Abstract
The utility model aims to provide a pipe sleeve insulator with simple structure and low processing cost. The pipe sleeve insulator comprises a columnar insulation main body and a current conducting rod, wherein a through hole is formed at the axle center of the columnar insulation main body; the current conducting rod is positioned in the through hole of the columnar insulation main body; external threads are formed at the two ends of the current conducting rod which extends out of the two ends of the columnar insulation main body; and nuts matched with the external threads are mounted at two ends of the current conducting rod. Compared with the present one, the pipe sleeve insulator provided by the utility model has simple structure, greatly improved processing efficiency, and lowered processing cost since two bolts are reduced and the through hole of the columnar insulator is not needed to be processed into a threaded hole.
Description
Technical field
The utility model relates to a kind of electric insulator, especially a kind of pipe box insulator.
Background technology
Realize by post insulator that in the insulation of motor train unit current transformer internal electric post insulator is to be used for supporting and fixing naked current, and make naked current and ground insulation or make mutually insulated between the current that is in different potentials.Post insulator comprises the column insulating body, and the needs during according to use can have screwed hole on the end face of column insulating body, and the screwed hole internal thread is connected with screw rod.But can not realize conducting function between the two ends of post insulator.
At the problems referred to above, a kind of pipe box insulator is arranged at present, comprise the column insulating body, have the screwed hole that communicates with its two ends at the place, axle center of column insulating body, the screwed hole internal fixation has contact rod, and the screwed hole two ends all are screwed with the set bolt that contacts with contact rod.Though this pipe box insulator has solved the shortcoming that the two ends of post insulator can not be conducted electricity, its structure and processing are all comparatively complicated, the cost height.
The utility model content
The purpose of this utility model provides a kind of simple in structure, pipe box insulator that processing cost is low.
Realize the pipe box insulator of the utility model purpose, comprise column insulating body and contact rod, the place, axle center of described column insulating body has a through hole, described contact rod is positioned at the through hole of described column insulating body, two ends are provided with external screw thread, stretch out the two ends of described column insulating body, the nut that matches with its external screw thread is equipped with at described contact rod two ends.
Preferably, described column insulating body is made by epoxy resin.
Preferably, described contact rod is made of copper.
Preferably, described contact rod two ends are provided with sealing ring.Prevent column insulating body through hole stored moisture content.
Advantage of the present utility model is:
Compare with existing pipe box insulator and to have reduced by two bolts, and through hole that will post insulator makes screwed hole, therefore simple in structure, working (machining) efficiency is provided greatly, reduced processing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model pipe box insulator.
Fig. 2 is the right view of Fig. 1.
Embodiment
As shown in Figure 1, 2, the pipe box insulator of the utility model specific embodiment, comprise column insulating body 1 and contact rod 2, the place, axle center of described column insulating body 1 has a through hole, described contact rod 2 is positioned at the through hole of described column insulating body 1, two ends are provided with external screw thread, stretch out the two ends of described column insulating body 1, and the nut 3 that matches with its external screw thread is equipped with at described contact rod 2 two ends.Described column insulating body 1 is made by epoxy resin.Described contact rod 2 is made of copper.Described contact rod 2 two ends are provided with sealing ring 4, prevent column insulating body through hole stored moisture content.
Pipe box insulator of the present utility model is compared with existing pipe box insulator and reduced by two bolts, and through hole that will post insulator makes screwed hole, and is therefore simple in structure, and working (machining) efficiency is provided greatly, reduced processing cost.
