Description

防水连接器及使用该防水连接器的电池 技术领域
本发明涉及电气连接领域，尤其涉及一种防水连接器及使用该防水连接器的电池。
背景技术
近年来，以动力电池作为储能设备，通过电机驱动的水上\水下产品越来越多。水上电力运动产品，需满足严格的防水要求，特别是电池部分，若防水做的不好，不仅仅会损坏设备，更有可能会发生燃烧、爆炸等安全事故，故在现有产品中为了防水可靠，大部分电池和产品做成不可拆卸的一体。但这样会导致电池的能量密度过低，造成产品的续航时间不够。很多电子产品上面需要使用可插拔的电池，电池的正负极没有保护板，在水环境中使用时，特别是海水中，接头的正负极会产生放电腐蚀。特别是在海水环境下使用，因为海水导电性能好，电阻率低，在海水中会迅速发生电解，一般几十秒就会将电池接头腐蚀到不能使用的程度，一方面损坏连接部，另一方面也影响电池的寿命。电池接通的瞬间形成闭合回路会导致打火花现象，这样会让电池瞬间大量放电，加速电池老化，同时有爆炸等安全隐患。
因此，实有必要提供一种新的防水连接器及使用该防水连接器的电池以解决上述问题。
发明内容
针对以上现有技术的不足，本发明的目的在于提供一种防水连接器及使用该防水连接器的电池，以解决现有技术中密封性不好，可靠性差的问题。
为了解决上述技术问题，本发明提供了一种防水连接器，包括可插接的第二接口和第一接口，所述第一接口包括第一壳体，密封在所述第一壳体内的磁感应元件以及与所述磁感应元件相连的电池保护板，所述磁感应元件控制所述电池保护板上的电子开关控制电池正负极之间的通断，所述第二接口包括第二壳体和设置在所述第二壳体内的磁性元件，所述磁性元件对应所述磁感应元件设置，当所述第二接口与所述第一接口插接在一起时，所述磁性元件激活所述磁感应元件并控制所述电子开关导通。

优选的，所述磁感应元件设置在所述第一外管壁与所述第一内管壁之间，并密封在所述第一本体的防水腔体内，所述磁性元件设置在所述插接部内并与所述磁感应元件对应设置。

与相关技术相比，本发明的防水连接器包括可插接的第一接口和第二接口，所述第一接口与电池的正负极相连，所述第二接口与负载相连，所述第一接口包括第一壳体，密封在所述第一壳体内的磁感应元件以及与所述磁感 应元件相连的电池保护板，所述磁感应元件控制所述电池保护板上的电子开关，并通过所述电子开关控制电池正负极之间的通断，所述第二接口包括第二壳体和设置在所述第二壳体内的磁性元件，所述磁性元件对应所述磁感应元件设置，当所述第二接口与所述第一接口插接在一起时，所述磁性元件激活所述磁感应元件并控制所述电子开关导通。本发明的防水连接器结构简单，安全可靠，不会对电路造成浪涌冲击也不会产生接触火花，且密封性能和防水性能好，可以在水下使用，当电池单独置于水中时，由于电池电源关闭，故电池插头中的正负极不会产生放电腐蚀，很好的保护了插头，保证电池寿命。
附图说明
下面结合附图详细说明本发明。通过结合以下附图所作的详细描述，本发明的上述或其他方面的内容将变得更清楚和更容易理解。附图中：
图1为本发明防水连接器的电路图；
图2为本发明防水连接器的结构示意图；
图3为本发明防水连接器的阶梯剖视图；

具体实施方式
下面结合附图详细说明本发明的具体实施方式。
在此记载的具体实施方式/实施例为本发明的特定的具体实施方式，用于说明本发明的构思，均是解释性和示例性的，不应解释为对本发明实施方式及本发明范围的限制。除在此记载的实施例外，本领域技术人员还能够基于本申请权利要求书和说明书所公开的内容采用显而易见的其它技术方案，这些技术方案包括采用对在此记载的实施例的做出任何显而易见的替换和修改的技术方案，都在本发明的保护范围之内。下面结合具体实施例进行说明:
请参图1-4所示，本发明提供了一种防水连接器和使用该防水连接器的电池，防水连接器包括与电池相连的第一接口1和与负载相连的第二接口2，第一接口1和第二接口2可插接在一起实现负载与防水电池的电导通。
第一接口1包括第一壳体，密封在第一壳体内的磁感应元件3以及与所 述磁感应元件相连的电池保护板。第二接口2包括与第一壳体相组配的第二壳体和设置在第二壳体内与磁感应元件3相对应设置并相互感应的磁性元件4。其中第一壳体和第二壳体均为塑料材质，其防腐蚀和绝缘性较好，从而确保了产品的可靠性能。
具体在本实施方式中，磁感应元件3为干簧管，在可选择的其他实施方式中，也可以为霍尔元件或其他磁感应开关。磁性元件4可以为自身具有磁性的磁体，也可以为在一定外界条件下可以具有磁性的致磁元件，例如电磁铁等，通过上电或断电产生磁场来触发磁感应元件3。电池保护板BMS(BATTERY MANAGEMENT SYSTEM)包括MCU(微控制单元，Microcontroller Uni)模块和功率开关管。具体在本实施方式中，功率开关管为MOS(metal oxid semiconductor，场效应晶体管)模块。MCU模块检测所述干簧管的状态并输出相应信号通过MOS模块管控电源的开启和断开。干簧管的两端均与电池保护板相连接。电池保护板与电池的电芯相连接，电池保护板设置在电芯的正极，所述电池保护板的地与电芯负极连接。
如图1所示，电池保护板既可以设置在电池的正极端，控制正极的输出或断开，也可以设置在负极端，控制负极的输出或断开，或者设置在电池的正极与负极之间，通过电子开关实现正极与负极的连通，只要能够控制电池的整体输出，即是可以实施的。
如图2和图3所示，第一壳体包括具有防水腔体10的第一本体11、自第一本体11延伸的第一外管壁12、收容在第一外管壁12内的环状的第一内管壁13，第二壳体包括第二本体21和自第二本体21延伸的环状的插接部22以及设置在插接部22内部的定位部23。
当第一接口1和第二接口2插接在一起时，插接部22插入第一外管壁12和第二内管壁13之间形成的间隙内，插接部22的外表面对应第一外管壁12的内表面，插接部22的内表面对应第一内管壁13的外表面。优选的，插接部22抵接在第一外管壁和第一内管壁上，同时，定位部23插接在第一内管壁13内，第一外管壁12抵接在第二本体21上，从而实现第一接口1和第二接口2的插接固定。进一步的，第一壳体和第二壳体之间还设置有用于加强密封性能的密封圈5。在本实施方式中，密封圈5设置在第二壳体的外表面上，具体为设置在第一外管壁12与插接部22之间。该密封圈5可以为一个，也可以为多个，其设置位置可以如本实施方式的位置，也可以在其 他位置设置，只要实现第一接口1与第二接口2之间的密封，即是可以实施的。当然，这仅是一种可实施的方式，在可选择的其他实施方式中，第一接口也可以通过线缆穿过电池外壳与电池壳内的电芯连接，此时则电池外壳与线缆初需要防水处理。
进一步的，第二接口2和第一接口1中的任意一个上设置有卡扣6，第二接口2和第一接口1中的另一个上设置有与卡扣6相匹配的卡槽7。具体在本实施方式中，卡扣6设置在所述第二本体21上，卡槽7设置在第一外管壁12的外表面上。这样，当第二接口2插入第一接口1后，可以将卡扣6扣入卡槽实现两者的稳定连接。
如图1和图4所示，为了提高信号的拾取能力，优选的，干簧管与电池保护板之间还设置有用于放大信号的放大电路。干簧管和放大电路均密封设置在第一本体11的防水腔体10内。在可选择的其他实施方式中，也可以用霍尔元件或其他磁感应开关替换干簧管。其中干簧管为无源开关，霍尔元件为有源开关，必须供电才能工作。使用这两种开关器件的电路结构会有一些不同。若采用干簧管，则无需设置放大电路，而是设置信号检测电路，若采用霍尔元件，则需要设置放大电路。本实施方式以磁感应元件3为干簧管为例进行说明，当然，在可选择的其他实施方式，将电路结构进行适当修改，采用霍尔元件作为开关器件，其原理也是相同的。
干簧管设置在第一外管壁12与第一内管壁13之间，所述磁性元件4设置在插接部22内并与干簧管对应设置。磁性元件4也密封设置在第二壳体内，与水进行隔离以防止腐蚀生锈或消磁。
当第二接口2插接到第一接口1时，磁性元件4块移动到干簧管有效距离之内，其磁场会激活导通干簧管，最终电池的正、负极带电连接电池和负载，从而实现电池放电功能；当第二接口2拔出第一接口1时，磁性元件4移动到干簧管有效距离之外，干簧管失去磁场作用而断开，从而实现电池关闭功能；
而当第二接口2与第一接口1断开时，连接器的正负极不导通，电池正负极物理断开，两者之间没有电压，所以在水中是不会发生电腐蚀。防水连接器接插的过程中，在插连接器的过程中，第一接口1和第二接口2的正负极已经对应物理接触和连接了，所以再上电就不会产生打火花现象，可以起到防电火花的作用。
本发明还提供一种电池，包括如上的防水连接器和电芯，电池保护板的电子开关设置在电芯的正极之间，所述电池保护板的地与电芯负极连接，当所述第一接口与所述第二接口插接后，磁感应元件在磁性元件的作用下触发所述电子开关，所述电子开关连接所述电芯的正负极使所述负载上电。
与相关技术相比，本发明的防水连接器包括可插接的第一接口和第二接口，所述第一接口与电池的正负极相连，所述第二接口与负载相连，所述第一接口包括第一壳体，密封在所述第一壳体内的磁感应元件以及与所述磁感应元件相连的电池保护板，所述磁感应元件控制所述电池保护板上的电子开关，并通过所述电子开关控制电池正负极之间的通断，所述第二接口包括第二壳体和设置在所述第二壳体内的磁性元件，所述磁性元件对应所述磁感应元件设置，当所述第二接口与所述第一接口插接在一起时，所述磁性元件激活所述磁感应元件并控制所述电子开关导通。本发明的防水连接器结构简单，安全可靠，不会对电路造成浪涌冲击也不会产生接触火花，且密封性能和防水性能好，可以在水下使用，当电池单独置于水中时，由于电池电源关闭，故电池插头中的正负极不会产生放电腐蚀，很好的保护了插头，保证电池寿命。
需要说明的是，以上参照附图所描述的各个实施例仅用以说明本发明而非限制本发明的范围，本领域的普通技术人员应当理解，在不脱离本发明的精神和范围的前提下对本发明进行的修改或者等同替换，均应涵盖在本发明的范围之内。此外，除上下文另有所指外，以单数形式出现的词包括复数形式，反之亦然。另外，除非特别说明，那么任何实施例的全部或一部分可结合任何其它实施例的全部或一部分来使用。
