Description

Technical Field

[0001] This utility model relates to the field of controller technology, specifically to a reactive power compensation controller. Background Technology

[0002] Reactive power compensation controllers are key devices in power systems used to regulate reactive power and improve the power factor of the power grid. Their structural stability and wiring reliability directly affect their operational performance. Existing reactive power compensation controllers typically integrate the wiring structure with the base shell, or use complex fasteners to fix the wiring components to the shell.

[0003] When the wiring structure suffers from wear, poor contact, or other faults, the controller needs to be completely disassembled or even the housing replaced, resulting in high maintenance costs and complicated operations. At the same time, the connection between traditional wiring components and the circuit board often relies on welding or multiple sets of bolts for fixing, which results in low positioning accuracy during assembly and is prone to loose wiring, affecting the stability of the controller's operation.

[0004] Therefore, there is an urgent need for a reactive power compensation controller structure with detachable wiring, convenient assembly, and reliable connection to solve the problems of inconvenient maintenance, low assembly efficiency, and insufficient connection stability of existing products. Utility Model Content

[0005] To address the shortcomings in the prior art, this utility model provides a reactive power compensation controller.

[0006] The technical solution adopted by this utility model is: a reactive power compensation controller, including a bottom shell, a cover, a display panel and circuit boards spaced apart on the display panel, and a wiring frame connected to the circuit board; The bottom of the base shell is provided with a long slot that is adapted to the wiring frame; The wiring frame is provided with several wiring grooves at intervals on the outer side of the bottom shell. The two ends of the wiring frame extend into the inner side of the bottom shell with clamping strips. The wiring grooves are provided with wiring terminals and fastening bolts. The side walls of the clamping strips and the inner bottom wall of the wiring frame are provided with fitting grooves that fit into the circuit board. The outer wall of the clamping strip is provided with a positioning protrusion, the upper end face of which abuts against the inner wall of the bottom shell. Both ends of the wiring frame are provided with outwardly protruding spring pieces, which abut against the outer wall of the bottom shell.

[0007] Furthermore, a guide slope is provided on one side of the spring sheet.

[0008] Furthermore, the wiring slots are separated by arc-blocking plates.

[0009] Furthermore, the height of the arc-blocking plate is 0.5-1cm.

[0010] Furthermore, a guide groove is provided on the inner wall of the bottom shell, and the positioning protrusion slides in conjunction with the guide groove.

[0011] Furthermore, raised protrusions are provided at the four corners of the bottom shell.

[0012] The beneficial effects of this utility model are: 1. Improved maintenance convenience: The wiring frame and the bottom shell are detachable. When the wiring structure such as the wiring slot and spring contacts are worn or malfunction, the wiring frame can be replaced separately, which greatly reduces maintenance costs and operation difficulty.

[0013] 2. Optimized assembly efficiency: After the wiring frame passes through the long slot from the inside of the bottom shell, the bottom shell can be directly clamped between the upper end face of the positioning protrusion and the spring piece. The elastic clamping of the positioning protrusion and the spring piece achieves quick positioning and fixation, eliminating the assembly steps of multiple sets of fasteners in the traditional method and improving assembly efficiency.

[0014] 3. Connection stability assurance: The wiring frame is fitted with the circuit board through the clamping strip and the fitting groove on the inner bottom wall. The positioning protrusion supports and positions the clamping strip, ensuring that the connection between the wiring frame and the circuit board is accurate and firm. At the same time, the wiring groove, together with the wiring terminal and bolt connection, further enhances the wiring stability and avoids poor contact problems caused by loosening.

[0015] 4. Outstanding structural design: The outward-curving structure of the spring piece and the upper end face of the positioning protrusion form a two-way elastic clamping and fixing, which not only ensures the reliability of the connection between the wiring frame and the bottom shell, but also provides elasticity for disassembly and assembly, taking into account both the fixing effect and the ease of operation.

[0016] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

The bottom of the base shell is provided with a long slot 6 that is adapted to the wiring frame; The wiring frame 5 is provided with several wiring grooves 7 at intervals on the outer side of the bottom shell. The two ends of the wiring frame 5 extend into the inner side of the bottom shell with clamping strips 8. The wiring grooves are provided with wiring terminals 16 and fastening bolts 17. The side walls of the clamping strips and the inner bottom wall of the wiring frame are provided with fitting grooves 9 that fit with the circuit board. The outer wall of the clamping strip is provided with a positioning protrusion 10, the upper end face of the positioning protrusion 10 abuts against the inner wall of the bottom shell, and the two ends of the wiring frame are provided with outwardly protruding spring pieces 11, which abut against the outer wall of the bottom shell.

[0028] In the above technical solution, an independent wiring frame is added, and the bottom of the base shell is provided with an adaptable long slot as a wiring frame installation channel; the outside of the wiring frame is provided with a wiring groove for wiring, and the clamping strips extending inward at both ends and the inner bottom wall are provided with fitting grooves to achieve fitting and positioning with the circuit board; the positioning protrusions on the outer wall of the clamping strips abut against the inner wall of the base shell, and the outwardly protruding spring pieces at both ends of the wiring frame abut against the outer wall of the base shell.

[0029] The detachable design allows for individual replacement of the wiring frame in case of failure, without the need to disassemble the entire frame or replace the bottom shell, reducing maintenance costs and difficulty; the fitting groove and positioning protrusion ensure a precise and secure connection between the wiring frame and the circuit board, and the wiring groove is equipped with terminal bolts to improve connection reliability.

[0030] Specifically, a guide slope 12 is provided on one side of the spring sheet.

[0031] In this embodiment, a guide slope is provided on one side of the spring piece.
