    • A unitary mounting carrier structure supports a display panel and acoustic transducer components within a housing sub-portion of a telephone test set containing a keypad, an earpiece receiver port, a display panel face, and an auxiliary speaker port at an end portion of the test set. The unitary carrier structure is generally wedge-configured and has a generally flat, liquid crystal display panel unit-mounting section upon which a shock-absorbing gasket assembly containing a display panel unit is mounted. An earpiece receiver-mounting section is contiguous with a wider end of the carrier, and is contiguous with the generally flat, display panel unit-mounting section. An auxiliary speaker-mounting section is supported by the carrier adjacent and transverse to the earpiece receiver-mounting section. A desiccant-retaining section is supported adjacent to the display panel unit-mounting section, and serves to reduce the dew point within the test set to a value in a range on the order of 0.degree.-65.degree. F., thereby preventing the display panel unit from `fogging-up`, as may otherwise occur when the test set is taken from an air-conditioned vehicle to a warm and humid outdoor environment.
    • 一体式安装支架结构支持显示面板和声学换能器部件,其在包含键盘,听筒接收器端口,显示面板面和在测试的端部的辅助扬声器端口的电话测试装置的壳体子部分内 组。 单一载体结构通常是楔形构造的并且具有大致平坦的液晶显示面板单元安装部分,其上安装有包含显示面板单元的减震垫圈组件。 听筒接收器安装部分与载体的较宽端相邻,并且与大体上平坦的显示面板单元安装部分邻接。 辅助扬声器安装部分由承载件支撑在邻近和横向于听筒接收器安装部分。 在显示面板单元安装部附近支撑干燥剂保持部,用于将试验台内的露点降低到0°-65°F的范围内的值,从而防止显示 面板单元从“起雾”开始,否则当将测试装置从空调车辆带到温暖和潮湿的室外环境时可能会发生。

    • A strain relief attachment for attaching a telephone communication cord to a telephone test set has a line cord strain relief element, a grooved neck end of which is insertable through a tunnel through an end of the test set to a strain relief engagement cavity adjacent to a battery compartment of the test set and accessible by a battery door. The strain relief element includes a bore through which the line cord extends and a flange configured to conform with an external surface of the test set adjacent to the tunnel. The strain relief element engagement cavity is connected by a line cord passageway to the battery compartment. A wedge-shaped line cord retention plug is inserted into the strain relief engagement cavity, engaging the grooved neck of the line cord strain relief element and a wall surface of the strain relief engagement cavity. As the wedge-shaped line cord retention plug is inserted into the cavity, it draws the line cord strain relief element into the test set, urging the flange of the line cord strain relief element into sealing engagement with the external surface of the test set.

    • Unwanted acoustic noise and environmental degradation associated with the use of a highly sensitive microphone in a telephone test set are eliminated by a microphone-integrated keypad laminate architecture, in which a microphone is snugly captured within a microphone holder molded into a pliable keypad unit and its leads sealed against the environment and case vibration. The keypad unit is supported by a keypad support structure adjacent to the test set's keypad face, so that the microphone holder is retained adjacent to an acoustic coupling port, and the keypad's keys are accessible by way of keypad apertures in the keypad face. A printed circuit board urges the keypad unit into engagement with the keypad support structure. The keypad unit and the printed circuit board have sealed aperture arrangements through which electrical leads of the microphone pass for connection to the circuit board.
    • 通过麦克风集成的键盘层叠结构消除了在电话测试装置中与使用高灵敏度麦克风相关联的不期望的声学噪声和环境退化,其中将麦克风紧密地捕获在模制成柔性键盘单元的麦克风支架内,并且其麦克风 引线密封,防止环境振动。 键盘单元由与测试仪的键盘面相邻的键盘支撑结构支持,使得麦克风保持器保持在声耦合端口附近,并且键盘的键可通过键盘面板中的键盘孔进行访问。 印刷电路板促使键盘单元与键盘支撑结构接合。 键盘单元和印刷电路板具有密封孔布置,麦克风的电引线通过该孔布置用于连接到电路板。
