Description

Technical Field

[0001] This utility model relates to the field of overcurrent protection devices, and in particular to a six-column full-phase safety protection device. Background Technology

[0002] An overvoltage protector (OVP) is an electrical safety device used to limit abnormally high voltages in a circuit (such as lightning strikes, switching overvoltages, or power grid failures) to prevent equipment damage. It protects sensitive electronic equipment, power systems, or household appliances by rapidly discharging overvoltages to ground or clamping them to a safe range through a fast response (such as gas discharge, varistors, or semiconductor elements). Common types include surge protectors (SPDs), lightning arresters, and TVS diodes, and are widely used in power systems, communication equipment, and industrial control to ensure stable system operation and extend equipment life.

[0003] A search revealed patent publication number CN217848933U, which discloses a six-post overvoltage protector, relating to the field of overvoltage protectors. The protector includes a mounting base with terminals on its inner side. Connecting wires are mounted on the top of the terminals. A housing is fixed to the mounting base, and a second housing is mounted on top of the first housing. A sealing frame, which mates with the mounting base, is fixed to the bottom of the second housing. Connecting blocks are fixed to the surface of the first housing, and extending slides are provided on the inner side of each connecting block. This invention protects the terminals, reducing wear and corrosion during installation in the external environment, and reducing wear on the connection points between the connecting wires and the terminals during use, effectively ensuring the safety of the connecting wires during energized operation. It also simplifies the installation process of the enclosed housing; when maintenance is needed to check the resistor wiring inside the mounting base, it is not necessary to completely disassemble the six-post overvoltage protector, facilitating operation by staff.

[0004] While existing technologies can achieve a certain voltage protection effect during use, they have drawbacks: the existing protection effect is prone to multi-point conduction and over-protection, leading to overuse and waste. In view of this, we propose a six-column full-phase safety protection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a six-column full-phase safety protection device.

[0006] The technical solution of this utility model is as follows: A six-column full-phase safety protection device includes a housing, a voltage selector, a main body, a mounting groove, a conductor one, and a conductor two. The upper end of the housing is provided with mounting grooves arranged in a linear array. The main body is rotatably installed inside the mounting groove. One side of the mounting groove is provided with a conductor one with an elastic structure. One side of the conductor one is provided with an arc-shaped conductor two. The side of the conductor one away from the conductor two is provided with a buckle. The upper end of the main body is provided with a contact.

[0007] When this device is in use, if a large current enters the main line, the voltage selector can select one of three voltage levels, and then the corresponding relay will be activated, introducing the current into the corresponding part of the device, thus achieving the protection effect. The key feature of this device is the addition of a voltage selector. In addition, the main body rotates into the mounting slot, allowing conductor one and conductor two to conduct. The branch line is directly inserted into the buckle, and the inclined design ensures a stable connection, facilitating the disassembly and maintenance of the main body. This device has the protection effect of voltage selection and the ability to quickly install, disassemble, and maintain the main body, making it highly practical.

[0008] Preferably, a mounting base is provided on one side of the enclosure, and three relays are provided on one side of the voltage selector. A branch line is provided between the relays and the mounting base. The mounting base and relays make the branch line connection more stable and reduce the risk of loosening.

[0009] Preferably, a connector is provided at the top of one side of the branch line, and the outermost width of the connector is greater than the middle width. The widened design of the connector enhances the mechanical strength and electrical stability of the connection.

[0010] Preferably, one side of the conductor is provided with a spring, and one side of the spring is fixedly connected to the inner wall of the mounting groove. The second conductor is designed to be elastic. The design of the spring and the elastic conductor ensures that the first conductor is always in close contact with the body, ensuring low contact resistance and avoiding the generation of electric arc.

[0011] Preferably, an indicator light is provided on one side of the outer wall of the voltage selector, and a main line is provided at the lower end of the indicator light. The indicator light can intuitively display the voltage selection status, which is convenient for user operation and fault diagnosis. The main line is located in the lower position to reduce internal circuit interference and optimize electrical safety.

[0012] Preferably, the inner wall of the mounting groove is provided with a threaded groove, and the outer wall of the lower end of the body is provided with a threaded wire. The cooperation between the threaded groove and the threaded wire makes the body installation more secure, prevents loosening and falling off, and at the same time maintains the convenience of disassembly, taking into account both stability and maintenance efficiency.

[0013] Preferably, the lower end of the housing is provided with a base plate, and the base plate is provided with positioning holes at the four corners. The design of the base plate and positioning holes facilitates the fixed installation of the equipment, enhances the overall stability, is suitable for various industrial environments, and reduces the performance impact caused by vibration or displacement.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model achieves multi-level voltage regulation through a voltage selector to adapt to different current requirements, thereby improving the applicability and safety of the equipment. The main body adopts a rotating installation design, combined with the elastic contact of conductor one and conductor two, to ensure stable conductivity while facilitating disassembly and maintenance, thus reducing maintenance costs and time.

[0016] II. Based on the first beneficial effect, this technical solution achieves the core advantages of multi-level voltage protection, rapid maintenance, and stable connection through the design of voltage selectors, modular body installation, and flexible conductive structures. Each claim further optimizes the reliability, safety, and ease of use of the equipment, such as details like relay fixing, joint reinforcement, threaded locking, and base plate positioning, enabling the device to operate efficiently even under complex working conditions. The overall structure is compact and functionally complete, combining practicality and economy, and is suitable for electrical systems requiring voltage regulation and high reliability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
