Wherein, between described conductor and inner clip, be provided with copper packing.
Wherein, described securing member is bolt.
Wherein, the material that described wire clamp adopts is copper or is aluminium.
The installation method that the present invention is based on the conductor connecting clamp that another object provides, its improvements are: described method comprises the steps:
The diameter of section of the conductor 1, connecting is as required selected the inner clip of two corresponding specification;
2, conductor is coordinated to installation with corresponding inner clip, according to the tightness coordinating, adjust, if the cross section of conductor is bigger than normal, can keep two semicircular ring of inner clip evenly to separate; If cross-sectional area of conductor is less than normal, can, at the surface of conductor parcel one deck copper packing, guarantee after installation the close contact of conductor and inner clip;
3, after two inner clips are coordinated to installation with corresponding conductor, coordinate installation with outer clip; In installation process, make two parts up and down of inner clip stressed evenly;
4, mounting fastener in the through hole at outer clip two ends, and guarantee that conductor fully contacts and fixes with wire clamp.
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, it is fastening that wire clamp adopts screw bolt and nut, is connected firmly, and can guarantee that conductor and fixture can not come off in use procedure;
3, applicable to being connected with the conductor of different cross section;
4, simple in structure, mount and dismount convenient and swift;
5, reusable;
6, the material adopting is copper or aluminium, can meet reliable connection and the very little requirement of contact resistance of conductor.
