The adapter 1 in the first state means that the pins 20 are closed with respect to the ends 11. The adapter 1 in the second state means that the adapter 20 is open relative to the end. The adapter 1 in the third state is a transition state of the adapter 20 between the first state and the second state.

In the present embodiment, the adapter 1 includes a main body 10, pins 20, a shield 30, and a transmission mechanism 40. The body 10 is provided with an end 11. The pin 20 is slidably connected to the end portion 11 and can extend and retract relative to the end portion 11. The shield 30 is rotatably or slidably attached to the end portion 11 and can be opened or closed with respect to the end portion 11. The transmission mechanism 40 is connected to the shield 30 and the pin 20 for transmitting a rotational or sliding moment of the shield 30 to the pin 20 and causing the pin 20 to telescope relative to the end 11. The transmission mechanism 40 of the adapter 1 transmits the torque of the protective cover 30 to the pins 20, and enables the pins 20 to be telescopic relative to the end portion 11, so that the problems that the pins 20 are fixed in position, easy to wear and easy to pierce other objects in the traditional method are solved.

In this embodiment, the main body 10 is a structure for providing a support protection, and may support the pins 20, the protection cover 30, and the transmission mechanism 40. It is understood that the main body 10 is internally mounted with components such as a power transformer, a rectifying circuit, etc. The body 10 is provided with an end portion 11, the pin 20 is slidably connected to the end portion 11, and the pin 20 is retractable relative to the end portion 11, that is, the pin 20 is extendable relative to the end portion 11, or the pin 20 is retractable relative to the end portion 11. In this embodiment, when the pin 20 extends to the maximum extension stroke relative to the end portion 11, the pin 20 is clamped with the end portion 11, and the pin 20 can be inserted into a female socket of an external circuit to receive an electrical signal of the external circuit. When the pin 20 retracts to the maximum retraction stroke relative to the end portion 11, the pin 20 can be retracted inside the main body 10, so that the pin 20 is prevented from piercing other external objects, and meanwhile, the pin 20 is prevented from being worn. Further, when the protective cover 30 is closed relative to the end portion 11, the protective cover 30 can prevent dust from being accumulated on the end portion 11 and the pin 20.

In other embodiments, the pin 20 being telescopic relative to the end portion 11 means that the pin 20 is extended or retracted relative to the end portion 11 at one side of the body 10.

The specific movement of the pin 20 relative to the end 11 is not limited to sliding, rotating, etc. Specifically, in this embodiment, the pin 20 slides in or out with respect to the end 11. In another embodiment, the pin 20 is rotated in and out relative to the end 11.

Referring to fig. 3 to 5, the transmission mechanism 40 is connected to the shield 30 and the pin 20, and is used for transmitting the rotation or sliding torque of the shield 30 to the pin 20 and extending and retracting the pin 20 relative to the end 11.

Specifically, when the protective cover 30 rotates or slides, the torque generated by the rotation or sliding of the protective cover 30 is transmitted to the transmission mechanism 40, the transmission mechanism 40 receives the torque and transmits the torque to the pin 20, and the pin 20 extends and retracts relative to the end portion 11 under the action of the torque.

Referring again to fig. 1 and 3, the fact that the protective cover 30 is closed with respect to the end portion 11 means that the protective cover 30 covers the end portion 11, protects the end portion 11 and the pins 20, and prevents the end portion 11 and the pins 20 from being worn. Referring to fig. 2 and 4, the protection cover 30 is opened relative to the end portion 11, that is, the protection cover 30 does not cover the end portion 11 and abuts against one side of the end portion 11.

In one embodiment, when the shield 30 is closed, the pins 20 are fully retracted into the receiving portions 12. During the process of switching the hood 30 from closed to open, the pins 20 extend at least partially out of the receptacles 12, and when the hood 30 is open, the pins 20 are fully retracted into the receptacles 12.

In this embodiment, the main body 10 is further provided with a socket end 13 opposite to the end 11, and the socket end 13 is used for plugging an external data line. The protective cover 30 is opened relative to the end portion 11, the pin 20 extends relative to the end portion 11, the pin 20 is inserted into an external power socket, an external data line has a first end and a second end opposite to the first end, the first end of the external data line is inserted into the socket end portion 13, the second end opposite to the data line is inserted into an electronic device, and an external power source is input into the electronic device after being transformed by the adapter 1 to provide power for the electronic device.

The protective cover 30 seals the end 11 so that the pins 20 are not exposed to the protective cover 30, avoiding the pins 20 from piercing objects outside the adapter 1, while avoiding the pins 20 from being worn. Further, the protection cover 30 seals the end portion 11, preventing external dust and liquid from entering the end portion 11, and improving the waterproof and dustproof performance of the adapter 1.

Further, referring again to fig. 4 and 5, the shield 30 has a first end surface 30a, and the first end surface 30a is flush with the end portion when the shield 30 is open relative to the end portion 11. The first end face 30a is flush with the end portion 11, and the first end face 30a and the end portion 11 form a flat plane, so that the adapter 1 can be smoothly plugged into an external socket. It will be appreciated that when the shield 30 is open relative to the end 11, the first end face 20a faces in the positive direction of the Y-axis.
