As shown in FIG. 2 , a connector set includes a connector 3 and a connection port 4 , wherein the connector 3 has a joint body 31 , two variable pole magnets 32 , 33 and a magnetic pole control element 34 .

The variable pole magnets 32 and 33 are respectively disposed on two sides of the joint body 31 . The magnetic pole control element 34 is electrically connected with the variable magnetic pole magnets 32 , 33 .

The connection port 4 has a slot 41 and two permanent magnets 42, 43. The permanent magnets 42, 43 face the connector 3 and are respectively arranged on two sides of the slot 41 corresponding to the variable pole magnets 32, 33. In order to effectively indicate the insertion direction of the connector 3, the polarities of the permanent magnets 42 and 43 are opposite. S pole. Similarly, the polarities of the variable magnetic pole magnets 32 and 33 are also opposite, so that the variable magnetic pole magnets 32 and 33 are respectively attracted to the permanent magnets 42 and 43 at the same time, or are respectively simultaneously repelled.

The magnetic pole control element 34 of the connector 3 controls the polarity of the variable magnetic pole magnets 32, 33. For example, if the user wants to insert the connector 3 into the connection port 4, he can operate the magnetic pole control element 34 to change the polarity of the variable magnetic pole magnets. The polarity of the pole magnets 32 , 33 makes the variable pole magnets 32 , 33 attract the permanent magnets 42 , 43 of the connection port 4 , so that the connector body 31 can be guided and inserted into the slot 41 of the connection port 4 . In this embodiment, it can be preset that the polarity of the variable magnetic pole magnets 32 , 33 is originally attracted to the permanent magnets 42 , 43 of the connection port 4 .

Conversely, if the user wants to remove the connector 3 from the connection port 4, he can operate the magnetic pole control element 34 to change the polarity of the variable magnetic pole magnets 32, 33, so that the variable magnetic pole magnets 32, 33 come into contact with the connection port. The permanent magnets 42, 43 of 4 repel each other, and the repelling magnetic force can assist the user to remove the connector 3 from the connection port 4.

After the connector body 31 is inserted into the slot 41, the permanent magnets 42, 43 will push the variable pole magnets 32, 33 and the connecting rod 372 on each chute 35, and the spring 371 is compressed, so that the variable magnetic pole magnets 32, 33 slide to the second position P ₂ . When the joint body 31 is removed from the slot 41 , the compressed spring 371 is released to push the connecting rod 372 and the variable pole magnets 32 , 33 , so that the variable magnetic pole magnets 32 , 33 are pushed to the first position P ₁ .

In addition, in order to effectively assist the insertion of the connector body 31 into the slot 41 , the magnetic force of the variable pole magnets 32 , 33 is greater than the elastic restoring force of the compressed spring 371 , so that the spring 371 can prevent the insertion action of the connector body 31 from being hindered.

In use, as shown in Figure 3, if the user wants to insert the connector 3, he can press the magnetic pole control element 34 to change the polarity of the variable magnetic pole magnets 32, 33 so as to be compatible with the permanent magnet 42 of the connecting port 4. , 43 attract each other, and the attraction of the magnets can guide the joint body 31 of the connector 3 to be inserted into the slot 41 of the connection port 4, and can assist the joint body 31 of the connector 3 to be accurately positioned to the slot 41 of the connection port 4.

In addition, if the user reversely connects the connector 3, the variable magnetic pole magnets 32, 33 will just repel the permanent magnets 42, 43 of the connecting port 4, so that the joint body 31 of the connector 3 cannot be connected smoothly. Insert it into the slot 41 of the connection port 4, and the user can know that the connector 3 is reversed.

As shown in Figure 4, if the connector 3 is to be removed from the connection port 4, the user can press the magnetic pole control element 34 so that the polarity of the variable magnetic pole magnets 32, 33 can be connected to the permanent magnet 42 of the connection port 4. , 43 repel each other, the mutual repulsion of the magnets can provide a force to guide and assist the joint body 31 of the connector 3 to separate from the slot 41 of the connecting port 4, and can withdraw quickly.

Therefore, even if the user cannot see the connection port 4 , the connector 3 can be plugged and unplugged smoothly, and the connector 3 can be positioned on the connection port 4 by non-contact natural force (magnetic force). Utilizing the polarities of the variable pole magnets 32, 33 and the permanent magnets 42, 43 can speed up the alignment speed when the connector 3 is inserted.
