The fixing device 100 includes a main board 10, a positioning assembly 20 and two fixing members 30.

[0080] like Figure 2 and Figure 3As shown, the main board 10 has an outer surface 11, an inner surface 12 and a slot 13. The slot 13 penetrates the outer surface 11 and the inner surface 12 along the reference axis L3. The slot 13 is used for the power connector 1 to be inserted along the reference axis L3 facing the inner surface 12. The slot 13 includes a main slot section 131, two side slot sections 132 and a notch 133 that are connected to each other. The two side slot sections 132 are respectively located at opposite sides of the main slot section 131 along the transverse axis L1. Each side slot section 132 has an open end 132a and a closed end 132b. Each open end 132a is connected to the main slot section 131. The groove section 131 is connected, and the periphery of each side groove section 132 has at least one positioning peripheral edge portion 132c and two connecting walls 132d. The notch 133 is located on one side of the main groove section 131 along the longitudinal axis L2 and is connected to the main groove section 131. In this embodiment, the number of at least one positioning peripheral edge portion 132c of each side groove section 132 is one, and the two positioning peripheral edges 132c of the two side groove sections 132 are relatively arranged at the two closed ends 132b in the transverse axis L1. The two connecting walls 132d are located on the periphery of each side groove section 132 along the longitudinal axis L2 and correspond to each other in the upper and lower directions. The motherboard 10 of this embodiment is the back plate of the housing of the electronic device.

[0081] like Figure 4 and Figure 6 As shown, the positioning assembly 20 includes two positioning plates 21, each positioning plate 21 includes a plate body 211, at least one tongue piece 212 and a through hole 213, the plate body 211 of each positioning plate 21 has a first plate segment 211a and a second plate segment 211b, a space S is formed between the two first plate segments 211a, the space S is for the main body 1a of the power connector 1 to pass through along the reference axis L3, each through hole 213 is located in each first plate segment 211a and corresponds to each side groove segment 132, the second plate segment 211b has at least one through hole 211b1, and the at least one through hole 211b1 corresponds to the outer surface 11 ( Figure 2Reference); In this embodiment, the number of at least one through hole 211b1 of each positioning plate 21 is one, and the number of at least one tongue piece 212 of each positioning plate 21 is one, and the tongue piece 212 is formed by stamping. The tongue piece 212 includes a bent portion 212a and a free end 212b. One side of the bent portion 212a of each tongue piece 212 is connected to a hole edge of each through hole 211b1 and extends along the reference axis L3. The other side of the bent portion 212a of each tongue piece 212 is bent toward the transverse axis L1 to form a free end 212b. A sleeve portion 214 is formed between each tongue piece 212 and each plate body 211. The sleeve portion 214 of each positioning plate 21 can be movably sleeved on the positioning peripheral edge portion 132c around each side groove section 132 along the transverse axis L1. The two free ends 212b of the two tongue pieces 212 are in the transverse axis L1. The two sleeve portions 214 of the two positioning plates 21 are opposite to each other in the horizontal axis L1, that is, the tongue pieces 212 of each positioning plate 21 correspond to the side slot sections 132 of the slot hole 13 and face the inner surface 12 of the main board 10; therefore, the slot hole 13 is limited by the positioning component 20 to form a space S between the two first plate sections 211a, so that the slot hole 13 can meet the specifications of the power connector 1 for the power connector 1 to be inserted, and the design of the movable sleeve positioning peripheral edge portion 132c of the two sleeve portions 214 can adjust the position to match the tolerance of the specifications of the power connector 1 for the power connector 1 to pass through.

[0082] like Figure 5 As shown, a height H1 of the main groove section 131 along the longitudinal axis L2 is between 31.8 mm and 32.2 mm, and a width W1 of the main groove section 131 along the transverse axis L1 is between 39.8 mm and 40.2 mm, a height H2 of the two side groove sections 132 along the longitudinal axis L2 is between 12.9 mm and 14.1 mm, a distance D1 of the centers of the two side groove sections 132 along the transverse axis L1 is between 59.8 mm and 60.2 mm, a distance D2 of the closed ends 132 b of the two side groove sections 132 along the transverse axis L1 is between 71.7 mm and 72.3 mm, a width W2 of the notch 133 along the transverse axis L1 is between 9.5 mm and 9.9 mm, and a height H3 of the notch 133 along the longitudinal axis L2 is between 7.95 mm and 8.45 mm.

[0083] Please visit again Figure 2The two fixing members 30 are respectively used to be combined with the combining holes 1b1 of the two ear portions 1b of the power connector 1, wherein each fixing member 30 includes a bolt 31 and a gasket 32, and the bolt 31 includes a head 311 and a body 312. In actual operation, each body 312 can be sequentially passed through each gasket 32, each corresponding through hole 213, each side groove section 132 and each combining hole 1b1 along the reference axis L3. The gasket 32 ​​is located between the head 311 and the plate body 211 of the corresponding positioning plate 21 to prevent the screw from being easily loosened; therefore, the power connector 1 and the positioning assembly 20 are connected in a locking manner through the two fixing members 30.

[0084] like Figures 6 to 8 As shown, first, the two tongues 212 of the two positioning plates 21 of the positioning assembly 20 are passed through the slots 13, and the two positioning plates 21 are respectively displaced from the main slot sections 131 of the corresponding slots 13 to the corresponding side slot sections 132 along the transverse axis L1, driving each tongue 212 to displace from the main slot section 131 through the open end 132a of the side slot section 132 along the transverse axis L1 to the closed end 132b of each side slot section 132 until the sleeve connection portion 214 ( Figure 4 The power connector 1 is displaced along the reference axial direction L3 toward the inner surface 12 of the motherboard 10, so that the main body 1a of the power connector 1 passes through the space S between the main slot section 131 and the two first plate sections 211a along the reference axial direction L3 and protrudes out of the outer surface 11 of the main body 1a, and the two fixing members 30 are sequentially locked into the through hole 213 of the positioning assembly 20 and the combination hole 1b1 of the power connector 1 along the reference axial direction L3 ( Figure 2 ), thereby limiting the size of the slot 13 through the positioning component 20, so that the space S between the two first plate sections 211a can meet the specifications of the power connector 1 so that the power connector 1 can be inserted into the slot 13, and then the two fixing members 30 are used to lock the positioning component 20 and the power connector 1, so that the power connector 1 is installed on the motherboard 10 and will not fall off easily, and the power connector 1 can be slightly displaced in the upward, downward, left and right directions relative to the motherboard 10. In addition, the stopper 1c of the power connector 1 passes through the notch 133 to limit the displacement of the power connector 1 in the transverse axis L1.

[0085] like Fig. 9 and Fig.10As shown, in other embodiments, the positioning component 20 can be omitted according to the specification requirements of the power connector 1'. For example, when another power connector 1' with a larger size is used, the specification of the other power connector 1' can be a 12V power supply version of the open frame standard. The distance between the two ears 1b' of the other power connector 1' is wider. The positioning component 20 can be omitted, and the main body 1a' of the other power connector 1' is directly passed through the main slot section 131 along the reference axis L3. At this time, the two ears 1b' of the other power connector 1' correspond to the two side slot sections 132, and the two fixing members 30 are passed through the two side slot sections 132 along the reference axis L3 to lock into the coupling hole 1b1' of the power connector 1'. In addition, the stopper 1c' of the power connector 1' passes through the notch 133 to limit the displacement of the power connector 1' in the transverse axis L1.

[0086] The positioning assembly 20 allows the smaller power connector 1 to be mounted on the motherboard 10. In addition, the slot 13 of the motherboard 10 can be adapted to two sizes of power connectors 1 and 1', that is, power connectors adapted to the 12V power supply and 48V power supply versions of the open rack standard.

[0087] Please refer to Figures 11 to 17 As shown, the fixing device 200 of the second preferred embodiment of the utility model has a structure substantially the same as that of the first embodiment, except that: Fig.12 and Fig.13 As shown, in this embodiment, the number of at least one positioning peripheral edge portion 132c' of each side slot section 132 on the main board 10 is two and they are respectively formed on the periphery of each connecting wall 132d in the longitudinal axis direction L2 and correspond to each other in the upper and lower directions.

[0088] In addition, the structure of each positioning plate 22 of the positioning assembly 20a of this embodiment is also different from the positioning plate 21 of the first embodiment. Fig.14 and Fig.15The number of at least one through hole 221b1 of each second plate segment 221b of each positioning plate 22 is two, the number of at least one tongue piece 222 of each positioning plate 22 is two, the two through holes 221b1 of each second plate segment 221b are arranged opposite to each other on the longitudinal axis L2, the two tongue pieces 222 of each positioning plate 22 respectively include a bent portion 222a and a free end 222b, one side of the bent portion 222a of each tongue piece 222 is connected to a hole edge of each through hole 221b1 and extends along the longitudinal axis L2, and each tongue piece 22 2 is bent toward the longitudinal axis L2 to form a free end 222b, and the two free ends 222b of each tongue piece 222 are opposite to each other on the longitudinal axis L2. At least one sleeve portion 224 is formed between each tongue piece 222 and each plate body 221. In this embodiment, the number of at least one sleeve portion 224 of each positioning plate 22 corresponds to the number of two tongue pieces 222 of each positioning plate 22, and each sleeve portion 224 can be movably sleeved on the positioning peripheral edge portion 132c' around each side groove section 132 along the longitudinal axis L2.

[0089] like Figures 15 to 17 As shown, in actual operation, the two positioning plates 22 of the positioning assembly 20a are first displaced from the main slot section 131 of the corresponding slot hole 13 to the corresponding side slot sections 132 along the transverse axis L1, so that each tongue piece 222 is displaced from the main slot section 131 to the closed end 132b of each side slot section 132 along the transverse axis L1 through the open end 132a of the side slot section 132, until the sleeve portion 224 of each positioning plate 22 sleeves each positioning peripheral portion 132c' along the longitudinal axis L2, and then the power connector 1 is moved along the reference axis L2. The main body 1a of the power connector 1 is displaced toward the inner surface 12 of the main board 10 along the reference axial direction L3, so that the main body 1a of the power connector 1 passes through the space S between the main slot section 131 and the two first plate sections 221a along the reference axial direction L3 and protrudes out of the outer surface 11 of the main body 1a, and the two fixing members 30 are sequentially locked into the through hole 223 of the positioning component 20a and the combining hole of the power connector 1 along the reference axial direction L3, thereby also achieving the purpose of limiting the size of the slot hole 13 to meet the specifications of the power connector 1 through the positioning component 20a.

[0090] Please refer to Fig.18 As shown, the fixing device 300 of the third preferred embodiment of the utility model is based on the structure of the first embodiment. The positioning component 20b also includes a bridging structure 23, and the bridging structure 23 includes a first bridging member 231 and a second bridging member 232. The first bridging member 231 and the second bridging member 232 are relatively connected to the plate body 211 of the two positioning plates 21 along the longitudinal axis L2. The two ends of the first bridging member 231 are respectively connected to the upper side of the first plate segment 211a of the two plate bodies, and the two ends of the second bridging member 232 are respectively connected to the lower side of the first plate segment 211a of the two plate bodies 211. In this embodiment, the first bridging member 231 and the second bridging member 232 form an elastic structure, which can be squeezed to make the two positioning plates 21 approach each other along the transverse axis L1.

[0091] In actual operation, the two positioning plates 21 are first squeezed simultaneously along the transverse axis L1 to generate elastic force on the first bridge member 231 and the second bridge member 232. After the positioning assembly 20b is moved into the slot 13, the two positioning plates 21 are released to restore the elastic force of the first bridge member 231 and the second bridge member 232, driving the two positioning plates 21 to move away from each other along the transverse axis L1. At the same time, the two tongues 222 are displaced from the main slot section 131 through the open end 132a of the side slot section 132 along the transverse axis L1 to the closed end 132b of each side slot section 132 until the sleeve portion 214 of each positioning plate 21 sleeves each positioning peripheral edge portion 132c along the transverse axis L1. Next, the power connector 1 is displaced along the reference axial direction L3 toward the inner surface 12 of the motherboard 10, so that the main body 1a of the power connector 1 passes through the space S between the main slot section 131 and the two first plate sections 211a along the reference axial direction L3 and protrudes out of the outer surface 11 of the main body 1a, and the two fixing members 30 are sequentially locked into the through hole 213 of the positioning component 20b and the combining hole 1b1 of the power connector 1 along the reference axial direction L3, thereby also achieving the purpose of limiting the size of the slot hole 13 to meet the specifications of the power connector 1 through the positioning component 20b.

[0092] The bridging structure 23 of this embodiment can also be applied to the positioning assembly 20 a of the second embodiment.

[0093] In summary, the fixing device of the present invention limits the size of the slot hole of the mainboard through the two positioning plates of the positioning component, so that a smaller power connector can also be installed on the mainboard. The structural changes of the positioning component are coordinated, and the socket parts of each tongue piece are socketed on the positioning peripheral edge part of the mainboard, so that the two first plates limit the size of the slot hole along the horizontal axis to form a space for the body of the smaller power connector to pass through the space.

[0094] In addition, when another power connector of a larger size is to be installed, the positioning assembly can be omitted, and the main body of the power connector can be directly passed through the main slot section along the reference axis, and the two fixing members can be passed through the two side slot sections along the reference axis to lock into the combination hole of the power connector. This can achieve the purpose of the slot hole of the mainboard being suitable for power connectors of two sizes at the same time. Therefore, the development cost of the mainboard is reduced.

[0095] The above description is only a preferred feasible embodiment of the present utility model. Any equivalent changes made by applying the specification and claims of the present utility model should be included in the patent scope of the present utility model.
