[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] This embodiment provides an asymmetric button structure. Figure 1-8 As shown, including:

[0041] The closing button 11 is installed in the housing 13. The closing button 11 is used for being pressed by an operator. The closing button 11 cooperates with an operating mechanism in the housing 13 to achieve a closing operation.

[0042] The opening button 12 is installed in the housing 13. The opening button 12 is used for pressing by an operator. The opening button 12 cooperates with the operating mechanism in the housing 13 to achieve the opening operation.

[0043] The part of the closing button 11 located on the front side of the housing 13 is different in shape from the part of the opening button 12 located on the front side of the housing 13. Here, the front side of the housing 13 specifically refers to the side of the operation panel, where the operator can observe the closing button 11 and the opening button 12. Different shapes specifically refer to the part where the operator can observe the closing button 11 and the opening button 12. For example, the closing button 11 is circular, and the opening button 12 can be square, or can be square, or can be oval, or can be triangular, etc. The opening button 12 can also be a special-shaped structure, and it is only necessary to ensure that the shapes of the parts of the closing button 11 and the opening button 12 located on the front side of the housing 13 are inconsistent. It should also be noted that the parts of the closing button 11 and the opening button 12 located in the housing 13 can have the same structure. The parts of the closing button 11 and the opening button 12 facing the front side are different in shape, and there can be a clear distinction. The operator operates according to the process file (which can also be the production file), and it is not easy to have assembly errors.

[0044] Specifically, as attached Figure 2-8 As shown, the front side of the housing 13 is provided with a first mounting cavity 131 and a second mounting cavity 132, the closing button 11 includes a first pressing portion 111, the first pressing portion 111 cooperates with the first mounting cavity 131, and the opening button 12 includes a second pressing portion 121, the second pressing portion 121 cooperates with the second mounting cavity 132. The first mounting cavity 131 and the second mounting cavity 132 form a guiding effect, so that the closing button 11 and the opening button 12 can better cooperate with the housing 13. The shapes of the first mounting cavity 131 and the second mounting cavity 132 can be consistent, for example, both are square, so that the closing button 11 and the opening button 12 can be accommodated in the corresponding cavity. The shapes of the first mounting cavity 131 and the second mounting cavity 132 can also be consistent, forming a one-to-one assembly effect. In addition, the opening button 12 and the closing button 11 can also directly cooperate with the housing 13, without the need for a cavity structure, and only one plane passes through.

[0045] Specifically, as attached Figure 2-8 As shown, the shapes of the first installation cavity 131 and the second installation cavity 132 are different. This structural setting forms a fool-proof structure, thereby avoiding errors during the assembly process. For example, when the closing button 11 is square, the shape of the first installation cavity 131 is a square structure adapted thereto, and at this time the shape of the opening button 12 is different from the closing button 11. For example, at this time the opening button 12 is circular, then the shape of the second installation cavity 132 is the other adapted circular structure. Therefore, the shapes of the first installation cavity 131 and the second installation cavity 132 are different, and during the installation process, if a wrong installation occurs, it will be impossible to assemble or a large gap will be generated after assembly, reminding the assembler of the wrong installation.

[0046] Specifically, the closing button 11, the opening button 12 and the housing 13 are connected in a snap-fit ​​manner. The snap-fit ​​connection makes installation more convenient. In addition, other connection methods can also be used.

[0047] Specifically, as attached Figure 2-8 As shown, the closing button 11 includes a first buckle portion 112, and the opening button 12 includes a second buckle portion, and the first buckle portion 112 has the same structure as the second buckle portion. It should be noted here that the housing 13 is provided with a slot that cooperates with the buckle portion, and the buckle portion and the slot cooperate to form a one-way blocking effect. For example, when the closing button 11 is pressed, the closing button 11 will move axially toward the inside of the housing 13, and the first buckle portion 112 will also move with it. However, when the force applied to the closing button 11 disappears, the elastic reset member 14 inside the housing 13 will drive the closing button 11 to move toward the front side of the housing 13. Due to the action of the first buckle portion 112, the closing button 11 will not be separated from the housing 13.

[0048] Specifically, as attached Figure 2-8 As shown, the closing button 11 includes a first buckle portion 112, and the opening button 12 includes a second buckle portion 122, and the first buckle portion 112 and the second buckle portion 122 have different structures. The different structures here specifically refer to that the sizes of the first buckle portion 112 and the second buckle portion 122 are different, and the slot 133 provided on the housing 13 is also provided accordingly, so the large-sized buckle cannot cooperate with the small-sized slot 133, forming an anti-foolproof assembly effect. In addition, the positions of the first buckle portion 112 and the second buckle portion 122 can also be different, that is, the first buckle portion 112 is closer to the center position of the closing button 11, and the second buckle portion 122 is far from the center position of the opening button 12. The number of the first buckle portion 112 and the second buckle portion 122 can also be different, for example, the number of the first buckle portion 112 is two, and the number of the second buckle portion 122 is one. The buckle portion cooperates with the pressing portion to achieve a double anti-foolproof effect.

[0049] Specifically, as attached Figure 2-8As shown, the closing button 11 includes a first foolproof protrusion 113, the opening button 12 includes a second foolproof protrusion 123, the housing 13 is provided with a first foolproof groove 134 and a second foolproof groove 135, the first foolproof protrusion 113 cooperates with the first foolproof groove 134, the second foolproof protrusion 123 cooperates with the second foolproof groove 135, the first foolproof protrusion 113 and the second foolproof protrusion 123 have different structures, and the structures of the first foolproof protrusion 113 and the second foolproof protrusion 123 here can be different in shape, for example, one is a fan-shaped structure and the other is a long strip structure. Or, the first foolproof protrusion 113 and the second foolproof protrusion 123 are in different positions. The first foolproof protrusion 113 is closer to the center position of the closing button 11, and the second foolproof protrusion 123 is far away from the center position of the opening button 12. In addition, the number of the first foolproof protrusion 113 and the second foolproof protrusion 123 is different, which can also form a foolproof effect. The setting of the fool-proof protrusion further achieves the fool-proof effect. Those skilled in the art can choose one or two or more combinations to improve the fool-proof effect. For example, one or two or more combinations of the pressing part, the buckle part, and the fool-proof protrusion (the first pressing part 111, the first buckle part 112, and the first fool-proof protrusion 113 on the closing button; or the second pressing part 121, the second buckle part 122, and the second fool-proof protrusion 123 on the opening button) form a fool-proof effect and improve the accuracy of assembly. In addition, the fool-proof protrusion can also be the driving part of the button, which plays a role in cooperating with the operating mechanism inside the shell during the pressing process, or the driving part can be set separately on the button.

[0050] Specifically, in addition to this, the elastic return member 14 can also be sleeved on the anti-foolproof protrusion. For example, the elastic return member 14 is sleeved on the first anti-foolproof protrusion 113, so that one end of the elastic return member 14 is against the first pressing portion 111, and the other end of the elastic return member 14 is against the first mounting cavity 131.

[0051] Specifically, as attached Figure 1-2 As shown, the closing button 11 is provided with a first pressing groove 114, and the opening button 12 is provided with a second pressing groove 124. The first pressing groove 114 is located on the front side of the first pressing portion 111, and the second pressing groove 124 is located on the front side of the second pressing portion 121.

[0052] Specifically, the closing button 11 and the opening button 12 can also be distinguished by color and text.

[0053] Specifically, the housing 13 is the housing 13 of a frame-type circuit breaker; or, the housing 13 is the housing 13 of a dual power switch with electric energy storage; or, the housing 13 is the housing 13 of a molded case circuit breaker with electric operation; or, the housing 13 is the housing 13 of a load disconnect switch; or, the housing 13 is the housing 13 of a medium-voltage circuit breaker. This button structure can be applied to different electrical product housings 13. In this embodiment, only the housing 13 of a frame-type circuit breaker is used as an example for description, and the structures of the other housings 13 are similar structures, and the only difference is the size and position.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
