Colloid 12, and conductive copper sheathing 6 is mounted on circuit board assembly 5, in order to avoid light transmission colloid 12 is being molded into shell b13
Light transmission colloid 12 flows into conductive copper sheathing 6 when interior, is set as what conductive copper sheathing 6 was connect by circuit board assembly 5 with circuit board assembly 5
One end sealing, and conductive 6 other end of copper sheathing is connect with ndfeb magnet 11, and sealing, light transmission colloid can be prevented in this way
12 are flowed into conductive copper sheathing 6.
The surface gold-plating of the magnetic conductor 10.In the surface gold-plating of magnetic conductor 10, magnetic conductor 10 can be increased
Electric conductivity allows magnetic conductor 10 to have better contact with magnetic suction head in charging.
The magnetic conductor 10 uses the strong magnetic conductor of neodymium iron boron.Since magnetic conductor 10 is set in ndfeb magnet 11
, and magnet is with magnetizability, therefore magnetic conductor 10 using the metallic conductor that can be magnetized or can directly adopt
Magnet.
Indicator light is provided on the circuit board assembly 5.Indicator light is set on circuit board assembly 5, it can be with real-time display
The charge condition of magnetic charging cable sees whether charging convenient for user.
Magnetic charging cable of the invention when in use, needs to be used cooperatively with magnetic suction head, i.e. magnetic charging cable and magnetic suction head
Connection, specifically, the cathode of magnetic suction head is magnet, magnetic and ndfeb magnet 11 magnetism is on the contrary, magnetic charging cable and magnetic
Head is inhaled together by magnetic, and then by the charging interface of magnetic suction head insertion mobile phone, magnetic suction head is the prior art, this field skill
Art personnel can directly buy on the market, therefore therefore not to repeat here for magnetic suction head.
The present invention is not limited to above-mentioned optional embodiment, anyone can show that other are various under the inspiration of the present invention
The product of form, however, make any variation in its shape or structure, it is all to fall into the claims in the present invention confining spectrum
Technical solution, be within the scope of the present invention.
