Along with the development of the times, electronic equipment is increasingly abundant, and meanwhile, the types of quick-charging equipment of the electronic equipment are gradually increased. The PD is one of the mainstream quick charging protocols at present, the PD quick charging protocol is output by a Type-C interface, the PD quick charging protocol can increase the power transmission through a USB cable and a connector, and the power supply capacity of a cable bus in USB application is expanded, so that the purpose of improving charging voltage or current is achieved, and the power transmission direction can be freely changed. In the related art, the PD quick charger has the problems of large size and inconvenient carrying.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a charging plug according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of an explosion of the charging plug in fig. 1. The charging plug 100 comprises a pin assembly 1, an upper cover 2 and a lower cover 3, wherein the pin assembly 1 is arranged between the upper cover 2 and the lower cover 3, the upper cover 2 and the lower cover 3 are detachably connected, the pin assembly 1 can extend out of the lower cover 3 to be connected with a power supply, and the pin assembly 1 can be retracted into the lower cover 3 so as to be carried by a user.

Referring to fig. 2 and 3, fig. 3 is a schematic structural diagram of a plug connector and a rotating shaft according to an embodiment of the present disclosure. The pin assembly 1 comprises a mounting seat 12, a rotating shaft 15 and a plug connector 14, wherein the rotating shaft 15 is rotatably connected with the mounting seat 12, and the plug connector 14 is connected with the rotating shaft 15. The plug 14 includes a contact portion 142, and a first distance L1 is provided between the contact portion 142 and an axis AA of the rotating shaft 15, it is understood that, in the vertical direction, the contact portion 142 has a highest point, and a vertical distance between the highest point and the axis AA is a first distance L1, and the first distance L1 is a moving radius of the contact portion 142. When the plug 14 is in the vertical position, the contact portion 142 has a second distance L2 from a horizontal plane H on which the axis AA of the rotating shaft 15 is located, which is, as shown in fig. 3, the vertical direction is the extending direction of the plug 14, and the horizontal plane H is perpendicular to the vertical direction. In the vertical direction, the contact portion 142 has a highest point, a horizontal plane H where the axis AA is located is perpendicular to the vertical direction, the contact portion 142 is located above the horizontal plane H where the axis AA is located, a vertical distance from the highest point to the horizontal plane H is a second distance L2, and the second distance L2 is a distance between the contact portion 142 and the rotating shaft 15 in the extending direction of the plug connector 14.

Referring to fig. 4, fig. 4 is a schematic diagram of the first distance and the second distance when the plug is in the vertical position. The axis AA passes through the center of the rotating shaft 15, the length of a connecting line between the contact part 142 and the center of the rotating shaft 15 is a first distance L1, the horizontal plane where the axis AA is located is H, and the vertical distance from the contact part 142 to the horizontal plane H is a second distance L2. It will be appreciated that an excessive second distance L2 will result in a longer plug 14, and that shortening the second distance L2 will reduce the length of the plug 14. In other words, the larger the second distance L2, the "higher" the plug 14 will be, and the smaller the second distance L2, the "height" of the plug 14 can be decreased to reduce the size of the plug 14.

In the related art, the contact portion is usually disposed along the extending direction of the connector with the rotation axis, i.e., the first distance is equal to the second distance. In the embodiment of the present application, as shown in fig. 4, the contact portion 142 is disposed eccentrically from the rotating shaft 15, and a predetermined included angle (i.e., an included angle between a line connecting the contact portion 142 and the center of the rotating shaft 15 and the vertical direction) is formed between the first distance L1 and the second distance L2, so that the first distance L1 is greater than the second distance L2. Illustratively, the radius of motion is required to be 5 mm, and when the contact portion 142 and the rotation shaft 15 are disposed along the extending direction of the plug 14 (non-eccentric disposition), the first distance L1 is equal to the second distance L2, and the first distance L1 and the second distance L2 are both 5 mm. When the contact portion 142 is disposed eccentrically from the rotation shaft 15, the first distance L1 is equal to 5 mm, the second distance L2 is smaller than the first distance L1, and the second distance L2 is smaller than 5 mm, and the eccentric disposition can reduce the length of the plug 14 at the same radius of motion. It can be understood that, when the charging plug is eccentrically arranged, the larger the included angle between the vertical direction and the connecting line between the contact part 142 and the center of the rotating shaft 15 is, the larger the difference between the first distance L1 and the second distance L2 is, the smaller the size of the plug connector 14 is, and thus the thickness of the charging plug 100 is reduced, which is convenient for a user to carry.

As shown in fig. 2, the lower cover 3 is detachably connected to the mounting base 12, and for example, the lower cover 3 is screwed to the mounting base 12, but the lower cover 3 and the mounting base 12 may be connected in other manners as well, which is not limited herein. The lower cover 3 is provided with an outlet hole 32, and the rotary shaft 15 is disposed in the outlet hole 32 so that the plug 14 can extend out of the lower cover 3. The lower cover 3 is provided with a receiving groove 31 on a surface departing from the upper cover 2, when the plug 14 is located at a vertical position, the extending direction of the plug 14 is perpendicular to the extending direction of the receiving groove 31, and the plug 14 can extend out of the lower cover 3. When the connector 14 is in the horizontal position, the extending direction of the connector 14 is parallel to the extending direction of the accommodating slot 31, and the connector 14 can be accommodated in the accommodating slot 31 for the user to carry.

Referring to fig. 5 and 6, fig. 5 is a schematic structural diagram of the connector in a vertical position, and fig. 6 is a schematic structural diagram of the connector in a horizontal position. The pin assembly 1 further comprises a spring plate 18 and a reduced-size spacer 16, wherein the spring plate 18 is connected with the mounting seat 12, and the contact part 142 can abut against the spring plate 18. The edge portion of the reduced-size isolation portion 16 extends out of the plug connector 14, and the reduced-size isolation portion 16 is connected with the rotating shaft 15 and rotates along with the rotating shaft 15, so as to realize the contact or separation of the elastic sheet 18 and the contact portion 142. Illustratively, the contact portion 142 contacts the spring 18 when the plug 14 is in the vertical position, and the separation portion 16 is disposed between the spring 18 and the plug 14 to separate the spring 18 from the plug 14 when the plug 14 is in the horizontal position.

The resilient member 18 includes a first sub-portion 181 and a second sub-portion 182, the first sub-portion 181 is connected to the second sub-portion 182, and the first sub-portion 181 and the second sub-portion 182 form a predetermined angle. The first sub-portion 181 is used to connect to the mounting base 12, the second sub-portion 182 extends from the first sub-portion 181 with a certain elasticity, and the second sub-portion 182 is used to abut against the contact portion 142. When the connector 14 is in the vertical position, the first sub-portion 181 is disposed above the contact portion 142, the second sub-portion 182 is disposed at one side of the contact portion 142, and the contact portion 142 abuts against the second sub-portion 182, so that the connector 14 can be inserted into a socket to complete charging. When the connector 14 is in the horizontal position, the separating portion 16 is disposed between the second sub-portion 182 and the connector 14, and the connector 14 is recycled for the user to carry.

The isolation part 16 at least partially wraps the rotating shaft 15, and the outer surface of the isolation part 16 comprises a first surface 162, an isolation surface 161 and a second surface 163, wherein the isolation surface 161 connects the first surface 162 and the second surface 163. The isolation surface 161 is located outside the plug connector 14, the first surface 162 is located in a region between the rotating shaft 15 and the contact portion 142, and a projection of the first surface 162 is located inside the plug connector 14. It is understood that when the first surface 162 is located outside the plug 14, the first surface 162 may interfere with the spring plate 18, and in order to avoid the interference between the first surface 162 and the spring plate 18, the movable range of the spring plate 18 needs to be enlarged, which also results in an increase in the overall size of the charging plug 100. The projection of the first surface 162 is located in the plug 14, so that the interference between the first surface 162 and the resilient piece 18 can be avoided, and the effect of reducing the size can be achieved. Accordingly, the projection of the second surface 163 may also be located in the plug 14, which serves to reduce the size of the separating portion 16, and thus the thickness of the charging plug 100, so as to facilitate carrying by the user.

As shown in fig. 6, a third distance L3 exists between the isolation surface 161 and the axis AA of the rotating shaft 15, and the third distance L3 is smaller than or equal to the first distance L1. The spacer 16 may lift the spring 18 to separate the spring 18 from the contact 142. The third distance L3 is less than or equal to the first distance L1, so that the elastic sheet 18 is prevented from being pushed too high by the separating part 16, the moving space of the elastic sheet 18 is prevented from being increased, and the function of reducing the overall size of the charging plug 100 is achieved.

It can be understood that the spacer 16 is used to lift the elastic sheet 18, when the size of the spacer 16 is too small, the strength of the spacer 16 may be poor, and the elastic sheet 18 may crush the spacer 16, so that the thickness of the spacer 16 may be increased appropriately. For example, the first surface 162 may be convex in a direction away from the rotating shaft 15, and the second surface 163 may also be convex in a direction away from the rotating shaft 15, so as to increase the thickness of the reduced-size separating portion 16 and improve the strength. When the plug 14 is located in the horizontal position, the isolation surface 161 should be at the highest point to isolate the elastic piece 18 from the plug 14, and the second surface 163 may be parallel to the fourth side 1413, so as to ensure that the height of the second surface 172 is not greater than the height of the isolation surface 161, and increase the thickness of the isolation portion 16 to the maximum extent without increasing the movement space of the elastic piece 18.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a plug connector in an embodiment of the present application. The plug 14 further includes a pin 141, the pin 141 includes a third side 1412 and a fourth side 1413 which are oppositely disposed, the third side 1412 and the fourth side 1413 are symmetrical with respect to the center line CC, and the contact portion 142 can be symmetrically disposed with respect to the center line CC, it can be understood that the symmetrical disposition facilitates the manufacturing of the plug 14. Referring to fig. 3, the axis AA of the rotating shaft 15 may be disposed on a side of the center line CC close to the fourth side 1413, so that the contact portion 142 is disposed eccentrically to the rotating shaft 15. The third side 1412 is transitionally connected with the contact portion 142 through the first side 144, and the fourth side 1413 is transitionally connected with the contact portion 142 through the second side 145.

It should be noted that the first side surface 144 is recessed toward a direction away from the elastic sheet 18. When the plug 14 is in the vertical state, the first side surface 144 can avoid the second sub-portion 182 of the elastic piece 18, so as to prevent the other parts of the plug 14 except the contact portion 142 from contacting the elastic piece 18, thereby avoiding potential safety hazards.

Referring to fig. 8, fig. 8 is a schematic structural diagram of a rotating shaft, an isolating portion and a limiting portion in an embodiment of the present application. The isolation portion 16 is provided with a mounting groove 164, an opening of the mounting groove 164 faces the second side surface 145, the plug 14 is disposed in the mounting groove 164, and the second side surface 145 is attached to a bottom wall of the mounting groove 164, so that the isolation surface 161 is disposed opposite to the second side surface 145. It should be noted that the second side surface 145 may be recessed in a direction away from the isolation surface 161, so that a space between the second side surface 145 and the isolation surface 161 is increased, which may serve to increase the thickness of the isolation portion 16.

For example, as shown in fig. 4 and 7, the overall height of the plug 14 may be 25 mm, the second distance L2 from the hinge 15 to the contact portion 142 is 5 mm, and the distance from the center line of the hinge 15 to the fourth side 1413 is 2.5 mm. The height of the partition 16 in the extending direction of the plug 14 is 5.1 mm, and the specific dimensions of the components are not limited thereto.

Referring to fig. 8 and 9 in combination, fig. 9 is a schematic exploded view of a pin assembly according to an embodiment of the present application. The plug-in unit 14 and the rotating shaft 15 can rotate around the axis AA of the rotating shaft 15, and when the plug-in unit 14 is located at a horizontal position, the plug-in unit 14 needs to be prevented from rotating to a vertical position. When the plug 14 is in the vertical position, it is desirable to avoid rotating the plug 14 to the horizontal position. Therefore, the stopper 17 may be provided on the rotating shaft 15 and the tongue piece 13 may be provided on the mounting seat 12. The stopper 17 includes a first surface 171 and a second surface 172, the first surface 171 is connected to the second surface 172, and the first surface 171 is perpendicular to the second surface 172. When the plug 14 is located at the vertical position, the tongue piece 13 abuts against the first surface 171 to apply an abutting force to the rotation shaft 15, so that the plug 14 is prevented from rotating from the vertical position to the horizontal position. When the plug 14 is in the horizontal position, the tongue 13 abuts against the second surface 172 to limit the rotation of the plug 14 to the vertical position.

As shown in fig. 7 and 8, the connector 14 is provided with a connection hole 143, the connection hole 143 may be symmetrically disposed about the center line CC, and the connection hole 143 may also be disposed at other positions on the connector 14, which is not limited herein.

Illustratively, the connection hole 143 may be a non-circular hole, and the connection segment 151 has a cross-section having the same shape as the connection hole 143. It can be understood that the non-circular hole can prevent the connecting segment 151 from rotating relative to the connecting hole 143, thereby improving the connection between the connecting segment 151 and the plug 14.

The number of the plug connectors 14 is two, and the two plug connectors 14 are respectively connected with a live wire or a zero wire. Accordingly, the charging plug 100 is provided with two spring pieces 18, and one spring piece 18 is arranged corresponding to one plug connector 14.
