Technical Field
[0001] This utility model belongs to the technical field of electrical connection mechanism, specifically relating to an assembly structure for an intelligent circuit breaker. Background Technology
[0002] Currently, when installing intelligent circuit breakers, most are directly connected to the rail via the snap-fit structure on the back of the circuit breaker to fix it on the rail. However, this type of snap-fit structure relies on the friction between the snap-fit and the rail for fixation. If the initial connection is not handled properly, it is easy for the circuit to fall off or loosen later, which may affect the safety of the circuit. Therefore, this kind of ordinary assembly connection structure lacks a further safety connection structure in actual use, and its connection safety is limited. Utility Model Content
[0003] The purpose of this utility model is to provide an assembly structure for an intelligent circuit breaker to solve the problems mentioned in the background art.
[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] The locking tongue assembly is a limiting device in the protection mechanism used to cooperate with the track for installing the circuit breaker body. The circuit breaker body has a mounting cavity on the lower side of the corresponding connecting slot. The locking tongue assembly is set in the mounting cavity and extends out of the mounting cavity. There is a gap between the locking tongue assembly and the inner wall of the connecting slot that matches the track. The upper side of the connecting slot has a slot that matches the position and size of the gap.
[0007] The regulator is a device in the protection mechanism used to control the state of the latch assembly. The regulator is disposed in the mounting cavity and connected and matched with the latch assembly. One side of the regulator extends out of the front end of the circuit breaker body.
[0008] The locking tongue assembly consists of a limiting locking tongue, a carrier plate, and tension springs. The carrier plate is slidably disposed within the mounting cavity. The locking tongue is connected to the carrier plate and extends out of the mounting cavity. The tension springs are of several types and are disposed between the carrier plate and the inner wall of the mounting cavity.
[0009] The regulator consists of a screw, a cross cap, a trapezoidal adjustment platform, and a connecting rod. The trapezoidal adjustment platform is slidably disposed in the mounting cavity, and in the initial state of the carrier plate, the horizontal height of the lowest side of the trapezoidal adjustment platform is higher than the horizontal height of the highest side of the trapezoidal adjustment platform. The trapezoidal adjustment platform has a hollow structure and a sliding groove at the inclined end.

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1-4As shown, an assembly structure of an intelligent circuit breaker includes a circuit breaker body 1, a connection slot 11 on the rear side of the circuit breaker body 1, and a protection mechanism provided on the lower side of the connection slot 11.
[0021] The locking tongue assembly is a limiting device in the protection mechanism used to cooperate with the track for installing the circuit breaker body 1. The circuit breaker body 1 has a mounting cavity 12 on the lower side of the corresponding connecting slot 11. The locking tongue assembly is set in the mounting cavity 12 and extends out of the mounting cavity 12. There is a gap between the locking tongue assembly and the inner wall of the connecting slot 11 that matches the track. The upper side of the connecting slot 11 has a slot 13 that matches the position and size of the gap.
[0022] The regulator is a device in the protection mechanism used to control the state of the latch group. The regulator is set in the mounting cavity 12 and connected and matched with the latch group. One side of the regulator extends out of the front end of the circuit breaker body 1.
[0023] When installing the circuit breaker body 1 onto the electrical box track, first insert the slot 13 on the upper side of the circuit breaker body 1 into the track, then flip the circuit breaker body 1 downwards so that the locking tongue assembly is squeezed by the track and retracts into the mounting cavity 12 until the track is embedded in the gap between the slot 13 and the locking tongue assembly, thereby completing the limiting connection of the circuit breaker body 1 under the limiting of the locking tongue assembly.
[0024] Once the connection is complete, the state of the latch assembly can be further restricted through the regulator. This allows for manual restriction of the opening and closing of the latch assembly, meeting the safety limit requirements after installation. It also helps to address situations where the latch assembly may jam and prevent the locking from being canceled during disassembly, replacement, or maintenance, making the installation and maintenance of the circuit breaker body 1 more convenient and faster.
[0025] The locking tongue assembly consists of a limiting locking tongue 2, a carrier plate 21, and a tension spring 22. The carrier plate 21 is slidably disposed in the mounting cavity 12. The locking tongue is connected to the carrier plate 21 and extends out of the mounting cavity 12. There are several tension springs 22 disposed between the carrier plate 21 and the inner wall of the mounting cavity 12.
[0026] In the initial state, the tension spring 22 keeps the carrier plate 21 in place to ensure that the limiting lock tongue 2 is extended out of the mounting cavity 12. When the inclined surface of the limiting lock tongue 2 is abutted by the track, the limiting lock tongue 2 retracts into the mounting cavity 12 until the track is locked between the limiting lock tongue 2 and the inner wall of the connecting slot 11 to form a connection. The spring tension of the tension spring 22 can maintain the limiting lock tongue 2 itself with a certain sliding resistance. In fact, in order to meet the needs of some application scenarios, the inclined surface of the lock tongue can be symmetrically distributed. That is, by directly flipping the circuit breaker body 1, the lock tongue can overcome the tension of the tension spring 22 and retract into the mounting cavity 12, and the circuit breaker body 1 can be disassembled.
[0027] The regulator consists of a screw 3, a cross cap 31, a trapezoidal adjustment platform 32, and a connecting rod. The trapezoidal adjustment platform 32 is slidably disposed in the mounting cavity 12, and the horizontal height of the lowest side of the carrier plate 21 is higher than the horizontal height of the highest side of the trapezoidal adjustment platform 32 in the initial state. The trapezoidal adjustment platform 32 has a hollow structure and a sliding groove 32 is opened at the inclined end. The trapezoidal adjustment platform 32 has a misalignment groove 33 at the end away from the inclined surface. The screw 3 is threadedly connected to the circuit breaker body 1 and extends into the mounting cavity 12 to be rotatably connected to the trapezoidal adjustment platform 32. The cross cap 31 is concentrically connected to the other end of the screw 3. The connecting rod is located at the lower end of the carrier plate 21 and extends into the hollow part of the trapezoidal adjustment platform 32.
[0028] In the initial state, both the screw 3 and the trapezoidal adjusting platform 32 are kept away from the locking tongue assembly. At the same time, the trapezoidal adjusting platform 32 is a hollow structure, so it will not affect the extension and retraction movement of the locking tongue assembly.
[0029] When it is necessary to manually fix and limit the installation of the circuit breaker body 1, the cross cover 31 can be rotated by a Phillips screwdriver or a flathead screwdriver, so that the screw 3 is gradually screwed into the installation cavity 12 until the upper end of the trapezoidal adjustment platform 32 forms a block against the carrier plate 21, thereby completing the limitation of the entire latch assembly. Conversely, when it is necessary to disassemble, the screw 3 is rotated in the opposite direction until the trapezoidal adjustment platform 32 removes the block against the carrier plate 21 and can be restored.
[0030] When the locking tongue assembly is worn out or the components are stuck, causing the limiting locking tongue 2 to be unable to reset by the tension spring 22, the screw 3 can be rotated outward. Under the action of the connecting rod and the trapezoidal adjusting table 32, the connecting rod will be pulled by the inclined surface of the trapezoidal adjusting table 32, thereby generating a downward pulling force. This can force the limiting locking tongue 2 to be pulled down, thus dealing with the environment where the components are stuck or malfunctioning.
[0031] The connecting rod consists of an extension rod 4 and a crossbar 41. The extension rod 4 has an L-shaped structure and is connected to the carrier plate 21. The crossbar 41 is located inside the trapezoidal adjustment platform 32 and is connected to the extension rod 4.
[0032] The extension rod 4 connects to and extends into the hollow part of the trapezoidal adjustment platform 32. The crossbar 41 is used to cooperate with the sliding groove of the trapezoidal adjustment platform 32, so that the trapezoidal adjustment platform 32 can generate a pulling force on the crossbar 41 when it moves backward. The misalignment groove serves to avoid the crossbar 41 when the trapezoidal adjustment platform 32 moves forward.
[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
