Description

带有充电电缆的蓄电池充电器
本发明涉及权利要求1所述的带有充电电缆和电缆插头的蓄电池充电器。
大部分工业用电瓶车是用蓄电池驱动的，因此自然需要定期对蓄电池充电，充电的方法或者是将蓄电池取下来将其送到充电站，或者在电瓶车上充电，为此需要的充电器可以放在工业电瓶车的外面，或者装在电瓶车上。
典型的充电器应用电力单元，该单元连接于标准的三相电网，或者单相电网，该充电器还包括产生预定电压的达到要求直流电流的整流器。该充电器通过充电电缆连接于蓄电池，更通常的方法是，插座连接于蓄电池上，而插头连接于充电器。为了进行充电，使这些插头和插座彼此连接，对于现在的充电器通常是，电池的充电自动开始。在这一方面，充电器使用一种确定充电器何时连接于蓄电池的装置。另外，充电器还使用手动操作开关，以便起动和结束充电。
如果将充电器的充电插头从蓄电池的插座中拉出时，必须确保在断开时没有电流从充电器流到蓄电池，否则将会产生火花。另外，还存在操作者的手进入插头，碰到插头插销的危险。如果插头插销没有断电，则工作人员可能受到电击。
从DE10151163a1知道，除常规的插头连接件而外，该专利还提供一种指示触头或者辅助触头，在插头一侧的这种辅助触头连接于充电器的控制部分。如果将插头拔出插座，则辅助触头首先反应，并使充电器断电。然而已经证明，拉出插头的时间仅仅在毫秒范围内，如果通过计算机进行检测，该计算机又控制作为时间迟延部件的继电器和接触器，则会产生增大直至充电器断电的时间迟延。
本发明的目的是设计一种充电器充电电缆用的插头，使得充电器可以在插座和插头脱开并及时断电。
利用权利要求所述的特征可以达到此目的。
按照本发明，该插头包括用手可以握住的把手，用该把手将插头从插座中拔出。开关部件连接于该把手，在拉出插头时，可以用手驱动该开关部件。该开关部件通过信号通道连接于充电器。上述连接可以通过充电电缆中另外的导线形成。或者该信号通道本身由充电电缆的导线形成。从该开关部件到充电器的信号传输可以用高频(FH)信号传输。应当明白，开关部件连接于相应的发射部件，而充电器包括相应的接收部件，以便通过充电电缆的导线向充电器传输相应脉冲。
最后，还可以用无线传输通信将信号从开关部件传送到充电器，例如通过无线电或者红外线。在这种情况下，在插头中还需要发射器，而在充电器中还需要接受器，以便在插座和插头断开时进行信号传输，当然还可以看出，在插头和充电器上均配置发射器和接收器，以便在相反方向也能进行通信。
本发明基于这样的认识，为了使插头与插座断开，需要一定拉力，这种拉力通过把手作用在插头的盒子上。上述拉力还可以附加地用于驱动该开关部件。在插头和插座的触头没有以任何方式断开而施加拉力时，该充电器必然及时切断。为了在结构上实现上述想法，可能有各种不同的解决方法。按照本发明实施例的一个解决方法是，该把手包括横向于插头轴线延伸的握紧部分，在该握紧部分的手拉侧配置一个开关部件，当拉力作用在握紧部分时，手便驱动该开关部件。按照本发明的另一实施例，为此所用的开关是所谓波动开关(waveswihch)。该开关装在握紧部分的内侧表面，对应的驱动部分可以用整个手握住，因此拉力也必须作用在该盒子上的拉力。
由此可以想象出，可以在握紧部分或者把手上的开关和充电器之间进行直接连接。然而如果在插头盒子和充电器之间形成信号通道，如上述已经说明的，则是较好的。在这种情况下，可以在开关和插头盒子之间配置辅助电缆，以便将开关产生信号首先输送到插头盒子，然后从该插头盒子输送到充电器。
本发明的另一实施例提出，把手以有限移动方式装在盒子上，而开关部件配置在盒子中，并对把手和盒子的相对移动产生反应。该把手可以由例如U形握紧部分形成，该紧握部分的两个分支端部连接于该盒子。为此，在盒子上配置能够有限移动的支承件，使得拉把手可以引起分支部分相对于盒子移动，这种移动可以利用适当的传感器等进行记录。如果用弹簧沿拉力的反方向拉紧把手，则是方便的。可以通过簧片触点、磁传感器或者通过另外的方式记录该相对移动。
下面详细说明本发明的实施例。
唯一的附图是透视图，示出本发明充电器充电电缆的插头。
在图中，插头总的用编号10表示，该插头包括插头盒子12，该插头盒子在图的左端装有三个插头插销14。外面的插头插销14用于传送电力。该插头插销14连接于电缆16和18，该电缆在图中从盒子12的右端伸出。这些电缆连接于用点线示出的充电器20上，该充电器连接于电源。
该插头10与示意示出的插座22相配合，该插座通过电缆24连接于用点线示出的蓄电池26。整个说来，公开的部件类似于常规系统。
从图中可以看出，U形把手28连接于盒子12，该盒子具有一般为椭圆形的横截面形状。分支部分30和31固定于盒子12的两侧，该分支部分可以以适当方式用螺钉固定在盒子上。还可以想象到，可以使把手28与盒子12形成一体，并用塑料制造。把手28的握紧部分34几乎横向于盒子12的纵轴，并稍微向外弯曲。将条形件36固定在内侧面上，该条形件配合握紧部分34的轮廓，并在中心区域装有开关触头，该触头连接于辅助电缆38。第二开关触头由长部件40形成，该长部件的整个长度几乎在握紧部分的中央部分延伸，并且仍然配合该握紧部分的外轮廓。该长部件以适当方式(未示出)安装并拉紧，使得由此形成的开关通常位于断开的位置。如果操作者握紧握紧部分34，并向图的右侧拉，使力作用在条形件40上，则开关闭合。上述开关是通常用在安全技术、机动车结构等中的波动开关。
该开关通过辅助电缆38连接于盒子12的内部。从该内部可以将开关的状态通过未详细示出的信号通道传送到充电器。该信号通道可以由例如另外的电缆或者电缆16和18中一个电缆中的另外导线形成。在这种情况下，可以选择性地使充电器20中的相应电路通过开关短路或者断开。或者可以在盒子12和充电器20之间产生无线信号，或者用高频通过电缆16和18导线中的一根导线进行传输。
如图所示，还可以在盒子12上安装移动受限的分支部分30和31来代替开关，当握紧把手28，将该把手拉离盒子12，驱动开关部件时，该开关的信号将以上面说明的方式传输到充电器20中。
利用上述示出的可替代的解决方法，可以在插座22和插头10最后断开之前，关掉充电器20。
