The invention discloses a multi-channel bus bar and a forming process thereof, and belongs to the technical field of bus bars for spaceflight, and the multi-channel bus bar is characterized by comprising: a component A made of an insulating material; a rectangular groove penetrating through the front and rear surfaces is formed in the upper surface of the component A, wherein a lug boss A which is arranged in the rectangular groove, and the upper surface of the lug boss A is not higher than the upper surface of the component A; a bus terminal made of a conductive material, wherein the width of the confluence terminal is not greater than that of the rectangular groove, a rectangular or U-shaped welding groove is formed in the upper surface of the convergence terminal, a lug boss B is arranged in the welding groove, a through hole in which the lug boss A is inserted is formed in the lug boss B, and the height of the upper surface of the lug boss B is not greater than that of the upper surface of the convergence terminal; and a component B made of an insulating material, wherein the bus terminal is embedded into the rectangular groove, and the lug boss B is sleeved on the lug boss A, and the component B is fixed on the upper surface of the component A. The welding device has the characteristics of compact structure and convenience in welding.
Description
technical field [0001] The invention belongs to the technical field of bus bars for aerospace, and in particular relates to a multi-channel bus bar and a forming process thereof. Background technique [0002] In an electronic stand-alone machine, cables carrying various voltage and current signals often need to be converged and distributed somewhere to realize various functions, and the current flowing through these wires is usually relatively large. With the development of electronic technology, the confluence device must not only meet the high current switching, but also meet the environmental requirements such as small size and space. This not only requires the connecting conductor to be small in impedance and small in size, but also requires reliable connection. [0003] At present, there are mainly two types of bus bars for aerospace use, one is the way that the bus bar is screwed to the crimping terminal; the other is the way of punching round holes or waist-shaped hol...
