A wire anti-loosening type intelligent circuit breaker

Abstract

The present application discloses a wire anti-loosening intelligent circuit breaker, which relates to the technical field of electrical switch devices. It includes a circuit breaker body, a fixing component, a clamping component, an intercepting component, and a locking component. The fixing component is used to connect the circuit breaker body circuit. There are two fixing components, which are symmetrically arranged at the upper and lower ends of the circuit breaker body. The fixing component includes a fixing shell, a first through port, a second through port, and a wire. The number of the first through ports is the same as that of the second through ports and they correspond one by one. The fixing shell is fixed on the circuit breaker body. It can be realized that by adding an electromagnet and a first iron sheet, the position of the locking part can be adjusted to avoid the situation that when the wire extends to the lowest end of the first through port and contacts the conductive part, the locking part is not fully rotated, resulting in the limiting rod being unable to be inserted into the limiting groove, and the positions of the locking part and the wire are restricted. At the same time, torsion springs are added at both ends where the locking part is rotatably connected, and the initial position of the locking part is restricted by the torsion springs.

Description

Technical Field

[0001] The present invention relates to the technical field of electrical switch devices, and in particular to an intelligent circuit breaker with anti-loosening wires. Background Art

[0002] A circuit breaker refers to a switch device that can close, carry, and interrupt the current under normal or abnormal circuit conditions; a circuit breaker is an important electrical device for the protection and operation of a power system, which can be used to distribute electric energy, start an asynchronous motor infrequently, and protect the power supply line and the motor, etc.

[0003] Currently, when installing a circuit breaker, the connection between the wire and the circuit breaker is unstable, and it is easy to shift when pulling the wire, resulting in poor contact.

[0004] For example, the circuit breaker provided in the authorized publication number CN114597103B wires by first sleeving the limiting ring of the auxiliary plug on the wiring end of the wire and then wiring. When the wire descends, it presses the first section, causing the locking member to rotate as a whole. During the rotation, the second section is stuck above the limiting ring. When pressed to the lowest end, the locking rod will extend into the card slot to limit the position of the wire; the wiring end of the wire can be closely matched with the locking component of the circuit breaker under the action of the limiting ring of the auxiliary plug, and the wiring end of the wire will not be squeezed open and displaced under the pulling force of an external force, resulting in loose wiring, thereby avoiding burning out the circuit breaker and the wire.

[0005] It has great drawbacks: when the wire touches the lowest end of the second opening, the locking member loses the rotation power. At this time, the wire does not touch the locking member and has not reached the final state. The wire is intercepted by the second section and cannot continue to touch the first section. The second section has not touched the auxiliary plug or the wire, and the locking rod has not been inserted into the card slot, resulting in the device not locking the wire and reducing the locking effect on the wire; at the same time, the locking member is rotatably connected in the second opening without other limiting structures. The locking member is composed of a first section and a second section, and their sizes are inconsistent, resulting in the heavier one being at the lower part. When the wire descends, it cannot touch the first section. Summary of the Invention

[0006] In the embodiment of the present application, by providing a wire anti-loosening intelligent circuit breaker, the problem in the prior art is solved that when the wire touches the lowermost end of the second opening, the locking member loses the rotational power. At this time, the wire does not touch the locking member and does not reach the final state. The wire is intercepted by the second section and cannot continue to touch the first section. The second section has not touched the auxiliary plug or the wire, and the locking rod has not been inserted into the card slot, resulting in the device not locking the wire, and the locking effect on the wire is reduced. At the same time, the locking member is rotatably connected in the second opening and has no other limiting structure. The locking member is composed of a first section and a second section, and their sizes are inconsistent, resulting in the heavier one being at the lower part. When the wire descends, it cannot touch the first section. By adding an electromagnet and an iron sheet 1, the position of the locking member can be adjusted, avoiding the situation that when the wire extends to the lowermost end of the through hole 1 and touches the conductive member, the locking member has not rotated completely, resulting in the limiting rod not being able to be inserted into the limiting slot, and restricting the positions of the locking member and the wire. At the same time, torsion springs are added at both ends where the locking member is rotatably connected to limit the initial position of the locking member to avoid the overall rotation of the device causing the device to not work properly.

When the locking member 410 rotates 90 degrees, the limiting rod 330 is inserted into the limiting groove 412, the lower end of the wire 220 abuts against the conductive member 230, and the first groove 411 of the locking member 410 abuts against the upper part of the fixed ring 510 and the wire 220;

[0129] The length of the fixed ring 510 in the axial direction is the same as the distance from the axis of the locking member 410 to the side wall of the circuit breaker body 100 close to the second through port 212.

[0130] When the lead 220 is in the lock, the guide 520 is tightened and the fixing ring 510 is pressed against the guide 520, so that the distance between the guide 520 and the fixing ring 510 and the lead 220 is reduced. Then, the guide 520 is screwed into the limit opening 511 through the abutment bolt 530, so that one end of the abutment bolt 530 abuts against the guide 520, and the lead 220 is fixed tightly. Then, the guide 220 is inserted into the through-port 1 211. During this process, the deformable piece 520 is close to the side of the through-port 1 211 away from the locking piece 410, and the fixing ring 510 is toward the side close to the locking piece 410. When the guide 520 is continuously inserted inward, the guide 220 and the fixing ring 510 abut against the groove 1 411 of the locking piece 410, so that the lock is tightened. When the wire 220 is to be removed, the pull plate 340 is manually pulled to disengage the limit rod 330 from the limit groove 412, thereby removing the restriction on the position of the locking member 410. When the wire 220 is to be removed from the opening 211, the locking member 410 is reset by rotating the torsion spring at the connection. When the power supply battery 250 is used for a long time and the power becomes weak, the power supply battery 250 can be removed and replaced.

[0131] Compared with the prior art, by adding an electromagnet 240 and an iron sheet 440, the position of the locking member 410 can be adjusted to prevent the locking member 410 from not fully rotating when the wire 220 extends into the lowest end of the through-port 211 and contacts the conductive member 230, resulting in the limit rod 330 being unable to be inserted into the limit groove 412, thereby limiting the position of the locking member 410 and the wire 220; at the same time, torsion springs are added to both ends of the rotating connection of the locking member 410, and the initial position of the locking member 410 is limited by the torsion springs to prevent the entire device from being unable to be used normally due to the rotation of the entire device.

[0132] Example 2: When using Example 1, the position of the wire 220 is fixed by the rotating locking member 410 and the groove 411 on the locking member 410, but the fixing effect is poor. Based on this, the solution of Example 1 is improved, such as Figures 8-10 As shown:

[0133] The interception assembly 400 further includes a second groove 413 and a second iron sheet 450;

[0134] When the torsion spring on the rotating rod of the locking member 410 is in an unloaded state, on one side surface of the first groove 411 perpendicular to the telescopic direction of the limiting rod 330, there is a second groove 413, and the first iron sheet 440 is fixed on the side of the second groove 413 away from its opening.

[0135] The second iron sheet 450 is arranged on the side of the first iron sheet 440 close to the opening of the second groove 413, and the first iron sheet 440 and the second iron sheet 450 are connected by rubber.

[0136] When the first groove 411 of the locking member 410 abuts against the fixed ring 510, the second iron sheet 450 also abuts against the fixed ring 510.

[0137] When the lower end of the wire 220 abuts against the conductive member 230, the electromagnet 240 is powered on and activated, and can adsorb the first iron sheet 440 and the second iron sheet 450. The first groove 411 and the second iron sheet 450 together abut against the fixed ring 510. At this time, the limiting rod 330 has been inserted into the limiting groove 412 to limit the position of the locking member 410; then the electromagnet 240 is not powered off and continuously adsorbs the first iron sheet 440 and the second iron sheet 450. Since the second iron sheet 450 and the first iron sheet 440 are connected by rubber, the second iron sheet 450 can be pulled for a certain distance and continuously extends downward to abut against the fixed ring 510.

[0138] By increasing the second iron sheet 450 and connecting the second iron sheet 450 and the first iron sheet 440 with rubber, under the continuous adsorption of the electromagnet 240, it can be pulled for a certain distance and continuously extends downward to abut against the fixed ring 510, thereby improving the fixing effect on the wire 220.

[0139] Embodiment 3: When Embodiment 2 is in use, since it is manually installed, during the process of the wire 220 extending in, the wire 220 will tilt. At the same time, the wire 220 has a lower hardness. When the lower end abuts against the conductive member 230, it will be pressed downward for a certain distance, resulting in tilting. The tilted wire 220 may not be fixed evenly and tightly by the locking member 410, affecting the reliability of the connection; at the same time, the actual contact area between the tilted wire 220 and the conductive member 230 is reduced, which will affect the current conduction efficiency, increase the contact resistance, and thus generate more heat. Long-term operation may lead to overheating problems. Therefore, the solution of Embodiment 2 is improved as follows Figures 11-15 as shown:

[0140] The fixing assembly 200 further includes a first air duct 213;

[0141] The number of the first air ducts 213 is the same as the number of the intercepting assemblies 400 and they correspond one by one;

[0142] The fixed housing 210 is provided with an air duct 213. One end of the air duct 213 communicates with the second through port 212, and the end of the air duct 213 away from the second through port 212 penetrates through the fixed housing 210;

[0143] The end of the air duct 213 away from the second through port 212 communicates with the inflation mechanism;

[0144] It further includes an adjustment assembly 600, and the adjustment assembly 600 includes a swing plate 610, a connecting plate 620, an airbag 630 and an air duct 640;

[0145] When the torsion spring on the rotating rod of the locking member 410 is in a non-loaded state, the connecting plate 620 is fixed on the side of the first groove 411 parallel to the telescopic direction of the limiting rod 330, and the connecting plate 620 is made of rubber;

[0146] There are two swing plates 610 and two airbags 630 respectively, and they correspond to the two ends of the connecting plate 620 respectively;

[0147] The swing plates 610 are fixed at both ends of the connecting plate 620, the airbags 630 are fixed between the swing plates 610 and the first groove 411, and the airbags 630 are fixed on the side of the first groove 411 parallel to the telescopic direction of the limiting rod 330, and the two airbags 630 communicate with each other;

[0148] One end of the air duct 640 is fixed to the end of the air duct 213 located in the second through port 212;

[0149] The interception assembly 400 further includes an air duct 414;

[0150] The locking member 410 is provided with an air duct 414. One end of the air duct 414 communicates with the airbag 630, and the end of the air duct 640 away from the air duct 213 is fixed to the end of the air duct 414 away from the airbag 630;

[0151] The air duct 640 is a telescopic hose;

[0152] The inflation mechanism is prior art and will not be elaborated here.

[0153] When the wire 220 extends from the first through-port 211 and touches the locking member 410, the inflation mechanism is activated. The inflation mechanism continuously inflates and deflates the airbag 630, causing the swing plate 610 to continuously swing, touch the wire 220, and fan to adjust the position of the wire 220. After the limiting rod 330 is inserted into the limiting groove 412 to limit the position of the locking member 410, the airbag 630 is continuously inflated, so that the airbag 630 and the swing plate 610 clamp the wire 220; at the same time, when the device is used for a long time and the connection of the wire 220 generates heat, the airbag 630 can be inflated and deflated, causing the swing plate 610 to continuously swing, fan the internal air, cool the wire 220, and at the same time fan off the attached dust.

[0154] Through the inflation and deflation of the airbag 630, the swing plate 610 swings, touches the wire 220, and continuously adjusts the position of the wire 220, which can adjust the position of the wire 220 and prevent the wire 220 from tilting; at the same time, through the expansion of the airbag 630, the wire 220 can be clamped to improve the fixing effect on the wire 220; when the device is used for a long time, the inflation and deflation of the airbag 630 cause the swing plate 610 to continuously swing, fan the internal air, which can cool the wire 220, improve its service life, and at the same time fan off the attached dust, improving the conductivity and heat dissipation effect of the wire 220.

[0155] Embodiment 4: When Embodiment 3 is in use, through the expansion of the airbag 630, the clamping effect on the wire 220 is improved, but the device can still be improved to further improve the clamping and fixing effect on the wire 220. Based on this, the solution of Embodiment 3 is improved as follows Figures 16-17 shown:

[0156] The fixing assembly 200 further includes a sliding group;

[0157] The number of the sliding groups is the same as that of the interception assemblies 400 and they are in one-to-one correspondence. The sliding group includes two sliding grooves 214:

[0158] The two sliding grooves 214 are symmetrically arranged in the second through-port 212, and the slider 420 is slidably arranged in the sliding groove 214;

[0159] The length direction of the sliding groove 214 is parallel to the telescopic direction of the limiting rod 330, and the length direction of the sliding groove 214 is the sliding direction of the slider 420;

[0160] The interception assembly 400 further includes a reset rope 430;

[0161] There are two reset ropes 430, which correspond to the two sliders 420 one by one. The reset rope 430 is fixed on one side of the slider 420, and the end of the reset rope 430 away from the slider 420 is fixed on the side of the sliding groove 214 close to the clamping component 300;

[0162] The reset rope 430 is an elastic rope.

[0163] Before inserting the wire 220 into the first through hole 211, the operator first pulls the pull plate 340 to make the limiting rod 330 not contact the locking part 410, and the locking part 410 is reset by the reset rope 430; insert the wire 220 into the first through hole 211 and keep inserting it inward until it contacts the first groove 411 of the locking part 410, causing the locking part 410 to rotate. When the lower end of the wire 220 contacts the conductive part 230, the electromagnet 240 is powered on and starts to adsorb the first iron sheet 440, causing the incompletely rotated locking part 410 to rotate again. The locking part 410 contacts the fixed ring 510 and the wire 220 through the first groove 411, and the second iron sheet 450 contacts the fixed ring 510 to limit the position of the wire 220. At this time, the operator releases the pull plate 340, and the limiting rod 330 extends into the limiting groove 412 by the elastic force of the spring 320 and contacts the locking part 410 to move it towards the side close to the wire 220, causing the locking part 410 to continuously press the wire 220; when the wire 220 needs to be disassembled, the operator pulls the pull plate 340 to make the limiting rod 330 disengage from the limiting groove 412, canceling the limitation on the position of the locking part 410. At the same time, the locking part 410 is reset by the elastic force of the reset rope 430 for convenient use next time. When the operator pulls the wire 220 out of the first through hole 211, the locking part 410 rotates and resets through the torsion spring at the rotating connection.

[0164] The locking part 410 is slidably connected. After the wire 220 is fixed and limited, the locking part 410 can move towards the side of the wire 220 by the elastic force of the spring 320 and continuously press the wire 220, thereby further improving the fixing effect on the wire 220.

[0165] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
