Technical Field

[0001] This utility model relates to a cable, specifically an automotive signal adapter cable. Background Technology

[0002] Automotive signal adapter cables are cables used to connect different devices or interfaces. They are mainly used to transmit signals or convert power types to ensure device compatibility.

[0003] Existing automotive signal adapter cables have a complex structure and unreasonable design. The connection between the wire and the front-end terminal lacks protective measures. During operation, the wire experiences significant pressure, exhibiting poor high-temperature resistance and aging resistance, posing a risk of short circuit and burnout. Furthermore, during operation, external dust and moisture can slowly seep into the rear-end terminal, leading to internal corrosion and shortening its lifespan. Therefore, the inventors have improved the structure of the automotive signal adapter cable. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive signal adapter cable, which has a simple structure and reasonable design. Thanks to the protective tape, the end of the main harness has the characteristic of being able to withstand voltage volts, which can effectively prevent short circuits caused by cable contact. It also improves the high temperature resistance and anti-aging ability of the protective tape. The waterproof plug makes the first terminal have anti-corrosion function, ensuring safety and solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive signal adapter cable, comprising a main wiring harness, with a front-end terminal and a rear-end terminal connected to both ends of the main wiring harness. The main wiring harness includes a second wire and a first wire and a third wire respectively disposed at both ends of the second wire. A protective tape is disposed on the first wire, the second wire, and the third wire, and the first wire, the second wire, and the third wire are connected as one unit by the protective tape. The protective tape is disposed at the end of the main wiring harness near the front-end terminal. The rear-end terminal includes a first rear terminal, a second rear terminal, and a third rear terminal arranged in sequence. The first rear terminal is connected to the first wire, the second rear terminal is connected to the second wire, and the third rear terminal is connected to the third wire.
