    • Display element for an electromagnetic display device comprising a frame and a disc mounted to the frame for pivoting of the disc about a pivoting axis, the disc having two differently colored sides, an ON-side the color of which contrasts against the background color of the frame and an OFF-side having a non-contrasting color. An electromagnetic drive system drives the disc from a first operating position where its ON-side is directed towards the main viewing direction to a second operating position where its OFF-side is directed towards the viewing direction. The drive system comprises a permanent magnet attached to the disc and an electromagnet attached to the frame. A reliable operation with a reduced production cost is achieved by a combination of features, wherein two portions of the disc extend in a disc plane on both sides of the pivoting axis, the permanent magnet is attached to the disc and extends across the pivoting axis, the turning angle of the disc is less than 180°, the magnetic drive system has a single electromagnet and a driving tip of its ferromagnetic core is located sidewise of the pivoting axis such that in each of the operating positions one of the poles of the permanent magnet is directed towards the driving tip and the driving tip is in one of the operating positions rearward and in the other of the operating positions forward relative to the disc plane.
    • 一种用于电磁显示装置的显示元件,包括一个安装在框架上的框架和一个盘,用于围绕枢转轴线转动盘,该盘具有两个不同颜色的两侧,其一侧的颜色与 框架和具有非对比色的OFF侧。 电磁驱动系统从其第一操作位置驱动盘,其第一操作位置,其ON侧指向主观察方向到其OFF侧朝向观察方向的第二操作位置。 驱动系统包括附接到盘的永磁体和附接到框架的电磁体。 通过组合的特征来实现降低生产成本的可靠操作,其中盘的两个部分在枢转轴线的两侧的盘平面中延伸,永磁体附接到盘并且横越枢转轴线延伸, 磁盘的旋转角度小于180°,磁驱动系统具有单个电磁体,并且其铁磁芯的驱动尖端位于枢转轴线的侧面,使得在每个操作位置中,永磁体的一个极点 磁体指向驱动尖端,并且驱动尖端处于相对于盘平面向前的操作位置中的一个操作位置和另一个操作位置。

    • A connector fixing device and a connector including the fixing device are disclosed. The fixing device is formed by stamping a metal plate to have a base, a pair of fixing legs extending downward from the base for engaging with a mother board, and two fitting wings extending upward from two sides of the base and cooperating therewith to define a middle depression in an upper part of the fixing device. The two fitting wings interferentially fit into two grooves defined by two projection portions of a housing of the connector. The two projection portions are located at a bottom part of the housing beside a space defined by the housing which receives a foot portion of a card ejector. The card ejector is pivotably connected to the housing for ejecting an inserted electrical card. The middle depression of the fixing device is defined below the space receiving the foot portion of the card ejector.
    • 公开了一种连接器固定装置和包括固定装置的连接器。 固定装置通过冲压金属板以形成基座,从基座向下延伸以与母板接合的一对固定腿,以及从基座的两侧向上延伸并与之配合的两个安装翼, 固定装置上部的中间凹陷。 两个配合翼片沿周向配合到由连接器的壳体的两个突出部分限定的两个槽中。 两个突出部分位于壳体的底部旁边,由容纳卡排出器的脚部的壳体限定的空间。 卡片推出器可枢转地连接到壳体以弹出插入的电卡。 固定装置的中间凹陷被限定在接收卡片喷射器的脚部的空间的下方。
