Description
Technical Field
[0001] This utility model relates to the field of sockets, and more particularly to a power converter with multiple standard sockets. Background Technology
[0002] Traditional travel sockets are widely used in various scenarios, especially to meet the power needs of travel. However, existing travel sockets have certain technical problems during use, mainly concerning the stability of the connection with wall sockets.
[0003] In many traditional socket designs, the plug slides freely inside the travel socket and is prone to slipping out when the socket is tilted. When connecting to a wall socket, in order to ensure the safe insertion of the plug, the user needs to manually push the plug handle 8 to make the plug pass through the safety door of the wall socket. This operation is often not convenient. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a power converter with multiple standard sockets, which aims to solve the problem of inconvenient operation.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a power converter with multiple standard sockets, comprising a power converter body, characterized in that the power converter body is provided with a locking rod and a locking slider disposed on the plug, the locking slider and the plug are slidably connected, and the plug is also provided with an elastic mechanism, the deformation part of the elastic mechanism abutting against the plug so that the locking slider and the locking rod are locked and engaged.
[0006] The beneficial effects of this utility model are:
[0007] This utility model uses a sliding engagement mechanism consisting of a locking slider and a plug. Under the action of the elastic engagement mechanism, the entire plug can be fixed in a specific position. Compared with the problems pointed out by the prior art, the use of the locking slider and locking rod makes it more convenient to operate the plug through the safety door, without the need to manually push the handle.
[0008] The sliding direction of the locking slider and the sliding direction of the plug are perpendicular to each other. In this embodiment, the locking slider moves along direction A and the plug moves along direction B.
[0009] The aforementioned elastic mechanism is a return spring. The locking slider has a cavity to accommodate the return spring, which extends to the front and back surfaces of the locking slider. On the area of the plug corresponding to the cavity, there is a blocking block that enters the cavity. The blocking block has a positioning post. The return spring is sleeved on the positioning post. One end of the return spring abuts against one side of the cavity, and the other end abuts against the blocking block. When engaged, the return spring is in a compressed state and pushes the locking slider towards the locking rod through its elastic force. This design method mainly reduces the use of other components. By setting up a cavity in the original volume of the locking slider, the spatial constraint effect of the return spring is better.
[0010] The locking rod is provided with a latch, and the locking slider is provided with a corresponding latch block. Under the action of the return spring, the latch block is inserted into the latch. In this embodiment, there are two latches, which are distributed on the front and rear ends of the locking rod. Specifically, this locking method can achieve better stability, and under the action of the latch, the forward and backward movement of the locking slider is restricted.
[0011] The back of the plug is provided with a sliding buckle, and the edge of the locking slider is provided with a sliding groove. The sliding buckle engages with the sliding groove, and the sliding buckle slides on the sliding groove.
[0012] The power converter body has multiple handles that push out the internal plug. The handles are connected to locking sliders. First, the handles are pushed into the power converter body. The locking slider moves along the inward direction of the handles on the socket. This movement causes the locking block to disengage from the slot.
[0013] The plug has several different specifications. Its characteristic is that it has a stop mechanism inside, which includes a slidable stop plate. The stop plate has a blocking portion that prevents the plug from extending from the power converter body and a clearance area that allows the plug to extend from the power converter body. 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, so 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 plug, and the remaining blocking portions of the stop plate are opposite to other plugs.
[0014] The stop mechanism restricts the extension of other plug types into the socket by selectively using one type. The stop plate in the stop mechanism has a sliding action. In conjunction 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. This completes the effect of blocking the extension of a single plug while preventing other plugs from freely sliding out of the socket, thus solving the inconvenience problem of existing technology.
[0015] This power converter integrates plugs of various specifications. In this embodiment, it includes three standards: American Standard, British Standard, and European Standard. Different standard 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 for different standards. The specific settings are described below according to the different standards:
[0016] US Standard:
[0017] 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.
[0018] British Standard:
[0019] 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.
[0020] European Standard:
[0021] 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.
[0022] 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 groove, and the third blocking part enters into the groove to form a stopping effect.
[0023] 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 far away from the round connector. This allows for the creation of a groove of corresponding depth on the assembly port.
[0024] The use of this utility model is illustrated by the following examples:
[0025] 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.
[0026] For the usage of other types of plugs, please refer to the above content.
[0027] 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 slot, thus creating a blocking effect.
[0028] The power converter 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.
[0029] 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.
[0030] 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

[0044] like Figure 1-13 As shown, a power converter with multiple standard sockets includes a power converter body 1. The power converter body 1 is characterized by having a locking rod 6 and a locking slider 7 disposed on the plug. The locking slider 7 is slidably connected to the plug. The plug is also provided with an elastic mechanism. The deformation part of the elastic mechanism abuts against the plug, causing the locking slider 7 to lock and engage with the locking rod 6.
[0045] The beneficial effects of this utility model are:
[0046] This utility model uses a sliding engagement mechanism consisting of a locking slider 7 and a plug. Under the action of the elastic engagement mechanism, the entire plug can be fixed in a specific position. Compared with the problems pointed out by the prior art, the use of the locking slider 7 and the locking rod 6 makes it more convenient to operate the plug through the safety door, without the need to manually push the handle 8.
[0047] The sliding direction of the locking slider 7 is perpendicular to the sliding direction of the plug. In this embodiment, the locking slider 7 moves along direction A, and the plug moves along direction B.
[0048] The aforementioned elastic mechanism is a return spring 9. The locking slider 7 has a cavity to accommodate the return spring 9. The cavity extends to the front and back surfaces of the locking slider 7. On the area of the plug corresponding to the cavity, there is a blocking block 10 that enters the cavity. The blocking block 10 has a positioning post. The return spring 9 is sleeved on the positioning post. One end of the return spring 9 abuts against one side of the cavity, and the other end abuts against the blocking block 10. When engaged, the return spring 9 is in a compressed state and pushes the locking slider 7 against the locking rod 6 through elastic force. This design method mainly reduces the use of other components. The cavity is set in the original volume of the locking slider 7, which has a better spatial constraint effect on the return spring 9.
[0049] The locking rod 6 is provided with a latch 61, and the locking slider 7 is provided with a latch 71 corresponding to the latch 61. Under the action of the return spring 9, the latch 71 is inserted into the latch 61. In this embodiment, there are two latches 61, which are distributed on the front and rear ends of the locking rod 6. Specifically, this locking method can achieve better stability. Under the action of the latch 61, the forward and backward movement of the locking slider 7 is restricted.
[0050] The back of the plug is provided with a sliding buckle 73, and the edge of the locking slider 7 is provided with a sliding groove 72. The sliding buckle 73 engages with the sliding groove 72, and the sliding buckle 73 slides on the sliding groove 72.
[0051] The power converter body 1 is provided with multiple handles 8 that push out the internal plug. The handles 8 are connected to the locking slider 7. First, the handles 8 are pushed inward into the power converter body 1. The locking slider 7 moves on the socket along the inward direction of the handles 8. This movement will cause the locking block 71 to disengage from the slot.
[0052] The plugs have multiple different specifications. The power converter body 1 is provided with multiple plugs of different specifications. The plugs are provided with a stop mechanism. The stop mechanism includes a slidable stop plate 21. The stop plate 21 has a blocking part that prevents the plug from extending out of the power converter body 1 and a clearance area that allows the plug to extend out of the power converter body 1. The clearance area and the blocking part are adjacent to each other. There are multiple clearance areas and blocking parts corresponding to the number of plugs. The blocking part is provided with a guide surface 21a, so that the contact between the current plug and the blocking part causes the stop plate 21 to slide, so that the clearance area corresponds to the plug. The remaining blocking parts of the stop plate 21 are opposite to other plugs.
[0053] 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.
[0054] 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:
[0055] US Standard:
[0056] 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.
[0057] British Standard:
[0058] 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.
[0059] European Standard:
[0060] 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.
[0061] 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 groove, and the third blocking part 203 enters into the groove to form a stopping effect.
[0062] 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 stroke, 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 a groove of corresponding depth to be set on the assembly port.
[0063] The use of this utility model is illustrated by the following examples:
[0064] 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.
[0065] For the usage of other types of plugs, please refer to the above content.
[0066] 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 inserted into the slot, forming a blocking effect.
[0067] The power converter 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.
[0068] 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.
[0069] 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.
[0070] 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 by those skilled in the art to the technical solutions of the present utility model 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.
