    Abstract: Liners are inserted into holes in printed circuit boards by means of a templet having holes therein at locations corresponding to the holes in the printed circuit board. An excess of liners are placed on top of the templet and the templet is vibrated until one liner enters each hole in the templet. Thereafter, the templet is placed on top of the printed circuit board and the individual liners are punched from the templet holes into the printed circuit board holes.

    Abstract: A hole liner includes a metal body insertable into a hole in a printed circuit board for holding a component lead to be soldered to the board. An upper stop limits insertion, while a resilient latch near the lower end of the body engages the lower surface of the board to prevent withdrawal of the liner. The lower end of the body includes jaws for gripping a component lead inserted into the liner, and at least one of the jaws is connected to the resilient latch. The outer surfaces of the jaws are angled inwardly to aid insertion of the body into the hole, and upon insertion the jaws contract and the latch is resiliently forced inwardly. Upon full insertion the latch moves to its latching position in engagement with the undersurface of the board. The mouth or gap defined by the jaws is smaller than the component lead, so that when the lead is inserted the latch is further extended, thus firmly holding the liner in place on the board.

    Abstract translation: 孔衬套包括可插入印刷电路板中的孔中的金属体，用于保持要焊接到电路板的部件引线。 上限限制插入，而靠近主体下端的弹性闩锁与板的下表面接合以防止衬套的退出。 本体的下端包括用于夹持插入衬套中的部件引线的夹爪，并且至少一个钳口连接到弹性闩锁。 夹爪的外表面向内成角度，以有助于将主体插入孔中，并且在插入时，夹爪收缩并且闩锁弹性地向内压。 当完全插入时，闩锁移动到其与板的下表面接合的闩锁位置。 由钳口限定的口或间隙小于部件引线，因此当引线插入时，闩锁进一步延伸，从而将衬垫牢固地保持在板上的适当位置。
