Detailed Implementation

[0023] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] Example 1, see Figure 1-4 The purpose of this embodiment is to address the problem of low space utilization in mosaic tile displays by providing a mosaic functional component, including an operation trigger module 1, a functional module 2, and a metal shielding housing 3. The functional module 2 is fixed inside the metal shielding housing 3. The operation trigger module 1 is fixed to the top of the metal shielding housing 3 and electrically connected to the functional module 2. The bottom side of the metal shielding housing 3 has a right-angled single-step recessed structure 31. An integrated cable shielding plug 32 is fixedly installed on the vertical side of the right-angled single-step recessed structure 31 and is electrically connected to the functional module 2. The integrated cable shielding plug 32 is a DB cable shielded female connector, but an aviation shielded female connector can also be used as needed.

[0025] With the same maximum length, width, and height, the mosaic functional component with a right-angled single-step recessed structure 31 at the bottom has a higher space utilization rate than the full-size mosaic functional component. It greatly reduces the depth space occupied by the male and female plugs of the integrated cable, and facilitates the installation and maintenance of other necessary modular components in the compact space of the mosaic panel.

[0026] The use of integrated shielded cable male and female connectors enables rapid installation and disassembly, improving installation efficiency and reducing the risk of damage caused by frequent disassembly and reassembly of non-integrated loose cables. It offers high flexibility, quickly adapting to different mosaic modules to fulfill diverse functional requirements, allowing the control panel to respond more quickly to complex and changing usage scenarios.

[0027] Furthermore, a ring plate 34 is fixed around the top side of the metal shielding shell 3 by screws 33. The ring plate 34 has several downwardly extending protrusions 35 on both sides away from the double-link single-fold spring sheet 4 along the metal shielding shell 3. Arc-shaped guide grooves 36 are opened on the four sides of the metal shielding shell 3.

[0028] Several protrusions 35 and the intervals between them form corresponding recessed areas that correspond to the recessed areas and protrusions set on the mosaic plate support frame, and the two are interlocked and fixed together; the arc-shaped guide groove 36 cooperates with the arc-shaped guide protrusions set on the mosaic plate support frame, and plays a guiding and fixing role when interlocked and fixed.

[0029] Furthermore, the side of the metal shielding shell 3 is fixed with screws to one end of a double-linked single-folding spring clip 4, and the other end is composed of two independent single-folding spring clips, which are movably snapped between the other opposite sides of the surrounding plate 34 and the metal shielding shell 3. Multiple double-linked single-folding spring clips 4 can be provided, with two independent spring clips on one end moving independently, and the other end connected in parallel. This reduces the number of parts to be assembled while increasing the number of independent snapping points, making the fixation of the mosaic functional components more secure.

[0030] The double-linked single-fold spring clip 4 is used to interlock and fix the grid-type mosaic tile frame on the mosaic tile platform. The relative position of the interlocking and fixing can be referred to the relative position relationship between the long hook and the metal grid when they are engaged in Figure 8 of another application of the applicant CN202122163602.7.

[0031] Furthermore, the metal shielding shell 3 is provided with a mounting top plate 5 on its top, and a receiving hole 51 is provided in the middle of the mounting top plate 5, and the operation trigger module 1 is located in the receiving hole 51; the surrounding retaining plate 34 is provided with a retaining slot 37 on its opposite sides, and a retaining foot 52 is fixedly provided below the mounting top plate 5 to engage and fix with the retaining slot 37.

[0032] While reducing the depth of the mosaic functional components towards the mosaic panel, the space is expanded to the outside. The installation of the top plate can reduce the height difference of the operation trigger module protruding from the mosaic panel, and can also protect the operation trigger module from all sides. The structure of the latch and foot further improves the efficiency of quick assembly and disassembly.

[0033] Furthermore, an anti-accidental contact device 6 is provided above the mounting top plate 5. The anti-accidental contact device 6 includes a fixing block 61, a support column 62, a protective cover 63, and a rotating shaft 64. The fixing block 61 is fixedly mounted on the mounting top plate 5, and the protective cover 63 is hinged to the fixing block 61 via the rotating shaft 64. A support column 62 corresponding to the protective cover 63 is fixedly mounted on the other side of the receiving hole 51 relative to the fixing block 61. A label position 7 is provided above the mounting top plate 5. A torsion spring 65 is sleeved on the rotating shaft 64, with one end of the torsion spring 65 engaged with the protective cover 63 and the other end engaged with the fixing block 61.

[0034] In nuclear power plants and other critical mosaic panel operation scenarios, operational accuracy is paramount, and misoperation must be prevented. The anti-accidental touch device 6 provides shielding protection for the operation trigger module 1; the torsion spring 65 adds a self-resetting function to the anti-accidental touch device 6; and the integrated design of the label position 7 with the mosaic components further improves debugging and installation efficiency and reduces the probability of misoperation.

[0035] Working principle: The right-angled single-step recessed structure 31 of this mosaic functional component is connected to the internal equipment cable of the mosaic panel via an integrated cable shielded male and female plug. It is guided and fixed by the protrusion 35 on the surrounding plate and the arc-shaped guide groove 36, which are inserted into the recessed area and arc-shaped guide protrusion of the mosaic panel support frame. In use, the operator first confirms that the label on the label position 7 of this mosaic functional component indicates the module to be operated. Then, the operator flips open the protective cover 63 with one hand and operates the operation trigger module 1 with the other hand. After the operation is completed, the operator stops applying pressure to the protective cover 63. The protective cover will then flip and abut against the support column 62 under the action of the torsion spring 65, without further touching the operation trigger module.

[0036] Compared with existing technologies, this invention reduces the size of the mosaic functional components and, based on the internal space of the mosaic panel, minimizes the depth space occupied by the components, offering advantages in integration and ease of operation. The integrated shielded cable connector enables quick plugging and unplugging while meeting the equipment's isolation requirements. The self-resetting anti-accidental touch device allows operators to confirm before operation to prevent accidental activation, while visual and manual operation enhances attention and judgment, thereby improving operational accuracy. It avoids errors caused by human negligence or fatigue.

[0037] Example 2, see Figure 5 and 6 The technical effect achieved in this embodiment is the same as that in embodiment 1, the only difference being that the integrated cable shielding plug 32 is fixed at a different position on the right-angled single-step recessed structure 31.

[0038] A mosaic functional component includes an operation trigger module 1, a functional module 2, and a metal shielding shell 3. The functional module 2 is fixed inside the metal shielding shell 3. The operation trigger module 1 is fixed to the top of the metal shielding shell 3 and electrically connected to the functional module 2. The bottom side of the metal shielding shell has a right-angled single-step recessed structure 31. An integrated cable shielding plug 32 is fixedly provided on the top surface of the right-angled single-step recessed structure 31 and is electrically connected to the functional module 2.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
