Abstract
Description
Technical Field
[0001] This utility model relates to the field of contactor installation, and in particular to a contactor installation structure. Background Technology
[0002] Contactors are divided into AC contactors and DC contactors, and they are used in power, distribution, and consumption applications. Broadly speaking, a contactor is an electrical device in industrial electricity that uses a coil to generate a magnetic field, causing contacts to close, thereby controlling the load. Because a contactor is a device that can quickly disconnect AC and DC main circuits and frequently connect and disconnect high-current control circuits, it is frequently used to control electric motors as the controlled object. It can also be used to control electrical loads such as factory equipment, electric heaters, machine tools, and various power units. Contactors not only connect and disconnect circuits but also provide undervoltage release protection.
[0003] Contactors have a large control capacity and are suitable for frequent operation and remote control, making them one of the important components in automatic control systems. Currently, contactors are generally fixed inside the distribution box with screws, requiring tools such as screwdrivers for disassembly and assembly, which is inconvenient. Therefore, there is an urgent need for an installation structure that allows for quick disassembly and assembly of contactors.
[0004] A contactor mounting structure is disclosed in publication number CN209691687U, comprising a base and a subbase. The subbase has a first extension and a second extension integrally formed on its two opposite end faces. The first extension is located above the second extension, and a gap exists between the two extensions. A slot is provided on the end face of the first extension facing the base. The base and the first extension are fixed together by screws, which pass sequentially from bottom to top through the first extension and the base. The second extension has a corresponding through groove to facilitate screwdriver insertion. During installation, the base and subbase are first joined together to achieve initial positioning. Then, the screw is inserted sequentially from bottom to top through the first extension and the base, locking them together. During screw tightening, the screwdriver can be inserted through the through groove at the lower end of the second extension of the subbase and extended to the screw head for operation, making the installation process convenient. Because the screw head is located at the lower end of the first extension, it is less likely to misjudge the screws of the coil terminals, and its creepage distance from the main circuit terminals is greater, thus ensuring higher safety and a more aesthetically pleasing appearance.
[0005] The aforementioned application addresses the problem that traditional contactors have screw heads located close to the coil terminals, making them difficult to distinguish from the screws at the coil terminals and prone to misjudgment. However, disassembly and assembly require the use of tools such as screwdrivers, which is not convenient. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a contactor mounting structure, which aims to improve the problem of needing to use tools such as screwdrivers for disassembly and assembly.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a contactor mounting structure, comprising: a contactor body, a wiring groove formed at the upper end of the front surface of the contactor body, a slide rail fixedly connected to the rear side of the contactor body, two mounting buckles slidably connected to the outer surface of the slide rail, two springs fixedly mounted on adjacent sides of the two mounting buckles, symmetrical inclined grooves formed at both ends of adjacent sides of the two mounting buckles, a slide rod slidably mounted on adjacent sides of the two mounting buckles, the slide rod slidably connected inside the inclined groove, the other end of the slide rod away from the inclined groove slidably connected inside another inclined groove, a push rod fixedly connected to the outer side of the middle of the slide rod, a pressing plate fixedly connected to the end of the push rod away from the slide rod, and a retaining strip provided on the side of the two mounting buckles away from the sliding rod.
[0008] Preferably, a T-shaped plate is fixedly connected to the side of the slide rail away from the contactor body, and a slide groove matching the T-shaped plate is opened on the rear side of both mounting buckles.
[0009] Preferably, slots are provided on the sides of the two card strips that are far apart.
[0010] Preferably, a mounting plate is connected between the two card strips, and the upper and lower sides of the mounting plate are respectively connected to the inside of the two card slots.
[0011] Preferably, both ends of the two slide bars are provided with rolling chambers, and a fixed rod is fixedly connected inside each rolling chamber, and a roller is rotatably connected to the outer wall of each fixed rod.
[0012] Preferably, each of the slide bars has a rolling groove at the end near the roller, and the size of the rolling groove matches the size of the roller.
[0013] Preferably, both ends of the two slide bars are tangents with the same angle as the inclined surface of the groove.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the contactor is installed on the mounting plate by the cooperation of the mounting buckle slot, push rod, pressing plate, inclined groove, slide rod and spring. The installation process does not require the use of screwdrivers or other tools, making disassembly and assembly more convenient.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1This utility model provides an embodiment of a contactor mounting structure, comprising: a contactor body 1, a wiring groove 2 formed on the upper end of the front surface of the contactor body 1, a slide rail 3 fixedly connected to the rear side of the contactor body 1, two mounting clips 6 slidably connected to the outer surface of the slide rail 3, two springs 14 fixedly mounted on adjacent sides of the two mounting clips 6, symmetrical inclined grooves 11 formed at both ends of adjacent sides of the two mounting clips 6, a slide rod 13 slidably mounted on adjacent sides of the two mounting clips 6, the slide rod 13 slidably connected inside the inclined groove 11, and the other end of the slide rod 13 slidably connected to another inclined groove. Inside the slide bar 11, push rods 8 are fixedly connected to the outer side of the middle part of the slide bar 13. Pressing plates 9 are fixedly connected to the ends of the push rods 8 away from the slide bar 13. The two mounting clips 6 are provided with locking strips 12 on the side away from the sliding plates 6. During installation, pressing the pressing plates 9 at both ends pushes the slide bar 13 to slide inward. The sliding of the slide bar 13 on the inclined groove 11 lifts the two mounting clips 6 to achieve up and down movement. Then it approaches the mounting plate 10. When the outer wall of the mounting plate 10 contacts the outer wall of the locking strip 12, the pressing plates 9 at both ends are stopped. The two mounting clips 6 are then locked onto the mounting strips of the mounting plate 10 under the pull of the two springs 14, thus completing the installation.
[0026] Reference Figure 2 A T-shaped plate 4 is fixedly connected to the side of the slide rail 3 away from the contactor body 1. The rear sides of the two mounting clips 6 are provided with sliding grooves 5 that match the T-shaped plate 4. The function of the mounting T-shaped plate 4 is to prevent the two mounting clips 6 from shaking back and forth during installation, thereby increasing the stability of the installation process.
[0027] Reference Figure 3 Each of the two mounting strips 12 has a slot 7 on the side that is far apart from each other. During installation, the mounting strips of the mounting plate 10 can be locked in the slot 7.
[0028] Reference Figure 1 An installation plate 10 is connected between the two clips 12. The upper and lower sides of the installation plate 10 are respectively connected to the inside of the two slots 7 to prevent the installation clips 6 from wobbling back and forth on the installation plate 10 after installation.
[0029] Reference Figure 4 and Figure 5 Both ends of the two slide rods 13 are provided with rolling chambers 18. The interior of each rolling chamber 18 is fixedly connected with a fixed rod 17, and the outer wall of each fixed rod 17 is rolledly connected with a roller 16, so that the slide rod 13 slides more smoothly inside the inclined groove 11.
[0030] Reference Figure 5Each slide bar 13 has a rolling groove 15 at one end near the roller 16. The size of the rolling groove 15 matches the size of the roller 16 to prevent the roller 16 from being unable to rotate inside the rolling chamber 18 due to insufficient space.
[0031] Reference Figure 5 Both ends of the two slide rods 13 are tangents with the same angle as the inclined surface of the inclined groove 11, so that the slide rods 13 can reach every inclined surface of the inclined groove 11 when sliding inside the inclined groove 11.
[0032] Working principle: During installation, press the pressing plates 9 at both ends. The pressing plates 9 push the push rod 8 inward. The push rod 8 pushes the slide rod 13 to slide on the inclined groove 11. The sliding of the slide rod 13 on the inclined groove 11 lifts the two mounting buckles 6 to achieve up and down movement. Then, it approaches the mounting plate 10. When the surface of the mounting plate 10 contacts the outer surface of the clip 12, stop pressing the pressing plates 9 at both ends. The two mounting buckles 6 will then engage on the mounting plate 10 under the pull of the two springs 14, thus completing the installation.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
