具体实施方式
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他实施例，都属于本发明保护的范围。
下面结合附图，对本发明的转接头、充电器和农业植保机进行详细说明。在不冲突的情况下，下述的实施例及实施方式中的特征可以相互组合。
实施例一
结合图1至图4，本发明实施例一提供一种转接头40，该转接头40可包括壳体1、正极插针2、负极插针3、信号插针4和控制电路5。其中，正极插针2、负极插针3和信号插针4并排设置设于壳体1的同一侧，本实施例的正极插针2、负极插针3和信号插针4用于与外部设备同时插接连接。控制电路5设于壳体1内，并且，控制电路5与正极插针2、负极插针3和信号插针4分别电连接。
在本实施例中，信号插针4包括多个，参见图4，多个信号插针4可包括第一信号插针41和第二信号插针42。其中，第一信号插针41与第二信号插针42间隔设置，且第一信号插针41的长度小于正极插针2、负极插针3以及除第一信号插针41外的其他信号插针4(包括第二信号插针42)的长度。待充电或供电的外部设备的对应位置设有与正极插针2、负极插针3和信号插针4对应的电插接孔，具体使用时，需将正极插针2、负极插针3和信号插针4与外部设备上的对应电插接孔插接连接。本实施例中，当第一信号插针41检测到外部设备与该第一信号插针41插接连接时，触发控制电路5控制转接头40输出电源而对外部设备进行供电或充电。需要说明的是，本发明实施例中，各插针(包括正极插针2、负极插针3和信号插针4)的长度是指各插针露在壳体1外部分的长度。
本发明实施例的转接头40，由于将第一信号插针41的长度设置成短于其他插针(包括正极插针2、负极插针3以及除第一信号插针41外的其他信号插针4)的长度，可确保外部设备与第一信号插针41插接连接时，外部设备与其他插针连接到位，从而确保了外部设备与转接头40接触面积够大，降低因接触面积过小而导致转接头40烧毁的风险；并且，通过第一信号插针41检测外部设备是否与该第一信号插针41插接连接来判断外部设备与转接头40是否插接到位，只有在第一信号插针41检测到外部设备与该第一信号插针41插接连接时，才会触发控制电路5控制转接头40输出 电源，确保了转接头40与外部设备连接到位时实现对外部设备的充电或供电，提高了充电或供电的安全性。
其中，外部设备可为需要进行充电的设备或结构，也可为需要进行供电的设备或结构。例如，在一实施例中，外部设备为无人机(如农业植保机)的电池，在对电池进行充电前，需要通过本实施例的转接头40连接电池以将电池接入充电器，从而通过充电器和外部电源的配合实现对电池的充电。本实施例中，转接头40可为充电器的一部分，也可与充电器分别独立设置。
在另一实施例中，外部设备为无人机(如农业植保机)的待供电结构(如电机、飞行控制器等)，本实施例的转接头40为电池的对外电接头，在对待供电结构供电前，将待供电结构插接在转接头40上，从而通过电池对待供电结构进行供电，使得待供电结构上电运行。
正极插针2、负极插针3和除第一信号插针41外的其他信号插针4的长度可根据需要设计，例如，在一实施例中，正极插针2、负极插针3与除第一信号插针41外的其他信号插针4的长度相等。在另一实施例中，正极插针2的长度与负极插针3的长度相等，除第一信号插针41外的其他信号插针4的长度稍小于正极插针2和负极插针3的长度，方便区分信号插针4与正极插针2、负极插针3。
本实施例的多个信号插针4中，每个信号插针4对应一种功能，如第一信号插针41用于检测外部设备与转接头40是否插针到位，第二信号插针42可用于传输外部设备和转接头40之间的数据信息等。
信号插针4的数量可根据功能需求的多少进行设计，又参见图4，本实施例中，多个信号插针4还包括第三信号插针43和第四信号插针44。当然，信号插针4并不限于4个，可根据功能需求对信号插针4的数量进行增减，本实施例对信号插针4的数量不作限制。
以信号插针4包括第一信号插针41、第二信号插针42、第三信号插针43和第四信号插针44为例对转接头40的结构进一步说明。
本实施例中，信号插针4的厚度较薄，为加固各信号插针4，防止插接造成的磨损。又参见图4，本实施例的第一信号插针41和第二信号插针42之间以及第三信号插针43和第四信号插针44之间分别设有绝缘体6，并且第一信号插针41和第二信号插针42分别连接在对应绝缘体6的两侧，第三信号插针43和第四信号插针44分别连接在对应绝缘体6的两侧。
各信号插针4和绝缘体6的连接方式可根据需要设计，例如，各信号插针4可通过粘接方式连接在对应的绝缘体6上，也可嵌设在对应的绝缘体6上，还可通过其他方式连接在对应的绝缘体6上。本实施例中，绝缘体6的两侧分别设有容纳槽，第一信号插针41、第二信号插针42、第三信号插针43以及第四信号插针44均嵌设在对 应容纳槽中。
绝缘体6的材质可根据需要选择为塑料或气体耐磨绝缘材质。
此外，本实施例的正极插针2、负极插针3和信号插针4的形状可根据需要设计，为方便与外部设备配合，本实施例的正极插针2、负极插针3和信号插针4的形状可设计成大致相同的形状。例如，在其中一实施例中，正极插针2、负极插针3和信号插针4均呈片状结构，增加了各插针与外部设备连接时的接触面。可选的，正极插针2、负极插针3和信号插针4的表面相互平行，方便插接外部设备，并且这种排布方式更加美观。当然，正极插针2、负极插针3和信号插针4的表面之间也可呈一定倾角，具体可根据需要设置正极插针2、负极插针3和信号插针4的表面之间的位置关系。
在另一实施例中，正极插针2、负极插针3和信号插针4均呈圆柱状或者其他规则形状，具体可根据需要设计正极插针2、负极插针3和信号插针4的形状。
可选的，第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的尺寸相等，一方面能够使得转接头40的结构更加美观，另一方面能够方便设计外部设备的电插接孔。以第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体、正极插针2以及负极插针3均为片状结构为例进行说明。本实施例中，第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的长度相等，且第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的厚度也相等。
当然，在另外一些例子中，第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的长度相等，而第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的厚度可设计成部分相等或各不相等。而在又一些例子中，第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的厚度也相等，而第一信号插针41、第二信号插针42及对应的绝缘体6形成的整体、第三信号插针43、第四信号插针44及对应的绝缘体6形成的整体与正极插针2、负极插针3的长度可部分相等或各不相等。
相关技术中，转接头40的正极插针2和负极插针3相邻设置，正极插针2和负极插针3距离过近容易发生打火现象，造成安全隐患。对于此，在本实施例中，正 极插针2和负极插针3分别设于多个信号插针4的两侧。具体的，多个信号插针4呈一排间隔设于正极插针2和负极插针3之间，将多个信号插针4居中设计，增大了正极插针2和负极插针3之间的距离，有效避免了正负极打火的风险。
此外，相关技术中，转接头40会容易因为正极插针2和负极插针3的冗余不足，导致正极插针2和负极插针3中的一个出现问题时，转接头40即无法使用。针对此，在本实施例中，参见图3，正极插针2包括多个，负极插针3与正极插针2对应，也包括多个，即负极插针3的个数与正极插针2的个数相同。其中，多个正极插针2呈一排间隔设置在信号插针4远离负极插针3的一侧，多个负极插针3呈一排间隔设置在信号插针4远离正极插针2的一侧。
可选的，正极插针2和负极插针3可为2个、3个、4个、5个或者更多，具体可根据需要设置正极插针2和负极插针3的冗余度。本实施例的转接头40包括3个正极插针2和3个负极插针3，使用正负极各3个插针的形式，增加了正负极的冗余度，只需1个正极插针2和1个负极插针3可使用，即可保证转接头40正常使用。在一实施例中，通过转接头40转接充电器和电池，电池充电最大可以通过电流为45A(单位：安培)，正负极单插针最大通过电流为60A。本实施例的正负极均为3个插针，只要保证正负极有各有1个插针可以工作，则可以正常给电池充电，相当于3倍冗余。
进一步的，结合图1和图3，转接头40还包括设于壳体1上的两个定位部7，其中一个定位部7设于正极插针2远离信号插针4一侧，并与正极插针2间隔设置，另一个定位部7设于负极插针3远离信号插针4一侧，并与负极插针3间隔设置。相应的，外部设备的对应位置设有与所述两个定位部7对应配合的两个定位配合部，在将外部设备插接在转接头40上时，两个定位部7与两个定位配合部连接而使外部设备与转接头40连接，使得各插针与对应的电插接孔稳定连接，外部设备和转接头40之间电源和信号能够稳定传输。定位部7与定位配合部之间的配合方式可选择现有固定连接方式，如定位部7与定位配合部可通过螺钉固定配合，也可插接配合。
可以理解的是，定位部7的数量、定位部7与各插针的位置关系并不限于上述所列举，还可以设置成其他形式，具体可根据需要设置定位部7的数量、定位部7与各插针的位置关系。
此外，又结合图1和图3，本实施例的转接头40还可包括设于壳体1上的限位部8，该限位部8包围形成一凹槽81，正极插针2、负极插针3和信号插针4位于凹槽81内，一方面凹槽81能够限制外部设备和转接头40的连接位置，外部设备能够更快速的与转接头40连接；另一方面凹槽81能够对各插针进行有效保护，防止在转接头40不使用时，各插针直接碰撞其他部件而损坏。可选的，在各插针的长度方向上，限位部8长于各插针的长度，从而对各插针形成有效保护。
随着充电器或电池的不断更新，充电器或电池的连接头50也不断更新，充电 器或电池更新前的连接头50无法与更新后的连接头50适配的外部设备适配，互通性较差。以充电器为例进行说明，将更新前的充电器称作1代充电器，更新后的充电器称作2代充电器，1代充电器的连接头50与2代充电器的连接头50不同，1代充电器可对第一型号的电池进行充电而无法对第二型号的电池进行充电，2代充电器可对第二型号的电池进行充电而无法对第一型号的电池进行充电，1代充电器和2代充电器之间的互通性较差。针对此，本实施例可在1代充电器的基础上，增加与1代充电器的连接头50配合的转接头40，该转接头40与第二型号的电池适配。在需要通过1代充电器对第一型号的电池进行充电时，直接将第一型号的电池连接在1代充电器的连接头50上即可；在需要通过1代充电器对第二型号的电池进行充电时，将转接头40与1代充电器的连接头50连接，再通过转接头40连接第二型号的电池，即可实现1代充电器对第二型号的电池充电的功能，无需分别购买1代充电器和2代充电器分别对两种型号的电池充电，降低了用户成本。
具体的，结合图3、图5以及图6，本实施例的转接头40还可包括适配部9，该适配部9用于可拆卸连接外部连接头50，其中，外部连接头50的型号与转接头40的型号不同。适配部9与控制电路5电连接，当外部转接头40与适配部9连接时，外部连接头50与转接头40电连接，提高了产品的兼容性。
本实施例中，壳体1包括前部和侧部，正极插针2、负极插针3和信号插针4设于前部，适配部9设于侧部，转接头40能够方便与外部连接头50和外部设备同时连接。当然，适配部9也可设置在壳体1的其他位置，并不限于侧部。
进一步的，侧部设有收容槽11，适配部9收容在收容槽11内，通过收容槽11对适配部9进行有效保护，并限制外部连接头50与适配部9之间的连接位置，使得外部连接头50与适配部9能够更快速地定位而连接。
结合图5和图6，本实施例的适配部9可包括正极适配端91、负极适配端92和信号适配端93，正极适配端91、负极适配端92和信号适配端93呈多排设置。相应的，外部连接头50的对应位置设有正极连接端、负极连接端和信号连接端，正极连接端与正极适配端91电配合，负极连接端与负极适配端92电配合，信号连接端与信号适配端93电配合，实现外部连接头50与转接头40之间的电连接。

正极适配端91、负极适配端92和信号适配端93的结构可根据需要设置，正极连接端与正极适配端91、负极连接端与负极适配端92以及信号连接端与信号适配端 93的结构相适配即可。例如，在一些例子中，正极适配端91、负极适配端92和信号适配端93均为电连接孔，正极连接端、负极连接端和信号连接端均为电插针。在另一些例子中，正极适配端91、负极适配端92和信号适配端93均为电插针，正极连接端、负极连接端和信号连接端均为电插孔。
进一步结合图5和图6，适配部9还可包括两个固定端94，正极适配端91、负极适配端92和信号适配端93设于两个固定端94之间。相应的，外部转接头40的对应位置设有与所述两个固定端94对应配合的两个固定配合端，在将外部连接头50与配合部连接时，两个固定端94与两个固定配合端连接而使外部连接头50与转接头40连接，使得正极适配端91与正极连接端、负极适配端92与负极连接端以及信号适配端93与信号连接端之间能够更加稳定连接，从而稳定传输电源和信号。固定端94与固定配合端之间的配合方式可选择现有固定连接方式，如固定端94与固定配合端可通过螺钉固定配合，也可插接配合。
可以理解的是，固定端94的数量、固定端94与各适配端(包括正极适配端91、负极适配端92和信号适配端93)的位置关系并不限于上述所列举，还可以设置成其他形式，具体可根据需要设置固定端94的数量、固定端94与各适配部9的位置关系。

连接头50可包括本体、正极连接端、负极连接端和信号连接端，正极连接端、负极连接端和信号连接端呈多排设置在本体上。本实施例中，连接头50包括1个正极连接端、1个负极连接端和2个信号连接端，1个正极连接端、1个负极连接端和2个信号连接端呈两排设置，并且相邻连接端之间间隔设置。当然，正极连接端、负极连接端和信号连接端之间的排布方式及正极连接端、负极连接端和信号连接端的数量也可设置成其他。
