Description

Technical Field

[0001] The present invention belongs to the technical field of circuit breakers, and in particular relates to an Internet of Things molded case circuit breaker. Background Art

[0002] IoT molded case circuit breakers are usually equipped with intelligent protection modules, which can detect the current and voltage passing through the product in real time, and have protection functions such as overvoltage, undervoltage, phase loss, overload, and short circuit. Molded case circuit breakers can automatically cut off the current after the current exceeds the trip setting. Accidental detachment or poor contact between the circuit breaker and the wiring harness after docking may cause circuit interruption, thereby affecting the normal operation of the circuit.

[0003] In the prior art, when a circuit breaker is used, it is first installed on a frame, and after it is fixed, the wire harness to be connected is connected. The staff usually inserts the wire harness into the wiring hole of the circuit breaker, and then tightens the bolts to fix the insertion end of the wire harness. However, when multiple circuit breakers are installed and connected, the wire harness will be somewhat disordered on the frame, so that the staff may touch and pull the already connected wire harness during operation, and the wiring part will be bent at this time. If the wire harness is not inserted tightly or the bolts are not tightened, this will cause the connected wire harness to fall off or have poor contact, thereby affecting the efficiency of circuit breaker installation.

[0004] Therefore, there is a need for an IoT molded case circuit breaker to solve the problem in the prior art that the circuit breaker falls off or has poor contact with the wiring harness after being connected due to bending. Summary of the invention

[0041] There are two turning handles 86 , which are respectively fixedly sleeved on the ends of the rotating shaft 81 . Limiting components 87 that match the first gear 82 are provided on both sides of the circuit breaker body 1 .

[0042] It is worth noting that the turning handle 86 facilitates the rotation of the rotating shaft 81 , thus facilitating the movement of the holder 3 .

[0043] Further as Figure 1 , Figure 4 and Figure 5 As shown, it is worth to explain in detail that the anti-bending mechanism 9 includes:

[0044] A T-shaped slide groove 901 is provided on the surface of the fixing seat 6, and a W-shaped push rod 902 is slidably connected to the inner wall of the T-shaped slide groove 901. A plurality of arc-shaped clamping plates 903 matching with the wiring harness 2 are fixed on one side of two W-shaped push rods 902 close to each other at the same height;

[0045] U-shaped rack plates 904, four U-shaped rack plates 904 are provided and are respectively fixed to one side of the W-shaped push rod 902, four fixing blocks 905 are fixed to the upper and lower surfaces of the circuit breaker body 1, sleeves 906 are fixed to the ends of the two fixing blocks 905 on one side, and a transmission shaft 907 is rotatably connected inside the two sleeves 906 on one side, an incomplete gear 908 matching the U-shaped rack plate 904 is fixedly sleeved in the middle of the outer surface of the transmission shaft 907, a second gear 909 is fixed to both ends of the transmission shaft 907, and L-shaped racks 910 matching the second gear 909 are fixed to both sides of the rack rod 85.

[0046] It is worth noting that the incomplete gear 908 meshes with one side of the U-shaped rack plate 904, and the end of the W-shaped push rod 902 is T-shaped, thereby matching the T-shaped slide groove 901 to improve the stability of the W-shaped push rod 902 when sliding.

[0047] Embodiment 2:

[0048] Based on the first embodiment, Figure 2 and Figure 6 As shown, it is worth specifically explaining that the limit assembly 87 includes a U-shaped connecting block 871 fixed to the side of the circuit breaker body 1, a rectangular rod 872 is fixed on the inner side of the U-shaped connecting block 871, an L-shaped sliding rod 873 is slidably sleeved on the outer surface of the rectangular rod 872, and a latch tooth 874 is fixed on the end of the L-shaped sliding rod 873, which meshes with the first gear 82.

[0049] It is worth noting that after the wiring harness 2 is docked, the L-shaped slide bar 873 is pulled to slide on the rectangular rod 872 so that the latching tooth 874 engages with the first gear 82, thereby limiting the first gear 82 and maintaining the stability of the wiring harness 2 after docking.

[0050] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that a limit rod 10 is fixed to the inner wall of the T-shaped slide groove 901, and the limit rod 10 movably passes through the end of the W-shaped push rod 902. The inner diameter of the two arc-shaped clamping plates 903 on one side is larger than the diameter of the wiring harness 2, and the two L-shaped racks 910 on one side are U-shaped.

[0051] It is worth noting that the end of the W-shaped push rod 902 is limited by the limit rod 10 to improve the stability of the W-shaped push rod 902 when sliding in the T-shaped slide groove 901; the two arc-shaped clamping plates 903 are merged, and then the wiring harness 2 is wrapped in the two arc-shaped clamping plates 903, so as to limit the wiring harness 2 and prevent the wiring harness 2 from bending after being connected to the wiring terminal of the circuit breaker body 1.

[0052] This scheme has the following working process: first, multiple wire harnesses 2 are inserted into the threading hole 4 of the card holder 3. During the process of inserting the wire harness 2, the wire harness 2 drives the fixing sleeve 5 to enter the threading hole 4. After entering the threading hole 4, the fixing sleeve 5 squeezes the clamping strip 74, so that the clamping strip 74 moves into the installation slot 72 and compresses the telescopic rod 73 and the spring 75. Then, the wire harness 2 is rotated to drive the fixing sleeve 5 to rotate in the threading hole 4. When the clamping slot 71 on the fixing sleeve 5 rotates to one side of the installation slot 72, the clamping strip 74 is clamped in the clamping slot 71 under the elastic force of the spring 75, thereby limiting the wire harness 2.

[0053] Then, the turning handle 86 is rotated to drive the first gear 82 on the rotating shaft 81 to rotate, thereby driving the two rack rods 85 to move closer to each other, wherein the rack rod 85 drives the T-shaped slider 84 to slide in the guide rail 83 when moving, thereby limiting the rack rod 85 and improving the stability of the movement of the rack rod 85. When the rack rod 85 moves, it pulls the holder 3 at the wiring hole of the circuit breaker body 1 and moves toward the wiring hole, thereby driving the end of the wiring harness 2 to insert into the wiring hole of the circuit breaker body 1, and then the staff tightens the bolt to squeeze and fix the wiring harness 2 inserted into the wiring hole; when the rack rod 85 moves, It drives the L-shaped rack 910 to move, thereby driving the second gear 909 to rotate, and then drives the transmission shaft 907 to rotate in the sleeve 906, thereby driving the incomplete gear 908 to rotate, and then drives the two U-shaped rack plates 904 on one side to move closer to each other, so that the W-shaped push rod 902 approaches the wiring harness 2, and then the arc-shaped clamping plates 903 approach each other and limit the wiring harness 2, and then pull the L-shaped slide bar 873 to slide on the rectangular rod 872, so that the locking tooth 874 engages with the first gear 82, thereby limiting the first gear 82 and maintaining the stability of the wiring harness 2 after docking.

[0054] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art.
