在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
如图1至图5所示，本实施例提供一种连接器，可以应用于两轮的电动车。该连接器包括座体1、连接组件2、第一端子组件3、第二端子组件4和第三端子组件5。
其中，第一端子组件3、第二端子组件4和第三端子组件5均设置于座体1上，第一端子组件3被配置为与充电端口连接，第二端子组件4被配置为与待供电端口连接，第三端子组件5被配置为与通讯端口连接。连接组件2包括插拔端子21，第一端子组件3与电池包之间、第二端子组件4与电池包之间以及第三端子组件5与电池包之间均通过插拔端子21连接。
参阅图1，当需要给电池充电时，将充电端口与第一端子组件3连接即可实现充电。当电池包需要给车体供电时，将车体上的待供电端口和通讯端口分别与第二端子组件4和第三端子组件5连接即可为车体供电、以及实现通讯连接。即，通过将第一端子组件3、第二端子组件4和第三端子组件5均设置在座体1上，使得该连接器既可以实现充电端口与电池包的连接，又可以实现待供电端口以及通讯端口与电池包的连接。因此，只需在电池包的外壳上安装一个连接器即可实现电池包的充电、放电、通讯等功能，并且只需在电池包的外壳上开 设一个安装孔即可满足连接器的安装需求，相比于相关技术中在外壳上为每个不同功能的连接器均开设安装孔的方法，该连接器的设置方式能够节省电池包的开模成本，同时缩短产品生产周期。
相关技术中，由于需要在电池包的外壳上安装多个连接器后，因此每个连接器均需配备密封圈，多种连接器的设置增加了密封圈数量，导致密封圈失效的风险增加，从而使电池包进水的风险增大。本实施例中，由于连接器的安装数量减少，使得密封圈的使用数量减少，因此电池包进水的风险也大大降低，能够提高电池的使用可靠性和安全性。并且，在后期电池包需要更换连接器时，只需更换一个连接器即可，降低了电池包的维护成本。
此外，由于相关技术中的连接器与电池包的电池模组之间需要通过导线连接，因此在更换连接器时需要拆开电池包的外壳，以连接导线，导致连接器的更换效率低。本实施例中，通过设置插拔端子21，在后期更换连接器时，只需将电池包电池模组的插接端直接与对应的插拔端子21连接即可，无需拆开电池包的外壳，连接器更换速度快，电池包的维护难度降低，同时进一步降低了电池包的维护成本。
示例性的，参阅图1，座体1上设置有第一凹槽11和第二凹槽12，第一端子组件3设置于第一凹槽11内，第二端子组件4和第三端子组件5均设置于第二凹槽12内。第一凹槽11和第二凹槽12的设计，能够使第一端子组件3、第二端子组件4和第三端子组件5均嵌设在连接器底座内，以防止第一端子组件3、第二端子组件4和第三端子组件5因碰撞而损坏。同时第一凹槽11和第二凹槽12的设置能够使连接器安装至电池包的外壳上后与外壳保持齐平，提高了电池包的美观度。
示例性的，参阅图1和图3，第一端子组件3包括正极充电端子31、负极充电端子32和接地端子33。参阅图2和图12，连接组件2还包括正极充电导线22、负极充电导线23和接地导线29，正极充电导线22的一端与正极充电端子31连接，另一端与对应的插拔端子21连接，负极充电导线23的一端与负极充电端子32连接，另一端与对应的插拔端子21连接，接地导线29与接地端子33连接。电池包内部的电池模组上引出有插接端，插接端位于电池包外壳的安装孔内，安装连接器时，将正极充电导线22的插拔端子21与对应的电池包正极导线的插接端插接，负极充电导线23的插拔端子21与对应的电池包负极导线的插接端插接，即可完成连接器的安装。该插接连接的安装方式无需拆开电池包的外壳即可完成连接器与电池包的连接，连接器安装效率高。当需要给电池包充电时，充电端口内的火线、零线和接地线分别与正极充电端子31、负极充电端子32和接地端子33接触连接，以实现电导通，从而向电池包内充电。接地端子33的设置使得电池包充电时能够接地，起到漏电保护作用，防止充电过程中因意外漏电而发生触电事故。
示例性的，参阅图1，第一凹槽11内设有凸起的第一凸台111，第一凸台111上设置有三个第一插接孔1111，正极充电端子31、负极充电端子32和接地 端子33分别设置于对应的第一插接孔1111内。本实施例中，参阅图2和图3，给出的是第一种连接器的正极充电端子31、负极充电端子32和接地端子33的结构类型，三者分别为设置在第一插接孔1111内壁上的金属片。相应的，充电端口上设置三个金属插脚，当电池包需要充电时，将三个金属插脚分别对应插入三个第一插接孔1111内，以使金属插脚与金属片接触连接，即可使正极充电端子31、负极充电端子32和接地端子33与充电端口电连接，实现电池包充电。
在另一个示例的实施例中，正极充电端子31、负极充电端子32和接地端子33也可均为金属插脚，金属插脚凸起设置于第一凹槽11的底壁上。如图6、图7、图8和图9所示，给出的分别是第二种连接器和第三种连接器的正极充电端子31、负极充电端子32和接地端子33的结构类型，三者均为金属插脚。相应的，充电端口上设置有三个插口，每个插口内均设置有金属接触点，当充电端口插入第一凹槽11后，正极充电端子31、负极充电端子32和接地端子33分别插入对应的插口内，以使金属插脚与插口内的金属接触点电连接，从而使充电端口与电池包电导通。正极充电端子31、负极充电端子32和接地端子33的不同结构设计可以满足不同充电端口的使用需求。
示例性的，参阅图1和图3，第二端子组件4包括正极放电端子41和负极放电端子42。参阅图2，连接组件2还包括正极放电导线24和负极放电导线25，正极放电导线24的一端与正极放电端子41连接，另一端与对应的插拔端子21连接，负极放电导线25的一端与负极放电端子42连接，另一端与对应的插拔端子21连接。当电池包需要给车体供电时，待供电端口内的正极导线和负极导线分别与正极放电端子41和负极放电端子42接触连接，以实现电导通，从而使电池包为车体供电。
本实施例中，如图2所示，正极充电导线22远离正极充电端子31的一端通过正极放电导线24与插拔端子21连接，负极充电导线23远离负极充电端子32的一端通过负极放电导线25与插拔端子21连接。即，正极充电导线22和正极放电导线24共用一个插拔端子21，负极充电导线23和负极放电导线25共用一个插拔端子21，布线合理，有利于连接器与电池包的快速连接和拆卸。
示例性的，参阅图2和图3，正极放电端子41和负极放电端子42上均设置有安装槽411，安装槽411用于放置正极放电导线24和负极放电导线25，以增加正极放电导线24与正极放电端子41的接触面积，以及增大负极放电导线25与负极放电端子42的接触面积，保证两两之间连接稳定，接触良好。示例性地，正极放电导线24与正极放电端子41之间焊接，以及负极放电导线25与负极放电端子42之间焊接，连接可靠。在其他实施例中，两两之间也可以采用压装的方式固定连接，只要能够保证接触良好即可。
参阅图2和图4，正极充电导线22、负极充电导线23、正极放电导线24和负极放电导线25均包括金属芯和包覆于金属芯外部的绝缘层，正极充电导线22的金属芯与正极充电端子31焊接，负极充电导线23的金属芯与负极充电端子32焊接，正极放电导线24的金属芯与正极放电端子41焊接，负极放电导线25 的金属芯与负极放电端子42焊接，焊接完成后，在焊接处外部再做绝缘处理，保证多个导线均不漏电，确保电池包的使用安全性。
示例性的，参阅图1，第二凹槽12内设置有第二凸台121，第二凸台121上设置有两个第二插接孔1211，正极放电端子41和负极放电端子42分别设置于对应的第二插接孔1211内。本实施例中，参阅图3，正极放电端子41和负极放电端子42均为设置在第二插接孔1211内壁上的金属圆筒。相应的，待供电端口上设置两个金属插脚，当电池包需要安装在车体上为车体供电时，将两个金属插脚分别对应插入两个第二插接孔1211内，以使金属插脚与金属圆筒接触连接，即可使正极放电端子41和负极放电端子42与待供电端口电连接，实现电池包为车体供电。
示例性的，参阅图1和图3，第三端子组件5包括多个通讯端子51。参阅图5，连接组件2还包括与通讯端子51一一对应设置的通讯导线26，每个通讯导线26的一端均与对应的通讯端子51连接，另一端均与对应的插拔端子21连接。通讯端口与通讯端子51连接后可以在车体(如电动车)的显示屏上显示电量信息等，方便用户了解电池包的电量情况，以及时充电，避免电池包亏电。通讯导线26也包括金属芯和包裹在外部的绝缘保护层，通讯导线26的金属芯与通讯端子51焊接，以实现通讯连接。如图5所示，在通讯导线26与通讯端子51焊接完成后，在焊接处设置热缩管27，热缩管27绝缘耐磨，且能够起到良好的防水密封作用，使得焊接处不会裸露金属，保持通讯连接良好。示例性的，通讯导线26与插拔端子21之间采用粘接胶28(如UV胶)粘接，以使插拔端子21与通讯导线26连接良好。
本实施例中，如图3和图5所示，通讯端子51设置有六个，相应的，通讯导线26也设置六个。在其他实施例中，可根据连接器类型适应性设置通讯端子51的数量。
示例性的，参阅图1，第二凹槽12内设置有第三凸台122，第三凸台122上设置有多个第三插接孔1221，每个通讯端子51均对应设置于一个第三插接孔1221内。本实施例中，参阅图3，通讯端子51为设置在第三插接孔1221内壁上的金属圆筒。相应的，通讯端口内设置多个金属插针，当电池包需要与车体通讯连接时，将通讯端口上的多个金属插针对应插入多个第三插接孔1221内，以使金属插针与金属圆筒接触连接，即可使电池包与通讯端口通讯连接，实现车体与电池包的通讯连接。
在另一个示例的实施例中，多个通讯端子51均为金属插针，金属插针凸起设置于第二凹槽12的底壁上。如图8、图9、图10和图11所示，给出的分别是第三种连接器和第四种连接器的多个通讯端子51的结构类型，多个通讯端子51均为金属插针。相应的，通讯端口内设置有多个插口，每个插口内均设置有金属触点，当通讯端口插入第二凹槽12后，多个金属插针分别对应插入多个插口内，以使金属插针与插口内的金属触点接触连接，从而实现车体与电池包的通讯连接。通讯端子51的不同结构设计可以满足不同通讯端口的使用需求，具 体设计时可根据车体通讯端口的类型设计连接器上通讯端子51的设置方式。
本实施例中，待供电端口与通讯端口为一体成型件，即待供电端口和通讯端口固定在一起，待供电端口与通讯端口同时插入第二凹槽12内，以实现电池包与车体的电连接以及通讯连接，插装连接方便。在其他实施例中，也可将待供电端口和通讯端口分别设置为单独的接口。
示例性的，参阅图1和图3，连接器还包括密封件6，密封件6夹设于座体1与电池包的外壳之间。密封件6能够密封填充连接器的座体1与电池包外壳之间的间隙，以保证外壳上的安装孔密封严实，防止雨天使用电动车时电池包内进水。密封件6可以为橡胶密封圈，橡胶材料弹性性能好，能够起到良好的密封作用，且橡胶材料耐磨，使用寿命长。
为了适应不同车体的待供电端口和通讯端口的使用需求，在一个新的实施例中，示例性的，参阅图8和图10，座体1远离密封件6的一侧设有凸起的第四凸台13，第二凹槽12开设于第四凸台13上。如乔合里连接器的第二端子组件4和第三端子组件5即为图8和图10中的设置方式。
示例性的，参阅图1和图2，座体1上设置有多个连接孔14，座体1通过连接孔14安装于电池包的外壳上。多个连接孔14的设置能够实现连接器与电池包外壳的可拆卸连接，方便后期维护电池包时拆装连接器。示例性的，座体1的四个边角处分别设置一个连接孔14，相应的，电池包的外壳上设置有与连接孔14对应的螺纹孔，在安装连接器时，只需使用螺钉等紧固件穿过连接孔14并旋入螺纹孔即可，安装方便。
示例性的，参阅图2和图3，座体1的每个边角处设置有倒角15。倒角15的设置能够避免连接器上存在尖锐部分，在电池包日常使用过程中能够避免出现磕碰等危险，同时也能够避免座体1上存在应力集中点，从而保护连接器不会碰撞变形。
本实施例还提供一种电池包，包括如上所述的连接器，电池包的外壳上设置有安装孔，连接器安装于安装孔内，并通过插拔端子21与电池包的电池模组插接。采用该连接器的电池包，其外壳上只需开设一个连接器的安装孔，且一个安装孔即可安装不同类型的连接器，节省了开模成本，能够缩短电池包生产周期。同时，电池包上安装一个连接器即可实现电池包的充电、放电、通讯等功能，由于连接器的安装数量减少，使得密封圈的使用数量减少，因此电池包进水的风险也大大降低，能够提高电池的使用可靠性和安全性。并且，在后期电池包需要更换连接器时，只需更换一个连接器即可，降低了电池包的维护成本。此外，通过设置插拔端子21，在后期更换连接器时，只需将电池包内部电池模组的插接端直接与对应的插拔端子21连接即可，无需拆开电池包的外壳，连接器更换速度快，电池包的维护难度和维护成本均降低。
