DETAILED DESCRIPTION

[0026] The following will be combined with the attached Figure 1 To Attachment Figure 6 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that if there are directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and rear. Figure 1 The specific Figure 1 The left and right directions are the length directions, Figure 1 The direction perpendicular to its length is the height direction. Figure 1 The up and down directions are the width directions. If a particular posture changes, the directional indication will also change accordingly.

[0028] During the assembly process of the expansion dock in the prior art, the first plug lacks the guidance of a guide component when being inserted into an opening at one end of the accommodating cavity, which causes the first plug to be easily misaligned when inserted into the accommodating cavity, resulting in invalid assembly and affecting assembly efficiency.

[0029] Therefore, the utility model provides a docking station, such as Figure 1 As shown, the expansion dock of the utility model includes a shell 10, which is rectangular. The shell 10 has a first side 103, a second side 104 and two side walls. The two sides of the shell 10 and the two side walls together form an inner cavity 101. The inner cavity 101 is connected to the outside through a through groove 102. The inner cavity 101 of the shell 10 can also be equipped with a PCB board, and the PCB board can be placed in the inner cavity 101 through the through groove 102. The expansion dock also includes a plug 20, which is used to be placed in the through groove 102 to close the inner cavity 101.

[0030] Further, such as Figure 2As shown, the through groove 102 penetrates the side walls on both sides of the shell 10 in the width direction; the two sides and the outward direction of the through groove 102 are open, that is, the through groove 102 has a notch 1021 open to the outside, and U-shaped notches 1022 on the side walls on both sides in the width direction of the shell 10, the cross-section of the through groove 102 is C-shaped, and the through groove 102 is connected to the inner cavity 101 in the inward direction.

[0031] Therefore, the inner cavity 101 disposed inside the housing 10 can also be connected to the outside through the through slot 102. The through slot 102 is provided with a restraining portion 105 at both ends in the width direction. Figure 2 In the illustrated embodiment, the restraining portion 105 is U-shaped or semicircular and is provided on the side wall of the shell 10 ; in another embodiment, the restraining portion 105 may also be a raised block provided on the side wall of the shell 10 and higher than the inner surface of the side wall.

[0032] The restraining portion 105 mentioned above is used to contact the abutting portion 2021 on the plug 20 to guide the plug 20 into the through groove 102 .

[0033] Further, such as Figure 3 As shown, the plug 20 is in the shape of an elongated strip in the middle and bent at both ends. The plug 20 comprises an outer layer portion 201 and an assembly portion 202 from the outside to the inside. Both ends of the outer layer portion 201 have a bent extension portion 2012 extending from the outside to the inside, and the bent extension portion 2012 is arranged opposite to the assembly portion 202.

[0034] Specific as Figure 3 As shown, the outer layer 201 is bent and connected with bent extension parts 2012 at both ends in the width direction, and the bent extension parts 2012 just cover the U-shaped notch 1022 in the through groove 102 mentioned above when assembled on the shell 10. The outer layer 201 is also provided with a plurality of different types of plug holes, which are recessed inward from the surface of the outer layer 201 and pass through the assembly part 202 to communicate with the inner cavity 101 of the shell 10, so that the inner cavity 101 can also be connected with the outside.

[0035] Furthermore, the outer layer 201 is connected to an assembly portion 202 on the inner side. When the plug 20 is assembled in the through groove 102, the assembly portion 202 is covered in the through groove 102. In order to fix the assembly portion 202 in the through groove 102 so as to fix the plug 20 at the open portion of the housing 10 and prevent the plug 20 from moving upward in the housing 10, a buckle portion 2022 is provided on the assembly portion 202; the buckle portion 2022 is buckled and connected to the inner wall of the housing 10.

[0036] Specific as Figure 3 As shown, the longitudinal section of the snap-in portion 2022 is shaped like a "J". There are multiple snap-in portions 2022, which are arranged at intervals along the width direction of the assembly portion 202. The snap-in portions 2022 arranged on both sides of the assembly portion 20 in the width direction are arranged back to back with each other.

[0037] When the plug 20 is assembled into the housing 10, Figure 3 As shown, the snap portions 2022 on both sides of the assembly portion 202 in the width direction are in contact with the inner wall of the shell 10. Under the squeezing of the inner wall of the shell 10, the ends of the snap portions 2022 will move toward the middle of the assembly portion 202. After the plug 20 is stably placed in the through groove 102, the snap portions 2022 rebound and contact toward the inner wall of the shell 10. Through this design, the plug 20 is further fixed in the through groove 102 of the shell 10.

[0038] However, in order to ensure that the assembling portion 202 can be accurately, quickly and effectively placed in the through-slot 102 during the assembling process of the assembling portion 202 and the through-slot 102 , the assembling portion 202 further has an abutting portion 2021 .

[0039] More specific Figure 3 As shown, the abutment portion 2021 is disposed at both ends of the assembly portion 202 in the width direction, forming an L-shaped layout with the assembly portion 202. Specifically, the abutment portion 2021 has a first connecting surface 2023 and a second connecting surface 2024, and the first connecting surface 2023 is bent and connected with the second connecting surface 2024.

[0040] The first connection surface 2023 of the abutting portion 2021 abuts against the inner wall of the housing 10 , and the second connection surface 2024 of the abutting portion 2021 is in contact and connected with the restraining portion 105 .

[0041] Specifically, when assembling the expansion dock, the PCB board is first placed in the inner cavity 101, and then the abutment portion 2021 is abutted against the constraint portion 105 to achieve contact and connection between the second connection surface 2024 of the abutment portion 2021 and the inner side surface of the constraint portion 105. During assembly, the second connection surface 2024 of the abutment portion 2021 and the constraint portion 105 always maintain front-to-face contact. With the contact surface as a reference, the plug 20 can rotate around the reference point to rotate and guide the plug 20 into the through groove 102, thereby achieving the PCB board being enclosed inside the inner cavity 101.

[0042] It should be noted that this step can not only help the plug 20 to align with the slot hole inserted into the through slot 102, so as to correctly guide the plug 20 into the through slot 102. After the plug 20 is fixed in the notch 1021 of the through slot 102, the contact between the first connecting surface 2023 and the inner wall surface of the housing 10 can further consolidate the assembly and fixation of the plug 20 on the housing 10.

[0043] However, the abutment portion 2021 on the plug 20 may also have multiple, such as Figure 4 As shown, the abutting portions located in the height direction of the plug 20 do not cross each other and are arranged in parallel and perpendicular to the assembly portion 202 .

[0044] Furthermore, there is a space area B in the middle of the two abutting portions 2021 located at the same height direction, and the space area is used to accommodate the PCB board. When the plug 20 is fixedly mounted on the shell 10, the PCB board inside the shell 10 can be inserted into the space area B so that the PCB board will not move inside the shell 10.

[0045] like Figure 5 In another embodiment shown, the cross-sections of the two abutting portions 2021 located in the same width direction are shaped like a "concave" character. In this embodiment, the two abutting portions 2021 located in the same height direction are connected to each other and are not independent entities, but are shaped like a "concave" character. There is also a space area B above the connection between the two abutting portions 2021. The space area B can be used to clamp the PCB board to prevent the PCB board from moving inside the housing 10. In this embodiment, this design is conducive to improving the stability of the abutting portion 2021, preventing the abutting portion 2021 from bending during the guiding process, which affects the function of accurately guiding the plug 20 into the through groove 102.

[0046] It should be noted that the height of the abutment portion 2021 is higher than the surface of the assembly portion 202 and higher than the bent extension portion 2012. This design is conducive to ensuring that the abutment portion 2021 will not be blocked by the bent extension portion 2012 when abutting against the constraint portion 105, thereby avoiding affecting the effective contact between the abutment portion 2021 and the constraint portion 105.

[0047] Furthermore, the back edge of the abutting portion 2021 is connected to the bent extension portion 2012 mentioned above. It can be understood that the bending portion of the bent extension portion 2012 is connected to the abutting portion 2021 to form a thicker contact end.

[0048] Specific as Figures 4 to 5 As shown, there is a gap A between the abutting portion 2021 and the bent extension portion 2012. With this design, when the plug 20 needs to be detached from the housing 10, the bent extension portion 2012 can be pinched and a force can be applied to the bent extension portion 2012, so that the bent extension portion 2012 moves toward the abutting portion 2021. It can be understood that under the pressure of the force, the gap A will become smaller, so the bent extension portion 2012 will move toward the abutting portion 2021, indirectly pushing the first connection surface 2023 of the abutting portion 2021 to break away from the contact with the inner side wall surface of the housing 10, and the second connection surface 2024 of the abutting portion 2021 to break away from the fitting contact with the constraint portion 105, so that the plug 20 can be detached from the housing 10.

[0049] In addition, since the bending extension part 2012 is easily broken under the action of frequent pinching and pressing, connecting the bending part of the bending extension part 2012 with the abutment part 2021 to form a thicker contact end is beneficial to extending the service life of the bending extension part 2012 during the bending process.

[0050] However, when the bent extension 2012 is assembled on the housing 10 along with the plug 20, the bent extension 2012 is just at the end of the length direction of the housing 10, that is, the bent extension 2012 is just located on the top surface of the U-shaped notch 1022 of the through slot 102. At this time, the outer surface of the bent extension 2012 is flush with the outer surface of the side wall of the housing 10, so that the junction of the bent extension 2012 and the U-shaped notch 1022 forms a smooth transition area.

[0051] Further Figure 6As shown, the longitudinal section of the shape slot 1022 is U-shaped or semicircular. The shape slot 1022 can also be any other shape as long as it can match the shape of the bent extension portion 2012 located therein.

[0052] When the shape of the notch 1022 matches the shape of the bent extension portion 2012 , it is convenient for an operator to pinch the bent extension portion 2012 from the side of the shell 10 to disengage the plug 20 from the through slot 102 on the shell 10 .

[0053] In addition to the flat transition area formed at the junction of the bent extension portion 2012 and the shaped notch 1022 in the plug 20 described above, a flat transition area is also formed at the junction of the outer surface of the plug 20 and the front end surface of the housing 10 .

[0054] like Figure 1 As shown, the specific connection between the assembly portion 202 and the outer layer portion 201 also has a flange 203; the inner wall of the shell 10 has a step 106 near the opening, and the inner wall of the through groove 102 has a step 106 along the width direction near the notch 1021, and the step 106 is slightly higher than the inner surface of the shell 10, and the flange 203 abuts against the step 106.

[0055] When the plug 20 is assembled in the through groove 102, the lower surface of the flange 203 contacts the upper surface of the step 106, and the step 106 can prevent the plug 20 from moving toward the inner cavity 101 of the shell 10; the distance between the step 106 and the open end of the through groove 102 is equal to the thickness of the flange 203, so that after the lower surface of the flange 203 is completely in contact with the upper surface of the step 106, the outer surface of the outer layer 201 of the plug 20 is flush with the top surface of the side wall in the width direction of the shell 10, that is, the connection between the outer layer 201 and the top surface of the side wall in the width direction of the shell 10 forms a smooth transition area.

[0056] To sum up, a docking station adopting the technical solution of the utility model has an abutment portion 2021 on the plug 20, which can guide the plug 20 to be accurately installed into the through groove 102 on the shell 10, thereby overcoming the problem in the prior art that misalignment may occur when assembling the plug 20 on the shell 10. This solution effectively improves the assembly efficiency.

[0057] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
