Description

Technical Field

[0001] This utility model relates to the field of air conditioner electromagnetic contactor technology, specifically an air conditioner electromagnetic contactor. Background Technology

[0002] An air conditioner electromagnetic contactor is an electromagnetic switch mainly used to control the start and stop of the air conditioner compressor and fan. When the air conditioning system needs to start, the air conditioner controller sends a signal to the contactor, which automatically closes, sending power to the compressor and fan to start them. Conversely, when the system needs to stop, the contactor opens, disconnecting the power, and the compressor and fan stop working.

[0003] The prior art discloses patent application number "CN202321328644.4", which describes a DC electromagnetic contactor with a dust cover, including a lower contactor cover, an upper contactor cover, a hinged dust cover, and a wire wiping device. By providing mounting holes on the dust cover and adding a dust removal mechanism inside the dust cover, the above-mentioned problems are effectively overcome.

[0004] This electromagnetic contactor can only prevent the wire from breaking. In actual use, the electromagnetic contactor is usually installed by clipping it onto the guide rail. This installation method is not stable enough, which makes the electromagnetic contactor easy to shake and fall off the guide rail, thus affecting the safety of the electromagnetic contactor during use and making it inconvenient to use.

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 scope of protection of the present utility model.

[0025] like Figures 1 to 4 As shown, an air conditioner electromagnetic contactor includes a mounting base 1, an air conditioner electromagnetic contactor body 2 is snapped onto the front side of the mounting base 1, two symmetrically arranged rubber support plates 3 are mounted on the front side of the mounting base 1, and a double-ended screw 4 is rotatably connected inside the mounting base 1, with fixed handwheels 5 fixedly connected to both ends of the double-ended screw 4.

[0026] The outer surface of the double-ended lead screw 4 is threaded with two symmetrically arranged threaded plates 66. A U-shaped clamping plate 6 is fixedly installed on the rear side of each threaded plate 66. A rubber concave plate 7 is connected to the inner side of each U-shaped clamping plate 6. Through the arrangement of the U-shaped clamping plates 6, the two U-shaped clamping plates 6 can be adapted to clamp onto the guide rail. This allows the air conditioner electromagnetic contactor to be fixed onto guide rails of different sizes, thereby improving the compatibility of the air conditioner electromagnetic contactor. The mounting base 1 has two limiting slide rods 8 internally connected. Through the setting of the limiting slide rods 8, the two limiting slide rods 8 can limit... The movement trajectory of the two threaded plates 66 is controlled so that the two U-shaped clamping plates 6 can move and adjust smoothly to allow the air conditioner electromagnetic contactor to be engaged with the guide rail. The outer surfaces of the two limit slide rods 8 are slidably connected to the two ends of the threaded plates 66. Two locking pins 10 are fixedly connected to the left side of the mounting base 1. Two positioning grooves 9 are opened on the right side of the locking pins 10. Through the installation and use of the positioning grooves 9 and the locking pins 10, the locking pins 10 at the mounting base 1 can be inserted into the positioning grooves 9 of another mounting base 1 to connect multiple air conditioner electromagnetic contactors and ensure the stability of the air conditioner electromagnetic contactors.

[0027] Two symmetrically arranged circumferential elastic buckles 12 are installed on the front side of the mounting base 1. Both ends of the air conditioner electromagnetic contactor body 2 are connected to positioning plates 11. The circumferential elastic buckles 12 are used to limit the positioning plates 11. Through the setting of the circumferential elastic buckles 12, the circumferential elastic buckles 12 themselves have the ability of elastic deformation, so that the positioning plates 11 can be snapped into the circumferential elastic buckles 12 to fix the air conditioner electromagnetic contactor.

[0028] Two symmetrically arranged U-shaped seats 13 are fixedly connected to the front side of the mounting base 1. Both U-shaped seats 13 are rotatably connected to rubber swivel blocks 14 for fixing the air conditioner electromagnetic contactor body 2.

[0029] Two symmetrically arranged fixing plates 15 are connected to the front side of the mounting base 1. A telescopic plate 16 is slidably connected to the front side of each fixing plate 15. A limit plate 17 is slidably engaged on one side of each telescopic plate 16. Through the installation and use of the telescopic plate 16 and the limit plate 17, the telescopic plate 16 can be extended and adjusted to drive the limit plate 17 to be limited to the front of the air conditioner electromagnetic contactor, so as to further support the air conditioner electromagnetic contactor and prevent the air conditioner electromagnetic contactor from shaking. One side of the limit plate 17 passes through the telescopic plate 16 and extends to the other side of the telescopic plate 16. Connecting springs 18 are arrayed between the two fixing plates 15 and the telescopic plate 16. A rubber pad 19 is connected to one side of each of the two fixing plates 15 and the telescopic plate 16.

[0030] The two ends of the double-ended lead screw 4 pass through the mounting base 1 and extend to both ends of the mounting base 1. The rubber support plate 3 is used to position the air conditioner electromagnetic contactor body 2.

[0031] The air conditioner electromagnetic contactor body 2 has mounting grooves 20 on both sides. The mounting grooves 20 are adapted to the rubber swivel blocks 14. One side of the rubber swivel blocks 14 is engaged with both sides of the air conditioner electromagnetic contactor body 2 through the mounting grooves 20.

[0032] The working principle of the air conditioner electromagnetic contactor provided by this utility model is as follows:

[0033] By attaching the air conditioner electromagnetic contactor body 2 to the front of the mounting base 1, the four rubber support plates 3 at the mounting base 1 can initially support and fix the air conditioner electromagnetic contactor. Then, the mounting base 1 is placed on the guide rail, and then the fixing handwheel 5 on the double-ended screw 4 is rotated, so that the fixing handwheel 5 drives the double-ended screw 4 to rotate, and the two threaded plates 66 on the double-ended screw 4 can move towards each other. In this way, the two mounting bases 1 can drive the two U-shaped clamping plates 6 to be attached to the guide rail together, so as to clamp and fix the air conditioner electromagnetic contactor on the mounting base 1. At the same time, the rubber concave plates 7 at the two U-shaped clamping plates 6 can make the air conditioner electromagnetic contactor more securely attached, which helps to increase the stability of the air conditioner electromagnetic contactor when it is attached, prevents the electromagnetic contactor from easily shaking and falling off the guide rail, and improves the safety of the air conditioner electromagnetic contactor during use.

[0034] By compressing the two circumferential elastic buckles 12, the two positioning plates 11 can be engaged and positioned within the two circumferential elastic buckles 12 as the air conditioner electromagnetic contactor body 2 is installed. Then, the circumferential elastic buckles 12 are released, thus the circumferential elastic buckles 12 can act as a limit to fix the air conditioner electromagnetic contactor. Next, the rubber rotating blocks 14 at the two U-shaped seats 13 are rotated to the two mounting slots 20 of the air conditioner electromagnetic contactor body 2 to further fix the air conditioner electromagnetic contactor. Then, the two telescopic plates 16 with connecting springs 18 installed at the two fixing plates 15 are pulled, so that the limiting plates 17 at the two telescopic plates 16 can support and reinforce the front of the air conditioner electromagnetic contactor. At the same time, the rubber pads 19 at the fixing plates 15 and telescopic plates 16 can also play a protective role to protect the air conditioner electromagnetic contactor.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
