Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] like Figure 1 As shown, touch devices (not shown in the figure) may include, but are not limited to, products such as tablet computers, electronic drawing tablets, learning machines, and game consoles.

[0022] The touch device includes a stylus 10 and a touch screen (not shown in the figure).

[0023] The stylus 10 has different working modes, including writing mode and erase mode.

[0024] When the tip of the stylus 10 touches the touch surface of the touchscreen, the stylus 10 enters writing mode. In writing mode, the stylus tip electrode of the stylus 10 transmits a downlink signal to the touchscreen, allowing the touchscreen to detect the writing position of the stylus 10 on the touchscreen and display the corresponding writing marks. Users can then use the stylus 10 to perform writing operations such as note-taking and drawing on the touchscreen. When the tail of the stylus 10 touches or approaches the touch surface of the touchscreen, the stylus 10 enters erasing mode. In erasing mode, the tail electrode of the stylus 10 transmits another downlink signal to the touchscreen, allowing the touchscreen to detect the erasing position of the stylus 10 on the touchscreen and delete the corresponding writing marks. Users can then use the stylus 10 to perform erasing operations such as note-taking and drawing on the touchscreen.

[0025] like Figures 1-4 As shown, the stylus 10 includes a battery module 100 and a pen body 200. The specific structures of the battery module 100 and the pen body 200 will be described in detail below.

[0026] The battery module 100 includes a housing 110 and a battery 120.

[0027] The shell 110 serves as a shell piece of the battery module 100. The specific material of the shell 110 is not limited here, and a designer can make a reasonable selection according to actual needs; for example, the material of the shell 110 can be, but is not limited to, plastic, silica gel, or rubber, etc.

[0028] The shell 110 has a containing cavity 110a, which is a hollow area inside the shell 110. The specific shape of the containing cavity 110a is not limited here, and a designer can make a reasonable design according to actual needs; for example, the shape of the containing cavity 110a can be adapted to the outer contour shape of the battery 120.

[0029] The battery 120 serves as a power supply of the battery module 100 for supplying power to the control assembly 220 of the pen body 200.

[0030] The battery 120 is arranged in the containing cavity 110a of the shell 110. The specific mounting manner between the battery 120 and the shell 110 is not limited here, and a designer can make a reasonable design according to actual needs; for example, a battery 120 mounting groove is arranged in the containing cavity 110a of the shell 110, and the battery 120 is inserted into the battery 120 mounting groove; for another example, a battery 120 mounting seat is arranged in the containing cavity 110a of the shell 110, and the battery 120 is mounted on the battery 120 mounting seat.

[0031] The shell 110 is used to be detachably connected with the pen body 200 of the stylus 10, so as to realize the detachable connection between the entire battery module 100 and the pen body 200 of the stylus 10, so as to facilitate the user to replace the battery module 100 with zero power or damaged, or the damaged pen body 200 in time. The specific detachable connection manner between the shell 110 and the pen body 200 of the stylus 10 is not limited here, and a designer can make a reasonable design according to actual needs; for example, the shell 110 and the pen body 200 (specifically the shell 210 of the pen body 200) of the stylus 10 can be detachably connected through a threaded connection; for another example, the shell 110 and the pen body 200 (specifically the shell 210 of the pen body 200) of the stylus 10 can also be detachably connected through a clamping connection; for another example, the shell 110 and the pen body 200 (specifically the shell 210 of the pen body 200) of the stylus 10 can also be detachably connected through a plug-in connection; for another example, the shell 110 and the pen body 200 (specifically the shell 210 of the pen body 200) of the stylus 10 can also be detachably connected through magnetic attraction.

[0032] When the housing 110 is assembled onto the outer shell 210 of the pen body 200, the battery 120 cooperates with the control component 220 of the pen body 200 to supply power to the control component 220; when the housing 110 is disassembled from the outer shell 210 of the pen body 200, the battery 120 stops supplying power to the control component 220. It should be noted that the battery 120 can supply power to the control component 220 of the pen body 200 via wired charging. For example, in this case, electrical conduction can be achieved between the battery 120 and the control component 220 of the pen body 200 through electrical contacts and electrodes. The battery 120 can also supply power to the control component 220 of the pen body 200 via wireless charging. For example, in this case, an electrical connection can be established between the battery 120 and the control component 220 of the pen body 200 through a wireless transmitting coil and a wireless receiving coil.

[0033] By designing the stylus 10 as two independent battery modules 100 and pen body 200, with the battery module 100 and pen body 200 being detachably connected, when the battery 120 is damaged, the user only needs to remove and replace the battery module 100, instead of discarding the entire stylus 10. This effectively reduces the user's operating costs. Similarly, when the pen body 200 is damaged, the user only needs to remove and replace the pen body 200, instead of discarding the entire stylus 10. This effectively reduces the user's operating costs.

[0034] The sidewalls at the tail end of the housing 110 and the outer shell 210 form an inner and outer nested structure. For example, the housing 110 may cover the sidewall at the tail end of the outer shell 210, in which case the housing 110 fits over the outer shell 210 of the pen body 200; another example is that the housing 110 may be covered by the sidewall at the tail end of the outer shell 210, in which case the outer shell 210 of the pen body 200 fits over the housing 110; yet another example is that the housing 110 may cover the sidewall at the tail end of the outer shell 210, and at the same time, the housing 110 may also be covered by the sidewall at the tail end of the outer shell 210, in which case the housing 110 and the outer shell 210 of the pen body 200 form a multi-layered inner and outer nested structure. It should be noted that "the shell 110 is covered by the side wall of the tail end of the outer shell 210" can mean that the entire shell 110 extends into the receiving cavity 110a of the outer shell 210, or that part of the shell 110 extends into the receiving cavity 110a of the outer shell 210, while the remaining part of the shell 110 extends out of the receiving cavity 110a of the outer shell 210.

[0035] like Figures 4-6 As shown, the housing 110 includes an end wall 111 and a peripheral side wall 112 surrounding the end wall 111. The end wall 111 and the peripheral side wall 112 are connected to form a receiving cavity 110a for accommodating the battery 120. The peripheral side wall 112 is arranged around the central axis of the stylus 10, and the end wall 111 is arranged along the direction of the central axis of the stylus 10.

[0036] When the shell 110 is engaged with the outer shell 210 of the pen body 200; the battery module 100 further comprises a clamping piece 130 connected with the peripheral side wall 112, the clamping piece 130 is used for clamping and matching with the clamping groove 210a on the side wall of the outer shell 210, so as to position the shell 110 in the outer shell 210 of the pen body 200, thereby realizing the installation between the battery module 100 and the pen body 200.

[0037] Wherein, the clamping piece 130 is a component for matching with the clamping groove 210a to realize the relative fixation of the position between the shell 110 and the outer shell 210 of the pen body 200; here, the specific connection mode between the clamping piece 130 and the peripheral side wall 112 is not limited, and the designer can reasonably design according to the actual needs; for example, the clamping piece 130 can be but not limited to at least one of the modes of screwing, clamping or inserting, and detachable connection with the peripheral side wall 112; for another example, the clamping piece 130 can also be but not limited to the mode of glueing, injection molding or 3D printing, and non-detachable connection with the peripheral side wall 112. It can be understood that the specific form of the clamping piece 130 can be many, and the specific connection mode between the clamping piece 130 and the peripheral side wall 112 is also not the same for different forms of the clamping piece 130; for example, the clamping piece 130 can include a clamping block (not shown in the figure), the clamping block is integrally formed with the peripheral side wall 112 by injection molding or 3D printing, at this time the clamping block is clamped with the clamping groove 210a to realize the relative fixation of the position between the shell 110 and the outer shell 210 of the pen body 200; for another example, the clamping piece 130 can also include a wedge-shaped block (not shown in the figure) and a spring (not shown in the figure), the peripheral side wall 112 is provided with a groove (not shown in the figure) corresponding to the clamping groove 210a of the outer shell 210, the wedge-shaped block is slidingly connected with the groove, and the spring is located in the groove and fixedly connected with the wedge-shaped block and the groove bottom surface at both ends, at this time the wedge-shaped block is clamped with the clamping groove 210a to realize the relative fixation of the position between the shell 110 and the outer shell 210 of the pen body 200.

[0038] By designing the clamping piece 130, the clamping piece 130 is clamped and matched with the clamping groove 210a on the side wall of the outer shell 210, so as to realize the relative fixation of the position between the shell 110 and the outer shell 210 of the pen body 200, thereby assembling the battery module 100 on the pen body 200, which is simple in structure and convenient to realize.

[0039] Specifically, as Figures 4-6As shown, the circumferential wall 112 is provided with an avoiding groove 112a corresponding to the clamping groove 210a of the outer shell 210; the clamping piece 130 comprises a connecting portion 131 and a clamping spring 132, the connecting portion 131 is connected with the circumferential wall 112, and the clamping spring 132 is arranged corresponding to the avoiding groove 112a and connected with the connecting portion 131; when the shell 110 is positioned on the outer shell 210 of the pen body 200, the clamping spring 132 is clamped with the clamping groove 210a of the outer shell 210.

[0040] The connecting portion 131 is an intermediate connecting structure between the clamping spring 132 and the circumferential wall 112; here, the specific connection mode between the connecting portion 131 and the circumferential wall 112 is not limited, and the designer can reasonably design according to actual needs; for example, the connecting portion 131 can be, but is not limited to, detachably connected with the circumferential wall 112 by at least one of the modes such as screwing, clamping or inserting; for another example, the connecting portion 131 can also be, but is not limited to, non-detachably connected with the circumferential wall 112 by the modes such as gluing, injection molding or 3D printing. It can be understood that the specific form of the connecting portion 131 can be various, and the specific connection mode between the connecting portion 131 and the circumferential wall 112 is also not the same for different forms of the connecting portion 131; for example, the connecting portion 131 can comprise a connecting protrusion (not shown in the figure), the circumferential wall 112 is provided with a positioning groove (not shown in the figure) adjacent to the avoiding groove 112a, and the connecting protrusion is matched with the positioning groove to position the clamping spring 132 on the circumferential wall 112; for another example, the connecting portion 131 can also comprise a screw (not shown in the figure), and the circumferential wall 112 is provided with a threaded hole (not shown in the figure) adjacent to the avoiding groove 112a, the screw is threaded through the clamping spring 132 and connected with the threaded hole to position the clamping spring 132 on the circumferential wall 112.

[0041] The clamping spring 132 is in a strip shape, and the clamping spring 132 is suitable for elastic deformation under stress and can automatically recover the elastic deformation after the external force disappears; by designing the avoiding groove 112a corresponding to the clamping spring 132 on the circumferential wall 112, the avoiding groove 112a can reserve sufficient deformation space for the clamping spring 132, so that the clamping spring 132 can produce good elastic deformation, on the one hand, to enhance the connection stability between the shell 110 and the outer shell 210 of the pen body 200, and on the other hand, to facilitate the disassembly between the shell 110 and the outer shell 210 of the pen body 200.

[0042] More specifically, as Figures 4-6As shown, the connecting part 131 comprises a connecting ring 1311 which is attached to the peripheral side wall 112, and the annular surface of the connecting ring 1311 is provided with a through slot 1311a corresponding to the avoiding slot 112a, and the clamping elastic sheet 132 is arranged corresponding to the through slot 1311a and fixedly connected with the connecting ring 1311. Wherein, the connecting ring 1311 and the clamping elastic sheet 132 are integrally formed. By designing the connecting part 131 as the connecting ring 1311, the contact area between the connecting ring 1311 and the peripheral side wall 112 is larger, which can enhance the connection stability between the clamping part 130 and the peripheral side wall 112, and the connecting ring 1311 has a larger volume itself to provide good support for the clamping elastic sheet 132, and the connecting ring 1311 can also be used as a reinforcing body to improve the structural strength of the peripheral side wall 112.

[0043] The connecting ring 1311 is provided with a notch 1311b, and the design of the notch 1311b allows the radial dimension of the connecting ring 1311 to change under external force, so as to facilitate the installation and disassembly between the clamping part 130 and the peripheral side wall 112.

[0044] Of course, in other embodiments, when the shell 110 is connected with the shell 210 of the pen body 200; it can also be that the peripheral side wall 112 is provided with a clamping groove 210a for clamping and cooperating with the clamping part 130 of the pen body 200 to position the shell 110 on the shell 210 of the pen body 200, thereby achieving the installation between the battery module 100 and the pen body 200. It should be noted that the specific form of the clamping part 130 provided on the shell 210 of the pen body 200 can refer to the above description of the clamping part 130, which will not be repeated here.

[0045] As shown in Figure 6 The battery 120 is detachably installed in the accommodating cavity 110a of the shell 110. When the battery 120 is a dry battery 120, the user can directly take out the dry battery 120 with depleted or damaged power from the accommodating cavity 110a of the shell 110 and replace it with a new dry battery 120, which is convenient to operate. In this way, the user does not need to discard the entire battery module 100 due to the depletion or damage of the dry battery 120, thereby further reducing the user's use cost. When the battery 120 is a lithium battery 120, the user can directly take out the damaged lithium battery 120 from the accommodating cavity 110a of the shell 110 and replace it with a new lithium battery 120, which is convenient to operate. In this way, the user does not need to discard the entire battery module 100 due to the damage of the lithium battery 120, thereby further reducing the user's use cost.

[0046] Specifically, the shell 110 comprises a barrel 113 and a cover 114, at least part of the barrel 113 is covered by the side wall of the outer shell 210, the cover 114 is movably connected with the barrel 113 to open or close the barrel opening of the barrel 113, and the cover 114 and the barrel 113 jointly enclose the accommodating cavity 110a. Wherein, the specific movable connection mode between the cover 114 and the barrel 113 is not limited here, and the designer can reasonably design according to the actual needs; for example, the cover 114 can be but not limited to movably connected with the barrel 113 through a rotating shaft, and for another example, the cover 114 can also be but not limited to movably connected with the barrel 113 through a sliding groove. By movably connecting the cover 114 with the barrel 113, the cover 114 moves relative to the barrel 113 to open or close the opening of the barrel 113, so as to realize the disassembly of the battery 120, which is simple in structure and convenient to operate. Of course, as shown in Figure 7 in other embodiments, the cover 114 can also be fixedly connected with the barrel 113 through the buckle 115.

[0047] As shown in Figures 4-6 the battery module 100 further comprises an interface 140, which is installed on the shell 110 and electrically connected with the battery 120, and is used to be plugged with the connector 222 of the control assembly 220 when the shell 110 is positioned in the outer shell 210 of the pen body 200, so as to realize the electrical conduction between the interface 140 and the connector 222 of the control assembly 220. By designing the interface 140, when the shell 110 is positioned in the outer shell 210 of the pen body 200, the interface 140 is plugged with the connector 222 of the control assembly 220 to realize the electrical conduction, compared with the mode of directly using the electrical contact and the electrical sheet to cooperate to realize the electrical conduction, the plug-in cooperation between the interface 140 and the connector 222 of the control assembly 220 can make up for the problem of poor electrical contact caused by the assembly error along the direction of the central axis of the stylus 10. It is worth mentioning that, in addition to the electrical connection between the interface 140 and the connector 222 of the control assembly 220, there is also a structural connection, and in cooperation with the clamping between the clamping piece 130 and the clamping groove 210a, the double fixation between the shell 110 and the outer shell 210 of the pen body 200 can be realized, so as to effectively enhance the connection stability between the battery module 100 and the pen body 200.

[0048] Specifically, the interface 140 is installed on the cover 114, the end surface of the cover 114 facing the barrel 113 is pre-buried with a first electrical connecting piece (not shown in the figure, such as a conductive ring), the first electrical connecting piece is electrically connected with the interface 140, the end surface of the barrel 113 facing the cover 114 is pre-buried with a second electrical connecting piece (not shown in the figure, such as another conductive ring), and the second electrical connecting piece is electrically connected with the circuit board 150 of the battery module 100, when the cover 114 closes the barrel opening of the barrel 113, the first electrical connecting piece and the second electrical connecting piece are in contact, so that the circuit between the battery 120 and the interface 140 is conducted.

[0049] The interface 140 can include a male plug electrically connected with the battery 120, and the connector 222 can include a female socket electrically connected with the mainboard 221 of the control assembly 220. When the shell 110 is positioned in the outer shell 210 of the pen body 200, the male plug as the interface 140 is plugged with the female socket as the connector 222. Of course, the interface 140 can also include a female socket electrically connected with the battery 120, and the connector 222 can also include a male plug electrically connected with the mainboard 221 of the control assembly 220. When the shell 110 is positioned in the outer shell 210 of the pen body 200, the female socket as the interface 140 is plugged with the male plug as the connector 222.

[0050] In the plugging direction of the male plug and the female socket, the fitting depth of the male plug and the female socket is greater than or equal to 1.5 mm and less than or equal to 3.0 mm. For example, the fitting depth of the male plug and the female socket can be, but is not limited to, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3.0 mm, etc. Wherein, the "fitting depth" is understood as the length of the pin of the male plug and the pin of the female socket in the direction of the central axis of the stylus 10. By reasonably designing the fitting depth of the male plug and the female socket, even if there is an assembly error in the direction of the central axis of the stylus 10, the male plug and the female socket can be plugged, and the pin of the male plug and the pin of the female socket can form effective contact.

[0051] As shown in Figures 1-4 The pen body 200 detachably matched with the battery module 100 includes an outer shell 210 and a control assembly 220.

[0052] The outer shell 210 is a shell part of the pen body 200. Here, the specific material of the outer shell 210 is not limited, and the designer can reasonably select according to the actual needs; for example, the material of the outer shell 210 can be, but is not limited to, plastic, silica gel or rubber, etc.

[0053] The outer shell 210 has a cavity 210b, which is a hollow area inside the outer shell 210. Here, the specific shape of the cavity 210b is not limited, and the designer can reasonably design according to the actual needs; for example, the shape of the cavity 210b can be, but is not limited to, a cylindrical shape.

[0054] The control assembly 220 is the control center of the pen body 200, and the control assembly 220 is used to control the working mode of the stylus 10; the specific structure of the control assembly 220 will be introduced below.

[0055] The control assembly 220 is arranged in the cavity 210b of the shell 210. The specific mounting manner between the control assembly 220 and the shell 210 is not limited here, and the designer can reasonably design according to actual needs; for example, a mounting bracket is arranged in the cavity 210b of the shell 210, and the control assembly 220 is mounted on the mounting bracket.

[0056] The shell 210 is used for detachable connection with the battery module 100 of the stylus 10, so as to realize detachable connection between the entire pen body 200 and the battery module 100 of the stylus 10, so as to facilitate the user to replace the pen body 200 with zero power or damage or the damaged battery module 100 in time. The specific detachable connection manner between the shell 210 and the battery module 100 of the stylus 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the shell 210 and the battery module 100 (specifically the shell 110 of the battery module 100) of the stylus 10 can be detachably connected through threaded connection; for another example, the shell 210 and the battery module 100 (specifically the shell 110 of the battery module 100) of the stylus 10 can be detachably connected through clamping connection; for another example, the shell 210 and the battery module 100 (specifically the shell 110 of the battery module 100) of the stylus 10 can be detachably connected through plug-in connection; for another example, the shell 210 and the battery module 100 (specifically the shell 110 of the battery module 100) of the stylus 10 can be detachably connected through magnetic attraction.

[0057] When the shell 210 is assembled on the shell 110 of the battery module 100, the control assembly 220 is used in cooperation with the battery 120 of the battery module 100 to receive the electric energy provided by the battery 120 of the battery module 100; when the shell 210 is detached from the shell 110 of the battery module 100, the battery 120 of the battery module 100 stops supplying power to the control assembly 220. It should be noted that the control assembly 220 can receive the electric energy provided by the battery 120 of the battery module 100 through wired charging, for example, the control assembly 220 and the battery 120 of the battery module 100 can be electrically connected through the cooperation of the electric contact and the electric sheet at this time; the control assembly 220 can also receive the electric energy provided by the battery 120 of the battery module 100 through wireless charging, for example, the control assembly 220 and the battery 120 of the battery module 100 can be electrically connected through the cooperation of the wireless transmitting coil and the wireless receiving coil at this time.

[0058] The side wall of the tail end of the outer shell 210 forms an inner-outer nested structure with the shell 110 of the battery module 100. For example, the side wall of the tail end of the outer shell 210 can wrap the shell 110 of the battery module 100, in which case the outer shell 210 is sleeved on the shell 110 of the battery module 100; for another example, the side wall of the tail end of the outer shell 210 can be wrapped by the shell 110 of the battery module 100, in which case the shell 110 of the battery module 100 is sleeved on the outer shell 210; for still another example, the side wall of the tail end of the outer shell 210 can wrap the shell 110 of the battery module 100, and the side wall of the tail end of the outer shell 210 can be wrapped by the shell 110 of the battery module 100, in which case the outer shell 210 and the shell 110 of the battery module 100 form a multi-layer inner-outer nested structure. It should be noted that the "the side wall of the tail end of the outer shell 210 wraps the shell 110 of the battery module 100" can mean that the entire shell 110 is inserted into the accommodating cavity 110a of the outer shell 210, or that part of the shell 110 is inserted into the accommodating cavity 110a of the outer shell 210, and the remaining part of the shell 110 is inserted out of the accommodating cavity 110a of the outer shell 210.

[0059] As shown in Figures 4-6 When the outer shell 210 is connected with the shell 110 of the battery module 100, the side wall of the outer shell 210 can be provided with a clamping groove 210a, which is used for clamping cooperation with the clamping piece 130 of the battery module 100, so as to position the outer shell 210 on the shell 110 of the battery module 100, thereby realizing the installation between the pen body 200 and the battery module 100. It should be noted that the specific form of the clamping piece 130 can refer to the above description, which will not be repeated here.

[0060] When the outer shell 210 is connected with the shell 110 of the battery module 100, the pen body 200 further comprises a clamping piece 130, which is connected with the side wall of the outer shell 210, and is used for clamping cooperation with the clamping groove 210a of the shell 110, so as to position the outer shell 210 on the shell 110 of the battery module 100, thereby realizing the installation between the pen body 200 and the battery module 100. It should be noted that the specific form of the clamping piece 130 can refer to the above description, which will not be repeated here.

[0061] As shown in Figure 4As shown, the control assembly 220 includes a main board 221 and a connector 222, the main board 221 is installed in the cavity 210b of the shell 210, the connector 222 is arranged at one end of the main board 221 close to the tail end of the shell 210, the connector 222 is electrically connected with the main board 221, and the connector 222 is used for plugging with the interface 140 of the battery module 100 when the shell 210 is positioned in the shell 110 of the battery module 100, so as to realize electrical conduction between the connector 222 and the interface 140 of the battery module 100. The main board 221 is used for controlling the working mode of the stylus 10, and the main board 221 can be installed on the above-mentioned support, and the connector 222 can be directly welded on the main board 221. By designing the connector 222, when the shell 210 is positioned in the shell 110 of the battery module 100, the connector 222 is plugged with the interface 140 of the battery module 100 to realize electrical conduction. Compared with the mode of directly using electrical contacts and electrical sheets to realize electrical conduction, the plugging of the connector 222 with the interface 140 of the battery module 100 can compensate for the problem of poor electrical contact caused by assembly error along the direction of the central axis of the stylus 10. It is worth mentioning that, in addition to the electrical connection between the connector 222 and the interface 140 of the battery module 100, there is also a structural connection. In combination with the clamping between the clamping piece 130 and the clamping groove 210a, the double fixation between the shell 210 and the shell 110 of the battery module 100 can be realized, so as to effectively enhance the connection stability between the pen body 200 and the battery module 100.

[0062] The connector 222 can include a male plug electrically connected with the main board 221, and the interface 140 can include a female socket electrically connected with the battery 120 of the battery module 100. When the shell 210 is positioned in the shell 110 of the battery module 100, the male plug as the connector 222 is plugged with the female socket as the interface 140. Of course, the connector 222 can also include a female socket electrically connected with the main board 221, and the interface 140 can also include a male plug electrically connected with the battery 120 of the battery module 100. When the shell 210 is positioned in the shell 110 of the battery module 100, the female socket as the connector 222 is plugged with the male plug as the interface 140.

[0063] As shown in the drawings, Figure 8 The socket of the female socket as the connector 222 is provided with a guide slope 222a. By designing the guide slope 222a, the guide slope 222a has a guiding effect on the male plug as the interface 140, which is conducive to realizing the plugging cooperation between the female socket and the male plug, and reducing the wear of the two.
