Abstract
The utility model provides a jaw type clamp grounding wire, relates to a grounding wire device for electric power maintenance, and has the advantages of handiness in operation, reliable connection and small occupied area. A pair of clamp arms is provided; the clamp arms comprise jaws made of conductive materials and clamp handles made of insulating materials; a grounding wire is connected with the outer side of the jaw of one of the clamp arms; and a pressure spring is arranged between the two clamp arms. In the utility model, a short and powerful clamp is utilized for directly clamp a bus bar, so that the operation is very convenient; and the pressure spring arranged between the two clamp arms is used for a certain clamping firmness. The utility model provides a means that a jacking rod is arranged at the lower end of one clamp handle, after a preliminary clamping connection, by folding the jacking rod and utilizing the jacking pressure f applied by the jacking rod between the two clamp arms, greater clamping force F of the jaws on the top is achieved; and certainly, whether a sliding sleeve is added at the hinging part or not for relatively fixing the jacking rod and one handle root when the jacking rod is not folded can depend on a technical personnel in the field to implement.
Description
Technical field
The utility model relates to a kind of grounding wire device of electric power maintenance usefulness.
Background technology
The installing earth connection can prevent that incoming call is " life support umbilical " of the electric personnel's work safety of protection to the injury of the person suddenly.Hanging earthing conductor is important technical safety measures of electrical installation, its operating process should be strictly, conscientious, meet demand of technical standard, ten million careless It should never be treated in an off-handed manner.Therefore, must correctly use the earth connection that meets field apparatus requirement and operational environment, and standard ground hangs, tears open, could avoid the generation of personal electric shock casualty accident effectively.
At present, when the installing earth connection, the two whip graft heads of general using long insulating handle operation are articulated in ground wire on the low-voltage bus bar row.On the one hand, this mode needs bigger operating space, because the insulation handle is longer, the chamber door of casing can't be closed; On the other hand, this mode of operation connection is not firm, operation is not nimble, makes operating efficiency extremely low, and attaching is second-rate.
The utility model content
The utility model provides a kind of jaw formula chuck earth connection nimble, that connect reliably, take up room little of operating at above problem.
The technical solution of the utility model is: a pair of tong arm is arranged, and tong arm comprises the pincers handle that the jaw made by electric conducting material and insulating material are made, and wherein the jaw of the tong arm outside is connected with earth connection, is provided with stage clip between two tong arms.
The clamping surface of described jaw is the plane.
The pincers handle of arbitrary tong arm is that described wrap direction is towards another tong arm by tang and the hinged bendable structure that forms of push rod in the described a pair of tong arm.
Described another tong arm inboard is provided with the holding groove that is used to hold described push rod termination; Described push rod end face is an arcwall face.
Described holding groove groove bottom is a matsurface.
The arcwall face of described push rod end face is a matsurface.
The utility model utilizes short and small, strong clamp, directly is clipped on the bus row, and it is very convenient to operate; Have certain firmness for making to clamp, between two tong arms, be provided with a stage clip.In addition, when clamp, for preventing " flashover ", the working face of jaw is the plane preferably, and past people is for increasing frictional force, clamping force, total custom jaw is set to serrated face, we find that in test " sparking " (" flashover ") phenomenon can appear in this on bus " multiple spot contact " pattern, and the face contact can overcome this phenomenon, therefore jaw of the present utility model is made as the plane, contacts with maintenance face between the bus row.At last, clamping force also can influence quality of connection, sometimes, only relies on stage clip, and the firmness of connection is also not high; Therefore, the utility model proposes the means that a push rod is set in pincers handle lower end, behind preliminary clamping connection,, utilize the top power f of push rod between two arms to make the clamping force F of upper end jaw higher by the bending push rod; Certainly, whether increase a sliding sleeve,, can select to implement by those skilled in the art with push rod and tang relative fixed when the not bending in hinge point.

Embodiment
The utility model has a pair of tong arm as shown in Figure 1, and tong arm comprises the pincers handle 7 that the jaw 2 made by electric conducting material and insulating material are made, and wherein jaw 2 outsides of a tong arm 7 are connected with earth connection 8, are provided with stage clip 3 between two tong arms.For making between jaw 2 and the bus row 1 to face contacts, to avoid " sparking ", the clamping surface of jaw 2 is the plane.
On the previous embodiment basis, for making the clamping force F between jaw 2 and the bus row 1 bigger, another embodiment of the present utility model as shown in Figure 2, the pincers handle 7 of arbitrary tong arm is for by tang 4 and the push rod 6 hinged bendable structures that form in a pair of tong arm, described wrap direction is towards another tong arm.The hinge pin 5 that is articulated and connected should be parallel with bus row 1 longitudinal axis.Another tong arm inboard is provided with the holding groove 9 that is used to hold described push rod 6 terminations; Described push rod 6 end faces are arcwall face.
For making between push rod 6 and the holding groove 9 apical grafting reliable, holding groove 9 groove bottom are matsurface.The arcwall face of push rod 6 end faces is a matsurface.
In addition, for adapting to the bus row of different-thickness, tang 4 and jaw 2 connecting portions can be kept a splaying 10, to regulate.During screw-in, gap 10 diminishes, and working size becomes big between the jaw 2, adapts to thicker bus row 1; Otherwise, adapt to thin bus row.Simultaneously, wearing and tearing, the distortion of the holding groove on the push rod that can also make insulating material of this gap 10, push rod opposite compensate.Like this, just can guarantee that push rod 6 is relative consistent with the active force f between the holding groove 9.
