Problems solved by technology

The connection between the two ends of the traditional automotive air-conditioning wire harness and the terminals connected to it is relatively loose, and the compact effect cannot be achieved, which not only makes the impedance of the wire harness itself high, but also increases the impedance after connecting the terminals
However, due to the narrow installation space of the automotive air conditioner wiring harness, the wire diameter of the wiring harness is generally small. If the impedance at the terminal is increased on this basis, the overall loss of the air conditioner will undoubtedly increase when the air conditioner is working, resulting in an increase in the power consumption of the car. , which increases the burden on the wiring harness
The narrow installation space is not conducive to heat dissipation, and the working conditions of the wiring harness are poor. If the resistance of the wire increases, more heat will be generated, which will not only bring negative effects on the service life of the air conditioning equipment and wiring harness, but also create safety hazards for the overall operation of the car.

Abstract

The invention relates to the technical field of automobile wire harness manufacture, in particular to an automobile wire harness crimping technology. A low-impedance automobile wire harness connecting terminal crimping technology is implemented by crimping a connecting terminal and an automobile wire harness body together by stamping equipment, and includes the technological steps of wire harness splitting, die debugging, crimping, tension test and performance detection. By the aid of the technical scheme, the low-impedance automobile wire harness connecting terminal crimping technology has the advantages of easiness in control of equipment input and improvement cost, good generated effects and capability of enabling wire harnesses to have low impedance characteristic and meet more demands of the market.

Description

technical field [0001] The invention relates to the technical field of automobile wire harness manufacturing, in particular to a crimping process for automobile wire harnesses. Background technique [0002] The automotive air conditioner wiring harness is a special wiring harness used to supply power to the air conditioner installed in the car and transmit control signals. The connection between the two ends of the traditional automotive air-conditioning wire harness and the terminals connected to it is relatively loose, which cannot achieve a compact effect, which not only makes the impedance of the wire harness itself high, but also increases the impedance after connecting the terminals. However, due to the narrow installation space of the automotive air conditioner wiring harness, the wire diameter of the wiring harness is generally small. If the impedance at the terminal is increased on this basis, the overall loss of the air conditioner will undoubtedly increase when th...
