Description

Technical Field

[0001] This utility model relates to a rainproof structure for outdoor circuit boards, belonging to the technical field of outdoor facilities. Background Technology

[0002] With the continuous development of technology, outdoor lighting projects are ubiquitous, with neon lights, colored lights, LED light strips, and other forms of lighting equipment adorning the city's nightscape. Each lighting facility requires circuit boards and wires / cables to connect and control the lighting. However, existing outdoor circuit boards lack rain protection. Once the circuit boards are corroded by rainwater, it will cause circuit breaks and damage, requiring repeated repairs or replacements, resulting in significant maintenance costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an outdoor circuit board rainproof structure. This outdoor circuit board rainproof structure can not only effectively wrap the circuit board, but also effectively prevent rainwater from entering the front and rear mating surfaces, thereby protecting the safety of the internal circuit board.

[0004] To solve the above problems, the specific technical solution of this utility model is as follows: an outdoor circuit board rainproof structure, comprising a circuit box formed by fastening a front end plate and a rear end plate, with the circuit board located inside the cavity of the circuit box; a sealing strip is provided on the upper surface or outer periphery of the fastening surface of the front end plate and the rear end plate; at least one cable outlet is provided at the fastening point of the front end plate and the rear end plate, and the cable connected to the circuit board passes through the cable outlet, bends, and then adheres to the rear end plate; the sealing strip covers and presses firmly on the cable outlet and the bent cable to form a seal; a clamp is provided on the outside of the sealing strip, and the clamp presses the sealing strip firmly on the fastening surface of the front end plate and the rear end plate.

[0005] The cable outlet is located on the front-end board and / or the rear-end board.

[0006] The rear panel has a wire groove that connects to the outlet, and the cable extending out of the outlet is arranged in close contact with the wire groove.

[0007] A limiting platform is provided on the front end plate, and the front end of the sealing strip contacts and seals with the limiting platform; the rear end of the sealing strip extends out of the end face of the rear end plate.

[0008] The circuit box is circular or polygonal.

[0009] The circuit box is circular, and the sealing strip is annular.

[0010] The rear surface of the rear end plate is provided with a vent hole at the upper end.

[0011] The outdoor circuit board rainproof structure of this application adopts the above-described structure and has the following advantages: 1. Sealing strips are used to seal the mating surfaces of the front and rear end plates, effectively preventing rain damage; 2; When a cable extends out, the cable is bent against the rear end plate, and then a sealing strip is installed to effectively fill the gap between the cable and the outlet, ensuring rainproof performance; 3. A wire groove is provided at the outlet, which allows the cable to be placed in the wire groove, so that the coil bends and fits against the rear end plate, blocking the outlet and thus providing rain protection. 4. One side of the sealing strip contacts the limiting platform for sealing, while the other side extends out of the end face of the rear panel to further protect against rain.

[0017] Figure 6 for Figure 5 BB sectional view (installation of sealing strips and clamps). Detailed Implementation Example 1

[0018] like Figure 1 As shown, an outdoor circuit board rainproof structure comprises a rectangular circuit box formed by the snap-fitting of a front end plate 1 and a rear end plate 2, with the circuit board 3 located within the cavity of the circuit box. A sealing strip 4 is provided on the upper surface or outer periphery of the snap-fitting surfaces of the front end plate 1 and the rear end plate 2. The sealing strip 4 can be conventionally selected by those skilled in the art through snap-fitting, pressure plate fixing, or as a single annular ring for integral fitting, as long as the sealing strip 4 adheres tightly to the outer surface of the snap-fitting surfaces of the front end plate 1 and the rear end plate 2. Example 2

[0019] like Figure 2As shown, an outdoor circuit board rainproof structure, based on the structure of Embodiment 1, has at least one cable outlet 5 at the fastening point of the front end plate 1 and the rear end plate 2 to ensure the connection control between the circuit board and external devices. The cable outlet 5 can be machined on the fastening surface of the front end plate 1 or the fastening surface of the rear end plate 2. The cable connected to the circuit board 3 passes through the cable outlet 5, bends, and then adheres to the rear end plate 2. A sealing strip 4 covers and presses firmly on the cable outlet and the bent cable. Since the sealing strip 4 is elastic, during the pressing process, the sealing strip 4 completely adheres to the cable and the outer periphery of the circuit box to form a seal, thereby achieving the rainproof function. Example 3

[0020] like Figure 3 and Figure 4 As shown, an outdoor circuit board rainproof structure, based on the structure of Embodiment 2, has a wire groove 6 on the rear end plate 2 that communicates with the cable outlet 5. The cable extending out of the cable outlet 5 is arranged in close contact with the wire groove 6. The cable is placed inside the wire groove 6, and a thin, rotatable sealing strip 4 covers the wire groove 6, thereby achieving the rainproof function.

[0021] A limiting platform 8 is provided on the front panel 1. One end of the sealing strip 4 contacts and seals with the limiting platform 8, and the rear side of the sealing strip 4 extends out of the end face of the rear panel 2. In this way, one end of the sealing strip 4 seals with the front panel 1, and the rear end extends out of the end face of the rear panel 2 to provide rain protection, thereby achieving the overall rainproof performance of the circuit box. Example 4

[0022] like Figure 5 and Figure 6 As shown, an outdoor circuit board rainproof structure comprises a circular circuit box formed by the snap-fitting of a front panel 1 and a rear panel 2, with the circuit board 3 located inside the cavity of the circuit box. The rear panel 2 has several evenly distributed cable outlets 5 on its snap-fit ​​surface, and a wire groove 6 communicating with the cable outlets 5. Cables connected to the circuit board 3 pass through the cable outlets 5, bend at a 90° angle towards the rear panel 2, and are arranged along the wire groove 6 before connecting to external equipment. An annular sealing strip 4 covers and presses firmly onto the cable outlets and the wire groove 6. A limiting platform 8 is provided on the front panel 1, and one end of the sealing strip 4 contacts and seals against the limiting platform 8. The rear side of the sealing strip 4 extends beyond the end face of the rear panel 2. Thus, the front end of the sealing strip 4 seals against the front panel 1, and the rear end extends beyond the end face of the rear panel 2 to provide rain protection, thereby achieving the overall rainproof performance of the circuit box. To ensure that the position of the sealing strip 4 does not shift, the sealing strip 4 is pressed firmly against the outer surface of the annular sealing strip 4 by an annular clamp 7.

[0023] In the above embodiments one to four, a vent hole 9 is provided on the upper end of the rear surface of the rear end plate 2 to facilitate the dissipation of heat generated by the circuit board 3 and avoid the generation of negative pressure inside to absorb water vapor.
