The working principle of the using method of the invention is as follows:
When the wiring is required to be installed, firstly, the wire end of the cable 4 passes through the transverse horizontal section of the limit radiating box 13 and the middle through hole of the air bag piece 14, at the moment, the guide plate 11, the conductive contact 12, the limit radiating box 13, the air bag piece 14, the fixed cavity box 15, the movable plate 16, the movable magnetic block 17, the baffle plate 18, the pressing block 19 and the tangent knife 20 are all in a state of sleeving on the wire body of the cable 4, after the cable 4 is sleeved, the wire end of the cable 4 is inwards inserted into a wiring bayonet matched with the wire end of the cable, after the cable 4 is installed, the fixing clamping groove 7 is aligned with the position of the copper sheet 3, the conductive fixing support 6 is vertically downwards inserted into two sides of the fixing clamping groove clamping post 2 until the bottom end of the insulating plate 5 contacts with the top end of the fixing clamping groove clamping post 2, after the insulating plate 5, the conductive fixing support 6 and the fixing clamping groove 7 are installed, at the moment, the surface of the conductive fixing support 6 and the surface of the guide plate 11 are relatively clung, after the position is confirmed, the conductive fixing support 6 and the guide plate 11 are fixedly connected through the fixing support 6 and the fixing support plate after the fixing support 4, the current can be transferred into the cable 4 after the cable 4 is installed, and the data can be scheduled.
When the cable 4 is subjected to power data scheduling transmission, heat energy is generated at the cable 4 due to continuous power on, the cable 4 is positioned in the clamping groove, the space is narrow and relatively closed, the cable 4 is not easy to dissipate heat, excessive heat is extremely easy to store, the conductive fixing support column 6 has heat conductivity, the heat energy at the conductive fixing support column 6 is conducted through the guide plate 11, the temperature at the cable 4 is reduced, the heat energy at the cable 4 is quickly conducted to the surface of the limiting heat dissipation box 13 through the heat conducting silica gel coated on the surface of the limiting heat dissipation box 13, the temperature of the guide plate 11 is kept low, the heat energy at the cable 4 and the conductive fixing support column 6 can be conducted again, the heat dissipation effect at the cable 4 is ensured, and the heat energy is conducted to the limiting heat dissipation box 13, the air in the air bag part 14 is heated and rapidly expands, the air bag part 14 expands outwards to extrude the transverse horizontal section structure of the limit radiating box 13, the limit radiating box 13 expands outwards together, when the surface of the limit radiating box 13 expands outwards, the contact area between the limit radiating box 13 and the external environment becomes larger, because the air cooling radiating equipment is generally arranged outside the traditional distribution frame, but low-temperature air flow can only flow around the clamping groove and can not flow into the clamping groove in a large area, when the limit radiating box 13 positioned outside the clamping groove expands outwards, the contact surface between the limit radiating box 13 and the external low-temperature air flow also becomes larger, thereby effectively promoting the heat exchange efficiency of the air cooling air flow arranged on the surface of the limit radiating box 13 and the outside, accelerating the heat dissipation and cooling efficiency of the limit radiating box 13, and further effectively ensuring that the wire end of the cable 4 can obtain good cooling, and improves the overall heat dissipation effect of the cable 4.
