Abstract
A heavy current clamp belongs to the field of techniques. Original grounding clamps are inconvenient in usage. When space in a switch cabinet is small, ground wire clamps can not clamp leading-out aluminum bars on one sides of mutual inductors. The heavy current clamp of the utility model is characterized in that the heavy current clamp comprises a left clamp body, a right clamp body and a clamping body. The left clamp body and the right clamp body are in movable connection to form jaws through a pressure spring. The opposite jaws of the left clamp body and the right clamp body are provided with conductive members. The conductive members are connected with the left clamp body and the right clamp body through fasteners. The conductive member positioned on the inner side portion of the left clamp body is bent towards the left and then extends backwards to form an electricity access portion on the outer side portion of the left clamp body. Two support columns are arranged between the left side surface of the left clamp body and the right side surface of the conductive member electricity access portion. The clamping body comprises a clamping seat and a clamping member which can move towards the left and the right in the clamping seat. The clamping sear is connected with a power line. The clamping member moves and enables the electricity access portion to be clamped between the clamping member and the clamping seat. The heavy current clamp of the technical scheme is small in size, flexible in usage, and can be used in a cabinet with relatively small inner space. The usage scope is enlarged and the usage is convenient.

A kind of large electric current clamp, it is characterized in that: comprise left caliper, right caliper body and cramping body, left caliper and right caliper body are flexibly connected and are formed jaw by compression spring, and the jaw that left caliper is relative with right caliper body is provided with electric-conductor, and electric-conductor is connected with left and right caliper by securing member; The electric-conductor that is positioned at left caliper inner side bends left after backward and extends to form the electric access section that is positioned at left caliper outside, between the right flank of the left surface of left caliper and the electric access section of electric-conductor, establishes two support columns; Described cramping body comprises holder, folder that can side-to-side movement in holder, described holder connecting power line, and folder moves electric access section is clipped between folder and holder.The technical program volume is little, uses flexibly, in the cabinet in less space, also can use, and has expanded the scope of application; Easy to use.
As the further of such scheme improved and supplemented, the present invention also comprises following additional technical feature:
Described two ends, holder left and right are upwards extended and are formed respectively fixed part, clamping part; In described fixed part, offer screw, an adjusting screw(rod) and screw match, and the right-hand member of adjusting screw(rod) is established circular chuck; The left end of described adjusting screw(rod) is provided with operating grip; The width of described clamping part is less than the distance between two support columns; Clamping part can insert between two support columns, and the described electricity portion of connecing is positioned between chuck and clamping part; Described adjusting screw(rod), chuck, operating grip form folder; Described fixed part connecting power line.
Described left caliper and the jaw of right caliper body are equipped with the first protuberance and second protuberance of semicircle shape, and two first protuberances are relative, and two second protuberances are relative.Improve chucking power, also the convenient clamping to appointment place.
Described electric-conductor is copper bar, and the copper bar being positioned on left caliper and right caliper body is electrically connected by copper cash.
Copper bar outer surface is established tin coating.Can improve the conductivity of both contact positions, avoid partial discharge.
Beneficial effect: the technical program volume is little, uses flexibly, in the cabinet in less space, also can use, and has expanded the scope of application; Easy to use.
