Abstract
The utility model relates to short-circuit grounding wire for circuits, which is suitable for current interruption maintenance work for high-voltage circuits and is composed of a chieftain assembly, an insulating rod, a wire nose, a soft hinging protective sleeve wire, a connecting pipe and a grounding rod. The utility model is characterized in that the chieftain assembly is a mechanical structure and comprises a left screw rod, a top rod, a channel activating turning board, and a bracket, the left screw rod and the top rod are in screwed connection, and the top rod and the channel activating turning board are connected by a pin. The channel activating turning board is locked by a round head bolt on the bracket. The bracket is clamped and buckled on an annular groove of a neck part of the left screw rod through the round head bolt. The bracket is made to rotate im 360 DEG in a horizontal direction. A backbone of the bracket is provided with a connecting board and a hoop buckle. The end of the connecting board is provided with a circuit board. In this way, when the utility model is used, after a connected wire nose is fixedly installed on the circuit board, the insulating rod is held by a hand and is rotated horizontally. The left screw rod is driven for rotation. The channel activating turning board is fully opened or contracted tightly. The reliability and the safety of grasping a lead can be effectively enhanced.
Description
One, technical field
The utility model relates to a kind of earth connection line clamping device, a kind of circuit short-circuit grounding wire that uses when being applicable to the operation of high-tension circuit interruption maintenance.
Two, background technology
Existing composite type short-circuit grounding wire, mostly adopt double-spring type conductor wire end wire clamp knot, the clamping connection principle mainly adopts clamping plate spring (being commonly called as two-man act) and lock and clamp clip to have an effect, and buckles on the circuit during work and grips on circuit, work finishes and up promotes, and lead skids off the two-man act clamping plate.Chuck adopts aluminum alloy materials hook fixed structure, distinguishes with two-man act and circuit with copper to be connected the direct crimping of line nose and earth connection, the soft sheath of overcoat.But have following problem: 1, to special line footpath (more slightly or thinner), the firm degree of its two-man act sheet is not high, easily slippage or can't clip; 2, line nose and earth connection joint fastness, fail safe are not strong; 3, aluminium alloy clamping head material electric conductivity is good inadequately.
Three, summary of the invention
Problem to be solved in the utility model is: changing the two-man act intermediate plate is mechanical type chieftain structure, by rotating left-handed screw, the promotion push rod opens active turnover panel or tightens up, and online nose and earth connection junction are provided with hoop button and tension disc, thereby improve the reliability that earth connection is connected with lead effectively.
Its technical scheme is: by chieftain's assembly, insulating rod, the line nose, soft strand RVV, tube connector and earth rod constitute, chieftain's assembly is installed in the insulating rod top, the line nose is connected with earth rod by soft strand RVV and tube connector, it is characterized in that chieftain's assembly is a mechanical type member, it includes: left-handed screw, snap bolt, support, push rod, active turnover panel and hold-down nut, spiral is connected between left-handed screw and the push rod, the push rod other end is connected with active turnover panel, active turnover panel is rack-mount by snap bolt, support partly is wrapped in the connecting portion of push rod and left-handed screw, and be buckled in by snap bolt on the neck annular groove of left-handed screw, be provided with hoop button and connecting plate at support back face, connecting plate is provided with tension disc, and the line nose is withheld to be buckled on the connecting plate by tension disc and hoop and is fixed on the support by set bolt.
Its beneficial effect because of adopting a kind of mechanical type chieftain structure, by rotating left-handed screw, opens active turnover panel effectively or tightens up, and can adapt to not that the lead in collinear footpath uses, and is difficult for slippage, fastness, reliability height; In addition, line nose and earth connection junction are provided with hoop and buckle and tension disc, can guarantee that like this earth connection is firmly attached on chieftain's assembly.
