This disclosure is a connection mechanism of transmission lines, which comprises two transmission lines, a circuit board, a chip, a metal shell and an insulation shell. The outer sheath at one end of the two transmission lines is removed, and then conducting wires and conductive layers will be exposed. The conducting wires of the two signal transmission lines are connected to each other through the circuit board and the chip, and the metal shell covers the circuit board and the chip. Further, the metal shell is connected to the exposed conductive layer of the two transmission lines, and the insulation shell covers the metal shell and part of the two transmission lines. The connection mechanism is formed between the two transmission lines to extend the length of the transmission line, which improves the connection strength and compensates the attenuation of the transmission signal.

A signal transmission device of the present disclosure has a bus cable, conductive parts and a connection device. The bus cable formed by sequentially stacking a conductor layer, a metal layer and an insulation layer has signal wires. Each of the signal wires has a predetermined width, and each adjacent twos of the signal wires have a predetermined gap therebetween. Each two of the conductive parts have a specific gap therebetween, and each of the conductive part has a first contact terminal and a second contact terminal thereon, wherein the first contact terminals electrically contact the metal layer. The connection device electrically connected to the bus cable has signal conduction wires and ground wires. The signal conduction wires electrically contact the signal wires one by one. The second contact terminals electrically contact the ground wires one by one.

This disclosure is a transmission line, which comprises an inner conducting core, an insulation layer, a conductive layer and an outer sheath. The insulation layer covers the inner conducting core, the conductive layer covers the insulation layer, and the outer sheath covers the conductive layer. The outer sheath at one end or both ends of the transmission line includes a thinned part, wherein the cross-sectional area of the thinned part is smaller than that of the outer sheath. The conductive layer is folded to the thinned part of the outer sheath, and forms a folded part on the thinned part to reduce the cross-sectional area of one end or both ends of the transmission line. A connector is connected to the transmission line without reducing the wire diameter of the inner conducting core, so as to increase the signal transmission distance of the transmission line.

This invention is a coaxial cable and a signal transmission assembly thereof. The coaxial cable includes a conductive cored wire, an insulating tape and a metal foil Mylar film a conductive layer and an outer jacket. The conductive cored wire includes an outer peripheral surface. The insulating tape is wrapped onto the outer peripheral surface of the conductive cored wire in a spiral winding manner or a longitudinal wrapping manner. The metal foil Mylar film is wrapped onto the insulating tape in a spiral winding manner, a longitudinal wrapping manner, and the conductive layer is wrapped onto the metal foil Mylar film. The jacket is wrapped onto the conductive layer. A distance between the conductive core wire and the metal foil Mylar film can be adjust by control the number of wrapping turns of the insulating tape to improve the yield rate of the coaxial cable manufacturing.
