Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0046] In the related art, in the method of welding quality detection for the horizontal Type-C female terminal 1 wiring board based on functional actual measurement, during the functional actual measurement process, it is necessary to frequently turn on and off the power and enter the system. It takes about 3 minutes to detect a horizontal Type-C female terminal 1 wiring board. If 10,000 PCS of Type-C female terminal 1 wiring boards need to be tested, it will take about 500 hours, resulting in a long time-consuming for the welding quality detection of Type-C female terminal 1.

[0047] In view of this, in an embodiment of the present invention, a Type-C female terminal detection device is provided. The Type-C female terminal detection device is applicable to detect the open soldering and / or bridging of the Type-C female terminal 1; wherein, the signal pins of the Type-C female terminal 1 are composed of a ground pin and functional pins, and the functional pins include a bus power pin and other pins.

[0048] See Figure 1 , Figure 1 is a structural block diagram of a Type-C female terminal detection device according to an embodiment of the present invention.

[0049] As Figure 1As shown in the figure, the Type-C female end detection device provided in the embodiment of the present invention includes an open solder detection component 2, a solder bridging detection component 3, a first connector 4, and a second connector 5. Among them, the open solder detection component 2 includes a plurality of first light-emitting components KD1. The first light-emitting components KD1 correspond to signal pins, and the positive poles of the first light-emitting components KD1 are connected to the positive pole of the power supply; the solder bridging detection component 3 includes a plurality of second light-emitting components KD2. The second light-emitting components KD2 correspond to function pins, and the second light-emitting components KD2 corresponding to any two adjacent function pins are respectively connected to the positive pole and the negative pole of the power supply; among them, when two adjacent function pins are soldered together, the two soldered function pins, the corresponding second light-emitting component KD2, and the power supply form a loop; the first connector 4, its first end is used to connect to the female port of the Type-C female end, and its second end is connected to the negative pole of the first light-emitting component KD1 and the end of the second light-emitting component KD2 away from the power supply. The first connector 4 is used to connect each first light-emitting component KD1 to the corresponding signal pin during open solder detection, and is used to connect each second light-emitting component KD2 to the corresponding function pin during solder bridging detection; the second connector, its first end is used to connect to the male port of the Type-C female end, and its second end is connected to the negative pole of the power supply. The second connector is used to connect the male port of the Type-C female end to the negative pole of the power supply during open solder detection.

[0050] In the Type-C female end detection device provided in this embodiment, since the positive poles of the first light-emitting components KD1 of the open solder detection component 2 are connected to the positive pole of the power supply, the negative poles of the first light-emitting components KD1 are connected to the second end of the first connector 4, and the negative pole of the power supply is connected to the second end of the second connector. Therefore, when performing open solder detection on the Type-C female end, only need to connect the first end of the first connector 4 to the female port of the Type-C female end, and connect the first end of the second connector to the male port of the Type-C female end, then a loop can be formed between the power supply, the first light-emitting component KD1, and the corresponding signal pin, so as to judge whether there is an open solder on the signal pins of the Type-C according to the light-emitting state of the first light-emitting component KD1. In addition, in the solder bridging detection component 3, the second light-emitting components KD2 corresponding to any two adjacent function pins are respectively connected to the positive pole and the negative pole of the power supply. Therefore, when performing solder bridging detection on the Type-C female end, only need to connect the first end of the first connector 4 to the female port of the Type-C female end, then when any two adjacent function pins are soldered together, a loop can be formed between the two adjacent function pins where the solder bridging occurs, the second light-emitting component KD2 corresponding to the soldered function pin, and the power supply, so as to judge whether there is a solder bridging on the signal pins / function pins of the Type-C according to the light-emitting state of the second light-emitting component KD2. The implementation method of the Type-C female end detection device of the present invention for detecting the welding quality of the Type-C female end detection device is simple and less time-consuming.

[0051] Specifically, when performing an open solder detection on the female Type-C terminal, connect the first end of the first connector 4 to the female port of the female Type-C terminal, and connect the first end of the second connector to the male port of the female Type-C terminal; if any of the first light-emitting components KD1 does not emit light, it is determined that there is an open solder on the female Type-C terminal; if all the first light-emitting components KD1 emit light, it is determined that there is no open solder on the female Type-C terminal.

[0052] It can be understood that when there is an open solder on any signal pin, the negative electrode of the first light-emitting component KD1 corresponding to the open-soldered signal pin is disconnected from the negative electrode of the power supply, and the open-soldered signal pin, the corresponding first light-emitting component KD1 and the power supply cannot form a loop, so the first light-emitting component KD1 corresponding to the open-soldered signal pin does not emit light. Therefore, the presence or absence of an open solder on the signal pins of the female Type-C terminal and the specific signal pins with open solder can be judged according to the light-emitting state of the first light-emitting component KD1.

[0053] Specifically, when performing a solder bridge detection on the female Type-C terminal, connect the first end of the first connector 4 to the female port of the female Type-C terminal; if any of the second light-emitting components KD2 corresponding to other pins emits light, it is determined that there is a solder bridge on the female Type-C terminal; if all the second light-emitting components KD2 corresponding to other pins do not emit light, it is determined that there is no solder bridge on the female Type-C terminal.

[0054] It can be understood that when there is a solder bridge between any two adjacent functional pins, the two functional pins with the solder bridge, the corresponding second light-emitting component KD2 and the power supply will form a loop, so the second light-emitting component KD2 corresponding to the two functional pins with the solder bridge emits light. When there is no solder bridge between two adjacent functional pins, the two functional pins are disconnected, so the two functional pins, the corresponding second light-emitting component KD2 and the power supply cannot form a loop, and the second light-emitting component KD2 corresponding to other pins in the non-soldered functional pins does not emit light. It should be noted that since the bus power pins in the functional pins of the female Type-C terminal are interconnected, when judging whether there is a solder bridge between adjacent functional pins, it is mainly judged whether there is a solder bridge on the signal pins / functional pins of the female Type-C terminal and the specific signal pins / functional pins with the solder bridge according to the light-emitting state of the second light-emitting component KD2 corresponding to other pins in the functional pins.

[0055] It should be noted that in actual operation, the first end of the first connector 4 can be separately connected to the female port of the Type-C female end to perform tin bridging detection on the Type-C female end alone. Or, the first end of the first connector 4 is connected to the female port of the Type-C female end, and the first end of the second connector is connected to the male port of the Type-C female end to perform open solder detection and tin bridging detection on the Type-C female end simultaneously. Or, a switch device SW is provided on the positive or negative side of the power supply connected to the second light-emitting component KD2. When the first end of the first connector 4 is connected to the female port of the Type-C female end and the first end of the second connector is connected to the male port of the Type-C female end, the switch device SW is used to control the on / off of the second light-emitting component KD2 and the power supply to control the start or stop of the tin bridging detection, so as to perform open solder detection on the Type-C female end alone, or perform open solder detection and tin bridging detection on the Type-C female end simultaneously.

[0056] It can be understood that the Type-C female end detection device provided by the embodiment of the present invention only needs to be connected to the Type-C female end 1 through the first connector 4 and the second connector 5, and the welding quality of the connector of the Type-C female end 1 can be detected according to the light-emitting states of the first light-emitting component KD1 and the second light-emitting component KD2, and there is no need to frequently turn on and off the machine and enter the system like the functional actual measurement detection method. Therefore, compared with the functional actual measurement detection method, the detection time can be greatly shortened. After testing, it takes about 3s to detect the welding quality of a Type-C female end 1 by using the Type-C female end detection device provided by the embodiment of the present invention. Compared with the functional actual measurement detection method, the detection efficiency is increased by nearly 60 times.

[0057] As an optional implementation manner, the functional pins of the Type-C female end include a bus power pin and other pins; among them, the second light-emitting component KD2 corresponding to the bus power pin has a different light-emitting form from the second light-emitting component KD2 corresponding to the other pins.

[0058] Optionally, the light-emitting form is the light-emitting color. In addition, the light-emitting form can be adjusted to other light-emitting forms such as the light-emitting frequency according to the actual situation.

[0059] Specifically, the first light-emitting component KD1 and the second light-emitting component KD2 are light-emitting diodes.

[0060] Further, if the light-emitting form is the light-emitting color, the first light-emitting component KD1 is used to emit light of a first color, the second light-emitting component KD2 corresponding to the other pins is used to emit light of a second color, and the second light-emitting component KD2 corresponding to the bus power pin is used to emit light of a third color; among them, the second color and the third color are different.

[0061] Exemplarily, taking the first color as green, the second color as red, and the third color as green as an example, the first light-emitting component KD1 emits green light when turned on, the second light-emitting component KD2 corresponding to other pins emits red light when turned on, and the second light-emitting component KD2 corresponding to the bus power pin emits green light when turned on. In addition, the third color can also be blue or yellow. It should be noted that the first color can be selected to be the same as the second color or the same as the third color, and the selection of the first color is not limited here.

[0062] In addition, if the light-emitting form is the light-emitting frequency, the first light-emitting component KD1 is used to emit light of the first frequency, the second light-emitting component KD2 corresponding to other pins is used to emit light of the second frequency, and the second light-emitting component KD2 corresponding to the bus power pin is used to emit light of the third frequency; wherein, the second frequency and the third frequency are different.

[0063] Exemplarily, taking the first frequency as always-on, the second frequency as 1 Hz, and the third frequency as always-on as an example, the first light-emitting component KD1 is always-on when turned on, the second light-emitting component KD2 corresponding to other pins blinks at a frequency of 1 Hz when turned on, and the second light-emitting component KD2 corresponding to the bus power pin is always-on when turned on. In addition, the third frequency can also be other frequencies such as 2 Hz. It should be noted that the first frequency can be selected to be the same as the second frequency or the same as the third frequency, and the selection of the first frequency is not limited here.

[0064] As another alternative implementation manner, the light-emitting component shape of the second light-emitting component KD2 corresponding to the bus power pin is different from that of the second light-emitting component KD2 corresponding to other pins.

[0065] Specifically, the first light-emitting component KD1 is a light-emitting component of the first shape, the second light-emitting component KD2 corresponding to other pins is a light-emitting component of the second shape, and the second light-emitting component KD2 corresponding to the bus power pin is a light-emitting component of the third shape; wherein, the second shape and the third shape are different.

[0066] Exemplarily, taking the first shape as a triangle, the second shape as a circle, and the third shape as a triangle as an example, the first light-emitting component KD1 is a triangular light-emitting component, the second light-emitting component KD2 corresponding to other pins is a circular light-emitting component, and the second light-emitting component KD2 corresponding to the bus power pin is a triangular light-emitting component. In addition, the third shape can also be a square or other shapes. It should be noted that the first shape can be selected to be the same as the second shape or the same as the third shape, and the selection of the first shape is not limited here.

[0067] It should be noted that in the Type-C female terminal, the bus power pins are interconnected. Therefore, if the positive electrode of the second light-emitting component corresponding to any bus power pin is connected to the positive electrode of the power supply, when there is no solder bridging on the bus power pin, it may also cause the second light-emitting component KD2 corresponding to the bus power pin to emit light. If the light-emitting form of the second light-emitting component KD2 corresponding to the bus power pin is the same as that of the second light-emitting component KD2 corresponding to other pins, it is easy to mislead relevant personnel when there is no solder bridging on the bus power pin because the second light-emitting component KD2 corresponding to the bus power pin emits light. Therefore, in order to facilitate relevant personnel to better distinguish the situation of no solder bridging and the situation of solder bridging, it is necessary to make the light-emitting forms of the second light-emitting component KD2 corresponding to the bus power pin and the second light-emitting component KD2 corresponding to other pins different.

[0068] Specifically, when performing solder bridging detection on the Type-C female terminal, if any second light-emitting component KD2 corresponding to other pins emits light, it is determined that there is solder bridging on the other pins corresponding to the second light-emitting component KD2; if all the second light-emitting components KD2 corresponding to other pins do not emit light and all the second light-emitting components KD2 corresponding to the bus power pins emit light, it is determined that there is no solder bridging on the Type-C female terminal.

[0069] As an optional implementation manner, a first light-emitting component KD1 is shared among all ground pins, that is, the number of the first light-emitting components KD1 corresponding to the ground pins is one. The number of the first light-emitting components KD1 is the total number of functional pins plus one.

[0070] Exemplarily, taking a double-row Type-C female terminal 1 connector with 24 signal pins and two Type-C female terminal 1 connectors provided on a substrate as an example. On one Type-C female terminal 1 connector, the number of ground pins is 4 and the number of functional pins is 20, then (20 + 1) * 2 = 42 first light-emitting components KD1 are required for open solder detection.

[0071] As an optional implementation manner, the number of the second light-emitting components KD2 is the number of functional pins.

[0072] Exemplarily, take an example where a double-row Type-C female end 1 connector has 24 signal pins and there are two Type-C female end 1 connectors provided on a substrate. A Type-C female end 1 connector has 24 signal pins. In order to detect the solder bridging short circuit phenomenon between adjacent signal pins, 11 second light-emitting components KD2 are required for 12 signal pins in principle. Since the head and the tail of a row of signal pins are both ground pins, a row of signal pins has 2 bus power pins and 8 other pins. Therefore, 8 second light-emitting components KD2 in the first light-emitting form (such as green LED lights) and 2 second light-emitting components KD2 in the second light-emitting form (such as red LED lights) are required for a row of signal pins. For two rows, 16 second light-emitting components KD2 in the first light-emitting form and 4 second light-emitting components KD2 in the second light-emitting form are required. Then, 32 second light-emitting components KD2 in the first light-emitting form and 8 second light-emitting components KD2 in the second light-emitting form are required for two Type-C female end 1 connectors.

[0073] Exemplarily, as Figure 3 shown, take an existing Type-C female end 1 as an example. An existing 24-pin Type-C female end 1 is a set of symmetric connectors. The signal pins in the same row of the Type-C female end 1 are symmetrically arranged left and right and have the same function. The signal pins PIN1, PIN12, PIN13, and PIN24 at both ends of the Type-C female end 1 are ground pins GND. The signal pins PIN4, PIN9, PIN16, and PIN21 are bus power pins VBUS. The remaining signal pins are other pins. Specifically, the signal pins PIN2 and PIN3 are the first group of TX differential pins TX1+ and TX1-. The signal pins PIN22 and PIN23 are the second group of TX differential signals TX2- and TX2+. The signal pin PIN5 is the first channel configuration pin CC1. The signal pins PIN6 and PIN7 are the first group of data pins D+ and D-. The signal pins PIN18 and PIN19 are the second group of data pins D- and D+. The signal pin PIN8 is the first auxiliary communication pin SBU1. The signal pins PIN14 and PIN15 are the first group of RX differential pins RX1+ and RX1-. The signal pins PIN10 and the signal pin PIN11 are the second group of RX differential pins RX2- and RX2+. The signal pin PIN17 is the second auxiliary communication pin SBU2. The signal pin PIN20 is the second channel configuration pin CC2. As Figure 2As shown, in this embodiment, each functional pin is respectively connected to a first light-emitting component KD1, and each ground pin PIN1, PIN12, PIN13, PIN24 is correspondingly connected to the same first light-emitting component KD1. Of course, in actual operation, each ground pin can also be respectively connected to a first light-emitting component KD1, and then the number of the first light-emitting components KD1 is the total number of signal pins of the Type-C female terminal 1.

[0074] As an optional implementation manner, in the order from top to bottom and from left to right, the functional pins of the Type-C female terminal are sorted in sequence. The positive electrode of the second light-emitting component KD2 corresponding to the (2n - 1)-th functional pin is connected to the positive electrode of the power supply, the negative electrode of the second light-emitting component KD2 corresponding to the (2n - 1)-th functional pin is connected to the second end of the first connector 4, where n is a positive integer; the positive electrode of the second light-emitting component KD2 corresponding to the 2n-th functional pin is connected to the second end of the first connector 4, and the negative electrode of the second light-emitting component KD2 corresponding to the 2n-th functional pin is connected to the negative electrode of the power supply.

[0075] As an optional implementation manner, the Type-C female terminal detection device of the embodiment of the present invention further includes a switching device SW; wherein, one end of the switching device SW is connected to the positive electrode of the power supply, and the other end of the switching device SW is connected to the positive electrode of the second light-emitting component KD2 corresponding to the (2n - 1)-th functional pin.

[0076] As another optional implementation manner, one end of the switching device SW is connected to the negative electrode of the power supply, and the other end of the switching device SW is connected to the negative electrode of the second light-emitting component KD2 corresponding to the 2n-th functional pin

[0077] It should be noted that the value of 2n needs to be less than or equal to the total number of signal pins of the Type-C female terminal 1.

[0078] Exemplarily, taking an existing 24-pin Type-C female terminal 1 as an example, the functional pins of the Type-C female terminal 1 are signal pins PIN2 - 11 and signal pins PIN14 - PIN23. Then, the first functional pin in sequence is signal pin PIN2, the second functional pin is signal pin PIN3, and so on, and the 20th functional pin is PIN23. As Figure 4As shown, the first functional pin PIN2, the third functional pin PIN4, the fifth functional pin PIN6, the seventh functional pin PIN8, the ninth functional pin PIN10, the eleventh functional pin PIN14, the thirteenth functional pin PIN16, the fifteenth functional pin PIN18, the seventeenth functional pin PIN20, and the nineteenth functional pin PIN22 are connected to the negative electrodes of the corresponding second light-emitting components KD2, and the positive electrodes of the corresponding second light-emitting components KD2 are connected to the positive electrode of the power supply through the switching device SW. The second functional pin PIN3, the fourth functional pin PIN5, the sixth functional pin PIN7, the eighth functional pin PIN9, the tenth functional pin PIN11, the twelfth functional pin PIN15, the fourteenth functional pin PIN17, the sixteenth functional pin PIN19, the eighteenth functional pin PIN21, and the twentieth functional pin PIN23 are connected to the positive electrodes of the corresponding second light-emitting components KD2, and the negative electrodes of the corresponding second light-emitting components KD2 are connected to the negative electrode of the power supply.

[0079] As an optional implementation manner, the first connector 4 is a Type-C male-female adapter data cable.

[0080] It should be noted that since it is difficult to replace the Type-C data cable after wear, in actual operation, it can be used in combination with a Type-C male-to-female adapter and a Type-C data cable, that is, a Type-C male-female adapter data cable. In the detection, the Type-C male-female adapter data cable is used to connect the Type-C female end 1 to the first light-emitting component KD1 of the open-circuit detection component 2. Specifically, the male port of the Type-C male-female adapter data cable is used as the first end of the first connector 4 and is connected to the female port of the Type-C female end 1. The female port of the Type-C male-female adapter data cable is used as the second end of the first connector 4 and is connected to the negative electrode of the first light-emitting component KD1 and the end of the second light-emitting component KD2 away from the power supply.

[0081] Specifically, the female port of the Type-C female end corresponds to each signal pin of the Type-C female end. When the first end of the first connector 4 is connected to the female port of the Type-C female end, each pin at the second end of the first connector 4 corresponds to each signal pin of the Type-C female end. Further, the Type-C female end detection device further includes a PCB circuit board. Each pin at the second end of the first connector 4 is led out to the PCB circuit board through adhesive tape and wires, obtaining endpoints corresponding to each signal pin of the Type-C female end. Then, using wires and the endpoints corresponding to each signal pin of the Type-C female end, the second end of the first connector 4 is connected to the negative pole of the first light-emitting component KD1 and the end of the second light-emitting component KD2 far from the power supply, so as to connect each first light-emitting component KD1 to the corresponding signal pin during open solder detection, and connect each second light-emitting component KD2 to the corresponding functional pin during solder bridging detection.

[0082] It should be noted that one Type-C female end 1 corresponds to one Type-C male-female transfer data cable. If there are two Type-C female ends 1, two Type-C male-female transfer data cables are required.

[0083] It should be noted that the end of the second light-emitting component KD2 far from the power supply is the end where the second light-emitting component KD2 is not connected to the power supply. Exemplarily, assuming that the positive pole of the second light-emitting component KD2 is connected to the positive pole of the power supply, then the negative pole of the second light-emitting component KD2 is the end of the second light-emitting component KD2 far from the power supply. Assuming that the negative pole of the second light-emitting component KD2 is connected to the negative pole of the power supply, then the positive pole of the second light-emitting component KD2 is the end of the second light-emitting component KD2 far from the power supply.

[0084] As an optional implementation manner, the second connector 5 is a flexible circuit board.

[0085] As an optional implementation manner, as Figure 5 shown, the flexible circuit board is provided with a first gold finger 51 and a second gold finger 52; wherein, the first gold finger 51 is the first end of the second connector 5 and is used to connect to the male port of the Type-C female end 1; the second gold finger 52 is the second end of the second connector 5 and is used to connect to the negative pole of the power supply.

[0086] Specifically, the thickness of the back reinforcing plate of the first gold finger 51 and the second gold finger 52 is 0.6 mm, the thickness of the flexible cable of the flexible circuit board is 0.1 mm, and the total thickness of the flexible circuit board is 0.7 mm.

[0087] Specifically, the width of the flexible circuit board is 20000 mm, and the length of the flexible circuit board is 3000 mm.

[0088] In an alternative embodiment, the power supply includes a first power supply and a second power supply. The positive electrode of the power supply includes the positive electrode of the first power supply and the negative electrode of the second power supply, and the negative electrode of the power supply includes the negative electrode of the first power supply and the negative electrode of the second power supply.

[0089] Further, the positive electrode of the first light-emitting component KD1 is connected to the positive electrode of the first power supply, and the second end of the second connector 5 is connected to the negative electrode of the first power supply.

[0090] Further, the second light-emitting components KD2 corresponding to two adjacent functional pins are respectively connected to the positive electrode and the negative electrode of the second power supply.

[0091] Specifically, the positive electrode of the second light-emitting component KD2 corresponding to the (2n - 1)-th functional pin is connected to the positive electrode of the second power supply, and the negative electrode of the second light-emitting component KD2 corresponding to the 2n-th functional pin is connected to the negative electrode of the second power supply.

[0092] Optionally, the first power supply and the second power supply are RTC batteries. In actual operation, the number of RTC batteries corresponding to the first power supply and the second power supply can be determined according to the voltage actually required.

[0095] Step S11, when performing an open solder detection on the Type-C female terminal, connect the first end of the first connector to the female port of the Type-C female terminal, and connect the first end of the second connector to the male port of the Type-C female terminal.

[0096] Step S12, if any of the first light-emitting components does not emit light, it is determined that there is an open solder on the Type-C female terminal.

[0097] Step S13, if all the first light-emitting components emit light, it is determined that there is no open solder on the Type-C female terminal.

[0098] As Figure 7 shown, the functional pins of the Type-C female terminal include a bus power pin and other pins. A Type-C female terminal detection method provided in this embodiment further includes the following steps:

[0099] Step S21, when performing a solder bridging detection on the Type-C female terminal, connect the first end of the first connector to the female port of the Type-C female terminal.

[0100] Step S22, if any second light-emitting component corresponding to other pins emits light, it is determined that there is solder bridging in the Type-C female end.

[0101] Step S23, if all the second light-emitting components corresponding to other pins do not emit light, it is determined that there is no solder bridging in the Type-C female end.

[0102] Exemplarily, taking the detection of 2 Type-C female ends as an example, insert the male ports of 2 Type-C male-female adapter data cables into the female ports of the Type-C female ends to be tested respectively, press the switch device to make the switch device conduct, and observe the second light-emitting components connected to other pins and the second light-emitting components connected to the bus power pins in the solder bridging detection component 3. If none of the second light-emitting components connected to other pins emit light and all the second light-emitting components connected to the bus power pins emit light, it is determined that there is no solder bridging in the Type-C female end. If any second light-emitting component connected to other pins emits light, it is determined that there is solder bridging in the Type-C female end. Then, insert the female port of the flexible circuit board (i.e., the first end of the second connector) into the male port of the Type-C female end. If all the first light-emitting components emit light, it is determined that there is no dry joint in the Type-C female end; if any first light-emitting component does not emit light, it is determined that there is no dry joint in the Type-C female end.
