    • A self-latching jaw assembly is illustrated which includes a pair of latching jaws (A) and (B) for latching a fitting of an associated structure such as the keel fitting (50) of a space telescope. The jaw assembly automatically locates the fitting received on a positioning pedestal (52) and latches it in its original location on the pedestal without need of precision alignment. The first jaw (A) is actuated and moved to the right whereupon a reciprocating plunger (62) will have been extended from the nose (64) of the jaw and will sense the hub (50b) of the spool (50a). A jaw position responsive switch (72) is then actuated to terminate the drive motor (E) of the jaw (A). The astronaut will then actuate the drive motor (F) of the jaw (B) and the jaw will move to the left whereupon standoff (82) will engage the face (64a) of the jaw (A) in a latching position. In the latching position, the noses (64) and (83) of the jaws (A) and (B) will be under the flanges of the spool (50a).
    • 示出了一种自锁式夹爪组件,其包括一对闭锁爪(A)和(B),用于锁定诸如空间望远镜的龙骨配件(50)的相关结构的配件。 钳口组件自动将接收的配件定位在定位基座(52)上,并将其锁定在基座上的原始位置,而不需要精确对准。 第一钳口(A)被致动并向右运动,随后往复运动的柱塞(62)将从钳口的鼻部(64)延伸并且将感测线轴(50a)的轮毂(50b)。 然后致动钳位置响应开关(72)以终止钳口(A)的驱动马达(E)。 然后,宇航员将启动钳口(B)的驱动马达(F),并且卡爪将向左移动,随后支座(82)将在闩锁位置与卡爪(A)的表面(64a)啮合。 在锁定位置,夹爪(A)和(B)的鼻部(64)和(83)将在线轴(50a)的凸缘下方。
