Description
Technical Field
[0001] This utility model relates to the field of travel sockets, and more particularly to an adapter socket suitable for multi-country power converters. Background Technology
[0002] A travel adapter, also known as a travel converter or plug adapter, is a device used to adapt to different types of sockets and voltages when traveling to different countries or regions. It helps you use your electrical appliances, such as mobile phones, laptops, and electric toothbrushes, abroad by ensuring your devices can be correctly connected to the power outlets in your destination.
[0003] However, when using these travel sockets with a single plug, other plugs can easily extend out. When using these sockets, it's inevitable that some sockets will be located close to the floor. When a person squats down, the socket may tilt. When the socket tilts, all the plugs inside will slide out. At this time, it is necessary to push the unrelated plugs back into the socket, which is very inconvenient. Utility Model Content
[0004] To address the aforementioned issues, this invention provides an adapter socket suitable for multi-country power converters, which has an internal stop mechanism to prevent plugs of other specifications from automatically sliding out, thereby resolving the technical problems existing in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adapter socket suitable for multi-country power converters, comprising a body, wherein multiple plugs of different specifications are provided within the body, characterized in that a stop mechanism is provided within the plug, the stop mechanism comprising a slidable stop plate, the stop plate having a blocking portion that prevents the plug from extending from the body and a clearance area that allows the plug to extend from the body, the clearance area and the blocking portion being adjacent to each other, the clearance area and the blocking portion having multiple clearance areas corresponding to the number of plugs, the blocking portion having a guide surface, such that the contact between the current plug and the blocking portion causes the stop plate to slide, so that the clearance area corresponds to the aforementioned plug, and the remaining blocking portions of the stop plate are opposite to other plugs.
[0006] The beneficial effects of this utility model are:
[0007] The stop mechanism used in this utility model restricts the extension of other plugs in the socket by selectively using one of them. The stop plate in the stop mechanism has a sliding action. Combined with the guide surface on the blocking part, the contact between the plug and the guide surface causes the stop plate to move along the direction of the guide surface. At this time, the blocking part switches from contacting the plug to a state of mutual offset, and the plug corresponds to the avoidance area on the stop plate. Thus, the effect of a single plug extending while other plugs are stopped is achieved, preventing other plugs from freely sliding out of the socket and solving the problem of inconvenience in the use of the prior art.
[0008] This adapter socket integrates plugs of various specifications. In this embodiment, it includes three standards: American Standard, British Standard, and European Standard. Different standards of plugs have different electrical connectors, including circular electrical connectors and rectangular electrical connectors, as well as vertical and inclined applications for the rectangular connectors. In this invention, there is only one stop plate. Therefore, the stop plate has different settings for the blocking parts and clearance areas of different standards. The specific settings are described below according to the different standards:
[0009] US Standard:
[0010] The American standard plug uses two rectangular connecting pieces. In this invention, a corresponding first blocking part is formed on the edge of the stop plate, and a corresponding first clearance area is located outside the first blocking part. In this embodiment, the first blocking part is formed on the upper edge of the stop plate, and the first clearance area is the space above the first blocking part. In order to save certain costs, only one first blocking part is used, and the first blocking part is used in conjunction with one of the rectangular connecting pieces.
[0011] British Standard:
[0012] In this embodiment, the British standard plug uses three rectangular connecting pieces. The corresponding second blocking part is formed on the side edge of the stop plate. The second blocking part is composed of two stop blocks, which are spaced apart. The space between the two stop blocks is the second clearance area. This design is mainly because the electrical connecting piece for connecting the neutral and live wires in the British standard plug is located in the middle part of the socket area. Whether the stop plate slides up or down, the second blocking part can block the electrical connecting piece.
[0013] European Standard:
[0014] The European standard plug includes an assembly block and two circular connectors located on the assembly block. The third stop is located on the lower edge of the stop plate, and the third clearance area is the space below the third stop.
[0015] It should be noted that the European standard round connector is smooth, and the third blocking part has a guide surface. Therefore, the stopping effect on the round connector is not ideal. In order to ensure this stopping effect, the assembly block has a bayonet. The third blocking part enters into the bayonet to form a stopping effect.
[0016] The European standard plug is located below the British standard plug. Meanwhile, the round connector and the American standard electrical connector are close to each other in the longitudinal dimension. Therefore, in order to allow the stop plate to have sufficient sliding travel, the position of the third blocking part is offset from the position of the first blocking part and is also far away from the round connector. This allows for the setting of a corresponding depth of the bayonet on the assembly port.
[0017] The use of this utility model is illustrated by the following examples:
[0018] When using an American standard plug, the electrical connecting piece in the plug applies pressure to the first blocking part. The first blocking part has a guide surface, which is inclined. At this time, the thrust applied to the guide surface causes the stop plate to slide longitudinally. In this embodiment, the stop plate moves downward. At this time, the area opposite the first blocking part and the electrical connecting piece gradually shrinks until they are completely misaligned. At this time, the electrical connecting piece switches from a state opposite to the first blocking part to a state opposite to the first clearance area.
[0019] For the usage of other types of plugs, please refer to the above content.
[0020] At the same time, the downward movement of the stop plate causes the stop block in the British standard and the third blocking part in the European standard to move downward. In other words, the stop block blocks the electrical connector in the European standard, while the third blocking part is inserted into the bayonet, thus creating a blocking effect.
[0021] The main body has a mounting plate with a hook part, and the stop plate has an opening with a step corresponding to the hook part inside the opening. After the hook part passes through the opening, it engages with the step. At the same time, the hook part and the step are in a sliding relationship. Therefore, the stop plate can slide longitudinally on the mounting plate.
[0022] Considering the smoothness of the stop plate's movement, a guide strip is provided on the mounting plate, and a guide groove is provided on the stop plate. The guide groove is fitted onto the guide strip, and the guide strip and the inner wall of the guide groove are in contact with each other. Under the constraint of the guide strip and the guide groove, the movement of the stop plate is quite smooth.
[0023] The mounting plate also includes a spring seat and a spring. The spring seat is located above the stop plate, and one end of the spring is connected to the spring seat, while the other end is connected to a connecting seat on the edge of the stop plate. The purpose of the spring is to provide a reset effect, helping the stop plate return to its original position. Attached Figure Description

[0031] Please see Figure 1-7 As shown, an adapter socket suitable for multi-country power converters includes a body 1, which contains multiple plugs of different specifications. The plugs are characterized by having a stop mechanism, which includes a slidable stop plate 21. The stop plate 21 has a blocking portion that prevents the plug from extending from the body 1 and a clearance area that allows the plug to extend from the body 1. The clearance area and the blocking portion are adjacent to each other, and there are multiple clearance areas and blocking portions corresponding to the number of plugs. The blocking portion has a guide surface 21a, which causes the stop plate 21 to slide when the current plug contacts the blocking portion, so that the clearance area corresponds to the plug, and the remaining blocking portions of the stop plate 21 are opposite to other plugs.
[0032] The stop mechanism used in this utility model restricts the extension of other plugs in the socket by selectively using one of them. The stop plate 21 set in the stop mechanism has a sliding action. Combined with the guide surface 21a on the blocking part, the contact between the plug and the guide surface 21a causes the stop plate 21 to move along the direction of the guide surface 21a. At this time, the blocking part switches from contacting the plug to a state of mutual offset, and the plug corresponds to the avoidance area on the stop plate 21. Thus, the effect of a single plug extending while other plugs are stopped is achieved, preventing other plugs from freely sliding out of the socket and solving the problem of inconvenience in the use of the prior art.
[0033] This adapter socket integrates plugs of various specifications. In this embodiment, it includes three standards: American Standard, British Standard, and European Standard. Different standards of plugs have different electrical connectors, including circular electrical connectors and rectangular electrical connectors, as well as vertical and inclined applications for the rectangular connectors. In this invention, there is only one stop plate 21. Therefore, the stop plate 21 has different settings for the blocking parts and clearance areas of different standards. The specific settings are described below according to the different standards:
[0034] US Standard:
[0035] The American standard plug uses two rectangular connecting pieces. In this invention, a corresponding first blocking part 200 is formed on the edge of the stop plate 21, and a corresponding first clearance area is located outside the first blocking part 200. In this embodiment, the first blocking part 200 is formed on the upper edge of the stop plate 21, and the first clearance area is the space above the first blocking part 200. In order to save certain costs, only one first blocking part 200 is used. The first blocking part 200 is used in conjunction with one of the rectangular connecting pieces.
[0036] British Standard:
[0037] In this embodiment, the British standard plug uses three rectangular connecting pieces. The corresponding second blocking part is formed on the side edge of the stop plate 21. The second blocking part is composed of two stop blocks 201, which are spaced apart. The space between the two stop blocks 201 is the second clearance area 202. This design is mainly because the electrical connecting piece for connecting the neutral and live wires in the British standard plug is located in the middle part of the socket area. Whether the stop plate 21 slides up or down, the second blocking part can block the electrical connecting piece.
[0038] European Standard:
[0039] The European standard plug includes an assembly block and two circular connectors located on the assembly block. The third blocking part 203 is located on the lower edge of the stop plate 21, and the third clearance area is the space below the third blocking part 203.
[0040] It should be noted that the European standard round connector is smooth, and the third blocking part 203 is provided with a guide surface. Therefore, the stopping effect on the round connector is not ideal. In order to ensure this stopping effect, the assembly block is provided with a bayonet. The third blocking part 203 enters into the bayonet to form a stopping effect.
[0041] The European standard plug is located below the British standard plug. Meanwhile, the round connector and the American standard electrical connector are close to each other in the longitudinal dimension. Therefore, in order to allow the stop plate 21 to have sufficient sliding travel, the position of the third blocking part 203 is offset from the position of the first blocking part 200 and is also far away from the round connector. This allows for the setting of a corresponding depth of the bayonet on the assembly port.
[0042] The use of this utility model is illustrated by the following examples:
[0043] When using an American standard plug, the electrical connecting piece in the plug applies pressure to the first blocking part 200. The first blocking part 200 has a guide surface 21a, which is inclined. At this time, the thrust applied to the guide surface 21a causes the stop plate 21 to slide longitudinally. In this embodiment, the stop plate 21 moves downward. At this time, the area opposite to the first blocking part 200 and the electrical connecting piece gradually shrinks until they are completely misaligned. At this time, the electrical connecting piece switches from a state opposite to the first blocking part 200 to a state opposite to the first clearance area.
[0044] For the usage of other types of plugs, please refer to the above content.
[0045] At the same time, the downward movement of the stop plate 21 causes the stop block 201 in the British standard and the third blocking part 203 in the European standard to move downward. That is to say, the stop block 201 blocks the electrical connector in the European standard, while the third blocking part 203 is embedded in the bayonet, forming a blocking effect.
[0046] The main body 1 is provided with a mounting plate 3, and the mounting plate 3 is provided with a hook part 31. The stop plate 21 is provided with an opening 201-1, and the opening 201-1 is provided with a step 201-2 corresponding to the hook part 31. After the hook part 31 passes through the opening 201-1, it forms a locking effect with the step 201-2. At the same time, the hook part 31 and the step 201-2 are in a sliding relationship. Therefore, the stop plate 21 can slide longitudinally on the mounting plate 3.
[0047] Considering the degree of movement of the stop plate 21, the mounting plate 3 is provided with a guide strip 31, and the stop plate 21 is provided with a guide groove 201-3. The guide groove 201-3 is fitted onto the guide strip 31, and the inner wall of the guide strip 31 and the inner surface of the guide groove 201-3 are in contact with each other. Under the constraint of the guide strip 31 and the guide groove 201-3, the movement of the stop plate 21 is quite smooth.
[0048] The mounting plate 3 is also equipped with a spring seat 4 and a spring 5. The spring seat 4 is located above the stop plate 21. One end of the spring 5 is connected to the spring seat 4, and the other end is connected to the connecting seat 6 on the edge of the stop plate 21. The purpose of setting the spring 5 is to provide a reset effect, helping the stop plate 21 to return to its original position.
[0049] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
