As used in this description, the terms "may" and "can" include any one of the possible combinations of the items that are being described.
[0024] Referring to Figure 1 An electromagnetic shielding automobile lithium battery protection wire harness includes a first wire harness 100, a second wire harness 200, a third wire harness 300, and a fourth wire harness 400. One end of the first wire harness 100, the second wire harness 200, and the third wire harness 300 is connected to a wiring terminal of a first connector 500. The other end of the first wire harness 100 and the second wire harness 200 is connected to a second connector 600. The other end of the third wire harness 300 is connected to a third connector 700. One end of the fourth wire harness 400 is connected to the third connector 700, and the other end of the fourth wire harness 400 is connected to a fourth connector 800.
[0025] Specifically, in the embodiment, the protection wire harness includes a first wire harness 100, a second wire harness 200, a third wire harness 300 and a fourth wire harness 400, wherein the first wire harness 100 and the second wire harness 200 are positive and negative polarity wires (+V, -V) for connecting the positive and negative poles of the automobile lithium battery or the positive and negative power supplies of the vehicle-mounted circuit, the third wire harness 300 is used for connecting the VDM board for collecting the voltage information of the battery, and the fourth wire harness 400 is used for collecting the temperature information of the battery and transmitting it to the electronic control unit. Finally, the voltage, current and temperature information of the battery are collected through the first wire harness 100, the second wire harness 200, the third wire harness 300 and the fourth wire harness 400 to ensure that the battery operates in a safe state and is managed in a state. In addition, in the embodiment, one end of the first wire harness 100, the second wire harness 200 and the third wire harness 300 is connected to the wiring end of the first connector 500, and the other end of the third wire harness 300 and one end of the fourth wire harness 400 are connected to the third connector 700. The first connector 500 integrates the first wire harness 100, the second wire harness 200 and the third wire harness 300, and the third connector 700 integrates the third wire harness 300 and the fourth wire harness 400, thereby reducing the number of connectors, reducing the cost of the wire harness, and facilitating the arrangement of the first wire harness 100, the second wire harness 200, the third wire harness 300 and the fourth wire harness 400, thereby simplifying the overall structure of the protection wire harness.
[0026] In addition, in order to facilitate the arrangement of the protection wire harness, the fourth wire harness 400 and the third wire harness 300 are wrapped with acetic acid tape 900. Since one end of the fourth wire harness 400 and one end of the third wire harness 300 are connected to the third connector 700, the third wire harness 300 and the fourth wire harness 400 are wrapped with acetic acid tape 900, thereby facilitating the arrangement of the third wire harness 300 and the fourth wire harness 400, and effectively preventing the fourth wire harness 400 from being disconnected from the third connector 700.
[0027] In order to facilitate the viewing of the information of the protection wire harness, an information tag 1000 is arranged on the third wire harness 300. The information tag 1000 has material code, material description, supplier name, two-dimensional code and other contents. The production of the protection wire harness can be understood through the information tag 1000, thereby facilitating the use of the protection wire harness.
[0028] Please refer to Figure 2In order to ensure safety, the first wire harness 100, the second wire harness 200, the third wire harness 300 and the fourth wire harness 400 in the embodiment are the same in structure, and each comprises a wire core 110, a conductive layer 120 and a protective layer 130 arranged in sequence from inside to outside, the conductive layer 120 is wrapped on the wire core 110, and the protective layer 130 is wrapped on the conductive layer 120, wherein the wire core 110 is made of tinned copper material, the conductive layer 120 is made of conductive cloth material, and the protective layer 130 is made of glass fiber tube. Since tinned copper has good electromagnetic admittance characteristics, it can effectively reduce high-frequency electromagnetic interference, and the conductive cloth and the glass fiber tube can provide mechanical protection and further enhance the shielding performance, so that the first wire harness 100, the second wire harness 200, the third wire harness 300 and the fourth wire harness 400 can effectively reduce external interference to ensure safety. In addition, the wiring end of the first connector 500 is also wrapped with conductive cloth 510, which can also prevent external electromagnetic interference from affecting the internal circuit to improve the electromagnetic shielding effect.
[0029] Finally, please refer to Figure 1 and Figure 3 In order to facilitate the plugging function of the first connector 500 and protect the first connector 500, a dust cover 520 is arranged on the first connector 500, and a clamping block 530 is arranged on each side of one end of the first connector 500, and the rear end of the clamping block 530 is inclined. The dust cover 520 can protect the first connector 500, and the clamping block 530 and the inclined rear end of the clamping block 530 can facilitate the plugging of the first connector 500, so that the use of the protective wire harness is more convenient.
