Description

Technical Field

[0001] The present disclosure relates to the technical field of connection interfaces, and in particular to an interface, a connector, a cable, and a terminal device. Background Art

[0002] In electronic devices, interfaces and connectors play a vital role in enabling connections between different modules, so as to enable data transmission or power supply between different hardware modules or electronic devices. However, due to the electrochemical corrosion of electric current and the influence of environmental factors such as contamination, moisture, oxidation, etc., interface pins often corrode. When the interface or connector pins are affected by corrosion, their ability to transmit signals will be severely affected, or even completely lose their original functions, rendering the entire interface or connector unusable.

[0003] In the related art, the corrosion rate of the interface or connector pins is usually slowed down by electroplating anti-corrosion materials such as rhodium, ruthenium, platinum, etc. on the interface or connector pins. However, this solution is extremely expensive and can only delay the corrosion rate of the interface or connector pins to a certain extent, and the effect is not good. Summary of the invention

[0027] Optionally, the connector includes a Universal Serial Bus (USB) connector, and the plurality of connector pins include at least two of CC1, CC2, D+ and D-.

[0028] A third aspect of the present disclosure provides a cable, comprising a connecting wire and at least one connector as described in the first aspect.

[0029] Optionally, the cable includes a plurality of connectors, at least one of the plurality of connectors being the connector as described in the first aspect. Any specific pin of the other connectors among the plurality of connectors other than the connector as described in the first aspect is connected to the first connection channel.

Based on this, when the connector is connected to the interface, the device circuit will have a plurality of signal paths that can be connected to the connection line and can be used to transmit the target signal, thereby exponentially reducing the possibility of an unavailable phenomenon occurring between the device circuit and the first connection channel (for example, the unavailability probability of each pin is c, and the at least two interface pins include N interface pins, then the probability of an unavailable phenomenon occurring between the device circuit and the first connection channel in this solution is c N , where 0 < c < 1 and N is a positive integer), ensuring the availability of the interface and the connector. In addition, compared with the solution of plating anti-corrosion materials such as rhodium ruthenium and platinum on the interface or connector pins, the cost of this solution is extremely low (almost negligible). At the same time, it ensures that when some of the at least two interface pins are damaged, the device circuit and the first connection channel can still transmit the target signal, providing guarantee for signal transmission after the interface and the connector are corroded, and greatly improving the availability of the interface and the connector.

[0045] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0046] In electronic devices, interfaces and connectors play a vital role in enabling connections between different modules, so as to enable data transmission or power supply between different hardware modules or electronic devices. However, due to the electrochemical corrosion of electric current and the influence of environmental factors such as contamination, moisture, oxidation, etc., interface pins often corrode. When the interface or connector pins are affected by corrosion, their ability to transmit signals will be severely affected, or even completely lose their original functions, rendering the entire interface or connector unusable.

[0047] In the related art, the corrosion rate of the interface or connector pins is usually slowed down by electroplating anti-corrosion materials such as rhodium, ruthenium, platinum, etc. on the interface or connector pins. However, this solution is extremely expensive and can only delay the corrosion rate of the interface or connector pins to a certain extent, and the effect is not good.

[0048] In view of this, the present disclosure provides an interface, a connector, a cable and a terminal device.

[0049] A connector (also called a connector) refers to a component used to connect electronic components, circuit boards or cables, such as a USB Type-C (Universal Serial Bus Type-C, also referred to as Type-C) connector, a Micro USB connector (Micro Universal Serial Bus, micro universal serial bus interface), etc. The connector and its corresponding interface usually have a specific and mutually corresponding physical shape and pin (contact) layout, and can be used to provide or receive power and transmit data. The interface is usually mounted on an electronic device and is used to provide a connection between the device circuit (i.e., the circuit of the device where the interface is located) and the connector. In a typical scenario, the device circuit (first device)-interface-connector-connecting line-connector-interface-device circuit (second device) are connected in sequence, wherein the combination of "connector-connecting line-connector" can generally be referred to as a cable. Among them, the device circuit can be a mobile phone motherboard, a mobile phone charging chip, a charger power supply circuit, etc. It should be understood that the interface and connector involved in the present disclosure are a pair of relative concepts, and are not specific to the form, role and application scenario. In the following text, the embodiments of the present disclosure may be explained by taking the interface and connector that conform to the Type-C appearance standard as an example, but the present disclosure is not limited to the specific appearance standard (i.e., contact layout) of the interface and connector; in addition, the present disclosure is not limited to the specific shape of the interface and connector. For example, the contacts of the interface or connector can be located inside the geometric interior of the shell (i.e., as a "female head" in general), or can be located outside the geometric exterior of the shell (such as a "male head" in general, or a planar contact interface and connector).

[0050] See also Figure 1, which exemplarily shows a Type-C pin layout, where GND is a ground pin and VBUS is a power bus pin; in common scenarios such as device charging, in addition to the GND pin used to provide grounding and the VBUS pin used to provide power, it usually involves data transmission differential pins D+ (data positive pin) and D- (data negative pin) for charging negotiation between devices, and the configuration channel pin CC used to determine the power role (i.e., power provider and power receiver) and data role (i.e., data provider and data receiver) between devices. They are the core pins for realizing device charging and data transmission. In the Type-C form factor standard, two CC pins (i.e., CC1 pin and CC2 pin) are specified, but in actual applications, generally only one CC pin (i.e., one CC channel) is sufficient to complete the above functions. Therefore, in common application scenarios, one CC pin is usually reserved as a spare pin (i.e., the pin is actually in a disabled state), and only the other CC pin specified by Type-C is used to implement the configuration channel pin function.

[0051] In addition, the TX (Transmit) and RX (Receive) pins are also frequently used in some scenarios. The TX pin is used to send data, while the RX pin is used to receive data. These two pins are often used in scenarios such as serial communication, such as UART (Universal Asynchronous Receiver / Transmitter) communication. As for the SBU (Sideband Use) pin, the frequency of use is relatively low. The SBU pin is mainly used to support some special functions, such as wired video output functions such as DisplayPort, and to transmit audio signals in it.

[0052] Next, the embodiments of the present disclosure are described in detail.

[0053] The first aspect of the present disclosure provides an interface, which can be mounted on a terminal device such as a mobile phone or a tablet computer, and includes a plurality of interface pins. At least two of the plurality of interface pins are used to connect to a first interface channel of a device circuit, and the first interface channel is used to transmit a target signal; the at least two interface pins are used to connect to at least two connector pins of a connector in a one-to-one correspondence; wherein, when the interface is connected to the outside, one of the at least two interface pins is used to transmit the target signal to the first interface channel.

[0054] The at least two connector pins are used to connect to a first connection channel among multiple connector channels of a connection line, and the first connection channel is used to transmit a target signal. When the connector is connected to an interface, one connector pin of the at least two connector pins is used to transmit the target signal based on the first connection channel.

[0055] See also Figure 2 , which exemplarily shows an interface and a connector (which does not necessarily show all the pins of the interface and the connector). The at least two interface pins include a CC1 pin, a CC2 pin, an SBU1 pin, and an SBU2 pin, which are connected in parallel to the CC1 channel of the device circuit. In this example, the target signal is a configuration channel signal, for example, based on a high level or low level signal, determining the data role and power role between the device circuit and the device corresponding to the connector (i.e., the device to which the other end of the connector is connected); in addition, the target signal can also be a protocol data signal (such as device protocol handshake data) and other signals, which are not limited in the present disclosure.

[0056] In the present disclosure, the device circuit is a concept relative to the interface pins. The interface pins are usually mounted on the device or connected to the device through other media. The mainboard, chip and other components of the device usually have interface channels corresponding to the interface pins. These interface channels usually correspond to the interface pins one by one and are used to provide the mainboard, chip and other device circuits with connections corresponding to the interface pins. It is worth noting that in the present disclosure, the interface channel is a logical concept relative to the interface pins. In actual applications, it can be a conductor between the device circuit and the pin contact (i.e., the part of the interface used to directly contact the connector contact), or a specially designed circuit in the device circuit, which is not limited in the present disclosure. Since the device circuit is usually configured to support the standard of the interface, the device circuit is usually designed with interface channels corresponding one to one to the interface pins, that is, the device circuit includes at least two interface channels corresponding one to one to the at least two interface pins; optionally, the interface channels other than the first interface channel among the at least two interface channels are configured to be in an open circuit state, so that the device circuit recognizes that among the at least two interface channels, the interface channels other than the first interface channel are in a disabled state, thereby preventing the device circuit from sending or receiving signals based on these interfaces, thereby avoiding disorder of the interface functions.

[0057] Next, the pins that the at least two interface pins may include are introduced. Taking the Type-C interface as an example, as mentioned above, in actual applications, since the device circuit usually only needs one CC pin to realize the identification of the data role and the power supply role, the at least two interface pins may include a CC1 pin (a second configuration channel pin) and a CC2 pin (a second configuration channel pin), so as to achieve the technical effect of ensuring that the target signal can still be transmitted between the device circuit and the first connection channel when a part of the at least two interface pins is damaged without affecting the original function of the interface. In addition, in some cases, the D+ pin and the D- pin will also participate in the identification of the data role and the power supply role, so the at least two interface pins may include a D+ pin and a D- pin. That is, the at least two interface pins may include at least two of the CC1, CC2, D+, and D- pins.

[0058] Furthermore, since the SBU pin is extremely uncommon (especially for mobile devices such as mobile phones), the at least two interface pins may include a first side band pin SBU1 and a second side band pin SBU2, thereby achieving the above-mentioned technical effects and taking into account both the functionality and reliability of the interface while adapting to common application scenarios of the device.

[0059] Furthermore, the at least two interface pins may include a first transmitting negative electrode pin TX1-, a first receiving negative electrode pin RX1-, a second transmitting negative electrode pin TX2-, and a second receiving negative electrode pin RX2-. This is because the four pins are physically adjacent to the VBUS pin used for power supply, and due to the humidity of the use environment, contamination of the interface, poor performance of the insulator, etc., the probability of corrosion damage is usually greater than that of other pins that are relatively far away from the VBUS pin, thereby further enhancing the reliability of the interface.

[0060] Finally, the at least two interface pins may include a first transmitting positive pin TX1+, a first receiving positive pin RX1+, a second transmitting positive pin TX2+, and a second receiving positive pin RX2+, thereby maximizing reliability without affecting the basic data transmission function of the charging function of the interface.

[0061] In summary, in the embodiments of the present disclosure, the interface circuit includes a plurality of interface pins, at least two of the plurality of interface pins are connected to the first interface channel of the device circuit, and the first interface channel is used to transmit the target signal; the at least two interface pins are used to be connected to at least two connector pins of the connector in a one-to-one correspondence, and the at least two connector pins are connected to the first connection channel among the plurality of connection channels of the connection line, and the first connection channel is used to transmit the target signal. Based on this, when the connector is connected to the interface, the device circuit will have a plurality of signal paths that can be connected to the first connection channel of the connection line and can be used to transmit the target signal, thereby exponentially reducing the possibility of an unavailable phenomenon occurring between the device circuit and the first connection channel (for example, the unavailable probability of each pin is c, and the at least two interface pins include N interface pins, then the probability of an unavailable phenomenon occurring between the device circuit and the first connection channel in this solution is c N , where 0 < c < 1 and N is a positive integer), ensuring the availability of the interface and the connector; in addition, compared with the solution of electroplating anti-corrosion materials such as rhodium ruthenium and platinum on the interface or connector pins, the cost of this solution is extremely low (almost negligible). At the same time, it is ensured that when a part of the pins among the at least two interface pins are damaged, the target signal can still be transmitted between the device circuit and the first connection channel, providing a guarantee for signal transmission after the interface and the connector are corroded, and greatly improving the availability of the interface and the connector.

[0062] In some embodiments of the present disclosure, the interface further includes a multiplexer. For example, the multiplexer can be disposed between the at least two interface pins and the first interface channel. Among them, the multiplexer has multiple states, and the multiplexer is used to connect different sets of interface pins to the first interface channel in different states, and the set of interface pins includes at least one interface pin.

[0063] Please refer to Figure 3 , there may be a switch for controlling signal on / off between the at least two interface pins and the first interface channel. Based on this, the device circuit can control the on / off of the first interface channel and each interface pin among the at least two interface pins to try one by one whether it is feasible to transmit the target signal based on each pin. For example, if the first interface channel is the channel corresponding to the CC1 pin, the device circuit can give priority to transmitting the target signal based on CC1, and when the transmission fails, then try to transmit the target signal based on CC2, and so on.

[0064] In the above scheme, firstly, when there are available pins among at least two interface pins, the device circuit can transmit signals only based on one or some of the available pins, thereby avoiding applying voltage to other unused pins, and then avoiding accelerating the corrosion rate of other pins without affecting the technical effect, and avoiding the danger of the already corroded and damaged pins, further increasing the life of the interface and improving the safety of the interface; in addition, since the connection between the first interface channel and at least two interface pins is optional, the above scheme can be compatible with any original function of the interface; for example, when the device circuit determines through a pre-performed handshake that the interface and the connector will transmit video data through the Display Port protocol, the connection between SBU1 and SBU2 and the CC1 channel can be kept in an open state at all times (that is, in this transmission, the target signal is not transmitted based on the SBU1 and SBU2 pins), so that SBU1 and SBU2 can be used to transmit audio in the Display Port protocol without being interfered by the signal transmitted on the CC1 channel, maximizing the functionality and reliability of the interface.

[0065] The second aspect of the present disclosure provides a connector, which can be used to cooperate with the interface provided in the first aspect to achieve data transmission or power supply. The connector includes a plurality of connector pins, at least two of which are used to connect to a first connection channel among a plurality of connector channels of a connection line, and the first connection channel is used to transmit a target signal; the at least two connector pins are used to be connected to at least two interface pins of an interface of a device in a one-to-one correspondence; wherein, when the connector is connected to the interface, one of the at least two connector pins is used to transmit the target signal based on the first connection channel.

[0066] The at least two interface pins are connected to a first interface channel of a device circuit, and the first interface channel is used to transmit the target signal. When the interface is connected to the outside, one of the at least two interface pins is used to transmit the target signal to the first interface channel.

[0067] Optionally, the connector includes a Universal Serial Bus (USB) connector, and the plurality of connector pins include at least two of CC1, CC2, D+ and D-.

[0068] Similar to the aforementioned embodiment, in the present disclosure, the connecting line is also a logical concept. In wired data transmission, the connecting line can be a physical cable (with other connectors or device circuits connected to the other end). When the connector is directly mounted on the device, the connecting line can be the same concept as the aforementioned device circuit. Due to the aforementioned reasons, the connecting line can have only one first connection channel for transmitting the target signal, thereby saving costs. For specific details and technical effects of the second aspect embodiment, please refer to the relevant parts of the first aspect embodiment, which will not be repeated here.

[0069] In the disclosed embodiment, the interface circuit includes a plurality of interface pins, at least two of the plurality of interface pins are connected to a first interface channel of the device circuit, and the first interface channel is used to transmit a target signal; the at least two interface pins are used to be connected to at least two connector pins of the connector in a one-to-one correspondence, and the at least two connector pins are connected to a first connection channel of a plurality of connection channels of the connecting line, and the first connection channel is used to transmit the target signal. Based on this, when the connector is connected to the interface, the device circuit will have a plurality of signal paths that can be connected to the first connection channel of the connecting line and can be used to transmit the target signal, thereby exponentially reducing the possibility of unavailability between the device circuit and the first connection channel, ensuring the availability of the interface and the connector; in addition, compared with the solution of electroplating anti-corrosion materials such as rhodium ruthenium and platinum on the interface or connector pins, the cost of this solution is extremely low, and at the same time, it ensures that when a portion of the at least two interface pins are damaged, the target signal can still be transmitted between the device circuit and the first connection channel, which guarantees the signal transmission after the interface and connector are corroded, and greatly improves the availability of the interface and the connector.

[0070] In a third aspect, the present disclosure provides a cable, comprising a connecting wire and at least one connector as described in the second aspect.

[0071] Specifically, the cable may have multiple ends, each end corresponds to a connector or a device circuit, each end is connected by a connecting line, and at least one of the multiple ends is connected to the connector as described in the second aspect.

[0072] See also Figure 4 , taking the cable comprising two ends as an example, when both ends are connected to the connector as described in the second aspect (ie Figure 4 The example shown in part a of the embodiment of the first aspect or the embodiment of the second aspect can reuse the technical solution described in the embodiment of the first aspect or the embodiment of the second aspect to obtain the technical solution of the third aspect. The following describes a case where one end is connected to the connector as described in the second aspect and the other end is connected to a first connector different from the connector described in the second aspect.

[0073] The cable includes multiple connectors, at least one connector among the multiple connectors is the connector as described in the embodiment of the second aspect, any specific pin of other connectors among the multiple connectors except the connector described in the embodiment of the second aspect is connected to the first connection channel, and the other connectors have one or more specific pins, and the specific pins are used to transmit the target signal.

[0074] Apart from Figure 4 In addition to the unmodified conventional Type-C connector shown in part b of FIG. 1 (ie, having CC1 pin and CC2 pin), the first connector may also be Figure 4 The interface appearance standards specified by other protocols shown in part c (such as Lightning with a CC pin), or customized private interface appearance standards; for example, the traditional USB Type-A and USB Type-B interface appearance standards have only four pins (excluding the CC pin), but in order to achieve compatibility with the Type-C protocol, or to achieve richer interface functions, in actual applications, manufacturers usually add an additional CC pin to interfaces such as USB Type-A and USB Type-B for transmitting the target signal. For the above-mentioned connector containing only one CC pin, the first connection channel can be connected to the CC pin. For connectors with multiple CC pins such as conventional Type-C connectors, the first connection channel can be connected to any one of the multiple CC pins, and the other pins can remain in an open state, so that the device can normally transmit the target signal based on the first connection channel and realize the corresponding function, avoiding the disorder of the interface function. At the same time, the device connected to the first connector does not need to make circuit changes to be compatible with the solution provided by the present disclosure, thereby improving the universality of the cable disclosed in the present disclosure. It should be understood that when a cable includes different types of connectors, in order to make it easier for users to distinguish between different connectors, different appearance designs or text marks can be used to distinguish between different types of connectors.

[0075] For specific details and technical effects of the third aspect embodiment, please refer to the relevant parts of the first and second aspects embodiments, which will not be repeated here.
