    • An electrical connector includes a housing having a forward mating end and a rearward terminating end and at least one terminal-receiving cavity extending in a direction between the ends. A terminal is insertable into the cavity from the rearward terminating end of the housing. A TPA device is selectively engageable with the housing in two positions, preloaded and fully loaded, at the terminating end of the housing, with a terminal retention portion insertable into the cavity in locking engagement with the terminal. Complementary interengaging abutments are provided between the terminal and the TPA device for moving the terminal from at least one incomplete position of insertion to a fully inserted position in response to moving the TPA device from the preloaded position to the fully loaded position thereof. The TPA device is held on the housing in either of the preloaded position or the fully loaded position thereof in such a manner as to allow the TPA device to be readily removed from the housing along with the terminals therewith.
    • 电连接器包括具有前配合端和后端接终端的壳体以及沿端部之间的方向延伸的至少一个端子容纳腔。 端子可从壳体的后方终端插入空腔中。 在壳体的终端处,TPA装置可选择性地与壳体接合在两个位置,预加载和完全装载,其中端子保持部分可插入到空腔中,与端子锁定接合。 在端子和TPA装置之间提供互补的相互接合抵接件,用于响应于将TPA装置从预加载位置移动到其完全装载位置,将端子从插入的至少一个不完全位置移动到完全插入位置。 TPA装置以任何一个预加载位置或完全装载的位置被保持在壳体上,以便允许TPA装置与其端子一起容易地从壳体移除。
