Description
Technical field
The present invention relates to electrical equipment technical field, in particular to a kind of cable head protection device.
Background technology
When secondary loop in power system carries out service work, in order to prevent service work from impacting other operational outfits, need secondary circuit to disconnect.Disconnecting secondary circuit is pulled down by secondary line cable the end of a thread on terminal board mostly.Because part secondary line cable the end of a thread is live wire, generally speaking, secondary line cable the end of a thread that these remove all needs to do insulation isolation processing.Although part secondary line cable the end of a thread is not charged, once encounter electrified body can cause adverse consequences.Therefore, it is most important that the secondary line cable the end of a thread these removed carries out insulation processing.In addition, for the working site of complexity, multiple loop may be had to need to do insulation measures.
At present, conventional insulating treatment method is wrapped on cable the end of a thread with insulating tape to wrap by the metal core that cable the end of a thread is exposed, can prevent people or other equipment from encountering like this and cause personal injury or electric network fault.
There is following problem in above-mentioned insulating treatment method:
One, be wound around insulating tape and may cause defective insulation due to the reason of staff's technical merit or sense of responsibility, real insulating effect can not be played.
Two, in the process with insulating tape wrap electric lead, human contact may be made to arrive electrified body due to careless manipulation, cause personal injury.
Three, Reusability insulating tape wrap electrical cables the end of a thread, easily leaves filth on metal core, causes metal core to connect reliability decrease when reusing, and loop may be caused to connect bad time serious.
Four, insulating tape uses rear not reproducible use, and every task all with new insulating tape, is wasted more.
Five, adopt in this way that operating efficiency is lower, need to spend the more time.
Six, when there being multiple loop to need to do insulation processing, may disperse due to place, process points is many, causes easily occurring omitting when last recovery, and then leads to a disaster.
Summary of the invention
The present invention aims to provide a kind of cable head protection device, to solve the not good problem of cable the end of a thread insulation effect of disassembling in prior art.
To achieve these goals, the invention provides a kind of cable head protection device, comprising: insulation locking cylinder, the two ends of insulation locking cylinder are open end, are provided with locking inner conical surface in insulation locking cylinder; Insulation accommodation tube, the first end of insulation accommodation tube is blind end, second end of insulation accommodation tube has the elastic portion coordinated with cable the end of a thread, wherein, insulation locking cylinder and insulation accommodation tube are removably connected, and insulation locking cylinder and the accommodation tube that insulate lock inner conical surface when being connected and support elastic portion elastic portion is fixed on cable the end of a thread.
Further, be threaded connection between insulation locking cylinder and insulation accommodation tube.
Further, insulation locking cylinder has shell of column and cone section, and the inner surface of cone section forms locking inner conical surface.
Further, elastic portion comprises multiple elastic card claws of the circumference setting along insulation accommodation tube.
Further, elastic card claw is three, and the circumference of three elastic card claw edge insulation accommodation tubes is uniformly distributed.
Further, the cross sectional shape of elastic card claw is arc-shaped.
Further, on the axis direction of insulation accommodation tube, the aperture of the through hole that the inner surface of multiple elastic card claw limits reduces from inside to outside gradually.
Further, the material of insulation locking cylinder and insulation accommodation tube is plastics.
Apply technical scheme of the present invention, first insulation locking jacket casing is located on the cable the end of a thread disassembled, then cable the end of a thread is inserted in insulation accommodation tube from the elastic portion being arranged on insulation accommodation tube second end, finally insulation locking cylinder and insulation accommodation tube is linked together.Owing to being provided with locking inner conical surface in insulation locking cylinder, when the locking cylinder that insulate is connected with insulation accommodation tube, locking inner conical surface supports elastic portion makes elastic portion be fixed on cable the end of a thread.Can prevent insulation locking cylinder and insulation accommodation tube from splitting away off from cable the end of a thread like this, like this, cable the end of a thread is contained in insulation accommodation tube, thus plays insulating effect, and then efficiently avoid operator and touch and the situation of causing danger, safe and reliable.After using, insulation can be made to lock cylinder and to be separated from each other with insulation accommodation tube, easy to use, can repeat to use, save cost.Technical scheme of the present invention also avoid because using the insulating tape reliability decrease that causes cable the end of a thread to be connected and loop to connect bad problem simultaneously.
