The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0038] like Figure 1-2 As shown, a connector 10 according to an embodiment includes: a housing 100 and a tongue assembly 120, wherein the housing 100 is provided with an inner cavity 101 having an opening; the tongue assembly 120 is movably matched with the housing 100, and the tongue assembly 120 has a first position and a second position. The tongue assembly 120 includes a connecting component 210, and when the tongue assembly 120 is in the first position, the connecting component 210 is located in the inner cavity 101, and the connecting component 210 and the housing 100 are defined as a female seat (such as Figure 5When the tongue assembly 120 is in the second position, at least part of the connecting member 210 extends out of the inner cavity 101 from the opening, and the connecting member 210 is defined as a male seat (such as Figure 6 shown).

[0039] like Figure 2-3 As shown, specifically, the housing 100 includes an upper shell 110 and a lower shell 120, the upper shell 110 is connected to the lower shell 120 and forms an inner cavity 101 with an opening, and the upper shell 110 and the lower shell 120 can be fixed together by ultrasonic welding or snap connection. The connecting component 210 includes a rubber core 211 and a conductive terminal 212 inserted on the rubber core 211; when the tongue assembly 120 is in the first position, the connecting component 210 is located in the inner cavity 101, and the connecting component 210 cooperates with the upper shell 110 to define a female seat, which can be connected to a male seat (such as a USB flash drive); when the tongue assembly 120 is in the second position, at least part of the connecting component 210 extends out of the inner cavity 101 from the opening, and the connecting component 210 is defined as a male seat, which can be inserted into the female seat and connected to the female seat (such as a USB female seat).

[0040] like Figure 2 As shown, more specifically, the tongue assembly 120 also has a limiting portion 2110. When the tongue assembly 120 is in the second position, the limiting portion 2110 extends out of the inner cavity 101 of the shell 100. The limiting portion 2110 is used to cooperate with the outer shell of the female socket to prevent the connecting component 210 from shaking in the female socket.

[0041] In the above-mentioned connector 10, the male socket and the female socket of the connector 10 can be switched by changing the position of the tongue assembly 120, and can be used to connect with different electronic devices to meet the different needs of customers and have complete functions.

[0042] Furthermore, the tongue assembly 120 is slidably connected to the housing 100, so that the tongue assembly 120 can move back and forth between the first position and the second position. When the tongue assembly 120 is in the first position, the connecting component 210 is located in the inner cavity 101, and the tongue assembly 120 can be slid to the second position by sliding the tongue assembly 120, so that the connecting component 210 extends from the inner cavity 101, so that the connecting component 210 is defined as a male seat; similarly, when the tongue assembly 120 is in the second position, the tongue assembly 120 can be slid to the first position, so that the connecting component 210 moves into the inner cavity 101, so that the connecting component 210 and the housing 100 are defined as a female seat.

[0043] In another embodiment, a roller is disposed between the tongue assembly 120 and the housing 100 , and the tongue assembly 120 is rollingly connected to the housing 100 , so that the tongue assembly 120 can move back and forth between the first position and the second position.

[0044] like Figure 2 , 10 As shown, in one embodiment, the housing 100 is further provided with a first limiting hole 102 communicating with the inner cavity 101, and the tongue assembly 120 further includes a transmission component 220 fixedly connected to the connecting component 210, and the transmission component 220 is limitedly matched with the first limiting hole 102 when the tongue assembly 120 is in the first position. The transmission component 220 is used to controllably drive the connecting component 210 to move, so that the entire tongue assembly 120 moves back and forth between the first position and the second position. And when the tongue assembly 120 is in the first position, the transmission component 220 is limitedly matched with the first limiting hole 102, so as to achieve the limiting of the connecting component 210 and keep the connecting component 210 in the inner cavity 101 of the housing 100.

[0045] And / or the housing 100 is further provided with a second limiting hole 103 communicating with the inner cavity 101, and the transmission component 220 is limitedly matched with the second limiting hole 103 when the tongue assembly 120 is in the second position. When the tongue assembly 120 is in the second position, the transmission component 220 is limitedly matched with the second limiting hole 103, thereby realizing the limiting of the connecting component 210, and keeping the connecting component 210 at least partially extending out of the inner cavity 101 of the housing 100.

[0046] Specifically, the shell 100 is provided with a first limiting hole 102 connected to the inner cavity 101, a second limiting hole 103 connected to the inner cavity 101, and a guide hole 104 connected to the inner cavity 101. The first limiting hole 102 and the second limiting hole 103 are arranged at intervals, and the guide hole 104 is connected to the first limiting hole 102 and the second limiting hole 103; the transmission component 220 is limitedly matched with the first limiting hole 102 when the tongue assembly 120 is in the first position, and the transmission component 220 is limitedly matched with the second limiting hole 103 when the tongue assembly 120 is in the second position, and the guide hole 104 is guided and matched with the transmission component 220, so that the tongue assembly 120 can move back and forth between the first position and the second position.

[0047] More specifically, the first limiting hole 102 and the second limiting hole 103 are round holes, and the guide hole 104 is a strip hole. The first limiting hole 102 and the second limiting hole 103 are arranged at intervals, and the guide hole 104 is located between the first limiting hole 102 and the second limiting hole 103, and the two ends of the guide hole 104 are respectively connected to the first limiting hole 102 and the second limiting hole 103, the transmission component 220 is fixedly connected to the tongue assembly 120, and the transmission component 220 can extend into the channel formed by the first limiting hole 102, the second limiting hole 103 and the guide hole 104, and move to the first limiting hole 102 or the second limiting hole 103 through the guide hole 104. When the transmission component 220 moves to the first limiting hole 102, the transmission component 220 abuts against the hole wall of the first limiting hole 102 to achieve the limiting of the transmission component 220; when the transmission component 220 moves to the second limiting hole 103, the transmission component 220 abuts against the hole wall of the second limiting hole 103 to achieve the limiting of the transmission component 220.

[0048] like Figure 2-3 As shown in FIG. 10 , in one embodiment, the transmission component 220 includes a first side wall 221 for contacting one side wall of the guide hole 104, and a second side wall 222 for contacting the other side wall of the guide hole 104. The first side wall 221 and / or the second side wall 222 are elastic components so that the transmission component 220 can enter the guide hole 104 from the first limiting hole 102 and / or the second limiting hole 103 and move in the guide hole 104.

[0049] Specifically, the first limiting hole 102 and the second limiting hole 103 are round holes, the guide hole 104 is a strip hole, the first limiting hole 102 and the second limiting hole 103 are arranged at intervals, the guide hole 104 is located between the first limiting hole 102 and the second limiting hole 103, and the two ends of the guide hole 104 are respectively connected to the first limiting hole 102 and the second limiting hole 103, and the width of the guide hole 104 is smaller than the diameter of the first limiting hole 102 and the second limiting hole 103. When the transmission component 220 is located in the first limiting hole 102 or the second limiting hole 103, the first side wall 221 and the second side wall 222 maintain their initial state, and the first limiting hole 102 or the second limiting hole 103 can limit the movement of the transmission component 220; when it is necessary to move the tongue assembly 120 from the first position to the second position or from the second position to the first position, the first side wall 221 and / or the second side wall 222 can be deformed under the action of the hole wall of the guide hole 104, so that the maximum distance between the first side wall 221 and the second side wall 222 is reduced, so that the transmission component 220 can penetrate into the guide hole 104.

[0050] More specifically, the first side wall 221 and the second side wall 222 cooperate to form a non-closed annular structure, the first side wall 221 and the second side wall 222 are spaced apart and arranged opposite to each other, and both the first side wall 221 and the second side wall 222 are elastic components. In this way, when the transmission component 220 moves in the guide hole 104, the force on the transmission component 220 is more uniform, avoiding being crushed.

[0051] like Figure 2 , 7 As shown, in one embodiment, the connector 10 further includes an operating unit 300, which is connected to the tongue assembly 120, and the operating unit 300 is used to control the tongue assembly 120 to move back and forth between the first position and the second position.

[0052] Specifically, the operating unit 300 is connected to the transmission component 220 , and the user is used to change the position of the tongue assembly 120 by manipulating the operating unit 300 .

[0053] like Figure 2 , 7 As shown, in one embodiment, the operating unit 300 includes a sliding portion 310 located outside the inner cavity 101, a connecting portion 320 connected to the sliding portion 310, and the connecting portion 320 passes through a channel formed by the first limiting hole 102, the second limiting hole 103 and the guide hole 104 and is connected to the tongue assembly 120. The operator can move the sliding portion 310 outside the housing 100, so that the tongue assembly 120 slides back and forth between the first position and the second position, which is convenient for operation.

[0054] Specifically, the sliding portion 310 is a slider, and the connecting portion 320 is a connecting rod. The connecting rod and the slider may be an integrally formed structure, or may be fixedly connected by means of buckles or screws.

[0055] like Figure 7-8 As shown, further, the connecting portion 320 has a supporting portion 321, and an accommodating space is formed between the first side wall 221 and the second side wall 222. The connecting portion 320 can be telescopically arranged in the accommodating space, and the connecting portion 320 has a third position and a fourth position; when the connecting portion 320 is in the third position, the supporting portion 321 is used to support the first side wall 221 and the second side wall 222, so that the first side wall 221 and the second side wall 222 are limitedly matched with the hole wall of the first limiting hole 102 or the second limiting hole 103, and when the connecting portion 320 is in the fourth position, the first side wall 221 and the second side wall 222 can move closer to each other under the action of the hole wall of the guide hole 104.

[0056] It should be noted that the connecting portion 320 can be moved to a third position (eg Figure 7 ) and the fourth position (as shown Figure 8), does not mean that the connecting portion 320 has a third position and a fourth position relative to the accommodating space.

[0057] like Figure 7-10 As shown, when the tongue assembly 120 is in the first position, the transmission component 220 is inserted into the first limiting hole 102, and when the connecting portion 320 is in the third position, the supporting portion 321 is supported between the first side wall 221 and the second side wall 222. The first side wall 221 and the second side wall 222 cannot be deformed to a size that can pass through the guide hole 104 under the action of external force. In this case, the first side wall 221 and the second side wall 222 can abut against the hole wall of the first limiting hole 102 to achieve the limitation of the tongue assembly 120. When the tongue assembly 120 is in the first position and when the connecting component 210 is in the fourth position, the first side wall 221 and the second side wall 222 can be brought close to each other. In this case, the tongue assembly 120 can be moved toward the second position by moving the slider, and in the initial stage of the tongue assembly 120 moving from the first position to the second position, the hole wall of the guide hole 104 will squeeze the first side wall 221 and the second side wall 222, so that the maximum distance between the first side wall 221 and the second side wall 222 is reduced until the transmission component 220 can pass through the guide hole 104.

[0058] like Figure 7-9 As shown, in one embodiment, the connector 10 further includes an elastic member 400, and two ends of the elastic member 400 are respectively connected to the connecting portion 320 and the transmission member 220, so that the connecting portion 320 has a tendency to move toward the third position. The elastic member 400 is used to restore the connecting portion 320.

[0059] Specifically, the elastic member 400 is a spring, which is disposed in the accommodation space formed by the first side wall 221 and the second side wall 222 , and one end of the elastic member 400 abuts against the transmission component 220 , and the other end abuts against the supporting portion 321 .

[0060] When the tongue assembly 120 is in the first position and the connecting part 320 is in the third position, after pressing the sliding part 310, the connecting part 320 moves to the fourth position, the elastic member 400 is compressed, and then the sliding part 310 is slid again, and the first side wall 221 and the second side wall 222 of the transmission part 220 are compressed until they can enter the guide hole 104. When the transmission part 220 passes through the guide hole 104 and the tongue assembly 120 moves to the second position, the first side wall 221 and the second side wall 222 return to their natural state, the elastic member 400 returns to their natural state, and the transmission part 220 passes through the second limiting hole 103. At this time, the connecting part 210 is defined as a male seat, which can be connected to the female seat.

[0061] It can be understood that the process of the tongue assembly 120 moving from the second position to the first position is similar to the above, and will not be repeated here.

[0062] like Figure 4-6 As shown, an embodiment further relates to a data cable 1 , comprising the connector 10 as described above and a wire 20 connected to the connector 10 .

[0063] In the above-mentioned data cable 1, the male socket and the female socket of the connector 10 can be switched by changing the position of the tongue component 120, and can be used to connect with different electronic devices to meet the different needs of customers and have complete functions.

[0064] Furthermore, the data cable 1 also includes a connector male socket 30, which can be a Type C male socket, a micro USB male socket, or a Lightning male socket. One end of the wire 20 is connected to the above-mentioned connector 10, and the other end is connected to the connector male socket 30.

[0065] Specifically, the data cable also includes a flexible flat cable 40 and a PCB (Printed Circuit Board) 50. One end of the flexible flat cable 40 is electrically connected to the solder pin of the conductive terminal 212, and the other end is electrically connected to one end of the PCB 50. The other end of the PCB 50 is electrically connected to one end of the connector-free male socket 30 of the wire 20. The flexible flat cable 40 can ensure that the tongue assembly 120 slides automatically in the inner cavity 101 of the shell 100 without affecting the electrical connection.

[0066] In another embodiment, the flexible flat cable 40 is directly electrically connected to the end of the wire 20 without the connector male socket 30 .

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
