Description

Technical Field

[0001] This utility model relates to the field of shielding housing technology, and in particular to an anti-interference shielding housing structure for a pluggable PLC remote I / O module. Background Technology

[0002] Anti-interference shielding housing is a metal protective structure designed specifically for electronic devices. It is mainly used in industrial control equipment such as pluggable PLC remote I / O modules. Its core function is to effectively block external electromagnetic interference and radio frequency interference by forming a Faraday cage effect through conductive metal materials, thus ensuring the stability of signal transmission. Typical application scenarios include strong electromagnetic environments such as industrial production lines with dense frequency converters and near high-voltage substations, as well as mobile devices with complex electromagnetic compatibility requirements such as rail transportation and ships.

[0003] However, it still has some drawbacks. For example, the traditional housing is fixed with bolts, which makes disassembly and assembly cumbersome and time-consuming. Vibration buffering relies only on a single layer of pads and fails to achieve a double-layer shock absorption effect. In view of this, this utility model proposes a pluggable PLC remote I / O module anti-interference shielding housing structure. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a pluggable PLC remote I / O module anti-interference shielding shell structure.

[0005] The technical solution of this utility model is: a pluggable PLC remote I / O module anti-interference shielding shell structure, including an upper anti-interference shell, and the outer surfaces on both sides of the upper anti-interference shell are provided with buckle holes, and the inner wall of the buckle holes is movably connected with a spring buckle device.

[0006] The inner wall of the upper anti-interference shell is movably sleeved with the lower anti-interference shell, and the upper and lower anti-interference shells are connected by a spring-loaded buckle device and a buckle hole.

[0007] Optionally, the inner cavity of the upper anti-interference shell and the inner wall of the lower anti-interference shell are both fixedly connected with buffer pads.

[0008] Optionally, the spring-loaded latching device is disposed on both outer surfaces of the lower anti-interference housing.

[0009] Optionally, the spring-loaded latching device consists of an anti-accidental-touch cover and a spring button, with the anti-accidental-touch cover covering the outside of the spring button.

[0010] Optionally, a spring base is fixedly connected to the outer surface of the end of the spring button away from the anti-accidental touch cover, and a damping spring is provided between the spring base and the lower anti-interference shell.

[0011] Optionally, one end of the damping spring is fixedly connected to the spring base, and the other end of the damping spring is movably connected to the lower anti-interference shell.

[0012] Optionally, both the upper and lower anti-interference shells are made of conductive metal.

[0013] Optionally, the buffer pad is made of elastic rubber, and the surface of the buffer pad is provided with anti-slip texture. The upper anti-interference shell and the lower anti-interference shell close the two sets of buffer pads to form a double-layer buffer structure.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This utility model, through the design of an upper anti-interference shell and a lower anti-interference shell, facilitates the quick installation and disassembly of the module. The linkage design of the buckle hole and the spring buckle device ensures the connection stability. The overall structure has multiple advantages such as anti-interference, shock resistance, prevention of accidental contact, and convenient maintenance, which significantly improves the reliability and service life of the PLC remote I / O module in the industrial environment.

[0016] Furthermore, the addition of a buffer pad allows for effective absorption of vibration and impact through a double-layer design within the upper and lower anti-interference shells. The combination of the anti-accidental touch cover and the spring button prevents accidental operation, while the cooperation between the spring base and the damping spring provides stable buffering and rebound force.

[0017] Furthermore, by using conductive metal materials for both the upper and lower anti-interference shells, a sealed cavity is formed when closed, which can effectively shield electromagnetic interference signals in the industrial environment; it is compatible with remote I / O modules of different sizes, and can meet the protection requirements of multiple module models without replacing the shell, reducing the equipment replacement cost and inventory pressure for enterprises;

[0018] In summary, this utility model achieves quick insertion and stable connection of modules through a spring-loaded latching device, supplemented by double-layered cushioning pads to absorb vibration and an anti-accidental touch cover to avoid misoperation. It effectively shields electromagnetic interference, is compatible with modules of multiple sizes, reduces enterprise costs, and significantly improves the reliability and service life of PLC remote I / O modules in industrial environments.

[0030] Example

[0031] like Figures 1 to 4As shown, the present invention proposes a pluggable PLC remote I / O module anti-interference shielding housing structure, including an upper anti-interference housing 1, which is a rectangular box with an opening at the bottom and is galvanized for rust prevention. The upper anti-interference housing 1 has buckle holes 4 on both outer surfaces. The inner wall of the buckle holes 4 is movably connected to a spring buckle device 5. The spring buckle devices 5 are set on both outer surfaces of the lower anti-interference housing 2, with one set on each side and symmetrically distributed.

[0032] like Figure 2 and Figure 3 As shown, the lower anti-interference shell 2 is movably sleeved on the inner wall of the upper anti-interference shell 1. The lower anti-interference shell 2 is a rectangular box with an open top, and its height is lower than that of the upper anti-interference shell 1. Its outer diameter is smaller than that of the upper anti-interference shell 1, ensuring smooth sleeve connection. Both the upper anti-interference shell 1 and the lower anti-interference shell 2 are made of conductive metal. The inner cavity of the upper anti-interference shell 1 and the inner wall of the lower anti-interference shell 2 are fixedly connected with buffer pads 3. The buffer pads 3 are made of elastic rubber, and the surface of the buffer pads 3 is provided with anti-slip texture. The upper anti-interference shell 1 and the lower anti-interference shell 2 close the two sets of buffer pads 3 to form a double-layer buffer structure.

[0033] like Figure 1 and Figure 2 As shown, the upper anti-interference shell 1 and the lower anti-interference shell 2 are connected by a spring-loaded latching device 5 and a latching hole 4 for plug-in / plug-out connection; refer to Figure 4 As shown, the spring latch device 5 consists of an anti-accidental touch cover 6 and a spring button 7. The anti-accidental touch cover 6 covers the outside of the spring button 7. A spring base 9 is fixedly connected to the outer surface of the end of the spring button 7 away from the anti-accidental touch cover 6. A damping spring 8 is provided between the spring base 9 and the lower anti-interference shell 2. One end of the damping spring 8 is fixedly connected to the spring base 9, and the other end of the damping spring 8 is movably connected to the lower anti-interference shell 2.

[0034] In this embodiment, during installation, the PLC remote I / O module is placed inside the lower anti-interference shell 2, and the buffer pad 3 on its inner wall first forms a preliminary wrapping and positioning of the module; then the upper anti-interference shell 1 is vertically inserted into the opening of the lower anti-interference shell 2. At this time, the inner wall of the upper anti-interference shell 1 presses the spring buttons 7 on both sides of the lower anti-interference shell 2. The spring buttons 7 drive the spring base 9 to compress the damping spring 8, so that the spring buttons 7 retract into the side wall of the lower anti-interference shell 2, ensuring that the upper anti-interference shell 1 is smoothly inserted.

[0035] When the sleeve is in place, the spring button 7 is precisely aligned with the snap hole 4 of the upper anti-interference shell 1, and the damping spring 8 releases its elastic potential energy to push the spring button 7 out and embed it into the snap hole 4, thus completing the quick connection of the anti-interference shell.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
