Description

Technical Field

[0001] This utility model relates to the field of electrical control box design technology, specifically to an antenna introduction device. Background Technology

[0002] In fields such as industrial automation, communication equipment, and power control, electrical control boxes are widely used as protective enclosures to house electrical components, control circuits, and signal processing modules. However, electrical control boxes are typically made of metal, and while their enclosed structure effectively protects internal equipment from external physical damage or environmental interference, it can also significantly shield wireless signal transmission. When an antenna is installed inside the control box, the metal enclosure acts like a Faraday cage, severely attenuating the propagation intensity of electromagnetic waves, leading to decreased signal quality, shortened transmission distance, and reduced communication stability. Current technologies typically address this issue by directly mounting the antenna outside the control box or by simply extending the antenna feed line through perforations. However, the former often suffers from a lack of effective fixation and protection for the external antenna, making it susceptible to damage from mechanical impacts and weathering; the latter may result in poor sealing due to rough perforation structures, allowing moisture, dust, and other contaminants to penetrate the enclosure, causing short circuits, equipment corrosion, and other safety hazards. Furthermore, some improvement solutions attempt to incorporate dedicated interfaces on the enclosure, but these designs are often structurally complex, inconvenient to install and maintain, and fail to effectively balance the dual requirements of signal optimization and environmental protection. Therefore, there is an urgent need in the field for an antenna introduction device that is simple in structure, easy to install, and can simultaneously ensure signal transmission performance and enclosure sealing, in order to overcome the shortcomings of existing technologies.

[0003] Therefore, existing technologies still need further development. Utility Model Content

Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] Please see Figure 1-3 This utility model provides an antenna introduction device, comprising: It includes an inlet component and a fixing component, wherein the inlet component is configured to guide the antenna extension line from inside the electrical control box to outside the door panel, and the fixing component is configured to fix the antenna outside the door panel.

[0020] It should be further explained that the combination of the introduction component and the fixing component enables the antenna to be led from inside the electrical control box to the outside. In specific implementation, the device is installed on the door panel of the electrical control box. The introduction component typically consists of a guide structure, such as a component with through holes, used to accommodate the antenna extension cable and safely guide it from inside the box to the outside of the door panel. The fixing component is designed as a clamping or locking mechanism to securely fix the antenna to the outside of the door panel, preventing it from falling off due to vibration or external force. During installation, the introduction component is first integrated into the predetermined position on the door panel, then the antenna extension cable is inserted, and finally the antenna 2 is connected and fixed by the fixing component. The beneficial effect of this design is that it effectively solves the signal attenuation problem caused by the metal shielding of the electrical control box. By moving the antenna to the outside, the signal strength, transmission distance, and stability are significantly improved, while the maintenance process is simplified because the antenna can be easily removed without affecting the internal circuitry of the box. Those skilled in the art can select appropriate materials, such as plastic or metal, to manufacture the components based on the conventional electrical control box structure, ensuring compatibility and durability.

[0021] Specifically, the introduction component includes an antenna extension line introduction device 3.

[0022] It should be further explained that the introduced components include the antenna extension cable introduction device 3. In specific implementations, this device can be designed as a separate mounting base or sleeve, preferably made of insulating materials such as engineering plastics to reduce electromagnetic interference. The antenna extension cable introduction device 3 is fixed to the door panel by screws or clips, and its interior has guide grooves or holes to guide the antenna extension cable smoothly through the door panel, avoiding cable wear. The beneficial effects are enhanced guidance accuracy and reliability, reduced risk of bending or twisting of the antenna extension cable during the threading process, thus ensuring the continuity of signal transmission. Simultaneously, this device can be mass-produced as a standardized component, reducing manufacturing costs and installation complexity.

[0023] Specifically, the antenna extension line introduction device 3 includes a mounting part disposed on the door panel, the mounting part having a channel penetrating the door panel.

[0024] It should be further explained that the structure of the antenna extension cable introduction device 3 includes a mounting part on the door panel and a channel penetrating the door panel. In implementation, the mounting part can be a flange or base, connected to the door panel by welding or bolts to ensure stability; the channel is a round or square hole with a diameter slightly larger than the antenna extension cable, and a smooth inner wall to reduce friction. During installation, holes must first be drilled in the door panel, then the mounting part is fixed, and the channel is aligned with the hole to allow the antenna extension cable to pass smoothly. The beneficial effects of this design are that it provides mechanical support and guidance, prevents the cable from being squeezed when the door panel is opened and closed, extends the service life of the antenna system, and the through-channel design ensures the shortest path for the signal cable, minimizing signal loss.

[0025] Specifically, the antenna extension cable introduction device 3 also includes an antenna extension cable fixing head 4, which is configured to connect the antenna extension cable 5.

[0026] It should be further explained that an antenna extension cable fixing head 4 is added to the antenna extension cable introduction device 3. This fixing head can be designed as a connector or joint in implementation for reliably connecting the antenna extension cable 5, as shown in the attached diagram. Figure 1 As shown, the antenna extension cable 5 is guided out of the control box through the fixing head. Specifically, the antenna extension cable fixing head 4 can adopt a threaded or plug-in structure, installed at the outlet end of the antenna extension cable inlet device 3, and fixes the antenna extension cable 5 by tightening or snapping to prevent it from loosening. The beneficial effects are that it enables quick connection and disassembly, facilitates on-site debugging or antenna replacement, and at the same time, the fixing head provides additional sealing and strain relief functions, reducing connection failures caused by cable swing and improving the overall system reliability.

[0027] Specifically, the fixing component includes an external fixing block 1.

[0028] It should be further explained that the fixing component includes an external fixing block 1. In specific implementations, the external fixing block 1 can be a block-shaped component made of plastic or metal, fixed to the outside of the door panel by adhesive or screws. Its surface has grooves or clamping mechanisms for accommodating and fixing the antenna 2. During installation, the external fixing block 1 is first aligned with the door panel and fixed. The end of the antenna extension cable 5 or the antenna 2 is inserted into or locked onto the fixing block. Then, the end of the antenna extension cable 5 or the antenna 2 connected to it is fixed to the fixing block. For example, the antenna 2 or the end of the antenna extension cable 5 can be quickly installed and removed using a press-type buckle. This design ensures that the antenna 2 is ultimately securely fixed to the outside of the enclosure. The beneficial effects are that it provides a sturdy support point, preventing the antenna from shifting due to wind or human touch, ensuring the stability of the antenna direction, thereby optimizing the signal reception quality. Furthermore, the design of the fixing block allows the antenna angle to be adjusted to adapt to different environmental requirements.

[0029] Specifically, the external fixing block 1 has a fixing structure for detachably fixing the antenna 2.

[0030] It should be further explained that the external fixing block 1 has a fixing structure for detachably fixing the antenna 2. In implementation, this fixing structure can be a flexible snap-fit, a slider, or a quick-release mechanism. For example, a press-type snap-fit ​​allows for quick installation and removal of the antenna. A corresponding protrusion can be designed on the bottom of the antenna 2 to engage with the fixing structure. The beneficial effects are greatly improved maintenance convenience; operators can replace the antenna without tools, reducing downtime. Simultaneously, the detachable design of the fixing structure allows for the use of different types of antennas, enhancing the versatility and adaptability of the device.

[0031] Specifically, the fixing structure includes a snap-fit ​​or a screw hole.

[0032] It should be further explained that the fixing structure includes either clips or screw holes. In implementation, the clip structure can use plastic spring sheets to lock the antenna in place through elastic deformation; the screw holes allow the antenna to be directly tightened onto the external fixing block 1 using screws. For example, in high-vibration environments, screw hole fixing is preferred to provide stronger clamping force. The advantage is that it provides multiple fixing options to adapt to different application scenarios: clip-on types are suitable for frequent replacements, while screw hole types are suitable for permanent installations, ensuring the flexibility and reliability of the fixing method, thereby enhancing the product's market competitiveness.

[0033] Specifically, the inlet component includes a sealing element to prevent moisture or dust from entering the electrical control box.

[0034] It should be further explained that the entry component includes a sealing element to prevent moisture or dust from entering the electrical control box. In practice, this sealing element can be integrated around the channel of the antenna extension cable entry device 3, for example, using rubber gaskets or sealant to fill the gaps after wiring. During installation, it is essential to ensure that the sealing element is tightly fitted to the door panel and cables, forming a sealed barrier. The beneficial effect is a significant improvement in the protection level of the electrical control box, preventing external environmental contaminants from causing short circuits or corrosion. It is particularly suitable for outdoor or industrial environments, extending equipment lifespan and meeting IP protection standards.

[0035] Specifically, the sealing component includes a sealing ring disposed within the inlet channel.

[0036] It should be further explained that the sealing component includes a sealing ring disposed within the inlet channel. In implementation, this sealing ring can be an O-ring or a custom-made annular gasket, embedded in the inner wall of the channel of the antenna extension cable inlet device 3. When the antenna extension cable 5 passes through, the sealing ring is compressed and deformed, achieving a dynamic seal. The beneficial effects are that it provides highly efficient sealing performance, maintaining a tight seal even with frequent opening and closing of the door panel, preventing moisture and dust penetration. Simultaneously, the replaceable design of the sealing ring facilitates maintenance and reduces long-term operating costs.

[0037] Specifically, the sealing ring is made of rubber or silicone material.

[0038] It should be further noted that the sealing ring is made of rubber or silicone. In practice, rubber materials such as nitrile rubber are suitable for general environments, providing good elasticity and wear resistance; silicone is more suitable for high-temperature or chemically corrosive environments, exhibiting excellent weather resistance. During installation, simply press the sealing ring into the predetermined groove. The beneficial effects are ensuring the durability and adaptability of the sealing components, a wide range of material choices that can be optimized according to actual needs, thereby improving the reliability of the device under various operating conditions and reducing the risk of failure due to seal failure.

[0039] The technical features described above can be combined arbitrarily. Although not all possible combinations of these technical features are described, any combination of these technical features should be considered to be covered by this specification, provided that such combination does not contain contradictions.
