The invention relates to a novel automobile wire harness product, an electromagnetic pulse welding method and an application thereof. The automobile wire harness comprises a lead wire and a connectionterminal; and the lead wire is fixedly connected with the connection terminal via an electromagnetic pulse welding process; the electromagnetic pulse welding method specifically comprises the following steps: peeling an end portion of one end of the lead wire; clamping the lead wire and the connection terminal; moving the lead wire and / or the connection terminal, and inserting the peeled end of the lead wire into the connection terminal; stamping, by using the electromagnetic pulse welding process, the connection terminal section into which the lead wire is inserted, so that the connection terminal is tightly combined with the lead wire; loosening the lead wire and the connection terminal, and taking out the automobile wire harness; and the invention further provides an application of theelectromagnetic pulse welding method for fixed connection between the lead wire and the connection terminal of the automobile wire harness. According to the novel automobile wire harness product, theelectromagnetic pulse welding method and the application, not only are the mechanical property and the electrical property met, but also the sealing property is strong; and more preferably, the costis low, the process is simple, and the quality of the machined automobile wire harness is reliable.
Description
technical field [0001] The invention belongs to the technical field of wire harness processing, and in particular relates to a novel automobile wire harness product, an electromagnetic pulse welding method and its application. Background technique [0002] The automobile wiring harness is the main body of the automobile circuit network, and there is no automobile circuit without the wiring harness. The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. [0003] Existing automotive wiring harness production mostly uses technologies such as crimping and ultrasonic welding to combine terminals and wires. In order to ensure the sealing requirements, parts such as heat-shrinkable tubes or sealing rings are also required, which will result in high costs and complicated processes. And wh...
