Description

电连接器 技术领域
本发明涉及一种电连接器。 背景技术
串行连接 SCSI(Serial attached SCSI; SAS)是一种通信协议 (communication protocol), 其主要规范计算机储存装置 (例如： 硬盘或磁带机等)的数据存取。 SAS属一种点对点串行 协议 (point-to-point serial protocol), 其是用来取代在 1980年代中期所推出的 parallel SCSI 汇流排技术。 SAS 装置使用差分信号 (differential signals)来进行通信， 差分信号可降低 parallel SCSI在高速通信传输下所遭遇的电容效应、 电感效应和噪声等不良影响， 从而达 成禾急定且高速串行通信 (serial communication)。
SAS继承标准 SCSI指令集 (standard SCSI command set)及光纤通道协议 (Fibre Channel protocol)的帧格式 (frame formats)和全双工通信 (foil-duplex communication)。每个 SAS装置 包含至少一收发机制 (transceiver mechanism), 收发机制包含发射器 (transmitter)和接收器 (receiver^ 可用两对导线分别连接两装置的连接插口内的发射器与对应的接收器。 在全双 工通信模式下， 各收发机制可同时通过两对导线传送与接收数据。
两装置的连接插口可使用连接线与连接器相连接，其中两对导线分别连接连接器上的 两对端子。 第一代 SAS的物理链路速率 (physical link rate)为 3.0Gbps(Gbit/s)， 目前使用的 主流为第二代 SAS， 其物理链路速率为第一代 SAS的两倍， 达 6.0Gbps。 在不久的将来会 推出第三代 SAS， 第三代 SAS的物理链路速率会进一步将第二代 SAS的物理链路速率提 高一倍， 达 12Gbps。 由于第三代 SAS连接器与第二代 SAS连接器的端子接脚的排列设计 相同， 因此当物理链路速率提高至 12Gbps 时， 使用现有连接器会发生电磁千扰 (EMI emision)及其两对端子间会产生串音干扰 (cross talk)等问题。 发明内容
鉴于前述问题， 一种新的电连接器被提出。
本发明一实施例的电连接器包含一绝缘本体及一第一组端子。第一组端子包含一第一 对差分信号端子、 一第二对差分信号端子、 一第一接地端子、 一第二接地端子， 以及一第 三接地端子。第一对差分信号端子可固定在绝缘本体。第一对差分信号端子可包含一第一 信号端子与一第二信号端子。第一信号端子与第二信号端子可分别包含一接脚。 第二对差 分信号端子可固定在绝缘本体。第二对差分信号端子可包含一第三信号端子与一第四信号 端子。 第三信号端子与第四信号端子可分别包含一接脚， 其中第一信号端子、 第二信号端 子、第三信号端子和第四信号端子是依序在一第一方向排列， 其中第一对差分信号端子的 所述接脚在横向于该第一方向的一第二方向上错开。第二对差分信号端子的所述接脚在横 向于该第二方向上错开。第一接地端子可邻设第一信号端子。第一接地端子可包含至少一 接脚， 其中第一接地端子的至少一接脚可靠近第一信号端子的接脚。 第二接地端子设置于 第二信号端子与第三信号端子之间。第二接地端子包含一第一接脚和一第二接脚。 第一接 脚靠近第三信号端子的接脚， 而第二接脚靠近第二信号端子的接脚。第三接地端子邻设于 第四信号端子。 第三接地端子包含至少一接脚， 其中第三接地端子的至少一接脚靠近第四 信号端子的接脚。
由于第一接地端子的接脚靠近第一信号端子的接脚、第二接地端子的一接脚靠近第二 信号端子的接脚及第二接地端子的另一接脚靠近第三信号端子的另一接脚和第三接地端 子的接脚靠近第四信号端子的接脚， 因此可降低电磁辐射。 附图说明

虽然图 1至图 6实施例揭示有另两组端子 (27和 28)，但本发明不限于具有三组端子 (20、 27和 28)的实施例。 本发明可运用在具有至少包含一第一组端子 20的电连接器上， 该第 一组端子 20包括上述的第一对差分信号端子 22、第二对差分信号端子 23、第一接地端子 24、 第二接地端子 25及第三接地端子 26。

如图 7所示， 在一实施例中， 第一对差分信号端子 22的两接脚 221是介于第一接地 端子 24的接脚 241a和第二接地端子 25的第二接脚 251b之间，而第二对差分信号端子 23 的两接脚 231是介于第二接地端子 25的第一接脚 251a和第三接地端子 26的接脚 261a之 间。 在一实施例中， 第一接地端子 24的接脚 241a、 第一对差分信号端子 22的两接脚 221 和第二接地端子 25的第二接脚 251b沿一对角线方向 5排成一列， 而第二接地端子 25的 第一接脚 251a、 第二对差分信号端子 23的两接脚 231和第三接地端子 26的接脚 261b沿 一对角线方向 5排成一列。 如此的设计， 会有较佳信号传输效果。
参照图 6所示， 在一实施例中， 第一接地端子 24可包含一板状主体 242且具有两接 脚 (241a和 241b)，其中两接脚 (241a和 241b)从板状主体 242延伸。通过两接脚 241a和 241b 同时接地， 可降低第一接地端子 24的等效电感， 从而进一步降低第一对差分信号端子 22 所产生的电磁干扰。在一实施例中， 板状主体 242在第二方向 4上的尺寸较第一对差分信 号端子 22与第二对差分信号端子 23在第二方向 4上的尺寸为大。在另一实施例中， 第一 接地端子 24不具有板状主体。
在一实施例中，第三接地端子 26可包含一板状主体 262且具有两接脚 (261a和 261b)， 其中两接脚 (261a和 261b)从板状主体 262延伸。通过两接脚 261a和 261b同时接地， 可降 低第三接地端子 26的等效电感，从而进一步降低第二对差分信号端子 23所产生的电磁干 扰。 在一实施例中， 板状主体 262在第二方向 4上的尺寸较第一对差分信号端子 22与第 二对差分信号端子 23在第二方向 4上的尺寸为大。在另一实施例中，.第三接地端子 26不 具有板状主体。

在本发明的一实施例中， 电连接器包含一第一接地端子、 一第一对差分信号端子、一 第二接地端子、一第二对差分信号端子及一第三接地端子， 其中第一对差分信号端子设置 于第一接地端子与第二接地端子之间，而第二对差分信号端子设置于第二接地端子与第三 接地端子之间。第一对差分信号端子包含一第一信号端子及一第二信号端子， 其中第一信 号端子靠近第一接地端子， 而第二信号端子靠近第二接地端子。第二对差分信号端子包含 一第三信号端子及一第四信号端子， 其中第三信号端子靠近第二接地端子， 而第四信号端 子靠近第三接地端子。第一接地端子具有一接脚， 且第一接地端子的接脚靠近第一信号端 子的接脚。第二接地端子具有两接脚， 其中第二接地端子的一接脚靠近第二信号端子的接 脚， 而第二接地端子的另一接脚靠近第三信号端子的接脚。 第三接地端子具有一接脚， 且 第三端子的接脚接近第四信号端子的该接脚。由于每一对差分信号端子的每一接脚都靠近 其相邻的接地端子的接脚， 因此可降低每一对差分信号端子所产生的电磁干扰。 再者， 第 二接地端子包含一板状主体，板状主体可降低第一对差分信号端子与第二对差分信号端子 间的串音干扰。 此外， 第一接地端子与第三接地端子¾1分别具有两接脚， 如此可降低第一 接地端子与第三接地端子的等效电感，从而进一步降低每一对差分信号端子所产生的电磁 干扰。
本揭露的技术内容及技术特点已揭示如上，然而本领域技术人员仍可能基于本揭露的 教示及揭示而作种种不背离本揭露精神的替换及修饰。 因此， 本揭露的保护范围应不限于 实施范例所揭示的， 而应包括各种不背离本揭露的替换及修饰， 并为所附的权利要求书所 涵盖。
