[0043] In order to make the objects, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0044] Reference Figures 1 to 6 The charging connector provided by the embodiments of the present application comprises: a charging head unit 3, two ends of which are respectively a first charging head 301 and a second charging head 302; a connecting assembly, which is provided with a protective end 201; the charging head unit 3 is rotatably connected to one side of the connecting assembly, and the rotating track makes the first charging head 301 or the second charging head 302 at least partially locatable in the protective end 201; and the connecting assembly is provided with a first circuit board 101 electrically connected to the first charging head 301 and the second charging head 302.

[0045] In the present application, the connecting assembly is provided with the protective end 201, when one of the first charging head 301 and the second charging head 302 is located in the protective end 201, the other one protrudes from the other end of the connecting assembly; during charging, according to the type of the device, the first charging head 301 or the second charging head 302 is selected, one of the two is used to connect the device, and the other one is located in the protective end 201, which can hide and protect the unused connecting head, and can avoid collision or heavy pressure damage to the connecting head; not only solves the problem that the unused charging head is completely exposed and easy to be damaged in the prior art, but also improves the stability of the electrical connection without conversion of the charging head and the device, and guarantees the stability of charging or data transmission whether for charging or data transmission.

[0046] Below, one of the charging connectors in the exemplary embodiments of the present application will be further described.

[0047] In the embodiment of the present application, the connection assembly of the charging connector comprises: a first housing 1, a second housing 2 is arranged on the upper cover of the first housing 1; the upper end of the second housing 2 is rotatably and tightly connected to the charging head unit 3; the second housing 2 is provided with a protective end 201 which is inwardly bent, so that the protective end 201 forms a structure similar to a "U" shape, and the opening faces inward; when the charging head unit 3 is rotated, the first charging head 301 and the second charging head 302 can be located in the protective end 201.

[0048] In addition, based on the above scheme, a rubber end cover (not shown in the figure) can also be used. When not in use, one connector is located in the protective end 201 and the other is located outside, and the end cover can be covered. When in use, the end cover can be covered on the connector located in the protective end 201, so that the charging connector can be protected to the maximum extent.

[0049] In the embodiment of the present application, the charging head unit 3 is further provided with a second circuit board 303; the first charging head 301 and the second charging head 302 are respectively located at the two ends of the second circuit board 303; the second circuit board 303 is provided with a centering column 304 in the middle, and at least two conductive rings 305 are concentrically arranged around the centering column 304; the conductive rings 305 are electrically connected to the first charging head 301 and the second charging head 302; the second housing 2 is provided with a first through hole 202; the centering column 304 and the first circuit board 101 are rotatably connected; the first circuit board 101 is further provided with at least two elastic conductive columns 106; the end of the elastic conductive column 106 abuts against the conductive ring 305. The at least two elastic conductive columns 106 correspond to the at least two conductive rings 305; the conductive rings 305 are nested inside and outside the second circuit board 303 and are concentrically arranged, and are used to connect the charging pins of the first charging head 301 and the second charging head 302; at least one elastic conductive column 106 is connected to each conductive ring 305, so that the charging head is not limited by rotation, and the two charging heads always maintain electrical connection with the first circuit board 101, and the first circuit board 101 is used to be electrically connected to the charger through the corresponding charging wire. The problem that the internal wire cannot be continuously rotated is solved, and the wire is connected in the current technology. Because the wire cannot be extended unlimitedly, when the two parts are rotated to a certain angle, it is necessary to reverse to make the internal wire return to the original position, otherwise the wire will be pulled off due to continuous rotation. The present application can be rotated unlimitedly and keep conduction. In addition, the elastic conductive column 106 is movable at the top and bottom and has elasticity, so that the elastic conductive column 106 is always electrically connected to the conductive ring 305 during rotation, ensuring the reliability of electrical connection and preventing disconnection due to stress during rotation.

[0050] Further, at least two of the conductive columns 106 are symmetrically connected to the center of each of the conductive rings 305. The symmetrically arranged conductive columns 106 can balance the stress of the conductive columns 106 and make the connection of the conductive columns 106 and the conductive rings 305 more stable.

[0051] It should be noted that the conductive columns 106 are also called conductive pins, which have elasticity at one end and can be electrically connected to the target within a certain elastic stroke. The conductive rings can also be provided with four or more, in which two are used for charging, and four or more are used for transmitting data in addition to the two for power supply, so that the connector can be used for data transmission in addition to charging, and can be combined with the cable to not only form a charging cable but also a data cable, improving its compatibility.

[0052] It should be further noted that terminal equipment manufacturers generally configure only charging cables without data transmission lines when data transmission is not required. Therefore, a general data cable can be used for charging, but a charging cable cannot be used for data transmission.

[0053] In the embodiment of the application, the upper end of the centering column 304 is connected to the first circuit board 101 through the torx screw 102. The first circuit board 101 is provided with a mounting hole, and the upper end of the centering column 304 is provided with a step which is mounted in the mounting hole, so that the charging head unit 3 can rotate relative to the first circuit board 101 through the centering column 304. The first circuit board 101 is positioned on the step through the screw hole in the centering column 304 and the torx screw 102 which connects the screw hole. The damping spring 103 is arranged around the nut of the torx screw 102. The damping spring 103 is provided with a protrusion 104 protruding inward. The damping spring 103 is fixedly connected to the first circuit board 101 through the connecting piece 105 at the lower end of the damping spring 103. The protrusion 104 of the damping spring 103 faces the nut of the torx screw 102. Since the nut is in the shape of a torx, the protrusions and depressions around the nut can generate a certain resistance when the protrusion 104 rotates when the charging head unit 3 drives the torx screw 102 to rotate, forming a rotary damping effect. The above simple structure can realize the multifunctional rotatable charging connector, and also has the advantages of low cost, easy implementation, and improved user experience.

[0054] Further, the charging head unit 3 further comprises a third shell 4; the third shell 4 is provided with a second through hole 401 in the middle; the third shell 4 is covered on the inner side of the charging head unit 3 and is arranged in close contact with the second shell 2, and the second through hole 401 is arranged concentrically with the first through hole 202. The centering column 304 and the conductive column 106 pass through the first through hole 202 and the second through hole 401; through the above structure, when the charging head unit 3 rotates, the inside will not be exposed, so that the combination of the charging head unit 3 and the connecting assembly is more compact.

[0055] Preferably, the first charging head 301 is a TYPE-C connector; and the second charging head 302 is a Lightning interface.

[0056] It should be noted that the first charging head 301 can also be a Lightning interface, and the second charging head 302 can also be a TYPE-C interface, and the two can be the same interface, or different interfaces, or a conventional USB interface (i.e. USB-A interface) or micro USB interface and other types of interfaces.

[0058] In the embodiments of the present application, based on the same concept, it is also disclosed that a charger comprises a power adapter and the above charging cable; one end of the cable 6 of the charging cable is connected with the adapter, and the other end is the above charging connector, or the adapter is provided with at least one interface that can be adapted to the above charging connector, for example, the adapter can be provided with a USB-A interface and / or a TYPE-C interface, and the charging cable with a USB-A connector connected at one end has the other end as the above rotatable connector. Or the adapter of the charger is provided with an integral cable 6, and the other end of the cable 6 is the above charging connector.
