Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a master-slave integrated control combination switch. Background Technology

[0002] In electrical control systems, combination switches are a common component for centralized control of multiple circuits. They are widely used in industrial equipment, building electrical systems, smart homes, and other fields. Their core function is to integrate multiple switch units to achieve unified management and control of different branch circuits, thereby simplifying circuit layout and improving ease of operation.

[0003] While some existing combination switches attempt to integrate the main switch and branch switches, the two are often connected by a single wire or a simple copper sheet. This not only limits the current carrying capacity and makes them prone to poor contact, oxidation, and aging after long-term use, but also makes it difficult to achieve stable on / off control of the overall circuit by the main switch and precise control of individual branches by the branch switches, resulting in chaotic control logic. In addition, the switching units of traditional combination switches are mostly exposed or have simple protection designs. In environments such as industrial workshops and home kitchens, accidental touch by personnel or collision with foreign objects can easily cause the switches to malfunction, leading to short circuits, equipment failures, or even electric shock accidents.

[0004] Therefore, a combined switch with master-slave control is proposed. Utility Model Content

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A main switch and branch switch combination switch includes a support base 1. A combination switch assembly 2 is provided on the top of the support base 1. The combination switch assembly 2 includes a main switch 201 and multiple branch switches 202. The main switch 201 and multiple branch switches 202 are connected by two common long copper legs 203. A terminal block 204 is provided on the front side of the bottom of the branch switch 202. A back plate 3 is fixedly connected to the rear side of the top of the support base 1. Multiple T-shaped slots 4 are opened on the top of the back plate 3. A T-shaped block 5 is fixedly connected to the rear side of the branch switch 202. The T-shaped block 5 is used in conjunction with the T-shaped slot 4. Side plates 6 are fixedly connected to both sides of the top of the support base 1, and the side of the side plate 6 closest to the main switch 201 and the branch switches 202 are respectively attached to them. An anti-accidental touch component 7 is provided on the top of the side plate 6.

[0028] In this embodiment: by setting up the combination switch assembly 2, the main switch 201 can realize unified on / off control of the entire circuit, the branch switches 202 can accurately control their respective branches, the control logic is clear, the two common long copper legs 203 are used to connect the main switch 201 and the branch switches 202, which can improve the current carrying capacity and reduce the risk of poor contact and oxidation aging. The side plate 6 can laterally limit the main switch 201 and the branch switches 202 to ensure that the combination switch assembly 2 is installed firmly. The T-shaped block 5 can slide with the T-shaped groove 4, which facilitates the flexible disassembly and assembly of the combination switch assembly 2, thereby improving the use effect.

[0029] Specifically, such as Figure 3 As shown, the anti-accidental touch component 7 includes a fixing plate 701. The number of fixing plates 701 is set to two, and the two fixing plates 701 are respectively fixedly connected to the front and rear sides of the top of the left side plate 6. A rotating rod 702 is rotatably connected between the two fixing plates 701 through a bearing.

[0030] Specifically, such as Figure 3 As shown, a cover plate 703 is fixedly sleeved on the surface of the rotating rod 702. The cover plate 703 is made of metal and its surface is coated with an insulating coating.

[0031] Specifically, such as Figure 3As shown, a limiting plate 704 is fixedly connected between the two fixed plates 701, and the number of limiting plates 704 is set to two. The two limiting plates 704 are located on both sides of the rotating rod 702.

[0032] Specifically, such as Figure 3 As shown, magnetic blocks 705 are embedded in the top and bottom of the limiting plate 704, and the magnetic blocks 705 are magnetically connected to the cover plate 703.

[0033] In this embodiment: by setting up an anti-accidental touch component 7, the fixing plate 701 serves as the mounting base for the anti-accidental touch component 7. The two fixing plates 701 are respectively fixed to the front and rear sides of the top of the left side plate 6, providing a stable support point for the rotating rod 702. The rotating rod 702 is rotatably connected to the fixing plate 701 through a bearing, allowing the cover plate 703 to open and close flexibly, meeting the opening requirements during operation and the protection requirements when idle. The cover plate 703 is made of metal and coated with an insulating coating. When closed, it can physically block the main switch 201 and the branch switch 202, preventing personnel from... Accidental touch or collision with foreign objects can cause the switch to malfunction. The insulating coating can enhance electrical safety and reduce the risk of electric shock. The limit plate 704 is located on both sides of the rotating rod 702 to limit the rotation angle of the cover plate 703, so as to prevent the cover plate 703 from rotating excessively and affecting its use or interfering with other components, and to ensure the accuracy of the opening and closing position of the cover plate 703. The magnetic block 705 is embedded on the top of the limit plate 704 and is connected to the cover plate 703 by magnetism. It can attract and fix the cover plate 703 after it is opened or closed, preventing the cover plate 703 from shaking randomly and ensuring that the protective state is stable or the operating space is not disturbed.

[0034] Specifically, such as Figure 1 As shown, a front baffle 8 is fixedly connected to the front side of the top of the support base 1, and the interior of the front baffle 8 has a groove for use with the wiring terminal 204.

[0035] Specifically, such as Figure 4 As shown, the top of the back plate 3 is provided with an anti-detachment plate 9, the bottom of the anti-detachment plate 9 is fixedly connected with a locking block 10, and the top of the back plate 3 is provided with a locking groove 11, which is used in conjunction with the locking block 10.

[0036] Specifically, such as Figure 5 As shown, a positioning rod 12 runs through the interior of the back plate 3 and extends into the interior of the slot 11. The slot 10 has a positioning groove 13 inside that works in conjunction with the positioning rod 12.

[0037] Specifically, such as Figure 4 , Figure 5As shown, a mounting groove 14 is provided on the right side of the back plate 3. The positioning rod 12 is located inside the mounting groove 14. A pull block 15 is fixedly connected to the outside of the positioning rod 12. A fastening spring 16 is sleeved on the surface of the positioning rod 12, and the two ends of the fastening spring 16 are fixedly connected to the pull block 15 and the inner wall of the mounting groove 14, respectively.

[0038] In this embodiment: With the above settings, the front baffle 8 is fixed to the top front side of the support base 1, which can physically shield the wiring terminal 204 at the bottom of the switch 202, preventing external dust, water droplets, metal shavings and other foreign objects from contacting the wiring terminal 204, thus avoiding short circuit oxidation of the wiring terminal 204. The groove is opened inside the front baffle 8 and is adapted to the wiring terminal 204, which can not only reserve a channel for the wires led out from the wiring terminal 204, avoiding poor contact caused by the front baffle 8 squeezing the wires, but also limit and guide the wires, preventing the wires from being pulled by external forces. The anti-detachment plate 9 detaches from terminal 204 without obstructing the terminal 204's operating port, thus not affecting wiring, disconnection, or maintenance. It also limits the top of the branch switch 202, preventing it from detaching from the top of the T-slot 4 during long-term use, ensuring the stability of the branch switch 202's assembly. The locking block 10 engages with the locking slot 11 on the top of the back plate 3, quickly and initially locking the anti-detachment plate 9 onto the top of the back plate 3, achieving pre-installation without tools. Once the locking block 10 is inserted into the locking slot 11, the positioning rod 12 can... The positioning groove 13 of the insert block 10 transforms the initial engagement of the block 10 and the groove 11 into a rigid lock, completely preventing the anti-disengagement plate 9 from loosening or falling off, and avoiding the release switch 202 from dislodging from the T-slot 4 due to external force. The positioning groove 13 is size-matched with the positioning rod 12, providing a precise insertion channel for the positioning rod 12, ensuring a tight fit, limiting the lateral and longitudinal displacement of the block 10 within the groove 11, and ensuring the locking effect. The mounting groove 14 provides a concealed installation space for the positioning rod 12 and the fastening spring 16, preventing the components from being exposed. Damage or dust accumulation can be addressed by the pull block 15, which provides a convenient point of force for the operator. When disassembling the anti-detachment plate 9, pulling the pull block 15 will pull the positioning rod 12 out of the positioning slot 13 without tools, simplifying the disassembly and assembly process of the anti-detachment plate 9 and facilitating the maintenance or replacement of the switch 202. The fastening spring 16 can provide continuous tension for the positioning rod 12, ensuring that the positioning rod 12 does not loosen during long-term use and guaranteeing locking stability. At the same time, in the natural state, the pull block 15 can be pulled to automatically insert the positioning rod 12 into the positioning slot 13, thereby achieving automatic locking of the positioning rod 12.

[0039] Specifically, such as Figure 4 As shown, each of the four corners of the support base 1 is fixedly connected to a connecting plate 17, and each connecting plate 17 has a mounting screw hole 18 inside.

[0040] In this embodiment: Through the above configuration, the connecting plate 17 serves as the connection structure between the support base 1 and the external mounting surface. Its four-corner distribution expands the contact area, evenly distributing the weight of the support base 1 and the components above it, preventing localized deformation. It also adapts to various installation scenarios, including planar and vertical installations, improving installation stability. The mounting screw holes 18 can directly match common mounting screws, allowing for quick and easy fixing of the support base 1 without additional processing. The threaded connection's interlocking structure has strong resistance to loosening, resisting external impacts and vibrations, ensuring the support base 1 is firmly installed for a long time, providing a stable foundation for the subsequent assembly and use of the combination switch assembly 2.

[0041] Working principle: First, place the support base 1 on the mounting surface and screw in the screws through the mounting screw holes 18 of the four corner connecting plates 17 to ensure that the support base 1 is horizontal and stable. Then, align the T-shaped block 5 on the back of the branch switch 202 with the T-shaped groove 4 of the back plate 3 and push it vertically in, so that the main switch 201 and the branch switch 202 are placed against the side plate 6. Next, align the locking block 10 at the bottom of the anti-disengagement plate 9 with the locking groove 11 at the top of the back plate 3 and press it into place. Pull the pull block 15 to compress the positioning rod 12 and tighten the tension spring 16. After releasing, the positioning rod 12 will insert into the positioning groove 13 of the locking block 10, thereby allowing... The position of the anti-detachment plate 9 is fixed to prevent the branch switch 202 from falling out of the T-slot 4. In daily use, the cover plate 703 is rotated. When the main switch 201 is open or closed, all branches of the branch switch 202 can be energized. When the main switch 201 is open, all branches of the branch switch 202 are de-energized. In addition, when the main switch 201 is open or closed, operating a branch switch 202 alone can connect or disconnect the corresponding branch without affecting other branches. After operation, the cover plate 703 is closed so that the magnetic block 705 is attracted and fixed to the cover plate 703, thus realizing the protection against accidental contact.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
