  • the terminal main body 20 is at least partly inserted into the shell 60 from behind.

  • the both engaging pieces 71 are bent and welding (particularly laser welding) is applied to the leading end parts of the both engaging pieces 71 (particularly substantially parallel to each other) to form the at least one welded portion 72.
  • the both engaging pieces 71 and the base wall 24 of the coupling portion 23 are arranged at a specified (predetermined or predeterminable) distance from each other.
  • the coupling portion 23 is at least partly surrounded by the attached base plate 67, the (both) attached side plate(s) 68 and/or the (both) engaging piece(s) 71 particularly substantially over the entire circumference, whereby loose movements of the coupling portion 23 in the holding space 69 are prevented and/or an upward movement of the coupling portion 23 to come out of the holding space 69 is prevented by the (both) engaging piece(s) 71.
  • the (both) engaging piece(s) 71 is/are positioned and accommodated in the recess(es) 34 while being held in contact with the receiving edge(s) 33.
  • the front end(s) of the (both) engaging piece(s) 71 come(s) into contact with the rear end of the resilient contact portion 22, whereby a forward displacement of the shell 60 relative to the terminal main body 20 is prevented and/or the rear end(s) of the (both) engaging piece(s) 71 is/are held in contact with the front end(s) of the stopper portion(s) 32 to prevent a backward displacement of the shell 60 relative to the terminal main body 20.

  • the terminal fitting 10 is at least partly inserted into the cavity of the connector housing particularly substantially from behind.
  • the locking lance 65 is resiliently engaged with the inner wall of the cavity and the terminal fitting 10 is primarily locked in the cavity.

  • the front end(s) of the (particularly both) engaging piece(s) 71 come(s) into contact with the rear surface of the resilient contact portion 22 when a force acts on the terminal fitting 10 in a pulling-out direction. This prevents the terminal main body 20 from coming out of the shell 60.
  • the retainer particularly is brought to a locking position in the connector housing and/or inserted into the insertion space 75. Then, the retainer is arranged to substantially face the rear surface of the resilient contact portion 22 and the terminal fitting 10 is secondarily locked in the cavity. This reliably prevents the terminal fitting 10 from coming out of the cavity of the connector housing. Further, when the retainer is in a locking state, the lower end of the retainer can be held in flat or surface contact with the contact surface 73 of the (both) engaging piece(s) 71, thereby preventing side portion(s) of the (both) engaging piece(s) 71 from being vertically inclined and, consequently, preventing the rotation of the terminal fitting 10 about an axis in the cavity.
  • the shell 60 is formed with the one or more, particularly the pair of engaging pieces 71 and/or the both engaging pieces 71 particularly are connected to each other with the terminal main body 20 at least partly fitted in the shell 60, thereby holding an assembled state of the shell 60.

  • the engaging piece(s) 71 is/are positioned and at least partly accommodated in the recess(es) 34 formed between the resilient contact portion 22 and the stopper portion(s) 32, displacements of the engaging pieces 71 are prevented and the shell 60 and the terminal main body 20 are reliably held in the assembled state even if a shear stress is applied between the shell 60 and the terminal main body 20.
  • both engaging pieces 71 are welded or soldered to each other by the welded or soldered portion 72, the connected state of the both engaging pieces 71 is reliably held.
  • the both engaging pieces 71 particularly extend substantially parallel to each other, the terminal fitting 10 is prevented from being rotated about the axis in the cavity of the connector housing by the contact of the retainer with the contact surface 73 of the both engaging pieces 71 when being locked by the retainer.
  • a terminal fitting 10 is provided with a terminal main body 20 including a wire connecting portion 21 and a resilient contact portion 22, and a shell 60 to be assembled with the terminal main body 20 to at least partly cover the resilient contact portion 22.
  • the shell 60 is formed with at least one pair of engaging pieces 71.

  • Both engaging pieces 71A are bent at obtuse angles from the upper ends of both attached side plates 68 and extend obliquely downwardly or inwardly toward an attached base plate 67. In other words, the both engaging pieces 71A extend obliquely in a direction away from an insertion space 75.
  • the leading ends of the both engaging pieces 71A are arranged to substantially face each other slightly above a central or intermediate part of a base wall 24 in a width direction.

    Verbinden der Führungsendteile der beiden Eingriffsstücke (71 E, 71 F) miteinander, indem sie zumindest eines über dem anderen platziert werden und das Vorsprungsstück (79) zumindest teilweise in das Eingriffsloch (78) eingesetzt wird.
  12. Verfahren nach einem der vorhergehenden Ansprüche 7 bis 11, wobei die Hülle (60) gebildet wird, eines oder mehrere aufwölbende Stücke (64) zu umfassen, um eine vordere Endöffnung der Hülle (60) dahingehend zu verschmälern, einen graduell abnehmenden Öffnungsdurchmesser aufzuweisen, und zwar durch die jeweiligen aufwölbenden Stücke (64), so dass ein Vater-bzw.
