Abstract
In an electrical connector locked and released by means of snap members, a supporting axle of the snap member is located between a sector-shaped bottom surface of the snap member and center of curvature of the sector so as to allow pivotal axis of the snap member to travel along elongated holes provided in the side walls as the snap member is pivoted and/or knurled edge and rib are provided at the top end of the snap member for guiding the female connector toward the male connector pins so as to align the pin holes of the female connector with the male connector pins.
Claims10
A structure of an electrical connector for coupling male and female connectors, comprising;
- (a) at least one connector pin of the male connector;
- (b) a frame member having a base portion through which said connector pin of the male connector extends and having at least one pair of side walls extending from said base portion;
- (c) at least one elongated snap member interposed between said pair of side walls for forcibly disengaging at least one connector pin receptacle of the female connector engaged with said connector pin of the male connector therefrom when an operator pivots said elongated snap member in a first direction so as to separate from said connector pin receptacle of the female connector and for locking said connector pin of the male connector in engagement with said connector pin receptacle of the female connector when the operator pivots in a second direction so as to approach to said connector pin receptacle of the female connector;
- and
- (d) at least one of the first means for producing a leverage action on a pivotal axis of said snap member to move in the direction of engagement and disengagement of said male and female connector pins with respect to said frame member when the operator pivots said snap member in the first and second directions so as to disengage and engage said connector pin receptacle of the female connector from and with said connector pin of the male connector, said first means including a base surface of said snap member in the shape of an arc and opposing a contact surface of said frame member, a finger projecting from the base surface in the direction to disengage said connector pin receptacle of the female connector from said connector pin of the male connector, a pivot pin projecting from said snap member toward both side walls of the frame member at a point between and spaced from both said base surface and a center of curvature of said base surface forming said arc, and means defining opposing holes penetrating said side walls for receiving said pivot pin of said snap member and elongated for allowing for movement of said pivot pin along said elongated opposing holes when the operator pivots said snap member in the first and second directions and second means formed on a surface of said snap member exposed to contact with said connector pin receptacle of the female connector and to engage a finger of the operator to outwardly pull said surface, said second means defining a predominantly rough finger engaging surface including a smooth projection which is located and shaped to prevent mutual contact which would otherwise take place between said rough surface and said connector pin receptacle of the female connector and which is inclined so as to guide said connector pin receptacle toward said connector pin of the male connector.
An electrical connector including a male connector having a plurality of pins and a horizontal elongated frame member through an intermediate portion of which said pins extend and from each end of which a pair of parallel side walls extend in a first direction perpendicular to the elongated frame and a female connector having a plurality of pin receptacles for receiving said pins of the male connector when the male and female connectors are engaged and a horizontally elongated frame member through which said pin receptacles are arranged, said electrical connector comprising means defining a pair of holes through said side walls, the holes being elongated in said first direction, a lever member interposed between said side walls and having a base surface shaped as a circular arc with a predetermined radius of curvature, said base surface of said lever member being in sliding and rolling contact with the end portion of said horizontally elongated frame member, a pivot pin disposed between said base surface and the center of the curvature thereof and extending through said pair of elongated holes so as to be guidably moved within said pair of elongated holes parallel to said first direction, in such a way that said pivot pin is moved first downwardly and then upwardly along the elongated holes as the lever member is pivoted to move the female connector upwardly and out of engagement with the male connector, and a finger projecting substantially in said first direction from said base surface into contact with said female connector when the male and female connectors are engaged, said finger driving said female connector out of engagement with said male connector when said lever is pivoted in one rotary direction.
