Connection line for front lens and rear lens of automobile data recorder

Abstract

The invention relates to a connection line for a front lens and a rear lens of an automobile data recorder. The connection line comprises connectors and a line body, wherein the two connectors are arranged at two ends, the line body is arranged between the two connectors and comprises a first signal line, a second signal line, a third signal line, a fourth signal line, a first power line and a second power line, the first signal line and the second signal line are twisted to form dual twisted lines, the dual twisted lines and a first ground wire are coated in a first conductive layer to form aP+ signal line, the third signal line and the fourth signal line are twisted to form dual twisted lines, the dual twisted lines and a second ground wire are coated in a second conductive layer to form an N+ signal line, and a weaving layer and an insulation layer are sequentially coated outside the P+ signal line, the N+ signal line, the first power line and the second power line. In the connection line, the first conductive layer and the second conductive layer respectively wrap the P+ signal line and the N+ signal line, thus, signal attenuation is consistent, no phase change during the signal transmission process is caused, the interference-resistant capability is high, the pollution to an electromagnetic wave space is reduced, harm to a human body is reduced, and the connection line conforms to the requirement of safety standard.

Description

technical field [0001] The invention relates to the technical field of automotive electronic products, in particular to a front and rear lens connecting line of a driving recorder. Background technique [0002] Drive recorder is the instrument of the relevent informations such as image and sound in registration of vehicle traveling way. Driving recording is installed After instrument, the video image and sound of running car overall process can be recorded, evidence can be provided for traffic accident. A driving recorder that can record both front and rear simultaneously is called a dual-channel driving recorder. It needs to use a front and rear lens connection cable to connect the front and rear lenses of the driving recorder. If they are mixed and used together, the signal line will be easily disturbed, causing the image of the rear lens to be unstable, such as jumping, image difference, and noise. Severe electromagnetic waves can cause harm to the human body. Content...
