The guide ribs are slidably disposed in the guide grooves or guide holes.

[0012] In one possible implementation, the moving iron core support is disposed within the control module housing, which includes a base plate, a frame, and a first mounting bracket. The frame is located between the base plate and the first mounting bracket, with the base plate covering the frame on the side away from the contact support. The surface area of ​​the first mounting bracket is larger than the cross-sectional area of ​​the frame. The limiting rib is disposed on the first mounting bracket, and an elastic element connects the first mounting bracket and the moving iron core support.

[0013] In one possible implementation, the moving iron core has a "T"-shaped structure, including an integrally formed induction part and a second mounting part. The induction part is inductively coupled with the coil. The moving iron core support is provided with a second mounting groove. The second mounting part is installed in the second mounting groove.

Detailed Implementation

[0030] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0031] The contactor includes a contact system and an electromagnetic system. The contact system includes a stationary contact, a moving contact, and a contact support. The electromagnetic system includes a stationary iron core, a moving iron core 21, and a coil for driving the moving iron core 21 to move. The stationary iron core and the moving iron core 21 are arranged opposite to each other, and the coil is located between the stationary iron core and the moving iron core 21. At least one moving contact is disposed on the contact support, and each moving contact corresponds to a stationary contact. The contacting or separating of the moving contact and the stationary contact can connect or disconnect the circuit. Both ends of the moving contact or the stationary contact are connected to contact terminals. The two contact terminals serve as the input terminal and the output terminal, respectively, for connecting the power supply and the load. The contactor also has a coil terminal electrically connected to the coil of the electromagnetic system. The coil terminal is used to connect to the control power supply to power or de-power the coil, thereby driving the moving iron core 21 to move. This is prior art in the art.

[0032] like Figures 1-4 As shown, this application provides a contactor including a control module. The control module includes a control module housing 1, in which a stationary iron core and a coil are disposed. The coil is disposed between a moving iron core 21 and the stationary iron core. The moving iron core 21 is disposed on a moving iron core support 22, which is slidably connected to the control module housing 1. The moving iron core support 22 is provided with a first linkage part, which is used for a detachable connection with a contact support.

[0033] This application arranges the stationary iron core and coil inside the control module housing 1. The coil is arranged between the moving iron core 21 and the stationary iron core. The moving iron core 21 is arranged on the moving iron core support 22. The moving iron core support 22 is slidably connected to the control module housing 1, so that the electromagnetic system of the contactor forms an independent control module. The modular design reduces the number of parts and facilitates management. The moving iron core support 22 is provided with a first linkage part, which is detachably connected to the contact support. If the control module or contact system is damaged, disassembly and replacement are convenient, saving costs and improving installation efficiency.

[0034] like Figure 1 As shown, for ease of understanding of the technical solution of this application, the thickness direction of the control module is defined as the first direction D1, the width direction of the control module is defined as the second direction D2, and the height direction of the control module is defined as the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The moving iron core support 22 and the control module housing 1 are detachably installed along the first direction D1.

[0035] Preferably, the moving iron core support 22 is provided with at least one first locking part, and the control module housing 1 is provided with at least one second locking part. The moving iron core support 22 and the control module housing 1 are slidably installed through the first locking part and the second locking part.

[0036] Furthermore, such as Figures 1-4As shown, the moving iron core support 22 is assembled along the thickness direction of the control module. The first locking part is at least one limiting rib 222 extending from the side of the moving iron core support 22. The second locking part is at least one limiting plate 12 extending from the control module housing 1 toward the moving iron core support 22. The limiting plate 12 has a limiting hole or a limiting groove. The limiting rib 222 can extend into the limiting hole or the limiting groove and press against the limiting plate 12. The limiting plate 12 can have a certain elasticity and can undergo plastic deformation to avoid the limiting rib 222. After the limiting rib 222 is installed in the limiting hole or limiting groove, the limiting plate 12 resets, thereby locking the limiting rib 222 onto the limiting plate 12. At least one elastic element 3 is provided between the moving iron core support 22 and the control module housing 1. The elastic element 3 drives the moving iron core 21 away from the stationary iron core, causing the limiting rib 222 to abut against the side wall of the limiting hole or limiting groove. Thus, the moving iron core support 22 can be fixedly installed on the control module housing 1 by the elastic element 3. When the moving iron core support 22 slides, it compresses the elastic element 3. The limiting hole or limiting groove has a movable space, allowing the moving iron core support 22 to approach the control module housing 1 when the coil is energized, and the elastic element 3 to drive the moving iron core support 22 away from the control module housing 1 when the coil is de-energized. The elastic element 3 can be, but is not limited to, a compression spring, torsion spring, or other elastic element.

[0039] Furthermore, the first connecting shaft includes two third locking parts at both ends. The two third locking parts protrude from the two groove walls of the first groove, and the third locking member is installed on the third locking part to limit the position corresponding to the first boss and the first groove.

[0040] Furthermore, the third locking part can be a thread, and the third locking element can be a nut or a torsion member; or the third locking part can be a third slot, and the third locking element is a torsion member.

[0041] Preferably, in one embodiment, such as Figure 5 and Figure 6 As shown, the first linkage part includes a sliding groove 25, which extends along the second direction D2 towards both sides of the control module. The contact support includes at least one mounting platform, and at least one mounting platform is installed within the sliding groove 25.

[0042] Furthermore, the mounting platform includes two first retaining walls on both sides opposite to the third direction D3, and the first retaining wall forms the first retaining groove 261 between the two first retaining walls.

[0043] Furthermore, at least one first elastic element 262 is provided on the side of the mounting platform facing the sliding groove 25. After the mounting platform is installed in the sliding groove 25, the first elastic element 262 is located between the mounting platform and the first linkage part. The elasticity of the first elastic element 262 will press and fix the contact support and the first linkage part.

[0044] Furthermore, such as Figure 5 and Figure 6 As shown, the mounting platform has two first elastic members 262 on the side facing the sliding groove 25, and a guide groove 263 is provided between the two first elastic members 262. The guide groove 263 and the two first elastic members 262 are parallel to each other. The sliding groove 25 of the first linkage part is provided with a guide protrusion 252 that cooperates with the guide groove 263. The guide protrusion 252 extends along the second direction D2 towards both sides of the control module.

[0045] Furthermore, such as Figure 6 As shown, the first elastic element 262 is a metal sheet, and the two ends of the first elastic element 262 are bent towards each other to form a second barb. The mounting platform is provided with a second slot that cooperates with the second barb. The first elastic element 262 is mounted on the mounting platform through the second barb. The first elastic element 262 is a flat plate structure. The mounting platform has two grooves facing each other on the side facing the sliding groove 25. After the first elastic element 262 is bent, its two ends are inserted into the two grooves.

[0046] Preferred, such as Figure 2As shown, the moving iron core support 22 is disposed inside the control module housing 1. The control module housing 1 includes a base plate 14, a frame 15, and a first mounting bracket 17. The frame 15 is located between the base plate 14 and the first mounting bracket 17. The base plate 14 covers the frame 15, and the base plate 14 covers the side away from the contact support for easy maintenance and installation. The frame 15 and the first mounting bracket 17 are integrally formed. The surface area of ​​the first mounting bracket 17 is larger than the cross-sectional area of ​​the frame 15. The limiting rib 222 is provided. On the first mounting bracket 17, the elastic element 3 is connected between the first mounting bracket 17 and the moving iron core support 22. Compared with the existing scheme where the elastic element 3 is set between the moving iron core 21 and the stationary iron core and is fitted on the coil frame, this embodiment sets the elastic element 3 between the first mounting bracket 17 and the moving iron core support 22, which serves to install and fix the moving iron core support 22 and drive the moving iron core 21 and the moving iron core support 22 to reset. Moreover, the elastic element 3 is located on the outside of the control module housing 1, which is convenient for installation and suitable for automated assembly.

[0047] Preferably, the moving iron core support 22 further includes at least one guide rib 221 that is perpendicularly connected to the first linkage part.

The guide ribs 221 are integrally formed with the moving iron core support 22. The guide ribs 221 extend towards the control module housing 1 along the first direction D1 and into the guide grooves 11. The control module housing 1 and the moving iron core support 22 can be mutually limited in the second direction D2 and the third direction D3. The guide ribs 221 slide back and forth in the guide grooves 11, which can play a guiding role. In this application, the moving iron core support 22 and the guide ribs 221 are integrally formed. The moving iron core 21 is mounted on the moving iron core support 22, which reduces the number of parts, makes installation and disassembly convenient, and facilitates maintenance and replacement.

[0049] Preferred, such as Figures 2-4 As shown, the guide rib 221 is plate-shaped. After the guide rib 221 is installed with the guide groove 11, the installation effect is stable and the stability of the guide rib 221 sliding in the guide groove 11 can also be improved.

[0050] Furthermore, the moving iron core 21 is located between the two guide ribs 221.

[0051] Preferred, such as Figure 3As shown, in this embodiment, the elastic element 3 is a compression spring. The moving iron core 21 and the elastic element 3 can cause the moving iron core support 22 to reciprocate in the first direction D1. When the coil is energized, the moving iron core 21 drives the moving iron core support 22 to slide towards the stationary iron core, and the moving iron core 21 can contact the stationary iron core; when the coil is de-energized, the elastic element 3 drives the moving iron core support 22 to slide away from the stationary iron core, so that the moving iron core 21 and the stationary iron core separate.

[0052] Furthermore, the moving iron core support member 22 is provided with at least one first fixing part, the control module housing 1 is provided with at least one second fixing part 23, and the two ends of the elastic member 3 are installed on the first fixing part and the second fixing part 23.

[0053] Furthermore, such as Figures 2-4 As shown, the moving iron core support 22 is provided with four first fixing parts at intervals, and the control module housing 1 is provided with four second fixing parts 23 at intervals. Preferably, as shown... Figure 3 and Figure 4 As shown, the four first fixing parts on the moving iron core support 22 extend to one side along the third direction D3, forming a clearance area between the two first fixing parts in the second direction D2. This saves internal space in the contactor, reduces the contactor's size, and makes the contactor more aesthetically pleasing. In this embodiment, the limiting rib 222 is provided on the first fixing part and extends to one side along the second direction D2.

[0054] Furthermore, such as Figure 4 As shown, the first fixing part includes a second groove or a second protrusion protruding in the direction of the control module housing 1.

Preferably, both the first fixing part and the second fixing part 23 include the second groove and the second protrusion. The second protrusion is provided in the second groove. The two ends of the elastic member 3 extend into the second groove and are respectively locked on the second protrusion, which can make the elastic member 3 more firmly fixed.

[0055] Preferred, such as Figure 4 As shown, the moving iron core 21 has a "T" shaped structure, including an integrally formed sensing part 211 and a second mounting part 212. In this embodiment, the sensing part 211 is located in the plane of the first direction D1 and the second direction D2, and the second mounting part 212 is located in the plane of the second direction D2 and the third direction D3. The sensing part 211 is inductively coupled with the coil. The moving iron core support 22 is provided with a second mounting groove, and the second mounting part 212 is installed in the second mounting groove.

[0056] Furthermore, such as Figure 2 and Figure 4 As shown, the second mounting part 212 is provided with two first through holes 213 spaced apart. The first through holes 213 are through along the second direction D2 and the two first through holes 213 are parallel. Second through holes are opened on both sides of the second mounting groove. The second through holes are through along the second direction D2. The second mounting part 212 is installed in the second mounting groove. The first through holes correspond to the second through holes. The control module also includes two mounting shafts 214. Each mounting shaft 214 passes through a first through hole 213 and the second through holes on both sides to install and fix the moving iron core 21 and the moving iron core support 22, making the fixation more secure.

[0057] Furthermore, such as Figure 2 and Figure 4 As shown, the diameter of the second through hole is larger than the diameter of the first through hole 213. The mounting shaft 214 includes a through shaft 215 and locking members 216 disposed at both ends of the through shaft 215. The diameter of the locking member 216 is larger than the diameter of the through shaft 215. The through shaft 215 passes through the first through hole 213 and the second through holes at both ends. The locking member 216 is installed in the second through hole. The locking member 216 and the through shaft 215 are locked together, thereby realizing the fixed installation of the moving iron core 21 and the moving iron core support member 22.

[0061] Furthermore, in other feasible embodiments, the first locking part and the second locking part are snap-fit ​​slidingly installed. The second locking part includes the limiting plate 12, and the side of the limiting plate 12 facing the moving iron core support 22 protrudes to form a hook. The first locking part is a slot opened on the side of the moving iron core support 22. The hook and the slot correspond. When the control module housing 1 and the moving iron core support 22 are installed, the side of the moving iron core support 22 abuts against the hook, causing the limiting plate 12 to plastically deform. After the hook extends into the slot, the limiting plate 12 resets. The slot has sliding space, and the hook can slide in the slot, thereby realizing the snap-fit ​​sliding installation of the first locking part and the second locking part.

[0062] Furthermore, such as Figures 2-4 As shown, four elastic elements 3 are spaced apart between the first mounting bracket 17 of the control module housing 1 and the moving iron core support 22. The four elastic elements 3 are arranged in a rectangular pattern. The control module housing 1 has four second grooves or second protrusions, and the moving iron core support 22 has four second grooves or second protrusions. One end of each elastic element 3 is connected to a second groove or second protrusion on the control module housing 1, and the other end is connected to a second groove or second protrusion on the moving iron core support 22. In this embodiment, four elastic elements 3 are spaced apart between the moving iron core support 22 and the control module housing 1. The four elastic elements 3 are located at the four corners of the rectangle, which can make the repulsive force between the moving iron core support 22 and the control module housing 1 more balanced.

[0063] Preferred, such as Figure 2 As shown, an elastic buffer 4 is provided between the moving iron core support 22 and the moving iron core 21. When the coil is energized, the moving iron core 21 drives the moving iron core support 22 to close with the control module housing 1; or when the coil is de-energized, the elastic element 3 drives the moving iron core support 22 away from the control module housing 1. An impact force is generated between the moving iron core 21 and the moving iron core support 22. The buffer 4 can buffer and reduce shock, thereby improving the product's service life.

[0064] Furthermore, the buffer 4 is made of an elastic material. For example, the material of the buffer 4 can be rubber or silicone, or the buffer 4 can also be a compression spring or spring, etc.

[0065] Furthermore, such as Figure 2 As shown, the buffer 4 includes an integrally formed extrusion part 41 and a first mounting part 42. The surface area of ​​the extrusion part 41 is larger than the surface area of ​​the first mounting part 42. After the moving iron core support 22 and the moving iron core 21 are installed, the extrusion part 41 of the buffer 4 is located between the second mounting part 212 of the moving iron core 21 and the moving iron core support 22.

[0066] Furthermore, this embodiment includes two buffer members 4. The moving iron core support member 22 is provided with two first mounting holes or first mounting grooves that are fixedly installed on the first mounting part 42 at intervals. The buffer members 4 are installed on the moving iron core support member 22 through the first mounting part 42.
