Technical Field
[0001] The utility model relates to the technical field of circuit breakers, and more specifically to a power circuit breaker with convenient connection. Background Art
[0002] At present, most power circuit breakers use the traditional method of bolting and fixing the connection between the power-on contact and the wiring. During the equipment installation stage, construction workers need to use tools such as wrenches to tighten the bolts one by one to ensure that the wiring is firm and prevent loosening from causing poor contact, heating, or even power outages. When it is necessary to remove the wires for equipment maintenance, upgrades, or troubleshooting, tools are also needed to spend a lot of time unscrewing the bolts and completing the removal operation. In some places with extremely high requirements for power supply continuity, such as the intensive care unit of a hospital and the core computer room of a data center, this time-consuming wiring and removal process seriously affects work efficiency. Long-term power outages may cause interruptions in the operation of medical equipment and endanger the lives of patients; data centers may lose data and shut down their businesses due to power outages, resulting in immeasurable economic losses. In view of this, we propose a power circuit breaker that is easy to connect. Utility Model Content

[0025] like Figures 1 to 7As shown, the utility model relates to an electric circuit breaker with convenient connection, including a circuit breaker body 1, one side of the circuit breaker body 1 is set as a wiring point, a power-on plate 2 embedded in the circuit breaker body 1 is arranged at the wiring point, one side of the power-on plate 2 is provided with an insulating plate 3, a wiring clamping structure 4 is provided between the power-on plate 2 and the insulating plate 3, the wiring clamping structure 4 includes a plurality of wiring clamping blocks 401, and a circular cavity for clamping the wiring is formed when the plurality of wiring clamping blocks 401 are fully closed and tightly attached, a wiring movable rod 402 made of non-conductive material is penetrated and movably connected at the end of the wiring clamping block 401, a plurality of wiring guide grooves 403 are provided on the power-on plate 2 and the insulating plate 3, and the wiring movable rod 402 slides within the wiring guide groove 403.
[0026] A wiring operation structure 5 for wiring by pressing is provided on one side of the isolation plate 3, and the wiring operation structure 5 includes an internally hollow wiring loose clamp sleeve 501, and the outer periphery of the wiring loose clamp sleeve 501 and the inside of the circuit breaker body 1 are limited sliding, and the limited sliding is achieved by a slide groove and a slider. The wiring loose clamp sleeve 501 is a structure with a gradually increasing diameter from small to large, and one end of the wiring movable rod 402 is an extended design. The internal increasing inclined surface of the wiring loose clamp sleeve 501 contacts the end of the wiring movable rod 402, and an outer ring sleeve 502 is connected to one side of the wiring loose clamp sleeve 501. The interior of the outer ring sleeve 502 is a hollow structure, and a socket is opened on the outer periphery of the outer ring sleeve 502. A movable pin 7 fixed to the socket is provided on the circuit breaker body 1, and the movable pin 7 can be an interference fit or can be fixed by a partial external thread.
[0027] Working principle: When it is necessary to connect the wiring, you only need to pass the copper wire part of the wiring through the outer ring sleeve 502 and the wiring loose clamp sleeve 501, and place it between multiple wiring clamp blocks 401. At this time, press the outer ring sleeve 502 to drive the wiring loose clamp sleeve 501 to move in a limited position, so that the arc surface of the inner wall of the wiring loose clamp sleeve 501 is synchronously in contact with multiple wiring movable rods 402, and during the pressing process, the wiring movable rods 402 can be synchronously displaced, further making the multiple wiring clamp blocks 401 completely closed and tightly attached, and then insert the movable pin 7 to fix the wiring.
[0028] In order to achieve automatic loosening when there is no more pressure, a plurality of spring shells 8 are installed near the wiring movable rod 402 on the isolation plate 3, and a tensioning spring 9 is connected between the spring shell 8 and the wiring movable rod 402. By pulling out the movable pin 7, the wiring movable rod 402 can be automatically pushed open by the elastic force of the tensioning spring 9, so that it can be automatically reset, the wire clamping can be cancelled, and the wire removal can be achieved.
[0029] By pressing and pulling, the wiring can be fixed and removed in two actions, which greatly improves the convenience and wiring efficiency.
[0030] In order to further improve the stability of the wiring, a wiring inverted clamp structure 6 is also arranged between the insulating plate 3. The wiring inverted clamp structure 6 is made of metal material. The wiring inverted clamp structure 6 includes a bent arc rod 601 that penetrates the wiring clamp block 401. A connecting plate 602 is installed at one end of the bent arc rod 601. A hinged rod 603 is hinged on the outer periphery of the connecting plate 602. The hinged rod 603 is located inside another adjacent wiring clamp block 401, and one end of the hinged rod 603 is hinged to the inside of the wiring clamp block 401.
[0031] The wiring clamp structure 6 also includes a wiring barb 64, which is provided with a barb-shaped structure and is inserted between the copper wires of the wiring. The wiring barb 64 includes a wiring semicircular rod 641. The arc center of the wiring semicircular rod 641 is the same as the curved arc rod 601. The cross-section of the wiring semicircular rod 641 is a semicircular structure. A plurality of inner cavities are opened on one side of the wiring semicircular rod 641, and movable barbs 642 are arranged in the inner cavity. A fixing ring 643 is fixed between one end of the movable barb 642 and the inner cavity.
[0032] Working principle: through the movement between multiple wiring clamp blocks 401, when multiple wiring clamp blocks 401 are separated, the curved rod 601 can be pulled to move and shrink into the groove. When the multiple wiring clamp blocks 401 are in close contact with each other, the curved rod 601 will be gradually pushed out. When the curved rod 601 is pushed out, it can drive the wiring semicircular rod 641 to be inserted into the copper wire in the outer area of the wiring. Due to the movable rotating design of the movable barb 642, the force during the insertion process will form a barb-shaped shape. When it is completely fixed, the extrusion of the wiring copper wire by multiple wiring clamp blocks 401, the insertion of the wiring semicircular rod 641 and the barb structure formed by the movable barb 642 further expand the contact surface, making the power supply more stable, and the extrusion between the three increases the friction and constraint force, further improving the connection stability.
[0033] It is worth mentioning that, since the movable barb 642 is movable and rotatable, it can also be rotated in the opposite direction when the stitches are removed, thereby canceling its hook shape and preventing the stitches from getting stuck.
[0034] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
