[0042] The working principle of the present invention is: the control component 2 starts to run, and the heat dissipation control module 211 and the pressing control module 212 therein start to cooperate with the equipment to shield the outside of the low-voltage wiring harness of the fuel cell. When the work starts, the staff puts the low-voltage wiring harness 10 into the equipment from the side. At this time, the pressing control module 212 in the equipment receives the information, which conveys the information to the controller 21. The controller 21 starts to change the information and sends it to the processor 22, and then the processor 22 starts to control the compression component 3 to operate. When the low-voltage wiring harness 10 passes through the equipment, the cylinder 32 starts to stretch. When the lower pressing plate 33 completely contacts the low-voltage wiring harness 10 and the low-voltage wiring harness 1 0 is fixed, the cylinder 32 stops stretching, and the low-voltage wiring harness 10 is completely fixed at this time; at this time, the elastic heat dissipation gasket 5 begins to wrap the low-voltage wiring harness 10 from the upper and lower surfaces, and the heat dissipation component 4 is arranged on the outside of the elastic heat dissipation gasket 5; at the same time, the outside of the radiator 41 is wrapped with an aluminum foil shielding layer 6, and the low-voltage wiring harness 10 can be shielded from the outside by the complete wrapping of the aluminum foil shielding layer 6, and then a layer of adhesive film 7 is covered on the outside of the aluminum foil shielding layer 6, which has a certain protection and adhesion effect on it, and at the same time, a shell 8 is covered on the outside of the adhesive film 7 to ensure the stability of the entire device; at the same time, there are a number of primary connection blocks 11 and a plurality of primary connection blocks 12 between the radiator 41 and the aluminum foil shielding layer 6. There are several secondary connection blocks 13 and secondary through holes 14 between the aluminum foil shielding layer 6 and the adhesive film 7; these through holes are used for ventilation between materials to facilitate airflow inside the device, and the connection blocks are used to fix the through holes to ensure the fixation between the through holes and the materials of each layer; when the temperature inside the device is too high, the elastic heat dissipation gasket 5 will first have a certain effect on the device and the low-voltage wiring harness 10. When the elastic heat dissipation gasket 5 cannot play a good role, the heat dissipation control module 211 receives the information and transmits the information to the controller 21. At this time, the controller 21 starts to change the information and transmits the information to the processor 22, and then the processor 22 starts to control the heat dissipation component 4 starts to run, at this time, the four groups of radiators 41 are opened to dissipate heat for the low-voltage wire harness 10 and the equipment, and the ventilation block 42 and the ventilation slot 43 are opened, so that the hot air inside the equipment can reach the outside of the equipment through the ventilation slot 43 and the ventilation block 42, and the primary through hole 12, the secondary through hole 14 and the tertiary through hole 16 can not only play a shielding effect, but also circulate the air, so that the internal hot air is released to the outside through the through hole; in this way, the equipment can dissipate heat by itself without manual participation, which greatly reduces the cost; at this point, the entire low-voltage wire harness external shielding structure is completed, which not only ensures the shielding performance of the low-voltage wire harness 10 but also ensures the compactness, stability and good heat dissipation of the low-voltage wire harness 10.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
