[0002] In the power distribution system, molded case switches (MCCs) serve as crucial protection and control devices, undertaking the key functions of connecting and disconnecting circuits, as well as providing overload and short-circuit protection. Their performance directly affects the safe and stable operation of the power distribution system. Due to their compact structure, small size, high breaking capacity, and convenient installation, MCCs are widely used in low-voltage power distribution systems in various fields, including industrial, commercial, and civil buildings.

[0003] In the current technology of power distribution control equipment, molded case switches are usually fixedly installed inside power distribution control equipment such as distribution boxes to ensure the normal operation of the power distribution control equipment and maintain the stability of the power distribution lines.

[0004] However, existing molded case switches in power distribution control equipment cannot provide limit protection for the lines connected to the switch terminals. As a result, the lines connected to the switch terminals are prone to loosening or falling off during long-term use, which affects the normal operation of the power distribution control equipment, poses a significant safety hazard, and fails to meet actual usage requirements.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a molded case switch for power distribution control equipment, including a main body mechanism 1.

[0031] Module mounting mechanism 2 is located on one side of the main body mechanism 1;

[0032] The quick-release mechanism 3 is located on one side of the main body mechanism 1 and is compatible with the module installation mechanism 2;

[0033] Two cable anti-detachment protection mechanisms 4 are respectively installed at the top and bottom of the main body 1;

[0034] Two locking mechanisms 5 are respectively installed on the outside of a corresponding cable anti-detachment protection mechanism 4;

[0035] Two heat dissipation mechanisms 6 are respectively located on both sides of the main body mechanism 1;

[0036] The cable anti-detachment protection mechanism 4 includes a rotating shaft 401, which is rotatably mounted on one end of the main body mechanism 1. A limit end cover 402 is installed on one end of the rotating shaft 401, and an operating handwheel 403 is connected to the other end of the rotating shaft 401. Multiple sets of second L-shaped frames 404 are installed on the outside of the rotating shaft 401. An insulating protective cover 405 is connected to one end of each set of second L-shaped frames 404. A connecting frame 406 is connected between every two adjacent insulating protective covers 405. By setting up the cable anti-detachment protection mechanism 4, the line connected to the terminal of the molded case switch can be protected, and the line can be pressed and fixed, effectively preventing the line from loosening or falling off, ensuring the normal operation of the power distribution control equipment, avoiding safety hazards, and meeting the actual use requirements.

[0037] like Figure 2 and Figure 3 As shown, the quick-installation mechanism 3 includes two fixed frames 301, both of which are installed on one side of the main body 1. Two fixed rods 302 are fixedly installed between the two fixed frames 301. Springs 303 are sleeved on the outer sides of both ends of each fixed rod 302. Two sliding frames 304 are slidably installed on the outer sides of the two fixed rods 302. A pull ring 305 is installed on one side of each sliding frame 304. With the quick-installation mechanism 3, clamping installation can replace the traditional bolt fixing installation method, which facilitates the installation and disassembly of the molded case switch, effectively reduces the difficulty of operation, and saves the later maintenance cost.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the main body 1 includes a switch body 101. A high-performance plastic housing 102 is fixedly installed on one side of the switch body 101 by bolts. By setting the main body 1, the overall sealing of the plastic housing switch can be guaranteed, while its insulation performance can be improved, reducing the probability of safety accidents such as leakage or short circuit.

[0039] like Figure 1 and Figure 2 As shown, the modular installation mechanism 2 includes an installation template 201, which is set on one side of the switch body 101. Two first L-shaped brackets 202 are symmetrically installed on one side of the installation template 201. Installation bolts 203 are installed at the four corners of one side of the installation template 201. A washer 204 is fitted on the outside of each installation bolt 203. By setting up the modular installation mechanism 2, the difficulty of installing and disassembling the molded case switch as a whole can be reduced by adopting a modular installation method, which facilitates subsequent inspection and maintenance.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the locking mechanism 5 includes a fixed frame 501, which is fixedly installed on one side of the high-performance plastic housing 102. A fixed clamping block 502 is installed on the inner side of the fixed frame 501. Two guide rods 503 are installed at one end of the fixed clamping block 502. A movable clamping block 504 is slidably installed on the outer side of the two guide rods 503. A connecting bolt 505 is installed at one end of the fixed frame 501. One end of the connecting bolt 505 is rotatably connected to the movable clamping block 504. By setting the locking mechanism 5, the cable anti-detachment protection mechanism 4 can be locked, effectively preventing it from spinning and loosening, thereby improving safety and stability.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the heat dissipation mechanism 6 includes a heat dissipation port 601, which is opened through both sides of the switch body 101 and the high-performance plastic housing 102. Heat dissipation fins 602 are provided on the inner side of the heat dissipation port 601, and a heat conduction plate 603 is installed at one end of the heat dissipation fins 602. By setting up the heat dissipation mechanism 6, the heat dissipation performance of the plastic housing switch can be effectively improved, preventing heat accumulation from damaging the internal structure of the plastic housing switch, thereby extending its service life.

[0042] The usage method and working principle of this device are as follows: First, tighten the mounting bolts 203 to install the mounting template 201 inside the power distribution control equipment. Next, pull the two pull rings 305 to make the sliding frame 304 slide on the fixed rod 302 and compress the spring 303 to retract it. Then, place one side of the switch body 101 against the surface of the two first L-shaped frames 202 and release the pull rings 305 to make the spring 303 rebound and push the sliding frame 304 to slide on the fixed rod 302, so that it engages with the first L-shaped frame 202. Then, connect the required circuit to the terminal of the molded case switch. Then, tighten the operating handwheel 403 to make the rotating shaft 401 drive the second L-shaped frame 404 and the insulating protective cover 405 to rotate, protect the line connected to the terminal of the molded case switch and press it to fix it. Finally, tighten the connecting bolts 505 to push the movable clamp 504 to slide on the guide rod 503, and then cooperate with the fixed clamp 502 to clamp and lock the rotating shaft 401 to prevent it from spinning.

[0043] By following the steps outlined above, you can complete the use of the molded case switch in the power distribution control equipment.
