Definitions

  • the present invention relates to a female terminal of the ribbed type and, in particular, to a ribbed terminal having a pin lead-in portion.
  • a terminal is used in a connector which is manufactured and sold by E. I. Du Pont de Nemours and Company, Incorporated under the Trademark RIB-CAGETM.
  • This terminal has a central spine from which extends one or more pairs of cantilevered beams.
  • the beams in each pair may be angled forwardly or rearwardly (that is, toward or away the input end of the terminal) and are formed into a structure generally reminiscent of a human rib cage.
  • the ribbed structure defines a generally enclosed opening.
  • the terminal is itself received in a cavity formed in a housing.
  • the housing may have chamfered lead-in portions which serve to guide a pin into the cavity and into the opening defined by the rib cage.
  • Figure 1 graphically illustrates the magnitude of pin insertion force as a function of insertion distance into a connector having a ribbed terminal, wherein the terminal has two bridged pairs of rearwardly extending ribs. The insertion distance is measured with respect to a reference line R that extends perpendicular to the axis of the opening of the terminal and which contains the forward most extremity of the terminal. The location of the reference line R for a connector having a ribbed terminal therein is shown in Figure 9.
  • a contact lag distance (Distance A, extending from the reference line R to the point di on Figure 1).
  • the contact lag distance is the distance the pin must be displaced inwardly from the reference line R until a portion of the pin (in the case of the prior art terminal, a portion of the tip of the pin) first encounters the ribs of the terminals. This point marks the location where continued forward displacement of the pin would begin to open the ribs.
  • the major portion of the pin remains on the outside of the terminal opening during an initial phase of insertion (Distance B, between the points di to d2 ).
  • the insertion force during this phase acts to spread apart the ribs of the terminal, but owing to the relatively poor pressure angle that the tip of the pin occupies with respect to the ribs a relatively high peak insertion force is required before the cage is spread sufficiently to accommodate the pin. Since this force is transmitted to and resisted by the spine of the terminal the column strength of the spine must be of sufficient to withstand this force without buckling. Moreover, if the spine is made thicker or wider it becomes less flexible, thus limiting its ability to move within the housing to accommodate normal misalignments between the pin and the terminaL
  • the level of insertion force required to insert the pin should be relatively constant and is related primarily to the friction force between the pin and the ribs of the terminal (Distance C, between points d2 to d ⁇ on the graph of Figure 1). It should be noted that during the peak insertion force is reached the plot of insertion force versus distance would be expected lo drop precipitously, as indicated by the cross portion of the trace in Figure 1. However, in practice it may occur that the spine may bend and disorient the terminal within the connector housing. Due to this disorientation a higher than expected insertion force may be required in the Distance C, as is indicated by the solid line on the graph of Figure 1.

  • a specific example of the manner in which the minimum throat dimension Tmin may be ascertained is now set forth.
  • the dimension D of the opening 40 is defined as the minimum distance, measured when a rib 16 is in the relaxed state, between the inner surface of the spine 12 and the point of intersection 55 of that rib and the full diameter major portion M of a pin P inserted into the opening 40, with the axis PA of the pin P being offset from the axis

  • the axis P of the pin P may lie anywhere within a predetermined zone 65 of possible locations within the plane in which the throat T is measured (i.e., the plane of Figure 3) and still obtain the advantages of reduced insertion force.
  • the magnitude of the angle 56 between the reference plane 58 and the surfaces 52 is dependent upon a number of practical design considerations.
  • the surfaces 52 must have a minimum angle that is great enough such that no part of the tip of the pin will touch any portion of the surface 52 before the full diameter portion of the pin engages the surface 52. This limitation will guarantee that the full diameter (or diagonal) of the pin acts on the surfaces 52 and the insertion force imposed on the pin acts radially thereof. If too small an angle is selected the required insertion force will approach an undesirable peak on pin entry. If too large an angle is selected the wipe of the terminal would be adversely affected. These considerations militate that an angle in the range from twenty-five to thirty degrees is preferred.
  • each of the ribs 16 is angled rearwardly on the spine 12. Accordingly, to define the surfaces 52 on such ribs it is preferred that each of the ribs 16 has the tab 50A, 50B, respectively, provided thereon at the end portions 34 thereof.
  • the provision of the tabs 50 has the effect of increasing the beam length of the ribs, which is advantageous in that it effectively decreases the spring constant of the ribs as the pin contacts the tabs as the pin enters the terminal.
  • the ribs 16 were angled forwardly on the terminal 10 the necessity of the tabs 50 would be obviated. If one assumes, for example, that the location of the input end of the terminal were reversed, the ribs 22 as shown in the Figures would, In such an event, define the leading pair of ribs. The surfaces 52 would then be defined on the ends of the ribs generally in the location indicated by the dashed lines 52A', 52B'. In practice, then. for the preferred configuration of rearwardly extending ribs, the tabs 50 add the necessary material at the ends 34 of the ribs on which to place the surfaces to define the lead-in for the pin in accordance with the invention. However, providing forwardly extending ribs may be useful in defining a lead-in at the opposite end of the terminal 10, thereby making the terminal adaptable to accept pins from either or both axial ends thereof.

  • the tab on the rearward rib in the pair would be made longer than the tab on the forward rib in such a pair.
  • forwardly extending ribs are axially offset, and if it is desired that the leaded tips of the ribs on each side of the spine align with each other along the axis 40A, the rearward one of the ribs would be provided with a tab.
  • the tips of the ribs not align with each other, whether the ribs are forwardly or rearwardly extending and whether or not the ribs are axially offset. It is believed that all of the alternatives set forth in this paragraph, or any other configuration which would impart some asymmetry to the configuration of the terminal, are not to be preferred, since such configurations would impart asymmetric forces to the terminal. However, such configurations to the extent that they include a pin lead-in portion, are to be construed as encompassed within the contemplation of the present invention.
  • the contact lag distance (Distance A , between the reference line R and the point d' ⁇ ) is shorter than in the case of the prior art terminal, owing to the forwardly extending tab. It is noted that in the instance for the terminal in accordance with the present invention the contact lag distance is the distance from the reference line R at which the major portion M of the pin P first contacts the material of the terminal. As the pin is inserted into the terminal 10, during an initial insertion phase (Distance B', between the point d' ⁇ and the point d * 2 ) the insertion force required is less than that required by the prior art ribbed terminal.
