Abstract
It is moved the utility model relates to a kind of detachable and becomes high tension terminal, in order to solved existing move between the pedestal and insulator that become high tension terminal and be connected, be can not be split, the technical problem that maintenance difficulties are big, at high cost by the way of fixed.The utility model includes insulator, tension disc, wiring screw rod and expansion pin；One end of the insulator is equipped with disconnecting link terminals, and the other end is equipped with threaded conductive bar, and the middle and lower part of the threaded conductive bar is equipped with pin hole；The threaded conductive bar of insulator is located in the threaded hole among tension disc, and the expansion pin passes sequentially through the expansion pin hole on tension disc and the pin hole on threaded conductive bar and fixed tension disc, the wiring screw rod are located in the screw hole of tension disc two sides.The utility model structure is simple, can flexibly dismount, and when screw thread, which occurs, in the wiring screw rod of binding post smoothes out with the fingers button, can directly disassemble tension disc from insulator, then replace wiring screw rod, reduce the maintenance cost of binding post, utility value with higher.
Description
Technical field
The utility model belongs to transformer technology field, and in particular to a kind of detachable shifting change high tension terminal.
Background technique
In recent years, as China's fully-mechanized mining working and exploitation dynamics are gradually increased, the utilization rate of electrical equipment is significantly
It improves, phase shifting transformer is particularly important as the substation of the main power supply and distribution of fully-mechanized mining working.However phase shifting transformer high pressure is protected
Protecting box load binding post is easily damaged in use, one is binding post underground using when wiring, take out stitches more frequently,
The second is the line footpath of the connect power supply line of binding post is thicker, cause the screw buckle stress on tension disc and wiring screw rod larger, when long
Between will cause screw buckle and smooth out with the fingers button phenomenon, cause screw buckle to fall off, crimping is not tight, causes the failures such as power supply virtual connection, overheat, short circuit
Occur, not only influences the service life of equipment, also cause great electrical hidden danger to produced on-site.
Existing move between the pedestal and insulator that become high tension terminal is connected by the way of fixed, be can not be split, is connect
In use Yi Dan screw thread occur and smoothed out with the fingers button, entire binding post can not just reuse terminal, be equivalent to disposable product,
It can not repair, need when replacement integrally to dismantle from guard box, maintenance difficulties are big, at high cost.
Utility model content
Purpose of the utility model is to solve existing move between the pedestal and insulator that become high tension terminal to use
The technical problem that fixed mode is connected, be can not be split, maintenance difficulties are big, at high cost provides a kind of shifting of detachable and gets higher pressure
Binding post.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of detachable shifting change high tension terminal, including insulator, tension disc, wiring screw rod and expansion pin；The insulation
One end of son is equipped with disconnecting link terminals, and the other end is equipped with threaded conductive bar, and the middle and lower part of the threaded conductive bar is equipped with pin hole；Institute
It states and is equipped with threaded hole among the upper surface of tension disc, the two sides of the threaded hole are symmetrically arranged with screw hole, the side of the tension disc
Face is equipped with expansion pin hole, and the threaded hole among the expansion pin hole and tension disc is connected；The threaded conductive bar of the insulator is located at
In threaded hole among tension disc, the expansion pin passes sequentially through the expansion pin hole on tension disc and the pin hole on threaded conductive bar and consolidates
Constant-pressure line plate, the wiring screw rod are located in the screw hole of tension disc two sides.
It the beneficial effects of the utility model are: the utility model structure is simple, can flexibly dismount, be fixed using expansion pin absolutely
The tension disc of edge and binding post can be directly by tension disc from insulation when screw thread, which occurs, in the wiring screw rod of binding post smoothes out with the fingers button
It is disassembled on son, then replaces wiring screw rod, continued to come into operation after can thus replacing the binding post of damage, reduce
The maintenance cost of binding post, utility value with higher.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1-Figure 3, one of the present embodiment detachable, which moves, becomes high tension terminal, including insulator 1, crimping
Plate 2, wiring screw rod 3 and expansion pin 4；One end of the insulator 1 is equipped with disconnecting link terminals 101, and the other end is equipped with threaded conductive bar
102, the middle and lower part of the threaded conductive bar 102 is equipped with pin hole；Threaded hole 201, institute are equipped among the upper surface of the tension disc 2
The two sides for stating threaded hole 201 are symmetrically arranged with screw hole 202, and the side of the tension disc 2 is equipped with expansion pin hole 203, the expansion pin hole
203 are connected with the threaded hole 201 among tension disc 2；The threaded conductive bar 102 of the insulator 1 is located among tension disc 2
In threaded hole 201, the expansion pin 4 passes sequentially through the expansion pin hole 203 on tension disc 2 and the pin hole on threaded conductive bar 102 and consolidates
Constant-pressure line plate 2, the wiring screw rod 3 are located in the screw hole 202 of 2 two sides of tension disc.
