Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of double-pole double-throw switch devices, in particular to a self-restoring double-pole double-throw mechanical switch. BACKGROUND

[0002] As a key element that can realize two-way circuit switching control, the double-pole double-throw mechanical switch is widely used in many fields such as communication equipment, test instruments, industrial control systems, etc. The traditional double-pole double-throw mechanical switch mostly adopts manual operation or single electromagnetic driving structure, which has the following disadvantages:

[0003] The switch switched manually needs manual intervention to complete circuit switching, and cannot realize remote or automatic control in an automatic control system, and the operation convenience is poor; although the switch driven by electromagnet can realize automatic switching, it usually relies on the on-off control of a single coil and the use of elastic elements such as springs, and the magnetic driving force is unstable in the switching process, and the switching jam phenomenon is easy to occur.

[0004] The traditional switch lacks a reliable self-restoring mechanism and cannot automatically reset to the initial working state after power failure, which requires additional reset structure or manual operation, increasing the design complexity and use cost of the device. In addition, the magnetic circuit design of the existing switch is unreasonable, the magnetic conduction efficiency between the coil assembly and the magnetic component is low, resulting in high driving energy consumption, slow switching response speed, and difficulty in meeting the requirements of high-precision devices for the rapidity and stability of switch action.

[0005] At the same time, the copper sheet on the switch is mostly fixed and installed by screws, and when the switch is used for a long time, the copper sheet is easy to deform, and short circuit burning may also occur during use. The copper sheet installed by screws needs to be disassembled with the aid of a screwdriver and the like, and the screws are easy to slip, and after slipping, the copper sheet cannot be replaced, which is easy to cause waste of the switch. SUMMARY

[0006] In order to improve the convenience of the self-restoring double-pole double-throw mechanical switch in the operation process, the present application provides a self-restoring double-pole double-throw mechanical switch.

[0007] The present application provides a self-restoring double-pole double-throw mechanical switch, which adopts the following technical scheme:

[0008] The utility model provides a self -recovery shape's double -pole double -throw mechanical switch, including switch panel, radio frequency connector is connected on the switch panel, the switch switch board is movably installed on the switch panel, the copper sheet is installed on the switch switch board, the fixed column is connected on the switch panel, the magnetic separation board is installed on the fixed column, the transmission magnetic board is installed on the magnetic separation board, the circuit board is installed on the transmission magnetic board, the first coil assembly and the second coil assembly are installed on the transmission magnetic board, the first coil assembly is isolated with the transmission magnetic board through the magnetic separation board, the second coil assembly is in contact with the transmission magnetic board directly, the first coil assembly and the second coil assembly are set up in the top of the switch switch board and are arranged respectively corresponding two ends of the switch switch board, the transmission magnetic board adsorbs the permanent magnet, and the permanent magnet is arranged between the first coil assembly and the second coil assembly.

[0009] By adopting the above technical scheme, the magnetic drive system is constructed by the cooperation of the permanent magnet and the double coil assembly, the magnetic circuit regulation and control of the magnetic separation plate and the transmission magnetic plate are combined, the magnetic drive and self-recovery reset of the switch switch board are realized. Compared with the traditional manual switch, the circuit switching can be completed without manual intervention; compared with the single coil drive structure, the magnetic attraction and magnetic repulsion of the double coils improve the fluency of the switching action, and the setting of the permanent magnet and the magnetic separation plate guarantees the automatic reset function after power failure, which greatly improves the convenience and use reliability of the switch operation.

[0010] In a specific implementation scheme, the first coil assembly includes a coil core, a coil is wound on the coil core, the coil is composed of a copper wire, a first pin and a second pin are installed on the coil core, the first pin and the second pin pass through the transmission magnetic plate and the circuit board and extend above the circuit board, the ends of the copper wire of the coil are connected to the first pin and the second pin respectively, the first pin is connected to a positive potential, the second pin is connected to a zero potential, and the pin potential of the second coil assembly is opposite to that of the first coil assembly.

[0011] By adopting the above technical scheme, when the first coil assembly is powered, the first pin is connected to a positive potential and the second pin is connected to a zero potential, and the coil core generates N-pole magnetism. Since the pin potential of the second coil assembly is opposite, the coil core of the second coil assembly generates S-pole magnetism. The double coil assembly forms a magnetic field with opposite polarity through the potential difference, which can generate clear magnetic attraction and magnetic repulsion force on the switch switch board, providing stable and controllable driving force for the switch switch, avoiding the switching jamming problem caused by unstable magnetism in traditional single coil drive. At the same time, the design of the pins passing through the circuit board facilitates the connection with the external circuit, improving the assembly convenience and circuit connection reliability of the switch as a whole.

[0012] In one specific implementation, the permanent magnet has two poles at two ends, one end being N pole and the other end being S pole, and the N pole of the permanent magnet is connected with the magnetic transmission plate.

[0013] By adopting the above technical solution, the N pole of the permanent magnet is connected with the magnetic transmission plate, so that the magnetic field of the permanent magnet can be stably transmitted to the magnetic transmission plate, and then act on the second coil assembly. Since the second coil assembly is directly in contact with the magnetic transmission plate, under the unpowered state, the magnetic field of the permanent magnet transmitted by the magnetic transmission plate makes the core of the second coil assembly have magnetism, and forms stable adsorption with the switch switching plate, thereby ensuring the reliability of the initial state of the switch. When powered, the magnetic field of the double coil assembly cooperates with the magnetic field of the permanent magnet, thereby further enhancing the switching driving force. After power-off, the magnetic field of the permanent magnet can quickly reset the switch switching plate, thereby ensuring the stable implementation of the self-recovery function and avoiding the reset failure problem caused by the dependence on the easily-worn elements such as springs.

[0014] In one specific implementation, the switch panel is provided with a fixing seat, a rotating rod is rotatably installed on the fixing seat, and the switch switching plate is installed on the rotating rod. The switch switching plate is made of a material capable of being magnetically adsorbed, and the copper sheet is installed on the bottom surface of the switch switching plate by screws.

[0015] By adopting the above technical solution, the cooperation of the fixing seat and the rotating rod provides stable rotating support for the switch switching plate, so that the switch switching plate can be flexibly rotated around the rotating rod, thereby ensuring the smoothness of the switching action. The switch switching plate is made of a magnetically adsorbed material, which can effectively respond to the magnetic force of the double coil assembly and the permanent magnet, thereby ensuring the driving efficiency. The copper sheet is installed by screws, so that the preliminary fixation of the copper sheet can be realized when the copper sheet does not have serious damage or deformation. The screw connection mode has low cost and convenient assembly, and takes into account the basic use requirements of the switch.

[0016] In one specific implementation, the switch switching plate is provided with a clamping groove and a locking groove, the clamping groove and the locking groove are communicated, a first clamping block is installed on the switch switching plate, the first clamping block is arranged in the clamping groove, a clamping opening for clamping the first clamping block is formed in the copper sheet, and a locking plate for blocking the copper sheet on the switch switching plate is detachably installed on the switch switching plate.

[0017] By adopting the above technical solution, the clamping groove provides an installation and positioning space for the copper sheet, and the cooperation of the first clamping block and the clamping opening of the copper sheet can realize the rapid preliminary positioning of the copper sheet, thereby avoiding the deviation of the copper sheet during the installation process and improving the assembly efficiency. The locking groove provides an installation position for the locking plate, and the communication between the clamping groove and the locking groove enables the locking plate to directly block the copper sheet in the clamping groove after installation, thereby further stabilizing the copper sheet. The detachable design of the locking plate facilitates the quick disassembly and replacement of the locking plate when the copper sheet is damaged, thereby reducing the maintenance cost and improving the use flexibility of the switch.

[0018] In one specific implementation, a sliding groove is formed on the lock plate, a clamping plate is slidably connected to the lock plate through the sliding groove, a lock block is installed on the switch switching plate, and a lock opening is formed on the lock block for clamping the clamping plate.

[0019] By adopting the above technical scheme, the sliding groove provides sliding guidance for the clamping plate, so that the clamping plate can stably move along the lock plate; when the clamping plate is clamped into the lock opening of the lock block, the lock plate and the switch switching plate can be firmly locked, avoiding loosening of the lock plate due to vibration and other factors during use of the switch, thereby ensuring the stability of the copper sheet fixation; compared with the traditional screw fixation, the locking structure can be disassembled and assembled without the aid of tools, and the operation is more convenient, and the problem of copper sheet replacement caused by screw slipping is avoided, thereby prolonging the service life of the switch.

[0020] In one specific implementation, a guide rod is installed on the switch switching plate, a movable block is slidably installed on the guide rod, a spring is sleeved on the guide rod, one end of the spring is connected with the movable block, and the other end of the spring is connected with the switch switching plate, a push block is installed on the movable block, one end of the push block away from the movable block extends into the lock slot, a fixed plate is installed on the switch switching plate, a lifting block is slidably installed on the fixed plate, a connecting rod is hingedly connected to the lifting block, one end of the connecting rod away from the lifting block is hingedly connected with the movable block, and a pressing plate for pressing the copper sheet is connected to the lifting block.

[0021] By adopting the above technical scheme, the guide rod provides sliding guidance for the movable block, ensuring stable movement of the movable block in a fixed direction; the elastic force of the spring can push the movable block to reset after the lock plate is disassembled, thereby driving the subsequent components to reset and preparing for the next copper sheet installation; the push block extends into the lock slot, and when the lock plate is pushed into the lock slot, the push block can be pushed to move the movable block, the movable block drives the lifting block to slide along the fixed plate through the connecting rod, and the lifting block drives the pressing plate to press the copper sheet downward. The linkage structure realizes synchronous completion of the lock plate installation and the copper sheet pressing, without the need for additional operation, further improving the convenience of copper sheet installation and the reliability of pressing, and avoiding the problem of poor circuit contact caused by loose installation of the copper sheet.

[0043] When first pin 713 is connected to positive potential, and second pin 714 is connected to zero potential, N-pole magnetism appears in coil core 711, the pin potential of second coil assembly 72 is completely opposite, so the core of second coil assembly 72 will appear S-pole magnetism.
