具体实施方式
为了使本领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都应当属于本发明保护的范围。
本发明提供一种转换插头、电源适配器加工方法及转换插头、电源适配器。 通过注塑的方式加工转换插头，简化了转换插头的结构，方便转换插头的携带，降低了成本。
本发明实施例提供一种转换插头加工方法，所述转换插头加工方法包括：
对PIN针的下部进行注塑，以形成包围所述PIN针下部的一个整体的注塑部；其中，所述注塑部包括与所述PIN针连通的插孔。
在一些实施例中，当多个转换插头对应同一个电源适配器本体时，为了保证多个转换插头能够适用同一个电源适配器本体，需要使得不同的PIN针注塑后形成的注塑部的插孔的规格(位置和大小等)一致。
由于采用上面的方法，通过注塑的方式加工转换插头，简化了转换插头的结构，方便转换插头的携带，降低了成本。另外，由于采用注塑的方式，转换插头整体成为一体结构，使得整个转换插头更加牢固；另外，可以减少PIN针底部暴露在外的风险，因此更加安全。
如图1所示，图1为本发明提供的对PIN针的下部进行注塑的方法的实施例的流程示意图。在一些实施例中，所述对PIN针的下部进行注塑包括如下方法步骤：
S11将PIN针放入第一注塑模具中进行第一次注塑形成位于所述PIN针的下部的第一注塑部，以定位所述PIN针；其中，所述第一注塑部包括与所述PIN针连通的插孔。
图2A-2D为多种安规下的PIN针的结构示意图。图3A-3D为完成第一次注塑后的多种安规下的转换插头的结构示意图。
如图2A-2D、图3A-3D所示，将各个PIN针11放入模具中，然后进行注塑，以形成位于所述PIN针11的下部的第一注塑部121，该第一注塑部121用于定位PIN针11(通常PIN针为2个或3个等等)的位置；并且形成与PIN针11连通的插孔13。
需要说明的是，各个国家对插头有不同的安规标准，比如：如图2A所示，为符合美国(UL)安规的转换插头；如图2B所示，为符合欧洲(EU)安 规的转换插头；如图2C所示，为符合英国(UK)安规的转换插头；如图2D所示，为符合澳大利亚(UL)安规的转换插头。
S12将所述第一注塑部放入第二注塑模具中进行第二次注塑形成第二注塑部，所述第二注塑部包括所述插孔。
如图4A-4D所示，图4A-4D为完成第二次注塑后的多种安规下的转换插头的结构示意图。
最终形成的第二注塑部122为包围PIN针11的下部和第一注塑部121的转换插头10最终的注塑部12。
该第二注塑部122包括第一次注塑后形成的插孔13。
图6A为本发明提供的电源适配器的转换插头和电源适配器本体分开后的结构示意图，其中，转换插头显示面对电源适配器本体部分的结构；图6B为本发明提供的电源适配器的转换插头和电源适配器本体分开后的结构示意图，其中，转换插头显示背对电源适配器本体部分的结构。
在一些实施例中，所述注塑部还包括第一定位部，所述第一定位部用于对装配后的转换插头和电源适配器本体之间进行定位，从而可以阻止组装后的二者因受到外力的作用发生分离，所述第一定位部与后面的第二定位部相配合，可以为各种将转换插头和电源适配器本体之间可拆卸的固定连接的结构组件，比如：卡接组件、螺钉和螺孔组件等等。
如图6A、6B所示，在一些实施例中，所述第一定位部包括用于与所述电源适配器本体20卡接的卡接组件中的第一卡接部141。
具体的，该第一卡接部141可以为用于卡接的任意结构组件中的其中之一，比如：卡槽和弹性卡扣141中的一个。
如图6A、6B所示，在一些实施例中,当将转换插头和电源适配器本体进行装配时，需要尽可能减少二者之间表面的接触，从而减少因为接触而产生的摩擦力，进而使得装配的过程更加顺滑和方便。
具体的，可以使得装配后的所述注塑部12对应电源适配器本体20的所述 插槽21的外表面的第一部分与所述插槽21的内表面的第二部分形成间隙，从而减少二者在装配的过程中，因为表面接触而产生的摩擦力。
具体的，在一些实施例中，可以设计将注塑部12至少沿侧向形成具有凸出部的端盖142，通过凸出部的下表面与插槽21顶面23摩擦接触进行限位，而其它面在装配过程中形成间隙，从而减少了摩擦的产生；或者设计将注塑部12的底部143与插槽21的底面接触，而其它面在装配过程中形成间隙等等；或者注塑部的端盖142和底部143都分别与插槽21对应摩擦接触，而侧面形成间隙等等。
在一些实施例中，所述第一部分为注塑部12的第一侧面(一个或者两个侧面)，所述第二部分为插槽的第二侧面(一个或者两个侧面)；为了使得注塑部的第一侧面和插槽第二侧面在装配后形成间隙配合，可以使得沿横向X的注塑部12的宽度略小于所述插槽内部的宽度，这样当进行装配的过程中，就可以使得二者之间存在间隙。
如图6A、6B所示，进一步，在一些实施例中，所述第一侧面(一个或者两个侧面)形成沿装配方向设置的导槽1412(一个或者两个导槽)；在所述插槽21的第二侧面对应所述导槽1412位置处沿横向X延伸形成与所述导槽1412配合的导条2112；当装配时，所述导条2112插入所述导槽1412，且二者之间相对面存在间隙，所以不会产生摩擦接触。需要说明的是，该导槽不限于设置在第一侧面，也可以设置在其它需要的方位。需要说明的是，所述导槽和导条的位置也可以互换。
进一步，在一些实施例中，当转换插头装配入插槽后，由于第一表面和第二表面之间存在间隙，因此，为了强化装配后这部分表面之间的连接强度，可以在导槽的末端(所述末端可以为最末端，也可以为靠近末端附近的位置)设置至少一个第一定位凸起1412A。所述末端是指在装配时，所述注塑部远离所述电源适配器本体的一端。这样当二者完成装配后，通过第一定位凸起1412A的限定，可以增加二者之间连接的强度。
后面实施例会对导槽和导条及第一定位凸起等等有进一步详细的说明。
如图2A-2D所示，在一些实施例中，由于不同国家的安规对PIN针规格要求的不同，可能有些PIN针之间的间距小，有些PIN针的间距大，为了使得这些符合不同安规的转换插头能够适用相同的电源适配器，因此，对于一些间距比较小或者比较大的PIN针，可以在所述PIN针11的下部形成向两侧延伸的弯折部111，从而减少或者增大两个PIN针之间的距离，从而使得多个转换插头可以共用同一个电源适配器本体。
具体的，当所述多个转换插头中的第一部分的转换插头的PIN针之间的距离小于与第二部分转换插头的PIN11针之间的距离时；所述第一部分的转换插头10的PIN针11的所述下部形成向彼此远离的两侧延伸的弯折部111；或所述第二部分的转换插头的PIN针的所述下部形成向彼此靠近的两侧延伸的弯折部。比如：AU或UL的PIN针11之间的间距相对其它国家的PIN针间距小，因此可以向彼此远离的两侧形成延伸的弯折部111。另一方面，也可以将PIN针之间的间距大于其他PIN针间距的转换插头的PIN针向彼此靠近的两侧形成延伸的弯折部(图未示意出)。
在一些实施例中，本发明还提供一种电源适配器加工方法，所述电源适配器加工方法包括上面任意一项所述转换插头加工方法。
有关转换插头的加工方法的相关描述参见上面的实施例，在此不再重复赘述。
图5为本发明提供的电源适配器的转换插头和电源适配器本体装配后的结构示意图。
如图1-6A、6B所示，在一些实施例中，本发明实施例还提供一种转换插头10，所述转换插头10包括PIN针11和包围所述PIN针的下部经过注塑形成的一个整体的注塑部12，所述注塑部12包括与所述PIN针11连通的插孔13。
由于采用上面的转换插头，通过注塑的方式加工转换插头，简化了转换插头的结构，方便转换插头的携带，降低了成本。另外，由于采用注塑的方式，使得转换插头整体成为一体结构，使得整个转换插头更加牢固；另外，可以减 少PIN针底部暴露在外的风险，因此更加安全。
如图7所示，在一些实施例中，所述第一定位部可以包括用于与所述电源适配器本体20卡接的卡接组件中的其中之一的第一卡接部141，在一些实施例中，第一卡接部141为弹性卡扣141。
如图2A-2D所示，在一些实施例中，当所述转换插头10包括多个，且所述多个转换插头10的PIN针11之间的距离彼此不等，所述多个转换插头10中的部分转化插头的PIN针的所述下部形成向两侧延伸的弯折部111。
如图6A、6B所示，在一些实施例中，本发明还提供一种电源适配器，所述电源适配器包括电源适配器本体20和转换插头10。
所述转换插头10包括PIN针11和包围所述PIN针的下部经过注塑形成的一个整体的注塑部12，所述注塑部12包括与所述PIN针11连通的插孔13。
所述电源适配器本体20包括形成容纳至少部分所述转换插头10的插槽21；所述电源适配器本体20包括一端位于所述插槽21内的导电弹片22，导电弹片22的另一端位于所述电源适配器本体20内，与内部电路电连接；当电源适配器本体20和转换插头10装配后，导电弹片22插入所述插孔13内与所述PIN针11贴合，从而可以实现电源适配器和转换插头之间的导电连通。
需要说明的是，所述插槽21的侧面对应转换插头的插入起始端为开口端24，这样转换插头10从开口端24沿插槽21插入直到插入插槽21的底部。
在一些实施例中，所述注塑部12还包括第一定位部；和/或所述电源适配器本体20还包括第二定位部；用于对装配后的所述转换插头和电源适配器本体之间进行定位，从而防止二者之间组装完成后二者之间受外力作用发生分离。
采用上面的电源适配器，通过注塑的方式加工转换插头，简化了转换插头的结构，方便转换插头的携带，降低了成本。另外，由于采用注塑的方式，使得转换插头整体成为一体结构，使得整个转换插头更加牢固；另外，可以减少PIN针底部暴露在外的风险，因此更加安全。
如图7所示，在一些实施例中，所述第一定位部包括用于与所述电源适配器本体20卡接的任意结构的卡接组件其中之一的第一卡接部141；则所述第二 定位部包括与所述第一卡接部141配合的用于卡接的任意结构组件中的另外一个的第二卡接部211。具体的，在本具体实施例中，第二卡接部211为卡槽211，第一卡接部141为弹性卡块141。通过第一定位部和第二定位部的配合进行定位。
如图8所示，在一些实施例中,当将转换插头和电源适配器本体进行装配时，需要尽可能减少二者之间的接触，从而减少二者之间因为接触而产生的摩擦。
具体的，可以使得装配后的所述注塑部对应所述插槽的外表面的第一部分与所述插槽的内表面的第二部分形成间隙，从而减少二者在装配的过程中，因为表面接触而产生的摩擦力。
如图6A、6B所述，具体的，在一些实施例中，可以设计将注塑部12至少沿侧向形成具有凸出部的端盖142，通过凸出部的下表面与插槽21的顶面23摩擦接触进行限位，而其它面在装配过程中形成间隙，从而减少了摩擦的产生；或者将注塑部12的底部143与插槽21的底面接触，而其它面在装配过程中形成间隙等等；或者端盖142和底部143都分别与电源适配器本体对应摩擦接触，而侧面形成间隙等等。
在一些实施例中，所述第一部分为注塑部的第一侧面(一个或者两个侧面)，所述第二部分为插槽的第二侧面(一个或者两个侧面)；为了使得注塑部的第一侧面和插槽第二侧面在装配后形成间隙配合，可以使得注塑部的横向X宽度略小于所述插槽内部的宽度，这样当进行装配的过程中，就可以使得二者之间存在间隙。
如图6A、6B所示，进一步，在一些实施例中，所述第一侧面(一个或者两个侧面)形成沿装配方向设置的导槽1412(一个或者两个导槽)；在所述插槽的第二侧面对应所述导槽位置处横向X延伸形成与所述导槽1412配合的导条2112；当装配时，所述导条插入所述导槽，且二者之间相对面存在间隙，所以不会产生摩擦接触。需要说明的是，该导槽不限于设置在侧面，也可以设置在其它需要的方位。
进一步，在一些实施例中，当转换插头装配入插槽后，由于第一表面和第 二表面之间存在间隙，因此，为了强化装配后这部分表面之间的连接强度，可以在导槽1412的末端(所述末端可以为最末端，也可以为靠近末端附近的位置)设置至少一个第一定位凸起1412A，该第一定位凸起即为第一定位部。所述末端是指在装配时，所述注塑部远离所述电源适配器本体的一端。这样当二者完成装配后，通过第一定位凸起1412A的限定，可以增加二者之间连接的强度；和/或
在另一些实施例中，可以在插槽21对应该部分的末端设置至少一个第二定位凸起2112A(所述末端是指在装配时，所述插槽远离所述转换插头的一端)，该第二定位凸起也即为第二定位部。这样当二者完成装配后，通过第二定位凸起的限定，可以增加二者之间连接的强度。
继续如图6A、6B所示，进一步，在一些实施例中，当形成转换插头和电源适配器本体分别形成导槽和导条结构时，导槽1412的第一末端设置第一定位凸起1412A,即第一定位部；所述导条2112的末端设置第二定位凸起2112A，即第二定位部；这样当完成转换插头10和电源适配器本体20装配后，通过第二定位凸起，进行定位。具体的，可以只设置第一定位凸起，也可以只设置第二定位凸起，或者即设置第一定位凸起，又设置第二定位凸起，通过二者的配合，使得定位更加牢固。
由于在第一末端设置第一定位结构和/或第二末端设置第二定位结构，这样，当二者之间在装配完成后，在定位结构处通过定位结构进行定位，这样由于导条和导槽之间存在间隙，从而使得装配过程更加顺滑的基础上；在将二者完全装配到位后，又通过定位结构进行定位，使得装配后的转换插头和电源适配器本体连接更加牢固；因此，通过简单的结构即实现了装配顺滑又使得装配后的二者连接更加牢固。
如图9所示，图9为本发明提供的电源适配器的插孔和导电弹片部分剖面的局部放大示意图。在一些实施例中，所述导电弹片22的位于所述电源适配器本体内的一端具有弹性部221，当转换插头和电源适配器本体相连接后，弹性部受作用力压缩变形，因此给电源适配器本体施加指向转换插头方向的作用力，以加固所述插孔与所述PIN针的贴合。所述弹性部可以为弹簧、弹片或弹性柱 塞等等现在开发及将来开发的具有类似功能的结构。
如图6A、6B所示，在一些实施例中，导电弹片22位于插槽21的侧面的开口端24相对的底部；则在一些实施例中，则对应的所述插孔13位于所述注塑部12的侧面，这样，转换插头10由侧面L方向插入插槽21内，可以减少装配过程中与导电弹片接触的机会，增加了装配过程中的安全性或可靠性。
有关转换插头的其它相关描述参见上面的转换插头加工方法中的描述，在此不再重复赘述。
