Abstract

本实用新型管接头是紧固、密封橡胶、塑料护套电缆的管接头。
本实用新型管接头是利用旋紧螺母压迫密封环,使密封环外锥圆沿着接头体内锥孔滑动,进而收紧封环内孔,从而紧固、密封橡胶塑料护套电缆外圆。起到防水、油、尘侵入,承受外界牵引力,保证电缆接线头安全的目的。

Description

一种橡胶塑料护套电缆管接头
本实用新型是紧固、密封橡胶、塑料护套电缆的管接头。
通常所用的橡胶、塑料护套电缆管接头是由接头体、密封环、螺母、密封圈、锁母组成。现有技术中接头体内孔是采用阶梯状圆柱形内孔,密封环是圆柱形圈。其缺点是螺母旋紧后,密封环内孔收缩量较小,而电缆外圆尺寸允许公差大于收缩量。要达到紧固、密封目的,必须备多个不同内径尺寸的密封环供选用。这样既增加了零件费用,又增加了安装使用的麻烦和时间。
本实用新型的目的是创造一种密封环内孔收缩量超过橡胶、塑料护套电缆外圆公差量的紧固、密封橡胶、塑料护套电缆管接头。
本实用新型管接头其特征是接头体的内孔是一个锥度为20°~40°的圆锥孔,密封环是一个外形与接头体内锥孔相匹配的带柱形内孔的锥形环。利用螺母压紧密封环,使密封环外锥圆沿着接头体锥形内孔滑动,进而收缩密封环内孔,从而达到紧固、密封橡胶、塑料护套电缆外圆。这种结构密封环内孔收缩量远超过电缆的公差量。完全能满足橡胶、塑料护套电缆外径尺寸的上、下限尺寸。並且完全能达到防水、油、尘的侵入,承受外界牵引力,保证电缆接线头安全。
本实用新型管接头的接头体,密封环也可制成在锥形大端接一圆柱形。密封环内孔壁也可制成二道或多道环形小凸肩以增加紧固力和密封性。
附图说明:
图1.橡胶、塑料护套电缆管接头剖视图。
图2.在锥形大端接一圆柱形的接头体及密封环剖视图。
图3.内孔壁带环形小凸肩的密封环剖视图。
图中,1螺母        2密封环        3接头体        4密封圈        5锁母        6橡胶、塑料护套电缆
本实用新型的橡胶、塑料护套管接头如图1所示,经实践证明如M18×1.5规格,螺纹接口尺寸为M18×1.5,密封环内孔通径为φ9,外圆为φ15.5,锥度为30°,接头体内孔锥度与密封环锥度相配。经试验旋紧螺母1后,φ6.5-φ9橡胶、塑料护套电缆都能达到紧固、密封目的。抗泄漏试验:水汽压力为每平方厘米2公斤,静置30分钟,无泄漏,压力表读数不下降;抗拔脱力试验>0.38千牛顿(约略大于38公斤)。
