技术领域
一般地说，本发明涉及电气连接器，更具体地说，涉及适用于具有变化电源要求的便携电子设备的电气连接器，这些便携电子设备包括膝上计算机、PDA、移动电话、MP3播放器、数字相机、以及便携DVD播放器。
背景技术
在消费者电子市场中，有各类便携电子设备，从蜂窝电话到个人数字助理(PDA)，到智能电话，到数字相机，到便携DVD播放器。每种设备对其内部电池有其特定电源要求，或由外部电源供电和/或对这个电池充电，如由AC壁上插座或DC电源。
现在在市场上可得到通用电源转换器，包括由Scottsdale Arizona的Mobility Electronics Inc.(本发明的申请者)提供的那些。提供了可互换的设备末端(tip)，这些末端与不同的便携电子设备兼容，而且适应于从通用电源转换器接收供电。
由于对每种设备的电源需求有很大变化，希望在通用电源市场中有一种方法将电源需求分类成一系列电源。每种电源能服务于目标电子设备的特定电源范围。
发明内容
本发明作为电气连接器、连接器组和连接器系统实现了若干技术上的好处。使设备连接器向后兼容于电源连接器，使得设备连接器只能与定额在电源连接器额定功率或在此之上的电源连接器耦合。例如，额定功率35瓦的设备连接器只能与定额在35瓦或在此之上的电源连接器耦合。类似地，一个15瓦的设备连接器只能与定额在15瓦或在此之上的电源连接器耦合，被供电的便携电子设备被防止在超过电源连接器和相关电缆额定功率的情况下抽取电力。
在一个优选实施例中，提供了一组设备连接器，它们具有终接于设备连接器接口的导体，这一接口有一个外围轮廓体部分，该部分的外形是设备连接器额定功率的函数。一个与之配对的电源连接器可包括一个电缆向其供电，该电源连接器有一个接口也具有外围轮廓体部分，它的外形是电源连接器额定功率的函数。有利的是，这些连接器的外围轮廓体部分被配置成只有当设备连接器的额定功率满足或超过电源连接器的额定功率时才能彼此配对。优选地，外围轮廓体部分被配置成插头和插座结构，有预定额定功率的每个插座只能接受具有相容额定功率的插头。
有利地，能为特定的功率范围开发电源，其中设备连接器与目标便携电子设备配对并与满足或超过这些目标便携电子设备额定功率的电源连接器及电缆配对。

具体实施方式
现在参考图1，图中总体显示一个键锁的连接器系统10，其中包含一组设备连接器(总体示为12)和一组电源连接器(总体示为30)。作为举例，但不限于这一优选实施例，所示设备连接器有一个配置成插座的连接器接口，而电源连接器配置成插头。当然，本领域技术人员将会理解，如果希望的话，设备连接器接口可包含插头，而电源连接器接口可包含插座。
如图1中所示，看到该组设备连接器12包含分离的和不同的设备连接器14，每个有一个外围轮廓体部分16，拥有多个电导体的终端，它们显示为公插脚18。四个(4)不同的设备连接器显示在20、22、24和26，各有额定功率0-5瓦、0-15瓦、0-25瓦和0-35瓦。每个设备连接器还有一个目标设备连接器适合于与目标便携电子设备配对。
类似地，该组电源连接器30包含单个电源连接器32，每个有外围轮廓体部分34，拥有多个电导体的各自终端，它们显示为母插脚36。在一个优选实施例中，单个电源连接器32被显示为连接器40、42、44和46，它们有各自的额定功率0-5瓦、0-15瓦、0-25瓦和0-35瓦。如图1中所示，额定功率0-5瓦的电源连接器40包含一个插头，只适于被接受到额定功率0-5瓦的设备连接器20中，其中插座20的外围轮廓体外形(profile)16适于接受插头40的外围轮廓体外形34。然而，额定功率0-15瓦的电源连接器有体外形34适于被接受到插座连接器20和22二者之中，因为电源连接器42至少有设备连接器额定功率那样大，因而能安全地与设备连接器20和22配对。
类似地，电源连接器44的额定功率是25瓦，这样，有体外形34适于耦合和接受到插座20、22和24中。由于电源连接器44的额定功率是25瓦，所以额定功率25瓦或低于25瓦的设备连接器14，即连接器20、22和24适于接受和安全地电耦合于电源连接器44。
在这一实施例中额定功率最高的电源连接器是电源连接器46，它有体外形轮廓34适于被接受到设备连接器20、22、24和26之内，因为这些设备连接器每个的额定功率在35瓦或低于35瓦，这处在或低于电源连接器46的额定功率。
仍参考图1，图中显示设备连接器外围轮廓体部分16全部是沿它们的右侧被键锁锁住(keyed)，其中额定功率5瓦的设备连接器20有由键锁部分(key portion)41定义的最大键锁开口，被配置成沿其右侧的一个凸起，使它能接受所有电源连接器40、42、44和46，如接下来将更详细显示的那样。
例如，看一看额定功率0-15瓦的设备连接器22，可以理解体外形16的键锁部分23低于设备连接器20的键锁部分21。这一键锁部分23机械上被配置成接收相应的连接器43的键锁部分42、连接器44的键锁部分45以及连接器46的键锁部分47，但不适合于接受连接器40的键锁部分41，因为电源连接器43的额定功率低于设备连接器22。
还能进一步理解，图中在29处显示用于额定功率35瓦设备连接器26的设备连接器26的附加外围轮廓体键锁部分。类似地，为35瓦额定功率的电源连接器46提供了外形34的第二外围轮廓体键锁部分49。35瓦设备连接器26和电源连接器46有这些附加键锁部分29和49，以保证35瓦设备连接器26只能与额定功率35瓦的电源连接器46配对。
现在参考图2，图中显示被配置成插头的额定功率5瓦的设备连接器40的透视图。外围轮廓体部分34包括体键锁部分41和用于进行键锁的对准片50，从而只能与设备连接器20连接，如前文描述的那样。还进一步看到电源连接器40包括电缆部分56，电缆部分56包括多个连接体，每个连接体耦合于和终接于母接口插脚36之一，这些插脚36适于从电源(如电源转换器)(未画出)接受供电。一个长形突起57，显示为一个凸片，横向延伸穿过连接器体58的上部，适于可放开地固定在设备连接器之一(如设备连接器20)内，从而使相应的体槽口31灵活地接受相应的向上突起57。类似的突起片57从体58的相对表面(未画出)延伸，它可以可放开地固定于相反槽口31内，如图3中所示。
设备连接器20的外围轮廓体部分16有槽口51，适于安全地接受在其中接受的电源连接器的相应凸片50，还有一个键锁部分53，适于接受其额定功率大于设备连接器20的5瓦额定功率的所有电源连接器。
参考图4，图中显示额定功率0-15瓦的电源连接器42，有键锁部分62和64被配置成只适于被额定功率5瓦的设备连接器20和额定功率15瓦的连接器22接受。
图5显示设备连接器22的透视图，设备连接器22有一个外围轮廓体部分16，其中包括键锁部分66和68。
现在参考图6，图中显示0-25瓦电源连接器44，其中外围轮廓体部分34有键锁部分72和74。这一电源连接器只能由设备连接器20、22和24接受。
参考图7，图中显示额定功率0-25瓦设备连接器24的透视图，其中外围轮廓体部分16有键锁部分76和78。额定功能0-25瓦的设备连接器只有适于耦合额定功率至少为25瓦的电源连接器，即额定功率0-25瓦的电源连接器44和0-35瓦的电源连接器46。
现在参考图8，图中显示额定功率0-35瓦的设备连接器46的透视图，其中外围轮廓体部分35有键锁部分82和84。
参考图9，图中显示0-35瓦设备连接器26，其中外围轮廓体部分16有键锁86和88。这一额定功率35瓦的设备连接器26只适于接受0-35瓦电源连接器46，因为连接器46的额定值是提供至少35瓦功率。
有利地，电源连接器40、42、44和46每个都向后兼容，这样，电源连接器32只能被接受到额定功率不大于所连接的电源连接器的那些设备连接器14中。有利地，有额定功率例如25瓦的目标便携电子设备只能与额定功率至少为25瓦的电源连接器连接，从而不会抽取超过电源连接器32额定功率的功率。
现在参考图10，图中显示一个额定功率0-5瓦的设备连接器20接受额定功率35瓦的电源连接器46的一例。设备连接器20和电源连接器46各自的键锁显示出不提供抵触匹配，从而允许把插头46安全地接受到插座20中。
参考图11，图中显示额定功率0-25瓦的设备连接器24接受额定功率35瓦的电源连接器44的一例。同样，插头44和插座24的各自键锁部分不提供抵触匹配，从而允许彼此可靠连接。
现在参考图12，图中显示额定功率0-15瓦的设备连接器22物理地与额定功率5瓦的电源连接器40抵触，该抵触示于90。该图显示电源连接器40的键锁部分41与设备连接器22的键锁部分23抵触。因为这种抵触，这两个连接器不能配对，这有利地保证较高额定功率的设备连接器14绝不能与较低额定功率的电源连接器连接。
参考图13，图中显示又一个举例，其中额定功率0-25瓦的设备连接器24将与额定功率5瓦的电源连接器40抵触。具体地说，电源连接器40的键锁部分41不能被接受到额定功率25瓦的设备连接器24之中，因为如图中所示，设备连接器键锁部分25与电源连接器40的键锁部分41抵触。
现在参考图14，图中在100显示一个包括额定功率0-15瓦设备连接器22(见图5)组装在机壳102中的末端连接器，以及一个便携电子设备连接器110。图中显示多个插脚18从插座104中伸出，插座104是包括键锁部分66和68的外围轮廓体部分16所拥有的。
现在参考图15，图中显示末端连接器100的透视后视图，描绘连接器110适于连接要被供电的便携电子设备。每个末端连接器100的形状和/或插脚输出都随设备而改变，取决于要供电的便携电子设备的接口要求以及末端连接器100的额定功率。
图16显示末端连接器100的端视图，进一步描绘插座104的外形，如前所述，在这一实施例中，插座104适于接受其额定功率为15瓦或15瓦以上的电源连接器。
图17显示末端连接器100的侧视图。图18显示面对连接器110的连接器100的端视图。图19是连接器100的顶视图，图20是连接器100的底视图。
现在参考图21，图中显示一个末端连接器100的一个实施例的电气示意图，显示对插脚18和便携电子设备连接器插脚每一个的一种可能的插脚输出赋值。如图21中所示，在包含电阻R1和R2的连接器14的插脚1、2和5之间建立了一个电阻性设备网络。选定电阻R1和R2之值以提供所希望的输出电压和所希望的输出电流。在这一实施例中显示了相关联的部件列表，被配置成所示输出电压为5.21伏+/-2.5％，输出电流0.45安+/-5％，其中电阻R1和R2是1％1/16瓦电阻器，使得末端连接器100被配置成额定功率8瓦的连接器。当然，对于适用于对不同电子设备供电的连接器，连接器110的特定插脚输出可能改变，因此部件值和设计参数被配置成满足这种要供电的便携电子设备的特定要求。
参考图22，图中显示图21所示末端连接器100的设备连接器14的端视图，而图23描绘图21所示实施例中的便携电子设备连接器110的端视图，显示出插脚1-4的插脚输出。
尽管已针对具体的优选实施例描述了本发明，但在读过本申请书后，许多改变和修改对于本领域技术人员而言将是显然的。所以，所附权利要求应在考虑现有技术的情况下被尽可能广义地解释，以包括所有这些变化和修改。
