Description

Technical Field

[0001] This application relates to the field of circuit board assembly technology, and in particular to circuit board enclosures. Background Technology

[0002] In the field of electronic equipment manufacturing and application, circuit boards (PCBs), as one of the core components, have always been a focus of industry attention due to the design and use of their related components. With the rapid development of electronic technology, various electronic devices are constantly being innovated and their functions are becoming increasingly powerful, leading to higher complexity and integration levels in PCBs. As a crucial structure protecting the PCB, the performance of the PCB enclosure directly affects its stability and lifespan. A high-quality PCB enclosure can effectively prevent external factors from interfering with and damaging the PCB, improving the reliability and safety of electronic equipment, and is of great significance to promoting the development of the electronics industry.

[0003] Traditional circuit board enclosures are typically assembled using methods such as welding, riveting, or injection molding. Welding ensures a strong connection between components, guaranteeing the enclosure's integrity and airtightness. However, once welded, it becomes difficult to repair or replace the internal circuit boards, making the process arduous and prone to damage. Riveting, while offering some ease of disassembly compared to welding, requires specialized tools, is cumbersome, and repeated disassembly can loosen the riveted joints, affecting the enclosure's stability. Injection-molded circuit board enclosures offer a compact structure and good protection, but if the internal circuit boards malfunction, partial disassembly and repair are virtually impossible, necessitating complete replacement, resulting in wasted resources and increased costs.

[0004] Existing circuit board enclosure assembly methods have obvious drawbacks in terms of inconvenience in installation and disassembly. Whether it is welding, riveting or integral injection molding, none of them can meet the needs of quick and convenient installation, disassembly and maintenance of circuit boards. This inconvenience not only increases production and maintenance costs, but also reduces work efficiency and limits the speed of electronic equipment upgrades. Utility Model Content

[0005] To address the issue of increased production and maintenance costs caused by the difficulty in quickly and easily installing, disassembling, and maintaining circuit boards, this application provides a circuit board enclosure.

[0006] The circuit board enclosure provided in this application adopts the following technical solution:

[0018] By adopting the above technical solution, the limiting seat of the assembly is a columnar structure and is used in conjunction with internal hexagon screws, making the circuit board box easy to install and disassemble.

[0019] Optionally, the positioning seat is a column with a trapezoidal cross-section.

[0020] By adopting the above technical solution, the positioning seat is a trapezoidal column with a cross-section, which helps to position and fit more conveniently and accurately, thereby facilitating the installation and disassembly of the circuit board base and the circuit board fixing seat.

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0034] This application discloses a circuit board enclosure.

[0035] Reference Figure 1 , Figure 2 and Figure 3 As shown, the circuit board enclosure includes a circuit board mounting base 1, a circuit board housing 2, a wire seat housing 3, and a circuit board base 4. The circuit board housing 2 is mounted on the circuit board mounting base 1, the wire seat housing 3 is mounted on one side of the circuit board housing 2, and the circuit board base 4 is installed in the space formed between the circuit board mounting base 1 and the circuit board housing 2. The circuit board base 4 and the circuit board mounting base 1 are detachably connected from the outside to the inside via positioning elements 5, and the circuit board mounting base 1 and the circuit board housing 2 are detachably connected from the inside to the outside via mounting accessories 6. The entire circuit board enclosure is more convenient and quick to install and remove because the various components are not connected using traditional, difficult-to-disassemble methods, but rather detachably connected, greatly improving operational convenience. When maintenance or replacement of the circuit board is required, the various components can be easily disassembled, avoiding the difficulties and potential damage to the circuit board caused by traditional welding and riveting methods.

[0036] See Figure 4As shown, the positioning component 5 includes a positioning seat 51 and a semi-circular head screw 52. The positioning seat 51 is integrally formed on the circuit board mounting base 1. Its structural feature is a trapezoidal columnar cross-section, which increases the contact area and stability with the circuit board base 4. For example, compared to a regular rectangular columnar positioning seat 51, the trapezoidal columnar positioning seat 51 can better distribute pressure under force and is less prone to tilting or shaking. The semi-circular head screw 52 connects the circuit board base 4 and the positioning seat 51, passing through the circuit board base 4 and the positioning seat 51 in a threaded fit. The head of the semi-circular head screw 52 is semi-circular, which will not scratch surrounding components during installation and disassembly, and is more comfortable to operate. In addition to the semi-circular head screw 52, ​​a countersunk screw can also be used instead. The countersunk screw can be completely recessed into the surface of the component, making the overall surface flatter. However, in some cases where frequent disassembly is required, the operation of the semi-circular head screw 52 may be more convenient. When using the round head screw 52 to connect the circuit board base 4 and the positioning seat 51, first place the circuit board base 4 in a suitable position, then pass the round head screw 52 through the corresponding hole on the circuit board base 4, and then screw it into the threaded hole of the positioning seat 51, and tighten it to complete the connection. This connection method is simple and reliable, and when disassembly is required, simply use a corresponding screwdriver to unscrew the round head screw 52 to separate the circuit board base 4 and the circuit board mounting seat 1.

[0037] See Figure 4 As shown, the positioning seat 51 connects the circuit board base 4 and the circuit board fixing seat 1 tightly together through the threaded connection of the semi-circular head screw 52, ​​ensuring the stable installation of the circuit board base 4 in the placement space, while also allowing for easy disassembly. The threaded connection itself has good fastening properties, while the design of the semi-circular head screw 52 takes into account both the convenience of operation and the protection of surrounding components.

[0038] See Figure 4As shown, assembly 6 includes a limiting seat 61 and an internal hexagon screw 62. The limiting seat 61 is integrally formed on the inner wall of the circuit board housing 2. It is a columnar structure. The columnar structure of the limiting seat 61 is more regular, which facilitates processing and installation. For example, compared with an irregularly shaped limiting seat 61, the columnar structure is easier to position during assembly, and it can distribute the force more evenly when bearing the tensile force of the internal hexagon screw 62. The internal hexagon screw 62 passes through the circuit board fixing seat 1 and the limiting seat 61 in a threaded engagement. The advantage of the internal hexagon screw 62 is that the head has an internal hexagonal groove. When using a special internal hexagonal wrench for installation and removal, the force transmission is more direct and accurate, and it is not easy to slip. Of course, an external hexagonal bolt can also be used to replace the internal hexagon screw 62, but in some situations where space is limited, the operation of the external hexagonal bolt may not be as convenient as that of the internal hexagon screw 62. When installing the hex socket screw 62, first place the circuit board housing 2 on the circuit board mounting base 1, align the limit seat 61 with the corresponding hole on the circuit board mounting base 1, and then pass the hex socket screw 62 through the hole on one side of the circuit board mounting base 1, screw it into the threaded hole of the limit seat 61 and tighten it.

[0039] See Figure 4 As shown, the limiting seat 61 securely connects the circuit board mounting base 1 and the circuit board housing 2 together through the threaded connection of the internal hexagon screw 62, ensuring a tight fit between the circuit board housing 2 and the circuit board mounting base 1, while facilitating disassembly. The special structure of the internal hexagon screw 62 allows for the application of a large torque during tightening, making the connection more secure, while the columnar structure of the limiting seat 61 provides stable support and fit for the internal hexagon screw 62.

[0040] See Figure 2 As shown, the wire housing 3 is also equipped with a wire protection ring 7 to protect the through-hole circuit wires. The wire protection ring 7 is generally made of soft and elastic materials such as rubber or silicone, which effectively buffers the external forces on the circuit wires and prevents them from being worn or broken. For example, when the circuit wires rub against the edge of the wire housing 3 during the through-hole process, the wire protection ring 7 can act as an isolation and protection. In addition to rubber and silicone, polyurethane or other materials can also be used to make the wire protection ring 7. Polyurethane has better wear resistance and oil resistance, but the cost may be relatively higher.

[0041] See Figure 3As shown, the cross-section of the circuit board housing 2 can be rectangular, trapezoidal, or polygonal. A rectangular cross-section circuit board housing 2 has a regular structure, is easy to process and install, and is more efficient in space utilization. A trapezoidal cross-section circuit board housing 2 can be designed to be wider at the top and narrower at the bottom, or vice versa, to suit special installation environments, such as those with limited space. A polygonal cross-section circuit board housing 2 can be customized to specific functional requirements, such as when increased heat dissipation area is needed or when accommodating circuit boards of special shapes.

[0042] See Figure 2 As shown, the surfaces of the circuit board mounting base 1, the circuit board housing 2, and the wire holder housing 3 are all coated with a protective layer. This protective layer can be made of rust-preventive paint, anti-oxidation coating, etc. Rust-preventive paint prevents metal components from rusting and corroding, extending their service life. Anti-oxidation coating prevents the component surface from reacting with oxygen in the air, maintaining the component's appearance and performance. For example, for circuit board enclosures that are exposed to humid environments for extended periods, applying rust-preventive paint and anti-oxidation coating can significantly improve their durability.

[0043] The implementation principle of the circuit board box in this application embodiment is as follows: the detachable connection of each component solves the problem of inconvenient installation and disassembly of traditional circuit board boxes. The positioning component 5 and the mounting component 6 make the connection between each component both firm and easy to disassemble, saving a lot of time and effort when maintaining and replacing circuit boards. The wire protection ring 7 protects the circuit wires and improves the stability and safety of the circuit. The various cross-sectional shapes of the circuit board shell 2 and the protective layer coated on the surface of each component further enhance the applicability and durability of the circuit board box.
