Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a circuit breaker that is easy to connect in series. Background Technology

[0002] A circuit breaker is an electrical device used to interrupt current in a circuit. It is typically used to prevent circuit overload or short circuit. It is an important safety device in power systems, protecting electrical equipment from damage and preventing dangers such as fires. The development of circuit breakers can be traced back to the late 19th century. Initially designed to protect electrical equipment and personnel, circuit breakers have evolved and improved with the development of electrical technology and have now become an indispensable part of modern power systems.

[0003] However, existing circuit breakers have the following problems:

[0004] When using existing circuit breakers, operators often slip their fingers, which can lead to operational errors. Furthermore, prolonged use of the circuit breaker switch may cause the switch to loosen, resulting in intermittent operation. Intermittent operation can lead to short circuits or even damage to the circuit breaker.

[0005] To address the aforementioned issues, this application proposes a circuit breaker that is easy to connect in series. Utility Model Content

[0006] This utility model aims to provide a circuit breaker that is easy to connect in series. It is mainly used to solve the problem that when using existing circuit breakers, operators often slip their fingers, which may lead to operational errors due to slippage. In addition, when operators use the circuit breaker switch for a long time, the switch part may become loose, resulting in intermittent operation of the circuit breaker. When the circuit breaker is operated intermittently, it may cause a short circuit, or even damage the circuit breaker.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A circuit breaker that is easy to connect in series includes a circuit breaker, a limiting shell installed at the top of the circuit breaker, a switch connected to the top of the circuit breaker and located inside the limiting shell, the switch including a rotating ring and a pull rod, the rotating ring being installed on the top of the circuit breaker, the pull rod being connected to the top of the rotating ring, main limiting holes being equally spaced on the outer side of the limiting shell, a rotating groove being provided inside the limiting shell, and a switch limiting hole adapted to the main limiting holes being provided at the front end of the pull rod.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When using this circuit breaker, because friction grooves are set at the top switch of the circuit breaker, the operator will not make mistakes due to slippage of the hand when pushing the switch. After working for a long time, the operator can insert the pin into the main limit hole on the outside of the limit housing and then into the switch limit hole on the pull rod to fix the switch and prevent the circuit breaker from being damaged due to loosening.

[0011] 2. Beneficial effects: By setting friction texture on the circuit breaker switch, the friction texture can prevent the operator's fingers from slipping when pushing the circuit breaker switch. In addition, limit holes are set on the outside of the limit housing and on the switch. The switch can be fixed by inserting the pin into the limit hole, which prevents the switch from loosening due to long-term use and indirectly causing damage to the circuit breaker.

[0012] Preferably, the pull rod has friction texture on both sides, and the friction texture is made of rubber. The friction texture can effectively reduce the friction when the operator uses the switch, prevent the operator's fingers from slipping and causing the switch to slide. In addition, the rubber material can prevent static electricity, preventing the operator from letting go due to static electricity when using the switch.

[0013] Preferably, there are three main limiting holes, which are opened sequentially from left to right. The three main limiting holes can fix the three working states of the switch.

[0014] Preferably, there are two switch limiting holes, which are sequentially opened from bottom to top on the pull rod. When the switch is in use or in the closed state, the pin can be inserted into the limiting hole to fix the switch.

[0015] Preferably, the main limiting hole and the switch limiting hole are connected to a limiting pin. A magnet mounting block is installed on the top of the circuit breaker and is installed behind the switch. A magnet is installed on the side of the magnet mounting block facing the switch. After the pin is inserted into the main limiting hole and the switch limiting hole, the switch can be effectively fixed to prevent the switch from shaking. The magnet can also generate an attractive force on the pin to prevent the pin from falling off.

[0016] Preferably, the width of the rotating groove is greater than the length of the pull rod, and the rotating groove allows the pull rod to be rotated more conveniently within the groove.

[0017] Preferably, the limiting shell is bolted and detachably mounted on the top of the circuit breaker, allowing for quick disassembly by unscrewing the bolts when maintenance or replacement is required. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A circuit breaker that is easy to connect in series includes a circuit breaker 1, a limiting shell 2 installed at the top of the circuit breaker 1, a switch 3 connected to the top of the circuit breaker 1 and the switch 3 being located inside the limiting shell 2, the switch 3 including a rotating ring 4 and a pull rod 5, the rotating ring 4 being installed on the top of the circuit breaker 1, the top of the rotating ring 4 being connected to the pull rod 5, main limiting holes 10 being equally spaced on the outer side of the limiting shell 2, a rotating groove 9 being provided inside the limiting shell 2, and a switch limiting hole 8 adapted to the main limiting hole 10 being provided at the front end of the pull rod 5.

[0025] like Figures 1-4As shown, a circuit breaker designed for easy series connection is provided. The pull rod 5 has friction grooves 6 on both sides, made of rubber. These grooves effectively reduce friction when the operator uses the switch 3, preventing slippage and ensuring the switch 3 stays in place. The rubber material also provides anti-static properties, preventing the operator from releasing the switch due to static electricity. Three main limit holes 10 are provided, arranged from left to right, allowing the switch 3 to be fixed in all three operating states. Two switch limit holes 8 are provided, arranged from bottom to top on the pull rod 5. When the switch 3 is in use or closed, a pin can be inserted into the limit hole to secure the switch 3. The main limit hole 10 and the switch limit hole 8 are connected to the limit pin 11. The top of the circuit breaker 1 is equipped with a magnet mounting block 12, which is installed behind the switch 3. A magnet 13 is installed on the side of the magnet mounting block 12 facing the switch 3. After the pin 11 is inserted into the main limit hole 10 and the switch limit hole 8, it can effectively fix the switch 3 and prevent the switch 3 from shaking. The magnet 13 can also generate a magnetic force on the pin 11 to prevent the pin 11 from falling off. The width of the rotating groove 9 is larger than the length of the pull rod 5. The rotating groove 9 allows the pull rod 5 to be rotated more conveniently in the groove. The limit shell 2 is installed on the top of the circuit breaker 1 by bolts. When maintenance or replacement is required, it can be quickly disassembled by unscrewing the bolts.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] When using the circuit breaker 1, because friction grooves 6 are provided at the top switch 3 of the circuit breaker 1, the operator will not make a mistake when pushing the switch 3 due to factors such as hand slippage. After the operator has been working for a long time, the pin 11 can be inserted into the main limit hole 10 on the outside of the limit housing 2 and then into the switch limit hole 8 on the pull rod 5 to fix the switch 3, preventing the circuit breaker 1 from being damaged due to the switch 3 loosening. In addition, the end of the pin 11 contacts the magnet 13, and the magnet 13 generates a magnetic force on the pin 11 to prevent the pin 11 from falling off.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
