Abstract

A lever-actuated connector assembly includes first and second connectors and a generally U-shaped lever rotatably mounted on the first connector. The first connector is of one piece box-like construction and has an opening defined therein. The first connector has a pair of interior side walls opposite to each other, two pins extending outwardly from the respective interior side walls, two protective rear walls extending outwardly from the respective interior side walls, and two protective exterior side walls extending from exterior edges of the respective rear walls in a direction generally perpendicular to the direction in which the rear walls extend. The second connector has a pair of side walls opposite to each other and two pins integrally formed therewith so as to protrude outwardly therefrom. The lever has a pair of spaced arms and two bearing holes defined therein to receive the bearing pins of the first connector for angular movement between engaged and disengaged positions about a common axis of the bearing pins. When the lever is operated to join the first and second connectors together, the arms of the lever are inserted into associated gaps defined between the interior side walls and the exterior side walls of the first connector, thereby preventing an accidental removal of the arms of the lever from the first connector.

Claims3

Dependent claims

A lever-actuated connector assembly comprising:

a first connector having an opening defined therein and also having a pair of first side walls opposite to each other and on respective sides of said opening, said first side walls having respective bearing pins formed integrally therewith so as to protrude outwardly therefrom;
a second connector having a pair of second side walls opposite to each other, said second connector being undersized relative to said first connector thereby to permit said second connector to be selectively received in and removed out from said first connector through said opening in said first connector, said second side walls having respective guide pins integrally formed therewith so as to protrude outwardly therefrom;
a generally U-shaped lever having a pair of spaced arms having respective bearing holes defined therein, and each said bearing hole having a center, each of said spaced arms having a first edge and a second edge, the distance from said first edge to said center being greater than the distance from said second edge to said center, said lever being rotatably mounted on said first connector with said bearing pins engaged in said bearing holes for angular movement between engaged and disengaged positions about a common axis of said bearing pins;
and
protective wall means on said first connector, said protective wall means being spaced from said first side walls to form associated gaps therebetween, said protective wall means preventing outward disengagement of said arms from said bearing pins during a rotation of said lever between the engaged and disengaged positions, and whereby the arms of said lever are spaced outside of said gaps when said lever is in the disengaged position.

A lever-actuated connector assembly comprising:

a first connector having an opening defined therein and also having an interior bottom wall, a pair of interior side walls extending upwardly from respective side edges of said interior bottom wall, two bearing pins extending outwardly from said respective interior side walls, said bearing pins having a common axis, two protective rear walls extending outwardly from said respective interior side walls, and two protective exterior side walls extending from exterior edges of said respective rear walls in a direction generally perpendicular to the direction in which said rear walls extend;
a second connector having a pair of side walls opposite to each other, said second connector being undersized relative to said first connector thereby to permit said second connector to be selectively received in and removed out from said first connector through said opening in said first connector, said side walls having respective guide pins integrally formed therewith so as to protrude outwardly therefrom;
and
a generally U-shaped lever having a pair of spaced arms having respective bearing holes defined therein, each of said spaced arms having a first edge and a second edge, the distance between said first edge and said common axis being greater than the distance from said second edge to said common axis, said lever being rotatably mounted on said first connector with said bearing pins engaged in said bearing holes for angular movement between engaged and disengaged positions about said common axis of said bearing pins,
whereby, when said lever is operated to join said first and second connectors together in said engaged position, said arms of said lever, including said first edge, are rotated into associated gaps defined between said interior side walls and said exterior side walls of said first connector, thereby preventing an accidental removal of said arms of said lever from said first connector, and when said lever is in said disengaged position, said arms of said lever, including said first and second edges, are located outside of said associated gaps.
