Description

连接器和使用该连接器的LED照明设备
技术领域
本发明涉及照明技术领域，具体涉及一种用于LED照明设备光源板与驱动板之间电连接的连接器，以及使用该连接器的LED照明设备。
背景技术
传统技术中，LED照明设备的光源板与驱动板之间电连接通过导线实现，即将导线的两端分别手工焊接在光源板和驱动板上，从而为光源板上的LED光源供电。这种电连接方法耗时耗力，无法实现自动化组装，并且可靠性差，容易造成短路。
为改进光源板与驱动板的电连接方式，技术人员研发了各种直插式连接器，例如专利申请CN201210562730.1，CN201310527555.7中所揭示的两种连接器。直插式连接器在光源板上安装连接用插座，在驱动板上安装连接用插针，简化了传统手工焊接导线的工艺，使连接操作更加方便，可实现自动化组装加工。但是，现有直插式连接器还存在结构复杂、成本较高、可适性差等问题。例如，现有连接器使用了金属和塑料绝缘材料，造成设计和加工工艺复杂，对组装精度要求高，从而报废率较高，另外，爬电距离不可调，不能适应不同大小的LED照明设备，可适性较差。
发明内容
有鉴于上述问题，本发明的一个方面在于提供一种用于LED照明设备光源板与驱动板之间电连接的连接器，所述光源板有至少一个通孔允许所述驱动板的一部分穿过，驱动板穿过光源板的部分上有至少两个触点用于与连接器电连接，该连接器包括两个或两个以上导电端子，每个导电端子包括至少两个将导电端子固定在光源板上的安装部、一个连接所述至少两个安装部的支撑架和一个将导电端子与驱动板穿过光源板的部分上的触点电连接的弹臂。本发明的导电端子的形状、大小可以根据需要，如电流大小、爬电距离，进行调节，以适应各种LED照明设备。
对于本发明的连接器，弹臂与驱动板穿过光源板的部分上的触点弹性地接触，从而实现导电端子与驱动板的电连接。
对于本发明的连接器，至少一个弹臂是悬臂的形式，即包括一个固定端和一个自由端，其中，固定端与导电端子的其中一个安装部或支撑架相连接起固定作用，自由端向侧方延伸，用于与驱动板穿过光源板的部分上的触点相接触。具体地，作为悬臂的一种实施方式，悬臂的固定端与其中一个安装部相连接或相靠近，悬臂的自由端向光源板的通孔方向延伸，与驱动板穿过光源板的部分上的触点相接触；作为悬臂的另一种实施方式，悬臂的固定端与支撑架相连接并远离任一安装部，悬臂的自由端向光源板的通孔方向延伸，与驱动板穿过光源板的部分上的触点相接触。悬臂可以以各种形状存在，例如片状、棒状等，可以是直线的，也可以是弯曲形。另外，在不影响支撑架的连接功能前提下，悬臂可以由支撑架的一部分弯曲形成。
对于本发明的连接器，至少一个导电端子还包括第二个弹臂，该第二个弹臂与导电端子的安装部或支撑架其中之一相连接，并与驱动板穿过光源板的部分弹性地相接触，起到固定驱动板位置的作用。此时，第一个和第二个弹臂均与驱动板穿过光源板的部分相接触，使驱动板与光源板的连接在结构上更牢固。优选地，所述两个弹臂分别与驱动板穿过光源板部分的两侧相接触。更优选地，所述两个弹臂形状相同，关于驱动板对称。
对于本发明的连接器，至少一个导电端子由导电金属一体加工成型制造，例如由片材冲压形成。
本发明的另一个方面在于提供一种LED照明设备。该LED照明设备包括一个光源板，所述光源板上有至少一个LED光源和至少一个通孔；一个驱动板，所述驱动板的一部分可穿过光源板的通孔，驱动板穿过光源板的部分上有至少两个触点；以及一个安装在光源板上用于实现光源板与驱动板电连接的连接器，所述连接器包括两个或两个以上导电端子，每个导电端子包括至少一个将导电端子固定在光源板上的安装部和一个将导电端子与驱动板穿过光源板的部分上的触点电连接的弹臂。本发明采用驱动板的一部分穿过光源板的设计，驱动板上无连接插针设计，从而结构更简单，LED照明设备的组装更容易。
对于本发明的LED照明设备，作为一种实施方式，其连接器的每个导电端子包括至少两个将导电端子固定在光源板上的安装部、一个连接所述至少两个安装部的支撑架和一个将导电端子与驱动板穿过光源板的部分上的触点电连接的弹臂。
对于本发明的LED照明设备，驱动板穿过光源板的部分是一个与驱动板整体宽度相比较窄的突出部分，驱动板整体呈“凸”字形，该突出部分上有至少两个触点，光源板有一个使该驱动板突出部分穿过的通孔。作为另一种实施方式，驱动板穿过光源板的部分可以包括两个或两个以上突出部分，各突出部分上分别有一个触点，光源板有一个使该驱动板所有突出部分穿过的通孔，或者光源板上有与驱动板突出部分相同数目的通孔，可使驱动板的各突出部分分别穿过。
对于本发明的LED照明设备，驱动板上的触点为驱动板表面的焊点，如焊锡点，或驱动板上的金属部分。
