技术领域
本发明涉及电子连接设备领域， 尤其涉及一种高速连接器插座以及插头。 背景技术
小型插接式（ SFP, Small Form-factor Pluggables ) 高速接口连接器广泛 应用于通信产品中， 是重要的业务接口。 SFP高速接口连接器可以应用于： 通 用公共无线（CPRI, Central Power and Research institute of INDIA )接口， 千 兆以太网 （GE, Gigabit Ethernet )接口和高速以太网 （FE, fast Ethernet )接 口等。 随着通信产品带宽的需求的不断增加， SFP连接器只能支持 1路高速信 号， 逐渐无法满足通信产品带宽发展的需求。

发明内容
本发明实施例提供了一种高速连接器插座以及插头，用于实现多路高速信 号的通信传输。
本发明的高速连接器插座， 包括： 壳体（10 )和引脚（20 ); 所述壳体（10 ) 具有开口， 所述的开口用以容纳高速连接器的插头； 所述引脚（20 )包括上层 引脚（201 )和下层引脚（202 ); 所述上层引脚（201 )设置在所述开口的内壁 的一侧，所述下层引脚（ 202 )设置在所述开口的内壁上与所述上层引脚（ 201 ) 所在位置相对应的另一侧， 所述下层引脚（202 )排布成至少两排的引脚组， 所述至少两排的引脚组沿引脚（ 20 )长度的方向错位分布；所述上层引脚（ 201 ) 与一排所述引脚组相对应。
本发明的高速连接器插头， 包括： 电路板（30 )和引脚端子（40 ); 所述 引脚端子（40 )包括第一引脚端子和第二引脚端子； 所述第一引脚端子设置在 所述电路板 ( 30 )的一面， 所述第二引脚端子设置在所述电路板（30 )的另一 面； 所述第二引脚端子排布成至少两排的引脚端子组， 所述至少两排的引脚端 子组沿引脚端子（40 )长度的方向错位分布； 所述第一引脚端子与一排所述引 脚端子组相对应。
从以上技术方案可以看出， 本发明实施例具有以下优点： 本发明高速连接 器插座的下层引脚排布成至少两排的引脚组，而且该至少两排的引脚组是沿引 脚长度方向错位分布的；这样的分布方式大大的缩小了高速连接器插座开口的 长度， 有效的利用插座的纵向空间， 使得高速连接器插座的整体体积减小， 有 利于高速连接器插座的安装和布置。

图 4是本发明实施例中高速连接器插头和插座的连接示意图。
具体实施方式
本发明实施例提供了一种高速连接器插座以及插头，用于实现多路高速信 号的通信传输。
本发明实施例中所描述的 "上下"、 "正反" 非严格的方位限定， 只是相对 的概念， 有助于分辨物体结构的相对位置关系。
请参阅图 1 , 本发明实施例中高速连接器插座的一个实施例包括： 本发明实施例中的开关连接器主要包含以下零部件：
壳体 10和引脚 20。
壳体 10具有容高速连接器插头插入的开口；
引脚 20包括： 上层引脚 201和下层引脚 202; 上层引脚 201—般用于传 输普通信号， 如： 接地信号、 发送故障信号、 连续数据信号、 连续始终信号和 频率选择信号等； 下层引脚 202用于传输高速信号， 如： 正射级耦合逻辑电平 ( PECL, Positive Emitter Coupled Logic )信号。
该上层引脚 201设置在该开口的内壁的一侧，该下层引脚 202设置在该开 口的内壁上与该上层引脚 201所在位置相对应的另一侧，该下层引脚 202排布 成至少两排的引脚组， 该至少两排的引脚组沿引脚 20长度的方向错位分布； 该上层引脚 201与其中一排引脚组的位置相对应。
上层引脚 201和下层引脚 202的触头为弹性件，该弹性件可以为弯曲的金 属簧片；上层引脚 201和下层引脚 202的尾端用熔接或压接的方式固定在凹槽 的底部。 引脚 20的触头用于连接高速连接器插头的引脚端子， 引脚 20的尾端 可以电性连接在终端的电路板上作为信号接口。
在工艺制造上，可以使用沖压机在壳体 10内塑造出多组放置引脚的凹槽， 每组 槽内有多个独立的 槽成排状整齐的分布，每个 槽的宽度与每个 I脚 20 的宽度相匹配， 引脚的尾端用熔接或压接的方式固定在凹槽的底部， 保证 了引脚 20在凹槽内的机械强度， 使得高速连接器的插座与插头相接时， 引脚 20的触头可以高精度的对应该插头的引脚端子。
此外， 为了使得高速连接器插头插入本发明的高速连接器插座后，插头和 插座的位置相对固定， 在本发明实施例中， 壳体 10开口的内壁中还可以带有 定位卡槽。
本发明高速连接器插座的下层引脚排布成至少两排的引脚组，而且该至少 两排的引脚组是沿引脚长度方向错位分布的；这样的分布方式大大的缩小了高 速连接器插座开口的长度，有效的利用了插座的纵向空间，使得高速连接器插 座的整体体积减小， 有利于高速连接器插座的安装和布置。
由于目前市场上的许多高速通信设备仍然使用 SFP插头， 要一次性的实 现多路高速连接器的更新换代还比较困难， 故本发明提供了可以使得 SFP插 头平滑升级的技术方案， 请参阅图 2, 本发明实施例中高速连接器插座的另一 个实施例包括：
壳体 10和引脚 20。
壳体 10具有容 SFP连接器插头插入的开口， 壳体 10开口的内壁下方镶 嵌着一个延伸托件 101 , 该延伸托件 101也分布有若干排凹槽， 该凹槽中可以 安置下层引脚 202。
引脚 20包括： 上层引脚 201和下层引脚 202, 壳体 10开口的内壁的一侧 设置有上层引脚 201 , 该开口的内壁的另一侧设置有下层引脚 202; 该下层引 脚 202排布成至少两排的引脚组， 该至少两排的引脚组沿引脚 20长度的方向 错位分布。 与上层引脚 201位置相对应的内壁的另一侧分布有一排引脚组， 该 引脚组分布在壳体 10开口的最内侧，其余的引脚组分布在该延伸托件 101上。
在实际应用中， 为了方便布线， 在本发明实施例的至少两排的引脚组中， 至少有一排引脚组中相邻的引脚之间的间距与相邻的另一排引脚组中相邻的 引脚之间的间距不同， 使得在沿引脚 20长度的方向上， 引脚的数据传输线的 布置可以相互错开， 充分利用空间。
由于目前市场上的一些设备仍沿用 SFP插头， 而 SFP插头的各引脚端子 之间的间距比较大， 因此， 本发明实施例中的高速连接器插座为了实现与 SFP 插头的兼容， 上层引脚 201、 与上层引脚 201位置相对应的下层引脚 202都和 SFP插头的引脚端子的分布方式一致。
本发明实施例中引脚 20的分布方式具体为： 上层引脚 201有 20个，相邻 两个上层引脚 201的间距为 0.8毫米； 同样， 与上层引脚 201位置相对应的一 排引脚组也是 20个下层引脚 202,相邻引脚之间的间距也为 0.8毫米； 其余的 各排引脚组每排有 36个下层引脚 202, 相邻引脚之间的间距为 0.65毫米。
分布方式一致包括： 引脚 20 (或引脚端子） 的数目一致， 引脚（或引脚 端子）之间的间距一致。 与 SFP插头的引脚端子对应上， 而且其余的下层引脚 202也可以使用较高密 度的排布方式， 在兼容 SFP插头的同时， 也可以尽可能多的传递数据信号。
在本发明实施例中，本发明的高速连接器插座可以插入现有技术中的 SEP 插头， 当 SEP插头插入本发明的高速连接器插座后， 由于该插座的引脚数和 SEP插头的引脚端子数目相同， 且引脚之间的间距与引脚端子之间的间距一 致， 所以插入后各个引脚端子与引脚相匹配， 可以实现电连接。
考虑到与现有技术中的 SEP插头尺寸匹配的问题， 防止本发明的高速连 接器插座由于下层引脚 202 过多， 导致该插座的壳体开口的深度较长， 导致 SEP插头插入后引脚端子无法接触到与其匹配的引脚 20, 所以本发明实施例 中， 除与上层引脚 201位置相对应的下层引脚 202外， 其余的下层引脚 202 全分布在延伸托件 101上， 该延伸托件 101与壳体 10开口的内壁下方用可装 卸式的形式契合在一起， 当延伸托件 101与壳体 10开口的内壁下方镶嵌时， 延伸托件 101上的各个下层引脚 202与高速连接器插座内的通信链路相连接； 当延伸托件 101与壳体 10分离时， 可以缩短壳体开口的深度， 使得 SEP插头 插入该壳体 10内时， 引脚端子可以与其相对于的引脚 20电连接。
本发明还提供了与上述高速连接器插座相匹配的高速连接器插头，请参阅 图 3 , 本发明实施例中高速连接器插头的一个实施例包括：
电路板 30和引脚端子 40;
引脚端子 40包括第一引脚端子和第二引脚端子；
第一引脚端子设置在该电路板 30的一面， 第二引脚端子设置在该电路板 30的另一面；
第二引脚端子排布成至少两排的引脚端子组，该至少两排的引脚端子组沿 是引脚端子 40长度的方向错位分布的； 且第一引脚端子与其中一排第二引脚 端子的位置相对应。
第一引脚端子与上述高速连接器插座实施例中的上层引脚 201 的分布方 式一致；
第二引脚端子与上述高速连接器插座实施例中的各排下层引脚 202 的分 布方式一致。
电路板 30内分布有信号传输电路， 该信号传输电路的输出端与引脚端子 40相连接， 该信号传输电路的输入端焊接或压接各种信号线（如： 接地信号、 发送故障信号、 连续数据信号、 连续始终信号、 频率选择信号和 PECL信号等 数据线）。
该电路板 30的厚度基本适配于上述实施例中壳体 10开口的宽度，该电路 板 30插入该壳体 10的开口后， 壳体 10开口内的引脚 20可以压在该电路板 30上， 保持一定的接触力。
此外， 为了使得高速连接器插头插入本发明的高速连接器插座后，插头和 插座的位置相对固定， 在本发明实施例中， 电路板 30的侧面上还可以带有定 位卡扣， 该定位卡扣与上述高速连接器插座实施例中的定位卡槽相适配。
在实际应用中， 为了方便布线， 在本发明实施例的至少两排引脚端子中， 子组中相邻的引脚端子之间的间距不同，使得在沿引脚端子 40长度的方向上， 引脚端子的数据传输线的布置可以相互错开， 充分利用空间。
在本实施例中， 为了匹配上述与现有技术中 SFP插头相兼容的高速连接 器插座， 本发明的高速连接器插头还可以包括以下特征：
第一引脚端子及其对应的第二引脚端子的分布方式与 SFP插头的引脚端 子的分布方式一致。 排布成一排， 相邻两个第一引脚端子之间的间距为 0.8毫米； 第二引脚端子沿 那一排引脚端子组中相邻引脚端子之间的间距也为 0.8毫米， 该排引脚端子组
0.65毫米， 每排引脚端子组有 36个第二引脚端子。
分布有该第二引脚端子的电路板 30的一面为至少两层的梯级结构， 该与 第一引脚端子相对应的那一排引脚端子组分布在该梯级结构中最底层的平面 上； 其余各排的引脚端子组分別分布在该梯级结构的其余各层平面上。这样的 设计可以使得电路板 30插入上述壳体 10的开口时， 避免不对应的引脚端子 40和引脚 20相接触引起的短路。
为了便于理解，下面以一本发明高速连接器插座与插头相连接的应用场景 进行描述， 请参考图 4, 具体为：
当本发明高速连接器插头插入本发明高速连接器插座内时（壳体 10开口 的容积应稍大于高速连接器插头的体积，使得高速连接器插头恰好插进该壳体 10内 ), 电路板 30侧面上的定位卡扣陷入壳体 10内壁中的定位卡槽， 该插头 和插座的位置相对固定。
此时， 壳体 10内部的引脚触头压接在高速连接器插头相应的引脚端子 40 上（上层引脚 201对应第一引脚端子， 各排下层引脚 202分別对应第二引脚端 子）， 使得引脚 20与相应的引脚端子有效的电连接； 其中， 该引脚触头的接触 面应该与该引脚端子的接触面的大小一致，使得本发明高速连接器的插座与插 头电连接时的阻抗匹配。
当各个引脚端子 40与引脚 20电连接后，高速连接器插头上各条的信号线 (包括多路高速信号） 与高速连接器插座的引脚 20相互导通， 可以有效地进 行多路高速信号的数据传输。
以上对本发明所提供的一种高速连接器插座以及插头进行了详细介绍，对 于本领域的一般技术人员，依据本发明实施例的思想，在具体实施方式及应用 范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
