摘要： A modular jack includes a substantially rectangular dielectric receptacle housing having a front face, a bottom board mounting wall, and a top, rear and a pair of side walls substantially surrounding a plug-receiving cavity. The cavity extends rearwardly from the front face for receiving a mating plug connector. In order to limit insertion of an undersized plug into a full-sized plug-receiving cavity in the receptacle housing, a stop surface is incorporated into a flexible stop member projecting from the housing and extending into the plug-receiving cavity. The stop surface is located within the cavity so as to ensure contact with a leading edge of an undersized plug upon insertion of the undersized plug into the cavity. A sliding surface is also incorporated into the flexible member. The sliding surface is located within the cavity so as to ensure contact with a leading edge of a plug upon insertion into the cavity of a mating plug having a width appropriate for mating with the jack. The sliding surface resides closer to the front face of the receptacle housing than does the stop surface. When an undersized plug is inserted into the cavity, the leading edge of the undersized plug contacts the stop surface, preventing full insertion of the undersized plug into the cavity. When a mating plug is inserted into the cavity, the leading edge of the mating plug contacts the more forwardly-positioned sliding surface before reaching the stop surface. Sliding contact between the sliding surface and the mating plug leading edge causes the sliding surface to move. This movement produces a corresponding movement in the flexible stop member and the stop surface incorporated thereon such that the stop surface is located out of engagement with the leading surface of the mating plug, permitting full insertion of the mating plug into the cavity.
摘要翻译：模块插座包括具有前表面，底板安装壁以及基本上围绕插头接收腔的顶部，后部和一对侧壁的基本上矩形的电介质插座壳体。空腔从前表面向后延伸，用于接收匹配的插头连接器。为了限制将尺寸过小的插头插入到插座壳体中的全尺寸的插头接收腔中，止动表面被结合到从壳体突出并延伸到插头接收腔中的柔性止动构件中。止动表面位于空腔内，以便在将小尺寸的插头插入空腔中时确保与尺寸过小的塞子的前缘接触。滑动表面也结合到柔性构件中。滑动表面位于空腔内，以便在插入具有适于与千斤顶配合的宽度的配合插头的空腔中时确保与插头的前缘接触。滑动表面比止动表面更靠近插座壳体的前表面。当一个尺寸过小的插头插入空腔中时，尺寸过小的插头的前端会碰到止动表面，从而防止将过小的插头完全插入到空腔中。当匹配插头插入空腔时，匹配插头的前缘在到达止动表面之前接触更向前定位的滑动表面。滑动面与配合插头前缘之间的滑动接触导致滑动面移动。这种移动在柔性止动构件和其上结合的止动表面上产生相应的运动，使得止动表面定位成不与配合插塞的前表面接合，从而允许将配合插塞完全插入空腔中。
