During the buckling process, the construction personnel need to manually press the elastic rod, and then push the elastic rod toward the side away from the connecting groove. Since the positioning rod conflicts with the inner side wall of the slot, when the elastic rod is pushed toward the side away from the connecting groove, elastic potential energy is formed at the connection position of the elastic rod and the positioning rod. When the guide rail is inserted into the connecting groove, the construction personnel release their fingers, and the elastic rod releases the elastic potential energy, so that the end of the elastic rod conflicts with the guide rail, so that the guide rail is fixed. This is better than the existing technology. There is no need to embed a spring in the elastic buckle, which effectively avoids the problem of failure of the elastic buckle installation due to the falling of the spring.

[0024] Example

[0025] The present embodiment provides an elastic buckle of an AC contactor, the AC contactor comprises a base 1, a guide rail 2 is connected to the base 1, a connecting groove 11 for the guide rail 2 to be inserted is provided on the base 1, a slot 12 for the elastic buckle to be inserted is provided on the side of the connecting groove 11, the elastic buckle is arranged in the slot 12, the elastic buckle comprises a positioning rod 3 transversely arranged in the slot 12 and an elastic rod 4 longitudinally arranged in the slot 12, the positioning rod 3 abuts against the inner side wall of the slot 12, the elastic rod 4 has a connecting block 41 buckled with the guide rail 2, the elastic rod 4 has a connected state in which the connecting block 41 is buckled with the guide rail 2 and a disengaged state in which the connecting block 41 is separated from the guide rail 2, when the elastic rod 4 switches from the connected state to the disengaged state, the elastic rod 4 moves toward the side away from the guide rail 2.

[0026] The above specific improvements are: Figure 1 and Figure 2 As shown, compared with the prior art, the elastic buckle omits the setting of the spring and uses the deformation force of the elastic buckle itself to buckle the guide rail 2. During the buckling process, the construction personnel are required to manually press the elastic rod 4 and then push the elastic rod 4 toward the side away from the connecting groove 11. Since the positioning rod 3 conflicts with the inner wall of the slot 12, when the elastic rod 4 is pushed toward the side away from the connecting groove 11, elastic potential energy is formed at the connection position between the elastic rod 4 and the positioning rod 3. After the guide rail 2 is inserted into the connecting groove 11, the construction personnel release their fingers, and the elastic rod 4 releases the elastic potential energy, so that the end of the elastic rod 4 conflicts with the guide rail 2, so that the guide rail 2 is fixed. This is better than the prior art. There is no need to pre-embed the spring in the elastic buckle, which effectively avoids the problem of failure of the elastic buckle installation due to the falling of the spring.

The elastic rod 4 and the positioning rod 3 are also arranged in a "T"-shaped structure. Both ends of the positioning rod 3 are clamped inside the first accommodating slot 121. When the elastic rod 4 moves toward the side away from the guide rail 2, due to the limitation of the inner wall of the first accommodating slot 121, the connection between the elastic rod 4 and the positioning rod 3 will be deformed, and elastic potential energy will be accumulated after the deformation. When the guide rail 2 is placed in the connecting slot 11, the elastic rod 4 is released and reset, so that the end of the elastic rod 4 is clamped with the guide rail 2.

[0029] On the basis of the above embodiment: an abutment structure 5 is arranged between the elastic rod 4 and the second accommodating groove 122, and the abutment structure 5 includes a abutment block 51 located in the second accommodating groove 122 and a abutment rod 52 arranged in the elastic rod 4.

[0032] The above specific improvements are: Figure 2 As shown, the auxiliary mechanism 6 includes slide grooves 61 arranged on both sides of the elastic rod 4 and a slider 62 arranged on the second accommodating groove 122. When the elastic rod 4 switches from the release state and the connection state, the slider 62 moves along the extension direction of the slide groove 61.

[0033] On the basis of the above embodiment: a plug-in structure 7 is provided between the first receiving groove 121 and the positioning rod 3 , and the plug-in structure 7 includes a plug-in strip 71 provided on the positioning rod 3 and a plug-in groove 72 opened in the first receiving groove 121 and adapted to the plug-in strip 71 .
