Description

Technical Field

[0001] This utility model belongs to the field of magnetic switch technology, specifically relating to a PCB modular magnetic switch. Background Technology

[0002] With the rapid development of electronic technology, electronic switches are playing an increasingly important role in circuit design. Traditional electronic switches, such as relays, while capable of controlling the on / off state of circuits, suffer from problems such as large size, high cost, and inconvenient installation when facing diverse and complex circuit control needs. Especially when multiple circuits need to be controlled or high voltage withstand values ​​are required, traditional relays often need to be connected in parallel or series, which not only increases the size and cost of the product but also reduces the reliability and maintainability of the system. Magnetic switches have emerged as a result, but existing magnetic switches have certain drawbacks. For example, Chinese patent CN 222365526 ​​U discloses a magnetic switch that is easy to assemble. This switch uses a positioning plate, a limiting block, an upper fixing block, a lower fixing block, and a threaded rod. The positioning plate and the limiting block are used for positioning. The limiting block is inserted into the positioning plate, and when force is applied downwards, the limiting plate is inserted into the limiting groove. At the same time, the limiting rod extends into the mounting block, which allows the top shell and the outer shell to close. Then, the threaded rod and the nut are used to fix the outer shell and the top shell, which is convenient for splicing. Although this device has a certain degree of convenience in assembly, its modularity is low, so the difficulty of inspection and maintenance is relatively high, and the inspection and maintenance efficiency is low.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0021] A modular magnetic control switch for PCB includes a PCB component 1. The top of the PCB component 1 is open to form a slot 12, and two through-holes 13 are symmetrically opened on the PCB component 1. The slot 12 is located between the two through-holes 13 and the through-holes 13 communicate with the slot 12. A detachable conductive component 2 is screwed into the interior of each of the two through-holes 13. A detachable magnetic control component 3 is installed inside the slot 12. The magnetic control component 3 includes a housing part and two conductive seats 36. The two conductive seats 36 are both disposed on the housing part, and a spring 37 is fixedly connected to the opposite side of each of the two conductive seats 36. A connecting contact point 38 is fixedly connected to the free end of the spring 37. There is a gap between the two connecting contact points 38, and one end of the conductive component 2 contacts the connecting contact point 38.

[0022] With the above technical solution, when personnel need to use the device, the housing part is inserted into the slot 12 on the PCB part 1, and the conductive part 2 is inserted into the connection hole 13 on the PCB part 1. The conductive part 2 is rotated to screw the conductive part 2 onto the PCB part 1 until the conductive part 2 is connected to the conductive base 36. Then, the two conductive parts 2 are connected to the circuit to be controlled. When it is necessary to control the circuit, the magnet is moved to one side of the housing part, and the two connecting contact points 38 are attracted by the magnet, so that the two connecting contact points 38 are connected, and the two springs 37 are connected, so that the circuit is open. When personnel need to control the circuit to be disconnected, the magnet is removed, the connecting contact points 38 are reset, the two connecting contact points 38 are separated, and the two springs 37 are separated, so that the circuit is disconnected.

[0023] After the housing part is installed into the slot 12, in order to prevent the housing part from accidentally falling off, such as Figures 1-3 , Figure 5 As shown, the housing part has symmetrical recesses on both sides to form positioning holes 35, and the PCB part 1 has symmetrical recesses on both sides to form side grooves 14. Two connecting holes 13 are located between the two side grooves 14. A deformable positioning plate 15 is provided inside the side groove 14. The positioning plate 15 protrudes outward on the side facing the housing part to form a positioning head 17. The positioning head 17 matches the positioning hole 35.

[0024] In this embodiment, before the personnel insert the housing part into the slot 12, they pull the positioning plate 15 to deform the positioning plate 15 and move the positioning head 17 to the outside of the slot 12. Then, the housing part is inserted into the slot 12 on the PCB component 1. After the housing part is inserted, the positioning plate 15 is released and moves back, thereby driving the positioning head 17 to move and insert the positioning head 17 into the positioning hole 35 on the housing part, thereby fixing the housing part and preventing the housing part from accidentally falling off the PCB component 1, thus making the housing part more stable after installation.

[0025] Furthermore, in this utility model, to make the positioning plate 15 easy to pull, such as... Figures 1-3 As shown, the positioning plate 15 is recessed on the side away from the positioning head 17 to form a groove 16.

[0026] In this embodiment, when a person needs to pull the positioning plate 15, the positioning plate 15 is easily pulled by the groove 16.

[0027] Specifically, in one embodiment, regarding the aforementioned PCB component 1, as... Figures 1-3 As shown, PCB component 1 includes PCB board 11, slot 12 is formed on the top of PCB board 11, and two connecting holes 13 are formed on the symmetrical sides of PCB board 11.

[0028] In this embodiment, when personnel need to install the housing part, they pull the positioning plate 15 to deform the positioning plate 15 and move the positioning head 17 to the outside of the slot 12. Then, the housing part is inserted into the slot 12 on the PCB board 11. After the housing part is inserted, the positioning plate 15 is released and moves back, thereby driving the positioning head 17 to move and insert the positioning head 17 into the positioning hole 35 on the housing part, thereby fixing the housing part to the PCB board 11.

[0029] Furthermore, in this utility model, regarding the aforementioned conductive element 2, as follows: Figure 1 , Figure 2 and Figure 4 As shown, the conductive component 2 includes a protective tube 21, which is detachably screwed into the inside of the connection hole 13, and a wire 22 is fixedly connected inside the protective tube 21.

[0030] In this embodiment, when personnel need to install the conductive component 2, the protective tube 21 is inserted into the connection hole 13 on the PCB board 11, and the protective tube 21 is rotated to install the protective tube 21 onto the PCB board 11, thereby allowing the wire 22 to be installed onto the PCB board 11 and connecting the wire 22 to the conductive base 36.

[0031] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-3 and Figure 5 As shown, the housing includes a protective shell 31. Both sides of the protective shell 31 are recessed to form through holes 32, and the top of the protective shell 31 is open to form a top hole 33. A tempered glass plate 34 is fixedly connected inside the top hole 33. A conductive seat 36 is fixedly connected inside the through hole 32. A positioning hole 35 is formed on the outside of the protective shell 31 and is located on the side adjacent to the through hole 32.

[0032] In this embodiment, when personnel need to install the housing, the protective housing 31 is inserted into the slot 12 on the PCB board 11, and the positioning head 17 engages with the positioning hole 35 on the protective housing 31, thereby making the protective housing 31 more secure after installation. The protective housing 31 supports the conductive base 36, thereby supporting the spring 37 and the connecting contact point 38. Furthermore, the top hole 33 cooperates with the tempered glass plate 34 to facilitate observation of the interior of the protective housing 31.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
