具体实施方式
为使本申请的技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
导电连接件在插座内部作为导体来对电流进行传导，以下结合附图1对导电连接件在插座中的布置进行说明：
附图1示例了一种具有三个孔位的三级插座，如附图1所示，该三级插座包括：壳体2；位于壳体2上的插套座3和接线端子；以及位于插套座3上的导电连接件。其中，接线端子包括N(零线)极接线端子4-1、L(火线)极接线 端子4-2、E(零线)极接线端子4-3；对应地，导电连接件包括N极导电连接件1-1、L极导电连接件1-2、E极导电连接件1-3。
以N极导电连接件1-1举例来说，N极导电连接件1-1的一端与N极接线端子4-1连接，N极导电连接件1-1上对应于插座每一孔位的位置处分别连接有1个N极插套5-1。
进一步如附图2和附图3所示，N极导电连接件1-1和L极导电连接件1-2上均具有多个插套接点101，以插套接点101为界，各导电连接件均分为多个依次连接的连接段102，多个连接段102与插座上相应数量的插套一一对应(也就是说，每一连接段102对应多孔位插座的一个孔位)。
N极导电连接件1-1和L极导电连接件1-2利用其上的插套接点101来连接插套，其中，插套的数目、插座的孔位数目、连接段的数目彼此一一对应，以用来形成插座上的孔位。
为了便于描述，本申请实施将导电连接件中“与插座的接线端子邻接的连接段”称作第一连接段1021(其最接近插座的接线端子)，沿远离接线端子的方向，除第一连接段1021之外的其他连接段可以依次称作第二连接段1022、......第n连接段，其中，n≥3。
附图4示例了一种三孔位插座中N极导电连接件1-1和L极导电连接件1-2的各连接段的分布，如附图4所示，N极导电连接件1-1和L极导电连接件1-2分别与插座的N极接线端子4-1和L极接线端子4-2相邻的连接段均称为第一连接段1021，沿远离N极接线端子4-1和L极接线端子4-2的方向，两者其余的连接段依次称作第二连接段1022和第三连接段1023。
发明人研究发现，对于因导电连接件烧毁熔断而导致损坏的多孔位插座，导电连接件的熔断位置绝大部分(例如90％以上)靠近接线端子。
以图1所示的具有三个孔位的三极插座为例，其N极导电连接件1-1和L极导电连接件1-2上分别连接有3个N极插套5-1和3个L极插套5-2，以导电连接件和插套的插套接点为界，N极导电连接件1-1和L极导电连接件1-2均分为3个连接段，沿远离插座的N极接线端子4-1、L极接线端子4-2的方向，这3个连接段依次称作第一连接段1021、第二连接段1022、第三连接段1023(分别对应的孔位是1号孔位①、2号孔位②、3号孔位③)。发明人研究证实，N极导电连接件1-1和L极导电连接件1-2的熔断位置都集中于第一连接段1021。
三孔位插座一次性可最多供3个用电器取电，用户一次性使用1个、2个或 者3个用电器是随机的，并且用户每次使用该插座的哪个孔位也是随机的，根据排列组合，用户使用孔位情况、各连接段电流流经情况以及对应的概率如表1所示：
表1
Figure PCTCN2020095450-appb-000001
由表1可知，在用户使用的孔位随机，且每次使用多少个孔位也随机的情况下，电流流经L极导电连接件和N极导电连接件的第一连接段的概率是1，电流流经L极导电连接件和N极导电连接件的第二连接段的概率是6/7，电流流经L极导电连接件和N极导电连接件的第三连接段的概率是4/7。
可见，用户使用该三孔位插座时，电流流经L极导电连接件和N极导电连接件的第一连接段、第二连接段以及第三连接段的概率是不相同的，这就造成在其他条件相同的情况下，L极导电连接件和N极导电连接件的第一连接段、第二连接段以及第三连接段的熔断寿命是不一样的。因为电流流经L极导电连接件和N极导电连接件的第一连接段的概率最大，故随着该三孔位插座使用次数的增多，L极导电连接件和N极导电连接件的第一连接段最先达到极限寿命，即最先被烧毁熔断。
可见，对于多孔位插座，电流流经L极导电连接件和N极导电连接件的三个连接段的概率存在差异，这就会使得第一连接段最大频率地通断电流，而其他连接段随着其与接线端子的距离的增大，其通断电流的频率相对减小。因此，相对来说，导电连接件的第一连接段因电流发生升温熔断的几率最大。
如附图2及附图3所示，本申请实施例提供了一种导电连接件，其用于多孔位插座，该导电连接件包括多个连接段102，其中，多个连接段102依次连接，并与相应数量的插套一一对应。
多个连接段102中，第一连接段1021的电阻最小，其中，第一连接段1021为与插座的接线端子邻接的连接段102。
本申请实施例提供的导电连接件，由于导电连接件与插座的接线端子邻接 的连接段102(即第一连接段1021)通断电流的概率最大，熔断的概率也最大，通过使该第一连接段1021的电阻最小，来降低其烧毁熔断的几率，利于提高导电连接件整体的使用寿命。由于可以仅对影响导电连接件极限寿命的第一连接段1021进行改进，例如通过增加其横截面积的方式使其电阻最小，如此可避免材料浪费，利于降低成本。
本申请实施例中，导电连接件包括多个连接段102，也就是说，包括两个或两个以上的连接段102，例如，可以包括两个连接段102、包括三个连接段102(参见附图2和附图3)、包括四个连接段102、包括五个连接段102、包括六个连接段102等。
导电连接件与插座的接线端子邻接的端部一般形成有弯折结构103，利用弯折结构103与插座的接线端子连接。所以，本申请实施例所涉及的“沿远离接线端子的方向”也可以理解为沿远离导电连接件的弯折结构103的方向。
本申请实施例中，多个连接段102中，使第一连接段1021的电阻最小，对于其余连接段102，可以不进行改进，也可以对它们中的部分或者全部进行改进，使它们的电阻分别大于第一连接段1021的电阻。
作为一种示例，可以使第一连接段1021的电阻最小，同时，使第二连接段1022、......第n连接段的电阻相同且大于第一连接段1021的电阻(其中，n≥3)。
作为另一种示例，可以使第一连接段1021的电阻最小，同时，使第二连接段1022、......第n连接段的电阻部分相同(其中，n≥3)。
例如，当n＝5时，沿远离接线端子的方向，导电连接件包括依次连接的第一连接段，第二连接段、第三连接段、第四连接段、第五连接段，使第一连接段的电阻最小，使第二连接段、第三连接段、第四连接段、第五连接段中的任意两个或者三个的电阻相同。
作为再一种示例，可以使第一连接段1021的电阻最小，同时，使第二连接段1022、......第n连接段的电阻彼此不同。(其中，n≥3)。
例如，当n＝5时，沿远离接线端子的方向，导电连接件包括依次连接的第一连接段，第二连接段、第三连接段、第四连接段、第五连接段，使第一连接段的电阻最小，使第二连接段、第三连接段、第四连接段、第五连接段的电阻依次增大。
在一种可能的设计中，本申请实施例提供的导电连接件，沿远离接线端子的方向，多个连接段102的电阻可以依次增大，即，第一连接段1021、第二连 接段1022、......第n连接段的电阻依次增大(其中，n≥3)，如此，在降低导电连接件熔断烧毁几率的前提下，还可以最大化地降低成本(例如，使多个连接段的横截面积逐渐减小，以节省原料成本)。
可以使每个连接段102的电阻之比与电流流经每个连接段102的概率之比成反比，这样，沿远离接线端子的方向，由于电流流经各连接段102的概率逐渐减小，而各连接段102的电阻可以按比例逐渐增大，通过电流流经每一连接段102的概率，来确定当前连接段102相比在前连接段102的电阻的增加幅度(例如，来确定第二连接段1022的电阻相比第一连接段1021的电阻增加幅度)，以使导电连接件的每一连接段102的极限寿命达到一致，解决导电连接件的寿命存在水桶效应的问题，最大化节省成本。
举例来说，当导电连接件包括m个连接段102时(其中，m≥2)，设定第一连接段1021的电阻为R 1，并且，电流流经第一连接段1021的概率为定值1。设定第m连接段的电阻为R m，并且，电流流经第m连接段的概率为P m，则R m＝(R 1×1)÷P m。
可以通过改变连接段横截面积的方式来改变其电阻达到设计要求，也可以通过改变连接段电导率的方式来改变其电阻达到设计要求，针对以上两类实现方式分别进行阐述：
在一种可能的设计中，本申请实施例提供的导电连接件中，多个连接段102的电导率相同，且每个连接段102各自具有标准长度。多个连接段102中，第一连接段1021的横截面积最大。
在多个连接段102的电导率和长度固定的状态下，通过使第一连接段1021的横截面积最大，来达到使其电阻最小的目的。
需要说明的是，上述的“每个连接段102各自具有标准长度”指的是，在多孔位插座的孔位数目确定的前提下，其内包含的N极连接件和L极连接件的长度，以及上述各连接件中对应于每一孔位的连接段的长度均是确定的标准值，按照本领域通用的标准，即可确定连接件中每一连接段的长度，在该设计中，本申请实施例对连接段的长度不作改进。
基于上述设计，沿远离插座接线端子的方向，导电连接件中多个连接段102的横截面积可以依次减小，即，可以使各连接段102的体积减小，达到节省原料成本的目的。
进一步地，可以使连接段102的横截面积之比与电流流经每个连接段102 的概率之比成正比，这样，沿远离接线端子的方向，由于电流流经各连接段102的概率逐渐减小，使各连接段102的横截面积按上述比例逐渐减小，通过电流流经每一连接段的概率，来确定当前连接段相比在前连接段的横截面积的减小幅度，在保证导电连接件的每一连接段102的极限寿命达到一致的前提下，最大化地降低成本。
举例来说，当导电连接件包括m个连接段102时(其中，m≥2)，设定第一连接段1021的横截面积为S 1，并且，电流流经第一连接段1021的概率为定值1，设定第m连接段的电阻为S m，并且，电流流经第m连接段的概率为P m，则S m＝S 1×P m。
通过改变连接段的横截面尺寸的方式来改变各连接段的横截面积，以使第一连接段的横截面尺寸最大，其中，基于连接段的横截面形状，该横截面尺寸包括：长度、宽度和半径中的至少一种。
举例来说，当导电连接件的横截面形状为矩形时(例如，导电连接件为铜条)，被改变的横截面尺寸可以是横截面宽度和/或横截面长度。举例来说，当导电连接件的横截面形状为圆形时，被改变的横截面尺寸可以是半径。
以横截面形状为矩形的导电连接件为例(该结构的导电连接件可以称为连接条)，其包括m个电导率相同的连接段102(其中，m≥2)，并且每个连接段102各自具有标准长度。
可以相比相关技术增大该导电连接件的第一连接段1021的横截面积，并且使其横街面积在所有连接段102中最大。进一步地，还可以使其余连接段102的横截面积沿远离插座接线端子的方向依次减小，并且每一连接段102的横截面积的减小幅度由电流流经该连接段的概率所决定。
在一种可能的设计中，本申请实施例提供的导电连接件的多个连接段102的横截面形状均为矩形，且多个连接段102的横截面长度相同，可以使第一连接段1021的横截面宽度W 1最大，且W 1的取值范围为：0.5mm＜W 1＜0.65mm。第一连接段1021的横截面宽度W 1在如上范围内时，不仅可以降低电阻，提高导电连接件极限寿命，同时还满足多孔位插座的设计要求。
示例地，第一连接段1021的横截面宽度W 1可以为0.51mm、0.52mm、0.53mm、0.54mm、0.55mm、0.56mm、0.57mm、0.58mm、0.59mm、0.60mm、0.61mm、0.62mm、0.63mm、0.64mm等。
本申请实施例中，如附图5所示，连接段的横截面长度L指的是其横截面 长度相对较长的边的长度(还可以理解为是连接段的宽度)，横截面宽度W指的是其横截面长度相对较短的边的长度(还可以理解为是连接段的厚度)。
进一步地，如附图6及附图7所示，沿远离接线端子的方向，可以使剩余连接段102的横截面宽度依次减小。
当各连接段102的横截面长度相同时，设定第一连接段1021的横截面宽度W 1，根据电流流经每一连接段102的概率，可以采用以下公式确定除第一连接段1021之外的其他连接段的横截面宽度W m：
W m＝电流流经当前连接段的概率P m×W 1。
在另一种可能的设计中，本申请实施例提供的导电连接件的多个连接段102的横截面形状均为矩形，且多个连接段102的横截面宽度相同，可以使第一连接段1021的横截面长度L 1最大，且横截面长度L 1的取值范围为：3.6mm＜L 1＜4.5mm。第一连接段1021的横截面长度L 1在如上范围内时，不仅可以降低电阻，提高导电连接件的极限寿命，同时还满足多孔位插座的设计要求。
示例地，第一连接段1021的横截面长度L 1可以为3.72mm、3.75mm、3.78mm、3.8mm、3.85mm、3.9mm、3.95mm、4mm、4.05mm、4.1mm、4.15mm、4.2mm、4.25mm、4.3mm、4.35mm、4.4mm等。
进一步地，如附图8及附图9所示，沿远离插座接线端子的方向，可以使剩余的多个连接段102的横截面长度依次减小。
当各连接段102的横截面宽度相同时，设定第一连接段1021的横截面长度为L 1，根据电流流经每一连接段102的概率，可以采用以下公式确定除第一连接段1021之外的其他连接段的横截面长度L m：
L m＝电流流经当前连接段的概率P m×L 1。
在再一种可能的设计中，本申请实施例提供的导电连接件的多个连接段102的横截面形状均为矩形，且多个连接段102的横截面宽度和横截面长度均不同，使第一连接段1021的横截面积S 1最大，且横截面积S 1的取值范围为：1.8mm 2＜S 1＜2.5mm 2。第一连接段1021的横截面积S 1在如上范围内时，不仅可以降低电阻，提高导电连接件的极限寿命，同时还满足多孔位插座的设计要求。
示例地，第一连接段1021的横截面积S 1可以为1.9mm 2、1.95mm 2、2.0mm 2、2.1mm 2、2.2mm 2、2.3mm 2、2.35mm 2、2.4mm 2等。
进一步地，沿远离接线端子的方向，可以使剩余的多个连接段102的横截面积依次减小。
设定第一连接段1021的横截面积为S 1，根据电流流经每一连接段102的概率，可以采用以下公式确定除第一连接段1021之外的其他连接段的横截面积为S m：
S m＝电流流经当前连接段的概率P m×S 1。
当第一连接段1021横截面积S 1确定时，任意设定其横截面长度或者横截面宽度中的一个为定值，则可相应地计算得到另一个。
在再一种可能的设计中，本申请实施例提供的导电连接件的多个连接段102的横截面形状均为圆形，且第一连接段1021的半径R 1的取值范围为：0.757mm＜R 1＜0.892mm，即第一连接段1021的横截面积S 1的取值范围为：1.8mm 2＜S 1＜2.5mm 2。
使第一连接段1021的半径R 1在如上范围内时，不仅可以降低电阻，提高导电连接件的极限寿命，同时还满足多孔位插座的设计要求。
示例地，第一连接段的半径R 1可以为0.76mm、0.77mm、0.78mm、0.79mm、0.8mm、0.81mm、0.82mm、0.83mm、0.84mm、0.85mm、0.86mm、0.87mm、0.88mm、0.89mm等。
进一步地，沿远离接线端子的方向，可以使剩余的多个连接段102的半径依次减小。
设定第一连接段1021的半径R 1，根据电流流经每一连接段102的概率，可以采用以下公式确定除第一连接段1021之外的其他连接段的半径为R m：
R m＝(P m) 1/2×R 1。
对于横截面为圆形的导电连接件，该结构的导电连接件可以包括一整根导体，也可以包括多根导线。当包括多根导线时，上述连接段的半径指的是多根圆形截面导线的半径之和。
以下结合上述各种可能的设计，分别提供一示例性的用于三孔位插座的导电连接件，用于说明本申请实施例提供的导电连接件的结构及成本相比相关技术提供的导电连接件的优势：
如附图10和附图11所示，三孔位插座包括：N极导电连接件1-1、L极导电连接件1-2，以及可选的地极导电连接件1-3。沿远离插座的接线端子的方向，三孔位插座包括：1号孔位、2号孔位、3号孔位，如附图2和附图3所示，导电连接件上对应的连接段102分别是第一连接段1021、第二连接段1022、第三 连接段1023。其中，电流流经N极导电连接件1-1和L极导电连接件1-2的第一连接段1021的概率是1，电流流经N极导电连接件1-1和L极导电连接件1-2的第二连接段1022的概率是6/7，电流流经N极导电连接件1-1和L极导电连接件1-2的第三连接段1023的概率是4/7。
(1)作为示例一，如附图6和附图7所示，本申请实施例提供了连接段横截面积为矩形的导电连接件，沿远离接线端子的方向，其所包含的三个连接段102的横截面长度相同，横截面宽度依次减小。
一方面，由于本申请实施例提供的导电连接件的成本须小于相关技术提供的导电连接件的成本，这就使得本申请实施例提供的导电连接件的体积小于相关技术提供的导电连接件的体积；另一方面，本申请实施例提供的导电连接件的极限寿命须大于相关技术提供的导电连接件的极限寿命，这就使得本申请实施例提供的导电连接件中第一连接段的横截面宽度大于相关技术提供的导电连接件的横截面宽度(相关技术提供的导电连接件的整体横截面宽度是一致的)。
基于以上两个方面，可以获得本申请实施例提供的导电连接件中第一连接段的横截面宽度W 1的取值范围，由该取值范围内任意取值均可作为第一连接段的横截面宽度。第一连接段的横截面宽度确定后，根据电流流经每一连接段的概率，除第一连接段1021之外的其他连接段的横截面宽度W  m也随之确定。
如附图6所示，对于本申请实施例提供的N极导电连接件1-1，各连接段的横截面长度均为3.6mm，第一连接段1021、第二连接段1022、第三连接段1023的长度分别为55mm、42mm、43mm(以上三个连接段的长度属于N极导电连接件的一个标准尺寸，即，对于N极导电连接件1-1，第一连接段1021、第二连接段1022、第三连接段1023分别具有标准长度55mm、42mm、43mm)。
以相关技术提供的对于N极导电连接件作为对比，设定其各连接段的横截面长度均为3.6mm，横截面宽度均为0.5mm，第一连接段、第二连接段、第三连接段的长度分别为55mm、42mm、43mm(总长为140mm)。
如附图7所示，对于本申请实施例提供的L极导电连接件1-2，设定各连接段103的横截面长度均为3.6mm，第一连接段1021、第二连接段1022、第三连接段1023的长度分别为44mm、42mm、42mm(以上三个连接段的长度属于L极导电连接件的一个标准尺寸，即，对于L极导电连接件1-2，第一连接段1021、第二连接段1022、第三连接段1023分别具有标准长度44mm、42mm、42mm)。
以相关技术提供的L极导电连接件作为对比，设定其各连接段的横截面长 度均为3.6mm，横截面宽度均为0.5mm，第一连接段、第二连接段、第三连接段的长度分别为44mm、42mm、42mm(总长为128mm)。
(1.1)对于本申请实施例提供的L极导电连接件1-2的第一连接段1021的横截面宽度W 1，其通过以下方式计算得到：
其一，本申请实施例提供的L极导电连接件的体积＜相关技术提供的L极导电连接件的体积，这就使得(3.6×W 1×44)+(3.6×6/7×W 1×42)+(3.6×4/7×W 1×42)＜(3.6×0.5×128)，确定W 1＜0.615mm。
其二，本申请实施例提供的L极导电连接件的第一连接段的横截面宽度＞相关技术提供的L极导电连接件的横截面宽度，这就使得W 1＞0.5mm。
综上可知，本申请实施例提供的L极导电连接件1-2的第一连接段1021的横截面宽度W 1的取值范围是：0.5mm＜W 1＜0.615mm，在该范围内任意取值均可作为L极导电连接件1-2的第一连接段1021的横截面宽度W 1，例如，0.55mm、0.58mm、0.60mm、0.61mm等。
根据电流流经每一连接段的概率，确定L极导电连接件1-2的第二连接段1022的横截面宽度W 2和第三连接段1023的横截面宽度W 3，其计算公式分别如下：
本申请实施例提供的L极导电连接件1-2的第二连接段1022的横截面宽度W 2＝6/7×W 1，第三连接段1023的横截面宽度W 3＝4/7×W 1。
作为示例，设定本申请实施例提供的L极导电连接件1-2的第一连接段1021的横截面宽度W 1为0.6mm，则第二连接段1022的横截面宽度W 2为0.514mm，第三连接段1023的横截面宽度W 3为0.343mm。
基于以上数据，来计算三孔位插座的L极导电连接件相比相关技术所减少的成本，如下所示：
(1)本申请提供的L极导电连接件的体积V＝(44mm×3.6mm×0.6mm)+(42mm×3.6mm×0.514mm)+(42mm×3.6mm×0.343mm)＝224.6mm 3。
(2)相关技术提供的L极导电连接件的体积V＝128mm×3.6mm×0.5mm＝230.4mm 3。
可见，本申请实施例的L极导电连接件的体积相比相关技术减少5.8mm 3。
以L极导电连接件的密度为8.5g/cm 3，单价为41.14元为例，本申请实施例提供的L极导电连接件的重量相比相关技术的减少量△M＝8.5g/cm 3×5.8mm 3＝0.05g，则其成本相比相关技术的减少量△P＝0.05g×41.14元/kg＝0.0021元。
(1.2)对于本申请实施例提供的N极导电连接件1-1，按照上述相同的方法，可以计算得到本申请实施例提供的N极导电连接件1-1的第一连接段1021的横截面宽度W 1的取值范围是：0.5mm＜W 1＜0.606mm，在该范围内任意取值均可作为N极导电连接件1-1的第一连接段1021的横截面宽度W 1，例如，0.52mm、0.55mm、0.58mm、0.60mm等。
作为示例，设定本申请实施例提供的N极导电连接件1-1的第一连接段1021的横截面宽度W 1为0.6mm，则第二连接段1022的横截面宽度W 2为0.514mm，第三连接段1023的横截面宽度W 3为0.343mm。
基于以上数据，来计算三孔位插座的N极导电连接件相比相关技术所减少的成本，如下所示：
(1)本申请实施例提供的N极导电连接件的体积V＝55mm×3.6mm×0.6mm+42mm×3.6mm×0.514mm+43mm×3.6mm×0.343mm＝249.6mm 3。
(2)相关技术提供的N极导电连接件的体积V＝140mm×3.6mm×0.5mm＝252mm 3。
可见，本申请实施例的N极导电连接件的体积相比相关技术减少2.4mm 3。
以N极导电连接件的密度为8.5g/cm 3，单价为41.14元为例，本申请实施例提供的N极导电连接件的重量相比相关技术的减少量△M＝8.5g/cm 3×2.4mm 3＝0.02g，则其成本相比相关技术的减少量△P＝0.02g×41.14元/kg＝0.008元。
综上，当采用本申请实施例提供的导电连接件时，单个三孔位插座的导电连接件的材料使用量及成本相比相关技术均显著降低。
(2)作为示例二，如附图8和附图9所示，本申请实施例提供了这样一种连接1，其所包含的三个连接段102的横截面宽度相同，横截面长度依次减小。
一方面，由于本申请实施例提供的导电连接件的成本须小于相关技术提供的导电连接件的成本，这就使得本申请实施例提供的导电连接件的体积小于相关技术提供的导电连接件的体积；另一方面，本申请实施例提供的导电连接件的极限寿命须大于相关技术提供的导电连接件的极限寿命，这就使得本申请实施例提供的导电连接件中第一连接段的横截面长度大于相关技术提供的导电连接件的横截面长度(相关技术提供的导电连接件的横截面长度整体是一致的)。
基于以上两个方面，可以获得本申请实施例提供的导电连接件中第一连接段的横截面长度L 1的取值范围，由该取值范围内任意取值均可作为第一连接段 的横截面长度。第一连接段的横截面长度确定后，根据电流流经每一连接段的概率，除第一连接段1021之外的其他连接段的横截面长度L m也随之确定。

其二，本申请实施例提供的L极导电连接件的第一连接段的横截面长度＞相关技术提供的L极导电连接件的第一连接段的横截面长度，这就使得L 1＞3.6mm。

根据电流流经每一连接段的概率，确定L极导电连接件1-2的第二连接段1022的横截面长度L 2和第三连接段1023的横截面长度L 3，其计算公式分别如下：
本申请实施例提供的L极导电连接件的第二连接段的横截面长度L 2＝6/7×L 1，第三连接段的横截面长度L 3＝4/7×L 1。
作为示例，设定本申请实施例提供的L极导电连接件1-2的第一连接段1021的横截面长度为3.8mm，则第二连接段1022的横截面长度为3.257mm，第三连接段1023的横截面长度为2.171mm。
基于以上数据，来计算三孔位插座的L极导电连接件相比相关技术所减少的成本，如下所示：

(2)相关技术提供的L极导电连接件的体积V＝128mm×3.6mm×0.5mm＝230.4mm 3。
可见，本申请实施例提供的L极导电连接件的体积相比相关技术减少32.8mm 3。
以L极导电连接件的密度为8.5g/cm 3，单价为41.14元为例，本申请实施例提供的L极导电连接件的重量相比相关技术的减少量△M＝8.5g/cm 3×32.8mm 3＝0.279g，则其成本相比相关技术的减少量△P＝0.279g×41.14元/kg＝0.0115元。
(2.2)对于N极导电连接件1-1，按照上述相同的方法，可以计算得到本申请实施例提供的N极导电连接件1-1的第一连接段1021的横截面长度L 1的取值范围是：3.6mm＜L 1＜4.361mm，在该范围内任意取值均可作为N极导电连接件1-1的第一连接段1021的横截面长度L 1，例如，3.7mm、3.8mm、4.0mm、4.2mm等。

(2)相关技术提供的N极导电连接件的体积V＝140mm×3.6mm×0.5mm＝252mm 3。
可见，本申请实施例提供的N极导电连接件的体积相比相关技术减少32.4mm 3。
以N极导电连接件的密度为8.5g/cm 3，单价为41.14元为例，本申请实施 例提供的N极导电连接件的重量相比相关技术的减少量△M＝8.5g/cm 3×32.4mm 3＝0.275g，则其成本相比相关技术的减少量△P＝0.0275g×41.14元/kg＝0.0113元。

设定第一连接段的横截面积为S 1，根据电流流经每一连接段的概率，确定除第一连接段1021之外的其他连接段的横截面积S m＝电流流经当前连接段的概率P m×第一连接段的横截面积S 1。
一方面，由于本申请实施例提供的导电连接件的成本须小于相关技术提供的导电连接件的成本，这就使得本申请实施例提供的导电连接件的体积小于相关技术提供的导电连接件的体积；另一方面，本申请实施例提供的导电连接件的极限寿命须大于相关技术提供的导电连接件的极限寿命，这就使得本申请实施例提供的导电连接件中第一连接段的横截面积要大于相关技术导电连接件的第一连接段的横截面积。
基于以上两个方面，可以获得本申请实施例提供的导电连接件中第一连接段的横截面积S 1的取值范围，由该取值范围内任意取值均可作为第一连接段的横截面积。第一连接段的横截面积确定后，根据电流流经每一连接段的概率，除第一连接段1021之外的其他连接段的横截面积S 1也随之确定。相应地，每一连接段的宽度和横截面宽度也随横截面积的确定而确定。

作为示例，可以使本申请实施例提供的L极导电连接件的第一连接段的横截面积为2.1mm 2，则第二连接段的横截面积为1.8mm 2，第三连接段的横截面积为1.2mm 2。

(3.2)对于本申请实施例提供的N极导电连接件的S 1，按照上述相同的方法，可以计算得到本申请实施例提供的N极导电连接件的第一连接段的横截面积S 1的取值范围是：1.8mm 2＜S 1＜2.180mm 2，在该范围内任意取值均可作为N极导电连接件的第一连接段的横截面积，例如，例如，1.9mm 2、2mm 2、2.1mm 2、 2.15mm 2等
作为示例，可以使本申请实施例提供的N极导电连接件的第一连接段的横截面积为2.1mm 2，则第二连接段的横截面积为1.8mm 2，第三连接段的横截面积为1.2mm 2。

需要说明的是，上述的“每个连接段各自具有标准几何尺寸”指的是，在多孔位插座的孔位数目确定的前提下，其内包含的N极连接件和L极连接件中 对应于每一孔位的连接段的几何尺寸均可以是确定的标准值，按照本领域通用的标准，即可确定连接件中每一连接段的几何尺寸。
在一种可能的设计中，沿远离接线端子的方向，多个连接段的电导率依次减小。
其中，导电连接件中多个连接段的横截面长度(或者横截面宽度)可以相同，也可以不同。为了便于成型制备，可以使多个连接段的横截面长度相同，横截面宽度也相同。
以三孔位插座举例来说，其导电连接件包括第一连接段、第二连接段、第三连接段。
可以使第一连接段的材质为紫铜，第二连接段的材质为磷青铜，第三连接段的材质为黄铜，以上三者的电导率沿远离接线端子的方向逐渐减小，可以平衡导电连接件的不同连接段因电流流经次数的不同而导致的寿命差异，有效改善导电连接件寿命存在的水桶效应问题，提高导电连接件的整体寿命。

L极导电连接件和N极导电连接件可以采用相同的方式改变其各连接段的电阻，例如，均采用改变横截面长度或横截面宽度的方式，或者，均采用改变材质的方式。为了便于提高制备效率，简化制备流程，可以使L极导电连接件和N极导电连接件采用相同的方式改变其各连接段的电阻。
L极导电连接件和N极导电连接件还可以采用不同的方式改变其各连接段的电阻，例如，其中一个采用改变横截面长度的方式，而另一个采用改变横截面宽度的方式，或者，其中一个采用改变横截面长度或横截面宽度的方式，而另一个采用改变材质的方式。

对于本申请实施例涉及的任一种导电连接件的制备，可以参见以下制备方法：
获取导电连接件中第一连接段的尺寸，其获取方式例如可以参照上述示例一、示例二或者示例三中所述的方法。
进一步地，根据第一连接段的尺寸，确定导电连接件中其余连接段的尺寸。
根据各连接段的尺寸，来制备导电连接件。
其中，根据第一连接段的尺寸，确定导电连接件中其余连接段的尺寸，可以包括以下：
根据导电连接件中所包含的连接段的数目(即，多孔位插座的孔位数目)，可以确定不同孔位使用情况下电流所流经的连接段，进而可以确定电流流经每一连接段概率。
由于连接段的横截面积之比与电流流经每个连接段的概率之比成正比，根据第一连接段的尺寸，以及电流流经除第一连接段1021之外的其他连接段的概率，可以分别计算得到其余连接段的尺寸，进而用于指导导电连接件的制备。
可以理解的是，导电连接件中连接段的数目与其所在多孔位插座的孔位数目一致，例如，为m个(m≥3)，则用户使用插座时，孔位使用状态的数目Y可以采用以下公式计算得到：
Figure PCTCN2020095450-appb-000002
针对以上孔位使用状态数，分别确定电流流经每一连接段的概率，例如，电流流经第一连接段的概率为P 1＝1，流经第二连接段的概率为P 2＝(Y-1)/Y，流经第m连接段的概率为P m＝X/Y，只需计算出在Y个孔位使用状态中，电流流经第m连接段的次数X，即可得到P m。
以常见的两孔位插座举例，电流流经第一连接段、第二连接段的概率分别为1、2/3。
以常见的三孔位插座举例，电流流经第一连接段、第二连接段、第三连接段的概率分别为1、6/7、4/7。
