Abstract
A lever-type connector (F) includes a housing (10) having a wire bundle (27) drawn out from a wire draw-out surface (13). Guide grooves (36) formed in arms (31) of a lever (30) and are configured to guide support shafts (26) of the housing (10) to bearing holes (34) of the arms (31) when assembling the lever (30) with the housing (10). Retracted portions (39) are formed in the guide grooves (36) an are configured to allow an operating portion (32) to be displaced away from the wire bundle (27) when assembling the lever (30) with the housing (10).
Claims7
A lever-type connector, comprising:
- a housing having a support shaft formed on an outer side surface, a wire bundle being drawn out from a wire draw-out surface;
- a lever including an arm, the arm being formed with a cam groove;
- an operating portion extending from an outer peripheral edge of the arm, the operating portion being configured to be displaced to approach the wire draw-out surface when assembling the lever with the housing;
- a bearing hole formed in the arm at a location spaced from the cam groove, the bearing hole rotatably supporting the lever with respect to the housing by being fit to the support shaft;
- a guide groove formed in the arm at a location spaced from the cam groove, the guide groove having a guiding opening at the outer peripheral edge of the arm and an extending to the bearing hole to guide the support shaft to the bearing hole when assembling the lever with the housing, the guide groove including a shortest guiding portion linearly connecting the guiding opening and the bearing hole, the guide groove further including a wide portion that is wider than both an inner diameter of the bearing hole and an opening width of the guiding opening;
- and
- a retracted portion formed in the guide groove at a position spaced from the guiding opening and the bearing hole, the retracted portion being configured to allow the operating portion to be displaced away from the wire bundle when assembling the lever with the housing, wherein a part of the wide portion serves as the retracted portion.

- a housing having a support shaft formed on an outer side surface, a wire bundle being drawn out from a wire draw-out surface;
- a lever including an arm;
- an operating portion extending from an outer peripheral edge of the arm, the operating portion being configured to be displaced to approach the wire draw-out surface when assembling the lever with the housing;
- a bearing hole formed in the arm, the bearing hole being configured to rotatably support the lever with respect to the housing by being fit to the support shaft;
- a guide groove formed in the arm, the guide groove being configured to guide the support shaft to the bearing hole when assembling the lever with the housing;
- and
- a retracted portion formed in the guide groove, the retracted portion being configured to allow the operating portion to be displaced away from the wire bundle when assembling the lever with the housing, wherein:
- the lever is rotatable between an initial position where the lever waits at the start of connection to a mating connector and a connection position where the connection to the mating connector is completed;
- a reverse rotation restricting projection projecting from an area corresponding to the guide groove is formed on a surface of the arm on a side opposite to the guide groove;
- and
- the housing is formed with a rotation restricting portion configured to restrict rotation of the lever at the initial position toward a side opposite to the connection position by being locked to the reverse rotation restricting projection.
