摘要： An electrical connector for conducting high frequency signals includes a number of input and output terminals that are interconnected by a pair of metallic lead frames that are mounted on a dielectric spring block. The lead frames are identical to each other and comprise several flat elongated conductors, each conductor terminating in a spring contact at one end and an insulation-displacing connector at the other. The lead frames are mounted on top of each other and their conductors are all generally parallel and close to each other. Only three of the conductors of each lead frame are arranged to overlap each other; and this occurs in a designated crossover region without electrical contact being made because of a reentrant bend in the conductors in the crossover region. As a result, crosstalk between specific conductors can be reduced by judiciously choosing the location of the crossover and the particular crossover pattern.

摘要： A plug for interconnecting a pair of wires at its input with a pair of insulation displacement connectors (IDC) at its output is improved. The plug comprises a dielectric housing and a pair of non-insulated conductors within the housing that cross over and are spaced-apart from each other. Each conductor comprises a generally flat blade portion for insertion into an IDC at one end, and a terminal for making electrical contact with a wire at the other. In the illustrative embodiment of the invention, the terminal comprises an insulation displacement connector. Additionally, the conductors are identical to each other, but are reverse-mounted with respect to each other to achieve crossover.

摘要： A manually operated switch that combines spring and contact functions in a low profile, machine-insertable component. The switch readily mounts onto a printed wiring board. It includes a cantilevered leaf spring member having one free end and a pair of spaced-apart fulcrums at the other end; one of the fulcrums being at the point of attachment of the leaf spring to the printed wiring board and the other being a re-entrant bend in the leaf spring in the vicinity of its center. An actuator is positioned to apply a force between the fulcrums such that the free end moves in a direction opposite to the direction of the applied force. Each spring member in combination with suitably placed contact pads is capable of providing a separate switch operation such as: "make" operation, "break" operation, or make-before-break "transfer" operation. A single actuator operates one or more spring members, each independently providing a different one of the above-described switch operations.
摘要翻译：一种手动操作的开关，将弹簧和接触功能组合在一个低轮廓，机械可插入的部件中。开关容易安装在印刷电路板上。它包括在另一端具有一个自由端和一对间隔开的支点的悬臂板弹簧构件; 其中一个支点是在板簧连接到印刷线路板的位置，另一个是在其中心附近的板簧中的重入弯曲。定位致动器以在支点之间施加力，使得自由端沿与施加的力的方向相反的方向移动。每个弹簧构件与适当放置的接触垫组合能够提供单独的开关操作，例如：“使”操作，“断开”操作或进行“断开”“传送”操作。单个致动器操作一个或多个弹簧构件，每个弹簧构件独立地提供上述开关操作中的不同的一个。
