Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a travel conversion socket panel. Background Art

[0002] Since plug specifications vary from country to country, in order to reduce the number of charging plugs you need to carry when traveling to multiple countries, you can carry a power converter to convert between different plugs to adapt to different power sockets in different countries. The socket panel of the power converter that is embedded with multiple plugs generally has jacks for national and European standard plugs, American plugs, Italian plugs, and British plugs. Since national and European standard plugs, American plugs, Italian plugs, and British plugs all have three prongs distributed in a triangle, they need to be inserted according to the distribution of the jacks. If the distribution of the various jacks is unreasonable, when converting different plugs, the triangularly distributed prongs may need to be flipped 180 degrees before they can be inserted into the corresponding jack, which is inconvenient to use. Utility Model Content

[0003] The purpose of the present utility model is to provide a travel conversion socket panel to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is: a travel conversion socket panel, including an upper cover, the upper cover is provided with a first jack, a second jack, a third jack and a fourth jack, the first jack and the second jack are distributed side by side along a first straight line, and the two third jacks are symmetrically distributed on both sides of the second jack along the first straight line, the first plug and the third jack can be adapted to insert national standard and European standard plugs, the second plug and the fourth jack can be adapted to insert Italian standard and American standard plugs, and the first plug and the fourth jack can be adapted to insert British standard plugs.

[0005] This technical solution has at least the following beneficial effects: after the national standard and European standard plugs, Italian standard and British standard plugs, and American standard plugs are inserted into the corresponding jacks, the distribution directions of the sharp angles of the triangles corresponding to the three pins are all corresponding, so that the insertion direction can be quickly identified, so as to facilitate the rapid replacement and adaptation of plugs of different specifications. In addition, the positions of the jacks are compactly and reasonably distributed, which facilitates the construction of the internal structure of the power converter and reduces space.

[0006] As a further improvement to the above technical solution, the invention further comprises a lower cover, wherein the lower cover is slidably mounted with a first safety door and two second safety doors. First inclined surfaces are provided on either side of the first safety door at positions corresponding to the two fourth insertion holes. A first elastic member is installed between the first safety door and the lower cover to maintain the first inclined surfaces in alignment with the fourth insertion holes. Two second safety doors are respectively provided at positions corresponding to the two third insertion holes. The second safety doors are provided at positions corresponding to the third insertion holes. A second elastic member is installed between the second safety door and the lower cover to maintain the second inclined surfaces in alignment with the third insertion holes. When a corresponding plug is inserted into the fourth insertion hole, the plug contacts the first inclined surfaces, thereby pushing the first safety door out of the position corresponding to the fourth insertion hole, thereby allowing the corresponding plug to enter. When the corresponding plug is inserted into the third insertion hole, the plug contacts the second inclined surfaces, thereby pushing the second safety door out of the position corresponding to the third insertion hole, thereby allowing the corresponding plug to enter. Therefore, the provision of the first and second safety doors improves user safety.

[0007] As a further improvement to the above technical solution, the sliding direction of the second safety door is perpendicular to the length direction of the third jack, and the second inclined surface is inclined along the sliding direction of the second safety door. This allows the second safety door to be pushed more easily when the corresponding plug contacts the second inclined surface, facilitating use.

[0008] As a further improvement to the above technical solution, a guide block is provided on the side of the second safety door away from the second inclined surface, and the guide block is slidably mounted on the lower cover. The guide block can improve the stability of the second safety door sliding relative to the lower cover, thereby improving the reliability of the second safety door.

[0009] As a further improvement of the above technical solution, the lower cover is provided with a first groove for the first safety door to be embedded and slid, and the lower cover is provided with a second groove for the second safety door to be embedded and slid.

[0010] As a further improvement of the above technical solution, the first groove is provided with a balancing guide bar, and the first safety door is provided with a guide groove for the balancing guide bar to be embedded and slide, thereby improving the sliding stability of the first safety door.

[0011] As a further improvement to the above technical solution, the first groove is provided with a limiting groove at each position corresponding to the two fourth insertion holes. When the first safety door is positioned corresponding to the fourth insertion hole, it can swing relative to the balancing guide bar at a preset angle so that one side of the first safety door can be embedded in the corresponding limiting groove. When a foreign object is inserted into only one of the two fourth insertion holes, the first safety door on that side will tilt at a preset angle and embed into the limiting groove on the corresponding side. The sidewall of the limiting groove restricts the sliding movement of the first safety door, preventing the first safety door from being pushed and blocking further insertion of foreign objects, thereby effectively preventing foreign objects from being inserted on one side.

[0012] As a further improvement to the above technical solution, the lower cover is provided with a first slot, and the upper cover is provided with a first hook that can be inserted into the first slot. The upper cover is placed on the lower cover, and the first hook is inserted into the first slot, thereby firmly connecting the upper cover and the lower cover and facilitating assembly.

[0013] As a further improvement to the above technical solution, the housing further comprises a clamping block mounted on its inner circumference, a buckle provided on the circumference of the lower cover for being fitted over the clamping block, and a third inclined surface provided on the clamping block in the direction in which the buckle is fitted. When the lower cover is placed on the housing, the clamping block is guided into the buckle by the third inclined surface, thereby firmly attaching the lower cover to the housing for easier assembly.

[0014] As a further improvement to the above technical solution, the edge of the upper cover is provided with a convex edge ring, and the lower cover is provided with an annular groove for the convex edge ring to fit into, thereby improving the fit between the edge of the upper cover and the lower cover and preventing the edge of the upper cover from warping.

[0026] Reference Figure 1-2The travel adapter panel includes an upper cover 100, a lower cover 200 and a shell 600. The upper cover 100 is in the shape of a flat plate, and a first socket 110 and a second socket 120 are provided in the upper cover 100. A first straight line 150 is fictitiously provided in the middle of the upper cover 100, and the first socket 110 and the second socket 120 are arranged side by side along the direction of the first straight line 150 at the position where the first straight line 150 is located. It should be noted that in other embodiments, the position of the first straight line 150 may not be located in the middle, but may be located to one side. The first socket 110 includes a first square hole 111 and a first circular hole 112 connected to each other by a side wall close to each other. The first square hole 111 is located on a side away from the second socket 120, that is, the first circular hole 112 is located on a side close to the second socket 120. Second insertion hole 120 includes a second square hole 121 and a second oblong hole 122 connected by adjacent side walls. The long axis of second oblong hole 122 coincides with first line 150. Both corners of second square hole 121 near the side of second oblong hole 122 are arc-shaped. Second square hole 121 is located near first insertion hole 110, meaning second oblong hole 122 is located away from first insertion hole 110.

[0027] The upper cover 100 also has a third and fourth sockets 130 and 140 on either side. Two third sockets 130 are provided, symmetrically located on either side of the second socket 120 along a first straight line 150. Specifically, the lateral position of the third sockets 130 corresponds to the junction of the second square hole 121 and the second oblong hole 122. The cross-section of the third sockets 130 is an elongated square. The two third sockets 130 are arranged close to each other and tilted at the end away from the first socket 110.

[0028] Two fourth insertion holes 140 are provided, symmetrically arranged on either side of the second insertion hole 120 along a first straight line 150. Specifically, the fourth insertion hole 140 includes a fourth elongated hole 141, a fourth circular hole 142, and a fourth square hole 143, arranged in a horizontally parallel relationship. The fourth elongated hole 141 and the fourth circular hole 142 are interconnected on a side wall adjacent to each other, while the fourth circular hole 142 and the fourth square hole 143 are interconnected on a side wall adjacent to each other. The fourth elongated hole 141 is located closest to the end of the second elongated hole 122 that is distal from the second square hole.

[0029] The second oblong hole 122 and the two fourth round holes 142 can be used to insert Italian-standard plugs. The second square hole 121 and the two fourth long strip holes 141 can be used to insert American-standard plugs. The first square hole 111 and the two third jacks 130 can be used to insert Chinese and European-standard plugs. The first round hole 112 and the two fourth square holes 143 can be used to insert British-standard plugs. When the Italian-standard plug, the American-standard plug, the Chinese and European-standard plugs, and the British-standard plug are in use, the distribution directions of the sharp angles of the triangles corresponding to the three pins are all corresponding, which can facilitate quick identification of the insertion direction, so as to facilitate quick replacement and adaptation of plugs of different specifications. In addition, the positions of the jacks are compactly and reasonably distributed, which facilitates the construction of the internal structure of the power converter and reduces space.

[0030] Reference Figure 2-5 A first groove 330 is defined at the top of the lower cover 200. A first safety door 300 is slidably mounted within the first groove 330, sliding along the first straight line 150 within the first groove 330. One end of the sliding range of the first safety door 300 within the first groove 330 corresponds to the positions of the two fourth receptacles 140. A first elastic member 320 is positioned at the other end of the sliding range. The first elastic member 320 is a first coil spring. Two mounting posts are positioned side by side on one side of the first safety door 300. One end of each first coil spring is embedded in a corresponding mounting post, while the other end abuts against the inner wall of the first groove 330. This allows the elastic force of the first coil spring to maintain the first safety door 300 in its position corresponding to the fourth receptacles 140. A first inclined surface 310 is provided on the top of the first safety door 300. When the pin is inserted into the fourth socket 140, it will come into contact with the first inclined surface 310 of the first safety door 300. A certain amount of force needs to be applied to push the first safety door 300 to overcome the elastic force of the first coil spring and move so that the pin can pass through the first safety door 300 smoothly.

[0031] A balancing guide bar 340 is positioned in the middle of the first groove 330, parallel to the first line 150. The top of the balancing guide bar 340 is curved, and a guide groove 350 is defined in the center of the bottom of the first safety door 300, into which the balancing guide bar 340 engages. This ensures greater stability and reliability when the first safety door 300 slides within the first groove 330. Restriction grooves 360 are defined at two locations on the bottom wall of the first groove 330, corresponding to the fourth insertion holes 140 on either side. The bottom walls of the restriction grooves 360 each include a through-hole for the pin to pass through. When the first safety door 300 is positioned in the position corresponding to the fourth insertion holes 140, it can swing relative to the balancing guide bar 340 within the first groove 330 by a predetermined angle. After the balancing guide bar 340 has swung by the predetermined angle, one side of the balancing guide bar 340 engages in the restriction groove 360, preventing it from moving against the force of the first coil spring. Therefore, if a foreign object is inserted into the fourth socket 140 on only one side and contacts one side of the first safety door 300, the first safety door 300 will swing due to unbalanced force, and one side of the first safety door 300 will be embedded in the limiting groove 360 and cannot be pushed, thereby preventing the foreign object from passing through the first safety door 300, thereby playing a role of further safety protection.

[0032] The top of the lower cover 200 also includes two second grooves 440. A guide block 430 is slidably mounted within each of the second grooves 440. The guide block 430 is integrally connected to the second safety door 400. A clearance groove is defined on the side of the guide block 430 facing away from the second safety door 400. A second elastic member 420, comprising a second coil spring, is mounted between the sidewalls of the clearance groove and the sidewalls of the second groove 440. The elastic force of the second coil spring maintains the second safety door 400 in its position corresponding to the third insertion hole 130. At this point, the guide block 430 is positioned at one end of the second groove 440, i.e., at one end of its range of motion. It will be appreciated that the outer wall of the guide block 430 abuts against and guides the inner wall of the second groove 440, improving the guiding stability of the guide block 430 and the second safety door 400. Furthermore, the second coil spring disposed within the clearance groove of the guide block 430 makes the structure more compact and improves space utilization.

[0033] A second inclined surface 410 is provided on the top of the second safety door 400. When the pin is inserted into the third socket 130, it will conflict with the second inclined surface 410 of the second safety door 400, so that the second safety door 400 can overcome the elastic force of the second threaded spring and move, so that the pin can pass through the second safety door 400 smoothly. A through hole for the pin to pass through is provided at the bottom of the second groove 440 to allow the pin to pass through the second safety door 400.

[0034] The sliding direction of the guide block 430 is perpendicular to the length of the third insertion hole 130. That is, the sliding directions of the two guide blocks 430 on either side are inclined, and when sliding against the elastic force of the second coil spring, the guide blocks 430 slide away from each other. The second inclined surface is tilted along the sliding direction of the guide block 430. Even if a correspondingly shaped pin contacts the second inclined surface, the longer side of the pin will fit snugly against it, pushing the second safety door 400 and the guide block 430 to slide. This increases the contact area between the pin and the second inclined surface and improves contact stability.

[0035] It should be noted that the width of the second safety door 400 is greater than the width of the guide block 430, so that the guide block 430 and the second safety door 400 form an L-shaped structure. The second groove 440 has a channel on the side adjacent to the first groove 330 that is connected to the first groove 330. The second safety door 400 is disposed within the channel and can slide within the channel. In other embodiments, the first elastic member 320 and the second elastic member 420 can also be elastic sheets.

[0036] It should be noted that a support block is also installed at the bottom of the lower cover 200, and a U-shaped positioning frame is protruding from the top of the support block. The U-shaped positioning frame passes through the top of the lower cover 200, and a U-shaped groove that is adapted to the U-shaped positioning frame is provided on one side of the first safety door 300. When the first safety door 300 corresponds to the position of the fourth jack 140, the U-shaped positioning frame is embedded in the U-shaped groove, thereby limiting one end of the sliding range of the first safety door 300.

[0037] In order to facilitate the installation of the upper cover 100, a plurality of first hooks 510 are provided on the bottom of the upper cover 100, and a plurality of first slots 500 corresponding to the positions of the first hooks 510 are opened on the lower cover 200. When the upper cover 100 is covered on the top of the lower cover 200, the first hooks 510 can be correspondingly engaged in the first slots 500, so that the upper cover 100 can be installed on the top of the lower cover 200, and the top surface of the upper cover 100 is set flush with the top edge of the lower cover 200, so that the overall aesthetics is better. A raised flange ring 700 is provided at the bottom edge of the upper cover 100, and an annular groove 710 is opened at the top edge of the lower cover 200. The flange ring 700 and the annular groove 710 are adapted to each other, so that when the upper cover 100 is installed on the lower cover 200, the flange ring 700 can be embedded in the annular groove 710 to improve the tightness between the upper cover 100 and the lower cover 200, thereby preventing the upper cover 100 from warping.

[0038] The inner sidewall of the housing 600 is provided with a block 610, located near the diamond edge. A third inclined surface 611 is provided at the top of the block 610, and a retaining ring 620 is provided at the position corresponding to the block 610 on the lower cover 200. When the lower cover 200 is assembled with the housing 600, the block 610 can be guided by the third inclined surface 611 to fit into the retaining ring 620, thereby stabilizing the connection between the lower cover 200 and the housing 600. In addition, a column is provided inside the housing 600, and the lower cover 200 is fixed to the column via screws, thereby further stabilizing the connection between the housing 600 and the lower cover 200.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
