Definitions

  • the invention relates to improvement in or relating to receptacle terminals.
  • Receptacle terminals each having a structure to terminate an insulated wire on one side of the terminal and a female portion allowing insertion of a mating terminal tab on the other side are known in the art.
  • two female terminal portions 8a' and 8b' are arranged laterally side by side, each including a rising side wall 10' integrally connected to a common base 12' and a curved top wall 13' integrally connected to the rising side wall 10' and having a descending end 11' extending toward the common base surface 12a'.
  • both portions 8a' and 8b' deflect a certain measurable amount.
  • the deflection of the female terminal portion 8a' is measured in terms of the deflection of a selected point B' relative to the deflection of a selected point A' on the descending end 11' of the top wall 13' and the deflection of a selected point C' relative to the deflection of a selected point A'.
  • the deflections of the selected point B' and of the selected point C' are relatively large with respect to that of the selected point A'.
  • the deflections of these selected points are so large that insertion of the terminal tab in the receptacle terminal when it is mounted on a printed circuit board, may affect surrounding parts mounted on the printed circuit board.
  • the prior art problems are solved by providing a receptacle terminal which reduces such deflections of each female terminal portion upon insertion of the terminal tab in the receptacle terminal.
  • the advantageous structural arrangement of the receptacle terminal allowing termination of an insulated wire on one side of said terminal and allowing insertion of a mating terminal tab on the other side of the terminal is achieved by having two female terminal portions arranged laterally side by side, each including a rising side wall integrally connected to a common base and a curved top wall integrally connected to the rising side walls and each having a descending end extending toward the common base.
  • the two female terminal portions are arranged laterally side by side with a gap therebetween, and the descending end of each is curved to extend toward the rising side wall.
  • a receptacle terminal 1 is shown as having one end adapted to terminate an insulated wire 2, and a second end adapted to receive a mating terminal tab 3.
  • the insulated wire 2 is composed of core conductors 2a and surrounding insulation 2b.
  • the end of receptacle terminal to which an insulated wire 2 is terminated has insulation crimping portion 4 with a pair of insulation crimping sections 4a and 4b, and core conductor portion 5 with a pair of core conductor crimping sections 5a and 5b.
  • the insulation and core crimping sections 4 and 5 along with a pair of female terminal portions 8a and 8b, which will be later described, may be made of sheet metal.
  • the insulation crimping sections 4a and 4b are integrally connected to the opposite sides of a base plate 6 and project therefrom upward forming a "U" shaped section to receive the insulated wire 2.
  • the projecting sections 4a and 4b are bent over the insulation 2b of the insulated wire 2 to crimp and anchor it to the terminal as shown in Fig. 1.
  • the opposite core crimping sections 5a and 5b are also integrally connected to the opposite sides of the base plate 6 and project therefrom upward to receive the core conductors 2a.
  • the sections 5a and 5b are bent over the core conductors 2a of the insulated wire 2 to crimp the conductors as shown from Fig. 1.
  • each female terminal portion 8a and 8b is composed of a rising-and-curving portion 10 and 13 integrally connected to either side of a base plate 12 and each having a free end 11 generally descending and extending toward the base plate 12.
  • a tab inlet 15 is defined between the base plate 12 and the descending ends 11 of the adjacent rising-and-curving portions 10 and 13. Insertion of the tab 3 into the tab inlet 15 causes the descending ends 11 of the adjacent rising-and-curving portions 10 and 13 to resiliently deflect and thereby to apply a force to the tab 3 to hold it firmly in place.
  • the description of the structure of terminal 1 so far is the same as for the prior art receptacle terminal 1' shown in Fig. 5.
  • the central feature of the receptacle terminal 1, according to the present invention is that a gap 14 exists between the opposing female terminal portions 8a and 8b before and after mating with tab 3, and that the free end of each female terminal portion extends towards the rising section of the rising-and-curving portion 8a or 8b.
  • the free end 11' of the curved section of each female terminal portion 8a' or 8b' of the prior-art receptacle terminal 1' extends straight towards the surface 12a' of the base plate 12'.
  • each female terminal portion 8a or 8b extends towards the surface 12a of the base plate 12 and, at the same time, is curved toward the rising section 10 of each female terminal portion 8a or 8b, as shown in Fig. 4.
  • Figs. 4 and 5 show selected points at which deflections were measured. Outward deflections in the x- or y-direction caused by insertion of the terminal tab 3 in the tab inlet 15 and 15' are indicated by a preceding positive sign whereas inward deflections in the x- or y- direction are indicated by a preceding negative sign.
  • the receptacle terminal 1 has substantially less deformation than the prior art receptacle terminal 1' upon insertion of the mating terminal tab 3.
  • the maximum internal stresses were determined for two different deflections of Points A and A' of the left female terminal portions 8a and 8a' of the receptacle terminals 1 and 1'.
  • the maximum internal stress was 13.26 kgt/mm2.
  • the maximum internal stress developed in the receptacle terminal 1 of the present invention is substantially smaller 9.18 kgt/mm2 than that in the prior art receptacle terminal 1'.
  • the maximum internal stress developed in the receptacle terminal 1 of the invention is substantially smaller than that in the prior art receptacle terminal 1'. This indicates an even distribution of internal stresses over the female terminal portion in the receptacle terminal according to the present invention. Also, it should be noted that limitation of the maximum internal stress in the vicinity of the free end 11 of each female terminal portion of a receptacle terminal according to the present invention has the effect of suppressing its outward deflection.
  • each female terminal portion 8a, 8b is directed toward the upwardly projecting section 10 of the female terminal portion. This has the effect of suppressing the outward deflection of the female terminal portion upon insertion of the terminal tab in the receptacle terminal.
