Description

冠簧端子、电连接器插孔及电连接器 技术领域
本发明涉及电连接器，尤其涉及一种冠簧端子、使用该冠簧端子的电连接器插孔及电连接器。
背景技术
在电连接器技术领域中，有一类电连接器是在电连接器插孔内设置冠簧端子，通过使用冠簧端子来实现电连接器插孔与母端插针之间的导电连接。这类电连接器被广泛应用于电子及电器设备中。
现有技术的冠簧端子一般形成为圆筒状，在其两端的连接带之间设置有矩形的簧片。并且，在簧片的中部、朝向圆筒的内部轴心处形成凸起的接触点，通过这些接触点与外部插针电接触，来起到导通电路的作用。由于现有的冠簧端子中允许设置的接触点个数受到限制，接触电阻仍然较大，并且母端插针与电连接器插孔之间插拔力也较大，因此冠簧端子的现有结构已经无法满足大电流传输中对接触电阻和插拔力越来越高的要求。
此外，冠簧端子在簧片中部具有内径最小处，该最小处在多次插拔过程中易磨损且易降服，会导致插拔力不稳定，这种结构限制了冠簧端子的使用寿命。
因此，现有冠簧端子在导通能力、使用寿命等方面仍存在不足，无法满足高性能、高精度电器设备对接触面积大、导通能力强、寿命更长的要求。
发明内容
本发明是鉴于上述问题而完成的，其目的之一在于提供一种接触面积较大的高载流冠簧端子。
本发明的又一个目的在于提供一种寿命较长的高载流冠簧端子。

具体实施方式
以下通过具体实施方式来进行说明，本领域技术人员可由本说明书所公开的内容清楚地了解本发明的其他优点与技术效果。此外，本发明并不限于下述具体实施方式，也可通过其他不同的实施方式加以施行或应用，并且，对于本说明书中的各项具体内容，可在不背离本发明的精神下进行各种修改与变更。
下面，基于附图对本发明的具体实施方式进行详细叙述。所列举的附图仅为简单说明，并非依实际尺寸描绘，未反应出相关结构的实际尺寸，先予叙明。
图1是根据本发明一实施例的冠簧端子卷曲成筒状体时的立体图。图2是根据本发明一实施例的冠簧端子展平时的平面结构示意图，其中被显示的平面对应于图1所示筒状体的外表面，未被显示的平面对应于图1所示筒状体的内表面。
如图1和图2所示，在一些实施例中，冠簧端子100可以卷曲而形成筒状体，两端可以具有连接带，在两端的连接带之间可以包括多个简支梁101、102和多个悬臂梁103，在至少一对相邻的简支梁102与悬臂梁103之间，在其各自的中部处通过连接部104相互电气连接。通过采用这种设计，能够大幅缩减各简支梁与悬臂梁的宽度，从而可以在筒状体的圆周方向上尽可能多地设置简支梁与悬臂梁的个数，同时能够保持乃至可以增大与母端插针的接触面积。在一些实施例中，连接部104可以设置为偏离简支梁102和悬臂梁103的中部。
在另一些实施例中，在连接部104，在背离筒状体的轴心的方向上形成有凸起105，即在图2中向纸面外突出。从筒状体的内表面观察时，该凸起105也可以看成朝向该筒状体的外表面形成的凹陷。凸起105可以形成为球状凸起、也可以形成为矩形状等其他形状。凸起105的个数可以是一个，也可以是两个或更多个。现有技术中，利用设置于簧片上的朝向筒状体的轴心方向凸起的接触点与外部插针来进行电气连接。在这种结构下，冠簧端子的中部与外部插针的电接触形成为各个上述接触点与外部插针进行点接触。与之相反，本发明在连接部104上设置朝向背离筒状体的轴心的方向的凸起，即从筒状体的内表面观察时朝向外表面形成的凹陷。由此，关于冠簧端子的中部与外部插针的电接触，在一些实施例中，可以形成为该凹陷的至少一部分周边与外部插针进行多点接触。进一步地，在一些实施例中，还可以形成为该凹陷的整个周边与外部插针进行封闭环形接触，从而大幅增加了电接触面积，极大地提高了电气性能。
如图2所示，在一些实施例中，在该冠簧端子100中，可以形成有至少一个组合体。每个组合体可以由一个简支梁102和两个悬臂梁103构成。各简支梁102和悬臂梁103在其连接部104的位置可以被设置成朝向纸面内形成环带凹陷，以便在使用过程中提供与外部插针更好的电接触。通过采用这种独特的组合结构可进一步缩减各简支梁与悬臂梁的宽度，在有限的空间内最多地设置简支梁与悬臂梁，进而获得最多的接触部位和接触面积，得到最优的通流性能。在一些实施例中，可以在相邻的组合体之间设置至少一个附加的简支梁101和/或至少一个附加的悬臂梁，所述附加的简支梁和悬臂梁在环带凹陷部位与相邻的簧片电气隔离。在一些实施例中，在环带凹陷部位，也可以在组合体的连接部104、附加简支梁102和悬臂梁103上设置如现有技术那样的朝向筒状体的轴心的凸起，即在图2中向纸面内进一步凹陷。由此，即使采用现有技术那样的朝向筒状体的轴心的凸起，由于本发明上述特殊的组合体结构，简支梁和悬臂梁的数量大幅增加，因此凸起的个数可以相应地增加，从而增大了与母端插针的接触面积。
在一些实施例，简支梁101、102可以沿其自身延伸方向设置至少一段通孔。如图2所示，本实施方式中给出了在各个简支梁101、102形成三段通孔的示例，由此在简支梁中形成镂空结构。通过采用这种镂空结构，可以极大减少局部应力集中，减缓简支梁的局部塑性变形，从而延长冠簧端子的插拔寿命。在一些实施例中，可以沿至少一个简支梁设置一段或二段通孔。
在一些实施例，可以将悬臂梁103的两端中的至少一端形成为自由端，在图2所示的实施方式中，悬臂梁103设置为两端均为自由端的结构。可以将悬臂梁103的至少一个自由端形成为纺锤体结构。关于该纺锤体结构，可以将其设置为宽度从中央部向两侧逐渐变小且可以将该中央部形成为朝向纸面外凸起，从而增加了与后述的外套筒203的接触面积，可以实现与后述的外套筒203更为可靠的电接触。
进一步地，图3例示了对左侧冠簧端子100的A1部分进行放大而获得的悬臂梁的局部放大图。
在一些实施例中，如图3所示，将悬臂梁103的纺锤体结构103a的厚度设置为沿悬臂梁103的长度方向从纺锤体结构的中央部向自由端的端部逐渐变 薄。在一些实施例中，可以将纺锤体结构103a的中央部的内表面设置成突出于冠簧端子100的内表面，将自由端端部的内表面设置成与冠簧端子100的内表面齐平或缩进。在另一些实施例中，纺锤体结构103a可以具有沿悬臂梁103长度方向的通孔103b，该通孔103b可以形成为纺锤体状。通过采用这种纺锤体结构或者带通孔的纺锤体结构，可以大幅降低局部应力集中，减缓悬臂梁的局部塑性变形，提供更好的柔性和更长的插拔寿命。并且，通过如上述那样对纺锤体的厚度进行设计，从而能够避免外部插针插入时碰到自由端，避免了对冠簧端子造成损伤，极大提高了可靠性。在一些实施例中，如图2所示，在位于筒状体上下两端的连接带中，在与悬臂梁103的两端中的至少一端相对应的位置形成有至少一个凸起106。本实施方式示出了在与各个悬臂梁103的两端相对应的位置均形成一个凸起106的示例。同样地，该凸起106可以形成为球面状、也可以形成为矩形状等其他形状。通过设置凸起106，能够提供与后述的外套筒201更为可靠的接触。在另一些实施例中，也可以在与简支梁102的至少一端相对应的位置形成至少一个附加凸起。
在一些实施例中，可以将冠簧端子100形成为上下对称结构，从而无需区别装配方向，降低了装配难度和装配成本。
图4例示了使用根据本发明一实施例的冠簧端子的电连接器200。在一些实施例中，电连接器200包括电连接器插孔201和插针202，该电连接器插孔201可以包括外套筒203以及装配在外套筒203内的处于卷曲状态下的冠簧端子100，其中外套筒203的内表面具有与冠簧端子100的两端的连接带、以及冠簧端子100中所设置的悬臂梁的纺锤体中部电气连接的电连接部。插针202的外表面具有与冠簧端子100的中部所设置的连接部(例如，图2中的包含凸起105的部分)电气连接的电连接部。当插针202插入电连接器插孔201时，插针202的电连接部与位于冠簧端子100的中部环带处的包含上述凸起的连接部104进行电气连接，由于插针202与冠簧端子的电接触成为位于冠簧端子中部环带处的面接触，大幅增加了电接触面积，极大地提高了电气性能。通过使用具有上述结构的各种冠簧端子100，能够增大冠簧端子100与外套筒203和/或插针202的接触面积，获得更低的接触电阻，实现高载流传输。另一方面，通过使用具有上述结构的各种冠簧端子，由于大幅降低了因插拔而施加到电连 接器200的应力集中，从而可获得更为柔和的插拔力，极大提高了电连接器200的使用寿命。
以上详细描述了本发明的优选实施方式。但应当理解，在不脱离本发明的广义精神和范围的情况下可以采用各种实施方式及变形。本领域的普通技术人员无需创造性劳动就可以根据本发明的构思做出诸多修改和变化。因此，凡本领域技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应属于由本发明的权利要求书所确定的保护范围内。
