Description

Technical Field

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

[0002] Contactors are electrical control components that play a key role in automation control circuits. Their main functions include switching, controlling, and protecting circuits. Due to their reliability and stability, these components are widely used in various industrial and home automation systems.

[0003] In the contactor products currently on the market, the secondary circuit terminal of the contactor is located at the front end of the contactor, which means that when connecting the wire from the incoming end to the secondary circuit terminal of the contactor, the wire must bypass the front end of the contactor and pass through the terminal at the outgoing end.

[0004] The above arrangement will cause the wire to partially cover the contactor, thereby affecting the visual effect of the entire contactor, making the contactor appear less neat and beautiful. Utility Model Content

[0005] The present application provides a contactor and an electrical device, which can solve the problem that the connecting wire is exposed outside the contactor during connection.

[0006] In a first aspect, the present application provides a contactor, the contactor comprising a wiring cover and a wiring assembly. The wiring cover has a receiving cavity; the wiring assembly is arranged in the receiving cavity, and the wiring assembly comprises a secondary circuit inlet terminal and a secondary circuit outlet terminal arranged opposite to each other.

[0007] Among them, a receiving through hole is opened on the wiring cover body, and the receiving through hole passes through the wiring cover body. The receiving through hole is located on one side of the wiring assembly, and the connecting wire of the secondary circuit input terminal or the secondary circuit output terminal is passed through the receiving through hole.

[0008] A housing cavity is specially provided inside the wiring cover, and its main function is to provide a fixed space for the wiring assembly. The wiring assembly is placed in this housing cavity, and the wiring assembly may include a secondary circuit inlet terminal and a secondary circuit outlet terminal, which are relatively placed in the housing cavity, and two corresponding wiring holes are opened on the wiring cover. The above arrangement can facilitate the circuit connection of the secondary circuit.

[0009] The present application provides a specific receiving through hole on the wiring cover. The receiving through hole runs through the entire wiring cover and is located on one side of the wiring assembly as a whole, so that the connecting wires of the secondary circuit inlet and the secondary circuit outlet can pass through the through hole. This arrangement solves the problem of the connecting wires being exposed outside the contactor during connection.

[0010] In some examples, an insulating partition is disposed between the accommodating through hole and the accommodating cavity.

[0011] An insulating partition is placed between the receiving through hole and the receiving cavity, and the insulating partition can be integrally arranged on the wiring cover. The setting of the insulating partition can prevent interference between the wiring assembly inside the receiving cavity and the connecting wire in the receiving through hole, thereby significantly improving the system stability of the contactor. This stability is crucial to ensure the reliability of the electrical connection and the long-term trouble-free operation of the contactor.

[0012] In some examples, there is an arc transition between two adjacent wall surfaces in the receiving through hole.

[0013] An arc-shaped transition is used between two adjacent walls of the receiving through hole. This structure ensures that the connection between the walls of the receiving through hole is more firm and stable, reducing the risk of damage caused by stress concentration. This arc transition improves the overall strength and durability of the receiving through hole in structure, and helps the receiving through hole to withstand greater force and pressure without deformation or damage.

[0014] In some examples, an easily detachable structure is provided on a wall surface of the accommodating through hole facing away from the wiring assembly, and the easily detachable structure can fall off under the action of an external force and form an avoidance gap.

[0015] In the above structure, at least one detachable structure, that is, an easily detachable structure, can be provided on the wall of the accommodating through hole away from the wiring assembly. When affected by external force, the easily detachable structure can fall off more easily and form an obvious avoidance gap after falling off.

[0016] In practical applications, such a setting allows the avoidance gap to be opened at any time, so that electronic components such as surge modules can be easily inserted into the accommodating through holes, thereby improving the utilization efficiency of the entire space.

[0017] In addition, a circle of easy-to-remove through holes is provided around the easy-to-remove structure. This arrangement effectively reduces the connection strength between the easy-to-remove structure and other parts of the wiring cover, making it easier for users to manually remove the easy-to-remove structure.

[0018] In some examples, at least one knock-out tool hole is provided on a peripheral side of the easily detachable structure.

[0019] The easily detachable structure provided in the present application is provided with one or more knock-off tool holes around its periphery. These knock-off tool holes are essentially relatively spacious through holes that can accommodate tools. Such a setting is considered to allow the tool to be easily inserted into the hole, so that the knock-off action can be performed more easily, making the disassembly process of the easily detachable structure simpler.

[0020] Through the above settings, the existence of the knock-off tool hole significantly reduces the complexity of the disassembly work, allowing the operator to complete the disassembly task with less effort and time. Such a setting not only improves work efficiency, but also reduces labor costs, while improving the convenience and reliability of the overall operation. Therefore, the ingenious setting of the knock-off tool hole is an important detail in the easy-to-disassemble structure setting, which improves user needs and operational convenience.

[0021] In some examples, the avoidance gap is formed on the wall surface of the accommodating through hole facing away from the wiring assembly, and the avoidance gap is connected to the accommodating through hole.

[0022] At least one avoidance gap is provided on the wall of the receiving through hole away from the wiring assembly. These avoidance gaps are connected with the receiving through hole, and such a setting allows electronic components such as surge modules to be more conveniently placed in the receiving through hole during installation. Such a structural layout not only optimizes the efficiency of space use, but also enhances the functionality of the entire wiring cover.

[0023] In some examples, the contactor further includes a surge module, the surge module is connected to the wiring cover, the surge module is arranged on a side of the wiring assembly away from the accommodating through hole, and the surge module partially protrudes from the outer surface of the contactor;

[0024] When the two contactors are connected, the surge module on one of the contactors can be plugged into the avoidance notch on the other contactor.

[0025] The surge module can protect the circuit and prevent equipment damage caused by a sudden increase in current. The surge module is tightly connected to the wiring cover to ensure its stability and reliability.

[0026] During installation, the surge module is placed on one side of the wiring assembly, which is away from the receiving through hole. Due to its arrangement, a portion of the surge module protrudes from the outer surface of the contactor, which may have a certain impact on the overall appearance of the contactor, but this impact is negligible because it plays an important protective role.

[0027] When two contactors need to be connected together, the surge module on one contactor can be easily inserted into the avoidance gap on the other contactor. This arrangement not only allows the surge module and other devices to be smoothly inserted into the receiving through hole, improving the efficiency of space utilization, but also effectively reduces the width of the two contactors when they are arranged side by side, which plays an important role in saving space and improving the compactness of the equipment.

[0028] In some examples, the surge module includes a main body and an embedded portion, the main body is connected to the wiring cover, the embedded portion is arranged on a side of the main body away from the wiring cover, the embedded portion protrudes from an outer surface of the contactor, and the embedded portion can be embedded in the accommodating through hole from the avoidance notch.

[0029] The main body is connected to the wiring cover to ensure the stability of the entire device. The embedded part is arranged on the side of the main body away from the wiring assembly, and the embedded part can protrude and be away from the wiring cover. Such a layout allows the embedded part to protrude significantly from the outer surface of the contactor, thereby enhancing its protective effect.

[0030] It is worth mentioning that the embedded part can be easily inserted into the receiving through hole from the avoidance notch. The setting of the avoidance notch not only enables the embedded part of the surge module to be smoothly embedded into the receiving through hole, but also greatly improves the utilization rate of the space. In this way, the setting of the entire electronic device is more compact and the use efficiency is significantly improved.

[0031] In some examples, the contactor further includes a base and a shell, the base is connected to the shell, and the wiring cover is disposed on the shell.

[0032] The structure of the base and the shell ensures the overall stability of the contactor. The shell acts as an external protective layer, providing good protection for the internal components. In addition, the addition of the wiring cover not only provides an upper cover for the contactor, but also makes the wiring operation more convenient, further improving the practicality of the contactor.

[0033] The above arrangement makes the installation and assembly process of the contactor more stable and reliable. Among the various components of the contactor, the base, the shell and the wiring cover together form a large accommodating cavity. This accommodating cavity provides a spacious installation space for various functional components of the contactor, making the internal layout of the contactor more reasonable, and various functional components can be effectively protected and fixed, thereby improving the overall performance of the contactor.

[0034] In a second aspect, the present application provides an electrical device comprising at least one of the above-mentioned contactors.

[0035] The contactor described above in the present application can solve the problem of the connection wires being exposed outside the contactor when connected. Specifically, the present application provides a specific accommodating through hole on the wiring cover. The accommodating through hole runs through the entire wiring cover, and the accommodating through hole is located on one side of the wiring assembly as a whole, so that the connection wires of the secondary circuit inlet and the secondary circuit outlet can pass through this through hole. The need for winding wires from the front end is avoided, and the front end of the contactor (the area where the wiring cover is located) is effectively kept neat and beautiful. This not only improves the appearance quality of the equipment, but also improves the orderliness of the line connection, which helps to facilitate operation during maintenance and overhaul.

DETAILED DESCRIPTION

[0043] 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.

[0044] To solve the above technical problems, please refer to Figure 1-Figure 4As shown, the first aspect of the present application provides a contactor, which can solve the problem that the connecting wire is exposed outside the contactor during connection.

[0045] Reference Figure 1 and Figure 2 As shown, in some examples, the contactor includes a wiring cover 100 and a wiring assembly 200. The wiring cover 100 has a receiving cavity; the wiring assembly 200 is arranged in the receiving cavity, and the wiring assembly 200 includes a secondary circuit inlet terminal 210 and a secondary circuit outlet terminal 220 arranged opposite to each other.

[0046] Among them, a receiving through hole 110 is opened on the wiring cover body 100, and the receiving through hole 110 passes through the wiring cover body 100. The receiving through hole 110 is located on one side of the wiring assembly 200, and the connecting wire of the secondary circuit input terminal 210 or the secondary circuit output terminal 220 is passed through the receiving through hole 110.

[0047] A receiving cavity is specially provided inside the wiring cover 100, and its main function is to provide a fixed space for the wiring assembly 200. The wiring assembly 200 is placed in the receiving cavity, and the wiring assembly 200 may include a secondary circuit inlet terminal 210 and a secondary circuit outlet terminal 220, which are relatively arranged in the receiving cavity, and two corresponding wiring holes are opened on the wiring cover 100, and the above arrangement can facilitate the circuit connection of the secondary circuit.

[0048] The present application sets a specific receiving through hole 110 on the wiring cover 100. The receiving through hole 110 runs through the entire wiring cover 100, and the receiving through hole 110 is located on one side of the wiring assembly 200 as a whole, so that the connecting wire of the secondary circuit inlet terminal 210 or the secondary circuit outlet terminal 220 can be accommodated in the through hole 110. Such a setting solves the problem that the connecting wire is exposed outside the contactor during connection.

[0049] Specifically, the connecting wire of the secondary circuit inlet terminal 210 can be placed in the accommodating through hole 110; the connecting wire of the secondary circuit outlet terminal 220 can also be placed in the accommodating through hole 110 as needed; or the connecting wire of the secondary circuit inlet terminal 210 and the connecting wire of the secondary circuit outlet terminal 220 can be both placed in the accommodating through hole 110; when the connecting wire of the secondary circuit inlet terminal 210 and the connecting wire of the secondary circuit outlet terminal 220 are one connecting wire, they can also be placed in the accommodating through hole 110.

[0050] In the prior art, when connecting the wire from the secondary circuit inlet 210 to the secondary circuit outlet 220 of the contactor, the wire needs to go around the terminal of the outlet from the front end of the contactor. If there is no reasonable setting, such winding may cause the wire to appear messy, and the connecting wire may be exposed on the outside of the contactor, affecting the overall aesthetics of the contactor.

[0051] In the present application, by providing a receiving through hole 110 on the wiring cover 100, the wire can directly pass through the receiving through hole 110 through the wiring cover 100, avoiding the need to wind the wire from the front end, and effectively keeping the front end of the contactor (the area where the wiring cover 100 is located) neat and beautiful. This not only improves the appearance quality of the device, but also improves the orderliness of the line connection, which is conducive to the convenience of operation during maintenance and repair.

[0052] In some examples, an insulating partition is disposed between the receiving through hole 110 and the receiving cavity.

[0053] An insulating partition is placed between the receiving through hole 110 and the receiving cavity, and the insulating partition can be integrally arranged on the wiring cover 100. The arrangement of the insulating partition can prevent interference between the wiring assembly 200 inside the receiving cavity and the connecting wire in the receiving through hole 110, thereby significantly improving the system stability of the contactor. This stability is crucial to ensure the reliability of the electrical connection and the long-term trouble-free operation of the contactor.

[0054] Therefore, the provision of the insulating partition can effectively prevent interference between the wiring assembly 200 in the receiving cavity and the connecting wire in the receiving through hole 110. Because of the avoidance of such interference, the stability of the entire contactor is significantly improved.

[0055] In some examples, two adjacent wall surfaces in the receiving through hole 110 have an arc transition.

[0056] An arc-shaped transition is used between two adjacent walls of the receiving through hole 110. Such a structure ensures that the connection between the walls of the receiving through hole 110 is more firm and stable, and reduces the risk of damage caused by stress concentration. This arc transition improves the overall strength and durability of the receiving through hole 110 in terms of structure, and helps the receiving through hole 110 to withstand greater forces and pressures without deformation or damage.

[0057] In addition, in order to further enhance the structural strength and stability of the receiving through hole 110, reinforcing ribs can be provided on the inner wall of the receiving through hole 110 according to actual needs. These reinforcing ribs can be provided inside the receiving through hole 110 or on the outer wall surface corresponding to the receiving through hole 110.

[0058] Through the role of the reinforcing ribs, various stresses generated by the operation of the internal circuit can be effectively dispersed and borne, thereby further improving the mechanical strength and service life of the receiving through hole 110 and the entire contactor. This setting takes into account the complex situations that may be encountered in actual applications and ensures the stability and reliability of the contactor under different working conditions.

[0059] Reference Figure 1 and Figure 2 As shown, in some examples, an easily removable structure 120 is provided on the wall of the receiving through hole 110 away from the wiring assembly 200, and the easily removable structure 120 can fall off under the action of an external force and form an avoidance gap 130. The provision of the easily removable structure 120 can open the avoidance gap 130 in time when needed, so that devices such as the surge module 300 can be inserted into the receiving through hole 110, thereby improving the utilization rate of the space.

[0060] A circle of easily detachable through holes is provided around the easily detachable structure 120 , which can reduce the connection strength between the easily detachable structure 120 and other parts of the corresponding wiring cover 100 , making it easier to manually remove the easily detachable structure 120 .

[0061] In the above structure, at least one detachable structure, namely, an easily detachable structure 120, can be provided on the wall of the receiving through hole 110 away from the wiring assembly 200. When affected by external force, the easily detachable structure 120 can fall off more easily and form an obvious avoidance gap 130 after falling off.

[0062] With such a configuration, in practical applications, the avoidance gap 130 can be opened at any time, so that electronic components such as the surge module 300 can be easily inserted into the accommodating through hole 110, thereby improving the utilization efficiency of the entire space.

[0063] In addition, a circle of easy-to-remove through holes is provided around the easy-to-remove structure 120. This arrangement effectively reduces the connection strength between the easy-to-remove structure 120 and other parts of the wiring cover 100, making it easier for the user to manually remove the easy-to-remove structure 120. Such detailed arrangements not only improve the convenience of the product, but also reflect the in-depth consideration of the setter for the user experience.

[0064] Reference Figure 1 and Figure 2 As shown, in some examples, at least one knock-off tool hole 140 is provided on the peripheral side of the easily detachable structure 120. The knock-off tool hole 140 can be a relatively large through hole into which a tool can be inserted, and the provision of the knock-off tool hole 140 can further reduce the difficulty of disassembling the easily detachable structure 120.

[0065] The easily detachable structure 120 provided in the present application is provided with one or more knock-off tool holes 140 around its periphery. These knock-off tool holes 140 are substantially configured as relatively spacious through holes capable of receiving tools. Such a configuration is considered to allow the tool to be conveniently inserted into the hole, so that the knock-off action can be performed more easily, making the disassembly process of the easily detachable structure 120 simpler.

[0066] Through the above arrangement, the existence of the knock-off tool hole 140 significantly reduces the complexity of the disassembly work, allowing the operator to complete the disassembly task with less effort and time. Such an arrangement not only improves work efficiency, but also reduces labor costs, while improving the convenience and reliability of the overall operation. Therefore, the ingenious arrangement of the knock-off tool hole 140 is an important detail in the arrangement of the easy-to-disassemble structure 120, which improves user needs and operational convenience.

[0067] Reference Figure 1 and Figure 2 As shown, in some examples, an avoidance gap 130 is opened on the wall surface of the accommodating through hole 110 away from the wiring assembly 200 , and the avoidance gap 130 is connected to the accommodating through hole 110 .

[0068] At least one avoidance notch 130 is provided on the wall of the receiving through hole 110 away from the wiring assembly 200. These avoidance notches 130 are connected with the receiving through hole 110. Such a setting allows electronic components such as the surge module 300 to be more conveniently placed in the receiving through hole 110 during installation. Such a structural layout not only optimizes the use efficiency of space, but also enhances the functionality of the entire wiring cover 100.

[0069] By directly cutting out the corresponding avoidance notch 130 on the wiring cover 100, the installation process of the electronic components becomes easier, and the reliability and stability of the overall device are also improved. This setting takes into account the convenience of actual operation and also reflects the efficient use of the internal space.

[0070] Reference Figure 3 and Figure 4 As shown, in some examples, the contactor further includes a surge module 300, which is connected to the wiring cover 100, and is disposed on a side of the wiring assembly 200 away from the accommodating through hole 110, and the surge module 300 partially protrudes from the outer surface of the contactor;

[0071] When two contactors are connected, the surge module 300 on one contactor can be plugged into the avoidance notch 130 on the other contactor. The avoidance notch 130 facilitates the insertion of the surge module 300 and other devices into the receiving through hole 110, thereby improving the utilization of space and reducing the width of the space when the two contactors are placed side by side.

[0072] The surge module 300 can protect the circuit and prevent the equipment from being damaged due to a sudden increase in current. The surge module 300 is tightly connected to the wiring cover 100 to ensure its stability and reliability.

[0073] During installation, the surge module 300 is placed on one side of the wiring assembly 200, which is away from the receiving through hole 110. Due to its arrangement, a portion of the surge module 300 protrudes from the outer surface of the contactor, which may have a certain impact on the overall appearance of the contactor, but this impact is negligible because it plays an important protective role.

[0074] When two contactors need to be connected together, the surge module 300 on one contactor can be easily inserted into the avoidance notch 130 on the other contactor. Such a setting not only allows the surge module 300 and other devices to be smoothly inserted into the receiving through hole 110, thereby improving the efficiency of space utilization, but also effectively reduces the width space of the two contactors when they are arranged side by side, which plays an important role in saving space and improving the compactness of the equipment.

[0075] The two contactors are arranged side by side to form a reversible contactor, which can have stronger performance.

[0076] Reference Figure 3 and Figure 4 As shown, in some examples, the surge module 300 includes a main body and an embedded part, the main body is connected to the wiring cover 100, the embedded part is arranged on a side of the main body away from the wiring cover 100, the embedded part protrudes from the outer surface of the contactor, and the embedded part can be embedded in the accommodating through hole 110 through the avoidance notch 130. The avoidance notch 130 facilitates the insertion of the embedded part of the surge module 300 into the accommodating through hole 110, thereby improving the utilization rate of the space.

[0077] The main body is connected to the wiring cover 100, ensuring the stability of the entire device. The embedded portion is arranged on the side of the main body away from the wiring assembly 200, and the embedded portion can protrude and be away from the wiring cover 100. Such a layout allows the embedded portion to protrude significantly from the outer surface of the contactor, thereby enhancing its protective function.

[0078] It is worth mentioning that the embedded part can be easily inserted into the receiving through hole 110 from the avoidance notch 130. The setting of the avoidance notch 130 not only enables the embedded part of the surge module 300 to be smoothly embedded into the receiving through hole 110, but also greatly improves the utilization rate of the space. In this way, the setting of the entire electronic device is more compact and the use efficiency is significantly improved.

[0079] In general, the configuration of the surge module 300 of the present application fully considers space utilization and protection effect.

[0080] Reference Figure 3 and Figure 4 As shown, in some examples, the contactor further includes a base 400 and a housing 500, the base 400 is connected to the housing 500, and the wiring cover 100 is covered on the housing 500. The above structure can make the installation and assembly of the contactor more stable and reliable. The base 400, the housing 500 and the wiring cover 100 can form a larger accommodating cavity, and various functional components of the contactor can be arranged in the accommodating cavity.

[0081] The structure of the base 400 and the housing 500 ensures the stability of the contactor as a whole. The housing 500 acts as an external protective layer, providing good protection for the internal components. In addition, the addition of the wiring cover 100 not only provides an upper cover for the contactor, but also makes the wiring operation more convenient, further improving the practicality of the contactor.

[0082] The above arrangement makes the installation and assembly process of the contactor more stable and reliable. Among the various components of the contactor, the base 400, the housing 500 and the wiring cover 100 together form a large accommodating cavity. This accommodating cavity provides a spacious installation space for various functional components of the contactor, making the internal layout of the contactor more reasonable, and various functional components can be effectively protected and fixed, thereby improving the overall performance of the contactor.

[0083] In the accommodating cavity, various functional components of the contactor can be arranged and installed in an orderly manner, which is not only conducive to improving the service life of the contactor, but also makes it more stable during operation. In general, this setting makes the contactor more reasonable in structure and more complete in function, providing users with a better use experience.

[0084] A through hole with a receiving function is set at the front end of the contactor. This innovative setting can effectively solve the problems that may arise when the wire is connected from the incoming terminal to the secondary circuit terminal of the contactor. Specifically, the wire may cross the front end of the contactor during the connection process and extend from the terminal of the outgoing terminal. This situation often causes the existence of the wire to affect the overall appearance of the contactor, which appears less coordinated. However, by setting a through hole at the front end of the contactor, not only can the wire be properly placed, avoiding messy wiring, but it can also keep the contactor neat and beautiful to a certain extent.

[0085] In addition, a knock-off feature is provided on one side wall of the accommodating through hole 110. This setting cleverly takes into account the compatibility issues when sharing space with other products, especially another product that may have a surge protrusion. When two contactors need to be installed side by side, it is usually necessary to consider the width space between them to ensure the rationality and stability of the installation. However, since a through hole with a knock-off feature is provided, the surge protrusion of another product can be effectively accommodated, which can reduce the space required when the two contactors are installed side by side to a certain extent, improve the efficiency of space utilization, and also bring convenience to installation.

[0086] In general, this setting not only improves the appearance quality of the contactor, making it more neat and orderly during the wiring process, but also optimizes the space occupied by the contactor, making it more flexible and efficient when sharing space with other products. This series of innovative settings undoubtedly improves the practicality and aesthetics of the contactor and further meets the needs of users.

[0087] In a second aspect, the present application provides an electrical device comprising at least one of the above-mentioned contactors.

[0088] The contactor described above in the present application can solve the problem of the connection wire being exposed to the outside of the contactor during connection. Specifically, the present application provides a specific receiving through hole 110 on the wiring cover 100. The receiving through hole 110 runs through the entire wiring cover 100, and the receiving through hole 110 is located on one side of the wiring assembly 200 as a whole, so that the connection wires of the secondary circuit input terminal 210 and the secondary circuit output terminal 220 can pass through this through hole. The need to wind the wires from the front end is avoided, and the front end of the contactor (the area where the wiring cover 100 is located) is effectively kept neat and beautiful. This not only improves the appearance quality of the equipment, but also improves the orderliness of the line connection, which helps to facilitate operation during maintenance and overhaul.

[0089] Electrical equipment may include equipment that can be applied to contactors, such as control systems in substations, smart home control systems such as elevators and air conditioners, and large railway systems such as trains and subways. Contactors in railway systems can be used for railway signal machines, locomotive control systems, etc., which are directly related to the travel speed, safety, and normal signal issuance of the transportation system.
