Abstract

本实用新型公开了一种两段式陶瓷金卤灯电极，铌或铌锆合金杆的前端与钨或合金钨杆连接，铌或铌锆合金杆的直径大于钨或合金钨杆的直径，钨或合金钨杆的前端绕有钨或合金钨丝制成的螺旋电极，钨或合金钨杆的后端装有钼丝绕成的螺旋电极或钼套管电极。本实用新型结构合理、简单，生产过程容易实现自动化；电极钨或合金钨杆头部端面平整、光滑，无毛刺及杂质附著表面，避免了电极启动时的溅射现象；由于钨杆与铌杆之间的紧密完美的连接，保证了产品电阻一致性非常高。

Description

两段式陶瓷金卤灯电极
技术领域：
本实用新型涉及一种陶瓷金卤灯电极。
背景技术：
现有的陶瓷金卤灯电极，都是三段式或四段式设计，这种结构工艺繁复，难以实现自动化生产，产品一致性较难控制。传统电极由于结构设计及加工工艺的局限性，目前尚未找到有效的方法将端面处理光滑，从而导致灯管起动时瞬时高电流将端面的毛刺及杂质挥发污染灯管，降低了灯管的寿命和光效。
发明内容：
本实用新型的目的在于提供一种结构合理，性能优异、使用寿命长的两段式陶瓷金卤灯电极。
本实用新型的技术解决方案是：
一种两段式陶瓷金卤灯电极，其特征是：包括铌或铌锆合金杆，铌或铌锆合金杆的前端与钨或合金钨杆连接，铌或铌锆合金杆的直径大于钨或合金钨杆的直径，钨或合金钨杆的前端绕有钨或合金钨丝制成的螺旋电极，钨或合金钨杆的后端装有钼丝绕成的螺旋电极或钼套管电极。
铌或铌锆合金杆与钨或合金钨杆通过插入式电阻焊形式连接。
本实用新型结构合理、简单，生产过程容易实现自动化；电极钨或合金钨杆头部端面平整、光滑，无毛刺及杂质附著表面，避免了电极启动时的溅射现象；由于钨杆与铌杆之间的紧密完美的连接，保证了产品电阻一致性非常高。
附图说明：
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型一个实施例的结构示图。
具体实施方式：
一种两段式陶瓷金卤灯电极，包括铌或铌锆合金杆1，铌或铌锆合金杆的前端与钨或合金钨杆2连接，铌或铌锆合金杆的直径大于钨或合金钨杆的直径，钨或合金钨杆的前端绕有钨或合金钨丝制成的螺旋电极3，钨或合金钨杆的后端装有钼丝绕成的螺旋电极或钼套管电极4。铌或铌锆合金杆与钨或合金钨杆通过插入式电阻焊形式连接。
