[0090] The present application discloses a connecting wire and a charging and discharging device, which comprises part or all of the technical features of the following embodiments; that is, the connecting wire and the charging and discharging device comprise part or all of the following structures. In one embodiment of the present application, a connecting wire comprises a main connecting part, two auxiliary connecting parts and two wires; wherein the main connecting part is connected to the two auxiliary connecting parts one by one through the two wires in a one-to-one correspondence; the main connecting part and the two auxiliary connecting parts are respectively configured to be detachably connected to the interface socket of the charging and discharging device body, and one of the main connecting part and the two auxiliary connecting parts is also configured to be connected to the plug-in port of the terminal to be charged or the charging port of the charging adapter in a state of being separated from the charging and discharging device body. The above connecting wire, through the cooperation of the main connecting part and the auxiliary connecting part, on the one hand realizes that one interface socket of the charging and discharging device connects two terminals to be charged or two charging adapters through the main connecting part and the auxiliary connecting part, and on the other hand realizes that one charging adapter simultaneously connects the charging and discharging device and the terminal to be charged through one interface socket of the charging and discharging device. Therefore, the connecting wire applicable to realizing bidirectional charging and discharging of the charging and discharging device is provided, which can make the charging and discharging device work in charging or discharging mode without repeatedly switching the connection mode of the charging and discharging device and the connecting wire in use, thereby simplifying the charging and discharging use mode of the charging and discharging device, and also being beneficial to reducing the plugging frequency of the connecting wire relative to the charging and discharging device, thereby reducing the damage probability of the connecting wire and the charging and discharging device due to plugging, and further ensuring the service life of the connecting wire itself and the charging and discharging device. The following will be described in detail in combination with the embodiments of the present application. Figures 1 to 19 The connecting wire and the charging and discharging device will be described in detail.

[0091] In one embodiment of the present application, a charging and discharging device 200 is as follows Figure 1 andFigure 2 As shown, it comprises a charging and discharging device body 210 and a connecting wire 100; wherein the connecting wire 100 is any embodiment connecting wire 100 herein. As an example, the connecting wire 100 is detachably connected to the charging and discharging device body 210.

[0092] In combination Figure 3 and Figure 4 The charging and discharging device body 210 is provided with a first interface socket 211, a second interface socket 212 and a third interface socket 213; the main connecting part 130 of the connecting wire 100 is detachably connected to the third interface socket 213, that is, the main connecting part 130 can be connected to the third interface socket 213, and can also be separated from the third interface socket 213, for example, pulled out of the third interface socket 213, and the remaining embodiments are similar, which will not be repeated. Moreover, the two auxiliary connecting parts of the connecting wire 100 are respectively and one-to-one correspondingly and detachably connected to the first interface socket 211 and the second interface socket 212; as an example, the two auxiliary connecting parts are the first connecting part 110 and the second connecting part 120, that is, the first connecting part 110 of the connecting wire 100 is detachably connected to the first interface socket 211; the second connecting part 120 of the connecting wire 100 is detachably connected to the second interface socket 212.

[0093] Such a structure design, through the cooperation of the connecting wire 100 and the charging and discharging device body 210, on the one hand realizes that one interface socket of the charging and discharging device 200 connects two terminals to be charged 300 or two charging adapters 400 through the main connecting part 130 and the auxiliary connecting part, and on the other hand realizes that one charging adapter 400 connects the charging and discharging device 200 and the terminal to be charged 300 through one interface socket of the charging and discharging device 200, thus realizing bidirectional charging and discharging, without the need to repeatedly switch the connection mode of the charging and discharging device 200 and the connecting wire 100 in use, so as to make the charging and discharging device 200 perform charging work or discharging work, thereby simplifying the charging and discharging use mode of the charging and discharging device 200, and also being beneficial to reducing the plugging frequency of the connecting wire 100 relative to the charging and discharging device 200, thereby reducing the damage probability of the connecting wire 100 and the charging and discharging device 200 due to plugging, and further ensuring the service life of the connecting wire 100 itself and the charging and discharging device 200.

With such a structure design, in the state that the three connecting parts of the connecting wire 100, including the main connecting part 130 and the two auxiliary connecting parts, are connected to the interface sockets, including the first interface socket 211, the second interface socket 212 and the third interface socket 213, the connecting wire 100 has other parts that are not connected to the interface sockets but are inserted into the shell 216, which are referred to as force receiving parts in the related embodiments, including the first force receiving part 111, the second force receiving part 121 and the third force receiving part 131. In this state, when the first force receiving part 111, the second force receiving part 121 or the third force receiving part 131 is subjected to incorrect force, for example, is accidentally touched or is pulled out obliquely, the incorrect force will act on the shell 216 rather than the interface sockets, thereby protecting the interface sockets, and thus further ensuring the service life of the connecting wire 100 itself and the charging and discharging device 200.

[0095] In one of the embodiments, as shown in Figure 5 The charging and discharging device 200 further comprises a rubber plug 220, which is detachably inserted into the first interface socket 211, the second interface socket 212 and the third interface socket 213. In the illustrated embodiment, the rubber plug 220 is integrated, and in other embodiments, the rubber plug 220 can also be split, that is, one rubber plug 220 is arranged for each interface socket, and the three rubber plugs 220 are connected together through an intermediate piece to prevent accidental loss.

[0130] The connection wire 100 is further exemplarily described below. In one of the embodiments, a connection wire 100 as shown in Figure 6 includes a main connection part 130, two auxiliary connection parts and two wires; wherein the main connection part 130 is connected to the two auxiliary connection parts one by one through the two wires respectively; in combination with Figure 3 and Figure 4 , the main connection part 130 and the two auxiliary connection parts are respectively configured to be detachably accessed to the interface socket of the charging and discharging device body 210, and one of the main connection part 130 and the two auxiliary connection parts, in the state of being separated from the charging and discharging device body 210, that is, in the state of being separated from the interface socket, in combination with Figure 14 , Figure 15 and Figure 16 , is also configured to access the plug-in port of the terminal to be charged 300; or in combination with Figure 17 , Figure 18 and Figure 19It is also configured as a charging port for connecting to the charging adapter 400. This structural design, through the cooperation of the main connecting part 130 and the auxiliary connecting part, allows for two charging terminals 300 or two charging adapters 400 to be connected via one interface socket of the charging / discharging device 200 through the main connecting part 130 and the auxiliary connecting part. Simultaneously, it allows one charging adapter 400 to connect to both the charging / discharging device 200 and the charging terminal 300 via one interface socket of the charging / discharging device 200. Therefore, it provides a connecting cable 100 that can be used to achieve bidirectional charging and discharging of the charging / discharging device 200. During use, there is no need to repeatedly switch the connection method between the charging / discharging device 200 and the connecting cable 100, allowing the charging / discharging device 200 to perform charging or discharging operations. This simplifies the charging / discharging usage of the charging / discharging device 200 and reduces the number of times the connecting cable 100 is plugged in and out of the charging / discharging device 200, thereby reducing the probability of damage to the connecting cable 100 and the charging / discharging device 200 due to plugging and unplugging, and thus ensuring the service life of both the connecting cable 100 and the charging / discharging device 200.

[0131] In one embodiment, such as Figure 6 As shown, the two connecting parts are a first connecting part 110 and a second connecting part 120; the two wires are a first wire 101 and a second wire 102; the main connecting part 130 is connected to the first connecting part 110 via the first wire 101, and is also connected to the second connecting part 120 via the second wire 102; combined with Figure 3 and Figure 4 The first connecting portion 110 is configured to be detachably connected to the first interface socket 211 of the charging / discharging device body 210, and the first connecting portion 110, when separated from the first interface socket 211, is as follows: Figure 14 As shown, it is also configured to connect to the first plug-in port 311 of the terminal to be charged 300; or as shown Figure 17 As shown, it is also configured to connect to the first charging port 401 of the charging adapter 400.

[0132] Combination Figure 3 and Figure 4 The second connecting portion 120 is configured to be detachably connected to the second interface socket 212 of the charging / discharging device body 210, and the second connecting portion 120, when detached from the second interface socket 212, is as follows: Figure 15 As shown, it is also configured to connect to the second plug-in port 321 of the terminal to be charged 300; or as shown Figure 18 As shown, it is also configured to connect to a second charging port 402 of the charging adapter 400.

[0133] The main connection portion 130 is configured to be detachably connected to the third interface socket 213 of the charging / discharging device body 210, and when the main connection portion 130 is detached from the third interface socket 213, as...Figure 16 As shown, the main connecting part 130 is further configured to access the third plug-in port 331 of the terminal 300 to be charged; or as shown, the third charging port 403 of the charging adapter 400. Figure 19 As shown, the main connecting part 130 is further configured to access the third plug-in port 331 of the terminal 300 to be charged; or as shown, the third charging port 403 of the charging adapter 400.

[0134] In one embodiment, as shown in Figure 2 and Figure 3 As shown, in the state that the first connecting part 110 accesses the first interface socket 211, the second connecting part 120 accesses the second interface socket 212, and the main connecting part 130 accesses the third interface socket 213, the extension directions of the first connecting part 110, the second connecting part 120 and the main connecting part 130 are parallel to each other, and the first connecting part 110 and the second connecting part 120 are located on the same side of the main connecting part 130; for example, in the state that the first connecting part 110 accesses the first interface socket 211, the second connecting part 120 accesses the second interface socket 212, and the main connecting part 130 accesses the third interface socket 213, the first connecting part 110, the second connecting part 120 and the main connecting part 130 have flush shapes. As an example, the first force receiving part 111, the second force receiving part 121 and the main connecting part 130 are arranged in alignment, and the first interface 112, the second interface 122 and the third force receiving part 131 are arranged in alignment; that is, the first interface 112, the second interface 122 and the third force receiving part 131 have end portions in the same plane, so that the first connecting part 110, the second connecting part 120 and the main connecting part 130 have flush shapes.

[0135] In one embodiment, as shown in Figure 6 and Figure 7 As shown, the first wire 101 and the second wire 102 have the same length; in this embodiment, the first wire 101 and the second wire 102 have the same preset shape, that is, in one embodiment, the first wire 101 and the second wire 102 have the same length, and the first wire 101 and the second wire 102 have the same preset shape. The remaining embodiments are similar, and are not described herein. In one embodiment, as shown in Figure 6 and Figure 7 As shown, the first wire 101 and the second wire 102 each have a pre-bending section 103, so that the first wire 101 and the second wire 102 each have a U-shaped structure. Such a structure design is beneficial to regularize the shape of the connecting wire 100, easy to store, and avoid winding.

[0136] In one embodiment, as shown in Figure 6 and Figure 7As shown, the first wire 101 and the second wire 102 have a joint portion that connects to the main connecting portion 130, and the joint portion has a portion exposed outside the main connecting portion 130. During use, the first connecting portion 110 and the second connecting portion 120 are the most frequently plugged and unplugged. The main connecting portion 130 connects to the first connecting portion 110 via the first wire 101 and to the second connecting portion 120 via the second wire 102. Therefore, this structural design helps to ensure the structural strength of the main connecting portion 130 and the first wire 101 and the second wire 102, thereby ensuring the normal service life of the connecting wire 100.

[0137] In one embodiment, such as Figure 7 As shown, the main connecting part 130 and the two auxiliary connecting parts are all equipped with force-bearing parts and interfaces; combined with Figure 1 and Figure 2 The force-bearing part is configured to be detachably inserted into the housing 216 of the charging / discharging device body 210; the interface is configured to be detachably connected to the interface socket. In this embodiment, the force-bearing part includes a first force-bearing part 111, a second force-bearing part 121 and a third force-bearing part 131, and the interface includes a first interface 112, a second interface 122 and a third interface 132. Specific connection examples are described below.

[0138] In one embodiment, such as Figure 7 As shown, the first connecting part 110 is provided with a first force-bearing part 111 and a first interface 112 connected to each other, the second connecting part 120 is provided with a second force-bearing part 121 and a second interface 122 connected to each other, and the main connecting part 130 is provided with a third force-bearing part 131 and a third interface 132.

[0139] Combination Figure 2 and Figure 4, the first force receiving portion 111, the second force receiving portion 121 and the third force receiving portion 131 are configured to be partially inserted into the shell 216 of the charging and discharging device body 210; in the state that the first force receiving portion 111 is partially inserted into the shell 216, the first interface 112 is configured to be connected to the first interface socket 211; that is, in the state that the first connecting portion 110 is connected to the first interface socket 211, the first force receiving portion 111 has a portion inserted into the shell 216. In the state that the second force receiving portion 121 is partially inserted into the shell 216, the second interface 122 is configured to be connected to the second interface socket 212; that is, in the state that the second interface 122 is connected to the second interface socket 212, the second force receiving portion 121 has a portion inserted into the shell 216. In the state that the third force receiving portion 131 is partially inserted into the shell 216, the third interface 132 is configured to be connected to the third interface socket 213; that is, in the state that the third interface 132 is connected to the third interface socket 213, the third force receiving portion 131 has a portion inserted into the shell 216. In this state, the first force receiving portion 111, the second force receiving portion 121 and the third force receiving portion 131 are not inserted into the first interface socket 211, the second interface socket 212 and the third interface socket 213.

[0140] That is, in the state that the first interface 112 is connected to the first interface socket 211, the first force receiving portion 111 of the first connecting portion 110 is also configured to be partially inserted into the shell 216 of the charging and discharging device body 210; in the state that the second interface 122 is connected to the second interface socket 212, the second force receiving portion 121 of the second connecting portion 120 is also configured to be partially inserted into the shell 216 of the charging and discharging device body 210; in the state that the third interface 132 is connected to the third interface socket 213, the third force receiving portion 131 of the main connecting portion 130 is also configured to be partially inserted into the shell 216 of the charging and discharging device body 210. Exemplarily, on the one hand, this can replace the bearing of external irregular forces, i.e. forces not intentionally performed by the user, by the first force receiving portion 111, the second force receiving portion 121 and the third force receiving portion 131, thereby protecting the first interface 112, the second interface 122, the third interface 132, the first interface socket 211, the second interface socket 212 and the third interface socket 213; on the other hand, this can reduce the pressure intensity of the first force receiving portion 111, the second force receiving portion 121 and the third force receiving portion 131 by increasing the force receiving area, thereby ensuring the design life of the product.

[0141] In one embodiment, the first force receiving portion 111 is also configured to be separated from the charging and discharging device body 210 together with the first interface 112, and the first interface 112 is also configured to be connected to the first plug-in port 311 of the terminal 300 to be charged in the state of being separated from the first interface socket 211, i.e. in the state that the first connecting portion 110 is connected to the first interface socket 211, the first force receiving portion 111 has a portion inserted into the shell 216. Figure 14As shown, or configured to access the first charging port 401 of the charging adapter 400 as shown. Figure 17 As shown.

[0142] The second force receiving part 121 is further configured to separate from the second interface 122 together with the charging and discharging device body 210, and the second interface 122 is further configured to access the second plug-in port 321 of the terminal to be charged 300 in a state of being separated from the second interface socket 212 as shown. Figure 15 As shown, or configured to access the second charging port 402 of the charging adapter 400 as shown. Figure 18 As shown.

[0143] The third force receiving part 131 is further configured to separate from the third interface 132 together with the charging and discharging device body 210, and the third interface 132 is further configured to access the third plug-in port 331 of the terminal to be charged 300 in a state of being separated from the third interface socket 213 as shown. Figure 16 As shown, or configured to access the third charging port 403 of the charging adapter 400 as shown. Figure 19 As shown.

[0144] Such a structure design, on the one hand, is conducive to conveniently plugging and unplugging the first interface 112, the second interface 122 and the third interface 132 through the first force receiving part 111, the second force receiving part 121 and the third force receiving part 131, and on the other hand, is conducive to protecting the first interface 112, the second interface 122 and the third interface 132 accessed in the first interface socket 211, the second interface socket 212 and the third interface socket 213 through the state of the first force receiving part 111, the second force receiving part 121 and the third force receiving part 131 partially inserted into the shell 216, especially the first interface 112, the second interface 122 and the third interface 132 are usually accessed in the first interface socket 211, the second interface socket 212 and the third interface socket 213, so the state of the first force receiving part 111, the second force receiving part 121 and the third force receiving part 131 partially inserted into the shell 216 is conducive to guaranteeing the normal service life of the first interface 112, the second interface 122 and the third interface 132, and also conducive to guaranteeing the normal service life of the first interface socket 211, the second interface socket 212 and the third interface socket 213.

[0145] In one of the embodiments, the first force receiving part 111 is configured to be clamped or abutted against the housing 216 in a state of being partially inserted into the housing 216, the second force receiving part 121 is configured to be clamped or abutted against the housing 216 in a state of being partially inserted into the housing 216, and the third force receiving part 131 is configured to be clamped or abutted against the housing 216 in a state of being partially inserted into the housing 216. With such a structural design, the first force receiving part 111, the second force receiving part 121, and the third force receiving part 131 have a relatively stable positional relationship with the housing 216, so as to further protect the first interface 112, the second interface 122, and the third interface 132, and also protect the first interface socket 211, the second interface socket 212, and the third interface socket 213, and further protect the housing 216, on the premise of protecting the first force receiving part 111, the second force receiving part 121, and the third force receiving part 131 themselves. In addition, the structure also has a dustproof effect.

[0146] In one of the embodiments, as shown in Figure 14 , the first connecting part 110 further comprises a first circuit module 113 arranged in the first force receiving part 111, and the first interface 112 is connected with the first wire 101 through the first circuit module 113; as shown in Figure 15 , the second connecting part 120 further comprises a second circuit module 123 arranged in the second force receiving part 121, and the second interface 122 is connected with the second wire 102 through the second circuit module 123; as shown in Figure 16 , the main connecting part 130 further comprises a third circuit module 133 arranged in the third force receiving part 131, and the third interface 132 is connected with the first wire 101 and the second wire 102 through the third circuit module 133; the third circuit module 133 is configured to individually or jointly with the first circuit module 113 to turn on or turn off the first interface 112 and the third interface 132; the third circuit module 133 is further configured to individually or jointly with the second circuit module 123 to turn on or turn off the second interface 122 and the third interface 132.

[0147] In one of the embodiments, the first interface 112 and the second interface 122 are one of a Type-C interface and a Lightning interface, and the first interface 112 and the second interface 122 are arranged differently. For example, the first interface 112 is a Lightning interface, and the second interface 122 is a Type-C interface.

[0148] In one of the embodiments, one of the first interface 112 and the second interface 122 is arranged the same as the third interface 132, and the other is arranged differently from the third interface 132; for example, the first interface 112 is a Lightning interface, the second interface 122 is a Type-C interface, and the second interface 122 is arranged the same as the third interface 132, i.e., the third interface 132 is also a Type-C interface; at this time, the first interface 112 is arranged differently from the third interface 132. The opposite is also possible. In one of the embodiments, one of the first force receiving part 111 and the second force receiving part 121 is arranged the same as the third force receiving part 131, and the other is arranged differently from the third force receiving part 131.

[0149] The following will continue to combine Figures 1 to 19 to illustrate the connection wire 100 and the charging and discharging device 200.

[0150] The charging and discharging device 200 includes a charging and discharging device body 210 and the connection wire 100. Among them, the charging and discharging device body 210 is provided with a Lightning interface socket as a first interface socket 211, and is also provided with two Type-C interface sockets as a second interface socket 212 and a third interface socket 213 respectively; the connection wire 100 is provided with a Lightning interface corresponding to the Lightning interface socket as a first connection part 110, and is also provided with Type-C interfaces corresponding to the Type-C interface sockets as a second connection part 120 and a main connection part 130 respectively.

[0151] For example, the charging and discharging device 200 or the charging and discharging device body 210 thereof includes but is not limited to the following forms:

[0152] 1. The Lightning interface is inserted into the Lightning interface socket, and the two Type-C interfaces are inserted into the two Type-C interface sockets respectively, at this time, it can play a role of storing the connection wire 100 neatly; at the same time, it is also convenient for the user to hold.

[0153] 2. Both Type-C interfaces are inserted into the corresponding Type-C interface socket, at this time, the charging and discharging device body 210 can discharge externally, i.e., the Lightning interface can charge the Apple device.

[0154] 3. One of the Type-C interfaces is inserted into the corresponding Type-C interface socket, at this time, the charging and discharging device body 210 can discharge externally, i.e., the Lightning interface can charge the Apple device, and the other Type-C interface can charge the Android device.

[0155] 4. Insert the Lightning port into the Lightning port socket, and connect one of the Type-C ports to the adapter. In this case, the charging / discharging device 210 can be charged with the adapter. Alternatively, connect one of the Type-C ports to the Type-C port socket of another charging / discharging device 210. In this case, the other charging / discharging device 210 can be charged through its Type-C port socket, Type-C port, Lightning port, and the Lightning port socket of the first charging / discharging device 210.

[0156] 5. Insert the Lightning port into the Lightning port socket, and insert one of the Type-C ports into the corresponding Type-C port socket. At this time, the Lightning port of the charging / discharging device 210 is disabled by default, and the other Type-C port can charge the Android device. Alternatively, the other Type-C port can be connected to an adapter, and the charging / discharging device 210 can be charged with the adapter. Alternatively, the other Type-C port can be connected to the Type-C port socket of another charging / discharging device 210, and the other charging / discharging device 210 can be charged through the Type-C port socket of the other charging / discharging device 210, the other Type-C port, the Type-C port, and the Type-C port socket of the charging / discharging device 210.

[0157] 6. Lightning interface sockets and / or Type-C interface sockets can be fitted with silicone plugs for aesthetic and dustproof purposes;

[0158] In some embodiments, when one end of the connecting cable 100 is inserted into one of the interface sockets for charging / discharging, the other interface can be sealed with a silicone plug. Of course, when the charging / discharging device body 210 is separated from the connecting cable 100, all three interface sockets can be sealed with silicone plugs.

[0159] In this way, through the cooperation of the charging and discharging device body 210 and the connecting cable 100, the charging and discharging device 200 has bidirectional charging and discharging functions. In actual use, the charging and discharging device 200 can complete charging or discharging without repeatedly switching the connection interface between the charging and discharging device body 210 and the connecting cable 100, thus simplifying the charging and discharging process of the charging and discharging device 200. At the same time, the charging and discharging device 200 can reduce the number of times the connection interface between the connecting cable 100 and the charging and discharging device body 210 is plugged in and out, which can avoid the connection interface of the charging and discharging device body 210 becoming loose, causing damage to the connection interface and rendering the charging and discharging device body 210 unusable, thereby extending the service life of the charging and discharging device 200.

[0160] It should be noted that other embodiments of this application also include connectable wires and charging / discharging devices formed by combining the technical features of the above embodiments.

[0161] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
