Description

Technical Field

[0001] The present application relates to the technical field of electrical connection devices, and in particular to a guide rail block of a contactor and a contactor. Background Art

[0002] Contactors are electrical devices widely used in power generation, distribution, and consumption. Their core function is to generate a magnetic field by controlling the current in a coil, which in turn drives the contacts to close or open, thereby controlling the load. The contactor's mounting method has a significant impact on its performance and maintenance. Traditional contactors typically use a flat-panel mounting structure, requiring screws to secure the contactor to a flat surface. With technological advancements, contactor installation has become more modular, with the emergence of two primary mounting methods: rail-mounted and screw-mounted. Rail-mounted mounting is suitable for lighter products, while screw-mounted mounting is suitable for heavier products. For moderately heavy products, such as certain AC contactors, rail-mounted or screw-mounted mounting can be selected depending on the operating conditions. In environments with high vibration, screw-mounted mounting is often preferred for stability and safety.

[0003] However, the guide rail block of the contactor base in the prior art protrudes from the contactor body, thereby increasing the overall volume and packaging cost. In addition, the protruding portion of the body is easily bumped during transportation, causing damage to the guide rail block. Utility Model Content

[0004] The present application provides a guide rail block of a contactor and a contactor, so as to solve the problem that the guide rail block of a contactor base needs to protrude from the contactor body, thereby reducing the overall volume of the contactor, lowering packaging costs, and improving transportation safety.

[0005] In the first aspect, the present application provides a guide rail block of a contactor, which is installed on a contactor base, and the contactor base has a mounting guide rail. The guide rail block includes: a block body, the block body can be fixedly connected to the contactor base, the block body has a first surface in contact with the contactor base, and when the block body is installed on the contactor base, it has a first end facing the mounting guide rail and a second end facing the edge of the contactor base, and the second end does not exceed the edge of the contactor base; a boss structure, the boss structure is a protrusion provided on the second surface of the block body, and the second surface is a surface on the block body opposite to the first surface; the boss structure has a table parallel to the second surface and a support structure connected between the second surface and the table, and the table has an open groove, the open groove is suitable for the screw head to enter the interior of the boss structure and can clamp the main screw head.

[0006] Through the above solution, the design of the boss structure enables the guide rail block to have the function of installing screws, and the guide rail block will not extend out of the edge of the contactor base, which means that the guide rail block does not protrude from the body of the contactor, effectively reducing the overall volume and reducing the packaging cost. In addition, since the guide rail block does not protrude from the body, the risk of damage during transportation is reduced, thereby improving the reliability and durability of the product.

[0007] In one possible design, the open slot extends from the center of the table top to the edge of the table top, and the screw head can enter from the edge of the table top and slide into the open slot.

[0008] With this solution, the open slot design allows the screw head to enter from the edge, making the screw installation process more intuitive and convenient, reducing the need for precise alignment. The screw can slide directly into the open slot, which speeds up assembly and improves installation efficiency. The open slot design can conceal the screw head within the boss structure, providing a cleaner and more aesthetically pleasing appearance. This design provides greater flexibility, allowing the use of screws of different lengths and diameters to accommodate different installation requirements.

[0009] In a possible design, a chamfered structure is provided at a starting end of the open slot for the screw head to slide into.

[0010] With this solution, the chamfered structure acts as a guide, making it easier for the screw to align and slide into the slot, reducing installation difficulty and time, and helping to ensure the screw is correctly positioned during installation, improving assembly accuracy. The chamfered structure also facilitates screw removal, making the process smoother. Furthermore, the chamfered structure reduces direct impact between the screw head and the contactor body, reducing the risk of component damage caused by misoperation during installation.

[0011] In a possible design, the edge of the table located on the side where the second end of the card block body is located is the first edge, the open groove extends from the center of the table to the first edge, and the area between the first edge and the card block body is hollowed out.

[0012] Through the above solution, the edge of the table on the side where the second end is located is the first edge, so that the head of the screw can enter from the first edge on the side where the second end of the block body is located, and the space between the first edge and the block body is hollowed out. The hollow design allows sufficient edge space at the starting end for the screw to slide in, so that the screw can slide into the open slot more quickly and accurately from the edge, reducing the requirement for precise positioning of the screw head, thereby reducing the possibility of errors during the installation process. The simplified assembly process can reduce assembly time and improve overall work efficiency. The hollow design provides sufficient space so that the operator can easily pass the operating tool through the hollow and contact the screw head for installation and fixation of the screw. The hollow design allows the operator to directly see the position of the screw head, which helps to ensure that the screw is correctly installed in the intended position.

[0013] In one possible design, the guide rail block also includes a horizontal bar structure, which is arranged on the block body or the boss structure. There is a gap between the horizontal bar structure and the block body or the boss structure, and the gap is suitable for an operating tool to pass through to pry the guide rail block to move.

[0014] The combination of the horizontal bar and the gap provides a clear guide for installers on how to correctly move and position the rail clips, reducing installation errors. The gap between the horizontal bar and the clip body or boss allows the use of an operating tool (such as a screwdriver) to pry the rail clips, making their movement and positioning easier and faster.

[0015] In one possible design, a first hollow window is provided on the card block body, and the first hollow window extends from the first surface to the second surface of the card block body, the boss structure is located at a position corresponding to the first hollow window, and the cross-bar structure is provided at the second end of the card block body, or the cross-bar structure is provided on one side of the boss structure at the second end; the position of the contactor base corresponding to the cross-bar structure has a recessed structure, and a screwdriver can be inserted into the gap between the cross-bar structure and the card block body or the boss structure, and the edge of the contactor base at the recessed structure is used as a support point to pry the guide rail card block to move.

[0016] Through the above solution, the boss structure is set at the position of the first hollow window, the horizontal bar structure is set at the second end of the card block body, and the bottom of the contactor at the corresponding position is a recessed structure. In this way, the space between the recessed structure and the boss structure and the horizontal bar structure is large enough. When a screwdriver is inserted from the gap between the horizontal bar structure and the card block body or the boss structure, the edge of the contactor base at the recessed structure can be used as a support point to pry the guide rail card block to move. At the same time, the distance between the edge of the recessed structure and the horizontal bar structure is short, which also makes the torque shorter. This makes it more labor-saving and convenient to use tools such as screwdrivers to pry the guide rail card block. The recessed structure provides a stable support point, making the action of prying the guide rail card block faster and more accurate, thereby improving work efficiency.

[0017] In a second aspect, the present application provides a contactor, comprising a contactor base and a guide rail block according to any one of the above claims, wherein the contactor base has a mounting guide rail, and the guide rail block is fixedly connected to the contactor base, with one end of the guide rail block facing the mounting base and the other end facing the edge of the contactor base and not exceeding the edge of the contactor base.

[0018] The beneficial effects of the contactor provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, and will not be repeated here.

[0019] In one possible design, a card track structure is provided on the contactor base to cooperate with the extension of the card block body. The card track structure includes a slide located on the contactor base and a buckle connected to the slide. The card block body can slide along the slide and be restricted in the card track by the buckle.

[0020] The above-mentioned design of the guideway and clip provides precise guidance, ensuring that the main block slides correctly along the predetermined path, improving the accuracy of guide rail clip installation. The clip limits the position of the main block within the guideway, enhancing the stability and reliability of the overall structure. The clip prevents the main block from accidentally falling off during use, simplifies the installation process, and reduces the need for accessories, helping to reduce product manufacturing and maintenance costs.

[0021] In one possible design, it also includes a clamping rod; a retaining wall is also provided on the contactor base, and the retaining wall protrudes from the surface of the contactor base; a first clamping structure is provided on the second surface of the block body, the first clamping structure includes a resisting portion and a hook portion connected to the resisting portion, and there is an accommodating space between the hook portion and the second surface. When the block body slides along the slide and is restricted in the slide by the buckle, the clamping rod can be partially clamped into the accommodating space. In the length direction of the slide, one side of the clamping rod abuts against the retaining wall, and the other side abuts against the resisting portion to limit the position of the guide rail block.

[0022] With the above solution, the connecting rod is inserted into the first connecting structure perpendicular to the length of the slideway. The first connecting structure is located between the retaining wall and the stop portion. The connecting rod can be partially inserted into the accommodating space. Along the length of the slideway, one side of the connecting rod abuts the retaining wall, and the other side abuts the stop portion. This is equivalent to the stop portion applying a force to the connecting rod away from the mounting rail, while the retaining wall applies a force to the connecting rod toward the mounting rail. The action of these two forces ensures that the guide rail block is firmly fixed to the contactor base by the connecting rod.

[0023] In one possible design, a second snap-fitting structure is provided on the first end of the block body. When the block body slides along the slideway and is restrained in the slideway by the buckle, the second snap-fitting structure can extend into one side of the mounting rail.

[0024] Through the above solution, the second clamping structure can be tightly matched with one side of the mounting rail to provide stable positioning and support for the contactor. When the contactor is installed on the external plane by means of a guide rail, it is necessary to pry the guide rail block in the direction away from the mounting rail so that the second clamping structure leaves the mounting rail to avoid the second clamping structure blocking the guide rail system on the external plane from sliding into the mounting rail for installation during installation. After the guide rail system on the external plane slides into the mounting rail for installation, the second clamping structure can tightly press against the guide rail system on the external plane under the action of the rebound force of the clamping connecting rod, so that the guide rail system on the external plane is more firmly installed on the mounting rail, ensuring stable installation of the contactor. The above description is only an overview of the technical solution of the embodiment of the present application. In order to more clearly understand the technical means of the embodiment of the present application, it can be implemented in accordance with the contents of the specification, and in order to make the above and other purposes, features and advantages of the embodiment of the present application more obvious and easy to understand, the specific implementation method of the present application is specifically cited below.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists, A and B exist, and B exists. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0037] The directional words appearing in the following description are all directions shown in the drawings, and do not limit the specific structure of the guide rail block of this application.

[0040] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, "connected" or "connected" in a mechanical structure can refer to a physical connection. For example, a physical connection can be a fixed connection, such as a fixed connection via a barrier, such as a screw, bolt, or other barrier. A physical connection can also be a removable connection, such as a snap-fit ​​connection.

It can also refer to internal communication between two components. A signal connection can refer not only to signal connection through an electrical circuit, but also to signal connection through a media medium, such as radio waves. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] Among electrical components, components that can be mounted along a guide rail typically include various sensors, actuators, contactors, relays, switches, and other control components. These components are designed to be easily slid or fixed along a guide rail (such as a DIN rail) for easy installation and maintenance. DIN rails are standardized metal tracks used to mount electrical components in control cabinets and racks. They help ensure consistency and compatibility between components.

[0042] When installing a contactor, in addition to rail-mounted mounting, screw-mounted mounting is also possible. A rail block is typically installed on the contactor base. When the mounting rail on the contactor base is assembled onto the rail system on an external surface, the rail block can press against or lock onto the rail system on the external surface, making the contactor installation more secure. Furthermore, positioning holes for screw mounting are designed on the rail block to facilitate screw-mounted mounting.

[0043] The guide rail blocks used in the contactors of the related art protrude from the contactor body, which increases the overall volume of the contactor and the packaging cost. In addition, the protruding parts of the contactor body are easily bumped during transportation, causing damage to the guide rail blocks.

[0044] In view of this, an embodiment of the present application provides a guide rail block of a contactor and a contactor, in which the guide rail block does not protrude from the contactor body, thereby effectively reducing the overall volume of the contactor and reducing packaging costs. Moreover, since the guide rail block does not protrude from the body, the risk of damage due to bumps during transportation is reduced, thereby improving the reliability and durability of the product.

[0045] Figure 1 This is a schematic diagram of the guide rail block provided in an embodiment of the present application from a first perspective. Figure 2 for Figure 1 A schematic diagram of the guide rail block from the first perspective is provided. Figure 3 This is a schematic diagram of the first perspective of the guide rail block provided in the embodiment of the present application installed on the contactor base. Figure 1 、 Figure 2 and Figure 3 The present application provides a guide rail block for a contactor, which is used to be installed on a contactor base 10. The contactor base 10 has a mounting rail 20, which can be installed in conjunction with a rail system on an external plane.

[0046] When the mounting guide rail 20 and the guide rail system on the external plane are mounted in coordination, the guide rail clamping block can clamp the guide rail system on the external plane, so that the contactor is mounted more firmly.

[0047] The guide rail block includes a block body 100 and a boss structure 200. The block body 100 can be fixedly connected to the contactor base 10. The block body 100 has a first surface that contacts the contactor base 10. When installed on the contactor base 10, the block body 100 has a first end facing the mounting guide rail 20 and a second end facing the edge of the contactor base 10, with the second end not extending beyond the edge of the contactor base 10. The boss structure 200 is a protrusion provided on the second surface of the block body 100. The second surface is the surface of the block body 100 that faces away from the first surface. The boss structure 200 has a table 220 parallel to the second surface and a support structure 210 connected between the second surface and the table 220. The table 220 has an open slot 221. The open slot 221 is suitable for the screw head to enter the interior of the boss structure 200 and can retain the screw head.

[0048] The design of the boss structure 200 in this embodiment enables the guide rail block to have the function of installing screws, and the guide rail block does not extend out of the edge of the contactor base 10, which means that the guide rail block does not protrude from the body of the contactor, effectively reducing the overall volume and reducing the packaging cost. In addition, since the guide rail block does not protrude from the body, the risk of damage during transportation is reduced, thereby improving the reliability and durability of the product.

[0049] The support structure 210 can be any structure that can connect the second surface and the table 220 and support the table 220. For example, it can be a planar structure connected between the second surface and the table 220, or a grid structure connected between the second surface and the table 220.

[0050] The shape of the opening slot 221 can be to include a first hole and a second hole, the first hole and the second hole are connected, the diameter of the first hole is larger than the diameter of the second hole, so that the first hole can allow the head of the screw to enter, and the second hole can only allow the rod of the screw to pass through, so that the head of the screw can be stuck inside the boss structure 200. When using a screw-type installation, the tip of a partial length screw can be screwed into the installation position on the corresponding external plane, and then the head of the screw can be inserted from the first hole, and then the screw can be slid into the second hole, and finally the screw can be rotated to fasten the screw to the external plane.

[0051] In this embodiment, the open slot 221 extends from the center of the table top 220 to the edge of the table top 220, and the screw head can enter from the edge of the table top 220 and slide into the open slot 221. The design of the open slot 221 allows the screw head to enter from the edge, making the screw installation process more intuitive and convenient, and reducing the requirement for precise alignment. The screw can slide directly into the open slot 221, which speeds up assembly and improves installation efficiency. The design of the open slot 221 can hide the screw head inside the boss structure 200, providing a neater and more beautiful appearance. This design provides more flexibility, allowing the use of screws of different lengths and diameters to adapt to different installation requirements.

[0052] In this embodiment, a chamfered structure 212 is provided at the starting end of the opening slot 221 for the screw head to slide into.

[0053] The chamfered structure 212 is provided at the starting end where the screw head slides in. The wall of the opening groove 221 with the chamfered structure has a small wall thickness near the starting end. As it moves away from the starting end, the thickness of the wall of the opening groove 221 with the chamfered structure gradually increases. In this way, the chamfered structure 212 can serve as a guide, making it easier for the screw to align and slide into the opening groove 221, reducing the difficulty and time during installation, and helping to ensure that the screw is in the correct position during installation, thereby improving the accuracy of assembly. When the screw needs to be removed, the chamfered structure 212 also provides convenience, making the disassembly process smoother. At the same time, the chamfered structure 212 can also reduce the direct collision between the screw head and the contactor body, reducing the risk of component damage due to misoperation during installation.

[0054] Figure 4 A schematic diagram showing a second perspective of the guide rail block provided in an embodiment of the present application being installed on a contactor base. Figure 5 This is a schematic diagram of a third perspective of the guide rail block provided in the embodiment of the present application being installed on the contactor base. Figure 3 、 Figure 4 and Figure 5 The edge of the table 220 located on the side of the second end of the card block body 100 is the first edge, the opening groove 221 extends from the center of the table 220 to the first edge, and the space between the first edge and the card block body 100 is hollow.

[0055] In this embodiment, the edge of the table on the side where the second end is located is the first edge, and the space between the first edge and the block body 100 is hollowed out. The hollow design allows sufficient edge space at the starting end for the screw to slide in, so that the screw can slide into the open slot 221 more quickly and accurately from the edge, reducing the requirement for precise positioning of the screw head, thereby reducing the possibility of errors during installation. The simplified assembly process can reduce assembly time and improve overall work efficiency. The hollow design provides sufficient space so that the operator can easily pass the operating tool through and contact the screw head, thereby facilitating the installation and fixation of the screw. The operating tool can be a screwdriver. The hollow design allows the operator to directly see the position of the screw head, which helps to ensure that the screw is correctly installed in the intended position. Please continue to refer to Figure 1 、 Figure 2 and Figure 3 In this embodiment, the guide rail block also includes a horizontal bar structure 300, which is arranged on the block body 100 or the boss structure 200. There is a gap 301 between the horizontal bar structure 300 and the block body 100 or the boss structure 200. The gap 301 is suitable for an operating tool to pass through it to pry the guide rail block to move.

[0056] The combination of the horizontal bar structure 300 and the gap 301 provides a clear guide for the installer on how to correctly move and position the guide rail block, reducing errors during installation. The gap 301 between the horizontal bar structure 300 and the block body 100 or the boss structure 200 allows the use of an operating tool (such as a screwdriver) to pry the guide rail block, making the block's movement and positioning more convenient and quick.

[0057] The horizontal bar structure 300 can be located at any position on the guide rail block as long as it helps to pry the guide rail block.

[0058] In this embodiment, in order to cooperate with the original design of the contactor base 10 while making it easier for users to operate, a first hollow window 111 is provided on the card block body 100, and the first hollow window 111 extends from the first side of the card block body 100 to the second side. The boss structure 200 is located at a position corresponding to the first hollow window 111, and the cross-bar structure 300 is provided at the second end of the card block body 100, or the cross-bar structure 300 is provided on one side of the boss structure 200 located at the second end; a recessed structure 30 is provided at a position of the contactor base 10 corresponding to the cross-bar structure 300, and a screwdriver can be inserted into the gap 301 between the cross-bar structure 300 and the card block body 100 or the boss structure 200, and use the edge of the contactor base 10 at the recessed structure 30 as a support point to pry the guide rail card block to move.

[0059] Through the above scheme, the boss structure 200 is arranged at the position of the first hollow window 111. Since the first hollow window 111 passes through the first surface of the block body 100 to the second surface, after the guide rail block is installed on the contactor base, the operator can use a tool to pass through the open slot 221 to operate the screws on the contactor base, thereby improving the convenience of operation.

[0060] The horizontal bar structure 300 is disposed at the second end of the block body 100, and the bottom of the contactor at the corresponding position is a recessed structure 30. This allows for sufficient space between the recessed structure 30, the internal space within the boss structure, and the horizontal bar structure 300. When a screwdriver is inserted through the gap 301 between the horizontal bar structure 300 and the block body 100 or the boss structure 200, the guide rail block can be pried and moved using the edge of the contactor base 10 at the recessed structure 30 as a support point. Furthermore, the short distance between the edge of the recessed structure 30 and the horizontal bar structure 300 also reduces the torque, making it easier and more convenient to pry the guide rail block with a tool such as a screwdriver. The recessed structure 30 provides a stable support point, making the action of prying the guide rail block faster and more accurate, thereby improving work efficiency.

[0061] Please refer to Figure 3 and Figure 4 An embodiment of the present application also provides a contactor, including a contactor base 10 and a guide rail block in any of the above embodiments, wherein the contactor base 10 has a mounting guide rail 20, and the guide rail block is fixedly connected to the contactor base 10, with one end of the guide rail block facing the mounting base and the other end facing the edge of the contactor base 10 and not exceeding the edge of the contactor base 10.

[0062] Since the structure and beneficial effects of the guide rail block have been described in detail in the previous embodiments, this application will not repeat them here. Figure 3 The contactor base 10 is provided with a card channel structure for the card block body 100 to extend into. The card channel structure includes a slideway located on the contactor base 10 and a buckle connected to the slideway. The card block body 100 can slide in along the slideway and be restricted in the card channel by the buckle.

[0063] Through the above solution, the design of the slideway and clip provides precise guidance for the block body 100, ensuring that the block body 100 slides correctly along the predetermined path, thereby improving the accuracy of the installation of the block body 100. The clip restrains the block body 100 within the track structure, enhancing the stability of the contactor's overall structure. The clip ensures that the block body 100 does not accidentally fall off during use and simplifies the installation process of the block body 100, helping to reduce the manufacturing and maintenance costs of the contactor.

[0064] Please refer to Figure 3 and Figure 4The guide rail block also includes a connecting rod 400, and a retaining wall 21 is further provided on the contactor base 10, which protrudes from the surface of the contactor base 10; a first connecting structure 110 is provided on the second surface, and the first connecting structure 110 includes a retaining wall 21 and a resisting portion connected to the retaining wall 21, and there is an accommodating space between the hook portion and the second surface. When the block main body 100 slides in along the slide and is restricted in the slide by the buckle, the connecting rod 400 can be partially inserted into the accommodating space.

[0065] Please refer to Figure 3 and Figure 4 , wherein the length direction of the slide is the first direction X, and the length direction perpendicular to the slide is the second direction Y. In the first direction X, one side of the connecting rod abuts against the retaining wall 21, and the other side abuts against the stopper to limit the position of the guide rail block.

[0066] Through the above solution, the clamping link 400 is clamped into the first clamping structure 110 along the second direction Y. The first clamping structure 110 is located between the retaining wall 21 and the resisting portion. The clamping link 400 can be partially clamped into the accommodating space. In the first direction X, one side of the clamping link abuts the retaining wall 21, and the other side abuts the resisting portion. In this way, the resisting portion applies a force to the clamping link away from the mounting rail, while the retaining wall 21 applies a force to the clamping link toward the mounting rail. The action of these two forces ensures that the guide rail clamping block is firmly clamped to the contactor base by the clamping link.

[0067] The connecting rod 400 can be made of stainless steel and can be cylindrical or prism-shaped.

[0068] Please refer to Figure 3 and Figure 4 The first clamping structure is located in the middle area of ​​the clamping connecting rod, and the retaining wall 21 is located at both ends of the clamping connecting rod, so that when the clamping connecting rod 400 is clamped into the first clamping structure 110, the clamping connecting rod 400 is subjected to a more balanced force, thereby better preventing the guide rail block from falling off the contactor base 10.

[0069] Please continue to refer to Figure 1 and Figure 2 In this embodiment, a second hollow window 112 is formed on the block body 100 located at the first clamping structure 110, and then the first clamping structure 110 is arranged on both sides of the second hollow window 112. Forming the second hollow window 112 first can make it easier to weld and process the first clamping structure 110.

[0070] Since the connecting rod 400 is stuck between the retaining wall 21 and the resisting part, when the guide rail block is pried away from the first direction X and moves away from the installation guide rail 20, the connecting rod 400 will not move but will be deformed accordingly. Therefore, the connecting rod 400 has a rebound force on the guide rail block, and the rebound force can squeeze the guide rail block toward the installation guide rail 20.

[0071] In this embodiment, a second clamping structure 120 is provided on the first end of the block body 100. When the block body 100 slides into the slide along the first direction X and is clamped and restricted in the slide, the second clamping structure 120 can extend to one side of the mounting rail 20.

[0072] In its natural state, the second engaging structure 120 extends into one side of the mounting rail 20. When the contactor is mounted on an external surface via the rail, the rail clamping block needs to be pried away from the mounting rail 20 to allow the second engaging structure 120 to separate from the mounting rail 20. This prevents the second engaging structure 120 from obstructing the guide rail system on the external surface from sliding into the mounting rail 20 during installation. After the guide rail system on the external surface is slid into the mounting rail 20 for installation, the second engaging structure 120, under the action of the rebound force of the engaging link 400, can tightly press against the guide rail system on the external surface, allowing the guide rail system on the external surface to be more securely mounted on the mounting rail 20 and ensuring stable installation of the contactor.
