Problems solved by technology

Although this solves the miniaturization problem of products such as mobile power supplies, but it brings a special wire, which has no standard products after damage, which is even more unfavorable for the light, convenient and simple design of the product.
[0004] The above problems have an unavoidable impact on small mobile devices, especially on miniaturized mobile power devices, such as USB rechargeable batteries, lighter mobile power supplies, rechargeable multi-purpose U disks, etc. Due to their small size, two The plug cannot be realized at all, which is one of the core factors that have not seen the launch of USB battery products that can be charged and discharged in the same body.
[0005] At present, there is no one used on the size interface of USB Type A and USB Type B in the market. It can not only be used as a male plug to be inserted into the female plug that provides power to receive current, but also can be used as a female plug to provide current to be used by others. Product or design for male plug-in

Embodiment 1

[0062] Embodiment 1: as Figure 1-13 As shown, the hermaphrodite charging and discharging USB connection plug (Androgynous USB connector, hereinafter referred to as AUC) provided in this embodiment includes:

[0063] PCB board 1, the gold finger 11 corresponding to the shrapnel of the USB female head 4 is provided on the front of the PCB board 1, and the charging circuit is provided on the back of the PCB board 1, and the charging circuit includes a trigger part 12 for controlling the on and off of the charging circuit, and the trigger part 12 wears Protrude through the PCB board 1 and set on the front of the PCB board 1; the charging circuit is used to charge the USB male head when the USB connection plug is used as a female head. In this embodiment, the charging circuit is arranged on the back of the PCB board to save connection joints occupied space. Of course, in order to simplify the process, the charging circuit can also be arranged outside the frame. As long as the fun...

Embodiment 2

[0067] Embodiment 2: Different from other embodiments, such as Figure 4-7 As shown, the gold finger 11 includes a first gold finger 111 connected to the input ground terminal 13, a second gold finger 112 connected to the input data negative terminal 14, a third gold finger 113 connected to the input data positive terminal 15, and a The fourth gold finger 114 connected to the input power terminal 16; the trigger component 12 includes two trigger elements 121, and the two trigger elements 121 are respectively arranged between the first gold finger 111 and the second gold finger 112 and between the third gold finger 113 and the second gold finger 112. Between the fourth gold fingers 114 ; the front of the PCB 1 is provided with a through hole 17 for accommodating the trigger element 121 . The golden finger 11 corresponds to the metal elastic piece inside the USB female connector 4 , and serves as a conductive path for input current when connected to the USB female connector 4 . ...

Embodiment 3

[0068] Embodiment 3: Different from other embodiments, such as figure 2 , 3 As shown in and 11 , the output power spring 212 and the output ground spring 213 are bent and protrude from the back of the tongue insert 21 . The function of the output power shrapnel 212 and the function of the output wire shrapnel are equivalent to the functions of the power shrapnel and the ground wire shrapnel in the metal shrapnel of the USB male head 5, which are used as the ground wire end and the current output end of the charging circuit to ensure that the charging circuit When it is turned on, current can be output from the output power shrapnel 212 to realize the charging (current output) function of the AUC.

Abstract

The invention discloses a USB connection plug. The front face of a PCB is provided with a gold finger corresponding to an elastic sheet of a USB female connector; a charging circuit is used for charging a USB male connector when the USB connection plug is used as the female connector; the charging circuit comprises a triggering part; the triggering part passes through the PCB and is convexly arranged on the front face of the PCB; a skeleton comprises a tongue insertion body matched with jack shapes of the USB female connector and the USB male connector, and a fixed boss arranged at the fixed end of the tongue insertion body; the front face of the tongue insertion body is provided with a board groove for accommodating the PCB; the back face of the tongue insertion body is provided with an output power elastic sheet corresponding to a power gold finger of the USB male connector and an output ground wire elastic sheet corresponding to a ground wire gold finger of the USB male connector; the fixed end of the tongue insertion body is connected with an output power control terminal and an output ground wire terminal; the output ground wire terminal is connected with the output ground wire elastic sheet; one end of a positioning shell coats the fixed boss, and the other end of the positioning shell is parallel to the tongue insertion body and an interval exists between the two. The invention provides an androgynous USB connector.

Description

technical field [0001] The invention relates to the technical field of electronic transmission accessories, in particular to a USB connection plug. Background technique [0002] In various portable devices, small or miniature connectors that provide small currents are commonly used, such as USB-A, MRusb, MINIusb, Svideo, etc., which can provide 5-12V voltage and current power within 3A. Handheld small devices provide charging current. Many devices such as mobile phones and mobile power supplies charge the built-in battery of the mobile power supply through the 5V power supply of several hundred mA to several A currents provided by USB. [0003] These small mobile power devices with built-in batteries need to be charged first and then discharged in a two-way process during use, which makes the mobile power supply must be equipped with two types of connectors, one is a male connector, and the other is a male connector. It is used to plug into the female head that can provide...
