2, coordinated with corresponding inner clip by conductor and install, the tightness according to coordinating adjusts, if the cross-sectional outer diameter of conductor is greater than the internal diameter of the inner clip fastened by semicircular ring, two of inner clip semicircular ring can be kept evenly to separate; If cross-sectional area of conductor external diameter is less than the internal diameter of the inner clip fastened by semicircular ring, one deck copper packing can be wrapped up on the surface of conductor, guarantee after installation is complete, the close contact of conductor and inner clip;
3, after two inner clips are coordinated installation with corresponding conductor, coordinate with outer clip and install; The uniform force of two parts up and down of inner clip is made in installation process;
4, mounting fastener in the through hole at outer clip two ends, and guarantee that conductor and wire clamp fully contact and fix.
Compared with the prior art, the beneficial effect that the present invention reaches is:
1, conductor fully contacts with wire clamp, and contact resistance is very little;
2, wire clamp adopts screw bolt and nut fastening, is connected firmly, can guarantees that conductor and fixture can not come off in use procedure;
3, be applicable to and be connected with the conductor of different cross section;
4, structure is simple, mounts and dismounts convenient and swift;
5, reusable;
6, the material adopted is copper or aluminium, can meet the reliable connection of conductor and the very little requirement of contact resistance.
