Description
卡口灯头
技术领域
[0001] 本实用新型涉及灯头领域技术，更具体地说，它是一种卡口灯头。 背景技术
[0002] 卡口灯头是白炽灯和电子节能灯的重要部件，传统的卡口灯头包括卡钉、壳体、绝 缘体和导线，卡钉对称设置于壳体两侧，绝缘体采用玻璃或陶瓷材料充满整个壳体中，将导 线浇注并固定于其中。这种结构的卡口灯头，绝缘体材料耗费大、工艺生产成本高、生产耗 能大，后期组装效率低，难以实现自动化生产且成品率低，不能满足现代工业生产对卡口灯 头数量和质量的要求。
发明内容
[0003] 针对现有技术的不足之处，本实用新型的目的是提供一种工艺简单、生产成本低、 节能降耗和生产效率高的卡口灯头。
[0004] 为达到上述目的，本实用新型是通过以下技术手段来实现的：一种卡口灯头，包括 卡钉、壳体、导电触点和绝缘体，卡钉对称设置于壳体两侧，壳体为两端开口的筒体，绝缘体 注塑在壳体的顶部，绝缘体上设有分别贯通灯头内外的两导线孔，两导线孔的外部端口上 分别设有导电触点，绝缘体的端面上设有与导电触点相适配的凹槽，导电触点的下缘置于 该凹槽中，所述的绝缘体的中间端面为弧形凸起。
[0005] 更进一步的，所述的导电触点与绝缘体及导线接触面设有防脱倒扣。
[0006] 本实用新型的有益效果是：由于采用上述结构，将由塑胶制成的绝缘体直接注塑 到壳体的顶部，工艺简单，节约成本，免焊锡，生产效率高，不良率低，大大提高卡口灯头的 后期组装效率；绝缘体中间端面采用弧形凸起结构，可有效的保护触点，以及生产定位•’导 电触点与绝缘体及导线接触面设置的防脱倒扣，使得导电触点与绝缘体的连接更可靠。本 实用新型结构简单、设计巧妙，工艺简单、生产成本低，节能降耗、生产效率高、可广泛应用 于白炽灯和节能灯领域，具有广泛的市场空间和巨大的市场潜力。
附图说明
[0007] 附图1为本实用新型的结构示意图；
[0008] 附图2为本实用新型防脱倒扣的结构示意图。
[0009] (5) (6)导线孔，(7) (8)凹槽，(9) (10)导电触点，(11)防脱扣。
具体实施方式
[0010] 下面结合附图对本实用新型做进一步的详细说明：
[0011] 参看附图1，2，本实用新型一种卡口灯头，包括卡钉2、3、壳体1和绝缘体4，卡钉 2、3对称设置于壳体1两侧，壳体1为两端开口的筒体，绝缘体4注塑在壳体的顶部，绝缘体 4上设有分别贯通灯头内外的两导线孔5、6，两导线孔5、6的外部端口上分别设有导电触点9、10，绝缘体4的端面上设有与导电触点相适配的凹槽7、8，导电触点9、10的下缘置于该凹 槽7、8中，所述的绝缘体4的中间端面为弧形凸起；所述的导电触点9与绝缘体4及导线接 触面设有防脱倒扣U。
[0012] 以上所述，仅是本实用新型一种较佳实施例而已，并非对本实用新型的技术范围 作任何限制，凡是依据本实用新型的技术实质对上面实施例所作的任何细微修改、等同变 化与修饰，均仍属于本实用新型技术的范围内。
