[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. When a power system has leakage, overload, short circuit or other faults, it can quickly cut off the faulty mechanism in the power system or cut off the entire power supply to prevent the fault from expanding and causing huge economic losses and casualties.

In short, in the same module assembly 20, the two terminal modules located on both sides of the control module 24 can be fixedly connected to the control module 24 in the same manner or in different manners, and this application does not limit this.

[0049] The base body 10 is located below the module assembly 20, and the module assembly 20 is fixedly connected to the base body 10 along the second direction b. The first direction a is perpendicular to the second direction b. Figure 1 shown.

[0050] It should be noted that the specific fixing connection method between the base body 10 and the module assembly 20 is not limited in this application, and those skilled in the art can choose according to needs, such as fixing the connection with screws or rivets, or fixing the connection with a snap-on method.

[0051] For example, optionally, the base body 10 and the module assembly 20 are fixedly connected by a buckle structure.

[0052] The buckle 234 can be respectively arranged on the first terminal module 21 and the second terminal module 22 of the module assembly 20, and the buckle groove 11 is also correspondingly arranged at the position of the base body 10 corresponding to the buckle 234. Of course, the buckle 234 and the buckle groove 11 can also be interchanged, that is, the buckle groove 11 is arranged on the module assembly 20, and the buckle 234 is arranged on the base body 10.

[0053] In summary, the circuit breaker base provided by the present application includes a base body 10, a first terminal module 21, a second terminal module 22 and a control module 24; the first terminal module 21 and the second terminal module 22 are distributed on opposite sides of the control module 24 along a first direction a, and are respectively fixedly connected to the control module 24 to form a module assembly 20, and the module assembly 20 is fixedly connected to the base body 10 along a second direction b, and the first direction a and the second direction b are perpendicular. The present application forms the module assembly 20 by fixing the first terminal module 21 and the second terminal module 22 on opposite sides of the control module 24, respectively, so that the connection reliability of the module assembly 20 can be improved; after the first terminal module 21, the second terminal module 22 and the control module 24 are assembled together to form the module assembly 20, the module assembly 20 is then installed on the base body 10, so that the connection reliability and structural stability of the overall structure of the circuit breaker base can be improved.

[0054] The present application does not limit the specific types of the first terminal module 21 and the second terminal module 22. Optionally, the first terminal module 21 and the second terminal module 22 are both wiring terminal modules; or, the first terminal module 21 and the second terminal module 22 are both phase-changing terminal modules; or, the first terminal module 21 is a wiring terminal module and the second terminal module 22 is a phase-changing terminal module; or, the first terminal module 21 is a phase-changing terminal module and the second terminal module 22 is a wiring terminal module.

[0055] That is, the first terminal module 21 and the second terminal module 22 in the module assembly 20 may both be connection terminal modules, or both be phase-changing terminal modules, or one of them may be a connection terminal module and the other may be a phase-changing terminal module.

[0056] To facilitate the fixation of the first terminal module 21 and the second terminal module 22 to the control module 24 respectively, optionally, the first terminal module 21 and / or the second terminal module 22 is provided with a first mating portion, and the control module 24 is provided with a second mating portion on a side close to the first terminal module 21 and / or the second terminal module 22, and the first mating portion and the second mating portion are plugged into each other.

[0057] In this way, the first terminal module 21 and / or the second terminal module 22 can be respectively plugged and positioned with the control module 24 by the cooperation of the first matching part and the second matching part, and then fixed by a specific fixing method (such as snap fixing or screw or rivet fixing).

[0058] It should be noted that the first terminal module 21 and the second terminal module 22 may both be provided with a first matching portion, or one of them may be provided with the first matching portion; correspondingly, the control module 24 may be provided with a second matching portion on both the side close to the first terminal module 21 and the side close to the second terminal module 22, or one of them may be provided with the second matching portion. That is to say, in this embodiment, the plug-in matching of the first terminal module 21, the second terminal module 22 and the control module 24 may be that the first terminal module 21 and the second terminal module 22 both adopt the matching mode of the first matching portion and the second matching portion, or one of them adopts the matching mode of the first matching portion and the second matching portion, and the other adopts other matching modes, and this application does not limit this.

[0059] The first matching part may be a plug-in structure 231, and the second matching part may be a snap-in slot 241; or the first matching part may be a snap-in slot 241, and the second matching part may be a plug-in structure 231. The following mainly takes the first matching part being a plug-in structure 231 and the second matching part being a snap-in slot 241 as an example for illustration.

[0060] It should be noted that when the first matching portion is a plug-in structure 231 and the second matching portion is a snap-in groove 241, the terminal module and the control module 24 can be fixed by rivets or screws, or by snap-fitting.

[0061] In the first possible implementation, please refer to Figures 1 to 6 As shown, optionally, the first matching portion is a plug-in structure 231, and the second matching portion is a snap-in groove 241; the plug-in structure 231 is plugged into the snap-in groove 241 of the control module 24, and the plug-in structure 231 and the control module 24 are fixedly connected by rivets or screws.

[0062] That is, the plug-in structure 231 is first plugged into the card slot 241 of the control module 24, and then the plug-in structure 231 and the control module 24 are fixedly connected by screws or rivets. Figure 3 The mouth shape shown can also be Fig.13 As shown in the inverted convex shape, the present application does not impose any limitation on the structure of the snap-in slot 241 , as long as the snap-in slot 241 can accommodate the plug-in structure 231 for easy positioning.

[0063] Please refer to Figure 2 and Figure 3As shown, optionally, the plug-in structure 231 is fixedly connected to the control module 24 by rivets or screws; a first extension structure 232 is provided on a side of the plug-in structure 231 close to the base body 10 and extends toward the base body 10, and a second extension structure 242 is provided on a side of the control module 24 close to the base body 10 and extends toward the base body 10, and the first extension structure 232 and the second extension structure 242 are arranged along a first direction a; when the plug-in structure 231 is inserted into the clamping groove 241, the first extension structure 232 and the second extension structure 242 can abut and cooperate with each other on the sides thereof.

[0064] That is, a first extension structure 232 may be further provided on a side of the plug-in structure 231 close to the base body 10, so that the first extension structure 232 may abut against and cooperate with the second extension structure 242 of the control module 24 in the first direction a. Figure 2 and Figure 3 As shown, in this embodiment, when the plug-in structure 231 is plugged into the snap-in groove 241, the opposing sides of the first extension structure 232 and the second extension structure 242 can abut against each other, thereby enhancing the connection stability between the first terminal module 21 and / or the second terminal module 22 and the control module 24 and preventing large deflection.

[0065] It should be noted that, in this embodiment, the first extension structure 232 and the second extension structure 242 may be matched by surface contact, such as Figure 2 and Figure 3 As shown, in this way, the contact area between the corresponding terminal module and the control module 24 can be increased, and the deflection amplitude can be effectively reduced.

[0066] Optionally, the first terminal module 21 and the second terminal module 22 further have a first limiting structure 233, respectively, and the control module 24 is provided with a second limiting structure 243 adapted to the first limiting structure 233, and the first limiting structure 233 and the second limiting structure 243 are plugged and matched along the first direction a, such as Figure 2 and Figure 3 shown.

[0067] The first limiting structure 233 and the second limiting structure 243 are matched in a plug-in connection manner. For example, the first limiting structure 233 is a protruding structure, and the second limiting structure 243 is a groove structure. Figure 2 and Figure 3 As shown; or, in other embodiments, the first limiting structure 233 can be a groove structure, and the second limiting structure 243 can be a protrusion structure, which is not limited in the present application.

[0068] In addition, in this embodiment, the first limiting structure 233 and the first extending structure 232 are located on the same side of the corresponding terminal module. The first limiting structure 233 extends from the corresponding terminal module toward the control module 24. Figure 2 As shown; or, the second limiting structure 243 extends from the control module 24 toward the corresponding terminal module on one side of the corresponding terminal module.

[0069] On the basis of the cooperation between the first extension structure 232 and the second extension structure 242, the cooperation between the first limiting structure 233 and the second limiting structure 243 is superimposed, so that the abutment surface between the control module 24 and the corresponding terminal module can be further increased, thereby effectively reducing the deflection amplitude and improving the connection reliability of the module assembly 20.

[0070] In the second possible implementation, please refer to Figures 7 to 12 As shown, optionally, the first matching portion is a plug-in structure 231 , and the second matching portion is a snap-in groove 241 ; the plug-in structure 231 is plugged into the snap-in groove 241 of the control module 24 , and the plug-in structure 231 is snap-connected with the control module 24 .

[0071] That is to say, in this implementation, the plug-in structure 231 is inserted into the engaging groove 241 , and the plug-in structure 231 is engaged with the control module 24 .

[0072] Alternatively, if Figure 8 and Fig. 9 As shown, the plug-in structure 231 is engaged with the control module 24, and the plug-in structure 231 includes a first body 2311, a pressing member 2312, and a cantilever beam 2313 connected between the first body 2311 and the pressing member 2312; the engaging groove 241 includes a containing cavity 2411 provided in the control module 24, and a first sub-groove 2412 and a second sub-groove 2413 respectively provided on a side plate of the control module 24 close to the plug-in structure 231; the first sub-groove 2412, the second sub-groove 2413 and the containing cavity 2411 are connected in pairs; When the first body 2311 is driven to be inserted into the accommodating chamber 2411 through the first sub-groove 2412, the pressing piece 2312 is driven to move toward the direction close to the first body 2311, and the cantilever beam 2313 is pressurized to store energy and can be inserted into the accommodating chamber 2411 through the second sub-groove 2413; the cantilever beam 2313 releases energy, and the side of the cantilever beam 2313 facing the second sub-groove 2413 can abut and cooperate with the inner wall of the accommodating chamber 2411 close to the second sub-groove 2413, so that the first body 2311 and the cantilever beam 2313 are locked in the accommodating chamber 2411.

[0073] The specific structure of the plug-in structure 231 can be referred to Fig.11 and Fig.12As shown, the plug-in structure 231 includes a first body 2311, a cantilever beam 2313 and a pressing member 2312 connected in sequence. In this embodiment, the pressing member 2312 is driven to move toward the direction of the first body 2311, and the cantilever beam 2313 can store energy. That is, in this embodiment, the cantilever beam 2313 has a certain elasticity.

[0074] The above-mentioned card slot 241 can refer to Fig.13 and Fig.14 As shown, the card slot 241 includes a receiving cavity 2411, a first sub-groove 2412 and a second sub-groove 2413. When the plug-in structure 231 is inserted into the control module 24, the first body 2311 is inserted into the receiving cavity 2411 through the first sub-groove 2412.

[0075] It should be noted that when the plug-in structure 231 is inserted into the control module 24, Fig. 9 As shown, it is necessary to drive the pressing piece 2312 to move in the direction of the first body 2311, so that the cantilever beam 2313 can be pressurized to store energy and compress the distance from the first body 2311, so as to be inserted into the accommodating cavity 2411 through the second sub-groove 2413; in this way, after the first body 2311 and the cantilever beam 2313 are plugged into place, after the drive of the pressing piece 2312 is released, the cantilever beam 2313 can release energy. At this time, the cantilever beam 2313 is reset to enable its end close to the pressing piece 2312 to abut and cooperate with the inner wall surface of the accommodating cavity 2411 close to the second sub-groove 2413, so that the cantilever beam 2313 is locked in the accommodating cavity 2411.

[0076] It is worth noting that when the plug-in structure 231 needs to be removed from the snap-in groove 241, the pressing piece 2312 is driven to move in the direction of the first body 2311, and the cantilever beam 2313 stores energy and compresses the distance from the first body 2311. In this way, the cantilever beam 2313 can be removed from the accommodating cavity 2411 through the second sub-groove 2413, and the first body 2311 can be removed from the accommodating cavity 2411 through the first sub-groove 2412, and the plug-in structure 231 and the control module 24 are unlocked.

[0077] In order to facilitate the storage of the pressing piece 2312, optionally, the snap-in slot 241 also includes a third sub-groove 2414 provided on the side panel of the control module 24 close to the plug-in structure 231, and the third sub-groove 2414 is located on the side of the second sub-groove 2413 away from the first sub-groove 2412, and is respectively connected to the second sub-groove 2413 and the accommodating chamber 2411; when the side of the cantilever beam 2313 facing the inner wall of the second sub-groove 2413 abuts against the inner wall of the accommodating chamber 2411 close to the second sub-groove 2413, one end of the pressing piece 2312 close to the first body 2311 is located in the third sub-groove 2414 and the other end extends out from the third sub-groove 2414.

[0078] The third sub-groove 2414, the second sub-groove 2413 and the first sub-groove 2412 are respectively connected to the accommodating cavity 2411, and the second sub-groove 2413 is connected to the first sub-groove 2412 and the third sub-groove 2414. The third sub-groove 2414 is provided in the present application, so that when the plug-in structure 231 is inserted into the clamping groove 241, the pressing member 2312 can be received in the third sub-groove 2414.

[0079] In addition, when the plug-in structure 231 is inserted into the snap-in groove 241, the end of the pressing piece 2312 close to the first body 2311 can be accommodated in the third sub-groove 2414, while the end close to the base body 10 extends out from the third sub-groove 2414. In this way, the user can press the pressing piece 2312 through the end of the pressing piece 2312 close to the base body 10 to drive the pressing piece 2312 to move toward the first body 2311.

[0080] To avoid reverse installation of the module assembly 20 and the base body 10, optionally, refer to Figure 3 and Figure 4 The base body 10 is provided with a first fool-proofing structure 12, and the control module 24 is provided with a second fool-proofing structure 245 adapted to the first fool-proofing structure 12, and the first fool-proofing structure 12 and the second fool-proofing structure 245 are pluggable and matched along the second direction b.

[0081] The first fool-proofing structure 12 may be a protruding structure, and the second fool-proofing structure 245 may be a corresponding groove structure; or vice versa.

[0082] Optionally, see Figure 5 and Figure 6 As shown, the first anti-foolproof structure 12 is an anti-foolproof rib, and the second anti-foolproof structure 245 is an anti-foolproof hole; when the anti-foolproof rib is inserted into the anti-foolproof hole, one side of the anti-foolproof rib abuts against the connector 246 in the control module 24, and the anti-foolproof rib and the connector 246 are arranged along the third direction e, and the third direction e, the first direction a and the second direction b are perpendicular to each other.

[0083] That is to say, the first fool-proof structure 12 of the present application can not only be used to prevent fool-proofing, but also can be used to support the connector 246 .

[0084] It should be noted that a connector 246 is provided in the control module 24. Since the internal structure of the control module 24 is not convenient for designing support features, when the existing multiple control modules 24 are spliced ​​along the third direction e, the pressure of the springs 247 will be applied between different control modules 24, resulting in unstable power supply and signal transmission. To this end, the anti-foolproof ribs designed in the present application can, on the one hand, achieve the purpose of anti-foolproofing, and on the other hand, support the connector 246 in the control module 24 to overcome the pressure of the springs 247. In this way, the stability of the power supply and signal transmission of the circuit breaker base can be improved on the basis of anti-foolproofing.

[0085] Another aspect of the present invention provides a power distribution device, which includes the above-mentioned circuit breaker base. Since the specific structure and technical effects of the circuit breaker base have been elaborated and explained in detail in the previous text, this application will not repeat them here. The power distribution device provided by this application adopts the circuit breaker base in the previous text, so that the connection reliability and structural stability of the overall structure of the circuit breaker base can be improved.

[0086] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0087] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
