Description

Technical Field

[0001] This application relates to the field of mechanical connection technology, and in particular to a terminal housing connection structure. Background Technology

[0002] In the field of electronic device housing connection technology, with the continuous advancement of technology, electronic devices are becoming increasingly powerful and their application scenarios are becoming more and more widespread. Electronic devices play a vital role in people's daily lives and work. This development has placed higher demands on the manufacturing and maintenance of electronic devices, especially in terms of housing connections. Not only must the stability of the connection be guaranteed, but the ease of installation and disassembly must also be considered to adapt to the needs of rapid iteration and maintenance.

[0003] Existing fixing methods have significant drawbacks. While traditional screw and bolt fixing methods provide secure fastening, they require tools during installation and disassembly, making the process cumbersome and time-consuming. Existing snap-fit ​​structures are prone to loosening or damage during frequent disassembly and installation, leading to decreased reliability and failing to adequately meet the demands of rapid installation and disassembly, as well as the miniaturization and modularization of electronic devices. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a terminal housing connection structure. By adopting a modular design, the upper and lower connecting shells and side sealing plates can be quickly assembled. The first and second stops enhance the sealing performance, and the snap-fit ​​and locking buckle ensure a secure installation. It is suitable for secure installation in externally set mounting holes, thus improving stability.

[0005] This application is achieved through the following technical solution:

[0006] A terminal housing connection structure includes an upper connecting shell, a lower connecting shell, and a side sealing plate. The upper and lower connecting shells are combined to form an assembly with an open side. The assembly is fixed to the side sealing plate. The inner wall of the assembly is provided with a limiting groove for fixing a PCB board. The mating edges of the upper and lower connecting shells are provided with a first stop. The mating edges of the upper and lower connecting shells and the side sealing plate are provided with a second stop. The side sealing plate is provided with a snap-fit ​​plate, which is provided with a snap-fit ​​component for fixing the upper or lower connecting shell. The upper or lower connecting shell is provided with a snap-fit ​​interface adapted to the snap-fit ​​component. A right-angle slide groove is provided on the side corner of the assembly perpendicular to the side sealing plate, and a locking buckle is slidably connected to the right-angle slide groove. The locking buckle cooperates with a positioning shoulder provided on the side sealing plate to fix the side sealing plate and the assembly together in an externally set mounting hole.

[0007] By adopting the above technical solution, the upper connecting shell and the lower connecting shell are combined into an assembly with an open side and fixed to the side sealing plate, which facilitates overall assembly; the limiting groove on the inner wall of the assembly can fix the PCB board and ensure its installation position; the first stop and the second stop can improve the sealing and stability of the upper connecting shell and the lower connecting shell, and the upper connecting shell and the lower connecting shell and the side sealing plate; the snap-fit ​​on the snap-fit ​​plate is adapted to the snap-fit ​​interface of the upper connecting shell or the lower connecting shell, which facilitates the fixing of the two; the cooperation between the right-angle slide and the locking buckle, and the cooperation between the locking buckle and the positioning shoulder, can fix the side sealing plate and the assembly in the externally set mounting holes, ensuring the stable installation of the terminal shell connection structure.

[0008] Optionally, the locking buckle includes a vertically arranged sliding part, and the bottom of the sliding part is provided with a lower wing plate arranged at a right angle.

[0009] By adopting the above technical solution, the locking buckle is provided with a vertical sliding part and a bottom right-angled lower wing plate, which provides a specific structural form and operating part for the locking buckle. This helps it slide on the right-angle slide groove and better cooperate with the positioning shoulder, enhancing the function of fixing the side sealing plate and the assembly to the external mounting hole.

[0010] Optionally, the side of the sliding part away from the right-angle groove is provided with an anti-slip groove, and the anti-slip grooves are arranged sequentially from top to bottom along the middle of the sliding part.

[0011] By adopting the above technical solution, when operating the locking buckle, the anti-slip groove can increase the friction between the hand and the sliding part, so that people can push the locking buckle to slide on the right-angle groove more stably and easily, which facilitates the operation of fixing the side sealing plate and the assembly in the external mounting hole.

[0012] Optionally, the top of the sliding part is provided with a bent handle.

[0013] By adopting the above technical solution, the bending handle facilitates the pushing and pulling operation of the locking buckle, thereby making the locking and unlocking actions more convenient and facilitating the installation and disassembly of the entire terminal housing connection structure.

[0014] Optionally, the right-angle slide includes guide strips arranged vertically on both sides of the assembly near the corner; the sliding part has an upper wing plate arranged at a right angle in the middle, and the upper wing plate has an abutment part adapted to the guide strip.

[0015] By adopting the above technical solution, guide strips are set on both sides of the assembly near the corner. In conjunction with the abutting part of the upper wing plate of the sliding part, the locking buckle can slide more stably and accurately on the right-angle slide groove, ensuring that when the locking buckle cooperates with the positioning shoulder, the side sealing plate and the assembly can be accurately fixed in the externally set mounting hole.

[0016] Optionally, the lower wing plate is arranged at an angle so that a deformation space is formed between the lower wing plate and the externally set mounting hole.

[0017] By adopting the above technical solution, the deformation space formed by the obliquely arranged lower wing plate can provide a certain buffer and adjustment margin for the installation process, reduce the risk of damage caused by installation errors, and enable the terminal housing connection structure to be installed more smoothly in the externally set mounting holes.

[0018] Optionally, the edge of the right-angle groove is provided with a ratchet portion, and the abutting portion is provided with reverse teeth adapted to the ratchet portion.

[0019] By adopting the above technical solution, a ratchet part is provided on the edge of the right-angle slide groove and a matching reverse tooth is provided on the abutment part, which can prevent the locking buckle from accidentally sliding in the right-angle slide groove and improve the stability of the terminal housing connection structure fixed in the external mounting hole.

[0020] Optionally, the first stop is provided with a first extension, the first extension is provided with a first positioning block, and the upper connecting shell or the lower connecting shell is provided with a first positioning hole adapted to the first positioning block; the second stop is provided with a second extension, the second extension is provided with a second positioning block, and the upper connecting shell, the lower connecting shell or the side sealing plate is provided with a second positioning hole adapted to the second positioning block.

[0021] By adopting the above technical solution, the assembly accuracy and stability between the upper connecting shell, the lower connecting shell and the side sealing plate can be further improved by using the first positioning block on the first extension to cooperate with the first positioning hole on the upper connecting shell or the lower connecting shell, and the second positioning block on the second extension to cooperate with the second positioning hole on the upper connecting shell, the lower connecting shell or the side sealing plate.

[0022] Optionally, an auxiliary positioning hole is provided between the side sealing plate and the upper connecting shell and the lower connecting shell, and a positioning buckle is inserted into the auxiliary positioning hole.

[0023] By adopting the above technical solution, the stability and accuracy of the connection between the side sealing plate and the upper and lower connecting shells can be enhanced by using auxiliary positioning holes and positioning buckles.

[0024] Optionally, the upper end of the right-angle slide is provided with an inclined guide surface; a protective cover is fitted on the side sealing plate, and the mating surface of the protective cover and the side sealing plate is provided with an opening adapted to the positioning shoulder; the locking buckle cooperates with the protective cover to fix the side sealing plate and the assembly together in the externally set mounting hole.

[0025] By adopting the above technical solution, the inclined guide surface at the upper end of the right-angle slide groove facilitates the smooth sliding of the locking buckle, the protective cover can protect the side sealing plate, and its opening adapted to the positioning shoulder allows the locking buckle to cooperate with it, so as to achieve a more stable fixation of the side sealing plate and the assembly in the external mounting hole.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application uses a combination of multiple structures to ensure the stability of the upper and lower connecting shells, improve sealing and structural strength, and achieve rapid assembly and disassembly as well as overall stable installation.

[0028] 2. This application, through the engagement of the ratchet and the counter-tooth, can limit the sliding of the locking buckle, enhance positioning stability, prevent the assembly from loosening, and improve the overall fixing reliability.

[0029] 3. This application enhances the connection positioning accuracy, improves the sealing performance and structural stability between components, and prevents relative displacement by cooperating with the extensions of the first and second stops and the positioning blocks and positioning holes.

[0044] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Example 1

[0046] Reference Figures 1-3This application discloses a terminal housing connection structure, including an upper connecting shell 21, a lower connecting shell 22, and a side sealing plate 3. The upper connecting shell 21 and the lower connecting shell 22 are combined to form an assembly 2 with an open side structure. The assembly 2 is fixed to the side sealing plate 3. The inner wall of the assembly 2 is provided with a limiting groove 23 for fixing a PCB board 4. The mating edges of the upper connecting shell 21 and the lower connecting shell 22 are provided with a first stop 211. The mating edges of the upper connecting shell 21 and the lower connecting shell 22 with the side sealing plate 3 are provided with a second stop 31. The plate 3 is provided with a snap-fit ​​plate 32, and the snap-fit ​​plate 32 is provided with a snap-fit ​​part 321 for fixing the upper connecting shell 21 or the lower connecting shell 22. The upper connecting shell 21 or the lower connecting shell 22 is provided with a snap-fit ​​interface 221 that is adapted to the snap-fit ​​part 321. The side corner of the assembly 2 perpendicular to the side sealing plate 3 is provided with a right-angle slide groove 24, and a locking buckle 25 is slidably connected to the right-angle slide groove 24. The locking buckle 25 cooperates with the positioning shoulder 33 provided on the side sealing plate 3, which can fix the side sealing plate 3 and the assembly 2 together in the externally set mounting hole 1.

[0047] Specifically, refer to Figures 4-6 The right-angle slide groove 24 includes guide strips 241 arranged vertically on both sides of the assembly 2 near the corner; the sliding part 251 has an upper wing plate 2513 arranged at a right angle in the middle, and the upper wing plate 2513 has an abutment part 2514 adapted to the guide strips 241. The guide strips 241 can be metal strips or plastic strips, and are fixed to the assembly 2 by welding, gluing or integral molding. When the sliding part 251 slides in the right-angle slide groove 24, the abutment part 2514 slides along the guide strips 241, playing a guiding role. The edge of the right-angle slide groove 24 has a ratchet part 242, and the abutment part 2514 has a countertooth 2515 adapted to the ratchet part 242. When the locking buckle 25 slides to the appropriate position, the countertooth 2515 cooperates with the ratchet part 242, which can prevent the locking buckle 25 from sliding randomly and increase the stability of locking.

[0048] Reference Figures 6-7 The locking buckle 25 includes a vertically arranged sliding part 251, with a lower wing plate 2511 arranged at a right angle at the bottom of the sliding part 251. A bending handle 2512 is provided at the top of the sliding part 251. The bending handle 2512 facilitates the operator to grasp and push the locking buckle 25 to slide. The lower wing plate 2511 is arranged at an angle to create a deformation space between the lower wing plate 2511 and the externally set mounting hole 1. When the locking buckle 25 slides downward to fix the assembly 2 and the side sealing plate 3 in the mounting hole 1, the lower wing plate 2511 undergoes a certain elastic deformation to better adapt to the size and shape of the mounting hole 1, ensuring a tight connection.

[0049] Reference Figure 7 The sliding part 251 is provided with an anti-slip groove 252 on the side away from the right-angle groove 24. The anti-slip grooves 252 are arranged sequentially from top to bottom along the middle of the sliding part 251.

[0050] Reference Figures 8-9 The first stop 211 is provided with a first extension 2111, and a first positioning block 2112 is provided on the first extension 2111. The upper connecting shell 21 or the lower connecting shell 22 is provided with a first positioning hole 212 that is adapted to the first positioning block 2112.

[0051] Reference Figure 10 The upper end of the right-angle slide groove 24 is provided with an inclined guide surface 243; a protective cover 35 is fitted on the side sealing plate 3, and the mating surface of the protective cover 35 and the side sealing plate 3 is provided with an opening 351 that matches the positioning shoulder 33. The locking buckle 25 cooperates with the protective cover 35 to fix the side sealing plate 3 and the assembly 2 together in the externally set mounting hole 1. The inclined guide surface 243 can guide the locking buckle 25 to enter the right-angle slide groove 24 more smoothly, which facilitates the installation operation; the protective cover 35 can be made of plastic, which serves to protect the side sealing plate 3 and the internal structure.

[0052] Reference Figure 11 The second stop 31 is provided with a second extension 311, and a second positioning block 3111 is provided on the second extension 311. The upper connecting shell 21, the lower connecting shell 22 or the side sealing plate 3 are provided with a second positioning hole 213 that is adapted to the second positioning block 3111.

[0053] The implementation principle of this embodiment is as follows: This terminal housing connection structure solves the problems of stability and ease of installation and disassembly in existing terminal housing connection methods through a combination of multiple connection methods. The cooperation between the snap-fit ​​component 321 and the snap-fit ​​interface 221 achieves a quick initial connection. The first stop 211 and the second stop 31 enhance the positioning and sealing effect. The limiting groove 23 can stably fix the PCB board 4. The cooperation between the right-angle slide groove 24 and the locking buckle 25, as well as the setting of the positioning shoulder 33, achieve a stable connection with the external mounting hole 1. At the same time, the anti-slip groove 252 and the bending handle 2512 facilitate operation. The entire structure not only ensures the connection strength, but also facilitates installation and disassembly, which is beneficial to the maintenance and upgrading of the equipment. Compared with the traditional connection method, it has been greatly improved.

[0054] Example 2

[0055] Reference Figures 12-13The difference between this embodiment and Embodiment 1 is that an auxiliary positioning hole 34 is provided between the side sealing plate 3 and the upper connecting shell 21 and the lower connecting shell 22, allowing communication between them. A positioning buckle 341 is inserted into the auxiliary positioning hole 34. The size and depth of the auxiliary positioning hole 34 need to be precisely set according to the size of the positioning buckle 341 to ensure that the positioning buckle 341 can be firmly inserted. The positioning buckle 341 can be in a π-shaped structure or other shapes, and its material can be metal, such as stainless steel, which has high strength and corrosion resistance. After being inserted into the auxiliary positioning hole 34, the positioning buckle 341 can further enhance the connection accuracy and stability between the side sealing plate 3 and the assembly 2, making the terminal shell connection structure more reliable and reducing the problem of connection loosening caused by vibration.

[0056] The implementation principle of this embodiment is as follows: by setting auxiliary positioning holes 34 between the side sealing plate 3 and the upper connecting shell 21 and the lower connecting shell 22 and inserting positioning buckles 341, the deficiencies of the original structure in connection accuracy and stability are made up for, the overall performance of the terminal shell connection structure is further enhanced, and the reliability of the terminal equipment in various environments is improved. This is an effective optimization of the existing connection structure.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
