The mode that place is operated, such working method often consumes the unnecessary time, or even brings operating risk.Such as after
Electric protection maintenance repair work in, staff need to obtain control loop terminal open into output information.Because device
Display screen is in screen cabinet front, and connecting terminal, so staff needs to operate at the screen cabinet back side, then arrives again at the screen cabinet back side
Shield cabinet positive confirmation information.Movement so repeatedly consumes a large amount of time, both affects working efficiency, and repeatedly into
The same operation of row easily causes nerve numb, increases the risk for accidentally touching false protection caused by mis-wired.
In addition to this, when doing the C-V characteristic of 10kV route CT, because every CT at least has protection, measurement, metering 3
A winding, each winding will do C-V characteristic respectively, therefore, each line work personnel at least be needed to arrive for 3 times
Thread-changing at the connecting terminal of switchgear lower rear.In transformer substation high voltage chamber, general switchgear back side light is dark, and connects
Narrow space at line terminals, each time thread-changing require staff and squat down body, differentiate in very little light each
A connecting terminal.It works under such circumstances, the serious progress for affecting work, and staff is be easy to cause to damage
Gouge is unfavorable for the development of work.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, and to provide a kind of for secondary device test connection

Line post terminals are mainly used for of short duration signal measurement or short circuit, and staff is facilitated to operate.
The wiring post terminals are equipped with plastics inserted sheet and are isolated, and prevent from accidentally touching.
Insulation silica gel is equipped between experiment terminal and each terminal of operation terminal to be isolated.
It is isolated between each terminal by insulation barrier inside the terminal box, it is external also by insulation silica gel isolation, insulation
Property good, the problems such as there is no short circuits, ground connection.Wiring post terminals above terminal box are isolated by plastics inserted sheet, prevent from accidentally touching, peace
It is complete reliable.
The connecting terminal of experimental provision in use, is led to the experiment terminal of experiment terminal box by the utility model terminal box
Place, if necessary, can disposably draw 12（6 pairs）Then experiment terminal box is moved to staff again and facilitates work by terminal
Place.Staff pair of wire connection terminals can just operate at corresponding operation terminal in this way.12 operations of the device
Terminal is that jack type and wiring pillar use jack type terminal, can guarantee connect in this way if open into or output for a long time
Line is stable and firm；If carrying out of short duration signal measurement or short circuit, plastics inserted sheet is pushed aside, using wiring post terminals, in this way
Staff can be facilitated to operate.Plastics inserted sheet is reversed again after work, plays the role of isolation, prevents from accidentally touching.
The utility model terminal box, small in size, light-weight, conveniently moving can be according to any movement of needs of job site.
Its is widely used, insulation is reliable, easy to operate, at low cost.The terminal box is by leading to work for the connecting terminal of secondary device
Personnel facilitate the place of work, on the one hand avoid the same operation bring nerve numb of the carry out of staff repeatedly, and lead
Cause occurs accidentally touching the generation that mis-wired causes false protection phenomenon during searching connecting terminal, on the other hand disposably draws
Working efficiency can be improved in multipair terminal, and the personal safety of staff has also been ensured while improving working environment.
