Abstract
The utility model discloses a special clamp for secondary wire connecting. The special clamp for secondary wire connecting comprises a rotating shaft, clamp rods and insulated clamp handles. The terminals of the clamp rods are provided with channel sections, the exterior of the rotating shaft is provided with an insulation sleeve, and the exterior of each clamp rod is provided with an insulated rubber layer. According to the utility model, the clamp is improved based on nipper pliers, the structure of the clamp body is similar to the structure of common nipper pliers, steel material is employed for a skeleton, while the terminals of the clamp rods are provided with channel sections for clamping a secondary wire, the clamp handles, the clamp rods and the rotating shaft all possess insulating properties, and the special clamp is suitable for live-line work.
Description
Technical field
The utility model relates to a kind of electric operating instrument, is specifically related to the secondary connection pincers of using in a kind of electric power system.
Background technology
When being engaged in electric power system two tasks, tear, connect very difficulty of secondary line open, do not have electric the time difficulty also relatively little, when charged the time, quite bother.Reason has a lot: arrange such as staggered floor before and after the terminal board; All connect good several threads on each terminal, needed to remove or increase by one; Cable is too much, is not enough to down finger with the space of terminal board; Various relays are arranged closely, are not enough to down finger or the like apart from the space.Run into this situation, the operator can adopt aids such as pliers.If install charged or core and terminals of adjacent charged, then can only adopt nipper pliers to twine insulating tape and disconnect.There is following shortcoming in this: 1, bad winding, because the more past mouth mouth of nipper pliers place taper more, rotating shaft place can't be twined insulation, because once twining the bad folding of adhesive plaster, causing it is not all insulation; 2, nipper pliers just presss from both sides not stringing easily in case twine to go up adhesive plaster, because its mouth mouth place is minimum, the end of a thread is very easily loosening, and mistake is bumped other terminal and the earthing of casing, and nipper pliers not insulated part also possibly run into shell and cause earth fault.
During protection work secondary connection,, cause electric power accidents such as DC earthing, false positive signal even mistake TRIP probably if the instrument improper use mistake occurs and bumps situation such as other live terminal, secondary line or device housings.
The utility model content
Chargedly during technical problem that the utility model will solve do not have special instrument when carrying out secondary connection, be prone to cause the accident, a kind of secondary connection special vice that carries out secondary connection that can be charged, safe is provided.
The technical scheme of the utility model realizes in the following manner: a kind of secondary connection special vice, comprise the pincers handle of rotating shaft, claw beam and insulation, and said claw beam termination is provided with draw-in groove, and said rotating shaft is outer to be provided with insulating case, and the outer mistake of said claw beam has been moulded the electro-insulating rubber layer.
The cross section of cell body is the shallow slick and sly groove of middle groove depth, two end slots in the said draw-in groove.
The utility model is on the basis of nipper pliers, to improve; Its caliper structure and common nipper pliers roughly the same, with steel material as skeleton, but in the utility model the claw beam termination be provided with draw-in groove in order to the chucking secondary line; And pincers handle, claw beam, rotating shaft all have insulation property, are suitable for live line working.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
Shown in accompanying drawing, a kind of secondary connection special vice comprises rotating shaft 2, claw beam 3 and the pincers handle 1 that insulate, and said claw beam 3 terminations are provided with draw-in groove 4, are arranged with insulating case in the said rotating shaft 2, and said claw beam 3 outer mistakes have been moulded the electro-insulating rubber layer.
The cross section of cell body is the shallow slick and sly groove of middle groove depth, two end slots in the said draw-in groove 4.Can clamp three kinds of common secondary lines commonly used like this: 1.5 mm
2, 2.5 mm
2With 4 mm
2, and these three kinds of model line can both cannot not clamp looseningly.Claw beam 3 is thinner than general nipper pliers in the utility model, can be adapted at operation in the small space like this.And the material of the electro-insulating rubber layer outside the claw beam 3 is identical with the rubber gloves material that the power worker uses always, can be used for the electrician's operation below the 1000V.
Claims (2)
1. secondary connection special vice; The pincers handle (1) that comprises rotating shaft (2), claw beam (3) and insulation; It is characterized in that: said claw beam (3) termination is provided with draw-in groove (4), the outer insulating case that is provided with of said rotating shaft (2), and outer mistake of said claw beam (3) moulded the electro-insulating rubber layer.
2. secondary connection special vice according to claim 1 is characterized in that: the cross section of cell body is the shallow slick and sly groove of middle groove depth, two end slots in the said draw-in groove (4).
