    摘要： A fastener apparatus for mechanically connecting and holding the main housing of an electrical device, such as an electrical connector, to a substrate, such as a PCB, in a manner that allows for a relatively low insertion force and a corresponding relatively high retention force. The fasteners are adapted for attachment to both an electrical connector and to a substrate, thereby forming a mechanical connection between the two. Preferably, one or more fasteners are attached to the housing of the electrical connector and then the electrical connector having fasteners extending therefrom is connected to board openings formed in the PCB. The fastener apparatus is constructed having one or more arms connected to a bottom end of the fastener, the arms sweep outward and upward from the bottom end toward the top end. Preferably, the arms have a cantilevered design that allows the arms to deflect inward during insertion of the fastener into the board openings, thereby providing for a relatively low insertion force. Preferably, the arms are also formed having a taper. The tapered design of the arms has a predetermined inclined surface, forming an angle of inclination which results in a more onsistent insertion force, and does not create any sudden release of force or energy during insertion of the fastener into the substrate which might dislodge components mounted on the surface of the substrate. The arms are formed having an apex formed at the distal end. The apexes are adapted for connectively engaging the side walls of the board openings of the substrate thereby providing a retention force to hold the connector on the substrate. In addition, the arms tend to splay outward when a withdrawal force is applied to the fastener causing the arms to bite into the side walls of the board opening. This results relatively high retention force that holds the connector on the substrate.

    摘要翻译： 一种用于以允许相对低的插入力和相应的较高保持力的方式机械地将诸如电连接器的电气装置的主壳体机械地连接和保持到诸如PCB的基板的紧固装置。 紧固件适于附接到电连接器和基板，从而在两者之间形成机械连接。 优选地，一个或多个紧固件连接到电连接器的壳体，然后具有从其延伸的紧固件的电连接器连接到形成在PCB中的板开口。 紧固件装置被构造成具有连接到紧固件的底端的一个或多个臂，臂从底端朝向顶端向外和向上扫掠。 优选地，臂具有悬臂设计，其允许臂在将紧固件插入板开口期间向内偏转，从而提供相对低的插入力。 优选地，臂也形成为具有锥形。 臂的锥形设计具有预定的倾斜表面，形成倾斜角度，这导致更一致的插入力，并且在将紧固件插入衬底期间不会产生任何突然释放的力或能量，这可能会使安装的部件移动 在基板的表面上。 臂形成有在顶端形成的顶点。 顶点适于连接地接合基板的板开口的侧壁，从而提供保持力以将连接器保持在基板上。 此外，当拉紧力施加到紧固件上时，臂倾向于向外张开，导致臂咬入板开口的侧壁。 这导致将连接器保持在基板上的相对较高的保持力。
