Embodiment 1
Short clip, including upper duckbilled 1 and lower duckbilled 2 are fixed in a kind of livewire work as shown in Figure 1, and upper duckbilled 1 is with
Formed between the dismounting connection of duckbilled 2, and upper duckbilled 1 and lower duckbilled 2 after connection two it is independent for fixing the short of short-circuit line
Line connects hole 6, and the inner side that short-term connects hole 6 is provided with insulating barrier 7；
The short-term that upper and lower duckbilled is formed after coupling together connects hole 6 can be fixed short-term, line when meeting line fault
The short circuit demand that road is normally run, it is to avoid in maintenance process, faulty line does not have short circuit, to operating personnel under livewire work
Potential safety hazard is caused, while the insulating barrier 7 being provided with avoids powered short-circuit line from discharging causes the injury of body to operating personnel, together
The situation of Shi Zaocheng great fire occurs, and upper duckbilled 1 and lower duckbilled 2 are attached by the way of dismounting, particularly,
Upper duckbilled 1 is taken apart with lower duckbilled 2 first when before installing, then upper duckbilled 1 is put between the short-term for needing fixation, so
Lower duckbilled 2 on duckbilled 1, is realized to the short circuit demand between short-term on being fixedly installed to afterwards.
Particularly upper duckbilled 1 is suspended on main electrical scheme, then lower duckbilled 2 is installed on upper duckbilled 1, but it is not complete
Complete fixed, connect in hole 6 one is used to hang main line two short-terms, it is to avoid need people to be affectedly bashful whole short clip, compared with
Manpower is lacked, has then been allowed two with short-term and put into during another short-term connects hole 6, finally lower duckbilled 2 has been completely fixed and is installed to
On upper duckbilled 1, it is ensured that firm contact reliability, the short circuit demand that circuit normally runs when meeting line fault is simple to operate, is easy to
Suspension, it is firm to fasten, highly reliable；For the work of staff provides guarantee, it is to avoid the safety that hot line job brings is hidden
Suffer from, while effectively raising the overhaul efficiency of failure.
Embodiment 2
On the basis of embodiment 1, the fixed dismounting of upper and lower duckbilled, is provided with duck under insertion on lower duckbilled 2 for convenience
First screwed hole 3 of mouth 2, upper duckbilled 1 is provided with and corresponding second screwed hole 5 of the first screwed hole 3, upper duckbilled 1 and lower duckbilled 2
Connection is dismounted by the bolt 4 being through on the second screwed hole 5 and the first screwed hole 3.During installation, it is only necessary to by bolt
4 be tightened in the first screwed hole 3 and the second screwed hole 4 by, it is necessary to when dismantling, bolt 4 be unclamped, duckbilled 1 is with in completion
The dismantlement work of duckbilled 2.
Two the 3rd screwed holes 202 are additionally provided with lower duckbilled 2, and two screwed holes 202 are located at the first screwed hole 3 respectively
The left and right sides, be connected with a fastening bolt 203 on each the 3rd screwed hole 202.The fastening bolt 203 is mainly used in solid
Main line and short-term that short-term connect in hole 6 is scheduled on to be fixed, it is as shown in Figure 1 first such as when fixed to hang over upper duckbilled 1
On main line (wire of short-term does not occur), the short-term that main line hangs the left side in Fig. 1 connects hole 6, then passes through lower duckbilled 2
On bolt 4 on upper duckbilled 1, not fully tighten, then will be connect the short-term that main line is fixed on the left side by fastening bolt 203
In hole 6, the suspension to fixed short clip is fully achieved, during the short-term that short-term puts into the right is then connect hole 6 again, by the right side
Be fixed for short-term by the trip bolt 203 on side, then again tightens bolt 4, complete short-term short circuit, patent in order to
Two short-terms are completed while the purpose of short circuit, the lower duckbilled 2 for being used is two, is fixed to upper duckbilled 1 by bolt 4 side by side
On, particularly, after a short-term is fastened by fastening bolt 203 first, then another needs are carried out
The short-term of short circuit is fixed on another lower duckbilled 2 by the fastening bolt of back, realizes two purposes of shorting stub short circuit.
Further, in order to guarantee short-term is completely carried out short circuit to live, and ensure that the two of short circuit will not with line
Fall off, while shorting stub will not come in contact with main line, it is two roundlet arc flutings in the inner surface of upper duckbilled 1
101, and two arc grooves 101 raised 8 are separated by what the medial surface of upper duckbilled 1 middle part was provided with；On the inner surface of lower duckbilled 2
A great circle arc fluting 201 is provided with, short-circuit string holes 5 is to be fastened to form by roundlet arc fluting 101 and great circle arc fluting 201.Big roundlet
The cooperation of arc fluting can carry out firm fixation to short-term, and will not make short circuit and deform, and effectively raise tight
Gu strong degree, reliability.
Further, it is fixed to ensure what shorting stub can be more firm, in insulating barrier 7 is mutually interconnected by multiple
The insulation tooth composition for connecing, and the insulating barrier 7 of insulation tooth composition is fixedly installed on the inner side that short-term connects hole 6.
In order to ensure the safety of maintainer, it is to avoid situation about leaking electricity occurs, and is surface in short clip
It is each coated with insulated paint.
Embodiment 3
On the basis of embodiment 2, a fastener for being used to tighten bolt is also included as shown in Figure 2, the fastener includes
