DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0024] like Figures 1 to 4As shown, a multifunctional connector provided by the present invention comprises a housing 1, a first connector 2, a second connector 3, a first terminal group 4 arranged in the first connector 2 and a second terminal group 5 arranged in the second connector 3, the first connector 2 is installed in the housing 1, the second connector 3 is movably arranged in the housing 1, the first connector 2 is used as an independent connector, and the second connector 3 is used as another independent connector when matched with the first connector 2; the first terminal group 4 comprises a first power connection terminal 41, a first channel terminal 42, a first data terminal 43, a second data terminal 44 and a second power connection terminal 45 arranged side by side, and the second terminal group 5 comprises a third power connection terminal 51, a third data terminal 52, a fourth data terminal 53 and a fourth power connection terminal 54 arranged side by side;

[0025] Specifically, the first data terminal 43 is provided with a first extension portion 431, and the second data terminal 44 is provided with a second extension portion 441. When the second connector 3 is matched with the first connector 2, the first power terminal 41 and the third power terminal 51, the first extension portion 431 and the fourth data terminal 53, the second extension portion 441 and the third data terminal 52, and the second power terminal 45 and the fourth power terminal 54 are in one-to-one contact.

[0026] Specifically, the second joint 3 is rotatably connected to the housing 1 , and the first joint 1 is embedded in the second joint 3 so as to be used as the other independent joint.

[0027] The first connector 2 of the present invention is a TYPE-C connector, and the second connector 3 is a USB connector, that is, when the second connector 3 is covered on the first connector 2 so that the first connector 2 is embedded in the second connector 3, the second connector 3 cooperates with the first connector 2 to be used as a USB connector. In actual use, the first data terminal 43 and the second data terminal 44 of the TYPE-C connector cooperate to realize data transmission, and the polarity of the first data terminal 43 and the second data terminal 44 is opposite to that of the third data terminal 52 and the fourth data terminal 53, which results in: when the third data terminal 52 abuts against the first data terminal 43, and the fourth data terminal 53 abuts against the second data terminal 44, that is, as in the Chinese invention patent with application number "201710988051.3", the effect of data transmission cannot be achieved. Therefore, the present invention leads out the first extension portion 431 at the first data terminal 43 to contact the fourth data terminal 53, and leads out the second extension portion 441 at the second data terminal 44 to contact the third data terminal 52, so that when in the USB connector state, the first data terminal 43 is connected to the fourth data terminal 53, and the second data terminal 44 is connected to the third data terminal 52, thereby achieving data transmission and charging effects regardless of whether the present invention is in the TYPE-C connector state or the USB connector state, making the use of the present invention more comprehensive and improving the user experience.

[0028] In this embodiment, the first data terminal 43 includes a first main portion 432 and a first contact portion 433, the first main portion 432 is disposed in the first connector 2, the first contact portion 433 and the first extension portion 431 are both disposed at the same end of the first main portion 432, the first contact portion 433 is located directly below the third data terminal 52, and the first extension portion 431 is located directly below the fourth data terminal 53. That is, when used as a TYPE-C connector, the first terminal group 4 is in contact with the external interface to achieve data interaction. At this time, the first contact part 433 is used to make electrical contact with the interface of the mobile terminal, and the second terminal group 5 is in an open circuit state due to no contact, thereby achieving the effect of data transmission; and when it needs to be used as a USB connector, data transmission is achieved through the second terminal group 5 with the external interface, and the first contact part 433 is in an open circuit state, so that the first extension part 431 is connected with the fourth data terminal 53, that is, the corresponding data current of the interface is transmitted to the other terminal after passing through the fourth data terminal 53, the first extension part 431, and the first main part 432, thereby achieving the transmission effect.

[0029] Specifically, the specific structure of the second data terminal 44 is substantially the same as that of the first data terminal 43, that is, the second data terminal 44 includes a second main portion 442 and a second contact portion 443, the second main portion 442 is disposed in the first connector 2, the second contact portion 443 and the second extension portion 441 are both disposed at the same end of the second main portion 442, the second contact portion 443 is located directly below the fourth data terminal 53, and the second extension portion 441 is located directly below the third data terminal 52. The effects thereof are similar to those of the first data terminal 43, and therefore will not be described in detail herein.

[0030] Preferably, a first avoidance gap 434 is provided between the first main portion 432 and the first extension portion 431, a second avoidance gap 444 is provided between the second contact portion 443 and the second extension portion 441, the second extension portion 441 is located in the first avoidance gap 434, and the first extension portion 431 is located in the second avoidance gap 444. Since the positions of the first data terminal 43, the second data terminal 44, the third data terminal 52 and the fourth data terminal 53 are basically fixed (due to the current universal interface), the first avoidance gap 434 and the second avoidance gap 444 are provided to make the internal structure of the first terminal group 4 of the present invention more compact while ensuring that no short circuit occurs, thereby saving the internal space of the present invention.

[0031] In this embodiment, the present invention further includes a third terminal group 6 disposed in the first connector 2, the third terminal group 6 including a fifth power connection terminal 61 and a sixth power connection terminal 62; when the first connector 2 is inserted into an external interface, the fifth power connection terminal 61 contacts the first power connection terminal 41, and the sixth power connection terminal 62 contacts the second power connection terminal 45. The fifth power connection terminal 61 and the sixth power connection terminal 62 are provided to reduce the resistance value by increasing the width and thickness of the "path" for connecting electricity, so that more current passes through per unit time, so as to achieve a fast charging effect.

[0032] Specifically, the third terminal group 6 also includes an elastic component, which is used to keep the first channel end 42, the first data end 43 and the second data end 44 in reliable contact with the external socket when the first plug is plugged into the socket. In this embodiment, the elastic component is three elastic terminals 63, which only contact with the corresponding terminals, and the other end is in an insulating state to ensure that no electrical conduction occurs; the elastic terminal 63 is mainly used to lift the corresponding first data end 43 or the second data end 44 or the first channel end 42 when the present invention is connected to the external socket to ensure reliable contact with the corresponding position of the external interface, thereby avoiding the corresponding end from losing elasticity after a long time of use and being unable to achieve contact, thereby ensuring electrical conduction. In addition, the fifth power connection end 61 and the sixth power connection end 62 in the present invention also play the corresponding elastic lifting function, thereby ensuring that the charging effect can be reliably achieved. In addition, the elastic terminal 63 corresponding to the first channel end 42 can be short-circuited, or used as a spare channel to be electrically connected with the external electrical conductor. It can be adjusted conventionally according to actual needs, and will not be repeated here.

[0033] In this embodiment, the second connector 3 includes a shielding shell 31 and an insulating base 32 installed in the shielding shell 31, the shielding shell 31 is rotatably connected to the shell body 1, the second terminal group 5 is installed on the insulating base 32, the shielding shell 31 is respectively provided with mounting grooves 311 on both sides, the insulating base 32 is respectively provided with mounting blocks 321 on both sides, and the tail end of the mounting block 321 is provided with an inclined surface 322, and the inclined surface 322 is used to slide into the mounting groove 311.

[0034] That is, when assembling the second connector 3, the second terminal group 5 is first installed on the insulating base 32, and then the insulating base 32 is installed in the shielding shell 31, so that the mounting block 321 slides into the mounting groove 311 along the inclined surface 322. When the mounting block 321 completely slides into the mounting groove 311, since there is no inclined surface 322 at the front end of the mounting groove 311, the mounting block 321 cannot slide out of the mounting groove 311 by itself, thereby achieving the effect of stable and fast assembly and avoiding self-detachment.

[0035] Specifically, grooves 312 are respectively provided on both sides of the front end of the shielding shell 31, and protrusions 323 are respectively provided on both sides of the front section of the insulating base 32. The protrusions 323 are installed in the grooves 312 to prevent the insulating base 32 from being inserted too deeply into the shielding shell 31, thereby achieving a positioning effect and ensuring that after the insulating base 32 is installed, the position of the second terminal group 5 is aligned with the position of the first terminal group 4, so that both the interference effect and the external connection effect are guaranteed.

[0036] Specifically, the inner walls on both sides of the shielding shell 31 are respectively provided with card blocks 313, and the two sides of the first connector 2 are respectively provided with card slots 22, and the card blocks 22 are used to be inserted into the card slots 313, so that when the present invention is in the use mode of the USB connector, the second connector 3 will not detach from the second connector 2 by itself, thereby ensuring the stability of the present invention.

[0037] In this embodiment, the housing 1 and the first joint 2 are integrally formed, thereby ensuring the strength of the present invention.

[0038] In this embodiment, an insulating sleeve 21 is provided in the first joint 2, the first terminal group 4 and the third terminal group 6 are both installed in the insulating sleeve 21, and the first terminal group 4 protrudes out of the insulating sleeve 21 from the top of the insulating sleeve 21 and contacts the second terminal group 5.
