Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a reversible contactor. Background Art

[0002] In the field of modern electrical engineering and automation technology, the setting of reversing contactors is a key component to ensure the safe operation of motors or other electrical equipment.

[0003] This contactor configuration usually includes two contactors of the same specification, which are combined by a precise mechanical interlocking mechanism and an electrical interlocking mechanism. Such a configuration can ensure that the two contactors will not close at the same time under the command triggered by mechanical vibration or operating error. In the existing technology, the mechanical interlocking mechanism is usually configured as a modular accessory that can be installed between the two contactors as needed.

[0004] However, the disadvantage of this arrangement is that the mechanical interlocking mechanism will cause the overall volume of the reversible contactor to increase, especially in small-capacity contactors, where this problem is more prominent. Utility Model Content

[0005] The present application provides a reversible contactor, which can make the structure of the reversible contactor more compact, save the occupied space of the entire reversible contactor, and improve space utilization.

[0006] The present application provides a reversible contactor, the reversible contactor comprising:

[0007] Two contactor units, each of which comprises a housing component, and two opposite sides of the housing component are respectively provided with assembly grooves.

[0008] At least one clamping member is used to connect the two contactor units. When the two contactor units are connected to each other, the assembly grooves on the two contactor units are butted against each other to form an assembly cavity.

[0009] A mechanical interlock is installed in the assembly cavity, and the size of the mechanical interlock is smaller than or equal to the size of the assembly cavity, so that the mechanical interlock is completely located in the assembly cavity.

[0010] The present application proposes a reversible contactor, the core goal of which is to optimize the structural layout to achieve more efficient space saving. Through this arrangement, the overall volume of the reversible contactor will be effectively reduced, thereby achieving higher space utilization in a limited space, which is particularly important for modern electronic devices that pursue high-density installation.

[0011] Specifically, the reversible contactor may include two contactor units, at least one clamping member, and a set of mechanical interlocks. The two contactor units form the basis of the reversible contactor, and each unit includes a housing assembly. The two opposite sides of the housing assembly may be provided with assembly grooves, respectively, and these assembly grooves may provide clearance spaces for the close arrangement of the contactor units, and these clearance spaces may be used for assembling the mechanical interlocks.

[0012] The clamping piece in the present application has the function of connecting two contactor units. Compared with the method of connecting the contactor unit to the cabinet or guide rail in the electric cabinet in the prior art, the connection stability is better, and the reversible contactor is no longer a simple splicing. The entire reversible contactor can be formed into a relative whole through the clamping piece.

[0013] When two contactor units are connected to each other, the assembly grooves of the two contactor units can be precisely docked to form a common assembly cavity. This setting not only enhances the structural stability of the contactor, but also facilitates subsequent assembly and maintenance.

[0014] The entire mechanical interlock can be completely installed in the assembly cavity. Specifically, the size of the mechanical interlock can be set to be less than or equal to the size of the assembly cavity, ensuring that the mechanical interlock can be completely accommodated in the assembly cavity. Such a setting not only ensures the safety of the contactor during operation, but also saves the installation space of the mechanical interlock, making the entire reversible contactor more compact and occupying less space overall.

[0015] In some examples, the housing assembly includes a base and a shell, and the base is fixedly connected to or integrally provided with the shell.

[0016] The base is provided with a first clamping structure, the shell is provided with a second clamping structure, and the clamping member includes a first clamping member connected to the base and a second clamping member connected to the shell.

[0017] When the two contactor units are connected to each other, the first clamping member is simultaneously clamped to the corresponding first clamping structures on the two bases, and the second clamping member is simultaneously clamped to the corresponding second clamping structures on the two shells.

[0018] The above-mentioned housing assembly of the present application may include a base and a shell, and these two parts may be combined by a fixed connection or an integrated setting; the main function of the base is to support and install various functional components in the contactor unit, while the shell is responsible for protecting these functional components.

[0019] A first clamping structure is provided on the base, and a second clamping structure is provided on the shell, and the two clamping structures are connected by a first clamping component and a second clamping component respectively; when two contactor units need to be connected to each other, the first clamping component will be simultaneously clamped on the corresponding first clamping structures on the two bases, and the second clamping component will also be simultaneously clamped on the corresponding second clamping structures on the two shells.

[0020] The first clamping structure and the first clamping member are used together to effectively connect the bases of the two contactor units, and the second clamping structure and the second clamping member are used together to connect the shells of the two contactor units. Such a double connection structure makes the entire connection more stable and reliable. In addition, the base and the shell in each contactor unit are also connected in some way. Combined with the above double connection, the stability of the entire reversible contactor is significantly improved.

[0021] In some examples, at least two first clamping members are provided, at least two first clamping members are located at different positions of the reversible contactor, and each first clamping member is simultaneously clamped to two first clamping structures located on the same side of the two bases; and / or,

[0022] At least two second clamping members are provided, and at least two second clamping members are located at different positions of the reversible contactor. Each second clamping member is simultaneously clamped to two second clamping structures located at the same side in the two housings.

[0023] In the above structure, at least two first clamping parts can realize multi-point connection between the two bases, thereby further improving the connection stability between the two bases. The first clamping part can be connected at the junction of the two bases, and two first clamping parts can be set as needed. The two first clamping parts can be respectively set on different sides of the reversible contactor, specifically on the opposite sides of the reversible contactor, and the first clamping parts can be respectively set on the adjacent two sides of the reversible contactor as needed. The same side of the reversible contactor can also be set with two or more first clamping parts.

[0024] In contrast, at least two second clips in the above structure can realize multi-point connection between the two shells, thereby further improving the connection stability between the two shells. The second clip can be connected at the junction of the two shells, and two second clips can be set as needed. The two second clips can be set on different sides of the reversible contactor, specifically on the opposite sides of the reversible contactor, and the second clips can be set on the adjacent sides of the reversible contactor as needed. The same side of the reversible contactor can also be set with two or more second clips.

[0025] In some examples, the first clamping member is a clamping block, the clamping block is provided with two clamping teeth arranged at intervals, the first clamping structure is a clamping groove provided on the base, and the two clamping teeth on the clamping block are respectively clamped into the corresponding clamping grooves.

[0026] The arrangement of the clamping block can provide a stronger connection stability, and through the cooperation of the clamping block and the clamping slot, the connection between the two bases can be made more stable and reliable.

[0027] Specifically, the clamping block has two clamping teeth that can realize the clamping function. The two clamping teeth are configured to cooperate with the first clamping structure on the base. The first clamping structure at this time can be a clamping groove arranged on the base.

[0028] The two engaging teeth on the engaging block can be inserted into the corresponding engaging grooves. This process is not only simple and quick, but also greatly enhances the stability of the connection part. Through this arrangement, the interaction between the engaging block and the engaging groove is strengthened, so that the connection between the two bases becomes more stable, ensuring the reliability of the connection.

[0029] In some examples, an embedding half groove is opened on the base, and when two bases are connected, the two embedding half grooves are spliced ​​to form an embedding groove, and the first clamping structure is a clamping groove arranged on the inner wall of the embedding groove.

[0030] The first clamping member is a clamping block, the clamping block is embedded in the embedding groove, the clamping block is provided with two clamping teeth arranged at intervals, and the two clamping teeth are respectively clamped into the corresponding clamping grooves.

[0031] After the base is provided with an embedding half groove, the two embedding half grooves can be relatively perfectly assembled together during the mutual connection of the two bases to form a complete embedding groove. The inner wall of the embedding groove can be provided with a first clamping structure, specifically a clamping groove.

[0032] After the first clamping member is set as a clamping block, the clamping block can be relatively perfectly embedded in the embedding groove. The clamping block is provided with two clamping teeth arranged at intervals. The two clamping teeth can be respectively clamped into the corresponding clamping grooves, thereby realizing a stable connection between the two bases.

[0033] In some examples, the engaging teeth are provided with engaging inclined surfaces, and the engaging inclined surfaces abut against the inner wall of the engaging groove. During the engaging process of the two engaging teeth, the two engaging inclined surfaces press the two engaging grooves in a direction of being relatively close to each other.

[0034] The docking bevel can enable the locking teeth to form a locking pre-tightening force on the inner wall of the locking groove during the locking process, thereby achieving a tightening effect, making the effect of the locking block better after locking, and achieving a seamless effect, so that the two bases are less likely to separate accidentally under the locking of the locking block.

[0035] In some examples, the second clamping member is a clamping plate, the clamping plate is provided with two clamping protrusions spaced apart from each other, the shell is provided with a clamping groove matched with the clamping protrusions, and the second clamping structure includes the clamping groove.

[0036] The two clamping protrusions are clamped to the two corresponding clamping grooves on the two shells at the same time.

[0037] The setting of the clamping plate can have a larger clamping range, the clamping protrusion is the clamping body of the clamping plate, and the two clamping protrusions are connected to the main body of the clamping plate. The clamping groove on the housing can be adapted to the clamping protrusion and realize clamping.

[0038] Specifically, after two snap-in protrusions are set on the snap-in plate, the shell is provided with a snap-in groove that cooperates with the snap-in protrusion. Through the matching setting of the snap-in protrusion and the snap-in groove, the snap-in plate can have a wider range of snap-in functions and applicability. The snap-in protrusions serve as the snap-in parts on the snap-in plate, and the snap-in protrusions are firmly connected to the main structure of the snap-in plate. The snap-in grooves on the shell are used to precisely dock with the snap-in protrusions to achieve an effective snap-in function. Such a setting not only enhances the stability and reliability of the snap-in parts, but also improves their flexibility and extensiveness in practical applications. The two shells are connected together by the snap-in plate, which provides better connection stability.

[0039] In some examples, the housing is further provided with a guide groove which is in communication with the engaging groove.

[0040] The guide groove can improve the assembly efficiency of the clamping plate, and the clamping protrusion can be quickly clamped to the clamping groove through the guide groove.

[0041] In some examples, the snap plate is provided with a snap, and the snap can be snapped to the inner wall of the snap groove; or,

[0042] When the housing is further provided with a guide groove connected with the clamping groove, the buckle is clamped to the inner wall of the guide groove.

[0043] The setting of the buckle can limit the clamping position of the clamping plate, which effectively limits the position of the clamping plate, thereby greatly reducing the possibility of the clamping plate accidentally falling off during operation. The entire clamping plate can be limited by clamping the buckle to the inner wall of the clamping groove or the guide groove.

[0044] The housing assembly may further include a cover body, and at least one wall of the guide groove may be formed in the configuration of the cover body and the housing, and the buckle may be snapped onto the cover body. A guide slope may be provided on the buckle, and when a sufficiently large external force is applied to the position where the buckle is snapped, the buckle may temporarily break away from the snap-on limit state.

[0045] In some examples, the mechanical linkage includes a support member and a rocker arm, wherein the support member is mounted in the assembly cavity, and the rocker arm is swingably connected to the support member.

[0046] A locking structure is arranged on the swing rod, a limiting protrusion is arranged in the assembly groove, and the limiting protrusions of the two contactor units are both connected to the locking structure.

[0047] The mechanical linkage is mainly composed of support members and swing rods, which can realize specific functions and operations. Among them, the support member is firmly installed in the assembly cavity, playing the main structural support role, ensuring the overall stability and reliability. The swing rod is connected to the support member in a flexible way and can swing, thereby realizing the linkage between mechanical parts.

[0048] A chain structure is set in the setting of the swing lever. The function of this structure is to play a role in time under certain conditions, such as abnormal instructions caused by mechanical vibration or operator errors, to ensure the safe operation of the mechanical system. In the setting of the assembly groove, limit protrusions are set in it, and these protrusions play an important limiting role. More importantly, the limit protrusions of the two contactor units do not exist in isolation. They are connected to the chain structure through corresponding mechanical connections, forming a relatively strict mechanical linkage system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0061] To solve the above technical problems, please refer to Figure 1-Figure 8 As shown, the present application proposes a reversible contactor, which can make the structure of the reversible contactor more compact, save the occupied space of the entire reversible contactor, and improve space utilization.

[0062] Reference Figure 1 and 2 In some examples, the reversible contactor includes two contactor units 100, at least one clip 200, and a mechanical interlock 300:

[0063] Two contactor units 100, each of which comprises a housing assembly, and two opposite sides of the housing assembly are respectively provided with assembly grooves 140.

[0064] At least one clamping member 200 is used to connect two contactor units 100. When the two contactor units 100 are connected to each other, the assembly grooves 140 on the two contactor units 100 are butted against each other to form an assembly cavity.

[0065] The mechanical interlock 300 is installed in the assembly cavity. The size of the mechanical interlock 300 is smaller than or equal to the size of the assembly cavity, so that the mechanical interlock 300 is completely located in the assembly cavity.

[0066] The present application proposes a reversible contactor, the core goal of which is to optimize the structural layout to achieve more efficient space saving. Through this arrangement, the overall volume of the reversible contactor will be effectively reduced, thereby achieving higher space utilization in a limited space, which is particularly important for modern electronic devices that pursue high-density installation.

[0067] Specifically, the reversible contactor may include two contactor units 100, at least one clamping member 200, and a set of mechanical interlocks 300. The two contactor units 100 form the basis of the reversible contactor, and each unit includes a housing assembly. The opposite sides of the housing assembly may be provided with assembly grooves 140, respectively, and these assembly grooves 140 may provide clearance spaces for the close arrangement of the contactor units 100, and these clearance spaces may be used to assemble the mechanical interlocks 300.

[0068] The clip 200 in the present application has the function of connecting two contactor units 100. Compared with the method of connecting the contactor unit 100 to the cabinet or guide rail in the electric cabinet in the prior art, the connection stability is better, and the reversible contactor is no longer a simple splicing. The entire reversible contactor can be formed into a relative whole through the clip 200.

[0069] When two contactor units 100 are connected to each other, the respective assembly grooves 140 of the two contactor units 100 can be precisely butted together to form a common assembly cavity. This arrangement not only enhances the structural stability of the contactor, but also facilitates subsequent assembly and maintenance.

[0070] The entire mechanical interlock 300 can be completely installed in the assembly cavity. Specifically, the size of the mechanical interlock 300 can be set to be less than or equal to the size of the assembly cavity, ensuring that the mechanical interlock 300 can be completely accommodated in the assembly cavity. Such a setting not only ensures the safety of the contactor during operation, but also saves the installation space of the mechanical interlock 300, making the entire reversible contactor more compact and occupying less space overall.

[0071] The housing assembly in the reversible contactor of the present application can accommodate the mechanical interlock 300 and form a compact reversible contactor, which can effectively reduce the volume of the reversible contactor, thereby saving the space of the cabinet where the reversible contactor is located. Not only can the space of the equipment be optimized, but also the overall performance and reliability of the equipment can be improved while ensuring functionality.

[0072] Reference Figure 1 and Figure 2 In some examples, the housing assembly includes a base 110 and a shell 120 , and the base 110 is fixedly connected to or integrally provided with the shell 120 .

[0073] The base 110 is provided with a first clamping structure, the shell 120 is provided with a second clamping structure 121 , and the clamping member 200 includes a first clamping member 200 connected to the base 110 and a second clamping member 200 connected to the shell 120 .

[0074] When the two contactor units 100 are connected to each other, the first clamping member 200 is clamped to the corresponding first clamping structures on the two bases 110 at the same time, and the second clamping member 200 is clamped to the corresponding second clamping structures 121 on the two shells 120 at the same time.

[0075] The housing assembly of the present application may include a base 110 and a shell 120, which may be combined by a fixed connection or an integrated setting; the main function of the base 110 is to support and install various functional components in the contactor unit 100, while the shell 120 is responsible for protecting these functional components. The connection between the base 110 and the shell 120 includes a fixed connection or an integrated setting, and in the fixed connection, various methods such as clamping, clamping, bonding, screws, and bolts may be used for fixing.

[0076] A first clamping structure is provided on the base 110, and a second clamping structure 121 is provided on the shell 120, and the two clamping structures are connected by a first clamping component 200 and a second clamping component 200 respectively; when the two contactor units 100 need to be connected to each other, the first clamping component 200 will be simultaneously clamped on the corresponding first clamping structures on the two bases 110, and the second clamping component 200 will also be simultaneously clamped on the corresponding second clamping structures 121 on the two shells 120.

[0077] The first clamping structure and the first clamping member 200 are used together to effectively connect the bases 110 of the two contactor units 100, and the second clamping structure 121 and the second clamping member 200 are used together to connect the shells 120 of the two contactor units 100. Such a double connection structure makes the entire connection more stable and reliable. In addition, the base 110 and the shell 120 in each contactor unit 100 are also connected in some way. Combined with the above-mentioned double connection, the stability of the entire reversible contactor is significantly improved.

[0078] Reference Figure 1 and 2 In some examples, at least two first clamping members 200 are provided, at least two first clamping members 200 are located at different positions of the reversible contactor, and each first clamping member 200 is simultaneously clamped to two first clamping structures on the same side of the two bases 110; and / or

[0079] At least two second clamping members 200 are provided, and the at least two second clamping members 200 are located at different positions of the reversible contactor. Each second clamping member 200 is simultaneously clamped on two second clamping structures 121 located on the same side of the two housings 120 .

[0080] In the above structure, at least two first clamping members 200 can realize multi-point connection between the two bases 110, thereby further improving the connection stability between the two bases 110. The first clamping member 200 can be connected to the junction of the two bases 110, and two first clamping members 200 can be set as needed. The two first clamping members 200 can be respectively set on different sides of the reversible contactor, specifically on the opposite sides of the reversible contactor, and the first clamping members 200 can be respectively set on the adjacent two sides of the reversible contactor as needed. The same side of the reversible contactor can also be provided with two or more first clamping members 200.

[0081] In contrast, in the above structure, at least two second clamping members 200 can realize multi-point connection between the two housings 120, thereby further improving the connection stability between the two housings 120. The second clamping member 200 can be connected at the junction of the two housings 120, and two second clamping members 200 can be set as needed. The two second clamping members 200 can be respectively set on different sides of the reversible contactor, specifically on the opposite sides of the reversible contactor, and the second clamping members 200 can be respectively set on the adjacent sides of the reversible contactor as needed. Two or more second clamping members 200 can also be set on the same side of the reversible contactor.

[0082] Referring to , 2 and 3, in some examples, the first clamping member 200 is a clamping block 210, and the clamping block 210 is provided with two clamping teeth 211 arranged at intervals (see 6 and Figure 7 ), the first clamping structure is a clamping groove 111 arranged on the base 110, and the two clamping teeth 211 on the clamping block 210 are respectively clamped into the corresponding clamping groove 111.

[0083] The arrangement of the clamping block 210 can provide a stronger connection stability. Through the cooperation between the clamping block 210 and the clamping slot 111 , the connection between the two bases 110 can be made more stable and reliable.

[0084] Specifically, the clamping block 210 has two clamping teeth 211 that can realize the clamping function. The two clamping teeth 211 are configured to cooperate with the first clamping structure on the base 110. The first clamping structure at this time can be a clamping groove 111 provided on the base 110.

[0085] The two engaging teeth 211 on the engaging block 210 can be inserted into the corresponding engaging grooves 111. This process is not only simple and quick, but also greatly enhances the stability of the connection part. Through this arrangement, the interaction between the engaging block 210 and the engaging groove 111 is strengthened, so that the connection between the two bases 110 becomes more stable, ensuring the reliability of the connection.

[0086] The above-mentioned setting of the present application not only improves the connection stability, but also has the advantages of easy installation and disassembly. The user does not need to use complicated tools, and only needs to insert the engaging teeth 211 of the engaging block 210 into the engaging groove 111 of the base 110 according to the predetermined setting to quickly complete the connection of the two components. When disassembly is required, it is only necessary to pull out the engaging teeth 211 accordingly to achieve quick disassembly. This setting improves work efficiency and also reduces the risks that may be caused by improper operation.

[0087] In addition, the engagement teeth 211 of the engagement block 210 and the engagement groove 111 can be matched with high precision, which also helps to improve the durability of the entire connection structure. Even in the process of frequent assembly and disassembly, the integrity of the structure and the reliability of the connection can be maintained, thereby extending the service life of the device.

[0088] The matching arrangement of the clamping block 210 and the clamping slot 111 of the present application not only enhances the stability of the connection, but also improves the convenience of operation and the durability of the entire device.

[0089] Refer to 2 and Figure 3In some examples, an embedding half groove 112 is opened on the base 110. When two bases 110 are connected, the two embedding half grooves 112 are spliced ​​to form an embedding groove 113. The first clamping structure is a clamping groove 111 arranged on the inner wall of the embedding groove 113.

[0090] The first clamping member 200 is a clamping block 210 , which is embedded in the embedding groove 113 . The clamping block 210 is provided with two clamping teeth 211 disposed at intervals, and the two clamping teeth 211 are respectively clamped into the corresponding clamping grooves 111 .

[0091] The arrangement of the clamping block 210 can provide a stronger connection stability. Through the cooperation between the clamping block 210 and the clamping groove 111, the connection between the two bases 110 can be more stable and reliable. The embedding groove 113 can improve the connection stability of the clamping block 210, and the inner wall of the embedding groove 113 can better limit the clamping block 210.

[0092] After the base 110 is provided with the embedding half groove 112, the two embedding half grooves 112 can be relatively perfectly assembled together during the connection of the two bases 110 to form a complete embedding groove 113. The inner wall of the embedding groove 113 can be provided with a first clamping structure, specifically a clamping groove 111.

[0093] After the first clamping member 200 is configured as a clamping block 210, the clamping block 210 can be relatively perfectly embedded in the embedding groove 113. The clamping block 210 is provided with two spaced clamping teeth 211. The two clamping teeth 211 can be respectively clamped into the corresponding clamping grooves 111, thereby achieving a stable connection between the two bases 110.

[0094] The arrangement of the clamping block 210 can improve the stability of the connection. Through the cooperation between the clamping block 210 and the clamping groove 111, the connection between the two bases 110 can be more stable and reliable. At the same time, the arrangement of the embedded groove 113 can further improve the connection stability of the clamping block 210. The inner wall of the embedded groove 113 can better limit the clamping block 210, thereby ensuring the stability of the connection. This arrangement can not only improve the stability of the connection, but also improve the reliability of the connection, making the connection more firm and not easy to loosen.

[0095] In some examples, the engaging teeth 211 are provided with a butt-jointed inclined surface 212, which abuts against the inner wall of the engaging groove 111. During the engaging process of the two engaging teeth 211, the two butt-jointed inclined surfaces 212 press the two engaging grooves 111 in a direction of being relatively close to each other. Figure 7 .

[0096] The docking slope 212 can enable the engaging teeth 211 to form a clamping pre-tightening force on the inner wall of the engaging groove 111 during the clamping process, thereby achieving a clamping-tighter effect, making the clamping block 210 more effective after clamping and achieving a seamless fit, so that the two bases 110 are less likely to be accidentally separated under the clamping of the clamping block 210.

[0097] Specifically, the butt bevel 212 can closely abut and fit against the inner wall of the clamping groove 111. When the clamping operation is performed, the two clamping teeth 211 cooperate with each other, and the two butt bevels 212 apply pressure to the two clamping grooves 111 to make them move closer to each other. This arrangement realizes the generation of a clamping pre-tightening force on the inner wall of the clamping groove 111 during the clamping process, which can be used as the initial pressure before clamping.

[0098] The clamping pre-tightening force is generated by the butt bevel 212 during the clamping action, and increases as the clamping action is completed, thereby achieving a unique effect of getting tighter as the clamping action is completed. This effect is particularly obvious after the clamping block 210 is clamped, making the connection between the clamping block 210 and the clamped object tighter, achieving a relatively tight fit. This tight clamping effect significantly improves the stability of the two bases 110 under the action of the clamping block 210, and reduces the risk of accidental separation due to looseness. Such a setting not only enhances the reliability of the clamping structure, but also improves the overall service life and safety.

[0099] Reference Figure 4 and Figure 5 In some examples, the second clamping member 200 is a clamping plate 220 , on which two clamping protrusions 221 spaced apart are provided, and on the shell 120 , a clamping groove 1211 matching the clamping protrusion 221 is provided, and the second clamping structure 121 includes the clamping groove 1211 .

[0100] The setting of the clamping plate 220 can have a larger clamping range, the clamping protrusion 221 is the clamping body of the clamping plate 220, and the two clamping protrusions 221 are connected to the main part of the clamping plate 220. The clamping groove 1211 on the housing 120 can be adapted to the clamping protrusion 221 and realize the clamping.

[0101] Specifically, after two clamping protrusions 221 are provided on the clamping plate 220, a clamping groove 1211 that cooperates with the clamping protrusion 221 is included in the setting of the housing 120. Through the matching setting of the clamping protrusion 221 and the clamping groove 1211, the clamping plate 220 can have a wider clamping function and applicability. The clamping protrusion 221 serves as a clamping part on the clamping plate 220, and the clamping protrusion 221 is firmly connected to the main structure of the clamping plate 220. The function of the clamping groove 1211 on the housing 120 is to precisely dock with the clamping protrusion 221, so as to achieve an effective clamping function. Such a setting not only enhances the stability and reliability of the clamping member 200, but also improves their flexibility and extensiveness in practical applications.

[0102] The two clamping protrusions 221 are simultaneously clamped to the two corresponding clamping grooves 1211 on the two housings 120. In this way, the two housings 120 can be connected together through the clamping plate 220, which can provide better connection stability.

[0103] The clamping protrusion 221 can be a "T"-shaped, "L"-shaped or dovetail-shaped structure, and the corresponding clamping groove 1211 is a matching "T"-shaped groove, "L"-shaped groove or dovetail groove. The clamping protrusion 221 can be slidably connected with the clamping groove 1211 and limited. Specifically, the clamping protrusion 221 can be slid into the clamping groove 1211 to achieve clamping.

[0104] The two snap-fitting grooves 1211 may be provided with matching inclined surfaces with gradually varying spacings, so that when the snap-fitting protrusion 221 slides and connects to the snap-fitting groove 1211 , a tightening effect can be achieved, thereby increasing the snap-fitting stability and making the connection effect of the two shells 120 better.

[0105] In some examples, the housing 120 is further provided with a guide groove 1212 (see Figures 1 to 3 The guide groove 1212 can improve the assembly efficiency of the clamping plate 220 , and the clamping protrusion 221 can be quickly clamped to the clamping groove 1211 through the guide groove 1212 .

[0106] After a guide groove 1212 connected to the snap-in groove 1211 is provided on the shell 120, the setting of the guide groove 1212 can effectively improve the assembly efficiency of the snap-in plate 220. Through the guide groove 1212, the snap-in protrusion 221 can be quickly and accurately snapped into the snap-in groove 1211, thereby improving the efficiency and accuracy of assembly.

[0107] In some examples, the snap plate 220 is provided with a snap 222, and the snap 222 can be snapped to the inner wall of the snap groove 1211; or,

[0108] When a guide groove 1212 communicating with the engaging groove 1211 is further provided on the housing 120 , the buckle 222 is engaged with the inner wall of the guide groove 1212 .

[0109] The arrangement of the buckle 222 can limit the clamping position of the clamping plate 220, which effectively limits the position of the clamping plate 220, thereby greatly reducing the possibility of the clamping plate 220 accidentally falling off during operation. By clamping the buckle 222 to the inner wall of the clamping groove 1211 or the guide groove 1212, the entire clamping plate 220 can be limited.

[0110] The housing assembly may further include a cover body 130, and at least one wall of the guide groove 1212 may be formed in the configuration of the cover body 130 and the housing 120, and the buckle 222 may be snapped onto the cover body 130. The buckle 222 may be provided with a guiding inclined surface, and when a sufficiently large external force is applied to the snap-on position of the buckle 222, the state of snap-on limit may be temporarily released.

[0111] In order to facilitate the use of the operator, a grip portion 223 may be provided on the back side of the clamping plate 220 away from the housing 120. The provision of the grip portion 223 allows the operator to easily apply force, so that the clamping plate 220 can be quickly assembled and disassembled even without using any tools. Such a provision not only improves work efficiency, but also reduces the complexity and intensity of operation.

[0112] Reference Figure 8 In some examples, the mechanical linkage 300 includes a support member 310 and a swing rod 320 , wherein the support member 310 is installed in the assembly cavity, and the swing rod 320 is swingably connected to the support member 310 .

[0113] A locking structure 321 is disposed on the swing rod 320 , a limiting protrusion 141 is disposed in the assembly groove 140 , and the limiting protrusions 141 of the two contactor units 100 are both connected to the locking structure 321 .

[0114] Such a configuration can ensure that the two contactor units 100 will not be closed at the same time under the command triggered by mechanical vibration or operation error.

[0115] The mechanical linkage 300 is mainly composed of a support member and a swing rod, which can realize specific functions and operations. Among them, the support member is firmly installed in the assembly cavity, playing the main structural support role, ensuring the overall stability and reliability. The swing rod is connected to the support member in a flexible way and can swing, thereby realizing the linkage between the mechanical parts.

[0116] A chain structure 321 is provided in the setting of the swing lever. The function of this structure is to play a role in time under certain conditions, such as abnormal instructions caused by mechanical vibration or operator errors, to ensure the safe operation of the mechanical system. In the setting of the assembly groove 140, the limit protrusions 141 are provided therein, and these protrusions play an important role in limiting. More importantly, the limit protrusions 141 of the two contactor units 100 do not exist in isolation. They are connected to the chain structure 321 through corresponding mechanical connections, forming a relatively strict mechanical linkage system.

[0117] Such a configuration can effectively prevent the simultaneous closing of the two contactor units 100 in many situations, especially when facing mechanical vibration or operating errors. This configuration not only improves the safety and reliability of the mechanical system, but also increases the stability and predictability of the operation.
