Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1

[0051] This embodiment provides a locking control system for a marine contactor, as shown in the attached diagram. Figures 1-7 As shown, it includes:

[0052] Input power: The input power here is the power supply for the contactor. It can be AC220V or AC380V, which can be adjusted according to actual needs by those skilled in the art.

[0053] The rectifier module 19 includes a rectifier circuit, which can be either half-wave or full-wave rectifier, and those skilled in the art can adjust it according to actual needs. However, it should be noted that because the current passing through the contactor is relatively large, a high-power diode is required to meet this requirement. The specific structure can be found in Chinese Utility Model Patent, Publication No.: CN222029017U.

[0054] The KM1 auxiliary contact 20 is also modular and is fixed to the contactor.

[0055] Regarding the KM1 coil, it should be noted that the KM1 auxiliary contact 20 is normally closed, and the KM1 auxiliary contact 20 and the KM1 coil are interlocked. That is, when the KM1 auxiliary contact 20 is working, the KM1 coil is not working; when the KM1 coil is working, the KM1 auxiliary contact 20 is not working. This is existing technology, so it will not be described in detail in this embodiment.

[0056] The drive assembly 16 includes a drive source EV and a locking tongue 162. The drive source EV drives the locking tongue 162 to move. When the drive source EV is working, it drives the locking tongue 162 to move; conversely, when the drive source EV is not working, the locking tongue 162 returns to its original position. The locking tongue 162 cooperates with the bracket 21. Here, the locking tongue 162 can be directly connected to the bracket 21 to form a connection between the two. The locking tongue 162 can also be connected to the bracket 21 through other transmission components to ultimately lock the bracket 21. When the bracket 21 is in the open state, the locking tongue 162 extends into the movement trajectory of the bracket 21, preventing the bracket 21 from performing a closing operation, thus locking the bracket 21. Here, the drive source EV can be an electromagnetic module, a motor, or other drive structure.

[0057] The input power supply, rectifier module 19, and KM1 coil are connected to form a first electrical circuit; the input power supply, rectifier module 19, KM1 auxiliary contact 20, and drive source EV are connected to form a second electrical circuit.

[0058] When the first electrical circuit is working, the KM1 coil actuates, causing the bracket 21 to move, and the contactor is in the closed state; the second electrical circuit is not working. When the KM1 coil actuates, the KM1 auxiliary contact 20 does not work, causing the drive source EV to also not work.

[0059] The first electrical circuit is not working, meaning the KM1 coil is not working, and the contactor is in the open state. In the corresponding state, the KM1 auxiliary contact 20 works, causing the second electrical circuit to work. At this time, the drive source EV is activated, the locking tongue 162 moves, and the locking tongue 162 cooperates with the bracket 21 to lock the bracket 21.

[0060] This control system, through the switching between the first and second electrical circuits, controls the circuit to be in the open state, effectively locking the bracket 21 with the locking tongue 162 to prevent malfunction. This control system, based on the existing contactor structure with appropriate improvements, is simple in structure and easy to install.

[0061] Specifically, as shown in the attached document Figures 1-2 , Figure 7As shown, it also includes a current-limiting module R1, which is connected in series in the second electrical circuit. The current-limiting module R1 limits the current, ensuring stable operation of the drive source EV. In this embodiment, the current-limiting module R1 uses a high-power resistor for voltage reduction, thereby meeting the power supply requirements of the drive source EV. Here, the current-limiting module R1 mainly addresses the power supply issue when the drive component 16 is an electromagnetic lock; when the drive source EV is a motor, it can also be directly powered. Alternatively, other voltage reduction methods can be used, or the power supply voltage of the drive source EV can be changed.

[0062] Specifically, as shown in the attached document Figures 1-2 As shown, the system also includes a housing 12. The top surface of the housing 12 has a first mounting position 121 and a second mounting position 122. The rectifier module 19 is mounted at the first mounting position 121, and the KM1 auxiliary contact 20 is mounted at the second mounting position 122. The first mounting position 121 and the second mounting position 122 facilitate the installation and fixation of the rectifier module 19 and the KM1 auxiliary contact 20, making installation more convenient. Here, the first mounting position 121 and the second mounting position 122 are sliding groove-type fixing structures.

[0063] Specifically, as shown in the attached document Figures 1-2 As shown, the current limiting module R1 and the drive source EV are mounted on the side of the housing 12. This side mounting allows for better layout, making overall installation more convenient, improving the overall aesthetics, and simplifying wiring. Here, "side" specifically refers to the long side of the housing 12.

[0064] Specifically, the current limiting module R1, the driver EV, and the housing 12 are connected by bolts, snap-fit ​​connections, or adhesive connections. Different connection methods can all achieve a secure connection. Those skilled in the art can adjust the connection method according to actual needs. For example, when the connection method is bolted, the bolt passes through the current limiting module R1 and is fixed to the housing 12. In this case, the housing 12 has holes for the bolt to mate with. Alternatively, an adhesive method can be used, where the current limiting module R1 and the driver EV are attached to the long side of the housing 12 using 3M adhesive or strong adhesive.

[0065] Specifically, as shown in the attached document Figures 1-2As shown, a wiring area 123 is provided on the side of the housing 12. In this embodiment, the contactor is designed with electrical connection between the KM1 auxiliary contact 20 and the KM1 coil. Regarding the rectifier module 19, KM1 auxiliary contact 20, current limiting module R1, and drive source EV in this embodiment, the rectifier module 19 and KM1 auxiliary contact 20 are fixed to the top surface of the housing 12, and the current limiting module R1 and drive source EV are fixed to the long side surface of the housing 12. The rectifier module 19, KM1 auxiliary contact 20, current limiting module R1, and drive source EV are connected by wires, which can be routed through the wiring area 123. In addition, a wire groove can be fixed to the outer surface of the housing 12 for wire routing, improving the overall aesthetics.

[0066] Specifically, as shown in the attached document Figures 1-2 As shown, the drive assembly 16 is an electromagnetic lock, the drive source EV is the electromagnetic part of the electromagnetic lock, and the latch 162 is part of the electromagnetic lock. Using an electromagnetic lock makes operation more convenient, as the control unit and the contactor circuit can work together to achieve the desired coordination. Alternatively, the drive source EV can be a motor, etc. In this embodiment, the electromagnetic lock is fixed to the long side of the contactor; this fixing method can be a bolt connection, an adhesive connection, or a snap-fit ​​connection.

[0067] Specifically, as shown in the attached document Figure 7 As shown, the circuit connection is as follows: the input power supply includes terminals A1 and A2; the rectifier module 19 includes four diodes, namely D1, D2, D3, and D4, which are connected in combination to form a rectifier circuit. This is existing technology and will not be described in detail in this embodiment. Terminal A1 is electrically connected to the negative terminal of diode D3 and the positive terminal of diode D1. Terminal A2 is electrically connected to the positive terminal of diode D2 and the negative terminal of diode D4. In the electrical schematic diagram, the current limiting module is represented by R1, and the driving source is represented by EV. The KM1 auxiliary contact 20, the current limiting module R1, and the driving source EV are connected in series, with the current limiting module R1 located between them. The other end of the KM1 auxiliary contact 20 is electrically connected to the negative terminals of diodes D1 and D2, and the other end of the driving source EV is electrically connected to terminal A2. At this time, the input power supply, rectifier module 19, KM1 auxiliary contact 20, driving source EV, and current limiting module R1 are connected to form a second electrical circuit.

[0068] One end of the KM1 coil is electrically connected to the negative terminals of diodes D1 and D2, respectively, and the other end of the KM1 coil is electrically connected to the positive terminals of diodes D3 and D4, respectively. At this time, the input power supply, rectifier module 19, and KM1 coil are connected to form the first electrical circuit.

[0069] Specifically, as shown in the attached document Figures 1-6As shown, it also includes a reaction mechanism, which includes two connecting rods 11 connected by a connecting shaft, creating a linkage between the two connecting rods 11. In addition, the reaction mechanism includes a torsion spring that cooperates with the connecting rod 11; this is existing technology and will not be described in detail in this embodiment. The connecting rod 11 is connected to the bracket 21, and the connection between the connecting rod 11 and the bracket 21 allows for movement. When the contactor opens, the torsion spring drives the bracket 21 to reset via the connecting rod 11, causing the bracket 21 to move vertically up and down, achieving the opening and closing effects; this is also existing technology and will not be described in detail. In existing contactors, when used on ships (where waves create vibrations during navigation), the bracket 21 may reciprocate vertically under the force of vibration, posing a risk of misoperation.

[0070] The interlocking component 13, in cooperation with the connecting rod 11, forms a first locking part 14 and a second locking part 15. These two locking parts create two locking regions, achieving a secure connection between the interlocking component 13 and the connecting rod 11. Compared to a single locking region, which cannot provide omnidirectional locking, the two locking regions offer a better locking effect. The first locking part 14 and the second locking part 15 can have the same structure or different structures, depending on actual needs. The first locking part 14 and the second locking part 15 form the connection and fixation between the connecting rod 11 and the interlocking component 13. The interlocking component 13 is provided with an interlocking hole 131. In this embodiment, the interlocking component 13 is located on the short side of the housing 12, and the latch 162 moves towards the short side of the housing 12, thereby achieving the cooperation effect between the latch 162 and the interlocking component 13.

[0071] In the open state, the locking tongue 162 extends to the interlocking hole 131, engaging with it. At this time, the locking tongue 162 is positioned on the movement trajectory of the side wall of the interlocking hole 131. When the interlocking member 13 moves, the locking tongue 162 restricts the rotation of the interlocking member 13, thus achieving the effect of locking the interlocking member 13. In the closed state, the locking tongue 162 extends out of the interlocking hole 131, meaning it is reset. The locking tongue 162 is no longer positioned on the movement trajectory of the side wall of the interlocking hole 131. When the interlocking member 13 moves, the locking tongue 162 does not restrict its movement. At this time, the connecting rod 11 drives the interlocking member 13 to move, allowing the bracket 21 to move up and down. Alternatively, the locking tongue 162 can be directly connected to the bracket 21 to form a locking effect, or when the bracket 21 is in the open state, the locking tongue 162 extends onto the movement trajectory of the bracket 21, preventing the bracket 21 from performing a closing operation.

[0072] With this structural design, a single contactor can achieve a self-locking effect through the drive assembly 16. That is, when in the open state, it is locked by the interlocking element 13, thereby restricting the movement of the bracket 21 and achieving a locking effect. This structure is simple, has a good locking effect, avoids malfunction of the contactor under vibration, and improves the stability of the contactor operation.

[0073] Specifically, as shown in the attached document Figures 1-6 As shown, one of the interlocking member 13 and the connecting rod 11 is provided with a limiting post 17, and the other of the interlocking member 13 and the connecting rod 11 is provided with a limiting hole 18 that mates with the limiting post 17. When the interlocking member 13 is provided with the limiting post 17, the connecting rod 11 is provided with the limiting hole 18; conversely, when the interlocking member 13 is provided with the limiting hole 18, the connecting rod 11 is provided with the limiting post 17. The connection between the limiting post 17 and the inner wall of the limiting hole 18 has at least one planar connection point. Specifically, this planar connection point is where the planes abut against each other; that is, the outer wall of the limiting post 17 has a plane, and the inner wall of the limiting hole 18 has a plane, and the two planes abut against each other to form a planar connection point. When the planes abut against each other, a limiting and fixing effect is achieved, and the interlocking member 13 and the connecting rod 11 are fixedly connected. Furthermore, the limiting post 17 can be a regular triangular prism, with the limiting hole 18 having a corresponding shape; the limiting post 17 can also be a regular square prism, or even a regular hexagonal prism. The limiting post 17 and the limiting hole 18 cooperate to form the first locking part 14. The cooperation between the limiting post 17 and the limiting hole 18 creates a limiting and locking effect. Alternatively, other fixing methods can be used, such as bolt fixing, rivet fixing, etc.

[0074] Specifically, it also includes a fastening assembly, which passes through the interlocking member 13 and connects to the connecting rod 11. The fastening assembly, interlocking member 13, and connecting rod 11 cooperate to form a second locking part 15. The fastening assembly better achieves the connection and fixation effect between the interlocking member 13 and the connecting rod 11.

[0075] Specifically, as shown in the attached document Figures 3-6 As shown, the interlocking component 13 is provided with a guide post 132, and the connecting rod 11 is provided with a protrusion 111. The guide post 132 is sleeved on the protrusion 111, forming a pre-positioning and fixing effect between the guide post 132 and the protrusion 111. The fastening component passes through the guide post 132 and connects with the protrusion 111. The guide post 132 and the protrusion 111 form a positioning and fixing effect.

[0076] Specifically, as shown in the attached document Figure 4 As shown, the fastening assembly includes a guide sleeve 191 and a fastener 192. The guide sleeve 191 is housed within the guide post 132, and the fastener 192 passes through the guide sleeve 191 and connects to the protrusion 111. The guide sleeve 191 further enhances the fastening effect. A washer 193 can also be added between the fastener 192 and the guide sleeve 191. The fastener 192 can be a bolt, specifically a self-tapping screw.

[0077] Specifically, the connection between the guide sleeve 191 and the guide post 132 is a stepped connection. The stepped connection provides a positioning and fixing effect for the guide sleeve 191, preventing the guide sleeve 191 from moving.

[0078] Specifically, as shown in the attached document Figures 3-6 As shown, the interlocking hole 131 has a notch 133. The notch 133 is provided here to better achieve the cooperation effect between the interlocking hole 131 and the bolt 162.

[0079] Specifically, the cross-section of the latch 162 can be circular, square, triangular, or irregular in shape, and those skilled in the art can adjust it according to actual needs.

[0080] Specifically, as shown in the attached document Figures 3-6 As shown, the interlocking component 13 is provided with a guide surface 134, which guides the bolt 162 into the interlocking hole 131. The guide surface 134 is provided so that when the bolt 162 just abuts against the guide surface 134, the bolt 162 can enter the interlocking hole 131 by sliding the guide surface 134, thus forming a locking effect.

[0081] Specifically, as shown in the attached document Figure 1 Appendix Figures 3-6 As shown, the interlocking component 13 is provided with several reinforcing ribs 135, which improve the overall strength of the interlocking component 13.

[0082] Specifically, the interlocking component 13 is injection molded as a single piece. This single-piece injection molding design makes the processing of the interlocking component 13 more convenient. The interlocking component 13 can be designed with various features to meet different mating requirements. Compared to metal parts, plastic parts are easier to process and provide better interlocking performance. Here, the interlocking component 13 can be made of high-strength plastic.

[0083] Specifically, as shown in the attached document Figure 1 , Figure 3 As shown, the lines connecting the imaginary center of the first locking part 14, the imaginary center of the second locking part 15, and the imaginary center of the interlocking hole 131 form a triangle. When locked, the triangle structure is more stable and can achieve a better locking effect, preventing the bracket 21 from moving.

[0084] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
