[0001] The utility model relates to the technical field of plug conversion devices, in particular to a travel converter. Background Art

[0002] As we all know, socket standards in different countries are not completely unified. If you want to travel to different countries, you need to configure the corresponding plugs in that country to power the electronic devices you carry with you. For this reason, travel converters that can be applied to socket standards in different countries have emerged.

[0003] In order to improve the safety performance of the travel converter, a fuse is provided in the travel converter. When the current reaches a threshold value, the fuse will melt and disconnect the electrical connection between the pin assembly and the plug assembly, thereby forming a protective effect.

[0004] In the related art, the fuse is inserted into the travel converter through a mounting bracket. However, the mounting bracket of the related art is an independent component and can be completely separated from the travel converter when the fuse is replaced, thereby causing the risk of losing the mounting bracket.

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.

[0038] 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.

[0039] In view of the technical defects existing in the related art, this embodiment provides a travel adapter. Figures 1 to 3 As shown, the travel converter of this embodiment includes a housing and a fuse assembly.

[0040] The housing includes a container 101 with an open surface and a first cover plate 102 for sealing the open surface of the container 101. The container 101 is surrounded by a plurality of side walls, and one of the side walls of the container 101 is configured with a through hole 112. Exemplarily, the container 101 is a rectangular container, the through hole 112 is opened on the bottom wall of the rectangular container, and the first cover plate 102 is used to seal the open surface of the rectangular container.

[0041] Specific reference Figure 2 and Figure 3 As shown, the fuse assembly includes a mounting frame 120 and a fuse A disposed on the mounting frame 120. The mounting frame 120 is slidably plugged into the receiving box 101 through the through hole 112, so that the fuse A is inserted into the housing.

[0042] Further integration Figures 4 to 6 As shown, in this embodiment, a stopper 125 is protruded from one end of the mounting frame 120 located in the receiving box 101. The stopper 125 can abut against the inner side of the side wall provided with the through hole 112 when the mounting frame 120 is pulled out of the receiving box 101, preventing the mounting frame 120 from being separated from the housing, so as to prevent the mounting frame 120 from being lost.

[0043] Furthermore, the mounting frame 120 of the present embodiment includes two support rods 121 that are opposite to each other and spaced apart, a first support seat 122 for connecting one end of the two support rods 121 that are adjacent to each other, and a second support seat 123 for connecting the other end of the two support rods 121 that are adjacent to each other. The surfaces facing each other between the first support seat 122 and the second support seat 123 and the surfaces facing each other between the two support rods 121 are combined to form a mounting groove for accommodating the fuse A, so that the fuse A can be easily inserted into the housing and contacted with the conductive terminals of other components.

[0044] Optionally, in order to improve the assembly stability of the fuse A, as Figure 4 As shown, the two support rods 121 are respectively provided with elastic lugs 1211 , and the elastic lugs 1211 are used to limit the fuse A installed in the installation slot, thereby preventing the fuse A from being separated from the installation frame 120 .

[0045] Exemplarily, the limiting portion 125 is protruding from the side of the first support seat 122. When the mounting bracket 120 is plugged into the housing, the mounting bracket 120 needs to be plugged into the through hole 112 from the inside of the receiving box 101. At this time, the second supporting seat 123 is inserted toward the through hole 112, so that the first supporting seat 122 protruding with the limiting portion 125 is located in the receiving box 101. When the mounting bracket 120 is pulled out, the limiting portion 125 is abutted against the periphery of the through hole 112 to prevent the mounting bracket 120 from being separated from the housing. Of course, the limiting portion 125 can also be protruding from the side of the second supporting seat 123. At this time, the first supporting seat 122 needs to be inserted toward the through hole 112.

[0046] Further, in order to facilitate the detent mounting bracket 120, as Figure 4 As shown, the mounting frame 120 of this embodiment further includes a buckle 124. Exemplarily, the limit portion 125 is protruding from the first support seat 122, and the buckle 124 is connected to the side of the second support seat 123 facing away from the first support seat 122. At least a portion of the buckle 124 abuts against the outer side of the side wall of the receiving box 101 having the through hole 112, so that the user can buckle the mounting frame 120 and pull it out.

[0047] Preferably, the buckle member 124 is provided with a first buckle arm 141, and the second support seat 123 is provided with a first buckle hole 142 matching the first buckle arm 141. The buckle member 124 and the second support seat 123 are detachably connected through the first buckle arm 141 and the first buckle hole 142 to facilitate the assembly of the buckle member 124. Of course, according to actual design requirements, the first buckle arm 141 can also be provided on the second support seat 123, and the first buckle hole 142 is provided on the buckle member 124, which is not limited here.

[0048] It is understandable that, as a travel converter, the housing box 101 of this embodiment is also provided with a pin assembly and a plug assembly. The pin assembly extends the pins outside the housing under the operation of the user, and the pins can be connected to an external power socket and used to draw electricity. The plug assembly is used to receive the plug of the electrical device to supply power to the electrical device.

[0049] Among them, Figure 7 As shown, the pin assembly has a first conductive terminal 151, and the plug assembly has a second conductive terminal 152. When the mounting frame 120 is inserted into the receiving box 101, the first conductive terminal 151 and the second conductive terminal 152 are respectively located on opposite sides of the mounting slot in the plugging direction of the mounting frame 120. The first conductive terminal 151 abuts against one end of the fuse A through the mounting slot, and the second conductive terminal 152 abuts against the other end of the fuse A through the mounting slot, thereby forming an electrical connection between the pin assembly and the plug assembly through the fuse A, so that the electrical device can draw power from the external power socket through the travel adapter of this embodiment.

[0050] Optionally, in order to improve the flatness of the outer surface of the shell, as Figure 3 As shown, a groove 111 is arranged outside the side wall of the receiving box 101 provided with a through hole 112. The through hole 112 penetrates the bottom of the groove 111, so that the mounting bracket 120 is slidably inserted into the bottom of the groove 111. The travel converter also includes a second cover plate 160 for sealing the groove 111. Since the protruding structures such as the buckle 124 connected to the mounting bracket 120 are located in the groove 111, and the groove 111 is sealed by the second cover plate 160, it is beneficial to improve the flatness of the outer surface of the shell.

[0051] Furthermore, a second snap arm 161 is protruded on one side of the second cover plate 160 facing the bottom of the groove 111, and a second snap hole 113 matching the second snap arm 161 is provided on the bottom of the groove 111. In order to facilitate the buckling of the second cover plate 160, a buckle position is provided on the edge of the groove 111 or the edge of the second cover plate 160. A flip connection can be formed between the second cover plate 160 and the shell, and for this purpose, a rotating shaft is provided on the second cover plate 160, and an axial hole matching the rotating shaft is provided on the groove wall of the groove 111. Of course, the setting positions of the rotating shaft and the axial hole can also be interchanged, which is not limited here. Of course, in another embodiment, Figure 8 As shown, the second cover plate 160 may also be provided as an independent component.

[0052] Furthermore, when the fuse is blown, in order to quickly replace a new fuse, a storage slot 114 adjacent to the via hole 112 is provided at the bottom of the groove 111. The storage slot 114 is used to store a spare fuse B, so that when the currently used fuse A is blown, the spare fuse B can be quickly replaced, thereby improving the user experience.
