    • A slide actuated holding clamp for holding a connector block stationary while a push test is performed on a conductor secured to the connector. The clamp comprises a body portion having a bore extending longitudinally therethrough and a portion forming a channel. A locking member is pivotally disposed within the channel and includes a locking finger portion and a lower shoulder portion. An actuating member is slidably disposed within the channel and includes a pin member extending transversely therethrough which causes the locking member to move pivotally such that the locking finger portion is moved outwardly of the channel when the actuating member is moved in a first direction. When the actuating member is moved in a longitudinally opposite second direction, the pin member abuttingly engages the lower shoulder portion, thereby causing the locking member to move pivotally such that the locking finger portion is retracted to a position within the channel. A small, conventional air cylinder is coupled to the actuating member via a linkage rod and a clevis to urge the actuating member slidably in the first and second directions in response to the application of air pressure thereto. The clamp will hold a connector stationary while large push forces are exerted on conductors coupled to the connector with only a very small force applied by the air cylinder. The design of the clamp does not require the air cylinder to exert a counter force in proportion to the push force being exerted on the connector.
    • 一个用于在对固定在连接器上的导体进行推测试的情况下固定连接器块的滑动致动夹持夹。 夹具包括具有纵向穿过其中延伸的孔的主体部分和形成通道的部分。 锁定构件枢转地设置在通道内,并且包括锁定指状部分和下部肩部部分。 致动构件可滑动地设置在通道内,并且包括横向穿过其中延伸的销构件,其使得锁定构件枢转地移动,使得当致动构件沿第一方向移动时,锁定指状部分在通道外移动。 当致动构件沿纵向相反的第二方向移动时,销构件与下肩部部分邻接地接合,从而使得锁定构件枢转地移动,使得锁定指状部分缩回到通道内的位置。 小型常规气缸经由连杆和U形夹连接到致动构件,以响应于向其施加空气压力而在第一和第二方向上可滑动地致动致动构件。 夹具将固定连接器固定,而大的推力施加在连接到连接器的导体上,只有非常小的力被气缸施加。 夹具的设计不需要气缸与施加在连接器上的推力成比例地施加反作用力。

    • A slide actuated holding clamp for holding a connector stationary while a push test or pull test is performed on a conductor secured to the connector. The clamp comprises a main body portion having an opening formed therein, a locking member adapted to fit nestably substantially within the opening, and an actuating member adapted to fit nestably within a recessed portion in the locking member. The actuating member is pivotally coupled to an upper end portion of the locking member and the locking member is captively held within the opening in the main body portion by a locking pin. The locking member includes elongated openings which allow the locking member to be urged slidably longitudinally within the main body portion as the actuating member is moved in first and second longitudinal directions. The pivotal coupling of the actuating member and locking member allows the locking member to be urged pivotally into abutting engagement with a connector as the actuating member is moved in a first linear direction. The elongated apertures permit the actuating member to urge the locking member generally linearly in the same direction as the actuating member as the actuating member continues to be moved in the first direction. This causes the locking member to exert a positive clamping force on the connector prior to conducting a push test or pull test.
    • 用于在对固定到连接器的导体进行推测试或拉力测试时将滑动驱动的夹持夹持器固定住连接器。 夹具包括具有形成在其中的开口的主体部分,适于基本嵌合在开口内的锁定构件,以及适于嵌合地配合在锁定构件中的凹部内的致动构件。 致动构件枢转地联接到锁定构件的上端部分,并且锁定构件通过锁定销牢固地保持在主体部分的开口内。 锁定构件包括细长开口,其允许当致动构件在第一和第二纵向方向上移动时锁定构件在主体部分内可滑动地纵向地推压。 致动构件和锁定构件的枢转联接允许当致动构件在第一线性方向上移动时,锁定构件被枢转地枢转地与连接器邻接接合。 细长的孔允许致动构件在致动构件继续沿第一方向移动时沿着与致动构件相同的方向大致直线地推动锁定构件。 这将导致锁定构件在进行推压测试或拉力测试之前在连接器上施加正的夹紧力。
