[0002] A plug is a connector that connects to a power socket to power electronic devices. The specifications of the plug vary according to the regulations of different countries and regions. Therefore, in order to be compatible with sockets in different countries and regions, conversion sockets with different pins are created.

[0003] However, when using sockets in some countries, it is necessary not only to match the shape of the pins, but also to match the shape of the insulating seat connected to the pins. For example, the Korean standard plug uses a round insulating seat, while the European standard plug uses a hexagonal insulating seat.

[0004] However, the plug insulating seat is relatively large and therefore difficult to be integrated into the same plug assembly. Utility Model Content

[0032] The purpose, features and advantages of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, top, bottom, side...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0036] In addition, the descriptions involving "first", "second", etc. in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0037] In view of the technical defects existing in the related art, this embodiment provides a plug assembly 100. Figure 1 and Figure 2 As shown, the plug assembly 100 of this embodiment includes a first insulating seat 110 having a receiving groove 111 and a second insulating seat 120 embedded in the receiving groove 111. A plug pin 130 is provided on the side of the bottom wall of the second insulating seat 120 facing away from the receiving groove 111, which is used to connect to an external power socket. In this embodiment, the first insulating seat 110 and the second insulating seat 120 can move relative to each other, so that the second insulating seat 120 can extend outward from the first insulating seat 110.

[0038] Exemplarily, a slide rail is formed on the side wall of the receiving groove 111 and extends toward the notch of the receiving groove 111, and a slide groove that slidably cooperates with the slide rail is provided on the peripheral side of the second insulating seat 120, so that the first insulating seat 110 and the second insulating seat 120 can slide relative to each other. It is understandable that as long as the relative sliding between the first insulating seat 110 and the second insulating seat 120 can be achieved, a corresponding sliding connection structure can also be adopted according to actual needs, and examples are not given here one by one.

[0039] Since the plug assembly 100 of this embodiment embeds the smaller insulating seat in the larger insulating seat, the two can move relative to each other, thereby integrating the insulating seats of two plugs that can share the pins 130 but have different specifications. For example, both the Korean plug and the European plug use cylindrical pins 130, and the size difference between them is small. Therefore, the Korean insulating seat is used as the first insulating seat 110, and a receiving groove 111 that is shaped like the European insulating seat is formed. Then, the insulating seat of the European plug is embedded in the receiving groove 111 as the second insulating seat 120, so that the insulating seats of the two plugs with different specifications can be integrated.

[0040] When it is necessary to connect to a Korean standard socket, since the Korean standard socket must not only match the shape of the pin 130, but also match the shape of the insulating seat, Figure 1 As shown, by putting the first insulating seat 110 on the second insulating seat 120, the plugging requirements of the Korean standard socket can be met. When it is necessary to connect with the European standard socket, the European standard socket also requires that the shape of the pin 130 matches the shape of the insulating seat, so Figure 2 As shown, the first insulating seat 110 and the second insulating seat 120 are relatively moved, so that the second insulating seat 120 is extended outward from the first insulating seat 110, so that the second insulating seat 120 and the plug pin 130 can be plugged into the European standard socket.

[0041] The plug assembly 100 of this embodiment integrates the insulating seats of two plugs that can share the pins 130 but have different specifications, thereby realizing the plug assembly 100 that can be applied to sockets of different specifications, thereby improving the compatibility of the plug assembly 100.

[0042] Furthermore, the plug assembly 100 of this embodiment can integrate pins 130 of different sizes in addition to the insulating seat. Figures 3 to 5 As shown, the second insulating seat 120 has an accommodating channel 121 that penetrates the second insulating seat 120 , a portion of the pin 130 is inserted into the accommodating channel 121 , and a connecting portion 122 is formed between the pin 130 and the inner wall of the accommodating channel 121 , and the connecting portion 122 is formed along the length direction of the pin 130 .

[0043] A conductive sleeve 140 is connected to the bottom wall of the receiving groove 111, and a clearance groove 141 corresponding to the connection portion 122 is provided on the conductive sleeve 140. The conductive sleeve 140 can be inserted into the receiving channel 121 from the side of the second insulating seat 120 facing away from the plug pin 130. The conductive sleeve 140 is provided with the clearance groove 141, so the conductive sleeve 140 can avoid the connection portion 122 during the process of passing through the receiving channel 121, and can be slidably sleeved with the plug pin 130 after completely passing through the receiving channel 121. Since the conductive sleeve 140 can be made of conductive materials such as copper, silver, and nickel, the conductive sleeve 140 forms an electrical connection with the plug pin 130 after the conductive sleeve 140 is slidably sleeved with the plug pin 130.

[0044] Since the conductive sleeve 140 is connected to the first insulating seat 110, as the first insulating seat 110 and the second insulating seat 120 move relative to each other, the conductive sleeve 140 also moves relative to the first insulating seat 110, the second insulating seat 120 and the pin 130, so that the conductive sleeve 140 can be connected to or separated from the pin 130 as needed, so that the power terminal of the plug assembly 100 of this embodiment can match the pin 130 holes of different sizes.

[0045] For example, the first insulating seat 110 is a Korean standard insulating seat, and the second insulating seat 120 is a European standard insulating seat. The pin 130 is configured as a European standard pin 130 with a diameter of 4 mm, and the conductive sleeve 140 is configured as a cylindrical sleeve with a thickness of 0.4 mm. Figure 1 As shown, when the second insulating seat 120 is embedded in the accommodating groove 111 of the first insulating seat 110, the conductive sleeve 140 is also sleeved on the pin 130, so that the power terminal of the entire plug assembly 100 constitutes a Korean standard pin 130 with a diameter of 4.8 mm. Therefore, when the plug assembly 100 of this embodiment is mated with a Korean standard socket, the shape of the insulating seat and the size of the power terminal are completely consistent with the Korean standard socket, which further improves the mating stability.

[0046] like Figure 2 As shown, when the second insulating seat 120 extends outward from the first insulating seat 110, the conductive sleeve 140 also detaches from the pin 130, so that the entire plug assembly 100 is converted into a European plug. In this state, when the plug assembly 100 of this embodiment is mated with a European socket, the shape of the insulating seat and the size of the electrical terminal are completely consistent with the European socket, which further improves the mating stability.

[0047] Further, continue to refer to Figure 6 and Figure 7 As shown, the plug assembly 100 of this embodiment further includes a conductive column 150 and a power board 160. The first insulating seat 110 has a through hole 112 connected to the lumen of the conductive sleeve 140. One end of the conductive column 150 is connected to the plug pin 130 through the through hole 112. The power board 160 is electrically connected to the end of the conductive column 150 away from the plug pin 130, so that the power board 160 is electrically connected to the plug pin 130 through the conductive column 150. Since the conductive column 150 is connected to the plug pin 130 through the through hole 112 provided on the first insulating seat 110, when the first insulating seat 110 moves relative to the second insulating seat 120, the conductive column 150 acts as a slide rail for the first insulating seat 110, thereby improving the activity stability between the first insulating seat 110 and the second insulating seat 120. Among them, the conductive column 150 and the plug pin 130 can be integrally formed or separately provided according to actual needs.

[0048] Exemplarily, the power board 160 is used to conduct electricity between the copper sheet of the socket and the pin 130 of the plug assembly 100 of this embodiment. When the socket adopts the plug assembly 100 of this embodiment, the electric energy is sequentially transmitted to the copper sheet of the socket through the pin 130, the conductive column 150, and the power board 160. The power board 160 can be installed in the housing 210 of the socket, but is not limited thereto.

[0049] Furthermore, in order to accurately locate the relative position between the first insulating seat 110 and the second insulating seat 120, in the present embodiment, a locking device is provided on the side of the bottom wall of the first insulating seat 110 facing away from the accommodating groove 111, and the locking device can form a locking connection with the conductive column 150. When the first insulating seat 110 and the second insulating seat 120 move relative to each other to an appropriate position, the locking device locks with the conductive column 150, thereby locking the relative position between the first insulating seat 110 and the second insulating seat 120.

[0050] Specifically, combined Figures 6 to 8As shown, the locking device includes a locking tongue 171 located on the side of the bottom wall of the first insulating seat 110 facing away from the receiving groove 111 and a sliding rod 172 connected to the locking tongue 171, and the sliding rod 172 is slidably connected to the first insulating seat 110. The free end of the sliding rod 172 extends outward from the edge of the first insulating seat 110, so that the locking tongue 171 can be pushed by the sliding rod 172. The conductive column 150 is provided with a first locking groove 151 and a second locking groove 152 spaced apart along the length direction of the conductive column 150, and the locking tongue 171 can be inserted into or removed from the first locking groove 151 or the second locking groove 152 under the push of the sliding rod 172.

[0051] like Figure 6 As shown, the second insulating seat 120 is embedded in the receiving groove 111 of the first insulating seat 110, and the conductive sleeve 140 is also sleeved on the plug pin 130. The locking tongue 171 is embedded in the second locking groove 152, thereby limiting the relative movement between the first insulating seat 110 and the second insulating seat 120, so that the plug assembly 100 can stably maintain the Korean standard plug.

[0052] like Figure 7 As shown, the sliding rod 172 is pushed in a direction close to the first insulating seat 110, so that the locking tongue 171 is disengaged from the second locking groove 152. At this time, since the relative movement between the first insulating seat 110 and the second insulating seat 120 is not hindered, the first insulating seat 110 can be pushed upward by the sliding rod 172, so that the second insulating seat 120 extends outward from the first insulating seat 110, and the conductive sleeve 140 is also separated from the pin 130.

[0053] like Figure 8 As shown, the sliding rod 172 is pushed away from the first insulating seat 110 to make the locking tongue 171 escape from the first locking groove 151. At this time, the relative movement between the first insulating seat 110 and the second insulating seat 120 is restricted again, so the first insulating seat 110 cannot be pushed downward by the sliding rod 172, so that the plug assembly 100 can stably maintain the European standard plug.

[0054] Furthermore, if Figure 6 and Figure 8 As shown, the locking device further includes a stopper 173 and an elastic member 174 located on one side of the bottom wall of the first insulating seat 110 facing away from the receiving groove 111. The stopper 173 is arranged opposite to the lock tongue 171, and the elastic member 174 is located between the stopper 173 and the lock tongue 171. The two ends of the elastic member 174 abut against the stopper 173 and the lock tongue 171 respectively, and the elastic member 174 is used to reset the lock tongue 171, thereby facilitating the locking operation of the locking device.

[0055] In some embodiments, a conversion socket 200 using the plug assembly 100 of the above embodiment is also provided. A sliding groove for operating the sliding rod 172 is provided on the housing 210 of the conversion socket 200. Figure 9a As shown, when the conversion socket 200 of this embodiment is in the first use state, the first insulating seat 110 is retracted into the housing 210, so that it can be plugged into the corresponding socket through the second insulating seat 120 and the plug pin 130 located outside the housing 210. Figure 9b As shown, when the conversion socket 200 of this embodiment is in the second use state, the first insulating seat 110 is sleeved on the second insulating seat 120 located outside the housing 210, so that it can be plugged into another corresponding socket through the first insulating seat 110 and the plug pin 130. Among them, the power board 160 of the plug assembly 100 is installed on the inner wall of the housing 210 and is electrically connected to the copper sheet of the socket of the conversion socket 200.

[0056] In summary, the conversion socket 200 of this embodiment can draw power from two sockets of different specifications, thereby improving the compatibility of the conversion socket 200 .

[0057] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
