4 pin 5-0160430-7 Automotive Connector Terminal Rubber Shell Plug-in Housing Plug

6. Conclusion

This article introduces the test method and judgment standard for the end voltage drop of the terminal of the end voltage of the terminal, and compares the comparison. Through comparison, QC/T29106 testing methods and judgment standards and differential standards from the terminal of the terminal side are different from foreign OEMs. It can make more detailed requirements on the terminal pressure and improve the judgment standard.

As a car -transmitting signal and the carrier of the electrical energy, the car beam has a vital role in coordinating and cooperating between car electrical equipment and systems. This article briefly describes the importance of the establishment and application of the car beam database. It aims to reduce the failure rate of the vehicle's electrical appliances and increase the level of wire beam design and manufacturing.

1 Introduction

The car wire beam consists of terminals, protectives, wires, connectors, tapes, ripples, PVC pipes, thermal retractables, fuses, insurance boxes and other attachments. Because the wire beam is different in the vehicle, it is divided into engine wiring, front wire beam, instrument wiring, chassis wire beam, door wire bundle, top wire beam, etc. (Figure 1).

The design process of the cable beam is as follows (Figure 2):

First of all, list the function parts connected to the wiring beam, and then confirm the function of the component with the corresponding electrical engineer, obtain ICD information, and then determine the electrical principle layout diagram. Next, check the principles of each system and organize a complete line beam schematic diagram.

Secondly, after the schematic diagram is determined, the 3D wire beam is distributed. This process is basically defined to install the attachment installation location of the attachment of the insurance box, the connector, the plug, and the positioning buckle. After the 3D direction diagram is determined, the 2D drawing is transformed. The 2D drawings refer to the industry standards. If there are other special requirements for the OEM, it can be determined in the process.

Furthermore, according to the initial 2D drawings, make handmade lines and test verification on the entire vehicle (including static verification and dynamic verification). Based on the results of the trial installation verification, the wiring engineer optimized and adjusted the line beam direction and size. The wire beam plays the role of connecting the entire vehicle electrical parts. Due to the requirements of each electrical system or the installation of the vehicle, the wiring beam needs to be adjusted and optimized in conjunction with each system, that is, the entire development process is also the process of continuously optimizing and updating the design [1].

3 line bundle manufacturing process

The production process of automobile wire beam mainly includes (Figure 3): ① offline; ② pressure connection; ③ pre -installation; ④ assembly; ⑤ relay installation; ⑥ power power detection; ⑦ fuse installation; ⑧ spectrum scan; ⑨ appearance detection, etc. Automotive wiring manufacturing is a labor -intensive industry. The process is mainly manually operated. Due to the technical differences of workers and the instability of the operating method, production control is done during the production process of automobile wire beams. It is very important to formulate standards for each process. Among them, it is very important to formulate standards for various processes. Among them The establishment of databases is particularly important.
