Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a first connector, a connector assembly, a power adapter, and an electronic device. Background Art

[0002] When the male connector is plugged into the female connector, electrical energy can be transmitted between the two.

[0003] When the male connector is pulled out from the female connector, the circuit between the power transmission part of the male connector and the power transmission part of the female connector is first disconnected, and then the two are physically separated. However, since the male connector is pulled out from the female connector too quickly, the power transmission part of the male connector and the power transmission part of the female connector have not yet disconnected the circuit, and they enter the physical separation stage, resulting in the power transmission part of the male connector still having a high voltage, while the voltage on the power transmission part of the female connector has been transmitted to the electronic device connected to the female connector, thereby generating a voltage difference between the power transmission part of the male connector and the power transmission part of the female connector to break through the gap between the male connector and the female connector, causing an arc spark between the male connector and the female connector, and even burning the equipment connected to the male connector and / or the female connector.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

"Vertical" does not mean vertical in the strict sense, but is within the tolerance range. "Parallel" does not mean parallel in the strict sense, but is within the tolerance range.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. When a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device.

[0060] All terms used in this application have the same meaning as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0061] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0062] In the related art, when the male connector is pulled out from the female connector, the circuit between the power transmission part of the male connector and the power transmission part of the female connector is first disconnected, and then the two are physically separated. However, since the male connector is pulled out from the female connector too quickly, the power transmission part of the male connector and the power transmission part of the female connector have not yet disconnected the circuit, and they enter the physical separation stage, resulting in the power transmission part of the male connector still having a high voltage, while the voltage on the power transmission part of the female connector has been transmitted to the electronic device connected to the female connector, thereby generating a voltage difference between the power transmission part of the male connector and the power transmission part of the female connector to break through the gap between the male connector and the female connector, so that an arc spark occurs between the male connector and the female connector, and even burns the equipment connected to the male connector and / or the female connector. For example, the power adapter is connected to the electronic device (such as a laptop, tablet computer, or mobile phone) through a male connector and a female connector. Within a short period of time after the male connector of the power adapter is pulled out from the female connector of the electronic device, a large voltage difference is likely to occur between the voltage bus output pin (VBUS pin) of the male connector and the voltage bus input pin (VBUS pin) of the female connector, resulting in arcing and even burning the power adapter and / or the electronic device.

[0063] In the related art, the above problem is solved by increasing the capacitance of the motherboard at the female socket end (such as the motherboard on the electronic device body). Although this method can slow down the speed of pulling apart the male head and the female socket in the process of pulling apart the male head and the female socket, so that the male head has enough time to disconnect the circuit with the female socket, so as to reduce the probability of voltage difference between the male head and the female socket, thereby reducing the arc sparking phenomenon; however, the increase in the motherboard capacitance will cause the device where the male head is located (such as a power adapter) to provide power to the device where the female socket is located (the electronic device body) in the process of providing power, it is necessary to first meet the charging requirements of the motherboard capacitance, which results in the electronic device body being unable to reach the required voltage within the specified time.

[0064] In the present application, a first target functional component 12 that can be switched between a first functional state and a second functional state is provided on the first connector 10 (such as a male head or a female socket), and when the male head and the female socket are in a state of current flow, the first target functional component 12 can be in the first functional state to provide a force opposite to the disconnection direction to the male head or the female socket where it is located, thereby slowing down the disconnection speed of the male head and the female socket, so that the male head has enough time to disconnect the circuit with the female socket, so as to reduce the probability of a voltage difference between the male head and the female socket, thereby reducing the arc sparking phenomenon; and when the male head and the female socket are in a de-energized state, the first target functional component 12 is in the second functional state so as not to provide a force opposite to the disconnection direction, thereby not affecting the normal disconnection between the male head and the female socket in the de-energized state.

[0065] First aspect

[0066] The present application embodiment provides a first connector 10, see Figures 1a to 10 As shown, the first connector 10 may include: a first connection part 11 and a first target functional part 12, the first connection part 11 may be used to connect with the second connection part 21 of the second connector 20, so that the first connection part 11 can transmit electrical energy to the second connection part 21, and the first connection part 11 may have a powered state and a non-powered state; the first target functional part 12 may be in a first functional state when the first connection part 11 is in a powered state, and in a second functional state when the first connection part 11 is in a non-powered state; in the first functional state, the force that separates the first connection part 11 and the second connection part 21 may be a first force; in the second functional state, the force that separates the first connection part 11 and the second connection part 21 may be a second force, and the second force may be smaller than the first force. It should be noted that Figure 2 The first force application direction and the second force application direction correspond to the directions of the forces that need to be applied to the first connector 10 and the second connector 20 when the first connector 10 and the second connector 20 are separated from each other.

[0067] It can also be said that the first connection part 11 and the second connection part 21 can be connected to realize the electrical connection between the first connector 10 and the second connector 20, so that the mutual transmission of electric energy between the first connector 10 and the second connector 20 can be realized through the first connection part 11 and the second connection part 21, and then, when any one of the first connection part 11 and the second connection part 21 is connected to the power supply and when the power supply provides current, the first connection part 11 is in a powered state; on the contrary, when the power supply does not provide current, the first connection part 11 is in a non-powered state. However, when the first connection part 11 is in a powered state, the first target functional part 12 is in a first functional state, and the separation force between the first connection part 11 and the second connection part 21 in the first functional state is relatively large, so as to slow down the speed of separation between the first connector 10 and the second connector 20 when the first connection part 11 is in a powered state, thereby reducing the probability of arc sparking between the first connector 10 and the second connector 20; when the first connection part 11 is not powered, the first target functional part 12 is in a second functional state, and the separation force between the first connection part 11 and the second connection part 21 in the second functional state is relatively small, so as to save effort in separating the first connector 10 and the second connector 20.

[0068] Here, the first connector 10 may be a male connector, and the corresponding second connector 20 may be a female connector; or, the first connector 10 may be a female connector, and the corresponding second connector 20 may be a male connector. In other words, the first target functional component 12 for delaying the unplugging speed between the male connector and the female connector may be set on the male connector or the female connector as needed, so that the restrictions on the setting position can be reduced. The first connector 10 may be set on a power adapter, or on the body of an electronic device such as a laptop, a tablet computer, or a mobile phone.

[0069] The first target functional part 12 may be in contact with the second connector 20 in the first functional state, and the contact surface on the first target functional part 12 may be a rough surface and the contact surface on the second connector 20 may be a rough surface or a non-rough surface, so that the surfaces of the first target functional part 12 and the second connector 20 in contact with each other have a mutual friction force, and in the second functional state, the first target functional part 12 may be separated from the second connector 20 so as not to have a mutual force; the first target functional part 12 may be in the first functional state as follows Figure 4 The first target functional part 12 is shown as being in a state of being connected with the second connector 20 in a concave-convex manner to have a mutual pulling force, and in the second functional state, it can be separated from the second connector 20 to have no mutual interaction force; the first target functional part 12 can be as follows in the first functional state Figure 6 or Figure 8 The second target functional part shown clamping the second connector 20 can be separated from the second target functional part in the second functional state so as to have no interaction force; of course, the first target functional part 12 can also have other settings in the first functional state and the second functional state, which are not listed here one by one.

[0070] In some embodiments, when the first connection portion 11 is in a charged state, the first connection portion 11 can transmit electric energy to the second connection portion 21. In other words, the first connection portion 11 can be connected to a power source so that the electric energy provided by the power source can be transmitted to the second connection portion 21 through the first connection portion 11. For example: the first connector 10 is arranged on a power adapter, and the second connector 20 is arranged on the electronic device body, so that when the power adapter is connected to the power source, and the first connection portion 11 on the power adapter is connected to the second connection portion 21 on the electronic device body, the power adapter can transmit the electric energy provided by the power source to the second connection portion 21; for another example: the first connector 10 is arranged on the electronic device body, and the second connector 20 is arranged on the power adapter, so that when the power adapter is connected to the power source, and the second connection portion 21 on the power adapter is connected to the first connection portion 11 on the electronic device body, the power adapter can transmit the electric energy provided by the power source to the first connection portion 11.

[0071] In some embodiments, see Figures 1a to 6 As shown, the first connector 10 may also include: a first identification part 13, a detection module 14 and a driving module 15. The first identification part 13 can be connected to the first connection part 11 and is used to connect to the second identification part 23 of the second connector 20, so that the first identification part 13 and the second identification part 23 cooperate to confirm the adaptation relationship between the first connector 10 and the second connector 20 connected to each other. When the first connector 10 and the second connector 20 are adapted to each other, the first connection part 11 can transmit electric energy to the second connection part 21; when the first identification part 13 and the second identification part 23 are disconnected, the voltage or current of the first identification part 13 decreases, and after the first identification part 13 and the second identification part 23 are disconnected, the voltage or current of the first connection part 11 begins to decrease; the detection module 14 is connected to the first identification part 13 and can detect the current or voltage of the first identification part 13; the driving module 15 is electrically connected to the detection module 14 and the first connection part 11, and when the detection module 14 detects that the current or voltage of the first identification part 13 decreases, the first target functional part 12 is driven to be in the first functional state through the electric energy of the first connection part 11.

[0072] It can also be said that the first identification portion 13 on the first connector 10 and the second identification portion 23 on the second connector 20 can be connected to each other for mutual identification, and then confirm whether the first connector 10 and the second connector 20 are compatible with each other, and when they are compatible with each other, the first connection portion 11 can transmit electric energy to the second connection portion 21; and when they are not compatible with each other, after the first connection portion 11 of the first connector 10 and the second connection portion 21 of the second connector 20 are connected to each other, the first connection portion 11 cannot transmit electric energy to the second connection portion 21. At this time, the first identification portion 13 can send an incompatible signal to the user, so that the user can separate the incompatible first connector 10 and the second connector 20 in time. In this way, it can avoid the situation where the first connection portion 11 and the second connection portion 21 can be physically connected to each other but cannot transmit electric energy for a long time. When the first identification part 13 and the second identification part 23 adapted to each other switch from the connected state to the disconnected state, the detection module 14 detects that the voltage or current of the first identification part 13 drops. At this time, the first connection part 11 has not received the circuit disconnection signal sent by the first identification part 13, so that the first connection part 11 still has voltage or current to drive the first target functional part 12 to the first functional state, thereby delaying the separation speed of the first connector 10 and the second connector 20, and providing enough time for the first connection part 11 to receive the circuit disconnection signal provided by the first identification part 13. Among them, the first identification part 13 and the second identification part 23 can both be CC pins.

[0073] Here, see Fig.10As shown, the input end of the detection module 14 can be connected to the first identification part 13, and the output end can be connected to the control module 15, and the detection module 14 can include a comparison circuit and at least one of a voltage detection circuit and a current detection circuit. The voltage detection circuit or the current detection circuit detects the voltage or current of the first identification part 13, and the comparison circuit compares the detected voltage or current with the voltage or current before the first identification part 13 and the second identification part 23 are disconnected. When the comparison result is a decrease, a signal is output to the drive module 15, and the drive module 15 starts to control the transmission of electric energy from the first connection part 11 to the first target functional part 12 to put the first target functional part 12 in the first functional state.

[0074] In some embodiments, see Figure 1a , Figure 1b and Figure 2 As shown, the first connection part 11 is used to cover the second connection part 21 relative to connect; the first identification part 13 is used to cover the second identification part 23 relative to connect; wherein, when the relative coverage area of ​​the first identification part 13 and the second identification part 23 is reduced, the relative coverage area of ​​the first connection part 11 and the second connection part 21 can be reduced, and after the relative coverage area of ​​the first identification part 13 and the second identification part 23 continues to decrease until they are disconnected from each other, the relative coverage area of ​​the first connection part 11 and the second connection part 21 continues to decrease. In other words, when the first connector 10 and the second connector 20 are connected, the first connection part 11 and the second connection part 21 can be relatively covered to be connected, and the first identification part 13 and the second identification part 23 can be relatively covered to be connected; and when the first connector 10 and the second connector 20 switch from the connected state to the disconnected state (for example: the user separates the first connector 10 and the second connector 20), the coverage area of ​​the first identification part 13 and the second identification part 23 gradually decreases, and at the same time, the relative coverage area of ​​the first connection part 11 and the second connection part 21 also gradually decreases, and when the first identification part 13 and the second identification part 23 are not relatively covered to be disconnected, the first connection part 11 and the second connection part 21 still have partial coverage to be connected, and the partial coverage is also gradually reduced until it is not covered to be disconnected. Thus, when the first identification part 13 and the second identification part 23 are disconnected, the first connection part 11 still has electrical energy to provide to the first target functional part 12, so that the first target functional part 12 provides a force opposite to the pulling-off direction to the second connector 20, thereby slowing down the speed of separation between the first connector 10 and the second connector 20, and further reducing the probability of arcing between the first connector 10 and the second connector 20. For example: see Figure 1a , Figure 1b and Figure 2As shown, in the connection direction between the first connector 10 and the second connector 20, the length of the first connection portion 11 is greater than the length of the first identification portion 13, so that the length difference between the first connection portion 11 and the first identification portion 13 can be utilized to conveniently place the first target functional part 12 in the first functional state.

[0075] Here, the first connection part 11 and the first identification part 13 can both be located on the first side of the first connector 10, and the second connection part 21 and the second identification part 23 can both be located on the first side of the second connector 20. In this way, the first side of the first connector 10 and the first side of the second connector 20 can realize the mutual connection of the first connection part 11 and the second connection part 21 by mutual plugging, mutual abutment, etc., while the first identification part 13 and the second identification part 23 are connected to each other.

[0076] In some embodiments, see Figures 2 to 6 As shown, the driving module 15 may include: a controller 151, a control switch 152 and a magnetic component 153. The controller 151 may be electrically connected to the detection module 14, and the control switch 152 may be electrically connected to the controller 151, the first connecting part 11 and the magnetic component 153 respectively; when the detection module 14 detects a current or voltage drop in the first identification part 13, the controller 151 may control the control switch 152 to turn on so that the first connecting part 11 transmits an electrical signal to the magnetic component 153 to generate a magnetic field; wherein the first target functional component 12 may be a magnetic component and be located in the magnetic field, and after the magnetic component 153 generates a magnetic field, the first target functional component 12 is used to contact the second target functional component 22 of the second connector 20 under the action of the magnetic attraction force or repulsion force provided by the magnetic field. In other words, when the first connector 10 and the second connector 20 are separated from each other, the voltage or current of the first identification part 13 decreases. At this time, the detection module 14 detects the information that the voltage or current of the first identification part 13 decreases, and the controller 151 connected to the detection module 14 can control the control switch 152 to turn on, so that the first connection part 11, which is still connected to the second connection part 22 with current, transmits an electrical signal to the magnetic component 153, so that the magnetic component 153 generates a magnetic field. Since the first target functional component 12 is a magnetic component and is located in the magnetic field, it can move toward the second target functional component 22 under the action of the adsorption force or repulsion force of the magnetic field and contact the second target functional component 22; then when the separation continues, after the electric energy between the first connection part 11 and the second connection part 22 is consumed, the magnetic field disappears, and the first target functional component 12 is reset, and the male head can be easily pulled out from the female socket without the risk of sparks.

[0077] Here, see Fig.10As shown, the input end of the detection module 14 can be connected to the first identification part 13, and the output end can be connected to the controller 151 of the control module 15, and the detection module 14 can include a comparison circuit and at least one of a voltage detection circuit and a current detection circuit. The voltage detection circuit or the current detection circuit detects the voltage or current of the first identification part 13, and the comparison circuit compares the detected voltage or current with the voltage or current before the first identification part 13 and the second identification part 23 are disconnected. When the comparison result is reduced, the output signal is sent to the controller 151 of the driving module 15. At this time, the controller 151 can control the control switch 152 to turn on (for example, sending a high level signal or a low level signal to the control switch 152, etc., and the control switch 15 2 can be a PMOS tube or an NMOS tube, etc.), so that the magnetic component 153 and the second connection part 22 are electrically connected through the control switch 152 after being turned on, and the first connection part 11 with current transmits an electrical signal to the magnetic component 153, so that the magnetic component 153 generates a magnetic field due to electromagnetism. Since the first target functional component 12 is a magnetic component and is located in the magnetic field, it can move toward the second target functional component 22 under the action of the adsorption force or repulsion force of the magnetic field and contact the second target functional component 22; then, when the electric energy between the first connection part 11 and the second connection part 22 is consumed in the process of continuing to be pulled out, the magnetic field disappears, and the first target functional component 12 is reset, so that the male head can be easily pulled out from the female seat without the risk of sparks. The magnetic component 153 can be a section of wire that can generate a magnetic field after conducting current, or it can be a coil that can generate a magnetic field after conducting current, or it can be other settings.

[0078] It can be understood that, when the first target functional component 12 of the first connector 10 and the second target functional component 22 of the second connector 20 are in contact with each other, when the first connector 10 and the second connector 20 are pulled apart from each other, there is at least friction between the first target functional component 12 and the second target functional component 22 to slow down the pulling-off speed of the first connector 10 and the second connector 20, and the friction belongs to the first force.

[0079] Second aspect

[0080] The present application embodiment provides a connector assembly, see Figures 1a to 10As shown, the connector assembly may include: a first connector 10 and a second connector 20, the first connector 10 may include: a first connection part 11 and a first target functional part 12; the second connector 20 includes: a second connection part 21; the first connection part 11 may be used to connect with the second connection part 21, so that the first connection part 11 can transmit electrical energy to the second connection part 21, and the first connection part 11 has a powered state and a non-powered state; the first target functional part 12 can be in a first functional state when the first connection part 11 is in a powered state, and can be in a second functional state when the first connection part 11 is in a non-powered state; in the first functional state, the force separating the first connection part 11 and the second connection part 21 may be a first force; in the second functional state, the force separating the first connection part 11 and the second connection part 21 may be a second force, and the second force is smaller than the first force.

[0081] It can also be said that the first connection part 11 and the second connection part 21 can be connected to realize the electrical connection between the first connector 10 and the second connector 20, so that the mutual transmission of electric energy between the first connector 10 and the second connector 20 can be realized through the first connection part 11 and the second connection part 21, and then, when any one of the first connection part 11 and the second connection part 21 is connected to the power supply and when the power supply provides current, the first connection part 11 is in a powered state; on the contrary, when the power supply does not provide current, the first connection part 11 is in a non-powered state. However, when the first connection part 11 is in a powered state, the first target functional part 12 is in a first functional state, and the separation force between the first connection part 11 and the second connection part 21 in the first functional state is relatively large, so as to slow down the speed of separation between the first connector 10 and the second connector 20 when the first connection part 11 is in a powered state, thereby reducing the probability of arc sparking between the first connector 10 and the second connector 20; when the first connection part 11 is not powered, the first target functional part 12 is in a second functional state, and the separation force between the first connection part 11 and the second connection part 21 in the second functional state is relatively small, so as to save effort in separating the first connector 10 and the second connector 20.

[0082] In some embodiments, see Figures 2 to 9 As shown, the second connector 20 may further include: a second target functional component 22 ; in the first functional state, the first target functional component 12 and the second target functional component 22 may be mutually limited.

[0083] For example, when the first target functional component 12 switches from the second functional state to the first functional state, at least a part of the first target functional component 12 changes position, and after the position changes, it can be concave-convexly matched or clamped with the second target functional component 22, so that when the first connector 10 and the second connector 20 are separated from each other to generate a force moving away from each other, the first target functional component 12 and the second target functional component 22 have a pulling force that brings them closer to each other, so as to delay the force when the first connector 10 and the second connector 20 are separated from each other.

[0084] In one example, see Figure 3 and Figure 4 As shown, the first target functional part 12 on the first connector 10 may have a convex part, and the second target functional part 22 on the second connector 20 may have a concave part. When the detection module 14 does not detect the voltage or current drop of the first identification part 13, the convex part and the concave part are separated from each other; when the detection module 14 detects the voltage or current drop of the first identification part 13, it means that the first connector 10 and the second connector 20 are in the process of being pulled apart from each other. At this time, under the action of the driving module, the convex part moves into the concave part to provide a force for the first connector 10 and the second connector 20 to approach each other, so as to delay the separation speed of the first connector 10 and the second connector 20; wherein, the convex part may be a triangle or other easy-to-come-from shape, or may be a material that is easy to deform and easy to come apart, so as to achieve the separation of the first connector 10 and the second connector 20 when the separation force is greater, so as not to affect the purpose of separating the first connector 10 and the second connector 20. Here, it can also be an opposite setting, that is, the first target functional part 12 is a concave part, and the second target functional part 22 is a convex part. The first connector 10 in this example can be arranged on a power adapter, or on an electronic device body such as a notebook computer, a tablet computer, a mobile phone, etc.

[0085] For another example, see Figures 5 to 9As shown, the first target functional part 12 on the first connector 10 can be a pair of clamping arms, and the second target functional part 22 on the second connector 20 can be a plate body. When the detection module 14 does not detect a voltage or current drop of the first identification part 13, the clamping arms and the plate body are separated from each other; when the detection module 14 detects a voltage or current drop of the first identification part 13, it means that the first connector 10 and the second connector 20 are in the process of being pulled apart from each other. At this time, under the action of the driving module, the clamping arms clamp the plate body to provide a force for the first connector 10 and the second connector 20 to approach each other, so as to delay the first connector 10 and the second connector 20 from being pulled apart. 20 separation speed; wherein, the two surfaces of the plate body to be clamped may be provided with arc-shaped protrusions or arc-shaped grooves, and the clamping arm may be hooked on the protrusions or grooves to increase the clamping force, and the arc-shaped setting can achieve the separation of the first connector 10 and the second connector 20 when the separation force is greater, so as not to affect the purpose of separation of the first connector 10 and the second connector 20; of course, the parts clamped to each other may also be elastic materials to deform during separation, so as to achieve the separation of the first connector 10 and the second connector 20 when the separation force is greater, so as not to affect the purpose of separation of the first connector 10 and the second connector 20. Here, the opposite setting may also be possible, that is, the first target functional part 12 may be the plate body, and the second target functional part 22 may be the clamping arm. The first connector 10 in this example may be provided on a power adapter, or on the body of an electronic device such as a laptop computer, a tablet computer, or a mobile phone.
