    • A board-mounted electrical connector makes it possible to sufficiently reduce stress in the connector housing caused by threaded attachment fixtures. Metal fixtures (30) for mounting of the electrical connector to a circuit board are arranged in end sections (27) of a thin and long housing (20). The metal fixtures (30) are secured in oblong openings (72) provided in end portions (46) of a metal shield (40) attached to an outside surface of the housing (20) so that they cannot rotate inside the openings. The metal fixtures (30) are retained in the openings by means of integral resilient retaining members (71) of the shield (40) being disposed in grooves (36) in the metal fixtures (30).
    • 板安装的电连接器使得可以充分减少由螺纹附接固定件引起的连接器壳体中的应力。 用于将电连接器安装到电路板的金属固定件(30)布置在薄且长的壳体(20)的端部(27)中。 金属固定件(30)固定在设置在附接到壳体(20)的外表面的金属屏蔽件(40)的端部(46)中的长圆形开口(72)中,使得它们不能在开口内旋转。 通过设置在金属夹具(30)中的凹槽(36)中的金属固定件(30)通过屏蔽件(40)的整体弹性保持构件(71)保持在开口中。
