Abstract

本实用新型涉及一种用于架空绝缘导线连接的穿刺线夹,包括两个通过螺栓互相扣合的上盖和下盖,在两者的侧壁上各设有二个缺口拼合成主线夹口和支线夹口,在上、下盖内还设有若干对配合的穿刺刀片,下盖内设有绝缘套筒,螺栓则从上盖顶部穿入经过该绝缘套筒,并且在穿刺刀片位置处填充有充足的绝缘脂。本实用新型的结构紧凑,绝缘性强,可用于高压绝缘导线连接,并且穿刺导电部分遮盖严密,防水密封。

Description

穿刺线夹
技术领域:本实用新型涉及一种用于架空绝缘导线连接的穿刺线夹。
背景技术:一般的穿刺线夹的上、下盖通过螺栓连接扣合,螺栓在盖体内的位置距离穿刺刀片较近,在高压情况下可能产生放电,绝缘性还不够强。如果将螺栓和穿刺刀片布置得较远,则结构体积会较大,用于高压连接中的绝缘性也还不够。并且,在穿刺刀片的刀刺处一般都设有橡胶垫,用于穿刺入导线绝缘外皮后变形填充空隙,但橡胶垫填充不够严密,密封防水性不可靠。
发明内容:针对现有技术的不足,本实用新型提供一种绝缘性强,密封防水可靠的穿刺线夹。
本实用新型包括两个通过螺栓互相扣合的上盖和下盖,在两者的侧壁上各设有二个缺口拼合成主线夹口和支线夹口,在上、下盖内还设有若干对配合的穿刺刀片,下盖内设有绝缘套筒,螺栓则从上盖顶部穿入经过该绝缘套筒,并且在穿刺刀片位置处填充有充足的绝缘脂。
本实用新型的结构紧凑,螺栓套于绝缘套筒内,和穿刺刀片的隔离绝缘性很强,可以用于高压绝缘导线连接,而且,穿刺刀片刺入绝缘导线后绝缘脂自然流动填充空隙,电气接触部分绝缘遮盖很严密,安全可靠,密封防水性能非常好。
下面结合附图和实施例进一步说明本实用新型。
附图说明:图1是实施例的主示意图;
          图2是图1的A-A剖视图。
实施例:如图所示,上盖1和下盖2通过螺栓3互相扣合,在两者的侧壁上各设有二个缺口拼合成主线夹口4和支线夹口5,在上盖1和下盖2内还设有若干对配合的穿刺刀片6。下盖2内设有绝缘套筒7,螺栓3则从上盖1顶部穿入经过该绝缘套筒7,并且在穿刺刀片6位置处填充有充足的绝缘脂8。
使用时,将主线夹口4和支线夹口5分别夹住主绝缘导线及支线,拧紧螺栓3使穿刺刀片6穿刺入导线的绝缘外皮,这样主、支线即可通过穿刺刀片6导通,穿刺时绝缘脂8会自然填充空隙,防水密封。根据线夹的大小,螺栓3可用不同数目,本实施例用二个,并且在螺栓3的头部设有力矩螺母9构成穿刺压力控制装置,这样当拧紧力矩一定时,无法再持续拧紧,防止穿刺刀片6穿刺过大损伤导线。在螺栓3的头部和上盖1上端面之间可垫有蝶型弹性垫圈10,可以防止导线长期使用抖动使线夹松开的现象。
