Description
Technical field
The utility model relates to binding post, relates in particular to a kind of closed threephase cable binding post.
Background technology
In electric power system, often can relate to being connected between circuit and electric equipment; or the connection between circuit; especially being connected mostly between threephase cable and electric equipment and circuit connects by binding post; traditional binding post is to be provided with conductive plate in one end of body; power circuit is inserted in tube chamber; with hydraulic tongs, wire barrel is flattened to fastening cable; but this binding post must be used professional equipment in use; cost is relatively high; and need certain operation skill, be unfavorable for removing and installing simultaneously.In addition, the intensity of these binding posts is lower, the series of problems such as the resistance to property pullled is weak, contact area is little, contact resistance is large, electric energy loss is serious, especially the general diameter of threephase cable more greatly when being fixedly connected with existing terminal not firmly, long-play easily comes off, loose contact, the particularly cross-over connection of long distance, running current is very large, in the moment of opening operation, produce vibrations, can make jumper get loose, there is cable collapsing and burning accident in electric field electric discharge, need to often keep in repair, and has certain potential safety hazard.
Utility model content
The utility model is intended to for the deficiency existing in background technology, and a kind of closed threephase cable binding post providing.
Closed threephase cable binding post of the present utility model, by insulator foot, insulating pad and cord grip form, directly over the both sides of described insulator foot, be equipped with protruding seamed edge, the top of insulator foot is equipped with insulating pad, on insulating pad upper surface, be interval with about three parallel grooves that connect, in each groove, be all equipped with metallic conductor, the upper surface of described metallic conductor is provided with the circular arc conduit that left and right connects, circular arc conduit and corresponding groove are provided with the square through hole of plural longitudinal perforation, on the corresponding insulator foot of each square through hole, be equipped with bolt hole, described cord grip is to have welded screw rod formation in circular sleeve transverse lower portion, screw rod is through square through hole, insulating pad and insulator foot, the circular sleeve on cord grip top coordinates with square through hole, the screw rod of bottom is connected with nut screw socket.
As further improvement of the utility model, the both sides on described circular sleeve top are equipped with extension.
As further improvement of the utility model, a side gemel connection of described insulating pad safe buckle closure.
Closed threephase cable binding post of the present utility model, structural design is exquisite, is particularly useful for using in the connection of thicker threephase cable, stability is strong, difficult drop-off, be convenient to dismounting, contact resistance is little, electric energy loss is low, maintenance cycle is long, and security performance is high, reduces maintenance cost.This device, by the groove with corresponding with cable list core cross section radian, makes cable sleeping therein, enlarge active surface when tightly clamping, and be furnished with exterior insulation shell, and can effectively prevent phase fault, make it stable.
