Grade also greatly improves, and header body and the power supply line material class of insulation, up to 100M Ω or more, dieletric strength is reachable
1500V or more.
Preferably, the header body is provided with raised face far from the end face border of inserting column one end.Raised face makes plug more
Add easy gripping, it is more laborsaving when unplugg, it, can also easily pull-up plug even more wet and slippery on hand.
Preferably, one end setting that the power supply line is connect with header body is fluted.
Preferably, the circular connector is fixed on the side of inserting column tail end, and the cable passes through the circular connector
It is electrically connected with inserting column.
Compared with prior art, a kind of three plug of power supply with temperature protection provided by the utility model, is adopted on inserting column
The tensile strength that cable and plug can be increased with 4 points of modes crimped of inserting column with cable, can effectively reduce contact resistance, reduce
Temperature rise designs a prominent end face on the plug of socket, so that plug is chosen more convenient, more laborsaving, even comparing on hand
It is wet and slippery, it can also easily pull-up plug.The utility model is by passing to controller, the work of timely interruptive current for temperature signal
With, prevent unexpected generation, guarantee personal safety, have stronger practical application value.
