[0028] An embodiment of the first aspect of this application provides a plug for insertion into a socket so that current from the socket can be conducted to an electrical device, wherein the plug may be a grounded plug, a polarized plug, etc.
[0029] Please refer to Figures 1 to 3 The plug 100 includes a plug body 10, a braided tail 20, at least two first connecting structures 14, and at least one second connecting structure 24. The plug body 10 includes a first inclined surface 11 located at one end of the plug body 10 along the insertion direction X of the plug 100; the plug body 10 has a first threading hole 12, one end of which is located on the first inclined surface 11. The braided tail 20 includes a second inclined surface 211 disposed opposite to the first inclined surface 11; the braided tail 20 has a second threading hole 22 communicating with the first threading hole 12, one end of which is located on the second inclined surface 211.
[0030] Each of the first connecting structures 14 is arranged circumferentially along one end of the first through hole 12 located on the first inclined surface 11; or,
[0031] Each of the first connecting structures 14 is arranged circumferentially along one end of the second threading hole 22 on the second inclined surface 211.
[0032] The second connecting structure 24 is detachably connected to any of the first connecting structures 14; one of the first connecting structure 14 and the second connecting structure 24 is provided on the plug body 10 and the other is provided on the wire mesh tail 20, so as to change the relative position of the wire mesh tail 20 and the plug body 10.
[0033] The plug body 10 includes prongs 13 and a support structure for mounting the prongs 13, which can be inserted into the socket and electrically connected to the socket.
[0034] The insertion direction X of plug 100 refers to the length direction of pin 13. The first inclined surface 11 is located at one end of plug body 10 along the insertion direction X of plug 100, meaning that on the insertion direction X of plug 100, the first inclined surface 11 is located at the end of plug body 10 away from pin 13. The first inclined surface 11 is a plane with an angle A greater than 0° and less than 90° with the insertion direction X of plug 100.
[0035] One end of the first wire hole 12 is located on the first inclined surface 11, meaning that one opening of the first wire hole 12 is located on the first inclined surface 11; the other end of the first wire hole 12 is connected to the space inside the plug body 10 that accommodates the pin 13. The first wire hole 12 is used for the power cord to pass through, so that the power cord outside the plug body 10 can pass through the first wire hole 12 and be electrically connected to the pin 13.
[0036] The wire mesh 20 is located on the side of the plug body 10 away from the pin 13 along the insertion direction X. The wire mesh 20 is used to cover the power cord and improve the bending performance at the connection between the plug 100 and the power cord. The wire mesh 20 is also called a wire stop or wire tail.
[0037] The second inclined surface 211 is positioned opposite the first inclined surface 11, meaning that the second inclined surface 211 is in contact with the first inclined surface 11. The second inclined surface 211 is located at the end of the mesh tail 20 along its length Y direction, close to the first inclined surface 11. The second inclined surface 211 is a plane with an angle B greater than 0° and less than 90° with the length Y direction of the mesh tail 20. Optionally, the angle B between the second inclined surface 211 and the length Y direction of the mesh tail 20 is equal to the angle A between the first inclined surface 11 and the insertion direction X of the plug 100, so that the length Y direction of the mesh tail 20 can be consistent with the insertion direction X of the plug 100, and the space occupied by the plug 100 in the height direction is smaller when the plug 100 is connected to the socket on the wall.
[0038] The second wire-passing hole 22 passes through the mesh tail 20 and is used for the power cord to pass through the mesh tail 20, so that the mesh tail 20 covers the power cord. The second wire-passing hole 22 is connected to the first wire-passing hole 12, that is, the opening of the second wire-passing hole 22 and the opening of the first wire-passing hole 12 at least partially overlap, and the power cord can pass through the second wire-passing hole 22 and the first wire-passing hole 12 in sequence to connect to the plug 13. One end of the second wire-passing hole 22 is located on the second inclined surface 211, that is, one opening of the second wire-passing hole 22 is located on the second inclined surface 211.
[0039] The second connecting structure 24 is detachably connected to any of the first connecting structures 14. That is, the second connecting structure 24 can be connected to one of the first connecting structures 14, and can be detached from the connected first connecting structure 14 before being connected to other first connecting structures 14. The positions of the different first connecting structures 14 vary, and the overall relative position of the second connecting structure 24 with all the first connecting structures 14 changes when the second connecting structure 24 is connected to different first connecting structures 14. Optionally, the first connecting structure 14 can be a male-end snap-fit, a female-end snap-fit, a protrusion, or a groove, etc. Optionally, the second connecting structure 24 can be a male-end snap-fit, a female-end snap-fit, a protrusion, or a groove, etc.
[0040] For example, the first connecting structure 14 is a male end snap fastener, and the second connecting structure 24 is a female end snap fastener.
[0041] For example, the first connecting structure 14 is a female end snap fastener, and the second connecting structure 24 is a male end snap fastener.
[0042] Each of the first connecting structures 14 is arranged circumferentially along the first threading hole 12 at one end of the first inclined surface 11, or each of the first connecting structures 14 is arranged circumferentially along the second threading hole 22 at one end of the second inclined surface 211. One of the first connecting structures 14 and the second connecting structure 24 is located on the plug body 10, and the other is located on the wire mesh tail 20. This means that the positions of the first connecting structure 14 and the second connecting structure 24 are different.
[0043] When the first connecting structure 14 is provided on the plug body 10, the second connecting structure 24 is provided on the wire mesh tail 20. Each of the first connecting structures 14 is arranged circumferentially along one end of the first wire hole 12 located on the first inclined surface 11. The first wire hole 12 located on the first inclined surface 11 refers to the opening of the first wire hole 12 on the first inclined surface 11. The second connecting structure 24 is connected to different first connecting structures 14, which can change the circumferential position of the second connecting structure 24 at the opening of the first wire hole 12, that is, can change the position of the wire mesh tail 20 relative to the plug body 10, so that the wire mesh tail 20 moves relative to the plug body 10, changing the angle between the length direction of the wire mesh tail 20 and the insertion direction X of the plug 100, so that the plug 100 can be converted between a straight plug and a bent plug. When the plug 100 is a straight plug, it occupies less space in the height direction, and is suitable for spaces with a small height around the socket. When the plug 100 is a bent plug, it occupies less space in the direction perpendicular to the wall, and is suitable for spaces with a small size in the direction perpendicular to the wall around the socket. The first connecting structure 14 and the plug body 10 can be an integral structure or separate structures. The second connecting structure 24 and the tail 20 can be an integral structure or separate structures.
[0044] When the first connecting structure 14 is located on the tail 20, the second connecting structure 24 is located on the plug body 10. Each of the first connecting structures 14 is arranged circumferentially along one end of the second through hole 22 located on the second inclined surface 211. The end of the second through hole 22 located on the second inclined surface 211 refers to the opening of the second through hole 22 on the second inclined surface 211. The second connecting structure 24 is connected to different first connecting structures 14, which can change the circumferential position of the second connecting structure 24 at the opening of the second through hole 22, that is, can change the position of the plug body 10 relative to the tail 20, so that the plug body 10 can move relative to the tail 20, and can change the angle between the length direction of the tail 20 and the insertion direction X of the plug 100, so that the plug 100 can be converted between a straight plug and a bent plug. When the plug 100 is a straight plug, it occupies less space in the height direction, and is suitable for spaces with a small height around the socket. When the plug 100 is a bent plug, it occupies less space in the direction perpendicular to the wall, and is suitable for spaces with a small size in the direction perpendicular to the wall around the socket. The first connecting structure 14 and the tail 20 can be an integral or separate structure. The second connecting structure 24 and the plug body 10 can be an integral or separate structure.
[0045] In use, the second connection structure 24 is connected to one of the first connection structures 14. Please refer to [reference needed]. Figure 1 In the initial state, the plug body 10 is connected to the wire mesh 20 to form a straight plug. The length direction Y of the wire mesh 20 is the same as or approximately the same as the insertion direction X of the plug 100. The plug 100 has the largest size in the insertion direction X. When the plug 100 is connected to the socket on the wall, the space occupied by the plug 100 in the height direction is small, which is suitable for spaces with small height around the socket.
[0046] For example, the first connecting structure 14 is located on the plug body 10, and the second connecting structure 24 is located on the wire mesh 20. When the space around the socket is smaller in the direction perpendicular to the wall than the size of the plug 100 in the insertion direction X, and the space around the socket is larger in the height direction, the plug 100 cannot be inserted into the socket. The second connecting structure 24 is removed from the current first connecting structure 14, the wire mesh 20 is separated from the plug body 10, and then the second connecting structure 24 is connected to other first connecting structures 14. The position of the second connecting structure 24 in the circumferential direction of the first wire hole 12 is changed. Please refer to [reference needed]. Figure 4The second inclined plane 211 moves relative to the first wire hole 12 on the first inclined plane 11, and the plug body 10 moves relative to the wire mesh tail 20. The angle between the length direction of the wire mesh tail 20 and the insertion direction X of the plug 100 changes, and the plug 100 is converted into a right-angle plug. The size of the wire mesh tail 20 in the insertion direction X of the plug 100 becomes smaller, and the size of the wire mesh tail 20 in the insertion direction X perpendicular to the plug becomes larger. The size of the plug 100 in the insertion direction X becomes smaller, so that the plug 100 can be inserted into the socket. In this case, the user does not need to buy a special power connector plug 100 cable, which is more convenient to use.
[0047] The beneficial effects of this application embodiment are as follows: the second connection structure 24 is connected to different first connection structures 14 to change the relative position of the tail 20 and the plug body 10, so that the plug 100 can be converted between a straight plug and a bent plug. When the plug 100 is a straight plug, it occupies less space in the height direction and is suitable for spaces with a small height around the socket. When the plug 100 is a bent plug, it occupies less space in the direction perpendicular to the wall, thus solving the technical problem that straight plugs are not suitable for spaces with a small size in the direction perpendicular to the wall around the socket.
[0048] In some embodiments, please refer to Figures 1 to 4 The angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is equal to the angle B between the second inclined surface 211 and the length direction Y of the tail 20. In other words, when the tail 20 and the plug body 10 form a straight plug, the length direction Y of the tail 20 is consistent with the insertion direction of the plug 100.
[0049] Optionally, the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is 45°, and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 is 45°. When the tail 20 and the plug body 10 form a bent plug, the length direction Y of the tail 20 is perpendicular to the insertion direction X of the plug 100.
[0050] Optionally, the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 can also be 40°, and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 can also be 40°. Optionally, the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 can also be 50°, and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 can also be 50°.
[0051] The beneficial effects of this application embodiment are as follows: when the included angle A and included angle B are equal, when the wire mesh tail 20 and the plug body 10 form a straight plug, the length direction Y of the wire mesh tail 20 is consistent with the insertion direction X of the plug 100. When the plug 100 is connected to the socket on the wall, the size of the plug 100 in the height direction is smaller, which is suitable for spaces with a small height around the socket.
[0052] In some embodiments, please refer to Figures 1 to 4 The angle A between the first inclined plane 11 and the insertion direction X of the plug 100 is less than or equal to 45°, and the angle B between the second inclined plane 211 and the length direction Y of the tail 20 is less than or equal to 45°. That is to say, the sum of the angles A and B is equal to or less than 90°.
[0053] When the angle A between the first inclined plane 11 and the insertion direction X of the plug 100 is 45°, and the angle B between the second inclined plane 211 and the length direction Y of the tail 20 is 45°, the sum of the angles A and B is 90°. When the tail 20 and the plug body 10 form a bent plug, the length direction Y of the tail 20 is perpendicular to the insertion direction X of the plug 100, and the plug 100 is smaller in size in the insertion direction X.
[0054] When the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is less than 45°, and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 is less than or equal to 45°, the sum of the angles A and B is less than 90°. When the tail 20 and the plug body 10 form a bent plug, the angle between the length direction Y of the tail 20 and the insertion direction X of the plug 100 is an acute angle, and the plug 100 is smaller in size in the insertion direction X.
[0055] When the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is less than or equal to 45°, and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 is less than 45°, the sum of the angles A and B is less than 90°. When the tail 20 and the plug body 10 form a bent plug, the angle between the length direction Y of the tail 20 and the insertion direction X of the plug 100 is an acute angle, and the plug 100 is smaller in size in the insertion direction X.
[0056] The beneficial effects of this application embodiment are as follows: limiting the included angles A and B to the above range, so that the sum of included angles A and B is equal to or less than 90°, when the wire mesh tail 20 and the plug body 10 form a bent plug, the included angle between the length direction Y of the wire mesh tail 20 and the insertion direction X of the plug 100 is a right angle or an acute angle, the plug 100 is smaller in size in the insertion direction X, and when the plug 100 is connected to the socket on the wall, the plug 100 is smaller in size in the direction perpendicular to the wall, which is more suitable for spaces around the socket that are smaller in size in the direction perpendicular to the wall.
[0057] In some embodiments, please refer to Figures 1 to 4The angle A between the first inclined plane 11 and the insertion direction X of the plug 100 is equal to the angle B between the second inclined plane 211 and the length direction Y of the tail 20. The angle A between the first inclined plane 11 and the insertion direction X of the plug 100 is less than or equal to 45°, and the angle B between the second inclined plane 211 and the length direction Y of the tail 20 is less than or equal to 45°.
[0058] The beneficial effects of this application's embodiments are as follows: When included angles A and B are equal, and the wire mesh tail 20 and the plug body 10 form a straight plug, the length direction Y of the wire mesh tail 20 is consistent with the insertion direction X of the plug 100. When the plug 100 is connected to a socket on the wall, the plug 100 has a smaller dimension in the height direction. By limiting included angles A and B to the above range, such that the sum of included angles A and B is equal to or less than 90°, when the wire mesh tail 20 and the plug body 10 form a bent plug, the angle between the length direction Y of the wire mesh tail 20 and the insertion direction X of the plug 100 is a right angle or an acute angle. The plug 100 has a smaller dimension in the insertion direction X, and when the plug 100 is connected to a socket on the wall, the plug 100 has a smaller dimension in the direction perpendicular to the wall. The plug 100 is suitable for spaces with low height around the socket, and also for spaces with low dimensions in the direction perpendicular to the wall around the socket.
[0059] In some embodiments, please refer to Figure 2 and Figure 3 The angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is 40°-50°, and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 is 40°-50°.
[0060] The inclination angles of the first inclined surface 11 and the second inclined surface 211 are limited so that the size of the tail 20 in the insertion direction X of the plug 100 is smaller after the tail 20 rotates relative to the plug body 10.
[0061] Optionally, the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is the same as the angle B between the second inclined surface 211 and the length direction Y of the tail 20.
[0062] For example, the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 is 45°. Compared with other inclination angles of the first inclined surface 11, after the mesh tail 20 rotates relative to the plug body 10, the size of the mesh tail 20 in the insertion direction X of the plug 100 is smaller, making it suitable for spaces with smaller dimensions in the direction perpendicular to the wall around the socket. At the same time, the angle B between the second inclined surface 211 and the length direction Y of the mesh tail 20 is 45°. Since the first inclined surface 11 and the second inclined surface 211 are in contact when the mesh tail 20 is connected to the plug body 10, when the mesh tail 20 and the plug body 10 form a straight plug, the length direction Y of the mesh tail 20 is consistent with the insertion direction X of the plug 100; when the mesh tail 20 and the plug body 10 form a bent plug, the length direction Y of the mesh tail 20 is perpendicular to the insertion direction X of the plug 100.
[0063] Optionally, the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 can both be 40°, or the angle A between the first inclined surface 11 and the insertion direction X of the plug 100 and the angle B between the second inclined surface 211 and the length direction Y of the tail 20 can both be 50°.
[0064] Of course, the angle A between the first inclined plane 11 and the insertion direction X of the plug 100 and the angle B between the second inclined plane 211 and the length direction Y of the tail 20 can be different. For example, one is 40° and the other is 45° or 50°.
[0065] The beneficial effects of this application embodiment are that: by limiting the inclination angle of the first inclined surface 11 and the second inclined surface 211 to the above range, after the mesh tail 20 moves relative to the plug body 10, the size of the mesh tail 20 in the insertion direction X of the plug 100 is smaller, so that the size of the plug 100 in the insertion direction X is smaller, and the plug 100 is suitable for the space around the socket with a smaller size in the direction of the vertical wall.
[0066] In some embodiments, please refer to Figure 2 and Figure 3 The first connecting structure 14 is disposed on the plug body 10, and the second connecting structure 24 is disposed on the tail 20; wherein the two first connecting structures 14 are centrally symmetrical about the first center line 15, the first center line 15 is perpendicular to the first inclined plane 11 and passes through the first wire hole 12 and is located at one end of the first inclined plane 11; at least two second connecting structures 24 are provided, wherein the two second connecting structures 24 are centrally symmetrical about the second center line 25, the second center line 25 is perpendicular to the second inclined plane 211 and passes through the second wire hole 22 and is located at one end of the second inclined plane 211.
[0067] The first center line 15 is a defined virtual line. The two first connecting structures 14 are symmetrical about the first center line 15, meaning that after the plug body 10 rotates 180° about the first center line 15, the overall structure of the two first connecting structures 14 is identical. The first center line 15 passes through the first through hole 12 at one end of the first inclined surface 11, meaning that the first center line 15 passes through the opening of the first through hole 12 on the first inclined surface 11.
[0068] When the tail 20 is connected to the plug body 10, two second connecting structures 24 symmetrical about the second center line 25 are respectively connected to two first connecting structures 14 symmetrical about the first center line 15. The positions of the two second connecting structures 24 and the two first connecting structures 14 are the same, and the first center line 15 coincides with the second center line 25. The two second connecting structures 24 are symmetrical about the second center line 25, meaning that after the tail 20 is rotated 180° around the second center line 25, the overall structure of the two second connecting structures 24 is the same. After the tail 20 is rotated 180° relative to the plug body 10, the two second connecting structures 24 can still be connected to the two first connecting structures 14.
[0069] The second center line 25 passes through the second wire hole 22 at one end of the second inclined surface 211. This means that the second center line 25 passes through the opening of the second wire hole 22 on the second inclined surface 211. When the tail of the net 20 is connected to the plug body 10, the second center line 25 passes through the opening of the first wire hole 12 on the first inclined surface 11, so that the first wire hole 12 and the second wire hole 22 are stably connected.
[0070] In use, the second connection structure 24 is connected to one of the first connection structures 14. In the initial state, the plug body 10 is connected to the tail 20 to form a straight plug.
[0071] When the space around the socket is smaller in the direction perpendicular to the wall than the maximum size of the plug 100 in the insertion direction X, and the space around the socket is larger in the height direction, the two second connecting structures 24 are detached from the two first connecting structures 14, the tail 20 is separated from the plug body 10, the second connecting structure 24 is rotated 180° about the second center line 25, and then the two second connecting structures 24 are connected to the two first connecting structures 14. This is equivalent to the second connecting structure 24 being rotated 180° about the first center line 15, which is equivalent to the tail 20 being rotated 180° about the first center line 15 on the plug body 10. The size of the plug 100 in the insertion direction X becomes smaller, so that the plug 100 can be used in the space around the socket where the size in the direction perpendicular to the wall is smaller.
[0072] The beneficial effects of this embodiment are as follows: The two second connecting structures 24 are connected to the two first connecting structures 14, making the connection between the mesh tail 20 and the plug body 10 more secure. The two first connecting structures 14 and the two second connecting structures 24 are symmetrical about the center of the first center line 15 and the center line 25, which means that the mesh tail 20 can rotate 180° on the plug body 10. Compared with the mesh tail 20 moving to other positions relative to the plug body 10, the mesh tail 20 is smaller in size in the insertion direction X of the plug 100, making the plug 100 more suitable for spaces with smaller dimensions in the direction perpendicular to the wall around the socket.
[0073] In some embodiments, please refer to Figure 2 and Figure 3 The first center line 15 passes through the first thread hole 12 and is located at the center of one end of the first inclined surface 11, and the second center line 25 passes through the second thread hole 22 and is located at the center of one end of the second inclined surface 211.
[0074] When the wire mesh 20 is connected to the plug body 10, the first center line 15 and the second center line 25 coincide. The center of the first wire hole 12 located at one end of the first inclined surface 11 is opposite to the center of the second wire hole 22 located at one end of the second inclined surface 211, and the overlapping area of the first wire hole 12 and the second wire hole 22 is relatively large. Optionally, the opening shapes of the first wire hole 12 located at one end of the first inclined surface 11 and the second wire hole 22 located at one end of the second inclined surface 211 are the same, and the openings of the first wire hole 12 and the second wire hole 22 coincide.
[0075] The beneficial effect of this application embodiment is that when the wire mesh 20 is connected to the plug body 10, the overlapping area of the first wire hole 12 and the second wire hole 22 is large, which can accommodate a thicker power cord and prevent the wall of the first wire hole 12 and the wall of the second wire hole 22 from squeezing the power cord.
[0076] In some embodiments, please refer to Figure 2 and Figure 3 The first connecting structure 14 is a limiting protrusion, and the second connecting structure 24 is a limiting groove, which engages with the limiting protrusion.
[0077] Optionally, the limiting protrusion and limiting groove can be provided on the first inclined surface 11 and the second inclined surface 211. Optionally, the limiting protrusion or limiting groove can also be provided on the plug body 10 on the side of the first inclined surface 11 perpendicular to the insertion direction X of the plug 100. Optionally, the limiting protrusion or limiting groove can also be provided on the tail 20 on the side of the second inclined surface 211 perpendicular to the length direction Y of the tail 20.
[0078] A limiting groove can be directly made on the tail 20 or the plug body 10. The tail 20 or the plug body 10 can also be connected to other structures, and a limiting groove can be made on the other structures.
[0079] Optionally, the components containing the limiting protrusion and the limiting groove can be made of rubber, plastic, or the like.
[0080] The beneficial effects of this application embodiment are as follows: the limiting protrusion and the limiting groove are engaged, and the limiting protrusion and the limiting groove can be connected or disengaged by plugging and unplugging, which facilitates the connection of the limiting groove with different limiting protrusions.
[0081] In some embodiments, please refer to Figure 2 and Figure 3 The tail of the net 20 includes a tail body 21 and a boss 23 on the tail body 21. A second inclined surface 211 is provided on one end face of the tail body 21. The boss 23 and the second inclined surface 211 form a limiting groove.
[0082] Optionally, the boss 23 and the tail body 21 can be an integral structure, which can improve the manufacturing efficiency of the tail 20. Optionally, the boss 23 and the tail body 21 can also be separate structures, which makes the forming of the boss 23 and the tail body 21 easier.
[0083] The second inclined surface 211 is located at one end of the tail body 21 along its length direction Y. The boss 23 and the second inclined surface 211 form a limiting groove, that is, part of the boss 23 is spaced apart from the second inclined surface 211. The limiting groove is located on the tail body 21, and the limiting protrusion is located on the plug body 10. The beneficial effect of this embodiment is that by using the second inclined surface 211 and the boss 23 to form a limiting groove, it is convenient to integrally injection mold the structure of the second inclined surface 211 and the limiting groove, which can improve the manufacturing efficiency of the tail 20.
[0084] In other embodiments, the tail of the net 20 includes a tail body 21 and a boss 23 disposed on the tail body 21, the boss 23 being recessed to form a limiting groove.
[0085] In some embodiments, please refer to Figure 2 and Figure 3 The limiting protrusion is flush with the first inclined surface 11, meaning that the limiting protrusion is located on the edge of the first inclined surface 11 on the plug body 10, and the limiting protrusion has a surface flush with the first inclined surface 11. Optionally, the limiting protrusion and the plug body 10 can be an integral structure, which can improve the manufacturing efficiency of the plug body 10. Optionally, the limiting protrusion and the plug body 10 can also be separate structures, which can reduce the molding difficulty of the limiting protrusion and the plug body 10.
[0086] The beneficial effects of this application embodiment are that: the limiting protrusion is flush with the first inclined surface 11, which facilitates the integral injection molding of the limiting protrusion and the first inclined surface 11, and can improve the manufacturing efficiency of the plug body 10.
[0087] In some embodiments, please refer to Figure 2 and Figure 3 The tail of the net 20 includes a tail body 21 and a boss 23 on the tail body 21. A second inclined surface 211 is provided on one end face of the tail body 21. The boss 23 and the second inclined surface 211 form a limiting groove. The limiting protrusion is flush with the first inclined surface 11.
[0088] The limiting protrusion is flush with the first inclined surface 11, meaning the limiting protrusion is located on the side of the first inclined surface 11 perpendicular to the insertion direction X of the plug 100. When the limiting groove is connected to the limiting protrusion, both the limiting groove and the boss 23 are located on the side of the first inclined surface 11 perpendicular to the insertion direction X of the plug 100.
[0089] With the two limiting protrusions symmetrical about the first center line 15 and the two limiting grooves symmetrical about the second center line 25, the two limiting protrusions are respectively located on both sides of the first inclined surface 11 along the insertion direction X perpendicular to the plug 100, and the two bosses 23 are respectively located on both sides of the first inclined surface 11 along the insertion direction X perpendicular to the plug 100. The plug body 10 is sandwiched between the two bosses 23, making the connection between the wire mesh tail 20 and the plug body 10 more stable. The openings of the two limiting grooves are arranged opposite each other.
[0090] In some embodiments, please refer to Figure 2 and Figure 3 Both the limiting protrusion and the limiting groove are strip-shaped. One of the limiting protrusion and the limiting groove extends along the inclined direction of the first inclined surface 11, and the other extends along the inclined direction of the second inclined surface 211.
[0091] The inclination direction of the first inclined surface 11 refers to the direction that is parallel to the first inclined surface 11 and whose angle with the insertion direction X of the plug 100 is equal to the angle A.
[0092] The inclination direction of the second inclined plane 211 refers to the direction that is parallel to the second inclined plane 211 and has an angle B between it and the length direction Y of the net tail 20.
[0093] When the limiting protrusions are provided on the plug body 10, two of the limiting protrusions extend along the inclined direction of the first inclined surface 11. Since the two limiting protrusions are arranged circumferentially at one end of the first wire hole 12 located on the first inclined surface 11, the two limiting protrusions are located on opposite sides of the first wire hole 12. The two limiting protrusions are symmetrically arranged about the first center line 15. When the limiting groove disengages from one of the limiting protrusions and connects with the other limiting protrusion, it is equivalent to the limiting groove rotating 180° about the first center line 15, which is equivalent to the tail of the mesh being able to rotate 180° about the first center line 15 on the plug body 10.
[0094] When the limiting protrusions are provided on the tail of the net 20, two of the limiting protrusions extend along the inclined direction of the second inclined surface 211. Since the two limiting protrusions are arranged circumferentially at one end of the second wire hole 22 located on the second inclined surface 211, the two limiting protrusions are located on opposite sides of the second wire hole 22. The two limiting protrusions are symmetrically arranged about the second center line 25. When the limiting groove disengages from one of the limiting protrusions and connects with the other limiting protrusion, it is equivalent to the limiting groove rotating 180° about the second center line 15 and the first center line 15. That is, it is equivalent to the plug body 10 being able to rotate 180° about the second center line 25 and the first center line 15 on the tail of the net 20.
[0095] The limiting protrusion and the limiting groove are set as strips extending along the inclined direction of the first inclined surface 11 and the second inclined surface 211. Since the inclined direction of the first inclined surface 11 and the second inclined surface 211 forms an angle with the insertion direction X of the plug 100, the limiting protrusion and the limiting groove form an angle with the insertion direction X of the plug 100.
[0096] The beneficial effects of this application embodiment are as follows: the length directions of the limiting protrusion and the limiting groove form an angle with the insertion direction X of the plug 100. When the plug 100 is pulled out of the socket, the length directions of the limiting groove and the limiting protrusion form an angle with the force direction of the plug 100, which can prevent the wire tail from separating from the plug body 10 when the user holds the wire tail to pull out the plug 100. The limiting protrusion is arranged in a centrally symmetrical manner. When the limiting groove is disengaged from one of the limiting protrusions and connected to the other limiting protrusion, it is equivalent to the wire tail 20 being able to rotate 180° relative to the first center line 15 on the plug body 10. Compared with the wire tail 20 moving to other positions relative to the plug body 10, the wire tail 20 is smaller in size in the insertion direction X of the plug 100, and the plug 100 is more suitable for spaces with smaller size in the direction perpendicular to the wall around the socket.
[0097] In some embodiments, please refer to Figures 1 to 3 The first inclined surface 11 abuts against the second inclined surface 211, that is, there is a force between the first inclined surface 11 and the second inclined surface 211. The first inclined surface 11 is subjected to the pressure of the second inclined surface 211, and the second inclined surface 211 is subjected to the pressure of the first inclined surface 11.
[0098] Optionally, the limiting protrusion is located on the plug body 10 and is flush with the first inclined surface 11; the tail 20 includes a tail body 21 and a protrusion 23 on the tail body 21, and a second inclined surface 211 is provided on one end face of the tail body 21. The protrusion 23 and the second inclined surface 211 form a limiting groove. A part of the protrusion 23 is spaced apart from and opposite to the second inclined surface 211. The side of the protrusion 23 opposite to the second inclined surface 211 abuts against the side of the limiting protrusion away from the second inclined surface 211 in a direction perpendicular to the first inclined surface 11. The protrusion 23 abuts the limiting protrusion and the second inclined surface 211 against the first inclined surface 11, so that the first inclined surface 11 and the second inclined surface 211 come into contact.
[0099] Optionally, the limiting protrusion is located on the plug body 10. In the direction perpendicular to the first inclined surface 11, the limiting protrusion is located on the side of the first inclined surface 11 away from the second inclined surface 211. The net tail includes a net tail body 21 and a boss 23 provided on the net tail body 21. The second inclined surface 211 is provided on one end face of the net tail body 21. In the direction perpendicular to the second inclined surface 211, the boss 23 is located on the side of the second inclined surface 211 close to the first inclined surface 11. The boss 23 is provided with a limiting groove. In the direction perpendicular to the first inclined surface 11, a portion of the boss 23 is located on the side of the limiting protrusion away from the first inclined surface 11, and this portion of the boss 23 abuts against the side of the limiting protrusion away from the first inclined surface 11. The boss 23 abuts the limiting protrusion towards the first inclined surface 11, so that the first inclined surface 11 and the second inclined surface 211 come into contact.
[0100] The beneficial effect of this application embodiment is that: the first inclined surface 11 and the second inclined surface 211 abut against each other, which can make the first inclined surface 11 and the second inclined surface 211 fit tightly together, preventing external dust, water and the like from entering the plug 100 from between the first inclined surface 11 and the second inclined surface 211.
[0101] In some embodiments, please refer to Figures 1 to 4 The plug 100 includes a plug body 10, a braided tail 20, two first connecting structures 14, and two second connecting structures 24. The plug body 10 includes a first inclined surface 11 located at one end of the plug body 10 along the insertion direction X of the plug 100, with an angle A of 45° between the first inclined surface 11 and the insertion direction X of the plug 100. The plug body 10 has a first threading hole 12, one end of which is located on the first inclined surface 11. The first connecting structures 14 are disposed on the plug body 10, and the second connecting structures 24 are disposed on the braided tail 20. The two first connecting structures 14 are centrally symmetrical about a first center line 15, which is perpendicular to the first inclined surface 11 and passes through the first threading hole 12, located at the center of one end of the first inclined surface 11.
[0102] The net tail 20 includes a second inclined surface 211 disposed opposite to the first inclined surface 11, and the angle B between the second inclined surface 211 and the length direction Y of the net tail 20 is 45°. The net tail 20 has a second threading hole 22 communicating with the first threading hole 12, and one end of the second threading hole 22 is located on the second inclined surface 211. A second connecting structure 24 is disposed on the net tail 20, and two second connecting structures 24 are centrally symmetrically arranged about a second center line 25. The second center line 25 is perpendicular to the second inclined surface 211 and passes through the second threading hole 22, located at the center of one end of the second inclined surface 211. The second connecting structure 24 is detachably connected to any of the first connecting structures 14.
[0103] Initially, please refer to Figure 1 The length direction Y of the tail 20 is consistent with the insertion direction X of the plug 100. The two first connecting structures 14 are connected to the two second connecting structures 24. The plug 100 has the largest size in the insertion direction X. When the plug 100 is connected to the socket on the wall, the space occupied by the plug 100 in the height direction is small, which is suitable for spaces with small height around the socket.
[0104] When the space around the socket is smaller in the direction perpendicular to the wall than the size of the plug 100 in the insertion direction X, and the space around the socket is larger in the height direction, the plug 100 cannot be inserted into the socket. Remove the second connecting structure 24 from the current first connecting structure 14, separate the tail 20 from the plug body 10, and then connect the second connecting structure 24 to the other first connecting structures 14. Please refer to [reference needed]. Figure 4 This is equivalent to the second connecting structure 24 rotating 180° about the first center line 15, which is equivalent to the tail of the net rotating 180° about the first center line 15 on the plug body 10. The length direction Y of the tail of the net is perpendicular to the insertion direction X of the plug 100, and the plug 100 becomes a bent plug. The size of the plug 100 in the insertion direction X becomes smaller, so that the plug 100 can be inserted into the socket.
[0105] An embodiment of the second aspect of this application also provides a power connector, which includes a power cord and a plug 100 as described in the first aspect, wherein the power cord is electrically connected to the plug 100.
[0106] The power cord is electrically connected to the pin 13 inside the plug body 10, and the power cord extends from the inside of the plug body 10 through the first wire hole 12 and the second wire hole 22 to the outside of the plug 100.
[0107] The beneficial effects of this application embodiment are as follows: This application embodiment includes the plug 100 in the first aspect embodiment. When the space around the socket is small in the direction perpendicular to the wall, the power cord can be electrically connected to the socket. When the space around the socket is small in the direction of the wall height, the power cord can also be electrically connected to the socket. The power connector has all the advantages of the plug 100 in the first aspect embodiment.
[0108] An embodiment of the third aspect of this application also provides an electrical device, which includes a power connector as described in the second aspect.
[0109] Optional electrical appliances can be rice cookers, computers, washing machines, range hoods, power strips, chargers, etc.
[0110] The beneficial effects of the embodiments of this application are as follows: The embodiments of this application include a power connector implemented in the second aspect. When the space around the socket is small in the direction perpendicular to the wall, the electrical device can be electrically connected to the socket. When the space around the socket is small in the direction of the wall height, the electrical device can also be electrically connected to the socket.
