本发明涉及电子开关技术领域，尤其是指一种适于长时间使用的电子开关。
背景技术
现有技术中，常规的继电器可以承受大电流，但其接点无法承受长时间大电流所产生的高温，因此在需要历经长时间大电流的情形下，如在寒冷地区起动大型发动机时，容易烧坏。
发明内容
本发明针对现有技术的问题提供一种适于长时间使用、能够耐受长时间大电流的电子开关。
为了解决上述技术问题，本发明采用如下技术方案：一种适于长时间使用的电子开关，包括第一导电散热片、第二导电散热片以及多个继电器，多个继电器的输入端均通过第一导电散热片互相连接，多个继电器的输出端均通过第二导电散热片互相连接。
作为优选，所述第一导电散热片由铜或者铝制成。
作为优选，所述第二导电散热片由铜或者铝制成。
作为优选，所述第一导电散热片的厚度大于或等于0.5毫米。
作为优选，所述第二导电散热片的厚度大于或等于0.5毫米。
作为优选，所述适于长时间使用的电子开关还包括PCB板，所述PCB板设有多个供继电器的输入端穿过的第一通孔以及供继电器的输出端穿过的第二通孔。
作为优选，所述适于长时间使用的电子开关还包括多个焊锡点，一个继电器的输入端通过一个焊锡点与第一导电散热片连接，一个继电器的输出端通过一个焊锡点与第二导电散热片连接。

具体实施方式
为了便于本领域技术人员的理解，下面结合实施例与附图对本发明作进一步的说明，实施方式提及的内容并非对本发明的限定。以下 结合附图对本发明进行详细的描述。
如图1所示，一种适于长时间使用的电子开关，包括第一导电散热片1、第二导电散热片2以及多个继电器3，多个继电器3的输入端(图中未示出)均通过第一导电散热片1互相连接，多个继电器3的输出端(图中未示出)均通过第二导电散热片2互相连接，从而实现多个继电器3的并联。
多个继电器3并联可以对大电流进行分流，使得每一继电器3的负担较小。同时，第一导电散热片1和第二导电散热片2不单能够导电，并且能够快速地散去继电器3接点上的热量，防止继电器3因长时间大电流产生的高温而烧坏。
具体地，所述第一导电散热片1由铜或者铝制成。所述第二导电散热片2由铜或者铝制成。
具体地，所述第一导电散热片1的厚度大于或等于0.5毫米。所述第二导电散热片2的厚度大于或等于0.5毫米。从而保证第一导电散热片1和第二导电散热片2的散热能力。
如图1至图3所示，所述适于长时间使用的电子开关还包括PCB板4，所述PCB板4设有多个供继电器3的输入端穿过的第一通孔41以及供继电器3的输出端穿过的第二通孔42，从而达到利用PCB固定继电器3以防继电器3移位的效果。同时，并联的继电器3还能利用PCB板4与其它元件连接。
如图1所示，所述适于长时间使用的电子开关还包括多个焊锡点5，一个继电器3的输入端通过一个焊锡点5与第一导电散热片1连 接，一个继电器3的输出端通过一个焊锡点5与第二导电散热片2连接。焊锡点5附着在第一导电散热片1或第二导电散热片2上。
如图2所示，所述第一导电散热片1设有多个第一连接孔11，一个继电器3的输入端穿过一个第一连接孔11后与焊锡点5连接，所述第二导电散热片2设有多个第二连接孔21，一个继电器3的输出端穿过一个第二连接孔21后与焊锡点5连接。一方面能够防止继电器3阻碍焊接，另一方面能够增大继电器3的稳定性防止继电器3移位。
以上所述，仅是本发明较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明以较佳实施例公开如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当利用上述揭示的技术内容作出些许变更或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案内容，依据本发明技术是指对以上实施例所作的任何简单修改、等同变化与修饰，均属于本发明技术方案的范围内。
