[0003] In the existing contactor, the moving iron core is limitedly installed on the supporting member by spring sheet, the spring sheet can provide elastic force, the spring sheet deforms when the static iron core attracts the moving iron core, and the spring sheet restores the deformation to quickly separate the moving iron core from the static iron core when the coil is de-energized.

[0004] However, this assembly form is prone to cause the moving iron core to separate from the supporting member under the condition of vibration or improper installation, the assembly stability is poor, and the normal use of the contactor is affected. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the present application is to provide a kind of contactor, can improve the assembly stability of moving iron core, to make the on-off performance of contactor remain stable.

[0006] The embodiment of the present application provides a kind of contactors, including moving iron core and supporting member, spring sheet is arranged on moving iron core.The supporting member is provided with installation sliding slot, first limit slot and second limit slot are oppositely arranged on the both sides of installation sliding slot, and support boss is arranged on the bottom wall of installation sliding slot.Moving iron core is installed in installation sliding slot and abuts the top of support boss, the first end of spring sheet is connected to first limit slot, and the second end of spring sheet is connected to second limit slot.Support boss supports moving iron core, so that the first end of spring sheet abuts the inner wall of first limit slot, and the second end of spring sheet abuts the inner wall of second limit slot.

[0007] By setting support boss on the bottom wall of installation sliding slot, the moving iron core can be supported after being installed in installation sliding slot, the first end of spring sheet can abut the upper side wall of first limit slot, and the second end of spring sheet can abut the upper side wall of second limit slot, so as to clamp the first end in first limit slot and clamp the second end in second limit slot by using support boss.

[0008] In this way, the possibility of spring sheet separating from first limit slot and second limit slot can be reduced, the assembly stability of spring sheet on supporting member can be effectively improved, and the assembly stability between moving iron core and supporting member can be improved, so as to reduce the risk of loosening or slipping under the condition of vibration or inverted installation.

[0009] In some examples, the top of the support boss comprises a first inclined surface, a support surface and a second inclined surface connected in sequence, the intersection line of the first inclined surface and the support surface is parallel to the intersection line of the second inclined surface and the support surface, the arrangement direction of the first inclined surface, the support surface and the second inclined surface is parallel to the groove wall of the mounting sliding groove, and the bottom end of the first inclined surface and the second inclined surface is away from the support surface and close to the bottom wall of the mounting sliding groove.

[0010] The support surface is arranged to directly abut the bottom surface of the moving iron core and provide support, and the first inclined surface and the second inclined surface are arranged to form symmetrical active spaces on both sides of the support boss relative to the support surface, so that the moving iron core has a swing adjustment and a buffer space when it is separated from the static iron core and contacts the support boss, reducing the possibility of collision between the moving iron core and the support boss, and facilitating the stable structure of the moving iron core and the support, thereby reducing the influence on the assembly stability therebetween.

[0011] In some examples, two support bosses are arranged in parallel and spaced apart in the mounting sliding groove, one of the two support bosses is close to the first limiting groove, and the other of the two support bosses is close to the second limiting groove.

[0012] The two support bosses are arranged in a spaced apart manner, which can simultaneously support the moving iron core from two positions, facilitating stable support of the moving iron core in the mounting sliding groove. Moreover, the two support bosses correspond to the first limiting groove and the second limiting groove respectively, which can correspondingly improve the connection stability of the first end of the spring sheet in the first limiting groove and the connection stability of the second end of the spring sheet in the second limiting groove, so that the spring sheet is stably connected on the support, reducing the possibility of the moving iron core being separated due to the spring sheet being separated from the support.

[0017] In some examples, a plurality of limiting protrusions are arranged at intervals in the mounting sliding groove, and a plurality of assembly grooves are arranged in the mounting sliding groove, and the plurality of limiting protrusions and the plurality of assembly grooves are in one-to-one correspondence.

[0018] The plurality of limiting protrusions and the plurality of assembly grooves are in one-to-one correspondence, which can further improve the assembly stability of the moving iron core in the mounting sliding groove and effectively reduce the risk of the moving iron core being separated due to vibration or the moving iron core being installed upside down with the support.

[0019] In some examples, the support further comprises a first ear and a second ear, and the first ear and the second ear are arranged opposite to each other on two sides of the mounting sliding groove. The first limiting groove is arranged in the first ear, and the second limiting groove is arranged in the second ear.

[0020] The first ear is provided with a first notch, and the first notch is in communication with the first limiting groove. The first end of the spring sheet can enter the first limiting groove along the first notch. The second ear is provided with a second notch, and the second notch is in communication with the second limiting groove. The second end of the spring sheet can enter the second limiting groove along the second notch.

[0021] The arrangement of the first ear and the second ear can cooperate with the two opposite groove walls in the mounting sliding groove to jointly limit the installation position of the moving iron core, and at the same time, the structure is simple and convenient for opening the first limiting groove and the second limiting groove. In addition, the arrangement of the first notch can serve as a channel for the first end of the spring sheet to enter the first limiting groove, and the arrangement of the second notch can serve as a channel for the second end of the spring sheet to enter the second limiting groove. This facilitates the smooth installation of the spring sheet between the first limiting groove and the second limiting groove when the moving iron core is slidably installed into the mounting sliding groove, and is conducive to simplifying the installation method.

[0022] In some examples, the first end of the spring sheet is provided with a first bending portion, and the side of the first limiting groove opposite to the bottom surface of the mounting sliding groove is provided with a first abutting portion. The first bending portion abuts against the first abutting portion. The second end of the spring sheet is provided with a second bending portion, and the side of the second limiting groove opposite to the bottom surface of the mounting sliding groove is provided with a second abutting portion. The second bending portion abuts against the second abutting portion.

[0023] Through the cooperation of the first bending portion and the first abutting portion, the contact area of the first end of the spring sheet and the upper side wall of the first limiting groove can be increased, and the cooperation stability of the spring sheet and the first limiting groove can be improved. Similarly, through the cooperation of the second bending portion and the second abutting portion, the contact area of the second end of the spring sheet and the upper side wall of the second limiting groove can be increased, and the cooperation stability of the spring sheet and the second limiting groove can be improved.

[0024] In some examples, the first notch is provided with a first guide surface, and the first guide surface is connected with the first abutting portion. The second notch is provided with a second guide surface, and the second guide surface is connected with the second abutting portion.

[0025] The first guide surface facilitates the first bending part to slide into the first limiting groove from the first gap, and the second guide surface facilitates the second bending part to slide into the second limiting groove from the second gap, thereby facilitating the installation of the spring sheet.

[0026] In some examples, the contactor further includes a static core disposed on a side of the moving core away from the support.

DETAILED DESCRIPTION

[0041] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0043] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

In addition, the terms “first”, “second” and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0045] In the description of the present application, it should also be noted that unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] In the existing contactor, the moving iron core is installed on the support by spring sheet, when the static iron core adsorbs the moving iron core, the moving iron core approaches the static iron core, the support is fixed, and the spring sheet deforms. When the adsorption of the static iron core to the moving iron core disappears, the spring sheet restores the deformation to make the moving iron core away from the static iron core and close to the support.

[0047] However, due to the unstable assembly structure between the existing moving iron core and the support, the moving iron core and the support are prone to loosen or separate under the condition of vibration or inverted installation of the moving iron core and the support, resulting in that the contactor cannot be used normally.

[0048] Based on this, the embodiment of the present application provides a contactor which can improve the assembly stability of the moving iron core to keep the on-off performance of the contactor stable.

[0049] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings.

[0050] Please refer to Figures 1 to 4 The embodiment provides a contactor, which comprises a moving iron core 1 and a support 2, and a spring sheet 3 is arranged on the moving iron core 1. The support 2 is provided with a mounting sliding groove 21, first and second limiting grooves 22 and 23 are oppositely arranged on the two sides of the mounting sliding groove 21, and a supporting boss 24 is arranged on the bottom wall of the mounting sliding groove 21. The moving iron core 1 is installed in the mounting sliding groove 21 and abuts against the top of the supporting boss 24, the first end 31 of the spring sheet 3 is connected to the first limiting groove 22, and the second end 32 of the spring sheet 3 is connected to the second limiting groove 23. The supporting boss 24 supports the moving iron core 1, so that the first end 31 of the spring sheet 3 abuts against the inner wall of the first limiting groove 22, and the second end 32 of the spring sheet 3 abuts against the inner wall of the second limiting groove 23.

[0051] By setting the supporting boss 24 on the bottom wall of the installation sliding groove 21, the dynamic iron core 1 can be supported after being installed to the installation sliding groove 21, and after the dynamic iron core 1 is supported and lifted relative to the bottom wall of the installation sliding groove 21, the first end 31 of the spring sheet 3 can abut against the upper side wall of the first limiting groove 22, and the second end 32 of the spring sheet 3 can abut against the upper side wall of the second limiting groove 23, so that the supporting boss 24 is used to clamp the first end 31 in the first limiting groove 22 and clamp the second end 32 in the second limiting groove 23.

[0052] In this way, the possibility of the spring sheet 3 being separated from the first limiting groove 22 and the second limiting groove 23 can be reduced, the assembly stability of the spring sheet 3 on the support 2 can be effectively improved, and the assembly stability between the dynamic iron core 1 and the support 2 can be improved, and the risk of loosening or slipping in the case of vibration or inverted installation can be reduced.

[0053] Specifically, referring to Figure 4 and Figure 5 , the dynamic iron core 1 is provided with a through hole 11, the through hole 11 communicates the two opposite side surfaces of the dynamic iron core 1, the axis of the through hole 11 is parallel to the bottom surface of the dynamic iron core 1, and the position of the through hole 11 on the side surface of the dynamic iron core 1 is close to the bottom surface of the dynamic iron core 1. The spring sheet 3 is arranged in the through hole 11, and the two ends of the spring sheet 3 correspond to the two openings of the through hole 11.

[0054] Referring to Figure 1 and Figure 4 , the support 2 is provided with an installation sliding groove 21, and the dynamic iron core 1 can be slidably installed in the installation sliding groove 21, the installation sliding groove 21 can limit the installation position of the dynamic iron core 1, and the two opposite groove walls in the installation sliding groove 21 can limit the sliding installation direction of the dynamic iron core 1.

[0055] In combination with Figures 6 to 9 , the two sides of the installation sliding groove 21 are provided with a first limiting groove 22 and a second limiting groove 23, the first limiting groove 22 and the second limiting groove 23 can be arranged on the two groove walls of the installation sliding groove 21, or can be arranged on the extension parts of the two groove walls, such as the wall surface corresponding to the groove wall arranged on the support 2. The dynamic iron core 1 is in the installation sliding groove 21, at this time the through hole 11 communicates the first limiting groove 22 and the second limiting groove 23, the first end 31 of the spring sheet 3 is correspondingly connected to the first limiting groove 22, and the second end 32 of the spring sheet 3 is correspondingly connected to the second limiting groove 23.

[0056] Referring to Figure 2 and Figure 3The bottom wall of the installation sliding groove 21 is provided with a support boss 24. After the moving iron core 1 is installed to the installation sliding groove 21, the bottom surface of the moving iron core 1 is close to the bottom wall of the installation sliding groove 21, and the bottom surface of the moving iron core 1 is abutted to the top of the support boss 24. The support boss 24 raises the installation height of the moving iron core 1 in the installation sliding groove 21, and the heights of the first limiting groove 22 and the second limiting groove 23 are fixed, so that the first end 31 of the spring sheet 3 is pressed against the upper side wall of the first limiting groove 22, and the second end 32 of the spring sheet 3 is pressed against the upper side wall of the second limiting groove 23, to realize the fixing effect of the spring sheet 3, reduce the possibility of the spring sheet 3 from the first limiting groove 22 and the second limiting groove 23, and further reduce the possibility of the moving iron core 1 from the installation sliding groove 21. And this kind of setting form has the characteristics of simple structure and convenient assembly.

[0057] With reference to Figure 6 and Figure 7 In some examples, the top of the support boss 24 includes a first inclined surface 241, a support surface 242 and a second inclined surface 243 connected in sequence, the intersection line of the first inclined surface 241 and the support surface 242 is parallel to the intersection line of the second inclined surface 243 and the support surface 242, the arrangement direction of the first inclined surface 241, the support surface 242 and the second inclined surface 243 is parallel to the groove wall of the installation sliding groove 21, and the bottom end of the first inclined surface 241 and the second inclined surface 243 is away from the support surface 242 and close to the bottom wall of the installation sliding groove 21.

[0058] The support surface 242 is arranged to directly abut the bottom surface of the moving iron core 1 and provide support, and the first inclined surface 241 and the second inclined surface 243 are arranged to form symmetrical active spaces on both sides of the support surface 242 on the support boss 24, so that the moving iron core 1 can have swing adjustment and buffer space when it is separated from the static iron core and contacts the support boss 24, reducing the possibility of collision between the moving iron core 1 and the support boss 24, and facilitating the structure of the moving iron core 1 and the support 2 to remain stable, thereby reducing the influence on the assembly stability between them.

[0059] With reference to Figure 3 and Figure 4 The support boss 24 is arranged as a long strip-shaped boss, and the support boss 24 is arranged on the bottom wall of the installation sliding groove 21 along the length direction of the installation sliding groove 21, and is arranged along the length direction of the installation sliding groove 21, which is equivalent to being arranged along the side wall of the installation sliding groove 21.

[0060] The support surface 242 is arranged at the middle position of the top of the support boss 24, the first inclined surface 241 and the second inclined surface 243 are also arranged at the top of the support boss 24, and the first inclined surface 241 and the second inclined surface 243 are symmetrically arranged on both sides of the support surface 242.

[0061] With reference to Figure 7The first inclined surface 241 extends away from the support surface 242 from the position where it intersects with the support surface 242, while also approaching the bottom of the support boss 24. The second inclined surface 243 extends away from the support surface 242 from the position where it intersects with the support surface 242, while also approaching the bottom of the support boss 24.

[0062] When the moving iron core 1 separates from the stationary iron core, the moving iron core 1 rebounds into the mounting groove 21 under the action of the spring plate 3 and contacts the support boss 24. Since the moving iron core 1 may be tilted during the rebound process and cannot contact the support surface 242 in parallel, one end of the moving iron core 1 can first contact the first inclined surface 241 or the second inclined surface 243 and then contact the support surface 242 to adjust the angle and buffer, reduce the possibility of the moving iron core 1 in the tilted state colliding with the support boss 24, and thus reduce the risk of the moving iron core 1 falling off the mounting groove 21.

[0063] Reference Figures 6 to 9 In some examples, there are two support bosses 24, which are parallel and spaced apart in the mounting groove 21. One support boss 24 is close to the first limiting groove 22, and the other support boss 24 is close to the second limiting groove 23.

[0064] The two support bosses 24 are spaced apart, providing support to the moving iron core 1 from two positions simultaneously, which helps ensure stable support for the moving iron core 1 within the mounting groove 21. Furthermore, the two support bosses 24 correspond to the first limiting groove 22 and the second limiting groove 23, respectively. This improves the connection stability of the first end 31 of the spring sheet 3 in the first limiting groove 22 and the connection stability of the second end 32 of the spring sheet 3 in the second limiting groove 23, thereby maintaining a stable connection of the spring sheet 3 on the support member 2 and reducing the possibility of the moving iron core 1 detaching due to the spring sheet 3 disengaging from the support member 2.

[0065] Reference Figure 6 and Figure 8 The two support bosses 24 include a first support boss 24 and a second support boss 24, both of which are arranged along the length of the mounting groove 21. The first support boss 24 is arranged along the groove wall of the mounting groove 21 near the first limiting groove 22, and the second support boss 24 is arranged along the groove wall of the mounting groove 21 near the second limiting groove 23.

[0066] The first support boss 24 supports the moving iron core 1 on the side near the first end 31 of the spring plate 3. The direction of the support force provided by the first support boss 24 to the moving iron core 1 is opposite to the orientation of the upper side wall of the first limiting groove 22, so as to clamp the first end 31 of the spring plate 3 in the first limiting groove 22 and prevent the first end 31 of the spring plate 3 from coming out of the first limiting groove 22.

[0067] The second support boss 24 supports the moving iron core 1 on the side near the second end 32 of the spring plate 3. The direction of the support force provided by the support boss 24 to the moving iron core 1 is opposite to the orientation of the upper side wall of the second limiting groove 23, so as to clamp the second end 32 of the spring plate 3 in the second limiting groove 23 and prevent the second end 32 of the spring plate 3 from coming out of the second limiting groove 23.

[0068] Under the combined action of the first support boss 24 and the second support boss 24, the possibility of the spring plate 3 detaching from the support member 2 due to vibration or inversion of the support member 2 can be effectively reduced, thereby ensuring that the moving iron core 1 can maintain stable assembly with the support member 2 under the action of the spring plate 3.

[0069] Reference Figure 3 and Figure 10 In some examples, a limiting boss 25 is also provided in the mounting groove 21. The limiting boss 25 is set at an angle to the supporting boss 24. An assembly groove 12 is provided on the moving iron core 1. The limiting boss 25 is adapted to the assembly groove 12.

[0070] By cooperating with the limiting boss 25 and the assembly groove 12, the sliding of the moving iron core 1 in the mounting groove 21 after it is installed can be restricted, thereby further improving the assembly stability of the moving iron core 1 in the mounting groove 21.

[0071] The limiting boss 25 can be set on two opposite groove walls in the mounting groove 21, or on the bottom wall of the mounting groove 21. Correspondingly, the assembly groove 12 can be opened on the side of the moving iron core 1 where the through hole 11 is set, or on the bottom surface of the moving iron core 1 for abutting the supporting boss 24. The positioning function of the moving iron core 1 can be achieved by the limiting boss 25 and the assembly groove 12 being positioned and engaging with each other.

[0072] In this embodiment, the limiting boss 25 is disposed on the bottom wall of the mounting slide groove, and the limiting boss 25 and the supporting boss 24 are perpendicular to each other. The assembly groove 12 is formed on the bottom surface of the moving iron core 1. When the moving iron core 1 is assembled into the mounting slide groove 21, the assembly groove 12 on the moving iron core 1 engages with the limiting boss 25 to restrict the moving iron core 1. Of course, the included angle between the limiting boss 25 and the supporting boss 24 can also be 45° or 60°, etc., which can achieve the same technical effect as the vertical arrangement.

[0073] The shape and size of the limiting boss 25 match the shape and size of the assembly groove 12. For example, the limiting boss 25 can be set as a triangular frustum or a quadrangular frustum, and the assembly groove 12 can be set as a groove with a corresponding shape, both of which can achieve a stable limiting effect.

[0074] Reference Figure 3 and Figure 10In some examples, the limiting boss 25 is provided with a first chamfer 251 and the assembly groove 12 is provided with a second chamfer 121, and the first chamfer 251 and the second chamfer 121 are adapted to each other.

[0075] The first chamfer 251 is designed to facilitate the movement of the moving iron core 1 along the first chamfer 251 when the moving iron core 1 is manually separated from the support member 2, so as to unlock the limiting boss 25 and the assembly groove 12. At the same time, in conjunction with the second chamfer 121 set on the assembly groove 12, the assembly groove 12 and the limiting boss 25 can be quickly separated.

[0076] Reference Figure 3 and Figure 10 In this embodiment, the limiting boss 25 is configured as a truncated pyramid. The side of the limiting boss 25 facing the first notch 261 is configured as a right angle side, and the opposite side is configured as a first chamfer 251. Correspondingly, the assembly groove 12 also includes a right angle side, and the two right angle sides correspond to each other, as do the first chamfer 251 and the second chamfer 121.

[0077] This configuration utilizes the right-angled edge abutting against the right-angled edge to achieve a limiting effect. Specifically, when the moving iron core 1 slides along the mounting groove 21 from the opening direction of the first notch 261, the right-angled edge in the mounting groove 12 will abut against the right-angled edge of the limiting boss 25, thereby restricting the moving iron core 1 from continuing to move in that direction and reducing the possibility of wear between the first end 31 of the spring plate 3 and the side wall of the first limiting groove 22, and between the second end 32 of the spring plate 3 and the side wall of the second limiting groove 23.

[0078] Meanwhile, the first chamfer 251 and the second chamfer 121 abut against each other on the side away from the opening direction of the first notch 261, which can restrict the moving iron core 1 from sliding out of the mounting groove 21 from the opening direction of the first notch 261. Only when manually disassembled can the assembly groove 12 and the limiting boss 25 be easily separated through the first chamfer 251 and the second chamfer 121. This type of fit has the characteristics of simple and stable structure and convenient disassembly and assembly.

[0079] In some examples, multiple limiting bosses 25 are provided, and the multiple limiting bosses 25 are spaced apart in the mounting groove 21. Multiple assembly grooves 12 are provided, and the multiple assembly grooves 12 correspond one-to-one with the multiple limiting bosses 25.

[0080] Multiple limiting bosses 25 and multiple assembly slots 12 are connected one-to-one, which can further improve the assembly stability of the moving iron core 1 in the mounting slide 21 and effectively reduce the risk of the moving iron core 1 detaching due to vibration or inverted installation with the support 2.

[0081] Specifically, one, two, or more limiting bosses 25 can be provided, and two or more limiting bosses 25 can be arranged parallel and spaced apart on the bottom wall of the mounting groove 21. Correspondingly, one, two, or more assembly grooves 12 can also be provided, and two or more assembly grooves 12 can be arranged parallel and spaced apart on the bottom surface of the moving iron core 1. After the moving iron core 1 is slidably installed into the mounting groove 21, the assembly groove 12 and the limiting bosses 25 are engaged to achieve the fixed installation of the moving iron core 1.

[0082] Reference Figure 6 and Figure 8 In some examples, the support member 2 also includes a first ear 26 and a second ear 27, which are disposed opposite to each other on both sides of the mounting groove 21. A first limiting groove 22 is disposed on the first ear 26 and a second limiting groove 23 is disposed on the second ear 27.

[0083] The first ear portion 26 is provided with a first notch 261, which is connected to the first limiting groove 22. The first end 31 of the spring piece 3 can enter the first limiting groove 22 along the first notch 261. The second ear portion 27 is provided with a second notch 271, which is connected to the second limiting groove 23. The second end 32 of the spring piece 3 can enter the second limiting groove 23 along the second notch 271.

[0084] The first ear portion 26 and the second ear portion 27 are designed to work in conjunction with the two opposing groove walls in the mounting slide 21 to jointly restrict the installation position of the moving iron core 1. This design is simple and facilitates the creation of the first limiting groove 22 and the second limiting groove 23. Furthermore, the first notch 261 serves as a channel for the first end 31 of the spring plate 3 to enter the first limiting groove 22, and the second notch 271 serves as a channel for the second end 32 of the spring plate 3 to enter the second limiting groove 23. This allows the spring plate 3 to be smoothly installed between the first limiting groove 22 and the second limiting groove 23 when the moving iron core 1 is slidably installed into the mounting slide 21, simplifying the installation process.

[0085] Specifically, the first ear portion 26 and the second ear portion 27 are disposed opposite to each other on the support member 2. A first limiting groove 22 is formed on the side of the first ear portion 26 near the second ear portion 27, and a second limiting groove 23 is formed on the side of the second ear portion 27 near the first ear portion 26. A first notch 261 is formed on the first ear portion 26, and the axis of the first notch 261 is parallel to the sliding installation direction of the mounting groove 21. A second notch 271 is formed on the second ear portion 27, and the axis of the second notch 271 is also parallel to the sliding installation direction of the mounting groove 21.

[0086] When the moving iron core 1 is installed into the mounting groove 21 along the sliding installation direction, the first end 31 of the spring plate 3 can enter the first limiting groove 22 along the first notch 261, and the second end 32 can enter the second limiting groove 23 along the second notch 271. Under the action of the supporting boss 24, the first end 31 and the second end 32 are relatively fixed, and with the limiting action of the limiting boss 25, the spring plate 3 can be effectively prevented from sliding out from the first notch 261 and the second notch 271. Therefore, this setting has the characteristics of simple structure and stable assembly.

[0087] Combination Figure 5 , Figure 7 and Figure 9 In some examples, the first end 31 of the spring sheet 3 is provided with a first bent portion 311, and the first limiting groove 22 is provided with a first abutting portion 221 on the side opposite to the bottom surface of the mounting groove 21, and the first bent portion 311 abuts against the first abutting portion 221.

[0088] The second end 32 of the spring sheet 3 is provided with a second bending portion 321, and the second limiting groove 23 is provided with a second abutting portion 231 on the side opposite to the bottom surface of the mounting slide groove 21. The second bending portion 321 abuts against the second abutting portion 231.

[0089] The cooperation of the first bending portion 311 and the first abutting portion 221 increases the contact area between the first end 31 of the spring sheet 3 and the upper sidewall of the first limiting groove 22, thereby improving the stability of the fit between the spring sheet 3 and the first limiting groove 22. Similarly, the cooperation of the second bending portion 321 and the second abutting portion 231 increases the contact area between the second end 32 of the spring sheet 3 and the upper sidewall of the second limiting groove 23, thereby improving the stability of the fit between the spring sheet 3 and the second limiting groove 23.

[0090] A first bending portion 311 is provided at the first end 31 of the spring sheet 3, and a second bending portion 321 is provided at the second end 32. This can increase the elastic deformation range of the spring sheet 3, which is beneficial for the moving iron core 1 and the stationary iron core to attract each other, and also facilitates the moving iron core 1 and the stationary iron core to be reset into the mounting groove 21 after separation.

[0091] Reference Figure 7 and Figure 9 In some examples, a first guide surface 262 is provided on the first notch 261, and the first guide surface 262 is connected to the first abutment 221; a second guide surface 272 is provided on the second notch 271, and the second guide surface 272 is connected to the second abutment 231.

[0092] The first guide surface 262 facilitates the first bent part 311 to slide from the first notch 261 into the first limiting groove 22, and the second guide surface 272 facilitates the second bent part 321 to slide from the second notch 271 into the second limiting groove 23, thereby facilitating the installation of the spring sheet 3.

[0093] Specifically, the first guide surface 262 is disposed on the upper sidewall of the first notch 261, and is connected to the first abutment portion 221. The guiding direction of the first guide surface 262 is from the opening direction of the first notch 261 toward the first limiting groove 22, so as to facilitate the smooth entry of the first bent portion 311 into the first limiting groove 22. The second guide surface 272 is disposed on the upper sidewall of the second notch 271, and is connected to the second abutment portion 231. The guiding direction of the second guide surface 272 is from the opening direction of the second notch 271 toward the second limiting groove 23, so as to facilitate the smooth entry of the second bent portion 321 into the second limiting groove 23, which is beneficial to the assembly of the moving iron core 1 and the support member 2.

[0094] In some examples, the contactor also includes a stationary iron core, which is disposed on the side of the moving iron core 1 away from the support 2.

[0095] The stationary iron core is set on the side of the moving iron core 1 away from the support member 2, so that the moving iron core 1 always moves in a direction perpendicular to the bottom wall of the mounting groove 21 as it approaches or moves away from the stationary iron core, thus preventing the moving iron core 1 from detaching from the mounting groove 21 along the sliding mounting direction during the movement.

[0096] The moving iron core 1 and the stationary iron core work together to switch the contactor on and off. When the moving iron core 1 is subjected to the electromagnetic force of the stationary iron core, it moves towards the stationary iron core, i.e., away from the support member 2, based on the mounting groove 21 of the support member 2. When the moving iron core 1 is disconnected from the stationary iron core, it moves away from the stationary iron core, i.e., towards the support member 2. The direction of movement during the above-mentioned process is always perpendicular to the bottom wall of the mounting groove 21, i.e., perpendicular to the sliding installation direction of the moving iron core 1 into the mounting groove 21. This reduces the risk of the moving iron core 1 detaching from the support member 2 during movement.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
