     BACKGROUND OF THE INVENTION 
       [0002]    The present invention generally relates to a method of operating a connector apparatus having a female connector assembly and a male connector assembly. 
       BRIEF SUMMARY OF THE INVENTION 
       [0003]    The present invention generally relates to a method of operating a connector apparatus having a female connector assembly and a male connector assembly. 
         [0004]    The female connector assembly includes a female housing, a connector position assurance (CPA) member for assuring the engagement of the male connector assembly with the female connector assembly, and a first terminal position assurance (TPA) member for assuring that terminals for the female connector assembly are positioned properly. The female housing further includes a connector latch used to securely hold together a connector apparatus. 
         [0005]    The male connector assembly includes a male housing and a second TPA member for assuring that terminals for the male connector assembly are positioned properly. 
         [0006]    The female connector assembly and male connector assembly can be mated together. 
         [0007]    The connector apparatus, having the female housing, male housing, CPA member, first TPA member, second TPA member, and connector latch, provides a number of desirable characteristics, including at least, for example: an audible “click” sound when the female connector assembly and the male connector assembly are mated together, which is an extra loud sound; a low profile connector latch; a resistance to permanent set for the connector latch; a resistance to movement to final lock position for the CPA member, first TPA member, and second TPA member; a moderate amount of reinforcement; mutual retention; good mechanical strength; easy molding features; no secondary operation of a user is required; failure prevention means; and good dimensional control of latching geometry. 
         [0008]    To ensure that the first TPA member is made available for connecting to the female housing during transport thereof, for example, the first TPA is engaged, in a preset position, to the female housing. 
         [0009]    To ensure that the second TPA member is made available for connecting to the male housing during transport thereof, for example, the second TPA is engaged, in a preset position, to the male housing. 
         [0010]    To ensure that the CPA member is made available for connecting to the female housing during transport thereof, for example, the CPA member is engaged, in a preset position, to the female housing. 
         [0011]    At least one terminal can be provided into each of the male connector assembly and the female connector assembly, when the first TPA member and the second TPA member are in the preset position. 
         [0012]    The male connector assembly and female connector assembly are engaged together, and the engagement thereof is assured when the CPA member is placed in a final lock position. 
         [0013]    The set of terminals provided for the female connector assembly is secured thereto when the first TPA member is placed in the final lock position. 
         [0014]    The set of terminals provided for the male connector assembly is secured thereto when the second TPA member is placed in the final lock position. 
         [0015]    It is a desirable trait to have an audible “click” sound for a connector. For example, when components of an automotive connector are completely mated with each other, it is a desirable trait to have an audible “click” sound for convenient assurance that the components are completely mated. In the automotive connector field, an extra loud sound is favorable. It is desirable to have the loudest “click” sound possible. The “click” sound can be achieved by an interaction of latching features, for example. By placing latching features in a preloaded condition, there is additional force when a first connector assembly and a second connector assembly are mated together, and that additional force helps to make the “click” sound louder than it would have been if the latching features had not been in a preloaded condition. 
         [0016]    It is a desirable trait for the connector latch to have a low profile. By manufacturing the connector latch in an undeflected position, the gaps required to create overstress protection features, to prevent the connector latch from being pried in the wrong direction and damaged, are not needed. The gaps can be removed from the overall height of the latch system, so that the connector latch can have a low profile. 
         [0017]    It is a desirable trait to have a resistance to being set. For example, when automotive wire harnesses are bundled for shipment, the connector latches can be unintentionally compressed and held in a deflected position. Especially in hot environments, this condition causes the connector latch to be permanently deflected, also known as permanently set, thus rendering the connector latch useless or less effective. Preloading the connector latch makes the connector latch more resistant to this failure mode. 
         [0018]    It is a desirable trait to have good dimensional control of latching geometry. By preloading the connector latch against dimensionally stable features, the height of the connector latch features can be controlled easily. 
         [0019]    After the connector latch is manufactured, the connector latch is in an undeflected position. The connector latch is then subjected to a pre-mating deflection process, in order to deflect the connector latch and lock the connector latch in a preloaded position. After the pre-mating deflection process has been completed, the connector latch is locked in a preloaded position and can be referred to as a preloaded connector latch. 
         [0020]    When a first connector assembly and a second connector assembly are engaged together, the engagement thereof is assured because the connector latch causes an audible “click” sound. A first connector assembly can correspond to a female connector assembly or other type of connector assembly, for example. A second connector assembly can correspond to a male connector assembly or other type of connector assembly, for example. The undeflected position can also be referred to as an extended and relaxed undeflected position. 
         [0021]    Each TPA member has at least one flexible feature and at least one guide. The flexible feature can also be referred to as a protrusion. The guide can provide proper guidance and avoid any imbalance created during engagement of a TPA member with a housing. 
         [0022]    A CPA member provides a number of desirable characteristics, including at least, for example: it helps to achieve a full potential force of the system and desirable audible “click” sound when the CPA member is inserted into a housing; it helps to avoid a CPA member being moved to a final lock position (or “set” position) during shipping and/or handling; it requires no secondary operation of a user; and it helps prevent failure. 
         [0023]    A TPA member provides a number of desirable characteristics, including at least, for example: it helps to achieve a full potential force of the system and desirable audible “click” sound when the TPA member is inserted into a housing; it helps to avoid a TPA member being moved to a final lock position during shipping and/or handling; it requires no secondary operation of a user; and it helps prevent failure. 
         [0024]    Because of the use of a TPA member having the guide, the TPA member&#39;s first pair of flexible features is more likely to engage substantially simultaneously, and then subsequently the TPA member&#39;s second pair of flexible features is more likely to engage substantially simultaneously, thereby achieving full potential force of the system and producing an audible “click” sound. Because of the guide, there is additional force when a TPA member and a connector assembly are mated together, and that additional force helps to make the “click” sound louder than it would have been if the guide was not present. 
         [0025]    It is a desirable trait to avoid a TPA member being moved to a final lock position during shipping and/or handling. The guide and flexible features of the TPA member help to make the TPA member more resistant to entering a final lock position during shipping and/or handling. The guide and flexible features of the TPA members help to prevent a movement of the TPA members from a preset position to a final lock position during shipping and/or handling. 
         [0026]    It is a desirable trait for a TPA member to avoid a need for a secondary operation of a user. The guide and flexible features of TPA members help to avoid a need for a secondary operation of a user. The desired movement can be accomplished by a single operation of a user. 
         [0027]    It is a desirable trait for a TPA member to help prevent failure. The location/guide features and flexible features of TPA members, according to the principles disclosed herein, help to avoid failure. 
         [0028]    When a TPA member and a housing are engaged together in a final lock position, the engagement thereof is assured because there is an audible “click” sound. 
         [0029]    The connector apparatus of the present invention is at least one part of MSL connector series. 
         [0030]    Additional features, advantages, and embodiments of the invention are set forth or apparent from consideration of the following detailed description, drawings and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanations without limiting the scope of the invention as claimed.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0099]      FIG. 1  is a perspective view of a connector apparatus, in accordance with the principles of the present invention, in a six-pin configuration.  FIG. 1  illustrates a connector apparatus, generally referred to by reference numeral  100 , which includes a female housing  102 , a CPA member  104  in the female housing  102 , a male housing  108 , and a TPA member  110  in the male housing  108 . As shown in  FIG. 1 , the female housing  102  is mated with the male housing  108 . 
         [0100]      FIG. 2  is a perspective view of a connector apparatus, in accordance with the principles of the present invention, in a six-pin configuration.  FIG. 2  illustrates a connector apparatus, generally referred to by reference numeral  200 , which includes a female housing  202 , a CPA member  204  in the female housing  202 , a male housing  208 , and a TPA member  210  in the male housing  208 . As shown in  FIG. 2 , the female housing  2102  is mated with the male housing  208 . 
         [0101]    A full connector assembly consists of a male connector assembly and a female connector assembly. The full connector assembly can also be referred to as a connector apparatus. 
         [0102]    The female connector assembly consists of a female housing, a TPA member, and a CPA member. For female sub-assembly, the TPA member and CPA member are inserted into the female housing in the preset position. 
         [0103]    The male connector assembly consists of a male housing and a TPA member. For male sub-assembly, the TPA member is inserted into the male housing in the preset position. 
         [0104]    The female and male connector assemblies are assembled separately. After inserting terminals in both the female and male connector assemblies, the TPA member is pushed to the final lock position for providing a secondary locking to the terminals. Both sub-assemblies are then mated to make a system assembly. 
         [0105]    The female housing has a connector latch which latches with the male housing to interlock. The CPA member provides an assurance that both female and male connector assemblies are locked. Then the CPA member is pushed to the final lock position. 
         [0106]    The connector apparatus of the present invention includes a number of advantages and improvements. The connector apparatus of the present invention can help to prevent a locking latch from getting damaged/deformed during shipping and handling, and thus can help prevent mating problems. 
         [0107]    The connector apparatus of the present invention can help to prevent a CPA member from getting damaged/deformed during shipping and handling, and thus can help prevent mating problems. 
         [0108]    The connector apparatus of the present invention can help to prevent a TPA member from getting inadvertently pushed into the final lock position during shipping and handling, and thus can help prevent terminal insertion problems. 
         [0109]    The connector apparatus of the present invention can help to prevent a user from needing to engage in secondary operations. 
         [0110]    The connector apparatus of the present invention can help to prevent complaints from a user, because it helps prevent problems associated with an inadvertent movement of a TPA member or CPA member to a final lock position during shipping and/or handling, for example. 
         [0111]    The connector apparatus of the present invention provides an improved connector assembly comprising a female housing and male housing designed to provide a superior audible click sound, moderate reinforcement, mutual retention, good mechanical strength when the female and male housings engage with each other, and extremely easy molding consideration by manufacturing the female housing&#39;s connector latch with overbuild and then pushing the button of the connector latch to a preset position during assembly. 
         [0112]    After the connector latch of the present invention is manufactured, the connector latch is in the extended and relaxed undeflected position. When the connector latch is in that position, the button  902  of the connector latch is extended upward, above a top  410  of a female housing  400 . The button  902  is held up in the extended and relaxed undeflected position by the latch beams  904  and  906 . 
         [0113]    As indicated above, after the connector latch of the present invention is manufactured, the connector latch is in the extended and relaxed undeflected position. The connector latch is then subjected to a pre-mating deflection process, in order to deflect the connector latch and lock the connector latch in a preloaded position. 
         [0114]    After the pre-mating deflection process has been completed, the connector latch is locked in a preloaded position and can be referred to as a preloaded connector latch. 
         [0115]      FIGS. 3, 4A, 5A, 7A, and 8A , for example, show a female housing  400  having a connector latch in accordance with the principles of the present invention, showing the connector latch in a preloaded position. 
         [0116]    The connector apparatus of the present invention can help to provide protection to a TPA member by having TPA protection ribs  416 ,  418 ,  442 ,  444 ,  446 , and  448  around the TPA member on the female housing  400 , for example. Those ribs help to prevent the TPA member from contacting other connectors during shipping and handling, to help reduce the occurrence of set TPA members, for example. That is, the ribs help to prevent TPA members from inadvertently moving from the preset position to the final lock position during shipping and handling, for example. 
         [0117]    The connector apparatus of the present invention can help to provide protection to a TPA member by having TPA protection ribs  740 ,  742 ,  744 ,  746 ,  748 , and  750  around the TPA member on the male housing  700 , for example. Those ribs help to prevent the TPA member from contacting other connectors during shipping and handling, to help reduce the occurrence of set TPA members, for example. That is, the ribs help to prevent TPA members from inadvertently moving from the preset position to the final lock position during shipping and handling, for example. 
         [0118]    The connector apparatus of the present invention can help to provide protection to a CPA member by having CPA protection walls  432 ,  434 , and  436  around the CPA member on the female housing  400 , for example. Those walls help to prevent the CPA member from contacting other components and wiring harnesses during shipping and handling, and help to prevent damage, for example. 
         [0119]    The connector apparatus of the present invention can help to protect foreign wires belonging to an adjacent harness from being caught in components by providing anti-snagging features to the female housing and male housing. 
         [0120]    The connector apparatus of the present invention can help the TPA members and CPA members to stay in the preset position during shipping and handling. 
         [0121]    The connector apparatus of the present invention can prevent a need for a user to engage in a secondary operation such as trying to move a TPA member from a final lock position to a preset position, for example, after the TPA member was inadvertently moved into the final lock position during shipping and handling. 
         [0122]    The connector apparatus of the present invention can prevent a need for a user to engage in a secondary operation such as trying to move a CPA member from a final lock position to a preset position, for example, after the CPA member was inadvertently moved into the final lock position during shipping and handling. 
         [0123]    The connector apparatus of the present invention can help prevent customer complaints, because it helps avoid snags with other cables. 
         [0124]    The connector apparatus of the present invention can help prevent a need for tray packaging.

         [0222]      FIG. 38  is a top elevational view of the male housing  970  of the male connector assembly of  FIG. 34  with a TPA member  960  in the preset position.  FIG. 39  is a perspective view of the male housing  970  of the male connector assembly of  FIG. 34  with a TPA member  960  in the preset position. 
         [0223]      FIG. 34  depicts an aperture for receiving the insertion side (bottom)  962  of TPA member  960 , and  FIG. 39  shows TPA member  960  in that aperture for receiving the insertion side (bottom)  962  of TPA member  960  with the TPA member  960  in the preset position. 
         [0224]      FIG. 40  is a perspective view of the male housing  970  of the male connector assembly of  FIG. 34  with a TPA member  960  in the final lock position.  FIG. 34  depicts an aperture for receiving the insertion side (bottom)  962  of TPA member  960 , and  FIG. 40  shows TPA member  960  in that aperture for receiving the insertion side (bottom)  962  of TPA member  960  with the TPA member  960  in the final lock position. 
         [0225]      FIG. 41  is a side elevational view of the male housing  970  of the male connector assembly of  FIG. 34 .  FIG. 42  is a bottom elevational view of the male housing  970  of the male connector assembly of  FIG. 34 .  FIG. 42  depicts the bottom  982  of the male housing  970 . 
         [0226]    The female housing  920  is mated with the male housing  970  when the rear end  924  of the female housing  920  is received into the aperture  986  of the male housing  970 . The female housing  400  is mated with the male housing  700  when the rear end  404  of the female housing  400  is received into the aperture  734  of the male housing  700 . 
         [0227]    As confirmed by the upper view and lower view of  FIG. 4B , for the preset position, the exposed side (top)  614  of TPA member  600  does not extend away from the female housing  400  beyond the TPA protection ribs  416  and  418 . The TPA protection ribs  416  and  418  protect the TPA member  600  in the preset position, because the TPA protection ribs  416  and  418  extend away from the female housing  400  beyond the exposed side (top)  614  of TPA member  600 . 
         [0228]    The fact that the TPA protection ribs extend away from a female housing beyond the exposed side (top) of a TPA member, in the preset position, is also shown in the lower view of  FIG. 5B , for example. 
         [0229]      FIG. 7B  shows that an outermost edge of TPA protection ribs  446  and  448  of female housing  400  extend further away from the female housing  400  than the exposed side (top)  614 , in the preset position, and thus the TPA member  600  is protected by the ribs  446  and  448 . That is, as shown in FIG.  7 B, an outermost edge of TPA protection ribs  446  and  448  of female housing  400  is lower than the exposed side (top)  614 , in the preset position, and thus the TPA member  600  is protected by the ribs  446  and  448 . The bottom  412  of female housing  400  also extends below the exposed side (top)  614 , as shown in  FIG. 7B , and thus the bottom  412  also helps to prevent the TPA member  600  from inadvertently being moved from the preset position to the final lock position during shipping and/or handling. 
         [0230]    As depicted by  FIG. 13B , for the preset position, the exposed side (top)  614  of the TPA member does not extend away from the male housing  700  beyond the TPA protection ribs  740 ,  742 ,  744 ,  746 ,  748 , and  750 . The TPA protection ribs  740 ,  742 ,  744 ,  746 ,  748 , and  750  protect the TPA member in the preset position, because the TPA protection ribs  740 ,  742 ,  744 ,  746 ,  748 , and  750  extend away from the male housing  700  beyond the exposed side (top)  614  of the TPA member. See also  FIG. 15B . 
         [0231]      FIG. 13B  shows that, for the preset position, the exposed side (top)  614  of TPA member is positioned nearer to the male housing  700  than the outermost edges of the TPA protection ribs  740 ,  742 ,  744 ,  746 ,  748 , and  750 . That is, the outermost edges of the TPA protection ribs  740 ,  742 ,  744 ,  746 ,  748 , and  750  extend above the exposed side (top)  614  of TPA member, in the preset position. This is shown in  FIGS. 13B, 15B, and 1 , for example. Thus, the tops of the TPA protection ribs are above the top of the TPA member, when the TPA member is in the preset position, as shown in  FIGS. 1, 13B, and 15B , for example, and the TPA protection ribs on the male housing help to prevent the TPA member from being bumped inadvertently or pushed inadvertently into the final lock position during shipping and/or handling, for example. 
         [0232]    As shown in  FIGS. 11, 15A, and 15B , for example, the TPA protection ribs  742 ,  744 ,  748 , and  750  are shaped to slope down toward the aperture receiving the TPA member  600 . The sloping surfaces help to guide the TPA member  600  into the aperture in male housing  700 , for example, when a user is first inserting the TPA member  600  into the aperture of the male housing  700 . 
         [0233]    As shown in  FIGS. 34 and 39 , for example, the TPA protection ribs  990 ,  992 ,  996 , and  998  are shaped to slope down toward the aperture receiving the TPA member  960 . The sloping surfaces help to guide the TPA member  960  into the aperture in male housing  970 , for example, when a user is first inserting the TPA member  960  into the aperture of the male housing  970 . 
         [0234]      FIG. 43  is a perspective view of the CPA member  500  of  FIG. 3 . CPA member  500  has a rear upright portion  514 , first side  508 , second side  510 , central beam  504 , front tip  506  of central beam  504 , and front edge  502 . CPA member  500  also has a rear base  512 , as shown in the upper view of  FIG. 5B . A user can push rear upright portion  514  to push CPA member  500  to the preset position and to the final lock position. 
         [0235]    Although the foregoing description is directed to the preferred embodiments of the invention, it is noted that other variations and modifications will be apparent to those skilled in the art, and may be made without departing from the spirit or scope of the invention.
