Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a copper aluminium binding post, including binding post body 1 and mounting hole 2, binding post body 1 has flat end 101 and cylinder end 102 to constitute, the spout 8 that is side I shape structure is all seted up to the both sides of cylinder end 102, the horizontal end inboard slip of spout 8 has slide bar 9, slider 4 is all installed at the both ends of slide bar 9, the outer terminal surface sliding connection of cylinder end 102 has sliding sleeve 5, and the inner wall of sliding sleeve 5 and the laminating of the outer wall of cylinder end 102, to be connected the electric wire slip and inlay to the inboard of cylinder end 102, through sliding sleeve 5 that slides down, extrude slide bar 9 and slider 4 to the inboard through sliding sleeve 5, through the extrusion force of slider 4 to being connected the electric wire, the installation stability of being connected the electric wire in cylinder end 102 inboard has been promoted.

Specifically, as shown in fig. 1-3, mounting hole 2 that is circular structure is seted up to flat end 101's inside, the preceding terminal surface of flat end 101 is located the outside of mounting hole 2 and is annular equidistance and install multiunit telescopic link 7, the preceding terminal surface fixedly connected with extrusion ring 3 of telescopic link 7, the cover is equipped with extrusion spring 6 between extrusion ring 3 and the flat end 101 to the outer terminal surface of telescopic link 7, in the use, after the mounting screw takes place to become flexible, through the setting of extrusion spring 6 and telescopic link 7, promote flat end 101 and other electrically conductive positions closely to laminate under the extrusion force effect through extrusion spring 6, thereby compensate the damage to the clearance department after the screw is not flexible.

Specifically, as shown in fig. 3, the slider 4 slides at the inner side of the vertical end of the sliding groove 8, the lateral end of the slider 4 is in a semicircular structure, the radius of the slider 4 is equal to the horizontal length of the vertical end of the sliding groove 8, the slider 4 and the sliding rod 9 are prevented from sliding out of the inner side of the sliding groove 8, and meanwhile, the sliding sleeve 5 is convenient for pushing the slider 4 to the inner side due to the arrangement of the hemispherical structure.
