    • An electrical protector device (10) for grounding excessive voltage and excessive current to safeguard telecommunications circuits includes a heat coil assembly (100) for sensing and directing excessive current to ground, and a spark gap arrester (200), axially aligned with the heat coil assembly (100), for sensing and controlling excessive voltage. Whenever an overcurrent condition is encountered, heat coil mechanism (110) is displaced to provide metallic contact of the incoming line to a ground structure (300). In addition, the device is adapted to provide protected testing of both incoming pairs and office equipment. Two test points (123) formed as part of the heat coil assembly (100) are in contact with the individual wires of the incoming line. These two test points are accessible through apertures (402) in the protector housing (400).

    • Portable test apparatus utilized to access a field of test points comprises either a single access tool (100) or a multiple access adaptor (200) depending on the mode of testing required. Tool (100) is usually employed for accessing the field to effect aperiodic testing whereas adaptor (200) is generally used for planned test activities.Tool (100) comprises body (111), guide assembly (150) and cover plater (170) which house clamp assembly (130) and pin contact assembly (180). Clamp assembly (130) operates in scissor-like fashion for engaging and disengaging tool (100) from test field grips (401). Spring-loaded pins (181) penetrate apertures (403) within the test field to contact the test points.Adaptor (200) comprises body (211), center panel (240) and guide (260) which enclose pin contact assembly (280); in addition, cam-lever drive assembly (210) attached to body (211). Drive assembly (210) has means for grasping a frame (50) associated with the test field so as to draw body (211) towards frame (50). In the engaged position, spring-loaded pins (281) contact the test point. Recesses (266) in the front face of guide (260) align juxtaposed test field grips to establish a uniform field of test points.Multiple slots in the drive assembly provide flexibility for test connector applications such as testing on the panel, outside plant or equipment and on protector families of different heights; however, all units in the panel must be the same height.
    • 用于访问测试点的便携式测试装置包括单个访问工具(100)或多个访问适配器(200),这取决于所需的测试模式。 工具(100)通常用于访问场以实现非周期性测试,而适配器(200)通常用于计划的测试活动。 工具(100)包括容纳夹具组件(130)和销接触组件(180)的主体(111),引导组件(150)和盖板(170)。 夹具组件130以类似剪刀的方式操作,用于使工具(100)与测试场夹具(401)接合和脱开。 弹簧加载销(181)穿过测试区域内的孔(403)以接触测试点。 适配器(200)包括主体(211),中心面板(240)和引导件(260),其包围销接触组件(280); 此外,附接到主体(211)的凸轮杆驱动组件(210)。 驱动组件(210)具有用于抓握与测试场相关联的框架(50)的装置,以便将主体(211)朝向框架(50)拉出。 在接合位置,弹簧加载销(281)接触测试点。 引导件(260)前表面上的凹槽(266)对准并置的测试场夹具,以建立测试点的均匀场。 驱动器组件中的多个插槽为测试连接器应用提供了灵活性,例如在面板,外部设备或设备以及不同高度的保护器系列上进行测试; 但是,面板中的所有单元必须具有相同的高度。
