The utility model is further arranged to：Magnetic core is equipped in the tube body, the magnetic core uses soft magnetic material.

Through the above technical solutions, magnetic core, using soft magnetic materials such as iron, nickel, steel, after being powered in copper wire, magnetic core produces Magnetisation, to play the role of electromagnet.

The utility model is further arranged to：The snap ring for fixed magnetic core is equipped in the tube body, the snap ring is along tiltedly Extend to 45 ° to tubular body.

Through the above technical solutions, after magnetic core plugs in tube cavity, compressing snap ring deforms upon, and snap ring is i.e. by magnetic core Be stuck in tube cavity securely, can fixed magnetic core, avoid magnetic core from moving, influence inductive effects.

The utility model is further arranged to：It is enclosed with insulating layer on the outside of the copper wire.

Through the above technical solutions, wrapping up copper wire by insulating layer, you can to reinforce insulation performance, copper wire can also be avoided Surface is scratched by foreign matter.

The utility model is further arranged to：The junction of the copper wire and conducting wire is equipped with package blocks.

Through the above technical solutions, package blocks use the drop of resin melted shape behind the junction of copper wire and conducting wire, cooling At can reinforce the stability that copper wire is connect with conducting wire by package blocks, open circuit or the case where poor contact is avoided to occur.

In conclusion the utility model has the advantages that：

1. being coordinated by guide groove one and metallic channel two, it is aided with anti-fault trough, can be good at fixed guide, reinforce conducting wire Stability prevents conducting wire from deforming under external force or being broken；

2. block magnetic core by snap ring, can fixed magnetic core, improve the stability of device.
