[0030] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.
[0031] Embodiment 1
[0032] As Figure 1 shown, this embodiment provides, according to the first aspect of the present application, a secondary electrical connection structure 100, which is applied to a socket including an isolation chamber 300 and a plug pin chamber 400. The plug pin chamber 400 is used for the plug 200 to be inserted, and the isolation chamber 300 is used to arrange the secondary electrical connection structure 100. The secondary electrical connection structure 100 includes a moving block 1, a movable part 2, an electrical connection assembly 4, and a second elastic member 5.
[0033] A part of the moving block 1 is located inside the plug pin bin 400, and another part is located inside the isolation bin 300. The moving block 1 includes a wedge-shaped surface 11. The moving block 1 is configured such that when the plug 200 is inserted into the plug pin bin 400, the plug 200 abuts against the wedge-shaped surface 11 to cause the moving block 1 to move towards the inside of the isolation bin 300. The movable member 2 is formed in an L shape. The movable member 2 includes a first part 21 and a second part 22 that are connected to each other, and a rotating shaft 23 provided at the connection between the first part 21 and the second part 22. One end of the first part 21 away from the rotating shaft 23 is connected to the moving block 1, and a bullet head assembly 3 is provided at one end of the second part 22 away from the rotating shaft 23. The bullet head assembly 3 includes a first elastic member 31 and an abutting head 32. Two ends of the first elastic member 31 are respectively connected to the second part 22 and the abutting head 32. The electrical connection assembly 4 includes a power input piece 41, a first electrical connection piece 42, a second electrical connection piece 43, and a static contact piece 44. The first electrical connection piece 42 is formed in a sheet-like structure and is used to abut against the abutting head 32. The first electrical connection piece 42 is connected to the power input piece 41, and the second electrical connection piece 43 is connected to the static contact piece 44. One end of the second elastic member 5 is connected to the first part 21, and the other end of the second elastic member 5 is used to be installed inside the isolation bin 300.
[0034] The secondary electrical connection structure 100 includes an electrical connection state and a disconnection state. In the disconnection state, the first elastic member 31 is in a compressed state, the abutting head 32 abuts against the connection point of the first electrical connection piece 42 and the power input piece 41, the second elastic member 5 is in an extended state, and the first electrical connection piece 42 and the second electrical connection piece 43 are separated from each other; in the electrical connection state, the first elastic member 31 is in an extended state, the abutting head 32 abuts against the position of the first electrical connection piece 42 between the power input piece 41 and the static contact piece 44, the second elastic member 5 is in a compressed state, and the first electrical connection piece 42 and the second electrical connection piece 43 are in contact with each other.
[0035] Through the above technical solution, in the disconnection state, that is, when the plug 200 is not inserted into the socket, the power input piece 41 and the static contact piece 44 are separated from each other. That is to say, the static contact piece 44 is not charged, and thus it can be made that the socket sleeve (corresponding to the plug 200 for the plug 200 to be inserted) electrically connected to the static contact piece 44 is not charged. In this way, it can be made to avoid the problems of electric leakage and electric shock caused by accidentally touching the socket sleeve inside the socket, which is beneficial to effectively improving the safety of the socket. In the electrical connection state, that is, when the plug 200 is inserted into the socket, the power input piece 41 and the static contact piece 44 are in contact with each other, so that the static contact piece 44 can be made charged, and thus it can be made that the socket sleeve electrically connected to the static contact piece 44 is charged, so that the socket can supply power to the outside normally, effectively ensuring the safety of the socket.
[0036] For the convenience of those skilled in the relevant art to understand, the working principle / working process of the above technical solution is described below.
[0037] When the plug 200 is inserted into the socket, the front end of the plug 200 will abut against the wedge-shaped surface 11 of the moving block 1. And as the plug 200 is inserted, the moving block 1 will be pushed under the insertion action of the plug 200, that is, it will move in the direction into the isolation chamber 300. The moving block 1 will drive the L-shaped movable member 2 to rotate counterclockwise (this counterclockwise direction refers to Figure 1 the counterclockwise direction on the paper surface of
[0038] ). The bullet component 3 provided on the second part 22 will rotate with the rotation of the movable member 2. And during the rotation of the bullet component 3, due to the elastic force of the first elastic member 31, it will push the abutting head 32 to move in the direction away from the movable member 2. Thus, the bullet component 3 can be used to push the first electrical connection piece 42 towards the second electrical connection piece 43 until they contact, so as to realize the electrical connection between the power input piece 41 and the static contact piece 44, and further enable the socket to supply power to the plug 200 normally.
[0039] In one embodiment of the present application, as Figure 1 shown, the moving block 1 of the present application can be formed into a strip structure. An installation through hole (not shown) for the moving block 1 to pass through is provided on the isolation chamber 300. A sealing silica gel 61 is provided in the installation through hole and the sealing silica gel 61 is sleeved outside the moving block 1.
[0040] In this way, setting the moving block 1 as a strip structure can facilitate the moving block 1 to move more stably and reliably towards the movable member 2 under the action of the plug 200 and can reliably push the movable member 2 to rotate. At the same time, the provided sealing silica gel 61 can reliably cover the moving block 1 to ensure the sealed environment of the isolation chamber 300, and further ensure the safety of the socket.
[0041] In the present application, there are various embodiments in which the moving block 1 pushes the movable member 2 to rotate. For example, in one embodiment, the moving block 1 can directly push the movable member 2 to rotate, that is, the end of the moving block 1 away from the plug 200 directly abuts against the movable member 2. In this way, this embodiment has the advantage of simple structure.
[0042] In another embodiment of the present application, as Figure 1As shown, the secondary electrical connection structure 100 of the present application may further include a connecting shaft 71 formed in a cylindrical shape. Moving through holes 72 through which the connecting shaft 71 passes are respectively formed on the moving block 1 and the first part 21. The moving through holes 72 are formed as oblong through holes extending along the length direction of the first part 21, so that the connecting shaft 71 can move along the length direction of the first part 21 within the moving through holes 72.
[0043] In this way, the movable connecting shaft 71 enables the moving block 1 and the movable member 2 to have a certain mechanical connection structure, ensuring the reliability of their relative positions. Thus, it can be ensured that after the moving block 1 and the movable member 2 are switched between the electrically connected state and the disconnected state multiple times, their relative positions and linkage reliability can still be guaranteed.
[0044] In this embodiment, the moving through holes 72 are set as oblong holes. In this way, during the movement of the moving block 1 and the rotation of the movable member 2, the connecting shaft 71 can move up and down within the oblong through holes, so that on the basis of ensuring their connection state, it can also ensure that the moving block 1 can push the movable member 2 to rotate to achieve the switching between the electrically connected state and the disconnected state.
[0045] In an embodiment of the present application, as Figure 1 shown, one end of the second part 22 of the present application far from the rotating shaft 23 is recessed inward to form a receiving cavity 221. The receiving cavity 221 is used to receive the bullet head assembly 3. The first elastic member 31 is disposed in the receiving cavity 221 and connected to the second part 22, and the abutting head 32 at least partially extends out of the receiving cavity 221.
[0046] In this way, the provided receiving cavity 221 not only facilitates the stable and reliable installation of the bullet head assembly 3, but also can form a certain limiting and guiding effect on the bullet head assembly 3, enabling the abutting head 32 to move reliably along the axial direction of the first elastic member 31. In addition, the receiving cavity 221 can form a limiting effect on the first elastic member 31, so that the elastic force direction of the first elastic member 31 is always along the length direction of the second part 22, in order to ensure that the abutting head 32 can always form an abutting state with the first electrical connection piece 42.
[0047] In an embodiment of the present application, as Figure 1 shown, the first electrical connection piece 42 of the present application can be formed as an arc-shaped sheet-like structure bent towards the movable member 2. The vertex of this arc-shaped sheet-like structure is connected to the power input piece 41. In the disconnected state, the abutting head 32 abuts against the vertex of this arc-shaped sheet-like structure.
[0048] In this way, the first electrical connection piece 42 can be formed into a seesaw-like structure. The power input piece 41 serves as the fulcrum of the first electrical connection piece 42. The first electrical connection piece 42 can rotate around the fulcrum and is limited by the power input piece 41. In this embodiment, the first electrical connection piece 42 can better fit the working process of the bullet head assembly 3, enabling the extension amount of the bullet head assembly 3 (i.e., the length by which the abutting head 32 protrudes from the second part 22) to be as small as possible, improving the matching degree between the two, and increasing the rotational response rate of the first electrical connection piece 42.
[0049] It can be understood that in this embodiment, the first electrical connection piece 42 can also be formed into a flat plate structure. The middle part of this flat plate structure is connected to the power input piece 41. In the disconnected state, the abutting head 32 abuts against the middle part of this flat plate structure.
[0050] In an embodiment of the present application, as Figure 1 shown, the abutting head 32 of the present application can include a cylindrical part 321 and a conical part 322 that are connected to each other. The large end of the conical part 322 is connected to the cylindrical part 321. The small end of the conical part 322 is used to abut against the first electrical connection piece 42. One end of the cylindrical part 321 away from the conical part 322 is connected to the first elastic member 31.
[0051] In this way, during the rotation of the bullet head assembly 3, the conical part 322 arranged in this way can abut against the first electrical connection piece 42 at any angle, enabling the first electrical connection piece 42 to contact the second electrical connection piece 43. In addition, the conical part 322 can effectively reduce the friction between the abutting head 32 and the first electrical connection piece 42, which is more conducive to the rotation of the abutting head 32 and its abutment against the first electrical connection piece 42.
[0052] In an embodiment of the present application, the first elastic member 31 and / or the second elastic member 5 of the present application can be set as springs. Springs have a long service life, excellent elastic properties, and low manufacturing costs.
[0053] It can be understood that the first elastic member 31 and / or the second elastic member 5 of the present application can also be set as other elastic structures or components, such as elastic sheets, plastic elastomers, silicone elastomers, etc. The present application does not make specific limitations on this.
[0054] In an embodiment of the present application, as Figure 1 shown, a receiving cavity 211 adapted to the second elastic member 5 can be formed on the first part 21 of the present application. One end of the second elastic member 5 extends into the receiving cavity 211 and is connected to the first part 21.
[0055] In this way, by opening such a receiving cavity 211 on the first part 21, it is not only convenient to install the second elastic member 5, but also helpful to guide the elastic force direction of the second elastic member 5 through the receiving cavity 211, so that the second elastic member 5 can more accurately and reliably push the movable member 2 to reset.
[0056] In one embodiment of the present application, Figure 1 As shown, the first connecting sheet 42 and / or the second connecting sheet 43 of the present application are set as silver contacts. Silver contacts have advantages such as good conductivity, long service life and small space occupation, and can be well adapted to the secondary connecting structure 100 of the present application.
[0057] According to the second aspect of the present application, a socket (not shown) is also provided, comprising the secondary electrical connection structure 100 of any one of the technical solutions in the first aspect of the present application.
[0058] In this way, when the socket provided by the present application is not in use, the socket sleeve corresponding to the plug 200 in the socket is not electrically charged, which can effectively improve the safety of the socket and help to avoid the risk of leakage and electric shock as much as possible.
[0059] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
