Referring to fig. 1 to 5, an adapter 100 according to an embodiment of the present invention includes a housing 20, a circuit board 30 disposed in the housing 20, and a pin mechanism 50, wherein the pin mechanism 50 is disposed in the housing 20. The prong mechanism 50 includes a prong assembly 51 slidably connected within the housing 20 and an operating assembly 53 slidably connected to the housing, preferably, the operating assembly 53 is slidably inserted into the prong assembly 51. The pin assembly 51 comprises at least one first magnetic member 510 and a pin piece 511; the operating assembly 53 includes a second magnetic member 530 and a third magnetic member 531 spaced apart from each other, and the second magnetic member 530 and the third magnetic member 531 are spaced apart from each other along a sliding direction of the operating assembly 53. The sliding of the operating unit 53 drives the second magnetic member 530 to move closer to the first magnetic member 510, so that the pin assembly 51 slides along a first direction until the pin piece 511 extends out of the housing 20 (as shown in fig. 12); the sliding of the operating element 53 drives the third magnetic member 531 to move closer to the first magnetic member 510, so that the pin assembly 51 slides in the second direction until the pin piece 511 retracts into the housing 20 (as shown in fig. 1). The first direction is a direction in which the pin piece 511 slides to the outside of the housing 20 to extend out of the housing 20, and the second direction is a direction in which the pin piece 511 slides to the inner cavity of the housing 20 to retract into the inner cavity of the housing 20.

When the adapter 100 needs to be used, the user manually operates the operating component 53 to slide along the first direction, so as to drive the second magnetic member 530 to move towards the first magnetic member 510, and the magnetic force between the first magnetic member 510 and the second magnetic member 530 drives the pin assembly 51 to slide along the first direction until the pin piece 511 extends out of the housing 20. At this time, the user can conveniently plug the pin pieces 511 of the adapter 100 into the socket, so that the circuit board 30 is electrically connected to the external power supply. When the adapter 100 needs to be stored, the user manually operates the operating element 53 to slide along the second direction, so as to drive the third magnetic member 531 to move towards the first magnetic member 510, and the magnetic force between the first magnetic member 510 and the third magnetic member 530 drives the pin assembly 51 to slide along the second direction until the pin piece 511 extends out of the housing 20. At this time, the pin piece 511 is conveniently stored, and the pin piece 511 is prevented from being damaged.

The adapter 100 of the present invention may be, but is not limited to, a power adapter, a portable charger, a router, a sound box, a router, a light bar, etc., and in this embodiment, the power adapter is taken as an example for detailed description. The circuit board 30 is electrically connected with electronic devices such as a transformer, an inductor, a capacitor, a control IC, etc., the power adapter is used for converting an alternating current input into a direct current output, and the power adapter is a power supply voltage conversion device of small portable electronic equipment, and is often used in a matched manner on small electronic products such as a mobile phone, a liquid crystal display, a router, a security camera, a set-top box, a sound box or a notebook computer, etc.

The pin assembly 51 of the adapter 100 of the present invention is slidably connected to the housing 20, the operating assembly 53 is slidably connected to the housing 20, the pin assembly 51 is provided with a first magnetic member 510, and the operating assembly 53 includes a second magnetic member 530 and a third magnetic member 531 which are spaced from each other. When the operating unit 53 is operated to slide in the first direction, the magnetic force between the first magnetic member 510 and the second magnetic member 530 drives the pin assembly 51 to also slide in the first direction until the pin piece 511 extends out of the housing 20. At this time, the user can conveniently plug the pin fins 511 of the adapter 100 into the socket, and the operation is simple and the use is convenient. When the operating assembly 53 is operated to slide in the second direction, the magnetic force between the first magnetic member 510 and the third magnetic member 530 drives the pin assembly 51 to also slide in the second direction until the pin piece 511 extends out of the housing 20. At this time, the pin piece 511 is conveniently stored, and the pin piece 511 is prevented from being damaged or contaminated.

The circuit board 30 and the pin piece 511 are electrically connected through a lead 31, and the lead 31 between the pin piece 511 and the circuit board 30 has a reserved section 312. The reserved section 312 is a curved wire 31 between the pin piece 511 and the circuit board 30 when the pin piece 511 is retracted into the inner cavity of the housing 20. The reserved section 312 can prevent the lead wire 31 from being pulled apart during the process of extending the pin piece 511 out of the shell 20; i.e., the wire 31 has a sufficient length to facilitate the sliding of the pin assembly 51.

In this embodiment, the first magnetic member 510, the second magnetic member 530 and the third magnetic member 531 are all magnets. The first magnetic member 510 and the second magnetic member 530 have a magnetic force therebetween for driving the pin assembly 51 to slide along a first direction, and the first magnetic member 510 and the third magnetic member 531 have a magnetic force therebetween for driving the pin assembly 51 to slide along a second direction, wherein the first direction is opposite to the second direction. Specifically, the polar directions between the first magnetic member 510 and the second magnetic member 530 are the same, that is, if the side of the first magnetic member 510 facing the second magnetic member 530 is N-pole, the side of the second magnetic member 530 facing the first magnetic member 510 is also N-pole; if the side of the first magnetic member 510 facing the second magnetic member 530 is an S-pole, the side of the second magnetic member 530 facing the first magnetic member 510 is also an S-pole. The polar directions between the first magnetic member 510 and the third magnetic member 531 are also the same, that is, if the side of the first magnetic member 510 facing the third magnetic member 531 is an N pole, the side of the third magnetic member 531 facing the first magnetic member 510 is also an N pole; if the side of the first magnetic member 510 facing the third magnetic member 531 is S-pole, the side of the third magnetic member 531 facing the first magnetic member 510 is also S-pole.

When the distance between the first magnetic member 510 and the second magnetic member 530 is shorter, the magnetic force for driving the pin assembly 51 to slide along the first direction is stronger; the closer the distance between the first magnetic member 510 and the third magnetic member 531 is, the stronger the magnetic force for driving the pin assembly 51 to slide in the second direction is. Specifically, since the first magnetic member 510 and the second magnetic member 530 have the same polar direction, when the operating assembly 53 slides relative to the pin assembly 51 to gradually decrease the distance between the second magnetic member 530 and the first magnetic member 510, the magnetic force between the second magnetic member 530 and the first magnetic member 510 gradually increases. Similarly, since the polar directions between the first magnetic member 510 and the third magnetic member 531 are the same, when the operating assembly 53 slides relative to the pin assembly 51 to make the distance between the third magnetic member 531 and the first magnetic member 510 gradually smaller, the magnetic force between the third magnetic member 531 and the first magnetic member 510 gradually increases.

The sliding direction of the pin assembly 51 and the operating assembly 53 is the same during the process of extending the pin piece 511 out of the housing 20 or retracting the housing 20. Specifically, the operating assembly 53 moves in a first direction to bring the second magnetic member 530 to move in the first direction, and the magnetic force between the second magnetic member 530 and the first magnetic member 510 causes the pin assembly 51 to slide in the first direction as well; the operating unit 53 moves along the second direction to drive the third magnetic member 531 to move along the second direction, and the magnetic force between the third magnetic member 531 and the first magnetic member 510 makes the pin assembly 51 slide along the second direction.
