor vehicle battery, characterized in that it comprises an end piece defining body for coupling to at least an electric cable and an essentially circular seat adapted for coupling to a battery terminal and means for clamping said body on the battery terminal, consisting of a small block having at least a portion thereof flush arranged in said seat and effective to be displaced with respect to said body for changing the clamping force of said battery terminal.
  • the electric terminal structure specifical­ly designed for coupling to a motor vehicle battery terminal which is overally indicated at the reference number 1, comprises a body 2 which is advantageously made of a brass stamped sheet, either pretinned or copper treated.
  • the body 2 is provided, at one end thereof, with an end piece 3 which is so shaped so as to clamp an electrical cable, in the case of an electrical terminal to be coupled to the negative terminal of a battery, or two electrical cables 4 and 5, if the electrical terminal must be coupled to the positive terminal of the battery, as shown in fig.6.
  • the cables 4 and 5 are respectively used for operating the starting motor of the vehicle and for illumination and other purposes.
  • the body 2 At its other end the body 2 is provided with a slightly frustum of cone shaped seat 6 for coupling with the terminal 7 of the battery of a motor vehicle.
  • the body 2 defines a cavity 10, open to the seat 6 and restrained, at the other end, by a slanted abutment member 11.
  • the locking or clamping means for locking the body 2 on the terminal battery 7 said locking or clamping means practically consisting of a small block 15 which has its shaped end 16 flush arranged in said seat 6 and adapted for contact engaging the battery terminal 7.
  • a coupling slanted abutment member 17 which acts, by contact, against the slanted abutment member 11.
  • the small block 15 may be displaced parallely to the battery terminal 7, so as to change the clamping force exerted on the battery terminal.
  • the displacement of the small block 15 toward the attaching zone of the battery terminal 7, for engag­ing the coupling slanted surface 17 and abutment member 11, also provides a clamping force component in the radial direction of the battery terminal, thereby providing a firm clamping and locking of the body 2 on said battery terminal 7.
  • the displacement of the small block 15 is carried out by a bolt 20 the head 21 of which is accessible at the top portion of the electric terminal, said bolt rotatably engages a nut 22 which is affixed at the central portion of the body 2.
  • the clamping of the electric terminal on the battery terminal is carried out by a bolt substantially parallely arranged with respect to the axis of said battery terminal: thus it will be easily accesible for operation.
  • the locking or clamping force is derived from the radial pushing force exerted on the small block 15, toward the battery terminal 7, because of the coupling between the slanted coupling surface 15 and the abutment slanted member 11, thereby always providing an accurate and quick locking.
  • an electric terminal structure which may be easily made starting from a sheet metal and which provides a sure electrical contact owing to the radial clamping force exerted as the small block 15 is displaced.
  • the electrical terminal may be easily and quickly disengaged from the battery terminal since, during the disengagement step, said small block is simply upwardly displaced thereby cancelling the clamping force on the battery terminal.
  • the used materials provided that they are compatible to the intended use, as well as the contingent shapes and size, may be any according to requirements.
