Abstract

The invention discloses a wire harness crimping device and method. A control device obtains target crimping parameters of a wire harness to be crimped and outputs a current control signal according tothe target crimping parameters; a discharge device generates a corresponding pulse current according to the current control signal; a crimping coil generates a magnetic field according to the pulse current, a crimping terminal generates an eddy current under the action of the magnetic field, the eddy current generates pulse electromagnetic force under the action of the magnetic field to drive a crimping terminal to generate plastic radial-shrinkage deformation. According to the technical scheme, the pulse electromagnetic force is correspondingly regulated according to the target crimping parameters such as the cross sectional area of the wire harness to be crimped, the crimping of the wire harnesses with different specifications is achieved with no need for regulation of the sizes and thespecifications of a mold so as to improve the survival efficiency. The pulse electromagnetic force is convenient to control, the precision is high, and therefore, the pass rate of the wire harness crimping is improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pulse formation, in particular to a wire harness crimping device and method. Background technique [0002] The wire harness is an important component to realize the connection between circuits, and its crimping performance directly affects the reliability and stability of the circuit connection. The traditional wiring harness crimping method adopts a mechanical crimping process, uses a suitable mold to fix the wiring harness and the crimping terminal, and applies a certain mechanical stress to cause the crimping terminal to shrink and deform to achieve a firm connection between the two. [0003] With the development of society, the use of electronic equipment is becoming wider and wider, and the specification parameters of wiring harnesses are increasing. The wire harness crimping mold needs to be replaced according to the specifications of the wire harness, which makes the wire harness c...
