[0001] The utility model relates to the technical field of AC contactors, in particular to a buckling structure of an AC contactor and a guide rail. Background Art

[0002] During the installation process, the AC contactor is generally equipped with a guide rail 01, and then the guide rail 01 is connected to other parts, such as Figure 4 As shown, in the prior art, a buckle 03 is arranged between the base 02 and the guide rail 01 of the AC contactor, and then a spring 04 is arranged in the buckle 03. The buckle 03 has an upper slot 05 that is engaged with the guide rail 01. During installation, the guide rail 01 needs to be inserted into the lower slot 06 first, and then the buckle 03 is pressed by hand to move the buckle 03 upward. After the guide rail 01 is inserted, the hand is released, and the buckle 03 moves downward, and the guide rail 01 is stuck in the position of the upper slot 05 and the lower slot 06. However, this type of connection method has a complicated installation procedure. During the installation process, the spring 04 needs to be pre-buried in the buckle 03 first, and then the buckle 03 is stuck on the base 02. In addition, during this process, the spring 04 is easy to fall off, resulting in failure to install the buckle 03. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the complex installation procedure of the guide rail and the base in the prior art. The installation process requires the spring to be embedded in the buckle first, and then the buckle is clamped on the base, and during this process, the spring is easy to fall off, thereby providing a buckling structure for the AC contactor and the guide rail that is convenient for buckling.

[0004] To this end, the utility model provides a buckling structure for an AC contactor and a guide rail, the AC contactor comprising a base, the base being provided with a connecting groove for the guide rail to be snapped into, at least one side of the base being provided with at least one snap-in groove, a spring being embedded in the snap-in groove, the snap-in groove being connected to the connecting groove, the spring having an initial state of being snapped in the snap-in groove and a compressed state of being snapped in with the guide rail, in which the guide rail is fixed in the connecting groove.

[0005] Furthermore: the base is also provided with a first channel for the spring to be embedded in the slot, the first channel is connected to the slot, and a block for preventing the spring from falling out is provided on the side wall of the first channel.

[0006] Furthermore: an end of the card slot facing away from the first channel is provided with a socket for the guide rail to be inserted and to contact the spring.

[0007] Further: an unlocking groove for allowing an external tool to extend into and separate the spring from the card block is provided at the connection between the first channel and the card slot.

[0008] Furthermore: the unlocking slot includes a movable end for inserting an external tool and an unlocking end capable of unlocking the spring and the card block, and the movable end and the unlocking end together form a "door"-shaped structure.

[0009] Furthermore: the base is provided with a conflicting groove that conflicts with the spring, and the highest point of the conflicting groove is at the highest point of the card slot and is on the same horizontal line.

[0010] The technical solution of the utility model has the following advantages:

[0011] 1. The utility model provides a buckling structure for an AC contactor and a guide rail. After the base is manufactured, the spring is first embedded in the slot. Then, after the guide rail is installed, it is only necessary to insert one end of the guide rail into the slot through the connecting slot to deform the spring under pressure. At this time, the guide rail is inserted into a relatively deep position of the slot, and the other end can be snapped into the buckling slot 31 of the base. After being snapped into the buckling slot 31, the operator releases the guide rail by hand, and the spring recovers its elasticity, pushing a part of the guide rail inserted into the slot outward, thereby buckling the guide rail with the base. This is superior to the prior art, and no buckling is required. In addition, the spring is pre-embedded in the slot, which avoids the problem of the spring falling during the installation process.

[0012] 2. The utility model provides a buckling structure for an AC contactor and a guide rail. When pre-embedded springs, it is only necessary to push the spring into the first channel until the spring enters the slot. At this time, one end of the spring contacts the inner wall of the slot, and the other end contacts the block, thereby fixing the position of the spring until the guide rail is inserted.

[0025] Example

[0026] The present embodiment provides a buckling structure of an AC contactor and a guide rail, the AC contactor comprises a base 1, the base 1 is provided with a connecting groove 3 for the guide rail 2 to be snapped into, at least one side of the base 1 is provided with at least one snap-in groove 4, a spring 5 is embedded in the snap-in groove 4, the snap-in groove 4 is communicated with the connecting groove 3, the spring 5 has an initial state of being snapped in the snap-in groove 4 and a compressed state of being snapped in with the guide rail 2, in which the guide rail 2 is fixed in the connecting groove 3.

[0027] The above specific improvements are: Figure 1 and Figure 2 As shown, after the base 1 is manufactured, the spring 5 must first be embedded in the slot 4. Then, after the guide rail 2 is installed, it is only necessary to insert one end of the guide rail 2 into the slot 4 through the connecting slot 3 to make the spring 5 deform under pressure. At this time, the guide rail 2 is inserted into a relatively deep position of the slot 4, and the other end can be snapped into the buckle slot 31 of the base 1. After being snapped into the buckle slot 31, the operator releases the guide rail 2 by hand, and the spring 5 recovers its elasticity, pushing a part of the guide rail 2 inserted into the slot 4 outward, so that the guide rail 2 is buckled with the base 1. This is better than the existing technology, and no buckling is required. In addition, the spring 5 is embedded in the slot 4, which avoids the problem of the spring 5 falling off during the installation process.

[0028] On the basis of the above embodiment: the base 1 is further provided with a first channel 6 for the spring 5 to be embedded in the slot, the first channel 6 is communicated with the slot 4, and a block 7 for preventing the spring 5 from falling out is provided on the side wall of the first channel 6.

[0029] The above specific improvements are: Figure 2 As shown, when pre-embedded spring 5, it is only necessary to push spring 5 into first channel 6 until spring 5 enters into slot 4. At this time, one end of spring 5 abuts against the inner wall of slot 4, and the other end abuts against block 7, thereby fixing the position of spring 5 until guide rail 2 is inserted.

[0030] On the basis of the above embodiment: the end of the card slot 4 facing away from the first channel 6 is provided with a socket 8 for the guide rail 2 to be inserted and abutting against the spring 5 .

[0031] The above specific improvements are: Figure 2 As shown, the end of the slot 4 facing away from the first channel 6 has a socket 8, and the socket 8 is used for the guide rail 2 to be inserted into and abut against the spring 5.

[0032] On the basis of the above embodiment: an unlocking groove 9 for allowing an external tool to extend into and separate the spring 5 from the clamping block 7 is provided at the connection between the first channel 6 and the clamping groove 4 .

[0033] The above specific improvements are: Figure 3As shown, when the spring 5 is used for a long time and its elasticity is insufficient to support the guide rail 2 or the spring 5 is rusted, the spring 5 needs to be replaced. A tool such as a screwdriver can be inserted into the unlocking slot 9 to pry the spring 5 so that the spring 5 breaks away from the restriction of the block 7 and slides out from the first channel 6.

[0034] Based on the above embodiment: the unlocking slot 9 includes a movable end 91 for inserting an external tool and an unlocking end 92 capable of unlocking the spring 5 and the block 7, and the movable end 91 and the unlocking end 92 form a "door"-shaped structure.

[0035] The above specific improvements are: Figure 3 As shown, the unlocking slot 9 includes a movable end 91 and an unlocking end 92. When taking out the spring 5, a screwdriver is passed through the movable end 91 to push the spring 5 to squeeze it so that the spring 5 passes over the block 7, and then a tool that can be inserted into the first channel 6 is used to hook the spring 5 out of the first channel 6.

[0036] On the basis of the above embodiment: the base 1 is provided with a conflicting groove 11 that conflicts with the spring 5 , and the highest point of the conflicting groove 11 is at the highest point of the slot 4 and is on the same horizontal line.

[0037] The above specific improvement is: by providing the abutment groove 11 , the spring 5 can be prevented from falling out of the socket 8 .

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
