Definitions

  • the present invention relates to a connector which is particularly useful for the guided insertion of electrical connection terminals.
  • female terminals for extraction-resistant electrical connections are currently widely used; such terminals are substantially constituted by a longitudinally elongated metallic plate-like body formed by blanking and plastic deformation from a strip.
  • the plate-like body commonly has a first end which is shaped so as to form connection means for an electrical cable, while a second end thereof, arranged opposite the first one, is shaped by folding inwards part of the longitudinal edges so as to form a seat which, in association with the central region of the body, which is blanked so as to assume the shape of a cantilevered leaf spring and is provided with retention means, is adapted to accommodate a male tab which, once inserted, is locked by said retention means.
  • connection between the female terminal and the tab is conveniently associated with a connector constituted by a hollow body made of plastics, which is adapted to protect and guide the electrical connection between the two parts.
  • the operator is usually unable to easily determine the insertion direction of the female terminal and this, especially in case of forcing, can lead to incorrect electrical connections which, in the worst cases in which the extraction-preventing means have been activated, entail replacing the female terminal and possibly the tab as well.
  • Damage to the female terminal or to the male tab is particularly troublesome, not because of their intrinsic value but because especially with partially or fully automated wiring it can stop production processes which instead require high production rates.
  • EP 0 652 607 discloses a connector comprising a longitudinally elongated hollow body made of plastics which has, at one end, a first opening for the insertion of a female terminal and, at the other end, a second opening for the insertion of a male tab for electrical connection.
  • Such connector has a lance which, because of its elasticity, do not prevent from incorrectly inserting the female terminal into the connector.
  • US Patent no. 4, 050, 757 which is considered as closest prior art, discloses an insulating casing for electrical spade terminal sockets whereby the casing can be slid onto the socket only in a single correct alignment.
  • the aim of the present invention is to provide a connector which solves the above-mentioned problems of commercially available connectors, particularly ensuring that the operator has unambiguous conditions as regards the insertion orientation of the female terminal, in order to obtain an electrical connection which is correct every time, possibly preventing any error of the assembly operator from damaging the components of the wiring.
  • an object of the present invention is to provide a connector which has a structure that can be manufactured at low costs thus being competitive with respect to conventional connectors.
  • a further object of the present invention is to provide a connector which is also adapted to ensure the extraction-preventing characteristic of the female terminal once it has been inserted correctly.
  • a further object of the present invention is to provide a connector which allows a quick and simple connection which can optionally be automated.
  • a further object of the present invention is to provide a connector which ensures high flexibility in application.
  • a further object of the present invention is to provide a connector which can be manufactured with conventional means and technologies.
  • a connector particularly for the guided insertion of electrical connection terminals is generally designated by the reference numeral 10 in a first embodiment.
  • the connector 10 comprises a hollow body 11, which in this case has a substantially rectangular cross-section, is made of plastics and is provided at one end with a first opening 12 for the insertion of a female terminal 13 which is substantially constituted by a conveniently shaped metallic laminar body.
  • the body 11 has, at its other end, a second opening 14 for the insertion of a metallic male tab 15 for electrical connection to the terminal 13.
  • the connector 10 as described in greater detail hereinafter, has an internal surface which is shaped so as to form at least one barrier which determines unambiguous conditions for the insertion orientation of said female terminal 13.
  • a wing 16 protrudes from the internal surface of the body 11 and is shaped so as to form a polarization barrier which is constituted by a tooth 17 protruding from the cantilevered free end of said wing 16.
  • the wing 16 is formed substantially monolithically with respect to the body 11 and can flex elastically, so as to allow the passage of the female terminal 13 only when it is inserted with the correct orientation.
  • the wing 16 protrudes substantially at an angle with respect to the base surface in a direction which corresponds to the insertion direction of the female terminal 13 so as to define, at its free end, extraction-preventing abutment surfaces 18 for said female terminal 13.
  • the body 11 has, in this embodiment, a first portion 19 for the insertion of the female terminal 13 which has a larger cross-section than a second portion 20 which accommodates the connection between the latter and the male tab 15.
  • the wing 16 protrudes substantially at the region where connection between portions 19 and 20 occurs, and more precisely in the region of a recess 21 which actually forms the connection between said portions.
  • the body 11 is further shaped, at the second opening 14, so as to form folded edges 22 which are adapted to form stroke limits for the insertion of the female terminal 13.
  • a connector particularly for the guided insertion of electrical connection terminals is generally designated by the reference numeral 100 in a second embodiment.
  • the connector 100 is not substantially different from the connector 10 since it comprises a hollow body 101 provided with a first opening 102 and a second opening 103 which lies opposite the preceding one; a female terminal and a male tab, not shown in the figures, for electrical connection can be inserted respectively in said openings.
  • the connector 100 also is provided with a wing 104 from which there protrudes, at its free end, a tooth 105 which is adapted to determine the unambiguity of insertion orientation of the female terminal.
  • the connector 100 differs from the connector 10 substantially in that the wing 104 lies opposite the blending region, nowdesignated by the reference numeral 106, between the first portion and the second portion, now designated by the reference numerals 107 and 108 respectively.
  • the operator realizing his error immediately because he cannot complete insertion, can in fact just as quickly correct said error by pulling out the terminal and inserting it again in the opposite orientation.
  • the connector according to the invention in addition to ensuring a safe insertion orientation of the female terminal, also ensures that the female terminal does not disengage once the electrical connection has been performed correctly.
  • the structure of the connector according to the invention can also be advantageously used to prepare automated wiring.
  • the materials and the dimensions may be any according to requirements.
