However, this structural setting requires isolation between each phase line through a partition to ensure the electrical isolation effect between each phase line. However, the fixing strength of the wire is not high during the assembly process, and the electrical effect after assembly is not good, so an assembly method that is easy to install and ensures the electrical connection effect is needed. Summary of the invention

[0003] The main technical problem solved by the present invention is to provide a structure for separating the output end and the input end of a circuit breaker.

[0005] First, the input end and the output end are connected through a circuit breaker unit, so that the input end and the output end are electrically connected. The output end and the base are detachably connected, so that the input end and the output end form a separated structure. During the assembly process of the input end, the output conductive sheet is connected to the connection end to form a fixed connection. The connection method here is specifically through bolt connection, which ensures the strength of the connection and the effect of the electrical connection.

[0006] Among them, a connection hole I is provided on the connection end, a connection hole II is provided on the output conductive sheet, and a bolt passes through the connection hole I and is fixed to the connection hole II.

[0007] By setting the connection holes, the overall connection is better fixed and the bolt connection is more convenient.

[0008] Wherein, a mutual inductor is arranged on the output end, and the output conductive sheet passes through the mutual inductor and is connected to the connection end.

[0009] The setting of the mutual inductor increases the overall function of the circuit breaker and can monitor the current size of each phase line in real time.

[0010] Among them, it also includes a knife switch module, which includes a knife switch, and the lower end of the knife switch is connected to a driving rod; the output end is provided with a circuit board, a push rod and a motor drive mechanism, and the circuit board controls the movement of the motor drive mechanism to push the driving rod to move; the driving rod is located on the motion trajectory of one end of the push rod, and the other end of the push rod passes through the output end to the outside of the output end.

[0011] Automatic tripping controls the movement of the motor drive mechanism through the circuit board, so that it pushes the drive rod to move to achieve the tripping effect. Here, the motor drive mechanism is located in the output end housing to form a hidden effect; manual tripping is achieved through a push rod. By manually pressing the other end of the push rod, the push rod moves, pushing the drive rod to move, thereby achieving the tripping effect. The push rod is also located in the output end housing and only partially extends out of the output housing. Therefore, the manual and automatic integrated setting makes tripping more convenient. The overall mechanism is also simple and the hidden effect is better.

[0012] Among them, the push rod includes a pushing part, a connecting part and a driving part. The pushing part is connected to the driving part through the connecting part. The driving rod is located on the motion trajectory of the driving part. A through groove adapted to the push rod is provided in the output end. The connecting part is horizontally arranged, and the pushing part and the connecting part are vertically connected.

[0013] A through slot is provided in the output end, and the connecting part can slide in the through slot to achieve a sliding effect. The connecting part is horizontally arranged, so the sliding is more stable. The pushing part and the connecting part are vertically connected, which is more in line with human-computer interaction and more convenient to operate.

[0014] The motor drive mechanism comprises a motor, an output shaft is arranged on the motor, a spring is sleeved on the output shaft, and the movement of the output shaft causes the drive rod to move.

[0017] The output end is connected and fixed to the upper cover through the output end housing, and the circuit board is installed on the top of the output end housing, forming the structure of the output end, so that the output end can have a multi-functional effect. The LCD screen and buttons can be set on the circuit board, and the data of each phase line can be observed in real time. The upper cover and the base are detachably connected. It is very convenient to install the output end as a whole on the base and then fix it with bolts.

[0018] Among them, an extension portion is provided on one side surface of the top of the output end shell, a socket is provided on the extension portion, at least two second positioning columns are provided on the top of the output end shell, a protrusion and a second positioning hole are provided on the circuit board, the protrusion is extended into the socket and fixed, the second positioning hole and the second positioning column are fixed together; the socket and the second positioning column form a triangle fixation.

[0019] First, during the assembly process, the circuit board needs to extend the protrusion into the socket to fix it, and then the positioning hole and the positioning column are fixed together to achieve a triangular fixing structure, making the overall fixing effect firm and stable. With this structural setting, during the assembly process, it can be fixed without bolts. In addition, after fixing, due to the role of the socket, the circuit board cannot move up and down, and the setting of the positioning column prevents the circuit board from moving forward, backward, left, and right, achieving bolt-free fixing.

[0020] Among them, a fixing hole is provided on the output end, a fixing column is provided on the base, and bolts pass through the fixing hole and the fixing column, so that the output end module is connected and fixed to the base.

[0021] By setting the fixing holes and the fixing columns and then fixing with bolts, the overall fixation is made more firm and stable.

[0022] Among them, a first positioning hole is arranged on the bottom of the output end module, a first positioning column is arranged on the base, and the first positioning hole is fixedly matched with the first positioning column.

[0023] The provision of the first positioning hole and the first positioning column makes the installation more precise and ensures greater convenience during the assembly process. BRIEF DESCRIPTION OF THE DRAWINGS

The input terminal 7 is electrically connected to the output terminal 6 through the circuit breaker unit 5.

[0043] A housing chamber 21 is provided in the base 2, and a groove 22 adapted to the circuit breaker unit 5 is provided on the housing chamber 21. The number of grooves 22 can be three or four, which can be adjusted according to the actual number of phase lines. This embodiment is described by taking three grooves 22 as an example. Further, in order to ensure that the circuit breaker unit 5 does not fall off in the groove 22, a stopper 24 is provided above the input terminal 23, so that one end of the circuit breaker unit 5 abuts against the groove 22, and the other end abuts against the stopper 24. A convex rib 25 is provided on the side of the housing chamber 21, and a notch 51 is provided on the top of the circuit breaker unit 5, and the convex rib 25 abuts against the notch 51. The arrangement of the convex rib 25 and the notch 51 allows the circuit breaker unit 5 to be further fixed, and the notch 51 is located on the side of the circuit breaker unit 5 facing the output terminal 6.

[0044] A first guide surface 52 is provided on the bottom surface of the circuit breaker unit 5. The provision of the first guide surface 52 makes installation more convenient.

[0045] The circuit breaker unit 5 is provided with an input conductive sheet 53, and the input end 7 is provided with an input terminal 23. The input conductive sheet 53 extends from the accommodating chamber 21 and is connected to the input terminal 23. The input conductive sheet 53 extends from the accommodating chamber 21 to the outside of the base 2 and is electrically connected to the input terminal 23, so the connection is simple and convenient.

[0046] The knife module 4 is located above the circuit breaker unit 5 and fixed to the circuit breaker unit 5 by bolts. The knife module 4 includes a knife 41, which is linked to realize opening and closing. The lower end of the knife 41 is connected with a driving rod 42, and the driving rod 42 can achieve a tripping effect. The knife module 4 is also provided with a driving member 43, which is rotatably connected to the molded case circuit breaker 1, and the driving rod 42 is located on the motion track of the driving member 43, where the driving member 43 can be reset by a spring or a torsion spring.

[0047] The output end 6 is provided with an output end housing 61, a circuit board 62 and a second upper cover 63. The circuit board 62 is fixed on the top of the output end housing 61. The second upper cover 63 is detachably connected with the output end housing 61 and is sleeved on the top of the output end housing 61, so that the circuit board 62 is located between the output end housing 61 and the second upper cover 63. A liquid crystal display 621 and a button 622 are provided above the circuit board 62. The liquid crystal display 621 and the button 622 both extend from the second upper cover 63 to form an indication effect of the circuit board 62. Here, the top surfaces of the first upper cover 3 and the second upper cover 63 are flush, and the two fit together, so that the base 2 is closed.

[0048] A protrusion 623 and at least two second positioning holes 624 are provided on the circuit board 62. The number of the second positioning holes 624 can be increased according to actual needs. In this embodiment, only two second positioning holes 624 are used as an example. The protrusion 623 is specifically located on one side of the circuit board 62. Specifically, a protrusion 623 is formed by two notches 625 to ensure that one side of the circuit board 62 is flat. The two second positioning holes 624 are located on the other side of the circuit board 62, so that a protrusion 623 and the imaginary center connection line of the two second positioning holes 624 form a triangular structure to ensure the overall fixing effect. Here, it is preferably an obtuse triangle to ensure that the circuit board 62 can be stably fixed on the output end housing 61.

[0049] A protrusion 614 is provided on one side of the top of the output end housing 61. Specifically, the protrusion 614 extends vertically upward. A plug hole 615 is provided on the protrusion 614. The plug hole 615 corresponds to the protrusion 623 on the circuit board 62. The length of the plug hole 615 is greater than the length of the protrusion 623. The length of the plug hole 615 is set to ensure that the protrusion 623 can be better inserted into the plug hole 615, so as to achieve a single-side fixing effect. A blocking plate 616 is provided on the same side of the protrusion 614 so that the circuit board 62 will not be offset during the fixing process.

[0050] Two bosses 617 are provided on the other side of the top of the output end housing 61. Here, the bosses 617 are located on the side of the output end housing 61, and the top of the bosses 617 is flush with the top of the output end housing 61. Two second positioning columns 618 are provided on the bosses 617. The second positioning columns 618 correspond to the second positioning holes 624 on the circuit board 62, and the circuit board 62 is fixed by the second positioning columns 618. Here, for the convenience of fixing, the second positioning columns 618 are provided with second guide surfaces 619.

[0051] The connection structure between the output terminal 6 and the base 2 is that the output terminal 6 partially extends into the base 2, that is, the output terminal shell 61 is located in the base 2, and a first positioning hole 611 and a positioning protrusion 612 are provided on the bottom of the output terminal shell 61, and a first positioning column 26 and a positioning guide protrusion 27 are provided on the base 2. The first positioning hole 611 is fixed with the first positioning column 26, and the setting of the positioning protrusion 612 and the positioning guide protrusion 27 further reduces the difficulty of assembly. Here, the positioning protrusion 612 is set in a triangle.

[0052] The output end 6 as a whole is connected and fixed to the base 2 through the second upper cover 63. Specifically, the second upper cover 63 is provided with a fixing hole 631, and the base 2 is provided with a fixing column 28. Bolts pass through the fixing hole 631 and the fixing column 28 to fix the second upper cover 63 to the base 2. The setting of the fixing hole 631 and the fixing column 28 and then fixing with bolts make the overall fixation more firm and stable.

[0053] The second upper cover 63 is detachably connected to the output end housing 61. Specifically, a clamping slot 632 is provided on the second upper cover 63, and a clamping protrusion 613 corresponding to the clamping slot 632 is provided on the output end housing 61. The two cooperate to form a fixation. The number of the clamping protrusions 613 here can be increased or decreased according to actual needs. The preferred solution of this embodiment is that one clamping protrusion 613 is provided on each of the left and right sides, one clamping protrusion 613 is provided on the front side, and two clamping protrusions 613 are provided on the rear end, so that all sides are clamped and fixed.

[0054] The second upper cover 63 is provided with a flip cover 633, and the flip cover 633 is rotatably connected to the second upper cover 63. Specifically, the second upper cover 63 is provided with a shaft hole, and the flip cover 633 is provided with a shaft, which is inserted into the shaft hole and fixed to form a rotatable connection. The setting of the flip cover 633 allows the user to view the indication information on the circuit board 62 through the flip cover 633, and also plays a dustproof and waterproof effect, thereby better protecting the circuit board 62.

[0055] Furthermore, the flip cover 633 is transparent, so that the user can observe the indication information on the circuit board 62 without opening the flip cover 633, which is more convenient and intuitive.

[0056] The output end housing 61 is provided with a mutual inductor 64 and an output conductive sheet 65. The output end housing 61 is provided with a mounting cavity 8. The number of mounting cavities 8 is consistent with the number of phase lines of the molded case circuit breaker 1, which is three here. The structure of each mounting cavity 8 is the same. The only difference is that the connection between the bottom surface of the mounting cavity 8 in the middle and the two side surfaces is provided with an inclined surface 81. The rest of the structures are similar, so the description is not repeated here, and only the structure of one mounting cavity 8 is described. The mounting cavities 8 here are all formed by integral plastic molding.

[0057] The mounting cavity 8 is an open cavity, that is, the top surface is set as an opening, and the opening is mainly used for the assembly of the mutual inductor 64. A trapezoidal opening 82 is provided on the bottom surface of the mounting cavity 8. The trapezoidal opening 82 is used for the extension of the conductive sheet, which connects the input and output ends. The trapezoidal opening 82 is a structure that is small at the top and large at the bottom. The width of the conductive sheet is adapted to the lower end of the trapezoidal opening 82 to form a snap-fit ​​fixation. The setting of the trapezoidal opening 82, first, improves the heat dissipation effect of the output conductive sheet 65, and second, enables the output conductive sheet 65 to have a fixing effect. It should be noted here that a through hole 641 is provided on the mutual inductor 64, and one end of the output conductive sheet 65 extends from the trapezoidal opening 82 to be connected to the output terminal, and the other end of the output conductive sheet 65 extends from the through hole 641 to be connected to the connection end, so that an electrical connection is formed. Here, the output conductive sheet 65 is Z-shaped.

[0058] The height of the installation cavity 8 is greater than the height of the mutual inductor 64, and the height difference is 0.1-1mm, so that the mutual inductor 64 can move slightly in the installation cavity 8, which is mainly used for the assembly of the mutual inductor 64. The installation cavity 8 is detachably connected to the mutual inductor 64, and its specific structure is that a protrusion 83 is provided on the side of the installation cavity 8, and a first card groove 642 adapted to the protrusion 83 is provided on the side of the mutual inductor 64. The cooperation between the protrusion 83 and the first card groove 642 realizes the connection and fixation between the mutual inductor 64 and the installation cavity 8. An inclined surface 81 is provided between the bottom surface and the side surface of the installation cavity 8, and a supporting rib 811 is provided on the inclined surface 81. The function of the supporting rib 811 is to increase the strength of the inclined surface 81 to prevent the inclined surface 81 from being broken due to excessive pressure during the assembly process.

[0059] Furthermore, a third guide surface 84 is provided on the side of the installation cavity 8. The provision of the third guide surface 84 better meets the assembly effect between the mutual inductor 64 and the installation cavity 8.

[0060] Furthermore, a first guide slot 85 is provided on the lower end surface of the installation cavity 8. The first guide slot 85 is provided so that the mutual inductor 64 can be guided by the first guide slot 85 during the assembly process, making the assembly easier.

[0061] At the same time, in order to further prevent the mutual inductor 64 from sliding out of the installation cavity 8, a blocking member 86 is provided on the open end of the installation cavity 8, and the blocking member 86 can be located at any position of the open end, preferably at the top of the first guide slot 85. The blocking member 86 is specifically a barb, and the first guide slot 85 is located directly below the barb. When the mutual inductor 64 is installed in the installation cavity 8, the mutual inductor 64 can be located below the barb by sliding to achieve a blocking and fixing effect.

[0062] Furthermore, a fourth guide surface 861 is provided on the outer side of the blocking member 86. The fourth guide surface 861 on the blocking member 86 makes the mutual inductor 64 more convenient to assemble.

[0063] The circuit breaker unit 5 is provided with a connection terminal 54, the base 2 is provided with an output terminal 29, one end of the output conductive sheet 65 is connected to the output terminal 54, specifically fixed by bolt connection, and the other end of the output conductive sheet 65 passes through the mutual inductor 64 and is electrically connected to the output terminal 29. The connection terminal 54 is provided with a connection hole I 541, and the output conductive sheet 65 is provided with a connection hole II 651, and the bolt passes through the connection hole I 541 and is fixed with the connection hole II 651. Here, since the output conductive sheet 65 is Z-shaped, the connection between the output conductive sheet 65 and the connection terminal 54 is an oblique connection to ensure the stability of the electrical connection, and the oblique angle here is preferably 45°.

[0064] The output conductive sheet 65 is provided to make the connection more convenient, and the module 6 is connected to the circuit breaker unit 5 via the output terminal 54, so the assembly is more convenient.

[0065] The output end housing 61 is provided with a receiving chamber 610 and a through slot 6101, and the receiving chamber 610 is in a communicating state with the through slot 6101. The receiving chamber 610 is provided with a motor drive mechanism 9, and the through slot 6101 is used to place a push rod 91, and the push rod 91 slides in the through slot 6101. The top of the receiving chamber 610 is provided with a through hole 6102, and the through hole 6102 is communicated with the circuit board 62, so as to form an electrical connection between the circuit board 62 and the motor drive mechanism 9. The motor drive mechanism 9 includes a motor 92, and the motor 92 is provided with an output shaft 921, and the output shaft 921 is sleeved with a spring 922, and the output shaft 921 moves axially upward.

[0066] The push rod 91 includes a push portion 911, a connection portion 912 and a driving portion 913. The push portion 911 is connected to the driving portion 913 through the connection portion 912. The driving member 43 is located on the motion track of the driving portion 913. The connection portion 912 is horizontally arranged and located in the through slot 6101, and can slide in the through slot 6101. A blocking block 915 is provided on the connection portion 912, and the output end housing 61 is located on the motion track of the blocking block 915. The push portion 911 and the driving portion 913 are both vertically connected to the connection portion 912, so that the push rod 91 meets the pushing effect. Further, a guide block 914 is provided at the connection between the connection portion 912 and the driving portion 913. The guide block 914 fits the top of the through slot 6101 to form a guiding effect to prevent the push rod 91 from deviating during the movement. The driving portion 913 is composed of a vertical surface and an inclined surface. The inclined surface is connected to the bottom end of the vertical surface, and the inclined surface is obliquely arranged toward the connection portion 912. The push rod 91 is integrally formed of plastic. It should be noted that the second upper cover 63 is provided with a receiving groove 916 adapted to the push portion 911, and the receiving groove 916 is connected to the through groove 6101. The push portion 911 partially extends out of the receiving groove 916, and the excess dimension is less than 5mm, which does not affect the overall shape, and can form a convex shape for easy pressing.

[0067] The second upper cover 63 is provided with a baffle 634 and an elastic baffle 635. The baffle 634 is connected to the second upper cover 63 in a rotational manner. Specifically, the second upper cover 63 is provided with a shaft hole, and shafts are provided at both ends of the baffle 634. The shafts extend into the shaft holes so that the baffle 634 is connected to the second upper cover 63 in a rotational manner. The baffle 634 is located on the motion track of the output shaft 921. A plug 6341 is provided on one side of the baffle 634. The plug 6341 is inserted into the accommodating cavity 610 to form a guide fixation. The elastic baffle 635 is located on the motion track of the baffle 634. When the output shaft 921 extends out, the baffle 634 is pushed to move. The baffle 634 drives the driving rod 42 to move to achieve the release. However, due to the setting of the elastic baffle 635, the baffle 634 cannot be overturned. After the release is completed, the output shaft 921 is reset. Due to the effect of gravity, the baffle 634 automatically slides down and returns to its original position.

During the assembly process of the input terminal 7, the output conductive sheet is connected to the connection end to form a fixed connection. The connection method here is specifically through bolt connection, which ensures the strength of the connection and the effect of the electrical connection.
