Problems solved by technology
The existing flexible connection laminate with a large cross-sectional area has a small number of braid layers, and the braided round copper wire has a thicker diameter and significantly poorer softness, which leads to the movement of the moving contact busbar connected to the flexible connection conductor. The resistance is large, which affects the closing force and closing holding force, and also affects the opening and closing speed; in addition, it is difficult to connect and assemble the two ends of the existing soft connection conductor with the moving contact busbar and the input or output copper bar.

Embodiment Construction
[0011] The following combined with the drawings and the cross-sectional area is 630mm 2 The embodiment of the flexible connection superposed body further illustrates the present invention.
[0012] Such as figure 1 As shown, one end of the copper connection terminal in this embodiment is a horizontal connection terminal 1 and the other end is a vertical connection terminal 2, so as to be respectively connected to the corresponding moving contact bus bar and the input or output copper bar. The flexible connection stack 3 between the horizontal connection end 1 and the vertical connection end 2 consists of a cross-sectional area of 6.2mm each 2 The two ends of the 102 copper stranded braided bands 31 are made of copper pipes. The two ends of the 102 copper stranded braided bands 31 are respectively sleeved into the horizontal connection end 1 and the vertical connection end 2. The flat connection end 1, the vertical connection end 2 and the two ends of the flexible connection sup...

Abstract
The invention discloses a flexible connecting conductor, which comprises copper connecting ends at two ends, and a flexible connecting overlaying bodies consisting of a plurality of copper stranded woven belts in the middle. Both ends of the copper stranded woven belts are connected with the copper connecting ends respectively. The copper stranded woven belts are stranded by layers as follows: a plurality of circular copper lines with diameter theta smaller than or equal to 0.05 mm are stranded into a copper line unit strand, a plurality of copper line unit strands are stranded into a copper strand, and a plurality of copper strands are stranded into a copper stranded woven belt; the copper stranded woven belts in parallel form a copper strand woven belt layer, and the copper strand woven belt layers are overlaid up and down to form the flexible connecting conductor with a rectangular cross section. According to the flexible connecting conductor, the flexibility of the flexible connecting conductor is greatly improved, the moving resistance of a busbar of a moveable contact is further reduced, the switching force and the switching maintaining force are reduced, the switching speed is improved, and the service life of high-low voltage electric equipment is prolonged.
Description
Technical field [0001] The invention relates to a connecting conductor between high and low voltage electrical equipment and an input or output copper bar, in particular to a flexible connecting conductor used for connecting a moving contact bus bar of a DC high-speed circuit breaker and an input or output copper bar, belonging to the supply and distribution Electrical equipment technology field. Background technique [0002] Flexible connecting conductors are widely used to connect the moving contact busbars of high and low voltage electrical appliances, vacuum circuit breakers and high and low voltage switch cabinets with input or output copper bars. The existing flexible connecting conductors use wire diameters of Φ0.10mm, Φ0.15mm Or Φ0.20mm high-quality round copper wire is hinged and braided into a single-layer braided belt with the same width as the connecting ends at both ends, and the single-layer braided belt is stacked layer by layer into a flexible connection laminate ...
