Description

Technical Field

[0001] The utility model relates to the technical field of Type-C connectors, and particularly relates to a connector for Type-C multi-channel selection. Background Art

[0002] Although the existing 24Pin Type-C female socket and male head can provide multi-channel data transmission, the circuit board assembled with 24 Pins requires at least a four-layer board, and the soldering process is relatively complex, and it is easy to have poor phenomena such as virtual soldering and continuous soldering. Troubleshooting, maintenance or replacement of the circuit board later are all very time-consuming and inefficient tasks, and the price of the 24Pin Type-C female socket is also relatively expensive.

[0003] Therefore, most electronic products using Type-C power supply or communication adopt 16Pin Type-C female sockets. However, in the 16Pin Type-C female socket, in addition to the VBUS pin, GND pin, DP1 pin and DN1 pin for data communication with the common channel, and the CC1 and CC2 pins for power communication protocol transmission, only the four pins of DP2, DN2, SBU1, and SBU2 can be connected to the data line as the interface for program loading, upgrading, maintenance, reading and writing storage data, etc. of the control system of the electronic product. If separate operations need to be performed on multiple control systems within the same product, the housing has to be opened and operated separately. Disassembly, assembly and maintenance are time-consuming, resulting in low work efficiency. Moreover, repeated plugging and unplugging of the interface easily causes damage to the interface, and then leads to failures due to poor contact of the plug-in components; or an additional socket is assembled, and the program loading, upgrading, maintenance, reading and writing storage data, debugging of each interface or IO port are independently led out to a single or multiple sockets, which will increase the complexity of the product housing and the cost is relatively high. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a connector for Type-C multi-channel selection, which can realize separate operations on multiple control systems within an electronic product. The number of female socket pins is small, the number of communication lines is reduced, the reliability of the circuit can be enhanced, and there is no need to additionally set a socket, so the cost is low; only by switching the switch state of the switch group can the data transmission channel be switched, the operation is simple and fast, the work efficiency is high, the interface is not easily damaged, and the failure rate is low.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0025] As Figure 1 shown, the connector for Type-C multi-channel selection in the embodiment of the present utility model includes a male head component 10 and a female socket component 20 connected by plugging and unplugging. The male head component 10 includes a Type-C male head 11 and a switching switch group 12. The Type-C male head 11 includes a first data transmission pin 111 and a first channel selection pin 112. The first data transmission pin 111 is used to connect to an external data source, and the first channel selection pin 112 is connected to the switching switch group 12. Among them, the switching switch group 12 has N switch states, and N is an integer greater than 1 and less than or equal to 8; the female socket component 20 includes a 16Pin Type-C female socket 21 and a multi-channel selection module 22. The 16Pin Type-C female socket 21 includes a second data transmission pin 211 and a second channel selection pin 212. The 16Pin Type-C female socket 21 is used to plug into the Type-C male head 11. When the Type-C male head 11 is inserted into the 16Pin Type-C female socket 21 from the front, the second data transmission pin 211 and the second channel selection pin 212 are respectively connected to the first data transmission pin 111 and the first channel selection pin 112. The multi-channel selection module 22 includes a third channel selection pin 221, a first channel connection pin 222, and at least N groups of second channel connection pins 223. The third channel selection pin 221 is connected to the second channel selection pin 212, and the first channel connection pin 222 is connected to the second data transmission pin 211. The first channel connection pin 222 selectively forms a data transmission channel with any one of the second channel connection pins 223. When the switching switch group 12 is switched to the i-th switch state, the first channel connection pin 222 and the i-th group of second channel connection pins 223 form a data transmission channel, so that the data of the external data source is transmitted through this data transmission channel, where i is an integer greater than or equal to 0 and less than or equal to N-1.

[0026] It can be understood that since the multi-channel selection module 22 can, according to the switch states of the switch group 12, enable the data of the external data source to be transmitted through different data transmission channels, so as to realize the independent operation of multiple control systems in the electronic product provided with the female seat component 20 of this connector (such as downloading code, upgrading, communication, debugging, testing, etc.). The female seat of the female seat component 20 is a 16Pin Type-C female seat 21. Compared with the 24Pin Type-C female seat, the 16Pin Type-C female seat 21 has fewer pin numbers, reduces the number of communication lines, can reduce costs, and enhance the reliability of the lines; when switching the data transmission channel, there is no need to open the product shell, nor to plug and unplug the male head component 10. Only by switching the switch states of the switch group 12 can the data transmission channel be switched. The operation is simple and fast, the work efficiency is relatively high, the interface is not easily damaged, and there will be no fault of poor contact of the connector due to multiple plugging and unplugging; there is no need to set an additional socket, and the cost is relatively low.

[0027] As Figure 2 and Figure 3 shown, in an embodiment of the present invention, the second data transmission pins 211 may also include two data pins of the 16Pin Type-C female seat 21 (for example, DN1 and DP1). Correspondingly, the first data transmission pins 111 may include the data pins DN1 and DP1 of the Type-C male head 11 for connecting to an external data source; the first channel connection pins 222 may include two data pins (AX and AY) of the multi-channel selection module 22, and the i-th group of second channel connection pins 223 may include two data pins (AiX, AiY) for forming a data transmission channel.

[0028] It can be understood that the second data transmission pins 211 may also be the data pins DN2 and DP2 of the 16Pin Type-C female seat 21, and the Type-C male head 11 may correspondingly set the first data transmission pins 111. This embodiment is not limited thereto.

[0029] In an embodiment of the present invention, the switch group 12 includes M independently controllable switches, each switch is correspondingly connected to a first channel selection pin 112, and each switch has a first control state and a second control state, so that the switch group 12 has at most 2 M kinds of switch states, where M is equal to 2 or 3. Correspondingly, the first channel selection pins 112, the second channel selection pins 212, and the third channel selection pins 221 may all be M. When the Type-C male head 11 is inserted into the 16Pin Type-C female seat 21, the control state of each switch can affect the signal received by the multi-channel selection module 22, and further enable the first channel connection pins 222 of the multi-channel selection module 22 and a group of second channel connection pins 223 to form a data transmission channel.

[0030] When M is equal to 2, the switching switch group 12 has at most 4 switch states, and at most four data transmission channels in the multi-channel selection module 22 are available for selection; when M is equal to 3, the switching switch group 12 has at most 8 switch states, and at most eight data transmission channels in the multi-channel selection module 22 are available for selection.

[0031] Specifically, two or three of the other data pins (DN2, DP2, SBU1, SBU2) of the 16Pin Type-C female socket 21 can be used as the second channel selection pins 212. The first channel selection pin 112 in the Type-C male head 11 can correspond to the 16Pin Type-C female socket 21, and the third channel selection pin 221 in the multi-channel selection module 22 can correspond to the 16Pin Type-C female socket 21.

[0032] As shown in FIG. 2, in an embodiment of the present invention, the multi-channel selection module 22 may include a multi-channel selection chip U1 and a first pull-up resistor. The multi-channel selection chip U1 has a third channel selection pin 221, a first channel connection pin 222, and at least N groups of second channel connection pins 223. The signal connection end of the first pull-up resistor is connected between the connection line of the third channel selection pin 221 and the second channel selection pin 212. In the figure, R1, R2, and R3 may be the first pull-up resistors, SEL0, SEL1, and SEL2 may be the third channel selection pins, A0X, A0Y, A1X, A1Y, A2X, A2Y, A3X, A3Y, A4X, A4Y, A5X, A5Y, A6X, A6Y, A7X, and A7Y are the second channel connection pins, and DN2, DP2, and SBU1 may be the second channel selection pins.

[0033] When the Type-C male head 11 is inserted into the 16Pin Type-C female socket 21 face-up and the j-th switch is in the first control state, the signal connection end of the first pull-up resistor corresponding to the switch is in a high level state, and the level signal generated by the third channel selection pin connected to the signal connection end of the first pull-up resistor is a high level; when the j-th switch is in the second control state, the signal connection end of the first pull-up resistor corresponding to the switch is in a low level state, and the third channel selection pin connected to the signal connection end of the first pull-up resistor generates a low level signal, so that each switch state of the switching switch group 12 corresponds to a set of level signals of a third channel selection pin 221. The multi-channel selection chip U1 controls the first channel connection pin 222 and a group of second channel connection pins 223 to form a data transmission channel corresponding to the set, where j is an integer greater than or equal to 1 and less than or equal to M.

[0034] Set the high-level signal as 1 and the low-level signal as 0. When M equals 2, the multi-channel selection chip U1 can control the first-channel connection pin 222 and the second-channel connection pin 223 to form a data transmission channel according to Table 1 below.

[0035] Table 1

[0036]

[0037] In the table, SEL1 and SEL0 respectively represent the two third-channel selection pins of the multi-channel selection chip U1. When both switches of the switch group 12 are in the first control state, the switch group 12 is in the 3rd switch state, and the set of level signals generated by SEL0 and SEL1 is (1, 1). At this time, when the first-channel connection pin AX selects the second-channel connection pin A3X and the first-channel connection pin AY selects the second-channel connection pin A3Y, a data transmission channel is formed. Similarly, the composition method of the data transmission channel in other switch states of the switch group 12 can be obtained.

[0038] When M equals 3, the multi-channel selection chip can control the first-channel connection pin 222 and the second-channel connection pin 223 to form a data transmission channel according to Table 2 below.

[0039] Table 2

[0040]

[0041] In the table, SEL2, SEL1, and SEL0 respectively represent the three third-channel selection pins of the multi-channel selection chip. When all three switches of the switch group are in the first control state, the switch group 12 is in the 7th switch state, and the set of level signals generated by SEL2, SEL1, and SEL0 is (1, 1, 1). At this time, when the first-channel connection pin AX selects the second-channel connection pin A7X and the first-channel connection pin AY selects the second-channel connection pin A7Y, a data transmission channel is formed. Similarly, the composition method of the data transmission channel in other switch states of the switch group can be obtained.

[0042] In an embodiment of the present invention, in order to achieve up to eight channels selectable, the multi-channel selection chip can be a differential pair octal selector (DPOT) analog switch chip, such as CH448F. In some other embodiments of the present invention, other multi-channel analog switch chips can also be used as the multi-channel selection chip according to the actual product requirements, such as a differential pair quadruple selector (DPQT) analog switch chip, etc., and the present invention is not limited thereto.

[0043] In the present utility model, in the Type-C male connector 11, for one set of the two sets of pins with data transmission functions, namely DN1 and DP1, and DN2 and DP2, one set will serve as the first data transmission pins 111, and at least one pin in the other set needs to serve as the first channel selection pins 112. Once the Type-C male connector 11 is not inserted into the 16-pin Type-C female connector 21 correctly, that is, the first data transmission pins 111 are not correspondingly connected to the second data transmission pins 211, the data of the external data source cannot be transmitted through the second data transmission pins 211 from the expected data transmission channel, resulting in data transmission failure.

[0044] As Figure 2 and Figure 3 shown, in an embodiment of the present utility model, to ensure the correct insertion direction of the Type-C male connector 11, the male connector assembly 10 may further include an indicator light D1, the Type-C male connector 11 may further include a first insertion direction identification pin SBU2, the first insertion direction identification pin SBU2 is connected to the indicator light D1, the 16-pin Type-C female connector 21 may further include a second insertion direction identification pin SBU2 and a second pull-up resistor R4, the second insertion direction identification pin SBU2 is connected to the signal connection end of the second pull-up resistor R4. When the Type-C male connector 11 is inserted into the 16-pin Type-C female connector 21 correctly, the second insertion direction identification pin SBU2 of the 16-pin Type-C female connector 21 is connected to the first insertion direction identification pin SBU2 of the Type-C male connector 11, the signal connection end of the second pull-up resistor R4 is in a high-level state, and the indicator light D1 obtains power supply from the second pull-up resistor R4.

[0045] In an embodiment of the utility model, the resistance value of the second pull-up resistor R4 is less than that of the first pull-up resistor.

[0046] It can be understood that in the present utility model, since the first insertion direction identification pin SBU2 of the Type-C male head 11 is connected to the indicator light D1, and the SBU1 pin of the 16Pin Type-C female socket 21 is connected to the signal connection end of the first pull-up resistor R1, if the Type-C male head 11 is not inserted into the 16Pin Type-C female socket 21 correctly, it will cause the SBU1 pin of the 16Pin Type-C female socket 21 to be connected to the first insertion direction identification pin SBU2 of the Type-C male head 11, resulting in the signal connection end of the first pull-up resistor R1 being in a high-level state, and the indicator light D1 obtaining power supply from the first pull-up resistor R1. Since the resistance value of the second pull-up resistor R4 is less than that of the first pull-up resistor, when the insertion direction of the Type-C male head 11 is correct, the working brightness of the indicator light D1 is brighter, and when the insertion direction of the Type-C male head 11 is incorrect, the working brightness of the indicator light D1 is dimmer. The operator can judge the insertion direction of the Type-C male head 11 according to the working condition of the indicator light to ensure that data is transmitted through the selected data transmission channel.

[0047] Specifically, the resistance of the second pull-up resistor R4 can be set to at least one-tenth of that of the first pull-up resistor R1, so that there is an obvious difference in the brightness of the indicator light D1.

[0048] As Figure 4 shown, in a specific embodiment of the present utility model, a group of pins (A7X, A7Y) in the second channel connection pins of the multi-channel selection chip U1 can be used as the interface of the default data transmission channel and connected to the data terminal 30 of the electronic product, and other pins in the second channel connection pins of the multi-channel selection chip U1 can be used as the interfaces of the data transmission channels 40 of other independent control systems in the electronic product.

[0049] When the male head inserted into the 16Pin Type-C female socket 21 is not the Type-C male head 11 in this embodiment but a general Type-C male head, since the second channel selection pin 212 of the 16Pin Type-C female socket 21 is in a floating state, the signal connection ends of the first pull-up resistors are all in a high-level state, making the data transmission channel in the multi-channel selection chip U1 the default data transmission channel, that is, the data transmission channel at this time is composed of the first channel connection pin 222 and (A7X, A7Y), and data can be transmitted through the multi-channel selection chip U1 and the data terminal 30 without affecting the normal use of the female socket assembly 20.

[0050] In an embodiment of the present utility model, the male head assembly 10 may further include a Type-C female socket for connecting to an external power source. The CC1, CC2, VBUS, and GND pins of the Type-C female socket may be connected to the CC1, CC2, VBUS, and GND pins of the Type-C male head 11, so that when the Type-C male head 11 is inserted into the 16Pin Type-C female socket 21, the external power source can supply power to the electronic product through the Type-C female socket, the Type-C male head 11, and the 16Pin Type-C female socket 21. Since the pins (CC1, CC2, VBUS pins) for providing power and power management do not participate in the data transmission of the external data source, regardless of whether the insertion direction of the Type-C male head 11 is correct, the external power source can stably supply power to the electronic product without affecting the original power supply method and protocol.

[0051] For the connector for Type-C multi-channel selection according to the embodiment of the present utility model, by providing a switching switch group connected to the Type-C male head in the male head assembly and a multi-channel selection module connected to the 16Pin Type-C female socket in the female head assembly, the multi-channel selection module can, according to the switch state of the switching switch group, enable the data of the external data source to be transmitted through different data transmission channels, thereby realizing the independent operation of multiple control systems in the electronic product provided with the female head assembly of the connector; the female head assembly uses a 16Pin Type-C female socket, with fewer pin numbers, reducing the number of communication lines, lowering the complexity of the soldering process, reducing the failure rate, and improving the product yield rate; when switching the data transmission channel, there is no need to open the product shell, nor to plug and unplug the male head assembly. Only by switching the switch state of the switching switch group can the data transmission channel be switched. The operation is simple and fast, with high work efficiency, the interface is not easily damaged, and the failure rate is low; there is no need to set up an additional socket, and the cost is low.
