[0029] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0030] like Figure 1-7 As shown, a multifunctional DC electronic switch includes a housing 1 and a switch body 2. The switch body 2 has an operation panel 21 on one side and a wiring port 22 on the other. The housing 1 has an insertion port 11 on one side and a wire passage port 12 on the other. One side of the switch body 2 is flush with the insertion port 11, and the wiring port 22 is inserted into the wire passage port 12. This allows the switch body 2 to be stably installed within the housing 1, facilitating operation and wiring. The switch body 2 is the core component for controlling the DC current flow. Its operation panel 21 is used for operator control. The wiring port 22 is used to connect to external circuits; its shape and structure need to be designed according to specific wiring requirements, and generally, pluggable external wires can be used. The housing 1 protects the switch body 2. The size and shape of the insertion port 11 are adapted to the switch body 2 to ensure smooth insertion. The wire passage port 12 must accommodate the wiring port 22.
[0031] The housing 1 has a heat dissipation vent 13 at both the top and bottom. A pair of retaining strips 3 are arranged parallel to each other on both sides of the heat dissipation vent 13, and a perforated plate 4 for heat dissipation is inserted between the retaining strips 3, covering the heat dissipation vent 13. The size of the heat dissipation vent 13 is close to the top area of the housing 1, which effectively improves the heat dissipation efficiency of the switch body 2 and avoids affecting the performance and stability of the switch due to heat accumulation. A pull plate 5 is provided on one side of the perforated plate 4, extending along the thickness direction of the housing 1. There is a distance between the pull plate 5 and the side of the housing 1 with the wire through hole 12. The pull plate 5 facilitates the installation and removal of the perforated plate 4, making it easy to replace the perforated plate 4, thereby ensuring that the housing 1 can reliably dissipate heat from the switch body 2.
[0032] A pair of retaining strips 3 are provided at the top and bottom of the housing 1. The extension direction of the retaining strips 3 is consistent with the direction in which the switch body 2 is inserted into the housing 1. The retaining strips 3 are L-shaped, and the horizontal end of the retaining strips 3 forms an insertion groove 31 between itself and the housing 1. The perforated plate 4 is inserted into the insertion groove 31 to fit comfortably. In this way, the installation of the perforated plate 4 is more stable, and it can better cover the heat dissipation vent 13 to ensure heat dissipation. Specifically, the size of the insertion groove 31 needs to match the perforated plate 4 to ensure that the perforated plate 4 can be inserted tightly to prevent dust or debris from entering the housing 1. At the same time, the front end of the retaining strip 3 is flush with the side of the housing 1 with the wire through hole 12, and the end of the retaining strip 3 is flush with the side of the housing 1 with the insertion hole 11. The front end of the retaining strip 3 has a bevel 32, which is used to guide the perforated plate 4. The bevel 32 makes it easier for the perforated plate 4 to be inserted between the retaining strips 3, improving the convenience of installation.
[0033] The inner wall of the housing 1 is provided with several heat dissipation fins 6. The heat dissipation fins 6 are square-shaped and are spaced apart along the extension direction of the retaining strip 3. The inner wall of the heat dissipation fins 6 is in contact with the outer wall of the switch body 2, and the outer wall of the heat dissipation fins 6 is in contact with the inner wall of the housing 1. The arrangement of the heat dissipation fins 6 further increases the heat dissipation area and improves the heat dissipation effect. The heat dissipation fins 6 can be made of materials with good thermal conductivity, such as aluminum alloy. The square-shaped structure of the heat dissipation fins 6 can better fit with the switch body 2 and the housing 1, increasing the heat transfer path. The outer wall of the switch body 2 is provided with a limiting frame 23. When the limiting frame 23 is in contact with the heat dissipation fin 6 closest to the insertion port 11, the switch body 2 is inserted into place. The setting of the limiting frame 23 ensures the accuracy and stability of the insertion of the switch body 2 and avoids affecting the normal use of the switch due to incomplete insertion. The limiting frame 23 can be integrally formed with the switch body 2, or it can be fixed to the switch body 2 by welding or bolt connection.
[0034] A heat dissipation space exists between the heat dissipation fins 6 and the heat dissipation vents 13. The perforated plate 4 is separated from the heat dissipation fins 6. This allows the heat generated by the switch body 2 to flow freely within the heat dissipation space, further improving heat dissipation efficiency. The size of the heat dissipation space can be adjusted according to design requirements by changing the thickness of the housing 1 or the thickness of the perforated plate 4 to ensure that heat can be dissipated smoothly. The separation of the perforated plate 4 from the heat dissipation fins 6 avoids affecting the heat dissipation effect due to contact and also ensures that the heat dissipation fins 6 will not be deformed by impact from the perforated plate 4.
[0035] On one side of the housing 1 with the wire through-hole 12, there are two sets of limiting tubes spaced apart along the thickness direction of the housing 1. Each set of limiting tubes consists of at least three limiting tubes. On the inner side of each of the two pull plates 5, there is a set of limiting posts. The two sets of limiting posts correspond to the two sets of limiting tubes, and each set of limiting posts consists of at least three limiting posts. The number of limiting posts 50 is the same as the number of limiting tubes 14, and the limiting posts 50 are fitted into the limiting tubes 14. When the limiting posts 50 are inserted into the limiting tubes 14, the perforated plate 4 is installed in place, improving the stability of the perforated plate 4 installation and preventing shaking or displacement during use. Furthermore, the limiting posts 50 and the limiting tubes 147 can magnetically attract each other, significantly improving the fixing effect on the perforated plate 4.
[0036] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
