Description

连接器公插头、连接器、无人飞行器及电池 技术领域
本发明涉及无人机技术领域，具体而言，涉及一种连接器公插头、一种连接器、一种无人飞行器及一种电池。
背景技术
现在的无人机，尤其是农业植保机及航模，多为大电流工况，在正常工作时电流会达到几十安培，且无人机电池的续航时间在几十分钟内，若长时间作业，需要有多组备用电池，电池通过连接器连接飞机或充电器时，均需要插拔连接器。现有连接器公插头具有柱状的插接部，插接部包括多个沿周向间隔设置且沿轴向延伸的弹性插片，使插头呈花瓣状结构，利用花瓣结构的弹性产生插拔力，但是花瓣状插头在经过多次插拔后就会产生变形，导致花瓣内收，从而连接器的插拔力大大减小，这样就会导致连接器的接触电阻增大，产生很大的热量，严重者就会导致连接器烧毁。
发明内容
有鉴于此，有必要提供一种能解决上述技术问题至少之一的连接器公插头。
本发明的第二个目的在于提供一种连接器。
本发明的第三个目的在于提供一种无人飞行器。
本发明的第四个目的在于提供一种电池。
为了实现上述目的，本发明第一方面的技术方案提供了一种连接器公插头，包括插头主体，所述插头主体具有柱状的插接部，所述插接部包括多个沿周向间隔设置且沿轴向延伸的弹性插片，各所述弹性插片共同围成安装孔，所述安装孔内设有弹性内芯，所述弹性内芯与各所述弹性插片抵接。
本发明第二方面的技术方案提供了一种连接器，包括基座和至少一个 上述任一技术方案中所述的连接器公插头，所述连接器公插头安装在所述基座上。
本发明第三方面的技术方案提供了一种无人飞行器，包括动力装置以及本发明第二方面任一技术方案中所述的连接器，通过所述连接器为所述动力装置供电。

与现有技术相比，本申请具有以下有益的技术效果：本技术方案在连接器公插头的弹性插片内侧安装弹性内芯，弹性内芯与各弹性插片抵接，起到支撑弹性插片的作用，连接器公插头与电池上或充电器上的母插头插接时，弹性插片因受母插头挤压而向内收拢，使得弹性内芯被压缩，连接器公插头拔出后，弹性插片在自身弹力及弹性内芯的弹力作用下回弹复位。增加弹性内芯有利于保持弹性插片的弹性，保证连接器公插头反复插拔后仍可保持原形，从而可有效解决连接器长时间使用后公插头变形的问题。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图4描述根据本发明一些实施例所述的连接器公插头、连接器、无人飞行器及电池。
本发明第一方面的技术方案提供了一种连接器公插头，如图2至图4所示，连接器公插头100包括插头主体110，插头主体110具有柱状的插接部，插接部包括多个沿周向间隔设置且沿轴向延伸的弹性插片111，各弹性插片111共同围成安装孔112，安装孔112内设有弹性内芯120，弹性内芯120与各弹性插片111抵接。
本方案提供的连接器公插头100，不需要改变插头主体110的结构，仅在弹性插片111围出的安装孔112内安装弹性内芯120，弹性内芯120与各弹性插片111抵接，起到支撑弹性插片111的作用，连接器公插头100与电池上或充电器上的母插头插接时，弹性插片111因受母插头挤压而向内收拢，使得弹性内芯120被压缩，连接器公插头100拔出后，弹性插片111在自身弹力及弹性内芯120的弹力作用下回弹复位。增加弹性内芯120有利于操持弹性插片111的弹性，保证连接器公插头100反复插拔后仍可保持原形，从而可有效解决连接器长时间使用后公插头变形的问题。
在上述实施例中，弹性内芯120由各弹性插片111夹紧固定。
本方案中，弹性内芯120通过弹性插片111夹紧固定，这样设计不需要在弹性内芯120间弹性插片111上加工出装配结构，弹性内芯120和弹性插片111的结构简单，生产加工难度低，有利于降低连接器公插头100的生产 成本，且弹性内芯120和弹性插片111装配操作简单有利于提升连接器公插头100的组装效率。
在上述实施例中，如图1至图4所示，弹性内芯120包括支撑体121以及设于支撑体121上的弹性部件，弹性部件与各弹性插片111抵接。
本方案中，弹性内芯120分为支撑体121和弹性部件两部分，这样每部分的结构简单，弹性部件设置在支撑体121上，弹性部件弹性支撑弹性插片111，以防止连接器公插头100多次插拔后变形。
其中，如图4所示，弹性部件包括多个弹性支撑筋122，多个弹性支撑筋122沿支撑体121的周向间隔设置。具体地，每个弹性支撑筋122沿支撑体121的径向向外突出弯曲，每个弹性插片111能够与至少一个弹性支撑筋122抵接。弹性内芯120还包括两个连接环123，各弹性支撑筋122的两端分别与两个连接环123相连接，连接环123套设在支撑体121上。
本方案中，弹性支撑筋122的两端通过连接环123安装到支撑体121上，弹性支撑筋122沿支撑体121的径向向外突出弯曲，且突出部位与弹性插片111抵接，弯曲的结构使得弹性支撑筋122具有良好的弹性，连接器公插头100与母插头插接时，弹性插片111向内收拢，将弹性支撑筋122向支撑体121压缩，连接器公插头100拔出后，弹性支撑筋122向支撑体121外侧回弹，推动弹性插片111回弹复位，从而防止连接器公插头100变形。
优选地，各弹性支撑筋122与两个连接环123一体成型；或/及，弹性支撑筋122为拱形。
本方案中，弹性支撑筋122与连接环123一体成型，这样设计省去了弹性支撑筋122与连接环123的装配工序，可提升连接器公插头100的装配效率，并且弹性支撑筋122与连接环123连接可靠性高，可避免弹性支撑筋122从连接环123上脱落，从而保证弹性支撑筋122与弹性插片111的配合效果。
在上述实施例中，弹性支撑体121为钣金件，各弹性支撑筋122通过冲裁弯曲成型，两个连接环123通过弯曲成型。
生产时，先通过冲裁使板材上形成支撑筋，然后通过弯曲使支撑筋呈弧形，以使支撑筋具有弹性，然后沿周向弯曲板材，使弹性支撑筋122两端形 成连接环123，并且通过弯曲工序将弹性部件套装到支撑体121上，这样弹性部件的生产工艺简单，且弹性部件与支撑体121的装配效率高。
可选地，支撑体121为金属柱状件。
这样设计支撑体121的结构强度高，支撑体121不易折断和磨损，因此连接器公插头100的使用寿命长。
其中优选地，支撑体121为铜柱。
在上述实施例中，优选地，弹性部件套设在支撑体121上。弹性部件绕支撑体121可转动。
在上述实施例中，支撑体121上沿周向设有环形限位槽，两个连接环123套装在环形限位槽内。
连接环123套装支撑体121上的环形限位槽内，环形限位槽对连接环123构成限位，可防止与弹性部件相接的连接环123从支撑体121上脱落。
在上述实施例中，安装孔112具有位于插接部的端面上的开口和与开口相对的底壁，支撑体121的一端与安装孔112的底壁抵接。
在上述实施例中，开口的口径小于弹性内芯120的横截面的最大尺寸，弹性内芯120能够通过挤压开口的周缘，使弹性插片111发生弹性形变，从而通过开口插入安装孔112内。
本方案令安装孔112开口的口径小于弹性内芯120的横截面的最大尺寸，这样设计弹性内芯120安装的可靠性高，弹性内芯120装入安装孔112后，不会从安装孔112的开口脱落。
在上述实施例中，如图3所示，插头主体110上沿周向设有环形安装槽113，环形安装槽113用于与连接器的基座配合。插头主体110安装到基座上时，基座与插头配合的部位卡入环形安装槽113内，对插头主体110构成限位，这样可提升插头主体110安装固定的可靠性，防止插头主体110从基座上脱落。
在上述实施例中，插头主体110为铜插头。
本发明第二方面的技术方案提供了一种连接器，如图1和图2所示，连 接器包括基座200和至少一个上述任一技术方案中所述的连接器公插头100，所述连接器公插头100安装在所述基座200上。
本发明第二方面实施例提供的连接器，具有本发明第一方面任一实施例提供的连接器公插头，因此该连接器具有上述任一实施例提供的连接器公插头的全部有益效果，在此不再赘述。
