[0027] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this application; the described embodiments are merely a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes all and any combination of one or more of the associated listed items.

[0030] In the various embodiments of this application, for ease of description and not limitation, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, whether direct or indirect. Terms such as "upper," "lower," "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0031] Please see Figure 1 , Figure 2 as well as Figure 3This application provides a socket 100 for mating with a plug 200 to conduct electricity. In some embodiments, conductive pins 60 are provided on the socket 100, and mating pins 210 for electrical conduction are provided on the plug 200. In other embodiments, conductive pins 60 may be provided on the plug 200, and mating pins 210 for electrical conduction may be provided on the socket 100. In this embodiment, the example of pins 60 being provided in the socket 100 will be described.

[0032] Understandably, the number of pins 60 can be two or three.

[0033] The socket 100 includes a housing 10, a pin holder 20, a first elastic element 30, and a button assembly 40. The pin holder 20 is movably disposed in the housing 10 so that the pin 60 can pass through the pin holder 20; the first elastic element 30 elastically connects the housing 10 and the pin holder 20; the button assembly 40 elastically connects the housing 10 and limits the pin holder 20. When the socket 100 is not in use, the conductive pin 60 is hidden in the pin holder 20.

[0034] The outer casing 10 is hollow inside, serving to house the needle holder 20, the first elastic element 30, and the button assembly 40. Additionally, the outer casing 10 also serves a dustproof function. The shape of the outer casing 10 is not limited and can be configured as needed. In this embodiment, the outer casing 10 is approximately a cuboid.

[0035] The outer casing 10 is insulated, and the material of the outer casing 10 is selected from insulating materials.

[0036] The housing 10 has a connecting surface 12 inside. The needle holder 20 is movably connected to the connecting surface 12 via the first elastic member 30, that is, one end of the first elastic member 30 is connected to the connecting surface 12, and the other end is connected to the needle holder 20. The surface of the needle holder 20 facing the connecting surface 12 has a second through hole (not shown in the figure). One end of the needle 60 is connected to the connecting surface 12, and the other end can pass through the second through hole into the needle holder 20. The movement of the needle holder 20 can make the needle 60 hidden or exposed in the needle holder 20.

[0037] Please refer to the following: Figure 4The button assembly 40 includes a button post 42, a second elastic element 44, and a latch 46. The button post 42 is elastically connected to the connecting surface 12 via the second elastic element 44; the latch 46 is movably connected to the button post 42. Specifically, one end of the button post 42 facing away from the second elastic element 44 movably protrudes from the housing 10 to facilitate pressing the button post 42. A groove 422 and a connecting portion 424 passing through the groove 422 are provided on the side wall of the button post 42. One end of the latch 46 has a through hole 466 adapted to the connecting portion 424. The latch 46 passes through the through hole 466 into the connecting portion 424 and can rotate around the connecting portion 424. The groove 422 provides space for the rotation of the latch 46.

[0038] Please refer to it again. Figure 1 The needle holder 20 has a first retaining structure 24 and a second retaining structure 26 on its surface adjacent to the button assembly 40. The distance from the first retaining structure 24 to the connecting surface 12 is less than the distance from the second retaining structure 26 to the connecting surface 12. The latch 46 can cooperate with either the first retaining structure 24 or the second retaining structure 26 to limit the needle holder 20. The first retaining structure 24 or the second retaining structure 26 can be a hole, a slot, etc. In this embodiment, both the first retaining structure 24 and the second retaining structure 26 are holes.

[0039] Please refer to it again. Figure 4 The button assembly 40 further includes a third elastic element 48, which elastically connects the button post 42 and the latch 46. Specifically, the latch 46 includes a first end 462 and a second end 464. The first end 462 has the through hole 466 to allow the latch 46 to be movably disposed on the button post 42; the second end 464 is connected to the button post 42 through the third elastic element 48. When the latch 46 is not subjected to external force, the latch 46 is engaged in the first holding structure 24. At this time, the included angle between the latch 46 and the button post 42 is θ1 (see [reference]). Figure 5 When the buckle 46 is subjected to an external force, the buckle 46 rotates about the first end 462 as the center and the second end 464 toward the button post 42. At this time, the angle between the buckle 46 and the button post 42 is θ2 (see [reference]). Figure 6 ); then θ2 < θ1; when the buckle 46 loses the external force, the buckle 46 rotates with the first end 462 as the center and the second end 464 away from the button post 42 under the action of the elastic restoring force of the third elastic element 48.

[0040] The socket 100 also includes a chuck 50, which is housed in and fixed to the housing 10. The chuck 50 has a first through hole 52, through which the button assembly 40 passes. The shape of the first through hole 52 is not limited. When the third elastic member 48 is not deformed, the distance from the second end 464 of the latch 46 to the button post 42 in the same plane is L1 (see [reference]). Figure 4 The distance from the wall forming the first through hole 52 to the button post 42 is L2, satisfying L1 > L2.

[0041] During the movement of the button post 42, the chuck 50 acts to block the latch 46, allowing the latch 46 to open and close. Specifically, when the button post 42 is not subjected to external force, the button post 42 passes through the first through hole 52 into the chuck 50, and the latch 46 is not in contact with the chuck 50; when the button post 42 is subjected to external force, the latch 46 retracts due to the blocking force of the chuck 50, and together with the button post 42, passes through the first through hole 52 into the chuck 50; when the button post 42 loses the external force, the button post 42 returns to its initial position under the action of the second elastic member 44, and the latch 46 loses the blocking force of the chuck 50 and simultaneously returns to its initial position under the action of the third elastic member 48.

[0042] The first elastic element 30, the second elastic element 44 and the third elastic element 48 are all elastic, such as springs, or elastic elements made of elastic materials, such as polymer materials.

[0043] To more clearly illustrate the connection relationship between the components in this embodiment, the interaction process between the socket 100 and the plug 200 provided in this embodiment is described in detail below.

[0044] Please see Figure 5 In the initial state, the buckle 46 is engaged in the first holding structure 24, thereby fixing the needle seat 20 in the initial position. At this time, the first elastic element 30, the second elastic element 44 and the third elastic element 48 are all in the initial state, that is, the first elastic element 30, the second elastic element 44 and the third elastic element 48 have not undergone deformation.

[0045] Please see Figure 6When the socket 100 is needed, a force F is first applied to the button post 42 in the direction of the connecting surface 12. The second elastic element 44 is compressed and deformed. The button post 42 drives the latch 46 to move. The latch 46 retracts under the blocking action of the chuck 50. At this time, the third elastic element 48 is compressed and deformed, causing the latch 46 to gradually disengage until it is completely disengaged from the first holding structure 24. The pin seat 20 is released from the restriction of the latch 46. At this time, the pin seat 20 is only subjected to the elastic force of the first elastic element 30. Then, the plug 200 is inserted into the socket 100. When the pin seat 20 is subjected to the force F of the plug 200, the pin seat 20 moves towards the connecting surface 12. The first elastic element 30 deforms, and the pin 60 is fully exposed to the pin seat 20 and abuts against the pin 210 inside the plug 200 to achieve electrical connection between the plug 200 and the socket 100.

[0046] Please see Figure 7 The force F applied to the button post 42 is released, the second elastic member 44 recovers its deformation, and the button post 42 moves away from the connecting surface 12 under the action of the second elastic member 44. The latch 46 moves with the button post 42 and disengages from the chuck 50. The latch 46 returns to its initial position under the action of the third elastic member 48. At this time, the latch 46 is engaged in the second holding structure 26, thereby fixing the pin seat 20. This can prevent the pin seat 20 from having a tendency to move away from the connecting surface 12 due to the elastic force of the first elastic member 30, which would cause the connection between the socket 100 and the plug 200 to be unstable.

[0047] Please see Figure 8 If the plug 200 needs to be unplugged, a force F is first applied to the button post 42, then a force F is applied to the plug 200, and then the force F applied to the button post 42 is released. The needle seat 20 returns to its initial position under the action of the first elastic member 30. At the same time, the buckle 46 is engaged in the first holding structure 24, and the needle 60 is hidden in the needle seat 20.

[0048] Please see Figure 9 This is a schematic diagram of the structure of a socket 100a provided in another embodiment of this application. In this embodiment, a button assembly 40a is inserted through the pin seat 20, and a portion of the button post 42 protrudes from the outer shell 10. That is, the projection of the button assembly 40a on the connecting surface 12 is located within the projection area of ​​the pin seat 20 on the connecting surface 12. Other components adapted to the button assembly 40a are also adjusted accordingly.

[0049] Understandably, in this embodiment, the chuck 50 adapted to the button assembly 40a is located in the pin holder 20.

[0050] When the button assembly 40a is inserted into the pin holder 20, and the socket 100a is needed, a force F is applied to the plug 200. This force first acts on the button assembly 40a. After the button assembly 40a is completely released from the constraint of the first retaining structure 24, the pin holder 20 is released from the constraint of the latch 46. The force F is then applied to the plug 200 to electrically connect it to the socket 100a. If it is necessary to unplug the plug 200, a force F is applied to it to disconnect it from the socket 100a. In this embodiment, only a force is applied to the plug 200; no additional force is required on the button assembly 40a to achieve the connection and disconnection of the plug 200 and the socket 100a.

[0051] The sockets 100 and 100a provided in this application, by providing a movable pin holder 20, can be fixed by the fixing action of the button assembly 40 when the sockets 100 and 100a are not in use, so that the conductive pins 60 or leads 210 are hidden in the pin holder 20 to avoid exposure and thus improve safety; when the sockets 100 and 100a need to be used, the button assembly 40 is pressed and the fixing action of the button assembly 40 fixes the pin holder 20 after the plug 200 is inserted, so as to realize the electrical connection between the sockets 100 and 100a and the plug 200.

[0052] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
