Description
Technical field
The utility model relates to a kind of livewire work crowbar switch.
Background technique
Fastly divide and close fastly the lead-out wire of static contact side of crowbar switch in use, in the case where reversed torsion, root
Portion is easily broken off, and is repaired and needed fastly to divide and close fastly the static contact side of crowbar switch all to remove, and can be replaced.Electrification is made
Industry personnel operate under conditions of wearing insulation handle sleeve, large labor intensity.
When needing connection to divide fastly fastly close crowbar switch, livewire work personnel wear insulating glove, first fastly will divide and close fastly extinguishing arc
Switch be fixed on conducting wire by insulating cord, reuse spanner by wire clamp by static contact side lead-out wire be connected to live wire with
On lead, lead-out wire is the multiply annealed copper wire of transparent plastic crust.It has the disadvantages that
(1) lead-out wire of the multiply annealed copper wire of transparent plastic crust, after repeated use, be easy to cause in root it is stranded,
Influence electric current handling capacity；
(2) it needs just to can be carried out replacement after crowbar switch is all disintegrated when replacing lead-out wire；
(3) livewire work personnel need to operate using spanner in assembling and disassembling lead, due to wearing insulating glove behaviour
Make, large labor intensity.
Utility model content
The purpose of this utility model is to provide a kind of livewire work crowbar switch.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of livewire work crowbar switch, including being arranged in outside the arc extinguishing storehouse for dividing fastly fastly close the static contact side of crowbar switch
Plug-in handle, in plug-in handle setting for automatically clamp conducting wire component, component include metal fixed part and activity
Tongue, metal fixed part are connect with static contact, support top spring are provided between active tongue and plug-in handle, active tongue is in support top
It is contacted under the action of spring with metal fixed part.
The utility model, which further improves, to be, is provided in active tongue and metal fixed part contact position for pressing from both sides
Hold the groove of conducting wire.
The utility model, which further improves, to be, groove is arc.
The utility model, which further improves, to be, metal fixed part is connect by soft copper conducting wire with static contact.
The utility model, which further improves, to be, active tongue is duck tongue shaped.
The utility model, which further improves, to be, when connecting wire, is hung on conducting wire by plug-in handle, is being divided fastly
Under the fast gravity for closing crowbar switch, conducting wire squeezes active tongue, in the groove between metal fixed part and active tongue,
Active tongue clamps conducting wire under the support top effect of support top spring.
Compared with prior art, the utility model has the advantages that
The utility model is increased by installing plug-in handle additional outside the arc extinguishing storehouse for the static contact side for dividing fastly fastly close crowbar switch
Fastly divide and close fastly crowbar switch to be mounted on the position on conducting wire；Setting for clamping the component of conducting wire, portion automatically in plug-in handle
Part includes metal fixed part and active tongue, and metal fixed part is connect with static contact, is set between active tongue and plug-in handle
It is equipped with support top spring, active tongue contacts under the action of support top spring with metal fixed part.When divide fastly fastly close crowbar switch hang
When on conducting wire, by livewire work, personnel exert oneself, and conducting wire is squeezed between contact point and active tongue, make to divide fastly fastly close extinguishing arc to open
The static contact of pass is connected to the conducting wire of electrification.The utility model can be reduced since reversed torsion causes transparent plastic strand copper wire
Stranded hidden danger；Shorten the electrification activity duration；Reduce livewire work personnel labor intensity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 is plug-in handle, and 2 be support top spring, and 3 be active tongue, and 4 be contact point, and 5 be conducting wire.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
Referring to Fig. 1, plug-in handle 1 is installed in the utility model additional outside the arc extinguishing storehouse of static contact side, increase, which divides fastly fastly closes, to disappear
Arc switchs the position being mounted on conducting wire；
Contact point 4 is set in plug-in handle 1, and contact point 4 is connect by annealed copper wire with static contact, is played conducting electric current and is made
With setting active tongue 3 passes through 2 support top active tongue 3 of support top spring and squeezes contact point 4；
When dividing fastly fastly closing crowbar switch to hang on conducting wire, by livewire work, personnel exert oneself, and conducting wire is squeezed into contact point 4
Between active tongue 3, it is connected to the static contact for dividing fastly fastly close crowbar switch with the conducting wire 5 of electrification.
To divide fastly fastly close based on crowbar switch, static contact side lead-out wire is improved, fixed clamp type is changed to by wire type.I.e.
On the outside of the arc extinguishing storehouse of crowbar switch static contact position, plug-in handle 1 is installed additional, be provided in plug-in handle 1 for pressing from both sides automatically
The component of conducting wire is held, component includes metal fixed part and active tongue 3, and metal fixed part is connected by soft copper conducting wire and static contact
It connects, arc groove is set in active tongue 3 (duck tongue) and fixed part contact position, convenient for clamping conducting wire, in active tongue and handle
Between install additional support top spring, make active tongue 3 under the action of formulating spring, with fixed part be in close contact, when need connection lead
When line, by dividing fastly fastly closing the plug-in handle 1 of crowbar switch to hang on conducting wire, under the gravity of crowbar switch, conducting wire is squeezed
Active tongue 3 is opened, in the groove between fixed part and active tongue 3, makes active tongue 3 under the support top effect of support top spring 2
Clamp conducting wire.
The utility model is closed by 2 support top active tongue 3 of support top spring with contact point 4, and crowbar switch handle is divided fastly fastly close,
It solves the problems, such as to divide fastly fastly close crowbar switch static contact side lead-out wire to be easy stranded, reduces the labor that livewire work personnel install lead
Fatigue resistance.
