Description

Transmission line

technical field

The invention relates to a transmission line, in particular to a more secure transmission line.

Background technique

In addition to the battery, the power supply source of the general electronic product also has an indoor power supply by plugging in a power transmission line.

Referring to Fig. 1, it is the existing notebook computer 1 and the transmission line 2 that it is equipped with. One end of the transmission line 2 has a socket connector 21, and the other end is provided with a plug 22 that can be inserted into the household socket 3. Moreover, a plurality of cables are connected to the socket connector 21 and the plug 22 (the viewing angle is not shown because the cables are covered in the insulating sheath). The socket connector 21 has a plurality of protruding terminals 211 and a magnetic wall 212 surrounding the terminals 211 . The notebook computer 1 is oppositely provided with a connection port 11 , and the connection port 11 has a plurality of contact points 111 corresponding to the terminals 211 on the socket connector 21 . In use, the receptacle connector 21 of the transmission line 2 is used to dock with the connection port 11, and each terminal 211 is contacted with each corresponding contact point 111 to generate electrical conduction, and the magnetic wall on the receptacle connector 21 212 and at the same time absorb the metal parts around the contact points 111 of the connection port 11, so that the receptacle connector 21 can be plugged into the connection port 11 more stably. Then the plug 22 is plugged into the household socket 3, and the household electricity can be converted into the required power for the notebook computer 1 to use.

When the cables of the existing transmission line 2 transmit current, the contact point will generate high resistance value, which will cause power dissipation and block the transmission of current, resulting in the receptacle connector 21 and the cable being disconnected or plugged in. It is easy to burn out, and because the socket connector 21 is directly inserted on the connection port 11 of the notebook computer 1, so when the socket connector 21 burns out, the connection port 11 of the notebook computer 1 will also be damaged at the same time. suffered a great loss.
