[0033] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0035] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarities or connections between the objects. It should be understood that the directions "above," "below," "outside," and "inside" are intended to represent normal use. The directions "left" and "right" refer to the left-right directions shown in the corresponding schematic diagrams, which may or may not represent normal use.

[0036] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0037] In the related art, a socket assembly includes a housing, a movable cover, a trigger member, and a transmission mechanism. The trigger member has a movable first transmission part, and the movable cover has a movable second transmission part. The power terminals of the socket assembly are arranged in a first direction. When the first and second transmission parts are arranged along the first direction, the transmission mechanism contacts the first and second transmission parts respectively along the first direction, causing the first and second transmission parts to move in opposite directions. The transmission mechanism occupies a large amount of space in the first direction. When the first and second transmission parts are arranged in a second direction intersecting the first direction, the transmission mechanism contacts the first and second transmission parts respectively along the second direction, causing the first and second transmission parts to move in opposite directions. The transmission mechanism is offset from the power terminals in the second direction, and the space on one side of the power terminals is not utilized, resulting in wasted space in the socket assembly. The socket assembly is large in size, which limits its use in a narrow space and is inconvenient to use.

[0038] In view of this, the embodiment of the present application provides a socket assembly, please refer to Figures 3 to 8The socket assembly includes a housing 1, a movable cover 2, a trigger member 3 and a transmission mechanism 4. The housing 1 has at least two power terminals 11, and the arrangement direction of the at least two power terminals 11 is a first direction. The movable cover 2 is installed on the housing 1. The movable cover 2 has a first socket 22 corresponding to the power terminal 11 and a first transmission part 21 that moves along the axial direction of the first socket 22. The axial direction of the first socket 22 is arranged crosswise with the first direction. The trigger member 3 is at least partially located in the space enclosed by the movable cover 2 and the housing 1. The trigger member 3 is staggered with the power terminal 11. The trigger member 3 has a second transmission portion 31 that moves along the axial direction of the first socket 22. The first transmission portion 21 and the second transmission portion 31 are arranged in a second direction, and the second direction is arranged to intersect with the axial direction of the first socket 22 and the first direction respectively. The transmission mechanism 4 is installed on the housing 1, and the transmission mechanism 4 contacts the first transmission portion 21 and the second transmission portion 31 respectively so that the movement directions of the first transmission portion 21 and the second transmission portion 31 are opposite. When projected along the first direction, the projection area of the power terminal 11 at least partially overlaps with the projection area of the transmission mechanism 4.

[0039] Power terminals 11 are terminals that can serve as power interfaces for power supply. For alternating current (AC), at least one of the terminals 11 is the live terminal 11, and at least one of the terminals 11 is the neutral terminal 11. For direct current (DC), at least one of the terminals 11 is the positive terminal 11, and at least one of the terminals 11 is the negative terminal 11. Terminals for grounding or shielding wires used for protection are not considered power terminals 11.

[0040] Exemplarily, the socket assembly is applicable to a two-phase socket having only a live wire terminal 11 and a neutral wire terminal 11 , and is also applicable to a three-phase socket having a ground wire terminal.

[0041] Exemplarily, the dimension of the socket assembly along the axial direction of the first socket 22 is a thickness dimension.

[0042] For example, when the plug 5 is not inserted into the first insertion hole 22 , the surface of the movable cover 2 facing the plug 5 along the axial direction of the first insertion hole 22 is flush with the surface of the housing 1 facing the plug 5 along the axial direction of the first insertion hole 22 .

[0043] The plug 5 refers to the plug 5 used by the electrical device to obtain electricity, and the electrical device is connected to the socket assembly through the plug 5.

[0044] In the embodiment of the present application, the plug 5 passes through the first receptacle 22 and contacts the trigger member 3. The axial movement of the plug 5 along the first receptacle 22 pushes the trigger member 3 to move. The transmission mechanism 4 contacts the first transmission part 21 and the second transmission part 31 along the second direction, respectively, so that the movable cover 2 and the trigger member 3 move in opposite directions at the same time. During the movement of the trigger member 3 along the moving direction of the plug 5, the movable cover 2 moves in the opposite direction to the moving direction of the plug 5 under the drive of the transmission mechanism 4, so that the movable cover 2 protrudes from the surface of the shell 1. The plug 5 can be fully inserted into the movable cover 2 and the interior of the shell 1, ensuring the charging safety of the socket assembly and the plug 5. When the plug 5 is pulled out of the socket assembly, the movable cover 2 can return to its original position in the shell 1. The movable cover 2 protrudes from the surface of the shell 1 during the charging process of the plug 5. After charging is completed, the movable cover 2 retracts into the shell 1, reducing the axial size of the socket assembly along the first receptacle 22, making the socket assembly convenient to use. The first transmission portion 21 and the second transmission portion 31 are arranged along the second direction, and the transmission mechanism 4 contacts the first transmission portion 21 and the second transmission portion 31 respectively along the second direction. This reduces the space occupied by the transmission mechanism 4 in the first direction of the socket assembly, thereby improving the space utilization of the socket assembly and reducing the size of the socket assembly. When the first transmission portion 21 and the second transmission portion 31 are arranged along the second direction, the projection area of the power terminal 11 and the projection area of the transmission mechanism 4 projected along the first direction at least partially overlap. The transmission mechanism 4 is arranged in a portion of the space on one side of the power terminal 11 along the first direction. While the space occupied by the transmission mechanism 4 in the first direction is reduced, the space occupied by the transmission mechanism 4 in the second direction is minimized, further improving the space utilization of the socket assembly, reducing the size of the socket assembly in the second direction, and reducing the volume of the socket assembly, making the socket assembly easier to use and more portable.

[0045] For ease of explanation, as shown in the figure, the first direction is the direction indicated by arrow R1, the second direction is the direction indicated by arrow R2, and the axial direction of the first insertion hole 22 is the direction indicated by arrow R3.

[0046] In one embodiment, please refer to Figures 3 to 8 The transmission mechanism 4 includes a transmission shaft 41 and a transmission rod 42. The transmission shaft 41 is arranged on the housing 1, and the transmission rod 42 is arranged on the transmission shaft 41. The rotation center of the transmission rod 42 is parallel to the first direction. The first transmission part 21 and the second transmission part 31 are located on opposite sides of the transmission rod 42 along the second direction. The transmission rod 42 contacts the first transmission part 21 and the second transmission part 31 respectively so that the movement directions of the first transmission part 21 and the second transmission part 31 are opposite. Projected along the first direction, the projection area of the power terminal 11 at least partially overlaps with the projection area of the transmission rod 42.

[0047] The rotation center of the transmission rod 42 coincides with the central axis of the transmission shaft 41 .

[0048] In the embodiment of the present application, the transmission rod 42 is arranged on the transmission shaft 41, and the first transmission part 21 and the second transmission part 31 are located on opposite sides of the transmission shaft 41 along the second direction. The transmission mechanism 4 uses the lever principle to make the first transmission part 21 and the second transmission part 31 move in opposite directions. The structure of the transmission mechanism 4 is simple and reliable.

[0049] It is understood that the transmission mechanism 4 is not limited to the transmission rod 42. Exemplarily, the transmission mechanism 4 includes a connecting portion and a gear disposed on opposite sides along the second direction, the connecting portion having a rack meshing with the gear, the first transmission portion 21 and the second transmission portion 31 being respectively connected to the connecting portions on both sides, and the meshing of the gear and the rack causes the connecting portions on both sides to move in opposite directions.

[0050] In one embodiment, please refer to Figures 3 to 8 The transmission rod 42 has a first boss 421 on one side of the first transmission part 21 along the second direction, and the first boss 421 protrudes toward the movable cover 2. The first transmission part 21 has a first slide groove 211, and the first boss 421 is movably arranged in the first slide groove 211. The groove wall surface of the first slide groove 211 includes a first arc surface 212, a first plane 214 and a second arc surface 213. The first plane 214 connects the first arc surface 212 and the second arc surface 213. The first arc surface 212 and / or the second arc surface 213 are arranged at intervals from the first boss 421.

[0051] The first arc surface 212 and / or the second arc surface 213 are spaced apart from the first boss 421 so that the first sliding groove 211 has enough space for the first boss 421 to move.

[0052] In the embodiment of the present application, the first slide groove 211 has enough space for the first boss 421 to move. The first slide groove 211 can limit the moving range of the first boss 421 to prevent the first boss 421 from escaping from the first slide groove 211. The first boss 421 moves on the first arc surface 212, the first plane 214 and the second arc surface 213, so that the first boss 421 moves smoothly, thereby making the movable cover 2 move stably along the axial direction of the first socket 22.

[0053] It is understandable that the first transmission part 21 is not limited to being provided with the first sliding groove 211. Exemplarily, the first boss 421 contacts the first transmission part 21 along the axial direction of the first insertion hole 22, and when projected along the second direction, the projection area of the first boss 421 and the projection area of the first transmission part 21 do not overlap.

[0054] In one embodiment, please refer to Figures 3 to 8 The transmission rod 42 has a second boss 422 , the protruding direction of the second boss 422 intersects with the protruding direction of the first boss 421 , and the second boss 422 is located on a side of the first boss 421 away from the movable cover 2 along the axial direction of the first insertion hole 22 .

[0055] In the embodiment of the present application, the second boss 422 is arranged on the side of the first boss 421 away from the movable cover 2 along the axial direction of the first insertion hole 22. The second boss 422 strengthens the structure of the first boss 421 and reduces the deformation of the first boss 421 due to stress.

[0056] It is understandable that the transmission rod 42 may not be provided with the second boss 422 .

[0057] In one embodiment, please refer to Figures 3 to 8 The transmission rod 42 has a third boss 423 on one side toward the second transmission part 31 along the second direction, and the third boss 423 protrudes toward the trigger member 3. The second transmission part 31 has a second sliding groove 311. The third boss 423 is movably arranged in the second sliding groove 311. The groove wall surface of the second sliding groove 311 includes a third arc surface 312, a second plane 314 and a fourth arc surface 313. The second plane 314 connects the third arc surface 312 and the fourth arc surface 313. The third arc surface 312 and / or the fourth arc surface 313 are arranged at intervals from the third boss 423.

[0058] The third arc surface 312 and / or the fourth arc surface 313 are spaced apart from the third boss 423 so that the second sliding groove 311 has enough space for the third boss 423 to move.

[0059] In the embodiment of the present application, the second slide groove 311 has enough space for the third boss 423 to move. The second slide groove 311 can limit the movement range of the third boss 423 to prevent the third boss 423 from disengaging from the second slide groove 311. The third boss 423 moves on the third arc surface 312, the second plane 314 and the fourth arc surface 313, so that the third boss 423 moves smoothly, thereby making the trigger member 3 move stably along the axial direction of the first socket 22.

[0060] It is understandable that the second transmission portion 31 is not limited to being provided with the second sliding groove 311. For example, the third boss 423 contacts the second transmission portion 31 along the axial direction of the first insertion hole 22, and when projected along the second direction, the projection area of the third boss 423 does not overlap with the projection area of the second transmission portion 31.

[0061] In one embodiment, please refer to Figures 3 to 8 The transmission rod 42 has a fourth boss 424 , the protruding direction of the fourth boss 424 intersects with the protruding direction of the third boss 423 , and the fourth boss 424 is located on a side of the third boss 423 away from the movable cover 2 along the axial direction of the first insertion hole 22 .

[0062] In the embodiment of the present application, the fourth boss 424 is located on a side of the third boss 423 axially away from the movable cover 2 along the first insertion hole 22 . The fourth boss 424 strengthens the structure of the third boss 423 and reduces deformation of the third boss 423 under stress.

[0063] It is understandable that the transmission rod 42 may not be provided with the fourth boss 424 .

[0064] In one embodiment, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 9 The trigger member 3 has a guide groove 32, and the groove walls on opposite sides of the guide groove 32 along the first direction are stop parts 33. The plug 5 can move axially along the first socket 22 in the guide groove 32, and the stop part 33 limits the plug 5 from moving in the guide groove 32 along the first direction.

[0065] In an embodiment of the present application, a guide groove 32 and a stop portion 33 are provided on the trigger member 3. The stop portion limits the movement of the plug 5 along the first direction, and the guide groove 32 guides the movement direction of the plug 5 in the socket assembly. When the plug 5 is inserted into the socket assembly, the possibility of displacement between the plug 5 and the trigger member 3 along the first direction is reduced.

[0066] It is understandable that the stopper 33 and the guide groove 32 may not be provided on the trigger member 3. For example, the trigger member 3 has a contact portion along the axial direction of the first socket 22, and the plug 5 directly contacts the contact portion when inserted into the socket.

[0067] In one embodiment, please refer to Figure 9 The guide groove 32 has a guide surface 34 that contacts the plug 5. The guide surface 34 is located between the stop portions 33. The end of the guide surface 34 that is axially away from the movable cover 2 along the first socket 22 is the target end 35. The target end 35 is inclined toward the plug 5 along the second direction.

[0068] In the embodiment of the present application, the inclined guide surface 34 can guide the plug 5 to be smoothly inserted into the guide groove 32 of the trigger member 3. The plug 5 contacts the trigger member 3 in the guide groove 32 to drive the trigger member 3 to move together, thereby improving the accuracy of the position of the plug 5 in the socket assembly, reducing the displacement of the plug 5 during the insertion process, and facilitating the use of the socket assembly.

[0069] It is understood that the guide surface 34 is not limited to being an inclined surface. For example, the guide surface 34 is parallel to the axial direction of the first insertion hole 22.

[0070] In one embodiment, please refer to Figures 1 to 3 The housing 1 has a guide rib 12 , which extends along the axial direction of the first insertion hole 22 . The trigger member 3 is mounted on the guide rib 12 so that the trigger member 3 moves along the axial direction of the first insertion hole 22 .

[0071] In the embodiment of the present application, the trigger member 3 is installed on the guide rib 12 so that the trigger member 3 moves axially along the first plug hole 22, limiting the movement of the trigger member 3 along the first direction or the second direction, thereby improving the accuracy of the movement of the trigger member 3.

[0072] It is understandable that the housing 1 is not limited to being provided with the guide rib 12. Exemplarily, the trigger member 3 is in direct contact with the housing wall of the housing 1 along the second direction.

[0073] In one embodiment, please refer to Figure 3 The housing 1 has a protective terminal 13, which is located on one side of the power terminal 11 along the second direction. When projected along the first direction, the projection area of the transmission mechanism 4 spans the projection area of the power terminal 11 and the projection area of the protective terminal 13.

[0074] The protection terminal 13 is a grounding terminal.

[0075] In an embodiment of the present application, the shell 1 has a protective terminal 13, and the socket assembly is a three-phase socket. Projected along the first direction, the projection area of the transmission mechanism 4 spans the projection area of the power terminal 11 and the projection area of the protective terminal 13. The transmission mechanism 4 is arranged in the space on one side of the protective terminal 13 along the first direction, thereby further improving space utilization and reducing the volume of the socket assembly.

[0076] It is understood that, when projected along the first direction, the projection area of the transmission mechanism 4 spans the projection area of the power terminal 11 and the projection area of the protection terminal 13. For example, when projected along the first direction, the projection area of the power terminal 11 is outside the projection area of the transmission mechanism 4.

[0077] In one embodiment, please refer to Figure 3 , projected along the first direction, the projection area of the transmission rod 42 spans the projection area of the power terminal 11 and the projection area of the protection terminal 13.

[0078] In one embodiment, please refer to Figure 1 The movable cover 2 has a reset sleeve, and the socket assembly includes a column and an elastic member. The column is arranged on the shell 1, and the elastic member is sleeved on the column. The elastic member is at least partially located in the reset sleeve and abuts against the reset sleeve. The elastic member can enable the movable cover 2 to move away from the plug 5 along the axial direction of the first jack 22.

[0079] In one embodiment, the plug 5 is inserted into the first jack 22 and is interference-fitted with the power terminal 11 . The friction between the power terminal 11 and the plug 5 is greater than the elastic force of the elastic member on the movable cover 2 . When the power terminal 11 supplies power to the plug 5 , the elastic member will not cause the movable cover 2 to move.

[0080] In one embodiment, please refer to Figure 1 and Figure 8 The movable cover 2 has a protruding limiting portion 23, the protruding direction of the limiting portion 23 is arranged crosswise with the axial direction of the first insertion hole 22, and the limiting portion 23 abuts against the shell 1 to limit the movable cover 2 from moving out of the shell 1 along the axial direction of the first insertion hole 22.

[0081] In one embodiment, please refer to Figure 6 The trigger member 3 has a groove 315 , which is located on a side of the second sliding groove 311 away from the transmission rod 42 along the second direction. The groove 315 is used to avoid the fourth boss 424 .

[0082] In one embodiment, the guide surface 34 is an arc-shaped surface.

[0083] In one embodiment, the socket assembly includes a silicone anti-skid pad, which is arranged on a side of the housing 1 away from the movable cover 2 along the axial direction of the first insertion hole.

[0084] The socket assembly also includes a power cord and a power head connected to the power cord for connecting the socket assembly to electricity.

[0085] When the plug 5 is not inserted into the first receptacle 22, the socket assembly of the embodiment of the present application has an axial thickness of 17 mm along the first receptacle 22.
