Description

张力过载保护型电缆头
技术领域
本实用新型涉及油、气井测试领域一种电缆头，特别是一种用于金属护套探测电缆张力过载保护型电缆头。
背景技术
目前油、气井金属护套探测电缆测试相关技术领域中，通常使用的电缆头采用自锁式固定结构。由于自锁式固定结构的局限性，当电缆头受张力过大，电缆不能顺利脱开，给电缆保护和相关测试仪器的正常使用埋下隐患。
发明内容
本实用新型解决的技术问题是目前油、气井测试领域中，通常使用的电缆头具有自锁性、过载不能保护。本实用新型设计一种张力过载保护型电缆头，包括电缆头上接头、模具弹簧、调整垫片、内锥夹紧头、外锥夹紧头、锁紧块，其特征在于：电缆头上接头内置有模具弹簧，模具弹簧末端压调整垫片，调整垫片另一端压外锥夹紧头，外锥夹紧头外套着内锥夹紧头，内锥夹紧头末端压着锁紧块，锁紧块与电缆头上接头螺纹连接。本实用新型的优点是结构简单，准确可靠，预置张力，过载保护，适用于更多场合。
附图说明
附图1是本实用新型的结构示意图。
具体实施方式
图中包括电缆头上接头1、模具弹簧2、调整垫片3、内锥夹紧头4、外锥夹紧头5、锁紧块6，其特征在于：电缆头上接头1内置有模具弹簧2，模具弹簧2末端压调整垫片3，调整垫片3另一端压外锥夹紧头5，外锥夹紧头5外套着内锥夹紧头4，内锥夹紧头4末端压着锁紧块6，锁紧块6与电缆头上接头1螺纹连接。金属护套探测电缆依次穿过电缆头上接头1、模具弹簧2、调整垫片3、内锥夹紧头4、外锥夹紧头5、锁紧块6后，旋紧锁紧块6，使得内外锥夹紧头夹紧金属护套探测电缆，模具弹簧2产生弹性形变，模具弹簧2不同弹性形变量通过调整垫片3调节，对应不同的预设力值，当张力超过预设力值，则模具弹簧2继续产生弹性形变，使得外锥夹紧头5产生轴向位移，与内锥夹紧头4脱离，从而电缆可顺利脱开。
