Description

Technical Field

[0001] This utility model relates to the field of digital accessories technology, specifically to a USB interface connector, a USB fast charging cable, and a bag. Background Technology

[0002] This section introduces background technology that may be related to various aspects of the embodiments of this utility model, which is believed to provide useful background information to help readers better understand the various aspects of the embodiments of this utility model. Therefore, it is understood that the description in this section is for the above purposes and does not constitute an admission of the prior art.

[0003] With the development of social technology and the rise of the internet, people's living standards are constantly improving, and life is gradually becoming more intelligent. The emergence of the internet has changed people's lives; using tablets and mobile phones has become a fashionable lifestyle and an indispensable part of daily life. Functions such as mobile payment, mobile navigation, mobile photography, and mobile chatting have made life more convenient and are widely used. These functions all consume a lot of battery power, therefore, people's demands for mobile phone battery life are increasing. The charging needs of electronic products are also constantly rising, and people carry charging equipment when traveling.

[0004] Currently, users typically use power banks to extend their phone's battery life. While charging, users often place the power bank in their bags for convenience. However, due to the bag's structure, the charging cable between the power bank and the phone must protrude from the bag's opening, making it difficult to close completely and reducing security. Placing the charging device in a small carry-on bag is cumbersome, while keeping it in a suitcase is inconvenient for easy access. With technological advancements, power banks are now integrated into bags. Some bags incorporate power banks internally, with the interface on the side, allowing users to use the device without removing it. However, existing adapters or extension cables are typically simple USB interfaces or USB + Micro connectors, offering only 1A slow charging. They do not support fast charging or the charging requirements of Type-C iOS phones, failing to meet charging needs. Utility Model Content

[0005] The technical problem to be solved is how to provide a USB interface connector and a USB fast charging cable.

[0006] To address the shortcomings of existing technologies, this utility model provides a USB interface connector and a USB fast charging cable, which has a simple structure and can achieve fast charging.

[0007] In a first aspect, this utility model provides a USB interface connector, comprising: a connector body, wherein a circuit board and a terminal fixing seat are disposed within the connector body, and the terminal fixing seat is provided with Vbus, GND, D+, and D- terminals; one end of the circuit board is connected to the Vbus, GND, D+, and D- contact terminals, and the other end is connected to a data transmission line;

[0008] It also includes a switching mechanism located inside the female connector body. The metal shell of the male connector of the device is connected or disconnected from the GND terminal through the switching mechanism to trigger or turn off the fast charging mode of the male connector.

[0009] In some other embodiments of the USB interface connector provided in this specification, the switching mechanism includes a spring contact connected to the GND terminal. After the male connector of the connecting device is inserted into the female connector body of the USB interface connector, the connector is deformed by the plug pressing the spring contact, causing a portion of the spring contact to make contact with the metal shell of the male connector to conduct electricity.

[0010] In some other embodiments of the USB interface connector provided in this specification, the spring contact and the GND terminal are integrally formed.

[0011] In some other embodiments of the USB interface connector provided in this specification, the spring contactor's GND terminal is elongated and bent to form a spring contact mechanism, and the end of the contact mechanism is provided with a bent contact.

[0012] In some other embodiments of the USB interface connector provided in this specification, the spring includes a root portion communicating with the circuit board, a fixing portion parallel to the terminal fixing base, and a bent contact connected to the GND terminal of the male connector. The end of the spring is provided with a conductive switch contact that extends beyond the terminal fixing base and contacts the metal shell of the male connector to conduct electricity.

[0013] In some other embodiments of the USB interface connector provided in this specification, the circuit board is fixedly installed inside a protective housing, and the protective housing is further provided with a sealing cover to seal the circuit board.

[0014] In some other embodiments of the USB interface connector provided in this specification, the terminal fixing base is provided with a notch at the corresponding position of the switching mechanism, so that the switching mechanism generates a switching action in the notch, causing the switching mechanism to connect or disconnect the GND terminal with the metal shell that triggers or closes the male connector.

[0015] Secondly, this utility model embodiment also provides a USB fast charging cable, characterized in that it includes a cable input end and a cable output end, and a transmission cable is connected between the cable input end and the cable output end;

[0016] The cable output end is equipped with the aforementioned USB interface connector.

[0017] Thirdly, this utility model embodiment also provides a bag with USB fast charging, including a cable input end and a cable output end, wherein a transmission cable is connected between the cable input end and the cable output end;

[0018] The cable output end is equipped with the aforementioned USB interface connector.

[0019] As can be seen from the above technical solution, a USB interface connector for connecting a female connector and a USB fast charging cable, through a switching mechanism disposed within the female connector body, allows the metal shell of the male connector to connect or disconnect the GND terminal via the switching mechanism, thereby triggering or deactivating the fast charging mode of the male connector. This solves the problem of ensuring that the functionality of a standalone USB Type-A female connector or a standalone Type-C female connector remains unaffected in many low-cost scenarios. For example, in some simple charging port adapters, it ensures that the functionality is unaffected when either the Type-C female connector or the USB female connector is used alone, while still outputting a standard 5V power supply when used together, greatly simplifying the circuit and significantly reducing costs.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Currently, Type-C and USB A connectors are widely used in data cables in the digital electronics industry. To meet the diverse usage scenarios of customers, a device's Type-C female connector needs to be expanded to require both USB A connectors and Type-C interfaces for output. While the USB A female connector itself has a standard power output between its positive and negative ground (GND), the Type-C female connector requires a pull-up or pull-down resistor to divide the voltage at the CC pin (PD) of the Type-C connector in the circuit to achieve power output or input at the positive and negative terminals. Therefore, if a device needs to use both types of female connectors simultaneously, complex circuitry is required to implement their respective functions.

[0036] like Figure 1 As shown, the existing USB connector is a one-to-two converter circuit with a TYPE-C male connector P1 as the input and a USB A female connector P2 and a TYPE-C female connector P3 as the outputs. The positive and negative terminals of the TYPE-C male connector P1 are connected to the positive and negative terminals of the USB A female connector P2 and the TYPE-C female connector P3, respectively. The CC pin of the TYPE-C male connector P1 is connected to the CC pin, and a pull-down resistor R1 with a resistance value of 5.1K is connected to the CC pin. The other end of the resistor is connected to the metal shell of the USB A female connector, and the shell of the USB A female connector P2 is not connected to ground GND.

[0037] like Figure 2 As shown, in another existing USB connector, the TYPE-C male connector P1 is used to connect to the power source, for example, when plugged into the TYPE-C female connector P4 of a standard USB charger. When neither the USB A female connector P2 nor the TYPE-C female connector P3 is connected to an output device, there is no power output in the circuit. When the device's TYPE-C male connector P5 is plugged into the TYPE-C female connector P3, the CC pin of the TYPE-C male connector P5 in the device connects with the CC pin of the TYPE-C male connector P1, achieving standard PD communication and thus providing power output.

[0038] like Figure 3As shown, in another existing USB connector, when the USB Type-A female connector P2 is connected to a device through the USB Type-C male connector P6, theoretically, the outer shell of the USB Type-A male connector P6 in the connected device is connected to the ground wire GND, which is equivalent to grounding R1 (5.1K). This forms a 5.1K pull-down resistor from the CC pin of the TYPE-C male connector to GND. In the specification of the USB TYPE-C protocol, the OTG function is implemented, so the PD power supply will output 5V 2A power. However, after our USB Type-A male connector is unplugged, because one end of R1 is left floating and there is no actual pull-down resistor connected to the TYPE-C male connector P1, the OTG function is lost. Therefore, the normal TYPE-C transmission function of the TYPE-C male connector P1 and the TYPE-C female connector P3 is still guaranteed. However, in actual applications, the outer shell of many TYPE-C male connectors is not grounded, so R1 (5.1K) cannot be grounded. This causes the pull-down to fail, thus preventing the USB A male P6 from pulling down the CC PIN to ground (GND) via R1 (5.1K), and thus preventing the OTG function from being achieved.

[0039] like Figure 4 As shown, structural analysis of the USB Association's standard USB A female connector reveals that the standard USB 2.0 standard USB A female connector consists of a metal casing 1, a plastic core 2, and four contact pins 3, which are defined as P1 for VCC, P2 for D-, P3 for D+, and P4 for GND.

[0040] like Figures 5 to 13 As shown, this utility model embodiment provides a USB interface connector, including: a connector body 4, a circuit board 5 and a terminal fixing base 6 disposed within the connector body 4, the terminal fixing base 6 being provided with Vbus, GND, D+, and D- contact terminals 7; one end of the circuit board 5 is connected to conduction Vbus, GND, D+, and D- contact terminals 7, and the other end is connected to a data transmission line; it also includes a switching mechanism 47 disposed within the connector body 4, the metal shell 90 of the male connector 9 of the connecting device is connected or disconnected from the GND terminal through the switching mechanism 47 to trigger or deactivate the fast charging mode of the male connector 9. The following is a detailed description of the USB interface connector provided by this utility model embodiment.

[0041] like Figures 5 to 13As shown in this embodiment of the invention, the switching mechanism 47 includes a spring piece 71 connected to the GND terminal. After the male connector 9 of the connecting device is inserted into the female connector body 4 of the USB interface connector, the connector 9 squeezes the spring piece 71, causing it to deform and a portion of the spring piece 71 to contact the metal shell 90 of the male connector 9 to conduct electricity. The spring piece 71 is integrally formed with the GND terminal. The spring piece 71 and the GND terminal are lengthened and bent to form a spring-type contact mechanism, and the end of the contact mechanism is provided with a bent contact 73.

[0042] In the embodiments of this utility model, such as Figures 6 to 13 As shown, the spring 71 includes a root 70 communicating with the circuit board, a fixing part 72 parallel to the terminal fixing seat, and a bent contact 73 connected to the GND terminal of the male connector. The end of the spring 71 is provided with a conducting switch contact 75 that passes through the terminal fixing seat 6 and contacts the iron shell 90 of the male connector 9 to conduct electricity.

[0043] In the embodiments of this utility model, such as Figures 6 to 10 As shown, the circuit board 5 is fixedly installed inside the protective shell, and the protective shell is also provided with a sealing cover to seal the circuit board 5.

[0044] like Figures 5 to 13 As shown in this embodiment of the utility model, the terminal fixing seat 6 is provided with a notch 60 at the corresponding position of the switching mechanism 4, so that the switching mechanism 47 generates a switching action in the notch 60, so that the switching mechanism, together with or disconnects the GND terminal from the iron shell 90 that triggers or closes the male connector 9.

[0045] In this embodiment of the present invention, to further demonstrate the advanced nature of the USB interface connector provided by the present invention, this embodiment of the present invention also provides a USB fast charging cable, including a cable input end and a cable output end, wherein a transmission cable is connected between the cable input end and the cable output end; the cable output end is provided with the aforementioned USB interface connector.

[0046] In this embodiment of the present invention, to further demonstrate the advanced nature of the USB interface connector provided by the present invention, this embodiment of the present invention also provides a bag with USB fast charging, including a cable input end and a cable output end, wherein a transmission cable is connected between the cable input end and the cable output end; the cable output end is provided with the aforementioned USB interface connector.

[0047] In summary, this utility model provides a USB interface connector, a USB fast charging cable, and a bag. Through a switching mechanism located within the connector body, the metal shell of the male connector of the connected device connects or disconnects the GND terminal via the switching mechanism to trigger or deactivate the fast charging mode of the male connector. This solves the problem of ensuring the functionality of a standalone USB-A or standalone Type-C female connector remains unaffected in many low-cost scenarios. For example, in some simple charging port adapters, it ensures that the functionality is unaffected when either the Type-C or USB female connector is used alone, while still outputting a standard 5V power supply when used together, greatly simplifying the circuit and significantly reducing costs.
