[0046] Figure 5 for Figure 1 Magnified view of area A.
[0047] like Figure 1 and Figure 5 As shown, in some embodiments, the plug includes a first plug 10 and a second plug 12 . A first mating component is disposed on the outside of the first plug 10 , and a second mating component is disposed on the outside of the second plug 12 .
[0048] In some embodiments, a second buckle 9 is provided on a side of the first movable piece 4 away from the first buckle 5 , and the second buckle 9 is used to engage with the first matching component or the second matching component.
[0049] In some embodiments, the distance between one end of the first movable piece 4 away from the internal space of the assembly seat anti-trip buckle 3 (i.e., the outer end of the first movable piece 4) and the inner wall of the socket unit 1 is X, and the distance between one end surface of the assembly seat anti-trip buckle 3 away from the second buckle 9 (i.e., the outer side of the assembly seat anti-trip buckle 3) and the inner wall of the socket unit 1 is Y, and X>Y, that is, after the assembly seat anti-trip buckle 3 is installed inside the socket unit 1, the staff can also push the first movable piece 4 in the direction away from the internal space of the assembly seat anti-trip buckle 3 (i.e., push it outward) by extending the protrusion 7, so that the second buckle 9 can move outward to release the plug clamped inside the assembly seat anti-trip buckle 3.
[0050] In some embodiments, the second clip 9 has a second inclined surface, and the second inclined surface of the second clip 9 is arranged upward, and the second clip 9 can be engaged with the first matching component and the second matching component through the second inclined surface.
[0051] In some embodiments, the first mating component includes a stepped portion 11 located on the outer surface of the first plug 10, the bottom surface area of the stepped portion 11 is larger than the upper surface area of the first plug 10, and the lower part of the stepped portion 11 is movably inserted into the interior of the assembly seat anti-dropout buckle 3, that is, the bottom area of the first plug 10 is larger than the top area.
[0052] In some embodiments, the second mating component includes an empty groove 13 opened on two pairs of side walls of the second plug 12, and a second movable piece 14 is arranged inside each empty groove 13, and the lower end of the second movable piece 14 is fixedly connected to the second plug 12, and a third clip 15 and a pressing block 16 are fixedly arranged on a side wall away from each other of the two second movable pieces 14, and the pressing block 16 is located above the third clip 15, and the pressing block 16 is located at the upper end part of the second movable piece 14, and the distance between the upper end surface of the third clip 15 and the bottom surface of the second plug 12 is consistent with the distance between the upper end surface of the step portion 11 and the bottom surface of the first plug 10, and the second movable piece 14 can be pressed more conveniently by the pressing block 16.
[0053] In some embodiments, when the first plug 10 is inserted into the anti-drop buckle 3 of the assembly seat, the right-angled surface of the lower end of the second buckle 9 and the horizontal surface of the upper end of the step portion 11 are movably fitted, that is, when the second plug 12 is inserted into the interior of the anti-drop buckle 3 of the assembly seat, the third buckle 15 can be stuck under the second buckle 9.
[0054] The first plug 10 and the second plug 12 can be directly plugged into the socket unit 1, but there is no locking or anti-falling effect between the first plug 10 and the second plug 12 and the socket unit 1;
[0055] When the assembly seat anti-trip buckle 3 is pressed and assembled into the inside of the socket unit 1, the first buckle 5 on the outside of the assembly seat anti-trip buckle 3 can be mutually engaged with the limiting notch 2 of the socket unit 1. After engagement, the assembly seat anti-trip buckle 3 cannot be directly separated from the socket unit 1. The assembly seat anti-trip buckle 3, the first movable piece 4, and the first buckle 5 are all made of the same hard plastic material. Since the thickness of the first movable piece 4 is relatively small, the first movable piece 4 is similar to a plastic spring. When the assembly seat anti-trip buckle 3 is moved toward the socket unit 1, the protrusion of the first buckle 5 will push the first movable piece 4 to slightly deviate toward the inside of the assembly sleeve 3 until the first buckle 5 can contact the limiting notch 2. The first movable piece 4 rebounds with the first buckle 5 to reset, so that the first buckle 5 can be tightly engaged in the limiting notch 2. At this time, the first plug 10 or the second plug 12 is plugged into the inside of the assembly seat anti-trip buckle 3:
[0056] When the first plug 10 is assembled with the assembly seat anti-drop buckle 3, the bottom of the first plug 10 can directly squeeze the first movable piece 4 through the inclined surface of the second buckle 9, so that the first plug 10 can be smoothly inserted into the interior of the assembly seat anti-drop buckle 3. Since the assembly seat anti-drop buckle 3 and the first movable piece 4 are both made of plastic material, and the first movable piece 4 has a certain elastic deflection performance inside the opening groove 6, after the first plug 10 is completely inserted into the interior of the assembly seat anti-drop buckle 3, the first movable piece 4 will carry the second buckle 9 to perform a small reset movement, so that the second buckle 9 is buckled on the upper end surface of the step portion 11, so as to achieve the effect of clamping and limiting the first plug 10;
[0057] When the second plug 12 is assembled with the assembly seat anti-drop buckle 3, the third buckle 15 on the outer side of the second plug 12 will push the second buckle 9 away. When the second plug 12 is completely inserted into the assembly seat anti-drop buckle 3, the second buckle 9 will be buckled on the upper end surface of the third buckle 15, thereby playing a role in locking and limiting the second plug 12.
[0058] Both of the above two engaging modes can achieve the effect of preventing falling off, and the disassembly of the above two engaging assemblies is also very convenient. It is only necessary to open the two first movable pieces 4 through the extending protrusion 7, or to press the two second movable pieces 14 toward each other through the pressing block 16.
[0059] In an embodiment of the present application, the socket unit complies with the size standards of various sockets, including IEC60320-C13, IEC60320-C15, IEC60320-C19, and IEC60320-C21, and is adapted to the size standards of various plugs, including IEC60320-C14, IEC60320-C16, IEC60320-C20, and IEC60320-C22.
[0060] Figure 6ais a schematic diagram of the structure of the IEC60320-C14 plug shown in some embodiments of the present application; Figure 6b is a schematic diagram of the matching of the socket unit and the IEC60320-C14 plug shown in some embodiments of the present application;
[0061] Figure 6c It is a schematic diagram of the cooperation between the anti-drop socket unit with an assembly seat and the IEC60320-C14 plug shown in some embodiments of the present application.
[0062] like Figure 6a As shown, the IEC60320-C14 plug includes three types of plugs, which are, from left to right, a C14 standard plug 21, a C14-VLOCK plug 22, and a C14-PLOCK plug 23.
[0063] like Figure 6b As shown, from left to right, the C14 standard plug 21 is matched with the socket unit 1, the C14-VLOCK plug 22 is matched with the socket unit 1, and the C14-PLOCK plug 23 is matched with the socket unit 1. When the plug is a C14 standard plug 21, it can be directly inserted into the socket unit 1, but the plug and the socket unit 1 are not engaged at this time; when the plug is a C14-VLOCK plug 22, the buckle on the side of the plug is engaged with the limit slot 2 of the socket unit 1; when the plug is a C14-PLOCK plug 23, the buckle on the side of the plug is engaged with the limit bayonet 19 of the socket unit 1.
[0064] like Figure 6c As shown, from left to right, the C14 standard plug 21 cooperates with the socket unit 1 with the assembly seat anti-dropout buckle 3, the C14-VLOCK plug 22 cooperates with the socket unit 1 with the assembly seat anti-dropout buckle 3, and the C14-PLOCK plug 23 cooperates with the socket unit 1 with the assembly seat anti-dropout buckle 3. When the plug is a C14 standard plug 21, it can be directly inserted into the assembly seat anti-dropout buckle 3, but at this time, the plug and the assembly seat anti-dropout buckle 3 cooperate with the second buckle 9 of the assembly seat anti-dropout buckle 3 through the shaft shoulder of the plug; when the plug is a C14-VLOCK plug 22, the buckle on the side of the plug is engaged with the second buckle 9 of the assembly seat anti-dropout buckle 3; when the plug is a C14-PLOCK plug 23, the buckle on the side of the plug is engaged with the anti-dropout limit opening 20 of the assembly seat anti-dropout buckle 3.
[0065] Figure 7a is a schematic diagram of the structure of an IEC60320-C16 plug shown in some embodiments of the present application; Figure 7b It is a schematic diagram of the matching between the socket unit and the IEC60320-C16 plug shown in some embodiments of the present application.
[0066] like Figure 7aAs shown, the IEC60320-C16 plug includes a plug, namely a C16 plug 24, which does not have an anti-drop structure. Figure 7b As shown, similar to the C14 standard plug 21, when the C16 plug 24 is inserted into the socket unit 1, the C16 plug 24 can be powered on, but cannot be snapped into the socket unit 1. When the assembly seat anti-drop buckle 3 is used, the shoulder above the C16 plug 24 can be snapped into the second buckle 9 of the assembly seat anti-drop buckle 3, thereby achieving anti-dropping.
[0067] Figure 8a is a schematic diagram of the structure of an IEC60320-C20 plug shown in some embodiments of the present application; Figure 8b It is a schematic diagram of the matching between the socket unit and the IEC60320-C20 plug shown in some embodiments of the present application.
[0068] like Figure 8a As shown, the IEC60320-C20 plug includes three types of plugs, which are, from left to right, a C20 standard plug 25, a C20-PLOCK plug 26 and a C20-VLOCK plug 27.
[0069] like Figure 8b As shown, from left to right, the C20 standard plug 25 is matched with the socket unit 1, the C20-PLOCK plug 26 is matched with the socket unit 1, and the C20-VLOCK plug 27 is matched with the socket unit 1. When the plug is a C20 standard plug 25, it can be directly inserted into the socket unit 1, but the plug and the socket unit 1 are not engaged at this time; when the plug is a C20-PLOCK plug 26, the buckle on the side of the plug is engaged with the limit slot 2 of the socket unit 1; when the plug is a C20-VLOCK plug 27, the buckle on the side of the plug is engaged with the limit bayonet 19 of the socket unit 1.
[0070] It should be noted that, due to the large size of the IEC60320-C20 plug, in the embodiment of the present application, the IEC60320-C20 plug cannot be matched with the socket unit 1 with the assembly seat anti-drop buckle 3.
[0071] Figure 9a is a schematic diagram of the structure of the IEC60320-C22 plug shown in some embodiments of the present application; Figure 9b It is a schematic diagram of the matching between the socket unit and the IEC60320-C22 plug shown in some embodiments of the present application.
[0072] like Figure 9a As shown, the IEC60320-C22 plug includes a plug, namely a C22 plug 28, which does not have an anti-drop structure. Figure 9bAs shown, similar to the C14 standard plug 21, when the C22 plug 28 is inserted into the socket unit 1, the C22 plug 28 can be powered on, but cannot be snapped into the socket unit 1. When the assembly seat anti-drop buckle 3 is used, the shoulder above the C22 plug 28 can be snapped into the second buckle 9 of the assembly seat anti-drop buckle 3, thereby achieving anti-dropping.
[0073] Both of the above two engaging modes can achieve the effect of preventing falling off, and the disassembly of the above two engaging assemblies is also very convenient. It is only necessary to open the two first movable pieces 4 through the extending protrusion 7, or to press the two second movable pieces 14 toward each other through the pressing block 16.
[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include"-"comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process-method-article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process-method-article or device.
[0075] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
