That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a PD fast charging head with dynamic power adjustment function, including a PD fast charging head body 1 and a connector 2 plugged with the PD fast charging head, a pressure plate 3 is provided above the PD fast charging head body 1, an L-shaped groove 5 is provided at one end of the pressure plate 3, an L-shaped plate 4 is provided in the L-shaped groove 5, a wiring port 6 is formed between the L-shaped plate 4 and the L-shaped groove 5, the bottom surfaces of the L-shaped plate 4 and the pressure plate 3 are arranged in contact with the top surface of the connector 2, the wires on the connector 2 are arranged through the wiring port 6, a connecting groove 13 is provided on one side of the PD fast charging head body 1, a connecting plate 10 is provided in the connecting groove 13, one end of the connecting plate 10 is installed on the bottom surface of the pressure plate 3, and the other end of the connecting plate 10 is installed with a compression spring for pulling down the pressure plate 3.

[0021] In this embodiment, the L-shaped plate 4 and one end of the L-shaped groove 5 form a retreat space, and the other end of the L-shaped plate 4 protrudes to form a hand-pull portion 7. A positioning groove is provided at one end of the pressure plate 3 facing the hand-pull portion 7, and a positioning column 8 is provided in the positioning groove. A first compression spring is installed at one end of the positioning column 8, and the other end of the first compression spring is installed on the inner wall surface of the positioning groove. The other end of the positioning column 8 extends to the outside and is installed on the hand-pull portion 7. The bottom surface of the hand-pull portion 7 protrudes to form a plurality of inserting portions 12, and a plurality of slots 9 are provided on the top surface of the PD fast charging head body 1, and the slots 9 and the inserting portions 12 are staggered.

[0022] Among them, the dynamic power adjustment function is an important part of PD fast charging technology, which allows the charger and the device to dynamically adjust the voltage and current according to actual needs to achieve more efficient and safer charging;

[0023] This function has been supported and applied in USB-PD 2.0 and later versions, especially in USB-PD 3.0 and USB-PD 3.1 versions. Due to the support of higher power output and more charging protocols, the dynamic power adjustment function has been more widely used. Therefore, this fast charging head is a PD fast charging head body after version 2.0, which has its own dynamic power adjustment function.

[0024] In this embodiment, slide grooves 16 are vertically provided on both sides of the connecting groove 13, and slide bars 11 are protruded on both sides of the connecting plate 10. The slide bars 11 are slidably set in the slide grooves 16. A plurality of grooves 15 are provided on the bottom surface of the connecting plate 10, and second compression springs 14 are installed inside the grooves 15. The other ends of the second compression springs 14 are installed on the bottom surface of the connecting groove 13. The connecting plate can be limited by the slide grooves and the slide bars so that the connecting plate can only move up and down along the slide grooves.

[0025] In this embodiment, the cross-section of the positioning column 8 and the positioning groove is set to a rectangular structure, so that the L-shaped plate can only move laterally along the positioning groove, avoiding the deviation of the L-shaped plate. The positioning column is made of metal material, which increases the firmness and avoids breakage.

[0026] In this embodiment, the outer side surface of the connecting plate 10 is arranged flush with the outer side surface of the PD fast charging head body 1, thereby preventing the outer side of the connecting plate from protruding and affecting the flatness.

[0027] When in use, first pull the L-shaped plate outwards through the hand-pull part to open the L-shaped plate and the L-shaped groove. At this time, the wire can be inserted between the L-shaped plate and the L-shaped groove, and the connector can be inserted into the interface of the PD fast charging head body. After releasing the L-shaped plate, the first compression spring can move toward the pressure plate until the L-shaped plate is against the wire, and a wiring port is formed between the L-shaped plate and the L-shaped groove, which can limit the wire and prevent it from detaching from the pressure plate, so that the pressure plate can press the connector down more stably;

[0028] After releasing the pressure plate, the connection plate, the pressure plate and the L-shaped plate can be pulled downward by the pullback of the second compression spring, and the joint can be tightened by the descending pressure plate and the L-shaped plate, thereby reducing the probability of loosening.

[0029] When not in use, the L-shaped plate can be pulled apart to open the L-shaped plate and the L-shaped groove. After the wire is removed, the connector can be pulled out upwards to complete the disassembly.

[0030] After the wire is taken out, the obstruction of the wire is removed, and the L-shaped plate can be pulled back by the first compression spring to make the L-shaped plate fit the L-shaped groove. At this time, the pressure plate and the L-shaped plate are combined to form a complete plate, and the pressure plate and the L-shaped plate can be pressed against the top surface of the PD fast charging head body by the second compression spring, and the interface is covered to prevent the entry of external dust; wherein, the inserting part on the hand-pull part can be inserted into the slot, thereby positioning the L-shaped plate horizontally, avoiding the situation of opening outward when not in use, and increasing the sealing effect of the interface.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
