Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a relay dustproof device. Background Technology

[0002] To ensure the long-term stable operation of relays, dustproof design is particularly important. Currently, dustproof relays on the market mainly rely on dust covers. This design aims to prevent dust from entering the relay and avoid dust from contaminating and damaging key components such as contacts and coils, thereby extending the service life and reliability of the relay. The dust cover is usually connected to the relay body in a hinged manner, which is convenient to open and close while maintaining the compactness of the structure.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] Currently, most relay terminals are still secured using screw connections. While this provides a secure mechanical connection, it presents several inconveniences in practice. First, screw fixing makes the wiring process cumbersome and time-consuming, increasing the difficulty of installation and maintenance. Second, when the relay needs repair or replacement, the screw installation and removal process is equally complex, not only time-consuming and labor-intensive but also potentially leading to loosening or damage to the wiring due to improper operation. More importantly, the presence of the dust cover often interferes with screw installation and removal. Due to the limited space between the dust cover and the relay body, tightening and loosening the screws becomes particularly difficult, and improper operation may even damage the dust cover or the relay body.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model proposes a relay dustproof device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A dustproof device for a relay includes a relay body and two wiring structures respectively located at the front and rear of the relay body.

[0009] The wiring structure includes two copper plates respectively embedded at the corners of the relay body, a cover plate hinged to the relay body and movably covering the two copper plates, and two clamping blocks located inside the cover plate, each corresponding to one of the two copper plates. Each clamping block has a rubber clip on the side away from the hinged end of the cover plate for wire clamping. Two U-shaped grooves are formed on one side wall of the cover plate, each corresponding to one of the rubber clips, allowing wires to pass through.

[0010] It also includes positioning components for securing the cover plate.

[0011] Preferably, the front and rear side walls of the relay body are provided with rubber hinge seats for mounting a cover plate.

[0012] Preferably, it also includes a mounting base located on the inside of the cover plate for positioning and fixing the clamping block and rubber clip.

[0013] Preferably, the clamping block consists of a ceramic base and a pressure plate clamped to its bottom.

[0014] Preferably, the top surface of the copper sheet is provided with a contact with an upwardly convex structure, the bottom surface of the pressure plate is provided with a groove in the middle for accommodating the contact, and the outer side of the groove is provided with a through groove for wiring to pass through.

[0015] Preferably, the positioning component includes a screw rod disposed between two U-shaped grooves and threaded through the side wall of the cover plate, and a fixing plate mounted between two copper sheets, wherein the fixing plate has a limiting hole through which the screw rod can pass.

[0016] The beneficial effects of this utility model are:

[0017] The technical solution of this utility model is to set a clamping block and a rubber clip on the inner side of the cover plate. The terminal can pass through the U-shaped groove and be quickly clamped and fixed on the clamping block with the help of the rubber clip. At the same time, as the cover plate is fastened, the terminal can be clamped and fixed with the clamping block and the copper sheet. Compared with the traditional screw fixing method, it is not only convenient to disassemble and assemble, but also effectively utilizes the dust cover structure and reduces the difficulty of installation and maintenance.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Please see Figure 1-5 This utility model provides a technical solution: a relay dustproof device, including a relay body 100 and two wiring structures 200 respectively located at the front and rear of the relay body 100. The wiring structure 200 includes two copper pieces 210 respectively embedded at the corners of the two sides of the relay body 100 and a cover plate 220 hinged to the relay body 100 and movably covering the two copper pieces 210. It also includes two clamping blocks 230 located inside the cover plate 220 and corresponding to the two copper pieces 210 respectively. Each clamping block 230 has a rubber clip 240 on the side away from the hinge end of the cover plate 220 for wiring to be clamped. Two U-shaped grooves 250 are opened on one side wall of the cover plate 220, corresponding to the two rubber clips 240 respectively, for wiring to pass through. It also includes a positioning component 300 for fixing the cover plate 220.

[0036] Based on the above structural design, this relay dustproof device consists of a relay body 100 and two wiring structures 200. It is mainly used to achieve quick and stable connection of the wiring terminals and convenient operation of the dustproof cover. Specifically, during the wiring process, firstly, the wire to be connected is inserted through the U-shaped groove 250 on the side wall of the cover plate 220, ensuring its wiring terminal contacts the clamping block 230. Subsequently, the wire is clamped and fixed using rubber clips 240. The rubber clips 240 provide sufficient clamping force to ensure a stable connection of the wire. Due to their material properties, they also possess good elasticity and wear resistance, which can, to a certain extent, prevent the wire from loosening or being damaged by external forces. The cover plate 220 is connected to the relay body 100 via a hinge, allowing it to open and close freely for easy wire insertion and dustproof cover closure. When the cover plate 220 is closed, the terminal fixed to the clamping block 230 by the rubber clip 240 eventually contacts the copper sheet 210 as the cover plate 220 moves, and is fixed under the clamping action of the clamping block 230 and the copper sheet 210. At the same time, the cover plate 220 covers the outside, forming an effective dustproof barrier. This relay dustproof device, by setting the clamping block 230 and the rubber clip 240 on the inside of the cover plate 220, allows the terminal to pass through the U-shaped groove 250 and achieve quick snap-fit ​​and fixation on the clamping block 230 with the help of the rubber clip 240. At the same time, as the cover plate 220 is closed, the clamping block 230 and the copper sheet 210 can clamp and fix the terminal. Compared with the traditional screw fixing method, it is not only convenient to disassemble and assemble, but also effectively utilizes the dustproof cover structure, reducing the difficulty of installation and maintenance.

[0037] Furthermore, rubber hinge seats 110 are provided on the front and rear side walls of the relay body 100 for mounting the cover plate 220. The rubber hinge seats 110 serve as the connecting component between the cover plate 220 and the relay body 100, providing a stable hinge point. This design allows the cover plate 220 to open and close smoothly on the relay body 100, ensuring structural compactness while facilitating wire access and dust cover closure. The material and structural design of the rubber hinge seats 110 enable them to withstand certain torque and bending moments, ensuring that the hinge point will not be damaged due to excessive force during the opening and closing of the cover plate 220. In addition, the design of the rubber hinge seats 110 also considers ease of maintenance and repair. When it is necessary to disassemble or replace the cover plate 220, it can be done simply by gently rotating or moving the cover plate 220. This design not only simplifies the operation steps but also reduces maintenance costs.

[0038] Furthermore, it also includes a mounting base 2210 located inside the cover plate 220 for positioning and securing the clamping blocks 230 and rubber clips 240. Two mounting bases 2210 are provided inside one cover plate 220, respectively for positioning and installing the two clamping blocks 230 and the two rubber clips 240. The mounting base 2210 is integrally formed with the cover plate 220, providing structural support for the combined installation and layout of the clamping blocks 230 and rubber clips 240, ensuring that both are firmly installed in their fixed positions inside the cover plate 220, so as to smoothly achieve the function of fixing the wires.

[0039] Furthermore, the clamping block 230 consists of a ceramic base 2310 and a pressure plate 2320 clamped to its bottom. The ceramic base 2310 is made of a ceramic material with high insulation properties, possessing extremely high resistivity and dielectric strength. It is located between the pressure plate 2320 and the cover plate 220, effectively isolating the direct contact between the two and preventing current from flowing through unintended paths, thereby ensuring the electrical safety inside the device.

[0040] Furthermore, the top surface of the copper sheet 210 is provided with a contact 2110 with an upwardly convex structure, and the bottom surface of the pressure plate 2320 has a groove 2321 in the middle for accommodating the contact 2110, and a through groove 2322 for wiring to pass through is provided on the outer side of the groove 2321. The upwardly convex contact 2110 on the top surface of the copper sheet 210 can be precisely positioned within the groove 2321 on the bottom surface of the pressure plate 2320. This design ensures that the contact 2110 maintains a stable position in the closed state and limits the wiring terminal, avoiding poor contact caused by the wiring terminal's positional misalignment.

[0041] Furthermore, the positioning component 300 includes a screw 310 disposed between two U-shaped grooves 250 and threaded through the side wall of the cover plate 220, and a fixing plate 320 mounted between two copper sheets 210. The fixing plate 320 has a limiting hole 330 through which the screw 310 can pass. The positioning component 300 effectively fixes the cover plate 220 in the closed state, further enhancing the dustproof effect. The screw 310 threaded onto the cover plate 220 not only serves as a limiting support structure but also facilitates the operation of the cover plate 220 by the operator.

[0042] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
