翼片 222设置于套件主体 221上并向灯管 21的侧向延伸。翼片 222优选与 套件主体 221—体成型。 具体来说, 在本实施例中, 将第一套筒 2211的侧壁切 割出一条形区域, 并将该条形区域向灯管 21的侧向弯折, 进而形成翼片 222。 翼片 222也可以通过其他方式形成并设置于套件主体 221上, 例如翼片 222为 以适当方式形成的独立的导电部件,并通过焊接或其他方式固定于套件主体 221 上。 在本实施例中, 翼片 222的数量为两个, 并分别形成于套件主体 221 的两 侧。 同时, 翼片 222在垂直于灯管主体 211 的方向上的截面呈矩形。 在其他实 施例, 翼片 222的数量可以根据需要设计成一个或多个, 并且翼片 222的形状 也可以根据需要设计成其他形状。
第一绝缘插件 23设置有第一通孔 231、 第二通孔 232及盲孔 233。 第一通 孔 231连接第一绝缘插件 23的相对两侧 (如图 3所示的第一绝缘插件 23的上 下两侧), 以允许套件主体 221穿设于第一通孔 231中。 第一通孔 231进一步允 许套件主体 221穿过第一绝缘插件 23。 第二通孔 232与第一通孔 231连接且连 接第一绝缘插件 23的相对两侧 (如图 3所示的第一绝缘插件 23的上下两侧 ), 以允许翼片 222穿过第一绝缘插件 23。 盲孔 233与第一通孔 231连接且连接第 一绝缘插件 23的远离灯管 21的侧面 (如图 3所示的第一绝缘插件 23的上侧 ), 以允许翼片 222从远离灯管 21的一侧设置并支撑于盲孔 233内。 翼片 222与盲 孔 233之间优选为紧密配合。 在本实施例中, 与翼片 222对应, 第二通孔 232 和盲孔 233的数量也分别为两个, 且以第一通孔 231为中心呈十字形排列。 同 时, 第二通孔 232和盲孔 233在垂直于灯管主体 211的方向上的截面也呈矩形。 在其他实施例, 第二通孔 232和盲孔 233的数量和形状可根据翼片 222对应地 进行变化。
第二绝缘插件 24包括绝缘主体 241、 导电弹片 242及立柱 243。 导电弹片 242设置于绝缘主体 241内,且导电弹片 242的两端从绝缘主体 241的相对两侧 外露。 导电弹片 242可通过注塑方式设置于绝缘主体 241 内。 立柱 243设置于 绝缘主体 241的靠近灯管 21的侧面, 立柱 243插置且固定于第二通孔 232内, 进而使得第二绝缘插件 24固定于第一绝缘插件 23上。 立柱 243可通过注塑方 式与绝缘主体 241—体成型。 当第二绝缘插件 24固定于第一绝缘插件 23上时, 导电弹片 242的一端 4氐触位于盲孔 233的翼片 222上。 在优选实施例中, 立柱 243与第二通孔 232之间为过盈配合。 在其他实施例中, 第二绝缘插件 24也可 以通过其他方式固定于第一绝缘插件 23上, 例如通过粘胶固定、 卡扣配合或螺 丝固定等方式。 此外, 导电弹片 242 的一端优选具有弯折结构, 以弹性 4氏触翼 片 222。 在本实施例中, 与第二通孔 232和翼片 222对应, 立柱 243和导电弹片 242的数量也为两个, 同时立柱 243在垂直于灯管主体 211的方向上的截面也呈 矩形。 在其他实施例, 立柱 243和导电弹片 242的数量以及立柱 243的形状可 根据第二通孔 232和翼片 222对应地进行变化。
在本实施例中,绝缘主体 241的靠近灯管 21的侧面上进一步设置盲孔 244 , 盲孔 244用于接收灯管 21的引脚 212以及导电套件 22的第二套筒 2212, 由此 可减小第一绝缘插件 23的长度。
导线 25的一端通过焊接或其他方式电连接到导电弹片 242的另一端。连接 器 26通过焊接或其他方式电连接到导线 25的另一端。 连接器 26进一步与设置 于电路板 27上的外部连接器 28连接。
下面将详细说明该光源组件的组装过程:
首先,将导电套件 22的套件主体 221套设并固定于灯管主体 211的端部上 并与引脚 212电连接。 随后, 将导电套件 22的套件主体 221和翼片 222分别经 过第一通孔 231和第二通孔 232穿过第一绝缘插件 23。 然后, 将导电套件 22旋 转 90度, 并将翼片 222从第一绝缘插件 23的远离灯管 21—侧设置并支撑于盲 孔 233内。 接着, 将第二绝缘插件 24上的立柱 243插置且固定于第二通孔 232 内, 并使得导电弹片 242的一端抵触位于盲孔 233 内的翼片 222上。 最后, 将 导线 25的一端与导电弹片 242的另一端电连接, 并将导线 25的另一端与连接 器 26电连接。
在本发明中, 第二通孔 232以及立柱 243可以省略。 此时, 首先通过第一 通孔 231将第一绝缘插件 23套设在灯管主体 211上, 再将导电套件 22的套件 主体 221套设并固定于灯管主体 211的端部上。 随后, 从第一绝缘插件 23的远 离灯管 21—侧将套件主体 221穿设于第一通孔 231内, 并将翼片 222设置并支 撑于盲孔 233 内。 接着, 利用粘胶固定、 卡扣配合或螺丝固定等其他固定方式 将第二绝缘插件 24的绝缘主体 241 固定于第一绝缘插件 23上, 并使得导电弹 片 242的一端 ·ί氐触位于盲孔 233内的翼片 222上。
本发明进一步提供了一种液晶显示器, 该液晶显示器包括上述实施例中的 光源组件。
通过上述方式, 由于导线 25 ;t早接到导电弹片 242上, 因此本发明的光源组 件以及液晶显示器能够避免在将导线焊接到灯管引脚上时对灯管造成破坏, 具 有节约成本等优点。 以上所述仅为本发明的实施例, 并非因此限制本发明的专利范围, 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运 用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
