As shown in FIGS. 3A and 3B and FIGS. 5A, 5B and 5C, the adapter 32 includes a top 321 and a bottom 322, wherein the top 321 is opposite to the bottom 322, and the bottom 322 can pass through the first opening 313a of the housing 31. The notch 314a or the second opening 313b of the first locking unit 314 is connected to the bottom of the accommodating portion 313 of the casing 31 (as shown in FIG. 6 and FIG. 3A , respectively). The adapter 32 also has a recessed portion 323 defined by four sidewalls 324 of the adapter 32 . The recessed portion 323 forms an opening 325 at the bottom 322 . Wherein, a plurality of side walls 324 connect the top 321 and the bottom 322, and a plurality of second engaging units 327 extend outward from the plurality of side walls 324. In this embodiment, the second engaging units 327 are Bumps are preferred and not limited thereto. In addition, the second locking unit 327 enters the guiding groove 317 through the second opening 313b, or enters the guiding groove 317 through the notch 314a of the first locking unit 314 of the first opening 313a, so that the adapter 32 is disposed in the accommodating portion 313 to complete the combination of the adapter 32 and the housing 31 . In this embodiment, the adapter 32 is roughly a square, and the second clamping unit 327 is symmetrically arranged at the four corners of the side wall 324, so the assembly direction of the adapter 32 and the housing 31 can be adjusted according to actual use needs. To be transformed, does not affect its fixed.

In the embodiment shown in FIGS. 5A , 5B and 5C , the adapter 32 may have a socket unit 328 disposed in the recessed portion 323 and capable of accommodating the first conductive unit 315 of the casing 31 . The adapter 32 further includes a second conductive unit 329, which has a first conductive end 3291, a portion of the first conductive end 3291 protrudes from the top 321 to receive power, and the second conductive end 3292 is located at the bottom of the recessed portion 323 and passes through The jack unit 328 can be connected with the first conductive unit 315 to transfer power. The insertion hole unit 328 has a plurality of extending walls 3281 connected to each other, thereby forming one or more insertion holes 3282 for accommodating the first conductive unit 315 . In this embodiment, the first conductive unit 315 is two conductive elastic pieces protruding from the bottom 313c of the accommodating portion 313; and the first conductive end 3291 of the second conductive unit 329 protruding from the top 321 is two PIN lead plug. However, in actual implementation, because the assembly and electrical connection structure of the adapter 32 and the housing 31 is modularized, the specific types of the guide plugs installed can be various types of plugs in different regions of the world.

According to the above structure, as shown in FIGS. 3A and 3B and FIGS. 5A, 5B and 5C, since the adapter 32 abuts against the slide plate 3161 through the second engaging unit 327 of the side wall 324 or directly abuts against the part of the wall surface of the side wall 324 On the sliding plate 3161 (not shown), it can limit the displacement of the adapter 32 to the second opening 313b of the housing 31; and then through the second locking unit 327 of the side wall 324, such as the aforementioned plurality of extended protrusions, And the first engaging unit 314 , such as the aforementioned flange on the edge of the first opening 313 a , engages with each other, so the displacement of the adapter 32 to the first opening 313 of the housing 31 can be restricted. Due to the incomplete engagement or positioning of the adapter 32 on the housing 31, the sliding plate 3161 will not be able to protrude from the second opening 313b smoothly, so the sliding plate unit 316 conceived according to the present invention can avoid the inaccurate assembly and positioning of the prior art. problems, and the adapter 32 can be effectively fixed on the casing 31 .

In addition, in order to adapt to the changeable assembly direction of the adapter 32 and the housing 31 , the structure of the second conductive unit 329 must be adjusted accordingly. That is, as an example, the part of the second conductive unit 329 protruding from the first conductive end 3291 of the top 321 is a two-PIN connecting plug, which is connected to the second conductive end 3292, and then connected to the shell through the second conductive end 3292. The first conductive unit 315 of the body 31 is connected to transfer power. Wherein, the second conductive end 3292 connected to each conductive terminal of the second conductive unit 329 is approximately L-shaped and symmetrically embedded in the bottom of the recessed portion 323 . In this way, when the assembly direction of the adapter 32 and the housing 31 is changed, the power adapter function thereof will not be affected.

In addition, in some embodiments, the housing 31 may further include a protection element 318, which is disposed on the bottom 313c of the accommodating portion 313 and adjacent to the first conductive unit 315, so that when the adapter 32 passes through the second opening When the protection element 313b is inserted into the guide groove 317 of the casing 31 , the protection element 318 can protect the first conductive unit 315 . In addition, the protection element 318 also has a fool-proof function, which can prevent other unsuitable adapters from being inserted into the accommodating portion 313 to damage the first conductive unit 315 . In this embodiment, the protection element 318 can be a protrusion, and is not limited thereto. In addition, in order to cooperate with the setting of the protection element 318, the bottom 322 of the adapter 32 can also form a plurality of guide rails 326 correspondingly in its second clamping unit 327 or other areas. Therefore, when the adapter 32 is inserted into the housing 31 The accommodating part 313 will not be blocked by the protection element 318 during the process, thereby also guiding and assisting the adapter 32 to move in the guide groove 317 of the housing 31 .
