上述结构中，每个插座01均需要单独安装于机箱03，则相邻的两个插座01之间预留有安装空间，导致光伏连接器占用机箱03的面积较大，使得整个机箱03较大。
另外，一个插头02设置有一个光伏线缆，每个插头02需要单独插拔，则相邻的两个插座01之间预留有插头02插拔所需的操作空间，而插头02插拔所需的操作空间较大，进一步加大了光伏连接器占用的面积，进一步加大了机箱03。

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。
如图2所示，本发明实施例提供的光伏连接器包括：插座100，以及用于和插座100插接的插头200。可以理解的是，插头200和插座100插接以实现插头200和插座100的电连接。
如图22所示，上述插座100用于设置在电气设备的机箱300上。为了便于维护，可选择上述插座100用于可拆卸地设置于机箱300。具体地，上述插座100用于通过紧固件可拆卸地设置于机箱300，上述插座100设置有供紧固件穿过的固定孔112。
上述插头200设置有至少一个光伏线缆240，该光伏线缆240用于和插座100电连接。
上述光伏连接器中，插座100用于和至少两个插头200插接；和/或，至少一个插头200的光伏线缆20至少为两个。
若插座100用于和至少两个插头200插接，即插座100对应至少两个插头200，较现有技术插座和插头一一对应相比，有效减小了插座100的数目，从而减小了插座100所需的安装面积，即减小了插座100占用机箱300的面积，进而减小了整个机箱300；同时，由于减小了插座100的数目，简化了光伏连接器的安装，提高了安装效率；由于减小了插座100的数目，降低了插座100的成本，从而降低了整个光伏连接器的成本。
若至少一个插头200的光伏线缆240至少为两个，较现有技术每个插头设置有一个光伏线缆相比，有效减小了插头200的数目以及需要预留的插头200插拔所需的操作空间，从而减小了光伏连接器所需的安装面积，即减小了光伏连接器占用机箱300的面积，进而减小了整个机箱300；同时，由于减小了插头200的数目，从而简化了光伏连接器的安装，提高了安装效率；由于减小了插头200的数目，降低了插头200的成本，从而降低了整个光伏连接器的成本。
因此，上述实施例提供的光伏连接器，减小了占用机箱300的面积，从而减小了整个机箱300；也简化了光伏连接器的安装，提高了安装效率；还降低了整个光伏连接器的成本。
上述光伏连接器中，若插座100用于和至少两个插头200插接，可选择至少两个插头200相同、和/或至少两个插头200不同。
需要说明的是，两个插头200相同，是指结构相同、大小相同。两个插头200不同，可选择两个插头200的结构不同和/或大小不同。具体地，若两个插头200的结构不同，可选择两个插头200的光伏线缆240不同。
可以理解的是，两个插头200的光伏线缆240不同，是指光伏线缆240的数目不同或光伏线缆240的极性不同。
为了便于制造和安装，若插座100用于和至少两个插头200插接，可选择至少两个插头200的光伏线缆240相同或至少两个插头200的光伏线缆240不同。
上述光伏连接器中，具有至少两个光伏线缆240的插头200中，可选择至少两个光伏线缆240的极性相同、和/或至少两个光伏线缆240的极性不同，根据实际需要选择。
具体地，若至少一个插头200的光伏线缆240至少为两个，至少一个插头200中至少两个光伏线缆240均为正极光伏线缆240a、和/或至少两个光伏线缆240均为负极光伏线缆240b、和/或至少一个光伏线缆240为正极光伏线缆240a且至少一个光伏线缆240为负极光伏线缆240b。
如图19所示，插座100用于和八插头200插接，八个插头200分别为：插头A200a、插头B200b、插头C200c、插头D200d、插头E200e、插头F200f、插头G200g、插头H200h。其中，任意两个插头200相同，每个插头200具有两个光伏线缆240，两个光伏线缆240分别为正极光伏线缆240a、负极光伏线缆240b。图19所示的光伏连接器安装于机箱300后，如图22所示。对比图1和图22，可知，在光伏线缆240相同的情况下，图22中光伏连接器所需的安装面积较小，即光伏连接器占用机箱300的面积较小。
如图20所示，插座100用于和四插头200插接，四个插头200分别为：插头A200a、插头B200b、插头C200c、插头D200d。其中，任意两个插头200相同，每个插头200具有四个光伏线缆240，四个光伏线缆240分别为两个正 极光伏线缆240a、两个负极光伏线缆240b。
如图21所示，插座100用于和六插头200插接，六个插头200分别为：插头A200a、插头B200b、插头C200c、插头D200d、插头E200e、插头F200f。其中，插头A200a具有一个正极光伏线缆240a；插头B200b具有一个负极光伏线缆240b；插头C200c和插头D200d相同且均具有一个正极光伏线缆240a和一个负极光伏线缆240b；插头E200e具有六个光伏线缆240，六个光伏线缆240分布为三个正极光伏线缆240a和三个负极光伏线缆240b；插头F200f具有四个光伏线缆240，四个光伏线缆240分布为两个正极光伏线缆240a和两个负极光伏线缆240b。
在实际应用过程中，还可选择插头200的类型以及分布为其他，并不局限于图19-21所示的三个实施方式。
上述光伏连接器中，对于插头200和插座100的具体结构，根据实际需要选择。
可选地，如图6-10所示，上述插头200包括：插头壳210和设置于插头壳210内的插针230，插头壳210用于插接在插座100内，插针230的一端和光伏线缆240电连接且固定连接，插针230的另一端用于和插座100电连接，插针230和插头壳210绝缘连接。
上述结构中，通过设置插针230，方便了光伏线缆240和插座100电连接；通过设置插头壳210，方便了插头200和插座100插接。
为了便于连接光伏线缆240和插针230，可选择插针230压合于光伏线缆240。这样，通过压合同时实现了固定连接和电连接。
在实际应用中，也可选择光伏线缆240和插针230通过其他方式实现电连接以及固定连接，并不局限于上述实施方式。
上述光伏连接器中，为了便于插针230和插座100电连接，上述插针230用于和插座100的导电件120套设连接且电连接。
具体地，可选择插针230用于外套于导电件120，也可选择导电件120用于外套于插针230。为了提高稳定性，可选择插针230和导电件120通过套设 配合实现固定连接。例如，插针230和导电件120过渡配合或过盈配合，本实施例对此不做限定。
为了提高可靠性，可选择光伏线缆240和插头壳210密封连接。对于密封连接的方式，根据实际需要选择，本实施例对此不做限定。
上述光伏连接器中，插针230和插头壳210绝缘连接，可选择插针230和插头壳210直接绝缘连接，具体地，可选择插头壳210为绝缘件。当然，也可选择插针230和插头壳210间接绝缘连接，具体地，插针230和插头壳210通过绝缘件间接绝缘连接。
为了便于安装插针230，上述插头200还包括固定于插头壳210内的插芯220，该插芯220具有安装孔222，插针230位于安装孔222内，且插针230和插芯220沿插针230的轴向限位配合。
上述结构中，插芯220连接插头壳210和插针230。此结构中，可选择插芯220为绝缘件，这样，实现了插针230和插头壳210绝缘连接。
上述插头200中，整个插针230位于安装孔222内或插针230伸出安装孔222，根据实际需要选择。为了便于安装，可选择整个插针230位于安装孔222内。此时，若插针230用于和导电件120套设连接且电连接，可选择导电件120用于伸入安装孔222内并内套于插针230。具体地，插针230设置有插接孔232，导电件120伸至插针230的插接孔232内。
为了便于轴向限位，如图11和图13所示，上述插针230和插芯220中，一者设置有限位凸起223、另一设置有与限位凸起223配合的限位凹槽231。为了便于安装以及提高稳定性，可选择限位凸起223设置于插芯220，限位凹槽231设置于插针230。
对于限位凸起223和限位凹槽231的形状、数目和大小，根据实际需要选择。为了简化结构，可选择上述限位凸起223和限位凹槽231均呈环形，且均沿其所在部件的周向设置。
为了安装和拆卸，上述插芯220和插头壳210可拆卸地固定连接。具体地，插芯220卡接于插头壳210，即插芯220和插头壳210通过卡接实现可拆卸地 固定连接。
如图8、图11-13所示，上述插芯220和插头壳210中，一者设置有第一卡扣221、另一者设置有与第一卡扣221卡接的第一卡槽212。为了便于安装，可选择第一卡扣221设置于插芯220，第一卡槽212设置于插头壳210。
对于第一卡扣221和第一卡槽212的结构、大小和数目，根据实际需要选择。为了简化结构以及保证稳定性，可选择第一卡扣221和第一卡槽212均为两个，且均位于其所在部件的两端。
若上述插头200包括插头壳210、插芯220和插针230，为了提高安全性，光伏线缆240和插头壳210密封连接以及光伏线缆240和插芯220密封连接。可选地，上述插头壳210和插芯220均通过线缆密封件250和光伏线缆240密封连接，其中，插头壳210设置有与线缆密封件250卡接的卡孔213，线缆密封件250位于安装孔222内。可以理解的是，线缆密封件250位于插头壳210和插芯220之间。
为了便于安装，上述安装孔222靠近卡孔213的一端具有和线缆密封件250配合的渐扩孔2221，且渐扩孔2221自其远离卡孔213的一端至其靠近卡孔213的一端渐扩。
上述插头200的安装方法为：如图11所示，将线缆密封件250安装在插头壳210的卡孔213中，光伏线缆240和插针230形成的线缆组件穿过线缆密封件250，插针230上的限位凹槽231卡于插芯220上的限位凸起223实现轴向限位，自然条件下不借助外力或工具，线缆组件与插芯220均不会松脱；如图12所示，向靠近线缆密封件250的一侧推动带有线缆组件的插芯220，即沿图12所示的箭头方向推动带有线缆组件的插芯220，听到“卡塔”声，插芯220的第一卡扣221弹入插头壳210的第一卡槽212内，同时压紧线缆密封件250，如图8所示，这样既实现了光伏线缆240与插头壳210之间的密封，又增大了光伏线缆240的拉拔力。
在实际应用中，也可选择在安装过程中，先将线缆密封件250安装在插芯220的安装孔222内，具体地，先将线缆密封件250安装在渐扩孔2221内， 如图13所示。其他步骤如上所述，此处不再赘述。

对于第二卡扣211和第二卡槽113的结构、大小和数目，根据实际需要选择。为了简化结构以及保证稳定性，可选择第二卡扣211和第二卡槽113均为两个且分别位于其所在部件的两端。
上述光伏连接器中，光伏线缆240用于插座100可拆卸地电连接，以实现插头200用于和插座100可拆卸地电连接。若插头200包括插针230和插芯220，则插针230用于和插座100可拆卸地电连接。

对于上述分隔件130的数目，根据导电件120的数目进行设置，本实施例对此不做限定。
上述插座100中，导电件120可完全位于插槽111内，也可伸出插槽111。为了便于插座100和机箱300内的器件连接，上述导电件120的一端位于插槽111内，且导电件120的另一端自插槽111的底端伸出插槽111。
为了提高安全可靠性，上述插头200用于和插座100密封连接。可选地，插头200用于通过插头密封件140和插座100密封连接。
一方面，可选择上述插头密封件140设置于插槽111的槽底壁或槽侧壁。此时，插头密封件140和插头100结合在一起，在安装过程中，先将插头密封件140和插槽111组装在一起，再安装插头200。如图3、图4和图15所示，上述插头密封件140设置于插槽111的槽底壁，此情况下安装完插头200和插座100后插头密封件140和插头200的端面抵接；如图18所示，上述插头密封件140设置于插槽111的槽侧壁，此情况下安装完插头200和插座100后插头密封件140和插头200的侧面抵接。
