Referring to fig. 1 to 3, a low-voltage apparatus adapter mechanism according to an embodiment of the present invention is shown, which can be used to realize the matching connection of an auxiliary module f and a contactor c. By applying the scheme of the utility model, the contactor can be skillfully matched with the auxiliary module to use under the condition that the stroke of the contactor is greater than the total stroke of the auxiliary module, and the iron core is completely closed, so that the on-off function of the contactor and the auxiliary module is better realized.

20 and 30 can only make reciprocating linear movement in a direction perpendicular to the positioning plate 10, and the first coupling member 20 can pass through the receiving slot 11, but the second coupling member 30 cannot pass through the receiving slot 11.

Specifically, as shown in fig. 1, the first connecting member 20 has a first end portion 21 and a second end portion 22, the first end portion 21 can be connected to the contactor c and can move synchronously with the upper core 41 of the contactor c and the contact holder L2, and the second end portion 22 is inserted into the receiving groove 11 and forms a limiting passage 23.

Referring to fig. 2, the second connecting member 30 has a first bent plate 31 and a second bent plate 32, the first bent plate 31 has one end capable of being connected to the auxiliary module f and capable of moving synchronously with the contact holder L1 of the auxiliary module f, and the second bent plate 32 has an abutting body 33 and a stopper protrusion 34. Specifically, one end of the abutment body 33 may abut against the second end 22. The limiting protrusion 34 extends outwards from the other end of the abutting body 33 and can be accommodated in the limiting channel 23.

Preferably, as shown in fig. 3, the low-voltage apparatus adapting mechanism further has a reset element 35, the reset element 35 is accommodated in the limiting channel 23, one end of the reset element 35 abuts against the inner surface of the limiting channel 23, and the other end abuts against the limiting protrusion 34.

According to a preferred embodiment of the utility model, the abutment body 33 comprises a first connecting plate 331 and a second connecting plate 332. The second connecting plate 332 extends perpendicularly outwardly along one end of the first connecting plate 331. The top of the second end 22 of the first link 20 abuts against the first connecting plate 331 of the second link 30 by the restoring force of the restoring member 35, so that the first link 20, the restoring member 35 and the second link 30 form a stable relative initial position.

Specifically, in order to better achieve the limiting effect, the second end portion 22 abuts against the first connecting plate 331, and the limiting protrusion 34 is connected to the end of the second connecting plate 332.

According to an embodiment of the present invention, the reset member 35 is a compression spring, one end of the compression spring is connected to the first limit boss 341, and the other end of the compression spring is connected to the second limit boss 231.

As shown in fig. 2, it is more preferable that the second bending plate 32 is vertically connected to the other end of the first bending plate 31 such that the abutting body 33 has an L-shaped structure.

It should be noted that the low-voltage apparatus adapting mechanism of the present invention can be integrated as a part of the auxiliary module f, or as a part of the contactor c, or separately form a mechanism to exist independently, and this application is not limited in any way, but the solution formed by the above concept is within the scope of the present invention.

In order to facilitate a better understanding of the present case for those skilled in the art, the working principle of the adapting mechanism of the low voltage apparatus according to the present invention will be described in detail below with reference to fig. 5 and 6.

When the coil 43 of the contactor is energized, the upper iron core 41 of the contactor and the lower iron core 42 of the contactor start to close, the upper iron core 41 of the contactor pulls the first connecting piece 20 to move together, the second connecting piece 30 moves together with the first connecting piece 20 through the elastic connection, and the second connecting piece 30 drives the contact support L1 of the auxiliary module to move together. After the second connecting member 30 moves for a certain stroke, it collides with the positioning plate 10 and stops, and the contact bracket L1 of the auxiliary module f connected to the second connecting member 30 also stops, at this time, the contact bracket L1 of the auxiliary module f finishes the stroke, and the auxiliary module contact 51 completes the on-off action. Since the stroke of the upper core 41 of the contactor c is greater than the stroke of the contact holder L2 of the auxiliary module f, the upper core 41 of the contactor c, the contact holder L2 of the contactor c, and the first link 20 continue to move in synchronization, and the reset piece 35 is compressed and shortened until the upper core 41 of the contactor and the lower core 42 of the contactor are completely closed. At this time, the upper core 41 of the contactor finishes the stroke, and the contactor contact 61 completes the on-off operation.

When the coil 43 of the contactor is powered off, the upper iron core 41 of the contactor and the lower iron core 42 of the contactor start to separate, the upper iron core 41 of the contactor drives the contact support L2 of the contactor and the first connecting piece 20 to move together, after the upper iron core 41 of the contactor moves for a certain stroke, the top of the first connecting piece 20 contacts with the second connecting piece 30 and pushes the second connecting piece 30 to move, after the upper iron core 41 of the contactor and the housing 44 of the contactor collide with each other, the upper iron core 41 of the contactor stops moving, the upper iron core 41 of the contactor returns to the original position, at this time, the contact support L2 of the auxiliary module, the first connecting piece 20, the second connecting piece 30 and the contact support L2 of the contactor stop moving along with the upper iron core 41, the contact 51 of the auxiliary module completes the inferred action, and the contact 61 completes the inferred action.

It is to be noted that S1 shown in fig. 4 represents the stroke of the first link 20, which corresponds to the stroke of the contact holder L1 of the auxiliary module. S2 shown in fig. 4 represents the stroke of the second link 30, which corresponds to the stroke of the contactor contact holder L2 and the upper core 41. The first connecting member 20 and the second connecting member 30 move relatively by the difference between the stroke of the contactor c and the stroke of the auxiliary module f.

The utility model effectively solves the problem that the auxiliary module is matched with the contactor for use under the condition that the stroke of the auxiliary module is smaller than that of the contactor, and effectively expands the application range of the auxiliary module. Through the design, the auxiliary module does not need to be designed with a large stroke to be matched with a large-specification contactor for use. According to the low-voltage apparatus adapting mechanism disclosed by the utility model, the flexibility of product application is greatly improved, the solutions of products are enriched, and the low-voltage apparatus adapting mechanism has wide adaptability.
