Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, and in particular to a waterproof and dustproof controller wire harness that facilitates automated operation. Background Technology

[0002] An automotive NFC reader / writer controller is an in-vehicle electronic module that integrates NFC (Near Field Communication) technology. Its core function is to enable data interaction between the vehicle and smart devices (such as mobile phones and NFC cards) through short-range wireless communication. The working principle of the automotive NFC reader / writer controller is based on the electromagnetic coupling mechanism of NFC near-field communication technology. Combined with the security authentication requirements of the in-vehicle scenario, it realizes short-range data interaction and identity verification between the device and the vehicle. The overall process can be broken down into four key stages: "power supply - data transmission - security verification - command execution".

[0003] When using an automotive NFC reader / writer controller, a wiring harness is required to connect to the vehicle's control system. The current wiring harness mainly consists of wires, connectors, and multiple connection terminals. The wires are composed of multiple core wires twisted together. The connector includes an insulating shell and multiple conductive terminals. The front end of the insulating shell has a receiving cavity, and the multiple conductive terminals are embedded and fixed within the insulating shell. The pin portion at the front end of each conductive terminal is located within the receiving cavity, and the rear end of each conductive terminal is electrically connected to one end of the corresponding core wire. The multiple connection terminals are electrically connected to the other end of the corresponding core wire.

[0004] However, the insulating shell structure of the aforementioned connectors is complex, with multiple conductive terminals fixed inside the shell through an inlay molding process. Furthermore, the pin portion is obscured by the insulating shell, making automated detection of the pin position impossible and causing problems for automated production. Additionally, the aforementioned wire harnesses have poor waterproof and dustproof performance, failing to meet usage requirements. Therefore, it is necessary to improve the current wire harnesses.
