[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment of this utility model, such as Figure 1-6As shown, a locking device for facilitating the assembly and disassembly of electrical components is provided, including a circuit board 10, an electrical component body, and a locking assembly. The electrical component body includes a housing 20. A connecting platform 21, which is fixed to the circuit board 10, is provided on the housing 20, and a conductive element 22 is provided inside the connecting platform 21. The locking assembly includes a fixing member and a connecting post 40. The fixing member is located between the connecting platform 21 and the conductive element 22. The connecting post 40 is located on the circuit board 10, and the connecting post 40 is detachably connected to the fixing member. The connecting post 40 is connected to a wire, allowing the wire to be stably connected to the circuit board 10, avoiding the previous problem of poor connection between the connecting platform 21 and the wire, and improving the operational stability of the electrical system.

[0036] In this embodiment, the electrical component body can be a variety of electrical components such as disconnect switches, circuit breakers, residual current devices, phase sequence protectors, over / under voltage protectors, surge protectors, fuses, contactors, thermal relays, filters, and switching power supplies. The specific electrical component to be selected can be chosen according to actual production needs. By setting connection platforms 21 at both ends of the housing 20 of these electrical components, and by using locking components to achieve a detachable connection between the connection platforms 21 and the circuit board 10, the electrical components can be easily installed and removed from the circuit board, greatly shortening the installation and replacement time.

[0037] By setting up a locking assembly and detachably connecting the connecting post 40 to the fixing member, regardless of whether the fixing member is a locking member 31a or a swivel cap 31b, it can be quickly fixed to the connecting post 40, thus quickly completing the locking and fixing of electrical components, greatly simplifying the installation process and saving installation time. At the same time, through the detachable connection between the connecting post 40 and the fixing member, electrical components can also be easily removed from the circuit board 10 without disconnecting the wires, greatly shortening maintenance and replacement time.

[0038] Preferably, such as Figure 1-2 As shown, in the first configuration of the fixing component, specifically, the fixing component is a locking component 31a, which is a locking screw. The locking component 31a is located on the conductive component 22 and is movably connected to the conductive component 22. The connecting post 40 has a first connecting hole 41a corresponding to the locking component 31a. When the electrical component body is installed on the circuit board 10, the bottom end of the locking component 31a passes through the conductive component 22 and is threadedly connected to the first connecting hole 41a, thereby locking the locking component 31a into the connecting post 40. By setting the locking component 31a and threading it to the first connecting hole 41a in the connecting post 40, the electrical component can be fixed to the circuit board 10. This not only ensures fast installation but also reliable locking, guaranteeing a stable and good electrical connection between the electrical component and the circuit board 10, and improving the reliability of the electrical system operation.

[0039] Preferably, such as Figure 3-5As shown, in the second configuration of the fastener, the fastener is a swivel cap 31b, which is fixed between the conductive component 22 and the connecting platform 21. The connecting post 40 has an outwardly extending connecting portion 41b, and the swivel cap 31b can engage or disengage from the connecting portion 41b. By providing the swivel cap 31b, and by engaging with the connecting portion 41b in the connecting post 40, a locking mechanism is achieved between the swivel cap 31b and the connecting post 40. This makes the installation and disassembly of electrical components more convenient, significantly shortens installation and disassembly time, reduces the labor intensity of operators, and improves work efficiency.

[0040] Furthermore, the screw cap 31b has a hollow internal structure, and the end of the screw cap 31b near the connecting post 40 has an opening. The opening can engage or disengage from the connecting part 41b.

[0041] like Figure 5 As shown, in the first configuration of the swivel cap 31b, specifically, two sets of bosses 32b protruding towards the central axis of the swivel cap 31b are provided within the opening, and the two sets of bosses 32b are symmetrically distributed within the opening. The connecting part 41b has two sets of entry parts 42b corresponding to the bosses 32b, and a rotating groove 43b is provided between the connecting part 41b and the connecting post 40, allowing the bosses 32b to enter or disengage from the rotating groove 43b. By providing the bosses 32b, entry parts 42b, and rotating groove 43b, during installation, simply align the bosses 32b of the swivel cap 31b with the entry parts 42b of the connecting part 41b, and then rotate the swivel cap 31b to allow the bosses 32b to enter the rotating groove 43b to complete the engagement. During disassembly, simply rotate the swivel cap 31b in the opposite direction to disengage the bosses 32b from the rotating groove 43b. This operation is simple and convenient, avoiding the connection instability problems caused by loose or stripped screws in traditional installations, and improving the quality and stability of electrical component installation.

[0042] Furthermore, such as Figure 6 As shown, in the second configuration of the rotating cap 31b, specifically, an elastic limiting platform 31c protruding towards the central axis of the rotating cap 31b is provided inside the opening. The elastic limiting platform 31c has a ring structure and is made of an elastic material, such as rubber or silicone. The connecting part 41b is provided with an outwardly extending fixing part 42c, and a snap-fit ​​groove 43c is provided between the fixing part 42c and the connecting post 40. The elastic limiting platform 31c can enter or disengage from the snap-fit ​​groove 43c.

[0043] By using an elastic limiting platform 31c made of elastic material, during installation, the elastic limiting platform 31c is directly snapped into the fixing part 42c of the connecting column 40 and locked into the locking groove 43c, thus completing the fixing of the cap 31b and the connecting column 40. This makes the installation process more convenient and improves work efficiency and installation quality.

[0044] Furthermore, the conductive component 22 includes a conductive sheet 221 and a conductive post 222. One end of the conductive sheet 221 is fixed inside the connecting platform 21, and the other end extends into the housing 20. The conductive post 222 is disposed on the conductive sheet 221 and located inside the connecting platform 21. By setting the conductive sheet 221 and the conductive post 222, the conductive sheet 221 can effectively connect the internal circuit of the electrical component to the external circuit board 10, while the conductive post 222 further enhances the reliability and conductivity of the connection, ensuring good transmission of electrical signals, reducing electrical faults caused by poor contact, and improving the operational stability and safety of the electrical system.

[0045] Preferably, the circuit board 10 is provided with an insulating layer 11, which is located between the circuit board 10 and the electrical component body. By providing the insulating layer 11, the electrical connection between the circuit board 10 and the electrical component body is effectively isolated, preventing safety hazards such as leakage.

[0046] Furthermore, a protective shell 12 is provided between the circuit board 10 and the electrical component body, and the protective shell 12 is located above the insulation layer 11. By providing the protective shell 12, the insulation layer 11 is protected from damage by the external environment.

[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
