[0001] The present application relates to the field of electronics, and in particular to plug adapters. [Background technology]

[0002] Nowadays, global travel is becoming more and more popular. Since socket specifications are different in different countries or regions, people usually need to carry multi-country plug adapters to adapt to the plugs of their portable electrical or electronic products for ease of use.

[0003] Currently, many of the plug adapters commonly seen on the market are thick, heavy, and difficult to carry. The plug adapter contains multiple plug assemblies that can be used with different socket specifications. When one plug assembly is pushed to extend from the plug adapter, it is easy for the other multiple plug assemblies to interfere with or become locked together, resulting in two or more plug assemblies extending from the plug adapter at the same time. This not only affects normal use, but also poses safety issues such as electric shock to the user, sparks inside the socket, or fires due to the socket overheating, potentially creating safety risks. Summary of the Invention

[0021] The present application first provides a plug adapter, and as shown in FIGS. 1 to 12, FIG. 1 is a schematic configuration diagram of one embodiment of the plug adapter of the present application.

FIG. 7 is a schematic configuration diagram of one embodiment of a second slider of the present application. FIG. 8 is a schematic cross-sectional view taken along section A of the embodiment of FIG. 4. FIG. 9 is a schematic configuration diagram of one embodiment of an operating member of the present application. FIG. 10 is a partial schematic configuration diagram of one embodiment of the plug adapter of the present application. FIG. 11 is a partial schematic configuration diagram of one embodiment of the plug adapter of the present application. FIG. 12 is a schematic cross-sectional view taken along section B of the embodiment of FIG. 4. The plug adapter includes a support member 01, a first slider 02, a first plug assembly 03, and a second plug assembly 04. The support member 01 is provided with a first insertion hole 11 (including 11a, 11b, and 11c) and a second insertion hole 12. The first slider 02 is slidably connected to the support member 01 along a first direction x. The first slider 02 is provided with a first end 21 and a second end 22 arranged along the first direction x. The plug 03 is provided on the support member 01 and is extendable in the first insertion hole 11 along the second direction y so that at least a portion of the plug 03 abuts against the first end 21 or is separated from the first end 21, and the second plug assembly 04 is provided on the support member 01 and is extendable in the second insertion hole 12 along the second direction y so that at least a portion of the plug 03 abuts against the second end 22 or is separated from the second end 22, the second direction y being perpendicular to the first direction x.

[0022] The first slider 02 is slidably connected to the support member 01 along the first direction x, and the support member 01 restricts the position of the first slider 02, thereby enabling the first slider 02 to slide left and right only along the first direction x.

[0023] As shown in Figures 4 and 8, when the first plug assembly 03 or the second plug assembly 04 moves in the second direction y, it pushes the first slider 02 to slide left and right in the first direction x, and the three can mutually realize positional restrictions. Specifically, when at least a portion of the first plug assembly 03 extends from the first insertion hole 11 along the second direction y, at least a portion of the first plug assembly 03 abuts against the first end 21 of the first slider 02, and by pushing the first slider 02 to move along the first direction x, the second end 22 covers at least a portion of the second insertion hole 12, thereby preventing the second plug assembly 04 from extending from the second insertion hole 12; when at least a portion of the second plug assembly 04 extends from the second insertion hole 12 along the second direction y, the second plug assembly 04 abuts against the second end 22 of the first slider 02, and by pushing the first slider 02 to move along the first direction x, the first end 21 covers at least a portion of the first insertion hole 11, thereby preventing the first plug assembly 03 from extending from the first insertion hole 11.

[0024] Preferably, a first groove 41 is provided on the side of the second plug assembly 04 that is closest to the first slider 02, and the first slider 02 is engaged with and engaged into the first groove 41, thereby achieving contact between the second plug assembly 04 and the first slider 02.

[0025] That is, the second plug assembly 04 can achieve positional contact between the first slider 02 and the second plug assembly 04 via the first groove 41. For example, as shown in FIG. 8 , the second end 22 of the first slider 02 enters the first groove 41, thereby limiting the position of the second end 22 of the first slider 02 relative to the second plug assembly 04 and preventing the second plug assembly 04 from extending out of the second insertion hole 12. In one application scenario, the fourth plug assembly 010 is a European standard round plug assembly, and this design can improve the anti-ejection effect and corresponding user experience compared to a European standard round socket assembly.

[0026] In other embodiments, similar structures of the first grooves can be used in other socket assemblies to further improve the anti-extrusion effect.

[0027] Preferably, as shown in Figures 2, 4 to 8 and 12, the support member 01 is further provided with a third insertion hole 13 (including 13a, 13b, and 13c), and the plug adapter further includes a second slider 08 and a third plug assembly 09, wherein the second slider 08 is slidably connected to the support member 01 along a third direction z, the third direction z being perpendicular to the first direction x and the second direction y, and the third plug assembly 09 is provided on the support member 01 and is extendable and retractable in the third insertion hole 13 along the second direction y so as to abut against or separate from the second slider 08, and the first slider 02 is provided with a first engaging portion 23, and the second slider 08 includes a second engaging portion 83, and the first engaging portion 23 and the second engaging portion 83 are engaged with or separated from each other along the first direction x or the third direction z.

[0028] The second slider 08 is connected to the support member 01 so as to be slidable in the third direction z, and the support member 01 restricts the position of the second slider 08, thereby enabling the second slider 08 to slide left and right only in the third direction z. The first and second sliders 02 and 08 restrict each other's positions by the first and second engaging portions 23 and 83.

[0029] 4, 5, and 8, the first slider 02, the second slider 08, the first plug assembly 03, the second plug assembly 04, and the third plug assembly 09 can achieve positional limitations. Specifically, when at least a portion of the first plug assembly 03 extends from the first insertion hole 11, it abuts against the first end 21 and pushes the first slider 02 to move along the first direction x, thereby achieving abutment between the second end 22 of the first slider 02 and the second plug assembly 04, and further realizing a positional limitation for the second plug assembly 04 (same as in the above embodiment). At the same time, (as shown in FIG. 5) the movement of the first slider 02 along the first direction x is also limited. As a result, the first engagement portion 23 pushes the second engagement portion 83 to move along the third direction z until the second engagement portion 83 and the first engagement portion 23 are fully engaged and positionally restricted, thereby positioning the second slider 08 at a second predetermined position, and at this time, one side of the second slider 08 covers at least a portion of the third insertion hole 13, preventing the third plug assembly 09 from extending from the third insertion hole 13 and realizing positional restriction of the third plug assembly 09.

[0030] As shown in Figures 5 and 12, when at least a portion of the third plug assembly 09 extends from the third insertion hole 13 along the second direction y, the third plug assembly 09 abuts against the second slider 08 and pushes the second slider 08 to move along the third direction z, whereby the second engagement portion 83 pushes the first engagement portion 23 to move along the first direction x until the first engagement portion 23 and the second engagement portion 83 are fully engaged with each other and restricted in position, thereby positioning the first slider 02 at a third predetermined position, at which time the first end 21 of the first slider 02 covers at least a portion of the first insertion hole 11 and the second end 22 of the first slider 02 covers at least a portion of the second insertion hole 12, preventing the first plug assembly 03 from extending from the first insertion hole 11 and the second plug assembly 04 from extending from the second insertion hole 12.

[0031] In the above embodiment, when the first engaging portion 23 and the second engaging portion 83 are fully engaged, the first slider 02 stops sliding in the first direction x, and the second slider 08 stops sliding in the second direction y, so that the plug portion of the first plug assembly 03 abuts against the first end 21 of the first slider 02, further fixing the positions of the first slider 02 and the second slider 08 and further improving the anti-push effect for the second plug assembly 04 and the third plug assembly 09. Similarly, when the user needs to use the second plug assembly 04, the first slider 02 and the second slider 08 will generate a similar interlocking effect as described above, thereby achieving the anti-push effect for the first plug assembly 03 and the third plug assembly 09.

[0032] With the rapid development of the economy, global travel is becoming increasingly popular. Because socket specifications vary between countries or regions, people typically need to carry multiple international plug adapters to accommodate the plugs of their portable electrical or electronic products for ease of use. Currently, most plug adapters on the market are bulky and difficult to carry. Furthermore, because the plug adapters themselves contain multiple plug assemblies that can be used with different socket specifications, when one plug assembly is pushed out of the plug adapter for use, the other multiple plug assemblies are likely to interfere with or become locked together. This can result in two or more plug assemblies simultaneously extending from the plug adapter, which not only affects normal use but also poses safety risks, such as electric shock to the user, sparks within the socket, or fires due to overheating of the socket.

[0033] In this embodiment, the support member 01 is provided with a first slider 02 that slides along the first direction x, and the support member 01 restricts the position of the first slider 02, thereby enabling the first slider 02 to slide left and right only along the first direction x. The first slider 02 can cover at least a part of the second insertion hole 12 when the first plug assembly 03 extends from the first insertion hole 11, and can further reduce the risk that the second plug assembly 04 will be interfered with or pulled out of the second insertion hole 12 when the first plug assembly 03 extends from the first insertion hole 11. Similarly, when the second plug assembly 04 extends from the second insertion hole 12, the first slider 02 covers at least a part of the first insertion hole 11, thereby reducing the risk that the first plug assembly 03 will be interfered with or pulled out of the first insertion hole 11. The second slider 08 and the first slider 02 can be engaged or disengaged by the first engaging portion 23 and the second engaging portion 83, and the second slider 08 can be engaged or disengaged with the third plug assembly 09. This restricts the relative positions of the first plug assembly 03, the second plug assembly 04, and the third plug assembly 09, reducing the risk of multiple plug assemblies in the plug adapter being ejected simultaneously. This embodiment has a simple structure, prevents interference between multiple plug assemblies without the need for additional position restriction mechanisms, reduces the overall size of the plug adapter, and improves product portability. This embodiment also has a simple structure, making it easy to reuse the plug adapter or to add functional modules with different specifications within the plug adapter. Therefore, this embodiment better reduces the risk of multiple plug assemblies in the plug adapter being ejected simultaneously, improving the convenience and safety of the plug adapter, reducing the size of the product and improving portability, reducing safety risks, and improving product reliability and user experience.

[0034] In addition, such a cross-sliding structure is strong, slides smoothly, improves the user experience, has a simple structure, occupies a small space for components, and does not require the addition of other position limiting mechanisms, thereby reducing the space occupied by the product and improving portability.

[0035] In other embodiments, multiple sets of plug assemblies or other functional modules can be added using the above principles, and this design structure is simple and easy to produce, reducing costs and improving the compactness of the internal structure of the product, further reducing the size of the product and improving its portability.

[0036] Preferably, the support member 01 is provided with a position limiting assembly that limits the movement of the first slider 02 along the first direction x.

[0037] By providing the position limiting assembly on the support member 01, the stability of the first slider 02 when it moves along the first direction x can be improved, and the reliability of the product can be further improved.

[0038] Preferably, the position limiting assembly may be a position limiting protrusion, so as to realize the restriction of the first slider 02 only along the first direction x, and to facilitate assembly.

[0039] In another embodiment, the position limiting assembly may be a slide rail and may include a slide block corresponding to the first slider, so as to limit the movement of the first slider along the first direction and further improve the stability of the first slider during sliding.

[0040] Preferably, the plug adapter further includes an upper case 05 and a lower case 06, and the upper case 05 has a first through hole 51 (including 51a, 51b, 51c) communicating with the first insertion hole 11 and a second through hole 52 communicating with the second insertion hole 12, and the lower case 06 forms an accommodating cavity together with the upper case 05, and the support member 01, the first slider 02, the first plug assembly 03, and the second plug assembly 04 are provided in the accommodating cavity.

[0041] In one application scenario, the upper case 05 and the lower case 06 form an accommodating cavity, and the plug portion of the first plug assembly 03 extends from the first insertion hole 11 along the second direction y and may further extend from the first through hole 51 for use, and the plug portion of the second plug assembly 04 extends from the second insertion hole 12 along the second direction y and may further extend from the second through hole 52 for use. When the first plug assembly 03 extends from the first through hole 51, the plug portion of the first plug assembly 03 pushes the first end 21 of the first slider 02 to move along the first direction x away from the first insertion hole 11, so that the second end 22 of the first slider 02 covers at least a portion of the second insertion hole 12 and prevents the second plug assembly 04 from extending from the second insertion hole 12; when the second plug assembly 04 extends from the second through hole 52, the plug portion of the second plug assembly 04 pushes the second end 22 of the first slider 02 to move along the first direction x away from the second insertion hole 12, so that the first end 21 of the first slider 02 covers at least a portion of the first insertion hole 11 and prevents the first plug assembly 03 from extending from the first insertion hole 11, further improving safety in use.

[0042] The beneficial effect of the above installation is that the design of the upper case 05 and the lower case 06 can improve the aesthetics and safety of the plug adapter, and improve the anti-interference performance and reliability of the product.

[0043] Preferably, the plug adapter further includes three operating members 07, which are respectively connected to the first plug assembly 03, the second plug assembly 04, and the third plug assembly 09, and control the first plug assembly 03 to extend and retract into the first insertion hole 11, the second plug assembly 04 to extend and retract into the second insertion hole 12, and the third plug assembly 09 to extend and retract into the third insertion hole 13.

[0044] In one application scenario, a user can use an operating member 07 connected to the first plug assembly 03 to control the first plug assembly 03 to extend from the first insertion hole 11, and when use of the first plug assembly 03 is complete, the user can use the operating member 07 to control the first plug assembly 03 to retract, i.e., reset, into the first insertion hole 11. In one application scenario, the first plug assembly 03 may be configured such that, at the beginning of the reset process, at least a portion of the structure of the first plug assembly 03 always abuts against the first end 21 of the first slider 02, and at the later stage of the reset process, the structure where the first plug assembly 03 and the first slider 02 abut falls completely into the first insertion hole 11, at which time the first plug assembly 03 does not affect the first slider 02, and at this time the first slider 02 bounces back to its original position and covers at least a portion of the first insertion hole 11, or the first slider 02 may be configured to maintain its current position and not move, and is not specifically limited.

[0045] Similarly, in one application scenario, a user can use the operating member 07 connected to the second plug assembly 04 or the third plug assembly 09 to control the second plug assembly 04 to extend from the second insertion hole 12. For example, when use of the second plug assembly 04 is complete, the operating member 07 can be used to control the second plug assembly 04 to completely drop, or reset, the structure in which the second plug assembly 04 abuts against the first slider 02 into the second insertion hole 12. The operation of the third plug assembly 09 is similar, and a description thereof will be omitted here.

[0046] The beneficial effect of the above arrangement is that the provision of the operating member 07 facilitates the user's operation and control of the extension and contraction of the first plug assembly 03, the second plug assembly 04 or the third plug assembly 09, thereby improving the user's usage experience.

[0047] Preferably, a position limiting column 15 extends along the second direction y on the side of the support member 01 opposite the first slider 02, and a position limiting hole 71 is provided in the operating member 07, and at least a portion of the position limiting column 15 is provided within the position limiting hole 71.

[0048] 10 , in one application scenario, the support member 01 is provided with two position limiting posts 15 corresponding to two operating members 07, respectively, and at least a portion of the position limiting posts 15 is disposed within the position limiting holes 71, allowing the operating members 07 to move along the extending direction of the position limiting posts 15. The position limiting posts 15 provide support and position limiting functions for the movement of the operating member 07, allowing the operating member 07 to move only along the second direction y, improving the accuracy of the movement direction and stability of the movement of the operating member 07. This allows the first socket assembly or the second socket assembly to more accurately extend and retract into the first insertion hole 11 or the second insertion hole 12 along the second direction y, improving the accuracy of the movement direction and stability of the movement of the first socket assembly or the second socket assembly, and further improving the user experience.

[0049] In another embodiment, the support member may include only one position limiting post at least partially disposed within the two position limiting holes of the two operating members, and the two operating members can move along the extension direction of the position limiting post, i.e., along the second direction.

[0050] Preferably, as shown in FIG. 10 , the cross-sectional dimension of one end of the position limiting post 15 adjacent to the first slider 02 is smaller than the dimension of the other end so that a slide groove 151 is formed at one end of the position limiting post 15, and the operating member 07 includes a fixed part 72, an operating part 73, and an elastic member 74, the fixed part 72 is slidably connected to the first plug assembly 03 or the second plug assembly 04 along a direction perpendicular to the second direction y, the operating part 73 is provided on the fixed part 72, and the elastic member 74 has one end connected to the fixed part 72 and the other end connected to the first plug assembly 03 or the second plug assembly 04 and is provided to extend along the sliding direction of the fixed part 72, and the depth direction of the slide groove 151 is the same as the sliding direction of the fixed part 72.

[0051] In one application scenario, the position limiting hole 71 of the operating member 07 is provided in the fixed part 72. When a user intends to use the first plug assembly 03 or the second plug assembly 04, the user controls the operating member 07 to move to a position close to the first slider 02 along the second direction y. When the operating member 07 passes through the position limiting hole 71 and moves to the slide groove 151 of the position limiting column 15, the cross-sectional dimension of one end of the position limiting column 15 that is close to the first slider 02 is smaller than the dimension of the other end, and the depth direction of the slide groove 151 is the same as the sliding direction. Therefore, the elastic member 74 As a result of this action, the fixing portion 72 slides relative to the first plug assembly 03 or the second plug assembly 04 in a direction perpendicular to the second direction y, and is finally engaged with the slide groove, so that the operating member 07 engages with the slide groove 151 of the position limiting post 15. At this time, the slide groove 151 provides a supporting force to the operating member 07 and the first plug assembly 03 or the second plug assembly 04 slidably connected to the operating member 07, and further realizes the position fixation of the first plug assembly 03 or the second plug assembly 04, which can facilitate normal use by the user.

[0052] Furthermore, when use of the first plug assembly 03 or the second plug assembly 04 is completed, the user presses the operating member 07 along the extension direction of the elastic member 74 to compress the elastic member 74, causing the fixing portion 72 to slide toward the first plug assembly 03 or the second plug assembly 04 along the extension direction of the elastic member 74, resetting the position limiting hole 71 so that the operating member 07 is no longer supported by the slide groove 151 of the position limiting column 15, and the operating member 07 then passes through the position limiting hole 71 and drives the first plug assembly 03 or the second plug assembly 04 along the position limiting column 15 to move in the second direction y away from the first insertion hole 11 or the second insertion hole 12, thereby completing the resetting and storage of the first plug assembly 03 or the second plug assembly 04.

[0053] The beneficial effects of the above-described arrangement are as follows: the fixing part 72 is slidably connected to the first plug assembly 03 or the second plug assembly 04 along a direction perpendicular to the second direction y, and the depth direction of the sliding groove 151 is the same as the sliding direction. Therefore, when the fixing part 72 moves to the position of the sliding groove 151 of the position limiting post 15, the fixing part 72 is easily engaged with the sliding groove 151 due to the action of the elastic member 74. The sliding groove 151 is easily able to provide a supporting force to the operating member 07 and the first plug assembly 03 or the second plug assembly 04 slidably connected thereto, thereby realizing the positional fixation of the first plug assembly 03 or the second plug assembly 04. The provision of the fixing part 72 improves the control effect of the operating member 07 on the first plug assembly 03 or the second plug assembly 04. The provision of the operating part 73 makes it easier for the user to operate the operating member 07, improving the user experience. The provision of the elastic member 74 provides a driving force for the sliding of the fixing part 72, improving convenience and the user experience.

At least a portion of the operating member 07 is disposed in the slide grooves 53, and the portion where the fixing portion 72 of the operating member 07 is connected to the first plug assembly 03 or the second plug assembly 04 is located within the receiving cavity, while the operating portion 73 of the operating member 07 is located outside the receiving cavity, facilitating user operation. The design of the upper case 05 and the lower case 06 can improve the aesthetics and safety of the plug adapter.

[0062] In the above installation, it is only necessary to provide a first inclined surface and a second inclined surface on both ends of the first slider 02, which not only makes it easier to achieve the interlocking between the first plug assembly 03 or the second plug assembly 04 and the first slider 02, but also does not require the addition of additional parts, simplifies the structure, further reduces the dimensions of the product, improves the compactness of the layout of each part in the receiving cavity, and further improves the portability of the product.

[0063] In other embodiments, the above effect may be achieved by providing other mechanisms on both ends of the first slider, and there are no specific limitations.

This further improves the smoothness of the first plug assembly 03 pushing away the first end 21 of the first slider 02, and allows the first slider 02 to move toward a position away from the first insertion hole 11 in the second direction y. This arrangement improves the smoothness of user operation, more smoothly prevents the first slider 02 from protruding from the second plug assembly 04, and improves the safety of product use. Furthermore, when the second plug assembly 04 extends from the second insertion hole 12, a fourth inclined surface is provided parallel to the second inclined surface on the side of the second plug assembly 04 that is closest to the second end 22 of the first slider 02. This further improves the smoothness with which the second plug assembly 04 pushes away the second end 22 of the first slider 02, and allows the first slider 02 to move in the second direction y toward a position away from the second insertion hole 12. This arrangement improves the smoothness of user operation, more smoothly prevents the first slider 02 from protruding from the first plug assembly 03, and improves the safety of product use.

The bottom wall of the fourth engaging groove 831 is slidable in the first direction x, and a fifth engaging groove 832 and a sixth engaging groove 833 are further provided in the first direction x on the bottom wall of the fourth engaging groove 831, which can restrict the movement of the first engaging portion 23 in the first direction x and can restrict the movement of the first slider 02 in the first direction x. The first engaging portion 23 can restrict the position of the second slider 08, and the second engaging portion 83 can restrict the position of the first slider 02. The first engaging portion 23 and the second slider 08, and the second engaging portion 83 and the first slider 02, are fully engaged with each other to achieve relative sliding and position restriction.

[0076] Preferably, the two inner walls of the first engagement groove 231 facing each other along the first direction x are both arranged to form a V-shaped structure, for example, the V-shaped structure may be composed of two slopes, and the inner walls of the fifth engagement groove 832 and the sixth engagement groove 833 are both arranged to fit into the inner wall of the V-shaped structure formed by the two slopes of the first engagement groove 231, and the two inner walls of the fourth engagement groove 831 facing each other along the third direction z are both arranged to form a V-shaped structure, for example, the V-shaped structure may be composed of two slopes, and the inner walls of the second engagement groove 232 and the third engagement groove 233 are both arranged to fit into the inner wall of the V-shaped structure formed by the two slopes of the fourth engagement groove 831.

[0077] The above-mentioned installation has a simple structure, and the V-shaped structure makes it easy to convert the pushing force of the first slider 02 along the first direction x into a pushing force of the second slider 08 along the third direction z, or to convert the pushing force of the second slider 08 along the third direction z into a pushing force of the first slider 02 along the first direction x, thereby easily achieving good sliding and engagement position limiting effects.

[0078] In other embodiments, the shape of the first engaging portion and the shape of the second engaging portion can be adjusted to adjust the direction and distance in which the first slider and the second slider slide relative to each other, and can further meet the needs of products with different specifications.

[0082] Preferably, the plug adapter includes an upper case 05 and a lower case 06. If the plug adapter includes the second slider 08 and the third plug assembly 09, the plug adapter may include an operating member 07 connected to the third plug assembly 09, a position limiting post 15 of the support member 01, a slide groove 53 on the side wall of the upper case 05, and the third through hole, respectively. Specific embodiments are similar to the related descriptions for the first plug assembly 03 or the second plug assembly 04, and therefore will not be described here.

Similarly, when the user needs to use the second plug assembly 04, the first slider 02 and the second slider 08 will generate a similar interlocking effect to achieve the anti-push effect for the first plug assembly 03, the third plug assembly 09, and the fourth plug assembly 010.

[0086] The beneficial effects of the above arrangement are as follows: the fourth plug assembly 010 can further increase the variety of plug assemblies in the plug adapter, further improving the applicability of the product to various situations; furthermore, the interlocking arrangement of the second slider 08 and the first slider 02 can reduce the risk of multiple plug assemblies in the plug adapter being ejected at the same time; such a cross-sliding structure is strong, slides smoothly, improves the user experience, and is simple in structure, eliminating the need for additional position limiting mechanisms; it can reduce the risk of multiple plug assemblies being ejected at the same time when using a plug adapter that includes four different plug assemblies, further reducing the space occupied by the product and improving portability.

The function of the sixth inclined surface is similar, so a description thereof will be omitted here.

[0090] By simply forming the fifth and sixth inclined surfaces, the smoothness of the interlocking between the third plug assembly 09 or the fourth plug assembly 010 and the second slider 08 can be further improved, which not only simplifies the structure, improves the smoothness of user operation, and reduces the number and dimensions of the product's parts, but also more smoothly prevents the plug assemblies from protruding in a plug adapter having multiple sets of plug assemblies, thereby improving the safety of the product when used.

[0091] Preferably, in another embodiment, a seventh inclined surface may be provided on the side of the second slider of the third plug assembly adjacent to the third end, the seventh inclined surface being parallel to the fifth inclined surface, and a fourth plug assembly may have an eighth inclined surface on the side of the second slider of the fourth plug assembly adjacent to the third end, the sixth inclined surface being parallel to the sixth inclined surface.

While meeting the safety distance standard, this reduces the overall distance from the plug contour edge to the outer edge of the product, thereby realizing a smaller layout space. This arrangement further improves the plug adapter's applicability, enhances the user experience, and enhances the product's portability.

[0093] In another embodiment, the design principle of the first slider and the second slider intersecting and engaging can be used to add multiple plug assemblies or other functional modules to further expand the application scenarios of the plug adapter. This design structure is simple and easy to produce, reduces costs, improves the compactness of the internal structure of the product, further reduces the size of the product, and improves its portability.

[0099] In other embodiments, similar improvements can be made to the plug adapter and will not be described here.

[0100] Unlike the prior art, in the plug adapter of the present application, a first slider that slides along a first direction is provided on a support member, and the support member restricts the position of the first slider, thereby enabling the first slider to slide left and right only along the first direction. The first slider can cover at least a portion of the second insertion hole when the first plug assembly extends from the first insertion hole, and further can reduce the risk of the second plug assembly being interfered with or pulled out of the second insertion hole when the first plug assembly extends from the first insertion hole. Similarly, when the second plug assembly extends from the second insertion hole, the first slider covers at least a portion of the first insertion hole, thereby reducing the risk of the first plug assembly being interfered with or pulled out of the first insertion hole. The present invention provides a plug adapter with a simple structure, which prevents interference between multiple plug assemblies without the need for additional position-limiting mechanisms, thereby reducing the overall size of the plug adapter and improving its portability.
