Definitions

  • This invention relates to electrical connectors, and more particularly to electrical connectors having female terminals received in cavities of a connector housing.
  • connector housings having flexible locking tangs or fingers are large and bulky, and are difficult to tool and injection mould.
  • Another disadvantage of these devices having flexible locking tangs or fingers is that the system provides only a flexible locking member engaging a rigid locking member. Unfortunately, the flexible locking member may become inadvertently disengaged, allowing the female terminal to be removed from the connector body.
  • An electrical connector in accordance with the present invention comprises a connector housing including a main body and an insert, the main body having a front face, a rear face, and a plurality of terminal receiving cavities extending in a longitudinal direction between the front and rear faces, each terminal receiving cavity being defined in part by opposed side walls, and a flexible beam which is attached at a first end to the front face and at a second end to the rear face and which has a rigid locking tab extending into the terminal receiving cavity, the insert having a planar front portion positioned adjacent the front face and an arm portion which makes a sliding fit in a direction substantially perpendicular to the longitudinal direction in a slot in the main body, the slot opening through the front face and into each terminal receiving cavity on a side opposite to the flexible beam, the arm portion defining a rigid side of each terminal receiving cavity and having a rigid locking tab extending into each terminal receiving cavity; and a female electrical terminal positioned in one of the terminal receiving cavities and having a recess for receiving the locking tab on the flexible beam in a snap fit,
  • the electrical connector of the present invention is simple in design, allows easy manufacture of both the housing and the terminals, and provides a rigid to rigid locking feature for the terminal.
  • an electrical connector 10 includes a connector housing 12 having a main body 11 with a plurality of terminal receiving cavities 14 formed therein, and an insert 15.
  • the main body 11 includes a front face 16 and a rear face 18, and each terminal receiving cavity 14 extends between the front and rear faces in a longitudinal direction A.
  • the rear face 18 has a plurality of openings 20, each aligned with a terminal receiving cavity 14 to facilitate insertion of a female terminal 22 into the cavity 14 through the opening 20.
  • Each terminal receiving cavity 14 is defined in part by opposed side walls 26, 28, and a flexible beam 34.
  • the beam 34 preferably has first and second ends 36, 38 attached to the front face 16 and rear face 18 of the main body 11, respectively.
  • the flexible beam 34 is attached only at the ends 36, 38 and not along sides 40 of the beam.
  • a rigid locking tab 42 integral with the beam 34 extends from the beam into the terminal receiving cavity 14.
  • a second cavity 44 may be defined in the main body 11 on the opposite side of the flexible beam 34 to the terminal receiving cavity 14 to facilitate movement or deflection of the beam 34.
  • a slot 17 is formed in the main body 11 and extends in a direction substantially perpendicular to the longitudinal direction A.
  • a groove 35 is formed in the main body 11 and extends in a direction substantially perpendicular to the longitudinal direction A and opens into the slot 17.
  • the slot 17 opens through the front face 16 of the main body 11 and through each terminal receiving cavity 14 on a side of the terminal receiving cavity which is opposite to the beam 34.
  • the insert 15 is substantially T-shaped and has a planar front portion 19 and an arm portion 21 which extends away from the front portion in a direction substantially perpendicular thereto.
  • the arm portion 21 makes a sliding fit in the slot 17 in a direction substantially perpendicular to the longitudinal direction A such that the arm portion defines a substantially rigid side 24 of each terminal receiving cavity 14, and the front portion 19 lies alongside the front face 16 of the main body 11.
  • the front portion 19 has a plurality of openings 64, each aligned with a terminal receiving cavity 14
  • the arm portion 21 has integral rigid locking tabs 30 which extend from the arm portion into each terminal receiving cavity 14 at a location generally opposite the locking tabs 42 formed on the beam 34.
  • the tabs 30 are preferably defined by a rib 23 formed on the arm portion 21 with gaps 25 formed in the rib between adjacent tabs.
  • the main body 11 is constructed and arranged for receiving a female terminal 22 in each of the terminal receiving cavities 14.
  • the female terminal 22 may include a first end 46 and second end 48, and a body portion 50 therebetween.
  • the first end 46 is open to receive a male terminal.
  • the second end 48 is constructed for attachment to a wire 52, and preferably includes a metal crimp section.
  • the body portion 50 has a recess 58 or an aperture formed therein for receiving the locking tab 30, and a recess 27 or an aperture for receiving the locking tab 42.
  • the recesses 58,27 may be connected as shown by a circumferentially extending groove 29.
  • the recess 58 has a rearwardly facing shoulder 60 for engaging a corresponding forwardly facing shoulder 32 on the locking tab 30.
  • the recess 27 has a rearwardly facing shoulder 31 for engaging a corresponding forwardly facing shoulder 33 on the locking tab 42.
  • the arm portion 21 of the insert 15 is slid into the slot 17, with the locking tabs 30 sliding in the groove 35, until the insert reaches a first position where the gaps 25 between the locking tabs 30 align with the terminal receiving cavities 14.
  • the first end 46 of the female terminal 22 is inserted through the opening 20 in the rear face 18 and into the terminal receiving cavity 14.
  • the first end 46 of the female terminal 22 passes through the gap 25 and engages the locking tab 42, and the beam 34 flexes into the second cavity 44 to accommodate the movement of the beam.
  • the female terminal 22 is pushed forward further until the locking tab 42 makes a snap fit in the recess 27 due to the resilient force of the flexible beam 34.
  • the insert 15 is then slid to a final position in which the locking tab 30 is positioned in the recess 58.
  • the respective shoulders 31,60; 33,32 on the recesses 27,58 and the locking tabs 42,30 prevent inadvertent rearward withdrawal of the terminal 22 from the terminal receiving cavity 14.
  • the shoulders 31,32, 33,60 provide a rigid to rigid surface locking feature holding the terminal 22 in this final position.
  • a male terminal (not shown) may be inserted through the opening 64 in the front portion 19 of the insert 15 and into the first end 46 of the female terminal 22 to make an electrical connection therewith.
  • the openings 64 are offset from the terminal receiving cavities 14, and so the front portion 19 of the insert acts as a stop to prevent over insertion of the female terminals 22.
  • the openings 64 in the front portion 19 preferably have a diameter which is slightly smaller than the first end 46 of the terminals 22 so that the front portion also acts as a stop for the terminals when the insert 15 is in the final position.
  • An additional insert (not shown) may be placed in each of the second cavities 44 to substantially prevent unintentional flexing of the beam 34 after installation of a female terminal 22.
  • the terminal receiving cavities 14 which are adjacent in a direction perpendicular to the longitudinal direction A on either side of the slot 17 are mirror images so that the arm portion 21 of the insert 15 simultaneously provides a rigid side 24 for each terminal receiving cavity on either side of the arm portion.
  • additional arm portions 21 may be provided on the insert 15, with additional corresponding slots 17 being formed in the main body 11 of the housing 12.
  • the electrical connector according to the present invention has a low profile, is simple in design, easy to manufacture, and provides a rigid to rigid surface locking feature of the terminal that has previously been absent in prior art designs.
