Definitions

  • the invention relates to a battery terminal connector having a housing of insulating material and with a terminal post hole to receive a battery terminal post as well as a cable hole which is preferably substantially perpendicular to the terminal post hole and serves to receive a contact device to establish connection between a battery cable and the terminal post and which extends through a threaded stub on the housing, said contact device being slidable in the cable hole and capable of being pressed against a terminal post in the terminal post hole by means of a nut or a threaded bushing of insulating material, said nut or threaded bushing being screwed on to or into the threaded stub and having an inwardly extending flange which cooperates with a substantially radial face on the contact device.
  • Such a battery terminal connector can be manufactured at a relatively low price because both the housing and the nut or the threaded bushing can consist of an inexpensive plastics material, e.g. acetal plastics.
  • all the conducting parts of the applied terminal connector are enclosed by insulating material, which makes it impossible to connect a starter cable without first removing the terminal connector.
  • it has been proposed to overcome this drawback by providing the housing or a sleeve member corresponding to the threaded stub with an opening which is normally covered by a detachable or hinged cover, which may have the form of a clamp. Such a feature complicates the entire structure and adds to the cost.
  • the object of the invention is to provide a battery terminal connector of the present type which, without any noticeable increase in the cost, allows a starter cable to be connected to the applied terminal connector.
  • the contact device has a rearwardly extending conducting element which, in the applied position of the battery terminal connector, protrudes through the nut or the threaded bushing and over a portion of the cable insulation.
  • the projecting portion of the contact device is directly accessible for connection of a starter cable, and the additional cost involved is just the material of the extension.
  • the conducting rearwardly extending extension can expediently be constructed as stated in claim 2.
  • the conducting, rearwardly extending extension can be strip-shaped, likewise as stated in claim 3.
  • the nut or the threaded bushing is formed with two or more preferably axial legs which extend rearwardly at least to the rear end of the preferably tubular extension of the contact device.
  • the legs form a convenient finger grip for screwing on and off the nut, just as they permit the use of pliers or wrenches for tightening or loosening the nut, when said nut is not hexagonal, but cylindrical.
  • the numeral 10 represents a substantially frustro-conical battery terminal connector housing which has a lateral extension 11 and consists of insulating material, e.g. a suitable, strong plastics material.
  • the housing has a terminal post hole 12 to receive a battery terminal post 13 shown in broken lines and a cable hole 14 which is substantially perpendicular to said post and extends through the lateral extension 11 and through an exteriorly threaded pipe stub 15 which is integral with the extension.
  • the cable hole 14 slidably receives a contact device consisting of two members, viz. a cylindrical contact element 16 and a sleeve 17, both made of lead or alloyed lead.
  • the front end face 18 of the contact element 16 has a cone surface shape corresponding to the shape of the battery terminal post.
  • the contact element On the rear end face 19 the contact element has a conical tip 20.
  • the front end of the sleeve 17 is formed with an inner conical face 21, and the sleeve has an outer annular flange 22 somewhat spaced from both ends.
  • the nut 23 has moreover two rearwardly extending legs 28 which, in the applied position of the terminal connector as shown in fig.
  • a battery cable with an insulating sheath 25 whose end portion is stripped, is mounted in that the exposed threads 26 - after the nut 23 and the sleeve 17 have been pushed over the cable - are pressed over the conical tip 20 of the contact element 16 so that the threads will be spread and distributed over the surface of the tip.
  • the sleeve 17 is now pushed forwardly over the threads, and the nut 23 is screwed on to the stub 15 and tightened so that the cable threads will be fixed between the conical face 21 of the sleeve 17 and the conical face of the contact element 16, and the contact element 16 will be clamped against the terminal post 13.
  • the conductive sleeve 17 can optionally be replaced by such a sleeve 29 of insulating material as is shown in figs. 3-5.
  • This sleeve is constructed in the same manner as the sleeve 17, except that its inner wall is formed with an axial throughgoing groove 30 to receive such a metal strip 31 as is shown in fig. 6, and that it has a cut-out 32 at its outer end adjacent the groove 30.
  • the metal strip 31 is of such length as to extend through the cut-out 32 and a distance beyond the rear edge of the sleeve so that it is readily accessible for connection of a starter cable.
  • the battery terminal connector of the invention may be designed in many other ways than those shown and described in the foregoing.
  • the contact device might be made in one piece and moulded around the exposed thread ends of the cable.
  • the pipe stub 15 might be internally threaded instead of externally, and in that case the nut 23 would be replaced by a threaded bushing with external threads.
  • the rearwardly directed extension 27 of the sleeve 17 does not have to be tubular, but might optionally be slitted or just consist of one or more rod-shaped or strip-shaped parts.
  • the rearwardly extending legs of the nut may be formed in a manner other than the one shown in the drawing, and more than two such legs may be provided.
