Description

头箍型连接器及应用此头箍型连接器的LED灯 技术领域
本发明涉及连接器的技术领域，特别涉及一种适用于LED灯光源板的头箍型连接器，以及应用此头箍型连接器的LED灯。
背景技术
现有技术中，LED灯的电源连接是利用导线来实现，即将导线的两端分别焊接在光源板和驱动板上，实现为光源板上的LED芯片供电。这种电连接操作十分麻烦，造成LED灯组装成本高，无法实现自动化组装。
后有业者研发了各种直插式结构，即在光源板上安装连接器，在驱动板上安装插针，借助插针插入连接器中可以代替导线连接，简化了LED灯的光源板和驱动板的电连接结构，连接操作更加方便，组装加工更加容易，可以实现自动化生产。
但是，现有的直插式结构还是较为复杂，特别是安装在光源板上的连接器体积较大，不适应制造小型LED灯，应用范围受到限制。
发明内容
本发明的一个目的在于提供一种头箍型连接器，使其结构更简单，安装结构更紧凑，适于制造大小不同型号的LED灯，应用范围更广。
本发明的另一个目的在于提供一种LED灯，使其结构更简单，安装结构更紧凑。
为了实现上述目的，本发明的技术方案如下：
一种头箍型连接器，包括底板，底板上具有焊脚供与光源板实现电连接，底板上开设供插针穿过的插口，底板的左右两个侧边先向上延伸再相对延伸至插口上方再弯折形成弹性夹供插针插入实现电连接。
所述底板的左右两个侧边先向上延伸，再相对延伸至插口上方，然后向下弯折形成弹性夹。
所述底板的左右两个侧边先向上延伸，再相对延伸至插口上方，然后向上弯折形成弹性夹。
所述底板的左右两个侧边先向上延伸，再相对延伸至插口上方，然后向上延伸再向左右延伸，弯折形成弹性夹。
所述底板的左右各形成两个焊脚，即在底板的四个角上都有一个焊脚，一共有四个焊脚。
所述底板的前后各形成一个焊脚，即一共有两个焊脚；具体可以是底板的前后各向下延伸，再向外或向内弯折形成焊脚；此焊脚可以进一步向左右延伸，以增大焊接面积，使安装更稳固。
所述弹性夹形成导入角供导引插针插入。
所述头箍型连接器由一片材冲压后弯折而成。
一种LED灯，在LED灯的内部安装驱动板和光源板，驱动板位于光源板的下方，光源板上安装头箍型连接器，光源板上对应插口开设供插针穿过的开口，驱动板上安装插针或一体成型插针，通过插针插入头箍型连接器的弹性夹实现电连接。
所述插针对应光源板开口的位置套有绝缘套。
采用上述方案后，本发明与现有技术相比，利用底板的焊脚供与光源板实现电连接，利用底板的左右两个侧边延伸并弯折形成弹性夹供插针插入实现电连接，使本发明结构更简单，可省去安装用塑胶座，安装结构更紧凑，可以适于制造大小不同型号的LED灯，特别是小型LED灯，应用范围更广。
本发明的LED灯，因安装结构更紧凑，所以同样大小的LED灯，使光源板上可以布置更多的LED光源，适于制造大功率的LED灯。
以下结合附图及具体实施例对本发明做进一步详细说明。

标号说明
头箍型连接器10，底板11，焊脚12，插口13，弹性夹14，导入角15，光源板20，开口21，插针30，绝缘套31，驱动板40，塑胶座50。
具体实施方式
如图1至图8所示，是本发明揭示的一种头箍型连接器10的五个实施例，包括底板11。
底板11上具有焊脚12，焊脚12供与光源板20实现电连接。图1所示实施例一和图5所示实施例三中，底板11的左右各形成两个焊脚12，一共有四个焊脚12，即在底板11的四个角上都有一个焊脚12。图4所示实施例二中，底板11的前后各形成一个焊脚12，即一共有两个焊脚12。图6所示实施例四和图7所示实施例五中，底板11的前后各形成一个焊脚12，即一共有两个焊脚12。其中，图6的实施例四之底板11的前后各向下延伸，再向内弯折形成焊脚12，图7的实施例五之底板11的前后各向下延伸，再向外弯折形成焊脚12。实施例四和实施例五进一步将焊脚12向左右延伸，以增大焊接面积，使安装更稳固实施例一至实施例五的区别是焊脚12的位置和结构不同，可适用于不同排布的LED光源板20。
底板11上开设插口13，插口13供插针30穿过。
底板11的左右两个侧边先向上延伸，再相对延伸，至插口13上方时再弯折，使两个侧边在插口13的上方形成弹性夹14，弹性夹14供插针30插入实现电连接。图1和图4中所示，底板11的左右两个侧边至插口13上方时是向下弯折，这样结构简单，也可以做其它形状的弯折，以形成弹性夹14，以增加弹性。弹性夹14的下端还形成导入角15，导入角15可导引插针30插入。图5至图8中所示，底板11的左右两个侧边至插口13上方时先向上延伸再向左右延伸，弯折形成弹性夹14，这样结构可以增加弹性和强度。弹性夹14对应插口13的上方向上弯折时直接形成导入角15，导入角15可导引插针30插入。
本发明的底板11经上述变形后，整体形状就像孙悟空头上戴的金箍，故称之为头箍型连接器。
从图1和图8可见，本发明的头箍型连接器结构简单，可以由一片材冲压后弯折而成。这使得本发明成本大大降低。本发明安装时可省去安装用塑胶座，安装结构更紧凑，可以适于制造大小不同型号的LED灯，特别是小型LED灯，应用范围更广，而且，同样大小的LED灯，因本发明的安装结构更紧凑，使电源板上可以布置更多的LED光源，适于制造大功率的LED灯。
本发明的头箍型连接器运用于LED灯时，以实施例一为例，如图3所示，对应在LED灯的内部安装光源板20和驱动板40，驱动板40位于光源板20的下方，光源板20上安装上述头箍型连接器10，光源板20上对应插口13开设开口21供插针30穿过，驱动板40上借助塑胶座50安装插针30（插针是冲压成型件或导线）或直接安装插针30（如图8和图9所示插针30就是采用焊接），驱动板40也可以一体成型插针30（PCB板），通过插针30插入头箍型连接器20的弹性夹14中实现电连接，达到照明功效。
为了更好地进行连接安装，避免短路现象，特别是方便与开口21小的光源板20配合安装，本发明在插针30对应光源板20开口21的位置套有绝缘套31。
以上仅为本发明的具体实施例，并非对本发明的保护范围的限定。凡依本案的设计思路所做的等同变化，均落入本案的保护范围。
