发明内容

与现有技术相比，本申请的特点及优点是：

根据上述优点，为能进一步的了解本申请，故公开一较佳的实施方式如下，配合附图、标号，将本申请的技术方案及其所达成的功效进行如下详细说明。
为方便理解本申请提供的电连接器，首先说明本申请提供的电连接器的应用场景，本申请提供的电连接器应用于将两个导体(如电连接装置)连接起来。
本文所使用的术语：
悬臂梁，是指在梁的一端是固定支座，梁的另一端为自由端。
如图1至图3所示，本申请提供的一种电连接器，包括壳体1和第一导电单元2；该壳体1具有间隔设置的用于插入第一电连接装置8的第一开口11和用于插入第二电连接装置9的第二开口12，壳体1朝向第一开口11的侧壁上设有第一插入部13；该第 一导电单元2能与第一电连接装置8和/或第二电连接装置9电性连接，至少部分第一导电单元2收容于壳体1内，在第一电连接装置8或第二电连接装置9从壳体1外经第一插入部13插入至壳体1内的状态下，第一电连接装置8或第二电连接装置9能与被收容的至少部分第一导电单元2电性连接。
本申请的电连接器，通过在壳体1朝向第一开口11的侧壁上设置第一插入部13，由于在第一电连接装置8或第二电连接装置9从壳体1外经第一插入部13插入至壳体1内的状态下，第一电连接装置8或第二电连接装置9能与被收容的至少部分第一导电单元2电性连接，因此，第一电连接装置8和第二电连接装置9除了能从第一开口11和第二开口12分别插入至壳体1并与第一导电单元2电性连接外，第一电连接装置8或第二电连接装置9还可从第一开口11处的第一插入部13插入壳体1并与第一导电单元2电性连接，由此，通过上述结构，本申请的电连接器可实现第一电连接装置8和/或第二电连接装置9至少在两个不同的角度与电连接器进行配合。
具体的，该壳体1可为中空的长方体结构，该第一插入部13可为设置在壳体1上的缺口，该缺口与第一开口11相连通，至少部分的第一导电单元2例如通过焊接、粘接、螺纹连接或者卡接等方式设置在壳体1内。在实际使用中，第一电连接装置8和第二电连接装置9可分别从第一开口11和第二开口12插入至壳体1中，从而使第一电连接装置8和第二电连接装置9与壳体1的第一导电单元2电性连接；可选的，第一电连接装置8或第二电连接装置9也可与第一开口11连通的第一插入部13插入至壳体1内，从而使经第一插入部13插入的第一电连接装置8或第二电连接装置9能与壳体1内的第一导电单元2电性连接。
进一步的，如图1和图2所示，壳体1朝向第一开口11的侧壁上还设有第二插入部14，沿垂直于第一电连接装置8或第二电连接装置9插入第一开口11的方向O，该第二插入部14与第一插入部13相对设置。具体的，第二插入部14也可为设置在壳体1上的缺口，该缺口与第一开口11相连通。
本申请通过在壳体1朝向第一开口11的侧壁上设有与第一开口11连通的第一插入部13和第二插入部14，使得第一电连接装置8或第二电连接装置9除了可从第一开口11、第二开口12或第一插入部13插入至壳体1内，还可从第二插入部14插入至壳体1内，从而实现从多角度与第一导电单元2进行电性连接，进一步丰富第一电连接装置8或第二电连接装置9与电连接器的配合方式。
壳体1的材质可以为塑料材质或者金属材质，可以使用导电性好的材质也可以使用 导电性差的材质，例如可以是钢材质，也可以使用含有钢的材质。本申请的第一插入部13和/或第二插入部14，一方面，可使第一电连接装置8和第二电连接装置9能分别沿方向O插入壳体1，还可实现第一电连接装置8或第二电连接装置9从壳体1的侧方插入，如图5所示；当然，作为可选的，第一电连接装置8或第二电连接装置9也可从沿着壳体1的斜向方向P插入，从而进一步丰富了第一电连接装置8或第二电连接装置9与电连接器的配合方式；另一方面，本申请更加便于加工，例如可直接对壳体1的第一开口11处的端部切割，即可形成第一插入部13和/或第二插入部14。
在一个可行的实施例中，第一插入部13或第二插入部14还可以是设置在靠近壳体1的第一开口11或第二开口12处的形成在壳体1侧壁上的孔，如方形通孔等；具体实施时，该孔的周壁可以对第一电连接装置8或第二电连接装置9起到限位作用。此外，为了达到防水防尘的效果，在一些实施例中，还可在壳体1上的第一插入部13和/或第二插入部14的周壁上铰接一个防水板或防尘板，将防水板或防尘板封设在第一插入部13或第二插入部14处，达到防水或防尘的效果。
进一步的，如图4所示，壳体1具有用于置入第一导电单元2的安装口15，在第一导电单元2经安装口15插入至壳体1内的状态下，位于安装口15处的壳体1的侧壁弯折后能闭合安装口15。通过设置安装口15可快速将第一导电单元2置入壳体1内，装配简单，便于拆装。
具体的，该壳体1在成型前呈板状，沿着板的宽度方向Q折弯后可形成一个大体呈“匚”形的结构体，该“匚”形的结构体的开口即为安装口15，在组装电连接器时，直接将第一导电单元2从壳体1的外部经该安装口15置入至壳体1内，然后闭合上该安装口15即可。
在本申请中，壳体1成型前包括沿宽度方向Q相对设置的第一侧17和第二侧18，第一侧17和第二侧18中的一个上例如通过焊接、粘接或一体冲压成型等方式设有呈燕尾形状的凸起171，第一侧17和第二侧18中的另一个上设有与凸起171形状相匹配的燕尾槽181，凸起171能与燕尾槽181相扣合。
进一步的，见图11至图12所示，壳体1还包括用于对第一导电单元2提供预紧力的夹紧部件16。通过设置夹紧部件16，可使插入至壳体1的第一电连接装置8或第二电连接装置9被夹持的更紧，保证电连接器在震动环境下的连接可靠性。
在本申请中，夹紧部件16包括位于第一开口11处的至少一个第一壳体弹性臂161和位于第二开口12处的至少一个第二壳体弹性臂162；其中，第一壳体弹性臂161包括 能伸入壳体1内并与第一导电单元2抵接的第一自由端1611；第二壳体弹性臂162包括能伸入壳体1内并与第一导电单元2抵接的第二自由端1622。
具体的，第一壳体弹性臂161和第二壳体弹性臂162可位于壳体1的同一侧，例如，如图1所示的壳体1的上表面；或者第一壳体弹性臂161和第二壳体弹性臂162可位于壳体1的不同侧，例如，第一壳体弹性臂161位于壳体1的上表面，第二壳体弹性臂162位于壳体1的下表面。
以第一电连接装置8经第一开口11插至壳体1内并与第一导电单元2电性连接，第二电连接装置9经第二开口12插至壳体1内并与第一导电单元2电性连接为例，通过设置夹紧部件16，随着第一电连接装置8插入至第一开口11，由于第一电连接装置8具有一定的厚度，如图12所示，第一电连接装置8能使第一导电单元2沿壳体1的厚度方向H朝靠近相邻的壳体1的内壁方向运动，此时位于第一开口11处的第一壳体弹性臂161会对第一电连接装置8起到夹持的作用，同理，第二壳体弹性臂162会对插入第二开口12的第二电连接装置9夹持的更紧。
第一壳体弹性臂161施加到第一电连接装置8上的压力范围为0.3N-95N；第二壳体弹性臂162施加到第二电连接装置9上的压力范围为0.3N-95N。
为了验证第一壳体弹性臂161施加到第一电连接装置8上的压力对第一壳体弹性臂161和第一电连接装置8之间的接触电阻的影响，或者第二壳体弹性臂162施加到第二电连接装置9上的压力对第二壳体弹性臂162和第二电连接装置9之间的接触电阻的影响，申请人进行了针对性测试，以第一壳体弹性臂161施加到第一电连接装置8的压力为例，申请人选用了相同形状、相同尺寸的第一壳体弹性臂161和第一电连接装置8，并将第一壳体弹性臂161和第一电连接装置8之间的压力设计为不同的压力，来观察第一壳体弹性臂161和第一电连接装置8之间的接触电阻。
接触电阻的检测方式为使用微电阻测量仪，在第一壳体弹性臂161和第一电连接装置8接触位置上进行电阻的测量，并读取微电阻测量仪上的数值，在本实施例中，接触电阻小于50μΩ为理想值。
表1：不同壳体弹性臂和电连接装置的压力对接触电阻影响
Figure PCTCN2022142643-appb-000001
从表1可以看出，当第一壳体弹性臂161和第一电连接装置8之间的压力小于0.3N时，由于结合力太小，两者之间的接触电阻要高于理想值，不符合要求。第一壳体弹性臂161和第一电连接装置8之间的压力大于95N时，接触电阻并无明显降低，而选材及加工却更加困难，而且压力过大也会对第一电连接装置8造成损伤。因此，申请人设定第一壳体弹性臂161施加到第一电连接装置8的上压力范围为0.3N-95N；第二壳体弹性臂162施加到第二电连接装置9的上压力范围为0.3N-95N。
另外，申请人发现当第一壳体弹性臂161和第一电连接装置8之间的压力大于0.5N时，第一壳体弹性臂161与第一电连接装置8之间的接触电阻值比较良好，降低的趋势很快，而第一壳体弹性臂161和第一电连接装置8之间的压力小于50N，导电弹片的制造、安装、使用都很方便，成本也很低，因此，申请人优选第一壳体弹性臂161施加到第一电连接装置8的上压力范围为0.5N-50N；第二壳体弹性臂162施加到第二电连接装置9的上压力范围为0.5N-50N。
根据本申请的一个实施方式，如图5至图7、以及图1所示，该电连接器还包括用于固定壳体1和第一导电单元2的固定部件3，该固定部件3设置在壳体1和第一导电单元2之间。通过设置固定部件3，不仅便于拆装第一导电单元2，而且还可对第一导电单元2起到限位作用。
在一可行的实施例中，如图6所示，固定部件3包括能拆卸相连的第一固定部31和第一固定配合部32；其中，第一固定部31为例如通过焊接、粘接、螺纹连接、卡接或一体冲压成型等方式设置在第一导电单元2上的第一凸件，第一固定配合部32为开设在壳体1上的第一凹件。
在另一可行实施例中，固定部件3包括能拆卸相连的第一固定部31和第一固定配合部32；其中，第一固定部31为例如通过焊接、粘接、螺纹连接、卡接或一体冲压成型设置在壳体1上的第一凸件，第一固定配合部32为开设在第一导电单元2上的第一凹件。
通过设置第一固定部31和第一固定配合部32，不仅结构简单，而且无需借助其他工具(如胶条或焊条等)，徒手即可快速完成第一导电单元2与壳体1的拆装。
根据本申请的一个实施方式，如图8至图9所示，壳体1内设有两个第一导电单元2，两个第一导电单元2沿壳体1的厚度方向H间隔设置。通过设置两个第一导电单元2，以对第一电连接装置8和第二电连接装置9起到双向夹持的作用；相较于只有一个第一导电单元2的电连接器，以片式电连接装置为例，通过设置两个第一导电单元2， 可以使得片式电连接装置的两面均与第一导电单元2接触，提高电连接装置电性连接第一导电单元2的可靠性。
进一步的，如图7至图9所示，两个第一导电单元2之间连接有呈条状的支撑部4，支撑部4位于两个第一导电单元2的同一侧上。通过设置支撑部4，可以提高第一导电单元2的加工速度，即，在壳体1成型前将两个处于同一平面的第一导电单元2通过支撑部4对折即可同时完成两个第一导电单元2的加工；另外，由于支撑部4是位于上下两个第一导电单元2的同一侧上，因此还便于对两个第一导电单元2加工，提高加工速度；再有，由于支撑部4是连接在两个第一导电单元2的同一侧上，因此，每个第一导电单元2相当于一个悬臂梁结构，也即，在外界压力的作用下，两个第一导电单元2可沿壳体1的厚度方向H相互靠近并发生变形，使得体积减小，进而便于将两个第一导电单元2经安装口15置入至壳体1内，不会与壳体1发生干涉。
在本申请中，如图9所示，第一导电单元2包括位于第一开口11的多个第一弹性臂21，多个第一弹性臂21沿垂直于第一电连接装置8或第二电连接装置9插入第一开口的方向Q间隔设置，两两相邻的第一弹性臂21之间具有第一间隙22。
通过将至少两个第一弹性臂21沿垂直于第一电连接装置8或第二电连接装置9插入第一开口的方向Q间隔设置，以节省物料，降低生产制造成本；另外，由于物料减少了，故其与第一电连接装置8的接触面积减少了，因此还能有效降低接触的温升值(或可称温度阈值)和接触的电阻值。
具体的，第一间隙22的宽度是第一弹性臂21的宽度的1％-100％。
为了验证相邻第一间隙22的间隔距离对电连接器接触电阻的影响，选用相同形状、尺寸的第一导电单元2和壳体1组成的电连接器，相同形状和尺寸的第一电连接装置8及第二电连接装置9，并将电连接器与第二电连接装置9连接，来观测第一电连接装置8与电连接器之间的接触电阻。
接触电阻的检测方式为使用微电阻测量仪，在第一电连接装置8与电连接器接触位置上进行电阻的测量，并读取微电阻测量仪上的数值，在本实施例中，接触电阻小于50μΩ为理想值。
表2：第一间隙22的间隔距离(宽度)对第一电连接装置8和电连接器结构之间接触电阻的影响
Figure PCTCN2022142643-appb-000002
从表2可以看出，第一间隙22的间隔距离(宽度)占第一弹性臂21的宽度的比值大于100％时，由于接触电阻大于50μΩ，因此不符合要求，另外电连接器结构现有的加工方式为冲压或者切割加工，第一间隙22的间隔距离(宽度)如果太窄，不容易加工，综上把第一间隙22间隔距离(宽度)定义为第一弹性臂21宽度的1％-100％。
进一步的，如图9所示，各第一弹性臂21包括自第一开口11至第二开口12依序连接的第一翘曲段211和第一连接段212，第一翘曲段211朝向第一开口11的外边缘倾斜设置。
通过将第一翘曲段211朝向第一开口11的外边缘倾斜设置，使得经第一开口11插入至壳体1内的电连接装置更容易与第一导电单元2接触，电连接装置被夹持的更紧，提高电连接装置与电连接器的连接强度，也即提高了电连接器在使用状态下的可靠性；并且由于第一翘曲段211是朝向第一开口11的外边缘倾斜设置的，因此，第一导电单元2的第一翘曲段211和第一连接段212的连接处与电连接装置的接触面积减少，即电连接装置的受力面积减小了，在使用过程中，对电连接装置的压力作用效果越强，对电连接装置夹的更紧，当电连接装置插入时，可缓解电连接装置插入的力，分散电连接装置插入的力，使其保持合适的插合力，也即，使得电连接装置更容易插入。
更进一步的，如图9所示，第一导电单元2还包括位于第二开口12的多个第二弹性臂24，多个第二弹性臂24沿垂直于第一电连接装置8或第二电连接装置9插入第二开口12的方向Q间隔设置，两两相邻的第二弹性臂24之间具有第二间隙25；其中，多个第二弹性臂24通过第一端子本体23与多个第一弹性臂21相连。
本申请通过将至少多个第二弹性臂24沿垂直于第一电连接装置8或第二电连接装置9插入第二开口12的方向Q间隔设置，不仅可以节省物料，降低生产制造成本；此外，由于物料减少了，故其与第二电连接装置9的接触面积减少了，因此还能有效降低接触的温升值(或可称温度阈值)和接触的电阻值。
在一个实施方式中，第二间隙25的宽度是第二弹性臂24的宽度的1％-100％。
为了验证相邻第二间隙25的间隔距离(宽度)对电连接器接触电阻的影响，选用 相同形状、尺寸的第一导电单元2和壳体1组成的电连接器，相同形状和尺寸的第一电连接装置8及第二电连接装置9，并将电连接器与第一电连接装置8连接，来观测第二电连接装置9与电连接器之间的接触电阻。
接触电阻的检测方式为使用微电阻测量仪，在第二电连接装置9与电连接器接触位置上进行电阻的测量，并读取微电阻测量仪上的数值，在本实施例中，接触电阻小于50μΩ为理想值。
表3：第二间隙25的间隔距离(宽度)对第二电连接装置9和电连接器结构之间接触电阻的影响
Figure PCTCN2022142643-appb-000003
从表3可以看出，第二间隙25的间隔距离(宽度)占第二弹性臂24的宽度的比值大于100％时，由于接触电阻大于50μΩ，不符合要求，另外电连接器结构现有的加工方式为冲压或者切割加工，第二间隙25的间隔距离(宽度)如果太窄，不容易加工，综上把第二间隙25间隔距离(宽度)定义为第二弹性臂24宽度的1％-100％。
进一步的，如图9所示，各第二弹性臂24包括自第二开口12至第一开口11依序连接的第二翘曲段241和第二连接段242，第二翘曲段241朝向第二开口12的外边缘倾斜设置。
通过将第二翘曲段241朝向第二开口12的外边缘倾斜设置，使得经第二开口12插入至壳体1内的电连接装置更容易与第一导电单元2接触，电连接装置被夹持的更紧，提高电连接装置与电连接器的连接强度，也即提高了电连接器在使用状态下的可靠性；并且由于第一翘曲段211是朝向第一开口11的外边缘倾斜设置的，因此，第一导电单元2与电连接装置的接触面积减少，即电连接装置的受力面积减小了，在使用过程中，对电连接装置的压力作用效果就越强，对电连接装置夹的更紧，当电连接装置插入时，可缓解电连接装置插入的力，分散电连接装置插入的力，使其保持合适的插合力，也即，使得电连接装置更容易插入。
在本实施方式中，如图9所示，第一导电单元2还包括呈条状的弹性臂连接件26，多个第二连接段242通过弹性臂连接件26连接在壳体1的内壁上。
通过将多个第二连接段242通过弹性臂连接件26连接在壳体1的内壁上，从而使得多个第二弹性臂24形成一个整体，进而提高各第二弹性臂24与壳体1连接的稳定性。
根据本申请的一个实施方式，如图7和图9所示，该电连接器还包括第二导电单元5，该第二导电单元5位于第一导电单元2与壳体1之间，第二导电单元5与第一导电单元2可拆卸地连接。通过设置第二导电单元5，提高电连接装置与电连接器的机械接触可靠性和电连接可靠性。
进一步的，如图8和图10所示，第二导电单元5上设有第一固定件6，第一导电单元2上设有第一固定配合件7，第一固定件6能与第一固定配合件7扣合连接。
本申请通过设置第一固定件6和第一固定配合件7，即可快速完成第一导电单元2和第二导电单元5的拆装，结构简单且连接牢固。
在本申请中，如图10所示，第二导电单元5包括位于第一开口11的第一弹性加强部51，第一弹性加强部51具有能沿壳体1的厚度方向H穿过第一间隙22多个凸出部511。
当壳体1内设有两个第一导电单元2时，第一弹性加强部51的多个凸出部511能沿壳体1的厚度方向H穿过第一间隙22而延伸至两个第一导电单元2之间，故当电连接装置经第一开口11或第一插入部13插入至壳体1内时，由于电连接装置的接触点增多了，可进一步提高其与电连接器的连接强度，也即，提高了电连接器在使用状态下与电连接装置连接的可靠性；另外，通过设置凸出部511，使其增大了第一导电单元2与电连接装置的接触面积，缩短电流传输距离，有效降低温升值(或可称温度阈值)和接触电阻值。
第一导电单元2和第二导电单元5的材质可以使用铜或铜合金材质，具体可以是碲铜合金、铍铜合金、磷青铜合金、铅黄铜合金或镍铜合金等。
碲铜合金具有良好的导电性和易切削性能，保证电学性能，也能提高加工性。
铍铜具有很高的硬度、弹性极限、疲劳极限和耐磨性，还具有良好的耐蚀性、导热性和导电性，且受冲击时不产生火花。
磷青铜优势是具备更好的耐蚀性、耐磨损，可保证接触良好，弹力好，并具有优良机械加工性能，可迅速缩短零件加工时间。
铅黄铜合金优势是强度高，组织致密均匀，耐蚀性好，切削、钻孔等机加工性能极佳。镍铜合金具有耐蚀性好、硬度高、延展性好的特点，能降低电阻率温度系数。
进一步的，如图10所示，第一弹性加强部51还包括正压部512，正压部512能沿 壳体1的厚度方向H与相邻的多个第一翘曲段211相抵接，多个凸出部511沿壳体1的宽度方向Q间隔设置在正压部512上。
通过设置正压部512，可以为各凸出部511提供安装基础，此外由于正压部512能沿壳体1的厚度方向H与相邻的多个第一翘曲段211相抵接，故当电连接装置经第一开口11、第一插入部13或第二插入部14插入至壳体1内而与第一导电单元2电性连接时，由于电连接装置具有一定的厚度，使得第一翘曲段211沿壳体1的厚度方向H朝靠近相邻的壳体1的内壁方向运动，故通过设置正压部512，可为第一翘曲段211提供正压力，使得第一导电单元2的第一翘曲段211不容易发生弯曲变形，提高第一导电单元2对电连接装置的夹持力。
如图10所示，第二导电单元5还包括位于第二开口12的第二弹性加强部53，第二弹性加强部53通过第二端子本体52与第一弹性加强部51相连，第二弹性加强部53具有沿壳体1的厚度方向H穿过第二间隙25多个加强臂531。
当壳体1内设有两个第一导电单元2时，第二弹性加强部53的多个加强臂531能沿壳体1的厚度方向H穿过第二间隙25而延伸至两个第一导电单元2之间，故当电连接装置经第二开口12插入至壳体1内的两个第一导电单元2之间时，由于电连接装置的接触点增多了，可进一步提高其与电连接器的连接强度，也即，提高了电连接器在使用状态下与电连接装置的连接的可靠性；另外，通过设置沿壳体1的厚度方向H穿过第二间隙25而延伸至两个第一导电单元2之间的多个加强臂531，使其增大了第一导电单元2与电连接装置的接触面积，缩短电流传输距离，有效降低温升值(或可称温度阈值)和接触电阻值。
进一步的，如图10所示，各加强臂531包括自第一开口11至第二开口12的方向依序连接的抵接段5311和接触段5312，多个抵接段5311能沿壳体1的厚度方向H抵接在第二弹性臂上，接触段5312沿壳体1的厚度方向H穿过第二间隙25。
通过设置抵接段5311，从而对第二连接段242提供正压力，当电连接装置经第二开口12插入至壳体1内而与第一导电单元2电性连接时，由于电连接装置具有一定的厚度，使得第二连接段242沿壳体1的厚度方向H朝靠近相邻的壳体1的内壁运动，故通过设置抵接段5311，可为第二连接段242提供正压力，使得第一导电单元2的第二连接段242不容易发生弯曲等变形，提高第一导电单元2对电连接装置的夹持力；通过设置接触段5312，以增多与电连接装置在第二开口12处的接触点，可进一步提高其与电连接器的连接强度，也即，提高了电连接器在使用状态下与电连接装置连接的可靠性，而 且还增大了与电连接装置的接触面积，缩短电流传输距离，有效降低温升值(或可称温度阈值)和接触电阻值。
上述实施例仅为了方便说明而举例而已，本申请所主张的权利范围应以权利要求的范围所述为准，而非仅限于上述实施例。
