the contact pieces 2 are arranged in the shell 1 and correspond to the jacks one by one; each contact element 2 comprises a first elastic arm 21 and a second elastic arm 22 which are arranged oppositely, each first elastic arm 21 and each second elastic arm 22 comprise a contact area 23 used for being in contact with the plug pin 101 and a supporting area 24 positioned outside the contact area 23, at least one first coil 25 is sleeved on the supporting area 24 of the first elastic arm 21, second coils 26 corresponding to the first coils 25 in a one-to-one mode are sleeved on the supporting area 24 of the second elastic arm 22, and each pair of the first coils 25 and the second coils 26 corresponding to each other are arranged oppositely;

the current adjusting assembly 3 is arranged in the shell 1 and used for adjusting the current direction in the coils, and in the process that the plug pins 101 are inserted into or pulled out of the two corresponding contact areas 23, the current adjusting assembly 3 controls the current to be led into each pair of the first coil 25 and the second coil 26 so as to enable the two contact areas 23 to be far away from each other; when the pin 101 is inserted into position between the two corresponding contact areas 23, the current regulating assembly 3 controls the current to flow through each pair of the first coil 25 and the second coil 26, so that the two contact areas 23 are close to each other.

When the socket provided by the embodiment is used for charging the electronic device, in the process that the plug pins 101 of the plug 100 of the electronic device are inserted into or pulled out of the two contact areas 23 of the corresponding contact element 2, the current regulating assembly 3 can control the current to be introduced into each pair of the first coil 25 and the second coil 26, so that the two contact areas 23 are far away from each other, the process of plugging and unplugging the plug 100 on the socket by a user is more labor-saving, and the plugging and unplugging are more convenient; when the pin 101 is inserted in place between the two contact areas 23 of the corresponding contact element 2, the current regulating assembly 3 can control the current to flow in each pair of the first coil 25 and the second coil 26, so that the two contact areas 23 are close to each other, thereby ensuring the reliable connection between the pin 101 and the contact element 2.

The jacks on the shell 1 are used for being matched with the plug pins 101 of the plug 100, and when the shell 1 is arranged, a group of jacks matched with the plug pins 101 of one plug 100 can be arranged on the shell 1; multiple sets of jacks may also be provided, each set of jacks being adapted to mate with a pin 101 of a plug 100.

Further, when a plurality of groups of jacks are arranged on the socket, the number of the jacks in each group may be the same or different, for example: the number of the jacks in one group is two, and the number of the jacks in the other group is three; the number of the jacks in each group can be two or three.

The contact members 2 may be copper sheets, each of the contact members 2 includes a first elastic arm 21 and a second elastic arm 22 which are oppositely arranged, and optionally, as shown in fig. 2 and 3, one supporting region 24 of the first elastic arm 21 and a corresponding supporting region 24 of the second elastic arm 22 in each of the contact members 2 may be connected with each other, so that each of the contact members 2 is a unitary structure.

The contact 2 with one end open in the length direction and one end connected is not only convenient to be arranged in the shell 1, but also has small influence on the mutual approaching or separating of the two contact areas 23, and is beneficial to ensuring the performance of the socket provided by the embodiment.

In the process of inserting or pulling out the pin 101 from between the two corresponding contact areas 23, the current adjusting assembly 3 controls the current to be conducted into each pair of the first coil 25 and the second coil 26, so that the two contact areas 23 are away from each other, specifically, the current adjusting assembly 3 can control the currents conducted into the first coil 25 and the second coil 26 corresponding to each other in the same direction, and the directions of the currents conducted into the two first coils 25 which are not in the same pair may be the same or opposite.

After the pin 101 is inserted in place between the two corresponding contact areas 23, the current adjusting assembly 3 controls the current to flow into each pair of the first coil 25 and the second coil 26, so that the two contact areas 23 are close to each other, specifically, after the pin 101 is inserted in place between the two corresponding contact areas 23, the current adjusting assembly 3 may control the currents flowing into the first coil 25 and the second coil 26 corresponding to each other in opposite directions, and the directions of the currents flowing into the first coils 25 not in the same pair may be the same or opposite.

With reference to fig. 2 and fig. 3, in order to make the two contact regions 23 move more smoothly in the process of approaching or separating from each other when the contact element 2 is disposed, along the length direction of the first elastic arm 21, support regions 24 may be formed on both sides of the contact region 23 in the first elastic arm 21; along the length of the second resilient arm 22, support regions 24 may be formed on both sides of the contact region 23 in the second resilient arm 22.

Further, in order to make the moving direction of the two contact areas 23 move closer to or away from each other more accurate, the second elastic arm 22 may be a straight arm, in the same contact 2, the contact area 23 of the first elastic arm 21 is parallel to the second elastic arm 22, and the two support areas 24 of the first elastic arm 21 are disposed obliquely with respect to the contact area 23 and extend from the contact area 23 to the direction away from the second elastic arm 22.

In order to make the two contact regions 23 move more smoothly in the process of approaching or separating from each other, in a specific technical solution, each supporting region 24 of the first elastic arm 21 is sleeved with at least one first coil 25, and each supporting region 24 of the second elastic arm 22 is sleeved with a second coil 26 corresponding to the first coil 25 one to one.

As shown in fig. 4 and 5, in one implementation, the current regulating assembly 3 may include a first switch 31, where the first switch 31 is located between the jack and the corresponding contact 2, and is used to control the current passing through each pair of the first coil 25 and the second coil 26 before the plug pin 101 is inserted into the corresponding contact 2, so as to move the two contact regions 23 away from each other. Specifically, the first switch 31 may be a micro switch.

The first switch 31 controls the current passing through each pair of the first coil 25 and the second coil 26, so that the two contact areas 23 are far away from each other, the design is simplified, and the assembly and maintenance of the socket are facilitated.

In particular, in an embodiment, each contact 2 corresponds to a first switch 31.

Further, the current regulating assembly 3 comprises a second switch 32, the second switch 32 being located at the bottom of the housing 1 and being configured to control the current passing through each pair of the first coil 25 and the second coil 26 after the pin 101 is inserted into the corresponding contact 2, so as to bring the two contact regions 23 into proximity with each other.

The second switch 32 controls the current passing through each pair of the first coil 25 and the second coil 26, so that the two contact regions 23 are close to each other, and the design is simplified, and the assembly and maintenance of the socket are facilitated.

In particular, in an embodiment, each contact 2 corresponds to a second switch 32, and the second switch 32 is located between the corresponding first elastic arm 21 and the corresponding second elastic arm 22.

Optionally, the second switch 32 is also used to control the current passing through each pair of the first coil 25 and the second coil 26 when the pin 101 is pulled out, so as to move the two contact areas 23 away from each other.

In a specific implementation manner, the second switch 32 includes a controller and a contact electrically connected to the controller, after the first switch 31 is triggered, when the contact is triggered for the first time, the controller controls current to be conducted to each pair of the first coil 25 and the second coil 26, so that the two contact regions 23 are close to each other; when the contact is activated for the second time after the first switch 31 is activated, the controller controls the current to flow in each pair of the first coil 25 and the second coil 26 so as to move the two contact areas 23 away from each other. Specifically, the controller may be a single chip microcomputer.

Optionally, with continued reference to fig. 4 and 5, the plug 100 includes a body and a plug pin 101 disposed on the body, the top of the housing 1 is provided with a buffer assembly 4, and when the plug 100 is plugged in place in the socket, the body of the plug 100 abuts against the buffer assembly 4. Specifically, the pin 101 triggers the second switch 32, so that current flows into each pair of the first coil 25 and the second coil 26, the two contact regions 23 approach each other, and then the plug 100 moves away from the second switch 32 under the action of the buffer assembly 4, so that the pin 101 is disengaged from the second switch 32; when subjected to an external force, the plug 100 can move downwards against the action of the damping member 4 to again trigger the second switch 32, so that a current flows in each pair of the first coil 25 and the second coil 26, and the two contact regions 23 move away from each other.

In a particular implementation, the cushioning assembly 4 comprises a plurality of elastic elements 41 distributed uniformly between the plug 100 and the casing 1, such as: a spring.

As shown in fig. 6, in another specific implementation manner, in order to ensure that the movement direction is more reliable in the process of inserting the plug pin 101 into the jack, the buffer assembly 4 further includes a limiting frame 42 disposed at the top of the housing 1 and a floating plate 43 slidably disposed in the limiting frame 42, a through hole corresponding to the jack is formed in the floating plate 43, and the elastic member 41 is disposed between the floating plate 43 and the housing 1.

Further, in order to prevent the floating plate 43 from being separated from the limiting frame 42, a limiting portion for limiting the floating plate 43 is formed at the top end of the limiting frame 42, and specifically, the limiting portion may be a folded edge.

It should be noted that, the socket mentioned in this embodiment may be a fixed socket or a movable socket, and the specific form of the socket is not limited.

The following explains the working principle of the socket provided in this embodiment by taking a process of inserting and pulling one plug pin 101 of the plug 100 into and out of the corresponding contact 2 on the socket as an example:

before the plug pin 101 is inserted into the contact element 2, the first switch 31 is contacted, the first switch 31 is activated, and the corresponding first coil 25 and the second coil 26 are energized with currents in the same direction and repel each other, so that the first elastic arm 21 and the second elastic arm 22 are driven to be away from each other, and the gap is expanded, so that the process of inserting the plug pin 101 into the contact element 2 is more labor-saving; after the plug pin 101 is inserted in place on the socket, the bottom of the plug pin 101 contacts the second switch 32 to activate the second switch 32, the direction of the current in the first coil 25 is opposite to the direction of the current in the second coil 26, and the first coil 25 and the second coil 26 attract each other, so that the first elastic arm 21 and the second elastic arm 22 are driven to approach each other, the gap is reduced, and the reliable connection between the plug pin 101 and the contact 2 is ensured. After the plug pin 101 touches the second switch 32, it can be disengaged from the second switch 32 under the action of the buffer assembly 4.

When the plug needs to be pulled out, the plug is pressed towards the direction of the socket, the plug pin 101 touches the second switch 32 again, currents in the same direction are introduced into the first coil 25 and the second coil 26, the first coil 25 and the second coil 26 repel each other, and therefore the first elastic arm 21 and the second elastic arm 22 are driven to be away from each other, gaps are enlarged, and the plug pin 101 is convenient to pull out. At the same time, the buffer member 4 can apply a force to the plug 100 in a direction away from the socket, so that the pin 101 can be more easily disengaged from the contact 2. When the pin 101 is disengaged from the socket, the first switch 31 is reset and the current in both the first coil 25 and the second coil 26 is cut off.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
