Abstract

一种短节距薄型LED引线框架，包括工艺边，工艺边上均匀开有工艺孔，与工艺边垂直连接有多根LED二管脚引线，LED二管脚引线之间通过上连筋连接，相邻的两个LED二管脚引线中心线之间的距离即节距a小于7.62毫米。用于制造引线框架的钢带厚度小于0.5毫米。本发明缩短了单根LED引线框架上相邻的两个LED二管脚引线中心线之间的距离减少了所用钢带的厚度，使每支引线框架上可以布置更多的LED二管脚引线，减少了钢带使用量，降低了生产成本。

Description

短节距薄型LED引线框架
技术领域
本发明涉及一种生产LED即发光二级管的引线框架，特别是一种短节距薄型LED引线框架。
背景技术
LED即发光二极管属于绿色环保光源，在指示灯、装饰灯、景观灯、手电用灯、交通信号灯、汽车灯、道路照明灯等灯具上得到广泛运用，逐步将取代传统照明用灯，LED以特有冷光源、能耗低、效率高、寿命长等性能使其用途越来越广，但由于封装制作成本高，造成LED成本较高，影响和阻碍了LED的运用和发展。目前直插式LED封装通用的引线框架工艺边长度为152.4毫米，节距均为7.62毫米，钢带厚度为0.5毫米，节距距离较大，使钢带较厚，增加了钢带的消耗量。
发明内容
本发明的目的是要提供一种在保障LED质量的基础上，降低LED引线框架的用钢量，降低生产成本的短节距薄型LED引线框架。
本发明的目的是这样实现的：一种短节距薄型LED引线框架，包括工艺边，工艺边上均匀开有工艺孔，与工艺边垂直连接有多根LED二管脚引线，LED二管脚引线之间通过上连筋连接，相邻的两个LED二管脚引线中心线之间的距离即节距a小于7.62毫米。用于制造引线框架的钢带厚度小于0.5毫米。相邻的两个LED二管脚引线中心线之间的距离即节距a为5.08毫米。用于制造引线框架的钢带厚度为0.4毫米。
本发明提供的短节距薄型LED引线框架，缩短了单根LED引线框架上相邻的两个LED二管脚引线中心线之间的距离即节距，以前每条20支的引线框架上可以布置更多的LED二管脚引线。LED引线框架节距为5.08毫米、钢带厚度0.4为毫米的LED引线框架就比传统的节距均为7.62毫米，钢带厚度为0.5毫米的LED引线框架钢带用量节约46.66％，降低了生产成本。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明的结构示意图。
具体实施方式
如图1所示，本发明包括工艺边1，工艺边1上均匀开有工艺孔2，与工艺边1垂直连接有多根LED二管脚引线3，LED二管脚引线3之间通过上连筋4连接。
本发明中，引线框架工艺边长度b为152.4毫米，与普通引线框架的长度相同。相邻的两个LED二管脚引线3中心线之间的距离即节距a小于7.62毫米，为7.5毫米、7.1毫米、6.8毫米、6毫米、5.8毫米、5.1毫米、5.08毫米、5.01毫米、4.98毫米等，在满足工艺要求的前提下尽量缩短节距a，以节省钢带用量。
用于制造引线框架的钢带厚度小于0.5毫米，常用的为0.4毫米。
