    • An electrical system includes a solid state relay (1) and an electrical connector (2) that connects solid state relay (1) to a load (4). The solid state relay (1) includes a power MOSFET (Q1) for switching power to the load (4). A PNP transistor (Q2) monitors the voltage drop across the power MOSFET (Q1), and shuts the power MOSFET off when the voltage drop exceeds a reference level. The solid state relay circuitry floats when the power MOSFET is commanded OFF so there is no leakage to ground. The relay (1) can be used with an electrical connector that includes a short pin (34) or shunt (16) that is disconnected before male and female terminals (12, 22) are unmated. Disconnection of the shunt (16) or the short pin (34) causes the power MOSFET to be commanded OFF so that there is no current flowing through the male and female terminals (12, 22) when they reach an arc susceptible position. The solid state relay (1) and the connector (2) are suitable for use in a 42 Volt automotive electrical system.
    • 电气系统包括固态继电器(1)和将固态继电器(1)连接到负载(4)的电连接器(2)。 固态继电器(1)包括用于将功率切换到负载(4)的功率MOSFET(Q1)。 PNP晶体管(Q 2)监视功率MOSFET(Q1)两端的电压降,当电压降超过参考电平时,关闭功率MOSFET。 当功率MOSFET被关闭时,固态继电器电路漂移,因此没有泄漏到地。 继电器(1)可以与电连接器一起使用,该电连接器包括短插销(34)或分流器(16),在公母端子(12,22)未断开之前断开。 分流器(16)或短引脚(34)的断开导致功率MOSFET被关闭,使得当它们到达电弧敏感位置时,没有电流流过阳和阴端子(12,22)。 固态继电器(1)和连接器(2)适用于42伏汽车电气系统。

    • The present invention relates to a card-type terminal such as a PC card with a memory card such as a USIM card. It allows a memory card to be secured easily on a tray and inserted easily into a card-type terminal. A card-type terminal includes a tray slidable in and out freely with a memory card mounted, and a guide which helps the tray slide in and houses the inserted tray; in which the memory card is placed on the tray, which is slid into the guide, thereby installing the memory card in the card-type terminal. The tray has a holder which secures, to the tray, the forward-end center section of the memory card mounted along the insertion direction of the tray and an elastic restraining piece which secures, to the tray, the backward-end center section of the memory card mounted along the insertion direction of the tray.
    • 本发明涉及诸如具有诸如USIM卡的存储卡的PC卡的卡型终端。 它允许将存储卡容易地固定在托盘上并且容易地插入到卡型终端中。 卡式终端包括可自由滑动地安装有存储卡的托盘和帮助托盘滑入并容纳插入的托盘的引导件; 其中存储卡被放置在滑入引导件的托盘上,从而将存储卡安装在卡式终端中。 托盘具有保持器,其将沿着托盘的插入方向安装的存储卡的前端中心部分固定到托盘,弹性限制件将托盘固定到托盘的后端中心部分 存储卡沿托盘的插入方向安装。
