Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a contactor. Background Technology

[0002] A contactor is an electromagnetic automatic switching device, mainly used for frequently connecting or disconnecting AC / DC main circuits and high-capacity control circuits. It features large control capacity, high operating frequency, and reliable operation, and is widely used in industrial automation, power systems, building electrical systems, and other fields.

[0003] Contactors typically consist of a housing, a cover, and a base, with the housing and cover protecting the base. During installation, the housing and base are usually fitted together first, and then the cover and housing are fitted together last. This installation method complicates the contactor installation process, leading to higher manufacturing costs. Utility Model Content

[0004] This application provides a contactor to reduce the manufacturing cost of the contactor.

[0005] In a first aspect, this application provides a contactor comprising an integrated cover structure and a base. The integrated cover structure includes a top cover and a terminal cover. The top cover has an internal mounting space, and the terminal cover has an internal receiving cavity communicating with the mounting space. The side wall of the terminal cover has a slot. A portion of the base is located within the mounting space, and another portion of the base is located within the receiving cavity. A locking block is provided on the side wall of the base, with the locking block positioned opposite to the slot and located within the slot.

[0006] Through the above-described solution, the integrated cover structure eliminates the assembly steps between the top cover and the terminal cover using a single molding process. This reduces the contactor assembly process from multiple steps to a single step, thereby improving contactor production efficiency. The interlocking structure of the locking block and the locking slot reduces the possibility of vibration displacement of the base, thus reducing the possibility of relative displacement between the base and the integrated cover structure. The integrated cover structure avoids assembly errors of separate components, thereby reducing the need for multiple positioning during contactor assembly and saving labor costs in contactor production. Therefore, the contactor mentioned in this application can reduce both time and labor costs in production, thereby achieving the goal of reducing contactor manufacturing costs.

[0007] In one possible design, the slot extends through the side wall of the terminal cover. When the block engages with the slot, the block protrudes from the slot, and the side of the block away from the base is flush with the outer surface of the terminal cover.

[0008] Through the above-described design, the through-type structure of the slot allows the operator to visually observe the alignment of the locking block and the slot during the assembly of the integrated base and cover. When the locking block slides in along the installation direction of the integrated cover, the slot wall provides circumferential restraint, preventing lateral displacement of the base. The outer end face of the locking block is flush with the outer wall of the terminal cover; after being locked in place, the locking block will neither protrude outwards, compromising the flatness of the appearance, nor suffer from insufficient locking force due to excessive inward retraction. This structure, through the dual functions of mechanical limiting and surface flushing, simplifies the installation process while improving assembly reliability.

[0009] In one possible design, the locking block has a guide ramp on the side near the top cover in a first direction. The first direction is parallel to the mounting direction of the integrated cover structure towards the base, and the guide ramp provides guidance for the installation of the integrated cover structure.

[0010] Through the above-described solution, this application simplifies the complex three-dimensional alignment operation into a single-direction linear pressing action by coordinating the geometric features of the guide ramp of the locking block with the installation direction. This enables rapid assembly of the integrated cover structure and the base, reducing manual adjustment time and operational complexity. The automatic alignment function of the locking block and slot during the installation of the integrated cover structure and base reduces rework caused by assembly misalignment, improving the assembly efficiency of the production line. The coordinated design of the guide ramp and the installation direction effectively prevents structural interference during the locking process, reducing the risk of component damage.

[0011] In one possible design, the base is provided with a first terminal block and a second terminal block, the first terminal block being located inside a top cover and the second terminal block being located inside a terminal cover. The top cover has a first window for allowing an external conductive component to extend into the mounting space and connect to the first terminal block. The terminal cover has a second window for allowing an external conductive component to extend into the receiving cavity and connect to the second terminal block.

[0012] Through the above-described solution, this application utilizes a split-window design to create independent access channels for terminals with different functions. Conductive components achieve precise alignment under the constraints of their respective windows, eliminating human error during assembly. Furthermore, the split layout of the first and second windows allows for simultaneous wiring operations of the control circuit and the main circuit, avoiding the processing delays caused by traditional series wiring methods.

[0013] In one possible design, a first limiting rib is provided on the top cover near the first window. The first limiting rib abuts against the side wall of the first wiring terminal facing the first window.

[0014] With the above solution, when the contactor experiences shaking or impact during use, the first terminal may shift along the opening direction of the first window. The first limiting rib, through direct contact with the side wall of the first terminal, forms a physical constraint perpendicular to the displacement direction of the first terminal. Since the first limiting rib and the top cover are integrated, the rigid support of the limiting rib can also prevent the first terminal from shifting due to force during the insertion of the conductive component, thus improving the stability of the internal electrical connection of the contactor. At the same time, the integrated structure of the limiting rib and the top cover simplifies the assembly process and avoids the increased cost caused by adding independent limiting components.

[0015] In one possible design, the first limiting rib has a guide slope on the side near the terminal cover in the first direction.

[0016] Compared to existing technologies, traditional contactors typically use a vertical first limiting rib to directly block the terminal block, leading to interference between the first limiting rib and the base during assembly, potentially causing the limiting rib to break or the base to be improperly installed. This solution, however, adds a guide slope to the first limiting rib. This guide slope reduces the assembly resistance between the integrated cover structure and the base, decreasing the likelihood of damage to the limiting rib due to impact. Thus, while maintaining the limiting function for the first terminal block, it also optimizes the assembly path, thereby improving the contactor's assembly efficiency and structural reliability.

[0017] In one possible design, the terminal cover has a second limiting rib near the second window. The second limiting rib abuts against the side wall of the second terminal facing the second window.

[0018] Through the above-described solution, this application directly creates a physical limit on the second terminal by adding a second limiting rib at the second window. When the contactor experiences shaking or impact during use, the rigid blocking effect of the second limiting rib can reduce the occurrence of poor contact caused by lateral displacement of the second terminal, thereby ensuring the stability of the connection between the second terminal and the conductive component. Simultaneously, the integrated design of the second limiting rib and the terminal cover can reduce manufacturing costs without affecting the normal insertion and removal of the conductive component through the second window.

[0019] In one possible design, the second limiting rib has a guide slope at the end away from the top cover in the first direction.

[0020] Compared with existing technologies, the traditional contactor's second limiting rib uses a right-angle structure at its end, which can easily lead to a hard collision between the second terminal and the limiting rib during assembly, causing installation difficulties between the integrated cover structure and the base or deformation of the limiting rib. This solution, by setting a guide slope on the second limiting rib, can decompose the vertical assembly force into a lateral displacement component, thereby reducing the assembly resistance between the integrated cover structure and the base.

[0021] In one possible design, the inner wall of the integrated cover structure is reinforced with ribs.

[0022] Through the above solution, when the integrated cover structure is mounted on the base or subjected to external loads, the reinforcing ribs on the inner wall of the integrated cover structure can form an additional support network. By transferring the load to the extension direction of the reinforcing ribs, deformation caused by local stress concentration is avoided. This effectively improves the deformation resistance of the integrated cover structure, prevents cracking or installation misalignment caused by mechanical stress, and avoids increasing the overall volume of the integrated cover structure by adding external reinforcement structures, ensuring reliable operation of the contactor in a compact space.

[0023] In one possible design, there are multiple reinforcing ribs, which are arranged at equal intervals.

[0024] The above solution involves fabricating multiple equally spaced reinforcing ribs on the inner wall of the integrated cover structure. These ribs form a continuous support network through raised strip structures, evenly distributing external loads and internal assembly pressures. The consistent spacing of the multiple reinforcing ribs ensures uniform stress distribution in each area, reducing the risk of localized deformation due to stress differences. Simultaneously, the equally spaced arrangement avoids material redundancy while maintaining structural strength, reducing weight and manufacturing costs, and does not affect the installation space for internal components.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist.

[0037] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In existing technologies, contactors generally adopt a split cover structure, with the top cover and terminal cover needing to be assembled with the base separately. This structure results in a cumbersome installation process, requiring multiple positioning operations, and significantly increasing labor and time costs.

[0040] To address the aforementioned problems, this application provides a contactor. To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] Figure 1 This is a partial structural diagram of the contactor provided in an embodiment of this application. Figure 2 This is a schematic diagram of the integrated cover structure provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the base provided in an embodiment of this application. Figures 1 to 3As shown, the contactor provided in this application includes an integrated cover structure and a base 300. The integrated cover structure includes a top cover 100 and a terminal cover 200. The top cover 100 has an internal mounting space, and the terminal cover 200 has an internal receiving cavity that communicates with the mounting space. The side wall of the terminal cover 200 has a slot 210. Part of the base 300 is located within the mounting space, and another part of the base 300 is located within the receiving cavity. A locking block 310 is provided on the side wall of the base 300, and the locking block 310 is positioned opposite to the slot 210 and is located within the slot 210.

[0042] The integrated cover structure refers to the top cover 100 and the terminal cover 200 being formed into an inseparable whole component through injection molding. Specifically, it can be achieved by integral molding of polyamide material. The integrated cover structure can eliminate the assembly gap of separate components.

[0043] The installation space refers to the cavity structure formed inside the top cover 100, which can be used to accommodate the upper functional modules of the base 300. The receiving cavity refers to the extended cavity formed inside the terminal cover 200, which ensures that the lower part of the base 300 can be fully embedded.

[0044] The slot 210 refers to a recessed structure on the side wall of the terminal cover 200, and the opening direction of the slot 210 can be perpendicular to the mounting direction of the base 300. The locking block 310 refers to a protruding rectangular boss on the side wall of the base 300, which can be implemented by injection molding simultaneously with the main body of the base 300. The locking block 310 can form a clearance fit with the slot 210, or the locking block 310 can form an interference fit with the slot 210.

[0045] When the integrated cover structure is assembled with the base 300, the installation space inside the top cover 100 can form a continuous cavity with the receiving cavity inside the terminal cover 200 to guide the base 300 to be inserted in a single direction. During installation, the locking block 310 can slide along the outer wall of the terminal cover 200 until it aligns with the locking groove 210. At this point, axial pressure can cause the locking block 310 to embed into the locking groove 210, forming a mechanical interlock. This interlock structure can provide bidirectional constraint on the base 300 after it is inserted into place.

[0046] Compared to existing technologies, traditional contactors require separate installation of the top cover 100, terminal cover 200, and base 300. This solution achieves a single assembly operation through an integrated cover structure. Existing technologies rely on threaded fasteners to fix the base 300, while this solution uses a snap-fit ​​interlocking structure to eliminate the risk of bolt loosening. Traditional terminals are fixed only by the base 300 itself, while this solution creates dual constraints through the rigid connection between the base 300 and the cover.

[0047] Through the above technical solution, the integrated cover structure eliminates the assembly process between the top cover 100 and the terminal cover 200 by using an integral molding process. This reduces the contactor assembly process from multiple steps to a single step, thereby improving the contactor's production efficiency. The interlocking structure of the locking block 310 and the locking slot 210 reduces the possibility of vibration displacement of the base 300, thereby reducing the possibility of relative displacement between the base 300 and the integrated cover structure. The integrated cover structure avoids assembly errors of separate components, thereby reducing the need for multiple positioning during contactor assembly, which saves labor costs in contactor production. Therefore, the contactor mentioned in this application can reduce both time and labor costs in production, thus achieving the goal of reducing contactor manufacturing costs.

[0048] Furthermore, the integrated cover design eliminates the need for the original snap-fit ​​structure on the top cover 100, thereby increasing the arc-extinguishing space inside the contactor. When the arc-extinguishing space inside the contactor is increased, the heat dissipation efficiency of the arc during the disconnection process can be improved, and the rebound problem when the arc touches the snap-fit ​​structure can be avoided, thus improving the arc-extinguishing efficiency of the contactor.

[0049] Please continue to refer to Figures 1 to 3 As shown, the slot 210 mentioned in this application penetrates the side wall of the terminal cover 200. When the block 310 engages with the slot 210, the block 310 protrudes from the slot 210, and the side of the block 310 away from the base 300 is flush with the outer surface of the terminal cover 200.

[0050] The slot 210 penetrating the sidewall of the terminal cover 200 means that the slot 210 forms a through-hole structure in the thickness direction of the sidewall of the terminal cover 200. The slot 210 can be set on the terminal cover 200 by grooving or engraving after the cover is integrally formed, or the slot 210 can be integrally formed with the cover. The slot 210 structure penetrating the terminal cover 200 can provide a complete embedding path for the card block 310, ensuring the axial positioning accuracy of the base 300 and the cover integral structure during the engagement of the card block 310 and the slot 210.

[0051] The fact that the side of the locking block 310 furthest from the base 300 is flush with the outer surface of the terminal cover 200 means that the outer end face of the locking block 310 is on the same plane as the outer wall of the terminal cover 200 after the locking is completed. This design can eliminate unevenness on the surface of the terminal cover 200 after assembly and avoid assembly interference caused by local protrusions.

[0052] Through the above technical solution, during the assembly of the base 300 and the cover integrated structure, the through-type structure of the slot 210 allows the operator to intuitively observe the alignment status of the locking block 310 and the slot 210. When the locking block 310 slides in along the installation direction of the cover integrated structure, the groove wall of the slot 210 can form a circumferential constraint on the locking block 310, preventing the base 300 from shifting laterally. The outer end face of the locking block 310 is flush with the outer wall of the terminal cover 200. After being locked in place, the locking block 310 will neither protrude outward and damage the appearance flatness, nor will it suffer from insufficient locking force due to excessive inward shrinkage. This structure, through the dual effects of mechanical limiting and surface flushing, simplifies the installation process while improving assembly reliability.

[0053] Furthermore, to make the installation of the integrated cover structure even more convenient, please continue to refer to... Figures 1 to 3 As shown, the locking block 310 may have a guide slope on the side near the top cover 100 in the first direction. The first direction may be parallel to the mounting direction of the integrated cover structure towards the base 300. That is, the first direction may be the direction in which the integrated cover structure presses downwards along the axis of the base 300.

[0054] The locking block 310 can be a protruding structure provided on the side wall of the base 300. Specifically, it can be integrally formed with the base 300 using injection molding, or the locking block 310 can be set on the side wall of the base 300 by means of adhesion after the base 300 is formed. The locking block 310 can be used to form a mechanical lock with the locking groove 210 on the side wall of the terminal cover 200.

[0055] The guide slope can be an inclined surface on the side of the card block 310 near the top cover 100. The guide slope can be an inclined structure with an inclination angle of 30-45 degrees. The guide slope can be used to guide the contact between the card block 310 and the card slot 210 during installation.

[0056] When the integrated cover structure moves along the first direction, the guide ramp of the locking block 310 first contacts the side wall of the terminal cover 200. Sliding friction occurs between the guide ramp and the edge of the slot 210, forcing the integrated cover structure to generate lateral displacement compensation, causing the locking block 310 to automatically slide into the slot 210. Since the first direction is parallel to the installation direction, the inclination angle of the ramp and the downward pressure direction form a vector decomposition relationship, converting the vertical installation pressure into a lateral displacement driving force.

[0057] In existing technologies, the 310 locking block is mostly a right-angle structure, which is prone to jamming due to assembly deviations. However, this solution effectively eliminates positional errors during installation through a displacement compensation mechanism generated by inclined surface contact.

[0058] Through the above technical solution, this application simplifies the complex three-dimensional alignment operation into a single-direction linear pressing action by coordinating the geometric features of the guide slope of the locking block 310 with the installation direction. This enables rapid assembly of the integrated cover structure and the base 300, reducing manual adjustment time and operational complexity. The automatic alignment function of the locking block 310 and the locking slot 210 during the installation of the integrated cover structure and the base 300 reduces rework caused by assembly misalignment, improving the assembly efficiency of the production line. The coordinated design of the guide slope and the installation direction effectively prevents structural interference during the locking process, reducing the risk of component damage.

[0059] To improve the reliability of the contactor, this application also makes improvements to the internal structure of the integrated cover. In order to enable those skilled in the art to better understand the solution, the improvements to the internal structure of the integrated cover will be clearly and completely described below with reference to the accompanying drawings.

[0060] like Figure 1 as well as Figure 3 As shown, the base 300 is provided with a first terminal block 320 and a second terminal block 330. The first terminal block 320 is located inside the top cover 100, and the second terminal block 330 is located inside the terminal cover 200. The top cover 100 is provided with a first window 110 for allowing an external conductive component to extend into the mounting space and connect with the first terminal block 320. The terminal cover 200 is provided with a second window 220 for allowing an external conductive component to extend into the receiving cavity and connect with the second terminal block 330.

[0061] The first window 110 refers to a rectangular opening structure formed on the side wall of the top cover 100. Specifically, it can be achieved by forming a through groove on the side wall of the top cover 100 using a stamping process. The width of the first window 110 can be slightly larger than the cross-sectional dimensions of the external conductive component to constrain the insertion path of the conductive component. The second window 220 refers to a rectangular opening structure on the side wall of the terminal cover 200. Specifically, it can be achieved by forming a through groove on the side wall of the terminal cover 200 using a stamping process. The first terminal 320 refers to an alloy conductive sheet disposed in the top area of ​​the base 300. Specifically, it can be fixed to a preset mounting position on the base 300 by interference fit. The first terminal 320 can be used to connect external wires of the control circuit. The second terminal 330 refers to an alloy conductive sheet disposed in the bottom area of ​​the base 300. Specifically, it can be fixed to a preset mounting position on the base 300 by interference fit. The second terminal 330 can be used to connect external wires of the main circuit.

[0062] The mounting space of the top cover 100 and the receiving cavity of the terminal cover 200 form a continuous cavity through a through structure, and the main body of the base 300 is configured to be embedded in both cavities simultaneously. A first terminal 320 is arranged in the area covered by the top cover 100, directly facing the central axis of the first window 110. When an external conductive component is inserted along the opening direction of the first window 110, it can directly form surface contact with the contact surface of the first terminal 320. A second terminal 330 is arranged in the area covered by the terminal cover 200, directly facing the central axis of the second window 220. When an external conductive component is inserted along the opening direction of the second window 220, it can directly form surface contact with the contact surface of the second terminal 330. The opening directions of the first window 110 and the second window 220 form a spatially staggered layout, which avoids interference between conductive components during assembly.

[0063] Through the above technical solution, this application utilizes a split window design to create independent access channels for terminals with different functions. Conductive components achieve precise alignment under the constraints of their respective windows, eliminating human error during assembly. Furthermore, the split layout of the first window 110 and the second window 220 allows for simultaneous wiring operations of the control circuit and the main circuit, avoiding the processing delays caused by traditional series wiring methods.

[0064] Figure 4 for Figure 2 Enlarged view of section A. To improve the reliability of the first terminal block 320, such as... Figure 1 , Figure 3 as well as Figure 4 As shown, a first limiting rib 120 is provided on the top cover 100 near the first window 110. The first limiting rib 120 abuts against the side wall of the first terminal 320 facing the first window 110.

[0065] The first limiting rib 120 refers to a strip-shaped protrusion extending along the inner wall of the top cover 100. Specifically, it can be integrally processed with the top cover 100 using injection molding. The first limiting rib 120 can be used to form a rigid block against the movement of the first terminal 320.

[0066] Through the above technical solution, when the contactor experiences shaking or impact during use, the first terminal 320 may shift along the opening direction of the first window 110. The first limiting rib 120, through direct contact with the side wall of the first terminal 320, forms a physical constraint perpendicular to the displacement direction of the first terminal 320. Since the first limiting rib 120 and the top cover 100 are integrated, the rigid support of the limiting rib can also prevent the first terminal 320 from shifting due to force during the insertion of the conductive component, thus improving the stability of the internal electrical connection of the contactor. At the same time, the integrated structure of the limiting rib and the top cover 100 simplifies the assembly process and avoids the increased cost caused by adding independent limiting components.

[0067] Furthermore, please continue to refer to Figure 1 , Figure 3 as well as Figure 4 As shown, the first limiting rib 120 has a guide slope on the side near the terminal cover 200 in the first direction.

[0068] The guide slope refers to the inclined surface formed by the first limiting rib 120 on the side close to the terminal cover 200 in the first direction. Specifically, it can be formed by a mold forming process. The guide slope provided on the first limiting rib 120 can be used to guide the base 300 to slide into the installation space along a predetermined path.

[0069] Specifically, when the base 300 is assembled with the cover, the guide slope on the first limiting rib 120 can contact the edge of the first terminal 320, so that the base 300 is guided by the guide slope on the first limiting rib 120 during the movement, and gradually adjusted to the correct installation position.

[0070] Compared with existing technologies, traditional contactors typically use a vertical first limiting rib 120 to directly block the terminal block, causing interference between the first limiting rib 120 and the base 300 during assembly, potentially leading to rib breakage or improper installation of the base 300. This solution, however, adds a guide slope to the first limiting rib 120. This guide slope reduces the assembly resistance between the integrated cover structure and the base 300, decreasing the likelihood of damage to the limiting rib due to impact. Thus, while maintaining the limiting function for the first terminal block 320, the assembly path is optimized, thereby improving the contactor's assembly efficiency and structural reliability.

[0071] Figure 5 for Figure 2 Enlarged view of section B. To improve the reliability of the second terminal block 330, such as... Figure 1 , Figure 3 as well as Figure 5As shown, a second limiting rib 230 is provided on the terminal cover 200 near the second window 220. The second limiting rib 230 abuts against the side wall of the second wiring terminal 330 facing the second window 220.

[0072] The second limiting rib 230 refers to the protruding structure provided on the terminal cover 200 near the second window 220. Specifically, it can be manufactured integrally with the terminal cover 200 by injection molding. The height and thickness of the second limiting rib 230 can be adjusted according to the size of the second terminal 330. The second limiting rib 230 can form a rigid blocking effect on the second terminal 330.

[0073] Specifically, the second limiting rib 230 restricts the displacement of the second terminal 330 during contactor operation by abutting against the side wall of the second terminal 330. When an external conductive component is inserted into the receiving cavity through the second window 220, the contact surface between the second limiting rib 230 and the side wall of the second terminal 330 can form a rigid constraint to prevent vibration or external force from causing the terminal to shift.

[0074] Through the above technical solution, this application adds a second limiting rib 230 at the second window 220 to directly physically limit the second terminal 330. When the contactor shakes or bumps during use, the rigid blocking effect of the second limiting rib 230 can reduce the contact problems caused by lateral displacement of the second terminal 330, thereby ensuring the stability of the connection between the second terminal 330 and the conductive component. At the same time, the integrated design of the second limiting rib 230 and the terminal cover 200 can reduce manufacturing costs and does not affect the normal insertion and removal operation of the conductive component through the second window 220.

[0075] Furthermore, please continue to refer to Figure 1 , Figure 3 as well as Figure 5 As shown, the second limiting rib 230 has a guide slope at the end away from the top cover 100 in the first direction.

[0076] The guide slope of the second limiting rib 230 means that the side wall of the second limiting rib 230 away from the top cover 100 can be designed as an inclined surface. Specifically, it can be achieved by forming an inclined angle of 30°-60° with the end of the second limiting rib 230. The setting of the second limiting rib 230 can be used to guide the contact trajectory between the second wiring terminal 330 and the terminal cover 200 during the assembly process.

[0077] Specifically, when the base 300 is assembled with the cover as an integral structure, the guide slope on the second limiting rib 230 can contact the edge of the second terminal 330, so that the base 300 is guided by the guide slope on the second limiting rib 230 during the movement, and gradually adjusted to the correct installation position.

[0078] Compared with existing technologies, the traditional contactor's second limiting rib 230 has a right-angled end, which can easily cause the second terminal 330 to collide with the limiting rib during assembly, resulting in installation difficulties between the integrated cover structure and the base 300 or deformation of the limiting rib. This solution, by setting a guide slope on the second limiting rib 230, can decompose the vertical assembly force into a lateral displacement component, thereby reducing the assembly resistance between the integrated cover structure and the base 300.

[0079] To improve the reliability of the integrated cover structure, such as Figures 1 to 3 As shown, the inner wall of the integrated cover structure mentioned in this application is also provided with reinforcing ribs.

[0080] The integrated cover structure has been described above and will not be repeated here.

[0081] Reinforcing ribs refer to protruding structures set along the inner wall of the integrated cover structure. Specifically, they can be made of the same material as the integrated cover structure and be in the form of strip protrusions. The setting of reinforcing ribs can improve the bending resistance of the integrated cover structure by increasing the moment of inertia of the cross section of the inner wall of the integrated cover structure.

[0082] During the installation of the base 300, the compressive force generated by the contact between the base 300 and the inner wall of the cover can be dispersed to the entire structure of the cover through the reinforcing ribs, rather than acting only on a single contact point. At the same time, when the reinforcing ribs are distributed along the inner wall, their orientation can be optimized according to the stress distribution law. For example, annular reinforcing ribs can be set in the connection transition area between the terminal cover 200 and the top cover 100 to cope with the shear stress caused by the structural abrupt change in this area.

[0083] Compared to existing technologies, traditional contactor covers employ a split structure without internal reinforcement, making them prone to deformation or seam cracking under mechanical loads. This solution, through the synergistic effect of an integrated cover and built-in reinforcing ribs, achieves higher structural stability while maintaining the original assembly functionality and keeping the cover thickness constant.

[0084] In summary, when the integrated cover structure is mounted on the base 300 or subjected to external loads, the reinforcing ribs on the inner wall of the integrated cover structure form an additional support network. By transferring the load to the extension direction of the reinforcing ribs, deformation caused by localized stress concentration is avoided. This effectively improves the deformation resistance of the integrated cover structure, preventing cracking or misalignment due to mechanical stress. It also avoids increasing the overall volume of the integrated cover structure by adding external reinforcement, ensuring reliable operation of the contactor within a compact space.

[0085] Furthermore, please continue to refer to Figures 1 to 3As shown, there can be multiple reinforcing ribs mentioned in this application, and the multiple reinforcing ribs can be arranged at equal intervals.

[0086] Equal spacing means that multiple reinforcing ribs are distributed at the same intervals along the inner wall of the integrated cover structure in the circumferential or axial direction. Specifically, it can be achieved by uniform arrangement design. The balanced layout avoids local stress concentration and maintains the overall rigidity of the structure.

[0087] Through the above configuration, multiple equally spaced reinforcing ribs are machined on the inner wall of the integrated cover structure. These ribs form a continuous support network through raised strip structures, evenly distributing external loads and internal assembly pressures. The consistent spacing of the multiple reinforcing ribs ensures uniform stress distribution in each area, reducing the risk of localized deformation due to stress differences. Simultaneously, the equally spaced arrangement avoids material redundancy while maintaining structural strength, reducing weight and manufacturing costs, and does not affect the installation space for internal components.
