Abstract
Provided is a connector designed for double retention of a terminal fitting, which inhibits flexure of a flexible lance retaining the terminal fitting by pushing a front holder from a temporary retention position into a full retention position. The connector includes at least any one of abutting planes of a retaining protrusion and a retention arm performing temporary retention of the front holder, as an element to strengthen retention when pushing force is applied to the front holder. Specifically, said abutting plane is formed as an inclined plane with an angle in a direction of generating bites upon application of pushing force. And the connector is designed to effectuate release of retention by means of inserting a retention release jig from a front side of the connector housing.
Claims18
An electrical connection assembly, comprising:
- a housing body having a front side and a back side, the housing body adapted to receive a terminal fitting from the back side;
- a holder adapted to engage the housing body from the front side, the holder having a temporary retention position relative to the housing body and a full retention position relative to the housing body;
- a retention arm provided on one of the housing body and the holder, the retention arm having a end portion;
- a temporary retention means for engaging the retention arm to retain the holder in the temporary retention position;
- a full retention means for engaging the retention arm and prohibiting the holder from moving to the full retention position, wherein the full retention means includes a surface portion configured to abut a surface portion of the end portion so as to form orthogonal abutting surfaces;
- and
- a flexible arm provided on one of the housing body and the holder, the flexible arm adapted to engage the terminal fitting.
An electrical connection assembly, comprising:
- a housing body having a front side and a back side, the housing body adapted to receive a terminal fitting from the back side;
- a holder adapted to engage the housing body from the front side, the holder having a temporary retention position relative to the housing body and a full retention position relative to the housing body;
- a retention arm provided on one of the housing body and the holder, the retention arm having a end portion;
- a temporary retention means for engaging the retention arm to retain the holder in the temporary retention position;
- a full retention means for engaging the retention arm and prohibiting the holder from moving to the full retention position, wherein the full retention means includes an inclined surface portion configured to abut an inclined surface portion of the end portion and urge the end portion and retention means into a more secure engagement upon movement of the holder toward the full retention position;
- and
- a flexible arm provided on one of the housing body and the holder, the flexible arm adapted to engage the terminal fitting.
An electrical connection assembly, comprising:
- a housing body having a front side and a back side, the housing body adapted to receive a terminal fitting from the back side;
- a holder adapted to engage the housing body from the front side, the holder having a temporary retention position relative to the housing body and a full retention position relative to the housing body;
- a retention arm provided on one of the housing body and the holder, the retention arm having a end portion;
- a temporary retainer disposed between the housing body and the holder, the temporary retainer adapted to engage the retention arm and retain the holder in the temporary retention position;
- a full retainer disposed between the housing body and the holder, the full retainer adapted to engage the retention arm and retain the holder in the full retention position, the full retainer having a surface portion adapted to abut a surface portion of the end portion of the retention arm so as to form an engagement with the end portion when the holder is in the temporary position prohibiting the holder from moving to the full retention position.
