    • A connector receptacle is provided with one flat external side for application to a printed circuit board. The connector receptacle has enclosing guiding walls terminating in a latch element. At least a pair of conductive female connectors are provided within slots in the connector receptacle. Each of these pieces providing the connectors consists of a pair of aligned female conductors integral with a pin connector support interconnected through a bridge and is formed of a single piece of sheet metal. The bridge also extends between the aligned pair of female conductors and supports a transversely extending spring tab which is used to enter a transverse slot in the connector receptacle to hold the integral piece in place. The female connector pieces are reversible for use in the slots provided on opposite sides of the connector receptacle. The circuit breaker, having electric terminal connectors which cooperate with the female connectors of the receptacle, is modified to provide a latch element extending in the direction of the terminal connectors from the circuit breaker and cooperative with the latch element on the connector receptacle to engage and hold the circuit breaker in position with the terminal connectors engaged with the female connectors of the connector receptacle.
    • 连接器插座设置有一个平坦的外侧,用于印刷电路板。 连接器插座具有端接在闩锁元件中的封闭引导壁。 至少一对导电阴连接器设置在连接器插座中的槽内。 提供连接器的这些部件中的每一个由一对对齐的阴导体组成,该导体与通过桥互连的销连接器支架成一整体,并且由一片金属板形成。 该桥还在对准的一对母导体之间延伸并且支撑横向延伸的弹簧片,其用于进入连接器插座中的横向狭槽以将整体件保持在适当的位置。 阴连接器片是可逆的,用于设置在连接器插座的相对侧上的插槽。 具有与插座的母连接器配合的电气端子连接器的断路器被修改以提供从断路器沿端子连接器的方向延伸并且与连接器插座上的闩锁元件协作的闩锁元件, 将断路器固定就位,使端子连接器与连接器插座的母连接器接合。

    • A two pole breaker employs molded resinous parts including a base and support frame structure. Supported to a medial plane frame by a pin is a rocker handle having a linkage crank arm at each side of the medial plane and a rotatable latch lever having trip surfaces accessible to a bi-metallic overload actuator of each pole. A rocker member generally transverse to the normal position of the latch lever has a latch surface which cooperates with a latch keeper on the latch lever which is held engaged by a spring between the latch lever and the medial plane. The rocker has parallel side members, each supporting a switch actuator surface on each side of the medial plane frame. Identical linkage connections on each side of the medial plane connect the crank arms to the respective side pieces of the rocker. Overload causes a bi-metal actuator to move the latch lever in opposition to its spring to release the rocker to a position to which the guide slot directs it allowing the contacts to open and moving the handle and linkage pins to a position where they are moved back over center. The handle movement pulls the rocker back up into position to relatch with the latch lever, moving the latch lever out of the way against the action of the spring, if needed.
    • 双极断路器采用模制树脂部件,包括基座和支撑框架结构。 通过销支撑在中间平面框架上的是具有在中间平面的每一侧具有联动曲柄臂的摇杆手柄和具有可由每个极的双金属过载致动器接近的跳闸表面的可旋转闩锁杆。 大致横向于闩锁杆的正常位置的摇杆构件具有闩锁表面,该闩锁表面与闩锁杆上的闩锁保持器协作,闩锁杆由闩锁杆和中间平面之间的弹簧保持接合。 摇臂具有平行的侧面构件,每个支撑在中间平面框架的每一侧上支撑开关致动器表面。 内侧平面两侧的相同的连接连接将曲柄臂连接到摇臂的相应侧片上。 过载导致双金属致动器将闩锁杆与其弹簧相对移动,以将摇臂释放到引导槽引导的位置,允许触点打开并将手柄和连杆销移动到它们移动的位置 回到中心。 手柄运动将摇杆拉回到适当的位置,以与闩锁杆重合,如果需要,将闩锁杆移动抵抗弹簧的作用。
