Description

Technical Field

[0001] This application relates to the technical field of electrical connection devices, and particularly to a mounting structure for a thermal relay. Background Art

[0002] A thermal relay is a protection device used to protect motors and other electrical equipment from damage caused by overload current. In some cases, a thermal relay can be installed in combination with a contactor. In other cases, the thermal relay cannot be installed in combination with the contactor and needs to be installed separately.

[0003] The existing structures for the separate installation of thermal relays are relatively complex, with a large number of parts and cumbersome assembly. Summary of the Utility Model

[0004] This application provides a mounting structure for a thermal relay, which can solve the problems of the complex composition and cumbersome assembly of the existing thermal relay mounting structures, reduce the assembly difficulty of the thermal relay, and improve the assembly efficiency.

[0005] The technical solution of this application is as follows:

[0006] The mounting structure for a thermal relay provided by this application includes a mounting plate, a first buckle, a first set of mounting holes, and a second set of mounting holes. Among them, the mounting plate has a first side for mounting the thermal relay. The first buckle is connected to the first side of the mounting plate and is used to insert into the card slot of the thermal relay. The first set of mounting holes is provided on the mounting plate for fixedly connecting the mounting plate and the thermal relay. The second set of mounting holes is provided on the mounting plate for fixedly connecting the mounting plate and the equipment.

[0007] Through the mounting structure for a thermal relay provided by this application, the thermal relay can be mounted on the equipment. Moreover, the mounting structure for a thermal relay of this application only includes a mounting plate, a first buckle, a first set of mounting holes, and a second set of mounting holes, and has the characteristics of simple composition structure and convenient use, which can improve the installation efficiency of the thermal relay.

[0008] In one design, the mounting structure for a thermal relay further includes a rail mounting component, and the rail mounting component is arranged on the second side of the mounting plate. The second side is opposite to the first side and is the side of the mounting plate close to the equipment.

[0009] Based on the mounting structure for a thermal relay provided by this embodiment, the mounting structure for a thermal relay can be installed with other equipment without a rail through the second set of mounting holes, or can be assembled with equipment with a rail through the rail mounting component. In this way, the applicability of the mounting structure for a thermal relay of this application can be enhanced.

[0010] In a design, the guide rail mounting assembly includes a second buckle and a third buckle. The second buckle is a fixed buckle, and the third buckle is an elastic buckle. The second buckle and the third buckle are oppositely arranged on the mounting plate along a first direction. The third buckle has an elastic telescopic amount along the first direction relative to the second buckle. The second buckle, the third buckle and the mounting plate form a guide rail mounting groove.

[0011] Based on the thermal relay mounting structure provided by this embodiment, the thermal relay mounting structure of the present application includes a guide rail mounting assembly composed of a second buckle and a third buckle. Through this guide rail mounting assembly, the thermal relay can be conveniently clamped or disassembled with the guide rail, and the composition of the guide rail mounting assembly is simple and easy to implement.

[0012] In a design, the third buckle includes a slider, an elastic member and a mounting seat. The mounting seat is connected to the mounting plate, and the mounting seat has a positioning post facing the second buckle. The slider is provided with a third mounting hole and a fourth mounting hole that communicate with each other. The slider is arranged at the mounting plate of the mounting seat, and the slider is slidably connected to the mounting plate. The mounting seat passes through the third mounting hole, and the positioning post is inserted into the fourth mounting hole. One end of the elastic member is limited by the positioning post, and the other end of the elastic member abuts against the hole wall of the fourth mounting hole. The slider can have a telescopic amount along the first direction by relying on the elastic member.

[0013] Based on the thermal relay mounting structure provided by this embodiment, the third buckle is composed of a slider, an elastic member and a mounting seat. Through the third buckle, the thermal relay can be stably clamped to the guide rail, and the composition of the third buckle is simple and easy to implement.

[0014] In a design, one end of the slider facing the second buckle is further provided with a guiding inclined surface for facilitating the insertion of the guide rail.

[0015] Based on the thermal relay mounting structure provided by this embodiment, when the thermal relay is assembled with the guide rail through the thermal relay mounting structure, the thermal relay can be first hooked to the guide rail through the second buckle. Then, press the thermal relay to make the guide rail slide into the guide rail mounting groove along the inclined surface. In this way, the installation process is very simple and labor-saving.

[0016] In a design, the guide rail mounting assembly further includes a first hook and a second hook. The first hook has a first limiting surface facing the slider, and the second hook has a second limiting surface facing the slider. The first limiting surface and the second limiting surface are located on opposite sides of the slider in a second direction for limiting the slider in the second direction. The second direction is perpendicular to the first direction. The first hook further has a third limiting surface facing the slider, and the second hook further has a fourth limiting surface facing the slider. The third limiting surface and the fourth limiting surface are located on the side of the slider away from the mounting plate for limiting the slider in a third direction. The third direction is perpendicular to the first direction and the second direction.

[0017] Based on the thermal relay mounting structure provided by this embodiment, the slider can be limited in the second direction through the first limiting surface and the second limiting surface. In this way, when the slider slides, the slider can slide more accurately in the first direction and provide a force in the first direction to the guide rail. Thus, the phenomenon of the thermal relay being installed offset or not firmly clamped can be reduced. The slider can be limited in the third direction through the third limiting surface and the fourth limiting surface, so that the slider can be stably arranged on the mounting plate and prevent the slider from detaching from the mounting plate in the third direction.

[0018] In one design, the number of the second buckles is two, and the number of the third buckles is one. Along the second direction, the two second buckles are arranged side by side, and the third buckle is located between the two second buckles. In this way, the second buckle and the third buckle form a triangular layout structure, which has a relatively simple composition and is relatively stable when clamped.

[0019] In one design, the guide rail mounting assembly further includes a baffle, and the baffle and the third buckle are on the same side of the second buckle. The baffle is used to reduce the inclination of the thermal relay after installation.

[0020] Based on the thermal relay mounting structure provided by this embodiment, the guide rail mounting assembly further includes a baffle, and the baffle and the third buckle are on the same side of the buckle. In this way, when the thermal relay is inclined, the baffle can support the thermal relay, reduce the inclination of the thermal relay, and increase the mounting stability of the thermal relay.

[0021] In one design, the mounting plate includes a first connecting plate, a second connecting plate and a third connecting plate which are connected to each other. Along the first direction, the second connecting plate and the third connecting plate are located on opposite sides of the first connecting plate. The first buckle and the first set of mounting holes are arranged on the first connecting plate. The second set of mounting holes are arranged on the second connecting plate and the third connecting plate.

[0022] Based on the thermal relay mounting structure provided by this embodiment, when the thermal relay is assembled with the mounting plate through the first buckle and the first set of mounting holes, it will cover some areas between and even around the first buckle and the first set of mounting holes. In this application, the first buckle and the first set of mounting holes are arranged on the first connecting plate, and the second set of mounting holes are arranged on the second connecting plate and the third connecting plate. When the thermal relay is assembled with the device through the second set of mounting holes, the interference of the thermal relay to the assembly can be reduced or eliminated, which is convenient for the operator to fixedly connect the mounting plate and the device through the second set of mounting holes.

[0023] In one design, the third buckle is arranged on the second side of the first connecting plate, and the distance between the second side of the second connecting plate and the third connecting plate and the second side of the first connection is greater than the thickness of the third buckle.

[0024] Based on the thermal relay mounting structure provided by this embodiment, when the thermal relay mounting structure is mounted on a device without a guide rail, the third buckle will not interfere with the mounting process. The thermal relay mounting structure can be smoothly fixedly connected to the device through the second set of mounting holes, and at the same time, the device will not squeeze the third buckle, avoiding damage to the third buckle.

[0040] Figure 1 Schematic diagram of a thermal relay mounting structure provided by an embodiment of the present application, Figure 2 Shown is an exploded structure diagram of the mounting structure provided by an embodiment of the present application assembled with a thermal relay, Figure 3 Shown is a structure diagram of the mounting structure provided by an embodiment of the present application assembled with a thermal relay.

[0041] Please refer to Figures 1 to 3 , the thermal relay mounting structure 2 provided by the present application includes a mounting plate 21, a first buckle 22, a first set of mounting holes, and a second set of mounting holes. Among them, the mounting plate 21 has a first side for mounting the thermal relay 1. The first buckle 22 is connected to the first side of the mounting plate 21 and is used to insert into the slot 11 of the thermal relay 1. The first set of mounting holes is provided on the mounting plate 21 for fixedly connecting the mounting plate 21 to the thermal relay 1. The second set of mounting holes is provided on the mounting plate 21 for fixedly connecting the mounting plate 21 to the device.

[0042] In the present application, the mounting plate 21 mainly plays a role of support and connection. The mounting plate 21 can be a steel plate or some other alloy plate or composite material plate that can meet the support strength.

[0043] The first buckle 22 is connected to the first side of the mounting plate 21. The number of the first buckles 22 can be one or more. The first buckle 22 can be an integral structure or a split combination structure with the mounting plate 21. In an embodiment of the present application, the first buckle 22 can be an integral structure with the mounting plate 21, and the first buckle 22 can be formed by stamping the mounting plate 21.

[0044] The first buckle 22 can have a certain inclination relative to the mounting plate 21 to facilitate insertion into the slot 11 of the thermal relay 1.

[0045] The first set of mounting holes may include one or more first mounting holes 23, and the first mounting holes 23 are through holes that penetrate the mounting plate 21 in the thickness direction of the mounting plate 21. The second set of mounting holes may include one or more second mounting holes 24, and the second mounting holes 24 are through holes that penetrate the mounting plate 21 in the thickness direction of the mounting plate 21.

[0046] Please refer to Figure 3 , the thermal relay 1 installed using the thermal relay mounting structure 2 provided by the present application has a slot 11 adapted to the first buckle 22 and a first fixing hole 12 that cooperates with the first mounting hole 23.

[0047] The equipment mentioned in the present application may be equipment such as a distribution box or a control cabinet that requires the installation of the thermal relay 1, and the equipment is configured with a second fixing hole that cooperates with the second mounting hole 24.

[0048] Please combine with Figure 1 and Figure 3 , based on the thermal relay mounting structure 2 provided by the present application, when installing the thermal relay 1, the first buckle 22 can be first inserted into the slot 11 of the thermal relay 1 to hang the mounting plate 21 on the thermal relay 1. In this way, a preliminary installation limit can be achieved for the mounting plate 21. Then, the mounting plate 21 and the thermal relay 1 are fixedly connected by a fastener inserted through the first mounting hole 23 and the first fixing hole 12. After that, the mounting plate 21 and the equipment are fixedly connected by a fastener inserted through the second mounting hole 24 and the second fixing hole. In this way, through the thermal relay mounting structure 2 provided by the present application, the thermal relay 1 can be installed on the equipment.

[0049] Based on the above description, through the thermal relay mounting structure 2 provided by the present application, the thermal relay 1 can be installed on the equipment, and the thermal relay mounting structure 2 of the present application only includes a mounting plate 21, a first buckle 22, a first set of mounting holes and a second set of mounting holes, and has the characteristics of simple composition structure and convenient use, and can improve the installation efficiency of the thermal relay 1.

[0050] Figure 4 is a schematic diagram of a thermal relay mounting structure provided by an embodiment of the present application, Figure 5 shown is a schematic diagram of the structure after the thermal relay mounting structure provided by the embodiment of the present application is assembled with the thermal relay and the guide rail.

[0051] In some cases, the thermal relay 1 needs to be installed on the guide rail 3. Based on this, the thermal relay mounting structure 2 provided by the present application further includes a guide rail mounting component, and the guide rail mounting component is disposed on the second side of the mounting plate 21. The second side is opposite to the first side and is the side of the mounting plate 21 close to the equipment.

[0052] Please continue to refer to Figure 5, based on the thermal relay mounting structure 2 provided in this application, the thermal relay mounting structure 2 can be installed with other devices without a guide rail 3 through the second set of mounting holes, or assembled with devices having a guide rail 3 through the guide rail mounting assembly. In this way, the applicability of the thermal relay mounting structure 2 in this application can be enhanced.

[0053] Please continue to refer to Figure 4 , in some embodiments of this application, the guide rail 3 mounting assembly includes a second buckle 25 and a third buckle 26. The second buckle 25 is a fixed buckle, and the third buckle 26 is an elastic buckle. The second buckle 25 and the third buckle 26 are oppositely arranged on the mounting plate 21 along the first direction. The third buckle 26 has an elastic expansion amount along the first direction relative to the second buckle 25. The second buckle 25, the third buckle 26 and the mounting plate 21 form a guide rail mounting groove.

[0054] Specifically, in some embodiments of this application, the second buckle 25 and the mounting plate 21 can be an integral structure or a split structure. When the second buckle 25 and the mounting plate 21 are in a split structure, the second buckle 25 can be formed by stamping the mounting plate 21, and this structure is relatively simple.

[0055] In some embodiments of this application, the third buckle 26 is an elastic buckle, and the third buckle 26 and the second buckle 25 are oppositely arranged along the first direction. In this way, the third buckle 26, the second buckle 25 and the mounting plate area therebetween form a guide rail mounting groove.

[0056] Please combine Figure 4 with Figure 5 , when the thermal relay 1 is installed with the guide rail 3, the third buckle 26 moves in a direction away from the second buckle 25. In this way, the width of the guide rail mounting groove will increase, facilitating the clamping of the guide rail 3. After the guide rail 3 is snapped in, the third buckle 26 can move in a direction close to the second buckle 25 to clamp the guide rail 3 tightly. When it is necessary to disassemble the thermal relay 1, the third buckle 26 moves in a direction away from the second buckle 25. In this way, the width of the guide rail mounting groove will increase, facilitating the disassembly of the guide rail 3.

[0057] In summary, the thermal relay mounting structure 2 of this application includes a guide rail mounting assembly composed of a second buckle 25 and a third buckle 26. Through this guide rail mounting assembly, the thermal relay 1 can be easily clamped or disassembled with the guide rail 3, and the structure of the guide rail mounting assembly is simple and easy to implement.

[0058] It should be noted that there are many implementation manners of the guide rail mounting assembly. Only one example is illustrated in this application. In some other implementation manners of this application, the guide rail mounting assembly may also have other component structures. For example, both the second buckle 25 and the third buckle 26 are elastic buckles. When the thermal relay 1 is installed, the second buckle 25 and the third buckle 26 can move away from each other so that the guide rail 3 can be inserted into the guide rail mounting groove. After the guide rail 3 is inserted, the second buckle 25 and the third buckle 26 can approach each other to clamp the guide rail 3 tightly.

[0059] Figure 6 The figure shows an exploded structural view of the mounting structure provided by the embodiment of the present application. Figure 7 is Figure 6 a three-dimensional structural view of the slider in Figure 8 is Figure 6 a three-dimensional structural view of the slider from another perspective in

[0060] Please refer to Figures 6 to 8 In some implementation manners of the present application, the third buckle 26 includes a slider 261, an elastic member 262, and a mounting seat 263. The mounting seat 263 is connected to the mounting plate 21, and the mounting seat 263 has a positioning post 264 facing the second buckle 25. The slider 261 is provided with a third mounting hole 2611 and a fourth mounting hole 2612 that communicate with each other. The slider 261 is disposed on the mounting plate 21 at the mounting seat 263, and the slider 261 is slidably connected to the mounting plate 21. The mounting seat 263 passes through the third mounting hole 2611, and the positioning post 264 is inserted into the fourth mounting hole 2612. One end of the elastic member 262 is limited by the positioning post 264, and the other end of the elastic member 262 abuts against the hole wall of the fourth mounting hole 2612. The slider 261 can have an expansion and contraction amount in the first direction by relying on the elastic member 262.

[0061] Please combine Figures 6 to 8 When the third buckle 26 is assembled, the side of the slider 261 where the third mounting hole 2611 is provided faces the mounting plate 21, and the slider 261 is mounted on the mounting plate 21 at the mounting seat 263. In this way, the mounting seat 263 will pass through the third mounting hole 2611, and the positioning post 264 is inserted into the fourth mounting hole 2612. Then, the elastic member 262 is placed into the fourth mounting hole 2612. One end of the elastic member 262 is positioned by the positioning post 264, and the other end abuts against the hole wall of the fourth mounting hole 2612. In this way, the assembly of the slider 261 is completed.

[0062] When the thermal relay 1 is clamped or disassembled from the guide rail 3, the slider 261 moves away from the second buckle 25, and the slider 261 compresses the elastic member 262, and the elastic member 262 stores energy. After the thermal relay 1 is clamped to the guide rail 3, the slider 261 moves towards the second buckle 25, and the elastic member 262 releases elastic potential energy, so that the slider 261 can press tightly against the guide rail 3, thereby realizing the installation of the thermal relay 1 on the guide rail 3.

[0063] In summary, for the thermal relay installation structure 2 of the present application, the third buckle 26 is composed of a slider 261, an elastic member 262 and a mounting seat 263. The thermal relay 1 can be stably clamped to the guide rail 3 through the third buckle 26, and the structure of the third buckle 26 is simple and easy to implement.

[0064] It should be noted that in the present application, the mounting seat 263 and the mounting plate 21 can be an integral structure or a split structure. When the mounting seat 263 and the mounting plate 21 are an integral structure, the mounting seat 263 can be formed by stamping the mounting plate 21. When the mounting seat 263 and the mounting plate 21 are a split structure, the two can be connected by welding, bonding, screws and other means.

[0065] It should be noted that in the present application, the elastic member 262 can be a cylindrical spring or other shaped elastic members, such as a wavy elastic member.

[0066] It should also be noted that there are many implementation manners of the third buckle 26. Only one example is given in the present application. In some other implementation manners of the present application, the third buckle 26 can also adopt some elastic buckle structures existing in the prior art. For this, the present application will not elaborate.

[0067] Figure 9 The following shows a schematic diagram of the state when the thermal relay and the guide rail are assembled according to the embodiment of the present application. Please refer to Figure 9 In some implementation manners of the present application, a guiding inclined surface 2613 for facilitating the insertion of the guide rail 3 is further provided at one end of the slider 261 facing the second buckle 25.

[0068] Specifically, when the thermal relay 1 is assembled with the guide rail 3 through the thermal relay installation structure 2, it can be first hooked to the guide rail 3 through the second buckle 25, and then, the thermal relay 1 is pressed to make the guide rail 3 slide into the guide rail installation groove along the inclined surface. In this way, the installation process is very simple and labor-saving.

[0069] Please continue to refer to Figure 6, in some embodiments of the present application, the guide rail 3 mounting assembly further includes a first hook 27 and a second hook 28. The first hook 27 has a first limiting surface 271 facing the slider 261, and the second hook 28 has a second limiting surface 281 facing the slider 261. The first limiting surface 271 and the second limiting surface 281 are located on opposite sides of the slider 261 in the second direction for limiting the slider 261 in the second direction, and the second direction is perpendicular to the first direction. The first hook 27 further has a third limiting surface 272 facing the slider 261, and the second hook 28 further has a fourth limiting surface 282 facing the slider 261. The third limiting surface 272 and the fourth limiting surface 282 are located on the side of the slider 261 away from the mounting plate 21 for limiting the slider 261 in the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0070] Specifically, the slider 261 can be limited in the second direction by the first limiting surface 271 and the second limiting surface 281. In this way, when the slider 261 slides, the slider 261 can slide more accurately along the first direction and provide a force along the first direction to the guide rail 3. Thus, the phenomenon of the thermal relay 1 being installed offset or not firmly clamped can be reduced.

[0071] The slider 261 can be limited in the third direction by the third limiting surface 272 and the fourth limiting surface 282, so that the slider 261 can be stably arranged on the mounting plate 21 and prevent the slider 261 from detaching from the mounting plate 21 in the third direction.

[0072] Continuing to refer to Figure 6 , in some embodiments of the present application, the number of the second buckles 25 is two, and the number of the third buckles 26 is one. Along the second direction, the two second buckles 25 are arranged side by side, and the third buckle 26 is located between the two second buckles 25.

[0073] Specifically, the number of the second buckles 25 is two, and the number of the third buckles 26 is one. Along the first direction, the second buckles 25 and the third buckle 26 are arranged opposite to each other. Along the second direction, the two second buckles 25 are arranged side by side, and the third buckle 26 is located between the two second buckles 25. In this way, the second buckles 25 and the third buckle 26 form a triangular layout structure, which has a relatively simple composition and is relatively stable in clamping.

[0074] Please continue to refer to Figures 4 to 5 , in some embodiments of the present application, the guide rail 3 mounting assembly further includes a baffle 29. The baffle 29 and the third buckle 26 are located on the same side of the second buckle 25, and the baffle 29 is used to reduce the inclination of the thermal relay 1 after installation.

[0075] Specifically, please refer to Figure 4 and Figure 5, in some embodiments of the present application, the thermal relay 1 is hung on the guide rail 3 by the second buckle 25 and clamped with the guide rail 3 by the third buckle 26 pressing against the guide rail 3. If the force applied by the third buckle 26 towards the guide rail 3 is not directly facing the guide rail 3, or the contact surface between the third buckle 26 and the guide rail 3 is too small. Then, the thermal relay 1 clamped on the guide rail 3 is prone to tilting with the third buckle 26 as the fulcrum.

[0076] The guide rail mounting assembly of the present application further includes a baffle 29. The baffle 29 and the third buckle 26 are located on the same side of the second buckle 25. Thus, when the thermal relay 1 tilts, the baffle 29 can support the thermal relay 1, reduce the tilt degree of the thermal relay 1, and increase the mounting stability of the thermal relay 1.

[0077] In some embodiments of the present application, baffles 29 can be provided on both sides of the third buckle 26 along the second direction. Thus, it can not only reduce the tilt of the thermal relay 1 towards one side of the third buckle 26, but also reduce the tilt of the thermal relay 1 towards the other side of the third buckle 26.

[0078] Please refer to Figure 1 and Figure 5 , in some embodiments of the present application, the mounting plate 21 includes a first connecting plate 211, a second connecting plate 212 and a third connecting plate 213 connected to each other. Along the first direction, the second connecting plate 212 and the third connecting plate 213 are located on opposite sides of the first connecting plate 211. The first buckle 22 and the first set of mounting holes are provided on the first connecting plate 211. The second set of mounting holes is provided on the second connecting plate 212 and the third connecting plate 213.

[0079] Specifically, please combine Figure 1 with Figure 5 , when the thermal relay 1 is assembled with the mounting plate 21 through the first buckle 22 and the first set of mounting holes, it will cover some areas between and even around the first buckle 22 and the first set of mounting holes. In the present application, the first buckle 22 and the first set of mounting holes are provided on the first connecting plate 211, and the second set of mounting holes is provided on the second connecting plate 212 and the third connecting plate 213. When assembling the thermal relay 1 with the device through the second set of mounting holes, the interference of the thermal relay 1 to the assembly can be reduced or eliminated, facilitating the operator to fixedly connect the mounting plate 21 with the device through the second set of mounting holes.

[0080] Please continue to refer to Figure 5, the thermal relay mounting structure 2 provided in the present application provides two mounting methods for the mounting plate 21 and the device. One is that the mounting plate 21 is fixedly connected to the device through the second set of connection holes, and the other is that the mounting plate 21 is fixedly connected to the device through the guide rail 3 mounting assembly. Although only one of the mounting methods is actually used, in some embodiments of the present application, the thermal relay mounting structure 2 is provided with both the second set of mounting holes and the guide rail 3 mounting assembly. Thus, the thermal relay mounting structure 2 can be mounted to a device with a guide rail 3 and can also be mounted to a device without a guide rail 3.

[0081] Please continue to refer to Figure 5 , in some embodiments of the present application, the third buckle 26 is provided on the second side of the first connection plate 211, and the distance between the second side of the second connection plate 212 and the third connection plate 213 and the second side of the first connection is greater than the thickness of the third buckle 26. In this way, when the thermal relay mounting structure 2 is mounted to a device without a guide rail 3, the third buckle 26 will not interfere with the mounting process, and the thermal relay mounting structure 2 can be smoothly fixedly connected to the device through the second set of mounting holes. At the same time, the device will not squeeze the third buckle 26, avoiding damage to the third buckle 26.
