DETAILED DESCRIPTION

[0019] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] like Figure 1 As shown, a car seat wiring harness includes a first wiring harness 3 between a backrest 1 and a seat cushion 2, a second wiring harness 6 between a guide rail 4 and a vehicle body 5, and a third wiring harness 7 between the seat cushion 2 and the guide rail 4. Figure 2As shown, the second wiring harness 6 includes a connector 61, a wiring 62 and a fixer 63. The connector 61 has a housing 611. The two outer side walls of the housing 611 are protruded with hooks 612, which are convenient for matching and connecting with the connector on the first wiring harness 3. One end of the housing 611 is provided with two rows of slots, and one row of slots is provided with four wire slots 613. Each wire slot 613 is provided with a connecting terminal 614. There are 8 wirings 62, and each wiring 62 extends into the wire slot 613 and is connected to the connecting terminal 614. The wiring 62 is covered with a rubber sleeve 64. The end of the rubber sleeve 64 away from the connector 61 is provided with a fixer 63 for fixing the wiring 62. The other end of the wiring 62 is connected to the first wiring harness 3. The wiring 62 outside the fixer 63 is connected to other wiring harnesses of the car and fixed on the vehicle body 5. The connection needs to be sealed and plugged to prevent moisture.
