具体实施方式
以下结合附图对本申请的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。
本申请实施例提供的电连接器，用于将多个被连接件电连接。例如，如图1所示，被连接件为PCB板，且为两个，分别为第一PCB板3a和第二PCB板3b，电连接器用于将第一PCB板3a和第二PCB板3b电连接。
电连接器包括绝缘壳体结构1和电接触件2(如图3A所示)，其中，绝缘壳体结构1采用绝缘材料制作，例如塑胶材料。并且，在本实施例中，如图2A所示，绝缘壳体结构1包括可拆卸连接的壳体底座11和盖板12，其中，壳体底座11用于与第一PCB板3a和第二PCB板3b固定连接，并且壳体底座11中具有能够容纳电接触件2的容纳槽；盖板12用于封闭壳体底座11中的容纳槽的开口，上述第一PCB板3a和第二PCB板3b相互平行，且位于同一平面内，并安装在盖板12的与容纳槽相反的一侧。并且，在盖板12的板面上设置有多个开口121，如图2A所示，电接触件2的多个触点部22分别经由多个开口121延伸至绝缘壳体结构1的外部，以能够与第一PCB板3a或第二PCB板3b电接触。
通过借助上述绝缘壳体结构1将电接触件2容纳在其中，不仅可以减小占用空间、简化设备结构，而且有利于装配和实现模块化。
需要说明的是，在本实施例中，为了实现平行、共面的第一PCB板3a和第二PCB板3b的电连接，多个开口121均位于盖板12的板面上(并贯穿盖板12)，但是，本申请实施例并不局限于此，在实际应用中，根据具体需要，可以将各个开口121设置在绝缘壳体结构1的壳体上的位置，例如，至少一个开口121还可以设置在壳体底座11上。
还需要说明的是，在本实施例中，绝缘壳体结构1由壳体底座11和盖板12构成，但是，本申请实施例并不局限于此，在实际应用中，绝缘壳体结构1也可 以由其他任意结构的至少两个分体构成，或者绝缘壳体结构1还可以采用整体式结构，并结合公知技术手段将上述电接触件2预埋在绝缘壳体结构1的空腔中。
如图3A所示，电接触件2包括多个导电条2a，多个导电条2a间隔排列在绝缘壳体结构1中；如图3B所示，每个导电条2a的主体21设置在上述绝缘壳体结构1中，且每个导电条2a的主体21包括中间段211和位于该中间段211两侧的两个边缘段(212a，212b)，其中，中间段211被设置为能够支撑两个边缘段(212a，212b)的支撑部；两个边缘段(212a，212b)相对于中间段211，朝靠近彼此的方向弯折，以分别构成与中间段211相连的第一弯折部，并且两个边缘段(212a，212b)的远离中间段211的一端分别形成有触点部(22a，22b)。
在本实施例中，两个触点部(22a，22b)均为导电条2a的一部分，且分别相对于两个边缘段(212a，212b)弯折，以分别构成第二弯折部。如图2A所示，该第二弯折部的末端位于绝缘壳体结构1的内部。这样，可以使触点部22通过位于其两端之间的弯折区域与PCB板电接触，与通过触点部22的末端与PCB板电接触的情况相比，接触面积更大，从而可以提高接触可靠性。
借助中间段211支撑两个边缘段(212a，212b)，可以使两个触点部(22a，22b)的至少弯折区域能够保持在绝缘壳体结构1外部的位置，同时通过使两个边缘段(212a，212b)相对于中间段211朝靠近彼此的方向弯折，可以使整个导电条2a具有弹性。具体来说，在将PCB板压向盖板12时，导电条2a的两个边缘段(212a，212b)相对于中间段211产生弹性变形，从而使各个触点部22会向相应的PCB板施加与其压力相反的弹力，即实现使两个触点部(22a，22b)均能够与相应的PCB板弹性接触。这种弹性接触可以增大电连接器与PCB板之间的接触配合容差(垂直于盖板12的板面方向，且容差可达±1mm)，减小安装误差，提高安装效率。
在本实施例中，以将平行、共面的第一PCB板3a和第二PCB板3b电连接为例，多个开口121在盖板12的板面上排布形成两列开口组，两列开口组分别与第一PCB板3a和第二PCB板3b相对设置。并且，其中一列开口组中的各个开口121与其中另一列开口组中的各个开口121一一对应地排成一行；导电条2a的数量与开口排布的行数相同，且各个导电条2a的两个触点部(22a，22b)与各行中的两个开口121一一对应设置。这样，每个导电条2a的两个触点部(22a，22b)均用于分别与第一PCB板3a和第二PCB板3b电接触，以实现第一PCB板3a和第二PCB板3b的电连接。
在实际应用中，在每个PCB板上设置有导电层，用于同时与同一列开口组中的至少一个开口121所对应的触点部22电接触，该导电层例如为铜箔层。当然，如果PCB板的某个触点不希望与相应PCB的对应触点电连接，则例如与该触点对应的位置可不设置导电层或可在导电层外设置绝缘层。
通过设置多个导电条2a，可以增大电连接器与PCB板之间的接触配合容差(平行于盖板12的板面的方向，且容差可达±1mm)，减小安装误差，提高安装效率。 另外，在一些实施方式中，每个导电条2a可以产生一定程度的塑性变形，这使得两个边缘段(212a，212b)与中间段211之间的夹角a(见图3B)的大小可调，从而可以调节触点部22伸出绝缘壳体结构1的最大距离，以获得合适的接触作用力，达到在保证导电条2a不发生过大的塑性变形的前提下，增大电连接器与PCB板之间的接触配合容差(垂直于盖板12的板面方向，且容差可达±1mm)的目的。例如，可以通过调节夹角a的大小，使得上述最大距离为3mm。
需要说明的是，在本实施例中，电接触件2包括多个导电条2a，但是，本申请实施例并不局限于此，在实际应用中，电接触件2还可以采用其他任意结构。例如，电接触件2为整体式结构，例如是与上述导电条2a的结构相类似的单个导电片(宽度例如是所有导电条2a的宽度之和)。
另外，上述导电条2a适用于平行、共面的第一PCB板3a和第二PCB板3b的电连接，在实际应用中，随着PCB板的布局方式的变化，或者被连接件为除PCB板之外的部件，也可以适应性改变电接触件2的结构，凡是电接触件2具备如下结构和功能，就可以实现本申请实施例的目的：电接触件2包括设置在绝缘壳体结构1中的主体和在该主体上形成的多个触点部，电接触件2具有弹性，以使各个触点部22能够与相应的被连接件弹性接触。这样，无需再采用诸如具有公母两端的连接结构，免于焊接和插接，从而可以实现快速连接。此外，由于电接触件2具有弹性，以使各个触点部能够一一对应地与各个被连接件弹性接触，这可以增大电连接器与被连接件之间的接触配合容差，减小安装误差，提高安装效率。
还需要说明的是，在本实施例中，导电条2a的中间段211被设置为能够支撑两个边缘段(212a，212b)的支撑部；两个边缘段(212a，212b)分别构成第一弯折部，但是，本申请实施例并不局限于此，在实际应用中，可以根据具体情况设计上述支撑部的结构，以及相对于该支撑部弯折的第一弯折部的结构和弯折方向，此外，每个第一弯折部的远离支撑部的一端形成有上述触点部。
在本实施例中，如图4所示，在壳体底座11的内侧表面(例如，容纳槽的底面)上设置有第一限位结构，该第一限位结构用于限定电接触件2的位置。例如，第一限位结构包括在壳体底座11的内侧表面上形成的第一限位槽和插接件；对应地，在电接触件2的主体上形成有与上述第一限位槽相配合的限位部，和与上述插接件插接的插接槽。如图4所示，第一限位槽例如由间隔设置的第一凸块111a和第一凸块111b限定而成；插接件例如由设置在该第一限位槽两侧的第二凸块112a和第二凸块112b组成；对应地，如图3B所示，导电条2a的主体21的一部分(例如中间段211)位于第一限位槽中，且在导电条2a的主体21的两侧分别设置有两个限位凸块24，主体21的每一侧的两个限位凸块24用于将与二者同侧的第一凸块限定在两个限位凸块24之间，从而可以限制导电条2a沿第一限位槽移动。并且，在导电条2a的两个边缘段(212a，212b)上均设置有插接槽23，用于分别与第二凸块112a和第二凸块112b插接，从而可以限制导电条2a转动。
在本实施例中，如图5所示，在盖板12的内侧表面(背离盖板12的正面122)设置有第二限位结构，该第二限位结构用于限定电接触件2的位置。例如，第二限位部包括在盖板12的内侧表面上形成的第二限位槽124，电接触件2的主体的一部分位于该第二限位槽124中。例如，导电条2a的两个边缘段(212a，212b)的远离中间段的部分位于该第二限位槽124中。
借助上述第一限位结构和第二限位结构，可以避免导电条2a在单边接触(即，只有一个边缘段上的触点部接触PCB板)时发生单板翘曲的情况，从而可以在两个PCB板存在高度差时，仍然可以保证信号的有效传递。当然，在实际应用中，还可以采用其他任意结构的第一限位结构和第二限位结构，只要能够限定电接触件2的位置即可。
在本实施例中，在盖板12的周向侧面间隔设置有多个卡接件。如图5所示，对于矩形盖板12，在其长边侧面设置有四个宽度较小的卡接件125a，且在短边侧面设置有一个宽度较大的卡接件125b。如图6所示，卡接件125a和卡接件125b例如为楔形块，该楔形块相对于盖板12的周向侧面凸出的高度越靠近盖板12的板面内侧越小。
对应地，如图4所示，在壳体底座11的内侧面设置有多个卡槽113，各个上述卡接件一一对应与各个卡槽113卡接，卡接方式如图6所示。当盖板12压入壳体底座11时，上述楔形块的坡面沿壳体底座11的内侧面移动，直至楔形块移入上述卡槽113，此时楔形块的垂直面与卡槽113的侧面相配合，使得盖板12难以与壳体底座11分离。
上述楔形块和卡槽的卡接方式不仅有利于降低壳体底座11和盖板12的制造难度，而且结构简单，固定可靠。
在本实施例中，如图7A所示，在壳体底座11的背离盖板12的一侧(即，壳体底座11的背面114)设置有两个安装孔(115a，115b)和两个定位件(116a，116b)，两个安装孔(115a，115b)和两个定位件(116a，116b)呈矩形排列，例如，对于近似于矩形的壳体底座11，两个安装孔(115a，115b)和两个定位件(116a，116b)排布在该壳体底座11的四个边角处。其中，两个安装孔(115a，115b)呈对角设置，每个安装孔用于通过紧固件(例如螺钉或螺栓)与PCB板固定连接；两个定位件(116a，116b)呈对角设置，每个定位件用于通过与设置在PCB板上的定位结构相配合，以限定壳体底座11的位置和方向，该定位件例如为定位柱体，PCB板上的定位结构例如为与该定位柱体相配合的定位槽。
通过使两个定位件(116a，116b)呈对角设置，可以快速定位壳体底座11的摆放位置和方向，从而可以有效解决连接器装反问题以及摆放位置不对需重新摆放，造成效率低的问题。
在本实施例中，如图7A和图7B所示，在壳体底座11的两个安装孔(115a，115b)所在的侧面分别设置有凸台117a和凸台117b，如图7B所示，凸台117a和凸台117b使在壳体底座11的背面114的轮廓近似为倒“S”型，这可以进一 步避免连接器装反，从而可以提高安装效率。
综上所述，本申请实施例提供的电连接器，其通过借助绝缘壳体结构将电接触件容纳在其中，不仅可以减小占用空间、简化设备结构，而且有利于装配和实现模块化；并且，通过在电接触件的主体上形成有多个触点部，各个触点部一一对应地穿过各个开口，并延伸至绝缘壳体结构的外部，各个被连接件仅需接触各个触点部即可实现电连接，而无需再采用诸如具有公母两端的连接结构，免于焊接和插接，从而可以实现快速连接。此外，由于电接触件具有弹性，以使各个触点部能够一一对应地与各个被连接件弹性接触，这可以增大电连接器与被连接件之间的接触配合容差，减小安装误差，提高安装效率。
作为另一个技术方案，本申请实施例还提供一种电子设备，包括多个被连接件，以及本申请实施例提供的上述电连接器，该电连接器用于将多个被连接件电连接。
上述被连接件例如包括印制电路板(PCB板)。PCB板的用于与电连接器配合的可选结构已在上文中描述，在此不再赘述。
本申请实施例提供的电子设备，其通过采用本申请实施例提供的上述电连接器，不仅可以减小占用空间、简化设备结构，而且有利于装配和实现模块化；还可以实现快速连接、增大电连接器与被连接件之间的接触配合容差，减小安装误差，提高安装效率。
可以理解的是，以上实施方式仅仅是为了说明本申请的原理而采用的示例性实施方式，然而本申请并不局限于此。对于本领域内的普通技术人员而言，在不脱离本申请的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本申请的保护范围。
