Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] The following will further describe the present application in detail in conjunction with the attached Figures 1-4 drawings.

[0022] A pin structure for a magnetic suction head of a power cord includes a housing 4 of the magnetic suction head. A fixing hole 3 is formed in the housing 4, and a fixing ring 2 is fixedly arranged in the fixing hole 3. A conductive pin 5 is inserted into the fixing ring 2. The conductive pin 5 is connected with a connecting rod 9. A connecting piece 10 is fixedly arranged in the housing 4. The connecting rod 9 abuts against the connecting piece 10. The connecting piece 10 is fixedly connected with a wire 7. The wire 7 is arranged on the housing 4. When the wire 7 is energized, electricity acts on the conductive pin 5 through the connecting piece 10 and the connecting rod 9.

[0023] The conductive pin 5 includes a fixing cylinder 6 and a pressing rod 1. The fixing cylinder 6 is inserted into the fixing ring 2, and the pressing rod 1 is inserted into the fixing cylinder 6. The connecting rod 9 is fixedly connected to one end of the fixing cylinder 6 away from the pressing rod 1. One end of the pressing rod 1 away from the fixing cylinder 6 extends outside the fixing hole 3.

[0024] A spring 8 is fixedly arranged at one end of the pressing rod 1 close to the fixing cylinder 6. One end of the spring 8 is fixedly connected in the fixing cylinder 6. The spring 8 is between the pressing rod 1 and the fixing cylinder 6. The fixing ring 2 is made of a magnetic insulating material.

[0025] When using the magnetic suction head, the housing 4 is fixed on the item to be charged through the magnetism of the fixing ring 2. The pressing rod 1 abuts against the item, the spring 8 is compressed, the fixing cylinder 6 moves in the fixing ring 2, and the connecting rod 9 abuts against the connecting piece 10. At this time, when the wire 7 is energized, electricity sequentially passes through the wire 7, the connecting piece 10, the connecting rod 9, the fixing cylinder 6, the spring 8 and the pressing rod 1, and finally acts on the item.

[0026] The conductive pin 5 is made of a material with good electrical conductivity, only has electrical conductivity, does not have magnetism, and will not adsorb impurities on the conductive pin 5, so that the impurities are not likely to affect the electrical conductivity of the conductive pin 5. A limiting ring 11 is fixedly arranged at one end of the fixing cylinder 6 away from the connecting rod 9. The fixing cylinder 6 is between the limiting ring 11 and the connecting rod 9. The limiting ring 11 plays a role in limiting the fixing cylinder 6, so that the fixing cylinder 6 is not likely to fall off from the fixing ring 2.

[0027] The implementation principle of this embodiment is as follows: When in use, bring the magnetic head closer to the item to be charged. Through the magnetism of the fixing ring 2, fix the outer shell 4 on the item. At this time, the pressing rod 1 presses against the item, the spring 8 is compressed, the fixing cylinder 6 moves downward in the fixing ring 2, the connecting rod 9 presses against the connecting piece 10, energize the wire 7, and the electricity acts on the item through the wire 7, connecting piece 10, connecting rod 9, fixing cylinder 6, spring 8 and pressing rod 1. Since there is no magnetism on the conductive pin 5, the conductive pin 5 does not adsorb impurities and attach to the conductive pin 5 to affect conductivity, achieving the effect of not affecting the conductivity of the magnetic head.
